Correlation analyses of serum levels of homocysteine and hypersensitivity C-reactive protein in elderly patients with cerebral infarction / 中国医师杂志

ABSTRACT

Objective To observe the serum levels of homocysteine (Hcy) and hypersensitivity C-reactive protein(hs-CRP) in elderly patients with cerebral infarction and to investigate their relationship and clinical significance by National Institutes of Health Stroke Scale (NIHSS).Methods The serum levels of Hcy and hs-CRP were by enzymatic cycling method and scattering turbidimetry in the elderly patients ( 116 cases with cerebral infarction and 100 cases of healthy control).Those 116 cases with cerebral infarction were divided into three groups by the degree of NIHSS.The three groups were compared with each other.Results The levels of serum Hcy and hs-CRP in elderly patients with cerebral infarction were significantly higher than that of healthy control group ( t =6.97,P ＜0.01 ; t =14.96,P ＜0.01 ).There has significant difference among those three groups with cerebral infarction by comparing with each other( F =23.49,P ＜0.05; F =28.19,P ＜0.05).A positive correlation was found between Hcy and degree of NIHSS( r=0.54,P ＜0.05),and between hs-CRPand degree of NIHSS( r =0.58,P ＜0.05).Conclusions Serum levels of Hcy and hs-CRP are correlated with the occurrence of cerebral infarction and its severity.There has positive clinical significance to evaluate the effect of cerebral infarction by measuring the serum levels of Hcy and hs-CRP dynamic.
