Objective:To investigate if injury-related myofibroblast induction could occur in bronchial epithelial cells and the role of TGF-?_1(rhTGF-?_1) in epithelial-myofibroblast transdifferentiation. Methods:Cultured bronchial epithelial cells, 16HBE-14o, were exposed to poly-L-arginine(PLA). Using a immunohistochemical method, ?-smooth muscle actin (?-SMA) expression was detected in those cells after being treated with PLA . Relative activity of chloramphenicol acetyltransferase(CAT) was assessed in 16HBE-14o cells, which were transiently transfected with VSMP8 plasmid containing ?-SMA promoter linked to CAT gene, at different time points after rhTGF-?_1(10 ?g/L) treatment. Results:①?-SMA positive, spindle-shaped cells emerged among the regenerated 16HBE-14o epithelial cells following damage. The number of ?-SMA positive 16HBE-14o cells increased and cell repair was delayed under rhTGF-?_1 stimulation.② CAT activity increased significantly in VSMP8 plasmid transfected 16HBE-14o cells 24 h after TGF-?_1 stimulation.

Objective The mortality rate of the children after surgical repair of congenital heart disease associated with acute renal injure has been reported to be 30％-79％.Peritoneal dialysis is the common treatment method for those patients,but the optimal time to initiate peritoneal dialysis is still controversial.The aim of this study was to investigate the clinic outcome of early peritoneal dialysis to the children following cardiac surgery.Methods We performed a retrospective chart of children following cardiac surgery from January 2008 to December 2009.The total number was 4561,62 of them were performed PD treatment.Data on the PD treatment children were collected from pre-operation to hospital discharge.Early peritoneal dialysis group was defintes as PD initiated at operation room or the interval between the end of operation to starting peritoneal dialysis less than 3hrs.the others were traditional PD group.Results The whole PD treatment rate was 1.36％,15 patients died.The mortality were 10.71％ (3/28) in early PD and 35.29％ (12/34) in conditional PD group respectively (P =0.036).2 patients were met RIFLE(risk,injury,failure,loss,and end-stage renal disease,RIFLE)classification as failure grade in early PD group while 10 patients in traditional PD group (P =0.001).After PD treatment 24hrs,the Vasoactive-Inotrope Scores and serum creatinine values were much lower in the early PD group children than those in the traditional PD group[(19.00 ±2.39) vs(37.00±5.22),P=0.002;(50.51 ±21.84) vs(130.13±76.09),P=0.001)].Conclusion This study shows that early PD can prevent the children after congenital heart surgery to develop AKI,and reduce the severity of the clinic status.Early intervention with PD is associated with low mortality.

Objective This study on a medium-fidelity simulator (SimMan , Laerdal Medical Corpo-ration,Wappingers Falls, NY, USA) examined the management of unanticipated difficult airway by residents of anesthesiology and the effect of training in this context.Methods 30 residents of anesthesiology were devided into two groups (T and E). There were two scenarios investigated:'can't intubate, can oxygenate'(CI) and'can't intubate, can't oxygenate'(CICO). The E group was trained by scene simulation in the second, fourth, sixth month respectively before and after the training, and the T group received the same situation simulation training on the same day after the theoretical training and in the second, sixth month after the training. In con-trast to standard operating procedures, the performance of two groups of trainees was recorded on the basis of pre established evaluation criteria. Data differences between the two groups were analyzed using SPSS 23.0,t test, M-W test andx2 test.ResultIn CI, success rate of placement of astandard and intubating laryngeal mask air-way were high in T group (87％ vs. 55％ ,P=0.037). This was sustained over time. There was no difference in duration and incidence of desaturation between two groups. In CICO, there was a more structured approach following training in T group (P<0.05), which wasn't sustained over time. But this was sustained over 6 months in E group.ConclusionSituational simulation training can significantly improve the anesthesiology residents' ability to take proper response measures to the unexpected difficult airway, and significantly shorten the training time for emergency airway treatment. Repeated situational simulation training should be conducted at intervals of 2 months or less, allowing residents to maintain emergency response to the emergency airway.

Objective To investigate the effect of polyphenol of salvia miltiorrhiza polyphenols combined with collagen sponge in the treatment of diabetic foot.Methods A total of 115 patients with type 2 diabetic foot were randomly divided into treatment group (55 cases) and control group (60 cases).Salvia miltiorrhiza polyphenols and collagen sponge treatment group were treated with conventional treatment plus type 2 diabetes treatment of salvia miltiorrhiza polyphenol combined with collagen sponge;4 weeks as a treatment course, observation of 8 weeks, ulcer and other adverse reactions were recorded and compared.Results After 4 weeks of treatment, 17 cases (30.91%) with 30% or more reduction in foot ulcer area in treatment group,33 cases (60.00%) after 6 weeks treatment and the number of cases with 30% or more reduction in foot ulcer area,49 cases (89.09%) after 8 weeks of treatment, and the number of cases and the proportion of cases with 30% or more decrease of ulcer area in the control group after 4, 6 and 8 weeks were 12(20.00%), 22 (36.67%) and 39 (65.00%).There was no statistical difference between the two groups for the healing time of foot ulcer at three time points.After 8 weeks of treatment, the cure rate was 38.18% in salvia miltiorrhiza polyphenol combined with collagen sponge group. The effective rate was 50.91% and 45.00% for the two groups, the difference was not statistically significant; while the total effective rate was also significantly higher(89.09% vs.65.00%,P<0.01).Conclusion Salvia miltiorrhiza polyphenol combined with collagen sponge has a good effect on diabetic foot treatment, especially it can improve the cure rate, which is superior to the routine therapy.

Objective To investigate the survival rate and the influencing factors in lupus nephritis (LN) patients with neuropsychiatric systemic lupus erythematosus (NPSLE). Methods Clinical characteristics and biochemical markers of 78 patients including 59 variances were analyzed. Patients were followed up from the onset of NPSLE to death. Patient survival rate was estimated by Kaplan-Meier method. Cox regression model was used to analyze influencing factors. Results Sixteen (20.5%) of 78 patients died of SLE or its complications. Infection was the main cause of death (31.3%). One-, 3-, 5- and 10-year survival rates were 83.2%, 81.7%, 76.7% and 76.7%, respectively. Hypertension (RR =6.965,95% CI:1.578-30.746, P= 0.010), pulmonary infection (RR=8.171,95% CI:1.954-34.177, P=0.004)and acute renal failure (RR=6.978,95%CI:2.063-23.609, P=0.002) were risk factors of mortality, while cyclophosphamide (CTX) impulse therapy (RR =0.130,95 % CI:0.031-0.541, P=0.005) and resolution of NPSLE (RR= 0.169, 95%CI:0.042-0.679,P=O.012)were protective factors. Conclusions Infection is the main cause of death in patients of LN complicated with NPSLE. Survival rate of LN patients with NPSLE in this study is lower than those of LN and NPSLE alone reported by other authors. Hypertension, pulmonary infection and acute renal failure are risk factors of mortality, while CTX impulse therapy and resolution of NPSLE reduce the mortality and improve the prognosis.
