DATA SYNTHESIS: Three level I and 9 level IV studies were identified and used in the systematic review of outcomes for intramedullary and extramedullary fixation for subtrochanteric fractures. Three level I studies were used to calculate a pooled relative risk for failure of fixation with a 95% confidence interval.

数据合成：3个1级可信度研究和9个4级可信度研究被选择，用来分析髓内与髓外固定治疗股骨转子下骨折的疗效。3个1级可信度研究用来计算内固定失败的风险较低，其可信区间为95％。

We have performed systematical studies on intrauterine transmission of hepatitis B virus and our studies suggested that HBV may occur through progressive infection of different placental layers until the virus reaches the fetoplacental circulation, which is the named "transplacental cellular traffic" except through placental tears with transfusion of infected maternal blood into the fetal circulation, which is the named "hematogenous transmission".

我室近年来对HBV宫内传播进行了系列研究，发现了胎盘在宫内传播中的作用，并提出了HBV宫内传播机制的假设：除血源性途径外，还可通过HBV在胎盘组织内的&细胞传递&途径，即HBV可以从母体蜕膜细胞通过&逐层转移&至胎儿绒毛毛细血管内皮细胞，导致胎儿感染。

To examine the data on CTC, the center analyzed 4 studies it considered to be of good or fair quality, which involved a total of 4312 patients. Depending on whether the scan was read by a gastroenterologist or an experienced radiologist, CTC identified 12 or 13 of a total of 14 colorectal cancers across the 4 studies. Compared with colonoscopy, the sensitivity of CTC ranged from 59% to 94% for detecting adenomas, depending on the size.

为了检验CTC研究数据，该中心分析四项被认为品质良好或不佳的研究，共有4，312位病患；依照该检验结果是否由肠胃科医师或是有经验的放射科医师判读，CTC在四项不同的研究中，侦测到12或13个大肠直肠癌，而总数量为14个；相较於大肠直肠镜，CTC的敏感度，在侦测腺瘤方面为59至94%，视肿瘤大小而定。
