Objective To analyze survival outcomes and influencing factors among patients with colorectal cancer in Yunnan Province. Methods Clinical data were retrospectively collected from 4 892 patients with colorectal cancer. Survival data were obtained through follow-up. Overall survival (OS) was calculated by using the Kaplan-Meier method. Univariate analysis was performed by applying the log-rank test. Meanwhile, multivariate analysis employed the Cox proportional hazards regression model. Results The 1-, 3-, 5-, and 10-year OS rates for the entire cohort were 91.90%, 74.40%, 64.40%, and 28.70%, respectively. Univariate analysis revealed that age, ethnicity, region, differentiation grade, TNM stage, clinical stage, metastatic status, histological type, and treatment modality (chemotherapy, radiotherapy, and surgery) were associated with patient prognosis (all P<0.05). Multivariate analysis identified age (HR=1.250), region (HR=1.262), differentiation grade (HR=0.761), clinical stage (HR=3.128), and treatment modality (chemotherapy, HR=0.644; radiotherapy, HR=1.605; surgery, HR=0.384) as independent factors affecting survival prognosis in patients with colorectal cancer (all P<0.001). Conclusion Age, region, clinical stage, and treatment modality are independent factors influencing survival among patients with colorectal cancer in Yunnan Province. In clinical practice, these factors should be integrated to develop individualized prevention and treatment strategies, thereby improving patient outcomes.

Objective:To summarize the best evidence for nutrition management of sarcopenia in patients undergoing maintenance hemodialysis (MHD), to guide the development of nutrition management programs.Methods:Using the 6S evidence model, literature on nutrition management of sarcopenia in MHD patients was electronically retrieved from databases and websites including UpToDate, Guidelines International Network, Joanna Briggs Institute Evidence-Based Health Care Center Database, European Society for Clinical Nutrition and Metabolism, UK Kidney Association, PubMed, Web of Science, China Biology Medicine disc, China National Knowledge Infrastructure, and Wanfang Data. The search period was from database establishment to July 30, 2024. After screening and quality assessment of the literature, evidence was extracted and summarized.Results:A total of 19 articles were included, comprising one clinical decision, six guidelines, five systematic reviews, five expert consensus, and two randomized controlled trials. Twenty-six pieces of evidence were summarized from six aspects of nutrition team establishment and counseling, nutritional screening and assessment, nutritional support, nutrient intake, nutritional monitoring, and health education.Conclusions:The evidence summary on nutrition management of sarcopenia in MHD patients provides a basis for implementing nutritional interventions. Evidence transformation and application should be conducted in accordance with patient preferences and the actual clinical context.

Anhedonia is one of the core features of major depressive disorder (MDD) and is associated with poor functional outcomes in MDD patients. Psychosocial functional recovery is an important goal for achieving MDD remission. Although longitudinal studies have found association between anhedonia and impaired psychosocial function, there is still a lack of neurobiological biomarkers that can indicate this relationship. In this review, brain structural and functional changes associated with anhedonia and impaired psychosocial function in MDD patients are reviewed from the perspective of magnetic resonance imaging. It finds that anhedonia and psychosocial dysfunction in MDD may share common neuroimaging changes, manifested in abnormal brain regions such as the nucleus accumbens, caudate nucleus, putamen nucleus, orbitofrontal cortex, insula, amygdala, anterior cingulate cortex, dorsolateral prefrontal cortex, superior parietal lobe, inferior frontal gyrus and temporal lobe. These findings help to better understand the pathophysiology of the disease and offer potential insights for developing new treatment strategies.

Objective The efficacy of Zang Bi Formula(ZBF)in cardiac complications of rheumatoid arthritis(RA)was observed through animal experiments.Ultra-high performance liquid chromatography tandem time-of-flight mass spectrometry(UHPLC-TOF-MS)and network pharmacology was used to analyze the active ingredients,targets,and pathways of ZBF for the treatment of cardiac hypertrophy,and molecular docking was applied to verify the binding ability of the ingredients to pathway-related proteins.Methods TNF transgenic(TNF-Tg)mice were used as RA and RA-complexed cardiac hypertrophy models,and the left ventricular hypertrophy of mice was observed by echocardiography after 8 weeks of continuous gavage with ZBF,and WGA staining,HE staining,and Masson staining were used to observe and analyze the pathological changes of cardiac tissues.The chemical composition of ZBF was identified by UHPLC-TOF-MS technique.The public database was then used to screen the active ingredients and component targets and disease targets,construct interaction networks,and analyze the bioconcentration data as well as the docking ability of the active ingredients and proteins.Results In animal experiments,ZBF reduced cardiac weight index and cardiac weight tibia length ratio in TNF-Tg mice(P＜0.05,P＜0.01),attenuated cardiac hypertrophy(P＜0.001)and cardiomyocyte hypertrophy(P＜0.01),and alleviated inflammatory infiltration and fibrosis in the heart(P＜0.0001).A total of 24 compounds were identified from ZBF by UHPLC-TOF-MS.A total of 105 active ingredients of ZBF were screened by network pharmacological analysis,and 187 potential targets of ZBF for cardiac hypertrophy were constructed,and the enriched pathways with significance included PI3K-AKT signaling pathway,TNF signaling pathway,and MAPK signaling pathway.Conclusion ZBF attenuated myocardial hypertrophy and cardiomyocyte hypertrophy in TNF-Tg mice and alleviated inflammatory infiltration and fibrosis in the heart,and ZBF may be a potential drug for the treatment of RA and its cardiac complications in the clinic.

Neurocognitive dysfunction has been identified in major depressive disorder (MDD), and can potentially impair an individual′s psychosocial functioning. Consequently, the relationship between neurocognition and psychosocial functioning of MDD has gradually become one of the hot spots in recent years. Studying the association can help explore the biological basis of psychosocial functioning in depression, allows for underpinnings, targeted clinical interventions, and ultimately achieves true rehabilitation. This article summarises studies on the specific relationships between subfields of neurocognitive and psychosocial function in MDD, and discusses potential future research directions.
