Objective To investigate the factors influencing mood and sleep among special operation personnel,so as to provide evidence for the prevention and intervention of related issues.Methods A total of 600 special operation personnel during their special duty were enrolled by random sampling method.Basic information was collected by a general information questionnaire.Mood and sleep status were evaluated by self-rating anxiety scale(SAS),self-rating depression scale(SDS),and Pittsburgh sleep quality index scale(PSQI).Results Spearman correlation analysis showed that factors associated with anxiety were years of work experience(r=0.099,P=0.016),family residence(r=-0.153,P＜0.001),and sleep status(r=0.199,P＜0.001);the factors associated with depression were relationship with parents(r=-0.134,P=0.001),family residence(r=-0.144,P＜0.001),and sleep status(r=0.122,P=0.003);and the factors associated with sleep were age(r=0.088,P=0.031),years of work experience(r=0.079,P=0.049),and number of children(r=0.083,P=0.043).Binary logistic regression analysis showed that depression was not an influencing factor of sleep(odds ratio[OR]=1.302,95%confidence interval[95%CI]0.759-1.758,P=0.086),while anxiety was an influencing factor of sleep(OR=2.187,95%CI 1.608-4.695,P=0.001).Conclusion The sleep status of special operation personnel investigated in this survey is related to age and years of work experience,and is influenced by anxiety.Therefore,greater attention should be given to sleep issues in the occupational health support of special operations.Additionally,years of work experience,family residence,relationship with parents,and sleep status are related to anxiety and depression among special operation personnel.It is necessary to focus on the mental health of older workers and those with longer tenure.

Objective To investigate the value of minimum apparent diffusion coefficient(ADCmin)and delta apparent diffusion coefficient(dADC)of quantitative parameters of MR diffusion weighted imaging(DWI)in differentiating benign from stage Ⅰ malignant ovarian epithelial tumors.Methods A total of 112 patients with primary ovarian epithelial tumors confirmed by operation and pathology(43 benign tumors and 69 stage Ⅰ malignant tumors)were retrospectively selected.All patients underwent routine MRI and DWI before operation.The ADCmin and dADC of solid portion were measured and compared between the two groups.Logistic regression anal-ysis and receiver operating characteristic(ROC)curve were used to evaluate diagnostic performance of each parameter alone and in combination in differentiating ovarian epithelial benign and stage Ⅰ malignant tumors.Results The ADCmin was greater in benign tumors than that in stage Ⅰ malignant tumors,while dADC was smaller in benign tumors than that in stage Ⅰ malignant tumors(P＜0.05).Logis-tic regression analysis showed that ADCmin and dADC were independent risk factors for stage Ⅰ malignant tumors.With threshold of 1.183 × 10-3 mm2/s for ADCmin and 0.579 × 10-3 mm2/s for dADC,the area under the curve(AUC)was 0.802 and 0.857,sensitivity and specificity of 0.885,0.808,0.714,0.857,respectively.According to regression equation logit(P)=7.154+0.267 × dADC-1.016 X ADCmin,the AUC(0.951)was greater than that of single parameter,the sensitivity was 0.890,the specificity was 0.995.Conclusion ADCmin and dADC are useful for differentiating ovarian epithelial benign from stage Ⅰ malignant tumors,and ADCmin combined with dADC can improve the diagnose accuracy before operation.

Nursing human resource is an important part of health human resource and the basis of ensuring nursing quali-ty.Effective nursing performance management can mobilize nurses'subjective initiative,improve work efficiency and enhance nursing human resource management level.At present,the exploration of nursing performance management in public hospitals in China is in the initial stage,and the management mode still refers to the enterprise human resource management mode,without fully considering the particularity of medical work,leading to many problems in the current nursing performance salary manage-ment.Through questionnaire survey,this paper understands the current situation of nursing human resources and performance man-agement methods of comprehensive public hospitals in different regions of the country,analyzes the problems existing in nursing per-formance management and their causes,and puts forward reasonable suggestions for reform direction.In order to provide reference for the reform of nursing performance management in public hospitals,make the distribution of nursing performance much fair and reasonable,improve the quality of nursing service,and promote the sustainable development of nursing management.

Objective To investigate the current status and influencing factors of mental disorders in working women in psychological clinic of a first-class hospital in Shanghai,so as to provide guidance for prevention and treatment of this disease.Methods A cross-sectional survey was conducted on 122 working female patients from the psychological clinic of a first-class hospital in Shanghai.Mental health status was assessed by General Situation Scale,Self-Efficacy Scale,Patient Health Questionnaire-9(PHQ-9),Generalized Anxiety Disorder-7(GAD-7),Yale-Brown Obsessive-Compulsive Scale(Y-BOCS),Hypomania Checklist-32(HCL-32),Patient Health Questionnaire-15(PHQ-15),AIS scale,and individual interviews.Descriptive statistics,non-parametric test,and multivariate logistic regression analysis were used to investigate the influencing factors of mental disorders in working women.Results The scores of anxiety,depression,compulsion,bipolar disorder,somatization symptoms,and insomnia were 12.02±4.29,14.91±5.53,6.09±5.71,7.28±5.25,13.54±6.29,and 10.79±5.27,respectively.Mild anxiety(36.1%),moderate depression(36.1%),and severe somatization(39.4%)were very common in these patients.Additionally,compulsive behaviors were found in 18.0%of the patients,bipolar disorder in 22.1%,and insomnia in 68.0%.Five factors(such as work hours)were related to anxiety(all P<0.05).Six factors(such as education level)were related to depression(all P<0.05).Seven factors(such as workplace relationships)were related to compulsions(all P<0.05).Age and four other factors were related to bipolar disorders(all P<0.05).Career development and three other factors were related to somatization(all P<0.05).Insomnia was significantly influenced by overtime work and five other factors(all P<0.05).Multivariate logistic regression analysis indicated that bad job stability and two other factors were risk factors for anxiety(all P<0.05),low self-efficacy and two other factors were risk factors for depression(all P<0.05),bad workplace relationships and two other factors increased compulsive behaviors(all P<0.05),more housing expenses increased bipolar disorders(P<0.05),more overtime aggravated somatization(P<0.05),and long working hours and two other factors worsened insomnia(all P<0.05).Conclusion Mental disorders in working women have become a common social issue,and are mainly influenced by individual factors(age,marital status,education level,housing expenses,and self-efficacy)and work-related factors(industry type,work hours,overtime,workplace relationships,job stability,career development,and corporate focus on female employees).Effective interventions from personal,corporate,and social perspectives are the key to preventing and treating mental disorders in working women.

Objective To discuss the value of Fisher discriminant analysis of serum progesterone and the growing rate of β-human chorionic gonadotropin in the prediction of early ectopic pregnancy. Methods 66 patients with ectopic pregnancy (11 cases were successfully treated expectantly and 55 cases were treated surgically including 40 cases of rupture of fallopian tube and 15 cases of tubal abortion) and 55 patients with intrauterine pregnancy and 50 patients with threatened abortion were chosen. Serum progesterone,β-HCG,48 hβ-HCG and the 48 h growing rate of β-HCG in each group were measured and a Fisher discriminant analysis was used. Results The serum progester-one was (30.27± 18.20) nmol/L in ectopic pregnancy group,( 108.44±23.27 ) nmol/L in intrauterine pregnancy group and (91.68±34.90) nmol/L in threatened abortion group. The first β-HCG was ( 3767.63 ± 3530.38 ) U/L in ectopie pregnancy group,(29 028.65 ± 10 874.01 )U/L in intrauterine pregnancy group and (13 457.47±16 367.65)U/L in threatened abortion group. The second β-HCG was (4349.24±3536.22)U/L in ectopic pregnancygroup,(56 139.46 ± 23 296.87 ) U/L in intrauterine pregnancy group and (23 270.63 ± 23 811.68 ) U/L in threat-ened abortion group. The growing rate of β-HCG ( β-HCG/the first serum β-HCG) was 1.29 ± 0.28 in ectopic preg-nancy group,1.93 ± 0.36 in intrauterine pregnancy group and 1.97±0.28 in threatened abortion group. There was significant difference in serum progesterone,the first β-HCG and the second β-HCG as well as the growing rate of β-HCG among the groups(P<0.05 or <0.01). Fisher discriminant analysis of combing progesterone and the growing rate of β-HCG were connected with diagnosis of ectopic pregnancy,however,the only one serum β-HCG was not con-nected with diagnosis of ectopic pregnancy. 98.5% of ectopic pregnancy,65.6% of intrauterine pregnancy and 64.0% of threatened abortion were correctly classified in the Fisher discfiminant analysis,with overall correct rate of 77.8%. Conclusion Fisher discriminant analysis of combing progesterone and the growing rate of β-HCG can bet-ter predict the early ectopic pregnancy.
