OBJECTIVETo summarize laws of acupoint selection of prescriptions for treatment of cervicogenic headache by acupuncture in modern literature.

METHODSRandomized controlled trials (RCTs) involving acupuncture and moxibustion for treatment of cervicogenic headache were recruited from CBM (1978-2012), VIP (1989-2012), Wanfang Database (1998-2012), CNKI (1979-2012), PubMed (1966-2012), EMbase (1980-2012), and Cochrane Library (Volume 4, 2012). Hand recruitment was also auxiliarily used. The frequency and percentage of common acupoints, the distribution of acupoints along 14 meridians and across each part of the body, the application of specific acupoints, and features of using prescriptions for specific acupoints were statistically described.

RESULTSTotally 37 recruited papers included 42 acupoints and 159 times. Common acupoints covered Fengchi (GB20, 28 times), Jingjiaji (EX-B2, 21 times), Baihui (DU 20, 12 times), Tianzhu (BL9, 1 times), and Ashi point (11 times). Meridians along which acupoints were used mainly covered Foot-shaoyang Gallbladder Meridian, Foot-taiyang Bladder Meridian,and DU meridian. Acupoints were mainly needled from head, neck, and upper limbs. Eight confluence points and luo-connecting point were commonest used as specific acupoints. Acupuncture prescriptions were mostly composed of multiple acupoints. Filliform needle was mainly used in acupuncture methods, followed by electro-acupuncture needle.

CONCLUSIONSModern acupuncture treatment of cervicogenic headache focuses on local specific points and acupoints along meridians. Acupoints were mostly selected from head, neck, and upper limbs by syndrome typing of Chinese medicine.

Objective To explone the therapeutic effect and mechanism of Quyuhuatan decoction in treating type 2 diabetes mellitus combined with abnormal metabolism of lipid. Methods 85 cases of type 2 diabetes mellitus combined with abnormal metabolism of lipid were recruited into a control group and a treatment group randomly. The treatment group (45cases) was treated with Quyuhuatan decoction and subcutaneous insulin injection while the control group(40cases) was treated with subcutaneous insulin injection exclusively. Both groups received the treatment for for 8 weeks. The result of TC, TG, LDL-C, and HDT-C were observed before and after the treatment. Results The improvement of blood lipid in the treatment group was superior to that in the control group (t=0.011, P<0.05) . Conclusion Quyuhuatan decoction is effective in treating type 2 diabetes mellitus combined with abnormal metabolism of lipid. The mechanism might be related with its cutting off pathological paths of hyperlipidemia.

Purpose:To explore the role of terminal restric tion fragments (TRFs), telomerase activity and expression of human telomerase re verse transcriptase (hTERT) in colorectal carcinoma. Methods:The telomere length, telomerase activity and expression of hTERT were studied with Southern-blot, TRAP and immunohistochemistry, respe ctively. Results:TRFs in cancer tissue was much shorter than in the adja cent tissues and normal mucosa, and TRFs was decreased gradually along with the development in cancer stage.The expression of Telomerase in colorectal carcinoma tissue was significantly higher than that in other tissues (P

Objective:To find out whether the dentin formation of hypophosphatasia children is affec-ted;to study the biological difference of cultured human dental pulp cells from deciduous teeth between hypophosphatasia and normal healthy children.Methods: Anterior deciduous teeth were collected from hypophosphatasia(experiment group)and normal healthy children(control group)respectively.Grounding sections of the affected and healthy deciduous teeth were made to observe their roots;the den-tal pulp cells were separated and cultured.The characteristics of cell proliferation,differentiation and calcification were studied and compared between the two groups of children.MTT assay was performed to study the growth curves of the cells;RT-PCR was performed to evaluate the expression of tissue nonspecific alkaline phosphatase(TNSALP)at different stages;von Kosssa staining was used to test formed calcification nodules after 3 weeks of induction.Results: From the grounding sections,the root surface of the experiment group was not smooth with absorbed areas,cementum was absent.For proliferation activity and the expression of TNSALP,the dental pulp cells from experiment group was obviously lower than control group.Calcified nodules could be seen in both groups,but the nodules were less and the sizes were smaller in experiment group than in control group.Conclusion: In hypophosphatasia patients,not only the cementum but also the dentin were affected.The proliferation,TNSALP expression and calcification capability of the dental pulp cells were influenced in hypophosphatasia patients,and this may be related to the tooth calcification defect.

Objective To assess the effectiveness of different concentration of iodized salt for preventing iodine deficiency disorders. Methods Using the principle and method of systematic review, we searched Cochrane Library(from 1994 to Mar. 2007), Medline(from 1966 to Mar. 2007), BA(from 1969 to Mar. 2007), PubMed(from 1950 to Mar. 2007), OC1D(from 1950 to Mar. 2007), ISI Web of Knowledge(from 1966 to Mar. 2007), Vip (from 1989 to Mar. 2007), Wanfang(from 1997 to Mar. 2007), CBMDisc(from 1978 to Mar. 2007) and CNKI(1994 to Mar. 2007) and hand searched 6 relevant Chinese journals, including Chinese Journal of Preventive Medicine, Chinese Journal of Endemiology, Chinese Journal of Epidemiology, Chinese Journal of Control of Endemic Disease, Endemic Diseases Bulletin and Modern Preventive Medicine. We screened the for eligible studies according to the inclusion and exclusion criteria to be rigorously evealuatecl descriptly and qualitatively. Results Thirteen studies were included, of which, the first six were intervention trials with comparison, including two community intervention trials, which classified all objects into different groups, using iodized salt at different concentration as intervention, four were RCTs with different intervention methods, compare the iodized salt with other intervention measures. Seven were cross-sectional studies, which analyzed the iodine nutrition of people after the concentration of iodized salt was lowered down. Because of different interventions in control groups and different outcome measures, it was difficult to perform recta-analysis, a descriptive analysis of the results was presented. Most studies showed that urinary iodine level decreased as the concentration of iodized salt went down gradually. When the concentration of iodized salt went down to the best level recommended, goiter rate decreased obviously. Conclusions Iodized salt was considered as the hest method of iodine supply to prevent iodine deficiency disorders. But effectiveness of preventing iodine deficiency disorders with various concentration of iodized salt is different. To lower the concentration of iodized salt properly can not only prevent iodine deficiency disorders but also reduce the side effect of excess iodine intake to the minimum. And it can also save a lot of iodine resource. Well-designed community-based intervention trials with large sample size are needed to confirm the effect of different concentration of iodized salt on preventing iodine deficiency disorder.
