Abstract:
Objective To investigate expression of glutathione S-transferase(GST) mRNA in peripheral blood of the population in coal-burning fluorosis area and to evaluate the effect of comprehensive control intervention. Methods Fifty samples of peripheral blood from patients in the coal-buring fluorosis area in Bijie county of Guizhou province were selected as fluorasis group and 50 samples of peripheral blood from patients in area with comprehensive management were selected as intervention group, respectively. Fifty samples from non-endemic fluorosis area were selected as the control group. Total RNA from blood was extracted and purified by the Trizol- Phenol-Chloroform one-step method. Expression of GST mRNA was detected by using SYBR Green I real-time fluorescence quantitative PCR. Results The data of GST mRNA in fluorosis group, intervention group and control group was 38.28±27.22,70.56±37.23 and 103.46 ± 46.62, respectively. There was a significant difference between the groups(F = 3.75, P < 0.05). Decreased expression of GST mRNA in fluorosis group and intervention group as compare to control was detected(all P < 0.05), and the expression of GST mRNA in intervention group was higher than that in fluorosis group(P < 0.05). Conclusion Coal-burning fluorosis possibly led to the decreased expression of GST mRNA in peripheral blood, and comprehensive control maybe prevent the decreased expression of GST in mRNA level.
