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 explore risk factors for metachronous tumor lesions after radical resection of rectal cancer (RC). Methods A retrospective study was conducted on 757 RC patients who underwent RC radical surgery at the Sixth Affiliated Hospital, Sun Yat-sen University from October 2012 to June 2018. The patients were divided into early-onset RC group (EO-RC group, ＜50 years old, n=228) and average-onset RC group (AO-RC group, ≥ 50 years old, n=529) based on their age of diagnosis, and were followed up until March 2025. General information, initial colonoscopy, follow-up colonoscopy, and other relevant clinical information were collected from all patients. The risk of developing metachronous tumor lesions was compared between two groups using Kaplan Meier (K-M) risk function; univariate and multivariate Cox proportional hazards models were used to analyze the influencing factors of metachronous tumor lesions after RC radical surgery. Results The median follow-up time was 30 (15, 58) months. The K-M risk function showed that the risk of developing metachronous tumor lesions in the EO-RC group was significantly lower than that in the AO-RC group (P＜0.001). The results of the multivariate Cox proportional hazards model showed that the risk of metachronous tumor lesions after RC surgery in the EO-RC group was 50.8% of that in the AO-RC group (P＜0.001); PIK3CA mutation and synchronous advanced adenoma were independent risk factors for metachronous tumor lesions after RC surgery (HR=2.360, 2.094; P=0.003, P＜0.001). Conclusions RC patients with advanced age, PIK3CA mutations, and synchronous advanced adenomas are prone to developing metachronous tumor lesions after surgery. Patients with EO-RC may not require intensified colonoscopy surveillance postoperatively. However, intensified surveillance strategies should be considered for RC patients harboring PIK3CA mutations or presenting with synchronous advanced adenomas.

Objective:To summarize the clinical characteristics of elderly patients with stage Ⅰ diffuse large B-cell lymphoma (DLBCL) and analyze the factors associated with prognosis.Methods:A case series study was conducted by retrospectively collecting clinical data from patients aged over 60 years with newly diagnosed stage Ⅰ DLBCL across 20 medical centers in Jiangsu Province, China, between June 2010 and April 2023. The involved site, classification and treatment plan were summarized. The primary endpoints were progression-free survival (PFS) and overall survival (OS). Statistical analyses were performed using the Kaplan-Meier method, and Cox regression model.Results:The study included 255 patients with a median age of 69 years, of whom 130 (51.0%) were male, 66 (25.9%) were aged ≥75 years and 26 (10.1%) had a high Charlson Comorbidity Index (CCI) score of ≥2. Extranodal involvement was observed in 163 (63.9%) patients, with the stomach (37.4%, 61/163), intestine (19.0%, 31/163), testes (11.0%, 18/163), and breast (7.4%, 12/163) being the most frequently affected sites. The non-germinal center B-cell (non-GCB) subtype was prevalent in 63.7% of patients (142/223), with no significant difference between the nodal and extranodal groups ( P=0.681). Furthermore, 73.9% (184/249) and 11.7% (29/249) of patients received the R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) and R-miniCHOP regimen, respectively. The overall 3-year PFS rate was 81.5%, and the 3-year OS rate was 85.6%. Patients aged ≥75 years ( HR=2.910, 95% CI 1.565-5.408, P=0.001) and/or with a CCI score ≥2 ( HR=2.324, 95% CI 1.141-4.732, P=0.020) had a significantly poorer PFS. Incorporating age ≥75 years and CCI score ≥2 into the stage-modified international prognostic index (sm-IPI) can better stratify the prognosis of elderly patients with stage Ⅰ DLBCL. The 3-year PFS rate was 48.7% in the high-risk group versus 85.7% in the low-risk group ( P<0.001). Conclusions:Our findings show that the elderly patients with stage Ⅰ DLBCL were predominantly characterized by extranodal involvement (particularly in the stomach and intestinal tract) and non-GCB subtype. Age ≥75 years and CCI ≥2 were identified as independent prognostic factors. The newly established sm-IPI-75-CCI incorporating these factors demonstrated superior prognostic discrimination compared to conventional risk assessment systems.

Objective To evaluate the safety and efficacy of transcatheter arterial chemoembolization(TACE)combined with lenvatinib and camrelizumab in the treatment of advanced hepatocellular carcinoma(HCC).Methods The clinical data of a total of 63 patients with advanced HCC,who received TACE combined with lenvatinib and camrelizumab(triple therapy)or TACE combined with lenvatinib(dual therapy)at the Jingmen Municipal People's Hospital of China between April 2020 and December 2021,were retrospectively analyzed.Triple therapy group had 30 patients,and dual therapy group had 33 patients.The post-treatment tumor response,disease progression-free survival(PFS),overall survival(OS),and the incidence of adverse drug reactions were recorded.Results The median follow-up period of the two groups was 14 months(range of 4-26 months).Compared with the dual therapy group,in the triple therapy group the objective response rate(ORR)was remarkably higher(83.3%vs.57.6%,P=0.026),the disease control rate(DCR)was obviously higher(93.3%vs.69.7%,P=0.039),the median PFS was significantly longer(8.0 months vs.5.0 months,P＜0.01),and the median OS was strikingly longer(24.0 months vs.12.0 months,P=0.004).No statistically significant difference in the incidence of adverse drug reactions existed between the two groups(P＞0.05).Conclusion For the treatment of advanced HCC,TACE combined with lenvatinib and camrelizumab is clinically safe and effective.(J Intervent Radiol,2024,32:57-62)

Objective:To analyse the clinical significance of selective single embryo transfer by time-lapse mo-nitoring(TLM)or conventional morphology assessment(CMA)in vitro fertilization/intracytoplasmic sperm in-jection and embryo transfer(IVF/ICSI-ET),and to initially explore the predictive value of Raman spectral analy-sis of embryo culture medium for clinical pregnancy rate.Methods:The study is a prospective randomized con-trolled clinical trial.We assigned 139 patients treated with IVF/ICSI-ET in Reproductive and Genetics Center of Suzhou Municipal Hospital from April 2019 to July 2020,which were randomly assigned to either the CMA or the TLM group.We performed selective single-embryo transfer(fresh cycle and FET)after selecting the optimal em-bryos with TLM or CMA respectively.If the patient's first embryo transfer was unsuccessful,a second one would be performed to compare the differences in the cumulative live birth rate of embryo transfer and other pregnancy outcomes between the two groups.Meanwhile,we collected 15 μl of embryo culture medium at day 3 after IVF/ISCI fertilization for Raman spectroscopy analysis.Results:There were no differences in cumulative live birth,cu-mulative clinical pregnancy,cumulative premature birth,cumulative early spontaneous abortion,cumulative ectopic pregnancy and LGA or SGA between TLM and CMA groups(P＞0.05).The Neonatal sex ratio in the TLM group was lower than that in the CMA group,but the difference was not significant(P＞0.05).Raman spectros-copy analysis of embryo culture medium predicted the clinical pregnancy rate with 67.21％accuracy.Conclu-sions:In young women with a good ovarian reserve,the advantage of using TLM to evaluate embryos is not obvi-ous,so we should remain vigilant that embryo selection based on morphokinetic parameters may affect the sex ratio.Raman spectroscopic analysis of embryo culture medium is not yet able to effectively predict the planting ability of embryos.

Objective:To evaluate the effect of patent foramen ovale (PFO) on the perioperative complications and survival rate in pediatric patients undergoing living donor liver transplantation.Methods:The medical records from pediatric patients of either sex with biliary atresia, aged<18 yr, who underwent living donor liver transplantation from January 2020 to January 2022, were retrospectively collected. The pediatric patients were divided into PFO group and non-PFO group according to the results of echocardiography before operation. The postreperfusion syndrome, acute lung injury, acute kidney injury, postoperative delirium and 1-year survival rate were recorded.Results:There was no significant difference in the incidence of postreperfusion syndrome, acute lung injury, acute kidney injury, postoperative delirium and one-year survival rate between PFO group and non-PFO group ( P>0.05). Conclusions:PFO has no obvious effect on the incidece of intraoperative and early postoperative complications and 1-year survival rate in pediatric patients undergoing living donor liver transplantation.
