摘要:

目的: 通过观察丹蛭降糖胶囊对2型糖尿病患者大血管Wnt/β-链蛋白(Wnt/β-catenin)、糖原合成酶激酶-3(GSK-3β)通路表达,以及对颈动脉内膜中层厚度(IMT)和斑块面积的影响,评价丹蛭降糖胶囊对2型糖尿病患者大血管病变的保护作用。方法: 将102例2型糖尿病患者随机分为对照组和治疗组各51人。所有患者给予基础药物(常规口服降糖药物)治疗,治疗组采用基础药物+丹蛭降糖胶囊,疗程均为16周。结果: 16周后治疗组总有效率84.31%,优于对照组的64.71%,差异有统计学意义(P<0.05);两组治疗前后比较中医证候积分、FPG、2 hPG、HbA1c、TC、TG、LDL、HDL、颈动脉IMT及斑块面积水平都有所改善(P<0.05或P<0.01);组间比较,治疗组中医证候积分、2 hPG、HbA1c、TG及LDL水平下降,具有统计学差异(P<0.05或P<0.01);治疗组IMT改善情况优于对照组(P<0.05),但斑块面积改善情况无统计学意义(P>0.05)。治疗后,治疗组血清βcatenin水平较对照组显著降低(P<0.01),血清GSK3β水平比对照组降低,差异有统计学意义(P<0.05)。结论: 丹蛭降糖胶囊可以显著缓解2型糖尿病患者临床症状,并在一定程度上改善或逆转颈动脉硬化进程。

Abstract:

AIM: To evaluate the protective effect of Danzhijiangtang capsule on vasculopathy of type 2 diabetes mellitus (T2DM) patients by observing the expression of Wnt/β-catenin, GSK-3β, and the change of carotid intima media thickness (IMT) and plaque area. METHODS: One hundred and two T2DM patients were randomly allocated into the control group and the treatment group (n=51). Both groups received conventional therapy (hypoglycemic drugs orally), while the treatment group was given extra Danzhijiangtang capsule. Therapy was conducted for 16 weeks.RESULTS:The total effective rate of the treatment group was significantly better than that of the control group (84.31% vs. 64.71%, P<0.05). Traditional Chinese Medicine (TCM) symptom scores, FPG, 2 hPG, HbA1c, TC, TG, LDL, HDL, carotid intima media thickness and plaque area were improved in both groups. Compared with the control group, TCM scores, 2 hPG, HbA1, TG and LDL decreased significantly (P<0.05  or P<0.01) in the treatment group, which also presented better improvement of IMT (P<0.05) though the comparison of plague area exhibited no significant difference (P>0.05); The expressions of Wnt/β-catenin and GSK-3β also decreased significantly in the treatment group (P<0.05). CONCLUSION: Danzhijiangtang capsule can alleviate the clinical symptoms of T2DM, and can improve or even reverse carotid atherosclerosis to a certain extent.
