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.

Based on the questionnaire survey and the interview to the court and law offices as well as the analysis of the society's demand for the knowledge structure and ability of medicine law professionals, we proposed the construction of the training mode for medicine law professionals with the ability to adapt to the social demand.

Objective To study clinical features, treatment and prognosis of nasal NK/T cell lymphoma associated Hemophagocytic Syndrome (HPS).Methods Retrospectively analysis method was used to analyze the clinical data of 3 patients with nasal NK/T cell lymphoma associated HPS. Results 3 patients with nasal NK/T cell lymphoma fulfilled the criteria of HPS. All patients had adverse prognostic factors of lymphoma.1 patient developed HPS as the main primary manifestations of underlying lymphoma,the other 2 patients developed HPS during lymphoma progression. In three cases, bone marrow was infiltrated with lymphoma cells.When HPS occurred,the disease progressed rapidly.The most obvious clinical features were fever,pancytopenia,hypofibrinogenemia,hyperferritinemia,and hemophagocytosis in bone marrow. After being treated according to the HLH-2004 combined with chemotherapy, all patients showed a clinical response,but with the progression of lymphoma,HPS quickly relapsed,and all patients died of severe hepatic dysfunction,coagulopathy,or DIC.Conclusion Nasal NK/T lymphoma associated HPS is an invariably fatal disease with poor prognosis,typically occurring at advanced stage or the terminal phase of the disease.HLH-2004 based protocol in combination with chemotherapy is helpful for nasal NK/T cell lymphoma associated HPS,which may delay disease progression and provid opportunities for the treatment of primary disease.

Objective To investigate the clinical features,early diagnosis and individualized treatment of renal hypophosphatemia and osteomalacia induced by adefovir dipivoxil (ADV) in patients with chronic hepatitis B (CHB).Methods Thirty-nine CHB or hepatitis B virus (HBV)-related cirrhosis patients of renal hypophosphatemia and osteomalacia induced by ADV were consecutively collected.The clinical features were analyzed and treatment outcome was followed up.Results The mean age of the 39 patients was 54 (27-71) years old.There were 26 male and 13 female patients,and 19 patients with cirrhosis.The mean ADV treatment duration was 69 (range 18-116) months,and 31 patients were treated for 36-96 months.The mean serum phosphate was 0.68 (0.42-0.79) mmol/L.Twenty-six cases developed renal hypophosphatemic osteomaolacia,of which 14 had bone pain and 19 had abnormally elevated alkaline phosphatase (ALP).Three patients had increased serum creatinine and 24 patients had decreased estimated glomerular filtration rate (eGFR).After individualized treatment,patients gained normal serum phosphate in mean of 2.0 (range 0.5-6.0) months,and had bone pain remission in the mean of 0.8 (range 0.2-1.0) month and bone pain disappeared in the mean of 1.5 (range 0.5-5.0) months.Function indices of liver and kidney were improved gradually,and the bone mineral density examination improved slowly.Conclusions CHB and HBV-related cirrhosis patients treated with longterm ADV could develop renal hypophosphatemia and hypophosphatemic osteomalacia,which is partially reversible.Monitoring serum phosphate,creatinine and cystatin C is necessary during long-term ADV therapy.After confirmed diagnosis,withdrawal or dosage reduction of ADV,and switch to telbivudine or entecavir should be considered.Meanwhile,serum phosphate and HBV DNA level should be monitored.

There were significant increase in urine protein excretion,raised malondialdehyde(MDA) level and expressions of NF-?B,p22phox and p47phox in renal tissue,and significant decrease in reduced glutathione,superoxide dismutase,vitamin C and E levels in type 2 diabetic Goto-Kakisaki rats after 12 weeks. There was obvious histomorphologic change in the kidneys.All the above indices were improved by intraperitoneal injection of?-lipoic acid(35 mg/kg q.o.d).Besides,significant positive correlations were found of MDA level to p22phox,p47phox and NF-?B in the renal tissue,?-lipoic acid seems to protect the diabetic kidney in this diabetic rat model via antioxidative effects.

Two effective flavobacterium strains FCN1 and FCN2 were isolated from the sludge which had been contaminated by coke-plant waste water for a long time.Before isolation,the naphthalene was used to cultivate such sludge for seven weeks as the sole carbon source and its concentration adding to the cultivating system was increased up to 50mg/L gradually.The polycyclic aromatic hydrocarbon degrading characteristics of our isolates themselves and with inorganic ions was studied respectively.The testing results show that our two isolates can transform and degrade anthracene,phenanthrene and pyrene.After 10 hours reaction,the removing rates of anthracene,phenanthrene and pyrene by FCN1 were 84%,69%,80% and by FCN2 were 76%,40%,71% respectively.After 106 hours,the removing rates of TOC caused by anthracene,phenanthrene and pyrene were 70%,54%,69% by FCN1 and 63%,50%,46% by FCN2.The Fe 3+ and Mg 2+ can accelerate the degrading reaction of FCN1.

Objective To investigate the effects of sex hormone-binding globulin (SHBG)gene in the apoptosis of human trophoblastic cells.Methods The siRNA specific-targeting SHBG gene was transfected into human trophoblastic cells and they were divided into six groups:trophoblasts without transfection in normal control groups(group Ⅰ);transfect liposome in blank control groups(group Ⅱ);transfect nonspecific siRNA in negative control groups(group Ⅲ);transfect SHBG siRNA-Ⅰ,SHBG siRNA-Ⅱ,SHBG siRNA-Ⅲ respectively in trans-fection group(group Ⅳ,Ⅴ,Ⅵ).Hoechst 33258 dying method was used to detect cell apoptosis.SHBG and Caspase-3 mRNA profiling and the level of SHBG and caspase-3 protein were detected by real-time PCR and Western blot.Results There was no statistical significant difference in the gene expression and protein level of SHBG and caspase-3 in group Ⅰ,Ⅱ and Ⅲ (P >0.05).In Ⅳ,Ⅴ and Ⅵ group,there was no statistical significant difference in the expression level of SHBG and caspase 3 (P >0.05).Compared with group Ⅰ,Ⅱ and Ⅲ,the a-mount of SHBG gene expression decreased obviously,the caspase-3 mRNA and protein level increased obviously and the trophoblast cell ap-optosis increased markedly (P <0.05).Conclusion Through siRNA interference technology can reduce SHBG gene expression in human trophoblastic cells,and it can lead to excessive apoptosis of human trophoblasts cells.

Objective To investigate the effects of CO_2 pneumoperitoneum on the expression of focal adhesion kinase (FAK) of gastric cancer MKN-45 cells. Methods CO_2 pneumoperitoneum with different pressures was simulated in vitro, and the gastric cancer MKN-45 cells were divided into test and control groups. In the test group, gastric cancer MKN-45 cells were cultured in CO_2 pneumoperitoneum with different pressures [5, 10 or 15 mm Hg (1 mm Hg =0.133 kPa)] for 4 hours. The condition of the cells exposed to CO_2 pneumoperitoneum with a pressure of 15 mm Hg was observed at 0.5, 2 and 4 hours. Gastric cancer MKN-45 cells in control group were cultured at normal atmospheric pressure. The expression of FAK and phosphorylated FAK (FAK Tyr397) of each group was detected by Western blot. Multiple-group analysis was done by one-way ANOVA, and intergroup comparison was done by LSD test. Results In CO_2 pneumoperitoneum with pressures of 5, 10, 15 mm Hg, the expression of FAK was 2.14±0.17, 2.07±0.21 and 2.52±0.26, respectively, and the expression of FAK Tyr397 was 1.82±0.28, 1.93±0.52 and 3.71±0.37, respectively. The expression of FAK and FAK Tyr397 in the control group was 2.43±0.46 and 1.71±0.23, respectively. We found significant differences between the 2 groups (F = 2.171, 26.951, P < 0.01). After gastric cancer MKN-45 cells being treated for 0.5, 2 and 4 hours in CO_2 pneumoperitoneum with a pressure of 15 mm Hg, the expression of FAK Tyr397 was 3.41±0.44, 4.12±0.56 and 5.24±0.41 respectively, which is also significantly different (F =116.119, P < 0.01). The expression of FAK Tyr397 was back to 0.72±0.16 1 hour after the release of CO_2. Conclusions CO_2 pneumoperitoneum with different pressures can not promote the expression of FAK in gastric cancer MKN-45 cells which had been cultured for 4 hours, but can activate FAK through promoting its phosphorylation. The degree of FAK phosphorylation increases with pressure and time, and the activity of FAK decreases to pretreatment level rapidly once pressure is released.

Objective To asses the value of ST segment elevation of aVR lead (aVRSTE) in patients with acute ST segment elevation myocardial infarction (STEMI). Method Myocardial enzymes detection, electrocar-dingraphy, emergency eornary artery angiography, echoeardiography [taken(10±2) days after emergency cornary artery angiography] were obtained and analyzed in 140 consecutive patients with STEMI enrolled in this study. The value of aVRSTE (≥0.05 mV) was assessed for detecting left main stem lesions(defined as ≥50% stenosis of or acute embolism of left main stem)or its equivalent (defined as total or subtotal acute occlusion of left anterior de-scending artery), and predicting the left ventricular systolic function after myocardial infarction. Results The sensitivity, specificity, positive predictive value and negative predictive value of aVRSIE in detection of left main stem lesions were 72.73 % (8/11), 83.72 % (108/129),27.59 % (8/29) and 97.30% (108/111), respectively; in detection of left main stem lesions or its equivalent, they were 41.86 % (18/43), 88.66% (86/97), 62.07 % (18/29), 77.48% (86/111); aVRSYE were combined with STaVR-STv1>0 to detect left main stem lesions, the semi-tivity, specificity, positive predictive value and negative predictive value were 63.64% (7/11),98.45%(127/129),77.78%(7/9),96.95% (127/131). Patients were divided into two groups: groups A with aVRSIE and group B without aVRSYE. KIIJJP class,and left ventricular ejection fraction (LVEF) in group A was higher than those in group B (P<0.05). Conclusions For patients with STEMI: (1) aVRSTE indicated left main stem le-sions or its equivalent; if combined with STaVR-STv1>0, it indicated left main stem lesions more strongly; (2)aVRSTE predicted poorer left ventricular systohc function short time after STEMI.
