益气活血方治疗气阴两虚夹瘀型糖尿病肾病Ⅲ期疗效及对VEGF、TGF-β1的影响

Yiqi Huoxue Decoction in the treatment of Qi and yin deficiency and stasis type diabetic nephropathy in stageⅢand its effect on VEGF and TGF-β1

目的:观察益气活血方治疗糖尿病肾病(DN)Ⅲ期属气阴两虚夹瘀型患者的疗效及对血管内皮生长因子(VEGF)、转化生长因子-β(TGF-β1)的影响。方法:选取2018年09月~2019年12月在江西中医药大学附属医院内分泌科就诊的气阴两虚夹瘀型DNⅢ期患者60例为研究对象,分为观察组和对照组各30例。两组均参照指南及专家共识进行DN的一般治疗(降糖、降压、调脂等),对照组予胰激肽原酶肠溶片口服,一次120 U,每日3次,观察组予中药益气活血方加减口服,每日1剂,分早晚2次服用;两组均连续干预8周。检测患者治疗前后血FPG、PBG、HbA1c、β2-MG、BUN、SCr、VEGF、TGF-β1及尿液mALB、UACR水平,并计算两组治疗前后eGFR;观察两组中医证候积分变化,比较其临床疗效。结果:治疗8周后,两组临床总有效率比较,差异具有统计学意义(P<0.05);观察组中医证候积分较治疗前及对照组均明显降低(P<0.05);观察组FPG、HbA1c、PPG、mALB、β2-MG、UACR、VEGF、TGF-β1水平均较对照组明显降低,差异具有统计学意义(P<0.05),观察组SCr、BUN水平较治疗前有所下降,eGFR较治疗有所上升,差异无统计学意义(P>0.05)。结论:益气活血方治疗DNⅢ期属气阴两虚夹瘀型患者,不仅有助于血糖水平的降低,中医证候的改善,而且能减轻早期肾功能损伤,减少尿微量白蛋白,延缓肾功能的进一步恶化,同时具有较好的安全性,其机制可能与降低VEGF、TGF-β1水平,从而延缓肾小管间质瘢痕纤维化及抑制肾小球毛细血管硬化有关。

Objective:To observe the efficacy of Yiqi Huoxue decoction in the treatment of patients with diabetic nephropathy(DN)stageⅢwith qi and yin deficiency and stasis and its effects on vascular endothelial growth factor(VEGF)and transforming growth factor-β(TGF-β1).Methods:Totally 60 patients with stage DN of Qi-yin deficiency and stasis type DN who were treated in the Endocrinology Department of the Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine from September 2018 to December 2019 were selected as the research subjects who have been divided then into the observation group and control group with 30 cases each using the remainder method Patients in both groups were referred to the guidelines and expert consensus for general treatment of DN(hypoglycemic,antihypertensive,lipid-lowering,etc.).The control group was given pancreatic kallikrein enteric-coated tablets orally once,120U a time,3 times a day,and the observation group was given the traditional Chinese medicine Yiqi Huoxue Decoction orally with one dose daily,and twice a day in the morning and evening;the two groups were intervened continuously for 8 weeks.Blood FPG,PBG,HbA1c,β2-MG,BUN,SCr,VEGF,TGF-β1,and urine mALB and UACR levels before and after treatment were detected,and eGFR before and after treatment in both groups were calculated;this study also observed changes in TCM syndrome scores in the two groups,and Compared its clinical efficacy.Results:After 8 weeks of treatment,the total clinical effective rate of patients in the observation group was 93.3%,which was significantly higher from the control group of 76.6%(P<0.05);the TCM syndrome scores in the observation group were significantly lower than those before treatment and in the control group(P<0.05);The levels of FPG,HbA1c,PPG,mALB,β2-MG,UACR,VEGF,and TGF-β1 in the observation group were significantly lower than those in the control group,with significant differences(P<0.05).The levels of SCr and BUN in the observation group were significantly lower.Compared with that before treatment,eGFR increased,but there was no significant difference(P>0.05).Conclusion: Yiqi Huoxue Decoction for the treatment of patients with DN typeⅢqi-yin deficiency and stasis type not only helps to lower blood sugar levels,and improve TCM syndromes,but also can reduce early renal damage,reduce urine albumin,and delay the the further worsening of kidney function.It may be further worsened and has better safety.The mechanism may be related to reducing the levels of VEGF and TGF-β1,thereby delaying the fibrosis of tubulointerstitial scar and inhibiting glomerular capillary sclerosis.
