[Therapeutic effects on rheumatoid arthritis treated with shu-deep needling and bloodletting techniques].

OBJECTIVE: To observe the difference in the therapeutic effects on rheumatoid arthritis (RA) between the combined shu-deep needling and bloodletting technique and the regular needling technique. METHODS: A total of 70 patients were randomized into an observation group (35 cases) and a control group (35 cases, 4 cases dropped-out). Dazhui (GV 14), Shenzhu (GV 12), Zhiyang (GV 9), Jinsuo (GV 8), Ganshu (BL 18), Shenshu (BL 23), Zhibian (BL 54), Weizhong (BL 40), Taixi (KI 3) and Tianzong (SI 11), etc. were selected in the two groups. Additionally, in the observation group the shu-deep needling technique was adopted at Tianzong (SI 11) and Zhibian (BL 54), the bloodletting technique at the local swollen area and the even-needling technique at the rest acupoints. In the control group, the even-needling technique was applied to all of the acupoints. Acupuncture treatment was given once every two days, 3 times a week and for 12 weeks totally. The numbers of tender points at the knee joint, the numbers of swollen sites at the knee joint, the visual analogue scale (VAS) score and the American health assessment questionnaire (HAQ) score were observed in the two groups before and after treatment, as well as the changes in erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). The American College of Rheumatology (ACR) criteria was adopted to evaluate the therapeutic effects of the two groups. RESULTS: After treatment, the numbers of tender points, the numbers of swollen sites, VAS score and HAQ score were all improved as compared with those before treatment in the two groups (all P<0.01), and the results in the observation group were better than those in the control group (all P<0.05). After treatment, ESR and CRP levels were all reduced as compared with those before treatment in the two groups (all P<0.01), but there was no significant differences between the two groups (both P>0.05). The standard-reaching rates of ACR 20 and ACR 50 in the observation group were 94.3% (33/35) and 31.4% (11/35) respectively, which were better than 67.7% (21/31) and 6.5% (2/31) in the control group (P<0.01, P<0.05). CONCLUSION: The acupuncture with the shu-deep and bloodletting techniques and the acupuncture with regular needling technique are all effective on RA. The therapeutic effects of the acupuncture treatment with the shu-deep and bloodletting techniques are better than that with regular needling technique.

[Protective Effects of Acupuncture Intervention Against Damage of Intestinal Mucosal Barrier Induced by 5-Fluorouracil in Rats].

OBJECTIVE: To observe the effect of acupuncture intervention on the diarrhea, mucosal thickness of the small intestine, plasma endotoxin (ET) and D-lactic acid (D-LA) contents, and diamine oxidase (DAO) activity in 5-Fluorouracil (5-Fu) induced intestinal mucosal damage rats, in order to provide an experimental basis for acupuncture therapy in improving chemotherapy-induced intestinal mucosa injury. METHODS: Thirty female SD rats were randomly divided into control group, model group and acupuncture group (n = 10 in each group). The intestinal mucosal damage model was established by intraperitoneal injection of 5-Fu (50 mg/kg, for six consecutive days). Acupuncture stimulation was applied to bilateral "Tianshu" (ST 25) and "Zusanli" (ST 36) once a day for six consecutive days. The changes of body weight and diarrhea score (0-3 points, according to Kurita's methods) as well as mucosal thickness of the small intestine were determined. The plasma ET and D-LA contents, and DAO activity were measured by ELISA. RESULTS: On the sixth day, the body weight was significantly higher in the acupuncture group than in the model group (P<0.05). After intraperitoneal injection of 5-Fu, both the incidence rate and average score of diarrhea reached the peak on the sixth day in the model and acupuncture groups, and were significantly lower in the acupuncture group than in the model group (P<0.01). On the seventh day, the mucosal thickness of small intestine was significantly lower in the model group than in the control group (P<0.05), but had no remarkable changes after acupuncture intervention( P>0.05). The contents of plasma ET and D-LA and DAO activity level were significantly higher in the model group than in the control group, and markedly decreased in the acupuncture group than in the model group (P<0.01). CONCLUSION: Acupuncture intervention can lower the incidence rate and average score of diarrhea and down-regulate the increased plasma ET and D-LA contents and DAO activity levels in 5-Fu induced intestinal mucosal damage rats, suggesting a somewhat protective effect of acupuncture against chemotherapy induced damage of the intestinal mucosal barrier.
