摘要
背景:研究精神分裂症的候选基因是探索其病因的主要方法之一,与精神分裂症有关联的重要候选基因之一是脑源性神经营养因子基因。目的:了解精神分裂症患者脑源性神经营养因子基因C270T多态性与精神分裂症的关联。设计:病例-对照,对比观察。单位:中南大学精神卫生研究所。对象:选择2003-03/10在中南大学湘雅二医院精神卫生研究所男女病房住院的精神分裂症患者194例为患者组,男95例,女99例;年龄15～59岁。同期在中南大学湘雅医学院按与患者组年龄,性别相当的条件招募的健康者187人为对照组,男88人,女99人;年龄18～42岁。本人及家庭无精神病史。两组对象均为湖南汉族(同民族的遗传同质性比较好)人群,患者本人或家属对本研究签署书面知情同意书。对照组本人签署书面知情同意书。方法:①评定精神病性症状的有无及各项症状的严重程度采用阳性与阴性症状量表包括阳性症状量表(7项),阴性症状量表(7项)和一般精神病理量表(16项)及3个补充项目评定攻击危险性(7项评分:1为无,7为极重度)。评定于患者入院当天,在病房内完成。②采用聚合酶链反应技术检测纳入对象的脑源性神经营养因子基因C270T多态性基因型的分布频率。③各组间频数比较用χ2检验。主要观察指标:①患者组和健康对照组脑源性神经营养因子基因C270T多态性的分布频率。②不同基因型的阳性与阴性症状量表得分。结果:精神分裂症患者194例,健康者187人均进入结果分析。①患者组的C/T基因型分布频率(26.8%)明显高于对照组(5.9%)(χ2=32.71,df=1,P<0.01)。患者组的T等位基因分布频率(14.4%)明显高于对照组(2.7%)(χ2=36.19,df=1,P<0.01)。②基因型为C/T患者阳性与阴性症状量表总分、阳性症状量表分、阴性症状量表分、一般精神病理量表总分分别为59～121分;9～42分,平均(20.08±6.16)分;8～41分,平均(19.
BACKGROUND： The study on the candidate gene of schizophrenia was one of the major ways of exploring its etiology. One of important candidate genes associated with schizophrenia is the brain-derived neurotrophie factor gene（BDNF） OBJECTIVE： To explore the association between schizophrenia and C270T polymorphism of BDNF gene, DESIGN： Case-control and comparative observation SETTING： Institute of Mental Health of Central South University PARTICIPANTS： Totally 194 patients with schizophrenia, including 95 males and 99 females aged from 15 to 59 years, hospitalized in man and women wards in the Institute of Mental Health, Xiangya Second Hospital of Central South University from March to October 2003 were set as patients group. Controls were selected among the healthy volunteers of Xiangya Medical College was included in terms of age and gender comparable with patients group. Altogether 187 cases of controls, of whom 88 males and 99 females were studied. Their age ranged from 18 to 42 years old with the average of （26±7） years old.Those with psychosies and severe somatopathy were excluded. The patients and their family member have no history of psychosis .All the subjects were of Hunan Han nationality. Either the patient or his or her family members signed the written consent form. Individuals in the control group also signed the written consent form. METHODS： ① Positive and Negative Symptom Scale （PANSS） includes positive symptom scale （PANSS-P） （7 items）, negative symptom scale （PANSS-N） （7 items） and General Symptom Scale （PANSS-G） （16 items）, altogether 30 items, as well as 3 additional items to evaluate the attack fatalness were used to evaluate whether the psychic symptom existed or not and the degree of severity of each symptom（7-item scoring： 1 was without, 7 was very severe） . The patients were evaluated on the day of hospitalizing in the ward. ②Polymerase chain reaction technique was used to detect the distribution frequency of C270T polymorphism of B
