Background The mental health problems of employees in administrative organs and public institutions are highly valued.However,there is a lack of understanding regarding the mental health status of employees in provincial and municipal administrative organs and public institutions in Qinghai region.Objective To analyze the anxiety and depression of employees in provincial and municipal administrative organs and public institutions in Qinghai region,so as to provide references for promoting their mental health and intervening in psychological problems.Methods From October 23 to 28,2022,a total of 3 096 employees in provincial and municipal administrative organs and public institutions in Qinghai region were enrolled using stratified cluster sampling technique,and were assessed using Self-rating Anxiety Scale(SAS)and Self-rating Depression Scale(SDS).Results A total of 1797(58.04％)employees in municipal and above administrative organs and public institutions in Qinghai region completed a valid questionnaire survey.Depressive symptoms were noted in 579(32.22％).SDS scores yielded statistical difference among the selected employees of different ethnicities,types of job positions and educational levels(F=9.074,101.488,4.477,P<0.01),and the severity of depressive symptoms also demonstrated statistical difference among the selected employees with different ethnicities,educational levels and types of job positions(H=49.196,17.028,160.848,P<0.01).Anxiety symptoms were detected in 711(39.57％)employees.SAS scores exhibited statistical difference among the employees with different genders,ages,ethnicities,educational levels,marital status and types of job positions(t=-4.571,F=6.648,3.950,5.243,12.008,22.253,P<0.01).Statistical differences were also illustrated in the severity of anxiety symptoms among the selected employees with different ages,genders,ethnicities,educational levels,marital status and types of job positions(H=24.361,-3.788,28.365,24.268,25.976,56.204,P<0.01).Conclusion About one-third of employees in municipal and above administrative organs and public institutions in Qinghai region may have symptoms of depression and anxiety.The depression symptoms are more severe among Tibetan people,those with low education levels and ordinary civil servants.The anxiety symptoms are more severe among employees aged 30 and below,those with low education levels,unmarried and those in technical positions.

Objective To investigate the correlation and consistency between the parameters of thromboelastography(TEG)and routine coagulation tests,and to evaluate the application value of the two methods in heparin anticoagulation monitoring and coagulation function monitoring in patients receiving extracorporeal membrane oxygenation(ECMO)therapy.Methods A total of 138 patients who recieved ECMO in the Department of Critical Care Medicine of the People's Hospital of Guangxi Zhuang Autonomous Region from October 2021 to December 2022 were selected.A total of 317 pairs of ordinary TEG and heparinase-modified TEG(hmTEG)parameters measured simultaneously were analyzed for correlation and consis-tency with activated partial thromboplastin time(APTT),fibrinogen(Fib),and platelet count(Plt),and the parameters tested when ECMO was established and 24 hours after ECMO operation were compared.Results The correlation coefficient between R values and APTT of hmTEG(r=0.441,P<0.05)was lower than that of ordinary TEG(r=0.547,P<0.05).The parameters α-Angle and K value of ordinary TEG were not correlated with Fib(P>0.05),while as for hmTEG,the correla-tion was 0.359(P<0.05)and-0.343(P<0.05),respectively.The correlation between MA value of hmTEG and Plt was 0.456(P<0.05),which was much lower than its correlation with Fib(r=0.715,P<0.05).APTT and hmTEG had moderate agreement in judging the anticoagulant effect of UFH(P<0.05).Plt at 24 hours after ECMO was significantly lower than that at establishment of ECMO(P<0.05).Fib,APTT and hmTEG parameters were not significantly different between the two groups(P>0.05).Conclusion The parameters of hmTEG can better reflect the real level of coagulation factors in patients receiving ECMO.The results of hmTEG and APTT are complementary to assess whether heparin in ECMO patients is over-dosed,and hmTEG has unique advantages.Routine coagulation tests and TEG cannot replace each other,and the combina-tion of them can achieve better anticoagulation and coagulation management.

Objective This study aims to investigate the selection intention of nursing interns and their influencing fac-tors,providing a scientific basis for nursing human resource management in hospitals and departments.Methods A convenience sampling method was used to conduct a questionnaire survey A questionnaire survey was conducted concerning the selection inten-tion on departments and influencing factors of intern nurses from several tertiary hospitals affiliated to three medical universities from July 2022 to December 2023.General data investigation and self-developed scales were employed,and descriptive analysis,chi-square test and other statistical methods were used to analyze the differences in department selection and related influencing factors among nursing interns.Results Analysis of 652 valid questionnaires revealed that surgery(65.80％)and operating room(38.84％)were the most preferred departments for nursing interns.The primary influencing factors included the working environment and equipment of the department(54.60％),as well as its cohesion and cultural atmosphere(51.53％).Pediat-rics(51.23％)and infectious medicine(48.77％)were found to be less favored by nursing interns.Their main concerns re-volved around work-related risks and population characteristics of patients(67.02％),along with work pressure and labor intensi-ty(65.49％).Epidemic factors have an impact on the attitudes and expectations of nursing interns towards their future practice(P＜0.01).Conclusion The choice of departments by nursing interns is influenced by various environmental,societal and personal factors;primarily based on departmental environment quality and team culture atmosphere considerations.During the in-ternship,nursing interns require more professional education guidance from both hospital administration and individual depart-ments in order to make informed career choices and plans.

OBJECTIVES: To investigate vitamin D nutritional status in children after outbreak of coronavirus disease 2019 (COVID-19), as well as the effect of strict epidemic prevention and control measures for the COVID-19 epidemic on vitamin D nutritional status in children. METHODS: A total of 7 460 children who underwent routine physical examinations from February to August, 2020 and had normal results were retrospectively enrolled as the observation group, and 10 102 children who underwent routine physical examinations from February to August, 2019 (no epidemic of COVID-19) and had normal results were enrolled as the control group. The serum level of 25-hydroxy vitamin D [25(OH)D] was compared between the two groups. The children in the observation and control groups who underwent physical examinations in March and April were selected as the epidemic prevention subgroup ( RESULTS: The observation group had a lower serum level of 25(OH)D than the control group in March and April ( CONCLUSIONS Strict prevention and control measures for the COVID-19 epidemic may lead to a significant reduction in vitamin D level in children, especially school-aged and adolescent children. It is recommended to timely monitor vitamin D level in children, take vitamin D supplements, and increase the time of outdoor sunshine as far as possible under the premise of adherence to epidemic prevention regulations.

Objective:To evaluate the recurrence patterns of esophageal squamous cell carcinoma (ESCC) after radical surgery and analyze the predictors of post-recurrence survival (PRS).Methods:A total of 382 ESCC patients who developed recurrence after radical surgery were retrospectively reviewed from January 2007 to December 2011. All of them received salvage treatment after recurrence. The Univariate analysis was determined using the Kaplan-Meier method and log-rank test. Multivariate prognostic analysis was determined using the Cox proportional hazard model.Results:The 1-, 3-, 5-year overall survival (OS) rates were 80.9%, 35.6% and 20.4%, respectively. The median survival time and recurrence time were 29.2 months and 15.0 months. The 1-, 3-, 5-year PRS rates were 37.7%, 14.6% and 11.9%, respectively. The median PRS time was 10.2 months. Locoregional recurrence was noted at 462 sites among 382 patients including 20.5% (95/462) of sites in supraclavicular LN (lymph node), 10.0% (46/462) in anastomosis, 56.1% (259/462) in mediastinal regional LN and 13.4% (62/462) in upper abdominal LN. There were 156, 43, 82 and 101 patients treated with salvage radiotherapy, chemotherapy, chemoradiotherapy and palliative care after recurrence, respectively. The univariate analysis showed that T stage, N stage, TNM stage, recurrence site, number of recurrent regions and treatment regimen after recurrence were significantly correlated with PRS ( χ2=5.336, 4.292, 8.067, 7.482, 4.093, 76.426, P<0.05). Patients receiving salvage radiotherapy with the median dose of 60 Gy, were divided into <60 Gy group and ≥ 60 Gy group. The ≥60 Gy group had a better PRS than <60 Gy group ( χ2=8.320, P<0.05). Multivariate analysis showed that number of recurrent regions and treatment regimen were independent prognostic factors of PRS. Conclusions:Mediastinal and supraclavicular regions were the most common sites of recurrence in ESCC patients after radical surgery. Salvage radiotherapy and chemoradiotherapy could significantly improve PRS in recurrent ESCC patients.

Objective: To study the relationship between the dose-volume indexes and acute toxicity of intrathoracic stomach in esophageal cancer patients receiving radiotherapy after esophagectomy. Methods: A total of 104 patients treated with postoperative radiotherapy followed by radical esophagectomy were enrolled. The dose-volume indexes of intrathoracic stomach were collected from treatment planning system. The ROC curve and logistic regression were performed to analyze the relationship between acute toxicity of intrathoracic stomach and clinical parameters, dose-volume indexes. Results: A total of 29 patients (27.88 %) suffered from grade 2 or above acute toxicity. The ROC curve analysis showed that the dose-volume indexes including D_max, D_mean, L₅-L₄₅ and V₅-V₅₀were associated with occurrence of grade 2 or above acute toxicity. The univariate analysis showed that location, D_max, D_mean, L₅-L₄₅ and V₅-V₅₀ were significantly correlated with the incidence of grade 2 or above acute toxicity (P<0.05). The multivariate analysis showed that location, L₅ and V₃₅ were independent factors for incidence of grade 2 or above acute toxicity. The ROC curve analysis showed that cut-off values of L₅ and V₃₅ were 14.00 cm and 44.00%, respectively. And the rates of Grade 2 or above acute toxicity were 20.00% for L₅>14.00 cm and 38.64% for L₅≥14.00 cm (χ²=4.473, P<0.05), 14.08% for V₃₅<44.00% and 57.58% for V₃₅≥44.00% (χ²=7.263, P<0.05), respectively. The incidence of grade 2 or above acute toxicity was significantly higher in post-mediastinum stomach group than the other two groups (χ²=12.881, P<0.05). Conclusions Dose-volume index may be indicator to predict acute toxicity of intrathoracic stomach. It is recommended that post-mediastinum stomach should be chosen carefully if esophageal cancer patients require postoperative radiotherapy.

Objective To determine the value of using B-type natriuretic peptide (BNP) and D-dimer in preliminary recognition of cardioembolic stroke patients.Methods A mutilple-center study was conducted in Foshan Hospital of traditional Chinese Medicine (TCM) and its affiliated hospitals from July 2015 to July 2016.In the emergency departments (EDs),emergency physicians prospectively assessed consecutive adult patients with acute cardioembolic stroke and measured plasma BNP by POCT platform on admission,then followed up.Stroke neurologists evaluated patients' functional outcome at hospital discharge and also made discharge diagnosis and stroke etiologic subtypes according to the TOAST criteria.Results In this study,290 acute ischemic stroke patients met the study criteria [mean age (68.41 ± 12.06) years;53.8％ female].Of the enrolled patients,28.3％ were diagnosed with LAA at discharge,17.9％ with CE,42.8％ with SAO,11.0％ with SOE or SUE.And the mean BNP concentration was significantly higher in the CE group than that in other three subtypes (P ＜ 0.001).After adjustment for multiple clinical predictors like gender,age,coronary artery disease,atrial fibrillation and renal function,BNP and D-dimer were associated with CE [BNP OR:1.044 (95％ CI 1.025,1.064),P ＜ 0.001;D-dimer OR:1.511(95％ CI 1.020,2.238),P =0.039,respectively].Conclusion Through POCT technique in the EDs,cardioembolic stroke patients can be differentiated from other TOAST subtypes.BNP with/without D-dimer has good but different corresponding diagnostic performance in preliminary recognition of cardioembolic stroke patients.
