This work was supported with funds from the National Natural Science Foundation of China (NSFC) Nos. 82374564 (to YJD) and Nos. 82074566 (to YJD) and from Sun Guojie Inheritance Base for TCM Acupuncture-Moxibustion of World Federation of Acupuncture-Moxibustion Societies in Wuhan, China (World Federation of Acupuncture-Moxibustion Societies [2019] No. 26) (to YJD) and the National Famous TCM Inheritance Studio construction project of the National Administration of Traditional Chinese Medicine, China (the National Administration of Traditional Chinese Medicine [2022] No. 5) (to YJD).

All experiments were carried out following the National Institutes of Health Guide for the Care and Use of Laboratory Animals and were approved by the Hubei Provincial Center for Disease Control and Prevention Laboratory Animal Management and Use Committee. A total of 18 3-month-old female Sprague-Dawley (SD) rats weighing 220-250 g were used for the test. All rats were maintained on a 12 h light/dark cycle at 23 &#177; 1 &#176;C and 40%-50% humidity, with free access to food and water. Following a one-week acclimatization period, during which the rats were allowed to habituate to the laboratory conditions, the experiments were initiated.
1. Model development
<ol>
	<li>The experimental design is shown in Figure 1. Randomly divide 18 Sprague-Dawley 3-month-old female rats weighing 220-250 g into control, model, and TEAT groups. Each group consists of 6 rats.</li>
	<li>Inject the model group and TEAT group daily with D-galactose (D-gal; 120 mg/kg/day), while the control group receives saline injections (120 mg/kg/day), for 7 weeks (49 days) in the lower ventral area22. The injection should be administered daily between 8:00 and 9:00 a.m.</li>
	<li>Weigh the rats on the 7th day of each week between 9:00 and 10:00 a.m. The experiment lasted for 49 days. Bury the threads every 14 days on the 14th, 28th, and 42nd days. Fix the time for each thread embedding between 9:00-12:00 am.</li>
	<li>Continue intraperitoneal administration of D-galactose for 7-weeks to induce Alzheimer&#39;s disease-related pathological manifestations in rats22.</li>
</ol>
2. Preparation for TEAT
<ol>
	<li>Sterilize surgical instruments such as ophthalmic scissors, trays, and tweezers and disinfect. Clean the surfaces in the operating room environment thoroughly and disinfect.</li>
	<li>Prepare the surgical platform by laying a small animal heating pad flat on the surface, followed by draping with a sterile towel. Subsequently, place the cleaned and disinfected operating board smoothly on top, with the rough side facing upwards. Then, switch on the heating pad and set the temperature to 32 &#176;C.</li>
	<li>For the procedure, select a No. 6 disposable thread-embedding needle with a diameter of 0.6 mm and a 5-0 absorbable surgical suture (collagen suture) with a length of 2 cm. Cut the 2 cm 5-0 absorbable surgical suture into 0.5 cm and 0.2 cm pieces using ophthalmic scissors. Soak the cut thread in 0.9% saline and set aside.</li>
	<li>Wash hands with soap and water for 20 s, and then dry them. Afterward, wear sterile gloves.</li>
	<li>Anesthetize the rats with an IP injection of chloral hydrate (300 mg/kg) in the lower ventral area, ensuring that anesthesia is confirmed when animals are unresponsive in a surgical plane, based on the lack of response from a toe pinch test, and maintaining a stable physiological state. Additionally, to prevent corneal dryness and potential damage while the rats are under anesthesia, apply a generous amount of veterinary ointment to the eyes, ensuring they remain lubricated throughout the procedure. 
	NOTE: It is recommended to anesthetize the rat, as it is painful for them to experience the piercing.</li>
</ol>
3. Thread-embedding operation for Baihui (GV 20)
<ol>
	<li>Locate the acupoint Baihui (GV 20) in rats at the right midpoint of the parietal bone (Figure 2A). Position the rats to fully expose the head, with the ears pulled forward to approximate the method used in humans for connecting the ear apex lines. Identify the Baihui (GV 20) point by palpating the central longitudinal ridge of the skull and pinpointing the location roughly at its midpoint. Confirm this acupoint further at the level where the ears would make contact with the head if laid flat, aligning with the intersection of the sagittal suture and the parietal bone. Use a marker to mark Baihui (GV 20).</li>
	<li>Shave the head area around the acupoint of the rat using a trimmer (usually an electric men&#39;s beard trimmer).</li>
	<li>Prior to surgery, disinfect the acupoints and surrounding skin by applying a 0.5% iodine solution in circular motions, starting from the center, and moving outwards. Subsequently, perform a triple disinfection process: use the iodophor 3x, each followed by an application of alcohol to ensure proper decontamination and prepare the site for aseptic technique.</li>
	<li>Use forceps to clamp out the 0.2 cm absorbable surgical suture soaked in saline and place it in the front end of the needle tube. Then, connect it to the needle core.</li>
	<li>Pinch the area around Baihui (GV 20) with thumb and index finger on one hand, while holding the needle with the other.</li>
	<li>Insert the needle horizontally and quickly at a 15&#176; angle to the skin surface, 0.1 cm below the Baihui (GV 20) point, while pinching the skin (Figure 3A).</li>
	<li>After the needle tip reaches 0.1 cm above the Baihui (GV 20) point, push the needle core while retracting the needle tube to fully implant the 0.2 cm absorbable surgical suture into the subcutaneous tissue of the acupoint (Figure 3B).</li>
	<li>Slowly remove the needle, making sure no suture is exposed. Press the needle hole with sterile dry cotton for 10 s to prevent bleeding. If the thread is outside the body after embedding the line at acupoints, extract it and re-operate.</li>
</ol>
4. Thread-embedding operation for Shenshu (BL 23)
<ol>
	<li>The acupoint Shenshu (BL 23) in rats is located 5 mm lateral to the 2nd lumbar vertebra (Figure 2B). First, locate the 6th lumbar vertebra based on the hip tubercle of the rat. Then locate the 2nd lumbar vertebra by counting upward four vertebral bodies. Shenshu (BL 23) will be 5 mm lateral to it23. 
	NOTE: The combination of the Baihui (GV 20) and Shenshu (BL 23) acupoints is a frequently utilized set in Traditional Chinese Medicine (TCM) theory for the prevention and treatment of cerebral disorders. As confirmed by previous research20,21, this acupoint pairing has been established for its efficacy.</li>
	<li>Use a marker to mark Shenshu (BL 23). Shave the back and waist area around the acupoint of the rat using a trimmer (usually an electric beard trimmer).</li>
	<li>Prior to surgery, disinfect the acupoints and surrounding skin by applying 0.5% iodine solution in a circular motion, starting from the center and moving outwards. Subsequently, perform a triple disinfection process: use the iodophor three times, each followed by an application of alcohol to ensure proper decontamination and preparation of the site for aseptic technique.</li>
	<li>Use forceps to clamp out the 0.5 cm absorbable surgical suture soaked in saline and place it in the front end of the needle tube. Then, connect it to the needle core.</li>
	<li>Stretch the skin with the index and middle fingers of the pressing hand or the thumb and index fingers. Hold the needle with the puncturing hand.</li>
	<li>Quickly insert the needle perpendicularly into the point 0.25 cm below the Shenshu (BL 23). See Figure 4A.</li>
	<li>After the needle tip reaches 0.5 cm under the skin, adjust the needle tip, making the direction of insertion centripetal, forming a 45&#176; angle with the skin surface and obliquely insert 0.5 cm (Figure 4B). 
	NOTE: It is important to exercise caution when needling the Shenshu (BL 23), which is located near the kidney. Deep insertion or repeated lifting and thrusting of the needle can cause damage. Therefore, we recommend an insertion depth of around 0.3-0.6 cm.</li>
	<li>Push the needle core while retracting the tube and fully implant the 0.5 cm absorbable surgical suture into the acupoint&#39;s muscle tissue of the acupoint (Figure 4C).</li>
	<li>Slowly pull out the needle, ensuring no suture is exposed. Then, press the needle hole with sterile dry cotton for 10 s to prevent bleeding. If the thread is outside the body after embedding the line at acupoints, extract it and re-operate.</li>
</ol>
5. Post-operative care
<ol>
	<li>Postoperatively, place the rat on a small animal heating pad set at a temperature of 32&#176;C to facilitate recovery from anesthesia.Ensure the animal is fully conscious and its condition is satisfactory before returning it to its housing enclosure.</li>
	<li>After surgery, observe signs of sterile inflammatory responses in the affected area within a week. These signs may include redness, swelling, or a pus-like discharge. Typically, these symptoms do not require any treatment. However, if there is an excessive amount of exudate, drain and disinfect the affected area. In such cases, apply erythromycin ointment until the wound fully recovers.</li>
</ol>
6. Behavioral testing and histological examination
<ol>
	<li>Following the intervention, at week 8, perform the Morris Water Maze (MWM) experiment2,24 to evaluate their learning and memory capabilities. Perform the learning trials over 5 days, with four trials per day. Then administer a probe trial after 24 h from the last acquisition day.</li>
	<li>Perform statistical comparisons using statistical analysis software. Analyze the behavioral data of learning ability by one-way analysis of variance (ANOVA) and post-hoc Tukey&#39;s test. Assess the significance of escape latency data by two-way repeated measure analysis of variance (ANOVA) followed by the post-hoc Bonferroni test. A value of p &#60;0.05 is considered significant in all tests.</li>
	<li>After the behavioral assessment, anesthetize the rats as above and euthanize with intraperitoneal injections of 150 mg/kg body weight of pentobarbital sodium.</li>
	<li>Fix the rat&#39;s brain through perfusion using 4% paraformaldehyde perfused via the vascular system25.
	<ol>
		<li>Insertion and fixation of the gavage needle
		<ol>
			<li>Prepare a 12G needle and ensure it is straight and suitable for passing through the ventricle of the rat. Locate the ventricle of the rat, which is typically the left ventricle, and insert the needle through it into the ascending aorta. This step requires precision and a good understanding of rat anatomy.</li>
			<li>Once the needle is in place, use a hemostat to clamp the gavage needle near the point where it enters the aorta. This will help to secure the needle and prevent it from moving.</li>
			<li>Ensure that the clamp is tight enough to hold the needle securely but not so tight as to damage the aorta or impede blood flow. The gavage needle should remain in the ascending aorta throughout the procedure to maintain proper perfusion.</li>
		</ol>
		</li>
		<li>Perfusion with normal saline
		<ol>
			<li>Prepare a 50cc syringe without a needle for the perfusion. Attach the other end of the gavage needle, which is outside the rat&#39;s body, to the syringe filled with normal saline.</li>
			<li>Make a small incision to cut the right atrial appendage to allow blood to flow out of the heart. This step ensures that the blood is displaced by the saline during perfusion.</li>
			<li>Begin injecting the normal saline into the ascending aorta at a steady and constant rate. This will flush out the blood and prepare the tissues for fixation.</li>
			<li>Monitor the fluid coming out of the right atrial appendage and be prepared to change the syringe as needed to maintain a continuous perfusion with fresh saline. 
			&#8203;placed, prepare to perfuse with the fixative.</li>
			<li>Replace the syringe containing saline with one containing 4% paraformaldehyde, a commonly used fixative in histology. Proceed with the perfusion using the paraformaldehyde to fix the tissues in place for subsequent processing and analysis. 
			NOTE: Throughout this procedure, it is crucial to maintain aseptic techniques to prevent infection and to handle the rat gently to minimize injury. Additionally, all personnel involved should be trained in the technique to ensure consistency and effectiveness.</li>
		</ol>
		</li>
	</ol>
	</li>
	<li>Remove the rat brain and place it in a specimen bottle containing 4% paraformaldehyde for 24-48 h at 4 &#176;C25,26. Perform ethanol dehydration and xylene treatment step by step, followed by conventional continuous coronal sections (4-5 &#181;m) for measurement. Evaluate the morphology and loss of hippocampal neurons in each group using Hematoxylin and Eosin (H&#38;E) staining (200x). 
	NOTE: A necropsy examination to assess for gastrointestinal (GI) lesions was not conducted on the rodents based on the absence of clinical signs indicative of GI disturbances throughout the experimental period. The animals exhibited no overt adverse reactions that would suggest the presence of such pathologies.</li>

Improving Cognitive Functions in Rats via Thread-Embedding Acupuncture Therapy

The authors declare that they have nothing to disclose.

Intervention time 
The etiology of AD is complex, and its pathogenesis remains uncertain. Currently, there is no effective treatment for the disease, and its course is irreversible. Therefore, the academic community has reached a consensus on the importance of focusing on the prevention and treatment of AD. The prevention and treatment strategies for AD emphasize early intervention, following the TCM concept of treating conditions before they occur, emphasizing treatment before its onset, transmission, and recurrence. The accumulated research in humans29,30 and rodents31,32 has shown that early acupuncture and moxibustion intervention can achieve significant results without apparent side effects, making it a promising potential method for preventing and treating AD. Therefore, this study administered treatment during the modeling process. TEAT was implemented at the beginning of the D-gal intraperitoneal injection.
Acupoint selection 
AD is a severe neurodegenerative disease that primarily affects the brain regions responsible for memory, language, reasoning, and social behavior. The brain (Nao) is considered the sea of marrow (Sui) in TCM. The marrow (Sui) is made of essence (Jing), a substance unique in TCM that is believed to be the body&#39;s essential constitutional strength, vitality, and resistance. Essence (Jing) is mainly stored in the kidneys (Shen). If the kidney essence (Shen Jing) is weak, the brain (Nao) may lack nourishment, and cognitive impairment may occur. Therefore, TCM suggests tonifying the kidneys and benefiting the essence (Jing) can help improve brain function. The brain can be directly influenced by certain meridians, such as the Governor vessel (GV) and the bladder meridian of foot Taiyang (BL), as they enter the brain. The combination of the Governor vessel (GV) and the bladder meridian of foot Taiyang (BL) used for preventing and treating AD is highly utilized33,34. Baihui (GV 20) is an acupoint located at the vertex of the head and is part of the Governor vessel. According to literature, in studies using acupuncture and moxibustion for the prevention and treatment of AD, Baihui (GV 20) has the highest frequency of occurrence and is considered a critical point in the formula35. The Shenshu (BL 23) is an acupoint on the bladder meridian of foot Taiyang. It is located 1.5 cun lateral to the lower border of the spinous process of the second lumbar vertebra. As the kidney back transporting-Shu point, it can strengthen all aspects of the kidneys, including kidney yin, yang, essence (Jing), and qi. Acupuncture and moxibustion at Baihui (GV 20) and Shenshu (BL 23) may improve cognitive function and alleviate AD symptoms in various ways36,37.
Interval time 
The operating standards of TEAT38 dictate that the treatment interval and course of treatment should be determined based on the disease&#39;s condition and the selected operating site, with an interval of 1 week to 1 month. The course of treatment can range from 1 to 5 times. This suggestion can also be followed in experimental animal research. Based on the reviewed literature39, treatment is generally administered once a week or every 2 weeks, with most cases involving 4-8 consecutive treatments. The experiment lasted 49 days, during which the threads were buried on the 14th, 28th, and 42nd days.
Tool and methods 
Various thread-embedding tools are used in current experimental animal research. These include No. 740 or No. 941 disposable thread-embedding needles, self-reinvented needles, and No. 12 lumbar puncture needle42. The self-reinvented needles use No. 5-7 syringes as the tube and an appropriate filiform needle for the needle core. The needle tip has been pre-smoothed in advance. For example, in a study using SD rats weighing 250 &#177; 20 g (month age not specified in the text), choose the No.7 syringe and the 0.30 x 0.40 mm filiform needle43,44. However, the self-reinvented needles must be strictly disinfected, making them unable to be used widely. If the needle tip is too large or sharp, it can damage blood vessels and nerves, increasing the likelihood of bruising45. Lumbar puncture needles, which have a large diameter and sharp tips, are more likely to damage blood vessels and nerves. The disposable embedding needle is the most used in clinical practice39. It is more convenient to use and safer to operate compared to self-reinvented needles and lumbar puncture needles, making it ideal for TEAT. Additionally, the goal of the experiment is to improve human health. Therefore, animal studies should reflect the clinical situation. Hence, it is advisable to use disposable thread-embedding needles as thread-embedding tools.
Catgut was the primary thread material used in TEAT, but due to tissue rejection and animal-derived ingredients, it has been replaced by biosynthetic absorbable surgical sutures. Sutures are available in various sizes and should be matched to the needle, such as No.7 for 4-0 or 3-0 sutures. In animal research, 3-041, 4-046, and 5-047 are mainly used. Most sutures are 1-2 cm long. However, rodents have much smaller bodies than humans, so there is a lack of appropriate size for their body size. Therefore, researchers must cut sutures into 0.2-0.5 cm segments to make them suitable for rodents. Therefore, it is recommended that sutures be rinsed with clean and sterile distilled water or saline after cutting and before soaking for later use or immediate application to reduce the risk of infection46.
Some studies have proposed detailed requirements for the embedding method, such as rapidly inserting needles into the acupoint from about 0.5 cm below the acupoint towards the acupoint48. This is important because rodents are small. In addition to having abundant muscle tissue in their lower limbs, their subcutaneous tissue and muscle layers in the head, back, and abdomen is relatively weak. Therefore, the issue of TEAT&#39;s insertion points and insertion angle in animal research needs to be emphasized here. When performing TEAT on the lower limbs of rodents, direct needling at the acupoints is feasible. As for the body, it is recommended to insert the needle below the acupoints (the distance can be flexibly adjusted according to the length of the thread body) using oblique needling (&#60;45&#176;) or flat needling (&#60;15&#176;) to avoid damage to the internal organs.
Potential of TEAT for the prevention and treatment of Alzheimer&#39;s disease 
Recently, research on TEAT is emerging, although its effects and mechanisms remain elusive. As mentioned above, TEAT can improve AD-related risk factors such as obesity13,14, diabetes15, insomnia16, postmenopausal osteoporosis17, and depression18. It has a beneficial effect on learning and memory impairment in VD rats19. TEAT regulates lipid metabolism through the PPAR pathway to ameliorate tissue injury in exercise-induced fatigued rats49 and exerts anti-inflammatory and analgesic effects in intermittent cold stress-induced mice through the TRPV1 pathway50. In the present study, we demonstrated that thread-embedding treatment on AD-like rats could alleviate learning and memory impairments by ameliorating spatial memory loss and reducing degenerated cells in hippocampal CA1 regions. However, due to the current research&#39;s lack of uniformity and standardization in several critical elements of TEAT operation, including the embedding method, embedding tool, thread, and embedding interval period, this article mainly discusses the critical operational elements of TEAT in experimental research. This research was only a preliminary exploration of the effect of TEAT on AD, which required much more complement and improvement in clarifying the exact molecular and interaction between them. Nevertheless, it offered a new trial for the inevitable AD process, which may somehow relieve the heavy burden on the public health care system.

Thread-embedding acupuncture (TEA) involves embedding catgut or absorbable sutures into acupoints using a special needle. This technique has a prolonged effect until the sutures are absorbed and degraded. It provides continuous and sustained stimulation to the acupoints for a week or longer1, achieving a comparable outcome without the necessity for daily repetitive procedures2. This reduces the number of patients seeking medical treatment, thus conserving medical resources to some extent. In recent years, TEAT has been increasingly used in various medical fields in China, including internal medicine, external medicine, dermatology, facial features, gynecology, and pediatrics3. Studies have shown that it is effective in producing long-term and reliable effects for certain chronic and complex diseases, such as epilepsy4 and facial nerve paralysis5. It has the advantages of minimal trauma and simple operation6. Additionally, the treatment costs of TEAT have been reported to be lower than those of electroacupuncture (EA)7. Therefore, TEAT is increasingly valued in clinical and scientific research.
Alzheimer's disease (AD) is a neurodegenerative condition that progresses over time. Its pathophysiological process begins to accumulate approximately 20 years before clinical symptoms appear, but its mechanism is still not fully understood8. Given the limited availability of effective drugs for AD, research is increasingly focusing on the prodromal and preclinical stages of the disease9. Prevention is a crucial strategy for addressing the development and progression of AD9,10. In recent years, traditional Chinese medicine (TCM) has made significant progress, and it is expected to offer new possibilities for preventing and treating AD11,12. As a subtype of acupuncture, TEAT is preferred over other therapies due to its wide treatment range, minimal trauma, simple operation, low treatment frequency, and long-lasting efficacy6. Emerging literature suggests that TEAT may benefit individuals with obesity13,14, diabetes15, insomnia16, postmenopausal osteoporosis17, and depression18, all of which are risk factors for AD. It also improves senescence in aging rats by regulating mitophagy2, improves spatial learning and memory impairment, alleviates pathological damage of the hippocampus, and inhibits inflammation response in vascular dementia (VD) rats19. It appeared attractive to figure out whether TEAT could also act on pathological processes during AD.
The current research lacks uniformity and standardization in several critical elements of TEAT operation, including the embedding method, embedding tool, thread, and embedding interval period. This lack of standardization affects the evaluation of the therapy's effect and the exploration of related mechanisms and restricts external promotion and communication. Prior research20,21 has demonstrated that intraperitoneal administration of D-galactose (D-gal) can induce Alzheimer's disease-like pathological changes in rats, including neuronal degeneration and cognitive impairments. Furthermore, electroacupuncture at the Baihui(GV20) and Shenshu(BL23) has been shown to effectively ameliorate cognitive decline, mitigate neuroinflammation, and reduce neuronal damage. This study takes Alzheimer's disease-like model rats as an example to introduce the selection of acupoints and the operation process and precautions of TEAT under this model. It discusses the critical operational elements of TEAT in experimental research to provide a reference for future studies.

operation procedure and precautions of thread-embedding acupuncture therapy in alzheimer

Thread-embedding therapy (TEAT) is a treatment that prevents and manages diseases by inserting a biodegradable suture into an acupoint, providing long-lasting stimulation. TEAT is a simple approach that avoids the discomfort of regular acupuncture and provides sustained therapeutic effects. This article discusses the potential impact of TEAT on the learning and memory abilities of rats with Alzheimer&#39;s disease-like symptoms. Since chemically induced neuronal degeneration and cognitive impairments in rats does not entirely reflect the true pathological changes observed in Alzheimer&#39;s disease. Consequently, our research group has designated these manifestations as Alzheimer&#39;s disease-like symptoms. A protocol has been established to outline the selection of acupoints, the operation process, and necessary precautions for the head and lower back. The experiment was conducted on three groups: a control group, a model group, and a TEAT group, each containing 6 rats. To induce Alzheimer&#39;s disease-like symptoms, rats were intraperitoneally injected with D-galactose for 7 weeks (49 days). The rats in the TEAT group received acupoint catgut embedding treatment. Following the intervention period, a Morris Water Maze (MWM) was conducted to evaluate the rats&#39; learning and memory. Subsequently, the rats were sacrificed, and their brain tissue was examined. A histological examination was performed to understand the effects of TEAT on the pathology of rats exhibiting symptoms of Alzheimer&#39;s disease. This study suggests that TEAT may improve learning and memory in rats with Alzheimer&#39;s disease-like symptoms, indicating a potentially promising new treatment approach for this neurodegenerative condition.

This article introduces the specific operation method of TEAT in Alzheimer&#39;s disease-like rats. It discusses the critical operational elements of TEAT in experimental research to provide a reference for future studies.
TEAT improves learning in Alzheimer&#39;s disease-like rats 
As illustrated in the flowchart (Figure 5), during the adaptive training period, it was observed that rats in each group were observing the surrounding environment while swimming. The analysis of swimming speed (Figure 6) showed no significant difference among the groups, indicating consistent baseline levels of movement speed and visual perception. Any observed differences in experimental results were not due to variations in movement ability or visual perception.
The rats underwent 5 days of platform search training. In Figure 7A, it can be observed that the movement trajectories of each group of rats differed in the early and late stages of training. On day 2, most of the escape-driven rat groups swam randomly. However, on day 5, the rats in the control group swam with direction, while the model group rats swam randomly along the pool wall. The TEAT group rats&#39; movement became denser in the target quadrant. The experiment measured escape latency, with shorter latency indicating stronger abilities. Figure 7B shows that the model group exhibited reduced learning and memory abilities compared to the control group. However, the TEAT group showed a significant improvement in spatial reference memory impairment in rats with AD-like pathology.
TEAT improves spatial memory in Alzheimer&#39;s disease-like rats 
In the probe trial, the location where the animal spends time indicates spatial bias27. Rats use four primary methods to search for platforms: edge-based, random-based, trend-based, and linear-based28. The results indicate that each group of rats employed different search strategies (Figure 8A). The control group primarily used linear and directional search strategies, suggesting a strong memory and ability to recall the platform&#39;s location. In contrast, the rats in the model group exhibited an edge-like main search strategy, indicating a significant decline in their memory ability. They did not learn to find the platform or remember its location. The rats in the TEAT group showed a trend-based search strategy. The trajectory density was highest in the quadrant where the original platform was located, as well as in the adjacent quadrants. This indicates a memory improvement compared to the model group.
Figure 8B and Figure 8C show the results of the duration of stay in the quadrant of the original platform and the number of times the rats crossed the platform. The model group rats exhibited a significant reduction in their stay time in the original platform quadrant and the number of times they crossed the platform compared to the control group (p &#60;0.01). Compared to the model group, the TEAT group rats exhibited a significant increase in their stay time in the original platform quadrant and the number of times they crossed the platform (p &#60;0.01). These results suggest that TEAT can improve spatial learning and memory impairment in rats with AD-like pathology.
TEAT ameliorates hippocampal aging in rats (Figure 9). Compared to the control group, rats in the model group exhibited severe pathological changes, including a significant reduction in the number of pyramidal cells and their irregular arrangement. In addition, nuclear condensation, neuronal degeneration, and other abnormalities were observed. However, following TEAT treatment, the number of hippocampal pyramidal cells in rats increased and were more organized. Although some nuclei exhibited condensation, the overall cell morphology appeared more normal. Cells were more densely distributed and ordered, cytoplasmic staining was more consistent, and the edema surrounding the cells was significantly reduced. Notably, normal pyramidal cells were observed.

Consensus Brain-derived Protein, Extraction Protocol for the Study of Human and Murine Brain Proteome Using Both 2D-DIGE and Mini 2DE Immunoblotting

Two-dimensional gel electrophoresis (2DE) is a powerful tool to uncover proteome modifications potentially related to different physiological or pathological conditions. Basically, this technique is based on the separation of proteins according to their isoelectric point in a first step, and secondly according to their molecular weights by SDS polyacrylamide gel electrophoresis (SDS-PAGE). In this report an optimized sample preparation protocol for little amount of human post-mortem and mouse brain tissue is described. This method enables to perform both two-dimensional fluorescence difference gel electrophoresis (2D-DIGE) and mini 2DE immunoblotting. The combination of these approaches allows one to not only find new proteins and/or protein modifications in their expression thanks to its compatibility with mass spectrometry detection, but also a new insight into markers validation. Thus, mini-2DE coupled to western blotting permits to identify and validate post-translational modifications, proteins catabolism and provides a qualitative comparison among different conditions and/or treatments. Herein, we provide a method to study components of protein aggregates found in AD and Lewy body dementia such as the amyloid-beta peptide and the alpha-synuclein. Our method can thus be adapted for the analysis of the proteome and insoluble proteins extract from human brain tissue and mice models too. In parallel, it may provide useful information for the study of molecular and cellular pathways involved in neurodegenerative diseases as well as potential novel biomarkers and therapeutic targets.

A common protein extraction protocol using urea/thiourea/SDS buffer for human and mice brain tissue allows indentification of proteins by 2D-DIGE and their subsequent characterization by mini 2DE immunoblotting. This method enables one to obtain more reproducible and reliable results from human biopsies and experimental models.

Cognitive Improvement in Chronic Hypoxia Mice with Acupuncture

Acupuncture Treatment in a Mouse Model of Chronic Hypoxia-Induced Cognitive Dysfunction

The treatment of central nervous disorders has consistently posed significant challenges to the medical field. Acupuncture, a non-pharmacological practice rooted in traditional Chinese medicine, entails the insertion of fine needles into precise points on the body and is commonly employed for the management of diverse conditions. Recently, acupuncture has emerged as a promising therapeutic intervention for a range of neurological diseases, including anxiety and respiratory disorders. However, the potential of acupuncture in treating cognitive dysfunction induced by chronic hypoxia has not yet been explored. This paper presents a comprehensive protocol for establishing a mouse model of chronic hypoxia-induced cognitive impairment, administering mild anesthesia, performing acupuncture treatment, and assessing behavioral changes and memory abilities using open field tests and water mazes. The step-by-step protocol provides detailed instructions on accurately locating and positioning acupoints and needles for cognitive improvement. By employing this protocol, researchers can conduct systematic studies to thoroughly evaluate the therapeutic potential of acupuncture for cognitive dysfunction.

Assessment of Dendritic Arborization in the Dentate Gyrus of the Hippocampal Region in Mice

Dendritic arborization has been shown to be a reliable marker for examination of structural and functional integrity of neurons. Indeed, the complexity and extent of dendritic arborization correlates well with the synaptic plasticity in these cells. A reliable method for assessment of dendritic arborization is needed to characterize the deleterious effects of neurological disorders on these structures and to determine the effects of therapeutic interventions. However, quantification of these structures has proven to be a formidable task given their complex and dynamic nature. Fortunately, sophisticated imaging techniques can be paired with conventional staining methods to assess the state of dendritic arborization, providing a more reliable and expeditious means of assessment. Below is an example of how these imaging techniques were paired with staining methods to characterize the dendritic arborization in wild type mice. These complementary imaging methods can be used to qualitatively and quantitatively assess dendritic arborization that span a rather wide area within the hippocampal region.

We describe two methods for visualization and quantification of dendritic arborization in the hippocampus of mouse models: real-time and extended depth of field imaging. While the former method allows sophisticated topographical tracing and quantification of the extent of branching, the latter allows speedy visualization of the dendritic tree.

Acupoint Needle-Embedding Combined with Ironing Therapy for Postoperative Pain After Anal Surgery

Acupoint needle-embedding combined with ironing therapy is a non-drug treatment method to release postoperative pain after anal surgery. The practice is guided by traditional Chinese medicine (TCM) syndrome differentiation theory and employs acupoint stimulation and heat to alleviate pain. Although prior research has shown that these are dependable methods for pain relief, the combined effect of the two techniques has not been described. In our research, we found that compared to using diclofenac sodium enteric-coated capsules alone, adding acupoint needle-embedding combined with ironing therapy was more effective for reducing pain levels at different stages after hemorrhoid surgery. Although this technique is efficient and commonly used in clinics, due to its invasive practice, acupoint needle embedding still carries risks relating to hospital-acquired infections and broken needles. Ironing therapy, on the other hand, can result in burns and connective tissue injuries. Therefore, there is an urgent need to develop a standardized protocol for medical staff. Our protocol refines the traditional techniques and provides detailed instructions on patient preparation, operation techniques, and postoperative care to ensure the therapy is carried out safely and efficiently. By standardizing this therapy, this technique is expected to become an important complementary therapy for postoperative pain relief&#160;in hemorrhoids, which will significantly improve patients &#39;life quality after anal surgery.

The high incidence of pain after anal surgery is due to the physiological structure and pathological status of the anus. At present, the use of painkillers cannot provide satisfactory pain relief, which makes complementary therapy important. This paper proposes acupoint needle-embedding combined with ironing therapy to relieve postoperative pain.

Scalp Acupuncture Synchronizing Dual Task Gait for Enhancing Prefrontal Cortex Response

Studies have shown that motor-cognitive dual task can greatly improve motor/cognitive function. However, the therapeutic effect of motor-cognitive dual task is still limited. How to improve dual-task performance is the key to solving this problem. Scalp acupuncture is a non-drug intervention method of traditional Chinese medicine to treat brain-derived diseases by acupuncturing the corresponding projection area of cerebral cortex function on the scalp. Studies have shown that scalp acupuncture helps improve neuronal damage and cognitive dysfunction and plays a neuroprotective function in central nervous system diseases. However, no relevant studies have discussed the synergistic gain effect of motor-cognitive dual task and scalp acupuncture. Therefore, this protocol aims to demonstrate the standardized operation of scalp acupuncture synchronizing motor-cognitive dual task and motor-cognitive dual task and compares the differences between these two tasks in healthy subjects through a randomized cross-over trial. This protocol initially revealed the possible influence mechanism of scalp acupuncture synchronizing motor-cognitive dual task on cognitive performance, gait control, and cortical brain function, which can provide new ideas and a theoretical basis for clinical exploration of new and effective non-drug treatment of integrated Chinese and Western medicine.

This protocol demonstrates the standardized procedure of scalp acupuncture synchronizing motor-cognitive dual task and motor-cognitive dual task. This can provide an important reference for the clinical exploration of the new and effective non-drug treatment of integrated Chinese and Western medicine.

Acupuncture Stimulation of Ears to Alleviate Sleeping Disorders in COPD Patients

Auricular Acupuncture as a Traditional Chinese Medicine Therapy for Chronic Obstructive Pulmonary Disease Combined with Sleep Disorders

Chronic obstructive pulmonary disease (COPD) is a clinical syndrome characterized by persistent and irreversible airflow limitation and chronic respiratory symptoms. It has a wide spectrum of complications, and sleep disorders, as part of it, are common in severe cases, especially in elderly patients. Long-term lack of sleep may lead to the aggravation of the original disease, reducing patients' quality of life. Benzodiazepines are mainly used for symptomatic treatment of COPD combined with sleep disorders. However, such drugs have the side effect of respiratory central inhibition and could probably aggravate hypoxia symptoms. Auricular acupuncture is a special method of treating physical and psychosomatic dysfunctions by stimulating specific points in the ear. This article explains the specific methods of clinical operation of auricular acupuncture in detail, including assessment of patient eligibility, medical devices used, acupuncture points, course of treatment, post-treatment care, responses to emergencies, etc. The Pittsburgh sleep quality index (PSQI) and chronic obstructive pulmonary disease assessment scale (CAT) were used as the observational index of this method. So far, clinical reports have proved that auricular acupuncture has a definite curative effect in the treatment of COPD combined with sleep disorders, and its advantages of simple operation, few adverse reactions are worthy of further study and promotion, which provide a reference for the clinical treatment of such diseases.

Evaluating Acupoint Catgut Embedding Therapy for Allergic Rhinitis Management

Acupoint Catgut Embedding Therapy in Traditional Chinese Medicine for Managing Allergic Rhinitis

Acupuncture Point Embedding Therapy is a comprehensive treatment method that combines modern biomaterials with acupuncture techniques. Acupoint catgut embedding (ACE) not only avoids the adverse reactions associated with Western medicine but also incorporates the benefits of traditional acupuncture, extending the duration of its therapeutic effects. Allergic rhinitis (AR) is a condition known for its challenging treatment and tendency to persist. This randomized controlled trial included 128 AR patients to evaluate the effectiveness of ACE for AR management. Data were collected at baseline, four weeks after treatment, and eight weeks after treatment. Baseline analysis was performed, and the visual analog scale (VAS) was used as a clinical observation index for this method. The rhinoconjunctivitis quality of life questionnaire (RQLQ) served as a quality of life index. Specific IgE (sIgE), IL-4, IL-10, and IL-12 were used as laboratory observation indices. The results of the experiment validate the clinical effectiveness of ACE in treating AR. Although this technique is efficient and commonly used in clinics, its invasive nature poses risks of hospital-acquired infections. Based on this experiment, this protocol refines traditional techniques, providing detailed instructions on patient preparation, operation techniques, and postoperative care to ensure the safe and effective administration of therapy. By standardizing this therapy, ACE is anticipated to become an important non-drug treatment option for alleviating symptoms in AR patients, thereby significantly enhancing their quality of life.

This protocol details the procedure for acupoint burrowing and demonstrates its effectiveness in treating allergic rhinitis.

An Acupoint Catgut-embedding Therapy for Treating Obesity

Obesity is a chronic and complex disease caused by excessive fat deposition, which can lead to multiple complications. It affects individuals of all ages and backgrounds, contributing to a growing public health crisis worldwide. In modern medicine, the available treatments for obesity include drugs, behavioral modifications, and surgical procedures. However, their efficacy is often unsatisfactory and may be accompanied by various side effects. In contrast, Traditional Chinese Medicine offers a wide range of treatment options, including herbal tonics, acupuncture, tuina, acupoint catgut-embedding therapy, and more. Among these, acupoint catgut-embedding therapy has emerged as a popular choice for weight management due to its effectiveness, convenience, affordability, and minimal adverse effects. It involves the insertion of absorbable sutures into acupoints, stimulating the body's natural healing processes and enhancing metabolic function. The gradual absorption of the sutures over time provides a sustained therapeutic effect, allowing for prolonged benefits without the need for continuous treatment sessions. Whether used alone or in conjunction with other therapies, acupoint catgut-embedding therapy exemplifies the benefits of integrative medicine and its potential to empower individuals on their journey toward a healthier lifestyle. Aiming to visualize this ethnic medicine theory and promote its effective inheritance, we detail the acupoint catgut-embedding therapy method for weight loss, covering acupuncture points selection, materials, procedures, and precautions.

Here, we propose a specialized Chinese medicine treatment protocol to manage obesity. This treatment achieves weight loss by implanting absorbable surgical sutures into specific acupuncture points.
