【摘要】 目的 观察黄芪注射液并用贝那普利对早期糖尿病肾病(DN)的临床疗效及其作用机理。
方法 将40例早期DN患者随机分为对照组(20例)和
治疗组(20例),对照组为常规西药和贝那普利治疗,治疗组加用黄芪注射液。比较两组血压、空腹血糖(FBG)、血肌酐(Scr)、尿素氮(BUN)、血浆白蛋白、尿白蛋白排泄率(UAER)、尿β2微球蛋白(β2-MG)的改变。
结果 两组在治疗前各项指标差异无显著性;经4周治疗后,两组血压、UAER、尿β2-MG较治疗前均有明显下降(
P<0.05或
P<0.01),且治疗组较对照组下降更明显;FBG、Scr、BUN治疗组较对照组稍低,但差异无显著性(
P>0.05)。
结论 黄芪注射液并用贝那普利联合常规西药治疗早期DN临床疗效比常规西药联合贝那普利疗效显著,其机理与降低TGF-β1,改善DN早期的肾脏高灌注、高滤过等有关。

Observation on effect of combined use of radix astragali injection and benazepril for treatment of early diabetic nephropathy
【Abstract】 Objective This study investigated the effects and mechanisms of the combined use of Radix Astragali injection (RAI) and benazepril for treatment of eearly diabetic nephropathy (DN).
Methods Forty patients with early DN were randomly assigned to the control group (n=20) treated by benazepril and the experiment group (n=20) treated by RAI and benazepril.Additionally,the conventional western medication was used by all patients in both groups.Blood pressure,urine albumin excretion rate (UAER),uricβ2-microglobulin (β2-MG),fasting blood glucose (FBG),serum creatinine (SCr),blood urea nitrogen (BUN) and plasma albumin were measured before and after the treatment for all participants and data were collected.Changes of these indexes were compared within and between the two groups.
Results There were no significant differences of the baseline data in all these indexes between the experiment group and the control group.After four weeks of the treatment,blood pressure,UAER and uricβ2-MG were significantly lowered in both groups (
P<0.05 or
P<0.01) and the decreases in the experiment group were more obvious.The FBG,SCr and BUN levels of the experiment group were slightly lower than those of the control group,but the differences between the two groups were not statistically significant (
P>0.05).
Conclusion Combination of RAI and benazepril with conventional western medication has a
better effect on the treatment of early DN than only benazepril with conventional western medication.Its mechanisms are related with decreasing TGF-β1,improving early high renal perfusion and filtration of DN and so on.

糖尿病肾病(DN)是糖尿病(DM)的微血管并发症之一,也是其死亡原因之一。据1999年上海市肾脏病登记系统的统计资料,DN约占慢性肾功能衰竭的14%[1],既严重危及患者的身心健康,又造成了巨大的
经济负担。DN临床上以出现持续的蛋白尿为主要标志,故要减轻糖尿病患者肾脏损害及向终末期进展的速度,关键是减少蛋白尿。本院
应用黄芪注射液并用贝那普利治疗早期DN,疗效满意。现报告如下。
1 资料与方法
1.1 病例选择选择我科2000年6月~2005年6月住院的2型糖尿病患者40例,符合1999年WHO糖尿病诊断标准,按Mogensen的DN分期标准[2],诊断为DN Ⅲ期,即微量白蛋白期,尿白蛋白排泄率(UAER)在20~200μg/min,持续>3个月。
1.2 分组 将入选的40例早期DN患者随机分为治疗组及对照组各20例。治疗组男11例,女9例;年龄35~66岁,平均(48.8±12.9)岁;病程5~22年,平均(12.8±7.3)年;空腹血糖(FBG)(8.23±2.78)mmol/L;收缩压(SBP)(145±11)mmHg,舒张压(DBP)(90±10)mmHg;UAER(96.74±36.42)μg/min。对照组男10例,女10例,年龄34~68岁,平均(49.1±13.4)岁;病程4~21年,平均(13.5±6.9)年;空腹血糖(FBG)(8.30±3.01)mmol/L;收缩压(SBP)(144±12)mmHg,舒张压(DBP)(91±12)mmHg;UAER(95.86±38.51)μg/min。两组高血压均发现于糖尿病之后(不使用ARB、ACEI制剂控制血压),并除外发热、感染、心衰、糖尿病酮症酸中毒、肾毒性药物应用、其他肾病、肾动脉狭窄等。两组患者性别、年龄、病程、FBG、血压、肾功能等指标经统计学处理差异无显著性(
P>0.05),具有可比性。
1.3 治疗方法 对照组用北京诺华制药有限公司生产的贝那普利(商品名:洛汀新)片,口服1次10mg,每日1次。治疗组在上述治疗基础上同时加用上海福达制药有限公司生产的黄芪注射液20ml,加在生理盐水250ml中静滴,每日1次。2周为1个疗程,连续2个疗程。两组治疗前后均包括低盐低蛋白糖尿病饮食,戒烟酒,适量运动及降糖、降血脂等常规治疗。
