All devices which may increase bone mass in the lateral trochanter, theoretically, may be helpful in lowering the incidence of hip fractures.

所有有助于增强外侧大转子骨密度的措施理论上都有助于降低髋部骨折的发生率。

The development speed of gynogenetic embryos was later than that of the control group, and aneuploids were found in this study. The obvious improved survival of trochophore larvae with a peak at 40s UV exposure suggested the presence of a Hertwig effect in the gynogenesis of A. pectinata. When sperms were irradiated for 40s, the cleavage rate was relatively high (51.2%), the developmental rate of D-larvae became zero, and the rate of haploid reached the highest (36.8%).

经紫外线照射的精子受精后所产生的单倍体胚胎发育速度慢于正常受精所产生的二倍体胚胎，各照射组均出现非整倍体。40s照射组中卵裂率达到51.2%，D型幼虫发生率为0，单倍体率最高，达到36.8%，出现"Hertwig效应"。

The positive rate of true inborn metabolic error was 0.99％(2/2100), and the false positive rate 1.28％(29/2100) in this study.

在本研究中，先天性代谢异常的发生率为0.09％(2/2100)，筛检中伪阳性的比率为1.28％(29/2100)。

The incidence of impotence in TVP group has been 2.4% and in TURP group 14.5%.

术后阳萎发生率： TVP 组2.4%， TURP 组14.5%(P ＜0.05)。

But rates in the United States have increased by more than one-third in the last twenty-five years.

但美国的发生率在最近的25年间上升了三分之一。

Countries with taller women have higher rates of twinning compared to countries with shorter women.

与女性平均身高较低的国家相比，在女性平均身高较高的国家孪生的发生率也较高。

Methods 300 cases (560 ears)of temporal CT axial images which were divided into two groups were retrospectively analyzed by statistics methods. There were 158 cases(316 ears)in normal group and 142 cases(244 ears)in abnormal group .The incidence of high jugular bulb , dehiscent jugular bulb, anterior location of sigmoid sinus, large sinus tympani, aberrant internal carotid artery, dehiscent of the facial nerve canal, excess of Korner's septum and mastoid antrum dysplasia were recorded.

回顾性分析300例(560耳)颞骨的HRCT轴位像，根据诊断结果将其分为正常组与疾病组，正常组158例(316耳)，疾病组142例(244耳)，统计以下变异的发生率：①颈静脉球高位②颈静脉球裸露③乙状窦前置④鼓室窦深位⑤迷走颈内动脉⑥面神经管水平段裸露⑦岩鳞隔过长⑧鼓窦缺如，并对结果进行统计学分析。

The incidence and mortality of stress ulceration bleeding in treatment group were lower than that in the control.

结论早期干预可以降低急性脑卒中后应激性溃疡出血的发生率和病死率。
