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 identify the sounces of occupational stress and explore the relationship between occupational slreas and social support for nurses in ICU.Methods A descriptive and correlation design was used in this study.From July to October in 2007,159 nurses from 8 ICU and 160 nurses from common wards completed the questionnaires.Statistical analysis was performed for the investigation results.Results The ayes age score of occupational stress for nurses in ICU was (3.41±0.73),which was in a moderate to high level.The main stress was that they regarded nursing as a high risk career,maximums working intensity,always overload work and frequent night-shift.While the average score of occupational stress for nurses in common wards was (3.29±1.05).The main stress was that they regarded nursing as a high risk career,Score of occupational stress between nurses in ICU and com wards had no statistical difference(P＞0.05).There was a significant negative correlation between occupational stress and social support for nurses in ICU(r=-0.159,P＜0.05).And the sup port by friends was into the equalion by multi-linear regression.Conclusions The level of occupational stress for murses in ICU was fairly hish.Scientific management of human resource,reducing work pressure of nurses and workloed,exerting various social support will benefit for reducing the stress of nurses in ICU.

Objective To explore the effect of multiple-formed nursing teaching ward-round.Methods Trainings and practices about muhiple-formed nursing teaching ward-round were executed to clinical instruction teachers.Results 95.9%of nursing students were satisfied with the quality of nursing teaching ward-round.After training ang practices,the evaluation to the nursing teaching ward-round and the scores of theoretic and operation examination of nursing students raised significantly(P＜0.05).Conclusions The trainings and practices improve the teachers' ability of utilizing multiple-formed nursing teaching ward-round,which not only enhance the students' study initiative,but also improve the query of nursing teaching teaching ward-round.

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.

Objective To investigate the risk factors of obstruction of central venous catheter(CVC)in the intensive care unit(ICU). Methods One hundred and thirty-three adult patients in ICU with CVC were included in the study. The difference of the position of catheters, duration of indwelling catheters,selection of sealing solution,blood platelet(PLT)count,prothrombin time(PT),international normalized ratio(INR),activated partial thromboplatin time(APTT),thrombin time(TT)and fibrinogen(FBG)were studied between two groups of patients(with and without the obstruction of CVC).Results In 117 cases,there were no catheter obstruction,accounting for 88.0%. Catheter obstruction occurred in 16 cases,accounting for 12.0%,10 cases of which the catheters were partially blocked,accounting for 7.5%and in 6 cases completely blocked,accounting for 4.5%.There were significant differences in the duration of indwelling catheters,PLT and FBG levels between the two groups of patients(all P<0.05).There was no significant difference in the position of catheters,selection of sealing solution and PT,INR,APTT,TT level between the groups(all P>0.05).Conclusion Prolonged time of indwelling CVC,high levels of PLT and clotting fibrinogen are the risk factors of the obstruction of CVC in ICU patients.

Objective To analyze the change of surgical route and range of hysterectomy in the past 10 years.Methods From January 2000 to December 2010,the clinical data of patients with hysterectomy were analyzed retrospectively,including clinical features,surgical path and scope of operation.Results There were 1980 patients.The predominant reason for hysterectomy was leiomyomas (52.88％,1047/1980),adenomyosis (17.78％,352/1980),cervical intraepithelial neoplasia (12.17％,241/1980).The age of the patients with hysterectomy for abdominal,transvaginal and laparoscopic was (46.54 ± 7.35),(58.73 ± 10.49),(44.10 ±5.12) years.In 2000-2005,the proportion of abdominal,transvaginal and laparoscopic proportion were 81.78％ (615/752),8.64％ (65/752) and 9.57％ (72/752).In 2006-2010 were 64.50％ (792/1228),6.51％ (80/1228) and 28.99％ (356/1228).In 2006-2010,the proportion of abdominal significantly decreased and laparoscopic significantly rised compared with those in 2000-2005,there were statistically significant differences (P ＜ 0.01).In 2000-2005,unilateral and bilateral annex removal ratios were 15.43％ (116/752),12.23％ (92/752),in 2006-2010 were 8.63％ (106/1228),7.49％(92/1228).Unilateral and bilateral annex removal ratios in 2006-2010 were significantly lower than those in 2000-2005,there were statistically significant differences (P ＜ 0.01 or ＜ 0.05).Conclusions Over the past 10 years,hysterectomy route and range changed with the percentage of laparoscopic increasing,and concomitant unilateral or bilateral annex removal decreased.

Objective To investigate the nutrition status and quality of life(QOL)in the perioperative patients with laryngeal cancer and to analyze the effect of nutrition status on quality of life.Methods Sixty-six patients with laryngeal cancer were surveyed respectively by self-designed general situation questionnaire,nutritional risk srcreening 2002(NRS2002)and European organization for research and treatment of cancer quality of life core questionnaire(EORTC QLQ-C30).The impact of nutritional status on QOL was analyzed by the multiple linear regression analysis.Results The total score of nutritional risk of perioperative patients with laryngeal cancer was 3.53±1.51 and the incidence of nutritional risk was 28.79%.The nutrition status influenced on QOL, physiological function,cognitive function and pain area(P<0.05).Conclusion Nurses should assess the nutritional status of the patients and correct malnutrition without delay in order to improve the physical function and QOL of the patients.

Objective To explore the role of problem-based learning(PBL) nursing ward round on critical thinking capacity of nurses from surgical departments. Methods All nurses from surgical depart-ments were randomly divided into the experimental group(86 nurses) and the control group(85 nurses) by drawing lots. Objects from the experimental group received PBL nursing ward round training twice a week for 8 months, while those from the control group used the traditional nursing ward round training. The influ-ence of the different teaching methods on the critical thinking capacity of the nurses was assessed before and after the training, using critical thinking disposition inventory-Chinese version (CTDI-CV). Results Total critical thinking capacity was improved significantly in the experimental group after the training. All sorts of critical thinking characteristics were strengthened in different degree. Conclusions PBL nursing ward round training can effectively facilitate the critical thinking capacity of surgical nurses.

Objective To apply Plato analysis method to clinical cases which were reported from clinical nursing, finding out the key link of the risks which were related to the cases:the key age, the key period, the key spectrum of disease and the key projects, etc. To carry out the feedforward control of the quality of care, and ensure the quality and safety of nursing. Methods A database were set up including clinical special cases, high-risk cases, security hidden danger cases and emergency cases. Thetwo eightprinciple of Plato analysis method was used to find out the main factors, the principal contradiction, the key hazard and the key problems of the cases, etc. The aim was to provide guidelines of risk analysis, risk prevention and risk aversion for nurses, and improve their consciousness of security hidden danger, and reduce security hidden danger cases. Results The results of 207 cases collected from 2014 to 2015 showed that the main risks involved the age groups were 41-80 years old and 21-30 years old. The major risks involved the spectrum of disease were the nervous system, cardiovascular disease, surgical anesthesia related problems, kidney disease, cancer and respiratory system. The major risks involved the time were the midnight, morning and afternoon. The major risks involved the locations were sickroom, emergency room, auxiliary inspection departments and outpatient. The major risks involved items were disease mutation, psychological problems, medication safety and instrument safety, among the disease mutation, timely discovered, rescued 13 patients with heart and breathing pause, stop 13 patients who attempted suicide. Since the Plato analysis method was applied to identify the security risks of the clinical cases, the number of falling, all kinds of pipe shed, skin problems and suicides were decreased from 6, 6, 7, 5 in 2014 to 2, 2, 2, 1 in 2015, declining trend year by year. Conclusions Applying the Plato analysis method to identify the security risks of the clinical cases which can find out the main problems of cases and improve nursing quality and management efficiency.

Objective To investigate the role of transient receptor potential vanilloid tpye 1 (TRPV1) in the pathological process of detrusor overactivity (DO) induced by partial bladder outlet obstruction (BOO).Methods Between June 2014 and December 2014,40 female Wistar rats received partial urethral ligation and urodynamic analysis 6 weeks after.Urinary bladder and dorsal root ganglion (DRG) were removed and RT-PCR,Western Blot and IHC were performed to investigate the expression and location of TRPV1 in control and DO rats.Effect of different concentrations of TRPV1 agonist,as well as TRPV1 antagonist,was also evaluated with isolated detrusor strips.Results 40 female Wistar rats received BOO surgery and 26 of them developed DO.Immunohistochemistry observed linear TRPV1-reactive staining mainly in sub-urothelial and muscular layer.Expression of TRPV1 mRNA and protein in urinary bladder [(0.18±0.02) vs.(0.36 ±0.03),P＜0.05] and dorsal root ganglia (DRG) [(0.41 ±0.05) vs.(0.66 ±0.04),P ＜ 0.05] significantly increased in BOO induced OAB rats.In isolated detrusor strips studies,the amplitude [(0.26 ±0.05)g vs.(0.69 ±0.11)g,P ＜0.05] and frequency [(5.91 ±0.59) Hz vs.(8.75 ± 0.54) Hz,P ＜ 0.05] of contractions of DO tissues were significantly higher than that of control ones.Capsaicin significantly increased the amplitude but not frequency of detrusor intrinsic contractility and this effect was enhanced in OAB conditions.All changes induced by capsaicin were blocked by capsazepine pre-incubated.Conclusions In BOO induced DO rats,over-expressed TRPV1 was involved in DO pathological process by directly sensitizing bladder afferent fibers or indirectly enhancing detrusor intrinsic properties.
