This study was designed to assess the clinical efficiency and long-term outcomes of hepatic vein (HV) and accessory hepatic vein (AHV) recanalization in patients with HV-type Budd-Chiari syndrome (BCS).A total of 27 patients with HV-type BCS underwent AHV recanalization and 94 patients had HV recanalization at our center from January 2012 to December 2019. The treatment effectiveness and long-term outcomes were compared.Technical success was accomplished in all patients, without any procedure-related complications. The clinical success rates were 96.3% (26/27) and 95.7% (90/94) (Our findings suggest that AHV could be employed as a replacement for HV, as a hepatic drainage vein, in HV-type BCS patients.

Multi-session transarterial chemoembolization (TACE) is usually needed for the treatment of intermediate-stage hepatocellular carcinoma (HCC), but it may not always have a positive influence on prognosis due to high heterogeneity of HCC. To avoid ineffective repeated TACE, the concept of TACE failure/refractoriness has been proposed by several organizations and is being addressed using tyrosine kinase inhibitors. The concept of TACE failure/refractoriness is controversial due to ambiguous definitions and low evidence-based data. To date, only a few studies have examined the rationality concerning the definition of TACE failure/refractoriness, although the concept has been introduced and applied in many TACE-related clinical trials. This review focuses on some of the issues related to different versions of TACE failure/refractoriness, the rationality of related definitions, and the feasibility of continuing TACE after so-called failure/refractoriness based on published evidence. A suggestion to re-define TAEC failure/refractoriness is also put forward.

BACKGROUND. Drug-eluting bead transarterial chemoembolization (DEB-TACE) has emerged as an alternative to conventional TACE (cTACE) for treatment of hepatocellular carcinoma (HCC), although selecti...

Based on an artificial intelligence approach, this study attempted to establish prognostic models to predict 3-month overt hepatic encephalopathy (OHE) occurrence, 1-year mortality, and liver dysfunction for cirrhotic patients with acute variceal bleeding (AVB) treated with early transjugular intrahepatic portosystemic shunt (TIPS) creation. This retrospective study included patients treated with early TIPS between January 2016 and November 2019. Independent risk factors associated with occurrence of OHE within 3 months, 1-year mortality, and liver dysfunction after early TIPS were identified using univariate and multivariate logistic analyses. Artificial neural network (ANN) models and prognostic nomograms based on the independent risk factors were established and validated internally. A total of 207 patients were included, with 33 (15.9%) experienced OHE within 3 months after TIPS creation. The albumin-bilirubin grade (P = 0.015), age (≤ 65, > 65 years) (P

To compare the safety and efficacy of integrated iodine-125 (I-125) seed implantation (sequential implantation of helical I-125 seed implant into the main portal vein and of I-125 seeds into the branch tumor thrombus directly forming main portal vein tumor thrombus (MPVTT)) combined with transarterial chemoembolization (TACE) versus TACE alone for hepatocellular carcinoma (HCC) with MPVTT. From December 2016 to January 2020, 46 HCC patients with MPVTT were analyzed. In the combination group, 21 patients received helical I-125 seed implantation in the main portal vein through a patent small portal vein branch and TACE in a single session. After 7–10 days, I-125 seeds were implanted percutaneously into the branch tumor thrombus directly forming MPVTT. In the TACE group, 25 patients received TACE alone. Thereafter, TACE was repeated as needed in both groups. Adverse events, tumor response, and overall survival (OS) of the two groups were compared. No adverse events grade ≥ 3 were observed in either group. The optimal objective response rate and disease control rate for MPVTT in the combination group and TACE group were 52.4% versus 4.0% (P

Background Epithelial-mesenchymal transition (EMT) has been associated with wound healing, tumorigenesis, and metastasis. Circular RNAs (circRNAs) are functional non-coding RNAs involved in multiple human cancers. However, whether and how circRNAs contribute to the EMT in hepatocellular carcinomas (HCC) remains to be deciphered. In this study, we investigated the regulation and function of hsa_circ_0003288 on programmed death-1 ligand 1 (PD-L1) during EMT and HCC invasiveness. Methods Hsa_circ_0003288 expression was measured by real-time quantitative reverse transcriptase PCR (qRT-PCR). Luciferase reporter assays, RNA pull-down assay and fluorescence in situ hybridization (FISH) were used to determine the correlation between hsa_circ_0003288 and miR-145 and between miR-145 and PD-L1. Furthermore, ectopic overexpression and siRNA-mediated downregulation of hsa_circ_0003288, transwell assays, and in vivo studies were used to determine the function of hsa_circ_0003288 on the EMT and invasiveness of L02 and HCC cells. Results miR-145 directly targeted the PD-L1 3′-untranslated region (UTR) region, and hsa_circ_0003288 acted as a miR-145 sponge to regulate PD-L1 expression. Overexpression of hsa_circ_0003288 increased PD-L1 levels and promoted EMT, migration, and invasiveness of L02 cells. These observations were reversed after knockdown of hsa_circ_0003288 in HepG2 and Huh7 cells. Overexpression of PD-L1 rescued EMT, migration, and invasiveness of HepG2 and Huh7 cells after knockdown of hsa_circ_0003288. Furthermore, hsa_circ_0003288 knockdown reduced EMT in in vivo studies. Hsa_circ_0003288/PD-L1 axis was found to mediate the metastatic phenotypes via the PI3K/Akt pathway in HCC. Additionally, expression levels of hsa_circ_0003288 were increased and positively correlated with PD-L1 expression in HCC tissues. Conclusion Our findings demonstrated that hsa_circ_0003288 promoted EMT and invasion of HCC via the hsa_circ_0003288/miR-145/PD-L1 axis through the PI3K/Akt pathway. Targeting hsa_circ_0003288 may be a therapeutic strategy for the treatment of HCC.

Background and Aims The recognition of transarterial chemoembolization (TACE) failure/refractoriness among Chinese clinicians remains unclear. Using an online survey conducted by the Chinese College of Interventionalists (CCI), the aim of this study was to explore the recognition of TACE failure/refractoriness and review TACE application for hepatocellular carcinoma (HCC) treatment in clinical practice. Methods From 27 August 2020 to 30 August 2020 during the CCI 2020 annual meeting, a survey with 34 questions was sent by email to 264 CCI clinicians in China with more than 10 years of experience using TACE for HCC treatment. Results A total of 257 clinicians participated and responded to the survey. Most participants agreed that the concept of “TACE failure/refractoriness” has scientific and clinical significance (n=191, 74.3%). Nearly half of these participants chose TACE-based combination treatment as subsequent therapy after so-called TACE failure/refractoriness (n=88, 46.1%). None of the existing TACE failure/refractoriness definitions were widely accepted by the participants; thus, it is necessary to re-define this concept for the treatment of HCC in China (n=235, 91.4%). Most participants agreed that continuing TACE should be performed for patients with preserved liver function, presenting portal vein tumor thrombosis (n=242, 94.2%) or extrahepatic spread (n=253, 98.4%), after the previous TACE treatment to control intrahepatic lesion(s). Conclusions There is an obvious difference in the recognition of TACE failure/refractoriness among Chinese clinicians based on existing definitions. Further work should be carried out to re-define TACE failure/refractoriness.

Purpose: The study aimed to establish a prognostic prediction model and an artificial neural network (ANN) model to determine who will benefit from transarterial chemoembolization (TACE) monotherapy for patients with hepatocellular carcinoma (HCC) invading portal vein. Methods: Treatment-naïve patients with HCC and portal vein invasion who were treated with TACE monotherapy at hospital A as training cohort and hospital B as validation cohort were included. The primary endpoint was overall survival (OS). In training cohort, independent risk factors associated with OS were identified by univariate and multivariate analysis. The prognostic prediction (PP) and ANN models based on the independent risk factors were established to find out who will benefit most from TACE monotherapy. The type of portal vein tumor thrombosis was classified based on the Cheng’s Classification. The accuracy of the models was validated in validation cohort. Results: Totally, 242 patients (training cohort: n ​= ​159; validation cohort: n ​= ​83) were included. The median OS was 7.1 and 8.5 months in training and validation cohort, respectively. In training cohort, the PP model was established based on the following five independent risk factors: Cheng’s Classification, Eastern Cooperative Oncology Group score, maximum tumor size, number of HCC nodules, and Child-Pugh stage. PP score of 17.5 was identified as cut-off point and patients were divided into two groups by PP score 17.5 in survival benefit and prognostication (8.8 vs. 5.5 months; P ​

To explore the outcomes of combined transarterial chemoembolization (TACE) with sorafenib in hepatocellular carcinoma (HCC) patients with portal vein tumour thrombus (PVTT) and to establish a prognostic prediction nomogram to differentiate target patients and stratify risk. This multicentre, retrospective study consisted of 185 consecutive treatment-naive patients with HCC and PVTT treated with TACE plus sorafenib from three institutions between January 1st, 2012 and December 31st, 2017. The primary outcome measurement of the study was overall survival (OS). The type of PVTT was classified by the Liver Cancer Study Group of Japan. The prognostic nomogram was established based on the predictors and was performed with interval validation. The median OS of the Vp1-3 and Vp4 groups was 12.4 months (11.7–18.9) and 8.5 months (7.6–11.2) (P = 0.00098), respectively, and there was a significant difference in the median OS between the Vp1-2 and Vp3 subgroups (16.4 months (12.2–27.9) vs. 10.9 months (8.4–18.1), P = 0.041). The multivariate Cox regression analysis suggested that tumour size, albumin-bilirubin grade, and PVTT type were independent prognostic factors. The C-index value of the nomogram based on these predictors in the entire cohort was 0.731 (0.628–0.833). After the combined therapy of TACE and sorafenib, advanced HCC patients with segmental or subsegmental PVTT showed better survival than those with main PVTT. The nomogram can be applied to identify advanced HCC patients with PVTT who may benefit most from the combination treatment and be helpful for making decision in clinical practice.

In this article, the updated status of interventional radiology (IR) in China is reported and compared vs that a decade ago based on a poll carried out in 2017 in Jiangsu Province, where the economy and overall health level are among the best of the 31 provinces in China. All 98 polled centers responded, and 56 IR departments (57%) had become independent departments separate from the radiology department; 74 (76%) had inpatient wards. In 2017, there were 538 interventional radiologists performing IR procedures in Jiangsu Province, with a total of 69,277 procedures performed, with interventional oncologic procedures accounting for the largest proportion (58%).

Background To detect the right atrial (RA) functions in hypertrophic cardiomyopathy (HCM) patients by using volume-derived values and two-dimensional strain. Methods Thirty-two HCM patients and 34 age and gender matched normal controls were enrolled for this study. RA volume-derived values were measured by using 2D ultrasonic images. RA strain (S-reservoir, S-conduit, S-booster pump) and strain rate (SR-reservoir, SR-conduit, SR-booster pump), representing the reservoir, conduit and booster pump functions, respectively, were measured by EchoPAC. Results Total RA emptying fraction (RAEF) and RA expansion index in HCM patients were significantly lower than normal controls (p p Conclusions In this study, we concluded that RA dysfunctions, including the reservoir and conduit functions were impaired in HCM patients.

Six pigs underwent implantation of a portal vein infusion port by transjugular access. The technical success rate was 100% (n = 6), with no surgical complications or deaths. At 1 month after implantation, the catheter tip had moved from the splenic vein to the main portal vein, while the catheter protruded into the right ventricle through the right atrium in all cases. Hence, the infusion port system has not been used in clinical practice due to its obvious displacement after implantation. However, this study provides a new idea for future exploration of portal vein infusion pathways.

Osteosarcoma is the most common type of malignant bone tumor, which has an overall survival rate of only 15-30%. The present study aimed to investigate the effects of 15-hydroxy-6α,12-epoxy-7β,10αH,11βH-spiroax-4-ene-12-one (HESEO), a compound extracted from the endophytic fungus Penicillium sp. FJ-1 isolated from Avicennia marina, on the proliferation of osteosarcoma cells and to explore its underlying mechanisms of action. Cell number was counted to measure the cell proliferation. JC-1 reagent was used to measure mitochondrial membrane potential. ELISA was used to measure the cytochrome c level and caspase activities. Apoptosis was detected by Annexin V-Propidium Iodide staining. Gene and protein expression were measured by reverse-transcription-PCR and western blot analysis, respectively. Additionally, the anti-tumor effects of HESEO were explored within a syngeneic osteosarcoma tumor model. The results suggested that HESEO significantly inhibited the proliferation of osteosarcoma cells and induced apoptosis of MG-63 cells, evidenced by their decreased mitochondrial membrane potential, and increased cytochrome c release, caspase activities and percentage of apoptotic cells. In addition, HESEO increased the expression of pro-apoptotic genes and proteins compared with control cells. The results indicated that HESEO may act through increasing p53 upregulated modulator of apoptosis expression. Furthermore, HESEO treatment significantly increased the survival time and decreased the tumor burden of osteosarcoma tumor-bearing mice compared with vehicle treatment. Furthermore, combined treatment with HESEO enhanced the effects of the chemotherapeutic agent methotrexate on a lung metastasis osteosarcoma model. These data suggested that HESEO could be developed as a potential anti-tumor agent against osteosarcoma.

Background: Deep vein thrombosis (DVT) is a common cardiovascular emergency that may have life-threatening complications, including pulmonary embolism (PE) and post-thrombotic syndrome (PTS). Conventional anticoagulant medication does not completely dissolve the clots and does not decrease the risk of DVT complications. Invasive catheter-directed thrombolysis (CDT) is an approach that has been reported to reduce the reoccurrence of PTS during acute DVT. We compared balloon-assisted CDT with routine CDT in the treatment of acute DVT and evaluated the clinical efficacy and safety of balloon-assisted CDT. Methods: This retrospective cohort study included 94 patients diagnosed with a first episode of DVT in the lower extremities and treated from September 2008 to February 2018. The patients underwent routine CDT (group A, n ​= ​50) or balloon-assisted CDT (group B, n ​= ​44) based on their enrollment date. We obtained the circumference difference between the limbs, the degree of clot lysis, and the lysis rate as parameters for evaluating the two approaches. The PE incidence and bleeding amount were recorded. We also compared the total urokinase dose, treatment duration, and retrieval rate of optional filters. Results: Swelling was significantly alleviated in both groups, as indicated by a reduction in the limb circumference. Patients who underwent balloon-assisted CDT exhibited significantly lower thrombus scores compared with the routine group (S ​= ​1403.50, Z ​= ​−5.7702, P ​

Objectives:This study aimed to evaluate the association between different body composition features with prognostic outcomes of intermediate stage hepatocellular carcinoma (HCC) patients treated with transarterial chemoembolization (TACE).Methods:The areas and density of skeletal muscle area (SM) and adipose tissue [subcutaneous (SAT); visceral (VAT)] were calculated on the pre-TACE CT scans. Overall survival (OS) and progression-free survival (PFS) curves were calculated using the Kaplan–Meier method and compared with log-rank test. The discrimination and performance of body composition features were measured by area under time-dependent receiver operating characteristic (ROC) curve. Univariate and multivariate Cox proportional hazard analyses were applied to identify the association between body composition parameters and outcomes.Results:A significant prolonged OS and PFS was displayed by Kaplan–Meier curve analysis for HCC patients with VAT HU below −89.1 (25.1 months, 95% CI: 18.1–32.1 vs. 17.6 months, 95% CI: 16.3–18.8,p< 0.0001, 15.4 months, 95% CI: 10.6–20.2 vs. 6.6 months, 95% CI: 4.9–8.3,p< 0.0001, respectively). The 1-, 2-, 3-, and 5-year OS area under the curve (AUC) values of the VAT HU were higher than the other body composition parameters. Meanwhile, it is also found that 3-, 6-, 9-, and 12-month PFS AUC values of VAT HU were the highest among all the parameters. Univariate and multivariate Cox-regression analysis suggested a significant association between VAT density and outcomes (OS, HR: 1.015, 95% CI: 1.004–1.025,p= 0.005, PFS, HR: 1.026, 95% CI: 1.016–1.036,p< 0.0001, respectively).Conclusion:The VAT density could provide prognostic prediction value and may be helpful to stratify the intermediate stage HCC patients.

Transarterial chemoembolization (TACE) is widely applied for the treatment of hepatocellular carcinoma. Repeat TACE is often required in clinical practice because a satisfactory tumor response may not be achieved with a single session. However, repeated TACE procedures can impair liver function and increase treatment-related adverse events, all of which prompted the introduction of the concept of "TACE failure/refractoriness". Mainly based on evidence from two retrospective studies conducted in Japan, sorafenib is recommended as the first choice for subsequent treatment after TACE failure/refractoriness. Several studies have investigated the outcomes of other subsequent treatments, including locoregional, other molecular targeted, anti-programmed death-1/anti-programed death ligand-1 therapies, and combination therapies after TACE failure/refractoriness. In this review, we summarize the up-to-date information about the outcomes of several subsequent treatment modalities after TACE failure/refractoriness.

Objective This study aims to compare the efficacy and safety of AngioJet rheolytic thrombectomy vs. catheter-directed thrombolysis in patients with acute lower extremity deep vein thrombosis. Methods Between the period of February 2015 and October 2016, 65 patients with documented acute lower extremity deep vein thrombosis were treated with catheter-directed intervention. These patients were divided into two groups: AngioJet group and catheter-directed thrombolysis group. Comparisons were made with regard to efficacy and safety between these two groups. Results In the AngioJet group, complete or partial thrombus removal was accomplished in 23 (72%) and 3 (9%) patients, respectively. In the catheter-directed thrombolysis group, complete or partial thrombus removal was accomplished in 27 (82%) patients and 1 (3%) patient, respectively. In the AngioJet group, the perimeter difference between the suffered limb and healthy one declined from 5.1 ± 2.3 cm to 1.4 ± 1.2 cm ( P < 0.05). In the catheter-directed thrombolysis group, the perimeter difference declined from 4.7 ± 1.6 cm to 1.5 ± 0.9 cm ( P < 0.05). The mean urokinase dose was 0.264 ± 0.135 million units in the AngioJet group and 1.869 ± 0.528 million units in the catheter-directed thrombolysis group ( P < 0.05). The duration of thrombolysis was 4.2 ± 1.7 h in the AngioJet group and 73.6 ± 18.3 h in the catheter-directed thrombolysis group ( P < 0.05). The occurrence of complications in these two groups was 19% and 18%, respectively (not significant). Conclusion AngioJet rheolytic thrombectomy is a new, safe and effective approach for treating acute lower extremity deep vein thrombosis. When compared to catheter-directed thrombolysis, this treatment provides similar success with lower urokinase dosage and shorter duration of thrombolysis.

A systematic review was conducted to provide an overview of the efficacy and safety of 125I irradiation stent placement for patients with hepatocellular carcinoma (HCC) and main portal vein tumor thrombosis (MPVTT). Six studies with 406 patients were included in the final analysis. The median overall survival for patients treated with 125I irradiation stent placement was 10.3 months. The most common radiation-related adverse event was leukopenia. The stent-related adverse events consisted of fever, abdominal pain, hemorrhage, and anorexia. No stent or seed migration was reported. Overall, the use of an 125I irradiation stent has the potential to act as an alternative therapy for patients with HCC with MPVTT.

To review the current status and ideal time interval of the combination therapy of transarterial chemoembolization (TACE) and local ablation for patients with HCCs. In recent years, local ablation has been proposed as an alternative curative treatment in the management of HCC. Additionally, many treatment options are available including TACE molecular targeted agents and immune checkpoint inhibitors. Similar overall survival rates and prognoses have been obtained with radiofrequency ablation (RFA) microwave ablation (MWA) and cryoablation for patients with HCCs up to 3 cm in diameter. Yet, MWA has shown superiority in treating large HCCs while cryoablation has several advantages compared with RFA or MWA. Furthermore, the treatment strategy of TACE combined with local ablation is widely accepted by many physicians in order to further increase the survival rate and improve the prognosis of patients with HCCs. However, the time interval between the two sessions of combination therapy remains uncertain in the current guidelines. Combination therapy of TACE and local ablation has advantages on survival and prognosis in patients with HCC compared with monotherapy. Good patient selection for the right modality needs to be carried out to guarantee the most efficacious treatment for HCC patients. Further studies are needed to find the ideal time interval between TACE and local ablation for HCC patients.

Purpose To construct the albumin-bilirubin (ALBI) grade and the Child-Turcotte-Pugh (CTP) score based on nomograms, as well as to develop an artificial neural network (ANN) to compare the prognostic performance of the 2 scores for hepatocellular carcinoma (HCC) that has undergone transarterial chemoembolization. Materials and Methods This multicentric retrospective study included patients with HCC who underwent transarterial chemoembolization monotherapy as an initial treatment at 4 institutions between January 2008 and December 2016. In the training cohort, significant risk factors associated with overall survival (OS) were identified by univariate and multivariate analyses. The prognostic nomograms and ANN were established and then validated in 2 validation cohorts. Results A total of 838 patients (548, 115, and 175 in the training cohort and validation cohorts 1 and 2, respectively) were included. The median OS was 10.4, 15.7, and 9.2 months in the training cohort and validation cohorts 1 and 2, respectively. In the training cohort, both ALBI grade and CTP score were identified as significant risk factors. The ALBI grade and CTP score based on nomograms were established separately and showed similar prognostic performance when assessed externally in validation cohorts (C-index in validation cohort 1: 0.823 vs 0.802, P = .417; in validation cohort 2: 0.716 vs 0.729, P = .793). ANN showed that ALBI grade had higher importance on survival prediction than CTP score. Conclusions ALBI grade performs at least no worse than CTP score regarding survival prediction for HCC receiving transarterial chemoembolization. Considering the easy application, ALBI grade has the potential to be regarded as an alternative to CTP score.

PurposeGiven that the novel coronavirus disease (COVID-19) pandemic has disrupted operations globally, an institution’s ability to repeat transarterial chemoembolization (TACE) for patients with hepatocellular carcinoma (HCC) has also been affected. The aim of this study was to evaluate the impact of the COVID-19 on the intervals and outcomes of TACE in HCC patients.Materials and MethodsThis retrospective study included 154 HCC patients who underwent follow-up after TACE treatment from January 2020 to March 2020 (n = 71, study group) and January 2019 to March 2019 (n = 83, control group) at two institutions in China. The endpoints included the follow-up interval and overall response rate (ORR). Multivariate logistic regression analyses were performed to identify independent risk factors for a worse ORR. The cut-off point was determined to divide follow-up durations into long- and short-intervals.ResultsThe median follow-up interval was 82.0 days (IQR, 61–109) in the study group, which was significantly longer than 66.0 days (IQR, 51–94) in the control group (P = 0.004). The ORR was 23.9 and 39.8% in the study and control group, respectively (P = 0.037). The cut-off value was 95 days. The grouping (OR, 2.402; 95% CI, 1.040–5.546; P = 0.040), long interval (OR, 2.573; 95% CI, 1.022–6.478; P = 0.045), and China liver cancer staging system (OR, 2.500; 95% CI, 1.797–3.480; P <0.001) were independent predictors for the efficacy of TACE treatment.ConclusionsThe COVID-19 pandemic causes a longer follow-up interval in general, which may further lead to a lower ORR in HCC patients. Those with a follow-up interval of >95 days tend to have a worse prognosis.

PURPOSE To investigate subclinical left atrial (LA) myocardial dysfunction in essential hypertension (EHT) patients by using volume-derived and two-dimensional strain. METHODS We enrolled in this study 51 normal subjects and 95 EHT patients. The LA volume-derived index was measured in apical 4- and 2-chamber views. LA strain and strain rate, reservoir, conduit, and booster pump functions were measured by two-dimensional speckle tracking echocardiography (STE). RESULTS LA ejection fraction (LAEF) and absolute strain-derived values were significantly lower in EHT patients than in controls. LAEF (total, passive), absolute values of LA strain (S-reservoir and S-conduit), and strain rate (Sr-reservoir and Sr-conduit) were significantly lower in EHT patients with left ventricular hypertrophy (LVH) than in patients without LVH and in controls. However, there were no significant difference in active LAEF or S-booster pump and Sr-booster pump functions between EHT patients without LVH and normal subjects. The areas under the curves of the combination of volume-derived values, LA strain, and strain rate were significantly higher than those of individual indices. CONCLUSION In our population, EHT patients showed impaired LA functions and greater stiffness than normal subjects. EHT patients with LVH showed greater impairment of LA reservoir and conduit functions than patients without LVH. EHT patients without LVH had normal LA booster pump function, which was impaired in patients with LVH. Volume-derived and 2D strain values could provide a sensitive and reproducible method for detecting subclinical LA myocardial dysfunction in EHT.

Hepatocellular carcinoma (HCC) is among the primary causes of cancer deaths globally. Despite efforts to understand liver cancer, its high morbidity and mortality remain high. Herein, we constructed two nomograms based on competing endogenous RNA (ceRNA) networks and invading immune cells to describe the molecular mechanisms along with the clinical prognosis of HCC patients. RNA maps of tumors and normal samples were downloaded from The Cancer Genome Atlas database. HTseq counts and fragments per megapons per thousand bases were read from 421 samples, including 371 tumor samples and 50 normal samples. We established a ceRNA network based on differential gene expression in normal versus tumor subjects. CIBERSORT was employed to differentiate 22 immune cell types according to tumor transcriptomes. Kaplan-Meier along with Cox proportional hazard analyses were employed to determine the prognosis-linked factors. Nomograms were constructed based on prognostic immune cells and ceRNAs. We employed Receiver operating characteristic (ROC) and calibration curve analyses to estimate these nomogram. The difference analysis found 2028 messenger RNAs (mRNAs), 128 micro RNAs (miRNAs), and 136 long non-coding RNAs (lncRNAs) to be significantly differentially expressed in tumor samples relative to normal samples. We set up a ceRNA network containing 21 protein-coding mRNAs, 12 miRNAs, and 3 lncRNAs. In Kaplan-Meier analysis, 21 of the 36 ceRNAs were considered significant. Of the 22 cell types, resting dendritic cell levels were markedly different in tumor samples versus normal controls. Calibration and ROC curve analysis of the ceRNA network, as well as immune infiltration of tumor showed restful accuracy (3-year survival area under curve (AUC): 0.691, 5-year survival AUC: 0.700; 3-year survival AUC: 0.674, 5-year survival AUC: 0.694). Our data suggest that Tregs, CD4 T cells, mast cells, SNHG1, HMMR and hsa-miR-421 are associated with HCC based on ceRNA immune cells co-expression patterns. On the basis of ceRNA network modeling and immune cell infiltration analysis, our study offers an effective bioinformatics strategy for studying HCC molecular mechanisms and prognosis.

Objectives The aim of this study was to determine whether global myocardial work (MW), derived from non-invasive left ventricle (LV) pressure-strain loops (PSL) at rest, could predict subclinical LV myocardial dysfunction in preserved left ventricular ejection fraction (LVEF) essential hypertension (EHT) patients. Methods A total of 105 untreated EHT patients and 55 normal controls were enrolled in this study. Apical 4-, 3- and 2-chamber views were acquired by two-dimensional echocardiography. The peak systolic myocardial layer-specific longitudinal strain (epimyocardial: GLSEpi; middle layer: GLSMid; and endomyocardial: GLSEndo), global myocardial work index (GWI), global constructive work (GCW), global wasted work (GWW), and myocardial work efficiency (GWE) were generated by speckle-tracking echocardiography (STE). Results The values of GLSEpi, GLSMid, and GLSEndo were significantly lower in EHT patients with LVH than in EHT patients without LVH and normal controls. GWW was significantly increased in EHT patients with LVH compared with without LVH and normal subjects, while GWE was significantly reduced in EHT patients with LVH compared with without LVH and normal subjects. ROC analysis showed that combined global MW values were a more sensitive predictor for detecting the accuracy of LV subclinical dysfunction in EHT patients than layer-specific GLS. Conclusion From the research, we conclude that global MW is more sensitive to layer-specific GLS in its ability to detect subclinical LV dysfunction even in EHT patients even without LVH.

Background: To investigate left atrial(LA) function in essential hypertension(EHT) patients by using volume-derived values, two-dimensional strain. Methods: 51 normal subjects and 95 EHT patients(without LVH: 50, and with LVH: 45) were enrolled for this research. LA Volume-derived index was measured in apical 4-, 2-chamber views by Simpson′s method. LA strain(S-reservoir, S-conduit, S-booster pump) and strain rate (SR-reservoir, SR-conduit, SR-booster pump), representing the reservoir, conduit and booster pump functions, respectively, were measured by two-dimensional speckle tracking echocardiography(STE).Results: Volume-derived values(contain Total LAEF, passive LAEF and active LAEF) and strain-derived values(S-reservoir, S-conduit, Sr-reservoir, Sr-conduit and Sr-booster pump) in EHT patients were significantly lower than normal subjects. Correlation test showed LA stiffness had a strong correlation with LA conduit function in EHT patients. The AUC values were higher for detection LA conduit function than LA reservoir and booster pump function in EHT patients. LA expansion index and LA stiffness also have the higher AUC with higher sensitivity and specificity values for detection the LA dysfunctions in EHT patients. Conclusions: In this study, we concluded that LA functions were damaged in EHT patients, which could be detect by LA volume-derived values and two-dimensional strain sensitively and reproductively. LA stiffness maybe a predictor for LV remodelling in EHT patients.

With the advance of imaging and puncture technology, the number of minimally invasive interventional treatments for pancreatic cancer is increasing. In this chapter, the adaptation certificate, operation technique, complications, and efficacy of various minimally invasive interventional treatments related to pancreatic cancer pain are introduced accordingly. Pain is the most common and serious clinical symptom of advanced pancreatic cancer, and most patients suffer from severe abdominal pain caused by cancer, including autonomic nerves, causing severe abdominal and back pain, which seriously affects the patient’s diet and sleep, accelerate physical consumption, and result in a series of adverse prognoses, where treatment is more difficult. The treatment of pancreatic cancer pain minimally invasive interventional treatment is an important part of pancreatic cancer treatment, which can improve the quality of life of patients and prolong survival.

Objective: To compare the outcomes of transarterial chemoembolization (TACE) combined with sorafenib versus TACE alone for treating patients with unresectable hepatocellular carcinoma (HCC). Methods: This retrospective analysis included all patients receiving either TACE plus sorafenib therapy or TACE alone for unresectable HCC between February 2008 and August 2015 at the First Affiliated Hospital of Soochow University, China. Propensity score matching (PSM) was carried out to reduce bias due to confounding variables. The primary outcome was overall survival (OS), calculated from the date of the first TACE treatment until the date of death of any cause. A multivariate Cox proportional hazards analysis was conducted to examine determinants of OS. Results: A total of 308 patients were included in the study: 61 receiving TACE plus sorafenib treatment and 247 receiving TACE monotherapy. The PSM cohort included 61 subjects receiving TACE plus sorafenib and 122 subjects receiving TACE alone. In the overall analysis that included all patients, the median OS in the combination group was significantly longer than that in the monotherapy group (29.0 ± 7.2 vs. 14.9 ± 1.1 months; P = 0.008). In the PCM cohort, the median OS was also significantly longer in the combination group (29.0 ± 7.2 vs. 14.9 ± 1.5 months; P = 0.018). Subgroup analysis revealed longer OS in patients receiving combination treatment in both the BCLC-B and BCLC-C subgroups (P < 0.05 for both). Multivariate analyses in the PSM cohort revealed that treatment methods (P = 0.003), number of nodules (P = 0.010), tumor size (P = 0.012), vascular invasion (P = 0.005), and number of TACE (P = 0.029) were independent prognostic factors of OS. The most common adverse events were hand-foot skin reaction (75.4%) and diarrhea (47.5%) in the combination group, and fatigue (19.0%) and liver dysfunction (18.2%) in the monotherapy group. There were no treatment-related deaths in either group. Conclusion: The combined use of TACE and sorafenib is generally well tolerated and could significantly increase OS of patients with unresectable HCC.

Objective To evaluate and compare the treatment efficacy and safety between catheter-directed thrombolysis monotherapy and catheter-directed thrombolysis combined with percutaneous mechanical thrombectomy for patients with subacute iliofemoral deep vein thrombosis. Methods We conducted a retrospective analysis of a total of 74 subacute iliofemoral deep vein thrombosis patients who underwent catheter-directed thrombolysis with and without percutaneous mechanical thrombectomy. Patients treated with catheter-directed thrombolysis combined with percutaneous mechanical thrombectomy (percutaneous mechanical thrombectomy group, n = 30) or catheter-directed thrombolysis monotherapy (catheter-directed thrombolysis group, n = 44) were included. The primary endpoints were the clinical efficacy rate of thrombolysis, primary patency, and the incidence of post-thrombotic syndrome (at 12 months diagnosed according to the original Villalta score criteria. Secondary endpoints were the total urokinase dose, the thrombolysis time, the detumescence rate and complications. Results The percentage of successful thrombolysis for percutaneous mechanical thrombectomy group was higher than that for catheter-directed thrombolysis group ( P = 0.045). At the 12-month follow-up, there was no difference in the primary patency ( P > 0.05) or the incidence of post-thrombotic syndrome ( P = 0.36). Percutaneous mechanical thrombectomy group had significant advantages in reducing urokinase doses and thrombolysis times compared with catheter-directed thrombolysis group for patients with thrombus clearance levels II and III ( P Conclusion Catheter-directed thrombolysis combined with percutaneous mechanical thrombectomy performs better in removing vein thrombi, reducing urokinase doses, and shortening thrombolysis times.

Patients with HCC receiving TACE have various clinical outcomes. Several prognostic models have been proposed to predict clinical outcomes for patients with hepatocellular carcinomas (HCC) undergoing transarterial chemoembolization (TACE), but establishing an accurate prognostic model remains necessary. We aimed to develop a radiomics signature from pretreatment CT to establish a combined radiomics-clinic (CRC) model to predict survival for these patients. We compared this CRC model to the existing prognostic models in predicting patient survival. This retrospective study included multicenter data from 162 treatment-naïve patients with unresectable HCC undergoing TACE as an initial treatment from January 2007 and March 2017. We randomly allocated patients to a training cohort (n = 108) and a testing cohort (n = 54). Radiomics features were extracted from intra- and peritumoral regions on both the arterial phase and portal venous phase CT images. A radiomics signature (Rad-signature) for survival was constructed using the least absolute shrinkage and selection operator method in the training cohort. We used univariate and multivariate Cox regressions to identify associations between the Rad- signature and clinical factors of survival. From these, a CRC model was developed, validated, and further compared with previously published prognostic models including four-and-seven criteria, six-and-twelve score, hepatoma arterial-embolization prognostic scores, and albumin-bilirubin grade. The CRC model incorporated two variables: The Rad-signature (composed of features extracted from intra- and peritumoral regions on the arterial phase and portal venous phase) and tumor number. The CRC model performed better than the other seven well-recognized prognostic models, with concordance indices of 0.73 [95% confidence interval (CI) 0.68–0.79] and 0.70 [95% CI 0.62–0.82] in the training and testing cohorts, respectively. Among the seven models tested, the six-and-12 score and four-and-seven criteria performed better than the other models, with C-indices of 0.64 [95% CI 0.58–0.70] and 0.65 [95% CI 0.55–0.75] in the testing cohort, respectively. The CT radiomics signature represents an independent biomarker of survival in patients with HCC undergoing TACE, and the CRC model displayed improved predictive performance.

Purpose To assess the role of epithelial cell adhesion molecule (EpCAM)–positive circulating tumor cell (CTC) count in predicting survival outcomes of transcatheter arterial chemoembolization in patients with unresectable hepatocellular carcinoma (HCC). Materials and Methods EpCAM-positive CTC counts were prospectively determined via CellSearch in peripheral blood of 97 patients with unresectable HCC treated with chemoembolization. The impact of each CTC cutoff point on overall survival (OS) was evaluated by univariate Cox regression analysis. Based on hazard ratio, patients were divided into 3 groups with low (CTC count 0/1), moderate (CTC count 2–5), and high (CTC count ≥ 6) levels. Correlation of CTC counts with survival was assessed by Cox proportional-hazards model. Results Eighty-nine patients met inclusion criteria and were enrolled. On multivariate Cox regression analysis, CTC count was found to be an independent predictor of OS (P = .049) and progression-free survival (PFS; P = .007) in patients treated with chemoembolization. After adjustment for confounding factors, mortality risks in the high- and moderate-level groups were 2.819 times (95% confidence interval [CI], 1.218–6.526; P = .016) and 1.301 times (95% CI, 0.630–2.685; P = .477) greater, respectively, than in the low-level group. The risk of progression was 3.705 fold higher in the high-level group (95% CI, 1.628–8.433; P = .002) and 1.648 fold higher in the moderate-level group (95% CI, 0.843–3.223; P = .144) vs the low-level group. Conclusions High EpCAM-positive CTC count predicts poor survival of patients with unresectable HCC treated with chemoembolization.

Purpose The aim of this paper is to provide a novel, publicly available standard image dataset with a useful evaluation framework for assessing nonrigid two-/three-dimensional (2D/3D) registration algorithms. Acquisition and validation methods A pig lung model was used to obtain the image dataset. Inflated with different amounts of oxygen, a sequence of 3D volume data was acquired with computed tomography (CT), which ideally simulated different respiratory phases. With the model inflated and kept in certain states, 3D CT, 2D CT scout image and 2D x-ray were acquired for the same respiratory phases, making them suitable to establish the evaluation dataset for 2D/3D registration algorithms. A total of 120 well-distributed landmarks in every 3D volume were manually annotated and checked by several radiologists using semi-automatic software to generate the dataset. Data format and usage notes All 3D image data were stored in both DICOM and ITK Meta format, and 2D image data were stored in DICOM format. A total of 120 landmarks were manually annotated for each 3D image. Among these landmarks, eight landmarks located on large branch of the bronchial tree were also annotated in 2D images. The landmark coordinates were stored in a text file. The detailed usage including a standard evaluation framework for the proposed dataset is also provided. The dataset can be downloaded from the Zenodo repository (https://doi.org/10.5281/zenodo.997887). Potential applications Our standard dataset was acquired with advanced clinical imaging devices and is quite suitable for quantitatively evaluating state-of-art, nonrigid 2D/3D registration algorithms.

Epidermal growth factor-like domain multiple 7 (EGFL7) is an important sport stimulating factor and motility related factors significantly enhanced the tumor cell metastasis and overexpressed in many cancers, including hepatocellular carcinoma (HCC), associated with tumorigenesis. However, the molecular mechanism by which EGFL7 regulates HCC cell proliferation and apoptosis and the correlation between EGFL7 and cyclin-dependent kinases regulatory subunit 2 (CKS2), which is essential for biological function, have not fully explained. In this study, EGFL7 and CKS2 expression in patients with HCC was measured by real-time polymerase chain reaction and immunohistochemistry. After HCC cells respectively transfected with pLKO.1-EGFL7-shRNA, pLVX-Puro-EGFL7 recombined vector or CKS2 small interfering RNA, cell counting kit-8 and flow cytometry was performed to examine the cell proliferation and apoptosis, respectively, and the expression of β-catenin, CKS2, CDK2, and cleaved caspase-3 was measured by Western blot analysis. We found that EGFL7 and CKS2 were overexpressed in HCC tissues and a positive correlation was found between them. EGFL7 knockdown markedly inhibited proliferation and promoted apoptosis of HCC cells, along with decreased expression of CKS2 and CDK2, but increased cleaved caspase-3 expression, while EGFL7 overexpression showed an opposite effect. EGFL7 silencing in nude mice also showed decreased tumor growth and altered protein expression similar to its effect in HCC cells in vitro. Importantly, CKS2 silencing significantly inhibited EGFL7-induced HCC cell proliferation and protein expression, and Wnt/β-catenin signaling pathway inhibitor IWR-1-endo significantly inhibited CKS2 expression in HCC cells. Taken together, EGFL7 promotes HCC cell proliferation and inhibits cell apoptosis through increasing CKS2 expression by activating Wnt/β-catenin signaling.

We aimed to validate the performance of the hepatitis B-based Hong Kong Liver Cancer (HKLC) staging system compared with the Barcelona Clinic Liver Cancer (BCLC) staging system in Chinese hepatocellular carcinoma (HCC) patients treated with conventional transarterial chemoembolization (TACE) as the initial treatment. The study was approved by the Institutional Review Boards at all participating centers. This retrospective study included 715 patients with HCC who underwent TACE as the initial treatment between January 2008 and December 2016 at three Chinese institutions. All of the patients calculated HCC stage using 5-substage HKLC (HKLC-5), 9-substage HKLC (HKLC-9), and the BCLC system. Based on overall survival (OS), these three staging systems’ performance on treatment outcome prediction were compared using C statistic, Akaike information criterion (AIC), area under the receiver operating characteristic curve (AUC), linear trend Chi-square, likelihood ratio Chi-square, and calibration plots, respectively. The median OS was 10.1 months. Compared with the BCLC system, the HKLC system, especially HKLC-9, showed better performance on survival prediction (HKLC-9: C = 0.689, AIC = 6646.162; HKLC-5: C = 0.683, AIC = 6662.663; BCLC: C = 0.680, AIC = 6654.146), homogeneity (likelihood ratio Chi-square: HKLC-9 = 232.38, HKLC-5 = 215.87, and BCLC = 224.39, P

Background To investigate the safety and effectiveness of Fuaile medical adhesive (FAL) with superselective catheterization in endovascular embolotherapy for the treatment of gastrointestinal hemorrhage (GIH) that was unresponsive to internal medicine treatment and gastroscopy management. Methods A total of 25 patients with GIH, confirmed using angiography but with failed results after internal medicine treatment or gastroscopy were retrospectively analyzed. A mixture of lipiodol and FAL (1:1) was used to embolize the bleeding vessels. In the follow-up, the operation time, FAL amount, technical success rate, clinical success rate, postoperative complications, and survival conditions were compared and analyzed. Results Among the 25 patients with GIH, FAL was applied alone in 23 patients and microcoil combined with FAL was applied in two patients. Hemostasis was successfully achieved in all patients. Two patients treated with embolotherapy experienced relapse of bleeding within 30 days but achieved successful hemostasis with FAL. Four patients died during follow-up: three patients died of advanced cancer and one patient died of severe infection induced by necrotizing pancreatitis. Three patients developed postoperative intestinal ischemic symptoms, which resolved spontaneously in two patients. In one patient, abdominal pain progressively aggravated. This patient underwent surgical resection, which confirmed the presence of colonic neoplasms. The intraoperative view revealed obvious ischemia of the local normal bowel near the tumor; however, the patient finally recovered and was discharged after surgery. The remaining patients exhibited good survival during the postoperative follow-up. Conclusion FAL embolotherapy has a high success rate for arterial GIH that was unresponsive to internal medicine treatment and gastroscopy management, with low postoperative rates of bleeding and complications; thus, this method has a high cost-efficacy.

Background & Aims Placement of an irradiation stent has been demonstrated to offer longer patency and survival than an uncovered self-expandable metallic stent (SEMS) in patients with unresectable malignant biliary obstruction (MBO). We aim to further assess the efficacy of an irradiation stent compared to an uncovered SEMS in those patients. Methods We performed a randomized, open-label trial of participants with unresectable MBO at 20 centers in China. A total of 328 participants were allocated in parallel to the irradiation stent group (ISG) or the uncovered SEMS group (USG). Endpoints included stent patency (primary), technical success, relief of jaundice, overall survival, and complications. Results The first quartile stent patency time (when 25% of the patients experienced stent restenosis) was 212 days for the ISG and 104 days for the USG. Irradiation stents were significantly associated with a decrease in the rate of stent restenosis (9% vs. 15% at 90 days; 16% vs. 27% at 180 days; 21% vs. 33% at 360 days; p = 0.010). Patients in the ISG obtained longer survival time (median 202 days vs. 140 days; p = 0.020). No significant results were observed in technical success rate (93% vs. 95%; p = 0.499), relief of jaundice (85% vs. 80%; p = 0.308), and the incidence of grade 3 and 4 complications (8.5% vs. 7.9%; p = 0.841). Conclusions Insertion of irradiation stents instead of uncovered SEMS could improve patency and overall survival in patients with unresectable MBO. Lay summary For patients with unresectable malignant biliary obstruction (MBO), placement of a self-expandable metallic stent (SEMS) is a recommended palliative modality to relieve pruritus, cholangitis, pain, and jaundice. However, restenosis is a main pitfall after stent placement. Data from this first multicenter randomized controlled trial showed that insertion of an irradiation stent provided longer patency and better survival than a conventional metal stent.

Background: Transarterial chemoembolization (TACE) may not be repeated “on-demand” timely for hepatocellular carcinoma (HCC) patients in the era of the novel coronavirus disease (COVID-19). We aim to evaluate the impact of the COVID-19 pandemic on the intervals and outcomes of TACE in HCC patients. Methods: This retrospective study included HCC patients who underwent TACE from Jan 1, 2020 to March 31, 2020 (study group) and Jan 1, 2019 to Mar 31, 2019 (control group) at two institutions in China. The endpoints included the TACE interval and the overall response rate (ORR). Uni- and multivariate logistic analyses were performed to identify independent risk factors associated with a worse ORR. The cut-off point was determined to divide repeated TACE time into long- and short- intervals. Findings: 154 patients (71 in the study group, 83 in the control group) were enrolled. The median TACE interval in the study group was 82·0 days (IQR, 61–109), longer than 66·0 days (IQR, 51–94) in the control group (p=0·004). The ORR was 23·9% in the study group, while 39·8% in the control group (p=0·037). The cut-off value was 95 days. The group (OR, 2·402; 95% CI, 1·040–5·546; p=0·040), the long interval (OR, 2·573; 95% CI, 1·022–6·478; p=0·045), and the stage system (OR, 2·500; 95% CI, 1·797–3·480; p
