BACKGROUND: Acupuncture has been confirmed to be effective in treating Parkinson disease both clinically and experimentally, but there is still lack of systematical and complete therapeutic principle and law to be followed in clinic.OBJECTIVE: To observe the influence on glutathione (GSH), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), malondialdehyde(MDA)and nitric oxide synthase (NOS) in corpus striatum of the damaged side in rat models of Parkinson disease by acupuncture at subthalamus.DESIGN: A randomized controlled animal experiment.SETTING: The Second Affiliated Hospital of Heilongjiang University of Traditional Chinese Medicine.MATERIALS: The experiment was performed in the Experimental Animal Center of Heilongjiang University of Traditional Chinese Medicine from January to June in 2003. Eighteen healthy adult Wistar rats of pure breed were randomly divided into 3 groups with 6 rats in each:electroacupuncture group, model group and normal saline group.METHODS: ① Model group: The rats were made into models of Parkinson disease with damaged corpus striatum by injecting 6-hydroxydopamine (6-OHDA, 12 μg), which was dissolved in 5 μL normal saline containing 2 g/L ascorbic acid, slowly into caudal putamen. without intervention. ②Normal saline group: 6-OHDA was replaced by normal saline of the same dosage, and other treatments were the same as those in the model group. ③ Electroacupuncture group: The model preperation was the same as that in the model group. The needles were embedded in subthalamus at 6 weeks postoperatively, and then electroacupuncture (in frequency of 100 Hz, and the intensity about 1 mA) was given one week later for 2 weeks, once a day,15 minutes for each time.MAIN OUTCOME MEASURES: All the rats were killed by cutting heads to remove brain under anesthesia at 2 weeks after electroacupuncture, and the activities of GSH, GSH-Px, SOD and NOS and the concentration of MDA were detected with chromatometry.RESULTS: All the 18 rats were involved in the analysis of results. ① MDA concentration was higher in the model group and electroacupuncture group than in the normal saline group [(5.53±0.71),(4.10±0.27), (5.53±0.71) μmol/L, P ＜ 0.01], but lower in the electroacupuncture group than in the model group (P ＜ 0.05). ② The activities of GSH and GSH-Px were both lower model group and electroacupuncture group than in the normal saline group (P ＜ 0.01), but lower in the electroacupuncture group than in the model group (P ＜ 0.05).③ The activity of SOD was higher in the model group and electroacupuncture group than in the normal saline group [(113.36±2.17),(73.85±5.17), (42.34±1.83) μkat/g, P ＜ 0.01], but lower in the electroacupuncture group than in the model group (P ＜ 0.01).CONCLUSION: The anti-oxidation capability of the rat models of Parkinson disease has been recovered and the nerve injury has been reduced after acupuncture, indicating that it is available and effective to treat Parkinson disease by acupuncture at subthalamus.

Lateral epicondylitis is a common clinical disease with characteristics of lateral elbow pain, insidious onset and easy recurrence, which can cause forearm pain and decreased wrist strength, seriously affecting patients′ daily life and work. Although there are various treatment methods for lateral epicondylitis with different effects, standard treatments are still lacking nowadays. Platelet-rich plasma (PRP) has good effects on bone and tendon repair, and is now widely used in the treatment of lateral epicondylitis. However, there is a lack of a unified understanding of the technology and specifications of PRP in the treatment of lateral epicondylitis. Therefore, the Sports Medicine Branch of the Chinese Medical Association and Physical Medicine and Rehabilitation Branch of the Chinese Medical Association organized experts in the fields of sports medicine and rehabilitation medicine in China to formulate the "clinical expert consensus on platelet-rich plasma treatment for lateral epicondylitis (2022 version)", and proposed suggestions based on evidence-based medicine mainly from the concept, epidemiology and pathophysiology of lateral epicondylitis, symptoms, signs and imaging manifestations of lateral epicondylitis, PRP concept and application component requirements, quality control of PRP preparation technology, indications and contraindications of PRP in the treatment of lateral epicondylitis, PRP injection in the treatment of lateral epicondylitis, application of PRP in the operation of lateral epicondylitis, related problems after PRP treatment of lateral epicondylitis, evaluation of the results after PRP treatment of lateral epicondylitis, and health and economic evaluation of PRP treatment of lateral epicondylitis, so as to provide guidance for clinical diagnosis and treatment.
