ABSTRACT
OBJECTIVES: To observe the effect of the acupuncture of myofascial trigger points (MTrPs) in the treatment of lower extremity varicose veins (LEVVs). METHODS: Overall, 260 patients with LEVVs participated in this study. LEVVs were selected based on diagnostic criteria of Clinical, Etiology, Anatomy, and Pathophysiology levels 2-5 and classified into six types on the basis of their anatomical positions. The MTrPs in the lower extremities were localized in accordance with the classification of LEVVs and treated by MTrPs acupuncture combined with self-massage and self-stretching. The interval between each treatment was 2 weeks to 1 month, depending on needling pain tolerance of each patient. An in-house evaluation was used to estimate the proportion of varicose veins in the lower limbs and their accompanying symptoms. The treatment effect was evaluated before each treatment and at 1-year follow-up. RESULTS: The mean evaluation score of LEVVs before the treatment course was 3.66 ± 1.19. After the course, this reduced to 1.18 ± 0.97, with the following response rates: 85% for excellent and good and 15% for medium. After 1-year follow-up, the mean evaluation score of all patients was 1.11 ± 0.92, with the following response rates: 87% for excellent and good, and 13% for medium. CONCLUSIONS: In some patients, MTrP acupuncture could cure LEVVs and its accompanying symptoms. These LEVVs are probably caused by fascia tension as a pre-pathology induced by the MTrPs.

OBJECTIVE: To explore the effect of electroacupunctureï¼EAï¼on the expression of muscle-specific ring finger protein 1ï¼MuRF1/Trim63ï¼ï¼F-box only protein 32ï¼Fbxo32ï¼ï¼myosin heavy chain-IIaï¼Myh2ï¼ï¼myosin heavy chain-IIbï¼Myh4ï¼and myosin heavy chain-Iï¼Myh7ï¼in diabetes rats. METHODS: Thirty-six male Wistar rats were equally randomized into control, model and EA groups. The diabetes model was established by intraperitoneal injection of 0.1% Streptozocin (STZ) solution (50 mg/kg). After that, EA (2 Hz, 1 mA) was applied to bilateral "Zusanli" (ST36), "Yinlingquan" (SP9) and "Shenshu" (BL23) for 10 min, once a day, 6 times a week for 2 weeks. The fasting blood glucose (FBG) and fasting serum insulin (FINS) contents were assayed by using ELISA, and the homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. The body weight, and wet weight of bilateral gastrocnemius muscles were measured. The cross-sectional area (CSA) of the gastrocnemius muscle was measured after H.E. stai-ning. The expression of MuRF1, Fbxo32, Myh2, Myh4 and Myh7 mRNAs in the gastrocnemius tissue was tested using quantitative real time-PCR. RESULTS: Compared with the control group, the FBG and HOMA-IR were significantly higher (P<0.05), and the FINS, body weight were significantly lower (P<0.05) after intravenous injection of STZ for 1, 2, 3, 4, 5 weeks respectively. Following EA treatment and compared with the model group, the FBG and HOMA-IR were significantly down-regulated (P<0.05), and the FINS and body weight were considerably increased (P<0.05). Following modeling and compared with the control group, the wet weight of gastrocnemius muscle, CSA, and expression levels of Myh2, Myh4 and Myh7 mRNAs were obviously decreased, and the expression of MuRF1 and Fbxo32 mRNA was obviously increased in the model group (P<0.05). After EA treatment, the gastrocnemius muscle wet weight, CSA, expression levels of Myh2, Myh4 and Myh7 mRNA were significantly up-regulated (P<0.05), and the expression levels of MuRF1 and Fbxo32 mRNA were markedly down-regulated in comparison with those of the model group (P<0.05). CONCLUSION: EA treatment can delay the atrophy of gastrocnemius muscle (skeletal muscle) in diabetes rats possibly by improving the degradation of myosin heavy chain via regulating the expression of muscular MuRF1, Fbxo32, Myh2, Myh4 and Myh7 mRNAs.
