Plasma resistin level and its correlation in patients with essential hypertension of Kazakans and Han nationalities / 中国医师杂志

ABSTRACT

Objective To observe plasma resistin levels in patients with essential hypertension (HT) of Xinjiang Kazakans and Han nationalities, and explore its association with insulin resistance (IR), blood glucose, blood lipids, blood pressure and obesity. Methods Total 127 Kazakan cases and 131 Han cases were selected as the subjects. According to their blood pressure, they were divided into HT group of Kazakans, control group of Kazakans, HT group of Hans and control group of Hans. Blood pressure, height, weight, waist circum-ference (WC) and hip were measured. Plasma resistin, fasting insulin(FINS), fasting plasma glucose (FPG), total cholesterol (TC), tri-glyceride (TG), high-density lipoprotein cholesterol ( HDL-C), low-density lipoprotein cholesterol ( LDL-C), apoprotein-A1( Apo-A1)and apoprotein-B(Apo-B) were determined. Body mass index (BMI), waist-hip ratio ( WHR), body fat percentage ( BF% )and homeostasis model assessment of insulin resistance index ( HOMA-IR) were calculated. Results Plasma resistin levels in the HT groups of Kazakans and Hans were significantly higher than those in their control groups ( P<0.01 ). There were no significant difference in the comparison of plasma resistin levels in HT groups or control groups between Kazakans and Hans ( P>0.05). Plasma resistin was posi-tively and significandy correlated with age, systolic blood pressure (SBP), WC, BMI, WHR, BF%, FlaG, FINS, HOMA-IR, TG in HT groups of Kazakans and Hans ( HT group of Kazakans, r=0.492,0.296,0.281,0.648,0.263,0.515,0.742,0.759,0.797,0.595; HT group of Hans, r=0.417,0.275,0.391,0.483,0.278,0.318,0.453,0.560,0.641,0.310; P<0.05). After the influential factors such as age, blood glucose, blood lipids and obesity were adjusted, plasma resistin level in four groups were still positively and significantly corre-lated with FINS and HOMA-IR ( HT group of Kazakans, r=0.432,0.410 ; control group of Kazakans, r=0.327,0.305 ; HT group of Hans, r=0.426,0.425 ; control group of Hans, r=0.377,0.392 ; P<0.05), but not correlated with SBP or DBP( P>0.05 ). HOMA-IR, FPG and BMI were independent factors for plasma resistin level in HT group of Kazakans, while HOMA-IR, FlaG and BF% were inde-pendent factors for plasma resistin level in HT group of Hans. Conclusion Plasma resistin level was increased in patients with HT of Kaza-karts and Hans. Close correlations between resistin and obesity, blood glucose and IR were found, and there may be indirect correlation be-tween resistin and blood pressure.
