ObjectiveTo investigate the risk factors for bleeding within 5 days and 2 weeks after endoscopic variceal ligation （EVL） or endoscopic cyanoacrylate injection （ECI） for the treatment of esophagogastric varices in patients with liver cirrhosis， as well as the safety of EVL/ECI in patients with thrombocytopenia. MethodsA total of 489 patients with liver cirrhosis and esophagogastric varices who underwent EVL/ECI in Guangzhou Eighth People’s Hospital， Guangzhou Medical University， from January 2018 to December 2023 were enrolled as subjects， and according to the presence or absence of bleeding after surgery， they were divided into bleeding group and non-bleeding group. The risk factors for bleeding within 5 days and 2 weeks after surgery were analyzed. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between groups， and the chi-square test or the continuity-corrected chi-square test was used for comparison of categorical data between groups； the receiver operating characteristic （ROC） curve was plotted to determine the cut-off value of MELD score； a multivariate logistic regression analysis was used to identify the independent risk factors for postoperative bleeding. ResultsThere were no significant differences in the bleeding rates within 5 days and 2 weeks after EVL/ECI between the 386 patients with a platelet count of ≥50×10⁹/L and the 103 patients with a platelet count of （25 — 49）×10⁹/L （5 days： 1.94% vs 2.85%， P=0.870； 2 weeks： 2.91% vs 4.92%， P=0.544）. The overall bleeding rate was 2.66% （13/489） and 4.50% （22/489）， respectively， within 5 days and 2 weeks after EVL/ECI. The multivariate logistic regression analysis showed that MELD score was an independent risk factor for bleeding within 5 days （odds ratio ［OR］=3.726， 95% confidence interval ［CI］： 1.214 — 11.429， P=0.021） and 2 weeks （OR=5.760， 95%CI： 1.779 — 18.651， P=0.003） after EVL/ECI， while hemoglobin （Hb） was a protective factor against bleeding within 5 days （OR=0.972， 95%CI： 0.948 — 0.996， P=0.025） and 2 weeks （OR=0.976， 95%CI： 0.957 — 0.995， P=0.016） after surgery； portal vein tumor thrombus （OR=2.667， 95%CI： 1.000 — 7.117， P=0.050） was an independent risk factor for bleeding within 2 weeks after surgery， while platelet count ［（25 — 49）×10⁹/L］ was not a risk factor for postoperative bleeding （P>0.05）. ConclusionBoth EVL and ECI have good safety in patients with liver diseases and grade 3 thrombocytopenia. MELD score is an independent risk factor for bleeding within 5 days and 2 weeks after EVL/ECI， while Hb is a protective factor； portal vein tumor thrombus is an independent risk factor for bleeding within 2 weeks after surgery.

Objective To develop the Ego Depletion Scale for Type 2 Diabetes Patients and evaluate its reliability and validity,and to provide a specific assessment tool for evaluating ego-depletion in self-management.Methods Guided by the self-control strength model,the initial scale was constructed through literature review,semi-structured interviews,2 rounds of expert consultation,and a pilot survey.A convenience sampling method was employed to recruit 460 patients with Type 2 Diabetes from the endocrinology department of a tertiary hospital in Wuhan,Hubei Province,between April and July 2024.They were randomly divided into 2 subsets for exploratory factor analysis and confirmatory factor analysis.Results A total of 451 valid questionnaires were collected.Exploratory factor analysis extracted 6 common factors,with a cumulative variance contribution of 73.231％.In confirmatory factor analysis,an item was deleted due to failing to meet the standardized loading value criterion.The revised Ego Depletion Scale for Type 2 Diabetes Patients comprised 6 dimensions and 22 items.The total Cronbach's α coefficient was 0.911;split-half reliability was 0.744;the content validity index was 0.860.Correlation coefficients between the total score and scores of each dimension of the scale and the total score of the Self-Regulatory Fatigue Scale ranged from 0.558 to 0.946(P＜0.001).Conclusion The scale exhibits robust reliability and validity,serving as a scientifically instrument for assessing ego depletion in patients with Type 2 Diabetes.

OBJECTIIVE:The positive role of exercise intervention in the prevention and treatment of sarcopenia has received widespread attention,but the optimal exercise dose for elderly sarcopenic patients still needs to be further determined.The article explored the dose-effect relationship between various elements of exercise prescription and the improvement of muscle mass,muscle strength and physical function in community-dwelling elderly patients with sarcopenia,aiming to provide scientific support for the development of exercise prescription for community-dwelling elderly patients with sarcopenia.METHODS:Literature published from the inception to October 9,2024 in PubMed,EMBASE,Scopus,Web of Science,CNKI,WanFang,VIP,and CBMdisc databases was systematically searched.Meta-analysis was performed using RevMan 5.3 software.Standardized mean difference(SMD)and its 95％CI were used as effect statistics.RESULTS:(1)A total of 11 randomized controlled trials were included,with 348 in the trial group and 304 in the control group.(2)Meta-analysis results showed that exercise improved appendicular skeletal muscle mass index,grip strength,and walking speed in elderly patients with sarcopenia(SMDs 0.46,0.63,0.67,P＜0.05).(3)When the frequency of exercise was 2-3 days/week,appendicular skeletal muscle mass index(SMD=0.57,95％CI:0.28-0.86,P＜0.001),grip strength(SMD=0.70,95％CI:0.37-1.02,P＜0.001),and walking speed(SMD=0.69,95％CI:0.20-1.18,P=0.006)were effectively improved in elderly patients with sarcopenia.(4)When the duration of exercise was 25-60 minutes per session,appendicular skeletal muscle mass index(SMD=0.28,95％CI:0.07-0.50,P=0.01),grip strength(SMD=0.37,95％CI:0.16-0.59,P＜0.001),and walking speed(SMD=0.39,95％CI:0.06-0.73,P=0.02)were effectively improved in elderly patients with sarcopenia.(5)When the exercise intensity was moderate,appendicular skeletal muscle mass index(SMD=0.69,95％CI:0.35-1.03,P＜0.001),and grip strength(SMD=0.36,95％CI:0.09-0.64,P=0.009),and walking speed(SMD=0.91,95％CI:0.34-1.47,P=0.002)were effectively improved in elderly patients with sarcopenia.(6)When the dose of exercise cycle was 8-12 weeks,appendicular skeletal muscle mass index(SMD=0.42,95％CI:0.20-0.64,P＜0.001),grip strength(SMD=0.45,95％CI:0.26-0.64,P＜0.001),and walking speed(SMD=0.76,95％CI:0.27-1.25,P=0.002)were effectively improved in elderly patients with sarcopenia.CONCLUSION:Active,regular exercise can improve muscle health in older adults with sarcopenia.It is recommended that older patients with sarcopenia exercise at least 2 to 3 days per week,25 to 60 minutes each time,lasting for 8 to 12 weeks of moderate intensity exercise to improve muscle health.

Objective:To evaluate the application value of mini-clinical evaluation exercise-direct observation of procedural skills (Mini-CEX-DOPS) in the assessment of the Simodont digital virtual simulation training system in general dentistry residency training.Methods:A total of 172 general dentistry residents at West China Hospital of Stomatology, Sichuan University, from January 2023 to December 2024 were enrolled and randomly assigned to two groups using a random number table. The control group received traditional teaching, and the training group received Simodont digital virtual simulation training and traditional teaching. Through clinical treatment of real patients, differences between groups were compared in Mini-CEX+DOPS assessment scores, exit examination scores, and teaching satisfaction. A statistical analysis was performed using SPSS 22.0 software. Categorical data were analyzed using the chi-square test, and inter-group comparisons were performed using the independent-samples t test with a significance level of α=0.05. Results:There were no significant differences in Mini-CEX scores between the two groups at the beginning of residency training at the Department of General Dentistry ( P>0.05). At the end of residency training, the Mini-CEX scores of the training group in clinical consultation, physical examination, and humanistic care were higher than those of the control group ( P<0.05); the comprehensive competency score of the training group was (7.65±0.50), while that of the control group was (6.84±0.43). The comprehensive competency scores of both groups were higher at the end of residency training compared to that at the beginning of residency training ( P<0.05). At the beginning of residency training, there were no significant differences in DOPS assessment scores between the two groups ( P>0.05). At the end of residency training, the DOPS evaluation scores were higher in the training group than in the control group ( P<0.05). The overall operation skill scores for the training and control groups were (7.61±0.45) and (6.90±0.31), respectively. The DOPS scores of both groups were higher at the end of residency training compared to those at the beginning of residency training ( P<0.05). The theoretical evaluation, professional skill, and medical record writing quality scores of the training group were higher than those of the control group ( P<0.05); the professional skill scores of the training and control groups were (86.32±4.12) and (77.39±4.58), respectively. The overall satisfaction of the training group was higher than that of the control group [95.35％(82/86) vs. 70.93％(61/86), P<0.05]. Conclusions:Based on the formative evaluation system of Mini-CEX+DOPS, the Simodont digital virtual simulation training system can improve the training effectiveness, physician satisfaction, teaching quality, and patient satisfaction in general dentistry residency training. This approach has significant application value and promising prospects for broader promotion.

Objective:This study aims to explore the independent and interactive effects of childhood trauma (CT) and major depressive disorder (MDD) on amygdala subregion volumes and to examine whether volumetric changes in these subregions mediate the relationship between CT and depressive severity.Methods:A total of 129 MDD patients and 127 age- and sex-matched healthy controls were recruited from Nanjing Brain Hospital between October 2022 and November 2024. All participants underwent 3D-T 1 weighted MRI scans,and amygdala subregions were segmented using the FreeSurfer software. Depressive and anxiety symptoms were assessed with the 17-item Hamilton Depression Rating Scale (HAMD 17) and the Hamilton Anxiety Scale (HAMA),respectively. Childhood trauma exposure was evaluated via the Childhood Trauma Questionnaire (CTQ). Generalized linear models (GLM) were applied to analyze the main and interactive effects of MDD diagnosis (depression/healthy controls) and CT (presence/absence),adjusting for age,estimated intracranial volume,sex,medication history,and education years. Partial correlation and mediation analyses were conducted to explore associations between amygdala subregion volumes and clinical measures in MDD patients. Results:MDD diagnosis was independently associated with increased volumes in the right central nucleus ( Wald χ2=9.09, P=0.026) and medial nucleus ( Wald χ2=10.08, P=0.026). CT exposure was independently associated with reduced volumes in the right central nucleus ( Wald χ2=7.99, P=0.047) and medial nucleus ( Wald χ2=9.20, P=0.047). No significant interaction effects between MDD and CT were observed in any amygdala subregion. Mediation analysis revealed that reduced right medial nucleus volume partially mediated the relationship between total CTQ scores and depressive severity (proportion mediated: 26.69%,95% CI=0.002-0.060) and mediated the association between emotional neglect and depressive severity (proportion mediated: 26.75%,95% CI=0.006-0.150). Such mediating effects were not found for the right central nucleus. Conclusion:CT and MDD exhibit divergent patterns of influence on amygdala subregions. CT is linked to volumetric reductions,whereas MDD is associated with volumetric enlargement. Reduced volume of the right medial nucleus mediates the relationship between CT and depression severity.

Objective:To understand the incidence of adverse pregnancy outcome in HIV-infected pregnant women and influencing factors in China and provide reference for the improvement of the health status of HIV-infected pregnant women and their newborns.Methods:Based on a mother-child cohort of HIV-infected pregnant women and children (PMTCT-MC-2005) established in Guangxi Zhuang Autonomous Region, Yunnan Province and Xinjiang Uygur Autonomous Region, this study enrolled pregnant women with or without HIV infection as study subjects from January 2017 to June 2023, a total of 1 646 pregnant women (558 HIV-infected and 1 088 HIV-uninfected) were included, and 34 cases with missing data were excluded. The χ2 test was used to analyze the difference in the incidence adverse pregnancy outcome between two groups, and used logistic regression model to identify the influencing factors of adverse pregnancy outcome in HIV-infected pregnant women. Results:A total of 1 612 pregnant women were included in the study, in whom 541 were infected with HIV and 1 071 were not infected with HIV. The incidence of adverse pregnancy outcome was 18.8% (303/1 612), the incidence of adverse pregnancy outcome was 33.1% (179/541) in the HIV-infected pregnant women and 11.6% (124/1 071) in the pregnant women without HIV infection. The results of multivariable logistic regression analysis showed that the influencing factors of adverse pregnancy outcome were age <35 years at delivery (a OR=0.64, 95% CI: 0.43-0.95) compared with the age ≥35 years and the duration of antiviral treatment over 10 years (a OR=0.43, 95% CI: 0.23-0.79) compared with less than one year. Conclusions:The incidence of adverse pregnancy outcome in HIV-infected pregnant women was high in some regions of China during 2017-2023. It is necessary for HIV-infected women to get pregnancy at appropriate time based on antiretroviral treatment effect and strengthen self-care to reduce the incidence of adverse pregnancy outcome.

Objective To systematically evaluate and integrate qualitative studies on perception of exercise behaviors in community-dwelling older adults with frailty,and to provide references for clinical development of targeted exercise intervention strategies.Methods A systematic search of PubMed,Medline,Embase,PsycINFO,the Cochrane Library,SinoMed,Wanfang Database,CNKI,and VIP Database for qualitative studies on perception of exercise behaviors in older adults with frailty in the community was conducted from the inception of the databases to June 2024.Literature quality was evaluated using the Australian Joanna Briggs Institute Centre for Evidence-Based Health Care Quality Assessment Criteria for Qualitative Research(2016 edition),and Meta-synthesis was performed using the theme synthesis method.Results A total of 10 papers were included,grouped into 10 categories and integrated into the 3 domains of the capability,opportunity,and motivation-behavior model(COM-B model),i.e.Preparation for exercise behavior is influenced by capability factors(physical reserve,knowledge reserve,psychological preparation);stage-specific motivational evolution promotes the internalization of exercise behavior(guiding,focusing,stimulating,and maintaining);external conditions provide opportunities for exercise behavior(individual interaction,community environment,and social support).Conclusion Perceptions of exercise behavior among community-dwelling older adults with frailty or are complex and influenced by a variety of factors.Future exercise intervention strategies should consider modifiable factors,enhance knowledge education,stimulate intrinsic motivation,and solidify external conditions,while also accommodating individual differences and preferences,so as to promote exercise participation and health enhancement in this group.

This paper presents a rare case of renal amyloidosis complicated with primary minimal change disease. The patient initially presented with edema and proteinuria, accompanied by IgG-λ monoclonal immunoglobulinemia, leading to a diagnosis of primary systemic immunoglobulin light chain amyloidosis with renal involvement. Following treatment, the patient achieved both hematologic and renal remission. However, a renal relapse occurred two years later, presenting as nephrotic syndrome without hematologic disease recurrence. A repeat renal biopsy revealed no obvious change in amyloid deposition, but demonstrated markedly enlarged effacement of podocyte foot processes. Based on these findings, a secondary diagnosis of primary minimal change disease was established. The patient exhibited a rapid response to immunosuppressive therapy, achieving sustained long-term remission. This case underscores the importance of remaining vigilant to etiological changes in the treatment of renal diseases and highlights the role of repeated renal biopsy in refining the diagnosis and guiding treatment.

The theory of "turbid pathogen harming the clarity" was proposed by YE Tianshi in his book Wenre Lun, which can be applied to clear orifices diseases such as ear, eye, nose, and mouth. Based on the location and characteristics of vitreous opacity, as well as its understanding by medical professionals throughout history, this article points out that the core pathogenesis of vitreous opacity is "turbid pathogen harming the clarity" and the obstruction of the spirit light, and the basic pathogenesis is: unfavorable liver and gallbladder conditions, damp heat accumulation and turbidity; imbalance of middle jiao, qi deficiency leading to turbidity; kidney failure with yang deficiency, stagnant water and fluids; and stagnation entering the collaterals for an extended time, causing blockage and turbidity. And based on the pathogenesis of "turbid pathogen harming the clarity" , corresponding treatment principles are proposed: soothing liver and promoting bile flow, clearing heat and eliminating turbidity; cultivating soil to produce gold, enhancing clarity and reducing turbidity; tonifying kidney and promoting yang, warming and dispelling turbid pathogens; and removing blood stasis and activating collaterals, dispelling turbidity and unblocking the orifices. Based on the theory of "turbid pathogen harming the clarity" , this article summarizes the pathogenesis and treatment of vitreous opacity, in order to provide new ideas for traditional Chinese medicine treatment of this disease.
