Objective To explore the relationship between body composition and arterial function index,especially augmentation index(AI),and make clear the impacts of gender and age on the relationship.Methotis A total of 3859 health adults were enrolled in this study.Boay composition was measured by bioelectrical impedance,and AI and pulse wave velocity(PWV) were viewed as indictors for arterial function.Correlation analysis and liner regression analysis were used for data comparison.Results Both body mass index(BMI) and body fat rate positively changed with PWV(r=0.114,both P<0.01).However,BMI showed no relation to AI(r=0.022,P>0.05).Body fat rate was positively and independently associated with AI(r=0.263, P<0.01),which was gender-dependent(female:r=0.219,P<0.01;male:r=0.033,P>0.05).When age was concerned,above relationship was more stronger in participants ≤50 years(β=0.479 vs β=0.321,P<0.01).Conclusion Body fat mass may be a predicting factor of changes in AI.Gender and age could affect the relationship between body fat and rtery function.

Objective To evaluated the treatment results of late-course accelerated hyperfractionated radiotherapy combined with chemotherapy for advanced esophageal carcinoma. Methods 72 patients with advanced esophageal cancer were randomized into two groups. The late-course accelerated hyperfractionated radiotherapy combined with chemotherapy(LCAF+CT)group received the induction chemotherapy for two cycles, followed by conventional fractionation radiotherapy to a dose of 36 Gy, then changed into accelerated hyperfractionated radiotherapy to a total dose of 60 ~ 66 Gy. The conventional fractionation radiotherapy combined with chemotherapy(CF+CT)group received the chemotherapy that it was similar to LCAF+CT group, and used the conventional fractionation radiotherapy to a total dose of 60 ~ 66 Gy. Results The 1-, 3- and 5-year survival rates were 82.3 %, 51.6 %, 38.2 % in the LCAF+CT group, and 73.8 %, 31.5 %, 18.6 % in the CF+CT group. The differences of 3- and 5-year survival rates were statistically significant (P 0.05). Conclusion Late-coures accelerated hyperfractionated radiotherapy combined with chemotherapy might improve the treatment efficacy of advanced esophageal cancer and lengthen the suvival time. The toxic and side effects of LCAF+CT group were more severe than those of CF+CT group, but they were well tolerable.

Objective:To investigate the effects of 5-aza-2′deoxycytidine(5-aza-dC),a DNA methyltransferase (DNMT)inhibitor, on the methylation status of the RECK gene and the invasion of salivary adenoid cystic carcinoma cell lines.Methods:Methylation-specific PCR,Western blot analysis and quantitative real-time PCR were used to investigate the methylation status of RECK gene and the expression of RECK mRNA and protein in SACC cell lines.The invasive ability of SACC cells was examined by transwell assay. Results:Promoter methylation was only found in ACC-Mcell line and not in ACC-2 cell line.Treatment of ACC-Mcells with 5-aza-dC partially reversed the hypermethylation status of the RECK gene and significantly enhanced the expression level of mRNA and pro-tein of RECK,suppressed ACC-Mcell invasive ability.Conclusion:5-aza-dC can inhibit ACC-Mcell invasion by reversal of hyperm-ethylation status of RECK gene.

Objective:In order to provide policy-makers with basis and reference for improving the operational efficiency of county general public hospitals, this paper studies the changes in overall efficiency, technical efficiency and scale efficiency of 40 county general public hospitals in Fujian province from 2009 to 2014 , as well as how the to-tal factor productivity changes over the time. Methods: After collecting the relevant data of hospital operations from 2009 to 2014, this paper uses CCR, BBC, Malmquist model and other data envelopment analysis (DEA) methods to analyze the data. Results:The vast majority of those 40 county general public hospitals are in decreasing state. The total factor productivity of 40 hospitals from 2009 to 2014 is 1. 019. There are 21 hospitals (52. 5%) that slightly im-proved their productivity, of which 3 hospitals increased their productivity mainly due to technological progress, 3 hospitals due to efficiency increase, and the rest 15 hospitals due to the effect of both technological progress and effi-ciency increase. Conclusions:The operational efficiency of county general public hospitals in Fujian province is gen-erally insufficient, and there are significant differences between operating efficiency of different regions. The efficien-cy of hospitals in mountainous areas had increased, but the efficiency of hospitals in coastal areas had decreased. Therefore, in order to increase investment in county general public hospitals, the government should take differential policy and pay attention to the reasonable control of hospital size, as well as to strengthen the connotation building and attach importance to improving medical service technologies.

We investigated and analyzed the first case of human infection with avian influenza A(H9N2) virus in Yunnan Province,China,so as to provide a better basis for preventing and controlling human infections with viruses of animal origin in the future.We carried out the field epidemiological survey among the patient,close contacts and the live poultry markets,detected and analyzed the samples from patient and the outdoor environment.Results showed that the 9-month-old boy was a case of human infection with avian influenza A(H9N2) virus with the history of live poultry markets exposure and the results of nucleic acid detection and virus isolation.There was a lot of contamination of the avian influenza virus in the live poultry markets.The second generation cases have not occurred.The monitoring of pneumonia of unknown etiology and influenza like cases in medical institutions is the important means to find timely cases of human infected with avian influenza.Regular disinfection and closing-down of live poultry markets are key measures to reduce the exposure opportunity.
