Objective To explore the application effect of a standardized management method based on failure mode and effect analysis （FMEA） in optimizing the whole-process quality control system of the intravenous admixture service （PIVAS）. Methods The quality control management system of the PIVAS was optimized by establishing six quality control groups led by the head nurse, with full participation of pharmacy, nursing, and logistical staff, ensuring comprehensive coverage and traceability of all quality control links. Each group conducted risk priority number （RPN） scoring for potential failure modes in their respective quality control processes, and targeted improvement measures were formulated based on the scoring results. The RPN values of failure modes and quality control-related evaluation indicators before and after implementation were compared to achieve closed-loop management. Results After one year of management, the RPN values of the six major failure modes significantly decreased compared to those before implementation （P<0.05）. The compounding error rate dropped to 0.13%, the dispensing error rate decreased to 0.95%, the compounding efficiency increased to 98%, the delivery time was shortened by 0.45 h per batch, the intervention rate for irrational prescriptions rose to 94.87%, satisfaction improved to 96.78%, and the participation rate of quality control personnel reached 95.36% （P<0.05）. Conclusion FMEA-based identification of potential failure modes in the whole-process quality control system of the IVAS, combined with risk quantification and targeted interventions, significantly reduced high-risk failure modes, improved compounding accuracy and efficiency, and ensured the safety of clinical intravenous medication and the effectiveness of healthcare quality management.

Objective:To explore the correlation between pulmonary emphysema and coronary artery calcification (CAC) in a health screening population.Methods:This retrospective case-control study consecutively selected 55 762 individuals who underwent chest low-dose chest CT (LDCT) screening at the Health Management Center of Southwest Hospital from January 2019 to December 2023. Demographic data, history of chronic diseases, anthropometric measurements, laboratory indicators, LDCT and pulmonary function test results were collected. Exclusion criteria included age<40 years at baseline, a history of coronary heart disease, LDCT suspected coronary artery stent placement, incomplete baseline data, and duplicate examinations. Logistic regression models were used to analyze the association between pulmonary emphysema and CAC.Results:A total of 33 069 individuals were included, with a mean age of 52 (47, 58) years old. Among them, 20 114 (60.8%) were male, 2 967 (9.0%) had pulmonary emphysema, and 4 156 (12.6%) had coronary artery calcification. The proportion of CAC in patients with emphysema was higher than in those without (23.5% vs 11.5%; χ2=351.805, P<0.001). After adjusting for confounding factors, the risk of CAC remained significantly higher in patients with emphysema [ OR=1.239 (95% CI: 1.113-1.379), P<0.001]. Conclusion:Pulmonary emphysema was one of the independent risk factors for coronary artery calcification in a health screening population.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Metanephric adenoma is a rare renal epithelial tumor with a low incidence and lack of specific clinical manifestations，resulting in a lack of uniformity in clinical understanding and treatment. Its etiology and pathogenesis are still unclear，and it may be related to the abnormal number and structure of chromosomes 2，7，and 17，as well as mutations in genes such as BRAF V600E，NF1，and NOTCH1，etc. There may be a transformed relationship between this tumor and Wilms’ tumor and papillary renal cell carcinoma. For diagnosis，it has diverse but non-specific clinical manifestations，and it is difficult to accurately differentiate it from other tumors in the imaging examination，and the confirmation of diagnosis relies on pathological and immunohistochemical staining. Treatment is mainly based on surgery to preserve the renal unit，such as partial nephrectomy，etc.，but the difficulty of preoperative diagnosis often leads to over-treatment，and there is a lack of standardized treatment protocols for metastatic posterior renal adenoma. The aim of this article is to provide a reference for the in-depth understanding of posterior renal adenomas and to optimize the clinical diagnosis and treatment strategies.

Background: SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood. Methods: We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival. Results: Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity. Conclusions The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.
