Great difficulties were existed in clinical teaching in hospitals for infectious diseases. Therefore,a centralized hospital teaching rounds,a new clinical teaching practice was taken in a hospital for infectious diseases. During seven years' practice,a basic mode of centralized hospital teaching rounds was established,which contains many aspects such as organizational form,time arrangement,case se-lection and operation procedures. Its effectiveness was evaluated accoding to the following aspects:number of people attending hospital teaching rounds,composition of these people,satisfaction of these people, comparison of ward rounds data recorded nowadays and 7 years before and assembling all the rounds records into a book. Results indicated that this measure overcame the limitations of the specialized hospi-tals to some extent and played an important role in improving clinical teaching quality.

Objective To construct the lentiviral vector of RNA interference(RNAi) for DEK,and to detect its effect on breast cancer cell growth.Methods The DEK siRNA was designed and constructed based on DEK sequence using a lentiviral vector.The lentivirul vector containing DEK siRNA was named PSIH-H1-DEK as confirmed by PCR and sequenceing.PSIH-H1-DEK was then packaged with accessory plasmids into lentivirus in 293T cells and selected for 2 weeks with puromycin ( puro ) before the mixed colonies stably expressing DEK siRNA were obtained and the DEK expression was detected by real time PCR( RT-PCR) and Western blotting.The effect of DEK siRNA on ZR75-1 cell growth was determined by cell counting kit.Results Western blot and RT-PCR showed that PSIH-H1-DEK siRNA could suppress DEK gene expression.Suppression of DEK could markedly inhibit the growth of ZR75-1 cells.Conclusion The lentivirus-mediated DEK siRNA is obtained,which will facilitate further research on DEK function in breast cancer development.

Objective Assisted reproductive technology ( ART) is associated with an increased incidence of offspring de-fects.The aim of this study was to investigate the impact of embryo vitrification in in vitro fertilization ( IVF) on the growth and devel-opment of the offspring by comparing the development status of mouse offspring from fresh embryo versus vitrified embryo transplanta-tion. Methods This study included three groups of mouse offspring , from natural fertilization ( n=12 ) , fresh embryo transplanta-tion (FET, n=9), and vitrified embryo transplantation (VET, n=9).We compared the body weight and body fat content in the sex-ually mature stage among the three groups of mice . Results No obvious differences were found in the morphology of the embryos be-tween the FET and VET groups .The body weight of the mouse offspring was significantly higher in the VET than in the natural control group at 0 postnatal (PN) week (P<0.01) and 12 PN weeks (P<0.01), and so was it in the FET group than in the control at 0 PN week (P<0.01) and 6 PN weeks (P<0.05).The body fat content at sexual maturity was remarkably higher in the VET than in the FET and control groups ([9.32 ±4.34] vs [5.24 ±2.56] and [2.80 ± 0.48] g, P<0.05), and so was the muscle content in the VET than in the control ([33.77 ±4.22] vs [27.50 ±1.79] g, P<0.01). Conclusion In IVF, fresh embryo transplantation has less interference with the growth and development of mouse offspring than vitri-fied embryo transplantation .

AIM: To investigate the role of NF-?B/I?B signal pathway in the regulation of (cyclooxygenase-2) (COX-2) expression in human mesangial cells (HMC). METHODS: The PGE_2 concentration in supernatants of HMC was measured by radioimmunoassay. COX-2 mRNA and protein expression were determined by RT-PCR and Western blot. Electrophoretic mobility shift assay (EMSA) and Western blot were used to detect the activity of NF-?B and degradation of I?B. RESULTS: IL-1? significantly upregulated COX-2 expression and PGE_2 production in HMC. Significant up-regulation of NF-?B activation, nuclear translocation of p65 subunit, and degradation of I?B ? and I?B ? were observed in IL-1?-induced HMC. CONCLUSION: Expression of COX-2 in IL-1?-induced HMC is mediated by NF-?B/I?B signal pathway. [

Objective To elucidate whether Ang Ⅱ indnces the proliferation of mesangial cells through ROS-EGFR-JNK-AP-1 signaling pathway. Methods The incorporation of 3H-thymidine (3H-TdR) and cell count were used to measure mesangial cell (MC) proliferation. ROS production was determined by DCFDA fluorescence. EGFR and JNK activation was assayed by Western blot. Results Ang Ⅱ significantly enhanced ROS production in mesangial cells, which was up-regulated by 2.26 folds of control group after incubation with Ang Ⅱ for 60 min. Ang Ⅱ induced EGFR phosphorylation in dose- and time-dependent manner, with the peak (3.96 folds increase) at 30 min. EGFR phosphorylation was significantly blocked by AT1R antagonist losartan, antioxidant NAC, and NADPH oxidase inhibitor apocynin and DPI. EGFR antagonist AG1478 significantly inhibited Ang Ⅱ-induced mcsangial cell proliferation. Losartan, NAC, apocynin, DPI, and AG1478 ahnost abolished Ang Ⅱ-induced JNK activation. Conclusions ROS-EGFR-JNK-AP-1 signaling pathway is involved in Ang Ⅱ-induced mesangial cell proliferation. Apocynin and AG 1478 may be used as new therapy.

Objective To understand the relationship between the dietary patterns and metabolic syndrome among elderly people in Zhejiang province,in order to provide scientific basis and reference for nutrition interventions.Methods Data were obtained from the 2010-2012 Chinese National Nutrition and Health Survey,and factor analysis was used to obtain food patterns among elderly people in Zhejiang province.The Logistic regression was used to explore the association of the food patterns with metabolic syndrome and its components.Results The intakes of bean products,nuts,fruits,eggs,and milk in elderly people were generally low,and the intakes of livestock and poultry meat,cooking oil and salt were relatively high.5 dietary patterns were derived by factor analysis:high-quality protein diet,mediterranean diet,condiments diet,traditional dietary pattern and western dietary pattern.The medical test results in 780 elderly people showed that the standardized prevalence of metabolic syndrome in the elderly was 28.8％,standardized central obesity rate was 41.2％,standardized hypertension rate was 50.3％ and standardized hyperglycemia rate was 39.5％.Logistic regression analysis showed that different dietary patterns had different effects on the metabolic syndrome and its components.Conclusions The prevalence rate of metabolic syndrome and the abnormal rates of its components are high in the elderly in Zhejiang.The intakes of fruits and milk are generally low,and intakes of livestock and poultry meat,cooking oil and salt are relatively high.The relationship between dietary patterns and MS or its components is complicated,so it is necessary to guide the elderly people to adopt reasonable diet by referring to the Diet Pagoda in order to reduce the risk of MS or its components.

OBJECTIVETo compare the applicative effect of four diagnostic criteria of metabolic syndrome (MS) among the urban adult population of Zhejiang Province.

METHODSAccording to multi-stage stratified and proportional to size, cluster, random sampling principle, 3 417 adults population at urban areas were extracted by random number method from 320 families of Shangcheng and Jianggan community in Hangzhou,Jiangdong community in Ningbo and Wucheng community in Jinhua in 2009 and 2010 respectively, which excluded pregnant, wet nurse, children, and those who were at least 18 years of age. Height, weight, waist, blood pressure, fasting plasma glucose (FBG) , 2-hour postprandial blood glucose (2h-PBG), TG and HDL-C of all the subjects were measured by standard method. MS was diagnosed and compared according to four diagnostic criteria:Chinese Medical Association Diabetic Society (CDS), Joint Committee for Developing Chinese Guidelines (JCDCG), American National Cholesterol Education Program Adult Treatment PaneI II in 2005 (ATPIII) and International Diabetes Federation (IDF), respectively.

RESULTSThe high prevalence of MS diagnosed by the criteria of ATPIII was 21.6% (737/3 417) , while the lowest prevalence diagnosed by CDS was 9.8% (335/3 417), the result of consistency check demonstrated the MS diagnostic criteria of ATPIII and IDF, ATPIII and JCDCG were in strong and the same accordance with the concordance rate, Kappa value was 0.75, while the consistency of the criteria of ATP III and CDS were in relatively weak agreement, Kappa value was 0.53; the detection result of MS abnormal components showed the highest proportion of having ≥ 3 risk factors was presented by ATPIII among subjects diagnosed as MS (100.0%) , meanwhile, the lowest proportion of having ≥ 3 risk factors was also found by ATPIII among those MS-free (0.8%) .

CONCLUSIONSThe criteria of ATPIII may have more sensitivity when screening MS and its abnormal components.However, it's limited to extrapolate the results from the cross-sectional survey to the total population.
