目的 研究难治性强迫症(Refractory obsessive-compulsive disorder,ROCD)脑源性神经营养因子(brain derived neurotrophic factor,BDNF)血清浓度水平与认知功能的研究。方法 方便选取2012年7月—2014年4月在该院就诊的41例ROCD组和57名相匹配的健康对照组为研究对象,采用耶鲁-布朗强迫量表(Yale-Brown obsessive-compulsive Scale,Y-BOCS)和成套神经心理状态评估工具(RBANS)评定患者的起病年龄、病程、Y-BOCS总分、RBANS总分等状况,用酶联免疫法测定血清BDNF的浓度水平。 结果 ROCD的血清BDNF浓度水平为(1.45±0.33)ng/mL,明显比健康对照组要低(P<0.01),差异有统计学意义。认知功能中语言方面差异有统计学意义(P<0.01)。ROCD的血清BDNF浓度水平与性别、起病年龄、病程、Y-BOCS总分、RBANS总分无明显相关。结论 ROCD存在语言功能障碍,BDNF可能参与强迫症的发生。

[Abstract]Objective To study the relationship of Refractory obsessive compulsive disorder(ROCD)BDNF serum level with cognitive function.Methods Convenient in July 2012—April 2014 in our hospital clinic of 41 cases of match ROCD and 57 cases of healthy control group as the research object,used the Yale-Brown,obsessive compulsive Scale(Y-BOCS)and complete sets of neuropsychological state evaluation tool(RBANS)to assess the patient's condition of onset of the age,course of the disease,Y-BOCS score,enzyme league immune method for measuring the concentration of serum BDNF levels. Results The serum BDNF concentration of ROCD was(1.45±0.33)ng/mL,which was significantly lower than that of healthy controls(P<0.01),and the difference was statistically significant.There are significant differences in cognitive function(P<0.01).The serum BDNF level of ROCD was not related to gender,onset age,course of disease,Y-BOCS total score and RBANS total score.Conclusion There are language dysfunctions in ROCD;BDNF may participate in ROCD's occurrence.

脑源性神经营养因子(BDNF)作为一种重要的神经营养因子,其作用是保护及促进中枢和外周神经细胞损伤后再生,调节细胞增殖分化,参与海马长时程增强效应形成及神经元可塑性调节,有研究认为BDNF与精神分裂症患者的认知功能有相关性[1],而ROCD患者的BDNF和认知……
