Objective: To investigate the prevalence and influencing factors of dyslipidemia among adult residents in Hefei City, so as to provide the evidence for formulating the dyslipidemia control strategy. Methods: A total of 10 812 permanent residents at ages of 18 years were randomly sampled from 5 counties (districts) in Hefei City using a multi-stage stratified cluster random sampling method. Participants' demographic features, dietary behaviors and development of chronic diseases were collected using questionnaire surveys, and the height, body weight, waist circumference and blood lipids were measured. The prevalence of dyslipidemia was analyzed, and the factors affecting the development of dyslipidemia were identified using a multivariable logistic regression model. Results: Totally 10 812 valid questionnaires were recovered, with an effective recovery rate of 92.02%. The participants had a male to female ratio of 0.85∶1, a mean age of (51.89±12.56) years. The prevalence of dyslipidemia was 25.20%, and hypertriglyceridemia and low high-density lipoprotein cholesterol (HDL-C) were predominant types of dyslipidemia, with prevalence of 12.70% and 10.20%, respectively. Multivariable logistic regression analysis showed that urban areas (OR=1.340, 95%CI: 1.219-1.474), age of 40 years and older (40 to 59 years, OR=1.181, 95%CI: 1.047-1.333; 60 to 88 years, OR=1.321, 95%CI: 1.154-1.513), alcohol consumption (OR=1.205, 95%CI: 1.093-1.329), insufficient physical activity (OR=1.217, 95%CI: 1.111-1.332), static behavior duration of 3 h/d and longer (OR=1.126, 95%CI: 1.027-1.234), overweight (OR=1.162, 95%CI: 1.045-1.291), obesity (OR=1.310, 95%CI: 1.097-1.564), central pre-obesity (OR=1.236, 95%CI: 1.102-1.387), central obesity (OR=1.414, 95%CI: 1.247-1.603), hypertension (OR=1.279, 95%CI: 1.107-1.477), diabetes (OR=2.192, 95%CI: 1.820-2.640), medical insurance (OR=0.594, 95%CI: 0.395-0.893) and self-rated “very good/good” oral health (OR=0.731, 95%CI: 0.576-0.927) were factors affecting the development of dyslipidemia. Conclusion The risk of dyslipidemia is high among adult residents living in urban areas, middle-aged and elderly residents, residents with alcohol consumption, insufficient physical activity, overweight, obesity, central pre-obesity, central obesity, hypertension and diabetes.

Objective To investigate the bone metabolism of children with leukemia and its relationship to tumor necrosis factor-?(TNF-?)pre-and post-treatment.Methods Serum bone gla protein(BGP),the excretion rate of urianry deoxypyridinoline(DPD)and TNF-? were measured in 35 children with leucocythemia pre-and post-treatment and 30 normal children(control group).Results The results showed that BGP,the excretion rate of DPD and TNF-? in children with leucocythemia before treatment were significantly higher than those in control group.However,the excretion rate of DPD decreased after chemotherapy but still significantly higher than that of control group(P0.05).Conclusions In children with leukemia,there are bone absorption and bone dissolution before chemotherapy,while there is osteogenesis dysfunction and bone absorption after chemotherapy.TNF-? can be used as a parametre for evaluating treatment effect and monitoring relapse.

Objective To investigate the expressions of microRNA-21 in cholangiocarcinoma tissues and the relationship between epithelial-mesenchymal transition (EMT) and the prognosis of patients.Methods Forty-one samples of cholangiocarcinoma and 10 samples of adjacent tissues from 10 patients who received radical resection of cholangiocarcinoma at the Provincial Hospital of Anhui Medical University from January 2005 to January 2010 were collected.The expressions of microRNA-21,E-cadherin and N-cadherin were detected by in situ hybridization and immunohistochemistry,and effect of their expressions on the prognosis was analyzed.Enumeration data were analyzed using chi-square test.The correlation between microRNA-21 and EMT markers was analyzed using the Spearman correlation coefficient.The survival curve was drawn by Kaplan-Meier method,and the survival rate was analyzed using the Log-rank test.Results The expression rate of microRNA-21 in the cholangiocarcinoma tissues was 63％,which was significantly higher than 30％ of that in the adjacent tissues (x2 =0.324,P ＜ 0.05).The expression of microRNA-21 was closely related with the tumor differentiation degree,lymph node metastasis,perineural invasion (x2 =6.365,0.552,11.896,P ＜ 0.05),but not with gender,age,tunor location and tumor type (x2 =0.322,0.588,0.510,0.256,P ＞ 0.05).The expressions of E-cadherin and N-cadherin were related with lymph node metastasis and perineural invasion (x2 =4.630,5.512;6.600,7.152,P ＜0.05),but not with gender,age,tumor location,tumor differentiation degree and tumor type (x2 =0.266,0.013,0.067,0.666,0.003; 1.036,0.997,1.808,2.997,0.812,P ＞0.05).A positive correlation between the expression of microRNA-21 and EMT related markers E-cadherin and N-cadherin was detected (r =0.373,0.614,P ＜0.05).The results of survival analysis showed that the overall survival rate and tumor-free survival rate of patients with low expression of microRNA-21 were significantly higher than those of high expression of microRNA-21 (x2 =3.999,4.376,P ＜ 0.05).Conclusion Over expression of microRNA-21 in cholangiocarcinoma and metastatic lymph nodes may accelerate the invasion and metastasis of cholangiocarcinoma through inducing EMT,microRNA-21 might predict the prognosis of patients.

Objective To observe the changes of lung parameters,the ratios of B and T lymphocyte attenuator(BTLA) and serum cytokines in patients with knee osteoarthritis (KOA),and explore possible molecular mechanism of them.Methods Forty-seven cases of knee osteoarthritis from the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine from 2011 October to 2012 July were analyzed in this study.Pulmonary parameters were detected by spirometer; B and T lymphocyte attenuator(BTLA) was detected by flow cytometry ; Interleukin (IL)-1β,IL-10,matrix metalloproteinase-9 (MMP-9),tissue inhibitor of matrix metalloprotease-1 (TIMP-1) were detected by ELISA;ESR was determined by Westergren method ; hs-CRP was determined by the automatic biochemistry analyzer.Results (1) Compared with NC group,levels of FVC,FEV1,FEV1/FVC,PEF,MEF25.75,MEF50,MEF25,CD3 + BTLA+ T cell,CD4+ BTLA+ Tcell,IL-10,TIMP1 were significantly decreased,IL-1 β,MMP9 were significantly increased.(2)Correlation analysis showed FVC was negatively correlated to Lequesne MG,symptom classify quantization scores,course,MMP9,while positively related to CD3+ BTLA+T cell,IL-10,TIMP1 ;FEV1 was positively correlated to CD3 + BTLA+T cell,CD4+ BTLA+T cell,TIMP1,while negatively correlated to course ; MEF50 was positively related to CD3+BTLA+T cell,CD4+ BTLA+T cell.Conclusion While articular cartilage lesions occurred in KOA patients,the lung function was also declined.The mechanism may be associated with the declination of expression of BTLA,which can cause up-regulating of IL-1 β,MMP9 and down-regulating of IL-10,TIMP1,thus leading to immune dysfunction and abnormal immune response.Those may induce airway injuries and result in lung function decline finally.

Objective To investigate the distribution of Human Papillomavirus 16 (HPV16) infection and its mixed infection with other HPV subtypes in the Yunnan region. Methods 16 166 cases of women were tested using flow fluorescence Luminex technology. Results (1) HPV16 infection rate and mixed infection rate was 2.2%and 28.0%, respectively; (2) The most common type of HPV16 mixed infection was HPV52, followed by HPV33. The two kinds of mixed infection accounted for 39.8% of the total infection rate; (3) There was a significant difference between each age group of HPV16 mixed infection (Chi=26.39, <0.01) . Conclusion The HPV16 infection was mainly HPV infection in Yunnan region. HPV16 mixed infection merged mainly with HPV52 and HPV33. HPV16 mixed infection was associated with age.

PNS (Panax notoginseng saponins) is the main medical bioactive component in Panax notoginseng. The medical value of PNS cannot be extended because of its low production. With the deep study of saponins biosynthetic pathway, the control of PNS biosynthesis through metabolic engineering has gradually become possible. In this study, the Squalene synthase (SS) over-expression vector was established. By the way of agrobacterium-mediated method, the vector was transfered and integrated into the Panax notoginseng genome. The result of the PCR detection and the saponin content detection shows that over-expression SS is able to produce high level of Panax notoginseng saponins, and confirms the regulatory function of SS in the biosynthesis of ginsenosides in Panax notoginseng. It provides a theoretical basis and technical basis for the construction of PNS homologous or heterologous efficient expression system in the future.
