肠道菌群在多囊卵巢综合征胰岛素抵抗中的作用机制

多囊卵巢综合征(PCOS)是一种高度异质性的妇科内分泌疾病,临床表现多为排卵障碍、月经失调、多毛、痤疮甚至不孕,常伴有肥胖、胰岛素抵抗(IR)、血脂异常等代谢性疾病,其发病机制尚不明确.IR是PCOS的主要病理基础,与性激素分泌异常、卵泡发育异常、子宫内膜容受性降低等生殖功能改变密切相关.肠道菌群被称为人体第二基因组,...

Research Progress on the Mechanism of Gastrointestinal Microbiome in Insulin Resistance of Polycystic Ovary Syndrome

Polycystic ovary syndrome (PCOS) is a highly heterogeneous gynecological endocrine disease with clinical manifestations of ovulation disorders, menstrual disorders, hirsute, acne and even infertility. It is often accompanied by metabolic disorders such as obesity, insulin resistance (IR) and dyslipidemia. The pathogenesis of PCOS remains unclear. IR is the main pathological basis of PCOS, which is closely related to the changes of reproductive function such as abnormal level of sex hormones, abnormal follicle development and the reduced endometrial receptivity. Gut microbiome, known as the "second genome of human body", plays a variety of functions in maintaining the homeostasis of the host′s internal environment, such as preventing pathogens from invading the host, regulating absorption and metabolism of nutritional materials, and maintaining the stability of immune system and nervous system. In recent years, many studies have reported that the changes of gut microbiome composition can cause IR through endotoxemia, bile acid, chronic low-grade inflammation and other ways, thus promoting the occurrence and development of PCOS.
