Objective Hepatocyte growth factor (HGF) has been proposed to be used as an endogenous cardioprotective agent. The aim of the present study was to investigate the anti-apoptosis effect of HGF on rat cardiomyocytes after being irradiated by single dose gamma ray. Methods The study was performed using primary cell cultures of cardiomyocytes isolated from hearts of new-born rats. After being cultured for 72h in vitro, cardiomyocytes were irradiated with gamma ray in a single dose of 20Gy. In the HGF treated groups, cells were incubated with HGF in the dose of 20 and 40ng/ml 3h prior to irradiation, respectively. At 48h post-irradiation, the concentration of LDH in the supernatant of cell culture was determined. Apoptosis and cell cycle were determined with flow cytometry. Results LDH concentration in the supernatant of cell culture of irradiated cardiomyocytes was increased significantly compared to that of un-irradiated cells (P

Capital logic is the first to be avoided in the construction of medical humane service system,for it is capital logic that manifest the current technical and commercialized time with an "indifferent" characteristic.Capital logic originated and distended from the western culture.As another spiritual pursuit and wisdom,traditional Chinese philosophy provides us with significant ideological resources and helpful revelation for improving medical humane service in current circumstances.

Objective To observe the therapeutic effects and complication of combined endoscopic trerapy of the acute biliary pancreatitis(ABP). Methods 70 cases of acute biliary pancreatitis were treated in our hospital in recent 7 years.37 cases(group E) admitted undergone emergency endoscope procedure were treated with endoscopi- cretrograde cholongiopancreatography ( ERCP ), endpscopic sphincterotomy ( EST ) and endoscope naso-biliary drainage(ENBD) in 24h after be hospitalized. 33 cases(group C) were treated with conservation treatment or opera-tion treatment. Results Achievement ratio of endoscopic management was 92 %. There was no severe complication or mortality in group E. The duration of symptoms and hospitalization in endoscopy group were significantly shorter than those in group C(P<0.01). The change of serum and urine amylase was not significant between two groups in the first day after treatment(P > 0.05). But the serum and urine amylase of group E were significantly lower than those in group C in the second day(P< 0.05) and more significantly lower in the third day after treatment(P< 0.01 ). Conclusion Early endoscopic therapy is safe and effective in ABP patients. It is a valuable method to treat a- cute biliary pancreatitis.

Objective To investigate the early diagnosis and rational treatment of traumatic retroperitoneal hematoma(TRPH). Methods Retrospective analysis was done on the clinical data of 96 cases of TRPH admitted in our hospital in the past 10 years. Results Eighty two patients received operation, of whom,73 combined with other celiac organ injuries.The other 14 patients were treated by non surgery.Two patients combined brain trauma and 1 with hemorrhagic shock died during operation,and 2 died of multiorgan failure postoperatively. Conclusions Early diagonsis depends on clinical appearance, abdominocentsis, B ultrasonography and CT. Operation should be done immediately,if the patient has the following condition:(1)apparant hemorrhagic shock after blunt trauma;(2) comfirmed celiac viscera trauma or blood vessel trauma;and (3)retroperitoneal hematoma caused by penetric trauma. Kidney surrounding hematoma or hematoma in pelvis area needs no immediate operation.

Objective To evaluate the therapeutic effect of duodenoscopy in the early treatment of acute biliary pancreatitis (ABP).Methods Twenty ABP cases admitted from Oct.2000 to Mar.2004 received emergent endoscopic retrograde cholongiopancreatography (ERCP), sphincterotomy (EST) plus endoscopic lithotomy and endoscope naso-biliary drainage (ENBD).Other 16 cases were treated with conservative therapy or open surgery.Results Successful rate of endoscopic management was 95%.There were no severe complications nor mortality in this group.The duration of symptoms and hospitalization in endoscopy group were significantly shorter than control group ( P

Objective To study the value of microwave coagulation therapy for liver malignant tumors.Methods Under local anesthesia,19 cases with hepatic malignant tumors treated with microwave knife under CT-guided.Results There were totally 23 tumors in 19 cases,13 tumors with≤3.5 cm in diameters were destroyed absolutely after the first treatmet,10 tumors among them were followed-up for 6-12 months and no recurred.10 tumors with＞3.5 cm in diameters treated at multiple points or angle,3～6 months later,CT showed that the tumors were destroyed completely in 6 and mostly in 4,by the hot condensate treatment secondly,3 tumors of 4 were destroyed completely 3 months later.There were no obvious complications.Conclusion The therapeutic effect under CT-guided microwave coagulation therapy for liver tumor which are ≤3.5 cm in diameter of the tumors is very reliable,the tumors＞3.5 cm in diameter can be destroyed mostly or completely by microwave treatment.

Objective The objective of this study was to investigate the miR-345 expression level in non-small cell lung cancer(NSCLC)tissue and its potential clinical significance.Methods Real-time PCR was conducted to evaluate the expression of miR-345 in NSCLC tissues in 98 samples and cell lines.Then the association between tissue miR-345 expression level and clinical outcomes was further analyzed.Results The expression level of miR-345 was significantly decreased in NSCLC tissues and cell lines when compared to the controls(P<0.05).miR-345 expression level in NSCLS tissues was associated with various clinicopathological parameters including LN metastasis(P<0.001),distant metastasis(P=0.028),TNM stage(P=0.004)and grade(P=0.011).In addition,the NSCLC patients in the low miR-345 expression group showed significantly shorter overall survival time than that in the high miR-345expression group(P=0.021).Multivariate analysis showed that the expression of miR-345 was an independent risk factor for NSCLC(HR=3.897,95% CI:2.263~10.440;P=0.012).Conclusion The expression level of miR-345 was decreased in NSCLC tissues as well as cell lines compared with normal controls.Low miR-345 expression in tissues was associated with progression and poor prognosis of NSCLC.These results indicate that miR-345 may be a novel prognostic marker in NSCLC.

Objective To evaluate the therapeutic effect of endoscopic treatment for acute biliary pancreatitis. Methods Thirty-six cases of acute biliary pancreatitis were treated in our hospital in recent 4 years. Tweent cases (group E) underwent emergency endoscopic retrograde cholongiopancreatography(ERCP),endoscopic sphincterotomy(EST) and endoscopic naso-biliary drainage (ENBD) within 24h of hospitalization; 16 cases (group C ) were treated conservatively or by operation. Results Successful rate of endoscopic management was 95.24%. There were no severe complications nor mortality in group E. The duration of symptoms and hospitalization in endoscopic group was significantly shorter than those in group C(P0.05). But the serum and urine amylase in group E were significantly lower than those in group C in the second day(P

Objective To investigate the current situation and related risk factors of healthcare-associated infection (HAI),so as to provide evidence for making prevention and control measures of HAI.Methods On November 26, 2014,a combination method of bedside visiting and medical record reviewing was adopted to survey HAI status, pathogen examination,and antimicrobial application in all hospitalized patients in a tertiary first class military hospi-tal.Results A total of 1 657 hospitalized patients were investigated,66 patients developed 71 times of HAI,HAI rate and HAI case rate were 3.98% and 4.28% respectively.The top 4 departments with HAI prevalence rates were departments of neurosurgery (24.49%),hematology(19.05%),cadre ward(13.73%),and burn surgery (10.91 %).The top 5 HAI sites were lower respiratory tract (40.85%),urinary tract(23.94%),upper respirato-ry tract(12.68%),surgical site(9.86%),and gastrointestinal tract(5.63%).Of 66 cases of HAI,39 (59.09%) patients sent specimens for culture,a total of 48 pathogens were cultured,the major isolated bacteria was Esche-richia coli (n = 10,20.84%),followed by Staphylococcus aureus ,Klebsiella pneumoniae ,and Pseudomonas aeruginosa ,each was 7 (14.58 %)respectively.The usage rate of antimicrobial agents was 34.40%,specimen de-tection rate in patients receiving therapeutic and therapeutic+prophylactic antimicrobial agents was 59.28%.Risk factors for HAI were age <2 years old or >60 years,with respirator,tracheotomy,urinary tract catheterization, arteriovenous catheterization,hemodialysis,and surgery,difference was significant(all P <0.05).Conclusion Mo-nitoring on key departments and key sites of HAI should be strengthened,antimicrobial agents should be used rationally based on pathogenic detection results,specimen pathogenic detection rate should be improved,and effective prevention and control measures needs to be taken according to the risk factors of HAI.
