This machine use first used in our hospital and it has been proved successfal.

Objective To evaluate results of surgical treatment for patients with acute type A aortic dissection using Sun’s operation and triple-branched stent graft. Methods According to the operation mode, thirty-three patients with type A aortic dissection were divided into Sun’s operation group (n=22) and triple branches aortic arch stent-graft placement op?eration (triple-branched) group (n=11). Preoperative examinations included cardiac ultrasound, aortic CT angiography (CTA), hepatic and renal functions and blood routine test in all patients. Intraoperative monitoring included the index about cardiopulmonary bypass and blood loss. The perioperative hepatic and renal functions and complications were also recorded. Survival and recovery rates were evaluated by follow-up between two groups of patients. Results There were six periopera?tive death in Sun’s group, and three patients died in triple-branched group. In triple-branched group, the intraoperative blood loss was significantly increased than that in Sun’s group [(3 586.4±2 926.8) mL vs. (2 630.5±1 821.2) mL, P<0.05]. Postoperative echocardiographic examinations revealed that the left ventricular size (LVEDd) and the aortic diameter were decreased while the left ventricular ejection fraction (LVEF) was elevated after surgery in Sun’s group [(50.9±6.9) mm vs. (55.0±7.5) mm,(28.2±1.6) mm vs. (48.8±11.0) mm, 0.620±0.031 vs. 0.469±0.104, P<0.05]. Whereas, only the aortic diame?ter was decreased after surgery in triple-branched group [(28.6±3.9) mm vs. (50.9±9.2) mm, P<0.05]. Kaplan-Meier surviv?al curve showed that five-year survival rate of Sun’s group was similar with that of triple-branched group (Log-rank χ2=0.095,P>0.05). At 5 year after operation, there were no significant differences in the recurrence of new aortic dissection, the incidence of cerebral infarction and mortality between Sun’s group and triple-branched group (P>0.05). Conclusion Sun’s operation can significantly decrease patient’s intraoperative blood loss and improve cardiac function. But its survival rate and long term results need advanced observation.

Objective To establish a headspace GC method for determination of residual organic solvents as methanol, ethanol,dichloromethane and n-hexane in trepibutone. Methods An external standard method was used. A DB-624 capillary column (75 m× 0.450 mm,2.55 μm) was used with a FID detector. The injector temperature was 200 ℃ and the detector temperature was 250 ℃ .The initial column temperature was 50 ℃ ,kept for 6 min,then raised to 200 ℃ at a rate of 20 ℃ ?min-1 and kept for another 12 min. Nitrogen was used as the carrier gas. The flow rate was 3. 0 mL ? min-1 . The headspace vials equilibrium temperature was 80 ℃ and the balance time was 30 min.The injection volume is 1 mL. Results A1l the solvents could be completely separated with good linear relationships.The average recoveries of the four solvents were 100.4% ( RSD =0.5%), 100.6%(RSD = 0.6%), 99.6% ( RSD = 0.8%), 98.7% ( RSD = 0.7%) ( n = 9),respectively. Conclusion The method is simple and accurate,and can be used in the determination of residual solvents in trepibutone.

Objectives To understand essential basis data availability for implementation of cost accounting in TCM hospitals. Methods Costs of a total of 1588 TCM hospitals were investigated by conducting the baseline survey via questionnaires in 2013. Results Departmental basic data (including ratio of office staff and entire staff, ratio of outpatient and inpatient departments in clinical department), and construction data for housing were well accessible, while utility fee and internal service data were not. Conclusion ①Public TCM hospitals need to improve and specify the basic cost data. ②Differences exit among different types and levels of hospitals in the availability of data. ③There are still difficulties in carrying out cost accounting in public TCM hospitals, which needs strong supports from all relevant departments.

Objective To assess systematically the effect of problem-based learning (PBL) versus traditional methods in nursing students.Methods Relative literature was searched by computer at home and abroad.according to the inclusion and the exclusion criteria,which were analyzed by RevMan5.2 software,and literature selection and repetition were used according to the Note Express software.Results A total of 9 studies of randomized controlled or not randomized controlled trial were brought into the study by random effects model.A total of 1 187 were collected into the study,574 in the experimental group and 613 in the control group.According to subgroup analysis showed by measurement scale,problem-based learning (PBL) can significantly improve the critical thinking ability of nursing students.The results had high stability and reliability.Conclusions PBL teaching method can significantly improve the critical thinking ability of nursing students,and provide a better learning method for clinical teachers and students,which is worthy of further promotion.

Many factors,especially perinatal asphyxia,can lead to varying degrees of hypoxia brain injury in fetus or newborns within perinatal period.So far,the mechanisms of neonatal cerebral damage caused by hypoxia during the perinatal period have not been clearly demonstrated,and there have no effective drugs or therapeutic methods to improve hypoxia-induced cerebral damage.This review focuses on the recent progress of zebrafish as a model organism of using in research of hypoxia brain injury,including the anatomic and behavior basis,model making,research strategies and the advantages of neurotrophic drug screening.The application of zebrish in the research of neonatal hypoxic brain injury is promising,and may provide a new tool as research in finding out the therapy strategies of hypoxic-ischemic encephalopathy.

ObjectivesTo investigate the expression of glucose regulated protein 78 (GRP78), CCAAT/enhancer binding protein homologous protein (CHOP) and cysteine asparate protease-12 (caspase-12) and neuronal apoptosis in the brain of zebraifsh larvae after hypoxia reperfusion, and the neuroprotective effect of taurine.Methods Five day old post-fertilization zebraifsh larvae were randomly assigned into 3 groups, control group, hypoxia reperfusion group (model group) and taurine group, and the taurine group was further divided into 3 subgroups according to different concentrations (1 mmol/L, 5 mmol/L, 10 mmol/L) with 100 zebraifsh larvae each. The behavior, recovery time and median survival time of those zebraifsh larvae after hypoxia with 1h reperfusion were observed and recorded. The pathological changes and apoptosis of neurons were detected by Nissl staining and terminal deoxynucleotidyltransferase-mediated dUTP nick end-labeling. The expression of GRP78, CHOP and caspase-12 in the brain of zebrafish larvae were detected by Western blot.Results Compared with the model group, the recovery time was shortened, the median survival time was extended, the Nissl stained neurons was increased and the apoptotic neurons were decreased in the taurine groups. GRP78, CHOP and caspase-12 were expressed in model group and taurine group. The expression of GRP78, CHOP and caspase-12 was much lower in taurine group than in model group.Conclusions Hypoxia reperfusion may induce endoplasmic reticulum stress and taurine may be neuroprotective against hypoxia reperfusion by down-regulating GRP78, CHOP and caspase-12.

Objective To discuss the relationship between serum 25-hydroxy vitamin D[25(OH)D] level and the severity of diabetic retinopathy in type 2 diabetes mellitus.Methods 1474 cases of type 2 diabetic patients were classified into three groups according to their severity of diabetic retinopathy, the non-diabetic retinopathy group(NDR group, n =640), the background diabetic retinopathy group(BDR group, n =494) and the proliferative diabetic retinopathy group(PDR group, n=340).640 healthy people with normal level of glycosylated hemoglobin(HbA1c) were selected as control group(NDM group, n=640).Disease duration, body mass index(BMI), systolic pressure, low density lipoprotein-cholesterol(LDL-C), HbA1c and 25(OH)D were detected and compared among groups.Results Disease duration and HbA1c were increasing significantly, and the levels were NDM groupNDR group>BDR group>PDR group(all P<0.05).The level of 25(OH)D was negatively related to disease duration and HbA1c (P<0.001), and it was negatively associated to the severity of diabetic retinopathy(r=-0.855,P<0.001).Conclusion The decrease of 25(OH)D level is closely associated with the severity of diabetic retinopathy in patients with type 2 diabetes mellitus, and it might be an important predictor for the severity of diabetic retinopathy.
