OBJECTIVE:To observe the effect of Compound glycyrrhizin on serum VEGF of patients with alopecia areata. METHODS:36 alopecia areata patients were selected as trial group and treated with Compound glycyrrhizin(50 mg/time,3 times/d) for 3 months. Double-antibody sandwich ELISA method was adopted to determine the content of VEGF in serum before and after treatment. 36 healthy volunteers were included in control group,and serum content of VEGF in control group was compared with trial group. RESULTS:Compared with control group,the serum content of VEGF was lower in trial group,with statistical signifi-cance(t=5.863,P0.05). CONCLUSIONS:Compound glycyrrhizin can cure alopecia areata through increasing serum level of VEGF.%目的：探讨复方甘草酸苷对斑秃患者血清中血管内皮生长因子（VEGF）的影响。方法：选取36例斑秃患者作为试验组，口服复方甘草酸苷片（50 mg/次，3次/d）进行治疗，疗程3个月。采用双抗体夹心酶联免疫吸附（ELISA）法测定患者治疗前后血清中VEGF的含量。另将36例体检正常人群设为对照组，以其血清中VEGF的含量与试验组进行比较。结果：与对照组比较，治疗前试验组患者血清VEGF的含量较低，差异有统计学意义（t＝5.863，P＜0.05）。治疗后，试验组患者血清VEGF的含量较治疗前升高，差异有统计学意义（t＝4.351，P＜0.05）；且治疗后试验组患者血清VEGF的含量与对照组比较差异无统计学意义（t＝1.678， P＞0.05）。结论：复方甘草酸苷可能通过提高血清中VEGF的水平达到治疗斑秃的作用。
