The Department of Thoracic Surgery of Shanghai Chest Hospital has performed esophageal function testing for over 30 years, being the only department of its kind in China with this capability. The pressure testing and 24-hour pH/impedance monitoring of the esophagus is of great help to assist in the diagnosis and treatment of benign and malignant esophageal diseases related to it. Thanks to the esophageal function test, in addition to the routine various endoscopic anti-reflux procedures, our hospital has taken the lead in China in recent years to carry out a series of clinical and research work for benign esophageal diseases, such as the development of magnetic ring, double nedoscopic combination and new anti-reflux endoscopic techniques. In recent years, we have carried out high-resolution esophageal manometry and 24-hour pH/impedance monitoring for patients with interstitial pneumonia and pulmonary fibrosis suspected to be caused by gastroesophageal acid reflux. We can better assess the correlation between gastroesophageal reflux and pulmonary fibrosis, and to provide the different clinical treatments and even surgical interventions. The Bravo capsule is used more often in the United States, and it has obvious advantages over traditional approach for acid measurement. We strongly call for the collaboration between industry and academic institutions in this field, and the development of our own related products with independent intellectual property rights.

Objective To investigate the predictive value of urinary exosomal microRNA(miR)-29 c in the clinical outcome of organ-and non-organ-confined bladder urothelial carcinoma(BUC).Methods From January 2017 to March 2022,152 patients with BUC were recruited from the Department of Urology in our hospital as a validation set.In addition,126 non-cancer controls were selected from the physical examination center of our hospital.The expression level of urinary exosomal miR-29c was detected by real-time quantitative PCR.Results In the validation set,urinary exosomal miR-29c level in BUC patients was significantly lower than that in non-cancer control group(P＜0.05),while urinary exosomal miR-17-5p level and miR-590-5p level were not significantly different(P＞0.05).The area under ROC curve of urinary exosomal miR-29c for the diagnosis of BUC was 0.969(95％CI:0.953～0.986),and the corresponding sensitivity and specificity were 92.1％and 90.2％,respectively.In subtype analysis,urinary exosomal miR-29c levels were further reduced in patients with non-organ-confined BUC compared with patients with organ-confined BUC(P=0.009).Overall survival(OS),disease-free survival(DFS)and disease-specific survival(DSS)were longer in the urinary exosomal miR-29c high expression group(P＜0.05).Conclusion Low levels of urinary exosomal miR-29c are an adverse prognostic factor for survival in patients with BUC,and are promising as a predictor of adverse clinical outcomes of organ-and non-organ-confined BUC.

Objective:To investigate the status of self-management and family support among elderly diabetic patients in community.Methods:Eight elderly patients with type 2 diabetes were interviewed in Xietu Community Health Service Center in Shanghai by semi-structured interviews from March 1st to March 15th, 2022. The interview outline focused on the impact of the disease on the patients' daily life, the status of disease self-management, and the support provided by their family. The contents of interviews were analyzed and extracted by Colaizz 7-step analysis method.Results:Of the 8 interviewees, there were 2 males and 6 females, aged (75.25±3.01)years old, with a disease course of (17.50±8.50)years. The interviews showed that there were three themes in the area of family support: difficulties in disease management (in terms of diet, exercise, medication, disease surveillance, health knowledge and quitting unhealthy habits), helpfulness of family support in management of above behaviors, differences between family support and support from others (including eating habits, information sharing, emotional support, patient trust, and continuity of support).Conclusions:The elderly diabetic patients in the community have some awareness of health management, but there is still much room for improvement. The supervision and support from family members can help patients improve their self-management and quality of life.

Objective: To understand the status and related knowledge requirements of health emergency literacy among college students in Shaanxi Province, so as to provide the basis for improving college students health emergency literacy. Methods: A total of 2 723 students from 18 colleges and universities in Shaanxi Province were selected by multi stage random sampling and simple random sampling methods in November 2023, and the survey of health literacy in emergency and knowledge requirements of health emergency literacy was conducted. Statistical analysis was carried out by using χ 2 test, Wilcoxon rank sum test, Kruskal-Wallis H test and Logistic regression analysis. Results: About 28.98% of the surveyed college students had a high level of health emergency literacy, which varied by students whether being only one child, whether having left behind experience, with different personality types, whether being student cadres, and with different frequencies of community or social activities ( χ 2=9.15, 7.90, 32.73, 16.29 , 120.25, P <0.05). The equivalence scores of the four dimensions of health emergency literacy from high to low were poisoning and nuclear and radiation (0.84), medical rescue (0.83), infectious disease (0.82), and basic knowledge and behavior ( 0.77 ). Logistic regression analysis found that college students with left-behind experience were negatively correlated with health emergency literacy and its four dimensions ( OR =0.74, 0.72, 0.80, 0.80, 0.83), while personality type (rational type), community or social activity frequency were positively correlated with the cognitive levels of health emergency literacy and its four dimensions among college students ( OR =1.57, 1.50, 1.33, 1.27, 1.38)( P <0.05). There was a higher level of basic knowledge and behavioral cognition among only child college students ( OR =3.73), and female students had a higher level of health emergency literacy, as well as awareness of infectious disease outbreaks and medical rescue ( OR =1.21, 1.28, 1.21)( P <0.05). The radar map showed that the level of health emergency literacy was positive development radar map. About 67.68 % of the students had a high willingness to acquire health emergency literacy knowledge, and the demand for basic health emergency knowledge and behavioral knowledge was the highest (52.37%). Conclusions College students have insufficient health emergency literacy, but they have the highest demand for health emergency. Publicity and education should be strengthened for students with left behind experience, irrational type, and low frequency of community or social activities.

Objective:To investigate the intention to stay on among primary health care workers (PHWs) during the COVID-19 epidemics and its influencing factors.Methods:An online questionnaire survey was conducted among PHWs from 62 primary health institutions in 31 provinces, autonomous regions and municipalities across China selected by multi-stage whole cluster random sampling method between May and October 2022. According to the job position, the PHWs were divided into 5 categories: general practitioners (GPs), nurses, public health doctors, managers and support staff. Intention to stay was measured using the Chinese version of the Intention to Stay Questionnaire. Multiple linear regression model was used to analyze the influencing factors of the intention to stay in PHWs of different occupational categories, including personal factors, work factors, factors related to the COVID-19 and psychological reactions.Results:A total of 3 769 PHWs from 44 community health service centers, 18 township hospitals of 27 provinces/autonomous regions and 4 municipalities participated in this survey. The mean age of participants was (37.4±9.2) years, including 2 971(78.8%) women. The mean score of intention to stay of participants was 21.7±4.1. Compared with GPs, managers had lower intention to stay ( P=0.004). Age, female, in marriage, monthly income, years of primary care service, self-evaluation of unit support function, MSQ-SF score, and PA score were positively correlated with the score of intention to stay (all P<0.05), while PHQ-9 score, EE score, and DP score were negatively correlated with the score of intention to stay (all P<0.05). The MSQ-SF scores of all occupational categories were positively correlated with the scores of intention to stay (all P<0.01). In addition, among GPs, monthly income, years of service in primary care, self-evaluation of unit support function, and PA scores were positively correlated with the score of intention to stay (all P<0.05), while PHQ-9 scores and EE scores were negatively correlated with the score of intention to stay (all P<0.05). Among nurses, age, female gender, monthly income, self-evaluation of unit support function, and PA score were positively correlated with the score of intention to stay (all P<0.05), while EE scores and retention will score were negatively associated with ( P<0.001). Among public health doctors, in marriage was positively correlated with the score of intention to stay ( P=0.018). Among managers, DP score was negatively correlated with the score of intention to stay ( P=0.001). Among support staff, female gender, monthly income, years of primary care service, self-evaluation of unit support function, and PA scores were positively correlated with the score of intention to stay (all P<0.05), while EE score and DP score were negatively correlated with intention to stay (all P<0.05). Conclusions:The intention to stay of PHWs in China during the COVID-19 was at an intermediate level, which was affected by many factors. Among them, job satisfaction was positively correlated with the intention to stay of all occupational categories, and the influencing factors of different occupational categories have some variations.

Objective:To evaluate the effect of family intervention on self-management and glycaemic control in patients with type 2 diabetes mellitus (T2DM).Methods:Clinical interventional trials on the family intervention for T2DM patients were searched in PubMed, Medline, Embase, Cochrance libraries, the CNKI, and the Wan Fang Database from January 2016 to June 2023. Literature was screened according to the inclusion and exclusion criteria. Self-management behavior, BMI and glycated haemoglobin of T2DM patients were used as outcome indicators. Meta-analysis and mapping were performed using Review Manager 5.3 software. A systematic review of the literature on indicators of self-management behavior measured using other instruments except Summary of Diabetes Self-Care Activities.Results:A total of 1 342 relevant papers were retrieved and 13 papers were included in the analysis, involving 1 454 patients, 740 in the intervention group and 714 in the control group. Meta-analysis showed that the inclusion of home-based intervention helped adult T2DM patients to improve self-management ( WMD=5.03, 95% CI:4.43-5.63, P<0.001) and reduce glycated hemoglobin compared with the hospital-patient dichotomous model ( WMD=-0.77, 95% CI:-1.32--0.21, P=0.007), but the effect on BMI was unclear ( WMD=-0.38, 95% CI:-1.04-0.28, P=0.25). The results of the systematic review supported that home-based intervention improving self-management behaviors of adult T2DM patients. Conclusion:Family intervention can improve self-management behaviors and reduce glycated haemoglobin levels in adults T2DM patients.

Objective: To investigate the delay in identification of pulmonary tuberculosis and influencing factors among children and adolescents in Jiaxing City, Zhejiang Province from 2013 to 2022, so as to provide the reference for targeted prevention and control measures. Methods: The information of pulmonary tuberculosis patients in Jiaxing City from 2013 to 2022 were captured from the Tuberculosis Information Management System of Chinese Disease Control and Prevention Information System, including demographics, diagnosis, treatment and etiological results. The delay in identification of pulmonary tuberculosis was analyzed among children and adolescents, and the factors affecting the delay in identification of pulmonary tuberculosis were identified using a multivariable logistic regression model. Results: A total of 2 407 pulmonary tuberculosis cases were reported among children and adolescents in Jiaxing City from 2013 to 2022, including 1 522 males (63.23%). The median age was 21.00 (interquartile range, 4.00) years. There were 410 students (17.03%), and 1 856 cases with non-local household registration (77.11%). There were 596 cases with delay in identification of tuberculosis (24.76%), 895 cases with delay in healthcare-seeking (37.18%) and 128 cases with delay in definitive diagnosis (5.32%). Multivariable logistic regression analysis that children and adolescents who occurred symptoms in the first quarter (OR=1.684, 95%CI: 1.261-2.249), were diagnosed first in county-level medical institutions (OR=3.800, 95%CI: 2.898-4.983) and had positive results of etiological testing (OR=1.534, 95%CI: 1.255-1.874) were more likely to delay in identification of pulmonary tuberculosis. Conclusions The delay in identification of pulmonary tuberculosis is associated with the time of symptom onset, the level of medical institution making first diagnosis, and the results of etiological testing. It is suggested to reinforce the publicity of pulmonary tuberculosis prevention and control, expand the coverage of screening programs and improve the diagnosis capability of medical institutions.

Objective To investigate the effect and underlying mechanism of SULT2B1 in the de-velopment of atherosclerosis(AS).Methods Twelve 8-week-old apolipoprotein E-knockout(apoE-/-)male mice were subjected and fed with a high-fat diet for 12 weeks,and then randomly divided into adeno-associated virus(AAV)-GFP and AAV-shSULT2B1 groups,with 6 animals in each group.In 4 weeks after AAV injection via tail vein,the mice were sacrificed for assessing aortic and aortic root plaque formation by oil red O staining and detecting serum levels of inflam-matory factors and blood lipids.RAW264.7 cells were transfected with adenovirus(Ad)-GFP and Ad-SULT2B1,respectively(n=3).RNA sequencing was performed to detect downstream RNA changes.Then LncRNA gga3-204 was selected for downstream study.After RAW264.7 cells were divided into si-NC group,si-SULT2B1 group,si-Lncgga3-204 group and si-SULT2B1+si-Lncg-ga3-204 group(n=3),and the IL-1β and IL-6 levels were detected in these transfected cells.Results There was no statistically difference in body weight in the mice from the AAV-GFP and AAV-shSULT2B1 groups after high-fat feeding(P＞0.05).Significantly lower serum levels of TC,TG and LDL-C,reduced aortic plaque area[(8.38±1.33)％vs(11.83±1.04)％,P=0.000],and decreased TG content within the aortic root plaque[(12.29±1.54)％vs(17.67±1.53)％,P=0.000]were observed in the AAV-shSULT2B1 group than those in the AAV-GFP group.Ser-um IL-1β and IL-6 levels in the mice of the AAV-shSULT2B1 group than those in the AAV-GFP group(P＜0.01).The AAV-shSULT2B1 group also had obviously lower serum levels of I L-1 βand IL-6 than the AAV-GFP group(P＜0.01).In the RAW264.7 cells from the si-SULT2B1 group,the mRNA levels of IL-1β and IL-6 were notably lower than those in the si-NC group(P＜0.01).LncRNA gga3-204 expression was significantly higher in the Ad-shSULT2B1 group than the Ad-GFP group(P＜0.01).While,the si-SULT2B1 group had statistically higher Lncgga3-204 level than the si-NC group(2.32±0.60 vs 1.19±0.21,P=0.036).The si-Lncgga3-204 group had significantly higher IL-1β and IL-6 mRNA levels than the si-NC group(P＜0.01).The si-SULT2B1+si-Lncgga3-204 group had significantly higher IL-1β and IL-6 mRNA levels than the si-SULT2B1 group(P＜0.05).Conclusion SULT2B1 affects the macrophage inflammatory response via Lncgga3-204,and then affects the progression of AS.

Objective:To screen high-risk population of chronic obstructive pulmonary disease (COPD) and to analyze the risk factors in Haicang District of Xiamen City.Methods:A questionnaire survey was conducted from February 2023 to May 2023 among residents who visited or underwent physical examinations at five community health service centers in Haicang District of Xiamen City selected by cluster sampling method. The self-designed general information questionnaire, COPD population screening questionnaire (COPD-PS) and COPD screening questionnaires (COPD-SQ) were applied in the survey. Individuals with COPD-PS scale>5 or COPD-SQ scale>16 were defined as COPD high-risk group. The association of COPD risk with gender, age, smoking, family history of COPD, history of tuberculosis, history of COVID-19 infection, and using coal/woodstove for cooking or heating was analyzed with chi-square test and binary logistic regression analysis.Results:A total of 4 260 questionnaires were distributed and 4 221 valid questionnaires were collected with a recovery rate of 99.6%. Among all respondents there were 1 904 males (45.11%) and 2 317 females (54.89%); and 217 individuals aged 40-<50 (5.14%), 434 aged 50-<60 (10.28%), 2 194 aged 60-<70 (51.98%), 1 302 aged 70-<80 (30.85%) and 74 aged≥80 (1.76%). The results showed that there were 269 respondents (6.4%) scored≥5 on the COPD-PS scale, 534 residents (12.7%) scored≥16 on the COPD-SQ scale, 646 (15.3%) scored≥5 on the COPD-PS scale or≥16 on the COPD-SQ scale. Male gender ( OR=2.592, 95% CI:2.135-3.146), second-hand smoke exposure ( OR=3.763, 95% CI:2.944-4.810), frequently catching cold before the age of 14 ( OR=3.804, 95% CI:2.927-4.944), history of tuberculosis ( OR=2.575, 95% CI:1.224-5.418), hypertension ( OR=1.547, 95% CI:1.277-1.875), and diabetes ( OR=1.791, 95% CI:1.027-3.121) were independently associated with the high-risk of COPD, while the history of COVID-19 ( OR=0.583, 95% CI:0.476-0.714) was a protective factor for COPD risk. Conclusion:Males, exposure to second-hand smoke, frequently catching cold before the age of 14, history of tuberculosis, hypertension, and diabetes will increase the risk of COPD, while the history of COVID-19 is a protective factor.
