简介:目的:研究葛根素对妊娠期糖尿病大鼠的保护作用,并探讨其作用机制。方法:通过高脂饮食加注射链脲佐菌素(STZ)破坏胰岛β细胞的方法制备妊娠5天的糖尿病大鼠模型,选取96只模型大鼠随机分为:妊娠期糖尿病模型对照组、葛根素(40、80、160和320mg/kg)治疗组和盐酸二甲双胍200mg/kg治疗组,另取16只同期妊娠5天的正常大鼠作为正常妊娠对照组,并取16只同龄大鼠作为正常非妊娠对照组;每天灌胃给药1次,疗程为2周,妊娠期糖尿病模型对照组、正常妊娠对照组和正常非妊娠对照组均给予等体积的生理盐水。分别于给药前和给药后第7、14天分别测定各组大鼠空腹血糖水平;2周后,检测各组大鼠血清中血脂水平监测指标、抗氧化酶活性及氧化应激损伤监测指标,并通过苏木精-尹红(HE)染色观察各组大鼠肝脏组织和心肌组织病理形态学改变。结果:较正常非妊娠对照组,正常妊娠对照组大鼠空腹血糖水平、血清中血脂监测指标、抗氧化酶活性及氧化应激损伤监测指标均无显著性差异,并且肝脏组织和心肌组织无明显病理形态学改变。较正常妊娠对照组,妊娠期糖尿病模型对照组大鼠血清中血脂水平监测指标均显著升高、抗氧化酶活性显著降低、氧化应激损伤监测指标显著升高,差异均具有统计学意义,肝脏组织和心肌组织均出现明显的病理形态学改变。较妊娠期糖尿病模型对照组,葛根素160、320mg/kg治疗组大鼠空腹血糖水平显著降低;葛根素160、320mg/kg治疗组大鼠血清中总胆固醇(TC)、甘油三酯(TG)含量显著降低,其中320mg/kg治疗组低密度脂蛋白(LDL-C)含量显著降低且高密度脂蛋白(HDL-C)含量显著升高;葛根素80、160、320mg/kg治疗组大鼠血清中谷丙转氨酶(ALT)、谷草转氨酶(AST)、磷酸肌酸激酶(CPK)、丙二醛(MDA)含量显著降低,其中160、320
简介:目的:探讨阳和汤加减治疗中晚期类风湿关节炎活动期的临床疗效研究。方法:选取2020年1月-2022年1月期间,来我院治疗的100例类风湿关节炎患者作为研究对象,随机分为观察组、对照组各50人,观察组通过阳和汤加减治疗对患者进行诊治,对照组采取常规西医类风湿病医治手法,通过采用氨甲蝶呤和塞来昔布进行干预。随机分析患者病症治疗效果。结果:通过对两组患者身体康复程度对比,观察组治疗有效率明显高于对照组,P<0.05,组间数值比对具有统计学意义,且通过对两组患者在不同方式治疗后,在观察数据指标对比中,观察组患者数值变化,明显好于对照组(P<0.05),组间比对具有统计学意义。结论:在中晚期类风湿关节炎患者治疗期间,通过采取阳和汤加减治疗诊疗模式具有较高临床可行性,对患者祛风除湿以及通络经脉、温肾补血均有着明显效果,通过阳和汤治疗风湿关节炎患者,还能有效降低药物刺激带来的负面影响,帮助患者快速恢复,具有较高临床应用价值。
