Renal injury is one of the common ad-verse reactions in the clinical application of chemo-therapy drugs,which is the main reason why the chemotherapy can not be carried out in the whole cycle.The pathological mechanism of chemothera-py-induced renal injury is very complicated,mainly involving oxidative stress,inflammatory response,apoptosis,mitochondrial dysfunction,and regula-tion of transporters,causing pathological damage to renal tubules or glomeruli.At present,there is no specific pharmacological intervention for the treatment of chemotherapy-induced renal injury.As a treasure of traditional Chinese medicine,tradi-tional Chinese medicine has the advantages of overall regulation,multi-targeting,small adverse re-actions and no obvious drug dependence in the prevention and treatment of chemotherapy-in-duced renal injury.In recent years,there have been more and more studies on the intervention of che-motherapy-induced renal injury by multi-compo-nent and multi-directional intervention of active components,extracts and compounds of tradition-al Chinese medicine,and some progress has been made.A large number of studies have shown that the potential mechanisms of traditional Chinese medicine in preventing and treating renal injury in-duced by chemotherapy include inhibiting oxida-tive stress,reducing inflammatory response and in-hibiting apoptosis.Although there are many stud-ies on the mechanism of action of traditional Chi-nese medicine in the treatment of chemotherapy-induced renal injury,there is still a lack of systemat-ic review.Based on this,this paper summarizes the mechanism of renal injury induced by chemothera-py and the intervention of traditional Chinese medi-cine,so as to provide theoretical support for its clinical treatment and new drug innovation.

Objective:To analyze the clinical features associated with pelvic lymph node metastasis(PLNM)in prostate cancer and to construct a preoperative prediction model for PLNM,thereby reducing unnecessary extended pelvic lymph node dissection(ePLND).Methods:Based on predefined inclusion and exclusion criteria,344 patients who underwent radical prostatectomy and ePLND at the First Affilia-ted Hospital of Zhengzhou University between 2014 and 2024 were retrospectively enrolled,among whom,77 patients(22.4％)were pathologically confirmed to have lymph node-positive disease.The clinical characteristics,MRI reports,and pathological results were collected.The data were then randomly divi-ded into a training cohort(241 cases,70％)and a validation cohort(103 cases,30％).Univariate and multivariate Logistic regression analysis were employed to construct a preoperative prediction model for PLNM.Results:Univariate Logistic regression analysis revealed that total prostate specific antigen(tPSA)(P=0.021),free prostate specific antigen(fPSA)(P=0.002),fPSA to tPSA ratio(fPSA/tPSA)(P=0.011),percentage of positive biopsy cores(P＜0.001),prostate imaging reporting and data system(PI-RADS)score(P=0.004),biopsy Gleason score ≥8(P=0.005),clinical T stage(P＜0.001),and MRI-indicated lymph node involvement(MRI-LNI)(P＜0.001)were significant predictors of PLNM.Multivariate Logistic regression analysis demonstrated that the percentage of positive biopsy cores(OR=91.24,95％CI:13.34-968.68),PI-RADS score(OR=7.64,95％ CI:1.78-138.06),and MRI-LNI(OR=4.67,95％ CI:1.74-13.24)were independent risk factors for PLNM.And a novel nomogram for predicting PLNM was developed by integrating all these three variables.Com-pared with the individual predictors:percentage of positive biopsy cores[area under curve(AUC)=0.806],PI-RADS score(AUC=0.679),and MRI-LNI(AUC=0.768),the multivariate model incor-porating all three variables demonstrated significantly superior predictive performance(AUC=0.883).Consistently,calibration curves and decision curve analyses confirmed that the multivariable model had high predictive accuracy and provided significant net clinical benefit relative to single-variable models.And using a cutoff of 6％,the multiparameter model missed only approximately 5.2％of PLNM cases(4/77),while reducing approximately 53％of ePLND procedures(139/267),demonstrating favorable predictive efficacy.Conclusion:Percentage of positive biopsy cores,PI-RADS score and MRI-LNI are independent risk factors for PLNM.The constructed multivariate model significantly improves predictive efficacy,offering a valuable tool to guide clinical decisions on ePLND.

Objective:To explore the regulatory mechanism of voltage-dependent anion channel 1(VDAC1) on the proliferation, migration and invasion of lung adenocarcinoma(LUAD) cells.Methods:This study employed a combination of bioinformatics and experimental validation methods, conducting bioinformatics analysis and cytological experimental validation in the central laboratory of the School of Medicine, Anhui University of Science and Technology from February 2023 to August 2024.Clinical histological specimen validation was performed using immunohistochemistry, and a retrospective analysis was conducted on 5 cases of lung adenocarcinoma and adjacent samples from Huai′an First People′s Hospital affiliated with Nanjing Medical University. The TCGA network database was analyzed for the expression pattern, prognostic value, and functional enrichment of VDAC1 in LUAD. A549 cells with VDAC1 knockdown and H1650 cells with VDAC1 overexpression were established through lentiviral transfection. The expression difference of VDAC1 protein in LUAD and adjacent tissue specimens was detected by immunohistochemistry.The effects of VDAC1 on the proliferation, migration, and invasion capabilities were explored through CCK8 assay, scratch healing assay, and Transwell assay.The activation levels of epithelial-mesenchymal transition (EMT) marker proteins, cell cycle-dependent kinases, and molecules in the PI3K/AKT/mTOR signaling pathway were detected by Western blot.Results:Bioinformatics analysis revealed that VDAC1 was highly expressed in LUAD cells ( P<0.000 1) and was an independent risk factor for LUAD ( P<0.000 1). Functional enrichment analysis showed significant enrichment of the PI3K/AKT/mTOR, G2M checkpoint, and P53 signaling pathways ( P<0.001). Compared to adjacent control tissues, the expression level of VDAC1 protein is higher in lung adenocarcinoma tissues.Overexpression of VDAC1 promoted the proliferation ( P<0.000 1), migration, and invasion( P<0.01) of H1650 cells, while knockdown of VDAC1 inhibited the proliferation ( P<0.000 1), migration, and invasion ( P<0.05) of A549 cells.Western Blot experiments showed that compared to the control group, the expression levels of vimentin (1.10±0.11 vs 2.39±0.15, P<0.001), N-cadherin (0.94±0.12 vs 2.72±0.06, P<0.001), CDK1 (0.93±0.04 vs 1.53±0.03, P<0.000 1), CDK2 (1.04±0.13 vs 2.29±0.06, P<0.001), CDK4 (0.90±0.03 vs 2.00±0.11, P<0.01), p-PI3K (1.08±0.13 vs 1.85±0.12, P<0.01), and p-AKT (1.03±0.11 vs 1.69±0.06, P<0.001) were increased in H1650 cells overexpressing VDAC1, while E-cadherin expression decreased (2.18±0.14 vs 0.997±0.11, P<0.001).In contrast, in A549 cells with VDAC1 knockdown, the expression levels of vimentin (1.70±0.26 vs 0.97±0.09, P<0.05), N-cadherin (1.98±0.25 vs 1.03±0.06, P<0.05), CDK1 (1.13±0.03 vs 0.95±0.02, P<0.01), CDK2 (2.29±0.12 vs 0.92±0.10, P<0.001), CDK4 (1.71±0.096 vs 1.12±0.11, P<0.01), p-PI3K (1.67±0.09 vs 0.97±0.03, P<0.001), and p-AKT (1.53±0.04 vs 1.02±0.03, P<0.000 1) decreased, while E-cadherin expression increased (1.04±0.04 vs 1.85±0.26, P<0.05). Conclusions:VDAC1 may promote the proliferation, migration, and invasion of LUAD cells by activating EMT and cyclin-dependent kinases through the PI3K/AKT/mTOR pathway.

Objective To investigate the relationship between CT lung volume parameters(CT-LVP)and pulmonary function grade in patients with idiopathic pulmonary fibrosis(IPF)and its prediction of acute exacerbation.Methods A total of 204 patients with IPF were selected and divided into mild group(67 cases),moderate group(72 cases)and severe group(65 cases)according to the semi-quantitative scoring method of high-resolution computed tomography(HRCT).The correlation between CT-LVP and pul-monary function parameters(PFP)were analyzed.The predictive value of CT-LVP for acute exacerbation in severe IPF was ana-lyzed.Results The whole lung volume(WLV),normal lung volume(NLV)and normal lung volume percentage(NLV%)in severe group were lower than those in mild and moderate groups,whereas interstitial lung disease volume(ILDV)and interstitial lung disease volume percentage(ILDV%)were higher than those in mild and moderate groups,with statistical significance(P<0.05).WLV,NLV,ILDV,NLV%,ILDV%showed strong correlations with forced expiratory volume in 1 second percentage(FEV1%),forced expiratory volume in 1 second to forced vital capacity ratio(FEV1/FVC),diffusing capacity of the lung for carbon monoxide percent-age(DLCO%),and residual volume to total lung capacity ratio(RV/TLC).Receiver operating characteristic(ROC)curve analysis showed that the combination of WLV,NLV,ILDV,NLV%and ILDV%had higher accuracy in predicting acute exacerbation,area under the curve(AUC)>0.75(P<0.05).Conclusion CT-LVP is closely related to PFP,and the accuracy of CT-LVP combination in predicting acute exacerbation is high,which provides a theoretical basis for preventing acute exacerbation of IPF.

Spinal cord injury （SCI） is a prevalent neurological disorder that often results in motor， sensory， cognitive， balance， and walking impairments， and can even lead to pain， significantly affecting the physical and mental health and quality of life of patients. Conventional treatment methods， primarily conducted in hospital settings， tend to be monotonous and lack engagement， leading to low patients’ compliance， motivation and cooperation. In contrast， virtual reality （VR） technology can serve as an effective adjunctive therapeutic approach， immersing patients in simulated virtual environments for functional training in specific contexts and tasks， thereby providing a sense of real experience to achieve assessment and therapeutic outcomes. The interactive and engaging nature of VR technology markedly enhances patients’ interest and motivation in treatment， offering new possibilities for home-based rehabilitation and presenting patients with alternative treatment options. This review systematically introduces the application of VR technology in the treatment of patients with SCI， focusing on its roles in assessing functional impairments， improving motor function， enhancing balance and walking abilities， alleviating pain， and promoting recovery from cognitive and psychological disorders， as well as its impact on other functional impairments and its combined use with other technologies. Furthermore， this article delves into the current advantages and limitations of VR technology， aiming to deepen the understanding of VR among physicians and therapists， promote its widespread clinical application， advance the field of rehabilitation medicine， provide theoretical foundations and directions for future research， and offer new insights and references for clinical practice.

Objective: To explore the safety and feasibility of the disconnection of the left renal artery preferentially during robot-assisted inferior vena cava (IVC) thrombectomy for patients with left renal cell carcinoma and tumor emboli. Methods: Clinical data of 7 patients who underwent robot-assisted IVC thrombectomy and radical nephrectomy in the First Affiliated Hospital of Zhengzhou University during Dec.2021 and Oct.2024 were retrospectively analyzed.Thrombectomy was performed first，followed by nephrectomy. The “IVC-first, kidney-last”robotic technique was developed to minimize chances of IVC thrombus. When patients in left lateral decubitus position, the left renal artery was severed from the right side through the inferior vena cava and abdominal aorta. After removal of thrombus from IVC was completed, patients changed to the right lateral position to complete radical left nephrectomy. Results: Imaging examinations revealed that the median diameter of the renal cell carcinomas was 83(46-99) mm; the median length of the inferior vena cava cancerous emboli was 49(2-91) mm.According to the Mayo classification，the cancerous emboli were gradeⅠ in 2 cases，gradeⅡ in 4 cases，and grade Ⅲ in 1 case.All surgeries were successful.The median operation time was 248(201-331) minutes，blood loss 500(200-1000) mL，and 6 cases required intraoperative blood transfusion.The median time for transition into the intensive care unit was 1(1-4) days，and drainage tube removal 6(5-12) days.Serum creatinine increased significantly in 5 cases，4 of which returned to normal after 1 week，but 1 had renal insufficiency (creatinine 166 μmol/L).Chylous fistula occurred in 1 patient，and lower extremity venous thrombosis developed in 3 patients.Pathological examinations indicated 6 cases of renal cell carcinoma and 1 case of MiT family translocation renal cell carcinoma.During the median follow-up of 17(1-35) months，5 cases were tumor-free，while 2 had lung and retroperitoneal metastases.They received targeted therapy of axitinib combined immunotheraphy and lived with tumors. Conclusion: In the left lateral position for left renal cell carcinoma with cancerous emboli，robot-assisted laparoscopic thrombectomy by crossing the inferior vena cava and abdominal aorta and disconnecting the left renal artery first is safe and feasible.

BACKGROUND:Spinal cord injury is a neurological disorder caused by traumatic or non-traumatic events,often leading to severe functional impairment below the injured segment.In recent years,neural stem cell transplantation has been considered to have significant therapeutic potential in regulating the inflammatory response after spinal cord injury,inhibiting excessive proliferation of glial scars,and promoting nerve regeneration. OBJECTIVE:To review and discuss the potential mechanism of action of acupuncture and neural stem cell transplantation therapy in inhibiting spinal cord injury-induced secondary injury,and to delve into the scientific basis for its treatment of spinal cord injury. METHODS:PubMed,Elsevier,WanFang,and CNKI databases were searched using"spinal cord injury,acupuncture,neural stem cells,SDF-1α/CXCR4 axis"as Chinese and English search terms.Totally 96 articles were finally included.The research findings of acupuncture combined with neural stem cells in the treatment of spinal cord injury were summarized and analyzed,and the mechanism of this combination therapy in the treatment of secondary injury after spinal cord injury was summarized. RESULTS AND CONCLUSION:(1)The stromal-derived factor 1α(SDF-1α)/chemokine receptor 4(CXCR4)axis plays a crucial role in neural stem cell transplantation for spinal cord injury.This signaling mechanism not only affects neural stem cell migration,proliferation,and differentiation,but is also a key factor in determining the efficiency of stem cell homing to the injury site.Therefore,the regulation of targeting this axis is of great significance in enhancing the therapeutic effect of spinal cord injury.(2)Acupuncture,as a traditional Chinese medicine therapy,shows unique advantages in the regulation of secondary injury in spinal cord injury.It can effectively reduce secondary injury after spinal cord injury by regulating inflammatory response,inhibiting apoptosis,improving microcirculation,reducing glial scar formation,and counteracting oxidative stress.(3)Acupuncture was also able to influence the expression and function of the SDF-1α/CXCR4 axis,thereby enhancing the homing and survival ability of neural stem cells and promoting nerve regeneration and functional recovery.(4)The therapy combining acupuncture and stem cell transplantation is an innovative treatment strategy for spinal cord injury and suitable for repairing neural circuits.It combines the wisdom of traditional Chinese medicine with the advantages of modern biotechnology,providing a new treatment option for spinal cord injury patients.However,this combination therapy is still in the research and exploration stage,and its long-term efficacy and safety need to be further verified.(5)Taken together,acupuncture and neural stem cell transplantation for the treatment of spinal cord injury has great potential for clinical application,but in-depth research and optimization of treatment options are still needed.In the future,we look forward to further revealing the efficacy mechanism and optimal indications of this therapy through more clinical trials and mechanism studies,so as to bring better hope of recovery and more efficient therapeutic effects to spinal cord injury patients.

Objective:To study the feasibility of detecting vertical semicircular canal function and to analyze the three-dimensional(3D)characteristics and normal reference value in healthy young people.Methods:This was a cross-sectional study conducted from January to June 2024. A three-axis rotating chair was used to perform vertical sinusoidal rotation on 52 healthy young adults (26 males and 26 females, aged 18-40 years) in the left anterior-right posterior (LARP) and right anterior-left posterior (RALP) semicircular canal planes. For each plane, nystagmus was induced with six combinations of different angles and velocity front and back rotation angles of ±30°,±60°,±90°, and velocities of 40°/s and 80°/s, the slow phase velocity (SPV) and their symmetry of 3D nystagmus were analyzed. SPSS 20.0 was used to compare the statistical differences in these two parameters across different stimulation protocols.Results:There were no spontaneous nystagmus in the 52 subjects, and all tests were finished. Except the combinations of (±30°-40°/s), three components of nystagmus were induced stably in the rest of the stimulations. The SPVs of vertical components were no statistically insignificant ( P>0.05), and some horizontal or torsion components were statistically significant ( P<0.05). The 95% reference range of the symmetry was≤25% in the vertical and≤30% in the torsional component of the nystagmus except for (±30°-80°/s), the symmetry was 32.2% and 49.2% respectively. The trend changes of the three components were consistent, among which the vertical and torsional components induced by (±60°-80°/s) and (±90°-80°/s) were the best, the SPV value of the vertical components was higher in the latter group than the former apart from the front RALP, while no significant difference was found in the torsional components ( P>0.05). Conclusion:The (±90°-80°/s) combination is the optimal method to detect the function of vertical semicircular canal in 3D chair test. When observing torsional component, the combining scheme of (±60°-80°/s) and (±90°-80°/s) is better. Considering tolerance, the (±60°-80°/s) combination is recommended.
