目的探讨血清半胱氨酸蛋白酶抑制剂C浓度、血清肌酐浓度对脑梗死发病的影响.方法选择经临床、颅脑CT和(或)MRI确诊的脑梗死患者84例及同期体检正常者76例,酶联免疫法测定血清半胱氨酸蛋白酶抑制剂C浓度,苦味酸法测定肌酐浓度,观察血清半胱氨酸蛋白酶抑制剂C、肌酐与脑梗死发病的关系.结果脑梗死组血清半胱氨酸蛋白酶抑制剂C的浓度[(1.69±0.60)mg/L]明显低于对照组[(2.00±0.67)mg/L],血清肌酐的浓度[(86.62±14.02)μmol/L]明显高于对照组[(80.88±13.71)μmol/L],比较差异均有统计学意义(P＜0.05).相关分析显示血清半胱氨酸蛋白酶抑制剂C与脑梗死呈负相关(r=-0.238,P=0.002),血清肌酐与脑梗死呈正相关(r=0.208,P=0.010).结论血清半胱氨酸蛋白酶抑制剂C、肌酐与脑梗死发病相关,半胱氨酸蛋白酶抑制剂C可能是脑梗死发病的一种保护因素,而肌酐可能是脑梗死发病的一种危险因素.

Objective To investigate the correlation of serum cystatin C and creatinine levels with cerebral infarction. Methods Eighty-four patients with cerebral infarction diagnosed by clinical manifestations, CT and (or) MRI and 76 healthy subjects were selected. Cystatin C level was tested by enzyme-linked immunosorbent assay (ELISA) and creatinine level was tested by the method of nitroxanthic acid. The correlation of cystatin C and creatinine levels with cerebral infarction was explored. Results The level of serum cystatin C in the cerebral infarction group (1.69±0.60 mg/L) was significantly lower as compared with that in the control group (2.00±0.67 mg/L) (t=-3.084, P=0.002); the level of serum creatinine in the cerebral infarction group (86.62±14.02 μmol/L) was significantly higher as compared with that in the control group (80.88±13.71 μmol/L) (t=2.611, P=0.010). Negative correlation between level of serum cystain C and cerebral infarction was noted (r=-0.238, P=0.002),while the level of serum creatinine was positively related to cerebral infarction (r=0.208, P=0.010).Conclusion A close correlation between cerebral infarction and both the levels of cystain C and creatinine exists, with cystatin C being a protective factor and creatinine being a risk factor for clinical cerebral infarction.
