摘要

摘要: 目的探讨缺血性脑白质病变患者(white matter ischemic lesions, WMIL)患者血清S-100β蛋白的表达及其与WMIL的关系。方法选取2017年6月—2019年9月安徽医科大学附属宿州医院收治的经颅脑磁共振证实的WMIL患者为研究对象，依据Fazekas评定量表评定脑白质病变程度。选取同期年龄和性别相匹配的颅脑磁共振正常者为对照组(69例)。应用酶联免疫吸附法测定患者血清S-100β蛋白水平。比较2组患者临床资料和S-100β蛋白水平，分析血清S-100β蛋白与脑白质病变程度的关系及WMIL的影响因素。结果与对照组比较，WMIL组患者高血压比例(79.1% vs.42.0%)、糖尿病患者比例(34.8% vs.15.9%)、S-100β蛋白水平[(1.414±0.260) pg/mL vs.(0.961±0.316)pg/mL]显著高于对照组，差异均具有统计学意义(均P＜0.05)。WMIL组患者血清S-100β蛋白水平与Fazekas评分呈显著正相关(r=0.736，P＜0.001)。多因素logistic回归分析显示，高血压、糖尿病和S-100β蛋白水平升高是WMIL的独立危险因素(均P＜0.01)。结论血清S-100β蛋白在WMIL患者中表达水平升高，且与WMIL严重程度呈正相关，血清S-100β蛋白水平升高可能是WMIL的独立危险因素，其可能作为脑白质慢性损伤的生物学指标。

Abstract: Objective To explore the expression level of serum S-100β protein in patients with white matter ischaemic lesions (WMIL) and its relationship with WMIL. Methods Patients with WMIL, as confirmed by craniocerebral magnetic resonance, from June 2017 to September 2019 were selected as the research subjects, and the degree of white matter lesions was evaluated on the basis of the Fazekas rating scale. Those with normal craniocerebral magnetic resonance matched with age and sex during the same period were selected as the control group. Serum S-100β protein concentrations were detected with enzyme-linked immunosorbent assays. The general clinical data and S-100β protein levels were compared between the two groups. Spearman rank correlation was used to analyse the relationship between the serum S-100β protein level and degree of white matter lesions, and multivariate Logistic regression was used to analyse the influencing factors of WMIL. Results Compared with the control group, the proportion of patients with hypertension (79.1% vs. 42.0%, P < 0.001), the proportion of patients with diabetes (34.8% vs. 15.9%, P=0.006) and the level of S-100β protein [(1.414±0.260) pg/mL vs. (0.961±0.316) pg/mL, P < 0.001] in the WMIL group were significantly higher, and the differences were statistically significant. The serum S-100β protein level of patients in WMIL group was significantly and positively correlated with the Fazekas score (r=0.736, P < 0.001). Multivariate logistic regression analysis showed that hypertension, diabetes and elevated S-100β protein levels were independent risk factors for WMIL (all P < 0.01). Conclusion The expression level of serum S-100β protein is increased in WMIL patients and positively correlated with the severity of WMIL. The elevated serum S-100β protein level might be an independent risk factor for WMIL, which might be an effective biological marker of chronic white matter damage.
