Objective To explore the safety of Yttrium-90 resin microsphere selective internal radiation therapy (⁹⁰Y-SIRT) on malignant liver tumors. Methods A retrospective analysis was conducted on 64 patients with malignant liver tumors who underwent ⁹⁰Y-SIRT from February 2023 to November 2024 at Weifang People’s Hospital. The clinical characteristics of the patients and the occurrence of adverse reactions after treatment were analyzed to assess the safety of ⁹⁰Y-SIRT. Results Among the 64 patients, there were 52 males (81.25%) and 12 females (18.75%); the average age was (56.29±11.08) years. Seven patients (10.94%) had tumors with maximum diameter of less than 5 cm, 38 patients (59.38%) had tumors with maximum diameter of 5-10 cm, and 19 patients (29.68%) had tumors with maximum diameter of greater than 10 cm. There were 47 cases (73.44%) of solitary lesions and 17 cases (26.56%) of multiple lesions; 53 cases (82.81%) were primary liver cancers and 11 cases (17.19%) were metastatic liver cancers. Of the 64 patients, 63 successfully completed the Technetium-99m macroaggregated albumin (^99mTc-MAA) perfusion test and received the ⁹⁰Y-SIRT; one patient received ⁹⁰Y-SIRT after the second ^99mTc-MAA perfusion test due to a work error. The most common adverse reactions included grade 1 alanine aminotransferase (ALT) elevation in 26 cases (40.62%) and grade 2 in 2 cases (9.37%), grade 1 aspartate aminotransferase (AST) elevation in 27 cases (42.18%) and grade 2 in 7 cases (10.93%); grade 1 nausea in 17 cases (26.56%) and grade 2 in 6 cases (9.37%); grade 1 abdominal pain in 12 cases (18.75%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%); grade 1 vomiting in 11 cases (17.18%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%). Conclusion The adverse reactions of ⁹⁰Y-SIRT for treating malignant liver tumors are mild, indicating good safety.

Objective To analyze the core genes of lung ischemia-reperfusion injury and construct a competitive endogenous RNA (ceRNA) network. Methods Original data of GSE145989 were downloaded from the Gene Expression Omnibus (GEO) database as the training set, and the GSE172222 and GSE9634 datasets were used as the validation sets, and the differentially-expressed genes (DEG) were identified. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed. Protein-protein interaction (PPI) network was constructed, and the core genes were screened, and the diagnostic values of these core genes and the immune infiltration levels of immune cells were evaluated. The ceRNA network was constructed and validated. The targeted drugs based on ceRNA network were assessed. Results A total of 179 DEG were identified, including 61 down-regulated and 118 up-regulated genes. GO analysis showed that DEGs were associated with multiple biological processes, such as cell migration, differentiation and regulation, etc. They were correlated with cell components, such as vesicle membrane, serosa and membrane raft, etc. They were also associated with multiple molecular functions, such as chemokine receptor, G protein-coupled receptor, immune receptor activity and antigen binding, etc. KEGG pathway enrichment analysis revealed that DEG were involved in tumor necrosis factor (TNF), Wnt, interleukin (IL)-17 and nuclear factor (NF)-κB signaling pathways, etc. PPI network suggested that CD8A, IL2RG, STAT1, CD3G and SYK were the core genes of lung ischemia-reperfusion injury. The ceRNA network prompted that miR-146a-3p, miR-28-5p and miR-593-3p were related to the expression level of CD3G. The miR-149-3p, miR-342-5p, miR-873-5p and miR-491-5p were correlated with the expression level of IL-2RG. The miR-194-3p, miR-512-3p, miR-377-3p and miR-590-3p were associated with the expression level of SYK. The miR-590-3p and miR-875-3p were related to the expression level of CD8A. The miR-143-5p, miR-1231, miR-590-3p and miR-875-3p were associated with the expression level of STAT1. There were 13 targeted drugs for CD3G, 4 targeted drugs for IL-2RG, 28 targeted drugs for SYK and 3 targeted drugs for lncRNA MUC2. No targeted drugs were identified for CD8A, STAT1 and other ceRNA network genes. Conclusions CD8A, IL2RG, STAT1, CD3G and SYK are the core genes of lung ischemia-reperfusion injury. The research and analysis of these core genes probably contribute to the diagnosis of lung ischemia-reperfusion injury and providing novel research ideas and therapeutic targets.

Objective To investigate the impacts of cinobufotalin combined with docetaxel+cisplatin chemotherapy on the disease control and the level of vascular endothelial growth factor(VEGF)in serum of patients with non-small cell lung cancer.Methods Totally 70 patients with non-small cell lung cancer admitted to Zhejiang Veteran Hospital from March 2019 to March 2022 were included.They were randomly divided into combination group(cinobufotalin combined with docetaxel+cisplatin,n= 35)and control group(docetaxel+cisplatin chemotherapy alone,n=35).The disease control rates of two groups,serum VEGF level,carcinoembryonic antigen(CEA),cy-tokeratin 19(CK19)and carbohydrate antigen 125(CA125)were measured using ELISA;life quality of patients was evaluated with the KPS score;The adverse events between two groups were compared.Results The disease control rate in the combination group(33/35,94.29％)was higher than that that of control group(25/35,71.43％,)(P＜0.05).After treatment,the level of VEGF in both groups of patients decreased,and the KPS score increased(P＜0.05)especially in the combination group(P＜0.05).After treatment,the level of serum CEA,CA125,and CK19 of control group and combination group were obviously lower than those before treatment(P＜0.05),while those in the combination group were even lower(P＜0.05).The incidence of adverse events in the combination group(5/35,14.29％)was lower than that in the control group(13/35,37.14％)(P＜0.05).Conclusions Cinobufotalin combined with docetaxel+cisplatin chemotherapy as a potential new chemotherapy significantly reduces the level of VEGF and tumor biomarkers in serum factor,improves the life quality of patients.The combined therapy is proved tobe safe.

Objective To construct a nomogram to predict the prognosis of patients with gallbladder cancer(GBC).Methods The clinicopathological data of GBC patients were extracted from the SEER database,and the independent prognostic factors of GBC patients were analyzed by Cox regression,and a nomogram was constructed.Finally,the column diagrams in the training queue and validation queue are verified.Results Age,T stage,M stage,histological grade,radiotherapy,surgery and tumor size were independent prognostic factors in GBC patients,and the differences were statistically significant(P＜0.05).In the training cohort,the C index was 0.735(95％CI=0.721～0.749),and the AUC values at 1,3 and 5 years were 0.821,0.820 and 0.833,respectively.In the verification group,the C index was 0.733(95％CI=0.711～0.755),and the AUC values for 1,3 and 5 years were 0.816,0.807 and 0.827,respectively.The calibration curve shows that the predicted values of the nomogram are in good agreement with the observed values.The decision curve shows that the nomogram model has better prediction ability than TNM staging system.Conclusion The constructed dynamic prognosis nomogram of GBC patients has high accuracy and reliability.

Objective To screen long non-coding RNA(lncRNA)associated with disulfidptosis and investigate the immune landscape between lncRNA and pancreatic cancer,for effective guidance in clinical practice.Methods The normal and pancreatic cancer tissue samples were obtained from The Cancer Genome Atlas database,and the lncRNA associated with disulfidptosis was identified based on the Cox and LASSO regression analyses.A risk prognosis model was constructed,and its predictive performance was verified using comprehensive methods.An accurate nomogram was construted to predict the prognosis of patients with pancreatic cancer.The biological differences were analyzed via Gene Ontology,Gene Set Enrichment Analysis,and an immunoassay.The immunotherapy response was estimated using the tumor mutational burden(TMB)score.Results A total of 251 disulfidptosis-related lncRNAs were successfully identified,and three groups of lncRNAs were selected as the reference for the risk model.Pathway analysis showed that immune-related pathways were associated with disulfidptosis-related lncRNA risk models.The risk score was significantly correlated with immune cell infiltration and the ESTIMATE score.Patients with higher risk scores had elevated TMB,indicating that high-risk patients exhibited a better immune checkpoint blockade response.Conclusion The findings of this study contribute to a deeper understanding of disulfidpto-sis-related lncRNA and provide a potential therapeutic strategy for pancreatic cancer.

Objective To investigate the expression of long non-coding RNA(lncRNA)LINC02695 in human retinal microvascular endothelial cells(HRMECs)in high glucose(HG)environment and its effect on the proliferation,migration and neovascularization of HRMECs.Methods HRMECs was divided into four groups:the normal glucose(NG)group(5.5 mmol/L),the HG group(30.0 mmol/L),the HG+LINC02695 silenced group(HG+si-LINC02695),and the HG+silenced control group(HG+si-NC).Real-time quantita-tive fluorescent PCR(qPCR)was used to detect the expression of LINC02695 and vascular endothelial growth factor(VEGF)mRNA in HRMECs of each group.The cell proliferation of each group was measured by Cell Counting Kit-8(CCK-8)method.The migration ability of cells in each group was detected by Transwell as-say.The tube forming ability of cells in each group was detected by tube forming experiment.Results The qPCR results showed that compared with the NG group,LINC02695 and VEGF were highly expressed in the HG group(P＜0.05).Compared with the HG group,VEGF mRNA expression level in the HG+si-LINC02695 group was significantly decreased(P＜0.05).The results of CCK-8 experiment showed that the proliferation ability of the HG group was significantly enhanced compared with the NG group(P＜0.05).Compared with the HG group,the cell proliferation ability of the HG+si-LINC02695 group was significantly decreased(P＜0.05).The results of Transwell experiment showed that the cell migration ability of the HG group was significantly increased compared with the NG group(P＜0.05).Compared with the HG group,the cell migration ability of the HG+si-LINC02695 group was significantly decreased(P＜0.05).The results of tube formation experiment showed that compared with the NG group,the tube formation ability of the HG group was significantly increased(P＜0.05).Compared with the HG group,canalization ability of cells in the HG+si-LINC02695 group was significantly decreased(P＜0.05).Conclusion LINC02695 may be involved in promoting the proliferation,migration and angiogenesis of HRMECs induced by HG.

Objective:To accurately measure the dynamic changes of peri-implant soft tissue within one year after the immediate implant placement and provisionalization with the modified socket-shield technique (MSST) in the esthetic zone, and to provide a basis for evaluating the effect of the modified socket-shield technique on the maintenance of peri-implant soft tissue.Methods:A total of 22 patients (22 implants) were prospectively included 1 year after completion of immediate implant placement and provisionalization (IIPP) within MSST in the esthetic zone from January 2022 to January 2024 at the Department of Oral Implantology in the Stomatological Hospital of Chongqing Medical University. The intraoral optical models of patients were obtained by an intraoral scanner system preoperatively and at 3, 6, and 12 months postoperatively, respectively. The standard tessellation language files of intraoral optical models at multiple time points were imported to Geomagic Studio 2013 to be superimposed and aligned for analyzing the peri-implant soft tissue contour on the labial side of the implant site at multiple levels. The amount of gingival margin recession, gingival papilla change, and thickness change of the labial side of the soft tissues at each postoperative point in time were measured at each postoperative time point, as well as evaluating the esthetic effect by the pink esthetic score (PES).Results:The patients were (40±13) years old (21-75 years), including 9 males and 13 females. No adverse events occurred in all the implants during the 12-month follow-up period. The recession level of the gingival margin of the implant site (GL) was 0.08 (0.07) mm, the recession level of the mesial papilla (ML) was 0.19 (0.25) mm, and the recession level of the distal papilla (DL) was 0.19 (0.10) mm. The average collapse thickness of the soft tissue contour on the labial side of the implant (ΔD) was (0.39±0.09) mm, mainly occurring within 2 mm of the root of the gingival margin. The height of the alveolar bone was reduced by (0.17±0.08) mm. The thickness of the labial alveolar bone at 1, 3, and 5 mm root side of the implant shoulder was reduced by (0.13±0.08), (0.12±0.10) and 0.04 (0.17) mm, respectively. The postoperative pink esthetic score was 13.00 (2.25) points at 12 months, which suggested that all implant sites achieved ideal esthetic results.Conclusions:The labial soft tissue contour at implant sites shows minimal change following immediate implant placement and provisionalization using the modified socket-shield technique for 1 year in the esthetic zone.

Objective: To explore the factors affecting the prevalence of HIV-associated neurocognitive disorders (HAND) among HIV/AIDS patients, so as to provide insights into developing HAND prevention measures. Methods: HIV/AIDS patients aged 18 years and above in the Infection Department of Nanjing Second Hospital were selected.Demographic data, treatment regimen and blood biochemical indicators were collected. Depression was evaluated using Patient Health Questionnaire Depression Scale, frailty was evaluated using Chinese version of Tilburg Frailty Indicator, and HAND was evaluated by Montreal Cognitive Assessment Scale. Factors affecting HAND were analyzed using a multivariable logistic regression model. Results: Totally 440 questionnaires were allocated and 426 valid questionnaires were recovered, with an effective rate of 96.82%. The median age of patients investigated was 33.00 (interquartile range, 10.00) year. There were 407 males, accounting for 95.54%; 232 patients with bachelor degree or above, accounting for 54.46%; 171 patients with HAND, accounting for 40.14%. Multivariable logistic regression analysis showed that educational level (bachelor degree or above, OR=0.291, 95%CI: 0.157-0.541), depression (OR=2.499, 95%CI: 1.530-4.083), frailty (OR=2.121, 95%CI: 1.307-3.441) and treatment regimen including efavirenz (OR=2.223, 95%CI: 1.367-3.615) were the influencing factors for HAND among HIV/AIDS patients. Conclusion Educational level, depression, frailty and use of efavirenz may be associated with HAND risk.

Objective To investigate the value of quantitative parameters(Kep and Ktrans)of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI),in predicting perineural invasion(PNI)in peripheral prostate cancer(PCa).Methods The clinical and preoperative MRI data of 45 patients with peripheral PCa who underwent radical prostatectomy(RP)were analyzed retrospectively.According to the pathological results,the patients were divided into PNI group(n=27)and non-PNI group(n=18).Various parameters,including age,total prostate specific antigen(tPSA),Ktrans value,Kep value,apparent diffusion coefficient(ADC)value,prostate volume,maximum lesion diameter,and prostate-specific antigen density(PSAD)were compared between the two groups.Multivariate logistic regression analysis was used to identify independent predictors of PNI,and a joint prediction model was established.The DeLong test was used to compare differences in the area under the curve(AUC)between the joint prediction model and each independent predictor.Results The univariate analysis identified statistically significant differences in the tPSA,Ktrans value,ADC value,maximum lesion diameter,and PSAD between the two groups(P＜0.01).The multivariate analysis showed that the Ktrans value and the maximum lesion diameter were independent predictors of PNI,with AUC of 0.854 and 0.874,respectively(P＜0.01).The AUC of the joint prediction model for PNI diagnosis was 0.955(P＜0.001).The DeLong test showed that the AUC of the joint prediction model for PNI diagnosis was better than that of the Ktrans and the maximum lesion diameter(P＜0.05).Conclusion The Ktrans value can be used to predict PNI.Furthermore,the combination of the Ktrans value and the maximum lesion diameter is more effective for predicting PNI than traditional methods.This provides more reference basis for the selection of clinical treatment methods.
