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 explore the application value of artificial intelligence (AI)-assisted chromosomal karyotype analysis in the diagnosis of prenatal chromosomal mosaicism. METHODS: A retrospective analysis was conducted on 172 pregnant women who underwent amniocentesis at the Department of Medical Genetics and Prenatal Diagnosis, the Third Affiliated Hospital of Zhengzhou University between January 2019 and December 2024. All cases whose fetuses were diagnosed with chromosomal mosaicism via karyotype analysis and stratified into two groups based on the analytical software employed: the conventional analysis group (n = 70), which utilized Leica analysis software for karyotype image recognition and cell counting; and the AI-assisted analysis group (n = 102), which utilized AI-assisted software for the same procedures. The clinical performance of AI-assisted karyotype analysis in diagnosing chromosomal mosaicism was comprehensively evaluated by comparing the types of mosaic karyotypes, distribution of mosaic ratios, and verification outcomes of different detection modalities between the two groups. This study was approved by the Medical Ethics Committee of the Third Affiliated Hospital of Zhengzhou University (Ethics No.: 2024-406-01). RESULTS: No statistically significant difference was observed in baseline characteristics (maternal age, gestational week, and indications for prenatal diagnosis) between the two groups. Regarding the detection efficacy for numerical and structural mosaicisms, no significant difference was found in the detection of numerical mosaicism. However, the conventional analysis group exhibited a significantly higher detection rate of autosomal structural mosaicism compared to the AI-assisted group (11.43% vs. 0.98%, P < 0.05). Numerical mosaicism cases were further verified using copy number variation sequencing (CNV-seq) and/or fluorescence in situ hybridization (FISH). The AI-assisted group demonstrated a significantly lower inconsistency rate (5.56% vs. 20.41%, P < 0.05) compared to the conventional group. For low-proportion (< 10%) chromosomal mosaicism, the AI-assisted group had a significantly lower detection rate (13.25% vs. 29.69%, P < 0.05). Subsequent validation of low-proportion mosaicism by CNV-seq and/or FISH showed a higher consistency rate in the AI-assisted group (81.82% vs. 54.55%), though the difference did not reach statistical significance (P = 0.360). CONCLUSION For the karyotyping analysis of prenatal chromosomal mosaicism, AI-assisted karyotype analysis shows high accuracy and consistency in identifying numerical chromosomal mosaicism, particularly in reducing the detection of low-proportion (< 10%) mosaicism while improving verification accuracy. AI-assisted analysis can significantly improve the detection accuracy of numerical mosaicism and mitigate the risk of misclassification for low-proportion (< 10%) mosaicism, thereby providing more precise clinical evidence for the prenatal diagnosis of chromosomal mosaicisms.

Objective:To analyze the value of abdominal CT angiography (CTA) and three-dimensional reconstruction fusion technology for larger (2 - 5 cm) gastric submucosal tumors (SMT) in the preoperative evaluation of super minimally invasive surgery(SMIS).Methods:A retrospective study was conducted, collecting data from 20 patients with gastric SMTs measuring 2 - 5 cm in diameter who were hospitalized in the the First Medical Center of the Chinese PLA General Hospital from March 2023 to December 2024. All patients underwent abdominal CTA prior to SMIS, and three-dimensional reconstructions of the tumors were performed. Clinical data were collected to analyze the visualization of the tumors and surrounding blood vessels in the fused three-dimensional images and the corresponding surgical plans.Results:In 19 cases, the abdominal CTA and three-dimensional imaging clearly and intuitively displayed the anatomical structures surrounding the tumors and provided panoramic images of small blood vessels around the tumors, enabling the selection of appropriate surgical plans. One case required conversion to laparoscopic surgery due to the intraoperative discovery of a small artery.Conclusions:The abdominal CTA examination and gastric SMT three dimensional reconstruction before SMIS can better display the anatomical location of the tumor and its relationship with surrounding small blood vessels, which is beneficial for gastroenterologists to formulate surgical plans and facilitate the smooth progress of SMIS under endoscopy.

Objective:To investigate the immunohistochemical expression pattern of phosphatase and tensin homolog deleted on chromosome ten(PTEN)protein with chromosome 10 deletion in endometrioid carcinoma(EEC)and its relationship with DNA mismatch repair(MMR)protein.Methods:A total of 121 patients diagnosed with EEC,endometrial atypical hyperplasia/endometrial intraepithelial neoplasia(EAH/EIN),and normal endome-trium due to uterine fibroid resection at Hubei Cancer Hospital Affiliated to Tongji Medical College of Huazhong U-niversity of Science and Technology from May 14,2019 to June 7,2023 were selected as the study subjects,inclu-ding 84 patients in the EEC group,17 patients in the EAH/EIN group,and 20 patients in the control group.Immu-nohistochemical was used to detect the expression patterns and differences of PTEN and MMR in endometrial tis-sues of three groups,and the differences in abnormal expression of PTEN protein in EEC between MMR protein deficient(MMRd)group and non-deficient(MMRp)group were compared.Results:①The expression of PTEN protein in 121 endometrial glandular epithelial cells includes four patterns:normal expression,negativeexpression,reduced expression,and heterogeneous expression.②The abnormal expression rates of PTEN protein in the EEC and EAH/EIN groups(84.5％and 94.1％)were higher than those in the control group(10.0％);The ex-pression rates of MMRd protein in the EEC group and EAH/EIN group(35.7％and 35.3％)were higher than those in the control group(0％),and the above differences were statistically significant(P＜0.05).③The abnor-mal expression rate of PTEN in the MMRd group was 96.7％,which was higher than that in the MMRp group(96.7％vs.77.8％,P=0.048).④In the EEC group,with normal and abnormal expression of PTEN protein,there was no statistically significant difference in the comparison of different pathological grades,muscle infiltration depth,lymph node metastasis,and lymphatic vessel invasion between the MMRd group and the MMRp group(P＞0.05).Conclusions:Identifying the abnormal expression pattern of PTEN protein and combining it with MMR protein detection can help identify endometrial dysplasia,and there may be a correlation between PTEN and MMR protein expression in EEC.The abnormal expression of PTEN may not have a clear impact on the biological behavior of MMRd expressing EEC.

Objective To explore the relationship between the degree of compression and shape grading of the cerebral cistern ambiens in hypertensive cerebral hemorrhage(HCH)patients after neural endoscopic intracranial hematoma evacuation(NEIHE)and prognosis.Methods 246 HCH patients who underwent NEIHE surgery from January 2020 to June 2023 were selected as the research subjects.According to the postoperative 6 month Glasgow outcome score(GOS),the patients were divided into good prognosis group(n=158)and poor prognosis group(n=88).Hierarchical regression model was used to analyze the relationship between clinical pathological features and the degree of compression and shape grading of the cerebral cistern ambiens.Multivariate logistic regression model was used to analyze the independent risk factors affecting the poor prognosis of patients with HCH after NEIHE,and a prediction model was constructed.Receiver operating characteristic curve(ROC curve)was drawn with poor prognosis as the outcome variable.Area under the curve(AUC),integrated discrimination improvement(IDI)and net reclassification improvement(NRI)of different prediction models were compared.Hosmer-Lemeshow was used to test the goodness of fit.Generalized additive model(GAM)was used to analyze the relationship between GOS and related factors.Results Compared with the good prognosis group,the poor prognosis group had more preoperative blood loss,lower preoperative Glasgow coma score(GCS),and higher proportion of patients with midline deviation,hypertension history ≥10 years,hemorrhage breaking into the brain ventricle,and operation time in the late stage,the differences were statistically significant(P＜0.05).Compared with the good prognosis group,the proportions of patients with ipsilateral and contralateral cerebral cistern ambiens compression of 3 to 4 points and the morphological classification of cerebral cistern ambiens of grade V in the poor prognosis group were higher,and the differences were statistically significant(P＜0.05).The location of bleeding,midline deviation,and intracranial pressure all had an impact on the degree of compression and morphological grading of the cerebral cistern ambiens,and the differences were statistically significant(P＜0.05).Multivariate Logistic regression analysis(model 2:including the degree of compression and shape grading of the cerebral cistern ambiens)showed that midline deviation,history of hypertension ≥10 years,preoperative bleeding volume＞37 mL,bleeding into the brain ventricles,preoperative GCS＜7 points,late surgical timing,degree of compression of the cerebral cistern ambiens(3 to 4 points on the same side of hematoma,3 to 4 points on the opposite side of hematoma),and grade V morphology were all risk factors influencing the poor prognosis of patients with HCH after NEIHE(P＜0.05).After incorporating the degree of compression and morphological grading of the cerebral cistern ambiens into model 1(excluding the degree of compression and shape grading of the cerebral cistern ambiens),the AUC increased to 0.812(95％CI:0.763～0.872),and both the IDI(0.081,95％CI:0.049～0.095)and NRI(0.611,95％CI:0.510～0.674)of the model improved,with statistically significant differences(P＜0.05).Compared with model 1,model 2 showed an increase in AUC(0.826,95％CI:0.771～0.863),IDI(0.085,95％CI:0.052～0.110),and NRI(0.628,95％CI:0.510～0.709),with statistically significant differences(P＜0.05).The Hosmer-Lemeshow test showed that model 2(P=0.878)had a better fit for predicting poor prognosis than model 1(P=0.691).GAM analysis showed that the higher the degree of compression and morphological grading of the cerebral cistern ambiens,the lower the GOS,and the difference was statistically significant(P＜0.05).ROC curve analysis showed that the combined application of degree of compression and morphological grading of the cerebral cistern ambiens had a high predictive value for poor prognosis,with AUC of 0.935(95％CI:0.890～0.971),sensitivity of 70.26％,and specificity of 93.84％.Conclusion The degree of compression and shape changes of the cerebral cistern ambiens in HCH patients after NEIHE are closely related to prognosis,and the combined application has certain predictive value for poor prognosis.The location of bleeding,midline deviation,intracranial pressure,and other factors significantly affect the compression degree and shape change of the cerebral cistern ambiens.

Objective To observe the impact of brain-computer interface(BCI)robot combined with task-oriented training(TOT)on hand function and activities of daily living in stroke patients.Methods A total of 40 patients with subacute stroke who were hospitalized in the Department of Rehabilitation Medicine of Anhui No.2 Province People's Hospital from December 2022 to December 2024 were prospectively and consecutively included in this study.The stroke patients were randomly assigned to the experimental group and the control group using the random number table method,with 20 cases in each group.Baseline data were collected from all patients,including gender,age,personal history(smoking,drinking),past medical history(hypertension,diabetes),stroke type(hemorrhagic stroke,ischemic stroke),hemiplegia side(left,right),disease course,stroke location(basal ganglia,internal capsule),and admission assessment indicators(including kinesthetic and visual imagery questionnaire[KVIQ-20]score,mini-mental state examination[MMSE]score and National Institutes of Health stroke scale[NIHSS]score).Both groups of patients received conventional rehabilitation training and TOT.The experimental group then underwent BCI robot training combined with TOT on this basis.Both groups received treatments for 4 weeks,and the upper limb and hand functions of all patients were evaluated using the Fugl-Meyer upper extremity function assessment scale(FMA-UE),the wrist-hand part of the FMA-UE scale(FMA-WH),the Wolf motor function test(WMFT),and the modified Ashworth scale(MAS)before and after the treatment;the hand function related part(feeding[10 score],bathing[5 score],dressing[10 score],grooming[5 score],and toilet using[10 score])of modified Barthel index(MBI)was used to assess the patients'hand dexterity to perform daily activities.Results(1)No statistically significant differences were found in the baseline data between the two groups of patients(all P＞0.05).(2)Before treatment,the scores of FMA-UE,FMA-WH,WMFT,MAS and hand function related score of MBI in the experimental group were(18.75±7.38),(2.95±1.54),(26.90±8.69),(1.10±0.66),and(15.45±1.82)respectively,while those in the control group were(15.90±5.39),(2.25±1.12),(24.15±6.78),(1.25±0.60),and(15.65±3.12)respectively.There were no statistically significant differences in the scores of FMA-UE,FMA-WH,WMFT,MAS and hand function related score of MBI between the two groups before treatment(all P＞0.05).After 4 weeks of treatment,the scores of FMA-UE,FMA-WH,WMFT,MAS and hand function related score of MBI in the experimental group were(27.10±7.76),(5.75±2.97),(40.85±10.19),(0.73±0.57),and(21.15±2.66)respectively,while those in the control group were(21.25±5.29),(4.00±1.49),(31.85±7.60),(0.73±0.64),and(17.40±3.14)respectively.The time main effects(Ftime values were 925.061,138.138,624.635 and 405.986 respectively,all P＜0.01),group main effects(Fgroup values were 4.460,4.562,5.011 and 4.411 respectively,all P＜0.05),and the interaction effects of time and group(Ftime×group values were 44.358,7.356,52.506 and 114.128 respectively,all P＜0.05)of FMA-UE,FMA-WH,WMFT and hand function related score of MBI scores were all significant.The time main effect of MAS scores was significant(Ftime value was 59.478,P＜0.01),while the group main effect(Fgroup value was 0.162,P＞0.05),the interaction effects of time and group(Ftime×group value was 1.652,P＞0.05)were not significant.Conclusion The combined task-oriented training with BCI robots can improve the upper limb and hand functions of stroke patients,enhance their ability to perform daily activities,and the effect is superior to that of single task-oriented training.

Objective·To investigate the effect of plasma exchange combined with classical chemotherapy on renal function in patients with multiple myeloma(MM).Methods·A retrospective analysis was conducted on data from patients newly diagnosed with MM in the Department of Hematology,Ruijin Hospital,Shanghai Jiao Tong University School of Medicine,between October 2021 and September 2023.Sixty-eight MM patients admitted from October 2021 to September 2022 served as the control group,and 41 patients admitted from October 2022 to September 2023 comprised the experimental group.The control group received classical chemotherapy for MM[PAD(bortezomib+adriamycin+dexamethasone)or PCD(bortezomib+cyclophosphamide+dexamethasone)],and the experimental group underwent plasma exchange before classic chemotherapy.The frequency of plasma exchange was determined according to the clearance rate of M-protein in patients,with the criterion being a reduction of more than 40%in plasma M-protein levels after exchange,and the total number of exchanges ranged from 1 to 3 sessions.After 2 chemotherapy courses,the free light chain difference(dFLC),serum creatinine(Scr),and other renal function indexes were compared between the two groups.Results·Compared with the control group,the experimental group showed no statistically significant difference in dFLC levels.The Scr level decreased[67.00(54.00,75.00)μmol/L vs 77.50(63.00,94.00)μmol/L,P=0.011],and the estimated glomerular filtration rate(eGFR)increased[97.80(92.80,101.30)mL/(min·1.73 m2)vs 85.80(61.35,95.35)mL/(min·1.73 m2),P<0.001]after treatment.Before treatment,the numbers of patients with MM-related severe renal injury[eGFR<50 mL/(min·1.73 m2)]were 41 in the control group and 28 in the experimental group.After treatment,8 patients(19.51%)in the control group achieved complete renal response[eGFR≥60 mL/(min·1.73 m2)],while 12 patients(42.86%)in the experimental group achieved the same,with the difference being statistically significant(P=0.036).After two courses of treatment,the overall response rates(ORR)of the control group and the experimental group were 76.47%and 92.68%,respectively,and the difference in overall therapeutic efficacy was statistically significant(P=0.031).Conclusion·Plasma exchange combined with classical chemotherapy can significantly reduce the Scr levels and increase eGFR in MM patients within a short period,ameliorating the MM-related renal impairment to some extent and improving clinical treatment outcomes.
