Objective To evaluate the therapeutic effects and adverse events on treatment of primary premature ejaculation (PE) with paroxetine hydrochloride and/or tamsalosin .Methods 225 cases of healthy men ,a history of lifelong PE and an intravaginal e‐jaculation latency time(IELT) < 120 sec were included in this study .The patients were divided into three groups(with 75 cases in each group) .Group A were given paroxetine hydrochloride 20 mg/d for 8 weeks ;group B were given tamsalosin 0 .2 mg/d for 8 weeks ;group C were given paroxetine hydrochloride and tamsalosin for 8 weeks .The effects and adverse events were evaluated by the overall change and fold increase in average IELT and the mean change in all four measures of the premature ejaculation profile (PEP) .Results The reliable data from 198 patients were achieved .The mean IELT after treatment were significantly improved in all groups than that of before treatment (P<0 .05) .The mean IELT in group C was increased for 8 .15 min after treatment .The in‐creased folds of mean IELT in group C (8 .02 folds) was significantly higher than that in group B (1 .98 folds)and group A (6 .92 folds)(P<0 .01) .The mean PEP scores that include measures of perceived control over ejaculation ,satisfaction with sexual inter‐course ,ejaculation‐related personal distress ,ejaculation‐related interpersonal difficulty were significantly improved in all groups after treatment .The mean PEP scores in group C had more significant improvements than that in group A and B .The prevalence of ad‐verse events in group A ,B ,C were 10 cases(13 .3% ) ,2 cases(2 .6% ) and 9 cases(12 .0% ) ,respectively .Conclusion Paroxetine hydrochloride combined with tamsalosin lead to better therapeutic effects and could be a priority selection for the treatment of pri‐mary PE .

Objective To investigate the efficiency and mechanism of differentiation of reprogrammed adipose-derived stem cells (ADSCs) to neurons in vitro.Methods ADSCs from rats were cultured in vitro and then purified and identified.ADSCs at the third passage were divided into three groups:ADSCs without lentivirus-mediated gene transfection (blank group),ADSCs transfected with lentivirus carrying no neurogenin2 (Ngn2) (empty virus group) and ADSCs with lentivirus-mediated transfection of Ngn2 (Ngn2 group).All groups were induced in the medium containing cell growth factor for 15 days.The positive expression of neuron-specific nuclear protein (NeuN) in three groups was detected using immunofluorescence method so as to observe the efficiency of neuron differentiation.Expression variances of Mash1,Hes1 and Dll1 in each group were detected by Western blot analysis and the mechanism of differentiation was also discussed.Results After 15 days of induction,positive expression rate of NeuN in Ngn2 group,empty virus group,blank group was 90.12％,45.34％ and 40.26％ respectively,with significant differences among groups (P ＜ 0.01).Western blot analysis showed that Ngn2 group had a significantly higher expression of Dll1 (P ＜0.01) and obvious lower expressions of Hes1 and Mash1 (P ＜0.01),as compared with empty virus group and blank group.However,there were no significant differences of expression levels of Dll1,Mash1 and Hes1 between empty virus group and blank group (P ＞ 0.05).Conclusions After induction,the ratio of neuron differentiation of reprogrammed ADSCs is increased by almost 99％,as compared with simple ADSCs.The increased dfferentiation of reprogrammedADSCs to neurons may be associated with the inhibition of notch signaling through up-regulating Dll1 and down-regulating Mash1 and Hesl.
