佩罗尼氏病 （PD） 是一种慢性纤维化疾病，会导致畸形、弯曲、疼痛、性残疾，甚至导致心理困扰1。帕金森病可能代表一种异质性疾病，可遗传和环境驱动的表观遗传因素都有助于其发展和进展2. 
帕金森病报告的流行病学各不相同，由于对可用治疗方案的尴尬和误解，可能被低估，在不同种族和队列中为 0.4%-20.3% 2,3。帕金森病的治疗包括保守治疗或手术干预，具体取决于症状的严重程度和稳定性。保守治疗是活动期最常见的建议，而更具侵入性的治疗则保留在被动期4。最近一项随机对照试验评估了胶原酶溶组织梭菌 （CCH） + RestoreX牵引与手术 + RestoreX牵引在佩罗尼氏病管理中的疗效，表明这两种策略之间的结果相当5.
尽管牵引疗法和病灶内注射对许多患者有一定程度的改善，但手术干预仍然是这种疾病的最终解决方案，特别是对于那些有严重弯曲和沙漏或铰链畸形的患者1.目前，矫直术，如折叠术和牙菌斑切口或部分切除术和移植术，是矫正曲率或畸形的最可靠方法6。然而，报告的方法具有很高的感觉丧失率、勃起功能丧失或美容不满意 5,7,8。
电动研磨机通常用于神经外科和骨科，作为骨骼整形的有效工具。它在研磨硬组织（如骨骼）方面表现出很高的效率，同时对软组织造成的损害最小。这一特性使其在治疗硬斑块方面具有独特的优势。

microscopic electric rotary grinding of plaques combined with graft repair in the management of peyronie's disease

佩罗尼氏病 （PD） 的临床特征是局部纤维斑块的形成，主要在白膜上，尤其是在阴茎背侧区域。这些斑块是这种情况的标志性特征，导致受影响的个体弯曲、畸形和疼痛的勃起。尽管存在各种非手术治疗方案，但其总体效果有限。因此，手术干预已成为患有严重曲率畸形和相关勃起功能障碍患者的最终选择。我们的研究团队成功地采用了一种组合方法，包括显微镜下电动旋转研磨纤维斑块和使用阴道膜或牛心包作为移植材料来修复白膜膜的缺陷，以治疗帕金森病。这种方法在恢复形状方面一直产生非常令人满意的结果，具有出色的美容效果和显着提高的性满意度。

Surgical Management of Meatal Stenosis with Meatoplasty

Meatal stenosis is a common urologic complication after circumcision. Children present to their primary care physicians with complaints of deviated urinary stream, difficult-to-aim, painful urination, and urinary frequency. Clinical exam reveals a pinpoint meatus and if the child is asked to urinate, he will usually have an upward, thin, occasionally forceful urinary stream with incomplete bladder emptying. The mainstay of management is meatoplasty (reconstruction of the distal urethra /meatus). This educational video will demonstrate how this is performed.

High Throughput Sequential ELISA for Validation of Biomarkers of Acute Graft-Versus-Host Disease

Unbiased discovery proteomics strategies have the potential to identify large numbers of novel biomarkers that can improve diagnostic and prognostic testing in a clinical setting and may help guide therapeutic interventions. When large numbers of candidate proteins are identified, it may be difficult to validate candidate biomarkers in a timely and efficient fashion from patient plasma samples that are event-driven, of finite volume and irreplaceable, such as at the onset of acute graft-versus-host disease (GVHD), a potentially life-threatening complication of allogeneic hematopoietic stem cell transplantation (HSCT).
Here we describe the process of performing commercially available ELISAs for six validated GVHD proteins: IL-2R&alpha;5, TNFR16, HGF7, IL-88, elafin2, and REG3&alpha;3 (also known as PAP1) in a sequential fashion to minimize freeze-thaw cycles, thawed plasma time and plasma usage. For this procedure we perform the ELISAs in sequential order as determined by sample dilution factor as established in our laboratory using manufacturer ELISA kits and protocols with minor adjustments to facilitate optimal sequential ELISA performance. The resulting plasma biomarker concentrations can then be compiled and analyzed for significant findings within a patient cohort. While these biomarkers are currently for research purposes only, their incorporation into clinical care is currently being investigated in clinical trials.
This technique can be applied to perform ELISAs for multiple proteins/cytokines of interest on the same sample(s) provided the samples do not need to be mixed with other reagents. If ELISA kits do not come with pre-coated plates, 96-well half-well plates or 384-well plates can be used to further minimize use of samples/reagents.

High throughput validation of multiple candidate biomarkers can be performed by sequential ELISA in order to minimize freeze/thaw cycles and use of precious plasma samples. Here, we demonstrate how to sequentially perform ELISAs for six different validated plasma biomarkers1-3 of graft-versus-host disease (GVHD)4 on the same plasma sample.

Induction of Atherosclerotic Plaques Through Activation of Mineralocorticoid Receptors in Apolipoprotein E-deficient Mice

Atherosclerosis is due to a chronic inflammatory response affecting vascular endothelium and is promoted by several factors such as hypertension, dyslipidemia, and diabetes. To date, there is evidence to support a role for circulating aldosterone as a risk factor for the development of cardiovascular disease. Transgenic mouse models have been generated to study cellular and molecular processes leading to atherosclerosis. In this manuscript, we describe a protocol that takes advantage of continuous infusion of aldosterone in ApoE-/- mice and generates atherosclerotic plaques in the aortic root after 4 weeks of treatment. We, therefore, illustrate a method for quantification and characterization of atherosclerotic lesions at the aortic root level. The added value of aldosterone infusion is represented by the generation of atherosclerotic lesions rich in lipid and inflammatory cells after 4 weeks of treatment. We describe in detail the staining procedures to quantify lipid and macrophage content within the plaque. Notably, in this protocol, we perform heart tissue-embedding in OCT in order to preserve the antigenicity of cardiac tissue and facilitate detectability of antigens of interest. Analysis of the plaque phenotype represents a valid approach to study the pathophysiology of atherosclerosis development and to identify novel pharmacological targets for the development of anti-atherogenic drugs.

We describe a protocol to induce atherosclerosis in the aortic root of ApoE-/- mice fed with an atherogenic diet, through a continuous release of aldosterone. Methods to characterize plaque composition are also described.

Using a Chemical Biopsy for Graft Quality Assessment

Kidney transplantation is a life-saving treatment for a large number of people with end-stage renal dysfunction worldwide. The procedure is associated with an increased survival rate and greater quality of patient&#8217;s life when compared to conventional dialysis. Regrettably, transplantology suffers from a lack of reliable methods for organ quality assessment. Standard diagnostic techniques are limited to macroscopic appearance inspection or invasive tissue biopsy, which do not provide comprehensive information about the graft. The proposed protocol aims to introduce solid phase microextraction (SPME) as an ideal analytical method for comprehensive metabolomics and lipidomic analysis of all low molecular compounds present in kidneys allocated for transplantation. The small size of the SPME probe enables performance of a chemical biopsy, which enables extraction of metabolites directly from the organ without any tissue collection. The minimum invasiveness of the method permits execution of multiple analyses over time: directly after organ harvesting, during its preservation, and immediately after revascularization at the recipient&#8217;s body. It is hypothesized that the combination of this novel sampling method with a high-resolution mass spectrometer will allow for discrimination of a set of characteristic compounds that could serve as biological markers of graft quality and indicators of possible development of organ dysfunction.

The protocol presents utilization of the chemical biopsy approach followed by comprehensive metabolomic and lipidomic analysis for quality assessment of kidney grafts allocated for transplantation.

The Microscopic Transcanal Approach in Stapes Surgery Revisited

The microscopic transcanal (aka transmeatal) surgical approach was first described in the 60s, offering a minimally invasive means of reaching the external auditory canal, the middle ear, and epitympanon. Such an approach avoids a retroauricular or endaural skin incision; however, working through a narrow space needs angled microsurgical instruments and specific training in otologic surgery. The transcanal approach restricts the working space; however, it offers a binocular microscopic vision into the middle ear without extended skin incisions and thus, reducing post-operative pain and bleeding. In addition, this minimally invasive approach avoids scar tissue complications, hypoesthesia of the auricle, and potential protrusion of the pinna. Despite its numerous advantages, this method is still not routinely performed by otologic surgeons. Since this minimally invasive technique is more challenging, there is a need for extensive training in order for it to be widely adopted by otologic surgeons. This article provides step-by-step surgical instructions for stapes surgery and reports possible indications, pitfalls, and limitations using this microscopic transcanal technique.

This article describes the microscopic transcanal technique for stapes surgery, providing step-by-step surgical instructions for familiarizing surgeons with this approach.

Establishment and Evaluation of a Porcine Vein Graft Disease Model

Venous graft disease (VGD) is the leading cause of coronary artery bypass graft (CABG) failure. Large animal models of CABG-VGD are needed for the investigation of disease mechanisms and the development of therapeutic strategies. 
To perform the surgery, we enter the cardiac chamber through the third intercostal space and carefully dissect the internal mammary vein and immerse it in normal saline. The right main coronary artery is then treated for ischemia. The target vessel is incised, a shunt plug is placed, and the distal end of the graft vein is anastomosed. The ascending aorta is partially blocked, and the proximal end of the graft vein is anastomosed after perforation. The graft vein is checked for patency, and the proximal right coronary artery is ligated. 
CABG surgery is performed in minipigs to harvest the left internal mammary vein for its use as a vascular graft. Serum biochemical tests are used to evaluate the physiological status of the animals after surgery. Ultrasound examination shows that the proximal, middle, and distal end of the graft vessel are unobstructed. In the surgical model, turbulent blood flow in the graft is observed upon histological examination after the CABG surgery, and venous graft stenosis associated with intimal hyperplasia is observed in the graft. The study here provides detailed surgical procedures for the establishment of a repeatable CABG-induced VGD model.

In this protocol, novel pig vein bypass grafting was performed through a small incision in the left chest wall without cardiopulmonary bypass. A postoperative pathology study was done, which showed intimal thickening.

Application of Laparoscopic Hepatectomy Combined with Intraoperative Microwave Ablation in Colorectal Cancer Liver Metastasis

Laparoscopic hepatectomy is a common treatment for colorectal cancer liver metastasis. Previously, a sufficient number of functional liver masses had to be maintained during laparoscopic hepatectomy, with a residual liver volume of &gt;40% in cirrhotic patients and &gt;30% in non-cirrhotic patients. The high incidence of complications such as bleeding, bile leakage, or liver failure due to the exposure and difficulty of the resection of specific liver segments such as S2 and S7 reduces the success rate of liver resection. At present, microwave ablation is mainly applied in the treatment of liver metastasis using a percutaneous approach, which makes it difficult to identify hidden parts or small lesions. For some liver segments, the percutaneous puncture of liver segment 7 (S7) is likely to pass through the thoracic cavity, and the percutaneous puncture of liver segment 2 (S2) adjacent to the diaphragm is likely to injure the diaphragm and heart; these issues restrict the application of percutaneous ablation in colorectal cancer liver metastasis. Considering multiple lesions, laparoscopic microwave ablation combined with hepatectomy was performed in this study. The location of the lesions was determined by contrast-enhanced ultrasound under laparoscopy, and small lesions that were difficult to detect before the operation were identified. For the scattered lesions, which had diameters less than 3 cm and were difficult to resect, ablation was adopted to substitute hepatectomy. This technique helped to more explicitly locate the tumors, simplified the operation procedures, reduced the risk of complications such as bleeding and bile leakage, shortened the operation time, accelerated the postoperative recovery, significantly improved the success rate of operation, and enhanced the clinical prognosis of colorectal cancer liver metastasis by surgical resection.

This protocol describes the laparoscopic resection of colorectal cancer liver metastases combined with ultrasound-guided microwave ablation. This technique can safely, effectively, and accurately treat refractory liver metastases &lt;3 cm, reduce postoperative complications, and accelerate the postoperative rehabilitation of patients.

Microscopic Cyst Resection for the Treatment of Patients Diagnosed with Epididymal Cyst

Epididymal cysts mostly occur in men aged 20-40 years old. Previous reports have covered concerns about postoperative complexes, including postoperative asoedema, hematoma, sustaining pain, and seminal tract obstruction in patients who have undertaken nonmicroscopic epididymal cyst resection or epididymal resection. Nonmicroscopic epididymal cyst surgery is suggested for patients with childbirth plans as a precaution. The treatment of male epididymal cysts via microtechnology is obviously a beneficial option; we took the lead in carrying out microscopic epididymal exploration and cyst resection surgery in China. From September 2017 to April 2021, 41 young and middle-aged male patients diagnosed with epididymal cysts underwent microtechnology treatment in a program titled &#34;microscopic epididymal exploration and cystectomy&#34;. The postoperative follow-up lasted for 3-50 months. The results confirmed that, as microscopic manipulation largely improved visualization of the subtle tissue structures of the epididymis, the cyst could be clearly dissected apart and completely removed intact under the microscope. Bleeding during the operation was significantly reduced (2-3 mL) and wound drainage was not required. According to follow-up data, microscopic treatment significantly reduced the incidence of postoperative scrotal hematoma, edema, and long-term postoperative pain, thereby promising a higher surgical success rate as well as recurrence prevention. Besides, preliminary experience and reflection suggest that microscopic epididymal exploration and cystectomy provide efficient preservation of the epididymal patency through refined treatment, while a better prognosis can be achieved. We recommend that surgery be carried out before the epididymal cyst develops to 0.8 cm in diameter, for fear that a larger epididymal cyst (&#62;0.9 cm in diameter) could cause the complete destruction of all tubules of the ipsilateral epididymis - a more severe case with damage to the testicular output network.

Here, we present a protocol to treat patients diagnosed with an epididymal cyst using microscopic cyst resection. Based on microscopic manipulation, a largely improved visualization of the subtle tissue structures of the epididymis was obtained, so the cyst could be clearly dissected apart and completely removed intact.

Management of the Uncinate Process in No-Touch Laparoscopic Pancreaticoduodenectomy

Laparoscopic pancreatoduodenectomy (LPD) is a demanding abdominal operation that necessitates meticulous surgical skills and teamwork. The management of the pancreatic uncinate process is one of the most important and difficult processes in LPD because of its deep anatomical location and difficult exposure. Complete resection of the uncinate process and mesopancreas has become the cornerstone of LPD. In particular, it is even more difficult to avoid positive surgical margins and incomplete lymph node dissection when the tumor is located in the uncinate process. No-touch LPD, which is an ideal oncological operation process fitting the "tumor-free" principle, has been reported by our group previously. This article introduces the management of the uncinate process in no-touch LPD. Based on the multi-angle arterial approach, in this protocol, the median-anterior and left-posterior approaches to the SMA are used to correctly deal with the important vascular structure, the inferior pancreaticoduodenal artery (IPDA), in order to ensure the safe and complete excision of the uncinate process and mesopancreas. For the achievement of the no-touch isolation technique in LPD, the pancreatic head and the blood supply to the duodenal region must be severed at the very early stage of the operation; after that, the tumor can be isolated intact, resection can be performed in situ, and finally, the tissue can be removed en bloc. This paper aims to show the distinctive ways to manage the uncinate process in no-touch LPD and investigate the viability and safety of this approach. Moreover, the technique may increase the R0 resection rate.

Complete resection of the uncinate process and mesopancreas is one of the most important and difficult processes in laparoscopic pancreatoduodenectomy (LPD). This article presents a method for managing the uncinate process in no-touch LPD using the median-anterior and left-posterior approaches to the superior mesenteric artery (SMA).

Effects of Mindfulness Training Combined with Tai Chi in Patients with Diabetic Peripheral Neuropathy

Diabetic peripheral neuropathy (DPN) is one of the most prevalent chronic complications of diabetes. One of its crucial therapy approaches is mind-body exercise. Recently, various exercise modalities, including stepping, resistance, aerobics, balance, and whole-body vibration, were investigated to construct the most suitable form of exercise for patients with DPN. The purpose of this study is to describe a standard protocol for mindfulness training combined with Tai Chi. The convenience sampling method was used to select 90 patients with DPN who met the inclusion and exclusion criteria from three communities. The three communities were randomly divided into the control group (CG), the Tai Chi group (TCG), and the mindfulness training combined with the Tai Chi group (MTCG). The CG was given routine health education guidance once a month, a total of three times. Based on the CG, the TCG practiced Tai Chi three times; the MTCG received mindfulness training combined with Tai Chi exercise a week for a total of 12 weeks. Before the intervention and 12 weeks after the intervention, the clinical symptoms, neurological function, attention awareness level, pain, and quality of life of the subjects were evaluated by Toronto Clinical Scoring System (TCSS), Mindful Attention Awareness Scale (MAAS), Visual analog scale (VAS), Diabetes Specificity Quality of life Scale (DSQL) and tumor necrosis factor-&#945;. Overall, the addition of mindfulness training to Tai Chi effectively enhances the exercise effects of Tai Chi. Therefore, mindfulness training combined with Tai Chi is worthy of promotion and application.
