Objective To confirm the expression and localization of COX-2 gene in mature rat testis,as COX-2 not only plays a central role in inflammation by up-regulating the synthesis of prostaglandins,but also mediates critical reproductive functions by other mechanisms. Methods In the mature Wistar rats,COX-2 expression and its localization were examined by using immunohistochemistry,RT-PCR and Western-blot. Results The results of RT-PCR and Western-blot showed that COX-2 mRNA and its protein exist in the testis. Expression of COX-2 was localized in spermatogenic cells on immunohistochemical study.No COX-2 expression in sertoli cells and leydig cells was found. Conclusions The present study confirmed the expression of COX-2 in rat testis and its localization in spermatogenic cells.These suggest that COX-2 may play a role in spermatogenesis.

Objective To explore influence of valsartan on MAU of patients with DN at early stage.Methods 163 patients with DN at early stage were randomly divided into experimental group and control group.Two groups were given routine therapy, and experimental group were added the therapy of valsartan.Period of treatment was 24 weeks, and compared the UAER, Cr, BUN of two groups.Results After treatment of 24 weeks, UAER, Cr, BUN of experimental groups was (142.4 ± 15.6) μg/min, ( 68.7 ±9.4) μmol/L, (3.5 ± 1.2 ) mmol/L, compared with (195.8±23.7)(μg/min,(93.8 ± 13.6) μmol/L, (6.3 ±1.5) mmol/L before treatment, had significant difference (t = 13.675,11.287,2.469,all P<0.05).Compared with( 199.6 ±24.7)μg/min,(87.7 ±11.3)μmol/L、(6.2 ± 1.3)mmol/L of control group after treatment, declined more significantly (t = 13.246,10.312,2.518,all P<0.05).There was no serious complications occurred in two groups.Conclusion Valsartan used in patients with DN at early stage,can significantly improve the function of kidney and enhance clinical effect,decline the side reaction.
