宁夏地区回族、汉族牙周炎患者血脂水平的分析

目的：探讨宁夏地区回族、汉族牙周炎与血脂水平的关系及民族间的差异。方法：对50例回民牙周炎患者（A组）、50例回民牙周健康者（AH组）、60例汉民牙周炎患者（B组）及60例汉民牙周健康者（BH组）抽取空腹静脉血检测甘油三酯（TG）、总胆固醇（CHOL）、高密度脂蛋白胆固醇（HDL-C）和低密度脂蛋白胆固醇（LDL-C）的含量并进行牙周检查。在校正了性别、年龄、吸烟、体重指数、血糖等影响因素后比较两民族牙周炎患者和牙周健康者之间血脂水平的差异。结果：A组中CHOL（4.55±1.05）mmol/L和LDL-C（2.77±0.69）mmol/L的含量高于AH组中CHOL（3.99±1.05）mmol/L和LDL-C（2.23±0.78）mmol/L的含量（P〈0.05）;B组中CHOL（4.40±1.00）mmol/L和LDL-C（2.87±0.71）mmol/L的含量高于BH组中CHOL（3.80±1.06）mmol/L和LDL-C（2.35±0.93）mmol/L的含量（P〈0.05）;A组和B组,AH组和BH组间各项指标差异无显著性。结论：宁夏地区回族和汉族牙周炎可能影响血脂中CHOL和LDL-C的水平但民族间无差异性。

Blood Lipids Levels of Hui and Han Patients with Periodontitis in Ningxia

Objective：To determine the serum levels of lipids and the national difference in Hui and Han patients with periodontitis in Ningxia.Methods：The Hui patients with periodontitis（group A,n=50）,Hui healthy controls（group AH,n=50）,Han patients with periodontitis（group B,n=60）and Han healthy controls（group BH,n=60）were recruited.Peripheral blood sample was obtained from each subjected by venipuncture and periodontal conditions were also obtained from each person.Serum chemistry variables included triglyceride（TG）,total cholesterol（CHOL）,high density lipoprotein cholesterol（HDL-C）and low density lipoprotein cholesterol（LDL-C）.The serum levels of lipids were compared between group A and group AH,group B and group BH,group A and group B,group AH and group BH,controlling for those related factors including gender,age,smoking,body mass index,blood sugar and blood pressure.Results：No matter Hui or Han nationality,the CHOL and LDL-C levels of patients were significantly higher than that of healthy controls.As for other variables,there were no differences between four groups.Conclusion：Hui and Han patients with periodontitis may have altered serum lipids levels compared with controls,but there is no difference between two nationalities.
