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 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.

Objective To explore the value of glypican-3(GPC-3)mRNA and paternally expressed 10(PEG10)mRNA in peripheral blood in diagnosis of metastasis in hepatocellular carcinoma(HCC). Methods With SYBR Green I as fluorescence signal,real-time fluorescent quantitative reverse transcription-polymerase chain reaction was employed to detect the expression of GPC-3 mRNA and PEG10 mRNA in peripheral blood from patients with HCC with metastasis(n=8),HCC without metastasis(n=12)and hepatic cirrhosis(n=11),and receiver operator characteristics curve(ROC)and specific parameters were adopted to analyse their value in predictive and exclusive diagnosis. Results The expression of GPC-3 mRNA and PEG10 mRNA in HCC with metastasis was significantly higher than that in HCC without metastasis and in hepatic cirrhosis(P<0.05),while there was no significant difference in the expression of GPC-3 mRNA and PEG10 mRNA between HCC without metastasis and hepatic cirrhosis.In single test,the sensitivities in the differential diagnosis between HCC with metastasis and HCC without metastasis were 66.7%for GPC-3 mRNA and 72.2%for PEG10 mRNA,and the specificities were 91.7%and 91.7%.respectively.The areas under ROC were 0.748 for GPC-3 mRNA and 0.812 for PEG10 mRNA.With two markers in parallel test,the sensitivity,specificity,negative likelihood and diagnostic accuracy were 90.7%,84.O%,0.11 and 83.3%,respectively.In serial test,the sensitivity,specificity,positive likelihood and diagnostic accuracy were 60.5%,98.7%,45.5 and 73.3%,respectively. Conclusion Detection of GPC-3 mRNA and PEG10 mRNA in peripheral blood may help to predict blood metastasis and extrahepatic metastasis of HCC,and PEG10 mRNA works better than GPC-3 mRNA.The serial test of GPC-3 mRNA and PEG10 mRNA is helpful to the predictive diagnosis of peripheral blood metastasis of HCC.

Objective To evaluate the efficacy and safety of the improved percutaneous balloon mitral valvuloplasty (PBMV) in elderly patients with mitral stenosis. Methods Elderly patients with severe mitral stenosis received an improved PBMV which included a modified way of atrial septal puncture and technique across the mitral valve. The left atrial pressrue (LAP), mean pulmonary pressure (MPA), mean gradient across the mitral value (MPG) and mitral valve area (MVA) were recorded and compared before and after the operation. Long term follow up were made. Results After operation, the LAP decreased [(25.3±6.7) mm Hg vs.(16.4±5.8) mm Hg,1 mm Hg=0.133 Kpa], MPG decreased [(17.6±6.7) mm Hg vs.(6.8±2.9) mm Hg], MPA decreased [(38.6±12.1) mm Hg vs. (29.2±9.8) mm Hg], MVA increased [(1.05±0.22)cm2 vs.(1.61±0.38)cm2] and the New York heart association heart function classification improved. The follow-up result showed that the effect of PBMV was constant. Conclusions Improved PBMV may be an effective and safe measure for patients with mitral stenosis.
