ABSTRACT
Objective To investigate the relationship between single nucleotide polymorphism(SNP)of the peroxisome proliferator activated receptor γ (PPARγ) gene Rs1801282 and brick-tea type fluorosis. Methods From 2012 to 2013, this cross-sectional study was performed in 16 endemic fluorosis areas of brick-tea type in Inner Mongolia Autonomous Region,Qinghai and Xinjiang Uygur Autonomous Region of China,to select adults>18 years old as subjects, who were diagnosed as skeletal fluorosis by X-ray. All of the subjects filled in demography survey questionnaire; the survey contents included general characteristic s, and average daily brick tea intake. Drinking tea samples and urine samples of each subject were collected, and fluoride content of urine and brick-tea was determined via the ion selective electrode method (WS/T 89-2006). X-ray scintigraphy was used to diagnose skeletal fluorosis, according to the "Diagnostic Criteria of Endemic Skeletal Fluorosis" (WS/T 192-2007); the subjects were divided into skeletal fluorosis group (case group) and non-skeletal fluorosis group (control group). To collect venous blood 5 ml, whole blood DNA was extracted, and polymorphism at Rs1801282 of PPARγ was detected by MassARRAY time-of-flight mass spectrometry, to calculate odds ratio (OR) and 95% confidence interval (CI). Results There were 1 414 people included in this study,including 347 in case group and 1 067 in control group. By the Hardy-Weinberg balance test, the PPARγ gene Rs1801282 genotype was representative in case group, control group and each nationality (P > 0.05). The difference of PPARγ gene Rs1801282 genotype in case group and control group was not statistically significant (OR was 0.991, 95%CI: 0.704 - 1.395, the adjusted OR was 1.026, 95%CI: 0.707-1.489).The difference of PPARγ gene Rs1801282 genotype(CC,CG+GG)in case group and control group in different nationality was not statistically significant (Tibetan: OR was 1.400, 95%CI: 0.576 - 3.404, the adjusted OR was 1.258, 95%CI: 0.474 - 3.340; Kazak: OR was 0.898, 95%CI:0.516 -1.562,the adjusted OR was 0.936,95%CI:0.532 -1.648;Mongolia: OR was 1.148,95%CI:0.508-2.594, the adjusted OR was 1.644, 95%CI: 0.683 - 3.956; Han: OR was 1.058, 95%CI: 0.451 - 2.482, the adjusted OR was 0.959, 95%CI: 0.388 - 2.371; Russian: OR was 0.000, 95%CI: 0.000 - 0.000, the adjusted OR was 0.000, 95% CI: 0.000 - 0.000) with binary Logistic regression analysis. Conclusion We have found no association between SNP of PPARγ gene Rs1801282 and skeletal fluorosis of brick-tea type fluorosis in China.
