Medical ethics aims to address moral issues in medical practice. When analyzing the right and wrong in medicine， it emphatically interprets “what medicine ought to be” and focuses on how physicians should act correctly. Hence， highly directive ethical theories such as deontology and utilitarianism have become the fundamental theories for medical decision-making. Nevertheless， as the concentrated embodiment of medical ethical values， virtue ethics also constitutes an important component of medical ethics. Drawing on Julia Annas’s creative development of virtue ethics theories regarding “right action” and “right emotion，” which is based on the distinction between “virtue learners” and “virtue possessors，” this paper provides a new theoretical perspective and practical approach for bridging the divide between heteronomy and autonomy in medical ethics， enhancing the care for medical staff’s emotions in medical ethics education， and promoting mutual understanding and communication between physicians and patients.

OBJECTIVE To systematically review medication-related risk factors for falls in older adults， to provide references for ensuring medication safety among older adults. METHODS A systematic search was conducted in PubMed， Embase， Web of Science， and CNKI for relevant literature published from database inception to November 1， 2025. Relevant studies on medication-related falls in older adults， both domestic and international， were included. Drug factors influencing falls in older adults were summarized and analyzed. RESULTS A total of 22 studies were included. Four major classes of fall-risk-increasing drugs were identified： psychotropic medications [12 studies， odds ratio （OR） range 1.500-5.790]， cardiovascular system drugs （5 studies， OR range 1.236-4.784）， analgesics （3 studies， OR range 1.500-4.490）， and hypoglycemic agents （3 studies， OR range 2.070-2.751）. Additionally， anticholinergic burden （1 study， OR was 2.610） and polypharmacy （7 studies， OR range 2.902-25.897 for the use of ≥4 medications） were identified as significant risk factors for falls. CONCLUSIONS Falls in older adults are significantly associated with psychotropic medications， cardiovascular system drugs， analgesics， and hypoglycemic agents， among which psychotropic medications pose the highest risk. Anticholinergic burden and polypharmacy are also important risk factors. In clinical practice， interventions should be implemented through deprescribing and risk monitoring to effectively reduce the risk of falls in older adults.

Inflammation is the body’s response to damage， infection or other stimuli， but its excessive or continuous development can lead to a variety of diseases. Although modern medical anti-inflammatory therapies were widely used， it is often accompanied by limitations such as more adverse reactions. Based on the “holistic view” and “differential treatment”， traditional Chinese medicine （TCM） regards inflammation as a manifestation of the imbalance of yin and yang in the body and the conflict between good and evil. The application of anti-inflammatory TCM is not only aimed at the pathological state of “inflammation”， but also based on the overall consideration of “syndrome”. According to different types of syndrome， anti-inflammatory TCM can be divided into heat-clearing and detoxifying agents （such as Lonicera japonica and Isatis indigotica ）， heat-clearing and drying dampness agents （such as Coptidis Rhizoma）， blood-activating and stasis-dissolving agents （such as Salvia miltiorrhiza ） and vital qi-strengthening and pathogenic factor-expelling agents （such as Panax ginseng ）. Four types of anti-inflammatory TCM restore the body’s immune balance through the systematic regulation of multi-component， multi-target and multi-pathway， exhibiting a good anti-inflammatory effect. Future research should focus on integrating systematic biology， applying artificial intelligence， carrying out high-quality evidence-based research， and combining traditional Chinese medicine and Western medicine， so as to reveal the overall regulatory law of anti-inf lammatory effects of TCM and promote clinical rational use.

Intrahepatic cholangiocarcinoma (ICC) is a highly malignant primary tumor originating from the intrahepatic bile duct epithelium. Current clinical consensus emphasizes that early detection,timely diagnosis,and R0 resection (when feasible) are critical strategies for improving outcomes. Advances in surgical techniques and multidisciplinary approaches have facilitated precision medicine-guided systemic therapies,including adjuvant and neoadjuvant regimens. These interventions significantly delay postoperative recurrence and improve 5-year survival rates. Systemic treatments have also modestly enhanced prognoses for advanced ICC patients. Artificial intelligence-driven radiomics and deep learning technologies show substantial efficacy in ICC diagnosis,prognostic assessment,and lymph node metastasis prediction,advancing precision medicine applications. Despite these therapeutic advances,survival outcomes-particularly for advanced-stage ICC-remain suboptimal. Future efforts should prioritize molecular signature-guided therapies,novel combination regimens,and artificial intelligence-assisted comprehensive management to establish a molecularly driven precision treatment framework.

To explore the protective effect of Angelica sinensis polysaccharide(ASP)on leptospiro-sis induced by pathogenic Leptospira infection,the golden hamster model of leptospirosis was se-lected for the experiment.The Leptospira and Leptospira+ASP groups were intraperitoneally injected with Leptospira interrogans serovar Lai strain 56601(1 × 10 6 per hamster).After infec-tion,the Leptospira+ASP group was injected intraperitoneally with ASP(50 mg/kg)for three consecutive days,while the Leptospira group was injected intraperitoneally with normal saline for three days.The experiment employed methods such as daily observation of the clinical symptoms of golden hamsters,statistics of the survival status of each group of golden hamsters,pathological damage of liver,kidney,and lung,bacterial load in organs,and the expression of inflammatory cy-tokines(IL-1β and TNF-α).The results indicated that ASP could effectively alleviate the clinical symptoms of the infected hamsters,enhance the survival rate,ameliorate the pathological damage of the body,reduce the bacterial load in various organs,and mitigate tissue inflammation.This study demonstrated for the first time that ASP has a protective effect on leptospirosis,providing medication guidance for the clinical treatment of leptospirosis.

Objective To compare the clinical efficacy of different urinary diversions,specifically exploring whether the flap embedding technique can improve bladder cancer patients'quality of life and reduce the incidence of related complications.Methods 63 bladder cancer patients undergoing radical cystectomy with urinary diver-sion,between December 2022 and December 2023,were divided into three groups:Ileal conduit group(n=21),flap embedding technique group(n=21),and traditional cutaneous ureterostomy group(n=21).General clini-cal data,surgical data,preoperative and postoperative renal function indicators,incidence of complications within 6 months postoperatively,and quality of life scores were compared among the groups.Results The operative time in the ileal conduit group was longer than that in the other two groups(P<0.05).The quality of life scores in the flap embedding technique group were superior to those in the traditional cutaneous ureterostomy group(P<0.05),but no significant difference was found compared to the ileal conduit group(P>0.05).In terms of postoperative complications,the incidence of intestinal obstruction in the flap embedding technique group was lower than that in the ileal conduit group(P<0.05),and the rate of reinsertion of a single-J stent for hydronephrosis in the flap embedding technique group was lower than that in the traditional cutaneous ureterostomy group(P<0.05).Postop-erative serum creatinine levels in the traditional cutaneous ureterostomy group were significantly higher than preop-erative levels(P<0.05),while no significant differences in renal function indicators were observed in the other two groups(P>0.05).Conclusion The flap embedding technique significantly improves patients'quality of life and reduces the incidence of postoperative complications.It is worthy of further promotion in clinical practice.

Objective:The association between air pollutants and the risk of sudden cardiac death (SCD) remains controversial. This study aimed to investigate the relationship between five air pollutants—PM 2.5, PM 2.5–10, PM 10, NO 2, and NO?—and the risk of SCD. Methods:We analyzed data from 460 862 participants in the UK Biobank cohort, all enrolled between 2006 and 2010, with no baseline SCD. Follow-up continued until the study endpoint. Annual average concentrations of the five pollutants were assessed. Associations between pollutants and SCD were evaluated using Cox proportional hazards models, followed by Mendelian randomization (MR) to assess causality.Results:Over a mean follow-up of 12.4 years, 2 662 SCD cases were recorded. After adjusting for confounders, no significant associations were found between air pollutants and SCD risk: PM 2.5 ( HR 1.03, 95% CI 0.99–1.07, P = 0.14), PM 2.5–10 ( HR 1.04, 95% CI 1.00–1.08, P = 0.08), PM 10 ( HR 1.01, 95% CI 0.99–1.03, P = 0.26), NO? ( HR 1.00, 95% CI 0.99–1.00, P = 0.26), and NO x ( HR 1.00, 95% CI 1.00–1.01, P = 0.19). MR analysis further supported the absence of causal relationships: PM 2.5 ( β = -0.149, P = 0.90), PM 2.5–10 ( β = 0.387, P = 0.62), PM 10 ( β = -0.994, P = 0.62), NO? ( β = –0.005, P = 0.99), and NO 2 ( β = –0.827, P = 0.25). Conclusions:This study found no evidence linking PM 2.5, PM 2.5–10, PM 10, NO?, or NO 2 to an increased risk of SCD. Mendelian randomization confirmed the lack of causal associations between these pollutants and SCD.

Objective:Acute myocardial infarction (AMI) secondary to acute gastrointestinal bleeding (AGIB) is a common severe condition in emergency department. Currently, there is a lack of sufficient data regarding the use of emergency endoscopy in patients suffering from acute gastrointestinal bleeding (AGIB) complicated with acute myocardial infarction (AMI). The objective of this study is to examine the present status, effectiveness, and safety of emergency endoscopy in such patients, and to determine the factors that influence clinicians' decision-making regarding the use of emergency endoscopy.Methods:Clinical data of AGIB patients complicated with AMI who were admitted to the emergency department of the First Affiliated Hospital of Nanjing Medical University from January 2020 to June 2023 were respectively collected. Based on their survival status at discharge, patients were categorized into survival and non-survival groups. Additionally, according to whether emergency endoscopy was performed, patients were further classified into the emergency endoscopy group and the conventional treatment groupStabilized inverse probability of treatment weighting (SIPTW) and logistic regression analysis were used to explore the correlation between emergency endoscopy and prognosis. A paired wilcoxon test was used to analyze whether emergency endoscopy could worsen myocardial injury. A multiple logistic regression model was used to explore the factors influencing clinicians to make emergency endoscopic decisions.Results:A total of 106 patients with AMI secondary to AGIB were included, and 22 patients underwent emergency endoscopy. After weighing, logistic regression analysis showed that emergency endoscopy was a protective factor for patients' survival after discharge ( OR = 0.808, 95% CI: 0.6755-0.967, P = 0.022). In the emergency endoscopy group, there was no significant change in hypersensitive troponin T before and after emergency endoscopy [ 61.1 (35.4, 164.1) ng/L vs 69.8 (60.1, 159.5) ng/L, P = 0.078]. Previous history of coronary heart disease ( OR = 0.098, 95% CI: 0.015-0.381, P = 0.003) was an independent negative factor for emergency endoscopic decision-making. Glasgow Blatchford Score (GBS) on admission ( OR = 1.217, 95% CI: 1.019-1.482, P = 0.038) was an independent positive factor for emergency endoscopic decision-making. Conclusions:Emergency endoscopy is safe and effective in patients with AMI secondary to AGIB. GBS score and previous history of coronary heart disease were the main factors affecting emergency endoscopic decision-making.

Objective:To summarize the experience and effect of extracorporeal cardiopulmonary resuscitation (ECPR) in acute myocardial infarction (AMI) with in-hospital cardiac arrest (IHCA).Methods:The data of 70 patients with AMI-IHCA-ECPR in extracorporeal life support center of the first affiliated hospital of Nanjing medical university from January 2017 to December 2024 were retrospectively analyzed. The patients were grouped by Survival/death at 90 days, with/without combined intra-aortic balloon pump (IABP). Age, sex, Charlson comorbidity index, initial rhythm, Gensini score, ECPR initial blood gas pH and lactate value, no-flow time, time from cardiac arrest to extracorporeal membrane oxygenation (ECMO) initiation (CA-Pump On time), ECMO treatment time, 90-day survival rate were analyzed.Results:Among the 70 patients with AMI-IHCA-ECPR, 22 (31.4%) patients survived at 90 days, of whom 19 (86.4%) patients had good neurological outcomes. About 50% of AMI-IHCA-ECPR patients had severe multi-vessel coronary artery lesions, and there was no significant difference in survival outcomes among different vascular lesions. In the IABP group, the success rate of ECMO withdrawal was low, the duration of ECMO treatment was long, and the combination of IABP did not reduce the mortality. Compared with the death group, the 90-day survival group had a lower Gensini score, a higher ECPR initial blood gas pH and a lower lactic acid value.Conclusions:AMI-IHCA-ECPR combined with IABP did not show significant survival benefits, and about 50% of patients had severe lesions of multiple coronary arteries. It is difficult to evaluate the prognosis based on a single offender vessel. It is recommended to evaluate the outcome of patients by quantification of the severity of coronary artery lesions by Gensini score.
