Objective: To develop a resiliency scale for university students. Methods: Based on reference research and some similar foreign scales, the resiliency scale for university students, including 6 factors and 31 items, has been developed and its reliabilities and validities has been studied. Results: The ? coefficients of the total and 6 subscales was 0.6383-0.8594; the split-half reliability of the the total and 6 subscales was 0.6334-0.8600. A good construct validity was found by some indexes(?2/df=2.27,RMSEA=0.048,GFI=0.8991,IFI=0.9006) demonstrated by confirmatory factor analysis. The scores of this scale had significant correlations with SCL-90 scale. Conclusion: A good psychometric feature of the scale has been demonstrated.

Objective To explore a better method for establishing rat model of simultaneous (liver)-kidney transplantation and the prevention of complications after transplantation.Methods In the donor operation, the liver and the right kidney were flushed with 0-4 ℃ sodium lactate Ringer’s (injection) through aorta, and en bloc resection of organs of right kidney, liver, pancreas, intestines, and spleen were done. Preparation was performed in the preservation solution. During the recipient (operation), all the blood vessels were reconstructed with cuff methods. The bile duct was anastomosed using a simple inside bracket. Operation of connecting ureter attached part of bladder with the bladder was conducted.Results One hundred and ten simultaneous liver-kidney transplantations including 50 (preliminary) experiments were carried out. Eighteen recipient rats died in the preliminary experiments. Five recipient rats died in the formal experiments and all the remaining had survived for more than 30 days. The successful rate of formal transplantations was 91.7 %.Conclusion This kind of rat model of simultaneous liver-kidney transplantation is simple. The time for blood vessel anastomosis and (anhepatic) stage was reduced. Complications such as stenosis were avoided. Preparation before operation, manipulation after operation and management after operation can affect the establishment of the model.

Objective To determine the optimal volume of plasma that should be used to perfuse through the portal vein (PV) to washout preservation fluid in retrograde reperfusion during liver transplantation.Methods The clinical data of S0 patients who underwent orthotopic liver transplantation (OLT) using retrograde reperfusion via the inferior vena cava (IVC) in our hospital from January 2011 to October 2013 were retrospectively analyzed.The patients were divided into two groups based on the volume of plasma infused via the PV to flush out the preservation fluid.Group 1:27 patients who received 400 ml,and Group 2:23 patients who received 1 200 ml.The preoperative and intraoperative data of the two groups were compared and analyzed.The serum concentrations of K+,Na+,Ca2+,mean arterial pressure (MAP) and pH were continuously monitored in the transplant recipients at different time points during liver transplantation.In addition,for patients in Group 2,the serum K +,Na + and Ca2 + concentrations in the samples of effluent fluid from the liver grafts were collected via the anastomotic stoma of the infrahepatic IVC and measured after infusion of 200 ml,400 ml,600 ml,800 ml,1 000 ml,or 1 200 ml of plasma.Results There were no significant differences in the preoperative and intraoperative data between the two groups.The plasma concentration of K + in Group 1 was significantly higher than that of Group 2 at 1 min after PV revascularization (T3) [(4.31 ± 0.54) mmol/L vs (3.96 ± 0.58) mmol/L,P ＜ 0.05],while the pH was significantly lower in Group 1 than that of in Group 2 (7.26 ± 0.02 vs 7.30 ± 0.04,P ＜ 0.05).The plasma Na + and Ca2 +concentrations,as well as the MAP,were not significantly different between the two groups at this time point.In group 2,no significant changes were observed in Ca2+ concentration in IVC blood following perfusion of 200 ml plasma.The insignificant changes in Na + after perfusion of 400 ml of plasma and for K + after 800 ml of plasma (P ＞ 0.05).Conclusions The electrolyte concentrations,blood pressure and arterial blood pH were fairly normal after resuming flow with PV revascularization after a perfusion volume of 800 ml of plasma.This volume was the most appropriate perfusion volume,balancing its effectiveness with economy to wash out any UW solution during OLT using retrograde reperfusion.

Objective To investigate whether transplantation of embryonic stem cell-derived cardiac myocytes (ESCMs) directly into the infarcted myocardium could improve the cardiac function in the rats.Methods Cell culture medium with or without ESCMs was injected into the borders of car- diac scar tissue one week after experimental infarction.Cardiac performance was evaluated 4 weeks later by means of echocardiography after ESCMs (n=16) or medium (n=12) injection.Results Im- munostaining confirmed the presence of?-actinin,?-MHC,and cTnI in the beating EBs.RT-PCR analysis of EBs revealed the expression of cardiac-specific genes,including cardiac Nkx 2.5,GATA-4 and?-MHC.ESCMs implantation significantly improved fractional shortening compared with medium- treated hearts (P

Objective To evaluate the CT findings and classification of the Le Fort fracture. Methods Sixty-two cases with Le Fort fractures were studied with thin-slice high-resolution CT scanning and analyzed with three-dimensional(3D)imaging reconstruction.Results Of the 62 patients,10 had Le Fort type Ⅰ fracture,9 had Le Fort type Ⅱ fracture,8 had Le Fort type Ⅲ fracture,and 35 had various combinations of the three types of Le Fort fractures,including 18 Le Fort Ⅰ+Ⅱ fracture,7 Le Fort Ⅰ+ Ⅱ+Ⅲ fracture and 10 Le Fort Ⅱ+Ⅲ fracture.Fifty-five cases had associated multiple fractures in the maxillofacial region.On 2D CT images,Le Fort fracture manifested as multiple and complex fractures. Though 2D image was better than 3D image in accurately defining tiny fractures and fractures of deep structures,the diagnosis of Le Fort fracture could not be correctly made solely on 2D image.3D CT clearly and stereoscopically demonstrated the entire shape and orientation of Le Fort fracture,thus facilitating the correct classification of Le Fort fracture.Conclusion 3D CT image is important in providing information about the space relationship of Le Fort fracture,thus very valuable for the preoperative planning.

Objective To investigate the possible mechanism of the gap junctional influence on the change in permeability of the blood-brain barrier(BBB)after reperfusion subsequent to cerebral ischemia.Methods In the test laser scanning confocal microscope(LSCM)was used to investigate the change of Cx43 levels and distribution.The MCAO/R model was induced using intraluminal suture technique first described by Longa with a little modification.A total of 60 Wistar rats were divided into 4 groups:the sham-operation group,control group,octanol-treatment group and DMSO vehicle control group. Control group were further divided into seven subgroups at different time points of reperfusion after middle cerebral artery occlusion.To observe the change in permeability of BBB,Evans blue(EB)in the brain tissue was surveyed by the means of EB fluorescent quantitation.Octanol-treatment group and DMSO vehicle control group were done at the point of the peak of permeability of BBB.Octanol,the specific blocker for gap junctions(GJ)was used in an intervention study.To compare the amount of EB with the same point of groups,the influence of octanol on BBB permeability was investigated.Results At 3 h of reperfusion after cerebral ischemia for 2 h,the permeability of BBB began to increase,reached the peak at 24 h of reperfusion and was still elevated at 72 h.The Cx43 expression formed into bigger plague and remained linear disposition in the penumbra after reperfusion subsequent to cerebral ischemia.Octanol group was done at 24 h of reperfusion after cerebral ischemia.The amount of EB of octanol group((4.924?0.296)?g/g)was significantly lower than that of corresponding operation control group(5.543?0.506)?g/g.Conclusions (1)Cx43 expression is concentrated around vessels in brain.The Cx43 forms into bigger plague and the function maybe strengthens after reperfusion.Gap junction might aggravate the disruption of BBB.(2) Octanol,the specific blocker of gap junctions,could effectively prevent the permeability of BBB from increasing and has a protective effect on BBB.

Hepatectomy is the treatment of choice for huge ( ＞ 10 cm) hepatocellular carcinoma.However,the resection is more difficult and risky due to a huge space occupied by the tumor and vascular invasion.Precise hepatectomy is a new concept of liver surgery in the 21st century.The goal of which is the least invasive,most parenchymal preserving and optimal recovery.A male patient with a huge hepatocellular carcinoma (diameter =22.5 cm) received precise hepatectomy in the Department of Hepatobiliary Surgery of Fuzhou General Hospital of Nanjing Military Area.By using the digital medical technology and procedure of liver surgery planning system,the tumor and the whole structure of the liver were three dimensionally reconstructed,and the planning of resection was made.During surgery,the right liver artery and the right.porta hepatis were ligated and the right hemihepatic vessels were occluded.We accomplished right hepatectomy by accurate resection according the precisely planned preoperation,with less bleeding or no bleeding surgical field and rapid recovery.

To analyze the correlation of pharmacokinetic/pharmacodynamic (PK/PD) of Chinese materia medica (CMM) based on the multi-components and multi-targets, through the example of demonstrative research, we brought forward some innovative strategies. The research requires to use a medicated serum in parallel at a pathologic state. The experiments included the determination of multi-components PK parameters, the establishment of serum dynamic fingerprints and multi-targets PD models, the research on PK/PD binding model, the selection of the analytic program, the representation of internal relations among the concentration, time, and effect in the effective component group, the analyses on the correlation between fingerprint and PD, the tracing of the rule of PD from the chemical fingerprints and metabolic fingerprints, and the construction of a spectrum which could represent the characterization of the correlation between the retention time and the effect and the characterization of dose-effect fingerprint spectrum of the correlation between peak area growth and effects. The multi-dimensional characteristics of fingerprint-pharmacophore fingerprints (feature effect peak and dose-effect fingerprint spectrum)-fingerprint spectrum of PK are integrated, processed, and edited and a multi-dimensional image of "active integration fingerprint" in the active component group was built. A new research method on the combination of the PK/PD of CMM was explored. Only by this way, we will really understand the interaction in active component group in vivo and clearly explain the material base which truly works.

Objective To explore the effect of pre-hospital nursing intervention in the new regional cooperative rescue model on treatment delay and the therapeutic effect in patients with myocardial infarction.Methods From January 2012 to May 2014,158 patients with acute myocardial infraction (AMI) were selected.Patients were divided into two groups,intervention group and control group,The first medical contact to balloon(FMC-to-B) time,referral time,cardiac function were analysed.Results Mean FMC-to-B time [(94±21)min vs.(102±23) min],referral time in nursing intervention [(5±3) min vs.(9±4) min)] were significantly shorter than those in control group (t=2.14,6.67,P＜0.05).After a month compared with control group,LVEF was increased [(54.8±6.9)％ vs.(48.8±6.9)％],and LVED was deceased [(50.1±8.2) mm vs.(50.5±5.6)mm] in intervention group.Conclusions Pre-hospital nursing intervention can decrease the FMC-to-B time,which could improve the cardiac function.

Objective:This study was conducted to evaluate whether or not immediate breast reconstruction influences quality of life and patient body image satisfaction outcomes among Chinese women with breast cancer compared with modified radical mastecto-my. Methods:Sixty patients with breast cancer and were operated from July 2011 to July 2012 in Cancer Institute&Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College were included. These patients were divided into two groups:Ⅰ(30 patients) underwent modified radical mastectomy andⅡ(30 patients) underwent mastectomy with immediate breast reconstruction. Pa-tient satisfaction with breast reconstruction was evaluated by functionally assessing cancer therapy-breast cancer scale (FACT-B) and the scales that we designed. Results:No significant differences were observed between the two groups in terms of baseline characteris-tics, histopathological characteristics, and incision conditions (P>0.05). The patients in groupⅡ(immediate breast reconstruction) ex-hibited improved body image satisfaction outcomes (41.1 ± 10.8 vs. 33.2 ± 8.8, P=0.003);this difference was still observed after adjust-ment for confounding factors was performed by multiple linear regression. No significant difference was found between the two groups in terms of total FACT-B score and psychological evaluation score (P>0.05). Conclusion:Chinese women who prefer immediate breast reconstruction exhibited an improved body image satisfaction.
