摘要:
目的 探讨血清S100B蛋白浓度与首发未服用抗精神病药的精神分裂症患者精神病理症状间的关系.方法 采用酶联免疫(ELISA)方法 检测64例首发未服用抗精神病药精神分裂症患者和66名正常对照的血清S100B蛋白浓度,比较2组间的差异;采用阳性和阴性症状量表(PANSS)评定精神病理症状,分析血清S100B蛋白浓度与PANSS评分、患者年龄、发病年龄、病程间的关系.结果 ①患者组血清S100B浓度明显高于对照组,筹异有统计学意义[(0.27±0.13)μg/L vs(0.11±0.04)μg/L,t=10.89,P<0.001];②患者组中偏执型、瓦解型、未分化型、残留型4个亚组间血清S100B浓度的差异有统计学意义(F=4.63,P=0.006),残留型组明显高于偏执型组(P=0.001)、瓦解型组(P=0.012);且各亚型组均明显高于对照组(P<0.001).③患者组血清S100B浓度与年龄、总病程、PANSS总分及其阴性症状因子分相关(r为0.36、0.46、0.42、-0.38,P均小于0.005).结论 首发未服药的精神分裂症患者血清S100B浓度升高,并与某些病理症状尤其是阴性症状关联,在一定程度上可反映疾病严重程度.
