0.05), iAs% was much higher and the levels of FMR, SMR and DMA% were significantly lower in skin lesion group compared with the control (P

Objective To assess the blood safety under the current sero-screening program and gain experience on how to implement NAT as a routine assay for blood screening in China. Methods Sera from 103,539 non-remunerated donors of Shanghai blood center were tested by Chiron's Procleix(TMA HIV-1/HCV Assay in 2 study stages with 8 and 24 sample-pool respectively. Results 5 NAT positive samples were found to be Anti-HCV EIA-2 test positive at the same time. No window period cases of HIV-1/HCV were found in this donor group. But 275 (0.27% ) anti-HCV and 107 (0. 10%) anti-HIV false positive samples were identified by the second sero-screening. Conclusion The blood quality of Shanghai city was high to be close to the level of developed countries and the window period risk of HIV-1 and HCV was less than 1:100,000. With its high sensitivity and specificity,Procleix( TMA HIV-1/HCV Assay can be used in routine blood screening in China.

Objective:To explore the discrimination against the patients with mental disorders and current situation of awareness of mental health knowledge of medical postgraduates and their relationship.Methods:A questionnaire survey was conducted among 132 medical postgraduates in October 2016 using the assessment scale of discrimination against patients with mental disorders and mental health knowledge awareness questionnaire,which derived from mental health work indicators survey and evaluation program issued by the General Office of the Ministry of Health in 2010.Results:There was significant gender difference (P ＜0.01)in the overall score and the score of each dimension of assessment scale of discrimination against patients with mental disorders,and the score of mental health knowledge was (13.93-± 3.13).There was significant negative correlation between scores of assessment scale of discrimination against patients with mental disorders and mental health knowledge.Multiple linear regression analysis showed that awareness of mental health knowledge could predict the discrimination against the patients with mental disorders and all its factors.Conclusion:Awareness of mental health knowledge in medical post graduates can predict the discrimination against the patients with mental disorders.Medical universities should carry out corresponding education and publicity work with pertinence.

Clinical data of 448 patients aged ≥60 years with osteoporotic hip fractures admitted in Shanghai Huashan Hospital between January 2010 and December 2014 were retrospectively analyzed.Among 448 cases,there were 143 males and 305 females;196 cases aged 80-89 years (43.8％) and 137 cases aged 70-79 years (30.6％);304 cases of femoral neck fracture (67.9％) and 144 cases of intertrochanteric femoral fracture (32.1％);the fractures caused by fall in 328 cases (73.2％) and comorbidity with hypertension and diabetes mellitus in 415 cases (92.6％).Two hundred and sixty eight patients were followed up for 2 years,among whom re-fractures occurred in 17 cases.The study indicates that health education is important for prevention of osteoporotic fractures in elderly people.

Objective The patients with non-small cell lung cancer ( NSCLC) are still at risk of brain metastasis after surgi-cal treatment.The study was to investigate the clinical characteristics and the risk factors for postoperative brain metastasis in patients with NSCLC in order to provide references for prophylactic cranial irradiation ( PCI) . Methods The clinical and prognostic data of 213 patients with NSCLC in our department of oncology from February 2008 to February 2012 were retrospectively analyzed.The occur-rences of postoperative brain metastasis in NSCLC patients with different characteristics were observed.Cox model was used to investi-gate the risk factors for postoperative brain metastasis in patients with NSCLC. Results The overall cumulative rate of brain metasta-sis was 23.9%(51/213) and the rates of brain metastasis at 1-year, 2-year, 3-year after surgery were 6.1%, 14.1%, 22.5% re-spectively.Univariate analysis showed that the rates of postoperative brain metastasis in NSCLC patients with different ages, histological types, tumor stages and CEA levels were statistically significant (P<0.05).Cox regression showed that adenocarcinoma (HR=2.00, 95%CI:1.11~3.64), lung cancer stageⅢ(HR=3.70, 95%CI:1.67~8.25) and high CEA (≥5.0μg/L)(HR=3.16, 95%CI:1.60~6.25) were risk factors for postoperative brain metastasis in patients with NSCLC.The survival time in NSCLC patients with brain metastasis was remarkably lower than that in patients without brain metastasis (P<0.05). Conclusion The NSCLC pa-tients with adenocarcinoma, III stage disease, or high CEA are more likely to develop brain metastasis after surgery, which should be the focus of PCI.

Objective To investigate the prevalence and clinical characteristics of Sj?gren′s syndrome-interstitial lung disease (SS-ILD). Methods 136 patients with SS were studied. Anti-SSA and Anti-SSB antibodies were measured by Western blot. The inpatients had chest X ray, chest HRCT and pulmonary function examined. Results ①pSS-ILD patients with postive anti-SSA antibody were proned to have interstitial lung disease and the ILD were more severe. ②HRCT showed that sSS-ILD were more severe than that of pSS-ILD. ③Lung capacity of pSS-ILD decreased more frequently than sSS-ILD. sSS-ILD mainly had venti-latory function abnormalities. The lung function impairment of both were dominated by small airways dysfunction and decrease of TLCO. Conclusion SS patients should be examined by HRCT and lung function tests should be performed in the course of the disease to find out and treat ILD.

The biotechnology of glycolipid fermented b y a bacillus coagulans was studied and the fermentation pro cess in 10L bioreactor was conducted.Suitable medium contained 6% bean oil as ca rbon source,3 5g/L NaNO 3 as nitrogen source,0 75g/L yeast extract and some i no rganic salts.The fermentation temperature of 30℃,initial pH of 8 5,strring rev olution of 150～240r/min and fermentation period of 96h proved to be optimal.The yield of glycolipid in 10L bioreactor was 7 073g/L.
