随着临床试验数量的增加,系统评价越来越多地被用于分析总结跨学科的科研结果。Meta分析作为一种综合证据的常用方法,能提供总结大量证据的简捷途径,但meta分析不可能适合全部多相性的临床研究,为此,就要用一种定性的方法替代它。总体印象法(Global Impression Method,GIM)作为系统评价中综合多相性临床随机对照试验(Randomized Controlled Trial,RCT)结果的常用方法,作者对其研究现状进行了总结。结果提示,使用总体印象法和最佳证据合成简化版判定森林图的结果与Meta分析的结果存在中等以上程度的内在及交互一致,因此,研究者可用GIM总结RCT结果。经过正常程序以后,在决定证据的精确强度时,个别研究的质量也被考虑,因此,GIM值得在针灸研究中应用。

肥胖现已成为患者和医生一大共同的健康难题。因生活方式及生活质量等原因,节食和运动虽是主要的减肥方法,但其依从性却往往不高。其他诸如药物及手术等方法则有潜在的严重副作用,且远期效果并不理想。为寻找一种有效且副作用小的疗法,中医药尤其是针刺和耳针疗法已成为这一领域的一个研究主题。因此,将2014年6月以前全文发表的以针刺及耳针疗法治疗肥胖的随机对照试验纳入综述。结果发现:与运动相比,针刺治疗减肥的效果具有一定优势。然而,因现有研究的局限性,仍需大样本的随机对照试验来证实针刺是否应该纳入减肥的常规治疗。

Tracer diffusion mechanism in amorphous Co and Co81.5B18.5 solids is studied using the statistic relaxation model containing 2 × 105 atoms. It was found a large number of microscopic bubbles which could break up and leads to diffusion. A new diffusion mechanism via the microscopic bubbles is proposed and the diffusion coefficient determined in term of this mechanism is in reasonable agreement with experimental data. The decrease in diffusion coefficient upon thermal annealing observed experimentally for most amorphous alloys is interpreted as a result of reduced number of microscopic bubbles.

利用越南海防市沿海地区HONDAU验潮站52a的潮汐观测资料,采用基本统计方法和潮汐调和分析法研究该地区海洋水位变化特征。结果显示：该地区海平面、潮差均呈现上升趋势,年变化率分别是1.89mm/a、3.07mm/a;对采样间隔为1h的潮位连续观测数据作调和分析,得到调和常数的时间序列,分析显示各主要分潮的调和常数均为时变量,且与周期性（3～5a）El Nino和La Nina现象相关;余水位年上升率是1.76mm/a,平均增、减水位分别是12.48cm和-13.36cm。增、减水位持续时间小于24h的累积频率分别是95.5%和93.3%,增减水位持续时间大于48h的只占1%～2%。绝对余水位值小于50cm的占大多数,大约99%,增减水位绝对值大于100cm的只占0.1%左右。
