目的:观察田基黄对湿热证糖尿病患者血糖的影响。方法:选择2019年1月-2020年6月在本院接受诊治但疗效欠理想的湿热证糖尿病患者80例,根据随机对照法分组,分为对照组(n=40)、观察组(n=40),两组均维持原有的方案予生活方式干预和/或西药降...目的:观察田基黄对湿热证糖尿病患者血糖的影响。方法:选择2019年1月-2020年6月在本院接受诊治但疗效欠理想的湿热证糖尿病患者80例,根据随机对照法分组,分为对照组(n=40)、观察组(n=40),两组均维持原有的方案予生活方式干预和/或西药降糖,观察组在此基础上加用田基黄汤药口服,两组均治疗3个月,比较两组治疗前后的中医证候积分、糖化血红蛋白、餐后2 h血糖、空腹血糖、肝肾功能以及不良反应发生情况。结果:观察组总有效37例(92.5%)高于对照组30例(75.0%),两组比较差异有统计学意义(χ^(2)=4.501,P=0.034)。两组治疗后主症、次症评分较治疗前均有下降,但与对照组相比,观察组治疗后各项指标显著降低,差异均有统计学意义(P<0.05)。两组患者治疗后的HbA1c、FPG、2 h PG水平较治疗前均有降低,但与对照组相比,观察组各项指标均下降显著,差异均有统计学意义(P<0.05)。两组治疗前后的肝肾功能及不良反应发生情况比较,差异均无统计学意义(P>0.05)。结论:湿热型糖尿病患者服用田基黄中药液后,临床症状得到显著改善,血糖指标得到有效控制,无明显的不良反应,值得临床推广。展开更多
