We searched PubMed （1966- December 2011）, Embase （1974-December 2011） and the Cochrane Library Database （2011, Issue 12）. The assessed outcome measures were the change from baseline for the International Prostate Symptom Score （IPSS）, quality of life （QoL） score, peak urine maximum flow rate （Qmax）, QoL related to urinary symptoms and adverse effects. Two authors independently assessed the study quality and extracted data. All data were analysed using RevMan 5.1. The meta-analysis included four randomized controlled trials with a total of 2504 patients. The study durations were each 12 weeks. At the follow-up end points, the pooled results showed that the change from baseline for the silodosin group was significantly higher than the placebo group for the IPSS, QoL score and Qmax（mean difference （MD）=-2.78, P〈O.O0001; MD=-O.42, P--O.O04; MD= 1.17, P〈O.OOOOl,respectively） and patients felt more satisfied with QoL related to urinary symptoms in the silodosin group than the placebo group. Ejaculation disorder was the most commonly reported adverse effect. The pooled results also showed that the silodosin group was superior to the 0.2 mg tamsulosin group with respect to the IPSS and QoL score （IPSS： MD=- 1.14, P=O.02; QoL score： MD=-0.26, P=O.02） and inferior to the 0.2 mg tamsulosin group with respect to Qmax （MD=-0.85, P=O.01）. In contrast, there was no significant difference in the incidence of ejaculation disorder and dizziness between the silodosin and 0.2 mg tamsulosin groups. The current meta-analysis suggested that silodosin is an effective therapy for LUTS in men with BPH and is not inferior to 0.2 mg tamsulosin.展开更多

In order to obtain this intermediate, we developed a novel synthetic route by utilizing 2- nitrochlorobenzene as the starting material via O-alkylation, reduction, diazotization, acidolysis, etherification, condensation and hydrazinolysis. The highlight of this method lies on its convenience and economy in accessing this intermediate. 2007 Guo Hua Chert. Published by Elsevier B.V. on behalf of Chinese Chemical Society.
