This article elucidates the relationship between the human susceptibility to obesity and gene polymorphisms such as peroxisome proliferators-activated receptors(PPARs)and PPAR?coactivator-1,along with milestones in the formation and development of capacity for fat deposition during evolutionary history of human.An biological evolutionary analysis,identifying factors favoring the energy stores,may be helpful to the development of preventive public health strategies.

Objective To evaluate the effects of endogenous NO on the chemosensitivity of human breast cancer cell. Methods MCF-7 cells were cultured as monolayer, incubated with cytokine IL-1β. The pro-duction of NO was detected by NO assay. The expression of iNOS protein was measured by Western blotting. Establishing control group and experimental group, the chemosensitivity of MCF-7 cells incubated by L-NMMA and L-Arg to ADM and 5-Fu was studied by MTT assay. Results There was a positive correlation of dose-dependence between NO production and IL-1β concentration. MCF-7 cells expressed plenty of iNOS by induetion of IL-1β. There was no significant difference on iNOS whether L-NMMA and L-Arg existed or not. Incubating MCF-7 cells with 0. 5 μmol/L or 1 μmol/L ADM, the survival rate of experiment group was remarkablely decreased(P < 0.05) ; L-NMMA significantly increased survival rate of experiment group(P < O. 05) ; L-Arg decreased survival rate of experiment group(P < 0.05). Conclusion The induction of IL-113 in MCF-7 cells can increase the production of endogenous NO, which increases MCF-7 cells' sensitivity to chemotherapy.

Obiective To introduce the design and implementation of system for health examination and health monitoring according to the needs and workflow of the Health Examination Center. Methods The system has an effective configuration based on HL7 and smart client technology. Results The system can truly meet the actual needs and realize the digitizing management of the health examination center. Conclusion The system plays an important role in optimizing the wotkflow and can improve service quality and efficiency of health examination to promote digital construction in hospital.

Background Clinical researches showed that antimicrobial-resistance of bacterium is gradually serious.It is very important to master pathogen distribution and antimicrobial susceptibility after eye surgery.Objective This study was to investigate the distribution and drug sensitivity of pathogenic bacteria from ocular operative infection in 3-year duration to provide a reference for reasonable selection of antibiotics.Methods Sixtyfive positive specimens were obtained from 65 patients due to postoperative infection in Department of Ophthalmology of Shenzhou Hospital and Shengjing Hospital from 2009 January through 2011 December.The pathogenic bacteria were isolated and then the drug sensitivity test of conventional antibiotics was performed.Results Among the 65 ophthalmic specimens,35 strains of Gram-positive bacteria were isolated with the constituent ratio 53.8％,and 15 strains of Gram-negative bacteria accounted for 23.1％.Fungus was found in 15 cases with the constituent ratio 23.1％.Staphylococcus epidermidis accounted for 42.9％ in Gram-positive bacteria,and Pseudomonas aeruginosa accounted for 33.3％ in Gram-negative bacteria.Aspergillus was the main component of fungus,which accounted for 60.0％ of the proportion 3 strains of methicillin-resistant Staphylococcus aureus (MRSA) in 8 strains of Staphylococcus aureus,but no vancomycin-resistant Enterococcus (VRE) and vancomycin-resistant Staphylococcus (VRS) were seen.The in vitro drug sensitivity test showed that the main Gram-positive bacteria,Staphylococcus epidermidis and Staphylococcus aureus,were sensitive to linezolid,vancomycin,levofloxacin and ciprofloxacin with the sensitive rates ＞50.0％,and these bacteria were lowly sensitive to penicillin and erythromycin with the sensitive rates ≤30.0％.Pseudomonas aeruginosa appeared to be the main Gram-negative bacteria,showing a sensitive rate ≥ 80.0％ to tobramycin,amikacin,ceftazidime,cefepime,cefoperazone/sulbactam,piperacillin/tazobactam,imipenem and meropenem.Conclusions Staphylococcus epidermidis,Staphylococcus aureus,Pseudomonas aeruginosa and Aspergillus are primary pathogens in ocular infection after operation.Antibiotics such as penicillin,erythromycin,levofloxacin,cefotaxime seem to be relatively high resistant to eye infection.To choose sensitive antibiotics timely and reasonably is a key to the prevention and control of ocular infection after operation.

0.05). The interobserver variability in DSCT measurements was lower than in RT-3DE measurements in indexed left atrial volume and function. Conclusion DSCT can provide not only the information of coronary artery,but also highly reliable measurements of left atrial phasic volume and function at the same time.
