OBJECTIVE: To investigate the effectiveness of free palmaris longus tendon graft reconstruction in the treatment of gouty tophus erosion lesions in flexor tendon of wrist and hand. METHODS: A retrospective analysis was conducted on 8 patients with gouty tophus erosion lesions in flexor tendon of wrist and hand who underwent free palmaris longus tendon graft reconstruction between June 2017 and December 2023. All patients were male, aged 22-65 years, with an average of 45.9 years. The duration of gout history ranged from 2 to 18 years, with an average of 8.8 years. The duration from the discovery of gouty tophus to operation ranged from 12 to 26 months, with an average of 17.6 months. The gouty tophus eroded the flexor pollicis longus tendon in 4 cases, with Verdan flexor tendon zones being Ⅰ-Ⅱ in 1 case and Ⅳ-Ⅴ in 3 cases. The flexor digitorum profundus tendons were affected in 2 cases for the index finger, 1 for the middle finger, and 1 for the ring finger, all located in zone Ⅳ-Ⅴ. The long axis of the gouty tophus ranged from 2.3 to 4.5 cm, with an average of 3.4 cm. All 8 patients presented with limited finger flexion and extension. Among them, 4 cases were accompanied by median nerve compression symptoms, and 1 case had associated bone and joint destruction in the hand. The total active motion (TAM) of the affected finger was (81.3±30.2)° before operation according to the hand function evaluation criteria for tendon repair by the Chinese Society of Hand Surgery of the Chinese Medical Association, and the functional evaluation was poor. The harvested palmaris longus tendon intraoperatively was 7-9 cm in length. RESULTS: Surgical incisions in all 8 patients healed by first intention, with no infections, graft non-union, or significant adhesion complications. All patients were followed up 8-25 months, with an average of 14.8 months. Numbness symptoms resolved in all 4 patients who presented with median nerve compression symptoms. Patients did not experience wrist pain or other discomfort, and function was not compromised. At last follow-up, according to the hand function evaluation criteria for tendon repair by the Chinese Society of Hand Surgery of the Chinese Medical Association, the TAM of 8 patients was (197.5±55.8)°, which significantly improved when compared with that before operation ( t=11.638, P<0.001); the hand function of 1 patient with gouty tophus in zone Ⅰ-Ⅱ flexor pollicis longus tendon was good, and the other 7 patients were excellent. CONCLUSION Free palmaris longus tendon graft reconstruction demonstrates good effectiveness in treating gouty tophus erosion lesions in flexor tendon of wrist and hand.

OBJECTIVE: To explore the effectiveness of multi-segment inverted Y-shaped vein transplantation using the anterior lateral malleolar venous network for repair of amputated palm injury distal to the superficial palmar arch. METHODS: Between September 2018 and July 2023, 5 patients with amputated palm injury distal to the superficial palmar arch were treated. There were 3 males and 2 females with an average age of 35.4 years (range, 29-52 years). The time from injury to admission was 1-6 hours (mean, 3.2 hours). The multi-segment inverted Y-shaped vein transplantation in the anterior lateral malleolar venous network were used to repair the common and proper palmar digital arteries; the another anterior lateral malleolar venous network was used to repair the dorsal vein of the hand. The soft tissue defect of dorsal hand in 1 patient was repaired with the pedicled ilioinguinal flap, and the wound at the donor site was directly sutured. Postoperative treatment included anti-infection therapy, antispasmodic therapy, and thrombosis prevention measures. RESULTS: The partial necrosis of the fingertip of the thumb occurred in 1 case, and the marginal necrosis of the abdominal flap after operation occurred in 1 case. The remaining fingers showed good blood supply with normal tension. The incision at donor site of the abdominal flap healed by first intention. All patients were followed up 8-41 months (median, 19 months). At last follow-up, the hand contour was satisfactory; the grasping function, opposition function, and proprioception recovered, and two-point discrimination ranged from 5 to 7 mm (mean, 6 mm). According to the upper extremity function evaluation criteria issued by Hand Surgery Society of the Chinese Medical Association, the functional outcomes were excellent in 3 cases, good in 1 case, and fair in 1 case. CONCLUSION The multi-segment inverted Y-shaped vein transplantation using the anterior lateral malleolar venous network for repairing defects in the common and proper palmar digital arteries distal to the superficial palmar arch offers advantages such as superficial location, flexible harvesting, and high compatibility. This technique has demonstrated favorable outcomes in complex transmetacarpal amputation reconstruction.

BACKGROUND: Hypertension is a serious chronic disease that can significantly lead to various cardiovascular diseases, affecting vital organs such as the heart, brain, and kidneys. Our goal is to predict the risk of new onset hypertension using machine learning algorithms and identify the characteristics of patients with new onset hypertension. METHODS: We analyzed data from the 2011 China Health and Nutrition Survey cohort of individuals who were not hypertensive at baseline and had follow-up results available for prediction by 2015. We tested and evaluated the performance of four traditional machine learning algorithms commonly used in epidemiological studies: Logistic Regression, Support Vector Machine, XGBoost, LightGBM, and two deep learning algorithms: TabNet and AMFormer model. We modeled using 16 and 29 features, respectively. SHAP values were applied to select key features associated with new onset hypertension. RESULTS: A total of 4,982 participants were included in the analysis, of whom 1,017 developed hypertension during the 4-year follow-up. Among the 16-feature models, Logistic Regression had the highest AUC of 0.784(0.775∼0.806). In the 29-feature prediction models, AMFormer performed the best with an AUC of 0.802(0.795∼0.820), and also scored the highest in MCC (0.417, 95%CI: 0.400∼0.434) and F1 (0.503, 95%CI: 0.484∼0.505) metrics, demonstrating superior overall performance compared to the other models. Additionally, key features selected based on the AMFormer, such as age, province, waist circumference, urban or rural location, education level, employment status, weight, WHR, and BMI, played significant roles. CONCLUSION We used the AMFormer model for the first time in predicting new onset hypertension and achieved the best results among the six algorithms tested. Key features associated with new onset hypertension can be determined through this algorithm. The practice of machine learning algorithms can further enhance the predictive efficacy of diseases and identify risk factors for diseases.

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.

BACKGROUND: Arsenic trioxide (ATO) is indicated as a broad-spectrum medicine for a variety of diseases, including cancer and cardiac disease. While the role of ATO in hepatic ischemia/reperfusion injury (HIRI) has not been reported. Thus, the purpose of this study was to identify the effects of ATO on HIRI. METHODS: In the present study, we established a 70% hepatic warm I/R injury and partial hepatectomy (30% resection) animal models in vivo and hepatocytes anoxia/reoxygenation (A/R) models in vitro with ATO pretreatment and further assessed liver function by histopathologic changes, enzyme-linked immunosorbent assay, cell counting kit-8, and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay. Small interfering RNA (siRNA) for extracellular signal-regulated kinase (ERK) 1/2 was transfected to evaluate the role of ERK1/2 pathway during HIRI, followed by ATO pretreatment. The dynamic process of autophagic flux and numbers of autophagosomes were detected by green fluorescent protein-monomeric red fluorescent protein-LC3 (GFP-mRFP-LC3) staining and transmission electron microscopy. RESULTS: A low dose of ATO (0.75 μmol/L in vitro and 1 mg/kg in vivo ) significantly reduced tissue necrosis, inflammatory infiltration, and hepatocyte apoptosis during the process of hepatic I/R. Meanwhile, ATO obviously promoted the ability of cell proliferation and liver regeneration. Mechanistically, in vitro  studies have shown that nontoxic concentrations of ATO can activate both ERK and phosphoinositide 3-kinase-serine/threonine kinase (PI3K-AKT) pathways and further induce autophagy. The hepatoprotective mechanism of ATO, at least in part, relies on the effects of ATO on the activation of autophagy, which is ERK-dependent. CONCLUSION Low, non-toxic doses of ATO can activate ERK/PI3K-AKT pathways and induce ERK-dependent autophagy in hepatocytes, protecting liver against I/R injury and accelerating hepatocyte regeneration after partial hepatectomy.

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 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 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.
