Species diversity and stability of natural secondary communities in different layers with different cutting intensities 10 years later were investigated by calculating Marglef Richness index（R）,Shannon-Wiener diversity index（H）,Simpson diversity index（P）,and Pielou Evenness index（J）.Results show that the values of R,H and P among different layers are listed in a decreasing order：the shrub layer the arbor layer the herb layer,all the three indices values reach the maximum under medium selective cutting intensity after 10 *** J value of the shrub layer shows a concave parabolic change with the increase in cutting intensity;it shows a linear increase for the arbor layer,whereas the J value of the herb layer shows an opposite change *** values of R at different cutting intensities had high significant difference,but other indices had not significant *** stability of communities at different cutting intensities after 10 years is non-cutting low selective cutting intensity medium selective cutting intensity high selective cutting intensity extra-high intensity clear *** stability of communities at different cutting intensities after 10 years shows that the greater cutting intensities,the worse the stability is.

Background： BiNary cast syndrome （BCS） was a postoperative complication of orthotopic liver transplantation （OLT）, and the reason for BSC was considered to relate with ischemic type biliary lesions. This study aimed to evaluate the relationship between BCS following OLT and the hepatic artery resistance index （HARt）, and to observe pathological changes and morphology of biliary casts. Methods： Totally, 18 patients were diagnosed with BCS by cholangiography following OLT using choledochoscope or endoscopic retrograde cholangiopancreatography. In addition, 36 patients who did not present with BCS in the corresponding period had detectable postoperative HARI on weeks I, 2, 3 shown by color Doppler flow imaging. The compositions ofbiliary casts were analyzed by pathological examination and scanning electron microscopy. Results： HARI values of the BCS group were significantly decreased as compared with the non-BCS group on postoperative weeks 2 and 3 （P 〈 0.05）. Odds ratio （OR） analysis of HARI 1, HARI 2, HARI 3 following the operation was 〉1 （OR = 1.300： 1.223 and 1.889, respectively）. The OR of HARI 3 was statistically significant （OR - 1.889; 95% confidence interval - 1.166-7.490; P - 0.024）. The compositions of biliary casts were different when bile duct stones wcrc present. Furthermore, vascular epithelial cells were found by pathological examination in binary casts. Conclusions： HARI may possibly serve as an independent risk factor and early predictive factor of BCS. Components and formation of binary casts and bile duct stones are different.

目的：系统评价重复经颅磁刺激（ rTMS）预防慢性偏头痛中的疗效和安全性。方法计算机检索PubMed、The Cochrane library、EMbase、Web of Science、CBM、CNKI和WanFang Data数据库，搜集rTMS预防慢性偏头痛的随机对照试验（RCT），检索时限是从建库开始至2016年7月，采用RevMan 5．3进行Meta分析。结果纳入3项RCT研究，共有133例患者。 Meta分析结果显示：高频rTMS预防治疗1个月后rTMS组偏头痛患者头痛发作频率改善情况（MD＝7．55，95％CI：6．88～8．21，P＜0.00001），偏头痛指数（发作频率＆#215;头痛程度）改善情况（MD＝23．31，95％CI：21．50～25．12，P＜0.00001）均优于对照组。低频rTMS刺激在预防慢性偏头痛方面疗效不显著。两项研究显示不良反应主要有易怒、肌震颤、嗜睡等，但这些症状在短时间内都可自行缓解。结论当前证据显示，高频rTMS能有效预防慢性偏头痛，不良反应少。
