Methods: Morphine 10mg and TDF 25μg/h were immediately used in 52 patients who had moderate-to-severe pain complicated by interventional embolization therapy, the pain intensity was evaluated by visual analogue scale (VAS). If VAS≥4 at t2 h after treatment, the dosage of TDF added into 50 μg/h. At 0h, 12h, 24h, 72h, 1 week, 2 weeks after TD, the vas and adverse events were observed respectively. Result: There was an obvious decrease in VAS at 12h after TDF treatment in the patients of which only 9 patients used 50ug/h dosage after partial splenic embolization (PSE) therapy. Most patients got satisfactory pain relief both the TDF 25 μg/h and TDF 50 μg/h group (VAS 0-1). The adverse events were nausea, vomiting and dizzy, especially in the TDF 50 μg/h group. No respiratory depression was observed and only one patient got retention of urine. Conclusion: TDF was effective and safe in the treatment of moderate-to-severe pain after interventional embolizafion therapy.展开更多

Methods: Fifty GEP-NETs patients with hepatic metastases were treated from January 2012 to December 2016, and received transarterial embolization (TAE) in the hepatic tumor or hepatic arterial infusion chemotherapy (HAIC). All patients received 179 times of the intervention therapy in total. Results: Blood supplies were identified in the 50 eases with angiography, which showed that 35 cases had abundant vessels, while 15 eases had poor blood supply. Twenty-two cases were found either collateral blood supply, or portal vein invasion or arterial-portal vein fistula. The best curative efficacy was complete remission (CR) in 4 cases, partial remission (PR) in 28 cases and stable disease (SD) in 18 eases during the process of treatment. The angiography (P=0.047) and the frequency of intervention (P=0.037) showed significantly statistical difference with Kaplan-Meier analysis. The Cox analysis showed that more than 3 times of interventional therapy was an independent prognostic factor. Conclusions: Interventional treatment is safe and effective for GEP-NETs, and is beneficial to patients with main hepatic metastases after endocrine therapy.展开更多

A Cox proportional hazard regression analysis was used to assess the long-term survival outcomes. The mean and median age of patients was 61 years(range 27-85 years). There were 115 males and 53 females in our study.RESULTS One hundred sixty-eight patients were enrolled in this study. The overall response rate was 28.9% in LSP patients and 27.3% in RSP patients. The disease control rate was 76.3% in LSP patients and 69.7% in RSP patients. The median overall survival in response to HAIC was 16.3 mo in the LSP arm and 9.3 mo in the RSP arm(P = 0.164). The median progression-free survival was 5.7 mo in the LSP arm and 4.2 mo in the RSP arm(P = 0.851).CONCLUSION There was no significant difference in survival between LSP patients and RSP patients after HAIC. Further prospective studies are needed to confirm these findings.展开更多

This study aimed to determine how to select patients who are not suitable for TACE as the first treatment choice. Methods: A total of 243 intermediate-stage HCC patients treated with TACE at three centers were retrospectively enrolled, of which 171 were used for model training and 72 for testing. Radiomics features were screened using the Spearman correlation analysis and the least absolute shrinkage and selection operator(LASSO) algorithm. Subsequently, a radiomics model was established using extreme gradient boosting(XGBoost) with 5-fold cross-validation. The Shapley additive explanations(SHAP) method was used to visualize the radiomics model. A clinical model was constructed using univariate and multivariate logistic regression. The combined model comprising the radiomics signature and clinical factors was then established. This model’s performance was evaluated by discrimination, calibration, and clinical application. Generalization ability was evaluated by the testing cohort. Finally, the model was used to analyze overall and progression-free survival of different groups. Results: A third of the patients(81/243) were unsuitable for TACE treatment. The combined model had a high degree of accuracy as it identified TACE-unsuitable cases, at a sensitivity, specificity, and area under the receiver operating characteristic curve(AUC) of 0.759, 0.885, 0.906 [95% confidence interval(CI): 0.859-0.953] in the training cohort and 0.826, 0.776, and 0.894(95% CI: 0.815-0.972) in the testing cohort, respectively. Conclusions: The high degree of accuracy of our clinical-radiomics model makes it clinically useful in identifying intermediate-stage HCC patients who are unsuitable for TACE treatment.展开更多

METHODS The anti-hepatocellular carcinoma activity of the Bax gene transferred to the human hepatocellular carcinoma QGY7703 cell line was examined. In addition the Bax gene was transferred in vivo in mice via the caudal vein or hepatic artery to investigate the differences in target organ and non-target organ transfection. RESULTS 1)The Bax gene mediated by a binary adenoviral vector system induced apoptosis in the human hepatic carcinoma QFY7703 cell line. The cell apoptotic rate in the experimental group (Bax) was 50.2±6.9% but only 32.1 ± 9.7% in the Ad/CMV-p53 group, showing that the Bax-apoptotic rate was significantly higher than the control group. 2) LacZ expression was higher in the target organ (liver) when given through the hepatic artery than through the tail vein. In contrast, LacZ expression in the nontarget organs was higher if given through the tail vein compared to the hepatic artery. CONCLUSION Superselective hepatic artery delivery with Bax gene therapy is safe, specific, effective and has low toxicity. This study provided the basis for Bax-gene therapy via the hepatic artery in vivo.展开更多

Methods: Morphine 10mg and TDF 25μg/h were immediately used in 52 patients who had moderate-to-severe pain complicated by interventional embolization therapy, the pain intensity was evaluated by visual analogue scale (VAS). If VAS≥4 at t2 h after treatment, the dosage of TDF added into 50 μg/h. At 0h, 12h, 24h, 72h, 1 week, 2 weeks after TD, the vas and adverse events were observed respectively. Result: There was an obvious decrease in VAS at 12h after TDF treatment in the patients of which only 9 patients used 50ug/h dosage after partial splenic embolization (PSE) therapy. Most patients got satisfactory pain relief both the TDF 25 μg/h and TDF 50 μg/h group (VAS 0-1). The adverse events were nausea, vomiting and dizzy, especially in the TDF 50 μg/h group. No respiratory depression was observed and only one patient got retention of urine. Conclusion: TDF was effective and safe in the treatment of moderate-to-severe pain after interventional embolizafion therapy.
文摘BACKGROUND Human cystic echinococcosis(CE)is a life-threatening zoonosis caused by the Echinococcus granulosus(sensu lato).Hepatocellular carcinoma(HCC)is a leading cause of cancer-related mortality in the world.The coexistence of CE and HCC is exceedingly rare,and only several well-documented cases have been reported.In addition to this coexistence,there is no report of the coexistence of CE,HCC,and liver abscess to date.Herein,we aimed to report a case of coexistence of liver abscess,hepatic CE,and HCC.CASE SUMMARY A 65-year-old herdsman presented to the department of interventional therapy with jaundice,right upper abdominal distension and pain for 10 d.Laboratory test showed that he had positive results for HBsAg,HBeAb,HBcAb,and echino-coccosis IgG antibody.The test also showed an increased level of alpha fetopro-tein of 3400 ng/mL.An abdominal computed tomography(CT)scan revealed an uneven enhanced lesion of the liver at the arterial phase with enhancement and was located S4/8 segment of the liver.In addition,CT scan also revealed a mass in the S6 segment of the liver with a thick calcified wall and according to current guideline and medical images,the diagnoses of hepatic CE(CE4 subtype)and HCC were established.Initially,transarterial chemoembolization was performed for HCC.In the follow-up,liver abscess occurred in addition to CE and HCC;thus,percutaneous liver puncture drainage was performed.In the next follow-up,CE and HCC were stable.The liver abscess was completely resolved,and the patient was discharged with no evidence of recurrence.CONCLUSION This is the first reported case on the coexistence of liver abscess,hepatic CE,and HCC.Individualized treatment and multidisciplinary discussions should be performed in this setting.Therefore,treatment and diagnosis should be based on the characteristics of liver abscess,hepatic CE,and HCC,and in future clinical work,it is necessary to be aware of the possibility of this complex composition of liver diseases.
文摘BACKGROUND Increasing data indicated that long noncoding RNAs(lncRNAs)were directly or indirectly involved in the occurrence and development of tumors,including hepatocellular carcinoma(HCC).Recent studies had found that the expression of lncRNA HAND2-AS1 was downregulated in HCC tissues,but its role in HCC progression is unclear.Ultrasound targeted microbubble destruction mediated gene transfection is a new method to overexpress genes.AIM To study the role of ultrasound microbubbles(UTMBs)mediated HAND2-AS1 in the progression of HCC,in order to provide a new reference for the treatment of HCC.METHODS In vitro,we transfected HAND2-AS1 siRNA into HepG2 cells by UTMBs,and detected cell proliferation,apoptosis,invasion and epithelial-mesenchymal transition(EMT)by cell counting kit-8 assay,flow cytometry,Transwell invasion assay and Western blotting,respectively.In addition,we transfected miR-837-5p mimic into UTMBs treated cells and observed the changes of cell behavior.Next,the UTMBs treated HepG2 cells were transfected together with miR-837-5p mimic and tissue inhibitor of matrix metalloproteinase-2(TIMP2)overexpression vector,and we detected cell proliferation,apoptosis,invasion and EMT.In vivo,we established a mouse model of subcutaneous transplantation of HepG2 cells and observed the effect of HAND2-AS1 silencing on tumor formation ability.RESULTS We found that UTMBs carrying HAND2-AS1 restricted cell proliferation,invasion,and EMT,encouraged apoptosis,and HAND2-AS1 silencing eliminated the effect of UTMBs.Additionally,miR-873-5p targets the gene HAND2-AS1,which also targets the 3’UTR of TIMP2.And miR-873-5p mimic counteracted the impact of HAND2-AS1.Further,miR-873-5p mimic solely or in combination with pcDNA-TIMP2 had been transformed into HepG2 cells exposed to UTMBs.We discovered that TIMP2 reversed the effect of miR-873-5p mimic caused by the blocked signalling cascade for matrix metalloproteinase(MMP)2/MMP9.In vivo results showed that HAND2-AS1 silencing significantly inhibited tumor formation in mice.CONCLUSION LncRNA HAND2-AS1 promotes TIMP2 expression by targeting miR-873-5p to inhibit HepG2 cell growth and delay HCC progression.

文摘Objective: To analyze the angiography appearance of liver metastases from gastroenteropancreatic neuroendocrine tumors (GEP-NETs), and evaluate the clinical efficacy and prognostic factors of interventional treatment for hepatic metastases. Methods: Fifty GEP-NETs patients with hepatic metastases were treated from January 2012 to December 2016, and received transarterial embolization (TAE) in the hepatic tumor or hepatic arterial infusion chemotherapy (HAIC). All patients received 179 times of the intervention therapy in total. Results: Blood supplies were identified in the 50 eases with angiography, which showed that 35 cases had abundant vessels, while 15 eases had poor blood supply. Twenty-two cases were found either collateral blood supply, or portal vein invasion or arterial-portal vein fistula. The best curative efficacy was complete remission (CR) in 4 cases, partial remission (PR) in 28 cases and stable disease (SD) in 18 eases during the process of treatment. The angiography (P=0.047) and the frequency of intervention (P=0.037) showed significantly statistical difference with Kaplan-Meier analysis. The Cox analysis showed that more than 3 times of interventional therapy was an independent prognostic factor. Conclusions: Interventional treatment is safe and effective for GEP-NETs, and is beneficial to patients with main hepatic metastases after endocrine therapy.

文摘AIM To analyze the survival data between patients diagnosed with right-sided primary(RSP) tumors and patients diagnosed with left-sided primary(LSP) tumors after hepatic arterial infusion chemotherapy(HAIC) at our center.METHODS A retrospective analysis of pretreated metastatic colorectal cancer patients who received HAIC from May 2006 to August 2015 was conducted. A Cox proportional hazard regression analysis was used to assess the long-term survival outcomes. The mean and median age of patients was 61 years(range 27-85 years). There were 115 males and 53 females in our study.RESULTS One hundred sixty-eight patients were enrolled in this study. The overall response rate was 28.9% in LSP patients and 27.3% in RSP patients. The disease control rate was 76.3% in LSP patients and 69.7% in RSP patients. The median overall survival in response to HAIC was 16.3 mo in the LSP arm and 9.3 mo in the RSP arm(P = 0.164). The median progression-free survival was 5.7 mo in the LSP arm and 4.2 mo in the RSP arm(P = 0.851).CONCLUSION There was no significant difference in survival between LSP patients and RSP patients after HAIC. Further prospective studies are needed to confirm these findings.

文摘Background: Although transarterial chemoembolization(TACE) is the first-line therapy for intermediatestage hepatocellular carcinoma(HCC), it is not suitable for all patients. This study aimed to determine how to select patients who are not suitable for TACE as the first treatment choice. Methods: A total of 243 intermediate-stage HCC patients treated with TACE at three centers were retrospectively enrolled, of which 171 were used for model training and 72 for testing. Radiomics features were screened using the Spearman correlation analysis and the least absolute shrinkage and selection operator(LASSO) algorithm. Subsequently, a radiomics model was established using extreme gradient boosting(XGBoost) with 5-fold cross-validation. The Shapley additive explanations(SHAP) method was used to visualize the radiomics model. A clinical model was constructed using univariate and multivariate logistic regression. The combined model comprising the radiomics signature and clinical factors was then established. This model’s performance was evaluated by discrimination, calibration, and clinical application. Generalization ability was evaluated by the testing cohort. Finally, the model was used to analyze overall and progression-free survival of different groups. Results: A third of the patients(81/243) were unsuitable for TACE treatment. The combined model had a high degree of accuracy as it identified TACE-unsuitable cases, at a sensitivity, specificity, and area under the receiver operating characteristic curve(AUC) of 0.759, 0.885, 0.906 [95% confidence interval(CI): 0.859-0.953] in the training cohort and 0.826, 0.776, and 0.894(95% CI: 0.815-0.972) in the testing cohort, respectively. Conclusions: The high degree of accuracy of our clinical-radiomics model makes it clinically useful in identifying intermediate-stage HCC patients who are unsuitable for TACE treatment.
文摘Background:Here we analyzed mid-term data of thoracic endovascular aneurysm repair(TEVAR)surgery with Castor single-branched stent graft placement for the management of Stanford type B aortic dissection(STBAD)involving the left subclavian artery(LSA).Methods:Between April 2014 and February 2019,32 patients with STBAD involving a Castor single-branched stent graft were included.We analyzed their outcomes,including technical success rate(TSR),surgical duration(SD),presence of ischemia,perioperative complications,LSA patency,and survival rate(SR),using computed tomography angiography and clinical evaluation during mid-term follow-up.Results:The mean patient age was 54.63±12.37 years(range,36–83 years).The TSR was 96.88%(n=31/32).The mean SD was 87.44±10.89 with a mean contrast volume of 125.31±19.30 mL.No neurological complications or deaths occurred during the study period.The patients had a mean hospital stay of 7.84±3.20 days.At a mean follow-up of 68.78±11.26 months,four non-aortic deaths(12.5%)were observed.The LSA patency rate was 100%(n=28/28).There was only one case of type I endoleak immediately after surgery(3.12%)(type I from LSA).However,none of the patients experienced type II endoleaks,and there were no cases of retrograde type A aortic dissection or stent graft-driven new distal entry.Finally,all patients exhibited good LSA patency.Conclusion:TEVAR using a Castor single-branched stent graft may be a highly feasible and efficient procedure for the management of STBAD involving the LSA.
文摘Owing to its heterogeneous and highly aggressive nature,hepatocellular carcinoma(HCC)has a high recurrence rate,which is a non-negligible problem despite the increasing number of available treatment options.Recent clinical trials have attempted to reduce the recurrence and develop innovative treatment options for patients with recurrent HCC.In the event of liver remnant recurrence,the currently available treatment options include repeat hepatectomy,salvage liver transplantation,tumor ablation,transcatheter arterial chemoembolization,stereotactic body radiotherapy,systemic therapies,and combination therapy.In this review,we summarize the strategies to reduce the recurrence of high-risk tumors and aggressive therapies for recurrent HCC.Additionally,we discuss methods to prevent HCC recurrence and prognostic models constructed based on predictors of recurrence to develop an appropriate surveillance program.

文摘Based on the latest classification by the International Society for the Study of Vascular Anomalies in 2018,vascular malformations(VMs)can be categorized into simple,combined,VMs of major named vessels,and VMs associated with other anomalies.Simple VMs include lymphatic,venous,capillary,and arteriovenous malformations(AVMs).AVMs represent disorders of direct arteriovenous shunts caused by the absence of a capillary bed between the involved arteries and veins.This abnormal vascular communication causes arterial blood to accumulate in the venous vessels,thus resulting in venous hypertension and characteristic clinical manifestations,such as pulsation,tremors,and elevated temperature.AVMs can occur sporadically or as manifestations of syndromic lesions and are considered among the most complex and challenging VMs.The diagnosis and treatment of AVMs can vary depending on the lesion location and associated clinical symptoms,thus complicating their management.Herein,we discuss peripheral AVMs in terms of their clinical manifestations,imaging examinations,and staging systems to provide a comprehensive reference for the treatment,evaluation methods,and follow-up procedures for this vascular anomaly.
文摘OBJECTIVE To explore the effects of cisplatin chemotherapy via the vein and the abdominal cavity on the functions of endothelial cells of mice with non-small cell lung cancer. METHODS 75 mice were divided equally into a untreated group, a group treated with chemotherapy (cisplatin: 2 mg/kg, 0.5 mL) via an intravenous method and a group treated with chemotherapy (cisplatin: 2 mg/kg, 0.5 mL) via an intraperitoneal method; changes in the morpholoqy and ultrastructure of vein endothelial cells were observed.
文摘OBJECTIVE To investigate apoptosis induced by Bax in hepatocellular carcinoma cells and to examine the results of 2 different routes for in vivo gene delivery. METHODS The anti-hepatocellular carcinoma activity of the Bax gene transferred to the human hepatocellular carcinoma QGY7703 cell line was examined. In addition the Bax gene was transferred in vivo in mice via the caudal vein or hepatic artery to investigate the differences in target organ and non-target organ transfection. RESULTS 1)The Bax gene mediated by a binary adenoviral vector system induced apoptosis in the human hepatic carcinoma QFY7703 cell line. The cell apoptotic rate in the experimental group (Bax) was 50.2±6.9% but only 32.1 ± 9.7% in the Ad/CMV-p53 group, showing that the Bax-apoptotic rate was significantly higher than the control group. 2) LacZ expression was higher in the target organ (liver) when given through the hepatic artery than through the tail vein. In contrast, LacZ expression in the nontarget organs was higher if given through the tail vein compared to the hepatic artery. CONCLUSION Superselective hepatic artery delivery with Bax gene therapy is safe, specific, effective and has low toxicity. This study provided the basis for Bax-gene therapy via the hepatic artery in vivo.

文摘BACKGROUND Cirrhosis results from persistent liver injury that leads to liver fibrosis.Immunological factors play important regulatory roles in the development and progression of cirrhosis.Bibliometrics is one of the most commonly used methods for systematic evaluation of a field of study.To date,there are no bibliometric studies on the role of immunological factors in cirrhosis.AIM To provide a comprehensive overview of the knowledge structure and research hotspots of immunological factors in cirrhosis.METHODS We retrieved publications related to immunological factors in cirrhosis between 2003 to 2022 from the Web of Science Core Collection database on December 7,2022.The search strategy was TS=((Liver Cirrhosis OR hepatic cirrhosis OR liver fibrosis)AND(Immunologic*Factor*OR Immune Factor*OR Immunomodulator*OR Biological Response Modifier*OR Biomodulator*)).Only original articles and reviews were included.A total of 2873 publications were analyzed using indicators of publication and citation metrics,countries,institutes,authors,journals,references,and keywords by CiteSpace and VOSviewer.RESULTS A total of 5104 authors from 1173 institutions across 51 countries published 2873 papers on cirrhosis and immunological factors in 281 journals.In the past 20 years,the increasing number of related annual publications and citations indicates that research on immunological factors in cirrhosis has become the focus of attention and has entered a period of accelerated development.The United States(781/27.18%),China(538/18.73%),and Germany(300/10.44%)were the leading countries in this field.Most of the top 10 authors were from the United States(4)and Germany(3),with Gershwin ME contributing the most related articles(42).World Journal of Gastroenterology was the most productive journal,whereas Hepatology was the most co-cited journal.Current research hotspots regarding immunological factors in cirrhosis include fibrosis,cirrhosis,inflammation,liver fibrosis,expression,hepatocellular carcinoma,activation,primary biliary cirrhosis,disease,and hepatic stellate cells.Burst keywords(e.g.,epidemiology,gut microbiota,and pathways)represent research frontiers that have attracted the interest of researchers in recent years.CONCLUSION This bibliometric study comprehensively summarizes the research developments and directions of immunological factors in cirrhosis,providing new ideas for promoting scientific research and clinical applications.
文摘BACKGROUND The prognostic assessment of patients after surgical resection of gastric cancer(GC)patients is critical.However,the role of the circadian clock gene NPAS2 expression in GC remains unknown.AIM To explore the relationship between NPAS2 and the survival prognosis of GC patients and clarify its role in evaluating GC prognosis.METHODS The tumor tissues and clinical data of 101 patients with GC were collected retrospectively.Immunohistochemical staining(IHC)was used to detect the expression of NPAS2 protein in GC and adjacent tissues.Univariate and multivariate Cox regression analysis was used to determine the independent prognostic factors of GC,and a nomogram prediction model was established.The receiver operating characteristic(ROC)curve,the ROC area under the curve,the calibration curve,and C-index were used to evaluate the predictive effectiveness of the model.Kaplan Meier analysis was used to compare the risk stratification of subgroups according to the median score in the nomogram model of each patient.RESULTS Microarray IHC analysis showed that the positive rate of NPAS2 protein expression in GC tissues was 65.35%,which was significantly higher than 30.69%in adjacent tissues.The high expression of NPAS2 was correlated with tumor-node-metastasis(TNM)stage(P<0.05),pN stage(P<0.05),metastasis(P<0.05),venous invasion(P<0.05),lymphatic invasion(P<0.05),and lymph node positive(P<0.05)of GC.Kaplan Meier survival analysis showed that the 3-year overall survival(OS)of patients with high NPAS2 expression was significantly shortened(P<0.0001).Univariate and multivariate COX regression analysis showed that TNM stage(P=0.009),metastasis(P=0.009),and NPAS2 expression(P=0.020)were independent prognostic factors of OS in GC patients for 3 years.The nomogram prediction model based on independent prognostic factors has a C-Index of 0.740(95%CI:0.713-0.767).Furthermore,subgroup analysis showed that the 3-year OS time of the high-risk group was significantly lower than that of the low-risk group(P<0.0001).CONCLUSION NPAS2 is highly expressed in GC tissues and is closely related to worse OS in patients.Therefore,the evaluation of NPAS2 expression may be a potential marker for GC prognosis evaluation.Notably,the nomogram model based on NPAS2 can improve the accuracy of GC prognosis prediction and assist clinicians in postoperative patient management and decision-making.

文摘BACKGROUND A noninvasive biomarker with high diagnostic performance is urgently needed for the early diagnosis of colorectal cancer(CRC).AIM To evaluate the diagnostic value of matrix metalloproteinases(MMPs)2,7 and 9 in urine for CRC.METHODS Of 59 healthy controls,47 patients with colon polyps and 82 patients with CRC were included in this study.Carcinoembryonic antigen(CEA)in serum and MMP2,MMP7,and MMP9 in urine were detected.The combined diagnostic model of the indicators was established by binary logistic regression.The receiver operating characteristic curve(ROC)of the subjects was used to evaluate the independent and combined diagnostic value of the indicators.RESULTS The MMP2,MMP7,MMP9,and CEA levels in the CRC group differed significantly from levels in the healthy controls(P<0.05).The levels of MMP7,MMP9,and CEA also differed significantly between the CRC group and the colon polyps group(P<0.05).The area under the curve(AUC)distinguishing between the healthy control and the CRC patients using the joint model with CEA,MMP2,MMP7 and MMP9 was 0.977,and the sensitivity and specificity were 95.10%and 91.50%,respectively.For early-stage CRC,the AUC was 0.975,and the sensitivity and specificity were 94.30%and 98.30%,respectively.For advanced stage CRC,the AUC was 0.979,and the sensitivity and specificity were 95.70%and 91.50%,respectively.Using CEA,MMP7 and MMP9 to jointly established a model distinguishing the colorectal polyp group from the CRC group,the AUC was 0.849,and the sensitivity and specificity were 84.10%and 70.20%,respectively.For early-stage CRC,the AUC was 0.818,and the sensitivity and specificity were 76.30%and 72.30%,respectively.For advanced stage CRC,the AUC was 0.875,and the sensitivity and specificity were 81.80%and 72.30%,respectively.CONCLUSION MMP2,MMP7 and MMP 9 may exhibit diagnostic value for the early detection of CRC and may serve as auxiliary diagnostic markers for CRC.
文摘BACKGROUND The combination of transarterial chemoembolization(TACE),lenvatinib,and programmed cell death 1(PD-1)inhibitor has been widely used in the treatment of advanced hepatocellular carcinoma(HCC)and has achieved promising results.However,there are few studies comparing whether drug-eluting beads TACE(DTACE)can bring more survival benefits to patients with large HCC compared to conventional TACE(C-TACE)in this triplet therapy.AIM To compare the efficacy and adverse events(AEs)of triple therapy comprising DTACE,PD-1 inhibitors,and lenvatinib(D-TACE-P-L)and C-TACE,PD-1 inhibitors,and lenvatinib(C-TACE-P-L)in patients with large HCC(maximum diameter≥5 cm),and analyze the prognostic factors.METHODS Following a comprehensive review of our hospital’s medical records,this retrospective study included 104 patients:50 received D-TACE-P-L,and 54 received CTACE-P-L.We employed Kaplan-Meier estimation to assess the median progression-free survival(PFS)between the two groups,utilized Cox multivariate regression analysis to identify prognostic factors,and applied theχ2 test to evaluate AEs.RESULTS The objective response rate(ORR)and median PFS were significantly higher in the D-TACE-P-L group compared to the C-TACE-P-L group(ORR:66.0%vs 44.4%,P=0.027;median PFS:6.8 months vs 5.0 months,P=0.041).Cox regression analysis identified treatment option,portal vein tumor thrombus,and hepatic vein invasion as protective factors for PFS.AEs were comparable between the two CONCLUSION D-TACE-P-L may have significantly better PFS and ORR for large HCC,while exhibiting similar AEs to C-TACE-PL.

文摘For gastrointestinal anastomosis,metallic biodegradable staples have a broad application potential.However,both magnesium and zinc alloys have relatively low strength to withstand the repeated peristalsis of the gastrointestinal tract.In this study,we developed a novel kind of biodegradable high-nitrogen iron(HN–Fe)alloy wires(0.23 mm),which were fabricated into the staples.The tensile results showed that the ultimate tensile strength and elongation of HN–Fe wires were 1023.2 MPa and 51.0%,respectively,which was much higher than those of other biodegradable wires.The degradation rate in vitro of HN–Fe wires was slightly higher than that of pure Fe wires.After 28 days of immersion,the tensile strength of HN–Fe wires remained not less than 240 MPa,meeting the clinical requirements.Furthermore,sixteen rabbits were enrolled to conduct a comparison experiment using HN–Fe and clinical Ti staples for gastroanastomosis.After 6 months of implantation,a homogeneous degradation product layer on HN–Fe staples was observed and no fracture occurred.The degradation rate of HN–Fe staples in vivo was significantly higher than that in vitro,and they were expected to be completely degraded in 2 years.Meanwhile,both benign cutting and closure performance of HN–Fe staples ensured that all the animals did not experience hemorrhage and anastomotic fistula during the observation.The anastomosis site healed without histopathological change,inflammatory reaction and abnormal blood routine and biochemistry,demonstrating good biocompatibility of HN–Fe staples.Thereby,the favorable performance makes the HN–Fe staples developed in this work a promising candidate for gastrointestinal anastomosis.

文摘In a recent issue of the World Journal of Gastrointestinal Surgery,a meta-analysis investigated the safety and efficacy of electrocautery-enhanced lumen-apposing metal stent(ECE-LAMS)implantation for managing malignant biliary obstruction following failed endoscopic retrograde cholangiopancreatography.This manusc-ript endeavors to offer a comprehensive look at the progression of endoscopic ultrasound-guided biliary drainage(EUS-BD)technologies,weighing their merits and drawbacks against traditional percutaneous methods.Several meta-analyses and randomized controlled trials have compared the performance of EUS-BD and percutaneous transhepatic cholangiodrainage(PTCD).These studies revealed that the technical success rate,clinical success rate,and adverse events were similar between EUS-BD and PTCD.Nevertheless,given that most of these studies preda-te 2015,the safety and effectiveness of novel EUS-BD techniques,including ECE-LAMS,compared with those of percutaneous biliary drainage remain elusive.Further investigation is imperative to ascertain whether these novel EUS-BD techniques can safely and efficaciously replace conventional percutaneous thera-peutic approaches.
文摘BACKGROUND Splenic rupture associated with Behçet’s syndrome(BS)is extremely rare,and there is no consensus on its management.In this case report,a patient with BSassociated splenic rupture was successfully treated with splenic artery embolization(SAE)and had a good prognosis after the intervention.CASE SUMMARY The patient was admitted for pain in the left upper abdominal quadrant.He was diagnosed with splenic rupture.Multiple oral and genital aphthous ulcers were observed,and acne scars were found on his back.He had a 2-year history of BS diagnosis,with symptoms of oral and genital ulcers.At that time,he was treated with oral corticosteroids for 1 month,but the symptoms did not alleviate.He underwent SAE to treat the rupture.On the first day after SAE,the patient reported a complete resolution of abdominal pain and was discharged 5 d later.Three months after the intervention,a computed tomography examination showed that the splenic hematoma had formed a stable cystic effusion,suggesting a good prognosis.CONCLUSION SAE might be a good choice for BS-associated splenic rupture based on good surgical practice and material selection.
