Objective To explore the clinical significance of STING in peripheral blood in patients with primary biliary cirrho-sis.Methods Admitted 28 PBC patients hospitalized in Shanghai Changhai Hospital and Shanghai Changzheng Hospital from January 2014 to October 2015.Also enrolled 28 healthy controls.Baseline data and laboratory indicators were extrac-ted,and STING mRNA expression was determined using q-PCR.The correlation between STING and clinical parameters were analyzed.The changes of STING mRNA in 5 followed-up patients with PBC were analyzed.Results Compared with healthy controls,STING mRNA was significantly increased in PBC patients and was increased in patients with severer dis-ease stages (U=0.00,P<0.05).STING was positively correlated with Mayo risk and GGT (R=0.45,R=0.42,P<0.05),and not AST,ALT or ALP (R=0.33,0.21,0.27,P>0.05).After therapy,STING mRNA were significantly re-duced in 5 PBC patients (U=0.00,P<0.05).Conclusion STING may be involved in PBC pathogenesis.

Objective To investigate the efficiency and mechanism of differentiation of reprogrammed adipose-derived stem cells (ADSCs) to neurons in vitro.Methods ADSCs from rats were cultured in vitro and then purified and identified.ADSCs at the third passage were divided into three groups:ADSCs without lentivirus-mediated gene transfection (blank group),ADSCs transfected with lentivirus carrying no neurogenin2 (Ngn2) (empty virus group) and ADSCs with lentivirus-mediated transfection of Ngn2 (Ngn2 group).All groups were induced in the medium containing cell growth factor for 15 days.The positive expression of neuron-specific nuclear protein (NeuN) in three groups was detected using immunofluorescence method so as to observe the efficiency of neuron differentiation.Expression variances of Mash1,Hes1 and Dll1 in each group were detected by Western blot analysis and the mechanism of differentiation was also discussed.Results After 15 days of induction,positive expression rate of NeuN in Ngn2 group,empty virus group,blank group was 90.12%,45.34% and 40.26% respectively,with significant differences among groups (P < 0.01).Western blot analysis showed that Ngn2 group had a significantly higher expression of Dll1 (P <0.01) and obvious lower expressions of Hes1 and Mash1 (P <0.01),as compared with empty virus group and blank group.However,there were no significant differences of expression levels of Dll1,Mash1 and Hes1 between empty virus group and blank group (P > 0.05).Conclusions After induction,the ratio of neuron differentiation of reprogrammed ADSCs is increased by almost 99%,as compared with simple ADSCs.The increased dfferentiation of reprogrammedADSCs to neurons may be associated with the inhibition of notch signaling through up-regulating Dll1 and down-regulating Mash1 and Hesl.

Objective To study the variation in numbers of patients attended in the Emergency Department (ER) of a large - scale teaching hospital during weekends or holidays and workdays in order to find out an objective criterion for the assessment of ER overcrowding and the regularity of ER overcrowding.Methods It was a prospective observational study of variation in number of.patient attended in ER during different periods of time round the clock observed from May 1 through October 31 in 2008 -2010 with 110000 emergency patients annually.The roles of diurnal rhythm,holiday phenomenon and medical coverage in the variation in numbers of patients were observed.The multiple logistic regression analysis was used to define the criterion of ED overcrowding.Results During workdays,the regularity of variation in number of critically ill patients seen to in ER was distinctive,the number of patients peaked in the period of 20:00 -22:00 and bottomed out in the period of 4:00 -6:00,while overcrowding scores of both peak and bottom were carried out 2 hours later.The number of emergency patients significantly increased at weekends and long holidays in a form of double peaks,from 10 am to 12 pm and 8 pm to 10 pm.The number of emergency patients was obviously determined by the provisions of medical coverage,but it was only true to non - critical patients,while the number of critical patients did not noticeably change during weekends or holydays.Multivariate regression analysis showed that the number of emergency patient attended in ER ( B =0.027,P <0.01 ) and the rate of emergency bed occupancy ( B =5.25,P <0.01 ) in the period of two hours significantly correlated with the ER overcrowding in the coming period of two hours (B =0.027,P <0.01,B =5.25,P < 0.01,respectively).Conclusions The demand for critical care resources varies up and down all the time.The variation in volume of critical patients is quite regular during workdays and weekdays or holydays.It is important to separate critical patients from non - critical patients in order to divert non - critical patients quickly.Prediction of overcrowding in ER can be made with knowledge of the number of patient attended and the rate of bed occupancy,if the provisions of medical coverage unchanged.This regularity of variation in number of patients can be used as a practical guidance to rational allocation of critical care resources and improvement of patient throughput.
