ABSTRACT
Objective To investigate the association between plasma Klotho protein level and lacunar cerebral infarction in the elderly.Methods Eighty eight patients with lacunar cerebral infarction aged over 60 years were selected as the observation group,and 90 age-and gender-matched elderly patients without lacunar infarction as the control group.The protein level of Klotho was tested by enzyme linked immunosorbent assay (ELISA).Klotho protein level was compared between the observation and control groups.The correlation between plasma Klotho level and lacunar infarction in elderly patients was analyzed.Results Compared with the control group,lacunar infarction group showed that Klotho protein level was decreased [(689.4±40.8) ng/L vs.(848.5±38.7) ng/L,P=0.009],and the proportion of patients with hypertension was increased (83.0％ vs.66.7％,P=0.04).There was no significant difference in age,gender,body mass index (BMI),dyslipidemia,diabetes mellitus and coronary heart disease between the two groups.The multivariate logistic regression analysis showed that the low plasma level of Klotho protein and hypertension were identified as the independent risk factors for Lacunar infarction (OR=3.325 and 2.413,P=0.003 and 0.021,respectively).Conclusions Klotho protein level may be associated with lacunar cerebral infarction in elderly people.Monitoring plasma Klotho protein level has an important clinical significance in the prevention,diagnosis and prognosis of lacunar cerebral infarction.
ABSTRACT
Objective To explore the correlation between plasma Klotho and FGF23 levels with senile hypertension .Methods Totally 180 cases of hypertension aged more than 60 years old were selected as the research group and divided into the grade 1 hypertension group(60 cases) ,grade 2 hypertension group(60 cases) and grade 3 hypertension group(60 cases) .The age and pro‐portion of male to female were basically consistent .60 elderly people without hypertension were selected as the control group .The level of plasma Klotho and FGF23 protein were tested by ELISA .The lipid level was detected by the automatic biochemical analy‐zer .The detection results were compared with those in the control group for analyzing their correlation .Results Plasma Klotho protein level in each hypertension group was lower than that in the control group ,while plasma FGF23 protein level and BMI were significantly higher than those in the control group(P0 .05) .Conclusion Plasma Klotho protein and FGF23 protein levels have obvious correlation with the blood pressure level ,which may jointly participate in the occurrence and development of hypertension .
