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.

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.

Objective:To explore the effectiveness of find-organize-clarify-understand- select-plan-do-check-act (FOCUS-PDCA) cycle management in improving the accuracy of Nutritional Risk Screening 2002 (NRS 2002) scoring in inpatients.Methods:This study was a retrospective study. Data from a continuous quality improvement project, namely Improving the Accuracy of Nutritional Risk Screening for Inpatients from People's Hospital of Longhua in 2021 were selected. The NRS 2002 scores of newly admitted patients from 8 departments with relatively high nutritional risk (departments of gstroenterology, neurology, nephrology, respiratory medicine, oncology and hematology, neurosurgery, gastrointestinal surgery, and critical care medicine) from April 10, 2021 to April 29, 2021 (before intervention) were collected. The NRS 2002 scores were evaluated by a multidisciplinary nutrition support team in terms of accuracy and error types. Possible issues in the process of nutritional screening were analyzed and mitigated using the FOCUS-PDCA cycle management method. The NRS 2002 scores from July 18, 2021 to August 8, 2021 (after intervention) were collected in real time to summary the data on accuracy and error types and to evaluate the effect of FOCUS-PDCA.Results:The accuracy of NRS 2002 score in the 8 departments was increased from 52.97% (294/555) to 81.13% (473/583) after intervention, and the difference was statistically significant ( χ2=102.606, P<0.001). The accuracy of nutritional status impairment score was 64.14% before intervention, compared with 90.57% after intervention ( χ2=114.484, P<0.001). The accuracy of disease severity score was 78.56%, compared with 89.54% after intervention( χ2=25.736, P<0.001). The false-negative rate was 68.02% before intervention and 31.87% after intervention, and the difference was statistically significant ( χ2=31.501, P<0.001). Conclusion:FOCUS-PDCA can improve the accuracy of NRS 2002 scoring in inpatients, reduce the risk of failing to identify patients at nutritional risk, and contribute to further nutritional diagnosis and treatment.

Objective:To address the critical issue of missing dynamic border molding information in edentulous direct digital impression technology, this study explores innovative digital solutions and conducts preliminary application validation.Methods:Based on the myostatic line theory, a methodology was established: intraoral scanner (IOS) high-frequency video was utilized to dynamically capture functional molding data of soft tissues, integrated with a self-developed mobility gradient recognition algorithm to achieve dynamic threshold segmentation between the muscle dynamic zone and myostatic zone, termed "optical digital molding technology". Ten edentulous patients with well-fitting complete dentures, treated at the Department of Prosthodontics, Peking University School and Hospital of Stomatology from January 2024 to December 2024, were enrolled. The standard deviation between the muscle static line (generated by mobility gradient algorithm with thresholds of 0.3-0.7 mm) and the denture border curve was analyzed to optimize the dynamic threshold, followed by single-case clinical validation.Results:Among the mobility thresholds of 0.3-0.7 mm, the 0.5 mm threshold yielded the smallest standard deviation between the myostatic line and denture border. Clinical validation demonstrated that dentures designed with this threshold exhibited no displacement during dynamic functional tests, with marginal sealing meeting clinical standards.Conclusions:The optical digital border molding technique for edentulous soft tissue boundaries translates the myostatic line theory into quantifiable parameters for the first time. Based on data from 10 cases, a mobility threshold of 0.5 mm is recommended for clinical application.

Objective:To explore the application and clinical significance of pathological diagnostic criteria for medically refractory epilepsy in children.Methods:Cross-sectional study.A retrospective analysis was conducted on 490 children(pathology involved) with medically refractory epilepsy treated continuously in the Pediatric Epilepsy Center of Peking University First Hospital from January 2019 to May 2022.The distribution of different pathological types was observed, and the differences in clinical characteristics among different pathological types were analyzed through Kruskal-Wallis or χ2 tests.The impact of clinical and pathological features on patient prognosis was evaluated through regression analysis. Results:Focal cortical dysplasia (FCD) was the predominant lesion (49.59%, 243/490).The electroencephalograms ( χ2=6.720, P=0.035) and clinical seizure characteristics ( χ2=26.370, P<0.001) in FCDⅡ were more focal than those in FCD Ⅰ and Ⅲ.Moreover, the proportions of focal resection in surgery ( χ2=24.286, P<0.001) and central involvement ( χ2=22.849, P<0.001) in FCDⅡ were higher than those in FCD Ⅰ and Ⅲ.Univariate and multivariate regression analyses revealed that FCD Ⅱ had a better prognosis than other dysplastic patients among the 375 cases of dysplasia ( P=0.049).Next-generation sequencing was performed on 35 cases of cortical malformations with such morphological characteristics as increased numbers of neurons in the white matter and Olig2-positive glial cell hyperplasia, and SLC35A2 mutations were detected in 2 cases (5.71%). Conclusions:Pathology of refractory epilepsy is specialized and continuously evolving.Standardized specimen processing and the accumulation of morphological, immunohistochemical, and molecular genetic data provide the foundation for clarifying the neuropathological nature of epilepsy, improving integrated classification, and advancing prognosis prediction and targeted therapy.

Objective To investigate the effects of long non coding RNA MAGI2 antisense chain RNA3(LncRNA MAGI2-AS3)on the migration,invasion,and epithelial mesenchymal transition(EMT)of gastric cancer(GCa)cells by regulating the miR-194-5 p/caveolin-1(CAV1)axis.Methods Fifty-two GCa patients who underwent surgical resection in our hospital from August 2022 to December 2023 were selected.Cancer and adjacent tissues were collected,and AGS,MKN45,HGC-27,and GES1 cells were cultured in vitro.The expression of MAGI2-AS3,miR-194-5p,and CAV1 in tissue samples and cell lines was analyzed.AGS cells were randomly separated into AGS group,sh-AGS group sh-MAGI2-AS3 group,miR-NC group,and in miR-194-5p group.The proliferation,apoptosis,migration,and invasion of cells in each group were compared.Immunoblotting was applied to analyze the expression of E-cadherin,CAV1,proliferating cell nuclear antigen(PCNA),N-cadherin,Bax,matrix metalloproteinase 2(MMP2),and vimentin of cells in each group.Dual luciferase assay was applied to analyze the relationship between MAGI2-AS3 and miR-194-5p,and between miR-194-5p and CAV1.Results The expression of MAGI2-AS3 mRNA,CAV1 mRNA,and positive expression rate of CAV1 protein in GCa tissue increased,while the expression of miR-194-5p mRNA decreased(P＜0.05).The expression of MAGI2-AS3 mRNA,CAV1 mRNA,and CAV1 protein in HGC-27,MKN45,and AGS cells was higher than that of GES1 cells,the expression of miR-194-5p mRNA was lower than that of GES1 cells(P＜0.05).Compared with the AGS and sh-AGS groups,the cell absorbance,number of clones,invasion and migration,expression of CAV1,PCNA,N-cadherin,MMP2,and vimentin in sh-MAGI2-AS3 group decreased,the apoptosis rate,expression of E-cadherin,and Bax increased(P＜0.05).Compared with the miR-NC group and sh-MAGI2-AS3 group,the cell absorbance,number of clones,invasion and migration,expression of CAV1,PCNA,N-cadherin,MMP2,and vimentin in in-miR-194-5p group increased,the apoptosis rate,expression of E-cadherin,and Bax reduced(P＜0.05).ENCORI database found that there were multiple binding sites between MAGI2-AS3 and miR-194-5p,and between miR-194-5p and CAV1.Compared with the WT-MAGI2-AS3+miR-NC group,the luciferase activity in the WT-MAGI2-AS3+miR-194-5p group decreased(P＜0.05),while compared with the WT-CAV1+miR-NC group,the luciferase activity in the WT-CAV1+miR-194-5p group decreased(P＜0.05).Conclusion LncRNA MAGI2-AS3 silencing can target miR-194-5p to downregulate CAV1,thereby inhibiting GCa cell migration,invasion,and EMT.

Objective We aimed to evaluate the efficacy and safety of Shengxuebao Mixture in the treatment of cancer-related anemia(CRA)presenting with syndrome of deficiency of liver and kidney combined with syndrome of deficiency of both qi and blood.Methods A randomized,double-blind,placebo-controlled,multicenter clinical trial was conducted.Eligible patients with malignant tumors meeting the inclusion and exclusion criteria were enrolled from 26 hospitals,including Dongzhimen Hospital,Beijing University of Chinese Medicine,Xiaogan Central Hospital,and Yangzhou Hospital of Traditional Chinese Medicine,from June 1,2022,to September 30,2024.Patients were allocated 1:1 to either the experimental group receiving Shengxuebao Mixture or the control group receiving its simulator(placebo)using a block randomization method under double-blind conditions.Both groups received 15 mL orally three times daily for 28 consecutive days.The primary efficacy indicators included the hemoglobin(Hb)improvement rate(RHb)and the traditional Chinese medicine(TCM)syndrome improvement rate(RTCM)at week 4 of treatment.The secondary efficacy indicators encompassed Hb and red blood cell(RBC)count,Karnofsky Performance Status(KPS)score,TCM syndrome score,individual TCM symptom scores,and changes in each of these indicators compared to the baseline period at weeks 2,4,and 6 of treatment.Safety evaluations were conducted at week 4 of treatment.Results A total of 239 patients were enrolled,with 225 cases included in the Full Analysis Set(FAS)(109 in the experimental group vs.116 control group),163 in the Per Protocol Set(PPS)(77 vs.86),and 225 in the Safety Set(SS)(109 vs.116).Baseline characteristics between groups showed no significant differences.Significant differences were observed between the experimental and control groups in RHb at week 4(FAS:49.51%vs.35.24%,P<0.05;PPS:53.25%vs.36.05%,P<0.05)and RTCM at week 4(FAS:61.54%vs.39.62%,P<0.01;PPS:64.94%vs.40.70%,P<0.01).At weeks 2,4,and 6,the experimental group showed greater improvements in Hb and RBC counts than the control group.Additionally,the TCM syndrome scores were lower in the experimental group than in the control group at these time points.Except for week 2 in PPS,the KPS improvement was better in the experimental group than in the control group(P<0.05).The experimental group also demonstrated a greater reduction in scores for individual TCM symptoms such as spiritlessness and weakness,poor appetite and reduced food intake at weeks 4 and 6 compared to the control group(P<0.05,P<0.01).Furthermore,the reduction in vertigo score was more pronounced in the experimental group at week 6(P<0.01).For the score of pale and lusterless complexion,only in the PPS was the reduction from baseline more significant in the experimental group than in the control group at weeks 4 and 6(P<0.05).No significant differences were observed between the experimental and control groups in the incidence of all adverse events or drug-related adverse reactions.Conclusion Shengxuebao Mixture demonstrates significant efficacy in patients with CRA presenting syndrome of deficiency of liver and kidney combined with syndrome of deficiency of both qi and blood,effectively increasing Hb levels,ameliorating TCM syndromes,alleviating clinical symptoms,and enhancing functional status,with no significant difference in adverse drug reactions compared to the placebo.

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.
