To compare the impact of transurethral resection of prostate （TURP） on symptom scores and maximal flow rates （Qmax） in patients with equivocal bladder outlet obstruction （BOO） and definite BOO and to assess the relationship between the surgical outcomes and degree of preoperative BOO, we prospectively evaluated men with lower urinary tract symptoms and bladder outlet obstruction index （BOO1） greater than 20, who were refractory to conventional medical treatment and underwent TURP. Urodynamic evaluation, International Prostate Symptom Score （IPSS）, uroflowmetry, post-void residual volume （PVR） check and transrectal ultrasound were performed. 20〈B001〈40 was defined as equivocal BOO and BOO1 〉~40 as definite BOO. Changes of IPSS, Qmax, PVR and correlation analysis was performed between the degree of improvement of Qmax, subdomains of I PSS and BOO1. Fifty-four patients showed equivocal BOO and 80 patients showed definite BOO. Preoperatively equivocal BOO group and definite BOO group showed significant differences in maximal bladder capacity and prevalence of detrusor overactivity, whereas no difference was noted in prostate volume. Postoperatively both groups showed improvements in Qmax, obstructive （IPSSO） and irritative （IPSSI） subdomain of IPSS, but the degree of improvement in Qmax and IPSSI subdomain was statistically significantly greater in definite BOO group. The degree of improvement of Qmax and IPSSI showed weak correlation with preoperative BOO1. As a weak correlation was identified between preoperative degree of BOO and outcome of TURP, other factors other than BOO1 such as severity of patients＇ symptoms should be considered in deciding treatment modality.

nfluence of paradoxical sleep deprivation and sleep recovery on testosterone level in rats of different ages

Asian Journal of Andrology 2012年第2期14卷 330-334页

This study was performed to assess serum testosterone alterations induced by paradoxical sleep deprivation （PSD） and to verify their attenuation during sleep recovery （SR） based on different durations and ages. Wistar male rats aged 12 weeks for the younger group and 20 weeks for the elder group were randomly distributed into one of the following groups： a control group （cage and platform）, 3-day SD, 5-day SD, 7-day SD, 1-day SR, 3-day SR and 5-day SR groups. For PSD, the modified multiple platform method was used to specifically limit rapid eye movement （REM） sleep. Differences in the testosterone and luteinizing hormone levels between the younger group and the elder group according to duration of PSD and SR recovery were analysed. Testosterone continued to fall during the sleep deprivation period in a time-dependent manner in both the younger （P=-0.001, correlation coefficient r=-0.651） and elder groups （P=0.001, correlation coefficient r=-0.840）. The elder group showed a significantly lower level of testosterone compared with the younger group after PSD. Upon SR after 3 days of PSD, the testosterone level continued to rise for 5 days after sleep recovery in the younger group （P=0.013）, whereas testosterone concentrations failed to recover until day 5 in the elder group. PSD caused a more detrimental effect on serum testosterone in the elder group compared to the younger group with respect to decreases in luteinizing hormone （LH） levels. The replenishment of serum testosterone level was prohibited in the elder group suggesting that the effects of SD/SR may be age-dependent. The mechanism by which SD affects serum testosterone and how age may modify the process are still unclear.

The effect of diet-induced insulin resistance on DNA methylation of the androgen receptor promoter in the penile cavernosal smooth muscle of mice

引用

Asian Journal of Andrology 2013年第4期15卷 487-491,I0007页

作者： Jin-Wook Kim mi-mi oh Cheol-Yong Yoon Jae-Hyun Bae Je-Jong Kim Du-Geon Moon Department of Urology Korea University Medical Center Guro Hospital Seou1152-703 Korea and Department of Urology Korea University College of Medicine Seou1152 703 Korea

Population studies have suggested an association between diabetes and the symptoms of testosterone deficiency. Recently, the expression of the androgen receptor （AR） has been shown to be decreased in diabetic patients. Furthermore, diabetes has been shown to induce global methylation. In this study, we used an animal model to investigate whether diabetes results in increased methylation of the AR promoter and whether these changes are associated with the decreased expression of AR in penile cavernosal smooth muscle tissue. Twenty C57BL/6J mice were divided into two groups, receiving either high- （mature diabetic） or low- （mature control） caloric meals for 14 weeks. Another 10 mice were killed at 1 week （young control）. Animals in the mature diabetic group showed decreased testosterone levels, although this was not statistically significant. In both control groups, no significant methylation was observed in the AR promoter region CpG island （-85 to ＋339）. In the mature diabetic group, significant methylation was observed at ＋ 185 and ＋200 of the AR promoter. These changes were associated with increased homeostatic model assessment for insulin resistance （HOMA-IR） and decreased corpus cavernosal tissue mass and expression of AR mRNA and protein. We conclude that in these animals, insulin resistance increased the methylation of the GC-rich regions of the AR promoter, leading to decreased AR expression.

背景:铁死亡与缺血性脑卒中的发病密切相关,靶向铁死亡是一种治疗缺血性脑卒中有前景的方案,但具体调控靶点尚不明确。目的:通过生物信息学和机器学习方法筛选缺血性脑卒中铁死亡相关特征基因,并通过细胞实验进行验证,探讨铁死亡在缺血性脑卒中的作用。方法:基于GEO数据库和FerrDb数据库选取符合条件的缺血性脑卒中相关数据集和铁死亡表达数据集,通过t检验筛选铁死亡相关差异基因。对铁死亡相关差异基因进行GO功能富集分析与KEGG信号通路富集分析。通过PPI网络分析和机器学习筛选缺血性脑卒中铁死亡的特征基因,利用ROC分析和GSEA分析探究特征基因的准确性和生物功能。然后进行细胞实验,将HT22细胞分为对照组与缺血性脑卒中组,对照组不作任何干预,缺血性脑卒中组加入0.1 mol/L的H_(2)O_(2)干预24 h诱导细胞氧化应激和铁死亡,通过实时荧光定量RT-PCR和Western Blot验证铁死亡的发生和特征基因表达。结果与结论:(1)共获取45个铁死亡相关差异基因,GO和KEGG富集分析发现差异基因与氧化应激、自噬、铁死亡、脂肪细胞因子信号通路和线粒体代谢密切相关。(2)通过PPI网络中的MCODE插件和cytohubba插件与机器学习中的LASSO算法和SVM-RFE算法共鉴定出1个铁死亡特征基因核因子E2相关因子2(nuclear factor erythroid 2-related factor 2,NFE2L2)。(3)对NFE2L2进行ROC曲线分析,发现在训练集和验证集中构建的诊断预测模型具有良好的准确性与特异性;对NFE2L2进行GSEA分析,发现特征基因通过免疫、炎症反应、氨基酸代谢及神经因子调控等方面参与缺血性脑卒中发病机制的调控。(4)细胞实验的RT-PCR和Western Blot分析表明,与对照组对比,缺血性脑卒中组中的酰基辅酶A合成酶长链家族成员4 mRNA和蛋白表达水平显著增高(P<0.05),谷胱甘肽过氧化物酶4 mRNA和蛋白表达水平显著降低(P<0.05);与对照组对比,缺血性脑卒中组中特征基因NFE2L2 mRNA和蛋白表达水平显著增高(P<0.05)。(5)上述结果证实,缺血性脑卒中与铁死亡密切相关,靶向特征基因NFE2L2可以为研究和治疗缺血性脑卒中提供一定的思路与方向。
