Despite breakthroughs in immunotherapy for solid tumors, significant variations in treatment efficacy persist. Up to 80% of cancer patients suffer from malnutrition, which leads to: lymphoid atrophy and reduced T-cell reserves; deficiency of substrates required for T-cell activation and expansion; concurrent inflammation hindering T-cell infiltration into tumors; and cachexia accelerating PD-1 antibody clearance. Clinical studies confirm that severe malnutrition significantly impairs immune responses and increases the risk of treatment toxicity. Therefore, implementing standardized nutritional therapy is crucial for optimizing the reserve, activation, expansion, and infiltration capacity of immune cells, thereby providing a sound immune system foundation for immunotherapy. Immunonutrition therapy, by enhancing immunonutrients such as arginine, omega-3 polyunsaturated fatty acids, and nucleotides, reduces the secretion of pro-inflammatory mediators and promotes T-cell activation and proliferation. This enhances anti-tumor immune responses, prolongs survival, and advances cancer treatment towards multimodal combination and precision approaches.

To assess the current status of early surgical site infections following prosthetic implantation in plastic surgery across four provincial-level administrative regions in China, and to explore the effectiveness of standardized training for infection prevention and control. From January to May 2025, an online questionnaire survey was conducted to perform a baseline investigation in medical institutions performing plastic and aesthetic prosthetic implant surgeries in Chongqing, Shaanxi, Jiangxi, and Guizhou provinces. Data were collected on the volume of various types of prosthetic implant surgeries and the corresponding incidence of early surgical site infections. Improvement strategies for the prevention and control of early surgical site infections in prosthetic implant surgeries were jointly developed by the National Medical Quality Control Center for Plastic and Aesthetic Surgery and the National Medical Quality Control Center for Hospital Infection Management, followed by promotion and training. Subsequently, post-implementation data from June to October 2025 were collected from the above regions, and comparisons were made between pre- and post-implementation periods across different regions and surgical categories. A total of 209 medical institutions were included in the baseline period, with a questionnaire response rate of 99.52% and a total of 7475 prosthetic implantation surgeries. In the post-implementation period, 624 medical institutions were included, with a response rate of 96.00% and a total of 4813 surgeries. The combined proportion of breast prosthesis implantation and nasal/nasal base prosthesis implantation surgeries consistently exceeded 80% across all regions and periods. Regarding the distribution of infection cases, among different types of prosthetic implant surgeries, nasal/nasal base prostheses accounted for the highest proportion, with 57.50%(23/40) at baseline and 62.86% 22/35) post-implementation. The proportion of breast prosthesis infections decreased from 40.00%(16/40) at baseline to 17.14%(6/35) post-implementation. Across different regions, infection cases in Jiangxi (post-implementation)(100%), Guizhou[both baseline(100%) and post-implementation(100%)] were all concentrated in nasal/nasal base prostheses. Shaanxi reported four cases of chin prosthesis infections (22.22%) during the post-implementation period, and Chongqing reported three cases of metal-related infections(27.27%) during the post-implementation period. In terms of infection rates, Chongqing(0.55% Breast prostheses and nasal/nasal base prostheses currently represent the main types of implants used in prosthetic implantation surgeries. The improvement strategies implemented in this study were associated with decreased early surgical site infection rates in multiple regions, suggesting that these strategies provide clinical insights for the prevention and control of early infections following prosthetic implantation surgeries in China.

Objective To investigate the registration rate and trend of pulmonary tuberculosis complicated with diabetes mellitus (PTB-DM) in Wuhan from 2020 to 2024, and to provide scientific evidence for formulating PTB-DM prevention and control policies. Methods PTB-DM case data in Wuhan (2020-2024) were collected through the Infectious Disease Registration and Management Information System. Joinpoint regression model was employed to analyze the trend of registration rates of PTB-DM among the general population and across different regions, genders, and age groups. ARIMA model was used to predict the short-term prevalence of PTB-DM. Results Among 26275 pulmonary tuberculosis cases registered in Wuhan (2020-2024), 2669 cases (10.16%) were PTB-DM. The average annual registration rate of PTB-DM was 3.96/100,000, increasing from 2.74/100,000 in 2020 to 5.40/100,000 in 2024 (APC=19.07%, 95% CI:12.99%-26.92%, P<0.001). The PTB-DM registration rates showed an upward trend across different regions, genders, and age groups in Wuhan, with higher registration rates observed in near urban area, males, and individuals aged 60~64 and 65 years and above (χ2=99.566, P<0.001; χ2=781.891, P<0.001; χ2=2211.930, P<0.001). ARIMA model predicted that the prevalence of PTB-DM in Wuhan would remain stable and fluctuating in the short time. Conclusion PTB-DM registration rate in Wuhan increases from 2020 to 2024. Near urban area, males, and elderly populations are high risk groups. Future efforts should focus on strengthening the prevention and control of PTB-DM among these populations.

ObjectiveTo systematically retrieve, analyze, and summarize the basic information and clinical research evidence of Chinese patent medicines (CPMs) for endometriosis via a scoping review method. MethodsCPMs indicated for EM were identified from three major drug lists, CNKI, clinical guidelines, and textbooks. Relevant clinical studies were retrieved from eight Chinese and English databases from inception to April 1, 2025. Key data from included studies were extracted to analyze characteristics of CPMs and their clinical evidence. ResultsA total of 18 CPMs were included, among which those with blood-activating and stasis-resolving effects accounted for the highest proportion. Constituent herbs predominantly exhibited sweet, bitter, and pungent flavors, with tropism to the liver and spleen meridians. Daily treatment costs varied substantially across CPMs. The 438 included studies involved 13 CPMs, among which Guizhi Fuling capsules/pills, Sanjie Zhentong capsules, and Dan'e Fukang soft extract/granules were the most extensively studied. Randomized controlled trials (RCTs) were the predominant study design. The most common comparison was between CPMs combined with Western medicine and Western medicine alone. The largest number of studies reported a sample size of 51-100 cases. The high-frequency outcome indicators covered 10 domains, including clinical response rate, adverse reactions, female hormone levels, serum CA125 levels, and recurrence status. ConclusionMultiple oral CPMs demonstrate efficacy in EM management, yet inadequate safety profiles persist in drug labeling. The annual number of clinical studies on oral CPMs for endometriosis showed an overall increasing trend. However, clinical research has shortcomings including uneven distribution of CPMs, small sample sizes, and suboptimal methodological rigor. Future efforts should focus on updating drug indications and safety information in package inserts, conducting high-quality clinical research, and generating more robust evidence to support the clinical use of oral CPMs for EM.

ObjectiveTo enhance the genetic diagnostic yield for fetal short femur length (FL) and to evaluate the integration of whole exome sequencing (WES) with chromosomal abnormality detection in prenatal diagnosis. MethodsA total of 27 mid-to-late trimester fetuses diagnosed with short FL [FL < 5th percentile for gestational age or < -2 SD (Standard Deviation)] at the Prenatal Diagnosis And Medical Genetics Center,Shenshan Medical Center,Memorial Hospital of Sun Yat-Sen University between November 2023 and May 2025 were included. Amniotic fluid or umbilical cord blood samples were collected and subjected to chromosomal karyotyping (19cases), chromosomal microarray analysis (CMA) or low-coverage whole genome copy number variation(CNV-Seq) (27 cases), and trio-based whole exome sequencing (trio-WES) (27 cases). The pathogenicity of genetic variants were interpreted according to the American College of Medical Genetics and Genomics (ACMG) guidelines. ResultsTwenty-six genomic variants were detected in 17 of the 26 fetuses, including numerical chromosomal abnormalities (mosaic type), copy number variations (CNVs), single nucleotide variants (SNVs) and insertions-deletions (INDELs). Genomic variants detected in 11 cases could explain the short femur phenotype.The overall diagnostic rate was 11/27, with pathogenic/likely pathogenic variants explaining 9 cases and variants of uncertain significance (VUS) accounting for 1 cases. In addition Chromosomal karyotype analysis revealed chromosome mosaicism explaining 1 case. The diagnostic rate of CNV detection (CMA/CNV-seq) was 2/27, while WES achieved a diagnostic rate of 10/27, with an incremental yield of 8/27 in cases with negative or inconclusive CNV results. Pathogenic mutations involved genes such as FGFR3, SHOX, DUOX2, CLCN5, and HBA1/HBA2. ConclusionTrio-WES significantly improves the genetic diagnostic rate for fetal short femur length, particularly in cases where chromosomal analysis fails to identify a cause. Karyotyping remains valuable for detecting low-level mosaicism in large-scale chromosomal abnormalities, thereby complementing WES and CNV detection. A stepwise or parallel genetic testing strategy is recommended in prenatal diagnosis to optimize diagnostic efficiency and support clinical decision-making.

Objective:To investigate the relationship between the changes in extracellular vesicles (EVs) size distribution before and after cardiopulmonary bypass (CPB) cardiac surgery and postoperative coagulation function.Methods:A total of 103 patients undergoing cardiac surgery with CPB were enrolled. Venous blood samples were collected at preoperation, postoperative 12 h and 3 days. Additionally, 50 age- and gender-matched healthy volunteers served as a control group. EVs were isolated using gradient centrifugation, and their size distribution was assessed by dynamic light scattering (DLS). The relationship between EV size characteristics, including peak diameter, peak height, and interquartile range( IQR), and postoperative coagulation function was analyzed. Results:Compared to patients with normal postoperative coagulation function, those with postoperative coagulation dysfunction had lower size at peak and IQR, and significantly higher peak intensity. Logistic regression analysis indicated that elevated peak intensity and lower size at peak and IQR were risk factors for coagulation dysfunction. The area under the curve ( AUC) for diagnosing coagulation dysfunction with 12 h postoperative EVs peak intensity was 0.76, with a positive predictive value of 85% at the optimal cutoff of 8.2; the AUC for IQR was 0.84, with a sensitivity of 83%, specificity of 82%, and negative predictive value of 86% at the optimal cutoff of 125.05 nm. Conclusion:The size distribution of circulating EVs show a correlation with coagulation function after cardiac surgery with CPB and may serve as a novel biomarker to predict postoperative coagulation dysfunction.

Background and Aims:Pancreatic cancer is a highly malignant digestive system tumor characterized by poor prognosis and limited therapeutic response.The tumor microenvironment plays a crucial role in its progression,where oxidative stress and lactate metabolism are two tightly interconnected processes influencing tumor growth,immune escape,and therapeutic resistance.However,their combined prognostic impact remains poorly understood.This study aimed to integrate oxidative stress-and lactate metabolism-related genes to establish and validate a robust prognostic model for pancreatic cancer,and to explore its association with immune microenvironment characteristics.Methods:Transcriptomic and clinical data of 177 pancreatic cancer patients were obtained from TCGA database and an external validation was performed using the GEO dataset(GSE57495).Differentially expressed genes associated with oxidative stress and lactate metabolism were identified using the"limma"package.Univariate Cox regression was used to screen prognostic genes,followed by LASSO regression to construct a multi-gene risk model.Model performance was evaluated by Kaplan-Meier survival analysis,receiver operating characteristic(ROC)curves,concordance index(C-index),nomogram calibration,and decision curve analysis(DCA).The CIBERSORT and ssGSEA algorithms were used to analyze immune cell infiltration and immune functional differences between risk groups.Results:A six-gene signature(MUC1,KRT18,SDC1,AREG,DDC,and ATPAF2)was identified to construct the prognostic model.Based on the calculated risk score,patients were stratified into high-and low-risk groups.Kaplan-Meier analysis revealed significantly worse overall survival in the high-risk group(P<0.01).The model showed good predictive accuracy with 1-,2-,and 3-year AUCs of 0.710,0.674,and 0.649,respectively.The C-index and calibration curves confirmed its reliability,and multivariate Cox regression indicated that the risk score was an independent prognostic factor.External validation using GEO data demonstrated consistent predictive performance.Immune infiltration analysis revealed that M0 macrophages were markedly enriched in the high-risk group,while cytotoxic and effector T-cell populations were reduced,suggesting that an immunosuppressive microenvironment may contribute to poor outcomes.Conclusion:This study developed and validated a novel prognostic model for pancreatic cancer based on oxidative stress and lactate metabolism-related genes.The model accurately predicts patient survival,reflects immune microenvironment heterogeneity,and provides new molecular insights for risk stratification and individualized therapeutic strategies in pancreatic cancer management.
