Objective To analysis the relationship between of waist-to-height ratio(WHtR) and the non-alcoholic fatty liver disease(NAFLD).Methods A total of 7 896 were selected as observed subjects from the Kailuan Group in 2011-2012 health physical examination.A questionnaire survey,blood biochemical and abdominal ultrasound examination were finished by trained medical staff.According to previous study recommended cut points the observed subjects was divided into two groups:abdominnal obesity group(WHtR≥0.5,n=3 185) and non-abdominnal obesity group(WHtR<0.5,n=479).According to the WHtR and its quartile,the observed subjects was divided into four groups(first(WHtR<0.47),second(0.47≤WHtR<0.51),third(0.51≤WHtR<0.55) and forth(WHtR≥0.55) quartile groups).NAFLD detection rate of the four groups were Compared.Multiple Logistic regression analysis was used to analyze the influencing factors of the NAFLD.Results (1)The detection rate of NAFLD in abdominnal obesity group was higher than that in non-obesity group(62.7% vs.21.5%,P<0.01).Along with increasing WHtR level in the 4 quartile groups,the incidence of NAFLD was progressively increased,being 12.6 %,38.1%,57.5% and 72.5% respectively in the total population.After stratified by gender,15.1%,40.6%,59.6% and 75.0% in male,7.8%,31.5%,48.3% and 63.8% in female.In the same WHtR group,the NAFLD detection rate of male was higher than female,the differences were statistically significant(P<0.01).(2)Multiple logistic regression analysis showed that compared with the first quartile group,the second,third and forth quartile groups had increased risk of NAFLD after adjusting age,gender and other risk factors,the OR value being 3.19,5.93 and 9.81 in the total population.After adjusting above factors,the OR value being 3.12,6.02 and 10.45 in male,3.32,5.37 and 7.57 in female,respectively.Conclusion The incidence of NAFLD is increased along with the increasing the WHtR.

Objective To investigate the effects of waist-to-hip ratio (WHR) on the formation of carotid plaque in the middle-aged and elderly people.Methods A total of five thousand and ninety-nine participants who have taken physical examination in Tangshan Kailuan Company from June 2010 to October 2011(above 40 years old,no previous history of ischemic stroke,transient ischemic attack,myocardial infarction) were enrolled in this study.Questionnaire survey,blood biochemical and carotid artery ultrasound examination were used to examine the subjects.According to WHR,quartile division was used to divide the subjects into four groups.The detection rates of carotid plaque among the 4 groups were compared.Multivariate logistic regression analysis was used to analyze the factors effecting carotid artery plaques.Results (1) The detection rate of carotid artery plaque increased with the increase of WHR,the rates of the first,second,third and fourth group were 20.7% (571/2 753),21.9% (604/2 753),27.5% (758/2 753) and 29.8% (820/2 753) respectively.The difference was statistically significant(P=0.000).(2) Logistic regression model was used to analyze multiple factors affecting the detection rate of carotid plaque.After the correction of other factors,compared with the first group,the carotid artery plaque detection rate in the second,third,fourth group were all increased,the OR values were 1.23(95%CI:1.10~1.54),1.65(95%CI:1.52~2.13),1.67(95%CI:1.54~2.17),respectively.Conclusion The increased WHR in the middle-aged and elderly population may increase the risk of carotid plaque formation.

Objective:To investigate the differences in the expression of microRNA (miR)-216a and its target gene SerpinB5 at the tissue level, and the effects of miR-216a on the proliferation of different liver cancer cells by regulating the expression of SerpinB5.Methods:Through bioinformatics prediction and selection of miR-216a that regulated SerpinB5. the expressions in liver cancer and normal tissues were detected by real time polymerase chain reaction (PCR). The miR-216a simulacrum and inhibitor, si-Serpinb5 and pcdna3.1-Serpinb5 to HepG2 and MHCC97H (97H) were transfected with liposomes, respectively. Real time PCR and Wester-Blot were used to detect the expression of miR-216a and SerpinB5 before and after transfection, and CCK8 was used to detect the influence of both on the proliferation of liver cancer cells.Results:The expression of miR-216a in human liver cancer tissues was higher than that in adjacent tissues, and the difference was statistically significant ( P < 0.01). The expression of SerpinB5 in human liver cancer tissues was lower than that adjacent tissues, and the difference was statistically significant ( P < 0.01). In HepG2 and 97H, miR-216a inhibitor and SerpinB5 overexpression group showed down-regulated miR-216a expression, which was statistically different from the control group ( P < 0.01). The proliferation of miR-216a inhibitor and pcdna3.1-serpinb5 group was lower than the control group, with statistically significant differences ( P < 0.01). Conclusions:The high expression of SerpinB5 can inhibit the proliferation of liver cancer cells, suggesting that SerpinB5 may have an anti-oncogene effect. MiR-216a may negatively regulate the expression of SerpinB5 and affect the proliferation of HCC cells.
