Objective To systematically evaluate the effectiveness and safety of fluoxetine in treating premature ejaculation (PE). Methods All randomized controlled trials (RCTs) on fluoxetine treating PE published from July 1996 to May 2012 were collected in the following databases: MEDLINE, EMbase, PubMed, Ovid, The Cochrane Central Register of Controlled Trials, CBM and CKNI. According to the inclusion and exclusion criteria, literature screening, data extraction and quality assessment were conducted independently by two reviewers. Then meta-analysis was performed using RevMan 5.0 software. Results A total of 6 RCTs involving 221 patients were included finally. The results of meta-analysis showed that, as for effectiveness, there was no significant difference in the intravaginal ejaculatory latency time (IELT) between the two groups before the treatment (WMD=–0.21, 95%CI −4.79 to 4.37, P=0.93), but the IELT of the fluoxetine group was obviously longer than that of the control group after the treatment, with a significant difference (WMD=134.54, 95%CI 79.78 to 189.30, Plt;0.000 01). The results of sensitivity analysis indicated that the IELT of the fluoxetine group was longer than that of the control group, with a significant difference (WMD=155.19, 95%CI 130.64 to 179.75, Plt;0.000 01). As for safety, the fluoxetine group was higher in the incidence of adverse reaction than the control group, with a significant difference (OR=5.49, 95%CI 2.43 to 12.38, Plt;0.000 1). Conclusion Current evidence indicates that fluoxetine can improve the symptoms of PE patients, obviously prolong the IELT, and improve the quality of sexual life; and it is tolerable to patients with mild adverse reactions and is suitable for long-term intake. For the limited quantity of the included studies, we herein believe that, to obtain more evidence, it is necessary to further confirm the diagnosis and therapeutic criteria of PE, to design and conduct more multicenter and large scale clinical studies by adopting the internationally recognized indexes, and to perform a long-term follow-up．
Objective To evaluate the effects of selective serotonin reuptake inhibitors ( SSRIs) on sleep apneas in Sprague-Dawley ( SD) rats. Methods Thirty adultmale SD rats were randomly divided into two groups ( 15 rats in each group) . The treatment group and the control group were injected intraperitoneally with paroxetine ( 10 mg· kg- 1 · d - 1 ) and sterile distilled water ( 2 mL· kg- 1 · d - 1) for 7 days respectively. Parameters about sleep apnea and sleep structure were measured before and after the treatment. Results In the treatment group, there was a significant reduction of apnea index ( AI) from ( 12. 4 ±3. 7)times /hour to ( 7. 4 ±2. 2) times/ hour ( P = 0. 000) . Both post sigh apnea index ( PSAI) and spontaneous apnea index ( SPAI) were decreased significantly ( P = 0. 000 and 0. 021 respectively) in non-rapid eye movement ( NREM) sleep, but not in REM sleep. REM sleep was reduced from 8. 6% to 8. 0% ( P =0. 013) and its latency was increased from ( 54. 1 ±48. 4) min to ( 110. 9 ±43. 4) min ( P = 0. 001) in the treatment group, as well as the sleep-onset latency [ from ( 20. 7 ±9. 1) min to ( 30. 0 ±15. 7) min, P =0. 038] . Conclusion Paroxetine can reduce sleep apneas in SD rats during NREMsleep. Its effects on sleep structure include reducing REM time, increasing REM latency and sleep-onset latency.
