OBJECTIVES: To observe the effects on the glucose-lipid metabolism and the expression of zinc-α2-glycoprotein (ZAG) and glucose transporter 4 (GLUT4) in the femoral quadriceps and adipose tissue after electroacupuncture (EA) at "Pishu" (BL 20), "Weiwanxiashu" (EX-B 3), "Zusanli" (ST 36) and "Sanyinjiao" (SP 6) in the rats with diabetes mellitus type 2 (T2DM), so as to explore the effect mechanism of EA in treatment of T2DM. METHODS: Twelve ZDF male rats were fed with high-sugar and high-fat fodder, Purina #5008 for 4 weeks to induce T2DM model. After successfully modeled, the rats were randomly divided into a model group and an EA group, with 6 rats in each one. Additionally, 6 ZL male rats of the same months age were collected as the blank group. The rats in the EA group were treated with EA at bilateral "Pishu" (BL 20), "Weiwanxiashu" (EX-B 3), "Zusanli" (ST 36) and "Sanyinjiao" (SP 6), with continuous wave, 15 Hz in frequency, and 2 mA in intensity. The electric stimulation lasted 20 min each time. EA was delivered once daily, 6 times a week for 4 weeks. Separately, the levels of fasting blood glucose (FBG) was measured before modeling, before and after intervention, and the body mass of each rat was weighted before and after intervention. After intervention, the levels of the total cholesterol (TC), triacylglycerol (TG) and free fatty acid (FFA) in serum were detected using enzyme colorimetric method; and the levels of the serum insulin (INS) and ZAG were detected by ELISA. Besides, the insulin sensitivity index (HOMA-ISI) was calculated. With Western blot technique adopted, the protein expressions of ZAG and GLUT4 in the femoral quadriceps and adipose tissue were determined. RESULTS: After intervention, compared with the blank group, the levels of FBG and body mass, and the levels of serum TC, TG, FFA and INS increased (P<0.01), while HOMA-ISI decreased (P<0.01); the level of ZAG in the serum and the protein expressions of ZAG and GLUT4 in the femoral quadriceps and adipose tissue dropped (P<0.01) in the model group. In the EA group, compared with the model group, the levels of FBG and body mass, and the levels of serum TC, TG, FFA and INS were reduced (P<0.01), and HOMA-ISI increased (P<0.01); the level of ZAG in the serum and the protein expressions of ZAG and GLUT4 in the femoral quadriceps and adipose tissue increased (P<0.01, P<0.05). CONCLUSIONS: Electroacupuncture can effectively regulate glucose-lipid metabolism, improve insulin resistance and sensitivity in the rats with T2DM, which is associated with the modulation of ZAG and GLUT4 expression in the skeletal muscle and adipose tissue.

[Clinical random trial of thumbtack needling therapy for analgesia after cesarean section].

OBJECTIVE: To observe the analgesic effect of thumbtack needling therapy and the quality of life in puerpera underwent cesarean section. METHODS: One hundred and thirty-five puerpera underwent cesarean section were randomly divided into a medication group, a sham-thumbtack needling group and a thumbtack needling group, 45 cases in each group. In the medication group, the patient control analgesia (PCA) was given. In the thumbtack needling group, on the base of the regimen as the medication group, acupuncture with thumbtack needles was applied to lower abdominal point (Extra), Zusanli (ST36), Sanyinjiao (SP6), Geshu (BL17), Shenshu (BL23) and Dachangshu (BL25). The needles were retained for 48 hours. During the needle retaining, the sites with the needle embedded were pressed and kneaded for 3 times, 1 min each time, at the interval of 4 to 12 h. In the sham-thumbtack needling group, the sham-thumbtack needles were used; the acupoint selection, operation and treatment course were all the same as the thumbtack needling group. The visual analogue scale (VAS) scores of incision pain and ute-rine contraction pain, the incidence of postoperative adverse reactions, the amount of vaginal bleeding and milk amount in lactation were observed at each time point after the operation separately in each group. RESULTS: Compared with the medication group, the VAS score of incision pain was decreased 8, 12 and 24 h after operation (P<0.05), the VAS score of uterine contraction pain was decreased 8, 12, 24 and 48 h after operation (P<0.05), the lactation score was increased in 24 to 48 h after operation (P<0.05) in both the sham-thumbtack needling group and thumbtack needling group. Compared with the sham-thumbtack needling group, the VAS score of incision pain was decreased 8, 12 and 24 h after operation (P<0.05), the VAS score of uterine contraction pain was decreased 24 and 48 h after operation (P<0.05) in the thumbtack needling group. Compared with those from 2 to 24 h after operation, the vaginal bleeding amount was decreased and the lactation score increased from 24 to 48 h after operation (P<0.05) in all of the three groups. CONCLUSION: The conventional PCA combined with thumbtack needling therapy obtained better analgesic effects on incision dynamic pain and uterine contraction pain in patients after cesarean section as compared with either the simple PCA or the combined treatment with sham-thumbtack needling and medication, and both the thumbtack needling and the sham-thumbtack needling therapy can increase the milk amount of lactation from 24 to 48 h after operation.

[Randomized Controlled Clinical Trials for Acupuncture Treatment of Pneumoconiosis].

OBJECTIVE: To observe the clinical therapeutic effect of acupuncture therapy in improving pulmonary functions and clinical symptoms of pneumoconiosis patients. METHODS: A total of 120 pneumoconiosis patients were randomly divided into acupuncture group (n=59) and control group (n = 61). The patients of the control group were ordered to take Acetylcysteine capsule (200 mg/time, t.i.d.) for 12 consecutive weeks and the patients of the acupuncture group received both acupuncture (twice a week) and Acetylcysteine capsule for 12 consecutive weeks. The used acupoints were Baihui (GV 20), Tanzhong (CV 17), Zhongwan (CV 12), Qihai (CV 6), and bilateral Kongzui (LU 6), Taiyuan (LU 9), Yuji (LU 10), Zusanli (ST 36), Fenglong (ST 40), Sanyinjiao (SP 6), Feishu (BL 13), Xinshu (BL 15), Ganshu (BL 18), Pishu (BL 20), Shenshu (BL 23) and Geshu (BL 17) and stimulated by needle-twirling reducing or reinforcing techniques. The pulmonary functions including spirometric forced vital capacity(FVC) and forced expiratory volume in one second (FEV 1), FEV 1/FVC, and diffusion capacity for carbon monoxide (DLCO) were detected by using a Medgraphics Cardio 2 Combined VO 2/ECG Exercise System. The severity of cough and shortness of breath (SOB) was detected by Visual Analog Scale (VAS), and the patient's health status was assessed using Chronic Obstructive Pulmonary Disease Assessment Test (CAT score, 0-40 points). RESULTS: Compared with pretreatment in the same one group, FE1 level and FEV 1/FVC after 12 weeks' treatment were obviously increased in both the control and acupuncture groups (P<0.05), while the CAT scores at the 12th week, the cough and SOB scores at the 6th, 12th and 16th week after the treatment were decreased notably in both groups (P<0.05), and the cough and SOB scores of the acupuncture group were significantly lower than those of the control group (P<0.05). No significant changes were found in the FVC and DLCO levels in both groups (P>0.05). CONCLUSION: Acupuncture therapy can improve symptoms of cough, shortness of breath, as well as pulmonary functions in pneumoconiosis patients.

[Treatment of delayed complex malhealed jaw fractures in 32 patients.].

PURPOSE: Three methods were used to manage delayed complex malhealed jaw fractures in 32 patients. The indication for each method and final result was evaluated. METHODS: Three methods included conservative therapy, internal fixation and orthognathic surgery. In conservative therapy, intermaxillary fixation was obtained with dental arch splints. In internal fixation, ordinary operation was performed including open exposure of the fractured segments, anatomical reposition and rigid fixation with steel wire or titanium miniplates. In some patients, orthognathic surgery was carried out with intermaxillary ligation for 2 to 3 weeks postoperatively. RESULTS: All the wounds healed primarily without significant complications. The postoperative occlusion and appearance were satisfactory or fair. CONCLUSIONS: The selection of treatment methods should be based on the location, time, severity of the fracture and the patients' age, in order to achieve maximal recovery of mastication and appearance.
