抑郁发作自杀未遂患者脑源性神经营养因子水平及其相关因素研究

Objective To investigate the possible role of brain-derived neurotrophic factor(BDNF)in the pathophysiology of attempted suicide in depressive episode patients.Methods The subjects were 23 depressive episode patients who had recently attempted suicide.24 depressive episode patients without suicide attempt.and 30 sex-age-and education matched healthy controls.The Hamihon Depression Rating Scale-24 items(HAMD24),Beck Helpless Rating Scale(BHS)and Self-rating Idea of Suicide Scale (SIOSS)was used to evaluate the severitv of symptoms.The seruln level of BDNF was detected with sandwich ELISA.Pearson correlation coefficients wag used to measure the correlations between serum BDNF and the related illness variables.Results There were significant difierences in the serum level of BDNF between patients with attempted suicide,pailents without suicide attempt and normal controls(F=21.927,P＜0.05).Post hoc analysis showed the serum BDNF levels in patients with attempted suicide [(57 ±16)ng/L]were lower than that in patients without[(75±28)ns/L;P＜0.05],and were lower in patients without suicide attempt[(75 ±28)ng/L]than that in normal controls[(111 ±39)ng/L;P＜0.01].In patients with attempted suicide,the serum BDNF was negatively correlated to the duration of depressive episode(r=-0.541,P=0.008),the mean BHS score(r=-0.494,P=0.017)and the mean SIOSSscore(r=-0.754.P=0.000).Conclusion The results suggest that the decreased serum brain-derived neurotrophic factor is related to the pathophysiology of attempted suicide in depressive episode patients.

精神分裂症首次发病患者冲动和自杀行为与血浆瘦素及总胆固醇的相关性研究

目的 探讨精神分裂症患者冲动、自杀行为与血浆瘦素及胆固醇之间的相关性.方法 106例精神分裂症首次发病患者用简明精神病评定量表(BPRS)、阳性和阴性症状量表(PANSS)、汉密尔顿抑郁量表(HAMD24)及Beck绝望量表(BHS)进行评定;按有无冲动、自杀行为分为自杀组(24例)、冲动组(31例)、非自杀非冲动组(以下简称患者对照组,51例),32名体检职工为正常对照组,所有入组对象(患者在服药前)测定体质量指数(BMI)、血浆瘦素和总胆固醇.结果 (1)正常对照组[(4.8±0.9)mmol/L]和患者对照组[(4.3±1.1)mmol/L]总胆固醇均高于自杀组[(3.7±1.0)mmol/L]及冲动组[(3.6±1.0)mmoL/L;P<0.05～0.01],而冲动组与自杀组之间、正常对照组与患者对照组之间的差异无统计学意义(P>0.05);正常对照组血浆瘦素[(13.4±6.7)μg/L]高于患者对照组[(8.9±3.8)μg/L]、自杀组[(6.7±2.6)μg/L]及冲动组[(5.6±4.2)μg/L;P<0.05～0.01],患者对照组高于自杀组及冲动组(P<0.05),而自杀组与冲动组的差异无统计学意义(P>0.05).(2)4组的血浆瘦素及总胆固醇均与BMI呈正相关(r=0.49～0.64;P<0.01);自杀组、冲动组的血浆瘦素和总胆固醇与PANSS阳性分、PANSS攻击分、BPRS分、HAMD分、BHS分均呈显著负相关(r=-0.35～-0.72;P<0.05～0.01);患者对照组的血浆瘦素、总胆固醇与PANSS攻击分、BPRS分、HAMD分、BHS分均呈显著负相关r=-0.29～-0.48;P<0.05～0.01).结论 精神分裂症患者的冲动、自杀行为及疾病严重程度与血浆瘦素及总胆固醇有一定的相关性.

抑郁症自杀未遂者血浆瘦素及总胆固醇水平研究

目的 探讨血浆瘦素及总胆固醇与抑郁发作自杀未遂的关系.方法 对抑郁发作自杀未遂者(自杀未遂组,25例)和抑郁发作无自杀行为者(无自杀组,30例)采用汉密尔顿抑郁量表(HAMD24)、Beck绝望量表(BHS)及自杀意念自评量表(SIOSS)评定抑郁严重程度、绝望程度和自杀意念的强烈程度;32例体检职工为对照组,所有入组对象服药前测定体质量指数、血浆瘦素和总胆固醇.结果 (1)自杀未遂组的HAMD-24[(38.9±9.4)分]、BHS[(13.4±4.1)分]、SIOSS评分[(17.8±4.1)分]均高于无自杀组[分别为(26.2±6.3)分、(7.8±4.0)分、(12.5±4.3)分;P＜0.01].(2)自杀未遂组的总胆固醇[(3.3±0.9)mmol/L]及血浆瘦素水平[(6.1±3.7)μg/L]明显低于无自杀组[分别为(3.6±1.2)mmol/L,(9.4±4.4)g/L;P＜0.05～0.01],而无自杀组又明显低于正常对照组[分别为(4.8±0.9)mmol/L,(13.4±6.7)μg/L;P＜0.05～0.01].(3)3组的血浆瘦素及总胆固醇均与BMI呈正相关(P＜0.01);自杀未遂组和无自杀组血浆瘦素和总胆固醇与HAMD-24分、BHS及SIOSS分均呈显著负相关,且两组的血浆瘦素与总胆固醇之间呈显著正相关(P＜0.01);而正常对照组的血浆瘦素与总胆固醇之间无显著相关性(P＞0.05).结论 低水平的血浆瘦素可能是抑郁发作自杀未遂的一个危险因素.
