ABSTRACT
Congenital adrenal hyperplasia(CAH) is a group of autosomal recessive disorders caused by deficiency of specific enzymes in the adrenocortical hormone synthesis pathway, resulting in impaired corticosteroid synthesis. 21-hydroxylase deficiency is the most common type of CAH, and the disorder can lead to impaired fertility in patients. Most current studies have focused on fertility problems in female CAH patients. The most common causes of impaired fertility in men with 21-OHD include testicular adrenal rest tumors(TART), low gonadotropin secretion, and inappropriate glucocorticoid therapy. This article reviews the causes of impaired fertility and its treatment in male patients with 21-OHD, with the aim of providing guidance for improving the fertility of male patients with 21-OHD.
ABSTRACT
Objective To assess the effects of artificial cordyceps sinensis(Jin shuibao) on the numbers of podocytes and epithelial-mesenchymal transition in diabetic rats.Methods Diabetes was induced by intraperitoneal injection of low dose streptozocin.Sprague-Dawley rats were randomly divided into three groups:control group (CON),diabetic model group(DM),and artificial cordyceps sinensis treatment group(CS).After intervention for 8 weeks,the numbers of podocytes were estimated hy immunohistochemistry.The expressions of nephrin,desmin,and monocyte chemoattractant protein-1 (MCP-1) were detected.Results Compared with control group,DM group showed significantly decreased podocyte numbers and nephrin mRNA,with increased desmin and MCP-1 levels(P＜0.05).While the numbers of podocytes and nephrin mRNA were increased,and the expressions of desmin and MCP-1 were decreased in CS group as compared with those in DM group (all P＜0.05).Conclusions Artificial cordyceps sinensis notably improves epithelial-mesenchymal transition of podocytes,and increases the number of podocytes in diabetic rats.
