ObjectiveTo investigate whether visceral fat area （VFA） is an independent risk factor for significant liver fibrosis in patients with nonalcoholic fatty liver disease （NAFLD） based on clinical data， and to establish an effective diagnostic model. MethodsA total of 222 NAFLD patients who attended Department of Hepatology， Guangdong Provincial Hospital of Traditional Chinese Medicine， from January 2021 to April 2025 were enrolled， and according to liver stiffness measurement （≥8 kPa or not）， they were divided into significant fibrosis group and non-significant fibrosis group. Propensity score matching （PSM） was performed at a ratio of 1∶1 to balance the baseline data between the two groups. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups； the chi-square test was used for comparison of categorical data between groups. A Spearman correlation analysis was used to determine the correlation of VFA and other indicators with significant liver fibrosis； univariate and multivariate logistic regression analyses were used to identify whether VFA was an independent risk factor for significant liver fibrosis in NAFLD patients， and the receiver operating characteristic （ROC） curve was plotted to assess the predictive performance of related indicators. ResultsA total of 45 patients with significant liver fibrosis and 177 patients without significant liver fibrosis were enrolled， and after PSM， 90 patients （45 pairs） were finally included in analysis. Compared with the non-significant fibrosis group， the significant fibrosis group had significantly higher levels of body mass index （BMI）， fasting blood glucose （FBG）， glycated hemoglobin （HbA1c）， uric acid （UA）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， gamma-glutamyl transpeptidase （GGT）， controlled attenuation parameter （CAP）， and VFA， as well as a significantly higher proportion of patients with visceral fat obesity or three or more metabolic risk factors （all P<0.05）. VFA， BMI， AST， and HbA1c were strongly correlated with significant liver fibrosis （all r>0.5， all P <0.05）， and ALT， GGT， UA， FBG， and CAP were significantly positively correlated with significant liver fibrosis （r=0.3　—　0.5， all P<0.05）. VFA （odds ratio ［OR］=1.040， 95% confidence interval ［CI］： 1.018　—　1.062， P<0.05）， FBG （OR=2.372， 95%CI： 1.199　—　4.691， P<0.05）， and AST （OR=1.032， 95%CI： 1.003　—　1.058， P<0.05） were independent risk factors for significant liver fibrosis in NAFLD patients. The new diagnostic model based on VFA， FBG， and AST （with an area under the ROC curve ［AUC］ of 0.907） had a significantly better performance than aspartate aminotransferase-to-platelet ratio index （AUC=0.834）， fibrosis-4 （AUC=0.660）， triglyceride-glucose index （AUC=0.656）， and NAFLD fibrosis score （AUC=0.768） in predicting significant liver fibrosis in NAFLD patients （all P<0.05）. ConclusionVFA is an independent risk factor for significant liver fibrosis in NAFLD patients， and the noninvasive diagnostic model based on VFA， FBG， and AST can effectively predict the onset of significant liver fibrosis in NAFLD patients.

[摘 要] 目的：探讨麻疹-流行性腮腺炎-风疹联合减毒活疫苗（MMR）通过诱导免疫原性细胞死亡（ICD）对三阴性乳腺癌（TNBC）的免疫调节机制。方法：体外实验采用CCK-8法检测MMR对TNBC细胞4T1和MDA-MB-231存活率的影响，免疫荧光法检测MDA-MB-231细胞中钙网蛋白（CALR）表达，磷钼酸比色法检测MDA-MB-231细胞内ATP的含量，ELISA检测细胞上清液中高迁移率族蛋白B1（HMGB1）的表达水平，通过GEPIA网站分析CALR和HMGB1对乳腺癌患者生存期的影响。体内实验中经皮下注射4T1-Luc细胞于雌性BALB/c小鼠乳腺脂肪垫构建TNBC小鼠模型。设Control组、盐酸阿霉素（Dox）组、MMR组，按照分组每两天静脉给药1次，连续给药3次。动物活体成像系统观察肿瘤体积变化；记录小鼠体质量及各器官指数初步评估疫苗安全性；H-E染色观察肿瘤病理变化；免疫组化和Western blotting检测肿瘤中CALR和HMGB1蛋白的表达。流式细胞术分析小鼠脾T淋巴细胞亚群及肿瘤树突状细胞和巨噬细胞比例；免疫组化检测肿瘤CD8+ T淋巴细胞浸润；ELISA检测血清中促炎细胞因子IL-6和TNF-α含量。结果：MMR对4T1细胞的活性抑制作用较弱；MMR对MDA-MB-231细胞抑制率达90.39%（P < 0.001）。与Control组相比，MMR组MDA-MB-231细胞中ICD相关蛋白（CALR、ATP、HMGB1）表达上调（P < 0.001）。GEPIA网站分析表明，CALR和HMGB1高表达的患者总生存期有所延长。MMR延缓了荷瘤小鼠肿瘤体积增长（P < 0.001），延长小鼠的生存期，且28 d内MMR组荷瘤小鼠体重与Control组无显著性差异（P > 0.05）；H-E染色显示，与Control组相比，MMR组小鼠肿瘤组织坏死区域扩大且有免疫细胞浸润；MMR上调肿瘤ICD相关蛋白CALR、HMGB1的表达水平；MMR组脾CD4+、CD8+ T淋巴细胞及肿瘤树突状细胞和M1型巨噬细胞的比例增加（P < 0.05），CD8+ T淋巴细胞在肿瘤组织中的浸润增加（P < 0.001），且促炎细胞因子IL-6和TNF-α水平升高（P < 0.01）。结论：MMR减毒活疫苗对TNBC的抗肿瘤作用可能与诱导肿瘤发生ICD进而激活抗肿瘤免疫相关。

Effective symptom management can alleviate the physical and psychological distress experienced by patients with cancer, improve quality of life, and contribute to treatment adherence and improve clinical outcomes. However, most existing guidelines are developed for healthcare professionals, and patients and the public have limited access to standardized and comprehensible guidance on symptom management. To address this gap and to facilitate effective communication and shared decision-making, this study proposes the development of a patient version of the cancer symptom management guideline. The development process will adhere to the methodological framework recommended by the Guidelines International Network and the World Health Organization. The GRADE approach will be employed to assess the certainty of evidence and to formulate recommendations. In addition, the process will be informed by the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) instrument and the Reporting Items for Practice Guidelines in Healthcare-Public or Patient Versions of Guidelines (RIGHT-PVG). This protocol outlines the establishment of the guideline working group, the identification and prioritization of key questions, evidence retrieval and appraisal, and the formulation of recommendations, with the aim of ensuring methodological rigor and transparency in the development of the patient guideline and providing methodological reference for similar guideline initiatives.

Fusarium head blight (FHB), caused by Fusarium graminearum, not only leads to severe yield losses but also poses a threat to food safety due to the mycotoxins produced by the pathogen. Since this disease is preventable but not curable, the current control mainly relies on chemical fungicides, the long-term use of which may lead to pathogen resistance and environmental pollution. To develop green control methods, we screened 13 biocontrol strains from the rhizosphere soil of wheat, among which strain No. 12 (identified as Pythium aphanidermatum) showed significant antifungal effects. In the plate confrontation test, this strain reduced the colony diameter of the pathogen by 69.2% (1.47 mm vs. 4.78 mm in the control group), with an inhibition rate of 77% (P < 0.01). Microscopic observation revealed obvious deformations in the pathogen hyphae, suggesting a lysing effect. The coleoptile experiment further confirmed that the pre-treatment with this strain reduced the incidence rate to 0. These findings provide new candidate strains for the biocontrol of FHB and offer a scientific basis for reducing the use of chemical fungicides and promoting sustainable agricultural development.

Objective To understand the willingness of general practitioner(GP) to enhance working competence in community healthcare centers in Shanghai and provide a basis for the competence training of GPs in community healthcare centers. Methods In August 2023,GPs were selected from some community healthcare centers in Shanghai and their willingness to enhance working competence were studied by a questionnaire survey.The survey included 39 secondary indicators in three dimensions:general practice theory,skills,and humanity. Results A total of 1 192 GPs completed the questionnaire,with an effective rate of 100%.The total score of GPs' willingness to enhance their working competence was 258.45±80.93,and the mean score of the three dimensions was 6.63±2.08.The score for the general practice theory was the highest (6.92±1.95),while that for general practice humanity was the lowest (6.44±2.34) among the three dimensions.The score of willingness to enhance working efficiency differed across different age ranges (P<0.001),professional titles (P<0.001),years of work (P<0.001),and educational backgrounds of GPs (P=0.039).Those with the age younger than 30 years old,junior professional titles,less than 5 years of work experience,and a college degree or below had the highest willingness score to enhance their working competence.Among the top three secondary indicators of willingness score in each dimension,the top three methods of working competence enhancement were community general practice and specialized healthcare services combined with outpatient learning,flexible further training,and continuing education courses.Conclusions There is an urgent need for young GPs in community healthcare centers in Shanghai to enhance their working competence.Targeted enhancement plans can be provided to different groups of GPs with different characteristics through community general practice and specialized healthcare services combined with outpatient learning,flexible further training,and continuing education courses,which can further enhance the ability and quality of the GP team.

Objective To explore the relationship between the coagulation and fibrinolysis function in the early pregnancy and the occurrence of gestational diabetes mellitus(GDM)in women with different pre pregnancy body mass indexes(BMI).Methods 290 pregnant women undergoing the prenatal check ups at the Second Affiliated Hospital of Kunming Medical University from September 2023 to February 2024 were selected.Pre pregnancy BMI,age,family genetic history,parity,parity,and early pregnancy coagulation and fibrinolysis function test results were collected.Based on whether GDM had occurred,they were divided into GDM group(n=72)and non GDM group(n=218),and further divided into low weight GDM group(n=8),low weight non GDM group(n=29),normal weight GDM group(n=39),normal weight non GDM group(n=145),overweight/obesity GDM group(n=25),overweight/obesity non GDM group(n=44)based on pre pregnancy BMI.Basic data comparison was conducted on the total population and BMI groups.Independent sample t-test or Mann Whitney U test was used for quantitative data,and chi square test or Fisher's exact probability method was used for qualitative data.Multivariate logistic regression was used to correct the influencing factors.Results After adjusting the confounding factors such as age,family history,and pre pregnancy BMI,APTT was negatively correlated with the occurrence of GDM in the overall population(P<0.05,OR=0.840),while FIB was positively correlated with GDM(P<0.01,OR=2.598).In low body weight recombination,APTT was negatively correlated with GDM(P<0.05,OR=0.483),FIB was positively correlated with GDM(P<0.05,OR=82.501),while there was no significant correlation between APTT,FIB and GDM after adjusting the age,family history,and pre pregnancy BMI;In the normal weight group,APTT was negatively correlated with GDM(P<0.01,OR=0.786)and FIB was positively correlated with GDM(P<0.05,OR=2.413).However,after adjusting the age,family history,and pre pregnancy BMI,APTT remained negatively correlated with GDM(P<0.05,OR=0.812)and FIB remained positively correlated with GDM(P<0.05,OR=2.391);In the overweight/obese group,TT was negatively correlated with GDM(P<0.05,OR=0.510),while there was no significant correlation between TT and GDM after adjusting the age,family history,and pre pregnancy BMI.Conclusion In the normal weight population,APTT is negatively correlated with the occurrence of GDM,while FIB is positively correlated with the occurrence of GDM;In the low weight and overweight/obese populations,coagulation and fibrinolysis related indicators are greatly influenced by BMI and have no significant correlation with the occurrence of GDM.

Patients suffering from stage Ⅳ periodontitis manifest substantial alveolar bone destruction and pronounced tooth loss,fre-quently accompanied by masticatory dysfunction,occlusal disorder and tooth displacement or torsion.Standard periodontal interventions alone are insufficient to stabilize the condition,address masticatory dysfunction,and enhance patients'quality of life.Hence,intricate reconstructive and interdisciplinary regimens,encompassing orthodontic treatment,are often indispensable.Orthodontic therapy can op-timize the masticatory function and esthetic appearance of patients,and promote periodontal well-being.However,individuals with stageⅣ periodontitis present with inadequate periodontal support tissue and a heightened risk profile,rendering their orthodontic management a considerable clinical challenge.This article reviews the orthodontic considerations and optimal timing for intervention in patients with stage Ⅳ periodontitis and presents a representative case of combined periodontal-orthodontic-orthognathic treatment for pe-riodontitis(stage Ⅳ,grade C),in order to provide reference for periodontists and orthodontists.

Objective To compare the safety and efficacy of minimally invasive coronary artery bypass grafting (MICS CABG) and traditional CABG in patients with coronary heart disease (CHD) and diabetes mellitus (DM). Methods From 2019 to 2021, the patients who received CABG by the same medical group in the Minimally Invasive Cardiac Surgery Center of Beijing Anzhen Hospital were retrospectively enrolled. According to the surgery methods, the patients were divided into two groups: a MICS CABG group and a conventional group. The perioperative and postoperative follow-up data of patients were collected. The main observation results included all cause death events, myocardial infarction, cerebrovascular, revascularization, and adverse wound healing. Results According to the inclusion and exclusion criteria, 140 patients were enrolled, including 66 patients in the MICS CABG group [56 males and 10 females, aged (61.83±8.94) years], and 74 patients in the conventional group [55 males and 19 females, aged (58.61±8.26) years]. Compared with the conventional group, patients in the MICS CABG group had longer median surgical time (4.50 h vs. 4.00 h, P=0.005), less intraoperative bleeding (600.00 mL vs. 700.00 mL, P=0.020), and a lower rate of secondary debridement and suturing of surgical wounds (4.5% vs. 16.2%, P=0.023). The median follow-up time was 2.54 years. There was no statistically significant difference in the cumulative incidence of major adverse cardiac and cerebrovascular events (7.6% vs. 5.4%), all-cause mortality (0.0% vs. 0.0%), myocardial infarction (3.0% vs. 2.7%), cerebrovascular events (4.5% vs. 2.7%), or revascularization (0.0% vs. 0.0%) between the two groups of patients during the postoperative follow-up (P>0.05). Conclusion MICS CABG can achieve the same revascularization effect as traditional CABG in patients with CHD and DM. MICS CABG can effectively reduce adverse clinical outcomes or complications such as adverse chest wound healing and slow postoperative recovery of body function in patients with DM.

Traditional Chinese medicine(TCM)serves as a treasure trove of ancient knowledge,holding a crucial position in the medical field.However,the exploration of TCM's extensive information has been hindered by challenges related to data standardization,completeness,and accuracy,primarily due to the decen-tralized distribution of TCM resources.To address these issues,we developed a platform for TCM knowledge discovery(TCMKD,https://cbcb.cdutcm.edu.cn/TCMKD/).Seven types of data,including syndromes,formulas,Chinese patent drugs(CPDs),Chinese medicinal materials(CMMs),ingredients,targets,and diseases,were manually proofread and consolidated within TCMKD.To strengthen the integration of TCM with modern medicine,TCMKD employs analytical methods such as TCM data mining,enrichment analysis,and network localization and separation.These tools help elucidate the molecular-level commonalities between TCM and contemporary scientific insights.In addition to its analytical capabilities,a quick question and answer(Q&A)system is also embedded within TCMKD to query the database efficiently,thereby improving the interactivity of the platform.The platform also provides a TCM text annotation tool,offering a simple and efficient method for TCM text mining.Overall,TCMKD not only has the potential to become a pivotal repository for TCM,delving into the pharmaco-logical foundations of TCM treatments,but its flexible embedded tools and algorithms can also be applied to the study of other traditional medical systems,extending beyond just TCM.
