Operation Procedure and Precautions of Thread-Embedding Acupuncture Therapy in Alzheimer

Summary

This study presents a protocol for thread-embedding acupuncture therapy in Alzheimer's disease-like rats.

Abstract

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'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's disease. Consequently, our research group has designated these manifestations as Alzheimer'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'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' 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's disease. This study suggests that TEAT may improve learning and memory in rats with Alzheimer's disease-like symptoms, indicating a potentially promising new treatment approach for this neurodegenerative condition.

Introduction

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, d....

Protocol

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 ± 1 °C and 40%-50% humidity, with free access to food and water. Following a one-week acclimatizati.......

Discussion

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, transmissi.......
