Objective To investigate the prevalence of and risk factors for glucocorticoid-induced diabetes mellitus (GDM) in patients with pemphigus or pemphigoid receiving glucocorticoid therapy.Methods This study included 68 hospitalized patients with pemphigus or pemphigoid receiving glucocorticoid therapy in the Institute of Dermatology,Chinese Academy of Medical Sciences and Peking Union Medical College from December 2011 to January 2013.Comparisons were carried out between patients with GDM and those without regarding multiple parameters,including age,sex,body mass index (BMI),pathological type,initial dose and maximum daily dose of glucocorticoids,family history of diabetes mellitus,immunosuppressive treatment,etc.Independent samples t test was used for intergroup comparisons,Chi-square test and Fisher exact probability test for the analysis of count data,and a logistic regression model for the determination of risk factors.Results Among the 68 patients,26 (38.2％) developed GDM during glucocorticoid therapy.Univariate logistic regression analysis showed that the initial dose of glucocorticoids (P ＜ 0.05,OR 1.023,95％ CI 1.002-1.044),maximum daily dose of glucocorticoids(P ＜ 0.01,OR 1.037,95％ CI 1.013-1.062),duration of glucocorticoid treatment (P ＜ 0.05,OR 1.143,95％ CI 1.028-1.271),BMI (P ＜ 0.01,OR 1.265,95％ CI 1.080-1.481) and dexamethasone use (P ＜ 0.01,OR 6.0,95％ CI 1.887-19.076) were risk factors for GDM in these patients.Multivariate logistic regression analysis showed that BMI (P ＜ 0.05,OR 1.223,95％ CI 1.017-1.471) and maximum daily dose of glucocorticoids (P ＜ 0.05,OR 1.037,95％ CI 1.009-1.065) were independent risk factors for GDM.Conclusions In this study,38.2％ of the patients with pemphigus or pemphigoid developed GDM during glucocorticoid therapy.BMI and maximum daily dose of glucocorticoids seem to be independent risk factors for GDM.

· ATM:To analyze bacterial spectrum and drug sensitivity in conjunctival sac of cataract patients of Kazak.
· METHODS:A total of 538 cases of conjunctival sac secretion in cataract patients of Kazak were collected.The samples were cultured and their sensibilities to antibiotics were tested.
· RESULTS: The bacterial culture was positive in 214 cases.The positive rate was 39.8%. The variety of pathogenic bacteria were mainly made up of gram positive cocci ( 88.3%), and most of them were Staphylococcus epidermidis ( 66.4%), followed by Micrococcus(9.8%).Sex had no effect on conjunctival bacteria rate in the cataract patients of Kazak, while age, place of residence had an effect on camier rate. The camier rate of conjunctival bacteria was significantly higher in people over 60 years old than that in people with age between 40 to 59 years old.And the people from city had a significant lower bacteria positive rate than those from countryside and pastoral. Most of grams were sensitive to Vancomycin, Teicoplanin, Rifampicin, Duly cloth mildew mutual and Amikacin, the tolerance was less than 20%, and they usually had higher tolerance to Penicillin, Erythromycin, Tetracycline and Chloramphenicol (>70%) .
·CONCLUSlON:Gram positivecocci is the most common bacteria in conjunctival sac in cataract patients of Kazak. Staphylococcus epidermidis was most common, followed by Micrococcus.The germ-carrying rate of conjunctival SAC in Kazakh population is associated with the patient’s age and area of residence.The clinical use of antibacterial drugs should be strictly grasp the indications, to reduce the incidence of bacterial resistance.

Background Macular hole retinal detachment(MHRD) causes severe decrease of vision.Pars plana vitrectomy has been applied for MHRD.Silicone oil and C3F8 have been used as intraocular tamponade materials,while there are still controversity on their efficacy.Objective This trial was to evaluate the efficacy of vitreous surgery combined with silicone oil or C3F8 tamponade for patients with MHRD in highly myopic eyes.Methods A retrospective case-controlled study was designed.Fifty-one patients who underwent vitrectomy with intraocular tamponade were retrospectively analyzed.The best corrected visual acuity(BCVA) before and after surgery were examined and campared between two groups.The rate of recurrent RD and macular hole closed were analyzed.Results There was no significant difference in BCVA between silicone oil group and C3F8 tamponade group before and after surgery(U=266.000,P =0.286 ; U =205.000,P =0.029).The BCVA after surgery was elevated in both groups (Z=-2.729,P =0.006 ; Z =-3.273,P =0.001).The rates of recurrent RD and macular hole closed were no difference between two groups(P=0.894,1.000).There were no other complications but cataract.Conclusions C3F8 tamponade of MHRD in high myopic eyes show the same efficacy as silicone oil tamponade.

Objective To develop an effective and broad immune protective H5N1 vaccine.Methods We first developed two recombinant vaccinia ( Tiantan strain) virus ( rTTV ) based H5N1 vaccines, which consisted of bicistron expressing the hemagglutinin(HA) and matrix protein 2(M2), or bicistron expressing the neuraminidase(NA) and matrix protein 1 (M1). The expression of H5N1 protein in rTTVs was confirmed. We immunized the BALB/c mice twice with two kind of dose ( 104 PFU, 107 PFU)using different combination. Subsequently, we assessed the humoral and cellular immune response in vaccinated mice. Results Our data showed that rTTV-based H5N1 vaccine induced rapidly robust HA- and NAspecific antibody level and IFN-γ secreting form cell(SFC) with either single dose of 107 PFU or twice dose of 104 PFU or 107 PFU. We also detected significant neutralizing antibody and matrix-specific immune response. In addition, we found that immunization with two kind of rTTV-based H5N1 vaccines induced much high level of M2-specific antibody than that with single of rTTV-based H5N1 vaccine. Conclusion rTTVbased H5N1 vaccines in this study elicited board array of immunity and our study offers a promising alternative H5N1 vaccine candidates with favorable potential to prevent various H5N1 pandemic.

Twenty Newcastle disease virus(NDV)strains were isolated from diseased chicken and geese in field outbreaks during 2005 and 2006 in some regions of Jiangsu and Guangxi,and the antigenic analysis of the all NDV isolates had been done based on the reaction spectrum with a panel of monoclonal antibodies to the HN glycoprotein.The entire ORFs encoding HN protein of these NDV isolates were amplified by RT-PCR successfully,cloned and sequenced.The resultant sequences of HN genes of 13 isolates of chicken origin and 7 isolates of goose origin were gained and analyzed.The results of reaction spectrum showed that there were some distinct differences in the antigenic epitopes among the 20 NDV isolates.And the sequences revealed that the coding regions of the HN genes of these isolates all consisted of 1716 nt characteristic of virulent strains of NDV,coding for 571 amino acids.Neucleotides sequence homology were found to be from 94.8%to 100%among 18 NDV isolates of genotypeⅦ,and the neucleotides sequence homology between all the isolates and the other genotypeⅦstrains of recent years in China ranged from 92.1%to 99.6%.The deduced amino acid sequences and the receptor-binding regions of HN proteins between the NDV isolates of chicken origin and of goose origin were compared and analyzed.The results showed that some unique amino acid substitutions were found in the genome of the NDV isolates,and the close genetic similarity provided evidence for epidemiological linkage between the NDV isolates of chicken origin and of goose origin in the same period.

Objective To predict the trend of hepatocellular carcinoma (HCC) mortality and investigate the features of its mortality including age, period, and birth cohort in males living in Haimen city of Jiangsu province, China. Methods Grey model (GM) was modeled using standardized mortality rate (SMR) of HCC from 1993 to 2006, and was applied to predicting SMR until 2012. Based on the mortality density (MD) for a four-year period, the goodness-of-fit of models and comparisons between models were evaluated so as to obtain the best one among these models including the effects of intercept, age-period-cohort (APC) , age-period (AP), age-cohort (AC),period-cohort(PC), and APC. Both APC full model and the best model were used to estimate effects of age, period, and cohort on HCC mortality. In addition, MD from 2005 to 2012 was predicted by the best model. Results Predictions based on GM (1,1 )showed that SMR was 48.578 per 100 000 population (relative error=-1.267% ) in 2007 year, which declined between 2008 and 2012. The lowest value was 45.578 per 100 000 people (in the 2012 year). The results of fitted models and comparisons between models showed that AP model was the best one (△G2=9.065,AIC=202.544). The curvatures of the effects of the three factors from APC model suggested that significances existed in changes of curvatures of 36.5-40.5 years old- (-0.368) and 64.5-68.5 years old-(-0.489) as well as in the change of 1956-1959 birth cohort (C21949.5. 1967.5=-0.492). The estimation of relative risks for AP model showed that the age effects were upward to 64.5-68.5 years old-, then downward; and that the period effects were found to be declined between 1993 and 2004. Predictions based on AP model suggested the decrease of HCC mortality. Conclusion The slightly decreasing trend of HCC mortality for males might be explained by age, period and a minor birth cohort effects in Haimen of China.

Objective To investigate the distribution of death among human immunodeficiency virus/acquired immuno deficiency syndrome(HIV/AIDS) cases in Guizhou Province from 1995 to 2017. Methods The HIV/AIDS death cases from 1995 to 2017 were downloaded from “Chinese National Comprehensive HIV/AIDS Prevention and care Information system” in Guizhou Province and were analyzed. Results From 1995 to 2017, Guizhou Province reported a total of 43 794 HIV/AIDS cases and 11 527 deaths according to current address. After excluding missing persons, the HIV/AIDS mortality rate of the province was 29.8%. The proportion of reported HIV/AIDS cases died in the same year ( 21995-2012=139.5, P<0.001; 22012-2015=28.2, P<0.001) and the proportion of HIV/AIDS cases ( 21995-2012=109.1, P<0.001; 22012-2014=57.2, P<0.001) who survived at the beginning but died later in the year all showed a trend being low-high-low. In the analysis of the detection history of death cases, the detection proportion of cluster of differentiation 4(CD4) T-cell and the proportion of antiviral treatment had been increasing year by year. The analysis of the cause of death found that the proportion of death caused by AIDS increased firstly and then declined, and the proportion of death due to excessive drug abuse showed a trend of declining year by year. Conclusions The mortality rate of HIV/AIDS in Guizhou Province was still high, and decreased rather slow. Expanding the coverage of HIV monitoring and screening is one of the key tasks of AIDS prevention and control. CD4+T-cell testing and free antiviral treatment should be strengthened to reduce the mortality rate of HIV/AIDS in Guizhou Province in the future.
