Objective To identify objective methods for medical service performance evaluation,and means to improve the efficiency of medical services.Methods By means of collection of medical records from 10 tertiary hospitals in Yunnan in 2012,and Diagnosis-related groups of Beijing version(BJDRGs)as a risk-adjustment tool,medical service performance was made to such hospitals.Results The capacity,efficiency and medical safety of hospital of the hospitals were subject to a comprehensive evaluation of their medical service capabilities.In terms of discharged inpatients and total weight,hospital A were found to be the highest(77 458 cases,104 227.5 respectively),and hospital I the lowest(25 450 cases,38 162.28)among these hospitals in 2012; compared with other hospitals,DRG groups of hospitals A,b and D were found higher,while the case mix index(CMI)of hospitals e and I were higher.The expenditure index of hospital C is the lowest(0.9359,0.8514); the mortality in cases of low risk of hospitals B,c and D were the lowest,while hospital F was the highest.Conclusion DRGs as a risk adjustment tool,can significantly improve the reliability,science and continuity of medical service performance evaluation,providing reliable basic data for hospitals accreditation in Yunnan.

Objective To explore the anxious condition of nurses and correlative factors,and to explore the relationship between the nurses' anxiety and the correlative factors,so that can help the management echelon and nurses to correctly understand the relationship of anxiety and pressure,and control and handle the anxiety problem of nurses fundamentally,and improve the physical and mental health,work efficiency and nursing quality of nurses. Methods A questionnaire investigation was conducted in 85 nurses from a certain hospital in Harbin about the anxiety,life events,work stressor and the relationship between them. Results 30 nurses had anxiety(the anxiety group),another 55 nurses showed no anxiety(the nonanxiety group).The comparison of items in life events inventory showed that great difference existed in pregnancy,addition of new family members,the difficulty of training their children,property damage or being stolen,living apart with the spouse,magnificent changes of the life style,having got severe illness or wound.In the aspect of work sttessor scale,professional and career issues,workload and allocation of time,working environment,patient care and interaction showed significant difference.The work pressure was significantly associated with the level of anxiety. Conclusions Our finding suggest that effective stress management strategies should be implemented to reduce or eliminate work pressure of nurses,carry out training to improve the self-regulation ability of nurses,and if necessary biofeedback therapy can be introduced.

Postoperative peritoneal adhesion represents a major complication of surgery. Recently, the angiogenesis which cyclooxygenase-2 enzyme induced was found to play an important role in the adhesion synthesis. This review summarized the relationship between COX-2 induced angiogenesis and peritoneal ad- hesion.

It is now clear that both endogenous and exogenous sources of nitric oxide(NO) exert important modulatory effects on cardiac mitochondrial function.There is also growing evidence that NO can be produced within the mitochondria themselves.NO can influence respiratory activity,both through direct effects on the respiratory chain or indirectly via modulation of mitochondrial calcium accumulation.At pathological concentrations,NO causes irreversible alterations in respiratory function and also interacts with reactive oxygen species(ROS) to form reactive nitrogen species(RNS),which may further impair mitochondrial respiration and even lead to open the mitochondrial permeability transition pore and induce cell death.Diabetes,aging,myocardial ischemia,and heart failure are all associated with altered ROS generation,which can alter the delicate regulatory balance of effects of NO in the mitochondria.

Objective To study the correlation between chronic gastritis with benign mucosal nodular-change,Helicobacter pylori(H.pylori)infection and lymphoid follicles infiltration.Methods During July 1,2004 to June 30,2005 patients with chronic gastritis and benign mucosal nodular-change were identified by chromo-endoscopy with anabrosis indigo carmine staining at the antrum.Multiple biopsies were obtained for H.pylori detection with quick test and for pathology examination of mucosal lymphoid follicles formation and lymphocyte infiltration,as well as H.pylori infection.Results The patients were divided into nodular gastritis group,atrophy gastritis group and verrucous gastritis group with mean age of(31.00?11.62),(58.61?12.14)and(51.29?12.99)years old,respectively.The patients with nodular gastritis were the youngest(P

Objective To explore the correlation of the apoptosis of peripheral blood mononuclear cell (PBMC) with plasma 8-iso-prostaglandin F2? (8-iso-PGF2?) level in order to confirm the peroxidation damage of hyperbilirubinemia in neonates with jaundice.Me-thods One hundred and twenty-nine neonates who were 2 to 7 days old were divided into 4 groups:slight jaundice (43 cases),moderate jaundice (38 cases),serious jaundice (18 cases),and healthy control(30 cases)groups.Plasma 8-iso-PGF2? levels were assayed by enzyme immunoassay(EIA),and the apoptosis rates of PBMC were determined by flow cytometry.Results 1.There was no significant difference in the apoptosis rate of PBMC between normal and slight jaundice neonates (P=0.108);apoptosis rate of PBMC was increasing with the aggravation of jaundice.2.Plasma 8-iso-PGF2? level in normal neonates was 14.74?6.71 ng/L,there was no difference between normal neonates and neonates with slight jaundice(P=0.502).Plasma 8-iso-PGF2? levels in neonates with moderate and serious jaundice were much higher(Pa=0).3.Positive correlation existed between plasma 8-iso-PGF2? level and PBMC apoptosis rate (r=0.602 P=0).Conclusions Hyperbilirubinemia can induce peroxidation damage,resulting in increase of PBMC apoptosis.Plasma 8-iso-PGF2? level can accurately eva-luate the peroxidation damage in neonates with jaundice.

Objective To evaluate the clinical features and early management of combined thoracoabdominal injury (CTI).Methods A retrospective study was carried out in 29 cases with CTI treated surgically.There were 21 cases with penetrating injuries and 8 cases with blunt injuries.All cases were associated with penumothorax and/or hernothorax at various degrees and 13 cases complicated with shock.In this study thoracotomy was performed in 17 cases,laparotomy in 6 cases,thoracotomy plus laparotomy in 5 cases and combined thoraco-laparotomy in 1 case.Results The injury severity score in this series was (40.16±15.23) scores.Four cases were died from hemorrhagic shock (2 cases),pericardial tampenade(1 case) and multiple organ failure(1 case).Conclusions CTI has high mortality rate,and the most frequent cause of death is hypovolemic shock.The operative approach is based on individual injury condition.Early diagnosis and timely surgical intervention are key to improving the cure rate and reducing mortality in severe CTI.

Objective:To study the influernce of circadian genes hClock and hBmal1 on the chemosensitivity of SGC-7901 cells. Methods: SGC-7901 cells were cultivated under continuous darkness in vitro.The expression levels of the two main circadian genes hClock and hBmal1 at the different time were determined by real-time polymerase chain reaction(PCR). Docetaxel was administered at the peak and nadir time point respectively. The inhibition of SGC-7901 cell proliferation was measured using a CCK-8 kit. Result:The expression of circadian genes hClock and hBmal1 varied at different times, as shown by real-time PCR. The expression of circadian genes hClock and hBmal1 showed Phase oseillation. The maximum expression of hClock and hBmal1 mRNA was at 20:00. whereas their minimum expression was at 08:00. The inhibition ratio of docetaxel to SGC-7901 cells at the maximum expression of hClock and hBmal1 genes was lower than that at the minimum expression. Conclusion:Circadian Genes hClock and hBmal1 can reduce the drug sensitivity of SGC-7901 cell line to docetaxel in vitro.
