摘　　要：目的:探讨抑郁症患者治疗前后血清脑源性神经生长因子(BDNF)水平变化及与早期改善的关系。方法:给予62例抑郁症患者(患者组)艾司西酞普兰抗抑郁治疗2周;以治疗后汉密尔顿抑郁量表(HAMD)-17减分率≥20%为界将患者分为早期改善组及非早期改善组;比较两组患者治疗前后血清BDNF水平变化及其与正常对照组(60人)的差异。结果:治疗前患者组血清BDNF水平[(1113.10±321.36)pg/ml]明显低于正常对照组[(1379.14±385.04)pg/ml](t=4.1487,P<0.01);治疗2周末[(1232.86±338.4)pg/ml]较治疗前显著提高(t=2.0207,P=0.0455),但是仍然低于正常对照组(t=2.2308,P=0.0275)。早期改善组(19例)血清BDNF水平治疗前[(1205.22±308.35)pg/ml]及治疗2周末BDNF增加值[(155.76±81.02)pg/ml]明显高于非早期改善组(43例)[(1041.26±292.18)pg/ml,(113.84±62.08)pg/ml;t=2.0032,t=2.2275;P均<0.05];早期改善组治疗前、后血清BDNF水平与正常对照差异无统计学意义(F=1.83,P=0.1657)。结论:抑郁症患者血清BDNF水平显著降低,但降低幅度较小及治疗后提升幅度较大的患者可获得早期改善。Objective： To explore the relation of serum brain-derived neurotrophic factor （BDNF） level change with early improvement of antidepressant treatment in patients with depression. Method： Sixty-two depression patients were treated by escitalopram for 2 weeks. Acording to the point of reduced rate of Hamilton depression scale （HAMD）-17 〉120% after treatment,the patients were divided into early improvement group and no-early improvement group. The changes of serum BDNF level before and after treatment were compared be- tweet the two groups and 60 normal controls （normal control group）. Results：The baseline serum BDNF level of patients [ （ 1113.10 ± 321.36）pg/ml ] was sinificantly lower than the normal controls [ （ 1379.14 ± 385.04） pg/ml ] （t = 4. 1487,P 〈 0. 01 ）. After treatment, the BDNF level [ （ 1232.86 ± 338.4） pg/ml ] was increased significantly than before treatment （ t = 2. 0207, P 〈 0. 05）, but was still significantly lower than the normal con- trol group（t =2. 2308 ,P =0. 0275）. In early improvement group （19 cases） the baseline BDNF level [ （1205.22± 308.35 ） pg/ml ] and the added value ofter the treatment [ （ 155.76± 81.02 ） pg/ml ] were significantly higher than those in the no-early improvement group （43 cases） [ （ 1041.26 ±292.18 ） pg/ml, （ 113.84± 62.08 ） pg/ ml ; t = 2. 0032, t = 2. 2275 ; all P 〈 0. 05 ]. The serum BDNF level in the early improvement group before and after treatment had no significant difference from normal controls （F = 1.83, P = 0. 1657 ）. Conclusion：Serum BDNF level in depressive patients are significantly lower. But the patients with smaller reduce and bigger rise after treatment will improve earlier.
