Abstract
Derivative spectroscopy is used to separate the small absorption peaks superimposed on the main absorption band, which is widely adopted in modern spectral analysis to increase both the valid spectral information and the identification accuracy. In this study, a method based on attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) with first-order derivative (FD) processing combined with chemometrics is proposed for rapid qualitative and quantitative analysis of Panax ginseng polysaccharides (PGP), Panax notoginseng polysaccharides (PNP), and Panax quinquefolius polysaccharides (PQP). First, ATR-FTIR with FD processing was used to establish the discriminant model combined with principal component analysis (PCA), partial least squares discriminant analysis (PLS-DA) and linear discriminant analysis (LDA). After that, two-dimensional ATR-FTIR based on single-characteristic temperature as external interference (2D-sATR-FTIR) was established using ATR-FTIR with FD processing. Then, ATR-FTIR with FD processing was combined with PLS to establish and optimize the quantitative regression model. Finally, the established discriminant model and 2D-sATR-FTIR successfully distinguished PGP, PNP and PQP, and the optimal PLS regression model had a good prediction ability for the Panax polysaccharide extracts content. This strategy provides an efficient, economical and nondestructive method for the distinction and quantification of PGP, PNP and PQP in a short detection time.

Abstract
PURPOSE While the role of drug-eluting beads transarterial chemoembolization (DEB-TACE) for hepatocellular carcinoma (HCC) is established, questions regarding appropriate bead size for use in patients remain. This trial evaluated the effectiveness and safety of DEB-TACE using small-size (≤ 100 μm) microspheres loaded with epirubicin. MATERIALS AND METHODS This prospective, single-arm, multicenter study enrolled patients diagnosed with HCC who underwent DEB-TACE using 40 (range, 30-50), 75 (range, 60-90), or 100 (range, 75-125) μm epirubicin-loaded microspheres (TANDEM microspheres, Varian Medical). Bead size was at the discretion of treating physicians and based on tumor size and/or vascular structure. The primary outcome measure was 6-month objective response rate (ORR). Secondary outcome measures were 30-day and 3-month ORR, time to tumor progression and extrahepatic spread, proportion of progression-free survival and overall survival (OS) at one year, and incidence of treatment-associated adverse events. RESULTS Data from 108 patients from ten centers was analyzed. Six-month ORR was 73.3 and 71.3% based on European association for the study of the liver (EASL) and modified response evaluation criteria in solid tumors (mRECIST) criteria, respectively. Thirty-day ORR was 79.6% for both EASL and mRECIST criteria with 3-month ORR being 80.0 and 81.0%, respectively, for each criteria. One-year PPF and OS rate were 60.3 and 94.3%. There was a total of 30 SAEs reported to be likely to definitely associated with microsphere (n = 9), epirubicin (n = 9), or procedure (n = 12) with none resulting in death. CONCLUSION DEB-TACE using epirubicin-loaded small-sized (≤ 100 μm) microspheres demonstrates promising local tumor control and acceptable safety in patients with HCC.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common malignancies and the third leading cause of cancer-related deaths globally. Hepatic arterial infusion chemotherapy (HAIC) treatment is widely accepted as one of the alternative therapeutic modalities for HCC owing to its local control effect and low systemic toxicity. Nevertheless, although accumulating high-quality evidence has displayed the superior survival advantages of HAIC of oxaliplatin, fluorouracil, and leucovorin (HAIC-FOLFOX) compared with standard first-line treatment in different scenarios, the lack of standardization for HAIC procedure and remained controversy limited the proper and safe performance of HAIC treatment in HCC. Therefore, an expert consensus conference was held on March 2023 in Guangzhou, China to review current practices regarding HAIC treatment in patients with HCC and develop widely accepted statements and recommendations. In this article, the latest evidence of HAIC was systematically summarized and the final 22 expert recommendations were proposed, which incorporate the assessment of candidates for HAIC treatment, procedural technique details, therapeutic outcomes, the HAIC-related complications and corresponding treatments, and therapeutic scheme management.

Abstract
PURPOSE To compare the safety and efficacy of intraluminal brachytherapy with iodine-125 (125I) seed strand implantation combined with and without stent placement to treat patients with obstructive jaundice induced by tumor thrombus. METHODS Between January 2018 and June 2022, 42 patients with malignant obstructive jaundice (MOJ) induced by tumor thrombus were included. 20 patients received 125I seed strand implantation and stent placement (group A). The remaining 22 patients, implanted 125I seed strands only, served as control (group B). The two groups' overall survival and jaundice-free survival were compared using the Kaplan-Meier method and log-rank test. RESULTS During the follow-up period, the mean survival time of group A was 38.0 ± 4.1 months (95%CI, 30.0-46.1 months), while that of group B was 25.1 ± 2.8 (95% CI, 19.5-30.6 months) (p = 0.406). The mean survival rates of 12 months for all patients, group A, and group B was 66.7%, 65%, and 68%, respectively. The mean jaundice-free survival of group A and group B were 34.0 ± 3.6 months (95% CI, 27.9-41.2months) and 22.9 ± 2.7 months (95%CI, 17.5-28.2months) (p = 0.254), respectively. Two PTBD drainage tube infection cases occurred in group A and group B separately. CONCLUSIONS 125I intraluminal brachytherapy is an effective and safe therapy for treating patients with obstructive jaundice induced by tumor thrombus.

Abstract
OBJECTIVES To investigate the therapeutic effect of recombinant human growth hormone (rhGH) on children with growth hormone deficiency (GHD) and different pituitary developmental conditions. METHODS A prospective study was performed on 90 children with GHD who were admitted to Xuchang Maternity and Child Health Hospital from June 2020 to December 2021. According to pituitary height on the median sagittal plane, they were divided into three groups: pituitary dysplasia group (n=45), normal pituitary group (n=31), and enlarged pituitary growth group (n=14). The changes in body height, growth velocity, height standard deviation score and serum levels of insulin-like growth factor binding protein-3 (IGFBP-3) and insulin-like growth factor-1 (IGF-1) were examined after treatment in the above three groups, and the differences of the above indices before and after treatment were compared among the three groups. RESULTS After treatment, all three groups had significant increases in body height, growth velocity, height standard deviation score, and the serum levels of IGFBP-3 and IGF-1 (P<0.05). Compared with the normal pituitary group, the pituitary dysplasia group and the enlarged pituitary growth group had significantly higher values in terms of the differences in body height, growth velocity, height standard deviation score, IGF-1, and IGFBP-3 before and after treatment (P<0.05). There was no significant difference in the incidence rate of adverse reactions among the three groups (P>0.05). CONCLUSIONS In GHD children with different pituitary developmental conditions, rhGH can promote bone growth and increase body height, especially in children with pituitary dysplasia and pituitary hyperplasia, with good safety.

Abstract
Normothermic machine perfusion (NMP) could provide a curative treatment to reduce biliary injury in donation after cardiac death (DCD) donor livers; however, the underlying mechanisms remain poorly understood. In a rat model, our study compared air-oxygenated NMP to hyperoxygenated NMP and found that air-oxygenated NMP improved DCD functional recovery. Here, we found that the charged multivesicular body protein 2B (CHMP2B) expression was substantially elevated in the intrahepatic biliary duct endothelium of the cold-preserved rat DCD liver after air-oxygenated NMP or in biliary endothelial cells under hypoxia/physoxia. CHMP2B knockout (CHMP2B-/-) rat livers showed increased biliary injury after air-oxygenated NMP, indicated by decreased bile production and bilirubin level, elevated biliary levels of lactate dehydrogenase and gamma-glutamyl transferase. Mechanically, we demonstrated that CHMP2B was transcriptionally regulated by Kruppel-like transcription factor 6 (KLF6) and alleviated biliary injury through decreasing autophagy. Collectively, our results suggested that air-oxygenated NMP regulates CHMP2B expression through the KLF6, which reduces biliary injury by inhibiting autophagy. Targeting the KLF6-CHMP2B autophagy axis may provide a solution to reducing biliary injury in DCD livers undergoing NMP.

Abstract
Objective To evaluate the safety and efficacy of interventional therapy (iodine-125[125I] seed strand and portal vein stent [PVS] implantation plus transarterial chemoembolization [TACE]) combined with systemic therapy (lenvatinib plus anti-PD-1 antibody) as first-line treatment for hepatocellular carcinoma (HCC) patients with Vp4 portal vein tumor thrombus (PVTT). Patients and methods From December 2018 to October 2021, 87 HCC patients with Vp4 PVTT were included in this single-center retrospective study. Forty-seven patients underwent interventional therapy combined with lenvatinib and anti-PD-1 antibody (group A), while 40 cases underwent interventional therapy combined with lenvatinib only (group B). Overall response rate (ORR), stent occlusion rates (SOR), median overall survival (OS), median progression-free survival (PFS) and median stent patency time (SPT) were compared between the 2 groups. Results The mean intended dose (r = 10 mm; z = 0; 240 days) was 64.9 ± 1.0 Gy and 64.5 ± 1.1 Gy in group A and B, respectively (p = 0.133). ORR and SOR were significantly different between group A and B (ORR, 55.3% vs 17.5%, p < 0.001; SOR, 12.8% vs 35.0%, p = 0.014). In the propensity-score matching (PSM) cohort, the median OS, median PFS and median SPT were significantly longer in group A compared with group B (32 PSM pairs; OS, 17.7 ± 1.7 vs 12.0 ± 0.8 months, p = 0.010; PFS, 17.0 ± 4.3 vs 8.0 ± 0.7 months, p < 0.001; SPT, not-reached vs 12.5 ± 1.1 months, p = 0.028). Conclusion This interventional therapy combined with lenvatinib and anti-PD-1 antibody is safe and effective for HCC patients with Vp4 PVTT.

Abstract
The realization of luminescent materials with narrowband and circularly polarized luminescence (CPL) is of great significance for the development of future optical and photonic devices. Herein, through a steric-hindrance-assisted dual-core strategy, two pairs of chiral dual-core multiple resonance thermally activated delayed fluorescence (MR-TADF) materials (R/S-DOBN and R/S-DOBNT) are directly constructed by the bonding of two organoboron MR-TADF monocores (SOBN and SOBNT) with carbazole/3,6-di-tert-butyl-9H-carbazole and phenol derivative as donors, realizing obvious CPL and narrowband emissions. Furthermore, the dual-core effect in the prepared R/S-DOBN and R/S-DOBNT increases the transition oscillator strength two times more than that of a monocore structure, while maintaining the ultrapure blue emissions peaking at 453 and 459 nm with a narrower full-width at half-maximum of 21 nm through reorganization energy reduction. The circularly polarized organic light-emitting diodes based on the enantiomers exhibit ultrapure blue emission with Commission Internationale de L'Eclairage (CIE) coordinates of (0.14, 0.10) and (0.13, 0.12), high maximum external quantum efficiencies of 23.9% and 25.6%, and obvious circularly polarized electroluminescence with dissymmetry factors (|gEL |) ≈ 10-3 .

Abstract
The risk of chronic hepatitis B (CHB) infection is often affected by polyunsaturated fatty acids (PUFAs) metabolism which is strongly influenced by single nucleotide polymorphisms (SNPs) within the PUFA metabolic pathway. Given this, we designed this study to determine the relationship between specific polymorphisms within fatty acid desaturase 2 (FADS2), a key enzyme in PUFA metabolism, and CHB infection. We completed this evaluation using a case-control study comprising 230 CHB patients and 234 unrelated healthy controls in which the genetic relationships between three previously identified SNPs, isolated via mass spectrometry, and CHB infection. Our data revealed that none of these three SNPs (rs174568, rs174601, and rs2727270) were significantly associated with susceptibility to CHB infection when compared to healthy controls. However, when we stratified our cohort by sex, male subjects with the TC genotype for FADS2 exhibited a decreased risk for CHB infection (OR = 0.62, 95%CI = 0.39-0.96; OR = 0.64, 95%CI = 0.41-1.00; OR = 0.57, 95%CI = 0.36-0.90). Furthermore, age stratification revealed that both the T allele and the TC genotypes for each of the three target SNPs were less common in Chinese CHB cases in people younger than 50 years old. Correlation analysis also revealed that there was no statistically significant relationship between these three SNPs and HBV-DNA replication or hepatitis B surface antigen (HBsAg) levels. Thus, our data suggests that rs174568, rs174601, and rs2727270 may affect the CHB outcomes in various age or sex subgroups, suggesting that they may be useful predictive or diagnostic biomarkers of CHB infection in some populations.

Abstract
BACKGROUND AND AIMS Hepatic ischemia-reperfusion injury (IRI) is a common complication of hepatectomy and liver transplantation. However, the mechanisms underlying hepatic IRI have not been fully elucidated. Regulator of G-protein signaling 14 (RGS14) is a multifunctional scaffolding protein that integrates the G-protein and mitogen-activated protein kinase (MAPK) signaling pathways. However, the role of RGS14 in hepatic IRI remains unclear. APPROACH AND RESULTS We found that RGS14 expression increased in mice subjected to hepatic ischemia-reperfusion (IR) surgery and during hypoxia reoxygenation in hepatocytes. We constructed global RGS14 knockout (RGS14-KO) and hepatocyte-specific RGS14 transgenic (RGS14-TG) mice to establish 70% hepatic IRI models. Histological hematoxylin and eosin staining, levels of alanine aminotransferase and aspartate aminotransferase, expression of inflammatory factors, and apoptosis were used to assess liver damage and function in these models. We found that RGS14 deficiency significantly aggravated IR-induced liver injury and activated hepatic inflammatory responses and apoptosis in vivo and in vitro. Conversely, RGS14 overexpression exerted the opposite effect of the RGS14-deficient models. Phosphorylation of TGF-β-activated kinase 1 (TAK1) and its downstream effectors c-Jun N-terminal kinase (JNK) and p38 increased in the liver tissues of RGS14-KO mice but was repressed in those of RGS14-TG mice. Furthermore, inhibition of TAK1 phosphorylation rescued the effect of RGS14 deficiency on JNK and p38 activation, thus blocking the inflammatory responses and apoptosis. CONCLUSIONS RGS14 plays a protective role in hepatic IR by inhibiting activation of the TAK1-JNK/p38 signaling pathway. This may be a potential therapeutic strategy for reducing incidences of hepatic IRI in the future.

Abstract
Direct emission of circularly polarized light from organic light-emitting diodes (OLEDs) is a research hotspot as it could increase the efficiency and significantly simplify device architecture of OLED-based 3D displays. In this study, R/S-OBS-Cz and R/S-OBS-TCz with axial chirality were efficiently prepared by using a stable chiral octahydro-binaphthol unit, carbazole/3,6-ditert-butylcarbazole donors, and a 5,5,10,10-tetraoxide acceptor. The chiral unit-acceptor-donor structure provides them not only thermally activated delayed fluorescence (TADF) characteristics with minor singlet-triplet energy gaps of 0.04 and 0.05 eV but also obvious circularly polarized photoluminescence (CPPL) phenomenon with dissymmetry factors of 8.7 × 10-4 and 6.4 × 10-4 in codoped films. Meanwhile, the CP-OLEDs prepared by enantiomers exhibit good device performances with the maximum external quantum efficiency reaching 20.3% and ideal efficiency roll-off as well as obvious CPEL properties with a |gEL| factor up to 1.0 × 10-3.

Abstract
Recent development of most organic long persistent luminescence (OLPL) systems employed binary or tertiary doping. However, the design strategies towards OLPL materials with hour-long afterglow duration are still quite limited. Here, we propose a novel OLPL system through melt-casting method with 0.1 mol % of CuI complexes: 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl BINAP-CuX (X=Cl, Br and I) doped into the triphenylphosphine (TPP) host. The charge separation was initiated prior to excitation through host coordination with CuI complexes, resulting in semi-free halogen ions and in situ generated CuI cations, which forms TPP + BINAP-CuX ionic pairs and subsequently ionic solids. The OLPL lifetime can be readily modulated by different halogen atoms and the afterglow can last up to more than 3 hours perceivable to human eyes. This is a rare example of OLPL initiated through host-guest coordination that could potentially expand the definition of OLPL systems and design strategies.

METHODS Single-center retrospective study from 2017-2019 in 190 patients who underwent percutaneous transhepatic portal vein interventions. The transhepatic puncture tracts were embolized with n-BCA in 88 patients (Group A) and with coils in 102 patients (Group B). Procedure-related complications and image noise around coils and n-BCA were compared between the groups. No significant differences were noted at baseline between both groups (platelets, coagulation, liver disease, types of procedures, liver function, liver tumors). RESULTS All patients underwent transhepatic puncture tract embolization. Procedure-related complications were only observed in patients from Group B: subcapsular hemorrhage (n = 2; 1.96%), hepatic artery hemorrhage (n = 1; 0.98%), and pseudoaneurysms combined with hemobilia occurred (n = 1; 0.98%). In Group A, the distal part of the punctured portal vein branch was embolized with n-BCA in 1 patient (1.14%). Four major complications in Group B Vs 0 in Group A were observed, respectively (p < 0.0001). The image noise around n-BCA was significantly lower than that around coils (10.7 ± 1.7 HU vs. 54.3 ± 15.0 HU, p < .001). CONCLUSIONS n-BCA tract embolization is more effective than using coils, with fewer bleeding events, at the cost of a higher potential for unintended embolization of portal vein branches.

Abstract
Objectives: To investigate the predictive value of inflammatory biomarkers in patients with unresectable hepatocellular carcinoma (HCC) for outcomes following the combination treatment of transarterial chemoembolization (TACE) plus sorafenib. Materials and Methods: A total of 314 (270 male and 44 female) treatment-naïve patients with unresectable HCC treated by TACE plus sorafenib between January 2011 and December 2018 were enrolled in the retrospective study. The primary outcome was overall survival (OS). The secondary outcome was progression-free survival (PFS). Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were obtained within 3–7 days before the initial TACE and the median value of the NLR and PLR was considered as the cut-off value. Results: The median value of NLR and PLR was 2.42 and 100, respectively. The median OS and PFS of the entire cohort were 18.7 months (95% CI: 16.8–20.6) and 9.1 months (95% CI: 8.5–9.8), respectively. The low NLR and PLR group showed improved OS and PFS compared with the high NLR and PLR group [21.8 months (95% CI: 15.2–28.5) vs. 15.4 months (95% CI: 12.4–18.3), p < 0.0001; 21.6 months (95% CI: 15.8–27.5) vs. 14.9 months (95% CI: 11.9–17.8), p = 0.00027, respectively]. In addition, the low NLR and PLR group also provided a longer PFS than the high NLR and PLR group [10.4 months (95% CI: 8.9–12.0) vs. 8.1 months (95% CI: 7.1–9.2), p = 0.00022; 10.3 months (95% CI: 8.6–11.9) vs. 8.2 months (95% CI: 7.2–9.2), p < 0.0001, respectively]. High NLR and PLR at baseline were predictive factors of poor OS (p = 0.02 and p = 0.004) and PFS (p = 0.045 and p = 0.005). Conclusion: This study showed the prognostic value of quantitative inflammatory biomarkers in correlation with OS and PFS in unresectable HCC patients undergoing TACE plus sorafenib treatment.

Abstract
e16152 Background: We reviewed real-world outcomes for patients with uHCC and PVTT receiving TACE with 125I seed and stent implantation combined with lenvatinib plus anti-PD-1 antibodies. Methods: We retrospectively reviewed medical records from 62 consecutive adult (≥18 to ≤75 years) patients with HBV-related HCC and type III and IV PVTT with Child-Pugh class A or B liver function and ECOG performance status of 0-2 who received 125I seed strand and stent implantation combined with TACE at our center between November 2018 and May 2020. Patients were divided into two groups; those who had received adjuvant lenvatinib plus anti-PD-1 inhibitors, initiated 3 days after the first interventional procedure (Group A; n=18), and those who only received locoregional therapy (Group B; n=44). Propensity score matching (PSM) with a 1:1 ratio was used to reduce selection bias. Tumor response, progression-free survival (PFS, time from the first interventional procedure to progression or death for both Group A and Group B) and time-to-progression (TTP) were assessed using the modified Response Evaluation Criteria in Solid Tumors (mRECIST). Time to untreatable progression (TTUP) and overall survival (OS) were also assessed. Adverse events (AEs) were graded according to the Common Toxicity Criteria for Adverse Events (CTCAE) v4.0. Results: PSM resulted in 15 matched pairs of patients, and baseline demographic parameters were comparable between the two groups. The median follow-up time was 12.4 ± 4.6 and 9.4 ± 4.8 months for patients in Groups A (n=15) and B (n=15) after PSM, respectively. Compared with patients in Group B, those in Group A had a higher overall response rate (66.7 vs. 18.2%; p=0.001) and disease control rate (72.2 vs. 43.2%; p=.038) and a longer median PFS, TTP, TTUP and OS (Table). No serious complications related to locoregional procedures were reported in either group. In Group A, 13% (n=2) of patients experienced ≥1 AE but the majority were Grade <3; one patient had Grade 2 hyperthyroidism and one had Grade 2 enteritis, which were both considered related to immunotherapy. Conclusions: These real-world data show that 125I seed strand and stent implantation combined with TACE plus adjuvant lenvatinib and anti-PD-1 antibodies led to better treatment responses and survival outcomes compared with locoregional treatment alone in patients with uHCC and PVTT, with an acceptable safety profile. Summary of survival outcomes in propensity score matched groups.[Table: see text]

Abstract
Objectives: To use baseline variables to predict one-year disease control for patients with hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE) combined with sorafenib as initial treatment by applying a machine learning approach based on the random survival forest (RF) model. Materials and Methods: The multicenter retrospective study included 496 patients with HCC treated with TACE combined with sorafenib between January 2014 and December 2018. The independent risk factors associated with one-year disease control (complete response, partial response, stable disease) were identified using the RF model, and their predictive importance was determined using the Gini index. Tumor response was assessed according to modified Response Evaluation Criteria in Solid Tumors. Results: The median overall survival was 15.5 months. A total of 186 (37.5%) patients achieved positive one-year disease control. The Barcelona Clinic Liver Cancer (BCLC) stage (Gini index: 20.0), tumor size (≤7 cm, >7 cm; Gini index: 9.0), number of lobes involved (unilobar, bilobar; Gini index: 6.4), alpha-fetoprotein level (≤200 ng/dl, >200 ng/dl; Gini index: 6.1), albumin-bilirubin grade (Gini index: 5.7), and number of lesions (1, >1; Gini index: 5.3) were identified as independent risk factors, with the BCLC stage as the most important variable. The RF model achieved a higher concordance index of 0.724 compared to that for the logistic regression model (0.709). Conclusions: The RF model is a simple and accurate approach for prediction of one-year disease control for patients with HCC treated with TACE combined with sorafenib.

Abstract
Purpose To establish albumin-bilirubin (ALBI) grade-based and Child-Turcotte-Pugh (CTP) grade-based nomograms, as well as to develop an artificial neural network (ANN) model to compare the prognostic performance and discrimination of these two grades for hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE) combined with sorafenib as an initial treatment. Methods This multicenter retrospective study included patients from three hospitals between January 2013 and August 2018. In the training cohort, independent risk factors associated with overall survival (OS) were identified by univariate and multivariate analyses. The nomograms and ANN were established and then validated in two validation cohorts. Results A total of 504 patients (319, 61, and 124 patients from hospitals A, B, and C, respectively) were included. The median OS was 15.2, 26.9, and 14.8 months in the training cohort and validation cohorts 1 and 2, respectively (P = 0.218). In the training cohort, both ALBI grade and CTP grade were identified as independent risk factors. The ALBI grade-based and CTP grade-based nomograms were established separately and showed similar prognostic performance and discrimination when validated in the validation cohorts (C-index in validation cohort 1: 0.799 vs. 0.779, P = 0.762; in validation cohort 2: 0.700 vs. 0.693, P = 0.803). The ANN model showed that the ALBI grade had higher importance in survival prediction than the CTP grade. Conclusions The ALBI grade and CTP grade have comparable prognostic performance for HCC patients treated with TACE combined with sorafenib. ALBI grades 1 and 2 have the potential to act as a stratification factor for clinical trials on the combination therapy of TACE and systemic therapy.

Abstract
Objectives To develop and validate a deep learning-based overall survival (OS) prediction model in patients with hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE) plus sorafenib. Methods This retrospective multicenter study consisted of 201 patients with treatment-naïve, unresectable HCC who were treated with TACE plus sorafenib. Data from 120 patients were used as the training set for model development. A deep learning signature was constructed using the deep image features from preoperative contrast-enhanced computed tomography images. An integrated nomogram was built using Cox regression by combining the deep learning signature and clinical features. The deep learning signature and nomograms were also externally validated in an independent validation set of 81 patients. C-index was used to evaluate the performance of OS prediction. Results The median OS of the entire set was 19.2 months and no significant difference was found between the training and validation cohort (18.6 months vs. 19.5 months, P = 0.45). The deep learning signature achieved good prediction performance with a C-index of 0.717 in the training set and 0.714 in the validation set. The integrated nomogram showed significantly better prediction performance than the clinical nomogram in the training set (0.739 vs. 0.664, P = 0.002) and validation set (0.730 vs. 0.679, P = 0.023). Conclusion The deep learning signature provided significant added value to clinical features in the development of an integrated nomogram which may act as a potential tool for individual prognosis prediction and identifying HCC patients who may benefit from the combination therapy of TACE plus sorafenib.

Abstract
OBJECTIVES 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. MATERIALS AND METHODS This multicentre, retrospective study consisted of 185 consecutive treatment-naïve 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. RESULTS 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). CONCLUSIONS 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.

Abstract
The host-guest chemistry of metal-organic frameworks (MOFs) has enabled the derivation of numerous new functionalities. However, intrinsically chiral MOFs (CMOFs) with helical channels have not been used to realize crystalline circularly polarized luminescence (CPL) materials. Herein, enantiomeric pairs of MOF crystals are reported, where achiral fluorophores adhere to the inner surface of helical channels via biology-like H-bonds and hence inherit the helicity of the host MOFs, eventually amplifying the luminescence dissymmetry factor (glum ) of the host l/d-CMOF (±1.50 × 10-3 ) to a maximum of ±0.0115 for the composite l/d-CMOF⊃fluorophores. l/d-CMOF⊃fluorophores in pairs generate bright color-tunable CPL and almost ideal white CPL (0.33, 0.32) with a record-high photoluminescence quantum yield of ≈30%, which are further assembled into a white circularly polarized light-emitting diode. The present strategy opens a new avenue for propagating the chirality of MOFs to realize universal chiroptical materials.

Abstract
[n]Helicene derivatives are most popular chiral structures to construct luminescent materials with circularly polarized (CP) light, which have revealed appealing application in chiral optoelectronics. Particularly, because of the unique phosphorescent emission, platinahelicene has great application prospects in CP organic light-emitting diode (CP-OLED). Herein, by decorating the pyridinyl-helicene ligand with trifluoromethyl (-CF3) unit in a specific position, a pair of platinahelicene enantiomers was prepared and separated with extremely twisted structure showing not only superior thermal and configurational stability but also good CP luminescence (CPL) property with dissymmetry factors (|gPL|) of 6 × 10−3. Moreover, the evaporated CP-OLEDs based on platinahelicene enantiomers exhibited the deep-red emission with the peak at 653 nm as well as obvious CP electroluminescence (CPEL) signals with the |gEL| in 10−3 order. Therefore, the design strategy provides an efficient way to improve the CPL properties of platinahelicene to cope with the future application in CP-OLEDs.

Abstract
Development of simple chiral materials with tunable circularly polarized photoluminescence (CPPL) and circularly polarized electroluminescence (CPEL) for efficient circularly polarized organic light-emitting diodes (CP-OLEDs) is the key toward future 3D displays. In this study, four pairs of chiral 1,2-diaminocyclohexane-based fluorescence enantiomers were efficiently prepared with high yields (up to 92%) and enantiomeric excesses (ee >99%). By the introduction of N-methyl, carbazole, and diphenylamine-donating groups, these materials showed multicolor CPPL and CPEL from blue (420 nm) to red (610 nm) with good thermal and conformational stability. The multilayer CP-OLEDs based on these enantiomers show high external quantum efficiency of up to 5.5% with low-efficiency roll-off and microimage circularly polarized electroluminescence with a dissymmetry factor (gEL) of up to -1.4 × 10-3/+1.3 × 10-3. These results push forward the development of future multicolor circularly polarized electroluminescent materials.

Abstract
BACKGROUND This study aims to investigate symptoms of dry eye and signs of ocular surface disease in children with myopia during OK lens wear. METHODS A total of 68 subjects were prospectively managed with OK lens correction. These subjects were 8-14 years of age with myopia -0.50 to -5.00 dioptres of sphere and astigmatism of≤1.00 dioptres of cylinder. Patients with any ocular disease were ruled out from this study. All subjects completed a dry eye symptom questionnaire for OSDI scoring, corneal fluorescein staining, tear film break up time (TBUT) test and Schirmer's test I during the follow-up period. The follow-up period includes the primary visit (baseline), and at one day, one week, one month and six months after wearing the lens. RESULTS In terms of dry eye symptoms, we found that OSDI scores were significantly high after one day of wearing the lens (P<0.05). Additionally, TBUT values significantly decreased after one day (P<0.01) and one week (P<0.05) of wearing the OK lens. Corneal staining grade also significantly increased after one day and one week of wearing the OK lens. Furthermore, Schirmer's Test I values slightly, but not significantly, increased after one day and one week of wearing the lens. All variables returned to pre-wear levels at one month after wearing the lens, which remained stable up to six months of wearing the OK lens. CONCLUSION Our study is the first reveal that OK lens wear in children leads to dry eye symptoms and disturbs the tear film during the initial period of OK lens wear. However, this did not significantly interfere with tear secretion during the follow-up period.

Abstract
Pure organic materials with intrinsic room-temperature phosphorescence typically rely on heavy atoms or heteroatoms. Two different strategies towards constructing organic room-temperature phosphorescence (RTP) species based upon the through-space charge transfer (TSCT) unit of [2.2]paracyclophane (PCP) were demonstrated. Materials with bromine atoms, PCP-BrCz and PPCP-BrCz, exhibit RTP lifetime of around 100 ms. Modulating the PCP core with non-halogen-containing electron-withdrawing units, PCP-TNTCz and PCP-PyCNCz, successfully elongate the RTP lifetime to 313.59 and 528.00 ms, respectively, the afterglow of which is visible for several seconds under ambient conditions. The PCP-TNTCz and PCP-PyCNCz enantiomers display excellent circular polarized luminescence with dissymmetry factors as high as -1.2×10-2 in toluene solutions, and decent RTP lifetime of around 300 ms for PCP-TNTCz enantiomers in crystalline state.

Abstract
Background This study aimed to compare the safety and efficacy of transradial access (TRA) with transfemoral access (TFA) chemoembolization in treatment of hepatocellular carcinoma (HCC). Methods HCC patients who were late for curative treatment on initial diagnosis or HCC patients who had undergone one or several rounds of transarterial chemoembolization (TACE) were enrolled. The clinical and angiographic characteristics, the procedure related details, and the follow-up data from patients who underwent TRA and TFA were analyzed and compared. Results In total, 112 patients undergoing 160 TRA-TACE and 107 patients undergoing 163 TFA-TACE were included. The technical success rate of TRA was 95.0% and that of TFA was 98.8% (P=0.102). In the TFA-TACE group, 5.5% of cases suffered access site-related complications, including 6 with minor bleeding and 3 with severe bleeding or pseudoaneurysm. In the TRA-TACE group, 1.9% of cases underwent crossover to femoral access for selective cannulation failure. The rate of radial artery occlusion (RAO) was 2.7% (3 of 112 patients), and none of the RAO patients suffered paresthesia, pain at the site of occlusion, hand function loss or distal ischemia. Comparing patients with/without access site-related complications in the TFA-TACE group, there was a statistical difference in patient age and in the percentage of patient with a PT time >15 s (72.6% vs. 57.1%, P<0.001; 44.4% vs. 11.7%, P=0.022). Conclusions TRA is a safe and effective method for patients undergoing TACE. Compared with TFA, TRA may reduce the occurrence of access site-related bleeding and vascular complications. TRA-TACE may especially benefit older patients or those with a longer prothrombin time (PT).

Abstract
Circularly polarized organic light-emitting diodes (CP-OLEDs) are particularly favorable for the direct generation of CP light, and they demonstrate a promising application in 3D display. However, up to now, such CP devices have suffered from low brightness, insufficient efficiency, and serious efficiency roll-off. In this study, a pair of octahydro-binaphthol (OBN)-based chiral emitting enantiomers, (R/S)-OBN-Cz, are developed by ingeniously merging a chiral source and a luminophore skeleton. These chirality-acceptor-donor (C-A-D)-type and rod-like compounds concurrently generate thermally activated delayed fluorescence with a small ΔEST of 0.037 eV, as well as a high photoluminescence quantum yield of 92% and intense circularly polarized photoluminescence with dissymmetry factors (|gPL |) of ≈2.0 × 10-3 in thin films. The CP-OLEDs based on (R/S)-OBN-Cz enantiomers not only display obvious circularly polarized electroluminescence signals with a |gEL | of ≈2.0 × 10-3 , but also exhibit superior efficiencies with maximum external quantum efficiency (EQEmax ) up to 32.6% and extremely low efficiency roll-off with an EQE of 30.6% at 5000 cd m-2 , which are the best performances among the reported CP devices to date.

Abstract
Chiral materials with circularly polarized luminescence (CPL) are potentially applicable for 3D displays. In this study, by decorating the pyridinyl-helicene ligands with -CF3 and -F groups, the platinahelicene enantiomers featured superior configurational stability, as well as high sublimation yield (>90 %) and clear CPPL properties, with dissymmetry factors (|gPL |) of approximately 3.7×10-3 in solution and about 4.1×10-3 in doped film. The evaporated circularly polarized phosphorescent organic light-emitting diodes (CP-PhOLEDs) with two enantiomers as emitters exhibited symmetric CPEL signals with |gEL | of (1.1-1.6)×10-3 and decent device performances, achieving a maximum brightness of 11 590 cd m-2 , a maximum external quantum efficiency up to 18.81 %, which are the highest values among the reported devices based on chiral phosphorescent PtII complexes. To suppress the effect of reverse CPEL signal from the cathode reflection, the further implementation of semitransparent aluminum/silver cathode successfully boosts up the |gEL | by over three times to 5.1×10-3 .

Abstract
Bis(diphenylphorothioyl)amide (Stpip) containing phosphor-sulfur (P═S) bonds was used as an ancillary ligand for three pure green iridium(III) emitters Ir1, Ir2, and Ir3, which were synthesized in few minutes at room temperature with high reaction yields above 70%. All these complexes show good thermal stability and excellent sublimation yields of around 80-90%, which are considered beneficial for industry practical production and organic light-emitting diode (OLED) fabrication. The emission profiles of these complexes meet the green standards of CIE1931 with coordinates of (0.33, 0.63), (0.33, 0.62), and (0.34, 0.62), respectively, and high photoluminescence quantum yields of up to 98% are achieved. Utilizing these complexes as emissive dopants, these OLEDs exhibited high current efficiency up to 91.94 cd A-1, external quantum efficiency up to 26.52%, and power efficiency up to 92.60 lm W-1 with very small efficiency roll-off, without adopting internal or external out-coupling methods. These results indicate that Stpip is a potentially suitable ligand scaffold for highly efficient phosphorescent Ir(III) emitters that endow corresponding OLEDs with high efficiency and small roll-off.

Abstract
The lack of efficient blue-emitting materials is one of the most important issues faced when extending the application of organic light-emitting diodes (OLEDs). Therefore, in this study, the ancillary ligand bis(diphenylphorothioyl)amide (Stpip) was utilized in iridium(iii) complexes with 2-(2,4-difluorophenyl)pyridine (dfppy) and 2-(2,4-difluorophenyl)pyrimidine (dfppm) as the main ligands, respectively. The two complexes, (dfppy)2Ir(Stpip) and (dfppm)2Ir(Stpip), exhibit sky-blue emission peaks at 466 and 474 nm with photoluminescence quantum yields of 12% and 89%, respectively. Due to the strong coordination capability between sulfur and iridium atoms, both complexes can be prepared with extremely high production yields under mild conditions. Furthermore, a double light-emitting layer device using (dfppm)2Ir(Stpip) as the emitter exhibits a maximum external quantum efficiency (EQEmax) of 19.4% with Commission Internationale de l'Eclairage (CIE) coordinates of (0.13, 0.27). Specifically, the EQE remains at 19.2% at a practical brightness of 1000 cd m-2, indicating an inappreciable efficiency roll-off.

Abstract
Aiming to balance the injection and transport of electrons and holes, nitrogen heterocycle and 1,3,4-oxadiazole derivatives were introduced in iridium(iii) complexes to obtain organic light-emitting diodes (OLEDs) with high performances. Thus, two novel Ir(iii) complexes (Ir(tfmphpm)2(pop) and Ir(tfmppm)2(pop)) with green emissions using 2-(3,5-bis(trifluoromethyl)phenyl)pyrimidine (tfmphpm) and 2-(2,6-bis(trifluoromethyl)pyridin-4-yl)pyrimidine (tfmppm) as cyclometalating ligands, and 2-(5-phenyl-1,3,4-oxadiazol-2-yl)phenol (pop) as an ancillary ligand were synthesized. Both emitters show high photoluminescence efficiencies up to 94% and good electron mobility. The devices using two emitters with the structure of ITO (indium-tin-oxide)/MoO3 (molybdenum oxide, 5 nm)/TAPC (di-[4-(N,N-ditolyl-amino)-phenyl]cyclohexane, 30 nm)/mCP (1,3-bis(9H-carbazol-9-yl)benzene, 5 nm)/Ir(iii) complexes (6 wt%) : PPO21 (3-(diphenylphosphoryl)-9-(4-(diphenylphosphoryl)phenyl)-9H-carbazole, 10 nm)/TmPyPB (1,3,5-tri(m-pyrid-3-yl-phenyl) benzene, 40 nm)/LiF (1 nm)/Al (100 nm) display good electroluminescence performances with a maximum luminance of 48 981 cd m-2, a maximum current efficiency of 92.79 cd A-1 and a maximum external quantum efficiency up to 31.8%, respectively, and the efficiency roll-off ratio is low, suggesting that they have potential application in OLEDs.

Abstract
PURPOSE To evaluate the safety and efficacy of iodine-125 (125I) seed strand implantation in combination with transarterial chemoembolization for the treatment of hepatitis B-related unresectable hepatocellular carcinoma (HCC) with portal vein invasion. MATERIALS AND METHODS From January 2013 to June 2016, 76 HCC patients with type II tumor thrombus were included in this single-center retrospective study. Twenty patients underwent 125I seed strand implantation combined with transarterial chemoembolization (group A; n = 20), while 56 patients underwent transarterial chemoembolization alone (group B; n = 56). The procedure-related and radiation complications were assessed. Overall survivals were compared by propensity-score analysis. RESULTS The technique was successfully performed in all patients. The mean intended dose (r = 10 mm; z = 0; 240 days) was 62.6 ± 1.8 Gy. No grade 3 or 4 adverse events related to the procedure occurred in either group. After propensity-score-matching analysis, 19 patients were selected into each group, respectively. In the propensity-matching cohort, the median overall survival time was significantly longer in group A than in the group B (19 pairs; 28.0 ± 2.4 vs 8.7 ± 0.4 mo; P = .001). Treatment strategy, arterioportal shunt, and number of transarterial chemoembolization sessions were significant predictors of favorable overall survival time. CONCLUSIONS 125I seed strand implantation combined with transarterial chemoembolization is a safe and effective treatment for HCC patients with portal vein invasion.

Abstract
OBJECTIVE To investigate the safety and efficacy of radiofrequency ablation combined with transarterial chemoembolization in patients with specially located small hepatocellular carcinoma. MATERIALS AND METHODS Between March 2014 and March 2017, a total of 26 patients with 26 lesions (10 perivascular, 6 subdiaphragmatic, 5 subcapsular, 5 perivascular, and subdiaphragmatic location; mean diameter 2.12 (0.62) cm), who received radiofrequency ablation-transarterial chemoembolization treatment, were retrospectively analyzed. Local tumor response was assessed by computed tomography/magnetic resonance imaging 1 month after the procedure. Tumor-free survival was also assessed according to the modified Response Evaluation Criteria in Solid Tumors. Complications were evaluated according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (version 4.0). RESULTS Complete response was achieved in all patients 1 month after the procedure. During a median follow-up duration of 16.76 months (95% confidence interval: 7.78-25.73 months), local tumor recurrence occurred in 2 patients and new intrahepatic lesions developed in 7 patients. The 1-, 2-, and 3-year cumulative local tumor progression rates were 3.84%, 7.69%, and 7.69%, respectively. The median tumor-free survival duration was 21.96 months (95% confidence interval: 17.58-26.34 months). The 1-, 2-, and 3-year tumor-free survival rates were 67.4%, 46.1%, and 39.3%, respectively. CONCLUSION The radiofrequency ablation-transarterial chemoembolization combination therapy appears to be safe and effective and might be a treatment option for specially located small hepatocellular carcinoma lesions that have a risk of incomplete ablation or major complications.

Abstract
AIM To evaluate the safety and efficacy of combined endovascular brachytherapy (EVBT), transarterial chemoembolization (TACE), and sorafenib to treat hepatocellular carcinoma (HCC) patients with main portal vein tumor thrombus (MPVTT).
METHODS This single-center retrospective study involved 68 patients with unresectable HCC or those who were unfit for liver transplantation and percutaneous frequency ablation according to the BCLC classification. All patients had Child-Pugh classification grade A or B, Eastern Cooperative Oncology Group (ECOG) performance status of 0-2, and MPVTT. The patients received either EVBT with stent placement, TACE, and sorafenib (group A, n = 37), or TACE with sorafenib (group B, n = 31). The time to progression (TTP) and overall survival (OS) were evaluated by propensity score analysis.
RESULTS In the entire cohort, the 6-, 12-, and 24-mo survival rates were 88.9%, 54.3%, and 14.1% in group A, and 45.8%, 0%, and 0% in group B, respectively (P < 0.001). The median TTP and OS were significantly longer in group A than group B (TTP: 9.0 mo vs 3.4 mo, P < 0.001; OS: 12.3 mo vs 5.2 mo, P < 0.001). In the propensity score-matched cohort, the median OS was longer in group A than in group B (10.3 mo vs 6.0 mo, P < 0.001). Similarly, the median TTP was longer in group A than in group B (9.0 mo vs 3.4 mo, P < 0.001). Multivariate Cox analysis revealed that the EVBT combined with stent placement, TACE, and sorafenib strategy was an independent predictor of favorable OS (HR = 0.18, P < 0.001).
CONCLUSION EVBT combined with stent placement, TACE, and sorafenib might be a safe and effective palliative treatment option for MPVTT.

Abstract
Hepatocellular carcinoma (HCC) patients with main portal vein tumor thrombus have a median survival time of only about 4 months. We therefore compared the safety and efficacy of endovascular brachytherapy (EVBT) and sequential three-dimensional conformal radiotherapy (3-DCRT). From a cohort of 176 patients, we treated 123 with EVBT using iodine-125 seed strands (group A) and the remaining 53 with sequential 3-DCRT (group B). Overall survival, progression free survival and stent patency characteristics were compared between the two groups. Our analysis demonstrated a median survival of 11.7 ± 1.2 months in group A versus 9.5 ± 1.8 months in group B (p = 0.002). The median progression free survival was 5.3 ± 0.7 months in groupA versus 4.4 ± 0.4 months in group B (p = 0.010). The median stent patency period was 10.3 ± 1.1 months in group A versus 8.7 ± 0.7 months in group B (p = 0.003). Therefore, as compared to sequential 3-DCRT, EVBT combined with portal vein stenting and TACE improved overall survival of HCC patients with main portal vein tumor thrombus.

Abstract
PURPOSE To investigate the safety and feasibility of intraluminal brachytherapy using 125I seed strand for locally advanced pancreatic ductal adenocarcinoma with obstructive jaundice. METHODS AND MATERIALS From January 2010 to February 2015, 18 consecutive patients diagnosed with locally advanced, nonmetastatic, inoperable pancreatic ductal adenocarcinoma with obstructive jaundice were enrolled and underwent intraluminal brachytherapy using 125I seed strand. Dose calculation was performed using a software. The procedure-related and radiation complications were assessed. Obstruction-free survival and overall survival were calculated using the Kaplan-Meier method. RESULTS The technique successful rate of 125I seed strand implantation was 100%. Successful bile drainage was achieved in all patients. The estimated mean accumulating dose (R = 5 mm, z = 0, 240 days) was 167.2 Gy, from 164.19 to 170.05 Gy. Two patients had adverse event of Grade 3, one of Grade 4. Stent dysfunction occurred in 1/18 (5.6%) patients. The mean and median obstruction-free survival time were 10.61 months (95% confidence interval [CI]: 7.04, 14.18) and 7.26 months (95% CI: 2.14, 12.38). The mean and median overall survival time were 11.91 months (95% CI: 7.39, 16.43) and 7.26 months (95% CI: 2.14, 12.38). CONCLUSIONS Intraluminal brachytherapy using 125I seed strand may be consider as a safe treatment option for the therapy of locally advanced pancreatic duct adenocarcinoma complicated by obstructive jaundice with acceptable complication rates.

Abstract
The developmental process of epithelial-mesenchymal transition (EMT) occurs when epithelial cells acquire invasive mesenchymal cell characteristics, and the activation of this process has been indicated to be involved in tumor progression. EMT could be induced by growth factors, cytokines and matrix metalloproteinases (MMPs). sphingosine-1-phosphate (S1P) is a biologically-active lipid that plays an important role in cancer metastasis. S1P also contributes to the activation of EMT. However, the mechanism underlying S1P-induced EMT is unclear. Increased evidence has demonstrated that the cell surface glycocalyx is closed associated with S1P and plays an important role in tumor progression, suggesting that S1P-induced EMT could be Snail-MMP signaling-dependent. Thus, we hypothesize that an S1P-glycocalyx-Snail-MMP signaling axis mediates S1P-induced EMT. This is an essential step towards improved understanding of the underlying mechanism involved in S1P-regulted EMT, and the development of novel diagnostic and anticancer therapeutic strategies.

Abstract
Meta-analyses have revealed many positive associations between gene variants and susceptibility to chronic obstructive pulmonary disease (COPD). However, some of those positive results may be false positives. Therefore, we investigated the genetic polymorphisms associated with COPD risk and determined their diagnostic value. We extracted the odds ratio (OR) and 95% confidence interval for each polymorphism from published meta-analyses concerning gene variants and COPD susceptibility in October 2014, subsequently we calculated false-positive report probabilities (FPRPs) for statistically significant associations (P value < 0.05). We determined the diagnostic value of the true positive polymorphisms of COPD using the Meta-DiSc software. Twenty-five gene polymorphisms were significantly associated with COPD risk. The FPRP test results were as follows: 1) when the prior probability was 0.001 and the OR was 1.5, ADAM33 rs612709, CHRNA3/5 rs1051730, CHRNA3/5 rs8034191, CHRNA3/5 rs16969968, and TGFB1 rs1800470 were truly associated with COPD risk (FPRP < 0.2); 2) when the prior probability was 0.000001 and the OR was 1.5, all the variants except TGFB1 rs1800470 remained noteworthy; and 3) when the probability was 0.000001 and the OR was 1.2, ADAM33 rs612709 and CHRNA3/5 rs1051730 remained true positives. Unfortunately, the results of the diagnostic accuracy meta-analyses suggested that none of the variants had high value for COPD diagnosis.

Abstract
PURPOSE To evaluate the safety and efficacy of microwave (MW) ablation combined with transarterial chemoembolization in a single stage for the treatment of large (≥ 5 cm) hepatocellular carcinoma (HCC). MATERIALS AND METHODS From March 2013 to January 2015, 66 patients (54 men and 12 women; mean age, 54 y; range, 29-83 y) with 72 large HCC lesions were included in this study. Eighteen (27.3%) had Barcelona Clinic Liver Cancer class B disease, and 48 (72.7%) had class C disease. Seventy-nine percent of patients (n = 52) had hepatitis B virus infection. The average tumor size was 9.0 cm ± 3.9, ranging from 5 to 19 cm. MW ablation was performed under ultrasound guidance, immediately followed by chemoembolization. Local tumor response, progression-free survival (PFS), and overall survival (OS) were assessed. RESULTS The technique was successfully performed in all patients. Complete response (CR) was achieved in 28 cases (42.4%), and partial response (PR) was achieved in 34 cases (51.5%) at 1 month after the procedure. The objective response rate (ie, CR plus PR) was 93.9%. Median PFS and OS times were 9 months and 21 months, respectively. The 6-, 12-, and 18-month OS rates were 93.9%, 85.3%, and 66.6%, respectively. Hemorrhage was detected in three patients and arteriovenous fistula in two patients after MW ablation; all were promptly treated with embolization. There were no liver abscesses, bile-duct injuries, or other major procedure-related complications. CONCLUSIONS MW ablation immediately followed by chemoembolization is safe and effective in the treatment of large HCC lesions.

Abstract
Aim To investigate whether ultrasound-guided RNA interference (RNAi) targeting hypoxia-inducible factor-1alpha (HIF-1α) can enhance the efficacy of transarterial chemoembolization (TACE) in treating hepatocellular carcinoma. Materials and methods Rats with orthotopic hepatocellular carcinoma were randomized to four groups and treated as follows: 1) control; 2) siHIF-1α; 3) TACE; 4) siHIF-1α+TACE. Lentivirus (4×108 transfection units) with or without small interfering RNA (siRNA) expression in 0.6 mL transduction reagent was injected into tumors using a standard 1 mL syringe under ultrasonic guidance. In the siHIF-1α+TACE and siHIF-1α groups, rats received siRNA-expressing lentivirus; the rats in the TACE and control groups received lentivirus without siRNA. TACE was performed by placing a microcatheter into the gastroduodenal artery. Results The median survival time, body weight, and tumor volume of the siHIF-1α+TACE group were better than those of the TACE, siHIF-1α, and control groups. A comparative analysis of the different treatment groups demonstrated that HIF-1α RNAi could downregulate the levels of HIF-1α and VEGF, inhibit tumor angiogenesis, and lessen metastases; all of these effects were enhanced by TACE. Conclusion HIF-1α RNAi, which was administered in vivo in liver tumors under ultrasound guidance, improved the efficacy of TACE in treating hepatocellular carcinoma in an animal model.

Abstract
Acute ischemic stroke is a significant cause of high morbidity and mortality in the aging population globally. However, current therapeutic strategies for acute ischemic stroke are limited. Atherosclerotic plaque is considered an independent risk factor for acute ischemic stroke. To identify biomarkers for carotid atheromatous plaque, bioinformatics analysis of the gene microarray data of plaque and intact tissue from individuals was performed. Differentially expressed genes (DEGs) were identified using the Multtest and Limma packages of R language, including 56 downregulated and 69 upregulated DEGs. Enriched microRNA (miRNA or miR) DEGs networks were generated using WebGestalt software and the STRING databases, and the miRNAs were validated using serum from acute ischemic stroke patients with reverse transcription quantitative PCR (RT‑qPCR). Four confirmed differentially expressed miRNAs (miR‑9, ‑22, ‑23 and ‑125) were associated with 28 upregulated DEGs, and 7 miRNAs (miR‑9, ‑30, ‑33, ‑124, ‑181, ‑218 and ‑330) were associated with 25 downregulated DEGs. Gene ontology (GO) function suggested that the confirmed miRNA‑targeted DEGs predominantly associated with signal transduction, the circulatory system, biological adhesion, striated muscle contraction, wound healing and the immune system. The confirmed miRNA‑targeted genes identified serve as potential therapeutic targets for acute ischemic stroke.

Abstract
Aim To retrospectively evaluate the safety and efficacy of ultrasound-guided percutaneous microwave ablation (MWA) combined with simultaneous transarterial chemoembolization (TACE) in the treatment of patients with advanced intrahepatic cholangiocarcinoma (ICC). Methods All patients treated with ultrasound-guided percutaneous MWA combined with simultaneous TACE for advanced ICC at our institution were included. Posttreatment contrast-enhanced computed tomography and/or magnetic resonance imaging were retrieved and reviewed for tumor response to the treatment. Routine laboratory studies, including hematology and liver function tests were collected and analyzed. Procedure-related complications were reviewed and survival rates were analyzed. Results From January 2011 to December 2014, a total of 26 advanced ICC patients were treated at our single institute with ultrasound-guided percutaneous MWA combined with simultaneous TACE. There were 15 males and eleven females with an average age of 57.9±10.4 years (range, 43–75 years). Of 26 patients, 20 (76.9%) patients were newly diagnosed advanced ICC without any treatment, and six (23.1%) were recurrent and treated with surgical resection of the original tumor. The complete ablation rate was 92.3% (36/39 lesions) for advanced ICC. There were no major complications observed. There was no death directly from the treatment. Median progression-free survival and overall survival were 6.2 and 19.5 months, respectively. The 6-, 12-, and 24-month survival rates were 88.5%, 69.2%, and 61.5%, respectively. Conclusion The study suggests that ultrasound-guided percutaneous MWA combined with simultaneous TACE therapy can be performed safely in all patients with advanced ICC. The complete ablation rate was high and there was no major complication. The overall 24-month survival was 61.5%.
