Abstract:垂体腺苷酸环化酶激活肽(PACAP)是近年新发现的神经多肽,属于促胰液素/胰高血糖素/血管活性肽(VIP)家族中的新成员,广泛分布于脑和外周组织器官,尤其在内分泌胰腺、性腺、呼吸和生殖系统,在能量代谢、神经保护、免疫系统等发挥重要生理学功能。糖尿病是一种常见的主要以高血糖为特征的慢性代谢性疾病,糖尿病并发症日益严重威胁着人们的身体健康,已成为导致糖尿病患者致死、致残的主要原因。本文主要论述PACAP治疗糖尿病及其并发症国内外研究的最新进展。

Abstract: Objective To compare the expression of pinopodes, the marker of endometrial receptivity, during the implantation window in Kunming mice stimulated with two different doses of raloxifene (RAL). Methods Forty-eight 8-week-old female Kunming mice were randomly divided into 4 groups (n=12), namely saline group, clomiphene citrate (CC, 18 mg/kg) group, RAL (33 mg/kg) group and RAL (44 mg/kg group). In each group, the mice received intragastric administration of 1 mL of normal saline containing CC or RAL at the specified doses or saline only as indicated for ovulation induction, once daily for 2 days. The mice received then injection with 5 IU human chorionic gonadotropin (HCG) and mated and on day 4.5 of gestation, the pregnant mice were sacrificed for examination of the uterus with scanning electron microscopy. Results Abundant and well developed pinopodes were observed in the endometrium of the mice in the 2 RAL groups and in the saline control group. The mice in CC group showed obviously reduced endometrial pinopodes with poor development. Conclusions RAL at two different doses does not obviously affect the expression of pinopodes in the uterine epithelium of mice, suggesting the safety of RAL at these two doses for ovulation induction without causing adverse effects on endometrial receptivity.
