ObjectiveTo investigate the current awareness and optimization recommendations on pneumonia with unknown etiology (PUE) surveillance among Shanghai healthcare professionals, and to provide evidence for the improvement of the surveillance system. MethodsIn December 2024, healthcare professional participants from diverse medical and health institutions were randomly selected within each stratum using a stratified cluster sampling method in all 16 districts of Shanghai for questionnaire surveys on their knowledge and suggestions for optimization of the PUE surveillance system. Descriptive statistics analyses, multivariate logistic regressions, and content analyses were used for data analyses. ResultsA total of 385 survey subjects were involved in the study, including 119 professional staffs from disease prevention and control centers and 266 from medical institutions. Those who understood the case definition for PUE correctly accounted for 67.01% (258/385). Multivariate regression model analyses showed that female gender (aOR=2.22, 95%CI: 1.36‒3.66), professionals from disease control institutions (aOR=2.02, 95%CI: 1.12‒3.72), and those who self-assessed as being familiar with the monitoring system (aOR=2.18, 95%CI:1.23‒3.89) had better understanding of the definition. Overall, 89.61% (345/385) of the survey subjects acknowledged the necessity of the surveillance system. Small number of cases meeting the case definition (54.46%, 214/379), insufficient diagnostic awareness (39.84%, 151/379), and lack of incentives for case reporting (29.29%, 111/379) were major problems for the current surveillance system, with variations observed across different types of institutions. Suggested segments for optimizing the surveillance system included monitoring purpose, case definition, form of monitoring and reporting procedure, organization mechanism, and epidemiological investigation and response. ConclusionThe necessity of PUE surveillance is commonly recognized among healthcare workers. However, the existing system falls short in terms of mastery of case definition and overall surveillance adaptability. There is an urgent need for optimization and improvement to enhance the capacity for preventing and controlling emerging and sudden respiratory infectious diseases.

Pyroptosis is a kind of programmed cell death accompanied by inflammatory responses, which is mainly induced by the Caspase-1/4/5/11 activated mediated via inflammasomes or lipopolysaccharide.Pyroptosis causes the cleavage of various Gasdermin family members, including Gasdermin D, in which a large number of pro-inflammatory factors are released to cause inflammatory responses in various diseases.At present, pyroptosis has not been extensively analyzed in pediatric surgical diseases.This review summarizes the research progress of pyroptosis in pediatric surgical diseases like Hirschsprung′s disease, biliary atresia, neonatal necrotizing enterocolitis, and tumors.It is found that pyroptosis is involved in the occurrence and development of pediatric surgical diseases.The research on the specific mechanism of pyroptosis in pediatric surgical disease and involved signaling pathways contributes to the early diagnosis and treatment of some pediatric surgical diseases.

Objective:To explore the application effect of situation comedy teaching combined with peer teaching in clinical practice teaching of undergraduate nursing students.Methods:A total of 96 undergraduate nursing students who practiced in a first-class hospital at grade 3 in 2019 were randomly divided into the observation group and the control group, with 48 nursing students in each group. The control group adopted clinical teaching mode, including group theory teaching and group operation demonstration. On the basis of this, the observation group additionally adopted the clinical teaching mode of situation comedy teaching combined with peer teaching. The differences between the two groups in the assessment of nursing knowledge and skills assessment, independent learning ability and teaching satisfaction were observed. SPSS 20.0 software was used for t-test. Results:After the implementation of clinical teaching, the scores of nursing comprehensive ability of nursing students in the observation group (87.71 ± 5.11) were higher than those in the control group (78.47±6.24) ( P < 0.05). The independent learning ability of nursing students in the observation group (98.80±10.61) was significantly higher than that in the control group (74.47±9.83), and the difference was statistically significant ( P < 0.05). The score of teaching satisfaction in the observation group (2.83±7.07) was significantly higher than that in the control group (50.17±6.75), and the difference was statistically significant ( P < 0.05). Conclusion:The application of situation domedy teaching combined with peer teaching in the clinical teaching of undergraduate nursing students can improve their independent learning ability and clinical practice ability. Meanwhile, the process of teachers and students participating in situational experience and peer analysis and discussion can increase the teacher-student interaction, and improve the satisfaction of nursing students with clinical teaching.

Purpose: The aim of the study was to evaluate the status of psychological resilience among women in their second pregnancy and to investigate the possible influencing factors. Methods: A total of 275 women in their second pregnancy and who met the criteria were surveyed from two public hospitals in China from July 2018 to January 2019. The instruments included the General Self-designed Questionnaire, Connor–Davidson Resilience Scale, Social Support Rate Scale, and 36-item Pregnancy Stress Rating Scale. Results: The total psychological resilience score of second-pregnancy women was relatively low. Multivariate regression analysis identified five factors associated with psychological resilience: intimacy with husbands, social support utilization, gender of the first child, high-risk pregnancy of the first child, and the stress caused by worrying about the health and safety of the mother and fetus. Conclusion Women in their second pregnancy represent a unique population, and their low psychological resilience score deserves attention. Identification of factors contributing to decreased psychological resilience may enable us to design prevention and intervention strategies and to deliver specific psychological supports to pregnant women at high risk of developing negative psychology.

Objective:To analyze the epidemiological characteristics of a cluster of 5 confirmed COVID-19 cases related with the transmission in incubation period of initial case, and find out the infection source and transmission chain.Methods:According to "The Prevention and Control Protocol for Coronavirus Disease 2019 (Third Edition)" issued by the National Health Commission, a field epidemiological survey was conducted for the 5 cases in January 2020. Nasopharyngeal swabs and sputum samples were collected from them for the detection of 2019-nCoV by real time RT-PCR. Multi prevention and control measures were taken, such as tracking and screening close contacts, medical isolation observation, investigating the epidemiological link, analyzing transmission chain.Results:Case 1, who had common environmental exposure with other COVID-19 cases, got sick on 20 January, 2020 and was confirmed on 1 February. Case 2 became symptomatic on 22 January and was confirmed on 27 January. Case 3 got sick on 25 January and was confirmed on 30 January. Case 4 had illness onset on 20 January and was confirmed on 1 February. Case 5 got sick on 23 January and was confirmed on 31 January. Among the 5 cases, case 2 died and the illness of other cases were effectively controlled. After exclusion of other common exposure factors, case 1 had a 6-hour meeting with case 2 and case 3 on 19 January. Case 2 and case 3 might be infected by case 1 during the incubation period. It is the key point for epidemiological investigation.Conclusion:The epidemiological investigation indicates that the transmission might occur in the incubation period of COVID-19 case, close attention should be paid to it in future COVID-19 prevention and control.

Objective:To analyze the epidemiological characteristics of imported COVID-19 cases in early phase in Shanghai, introduce measures and provide reference for prevention and control of imported COVID-19 cases.Methods:Data of imported COVID-19 cases in Shanghai reported as of 30 March, 2020 were obtained from National Notifiable Disease Report System of China CDC and field epidemiological investigation reports by CDCs in Shanghai. The information about measures of prevention and control was collected from official websites and platforms of the governments. Data cleaning and statistical analysis were performed with softwares of EpiData 3.1, Excel 2019 and SAS 9.4.Results:A total of 171 imported COVID-19 cases had been reported as of 30 March, 2020 in Shanghai, including 170 confirmed cases and 1 asymptomatic infection case. Among them, cases of Chinese nationality accounted for 71.3% (122/171) and cases of foreign nationality accounted for 28.7% (49/171). The median age of the cases was 23 years ( P 25, P 75: 18, 35 years), and the male to female ratio of the cases was 1.3∶1. Students accounted for 56.6% (97/171). About 45.6% (78/171) of the cases fell ill before arriving in Shanghai. The cases with mild or common clinical manifestation accounted for 96.5% (165/171) and no significant difference in clinical type was observed between overseas Chinese cases and foreign cases. The epidemic curve by diagnosis date reached peak on March 24, and the number of the cases gradually declined due to the closed-loop management process of joint port prevention and control mechanism. The 171 imported COVID-19 cases were mainly from 24 countries and regions, including the United Kingdom (64 cases, 37.3%), the United States (32 cases, 18.6%), France (19 cases, 11.0%) and Italy (16 cases, 9.4%). About 40.4% of the cases (69/171) planned to continue travelling to 21 other provinces and municipalities in China. Customs quarantine and community observation/detection points identified 43.9% (75/171) cases and 31.0% (53/171) cases, respectively. Conclusions:The imported COVID-19 cases in early phase in Shanghai were mainly young population and students accounted for high proportion. The imported risk of COVID-19 was consistent with the severity of the epidemic in foreign countries. The closed-loop management model of the joint port prevention and control mechanism plays an important role in the identification and management of the imported COVID-19 cases.

Objective To analyze the situation of the hospital humanistic caring in our country and provide a reference for the later humanistic nursing practice and research.Methods Relevant literature were searched in Chinese Biomedical Database,Wanfang Database,China National Knowledge Infrastructure from their establishment to June 2016 and analyzed with bibliometric methods.Results A total of 181 studies were included.The data analysis showed an increasing trend since 2004.Humanistic nursing was more applied to the vast general hospitals in the eastern coastal region of China(60%,108/181).Besides,the humanistic nursing researches were mainly in single department.Of the total,random control trial accounted for the most substantial proportion(61%,111/181).40%of the researchers considered the human environment,psychological care and communication as the most crucial humanistic nursing measures.Assessment index including satisfaction,psychology was mostly used to evaluate the effect of these measures.Conclusions Humanistic nursing is practiced widely.However,there are still some problems in the research methods.There are no standards of practice and evaluation,so these need to be further explored.

Objective This study evaluated the effects of health education promoting therapeutic lifestyle changes in a population with dyslipidemia. Methods Patients with dyslipidemia were randomly assigned to one of four groups: the current group (CG) received conventional health guidance, the educational course (EC) group attended six lectures as part of an educational course, the phone call (PC) group received twice-monthly follow-up by telephone,and the comprehensive group(EC+PC)attended both the educational course and received follow-up telephone calls. Total cholesterol (TC), total triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein (HDL-C), and the knowledge, attitude, and behavior (KAP) score for blood lipids were compared within each group and among groups. Results A total of 214 patients were enrolled and completed the study: 62 patients in CG,49 patients in EC,56 patients in PC,and 47 patients in EC+PC.There were significant differences in the EC,PC,and EC+PC groups after the 24-week intervention. For example, pre- and post-intervention values for each group were as follows:EC group:(5.74±0.69)mmol/L and(5.14±0.87)mmol/L for TC,35.22±1.67 and 42.96±5.72 for KAP;PC group:(5.63±0.58)mmol/L and(5.22±1.07)mmol/L for TC, 34.54.±0.97and 39.41±5.03 for KAP;EC+PC group:(5.60±0.48)mmol/L and(4.00±0.79)mmol/L for TC,35.44±1.80 and 45.05±3.19 for KAP, respectively (P<0.05). The CG group showed no significant differences before and after treatment:(5.66±0.54)vs.(5.32±1.28)mmol/L for TC,34.37±0.65 vs.35.28±4.02 for KAP(P>0.05).In a comparison among the four groups,the EC and PC groups showed greater improvements than the CG group.Moreover, the EC+PC group showed statistically significant differences in the results compared with the other three groups (P< 0.05). Conclusion An educational course combined with telephone follow-up calls was more effective than a single intervention in improving blood lipids and enhancing the health awareness of patients with dyslipidemia.This combined health education model not only improves the effectiveness of treatment to some degree,but also plays a role in its supervision and management.Furthermore,it may also assist in the implementation of continuous nursing services in medical institutions.

BACKGROUND:Numerous studies have shown that mesenchymal stem cel s (MSCs) can effectively attenuate the fibrosis of damaged heart, lung and kidney by secreting various bioactive factors. OBJECTIVE:To evaluate the anti-fibrotic therapeutic potential of bone marrow MSCs conditioned media in vitro. METHODS:Normal fibroblasts and hypertrophic scar fibroblasts were treated with bone marrow MSCs conditioned media, then transforming growth factor-βand col agen production were analyzed by ELISA, and mRNA expression level of Smad7 and hydroxyproline content were detected by RT-PCR and colorimetry, respectively. RESULTS AND CONCLUSION:Bone marrow MSCs conditioned media significantly inhibited the production of both transforming growth factor-βand col agen in hypertrophic scar fibroblasts (P<0. 01), and up-regulated the mRNA expression level of Smad7 (P<0. 01), a major inhibitory regulator in the SMAD family. However, the normal fibroblasts were scarcely influenced by bone marrow MSCs conditioned media. These findings indicate that bone marrow MSCs conditioned media is considered a promising candidate for the treatment of hypertrophic scars, which may provide new theoretical supports to reduce cutaneous scarring.
