Annexin5、ET-1、vWF在子痫前期患者胎盘中的表达
Zhongguo shiyan zhenduanxue, 2014 目的研究子痫前期患者胎盘中Annexin5、ET-1、vWF的表达水平,并探讨子痫前期发病机制。方法采用免疫组化方法检测子痫前期患者84例（轻度29例、早发重度型27例、晚发重度型28例）及对照组29例胎盘组织中Annexin5、ET-1、vWF的表达水平。结果①胎盘中Annexin 5在子痫前期各组表达强度明显低于对照组,差异均有统计学意义（P0.05）。②胎盘中ET-1在子痫前期各组表达强度明显高于对照组,差异有统计学意义（P晚发型>轻度子痫前期患者,差异仍有统计学意义 ...

血浆sCD40L、sICAM-1及血管内皮损伤相关细胞与子痫前期严重程度的相关性分析
Zhongguo shiyan zhenduanxue, 2017 目的探讨血浆白细胞分化抗原可溶性CD40配体（sCD40L）、可溶性细胞间粘附因子-1（sICAM-1）及血管内皮损伤相关细胞与子痫前期严重程度的相关性。方法选择年龄、BMI、检测孕周等临床一般资料相匹配的重度子痫前期、轻度子痫前期患者以及健康孕妇（对照组）各45例作为研究对象,采用ELISA法检测血浆sCD40L、sICAM-1水平,采用流式细胞仪检测内皮祖细胞（EPC）、血管生成性T细胞（Tang）含量,比较并分析其相关性。结果子痫前期组的血浆sICAM-1、sCD40L水平均明显高于对照组 ...

基于血栓弹力图评价阿司匹林联合低分子肝素对子痫前期作用的实验研究
Zhongguo shiyan zhenduanxue, 2021 目的分析比较血栓弹力图和凝血五项指标评价子痫前期患者接受低分子肝素治疗后的改善效果。方法选择2019年6月—2020年6月在石家庄市妇幼保健院进行产检并确诊子痫前期的孕妇120例,采用随机数字表法随机分为两组,每组各60例。阿司匹林组给予阿司匹林治疗,联合组在阿司匹林治疗的基础上联合低分子肝素治疗,治疗周期14d。检测治疗前后两组患者的凝血五项(PT、APTT、TT、FIB、D-D)指标,血小板计数,血栓弹力图指标。同时筛选同期在医院接受产检的60例健康孕妇作为对照组,检测并比较凝血五项指标 ...
