Abstract
Purpose We aimed to develop a prognostic nomogram utilizing preoperative serum prealbumin levels to predict the overall survival (OS) in patients undergoing transarterial chemoembolization (TACE) for unresectable hepatocellular carcinoma (HCC). Patients and Methods A total of 768 individuals with unresectable HCC who underwent TACE at three medical facilities in Suzhou between January 2007 December 2018 were included. The patient cohort was assigned to a training set (n = 461) and a validation set (n = 307). Cox regression analysis identified independent prognostic factors, which were then used to construct a prognostic nomogram. Internal validation was performed in the testing group, and its effectiveness and capability were evaluated with reference to the concordance index (C-index), area under the curve (AUC), calibration curve, and decision curve analysis (DCA). Results Independent risk factors identified through Cox regression analyses included the BCLC stage, cirrhosis, invasion, tumor number, preoperative serum PALB, performance status (PS), and tumor size. The nomogram demonstrated a C-index of 0.734 (95% confidence interval (CI): 0.710-0.758) in the training set and 0.717 (95% CI: 0.678-0.756) in the validation set, indicating strong discriminatory ability. The nomogram also demonstrated favorable discriminatory performance with AUC values of 0.873, 0.820, and 0.833 for 1-, 2-, and 3-year OS, respectively, in the training set, and 0.854, 0.765, and 0.724 in the validation set. The AUC value of the nomogram (0.843) was significantly higher than that of the four conventional staging systems. Moreover, calibration graphs confirmed a strong concordance between the predicted and observed results. Furthermore, DCA underscored the significant clinical utility of the nomogram. Additionally, the low-risk group exhibited considerably superior rates of survival compared to the high-risk group. Conclusion The developed nomogram demonstrated excellent prognostic capability, which served as a valuable tool for personalized clinical decision-making for patients with HCC.

Abstract
Purpose To retrospectively evaluate and compare treatment effectiveness and safety between transarterial chemoembolization (TACE) combined with molecularly targeted agents plus immune checkpoint inhibitors (TACE+T+I) and TACE combined with molecularly targeted agents (TACE+T) for unresectable hepatocellular carcinoma (uHCC). Methods We retrospectively analyzed the data of patients with unresectable HCC from January 2018 to June 2022. The patients were screened based on the inclusion criteria and were divided into the triple combination group (TACE+T+I) and the double combination group (TACE+T). The primary outcomes were overall survival (OS), progression-free survival (PFS), and adverse events (AEs). The secondary outcomes were objective response rate (ORR) and disease control rate (DCR). Risk factors associated with PFS and OS were determined by Cox regression analysis. Results A total of 87 patients were enrolled in this study, including 42 patients in the TACE+T+I group and 45 patients in the TACE+T group. Over a median follow-up of 29.00 and 26.70 months, patients who received TACE+T+I therapy achieved a significantly longer median OS (24.00 vs. 21.40 months, p = 0.007) and median PFS (9.70 vs. 7.00 months, p = 0.017); no grade 4 AEs or treatment-related death occurred in the two groups. Grade 3 AEs attributed to systemic agents in the two groups showed no significant difference (19.0% vs. 15.6%, p = 0.667). Patients in the TACE+T+I group demonstrated better tumor response when compared with patients in the TACE+T group, with an ORR of 52.4% vs. 17.8% (p = 0.001). No significant difference was observed in DCR between the two groups (83.3% vs. 77.8%, p = 0.514). Cox regression analysis showed that only the treatment method was an independent factor of OS, and both age and treatment method were independent factors related to PFS. Conclusion Compared with TACE plus molecularly targeted agents (TACE+T), the triple therapy (TACE+T+I) could improve survival and tumor response in unresectable HCC with manageable toxicities.

Abstract
Background Recent studies have shown that inflammatory indicators are closely related to the prognosis of patients with hepatocellular carcinoma, and they can serve as powerful indices for predicting recurrence and survival time after treatment. However, the predictive ability of inflammatory indicators has not been systematically studied in patients receiving transarterial chemoembolization (TACE). Therefore, the objective of this research was to determine the predictive value of preoperative inflammatory indicators for unresectable hepatocellular carcinoma treated with TACE. Methods Our retrospective research involved 381 treatment-naïve patients in 3 institutions, including the First Affiliated Hospital of Soochow University, Nantong First People's Hospital, and Nantong Tumor Hospital, from January 2007 to December 2020 that received TACE as initial treatment. Relevant data of patients were collected from the electronic medical record database, and the recurrence and survival time of patients after treatment were followed up. Least absolute shrinkage and selection operator (LASSO) algorithm was used to compress and screen the variables. We utilized Cox regression to determine the independent factors associated with patient outcomes and constructed a nomogram based on multivariate results. Finally, the nomogram was verified from discriminability, calibration ability, and practical applicability. Results Multivariate analysis revealed that the levels of aspartate aminotransferase-to-platelet ratio index (APRI) and lymphocyte count were independent influential indicators for overall survival (OS), whereas the levels of platelet-to-lymphocyte ratio (PLR) was an independent influential index for progression. Nomograms exhibited an excellent concordance index (C-index), in the nomogram of OS, the C-index was 0.753 and 0.755 in training and validation cohort, respectively; and in the nomogram of progression, the C-index was 0.781 and 0.700, respectively. The time-dependent C-index, time-dependent receiver operating characteristic (ROC), and time-dependent area under the curve (AUC) of the nomogram all exhibited ideal discrimination ability. Calibration curves significantly coincided with the standard lines, which indicated that the nomogram had high stability and low degree of over-fitting. Decision curve analysis revealed a wider range of threshold probabilities and could augment net benefits. The Kaplan-Meier curves for risk stratification indicated that the prognosis of patients varied significantly between risk categories (P < .0001). Conclusions The developed prognostic nomograms based on preoperative inflammatory indicators revealed high predictive accuracy for survival and recurrence. It can be a valuable clinical instrument for guiding individualized treatment and predicting prognosis.

Abstract
Objective This study aimed to investigate the cutoff value of quantitative and volumetric response evaluation criteria for patients with hepatocellular carcinoma (HCC) after transarterial chemoembolization (TACE) and compare the performance of the modified criteria to one-dimensional criteria in survival prediction. Methods A retrospective single-center study was performed for treatment-naive patients with HCC who underwent initial TACE between June 2015 and June 2019. Treatment response assessment was performed after the first observation by contrast CT or MRI, with the measurement of diameters by modified Response Evaluation Criteria in Solid Tumors (mRECIST) and volumes by quantitative European Association for Study of the Liver (qEASL). Overall survival (OS) was the primary endpoint of this study. The new cutoff value for volumetric response evaluation criteria was created using restricted cubic splines. The performance of modified qEASL (mqEASL, with the new cutoff value) and mRECIST on survival prediction was compared by Cox regression models in internal and external validation. Results A total of 129 patients (mean age, 60 years ± 11 [standard deviation]; 111 men) were included and divided into training (n=90) and validation (n=39) cohorts. The cutoff value for the viable volume reduction was set at 57.0%. The mqEASL enabled separation of non-responders and responders in terms of median OS (p<0.001), 11.2 months (95% CI, 8.5-17.2 months) vs. 31.5 months (95% CI, 25.5-44.0 months). Two multivariate models were developed with independent prognostic factors (tumor response, metastasis, portal vein tumor thrombus, and subsequent treatment) to predict OS. Model 2 (for mqEASL) had a greater Harrel's C index, higher time-dependent area under the receiving operator characteristic curve (AUROC), and more precise calibration on 6-month survival rates than Model 1 (for mRECIST). Conclusions With the modified cutoff value, the quantitative and volumetric response of HCC patients to TACE becomes a precise predictor of overall survival. Further studies are needed to verify this modification before application in clinical practice.

Abstract
Objective To compare the diagnostic efficacy of serological indices and ultrasound (US) variables in hepatitis B virus (HBV) liver fibrosis staging using random forest algorithm (RFA) and traditional methods. Methods The demographic and serological indices and US variables of patients with HBV liver fibrosis were retrospectively collected and divided into serology group, US group, and serology + US group according to the research content. RFA was used for training and validation. The diagnostic efficacy was compared to logistic regression analysis (LRA) and APRI and FIB-4 indices. Results For the serology group, the diagnostic performance of RFA was significantly higher than that of APRI and FIB-4 indices. The diagnostic accuracy of RFA in the four classifications (S0S1/S2/S3/S4) of the hepatic fibrosis stage was 79.17%. The diagnostic accuracy for significant fibrosis (≥S2), advanced fibrosis (≥S3), and cirrhosis (S4) was 87.99%, 90.69%, and 92.40%, respectively. The area under the curve (AUC) values were 0.945, 0.959, and 0.951, respectively. For the US group, there was no significant difference in diagnostic performance between RFA and LRA. The diagnostic performance of RFA in the serology + US group was significantly better than that of LRA. The diagnostic accuracy of the four classifications (S0S1/S2/S3/S4) of the hepatic fibrosis stage was 77.21%. The diagnostic accuracy for significant fibrosis (≥S2), advanced fibrosis (≥S3), and cirrhosis (S4) was 87.50%, 90.93%, and 93.38%, respectively. The AUC values were 0.948, 0.959, and 0.962, respectively. Conclusion RFA can significantly improve the diagnostic performance of HBV liver fibrosis staging. RFA based on serological indices has a good ability to predict liver fibrosis staging. RFA can help clinicians accurately judge liver fibrosis staging and reduce unnecessary biopsies.

Abstract
Background: Residual viable tumor cells after ablation at the tumor periphery serve as the source for tumor recurrence, leading to treatment failure. Purpose: To develop a novel three-dimensional (3D) multi-modal perfusion-thermal electrode system completely eradicating medium-to-large malignancies. Materials and Methods: This study included five steps: (i) design of the new system; (ii) production of the new system; (iii) ex vivo evaluation of its perfusion-thermal functions; (iv) mathematic modeling and computer simulation to confirm the optimal temperature profiles during the thermal ablation process, and; (v) in vivo technical validation using five living rabbits with orthotopic liver tumors. Results: In ex vivo experiments, gross pathology and optical imaging demonstrated the successful spherical distribution/deposition of motexafin gadolinium administered through the new electrode, with a temperature gradient from the electrode core at 80 °C to its periphery at 42 °C. An excellent repeatable correlation of temperature profiles at varying spots, from the center to periphery of the liver tumor, was found between the mathematic simulation and actual animal tumor models (Pearson coefficient ≥0.977). For in vivo validation, indocyanine green (ICG) was directly delivered into the peritumoral zones during simultaneous generation of central tumoral lethal radiofrequency (RF) heat (>60 °C) and peritumoral sublethal RF hyperthermia (<60 °C). Both optical imaging and fluorescent microscopy confirmed successful peritumoral ICG distribution/deposition with increased heat shock protein 70 expression. Conclusion: This new 3D, perfusion-thermal electrode system provided the evidence on the potential to enable simultaneous delivery of therapeutic agents and RF hyperthermia into the difficult-to-treat peritumoral zones, creating a new strategy to address the critical limitation, i.e., the high incidence of residual and recurrent tumor following thermal ablation of unresectable medium-to-large and irregular tumors.

Abstract
Transarterial chemoembolization (TACE) with free doxorubicin-lipiodol emulsions (free DOX/L) is a favored clinical treatment for advanced hepatocellular carcinoma (HCC) patients ineligible for radical therapies; however, its inferior colloidal stability not only greatly reduces its tumor retention but also hastens drug release into blood circulation, leading to suboptimal clinical outcomes. Here, we find that disulfide-crosslinked polymersomes carrying doxorubicin (Ps-DOX) form super-stable and homogenous water-in-oil microemulsions with lipiodol (Ps-DOX/L). Ps-DOX/L microemulsions had tunable sizes ranging from 14 to 44 μm depending on the amount of Ps-DOX, were stable over 2 months storage as well as centrifugation, and exhibited nearly zero-order DOX release within 15 days. Of note, Ps-DOX induced 2.3-13.4 fold better inhibitory activity in all tested rat, murine and human liver tumor cells than free DOX likely due to its efficient redox-triggered intracellular drug release. Interestingly, transarterial administration of Ps-DOX/L microemulsions in orthotopic rat N1S1 syngeneic HCC model showed minimal systemic DOX exposure, high and long hepatic DOX retention, complete tumor elimination, effective inhibition of angiogenesis, and depleted adverse effects, significantly outperforming clinically used free DOX/L emulsions. This smart polymersome stabilization of doxorubicin-lipiodol microemulsions provides a novel TACE strategy for advanced tumors.

Abstract
PURPOSE To evaluate the efficiency of radiomics signatures in predicting the response of transarterial chemoembolization (TACE) therapy based on preoperative contrast-enhanced computed tomography (CECT). MATERIALS This study consisted of 111 patients with intermediate-stage hepatocellular carcinoma who underwent CECT at both the arterial phase (AP) and venous phase (VP) before and after TACE. According to mRECIST 1.1, patients were divided into an objective-response group (n = 38) and a non-response group (n = 73). Among them, 79 patients were assigned as the training dataset, and the remaining 32 cases were assigned as the test dataset. METHODS Radiomics features were extracted from CECT images. Two feature ranking methods and three classifiers were used to find the best single-phase radiomics signatures for both AP and VP on the training set. Meanwhile, multi-phase radiomics signatures were built upon integration of images from two CECT phases by decision-level fusion and feature-level fusion. Finally, multivariable logistic regression was used to develop a nomogram by combining radiomics signatures and clinic-radiologic characteristics. The prediction performance was evaluated by AUC on the test dataset. RESULTS The multi-phase radiomics signature (AUC = 0.883) performed better in predicting TACE therapy response compared to the best single-phase radiomics signature (AUC = 0.861). The nomogram (AUC = 0.913) showed better performance than any radiomics signatures. CONCLUSION The radiomics signatures and nomogram were developed and validated for predicting responses to TACE therapy, and the radiomics model may play a positive role in identifying patients who may benefit from TACE therapy in clinical practice.

Abstract
Exosomes are extracellular vesicles with relatively specific expression of CD63 transmembrane protein. In this study, We designed and constructed a multisite-targeting polymer which has both fluorescence and targeting recognition. It can bond to the hydrophilic group of CD63 by connecting with hydrogen. The chemical structure and the ability to combine with CD63 of fluorescent monomer and polymer were characterized and confirmed by FTIR and 1H NMR. MTT assay was performed to detect the cytotoxicity and biocompatibility of this polymer. Then we found the cell viability was 80.64% and the hemolysis rate of erythrocyte was only 0.101% even at F concentration of 20 µM. In vitro, the proposed polymer showed better ability to enter cells after linking exosomes via CD63; in vivo, it showed the ability to bind stably to exosomes and target tumor implants.

Abstract
AIM To investigate the types, associated anomalies and postnatal outcomes of fetal hepatic venous system (HVS) variants by ultrasound in China. MATERIAL AND METHODS A large-scale and prospective investigation of HVS variants for low-risk singleton pregnant women was performed in three academic tertiary referral care centers in China. Ultrasound imaging wasused for the identification and follow-up of anatomical variants. Follow-up was conducted once every four weeks prenatally and every two months postnatally, mainly concerned on the adverse events that may appear. RESULTS There were 20848 cases with anatomical variants of fetal HVS identified from 46179 candidates during the study period. Following the anatomical position of variants occurring, four main divisions were present: main portal vein variants (17.9%), intrahepatic portal vein variants (21.30%), intrahepatic persistent right umbilical vein (0.27%) and hepatic vein variants (5.67%). In the fetal period, the pregnancy of all cases was normally continued, except that the pregnancy of two cases, which were associated with multiple anomalies and were terminated by their parents. After birth, approximately 99.47% of the cases with isolated variants orbeing associated no clinic significant anomalies were normally alive. Approximately 0.50% cases were associated with simple ventricular septum defect or tetralogy of Fallot and further treatment was needed. CONCLUSION The anatomical variants of fetal HVS may appear as numerical, morphological or positional variants of MPV, intrahepatic PV branches, intrahepatic PRUV and HVs. The majority of cases are isolated or their associated anomalies are not clinically significant and have normal lifeafter birth.

Abstract
OBJECTIVES The study aimed to evaluate the association of dietary iron intake with incident dementia and brain iron deposition. DESIGN/SETTING/PARTICIPANTS We included dementia-free participants from the UK Biobank who completed at least one 24-hour dietary recall at study baseline (2009-2012) and were followed up to 2021. Incident dementia was determined through linkage to medical records and death registries. Brain MRI was conducted in a subgroup of participants since 2014, with T2* measurements being used as indicators of brain iron deposition. MEASUREMENTS Cox proportional hazard models were used to assess the associations of high (top quintile) and low (bottom quintile) versus medium (quintile 2 to 4) level of dietary iron intake with incident dementia, respectively. Linear regression was applied to assess the relations between dietary iron intake and brain T2* measurements. RESULTS During follow-up (mean = 9.5 years), a total of 1,454 participants (650 women and 804 men) developed dementia among 191,694 participants (55.0% female; mean age, 56.2 years). When adjusted for sociodemographic, lifestyle, and other dietary factors, participants with low dietary iron intake (< 10.05 mg/day) had a significantly higher dementia risk (hazard ratio [HR], 1.50, 95% confidence interval [CI], 1.19-1.89), while the relation for high intake (> 16.92 mg/day) was non-significant (HR, 1.16, 95% CI, 0.92-1.46). A significant gender difference (P-interaction < 0.001) was observed, with a U-shaped association in male participants (HR for low vs. medium, 1.56, 95% CI, 1.14-2.13; HR for high vs. medium, 1.39, 95% CI, 1.03 - 1.88; P-nonlinearity < 0.001) and no significant association in females, regardless of their menopause status. In general, dietary iron intake was not related to T2* measurements of iron deposition in most brain regions. CONCLUSION Our findings suggested a U-shape relationship between dietary iron intake and risk of dementia among males, but not females.

Abstract
BACKGROUND AND OBJECTIVE The influence of cerebral large artery stenosis (CLAS) on ischemic leukoaraiosis (LA) remains elusive. Based on the proposed stages of the preinfarction period, this study aimed to adopt the staging system to assess the correlation between ischemic LA and CLAS. MATERIALS AND METHODS Patients with unilateral CLAS ≥50% and without cerebral stroke were screened. The severity and distribution of stenosis were evaluated on computed tomography angiography images. The degree of regional cerebral perfusion was rated according to the stages of preinfarction period: 0=normal, 1=stage Ia, 2=stage Ib, 3=stage IIa, 4=stage IIb. Stage I included stage Ia and stage Ib. Stage II included stage IIa and stage IIb. LA was scored with Fazakas scale on T2-weighted image and/or fluid-attenuated inversion recovery sequences. RESULTS The cohort consisted of 212 patients (mean age, 66.89±11.39 y), including 145 (68.40%) males. CLAS severity and distribution did not differ between patients with and without LA (P>0.05). Normal, stage I, and stage II had significantly different incidences of LA and hemispheric LA scores in the left and right hemispheres (P<0.05). The degree of regional cerebral perfusion was independently associated with LA in the left (P=0.0094) and right hemispheres (P=0.0091). CONCLUSIONS Ischemic LA is not directly related to CLAS but is independently associated with the degree of CLAS-induced cerebral hypoperfusion. The stages of the preinfarction period are helpful in identifying people at high risk of LA progression.

Abstract
PURPOSE 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. MATERIALS AND METHODS 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. RESULTS 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 < 0.001) and 85.7% versus 32.0% (P < 0.001), respectively. Median OS in the combination group (9.8 months) was longer than in the TACE group (5.2 months) (P = 0.024). Multivariate analysis revealed that, compared with the TACE group, the mortality risk in the combination group significantly decreased (hazard ratio: 0.444; P = 0.020). CONCLUSION Integrated I-125 seed implantation combined with TACE is a safe and effective treatment for HCC with MPVTT. LEVEL OF EVIDENCE Level 3, Non-randomized controlled cohort/follow-up study.

Abstract
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.

Abstract
The G protein-coupled receptors (GPRs) have been shown to regulate several cancer related processes. The aberrant expression of GPRs has been linked to the development of several cancers. The present study was designed to examine the expression and decipher the role of GPR15 in the development of human colorectal cancer. The results revealed GPR15 to be significantly (P < 0.05) upregulated in colorectal cancer cells. The silencing of GPR15 inhibited the growth of the colorectal cancer cells via induction of apoptosis. Induction of apoptosis in colorectal cancer cells was associated increase in Bax and decrease in Bcl-2 expression. The silencing of GPR-15 also caused a significant (P < 0.05) decline in the migration and invasion of the colorectal cancer cells. Bioinformatic analysis and luciferase assay revealed that the expression of GPR15 to be post-transcriptionally regulated by microRNA-1225 (miR-1225). The expression of miR-1225 was found to significantly (P < 0.05) downregulated in colorectal cancer cells and its overexpression caused suppression of GPR15 and inhibited the proliferation of the colorectal cancer cells. Nonetheless, overexpression of GPR15 could avoid the growth inhibitory effects of miR-1225. The results suggest that the GPR15/miR-1225 axis play an important role in the development of colon rectal cancer and exhibit therapeutic implications for its treatment.

Abstract
Patients who are unsuitable for chemoembolization could progress with extrahepatic spread or vascular invasion after initial chemoembolization monotherapy. A radiomics signature based on the machine learning algorithm was identified. The signature combined with clinicoradiologicial predictors could predict TACE-unsuitable patients. The combined model showed improved predictive performance compared with the model without radiomics signature. The combined model could stratify patients into three strata with a low, intermediate, or high risk in training and external testing sets.
Introduction Due to the high heterogeneity of hepatocellular carcinoma (HCC), patients with non-advanced disease who are unsuitable for initial transarterial chemoembolization (TACE) monotherapy may have the potential to develop extrahepatic spread or vascular invasion. We aimed to develop and independently validate a radiomics-based model for predicting which patients will develop extrahepatic spread or vascular invasion after initial TACE monotherapy (EVIT). Materials and methods This retrospective study included 256 HCC patients (training set: n = 136; testing set: n = 120) who underwent TACE as initial therapy between April 2007 and June 2018. Clinicoradiological predictors were selected using multivariate logistic regression and a clinicoradiological model was constructed. The radiomic features were extracted from contrast-enhanced computed tomography (CT) images and a radiomics signature was constructed based on a machine learning algorithm. A combined model integrated clinicoradiological predictor and radiomics signature was developed. The predictive performance of the two models was evaluated and compared based on its discrimination, calibration, and clinical usefulness. Results In the training set, 34 (25.0%) patients were confirmed to have EVIT, whereas 26 (21.7%) patients in the testing set had EVIT. When the radiomics signature was added, the combined model showed improved discrimination performance compared to the clinicoradiological model (area under the curves [AUCs] 0.911 vs. 0.772 in the training set; AUCs 0.847 vs. 0.746 in the testing set) and could divide HCC patients into three strata of low, intermediate, or high risk in the two sets. Decision curve analysis demonstrated that the two models were clinically useful, and the combined model provided greater benefits for discriminating patients than the clinicoradiological model. Conclusions This study presents a model that integrates clinicoradiological predictors and CT-based radiomics signature that could provide a preoperative individualized prediction of EVIT in patients with HCC.

Abstract
Pancreatic cancer (PC) is a lethal disease with extremely high mortality. Although surgical resection is the optimal therapeutic approach for PC, about 30%-40% of those patients are not candidates for surgical resection when diagnosed. Chemotherapy and radiotherapy also could not claim a desirable effect on PC. The application of interventional radiology approaches is limited by unavoidable damage to the surrounding vessels or organs. By the superiority of mechanism and technology, IRE could ablate the tumor by creating irreversible pores on the membrane of PC cells with other tissues like vessels and pancreatic ducts untouched. This consensus gathers the theoretical basis and clinical experience from multiple Chinese medical centers, to provide the application principles and experience from Chinese experts in the IRE field.

Abstract
Background It is known that Lnc712 plays an important role in the pathogenesis of breast cancer. However, whether it is involved in hepatocellular carcinoma (HCC) remains unknown. In this study, we aimed to investigate the role and underlying mechanism of Lnc712 in HCC. Methods Sixty-four HCC patients were enrolled and followed up for 5 years to analyze the prognostic value of Lnc712 for HCC. HCC cells were transfected with Lnc712 expression vector, Bach-1 expression vector (or siRNA) and miR-142-3p mimic (or inhibitor) to explore the interactions among Lnc712, miR-142-3p and Bach-1. Cell proliferation, migration, invasion and cell cycle were analyzed by CCK-8 assay, transwell assay, wound healing assay and flow cytometry assay, respectively. Results The expression of Lnc712 was upregulated in HCC, and the upregulated Lnc712 expression was significantly related to poor overall survival in HCC patients. In HCC cells, Lnc712 interacted with miR-142-3p and upregulated Bach-1, a target of miR-142-3p. In addition, Lnc712 promoted HCC cell proliferation, migration, invasion and cell cycle, while its effects were abolished by miR-142-3p mimic. Moreover, miR-142-3p mimic enhanced HCC cell proliferation, migration, invasion and cell cycle, while its effects were abolished by Bach-1 overexpression. miR-142-3p inhibitor repressed cell proliferation, migration, invasion and cell cycle in HCC cells, while its effects were abolished by Bach-1 knockdown. Furthermore, Lnc712 knockdown remarkably inhibited HCC tumor growth in nude mice. Conclusion Lnc712 may promote the development of HCC by targeting the miR-142-3p/Bach-1 axis.

Abstract
Background Bioinformatics provides a valuable tool to explore the molecular mechanisms underlying pathogenesis of hepatocellular carcinoma (HCC). To improve prognosis of patients, identification of robust biomarkers associated with the pathogenic pathways of HCC remains an urgent research priority. Methods We employed the Robust Rank Aggregation method to integrate nine qualified HCC datasets from the Gene Expression Omnibus. A robust set of differentially expressed genes (DEGs) between tumor and normal tissue samples were screened. Weighted gene co-expression network analysis was applied to cluster DEGs and the key modules related to clinical traits identified. Based on network topology analysis, novel risk genes derived from key modules were mined and biological verification performed. The potential functions of these risk genes were further explored with the aid of miRNA–mRNA regulatory networks. Finally, the prognostic ability of these genes was assessed by constructing a clinical prediction model. Results Two key modules showed significant association with clinical traits. In combination with protein–protein interaction analysis, 29 hub genes were identified. Among these genes, 19 from one module showed a pattern of upregulation in HCC and were associated with the tumor node metastasis stage, and 10 from the other module displayed the opposite trend. Survival analyses indicated that all these genes were significantly related to patient prognosis. Based on the miRNA-mRNA regulatory network, 29 genes strongly linked to tumor activity were identified. Notably, five of the novel risk genes, ABAT, DAO, PCK2, SLC27A2, and HAO1, have rarely been reported in previous studies. Gene set enrichment analysis for each gene revealed regulatory roles in proliferation and prognosis of HCC. Least absolute shrinkage and selection operator regression analysis further validated DAO, PCK2, and HAO1 as prognostic factors in an external HCC dataset. Conclusion Analysis of multiple datasets combined with global network information presents a successful approach to uncover the complex biological mechanisms of HCC. More importantly, this novel integrated strategy facilitates identification of risk hub genes as candidate biomarkers for HCC, which could effectively guide clinical treatments.

Abstract
Magnetic hyperthermia therapy (MHT) is able to ablate tumors using an alternating magnetic field (AMF) to heat up magnetocaloric agents (e.g. magnetic nanoparticles) administered into the tumors. For clinical applications, there is still a demand to find new magnetocaloric agents with strong AMF-induced heating performance and excellent biocompatibility. As a kind of biocompatible and biodegradable material, magnesium (Mg) and its alloys have been extensively used in the clinic as an implant metal. Herein, we discovered that the eddy thermal effect of the magnesium alloy (MgA) could be employed for MHT to effectively ablate tumors. Under low-field-intensity AMFs, MgA rods could be rapidly heated, resulting in a temperature increase in nearby tissues. Such AMF-induced eddy thermal heating of MgA could not only be used to kill tumor cells in vitro, but also be employed for effective and accurate ablation of tumors in vivo. In addition to killing tumors in mice, we further demonstrated that VX2 tumors of much larger sizes growing in rabbits after implantation of MgA rods could also be eliminated after exposure to an AMF, illustrating the ability of MgA-based MHT to kill large-sized tumors. Moreover, the implanted MgA rods showed excellent biocompatibility and ∼20% of their mass was degraded within three months. Our work thus discovered for the first time that non-magnetic biodegradable MgA, an extensively used implant metal in clinic, could be used for effective magnetic thermal ablation of tumors under a low-field-intensity AMF. Such a strategy could be readily translated into clinical use.

Abstract
Background Accurate lymph nodes (LNs) assessment is important for rectal cancer (RC) staging in multiparametric magnetic resonance imaging (mpMRI). However, it is incredibly time-consumming to identify all the LNs in scan region. This study aims to develop and validate a deep-learning-based, fully-automated lymph node detection and segmentation (auto-LNDS) model based on mpMRI. Methods In total, 5789 annotated LNs (diameter ≥ 3 mm) in mpMRI from 293 patients with RC in a single center were enrolled. Fused T2-weighted images (T2WI) and diffusion-weighted images (DWI) provided input for the deep learning framework Mask R-CNN through transfer learning to generate the auto-LNDS model. The model was then validated both on the internal and external datasets consisting of 935 LNs and 1198 LNs, respectively. The performance for LNs detection was evaluated using sensitivity, positive predictive value (PPV), and false positive rate per case (FP/vol), and segmentation performance was evaluated using the Dice similarity coefficient (DSC). Findings For LNs detection, auto-LNDS achieved sensitivity, PPV, and FP/vol of 80.0%, 73.5% and 8.6 in internal testing, and 62.6%, 64.5%, and 8.2 in external testing, respectively, significantly better than the performance of junior radiologists. The time taken for model detection and segmentation was 1.3 s/case, compared with 200 s/case for the radiologists. For LNs segmentation, the DSC of the model was in the range of 0.81–0.82. Interpretation This deep learning–based auto-LNDS model can achieve pelvic LNseffectively based on mpMRI for RC, and holds great potential for facilitating N-staging in clinical practice.

Abstract
Background Irinotecan (IRI) is considered an option for second-line treatment of advanced gastric cancer; however, acquired drug resistance currently limits its clinical application. Recently, many researchers have shown that autophagy plays a crucial role in the resistance of tumor cells to chemotherapy and radiotherapy. In this study, we investigated the relationship between autophagy and antitumor activity of IRI in gastric cancer cells. Methods We used MTT assay, flow cytometry and immunofluorescence staining to detect viability, apoptosis and autophagy in gastric cancer. Western blotting assay was used to determine the expression of LC3, Beclin-1, P62, cleaved PARP and Caspase 3. In vivo animal study was performed finally. Results We found that IRI treatment dose- and time-dependently inhibited growth and induced apoptosis in gastric cancer cells. Moreover, IRI treatment caused autophagy in these cells, whereas autophagy inhibitors—3-methyladenine (3-MA), chloroquine (CQ), and Beclin-1 small interfering RNA (siRNA)—suppressed cytotoxicity of IRI. A mechanistic analysis showed that IRI-induced autophagy and apoptosis were related to increased reactive oxygen species (ROS) accumulation and activation of the JNK- and p38-MAPK pathways. Further in vivo experiments revealed that IRI suppressed tumor growth, induced autophagy, and stimulated the JNK- and p38-MAPK pathways, whereas 3-MA attenuated these effects. Conclusion Taken together, these results indicate that IRI stimulates the ROS-related JNK- and p38-MAPK pathways to promote autophagy-dependent apoptosis. Thus, a combination of IRI with a pharmacological autophagy enhancer may be a promising therapeutic strategy against gastric cancer.

Abstract
Background Long noncoding RNAs (lncRNAs) can promote hepatocellular carcinoma (HCC) initiation and progression. In this report, we examined the role of lncRNA LINC02476 in HCC. Methods The expression levels of different lncRNAs in HCC were explored using the TCGA database and lncRNA LINC02476 was selected for further study. The expression of LINC02476 in HCC tissues was determined by real-time PCR. The clinicopathological characteristics of HCC patients were analyzed relative to the expression of LINC02476. The expression of LINC02476 was downregulated in HCC cells using a lentiviral vector and different assays were performed to study cell growth, proliferation, invasion, apoptosis and the cell cycle. MiR-497 was selected as a miRNA that could interact with LINC02476 which was further tested by RNA immunoprecipitation. HMGA2 was selected as a possible target of miR-497, and their interaction was examined by a luciferase reporter assay. Results LINC02476 expression was elevated in HCC cell lines and HCC tissues. When LINC02476 was downregulated, the growth and the invasion of HCC cells decreased in vitro and in vivo. LINC02476 negatively regulated the expression of miR-497 by acting as a ceRNA. HMGA2 was directly targeted and inhibited by miR-497. Conclusion The results indicate that LINC02476 functions through the miR-497/HMGA2 axis and that it has a role in the growth and metastasis of HCC cells. Therefore, LINC02476 could be an interesting new molecular target in HCC therapies.

Abstract
OBJECTIVES To evaluate the safety and short-term outcomes of the modified one-session endovascular treatment with inferior vena cava filter placement and retrieval in one stage for the treatment of acute lower extremity deep vein thrombosis. METHOD Twenty-three patients with unilateral acute lower extremity deep vein thrombosis underwent modified one-session endovascular treatments, which were performed in one stage. Inferior vena cava filter placement without detachment, thrombectomy, and inferior vena cava filter retrieval were performed in one stage. Angioplasty and stent implantation were performed for patients with iliac vein stenosis. Venography was performed to identify the clearance of the thrombus. Color Doppler ultrasound and/or venography were conducted during the follow-up. RESULTS A total of 20/23 (87%) patients with thrombus removal rate >90% successfully underwent modified one-session endovascular treatment. inferior vena cava filters were detached in 3/23 (13%) patients achieving 50%-90% thrombus removal rate. Twenty-one iliac vein stents were implanted in 21/23 (91%) patients with iliac vein stenosis. After treatment, the differences in the circumferences of the affected limb and the healthy limb both significantly decreased. No procedure-related death, symptomatic pulmonary embolism, or major bleeding occurred. During the 12-25 months of follow-up, iliac vein stents and lower extremity veins maintained patent. CONCLUSIONS The modified one-session endovascular treatment with one-stage inferior vena cava filter placement and retrieval might be safe for the treatment of acute lower extremity deep vein thrombosis, and the early clinical outcomes are satisfactory. Placing and retrieving an inferior vena cava filter in one session could safeguard the endovascular interventions as well as reduce the filter-related complications associated with long dwelling times.

Abstract
Interferon-stimulated gene 15 (ISG15) serves a crucial role in hepatocellular carcinoma (HCC) progression. The present study explored the effect of ISG15 knockdown on the sensitivity of HCC cells to norcantharidin. The expression of ISG15 in HCC tissues and cell lines was assessed by reverse transcription-quantitative polymerase chain reaction and immunohistochemistry. Pearson's χ2 test was conducted to analyze the correlation between the clinicopathological features and ISG15 expression of patients with HCC. In addition, HCC cells were transfected with small interfering RNA against ISG15, ISG15 overexpression plasmid or respective negative controls. Cell proliferation, clonogenic ability and apoptosis were examined by Cell Counting Kit-8, colony formation and Annexin V/propidium iodide staining assays, respectively. Protein expression was assessed by western blot analysis. The results revealed that ISG15 was overexpressed in HCC tissues, and that ISG15 expression was positively correlated with HCC differentiation and metastasis. Downregulation of ISG15 increased the sensitivity of HCC cells to norcantharidin, and norcantharidin treatment reversed the tumor-promoting effects of ISG15 overexpression exerted in HCC cells. Furthermore, the expression levels of apoptosis-associated proteins were regulated by ISG15 and norcantharidin. Taken together, the observed increase in the sensitivity of HCC cells to norcantharidin was facilitated by ISG15 knockdown and may provide novel insights for HCC therapy.

Abstract
Intracarotid cold saline infusion (ICSI) brings about neuroprotective effects in ischemic stroke. However, the involvement of serum and glucocorticoid‑regulated kinase 1 (SGK1) in the underlying mechanism of ICSI is not fully understood; therefore, we used the rat middle cerebral artery occlusion (MCAO) model to investigate the neuroprotective effects of ICSI on ischemic stroke in rats, as well as the involvement of SGK1 in these effects. ICSI decreased infarct size and brain swelling, as determined by 2,3,5‑triphenyltetrazolium chloride staining and the dry‑wet weight method, respectively. The results of terminal deoxynucleotidyl transferase mediated nick end labeling (TUNEL) and Nissl staining showed that ICSI also suppressed apoptosis and increased the relative integral optical density (IOD) values of Nissl bodies in the rat MCAO model. Regarding the mechanism, the results of immunohistochemistry and western blotting revealed that ICSI upregulated SGK1 expression and downregulated beclin‑1 and LC‑3 expression in the rat MCAO model. In addition, SGK1 knockdown increased ICSI‑mediated infarct size and brain swelling, promoted apoptosis, and reduced the IOD values of Nissl bodies in the rat MCAO model. In addition, we found that SGK1 knockdown upregulated beclin‑1 and LC‑3 expression mediated by ICSI. Overall, ICSI had a neuroprotective effect on ischemic stroke after reperfusion by upregulating SGK1 and inhibiting autophagy.

Abstract
This study aimed to evaluate the operational performance, embolization effect and safety of CalliSpheres microspheres (CSM) in a porcine renal model. 24 healthy normal pigs were randomized into CSM group and Embosphere microspheres (ESM) group equally, and embolized with CSM or ESM in the lower pole of right kidneys, respectively. On D2, D7 and D28 after the operation, angiography and biochemistry examination were performed, and then the pigs were subjected to renal macroscopic and histopathological examination after euthanasia (4 pigs/group per each time point). The embolization was performed successfully in all pigs without obvious adverse events or deaths, and there was no difference in operation assessments (including number of embolized arteries, volume of injected microspheres and vessel recanalization rate) between CSM group and ESM group. After the operation, all pigs in CSM group and ESM group presented with renal necrosis, stasis and capsule exudation on D2 and D7, and capsule thickening, fibrosis and renal atrophy on D28, and there was no difference in these macroscopic or microscopic manifestations between two groups. For biochemistry indexes (including blood routine, coagulation function, liver function and renal function), most of them were similar between two groups at each time point. CSM embolizes porcine renal artery effectively and safely without obvious adverse events or deaths, which might be a good option for embolization therapy in clinical practices.

Abstract
BACKGROUND Atopic dermatitis (AD) is the most common skin disorder in infancy. However, the diagnosis and definite significance of infantile AD remains a debated issue. OBJECTIVE To analyse the phenotypes of AD in infancy, to establish diagnostic criteria and to estimate the prevalence of this condition in China. METHODS This is a multicentric study, in which 12 locations were chosen from different metropolitan areas of China. Following careful and complete history-taking and skin examination, the definite diagnosis of AD was made and the severity based on the SCORAD index was determined by local experienced dermatologists. Based on the detailed phenotyping, the major and representative clinical features of infantile AD were selected to establish the diagnostic criteria and evaluate their diagnostic efficacy. RESULTS A total of 5967 infants were included in this study. The overall point prevalence of AD was 30.48%. The infantile AD developed as early as at the second month of life, and its incidence peaked in the third month of life at 40.81%. The proportion of mild, moderate and severe AD was 67.40%, 30.57% and 2.03%, respectively. The most commonly seen manifestations in the infantile AD were facial dermatitis (72.07%), xerosis (42.72%) and scalp dermatitis (27.93%). We established the novel diagnostic criteria of infants, which included: (i) onset after 2 weeks of birth; (ii) pruritus and/or irritability and sleeplessness comparable with lesions; and (iii) all two items above with one of the following items can reach a diagnosis of AD: (i) eczematous lesions distributed on cheeks and/or scalp and/or extensor limbs, and (ii) eczematous lesions on any other parts of body accompanied by xerosis. CONCLUSIONS In China, the prevalence of AD in infancy is 30.48% according to clinical diagnosis of dermatologists. The novel Chinese diagnostic criteria for AD in infants show a higher sensitivity and comparable specificity.

Abstract
Objective To investigate the safety, feasibility, and effectiveness of uterine artery embolization in association with methotrexate (MTX) infusion for the treatment of tubal ectopic pregnancy. Methods Fifty-one patients with tubal ectopic pregnancy were referred for interventional management. All patients received super-selective arteriography of the uterine artery, were infused with 50-100 mg methotrexate (MTX) through a catheter, and underwent embolization of the uterine artery with a gel-foam pledge. Clinical presentation, findings of physical examination, β-HCG values, and the size of the ectopic mass were documented for comparison. The concentration of MTX in blood was evaluated at 0.5, 6, 12, 24, 36, and 48 hours after the procedure. Results Forty-seven out of the 51 patients had clinical resolution of their tubal pregnancy (92.2%). The average time for the β-HCG value to decrease and come back to normal was 9.16 ± 2.54 days (mean +/- SD). MTX levels in peripheral blood could not be detected for patients who received 50 or 75 mg MTX at 36 hours after the procedure, while the MTX level was 0.01 μmol/L at 48 hours after the procedure for patients who received 100 mg. Out of the 4 cases whose ectopic mass size was ≥5 cm, 3 failed to respond to the treatment; however, those whose ectopic mass size was ≤5 cm responded positively to the treatment, regardless of the β-HCG concentration and abdominal bleeding, except for 1 patient who had to undergo laparoscopy for severe abdominal pain and who showed a reduction in her β-HCG level. Conclusion Uterine artery embolization in association with methotrexate infusion is safe and effective in the treatment of tubal ectopic pregnancy, especially for those women with mild to moderate bleeding, or for those at risk of a major hemorrhage. The selection criterion of mass size >5 cm should, therefore, be carefully considered.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND The aim of this study was to investigate the reactivation of the hepatitis B virus (HBV) following transarterial chemoembolization (TACE) in primary hepatocellular carcinoma (HCC) patients with HBV-DNA negative and to evaluate the effects of TACE combined with antiviral therapy. METHODS This prospective study involved 98 patients with HBV-related and HBV-DNA negative HCC (HBV DNA < 10 copies/mL) underwent TACE procedures with serial HBV DNA tests. Patients were divided into the antiviral treatment group and the no-antiviral group. The antiviral group received entecavir antiviral therapy, and the other group received no antiviral therapy. Two groups of patients were compared in rate of HBV reactivation and liver function before and after only 1 session of TACE in average 1-month follow-up after operation. P < .05 indicated differences with a statistical significance. RESULTS HBV reactivation occurred in 11 patients in the nonantiviral group (11/47, 23.4%) but only 3 patients in the antiviral group (3/51, 5.9%, P < .05). On multivariate analysis, HBeAg-positive status, number of tumors more than 3, and absence of antiviral therapy were the independent risk predictor of HBV reactivation. Liver function indicators did not differ significantly between the antiviral group and the nonantiviral group in 5 days after TACE. However, the level of alanine aminotransferase and bilirubin were raised and albumin was reduced at the HBV reactivation group compared with no HBV reactivation group (P < .05). At 1 month after TACE, liver function indicators did not differ significantly between the HBV reactivation group and without HBV reactivation group. CONCLUSION HCC patients with HBV DNA negative still remain associated with risk of HBV reactivation after TACE. HBeAg-positive, number of tumors more than 3, and absence of antiviral therapy in HCC patients after TACE have a higher risk of HBV reactivation. Antiviral therapy can reduce the risk of reactivation, helping improve liver function after TACE.

Abstract
PURPOSE Pulmonary benign metastasizing leiomyoma (PBML), a rare condition of smooth muscle tumor, originates from women with a history of uterine leiomyoma (LM). Numerous genetic studies of uterine LM have been reported; however, there are few cytogenetic and molecular descriptions of PBML. Therefore, molecular subtyping is necessary to understand the pathogenesis of metastasizing sites. METHODS Driver gene exon-capture sequencing was performed on one patient's peripheral blood, paraffin samples from primary uterine LM, and lung metastasizing leiomyoma 8 years later. RESULTS The results showed that the same missense mutations of BLMH, LRP2, MED12, SMAD2, and UGT1A8 were concurrently mutated in the primary uterine LM and the PBML. Moreover, a splice mutation of PTEN (c.492+1G>A) was uniquely identified in the lung metastasis of the patient. CONCLUSION This study indicates that the metastatic lung lesions were derived from the same malignant cell clone of uterine LMs and later acquired the novel driver mutations in the evolution of the tumor. In addition, driver gene sequencing can discriminate somatic driver mutations as biological indicators of potential malignant leiomyoma and can identify pathogenic variation driver mutations, which could be used for individualized therapy.

Abstract
Keratosis follicularis spinulosa decalvans (KFSD) is an X-linked condition characterized by keratotic follicular papules and progressive alopecia, which is caused by mutations in the MBTPS2 gene. We carried out a genetic study on a child who was suspected clinically to have KFSD. Sanger sequencing was performed to detect mutations in the entire coding region of MBTPS2. A novel missense mutation (c.599C>T) was identified in the patient, confirming a diagnosis of KFSD. We reviewed related cases with MBTPS2 mutations for evidence of genotype-phenotype correlations.

Abstract
PURPOSE Aspirin could reduce the risk of cancer metastasis. Circulating tumor cells (CTCs) are a key factor of cancer metastasis, but no evidence has revealed how aspirin affects CTCs and its epithelial-mesenchymal transition (EMT). Here, we conducted a clinical trial to investigate how aspirin affects CTCs in metastatic colorectal cancer (MCC) and breast cancer patients (MBC). METHODS The trial is retrospective registered at clinicaltrials.gov (NCT02602938). The eligible patients are given 100 mg aspirin q.d. for 8 weeks, and CTCs are evaluated at baseline, 4 and 8 weeks for absolute number, phenotype (epithelial type, E+, mesenchymal type, M+, and biophenotypic type, B+), and vimentin expression. RESULTS Data on 21 MCC and 19 MBC patients are analyzed, and it revealed that the CTC numbers decreased with aspirin treatment in MCC (p < 0.001) but not MBC (p = 0.0532); besides, ratio of E+ CTCs increased (p = 0.037) and M+ CTCs decreased at 2 months in MCC (p = 0.013), but neither the ratio of E+ or M+ CTCs changes significantly in MBC; vimentin expression of M+ CTCs is higher than E+ and B+ CTCs either in MBC or MCC patients at baseline (p < 0.01); and aspirin suppresses the vimentin expression in M+ (p = 0.002)and B+ (p = 0.006) CTCs of MCC and M+ CTCs of MBC (p = 0.004); besides it find vimentin expression in B+ (p = 0.004) or M+ (p < 0.001), CTCs are markedly decreased in patients with total CTC numbers declined. CONCLUSION Aspirin could decrease CTCs numbers and block EMT transition in MCC patients and part of MBC patients.

Abstract
Osteoid osteoma of the atlas has previously been reported very rarely in the published literature. The traditional standard treatment has been a surgical resection of the nidus. Recently, computed tomography (CT)-guided radiofrequency ablation (RFA) has gained favor as a more precise alternative treatment. Here, we present a case of osteoid osteoma of the C1 lateral mass treated successfully using CT-guided RFA. A 30-year-old woman who presented with a four-month history of occipital and suboccipital pain was treated by CT-guided RFA. The visual analog scale (VAS) assessed the pain before and after RFA. The patient reported significant pain relief and normal activities. The VAS score reduced from 8/7 to 1/0 after the procedure. Therefore CT-guided percutaneous RFA of C1 vertebral osteoid osteoma is a safe and effective method. The technique might be contraindicated when the nidus is less than 2 mm away from the neural structures.

Abstract
BACKGROUND The aims of this paper were to evaluate the biological characteristics of lower extremity deep venous thrombosis (DVT) by applying acoustic radiation force impulse imaging technique (ARFI), explore the correlation between the value of shear wave speed (SWV) and short-term efficacy of thrombolytic therapy as well as analyze the application value of shear wave velocity in predicting the short-term efficacy of thrombolytic therapy. METHODS ARFI for 120 patients with lower extremity DVT was examined and the shear wave velocity values were measured. The thrombus SWV value among the cured group, effective treatment group and ineffective group according to the different effect of thrombolytic therapy and were analyzed and then the cured and effective treatment group were classified into total effective group. The effectiveness and thrombus SWV were compared. The Receiver Operating Characteristic was constructed and the critical effective value of SWV thrombolysis were evaluated. RESULTS The SWV value has a certain correlation with the effect of thrombolysis. The thrombus in cured group and effective treatment group were significantly less than the ineffective group. There was no significant thrombus hardness difference between cured group and effective group. SWV value can predict the effect of thrombolytic therapy. The critical value was 1.925, which was greater than that of the patients with a poor prognosis, with a sensitivity of 65.59% and a specificity of 88.89%. CONCLUSIONS The SWV value has a certain correlation with the thrombolysis effect. The biological characteristics of lower extremity DVT can be evaluated by acoustic pulse radiation force imaging technology, which has high value for the clinical treatment plan and the prediction of thrombolysis effect.

In this study, the diffusional kurtosis imaging method was used to investigate WM microstructural alterations in patients with type 2 diabetes mellitus and to detect associations between diffusional kurtosis imaging metrics and clinical/cognitive measurements. MATERIALS AND METHODS Diffusional kurtosis imaging and cognitive assessments were performed on 58 patients with type 2 diabetes mellitus and 58 controls. Voxel-based intergroup comparisons of diffusional kurtosis imaging metrics were conducted, and ROI-based intergroup comparisons were further performed. Correlations between the diffusional kurtosis imaging metrics and cognitive/clinical measurements were assessed after controlling for age, sex, and education in both patients and controls. RESULTS Altered diffusion metrics were observed in the corpus callosum, the bilateral frontal WM, the right superior temporal WM, the left external capsule, and the pons in patients with type 2 diabetes mellitus compared with controls. The splenium of the corpus callosum and the pons had abnormal kurtosis metrics in patients with type 2 diabetes mellitus. Additionally, altered diffusion metrics in the right prefrontal WM were significantly correlated with disease duration and attention task performance in patients with type 2 diabetes mellitus. CONCLUSIONS With both conventional diffusion and additional kurtosis metrics, diffusional kurtosis imaging can provide additional information on WM microstructural abnormalities in patients with type 2 diabetes mellitus. Our results indicate that WM microstructural abnormalities occur before cognitive decline and may be used as neuroimaging markers for predicting the early cognitive impairment in patients with type 2 diabetes mellitus.

Abstract
OBJECTIVE To evaluate the feasibility and success rate of in-plane ultrasound-guided paravertebral block using laterally intercostal approach. METHODS In the study, 27 patients undergoing elective thoracic surgery were selected to do paravertebral block preoperatively. The fifth intercostal space was scanned by ultrasound probe which was placed along the long axis of the rib and 8 cm lateral to the midline of the spine. The needle was advanced in increments aiming at the space between the internal and innermost intercostal muscles. Once the space between the muscles was achieved, 20 mL of 0.5% (mass fraction) ropivacaine was injected and a catheter was inserted. Whether the tip of catheter was in right place was evaluated by ultrasound image. The block dermatomes of cold sensation were recorded 10, 20 and 30 min after the bolus drug was given. Then 0.2% ropivacaine was infused with 6 mL/h via the catheter by an analgesia pump postoperatively. The block dermatomes of cold sensation and pain score were recorded 1, 6, 24 and 48 h postoperatively. RESULTS The first attempt success rate of catheteration was 81.48% (22/27); the tips of catheter were proved in right places after the second or third attempt in 5 patients. The median numbers of the block dermatomes 10, 20 and 30 min after the bolus drug was given were 2, 3, 4; the median numbers of block dermatomes were 5, 5, 5, 4, and of pain score were 1, 1, 2, 2 at 1, 6, 24, 48 h postoperatively; no case of bilateral block, pneumothorax or vessel puncture occurred. CONCLUSION Thoracic paravertebral block using laterally intercostal approach is feasible, which has high success rate of block and low rate of complications.
