摘要:目的:探讨血清胱抑素C(cystatin C,Cys C)与急性脑梗死预后的相关性。方法:回顾性分析66例急性脑梗死患者的临床资料,依据改良Rankin量表(mRS)对所有纳入患者进行神经功能评分,并分为预后良好(mRS评分≤2分)组33例和预后不良(mRS评分>2分)组33例。采用Logistic回归分析确定急性脑梗死患者预后不良因素,分析不同严重程度脑梗死患者血清Cys C水平,采用受试者工作特征曲线评价入院时患者血清Cys C水平对急性脑梗死预后的预测价值。结果:预后不良组心房颤动和脑梗死发生率高于预后良好组。预后不良组血清Cys C水平、NIHSS评分较预后良好组高。入院时血清Cys C水平与卒中严重程度呈正相关。结论:入院时血清Cys C水平对急性脑梗死患者预后有良好的预测价值,高血清Cys C水平提示预后不良。

Correlation between serum cystatin C and acute cerebral infarction and short-term prognosis

OBJECTIVE: To investigate the relationship between serum cystatin C (Cys C) and prognosis of acute cerebral infarction. Methods: The clinical data of 66 patients with acute cerebral infarction were retrospectively analyzed.The neurological scores of all included patients were scored according to the modified Rankin scale (mRS), and the prognosis was good (mRS score ≤ 2 points). There were 33 patients with poor prognosis (mRS score > 2 points) in 33 patients.The prognostic factors of patients with acute cerebral infarction were determined by logistic regression analysis. The serum Cys C levels of patients with different severity of cerebral infarction were analyzed. The receiver operating characteristic curve was used to evaluate the serum Cys C level of patients. Predictive value of prognosis for acute cerebral infarction. RESULTS: The incidence of atrial fibrillation and cerebral infarction was higher than that of the prognosis group. Serum CysC levels and NIHSS scores were higher in the poor prognosis group than in the prognosis group. Serum Cys C levels were positively correlated with stroke severity at admission. Multivariate logistic regression analysis showed that NIHSS score, serum Cys C level, and history of atrial fibrillation at admission were independent risk factors for poor prognosis.Conclusion: Serum Cys C level at admission has a good predictive value for the prognosis of patients with acute cerebral infarction. High serum Cys C levels suggest a poor prognosis.

前言:脑梗是死亡的重要病因,病发因素种类众多,人群基数大,高危人群比例高,需更加积极地防治脑梗[1]。胱抑素C (Cys C)主要功能是抑制内源性蛋白半胱氨酸的活性,近年来许多国内外学者发现Cys C会促进动脉粥样硬化的发生,与缺血性脑梗发生发展密切相关,且血清Cys C水平增高与亚临床脑梗死也存在相关性[2]。目前,研究血清Cys C水平与预后水平的报告较少,本研究旨在探讨血清Cys C与急性脑梗死预后相关性及对预后的价值。

1.资料与方法

1.1临床资料

收集近两年神经内科住院的AIS患者66例。依据国际急性卒中TOAST分型标准进行分类,其中大动脉粥样硬型脑梗死(LAA)40例,小血管闭塞型脑梗死(SAA)18例,心源性脑栓塞型(CE)6例,其他原因型(SOE)1例,不明原因型(SUE)1例。

1.2基本方法

入院后根据NIHSS评分对所有AIS患者进行神经功能缺损评分。对出院3个月后患者根据改良Rankin量表(mRS)进行神经功能评分并分为两组,mRS≤2分为预后良好组38例,mRS>2分为预后不良组29例。两组性别,吸烟、饮酒、高血压、糖尿病、高脂血症史,TOAST分型差异均无统计学意义(P>0.05),预后不良组年龄较预后良好组大、心房颤动和脑梗死发生率均高于预后良好组(P<0.05)。

1.3观察指标

统计患者的年龄、性别、发病到入院时间、入院时NIHSS评分、以往病史(糖尿病、高血压病、高脂血症、心房颤动、脑梗死)、吸烟史、饮酒史。观察患者部分血生检验结果[Cys C、空腹血糖、肌酐、TG、TC、LDL-C、高密度脂蛋白胆固醇(HDL-C)]。

1.4统计方法

应用SPSS 19.0软件处理数据。正态分布的计量资料比较采用t检验,非正态分布的计量资料比较采用秩和检验;计数资料比较采用x²检验;相关性采用Spearman相关分析;多因素分析采用Logistic回归分析;用受试者工作特征(ROC)曲线评价入院时Cys C水平及Cys C水平对AIS患者预后不良的敏感性和特异度,计算Youden指数,确定最佳诊断界值。P<0.05为差异有统计学意义。

2.结果

Cys C水平判断预后的敏感度、特异度和准确度入院时Cys C水平ROC曲线下面积为0.708(0.646~0.771),当Cys C =0.97时,Youden指数最大为0.325,其敏感度为65.8%,特异度为66.7%,准确度66.0%,见表。

3.结论

结果显示,与正常对照组比较急性脑梗死组患者的血清Cys-C水平明显升高,说明Cys-C为急性脑梗死的危险因素,同大多数研究结论一致[3],与疾病发生、病情轻重、近期预后紧密联系,监测血清Cys-C水平变化并进行及时、必要干预,对预防疾病发生、了解病情轻重、改善患者预后将具有重要意义。
