衣原体致病机制研究进展

衣原体是一类具有独特两相发育周期的专性胞内寄生菌,可引起人类多种疾病.衣原体致病主要依赖菌体脂多糖、膜蛋白、质粒编码蛋白、分泌的效应因子等,其或介导衣原体黏附和入侵宿主、引起炎症和病理损伤,或调控宿主细胞功能以利衣原体胞内生长,或抑制宿主免疫细胞以便衣原体逃逸免疫杀伤.这些发现在分子水平上阐述了衣原体的致病机制,为更好...     

The significance of the kallikrein-kinin system in the pathogenesis of essential hypertension

The levels of plasma kininase II (ACE), a high molecular weight-kininogen (HMW), alpha 2-mega-globular protein (alpha 2M), prekallikrein (PK), alpha 1-antitrypsin (alpha 1 AT) were determined in essential hypertension and control groups. The results showed that there is significant increase of ACE and PK activity and HMW content in patients with essential hypertension than in control group (P less than 0.001). No changes in alpha 2M and alpha 1AT were found. These results suggest that human plasma kallikrein system was inhibited in patients with essential hypertension.     

Research progress on the pathogenesis of aortic dissection

Aortic dissection(AD) is a cardiovascular emergency with a high mortality rate, and the risk of death is estimated to increase by 1%-2% per hour. AD is complicated by variable clinical manifestations, and early detection and treatment can give more time for the treatment of patients.Hypertension is the most common cause of AD. In China, 65%-75% of patients with AD have poor blood pressure control. Patients with AD who are less than40 years of age are more likely to suffer from genetic diseases. ...     

糖尿病周围神经病相关发病机制研究进展

糖尿病周围神经病（DPN）作为糖尿病最常见的并发症,一定程度上表现为周围神经功能障碍,影响患者的生活质量。基于近年来国内外对DPN相关发病机制的研究,本文主要围绕DPN在代谢、免疫、基因、降糖药等方面的相关发病机制展开综述,为今后DPN的机制研究与治疗提供思路。     

阴道毛滴虫分子致病机制的研究进展

阴道毛滴虫是一种常见的寄生原虫,以性传播为主。近年来对阴道毛滴虫致病机制的研究日益受到重视,本文从黏附因子、纤黏连蛋白、层黏连蛋白、G蛋白、成孔蛋白、蛋白酶和细胞骨架等方面综述阴道毛滴虫的分子致病机制。     

外伤性癫痫发病机制的研究进展

外伤性癫痫是脑外伤最严重的并发症之一,其基础研究日益受到重视,但目前其发生机制尚不清楚。该文主要介绍外伤性癫痫可能的发生机制：癫痫灶超微结构的变化包括神经元、神经胶质细胞和血脑屏障的变化,载脂蛋白E等位基因ε4（APoE-ε4）,铁和自由基损伤,兴奋性氨基酸（EAAs）的过量释放,脑海马区突触重建等。
