Objective:To explore the survival and prognostic factors of a long-course venetoclax-based(VEN-based)regimen in patients with de novo acute myeloid leukemia(AML)and provide evidence for the maintenance treatment of AML.Methods:A retrospective study was conducted in patients who received a VEN-based regimen and completed at least four courses of efficacy evaluation at The First Affiliated Hospital of Nanchang University from May 2021 to January 2024.The composite complete response rate(cCR),minimal residual disease(MRD)-negative rate,overall survival(OS)time,relapse-free survival(RFS)time,and adverse events were analyzed.Results:Overall,30 newly diagnosed patients with AML were enrolled in this study.The median age was 65(range,53-78)years,and the median number of treat-ment cycles was 7(range,4-20)years.After one cycle,the CR-and MRD-negative rates were 80.0%and 63.3%,respectively.The cumulative cCR was 96.7%,and MRD negative rate was 80.0%,respectively.The median follow-up time was 21.3(95%confidence intervals 14.7-27.9)months.The median OS time was 32.3 months and RFS time was not reached.The 2-year OS and RFS rates were 70.6%and 54.8%,respect-ively.Univariate analysis suggested that ELN2017 risk stratification and relapse status affected RFS and OS(P<0.05).However,the multivari-ate analysis failed to reveal any relationship between these factors and survival(P>0.05).In terms of safety,hematological adverse events were the most common,followed by infections.Overall,the VEN-based regimen was tolerated for patients with AML.Conclusions:A long-course VEN-based regimen is effective and safe.More than half of patients survive for>2 years,and it can be used as an effective mainten-ance treatment option for patients with AML.

ObjectiveTo explore the current situation of forensic ethics practice and education by designing a questionnaire on forensic ethics， with a view to exploring the path of forensic ethics education construction. MethodsA total of 667 valid questionnaires were collected using the online survey method， basically covering various regions across the country and all sub-specialties of forensic medicine. Descriptive analysis was used to analyze the relevant data. ResultsMost practitioners had relevant ethical reflections in the process of forensic practice. 69.12% of the respondents indicated that they had studied the relevant rules， but approximately half stated that there were no corresponding ethical norms or standard operating manuals. The specific behaviors violating ethics in different units were diverse. 23.04% of the respondents reported that they had encountered unethical behaviors， but only 4.9% of them reported such violations. In terms of forensic ethics education， 87.75% of the respondents believed that there were issues with the current model of forensic ethics education. Meanwhile， the respondents showed a high degree of recognition for receiving forensic ethics education， with 84.15% of respondents expressing willingness to participate in relevant courses. More than half of respondents were willing to participate in forensic ethics education during undergraduate studies， new employee training， and regular post-employment training. ConclusionCurrently， there is a problem of ethical neglect in forensic work in China. Combining ethics courses with professional courses at the practitioner training stage and providing regular training at the practice stage are effective measures to popularize forensic ethics knowledge， enhance ethical awareness， and improve the quality of practice.

Objective To investigate the geographical distribution patterns and influencing factors of suitable habitats for the desert medicinal plant Cynomorium songaricum Rupr under current climatic conditions;To provide a basis for its resource conservation and sustainable utilization.Methods The MaxEnt model was used to analyze potential suitable habitats for Cynomorium songaricum Rupr.Geographical Detector model was used to identify key environmental factors affecting habitat suitability.Surface cover data were overlaid to assess the distribution of sandy and Gobi regions within suitable habitats,enabling a quantitative evaluation of actual potential suitable areas.Results Model predictions indicated a total suitable habitat area of approximately 2.98×106 km2,representing 30.99%of China's mainland area.Highly suitable habitats are concentrated in desert and Gobi regions of Gansu,Xinjiang,Inner Mongolia,Qinghai and Ningxia.Among climatic factors,precipitation of the coldest quarter(bio19),solar radiation in August(srad8),and mean temperature of the coldest quarter(bio11)significantly influence Cynomorium songaricum Rupr distribution.The interaction between temperature and solar radiation intensity exhibited the highest explanatory power for habitat distribution patterns(q=0.82).Overlay analysis with surface cover data estimated the actual potential suitable area at approximately 9.70×105 km2,with sandy regions comprising 5.73×105 km2 and Gobi regions 3.98×105 km2.Conclusion By integrating multi-source data and modeling approaches,this study delineates the potential suitable habitats for Cynomorium songaricum Rupr across China and evaluates the spatial distribution characteristics and influencing factors of suitable habitats in Cynomorium songaricum Rupr.These findings offer a foundation for conserving wild Cynomorium songaricum Rupr resources,optimizing ecological planting regions,and promoting sustainable industry development.

BACKGROUND:The energy metabolism and polarization state of macrophages play a crucial role in the progression of atherosclerosis.Traditional Chinese Medicine(TCM)has shown significant therapeutic potential for prevention and treatment of atherosclerosis by regulating macrophage metabolic pathways.OBJECTIVE:To review the research progress in AMP-activated protein kinase regulation of macrophage energy metabolism and polarization and explore the mechanism of TCM in the prevention and treatment of atherosclerosis.METHODS:A computerized search was conducted on the databases including Web of Science,PubMed,and CNKI,covering relevant literature up to June 2024.The search terms were"AMPK,fatty acid oxidation,macrophage polarization,Traditional Chinese Medicine,atherosclerosis,coronary heart disease"in Chinese and English.A total of 62 articles were finally included for review.RESULTS AND CONCLUSION:The shiftin macrophage energy metabolism from oxidative phosphorylation to glycolysis plays a key role in the progression of atherosclerosis.The activation of AMP-activated protein kinase in macrophages promotes fatty acid oxidation and M2 polarization,exerting anti-inflammatory effects and stabilizing arterial plaques.TCM monomers(such as ginseng,astragalus,and polygonatum)and compounds(such as Huanglian Jiedu Decoction,Yangxin Shumai Granules,and Tiaogan Daozhuo Formula)influence macrophage metabolism and cellular function by regulating the AMP-activated protein kinase pathway and intervening in multiple signaling pathways,such as nuclear factor-κB,peroxisome proliferator-activated receptor γ,and mammalian target of rapamycin,thereby achieving therapeutic effects.Future research should focus on the interactions between AMP-activated protein kinase,metabolism,and polarization pathways,as well as how TCM exerts its therapeutic effects through these pathways,providing new strategies for the treatment of atherosclerosis.

Objective To explore the influence of early high-energy-density milk powder feeding on recovery and nutritional status in infants with congenital heart disease after surgery. Methods A total of 82 infants with congenital heart disease were selected and randomly divided into control group (early routine formula feeding) and study group (early high-energy-density formula feeding), with 41 cases in each group. The recovery outcomes, nutritional status, feeding conditions, and cardiac function were compared between the two groups. Results Mechanical ventilation time, treatment duration in Cardiac Intensive Care Unit (CICU), and hospital stay in the study group were significantly shorter than those in the control group (P < 0.05). Compared with preoperative levels, the levels of prealbumin (PA), retinol-binding protein (RBP), transferrin (TRF) and albumin (ALB) increased significantly in both groups at 3 months after operation (P < 0.05); at 3 months after operation, the levels of PA, RBP, TRF and ALB in the study group were significantly higher than those in the control group (P < 0.05). Compared with preoperative measurements, both groups showed significant improvements in height and body weight at 3 months after operation (P < 0.05); the height and body weight of the study group were significantly higher than those of the control group at 3 months after operation (P < 0.05). Compared with the control group, the study group had a significant lower rate of inadequate feeding and a significant higher rate of appropriate feeding (P < 0.05). Cardiac function of the study group was significantly better than that of the control group (P < 0.05). Conclusion Early high-energy-density milk powder feeding after congenital heart disease surgery in infants can promote faster recovery, improve nutritional status, and result in more appropriate feeding, with a lower incidence of heart failure.
