Objective To systematically evaluate the risk prediction models for anastomotic leakage (AL) in patients with esophageal cancer after surgery. Methods A computer-based search of PubMed, EMbase, Web of Science, Cochrane Library, Chinese Medical Journal Full-text Database, VIP, Wanfang, SinoMed and CNKI was conducted to collect studies on postoperative AL risk prediction model for esophageal cancer from their inception to October 1st, 2023. PROBAST tool was employed to evaluate the bias risk and applicability of the model, and Stata 15 software was utilized for meta-analysis. Results A total of 19 literatures were included covering 25 AL risk prediction models and 7373 patients. The area under the receiver operating characteristic curve (AUC) was 0.670-0.960. Among them, 23 prediction models had a good prediction performance (AUC>0.7); 13 models were tested for calibration of the model; 1 model was externally validated, and 10 models were internally validated. Meta-analysis showed that hypoproteinemia (OR=9.362), postoperative pulmonary complications (OR=7.427), poor incision healing (OR=5.330), anastomosis type (OR=2.965), preoperative history of thoracoabdominal surgery (OR=3.181), preoperative diabetes mellitus (OR=2.445), preoperative cardiovascular disease (OR=3.260), preoperative neoadjuvant therapy (OR=2.977), preoperative respiratory disease (OR=4.744), surgery method (OR=4.312), American Society of Anesthesiologists score (OR=2.424) were predictors for AL after esophageal cancer surgery. Conclusion At present, the prediction model of AL risk in patients with esophageal cancer after surgery is in the development stage, and the overall research quality needs to be improved.

Objective:To understand the prevalence, blood pressure control, and influencing factors of hypertension in residents aged 35-75 years in Jiangsu Province, and provide data support and basis for hypertension prevention and treatment.Methods:A stratified cluster sampling method was adopted to conduct community population surveys in 22 districts and counties in 12 prefectures in Jiangsu from 2021 to 2022. A total of 123 531 permanent residents aged 35-75 years were included in the study. The questionnaire survey collected the information about the demographic characteristics, disease history, lifestyle, and control of hypertension of study subjects. Statistical software SPSS 23.0 was used for χ2 test and multivariate logistic regression analysis, and Joinpoint 4.9.1.0 software was used to evaluate the trend of age change. Results:The standardized prevalence of hypertension in study subjects was 46.60%, the prevalence was higher in men than in women, and in rural residents than in urban residents, and the standardized blood pressure control rate was 11.24%, and it was lower in men than in women and in rural residents than in urban residents. The hypertension prevalence and control rates showed increasing trends with age (both P<0.001). The multivariate analysis results showed that being man, older age, being rural resident, higher frequency of alcohol consumption, marital status of being separated and widowed, overweight and obese, abdominal obesity and stroke, diabetes mellitus and dyslipidaemic diseases histories, and family history of hypertension were risk factors for hypertension, and being man, being rural resident, living north area, higher frequency of alcohol consumption, and obesity were risk factors for blood pressure control. Conclusions:The prevalence of hypertension in residents aged 35-75 years in Jiangsu was high, and the rate of blood pressure control was low. It is suggested to take integrated intervention measures, especially in in rural residents and people with low levels of education to reduce the disease burden of the patients.

Objective:To analyze the comorbidity status and influencing factors of hypertension, diabetes, and dyslipidemia among middle-aged and elderly in Jiangsu Province and to provide support for "co-management of the three diseases".Methods:Data originated from the Comprehensive Prevention and Control Project of Cardiovascular and Cerebrovascular Diseases baseline survey in Jiangsu Province. Questionnaire interviews, physical examinations, and laboratory tests were conducted on 136 433 permanent residents aged ≥35 years who participated in the survey from 2021 to 2023. A multinomial logit model was established using SPSS 23.0 to analyze the influencing factors of the three comorbidities.Results:The comorbidity rate of hypertension, diabetes, and dyslipidemia among middle-aged and older adults in Jiangsu Province was 7.3%. Hypertension combined with dyslipidemia was the main comorbidity pattern, and patients with diabetes accounted for the largest proportion. Multinomial logistic regression analysis showed that the risk of being two types of the three comorbidities was higher in male, aging, urban residents, and those with high/technical secondary school, higher frequency of cigarette smoking and alcohol drinking, and longer daily sedentary time; the risk was lower in those with higher the level of physical activity and longer daily sleep time. Among the three types of comorbidities, males with aging, high/technical secondary school, regular smoking/quitting, higher frequency of alcohol drinking, and longer daily sedentary time had higher risk; those with an annual family income of 30 000-99 999 RMB, higher level of physical activity, and the daily sleep time of 7 hours had the lower risk (all P<0.05). Conclusions:The prevention and control of the three comorbidities among middle-aged and older adults in Jiangsu Province still needs strengthening. High-risk groups for the three diseases and comorbidities, such as males, low-income , and high/technical secondary school should be focused on. Middle-aged and older adults are suggested to increase daily physical activity, reduce daily static time, reasonably arrange sleep duration, and quit smoking and drinking as early as possible to maintain a healthy weight.

Objective Based on the theory of"lung governs the skin and hair"in"Yellow Emperor's Inner Classic",this paper analyzes the medication rules of whitening and freckle-removing.The aim of this study is to provide reference for the clinical practice of traditional Chinese medicine(TCM)theory and the medication in TCM cosmetics.Methods"Chinese Medical Classics"was used to search the records of whitening and freckle-related drugs.The frequency,nature,flavor,meridian tropism and compatibility laws of TCM for whitening and freckle-removal were analyzed by statistics and association rules.The network pharmacology research was used to analyze the whitening and freckle-removing effects and mechanisms of high-frequency drugs.Then,the potential active ingredients were analyzed.The whitening and anti-freckle effect was verified through cytotoxicity experiments and melanin content detection.Results A total of 171 external prescriptions were selected in eligible articles,including 261 Chinese medicinals,most of which were pungent and belong to the lung meridian.The most frequently used Chinese medicinals was"Erbai Yixin"(EBYX,Angelicae Dahuricae Radix,Typhonii Rhizoma,Asari Radix et Rhizoma).Network pharmacological analysis showed that the core targets of EBYX for whitening and removing freckles are TP53,EGFR,ALB,etc.,which are mainly involved in oxygen perception and response,skin immune regulation,skin cell growth,differentiation,stress,inflammatory response,and other biological processes.Based on the results of molecular docking,biological analysis proved that the active ingredients of EBYX are chrysophanol,gallic acid and caffeic acid,which have inhibitory effects on the proliferation of melanoma cells and melanin production.Conclusion Most of the ancient prescriptions for whitening and removing freckles are pungent and belong to the lung meridian,which embodies the theory of"lung governs the skin and hair".The high-frequency drug EBYX may play a role by regulating skin redox,immunity and inflammation.The active ingredients of EBYX have an inhibitory effect on melanin formation.This study enriches the scientific connotation of TCM whitening and freckle-removing prescriptions based on the theory of"lung governs the skin and hair",realizes interdisciplinary integration and provides support for the modernization of TCM.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

Objective:To investigate the clinical features of nontuberculous mycobacteria (NTM) disease patients with positive anti-interferon γ (IFN-γ) autoantibody.Methods:Forty-three adult human immunodeficiency virus-uninfected patients with NTM disease hospitalized in Huashan Hospital, Fudan University and Jing′an Branch, Huashan Hospital, Fudan University from July 2021 to August 2023 were included. Clinical data and NTM strain information of the patients were collected. The plasma levels of anti-IFN-γ autoantibodies were detected by enzyme-linked immunosorbent assay, and the patients were divided into antibody positive group and antibody negative group. The clinical characteristics and laboratory examination results between the two groups were compared. The independent sample t test, Mann-Whitney U test and chi-square test were used for statistical analysis. Multivariate logistic regression analysis was used to determine the correlation factors of positive anti-IFN-γ autoantibodies. Results:Among the 43 patients, 13 cases (30.2%) were positive for anti-IFN-γ autoantibodies and 30 cases (69.8%) were negative. The proportions of patients with NTM disseminated infection (9/13 vs 30.0%(9/30))and combined bacterial infection (5/13 vs 6.7%(2/30)) in antibody positive group were both higher than those in antibody negative group, and the differences were both statistically significant ( χ2=5.74 and 6.73, respectively, both P<0.05). The white blood cell count, platelet count, the proportion of platelet count >350×10 9/L of antibody positive patients were all higher than those of antibody negative group, while the white sphere ratio was lower than that of antibody negative group, with statistical significance ( t=2.42, 3.02, χ2=9.77 and t=3.66, respectively, all P<0.05). Erythrocyte sedimentation rate, C-reactive protein, procalcitonin, globulin, immunoglobulin G, immunoglobulin A and immunoglobulin M in antibody positive patients were all higher than those in antibody negative group, and the differences were all statistically significant ( U=99.50, 112.00, 115.50, 61.50, 76.50, 99.00 and 83.00, respectively, all P<0.05). Mycobacterium abscessus complex (seven cases and 11 cases, respectively) and Mycobacterium avium complex (five cases and 13 cases, respectively) were the main isolated strains in antibody positive and antibody negative patients. Multivariate logistic regression analysis showed that combined with bacterial infection (odds ratio ( OR)=21.83, 95% confidence interval ( CI) 1.94 to 245.71), NTM disseminated infection ( OR=7.64, 95% CI 1.10 to 53.26), platelet count>350×10 9/L ( OR=14.31, 95% CI 1.91 to 107.04) were risk factors for anti-IFN-γ autoantibodies positive (all P<0.05). Conclusions:Patients with positive anti-IFN-γ autoantibodies have higher probability of having elevated levels of systemic inflammation. Anti-IFN-γ autoantibody test is recommended for patients with NTM disease who present with co-bacterial infection, NTM disseminated infection, or elevated platelet count (>350×10 9/L).

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.
