Objective The article aimed to investigate the correlation of lipid profile levels with deoxyribonucleic acid (DNA) damage and total antioxidant capacity (TAC) levels in obese pregnant women. Methods Healthy pregnant women (n=120 ) who took routine prenatal care from August 2011 to August 2012 in our hospital were recruited .All the pregnant women were di-vided into normal weight group ( n =45 ) and obese group ( n=75 ) .The lipid profile levels , DNA damage and TAC levels of two groups were compared and analyzed , and the correlations among lipid profile levels , DNA damage and TAC levels were analyzed . Results Compared to normal weight group , obese group showed significantly higher levels of TC (P=0.000), TG(P=0.000), and LDL-c(P=0.004), but a lower level of HDL-c (P=0.006).The DNA damage and TAC level of obese group were obviously higher than those of normal weight group (P=0.000, P=0.000).The DNA damage was positively correlated with levels of TC , TG and LDL-c among obese pregnant women (r=0.23, P=0.026;r=0.26, P=0.008;r=0.19, P=0.032), and TAC level was positive-ly correlated with TG level (r=0.32,P=0.000). Conclusion Dyslipidemia, imbalance of prooxidant and antioxidant status al-ways occur to obese pregnant women .The DNA damage is positively correlated with levels of TC , TG and LDL-c among obese pregnant women, and TAC is positively correlated with TG level .

Objective To determine the incidence rate of HPV infection or multi-infections at different stages of cervical lesions in the development of cervical cancer , and the impact of specific types of HPV multi-infections on the risk of cervical cancer. Methods 103 samples of cervical tissues were detected and then divid-ed into ICC/HSIL group and LSIL/NILMF group according to the degree of pathological changes. HPV type was determined by PCR product sequencing. E6 nested multiplex PCR was performed to detect HPV multi-infections. Odds ratios were calculated to determinate the association between the sample category (LSIL/NILM or ICC/HSIL) and the specific types of HPV multi-infections. Results In HPV-positive samples, the rate of multi-in-fections had no significant differences between the two groups. Coinfection of HPV68 with HPV16 increased the risk of ICC/HSIL, as compared with HPV16 or HPV68 infection alone. Conclusions High-risk HPV coinfec-tions has a higher risk to induce ICC/HSIL than does HPV infection alone.
