[Professor WANG Yin's academic thoughts and clinical application of acupuncture for spleen-sto-mach care].

Professor WANG Yin's academic thoughts and clinical application for difficult and miscellaneous di-seases, especially acupuncture for spleen-stomach care, are introduced. Based on TCM basic theory and "ten needles for elderly" by WANG Yueting, Professor WANG Yin proposes the acupuncture for spleen-stomach care. In this method, three-element acupoint selection is applied; the conception vessel, spleen meridian of foot taiyin and stomach meridian of foot yangming were selected. The deep and penetration acupuncture with 0.4 mm×100 mm elongated needles is used at Zhongwan (CV 12), Qihai (CV 6) and Zigong (EX-CA 1), and the mild reinforcing-reducing method is used at remaining acupoints. According to the severity of diseases, fire acupuncture combined with blood-letting cupping is applied at Tianshu (ST 25), Xuehai (SP 10) and Yinlingquan (SP 9); gene-rally, two acupoints are selected and 1 to 3 mL blood-letting is appropriate. The modification based on this me-thod can be applied for various difficult and miscellaneous diseases, leading to superior efficacy.

[Rheumatoid arthritis treated with acupoint application of huiyao tongluo dingtong san:a rando-mized controlled trial].

OBJECTIVE: To observe the clinical efficacy differences on rheumatoid arthritis treated with acupoint application of huiyao tongluo dingtong san (preparation of Hui medicine), tender point herbal application and leflunomide. METHODS: Ninety-six patients were randomized into an acupoint herbal application group, a tender point herbal application group and a leflunomide group, 32 cases in each one. In the acupoint herbal application group, huiyao tongluo dingtong san paste was used at Dazhui (GV 14), Mingmen (GV 4), Zusanli (ST 36) and the local points on the yang meridians around the knee joint. In the tender point herbal application group, the self-prepared Hui medicine was used at tender points, 4 to 6 h each time, at the interval of 7 days. In the leflunomide group, leflunomide was applied for oral administration, 50 mg on each of the first 3 days, once a day; 20 mg each time 3 days later, once a day. The treatment for 1 month made one session in the three groups, and continuous three sessions of treatment were required. The clinical symptoms, laboratory indices such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF) and the total score of symptoms were observed before and after treatment in the patients of three groups. The efficacy was evaluated in the 3 groups. RESULTS: The total effective rate was 87.5% (28/32) in the acupoint herbal application group and was 90.6% (29/32) in the leflunomide group, better than 68.8% (22/32) in the tender point herbal application group (both P<0.05). After treatment, the clinical symptoms, laboratory indices and the total score of symptoms were all improved as compared with those before treatment in the three groups (all P<0.05). Among the three groups, the results of pain, swelling, tenderness and the total score of symptoms as well as ESR and RF in the acupoint herbal application group and the leflunomide group were all better than those in the tender point herbal application group (P<0.05, P<0.01). Blister and pruritus occurred in 2 cases in each of the acupoint herbal application group and the tender point herbal application group. Nausea and poor appetites in 2 cases, dizziness and lassitude in 1 case and skin rashes in 1 case occurred in the leflunomide group. CONCLUSIONS: The improvements in the symptoms of rheumatoid arthritis and laboratory indices in the acupoint herbal application of huiyao tongluo dingtong san are better than those in the treatment with tender point herbal application. The efficacy of it is similar to that of leflunomide, without adverse reactions such as nausea, poor appetite, dizziness and lassitude.

Green tea drinking habits and gastric cancer in southwest China.

AIM: The purpose of this study was to investigate relationships between green tea consumption and gastric cancer development. METHODS: A population-based case-control study including 200 cases and 200 controls was conducted in the southwest area of China from May 2010 to February 2011. A self-designed questionnaire was used to collect data on factors influencing gastric cancer development, including tea drinking, conditional logistic regression being used to calculate odds ratios (ORs) and corresponding 95% confidence intervals (95% CIs). RESULTS: Cases with higher economic status had a reduced risk of gastric cancer, while those with cancer family history, drinking and smoking showed increased risk. Hot and very hot tea temperature was significantly related to high risk of gastric cancer with ORs (95%Cl) of 1.82 (1.03-3.52) and 3.07 (1.78-7.36), respectively. Further analysis indicated elevated risk of gastric cancer in former drinkers, former smokers and current drinkers when the measured tea temperature was hot. CONCLUSION: Drinking tea at high temperature increases the gastric cancer risk, especially in drinkers and smokers.
