Objective To analyze the postoperative complications and survival outcomes of elderly patients with renal cell carcinoma undergoing laparoscopic surgery, and to identify the influencing factors, so as to provide reference for improving the safety of laparoscopic surgery in such patients. Methods A retrospective analysis was conducted on the clinical, surgical, and pathological data of 153 patients aged ≥75 years who underwent laparoscopic nephrectomy for renal cell carcinoma at our hospital during 2012 and 2025.Logistic regression analyses were performed to identify factors influencing postoperative complications, and a nomogram was constructed and validated to predict the complications.Kaplan-Meier method was used to draw the survival curve, and the effects of different surgical approaches on the prognosis and the survival difference in the age subgroups (75-＜80 years, ≥80 years) were analyzed.Cox regression analyses were conducted to determine factors affecting survival outcomes. Results Among the 153 patients, 15 developed postoperative complications, including 5 severe cases. Multivariate logistic regression identified Charlson Comorbidity Index (CCI) ≥3 and prolonged operation time as independent risk factors for postoperative complications (P＜0.05).The C-index of the logistic regression model constructed based on these factors (age, CCI≥3 and operation time) was 0.77 (95%CI:0.64-0.90), with an average absolute error of 1.6%.Subgroup analysis revealed superior overall survival in patients aged 75-＜80 years undergoing partial nephrectomy compared to radical nephrectomy (P=0.005 6).No statistically significant difference in overall survival was observed among patients ≥80 years who received different surgical approaches (P=0.062).Multivariate Cox regression analysis identified preoperative low albumin levels, preoperative renal insufficiency, tumor diameter＞4 cm, and pathological stage as independent risk factors for overall survival (P＜0.05). Conclusion Laparoscopic surgery is safe and effective for elderly patients with renal cell carcinoma, with survival outcomes correlated to nutritional status, renal function, tumor size and pathological staging.Patients aged ≥80 years still derive surgical benefit, and no survival differences exist between different surgical approaches in this age group.

Objective To screen the differential expression profile of circ_RNA in OSCC and to elucidate the molecular mechanism of circ_PVT1 on OSCC carcinogenesis.Methods The transcripts of 3 cases of OSCC and normal tissues were sequenced by high-throughput sequencing using circ_RNA expression profile chip,and the differential gene expression profiles were screened,and GO and KEGG enrichment analysis were performed.The expression level of PVT1 in OSCC tissues,human normal oral mucosal cells and OSCC cells was detected by qRT-PCR.The effect of PVT1 on the biological behavior of SCC-25 and SCC-9 cells was evaluated by MTT exper-iment,Transwell experiment and flow cytometry.The effect of PVT1 on the expression of key proteins in the Wnt3a/β-catenin pathway was evaluated by Western blot.The relationship between the expression of PVT1 and clinical pathological characteristics and prognosis of patients was further studied.Results A total of 403 differentially expressed circ_RNAs were screened by the chip,and the differen-tially expressed genes were enriched in pathways related to cancer progression.PVT1 was highly expressed in OSCC tissues and cells.Silencing PVT1 expression could inhibit the activation of the Wnt3a/β-catenin pathway,thereby effectively inhibiting the proliferation,migration,invasion and cell cycle of SCC-25 and SCC-9 cells and promoting apoptosis.PVT1 expression was only associated with lymph node metastasis and distant metastasis in patients,and those with high expression had a shorter PFS.Conclusion PVT1 promotes the progression of OSCC by regulating the activation of Wnt3a/β-catenin pathway.The research results provide new ideas for the diagnosis and treatment of OSCC.

Objective:To analyze the correlation of monocyte/high density lipoprotein ratio(MHR),neutrophil/lymphocyte ratio(NLR),platelet/lymphocyte ratio(PLR)and bone density,bone metabolism markers in elderly essential hypertension with osteoporosis(OP)patients.Methods:This study was a retrospective study,198 elderly essential hypertension patients who were admitted in our hospital from January 2022 to June 2024 were selected.According to the patient's bone mass test results,patients were divided into normal bone mass group(n=79),osteopenia group(n=68)and OP group(n=51).MHR,NLR,PLR,bone density(left hip,left femoral neck and lumbar spine L1-L4)and bone metabolism markers were compared among three groups,the correlation of MHR,NLR,PLR and bone density,bone metabolism markers were analyzed by Pearson correlation.Results:MHR,NLR,PLR in normal bone mass group,osteopenia group and OP group increased in turn(P＜0.05).The left hip,left femoral neck and lumbar spine L1-L4 bone density in normal bone mass group,osteopenia group,OP group decreased in turn(P＜0.05).25-hydroxyvitamin D[25(OH)D]in normal bone mass group,osteopenia group and OP group decreased in turn,alkaline phosphatase(ALP)and parathyroid hormone(PTH)increased in turn(P＜0.05).MHR,NLR and PLR were negatively correlated with left hip bone density,left femoral neck bone density,lumbar spine L1-L4 bone density,25(OH)D and positively correlated with PTH and ALP(P＜0.05).Conclusion:The increase of MHR,NLR and PLR in elderly essential hypertension with OP patients can affect bone mineral density and bone metabolism.

Following the evidence-based diagnosis and treatment guideline development method for common pediatric diseases,the The Guideline for the Diagnosis and Treatment of Pediatric Food Accumulation and Stagnation in Chinese Medicine was formed through literature retrieval,expert questionnaire survey,expert discussion meeting,and solicitation of opinions.The revised content includes the scope of the guideline,normative reference documents,terms and definitions,diagnosis,syndrome differentiation,treatment,pre-vention and nursing suggestions,etc.,aiming to update the clinical diagnosis and treatment plan of Chinese medicine for accumulation and provide important clinical decision-making references for clinical physicians to rationally apply the diagnosis and treatment plan of Chinese medicine in the prevention and treatment of accumulation and stagnation in Children.

Objective To investigate the role and molecular mechanism of SOX4 in Helicobacter pylori(H.pylori)-mediated gastric mucosal epithelial dysplasia.Methods The expression of SOX4 in gastric tissues and cells was analyzed with reverse transcription-polymerase chain reaction(RT-PCR),Western blotting,and immunohistochemical staining.The effects of SOX4 on gastric epithelial cell proliferation and colony formation were determined with CCK-8 and colony formation assays.A PCR array was used to screen downstream target genes involved in H.pylori-induced dysplasia mediated by SOX4.The transcriptional regulation and binding sites of the target gene MLH3 by SOX4 were elucidated with luciferase reporter assay,promoter truncation assay,and chromatin immunoprecipitation(ChIP).Results SOX4 expression was significantly increased in H.pylori-infected gastric tissues(P<0.05).Overexpression of SOX4 markedly enhanced the proliferation and colony formation abilities of normal gastric epithelial cells(P<0.05).Elevated SOX4 led to the dysregulation of MLH3 and other DNA damage repair-related molecules after H.pylori infection in gastric epithelial cells(|logFC|>1,P<0.05).H.pylori promoted MLH3 expression in gastric epithelial cells through SOX4.SOX4 transcriptionally activated MLH3 expression by binding to the 5th site of the MLH3 promoter.The increased expression of SOX4 and MLH3 is associated with poor prognosis of gastric cancer patients.Conclusion SOX4 is closely associated with H.pylori-induced dysplasia in gastric epithelial cells.Upregulation of SOX4 promotes H.pylori-related dysplasia by transcriptionally activating MLH3,leading to the imbalance of proliferation and colony formation in gastric epithelial cells.
