1、目的观察西格列汀联合二甲双胍治疗2型糖尿病(T2DM)合并非酒精性脂肪肝(NAFLD)患者的疗效,并探讨其对患者糖脂代谢、肝功能、脂肪因子的影响。方法选取2020年5月至2022年6月平顶山市第一人民医院收治的116例T2DM合并NAFLD患者作为研究对象,按随机数表法分为二甲双胍组和西格列汀联合组各58例。二甲双胍组患者予以二甲双胍治疗,西格列汀联合组患者在二甲双胍组治疗的基础上联合西格列汀治疗。治疗6个月后,比较两组患者的临床效果,以及治疗前后的糖脂代谢相关指标空腹血糖(FPG)、糖化血红蛋白(HbA1c)、高密度脂蛋白胆固醇(HDL-C)和低密度脂蛋白胆固醇(LDL-C)、肝功能相关指标
2、谷氨酰基转移酶(GGT)、天冬氨酸转氨酶(AST)、丙氨酸氨基转移酶(ALT)水平、脂肪因子血清趋化素(chemerin)、摄食抑制因子-1(nesfatin-1)水平、体质量指数(BMI)、肝脏脂肪含量、CT肝脾密度比值、非酒精性脂肪性肝纤维化评分(NAFLDFS),并比较两组患者治疗期间的不良反应发生情况。结果治疗6个月后,西格列汀联合组患者的治疗总有效率为77.59%,明显高于二甲双胍组的60.34%,差异有统计学意义(P0.05);治疗6个月后,西格列汀联合组患者的HbA1c、FPG、LDL-C水平、血清GGT、AST、ALT、chemerin、nesfatin-1水平、BMI、肝脏脂
3、肪含量、NAFLDFS评分分别为(6.690.64)%、(6.870.76)mmol/L、(2.490.30)mmol/L、(41.782.71)U/L、(34.092.38)U/L、(35.752.09)U/L、(72.4910.73)ng/mL、(5.701.85)ng/mL、(25.370.95)kg/m2、(8.271.28)%、(0.320.06)分,明显低于二甲双胍组的(7.240.78)%、(7.460.82)mmol/L、(2.840.41)mmol/L、(46.473.35)U/L、(38.123.26)U/L、(39.522.63)U/L、(80.5112.09)ng/mL
4、、(6.622.09)ng/mL、(26.181.02)kg/m2、(9.411.56)%、(0.470.08)分,HDL-C水平、CT肝脾密度比值分别为(1.920.68)mmol/L、0.930.08,明显高于二甲双胍组的(1.570.59)mmol/L、0.810.12,差异均有统计学意义(P0.05)。结论西格列汀联合二甲双胍治疗T2DM合并NAFLD患者临床疗效较好,可有效改善糖脂代谢和肝功能指标,降低BMI、肝脏脂肪含量、脂肪肝与肝纤维化程度,并下调血清chemerin、nesfatin-1水平,具有较高的安全性。【关键词】2型糖尿病;非酒精性脂肪肝;西格列汀;二甲双胍;疗效;糖脂

31、血脂、血压、体质量等多种危险因素采取综合干预10。积极治疗NAFLD可延缓NAFLD向终末期肝病进展,改善患者预后11-12。因此,在治疗T2DM合并NAFLD 患者时,应首选具有降糖作用,同时兼具减重、降脂、减轻胰岛素抵抗与脂肪肝作用的药物。本研究采用西格列汀联合二甲双胍联合治疗T2DM合并NAFLD患者,结果显示,治疗6个月后,西格列汀联合组治疗总有效率高于二甲双胍组,差异有统计学意义(P0.05);西格列汀联合组 HbA1c、FPG、LDL-C水平、血清GGT、AST、ALT水平、BMI、肝脏脂肪含量、NAFLDFS评分均低于二甲双胍组,HDL-C水平、CT肝脾密度比值均高于二甲双胍组,
32、差异有统计学意义(P0.05),与田松明13、周玉等14研究结果相似,表明西格列汀联合二甲双胍治疗可有效改善糖脂代谢与肝功能,降低BMI、肝脏脂肪含量、脂肪肝与肝纤维化程度,提升疗效。分析原因在于,二甲双胍作为治疗T2DM的首选药物,在改善机体胰岛素抵抗的同时,可在一定程度上改善BMI。对合并NAFLD的T2DM患者,采取二甲双胍治疗,对部分患者的疗效一般,需与其他降糖、降脂药物联合使用,以提高疗效。且二甲双1849海南医学2023年7月第34卷第13期Hainan Med J,Jul.2023,Vol.34,No.13胍对改善肝脏脂肪变性的作用有限15。而西格列汀可有效抑制机体肾脏对葡萄糖的
33、再吸收,下调肾葡萄糖阈值,加速尿糖排泄,起到降糖效应;且其能调节机体内源性葡萄糖的生成,空腹状态下胰高血糖素表达提升,胰岛素敏感性升高,可减轻胰岛素抵抗16;同时,西格列汀有一定的降脂、减重作用;另有研究指出,西格列汀还可提升锌-A2-糖蛋白、脂联素水平,减轻体重,抑制游离脂肪酸表达,抑制肝脏脂质生成,改善慢性炎症状态,减轻脂质过氧化反应,进而降低脂肪肝病变程度与纤维化程度,下调肝脏脂肪含量17。西格列汀联合二甲双胍可起到协同调节糖脂代谢、减重、改善机体对胰岛素抵抗与肝功能等作用,进而提升治疗效果。机体内脂肪组织的功能紊乱可导致脂肪因子的异常表达18。chemerin、nesfatin-1均为
34、新型脂肪因子,其中chemerin参与糖脂代谢与胰岛素抵抗调节,且可促进炎症因子分泌,增加肝脏炎症反应,加剧胰岛素抵抗,促进T2DM、NAFLD发生、进展;nesfatin-1可调节血糖、抑制摄食、降低体重等,对机体能量代谢具有重要作用,且可参与胰岛素抵抗进程,在T2DM患者体内,其表达呈代偿性提高。本研究结果证实,治疗6个月后,西格列汀联合组血清chemerin、nesfatin-1水平低于二甲双胍组,差异有统计学意义(P0.05),表明西格列汀联合二甲双胍治疗T2DM合并NAFLD不良作用少,具有较高的用药安全性。这可能是因为,西格列汀已经过临床验证,给药剂量在安全范围内,合理用药不会显著
35、增加不良反应发生风险。综上所述,西格列汀联合二甲双胍治疗T2DM合并NAFLD患者临床疗效较好,可有效改善糖脂代谢与肝功能,降低BMI、肝脏脂肪含量、脂肪肝与肝纤维化程度,并下调血清chemerin、nesfatin-1水平,具有较高的安全性。参考文献1Lee CH,Lui DT,Lam KS.Non-alcoholic fatty liver disease and type2 diabetes:An update J.J Diabetes Investig,2022,13(6):930-940.2Zhu D.Study on the clinical effect of metformin

48、7.225.61)ms,明显低于对照组的(53.715.21)mm、(65.676.26)ms,差异均有统计学意义(P0.05);干预后,观察组患者的用力肺活量(FVC)、肺泡通气量(VA)和最大呼气中段流量(MMEF)分别为(2.440.51)L、(5.310.80)L/min、(2.280.51)L/s,明显高于对照组的(2.010.47)L、(4.560.75)L/min、(1.900.46)L/s,差异均有统计学意义(P0.05);干预后,观察组患者的心率变异性指标总标准差(SDNN)、两个相邻RR间期互差(PNN50)、差值均方根(RMSSD)分别为(132.8116.51)ms、(
49、6.810.90)%、(43.285.51)ms,明显高于对照组的(121.4015.47)ms、(6.120.85)%、(36.895.46)ms,差异均有统计学意义(P0.05);干预后,观察组患者的MLHF-Q评分、中医证候积分分别为(26.303.42)分、(15.002.53)分,明显低于对照组的(31.425.15)分、(17.553.17)分,6MWT距离为(356.4849.96)m,明显长于对照组的(293.4869.64)m,差异均有统计学意义(P0.05)。结论心脏康健导引功对慢性心力衰竭易损期患者的治疗干预能够改善其心肺功能、心率变异性,提高生活质量和运动耐量。【关键词】心脏康健导引功;慢性心力衰竭;易损期;心肺功能;心率变异性;生活质量【中图分类号】R541.6【文献标识码】A【文章编号】10036350(2023)13185105Intervention effect of he
