Autoimmune thyroid diseases (AITD) are destructive inflammatory or anti-receptor autoimmune diseases characterized by reactivity to self-thyroid antigens. However, the effects of Se on the cytokines in AITD are still unclear. So we researched the role of Selenium (Se) and Thl/Th2 cytokine productions in the pathogenesis of autoimmune thyroid diseases (AITD).展开更多

文摘目的 探讨中医益气养阴活血法辨证治疗2型糖尿病(Type 2 diabetes, T2DM)合并慢性心力衰竭(Chronic heart failure, CHF)患者的临床疗效。方法 选取2021年1月—2022年1月期间唐山市中医医院内分泌一科收治的T2DM合并CHF患者102例作为研究对象,按随机数字表法分为对照组与治疗组,每组各51例。对照组给予常规西医治疗,治疗组在对照组基础上联合中医益气养阴活血法辨证治疗,均治疗12周。观察比较两组患者西医疗效、中医证候疗效、安全性及治疗前后血糖水平[空腹血糖(Fasting blood glucose, FPG)、餐后2 h血糖(Blood glucose 2 h after a meal, 2 h PG)、糖化血红蛋白(Glycosylated hemoglobin, HbAlc)]、心功能指标[6分钟步行试验距离(6 min walking test, 6MWT)、左室射血分数(Left ventricular ejection fraction, LVEF)、N末端B型脑钠肽前体(N-terminal B-type brain natriuretic peptide precursor, NT-pro BNP)]、生活质量评分[T2DM生活质量(Quality of life specific scale for diabetes patients, DSQL)、CHF生活质量(Minnesota Living with Heart Failure Questionnaire, MLHFQ)]变化。结果 临床疗效:治疗后治疗组西医疗效总有效率96.08%(49/51)高于对照组82.35%(42/51),差异有统计学意义(P<0.05);治疗组中医证候疗效总有效率92.16%(47/51)高于对照组68.63%(35/51),差异有统计学意义(P<0.05)。血糖水平:治疗后两组患者血糖FPG、2 h PG及HbAlc水平均较治疗前降低,差异有统计学意义(P<0.05);且治疗组血糖FPG、2 h PG及HbAlc水平均明显低于对照组,差异有统计学意义(P<0.05)。心功能指标:治疗后两组患者心功能6MWT、LVEF水平较治疗前升高,NT-pro BNP水平较治疗前降低,差异有统计学意义(P<0.05);且治疗组6MWT、LVEF水平高于对照组,NT-pro BNP水平低于对照组,差异有统计学意义(P<0.05)。生活质量:治疗后两组患者DSQL、MLHFQ评分均较治疗前降低,差异有统计学意义(P<0.05);且治疗组DSQL、MLHFQ评分均明显低于对照组,差异有统计学意义(P<0.05)。安全性:治疗期间,两组患者不良反应均为轻度或一过性,未影响治疗,且不良反应发生率组间比较,差异无统计学意义(P>0.05)。结论 中医益气养阴活血法辨证治疗T2DM合并CHF效果显著、安全性高,有利于控制患者血糖,改善心功能与生活质量。
