Neurophysiological effects of seminal vesicles / 中华男科学杂志

Seminal vesicles are involved in semen accumulation in the process of ejaculation, contracting and releasing seminal vesicle fluid accounting for about 50－80% of the semen, and the fructose in their secretions is an indispensable nutrient for sperm maturation. Thus, seminal vesicles are important male accessary glands closely related with the quality and quantity of sperm. In the process of semen accumulation, sympathetic and parasympathetic nerves participate in the regulation of the secretory function of seminal vesicle epithelia and the contraction of the smooth muscle layer as well as the distribution of adrenonergic, cholinergic, dopaminergic and various neurotransmitter receptors in the seminal vesicle epithelia and smooth muscle layer, which play a significant role in male fertility. This review discusses the neurophysiological effects of seminal vesicles in ejaculation.

Laparoscopic totally extraperitoneal inguinal hernia repair by using one-point-suturing fixed soft mesh / 中国现代普通外科进展

Objective:To investigate the feasibility and applicability of laparoscopic totally extraperitoneal (TEP) inguinal hernia repair by using one-point-suturing fixed soft mesh.Methods:90 male patients were retrospectively analyzed from Jan.2013 to Mar.2015,all of them were diagnosed with unilateral inguinal hernia and treated with TEP surgery.Among them,there were 55 patients with free of air bag and free of fixed TEP (free fixed group) and 35 patients with free of air bag and fixed by one-point-suturing TEP (one-point-suturing fixed group),all of patients were used by soft mesh.They were analyzed about their differences of postoperative pain,gastrointestinal function recovery time,the postoperative feeding time,the bedside movement time,the hospitalization time,and the incidence of postoperative complications.Results:Compared with the free fixed group,the operation time of the one-point-suturing fixed group was significantly shorter,the bedside movement time earlier,gastrointestinal function recovery time earlier,the postoperative feeding time earlier(P＜0.05),but the difference were not statistically significant in intraoperative blood loss,the postoperative pain,the hospitalization time,the incidence of postoperative seroma (P＞0.05),and therewere no recurrence in both groups.Conclusion:Compared with the free fixed TEP,the one-point-suturing fixed TEP has significantly shorter operation time,reduce the operation difficulty,and make the postoperative recovery faster,so it is safe,feasible and appropriate to application.
