Methods 40 cases with CHD were divided into TCDT group and control group randomly.
方法选择40例CHD患者，随机分为中药治疗组与西药对照组。
The level of serum VEGF in TCDT group was higher after treatment than pretreatment (P<0.01), and there was no much change in control group before and after treatment.
中药治疗组治疗后血清VEGF含量较治疗前明显升高（P<0.01），而西药对照组治疗前后血清VEGF含量无明显变化；
Conclusion the levels of serum VEGF and NO in TCDT group were higher after treatment than pretreatment, from which we can make a speculation that TGT may have the function of angiogenesis.
结论中药治疗组经治疗后血清vegf与NO含量均较治疗前明显升高，推测中药可能有促进血管生成的作用。
