哈萨克族与汉族高血压病患者血浆抵抗素水平的相关性研究

目的观察新疆哈萨克族（哈族）、汉族高血压病（HT）患者血浆抵抗素水平及其与胰岛素抵抗（IR）、血糖、血脂、血压及肥胖指标的关系。方法选取新疆哈族人127例及汉族人131例作为研究对象。根据血压水平，分为哈族HT组、哈族对照组、汉族HT组、汉族对照组。均测量血压、身高、体重、腰围（WC）及臀围，抽取空腹静脉血，检测血浆抵抗素、胰岛素（FINS）、血糖（FPG）、总胆固醇（TC）、甘油三酯（TG）、高密度脂蛋白胆固醇（HDL—C）、低密度脂蛋白胆固醇（LDL—C）、载脂蛋白AI（Apo—AI）、载脂蛋白B（Apo—B）。计算体重指数（BMI）、腰臀比（WHR）、体内脂肪百分比（BF％）、HOMA-胰岛素抵抗指数（HOMA-IR）等进行比较。结果哈、汉HT组血浆抵抗素水平均明显高于相应的对照组（P〈0．01）；哈、汉HT组间或哈、汉对照组间血浆抵抗素水平差异无统计学意义（P〉0．05）；在哈、汉HT组，抵抗素均与年龄、SBP、WC、BMI、WHR、BF％、FPG、FINS、HOMA—IR、TG呈正相关（哈HT组r=0．492，0．296，0．28I＇0．648，0．263，0．515，0．742，0．759，0．797，0．595；汉HT组r=0．417，0．275，0．391，0．483，0．278．O．318，0．453，0．560，0．641，0．310；P〈0．05）；调整年龄、血糖、血脂、肥胖等指标后，各组中抵抗素仍与FINS、HOMA—IR呈正相关（哈HT组r=0．432，0．410；哈对照组r=0．327，0．305；汉HT组r=0．426，0．425；汉对照组r=0．377，0．392；P〈0．05），与SBP、DBP无相关（P〉0．05）；在哈族HT组，HOMA—IR、FPG和BMI是影响血浆抵抗素水平的独立因素；在汉族HT组，HOMA—IR、FPG和BF％是影响血浆抵抗素水平的独立因素。结论哈、汉HT患者血浆抵抗素水平升高，其血浆抵抗素与肥胖、血糖及IR关系密切，与血压可能存在间接关系。

Plasma resistin level and its correlation in patients with essential hypertension of Kazakans and Han nationalities

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.
