你翻译的东西，看得我差点疯掉。

就说结论部分吧，作者说了什么呢？我这里就不标引用了，一句一句的翻译

Authors’ conclusions

作者总结

Some herbal medicines show hypoglycaemic effect sin type 2 diabetes.

某些中药（字面翻译是草本药物）对于2型糖尿病有降低血糖（字面是“低血糖症效应”）的效果。

However, these findings should be carefully interpreted due to

the low methodological quality, small sample size, and limited number of trials.

但是，由于低下的方法学质量，过小的样品数，以及受限于实验的数量，这些结果需要谨慎的进行诠释。

In the light of some positive findings, some herbal

medicines deserve further examination in high-quality trials.

根据某些有积极效果的发现，某些中药值得在高质量的实验中进行进一步的检验。

===========================================================

感情人家还是不认可呀！

说明什么？即便是这些RCT也是非常不严谨，更遑提出个人的所谓经验，经历了。

说实话，我真的不知道你怎么得出“人家不认可”这个结论的。

首先不知道你说的认可是什么意思，其次，你可能看到的是负面的东西比如低质量的实验设计，过小的样本数量等等，但是我看到的就两句，一、某些中药对于二型糖尿病有降低血糖的效果，二 这些效果需要进行进一步的高水平实验检验予以确认。

作为一个科研工作者，看到这个结论应该想到的是：这个领域还有进一步拓展的空间，我应该改进现有的研究来得到更好的结果。只有这样，这个领域才有进步的可能。

而现在某些科研工作者看到的是：这个东西不能进入临床，掐死算了。

Main results

Eight randomised controlled trials were identified. A total 976 men were allocated to receive a PDE-5 inhibitor and 741 were randomised to the control groups. Overall, 80% of the participants suffered from type 2 diabetes mellitus. The weighted mean difference (WMD) for the International Index of Erectile Function (IIEF) questions 3 and 4 (frequency of penetration during and maintaining erection to completion of intercourse) was 0.9 (95% CI 0.8 to 1.1) and 1.1 (95% CI 1.0 to 1.2) at the end of the study period, in favour of the intervention group. The WMD for the IIEF erectile dysfunction domain at the end of the study period was 6.6 (95% CI 5.2 to 7.9) in favour of the PDE-5 inhibitors arm. The relative risk (RR) for answering "yes" to a global efficacy question ( "did the treatment improve your erections?") was 3.8 (CI 95% 3.1 to 4.5) in the PDE-5 inhibitors compared with the control arm. The WMD between the percentage of successful attempts in the PDE-5 inhibitors and in the control arm was 26.7 (95% CI 23.1 to 30.3). Mortality was not reported in any of the included trials. Adverse cardiovascular effects were reported in one study. Headache was the most frequent adverse event reported, flushing was the second most common event, with upper respiratory tract complaints and flu like syndromes, dyspepsia, myalgia, abnormal vision and back pain also reported in a descending order of frequency. The overall risk ratio for developing any adverse reaction was 4.8 (CI 95% 3.74 to 6.16) in the PDE-5 inhibitors arm as compared to the control.

Authors' conclusions

Sufficient evidence exists that PDE-5 inhibitors form a care that improves erectile dysfunction in diabetic men.
