Objective To investigate the association of occupational stress,social support,type D personality and physical health of nurses.Methods Cross-sectional study design was adopted.We used cluster sampling to investigate 1 287 nurses serving in one tertiary hospital and two second-class hospitals in Guangzhou.The questionnaire was anonymous answered.The content of questionnaire included the demographic data,occupational stress of nurses,social support,type D personality and physical health,etc.SPSS 13.0 was used for statistical analysis,including descriptive analysis,Pearson correlation analysis and path analysis.Results 1 192 of questionnaires were effective.The occupational stress was negatively related with the physical health status and social supports,and social support was positively related with the physical health status.The type D personality was negatively related with social supports and the physical health status,while positively related with occupational stress.Conclusions Occupational stress can make directly negative effect on the physical health.Social support has a directly protective effect on physical health.Type D personality makes direct and indirect negative effect on the physical health of nurses.

Objective To analyse reperfusion arrhythmias in AMI patients treated by direct PCI. To investigate prevention and treatments so as to elevate operation achievement ratio.Methods One hundred and seventy six AMI patients underwent direct PCI; of the 176 patients, 56 presented reperfusion arrhythmias. Observations were made in the context of the different arrhythmias, relation between the time onset of the arrhythmias after reperfusion, relation of infarct size number of the involved vessels and the infarct size to the arrhythmias. Results PCI performed with six hours after AMI showed much higher incidence of arrhythmias than PCI performed six to twenty four hours after AMI (P0.05).Conclusions Reperfusion arrhythmias were commonly seen in AMI patients treated by direct PCI. Early prevention and detection with appropriate treatment is the key to elevate survival rate leading to a better prognosis.

Objective To explore the relationship between work-family conflict and turnover inten-tions in nurses and find out the key points to reducing turnover intentions by releasing individuals' work-family conflict. Methods Cross-sectional study method was used in this investigation. By using cluster sampling method, 1287 nurses from some top-level and third-class general hospital were investigated. The questionnaire of work-family conflict and turnover intentions scale were used in this research and the re-suits underwent analysis. Results The score of turnover intentions in nurses was positively correlated with the level of their work-family conflict (r=0.233,P<0.01). Stress,behavior and time dimension were related factors of turnover intentions(r=0.243,0.191,0.176,P<0.01 ).After control of demographic factors, the turnover intentions deviation that can be explained increased by 7%. Conclusions The score of work-family conflict is one of the predicators of turnover intentions. A developing measure should be taken to reduce turnover intentions by releasing work-family conflict in nurses.

BACKGROUND: Whether ceramic alloy can be reused after casting depends on its chemical composition, microstructure, castability, as well as mechanical property. However, the effects of recasting on the composition and microstructure of Ni-Cr ceramic alloys are poorly understood. OBJECTIVE: To investigate the effects of recasting on the composition and microstructure of Ni-Cr ceramic alloys. DESIGN, TIME AND SETTING: In vitro materials observation. The experiment was performed at the Department of Prosthodontics, Affiliated Stomatological Hospital, Fujian Medical University, Instrumentation Analysis and Measurement Center, Fuzhou University, from June to August 2007. MATERIALS: The Ni-Cr ceramic alloys were recast 6 times in argon protection to obtain testing sample with diameter of 30.0 mm, thickness of 1.0 mm and side length of 10.0 mm, thickness of 1.0 mm, namely generation I VI. Simultaneously, the sample produced by initial alloy was called generation 0. METHODS: The original alloy and each generation square plates were analyzed by X-ray fluorescence spectrometry (XRF) for qualitative and semi-quantitative analysis. The microstructure and the phase structure of original alloy and each generation castings which had been polished by buffing machine were observed and analyzed by metallographic microscope and X-ray diffractometer (XRD). MAIN OUTCOME MEASURES: Contents of chemical composition, shrinkage cavity, porosity and inclusion, and distribution of XRD patterns. RESULTS: The results of XRF indicated that there were no significant difference on the main composition (Ni, Cr, Mo, Al, Be) among the Ni-Cr ceramic alloys multiple recast 0-6 times in argon protection and accorded with the demands. The metallographic structure of Ni-Cr ceramic alloys were dendritic eutectic structure, but the size of dendritic crystal grain in the casting coarsening, shrinkage cavity, porosity and inclusion gradually increased, with the increase of multiple recast times. The phase structure of Ni-Cr ceramic alloys were Ni-base solid solution (face-centered cubic lattice structure) and the chromium was widely distributed in the nickel base. There were neither significant difference of phase structure nor the new phase structure appeared among the Ni-Cr ceramic alloys multiple recast 0-6 times. CONCLUSION: There is no significant difference of main composition and phase structure between original alloy and each generation castings in argon protection. With the increase of recast times, the size of dendritic crystal coarsening, shrinkage cavity, porosity and inclusion gradually increased.

Objective To investigate the abnormal expression of proto-oncogene YES-associated protein (YAP) in gastric cancer tissues in the elderly and its correlation with poor prognosis.Methods Clinical data of 80 elderly patients with gastric cancer treated in our hospital from March 2011 to October 2014 were statistically analyzed.Results The positive expression rate of YAP was significantly higher in gastric carcinoma than in adjacent tissues [71.3％ (57/80) vs.13.8％ (11/80),P＜0.05].The positive expression of YAP were significantly associated gastric tumor size,tumor stage,invasion depth and lymph node metastasis (all P＜0.05),but had no correlation with tumor differentiation (P＞0.05).The 5-year survival rate was significantly lower in patients with YAP-positive expression than in patients with YAP-negative expression (P ＜ 0.05),but the differences in 1-year,3-year survival rates were not significant between the two groups (all P＞0.05)The YAP expression,tumor stage,lymph node metastasis were significantly associated with the prognosis of gastric cancer in patients (all P＜0.05).Conclusions YAP-positive expression rate is significantly higher in gastric cancer tissues than in adjacent tissues in the elderly,which indicates poor prognosis of patients with gastric cancer.

_ Objective_ To evaluate the efficacy of unilateral subtotal adrenalectomy in the treatment of bilateral adrenal solitary neoplasma causing Cushing's syndrome and to elaborate the therapeutic principle. Methods From 2007 to 2013, a total of ten patients were diagnosed with Cushing's syndrome caused by bilateral solitary adrenal neoplasma. We compared patients'clinical symptoms, hormone profiles, biochemical and metabolic parameters, and imaging data before and after the surgery. Five of them chose the optimal neoplasma based on the lateralization ratio of adrenal venous sampling result and the other 5 patients chose the optimal neoplasma based on the diameter of the mass reflected by the computed tomography result and were then operated. Results After the unilateral subtotal adrenalectomy,the24-hour urinary free cortisol decreased significantly(P<0.05)and the midnight serum cortisol level also significantly reduced(P<0. 01). Plasma adrenocorticotropic hormone level increased significantly(P<0. 01). Nine patients of them did not need contralateral adrenalectomy and one patient received contralateral adrelectomy because of the remnant of Cushingnoid symptoms. Conclusion Unilateral subtotal adrenalectomy is an effective and safe way to treat Cushing's syndrome caused by bilateral solitary neoplasma.

To investigate the distribution of the genes of two major metallo-beta-lactamases (MBL; i.e., IMP and VIM) and class 1 integrons (intI) in the clinical imipenem-resistant Pseudomonas aeruginosa, a total of 65 isolates, from a university hospital in Sichuan between December 2004 and April 2005 were screened for MBL genes by PCR using primers specific for bla ( IMP-1 ), bla ( VIM ) and bla ( VIM-2 ) genes. The MBL-positive isolates were further assessed for class 1 integrons by PCR using specific primers. The nucleotide sequences of several PCR products were also determined. The results revealed that the bla ( VIM ) gene was found in 81.5% (53/65) of all isolates, bla ( VIM-2 ) gene was found in only 1 isolate and the intI gene was observed in 45.3% (24/53) of bla ( VIM )-positive isolates. One isolate carried simultaneously both bla ( IMP-1 ) and intI genes, and to the best of our knowledge this is the first report of such isolate in southwest China. These observations highlight that the genes for VIM beta-lactamase and class 1 integrons were predominantly present among the imipenem-resistant P. aeruginosa tested, confirming the current widespread threat of imipenem-resistant, integron-borne P. aeruginosa.

New strategies are needed for prevention of Pseudomonas aeruginosa (P. aeruginosa) infections, a widespread disease caused by P. aeruginosa with strong drug resistance. The immunoprotective capacity of the receptor of autoinducers protein LasR/RhlR was examined in the BALB/c mice. At first, specialized expression plasmids were developed to facilitate expression of LasR/RhlR proteins in Escherichia coli (E. coli). Then, biofilms were grown from clinical isolated P. aeruginosa PA0305 to investigate the relative contributions of cell signaling for biofilm formation. Morphological characters of biofilm were quantified using Image-Pro Plus software. Fluorescence analysis demonstrated that cell signal molecule LasR/RhlR significantly (P ＜ 0.05) influenced development of P. aeruginosa biofilm. Active immunization of mice with LasR/RhlR was found to provide significant protection against homologous challenge with P. aeruginosa in mice lungs. In 10 days after lungs inoculation, the bacterial clearance rate of the immunized mice was clearly higher than that of non-immunized groups on the basis of microbiological and histological assays. The protective effects of immunization with LasR and Rh1R together were the same as the result of LasR or Rh1R immunized mice alone. These data indicate that the manner ofLasR, Rh1R or both is an important determinant of immunoprotection in mice lungs infection.
