Abstract
PURPOSE Detecting tumor progression of glioma continues to pose a formidable challenge. The role of fibroblast activation protein (FAP) in gliomas has been demonstrated to facilitate tumor progression. Glioma-circulating biomarkers have not yet been used in clinical practice. This study seeks to evaluate the feasibility of glioma detection through the utilization of a serum FAP marker. METHODS We adopted enzyme-linked immunosorbent assay (ELISA) technique to quantify the relative FAP level of serum autoantibodies in a cohort of 87 gliomas. The correlation between preoperative serum autoantibody relative FAP levels and postoperative pathology, including molecular pathology was investigated. A series of FAP tests were conducted on 33 cases of malignant gliomas in order to ascertain their efficacy in monitoring the progression of the disease in relation to imaging observations. To validate the presence of FAP expression in tumors, immunohistochemistry was conducted on four gliomas employing a FAP-specific antibody. Additionally, the investigation encompassed the correlation between postoperative tumor burden, as assessed through volumetric analysis, and the relative FAP level of serum autoantibodies. RESULTS A considerable proportion of gliomas exhibited a significantly increased level of serum autoantibody relative FAP level. This elevation was closely associated with both histopathology and molecular pathology, and demonstrated longitudinal fluctuations and variations corresponding to the progression of the disease The correlation between the rise in serum autoantibody relative FAP level and tumor progression and/or exacerbation of symptoms was observed. CONCLUSIONS The measurement of serum autoantibody relative FAP level can be used to detect the disease as a valuable biomarker. The combined utilization of its detection alongside MR imaging has the potential to facilitate a more accurate and prompt diagnosis.

Abstract
Background Veno-venous extracorporeal membrane oxygenation (ECMO) was successfully performed for the rescue of an adult patient with severe acute respiratory distress syndrome (ARDS) induced by fulminant psittacosis, and then a near-fatal pulmonary embolism (PE) and cardiac arrest (CA) of the same patient was cured through catheter-directed thrombolysis. Case presentation A 51-year-old female patient was admitted to the hospital on September 10, 2021 due to slurred speech, weakness in lower limbs, dizziness, and nausea. Subsequently, she developed confusion and was transferred to the intensive care unit (ICU), where she received anti-shock, antibiotics, invasive mechanical ventilation (IMV), and veno-venous ECMO due to the diagnosis of severe pneumonia, severe ARDS, and septic shock based on comprehensive physical examination, laboratory tests, and imaging findings. The metagenomic next-gengeration sequencing (m-NGS) in the bronchoalveolar lavage fluid (BALF) suggested that the pathogen was chlamydia psittaci, so the antibiotics were adjusted to doxycycline combined with azithromycin. After withdrawal from ECMO, ultrasound (US) re-examination of the left lower limb revealed inter-muscular vein thrombosis, following which heparin was replaced by subcutaneous injection of 0.4ml enoxaparin sodium twice daily for anti-coagulation therapy. After withdrawal from IMV, the patient suffered sudden CA and successful cardiopulmonary resuscitation (CPR), and emergency pulmonary angiography (PA) was performed to show bilateral main pulmonary artery embolism. After immediate catheter-directed thrombolysis and placement of an inferior vena cava filter, the patient's condition gradually stabilized. Conclusions Veno-venous ECMO can be successfully performed as an emergency life-saving treatment for patients with severe ARDS induced by fulminant psittacosis, and during ECMO regular examinations should be conducted to detect and manage thrombosis in time, thereby avoiding the occurrence of near-fatal PE and CA.

Abstract
1,3-Functionalized cyclobutane structural motifs are ubiquitous in natural products and pharmaceuticals. Photoinduced alkylation of bicyclo[1.1.0]butanes (BCBs) offers a step-economical strategy for accessing 1,3-functionalized cyclobutane motifs. Herein, we disclose a general and mild photocatalytic protocol of bromoallylation and alkylation of BCBs in a metal, additive-free manner by using the same photocatalyst, 2-isopropylthioxanthone, in different catalytic roles. Furthermore, the synthetic utility of these products was illustrated in the synthesis of various valuable and complex cyclobutane derivatives.

Abstract
Objectives: The aim of this study was to investigate the effectiveness of narrative therapy in reducing work pressure and improving health behavior among clinical and anesthesia frontline nurses. Methods: We used convenience sampling to select clinical and anesthesiology department nurses from hospitals between May 2019 and May 2021. We used a nursing knowledge-attitude-behavior questionnaire to assess the status of nurses and assess the effectiveness of the narrative therapy intervention. We analyzed our data using SPSS and Smart PLS. Results: We found statistically significant differences in scores on the Competence Scale (NCS) and the Nursing Caring Characters Assessment Tool (NCCAT) (p<.05). The average scores of items in each dimension of clinical and anesthesiology department narrative nursing knowledge and behavior were: knowledge score (3.67±0.52), attitude score (5.48±0.62), and behavior score (4.74±0.77). Conclusion: The ADDIE-based narrative nursing training program improved nurses' narrative nursing ability and humanistic care quality, reducing work pressure and promoting health behavior. These findings highlight the importance of narrative therapy in clinical practice for frontline nurses.

Abstract
The first carbonatotellurites, AKTeO2(CO3) (A = Li, Na), have been successfully synthesized by using boric acid as the mineralizer. AKTeO2(CO3) (A = Li, Na) crystallize in the monoclinic space group P21/n (no. 14), and their structures exhibit the novel zero-dimensional (0D) [Te2C2O10]4- clusters, in which two [TeO4]4- groups form a [Te2O6]4- dimer via edge-sharing, with each side of the dimer attached by a [CO3]2- group via a Te-O-C bridge. The alkali metal cations occupy the voids between the 0D clusters and maintain the charge balance. The ultraviolet-visible-near-infrared diffuse reflectance spectra show that the short absorption cut-off edges of LiKTeO2(CO3) (LKTC) and NaKTeO2(CO3) (NKTC) are 248 and 240 nm, respectively, and LKTC exhibits the largest experimental band gap (4.58 eV) among all of the tellurites containing the π-conjugated anionic groups reported. Theoretical calculations revealed that they exhibit moderate birefringences of 0.029 and 0.040@1064 nm, respectively.

Abstract
In this study, we aimed to explore whether lymphocyte–C-reactive protein ratio (LCR) can differentiate disease severity of coronavirus disease 2019 (COVID-19) patients and its value as an assistant screening tool for admission to hospital and intensive care unit (ICU). A total of 184 adult COVID-19 patients from the COVID-19 Treatment Center in Heilongjiang Province at the First Affiliated Hospital of Harbin Medical University between January 2020 and March 2021 were included in this study. Patients were divided into asymptomatic infection group, mild group, moderate group, severe group, and critical group according to the Diagnosis and Treatment of New Coronavirus Pneumonia (ninth edition). Demographic and clinical data including gender, age, comorbidities, severity of COVID-19, white blood cell count (WBC), neutrophil proportion (NEUT%), lymphocyte count (LYMPH), lymphocyte percentage (LYM%), red blood cell distribution width (RDW), platelet (PLT), C-reactive protein (CRP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), serum creatinine (SCr), albumin (ALB), total bilirubin (TB), direct bilirubin (DBIL), indirect bilirubin (IBIL), and D-dimer were obtained and collated from medical records at admission, from which sequential organ failure assessment (SOFA) score and LCR were calculated, and all the above indicators were compared among the groups. Multiple clinical parameters, including LYMPH, CRP, and LCR, showed significant differences among the groups. The related factors to classify COVID-19 patients into moderate, severe, and critical groups included age, number of comorbidities, WBC, LCR, and AST. Among these factors, the number of comorbidities showed the greatest effect, and only WBC and LCR were protective factors. The area under the receiver operating characteristic (ROC) curve of LCR to classify COVID-19 patients into moderate, severe, and critical groups was 0.176. The cutoff value of LCR and the sensitivity and specificity of the ROC curve were 1,780.7050 and 84.6% and 66.2%, respectively. The related factors to classify COVID-19 patients into severe and critical groups included the number of comorbidities, PLT, LCR, and SOFA score. Among these factors, SOFA score showed the greatest effect, and LCR was the only protective factor. The area under the ROC curve of LCR to classify COVID-19 patients into severe and critical groups was 0.106. The cutoff value of LCR and the sensitivity and specificity of the ROC curve were 571.2200 and 81.3% and 90.0%, respectively. In summary, LCR can differentiate disease severity of COVID-19 patients and serve as a simple and objective assistant screening tool for hospital and ICU admission.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) has been far more devastating than expected, showing no signs of slowing down at present. Heilongjiang Province is the most northeastern province of China, and has cold weather for nearly half a year and an annual temperature difference of more than 60ºC, which increases the underlying morbidity associated with pulmonary diseases, and thus leads to lung dysfunction. The demographic features and laboratory parameters of COVID-19 deceased patients in Heilongjiang Province, China with such climatic characteristics are still not clearly illustrated.
AIM To illustrate the demographic features and laboratory parameters of COVID-19 deceased patients in Heilongjiang Province by comparing with those of surviving severe and critically ill cases.
METHODS COVID-19 deceased patients from different hospitals in Heilongjiang Province were included in this retrospective study and compared their characteristics with those of surviving severe and critically ill cases in the COVID-19 treatment center of the First Affiliated Hospital of Harbin Medical University. The surviving patients were divided into severe group and critically ill group according to the Diagnosis and Treatment of New Coronavirus Pneumonia (the seventh edition). Demographic data were collected and recorded upon admission. Laboratory parameters were obtained from the medical records, and then compared among the groups.
RESULTS Twelve COVID-19 deceased patients, 27 severe cases and 26 critically ill cases were enrolled in this retrospective study. No differences in age, gender, and number of comorbidities between groups were found. Neutrophil percentage (NEUT%), platelet (PLT), C-reactive protein (CRP), creatine kinase isoenzyme (CK-MB), serum troponin I (TNI) and brain natriuretic peptides (BNP) showed significant differences among the groups (P = 0.020, P = 0.001, P < 0.001, P = 0.001, P < 0.001, P < 0.001, respectively). The increase of CRP, D-dimer and NEUT% levels, as well as the decrease of lymphocyte count (LYMPH) and PLT counts, showed significant correlation with death of COVID-19 patients (P = 0.023, P = 0.008, P = 0.045, P = 0.020, P = 0.015, respectively).
CONCLUSION Compared with surviving severe and critically ill cases, no special demographic features of COVID-19 deceased patients were observed, while some laboratory parameters including NEUT%, PLT, CRP, CK-MB, TNI and BNP showed significant differences. COVID-19 deceased patients had higher CRP, D-dimer and NEUT% levels and lower LYMPH and PLT counts.

Abstract
The sequencing batch reactor (SBR) activated sludge process is a well-established technology for sewage treatment. One of the drawbacks of SBRs, however, total nitrogen (TN) removals is insufficient. By means of introducing four improvements, including semi-fixed biofilm carrier, sludge elevation mixing and change for the mode of influent and effluent, compliant standard for TN discharge was obtained in this novel SBR configuration during low- and high-strength sewage load. To illustrate the microbial compositions and functions of the attached biofilm on semi-fixed carrier and the suspended aggregates, as well as the nitrogen removal pathway, high throughput 16S rRNA gene amplicon sequencing, PICRUSt2 algorithm, and KEGG database were applied. The results revealed that (i) the microbial communities from suspended aggregates and biofilm samples were significantly different from each other; (ii) during low-strength sewage loads, TN removal was mainly by nitrification-denitrification. The suspended aggregates was responsible for denitrification, while the biofilm was focused on ammonium oxidation; (iii) during high-strength sewage loads, function of nitrate reductase from suspended aggregates was faded, and anammox and N assimilation by biofilm became dominant. Meanwhile, TN removal referring to the formation of L-glutamine via assimilation was the main pathway.

Abstract
This work presents an artificial intelligence enhanced orbital angular momentum (OAM) data transmission system. This system enables encoded data retrieval from speckle patterns generated by an incident beam carrying different topological charges (TCs) at the distal end of a multi-mode fiber. An appropriately trained network is shown to support up to 100 different fractional TCs in parallel with TC intervals as small as 0.01, thus overcoming the problems with previous methods that only supported a few modes and could not use small TC intervals. Additionally, an approach using multiple parallel neural networks is proposed that can increase the system's channel capacity without increasing individual network complexity. When compared with a single network, multiple parallel networks can achieve the better performance with reduced training data requirements, which is beneficial in saving computational capacity while also expanding the network bandwidth. Finally, we demonstrate high-fidelity image transmission using a 16-bit system and four parallel 14-bit systems via OAM mode multiplexing through a 1-km-long commercial multi-mode fiber (MMF).

Abstract
Objective: To explore the medium-long term efficacy of transjugular intrahepatic portosystemic shunt (TIPS) for gastrointestinal hemorrhage in patients with idiopathic non-cirrhotic portal hypertension (INCPH). Methods: From March 2013 to July 2018, clinical data of 13 INCPH patients, including 5 males, 8 females,with gastrointestinal hemorrhage were retrospectively analyzed, who were diagnosed at the First Affiliated Hospital of Zhengzhou University, Anyang Fifth People' s Hospital and Yuncheng Central Hospital. All patients received TIPS treatment. The general information, postoperative survival rate, the incidence of rebleeding, shunt dysfunction rate, and incidence of hepatic encephalopathy were analyzed. Results: All 13 patients with INCPH completed TIPS successfully with an average age of 45±8 (33 to 59) years. The hepatic venous pressure gradient (HVPG) decreased from 20.0-26.0 (22.6±1.9) mmHg before procedure to 8.0-14.0 (9.4±3.2) mmHg after. The median follow-up time was 44±7 (31 to 53) months. One patient died of liver failure 27 months after TIPS. Hepatic encephalopathy occurred cumulatively in 1 case (1/13), 1 case (1/13) and 1 case (1/13) in 12, 24 and 36 months after TIPS. Stent restenosis occurred cumulatively in 2 cases (2/13), 3 cases (3/13) and 3 cases (3/13) in 12, 24 and 36 months after TIPS. Portal vein thrombosis occurred cumulatively in 2 cases (2/13), and no primary liver cancer developed. Conclusions: TIPS is safe and effective in the treatment of INCPH with gastrointestinal bleeding with favorable medium-long term outcome.

Abstract
Described herein is a novel Brønsted acid catalyzed intramolecular hydroalkoxylation/Claisen rearrangement, allowing the practical and atom-economic synthesis of a range of valuable spirolactams from readily available ynamides in generally good to excellent yields with excellent diastereoselectivities and broad substrate scope. Importantly, an unexpected dearomatization of nonactivated arenes and heteroaromatic compounds is involved in this tandem sequence. Moreover, an asymmetric version of this tandem cyclization was also achieved by efficient kinetic resolution by chiral phosphoric acid catalysis. In addition, the [3,3]-rearrangement is shown to be kinetically preferred over the related [1,3]-rearrangement by theoretical calculations.

Abstract
Aims: The aim of this study was to identify the immune- and locus-associated genes in pancreatic ductal adenocarcinoma and evaluate their value in prognosis. Methods: The pancreatic ductal adenocarcinoma stromal and immune scores were calculated with the estimation of stromal and immune cells in malignant tumor tissues using expression data algorithm. The authors screened the differentially expressed genes to generate immune- and stromal-related differentially expressed genes. Next, the authors conducted weighted correlation network analysis to find the gene sets related to tumor sites. Results: IL1R1 and LAMA2 were identified as the site- and immune-related genes in pancreatic ductal adenocarcinoma, and their high expression in pancreatic head cancer exhibited high immune scores and predicted unfavorable prognosis. Conclusion: The authors identified IL1R1 and LAMA2 as immune- and locus-associated genes, and their high expression predicted a poor prognosis.

Abstract
To evaluate the clinical value of emergency endovascular embolization in the interventional treatment for oral hemorrhage caused by carcinoma, 32 patients with oral hemorrhage caused by carcinoma, who received emergency endovascular embolization due to unsatisfactory hemostatic effect of conventional conservative treatment in the First Affiliated Hospital of Zhengzhou University from January 2014 to December 2019, were included in this study and their clinical data, laboratory data and imaging information were retrospectively analyzed. There were 16 males and 16 females, aged (60.6±13.6) years (34-88 years). Technical successful rate of emergency endovascular embolization, immediate successful rate of controlling hemorrhage, blood pressure before and after operation, hemoglobin before and after operation, postoperative complications and recurrence rate of oral hemorrhage were statistically analyzed. Results showed that technical successful rate of operation and immediate successful rate of controlling oral hemorrhage are both 100% (32/32). Recurrent oral hemorrhage occurred in 4 patients (13%). The hemorrhagic shock symptoms of all patients were significantly improved after interventional therapy. After operation, local swelling happened in 34% (11/32) patients and intermittent local pain happened in 22% (7/32) within 24 hours; the swelling and the pain gradually disappeared from 2nd to 5th days. Mild complications of transient fever happened in 9% (3/32) patients and disappeared spontaneously in the short term. No serious complications such as blindness, cerebrovascular accident or central nervous system disturbance occurred in all patients after operations. During the whole follow-up period (1 to 12 months), a total of 8 patients died. The causes of death were progression and metastasis of carcinoma (n=4), heart failure (n=2), severe pneumonia (n=1) and respiratory failure caused by recurrent oral hemorrhage (n=1). Owing to the remarkable short-term curative effect, repeatable operation, low recurrence rate of oral hemorrhage and low incidence of complications, emergency endovascular embolization can be used in the clinical therapy and application of oral hemorrhage caused by carcinoma.

Abstract
Biofouling by the invasive golden mussel Limnoperna fortunei deleteriously affects artificial water systems, but few effective, environmentally friendly antifouling strategies exist. We propose ultrasound for control of this invasive mussel and report minimum exposure times to kill juveniles and adults at ultrasonic powers ranging 300-600 W from a fixed distance of 8.5 cm. Analysis using a PMA + RT-qPCR assay revealed the formation of tissue lesions in response to ultrasound, with gill tissue more prone to injury than adductor muscle tissue. Shell microstructure determined using scanning electron microscopy (SEM) + energy dispersive X-ray spectroscopy (EDS) is plywood-like, with a thicker shell and increased numbers of prism and nacre layers in adult mussels that provide greater resistance to ultrasound, reducing mortality and tissue lesions. Our results suggest L. fortunei biomass could be effectively reduced by ultrasound, especially for early life-history stages without, or with only immature shells.

Abstract
BACKGROUND Patients with anterior acute myocardial infarction (AMI) and left ventricular (LV) dysfunction have an increased risk of LV thrombus (LVT). In the thrombolytic era, short-term anticoagulation using low-molecular-weight heparin during hospitalization proved to significantly reduce LVT formation, but, the effect of this prophylactic approach remains unclear in the current era. Therefore, we conducted a study to evaluate the effects of post-procedural anticoagulation (PPAC) using enoxaparin in addition to dual antiplatelet therapy (DAPT) after primary percutaneous coronary intervention (PCI) in such patients.Methods and Results:A total of 426 anterior AMI patients with LV ejection fraction ≤40% were retrospectively enrolled and classified into 2 groups based on whether they received PPAC (enoxaparin SC for at least 7 days). All patients received primary PCI and DAPT. The primary endpoint was definite LVT at 30 days diagnosed by echocardiography. The secondary endpoints were 30-day mortality, embolic events, and major bleeding events. PPAC was independently associated with a lower incidence of LVT (odds ratio 0.139, 95% confidence interval 0.032-0.606, P=0.009). The 30-day mortality, embolic events, and major bleeding events were not statistically different between groups. CONCLUSIONS Short-term PPAC using enoxaparin after primary PCI may be an effective and safe way to prevent LVT in patients with anterior AMI and LV dysfunction.

Abstract
Ultraviolet (UV) disinfection during water supply treatment aims to reduce the number of bacteria. Although UV disinfection is effective at inactivating most microorganisms, some microbe species may be entirely impervious. A pilot study was conducted to compare the quantity and community component of bacteria in surface water collected from filtration effluent before UV disinfection with different doses of UV, and those 1 and 2 days afterwards, in darkness. The aim was to elucidate the relationship between the UV dose and the total revived microorganisms in darkness after UV disinfection. In the filtration effluent samples, Gammaproteobacteria, Bacilli, Actinobacteria, and Alphaproteobacteria were the predominant classes. After storage in the dark at a constant temperature of 19 °C, the UV-disinfected samples showed a considerable increase in Bacilli, while Gammaproteobacteria remained the predominant population. Genera such as Exiguobacterium, Citrobacter, Acinetobacter, and Pseudomonas presented a selective advantage in terms of revival in darkness after UV disinfection, irrespective of the UV dose and storage time. The lowest rate of microbial revival (5% day-1) was noted at a UV dose of 266.10 mJ m-2 (with an average UV illumination time of 124.4 s and an average intensity of 86.61 W m-2). Our results suggest that higher UV intensity and lower illumination time are key factors in minimizing the revival of microorganisms in darkness.

Abstract
BACKGROUND Admission electrocardiographic (ECG) findings of non-ST-segment elevation myocardial infarction (NSTEMI) include transient ST-segment elevation (TSTE), ST-segment depression (STD), T-wave inversion (TWI), and no ischemic changes (NIC). HYPOTHESIS This study aimed to assess the prognostic value of qualitative ECG findings at presentation and to clarify the influence of invasive treatment on the prognostic value of admission ECG findings. METHODS We analyzed the Acute Coronary Syndrome Quality Improvement in Kerala (ACS QUIK) study post hoc. NSTEMI patients were included and classified into four groups per ECG findings. Study endpoints were in-hospital and 30-day mortality rates and major adverse events (MAE). We performed multivariate logistic regression, adjusting for covariates in the Global Registry of Acute Coronary Events risk model, with subset analyses of patients treated with or without invasive management. RESULTS STD patients had significantly higher in-hospital and 30-day mortality rates/MAE than TWI patients, which had lower in-hospital mortality rate/MAE than the NIC group. TSTE patients had intermediate outcomes. In multivariate logistic regression using the TWI group as the reference, STD and NIC remained independently associated with worse outcomes. Subset analysis showed prognostic value of admission ECG in non-invasively managed but not in invasively managed patients. CONCLUSIONS STD was associated with adverse outcomes, TWI with benign prognoses. NIC should not be taken to indicate low risk. Qualitative analysis of admission ECG is suitable for rapid risk stratification of NSTMI patients at presentation. However, it may not be predictive of short-term outcomes of NSTEMI patients after invasive management.

Abstract
BACKGROUNDS The prognosis and management of left ventricular thrombus (LVT) following acute myocardial infarction (AMI) have not been well evaluated since the advent of primary percutaneous coronary intervention (PCI). We therefore conducted a meta-analysis to assess the prognostic effect of LVT after AMI in primary PCI era and investigate the impact of triple therapy on outcomes. METHODS We searched MEDLINE, EMBASE and the Cochrane Library for studies conducted in primary PCI era up to 29 March 2019, compering the incidence of embolic events and mortality after AMI between LVT patients and Non-LVT patients. Random-effect models were used. Subgroup analysis was done by comparing triple therapy treated LVT group with Non-LVT group. RESULT A total of 12 studies were included. LVT was associated with increased risk of embolic events and long-term mortality (RR 3.97, 95%CI 2.68-5.89, P < 0.0001; RR 2.34, 95%CI 1.38-3.96, P = 0.002). Subgroup analysis was also done by comparing triple therapy treated LVT group with Non-LVT group. Despite a downward tendency was observed, the embolic risk of triple therapy subgroup was higher than non-LVT group (RR 2.79, 95%CI 1.32-5.91, P = 0.007). Triple therapy subgroup had a similar mortality rate compared with non-LVT group (RR 0.93, 95%CI 0.34-2.52, P = 0.88). CONCLUSION In primary PCI era, LVT formation after AMI indicated a fourfold increased embolic risk and twofold long-term mortality rate. Triple therapy may be a safe way to improve the outcomes, but still need to be confirmed by future trials.

Abstract
Objective: To assess the feasibility and value of real-time image fusion technique guiding the procedure of transjugular intrahepatic portosystemic shunt(TIPS). Methods: From July 2017 to May 2018,a total of 48 consecutive patients complicated by portal venous hypertension due to cirrhosis who underwent TIPS were prospectively allocated into two groups that 27 cases underwent normal TIPS and 21 cases underwent image fusion guided TIPS. There were 25 males and 23 females with a mean age of 29-74(51±10) years. The differences of portal vein(PV) between image fusion angiographyand digital subtraction angiography(DSA), and the times of puncture PV, X-ray exposure dose and exposure time and contrast agent amount of all cases were collected and analyzed. Results: The longitudinal and traverse difference of PV between image fusion angiography and DSA were 1.7-2.5(2.1±0.2) mm and 0.9-1.8(1.4±0.3) mm, respectively.The times of puncture PV, X-ray exposure time and dose, and contrast agent amount between normal TIPS group and image fusion guided TIPS group were 1-7(3.8±0.6) times vs 1-3(2.0±0.6) times, 41-63(53±8)min vs 27-42(35±5) min, 513-787(644±96) mGy vs 357-524(423±59) mGy,102-196(151±23) ml vs 87-145(105±14) ml(all P<0.05), respectively. Conclusions: There are minor differences between image fusion angiography of PV and DSA. Real-time image fusion guided TIPS is feasible and valuable to reduce intraprocedural X-ray exposure time and dose and contrast agent amount of TIPS.

Abstract
We evaluated the clinical efficacy of free internal limiting membrane (ILM) flap transplantation for the treatment of large macular hole over 500 µm in 42 consecutive patients. Quantified evaluation of the post-operative macular anatomy restoration was performed by spectral-domain optical coherence tomography in the 12mo follow-up. The results showed 41 eyes achieved successful closure (97.6%). Postoperative best corrected visual acuity, ellipsoid layer, and external limiting membrane disruption were significantly improved at all follow-up time points. The central foveal thickness was significantly higher at 1mo. We concluded that free ILM flap transplantation proves to be effective to achieve anatomical and functional improvement for the treatment of large macular hole.

Abstract
BACKGROUND AND AIMS Malignant melanoma is a fatal cancer with high metastatic characteristics. Approximately 80% of skin cancer deaths are caused by metastatic melanoma. It has been established that the metastatic ability of melanoma is regulated by an intricate gene interconnection network. Thus, the aim of this study was to identify and validate hub genes associated with metastatic melanoma and to further illustrate its potential mechanisms. METHODS The method of weighted gene coexpression network analysis (WGCNA) was applied to explore potential regulatory targets and investigate the relationship between the key module and hub genes associated with the metastasis ability of melanoma. RESULTS In the turquoise module, 26 hub genes were initially selected, and 6 of them were identified as "real" hub genes with high connectivity in the protein-protein interaction network. In terms of validation, PKP1 had the highest correlation with metastasis among all the "real" hub genes. Data obtained from the GEPIA database and the Gene Expression Omnibus database showed a lower expression of PKP1 in melanoma tissues compared to normal skin tissues. The results also showed that PKP1 was downregulated in metastatic melanomas (n = 367) compared with primary melanomas (n = 103) in The Cancer Genome Atlas (TCGA) database (n = 470). Furthermore, an ROC curve showed that PKP1 expression had good power in the diagnostics of both primary melanoma (p = 5.30e-06, AUC = 0.8) and metastatic melanoma (p = 1.13e-10, AUC = 0.925). We also found that PKP1 could distinguish low- and high-grade of metastatic melanomas and was associated with inflammatory melanoma. Moreover, in a tumor-bearing mouse model, melanoma tissues also showed lower mRNA expression of PKP1 than the adjacent normal skin. Finally, Gene Set Enrichment Analysis indicated that the calcium signaling was significantly enriched in metastatic melanoma with highly expressed PKP1. CONCLUSIONS PKP1 was identified as a new potential tumor suppressor in human melanoma, likely through regulating calcium signaling pathways.

Abstract
Throughout the world, busy waterways near large ports witness heavy vessel traffic in recent decades. The waterways are characterized by high risk in terms of loss of life, property, and pollution to environment. To facilitate maritime safety management with satisfactory efficiency and efficacy, the authors propose a framework of safety indexes to evaluate the risk level in busy waterways according to the accident severity, fatality rate and special indicators of maritime transportation. The safety indexes consist of Safety Evaluation Index (SEI) and Safety Warning Index (SWI), and are derived from the proposed risk criteria of Chinese vessel traffic. As a case study, data on vessel traffic accidents reported in the Western Shenzhen Port, South China from 1995 to 2015 are analyzed. The actual risk level of this area during the period is calculated under the framework. The implementation of the safety indexes indicate that the risk criteria and safety indexes are practicable and effective for the vessel traffic management. The methodology based on long-term accident data can significantly support the risk analysis in the macroscopic perspective for busy ports and waterways, such that SWI can act as threshold to trigger actions, while SEI can act as an indicator to measure safety status.

Abstract
OBJECTIVE To develop an independent prognostic signature for patients with hepatocellular carcinoma (HCC). METHODS HCC gene expression profile the cancer genome atlas-liver hepatocellular carcinoma and GSE14520 were used as discovery and test set, respectively. Differentially expressed genes (DEGs) were identified between HCC tissues and adjacent normal liver tissues. Univariate Cox proportional hazards regression analysis was performed to identify DEGs correlated with survival of HCC patients. A 4-gene-based signature was constructed based on a least absolute shrinkage and selection operator Cox penalized regression model. The predictive value of the signature was analyzed and validated. RESULTS Two hundred sixty-three DEGs were identified between HCC and adjacent liver tissues. After univariate survival analysis, 90 DEGs were found to be significantly correlated with the overall survival (OS) of HCC patients, of which 4 genes (KPNA2, CDC20, SPP1, and TOP2A) with non-zero coefficient were used to construct a prognostic signature. The 4-gene signature was significantly associated with the age (P = 0.046), grade ( P = 0.022), and T stage ( P = 0.023) of HCC patients in the discovery set and it also significantly associated with TNM stage ( P = 0.033), and serum alpha-fetoprotein lever ( P = 0.034). Patients in the 4-gene low-risk group were associated with better OS and recurrence-free survival (RFS) than those in the high-risk group in the discovery and test set. Meanwhile, the 4-gene signature is an independent prognostic factor regarding OS and RFS in the discovery and test set. CONCLUSION We developed a 4-gene-based signature, which could be a candidate prognostic factor for patients with HCC.

Abstract
This study observed the effects of early intravenous low-doses of metoprolol on cardiac sympathetic activities and electrophysiological properties in myocardial infarction (MI) dogs. Thirty two mongrel dogs with the first diagonal branch of the left anterior descending coronary artery ligated were randomly divided into three groups: The low-dose group was given metoprolol 0.6 mg/kg immediately by intravenous injection (n=12); the target-dose group was given metoprolol 1.6 mg/kg (n=12), and the control group was injected with normal saline at the same dose of the target-dose group (n=8). Norepinephrine (NE) and epinephrine (E) levels in the coronary sinus (CS) blood as well as the ventricular effective refractory period (ERP) were all measured during the experiments. We found that NE and E concentrations in the three groups were all increased compared with the previous measurement before ligation. ERP values after MI were significantly decreased in all three groups compared with the first measurements. The three groups all exhibited uneven shortness of ERP among different regions, with significant shortness in infarcted area. Furthermore, there was no difference between the low and target-dose of metoprolol in the reduction of regional ERP, and the same effect was also observed in induced arrhythmias. In conclusion, a lower dose of metoprolol performed similarly as target-dose in reducing the catecholamine concentrations in dogs with MI. Our study demonstrated that a lower dose of metoprolol may be reasonable compared with the target-dose in β-blocker therapy due to similar effect and lower toxicity.

Abstract
Background Colon cancer (CC) patients with early relapse usually have a poor prognosis. In this study, we aimed to identify a novel signature to improve the prediction of relapse-free survival (RFS) in CC. Methods Four microarray datasets were merged into a training set (n=1,045), and one RNA-sequencing dataset was used as a validation set (n=384). In the training set, microarray meta-analysis screened out 596 common RFS-related genes across datasets, which were used to construct 177,310 gene pairs. Then, the LASSO penalized generalized linear model identified 16 RFS-related gene pairs, and a risk score was calculated for each sample according to the model coefficients. Results The risk score demonstrated a good ability in predicting RFS (area under the curve [AUC] at 5 years: 0.724; concordance index [C-index]: 0.642, 95% CI: 0.615–0.669). High-risk patients showed a poorer prognosis than low-risk patients (HR: 3.519, 95% CI: 2.870–4.314). Subgroup analysis reached consistent results when considering multiple confounders. In the validation set, the risk score had a similar performance (AUC at 5 years: 0.697; C-index: 0.696, 95% CI: 0.627–0.766; HR: 2.926, 95% CI: 1.892–4.527). When compared with a 13-gene signature, a 15-gene signature, and TNM stage, the score showed a better performance (P<0.0001; P=0.0004; P=0.0125), especially for the patients with a longer follow-up (R2=0.988, P<0.0001). When the follow-up was >5 years (n=314), the score demonstrated an excellent performance (C-index: 0.869, 95% CI: 0.816–0.922; HR: 13.55, 95% CI: 7.409–24.78). Conclusion Our study identified a novel gene-pair signature for prediction of RFS in CC.

Abstract
Background and aims Gastric cancer (GC) is one of the most common cancers worldwide, and its pathogenesis is related to a complex network of gene interactions. The aims of our study were to find hub genes associated with the progression and prognosis of GC and illustrate the underlying mechanisms. Methods Weighted gene co-expression network analysis (WGCNA) was conducted using the microarray dataset and clinical data of GC patients from Gene Expression Omnibus (GEO) database to identify significant gene modules and hub genes associated with TNM stage in GC. Functional enrichment analysis and protein-protein interaction network analysis were performed using the significant module genes. We regarded the common hub genes in the co-expression network and protein-protein interaction (PPI) network as "real" hub genes for further analysis. Hub gene was validated in another independent dataset and The Cancer Genome Atlas (TCGA) dataset. Results In the significant purple module (R 2=0.35), a total of 12 network hub genes were identified, among which six were also hub nodes in the PPI network of the module genes. Functional annotation revealed that the genes in the purple module focused on the biological processes of system development, biological adhesion, extracellular structure organization and metabolic process. In terms of validation, CDH11 had a higher correlation with the TNM stage than other hub genes and was strongly correlated with biological adhesion based on GO functional enrichment analysis. Data obtained from the Gene Expression Profiling Interactive Analysis (GEPIA) showed that CDH11 expression had a strong positive correlation with GC stages (P<0.0001). In the testing set and Oncomine dataset, CDH11 was highly expressed in GC tissues (P<0.0001). Survival analysis indicated that samples with a high CDH11 expression showed a poor prognosis. Cox regression analysis demonstrated an independent predictor of CDH11 expression in GC prognosis (HR=1.482, 95% CI: 1.015-2.164). Furthermore, gene set enrichment analysis (GSEA) demonstrated that multiple tumor-related pathways, especially focal adhesion, were enriched in CDH11 highly expressed samples. Conclusion CDH11 was identified and validated in association with progression and prognosis in GC, probably by regulating biological adhesion and focal adhesion-related pathways.

Abstract
Highly pathogenic porcine reproductive and respiratory syndrome (HP-PRRS), which emerged in China in 2006, was characterized by high fever, high morbidity and high mortality. The causative agent of the disease was a highly pathogenic variant of porcine reproductive and respiratory syndrome virus (also called HP-PRRSV), which has a discontinuous deletion of 1 + 29 amino acids (aa) in the Nsp2 coding region, compared to classical PRRSV. In 2014, fattened pigs on a pig farm in Jiangxi Province suffered from clinical symptoms of high fever, dyspnoea and death. A PRRSV, termed JX2014T2, was isolated from samples of the dead pigs. Genomic analysis of the isolated PRRSV indicated that the genome of the virus was 14,960 bp in length and belonged to the North American genotype. In the Nsp2-coding region, there was a discontinuous deletion of 1 + 29 aa, similar to HP-PRRSV; however, an additional continuous deletion of 120 amino acids between aa 628 and 747 was found. Further analysis of the pathogenicity of PRRSV JX2014T2 was performed in piglets, and the results indicated that all infected piglets suffered from typical clinical symptoms of PRRS, such as high fever, cough, mental depression, anorexia, dyspnoea and palpebral swelling and died within 15 days postinfection (dpi). This demonstrated that the newly isolated PRRSV JX2014T2 strain containing an additional deletion of 120 aa is highly pathogenic to piglets, suggesting that a highly pathogenic variant with new genetic features is circulating in China.

Abstract
Sucrose signaling pathways were rapidly induced in response to early iron deficiency in rice plants, and the change of sucrose contents in plants was essential for the activation of iron deficiency responses. Sucrose is the main product of photosynthesis in plants, and it functions not only as an energy metabolite but also a signal molecule. However, a few studies have examined the involvement of sucrose in mediating iron deficiency responses in rice. In this study, we found that the decrease in photosynthesis and total chlorophyll concentration (SPAD values) in leaves occurred at a very early stage under iron deficiency. In addition, the sucrose was increased in leaves but decreased in roots of rice plants under iron deficiency, and also the sucrose transporter (SUT) encoded genes' expression levels in leaves were all inhibited, including OsSUT1, OsSUT2, OsSUT3, OsSUT4, and OsSUT5. The carbohydrate distribution was changed under iron deficiency and sucrose might be involved in the iron deficiency responses of rice plants. Furthermore, exogenous application of sucrose or dark treatment experiments were used to test the hypothesis; we found that the increased endogenous sucrose would cause the repression of iron acquisition-related genes in roots, while further stimulated iron transport-related genes in leaves. Compared to the exogenous application of sucrose, the dark treatment had the opposite effects. All the above results highlighted the important role of sucrose in regulating the responses of rice plants to iron deficiency.

Abstract
White-light flares are the flares with emissions visible in the optical continuum. They are thought to be rare and pose the most stringent requirements in energy transport and heating in the lower atmosphere. Here we present a nearly circular white-light flare on 10 March 2015 that was well observed by the Optical and Near-infrared Solar Eruption Tracer and Solar Dynamics Observatory. In this flare, there appear simultaneously both impulsive and gradual white-light kernels. The generally accepted thick-target model would be responsible for the impulsive kernels but not sufficient to interpret the gradual kernels. Some other mechanisms including soft X-ray backwarming or downward-propagating Alfvén waves, acting jointly with electron beam bombardment, provide a possible interpretation. However, the origin of this kind of white-light kernel is still an open question that induces more observations and researches in the future to decipher it.

Abstract
The present study aimed to identify differentially expressed genes (DEGs) in colorectal cancer (CRC) and provide novel prognostic biomarkers for CRC. The microarray dataset GSE41258 was used to screen DEGs of CRC. Subsequently, a protein-protein interaction network of DEGs and Gene Ontology analysis were performed to identify hub genes and associated biological processes. Nebulette (NEBL) and complement C1q like 1 (C1QL1) were validated using reverse transcription-quantitative polymerase chain reaction in patients with CRC. Survival analysis was performed for the two hub genes. GSE41258 dataset included 182 CRC samples and 54 normal tissues. A total of 759 DEGs, including 279 upregulated and 480 downregulated were screened between both groups. NEBL and C1QL1 were identified as the two hub genes and upregulated genes involved in various biological processes, including ‘regulation of biological quality’ and ‘response to stimulus’, respectively. Additionally, the overexpression of NEBL and C1QL1 in experimental validation was consistent with the aforementioned bioinformatics analysis results. Survival analysis suggested that overexpressed NEBL in patients with CRC was associated with a positive prognosis for overall survival. In conclusion, CRC was associated with a large group of DEGs. From the upregulated genes, overexpressed NEBL in patients CRC indicated a positive prognosis for overall survival and may be used as a prognostic biomarker for patients with CRC.

Abstract
The aim of this study is to investigate the diagnostic efficacy of neutrophil-to-lymphocyte ratio (NLR), neutrophil-to-monocyte ratio (NMR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR) in patients with Crohn's disease (CD) and non-CD controls. These ratios were all derived from complete blood counts. Two hundred and six participants including CD inpatients and non-CD controls were retrospectively enrolled. We found statistically higher NLR and PLR and lower LMR in CD patients than in non-CD controls (all P < 0.01). However, NMR was not different between the two groups (P = 0.18). In addition, NLR, PLR, and LMR were associated with CRP and ESR. Optimal cutoffs for NLR and PLR were 2.72 (sensitivity: 68.3%, specificity: 75.9%, and overall accuracy: 70.1%) and 132.88 (sensitivity: 76.7%, specificity: 84.8%, and overall accuracy: 80.8%), respectively. In conclusion, the NLR and PLR might be effective, readily available, and low-cost biomarkers for differentiating CD patients from non-CD controls.

Abstract
AIM The aim of this study was to identify the best probiotic supplementation in triple therapy for pediatric population with Helicobacter pylori infection. METHODS Eligible trials were identified by comprehensive searches. Relative risks with 95% confidence intervals and relative ranks with P scores were assessed. RESULTS Twenty-nine trials (3122 participants) involving 17 probiotic regimens were identified. Compared with placebo, probiotic-supplemented triple therapy significantly increased H. pylori eradication rates (relative ratio (RR) 1.19, 95% CI 1.13-1.25) and reduced the incidence of total side effects (RR 0.49, 95% CI 0.38-0.65). Furthermore, to supplemented triple therapy, Lactobacillus casei was identified the best for H. pylori eradication rates (P score = 0.84), and multi-strain of Lactobacillus acidophilus and Lactobacillus rhamnosus for total side effects (P score = 0.93). As for the subtypes of side effects, multi-strain of Bifidobacterium infantis, Bifidobacterium longum, L. acidophilus, L. casei, Lactobacillus plantarum, Lactobacillus reuteri, L. rhamnosus, Lactobacillus salivarius, Lactobacillus sporogenes, and Streptococcus thermophilus was the best to reduce the incidence of diarrhea; multi-strain of Bacillus mesentericus, Clostridium butyricum, and Streptococcus faecalis for loss of appetite; multi-strain of B. longum, Lactobacillus bulgaricus, and S. thermophilus for constipation; multi-strain of Bifidobacterium bifidum, B. infantis, L. acidophilus, L. bulgaricus, L. casei, L. reuteri, and Streptococcus for taste disturbance; Saccharomyces boulardii for bloating; and multi-strain of Bifidobacterium breve, B. infantis, L. acidophilus, L. bulgaricus, L. casei, L. rhamnosus, and S. thermophilus for nausea/vomiting. CONCLUSIONS Probiotics are recommended to supplement triple therapy in pediatrics, and the effectiveness of triple therapy is associated with specific probiotic supplementation.

Abstract
OBJECTIVE To investigate the prevalence of key unlawful acts among electric bicycle riders and provide evidence for the development of specific interventions. METHODS A 4-day road-side survey was conducted in Jinhua, Zhejiang province, in 2013. The speed of electric bicycle was measured by speed measuring instrument and the unlawful acts of riders, such as reverse riding, running the red-light and carrying passengers, were observed with non-participatory way. RESULTS A total of 3 448 running electric bicycles were observed and the average speed was 26 km/h, the proportion of electric bicycle at the speed of ≥15 km/h was 87.06%. The average speed was highest during 10 am-11 am(30 km/h). the number of observed electric bicycle riders with unlawful acts of ' running the red-light','reverse riding' and ' carrying passengers' were 1 315, 656 and 1 877 respectively, and the estimated rate was 10.01%, 4.99% and 15.22%, respectively. More ' running the red-light','reverse riding' and ' carrying passengers' occurred during 7 am-8 am(14.59%)and 13 pm-14 pm(15.25%), 13 pm-14 pm(7.33%)and 17 pm-18 pm(7.63%), 6 am-7 am(32.44%)and 12 pm-13 pm(27.90%), respectively. CONCLUSION Overspeeding, carrying passengers, running the red-light, reverse riding were the key unlawful acts among electric bicycle riders. Targeted intervention should be carried out to reduce the prevalence of unlawful riding acts and the incidence of electric bicycle related injuries and deaths.

Abstract
Selective adsorption by use of metal-organic frameworks (MOFs) is an effective method for purification of hydrocarbon fuels. In consideration that the adsorption processes proceed in liquid phases, separation and recycling of adsorbents should be greatly facilitated if MOFs were endowed with magnetism. In the present study, we reported for the first time a dry gel conversion (DGC) strategy to fabricate magnetically responsive MOFs as adsorbents for deep desulfurization and denitrogenation. The solvent is separated from the solid materials in the DGC strategy, and vapor is generated at elevated temperatures to induce the growth of MOFs around magnetic Fe3O4 nanoparticles. This strategy can greatly simplify the complicated procedures of the well-known layer-by-layer method and avoid the blockage of pores confronted by introducing magnetic Fe3O4 nanoparticles to the pores of MOFs. Our results show that the adsorbents are capable of efficiently removing aromatic sulfur and nitrogen compounds from model fuels, for example removing 0.62mmolg-1S and 0.89mmolg-1N of thiophene and indole, respectively. In addition, the adsorbents are facile to separate from liquid phases by use of an external field. After 6 cycles, the adsorbents still show a good adsorption capacity that is comparable to the fresh one.

Abstract
Background The rich neovascularization of renal angiomyolipoma (AML) has a tendency for spontaneous rupture with subsequent hemorrhage. Nephrectomy or nephron-sparing surgery has rarely been used as a primary treatment in urgent situations. Purpose To evaluate the safety and long-term outcomes for patients treated by urgent transcatheter arterial embolization (TAE) for spontaneous ruptured renal AML with severe hemorrhage. Material and Methods A retrospective evaluation was performed of 25 renal AML cases with spontaneous hemorrhage confirmed by imaging. Polyvinyl alcohol (PVA) particles and coils of multiple sizes were used to embolize the spontaneous renal AML ruptures. Results The technical success rate of TAE was 96% (24/25). One week post-TAE, 1 patient with recurrent hemorrhage underwent emergency nephrectomy. Minor complications affected 16 patients with post-embolization syndrome; 15 patients resolved using conservative measures and one patient received nephrectomy post TAE 1 week later. All patients were followed up for 24-72 months (median, 50.2 months). Surgical treatment was avoided for 92% (23/25) of patients, and the re-embolization rate was 0% at 2 years post TAE. In the 23 patients without surgical treatment, the mean maximum diameter of renal AML was reduced from 12.4 ± 5.5 cm to 6.3 ± 2.5 cm and no hemorrhage occurred during follow-up. Conclusion Urgent TAE is a technically feasible and minimally invasive procedure for controlling severe hemorrhage and preservation of renal function following spontaneous ruptured renal AML.

Abstract
Abstract
A new rare-earth borate K3TbB6O12 has been prepared using the high temperature molten salt method and was structurally determined by single crystal X-ray diffraction analyses. The structure features a three-dimensional (3D) framework which is composed of isolated B5O10, KO6, KO8 and TbO6 groups. An atom site in the 32 screw axis is shared by K and Tb atoms with the molar ratio of 1:1. The self-activated photoluminescence (PL) property of K3TbB6O12 was studied. Under the excitation of 378 nm, the emission spectrum exhibits an intense green emission centered at 543–548 nm with the chromaticity coordinates (0.342, 0.590), which can be assigned to the 5D4→7F5 transition of Tb3+. The excitation spectra cover a wide range from 330 to 385 nm, which suggests that the K3TbB6O12 phosphors can be effectively excited by a near-UV light source. One may expect that compound K3TbB6O12 can be used as a green phosphor pumped by near-UV LED chips.

Abstract
AIM: To evaluate the clinical efficacy of agitation thrombolysis via transjugular access for the treatment of acute portal vein thrombosis.
METHODS: Thirteen patients with acute portal vein thrombosis treated from October 2012 to March 2015 at our hospital were analyzed retrospectively. The portal vein was approached via the transjugular intrahepatic portosystemic route, followed by agitation thrombolysis to resolve the thrombi. The need for transjugular intrahepatic portosystemic shunt (TIPS) was based on the presence of portal hypertension, and then a catheter was indwelled into the thrombi. The success rate, thrombolytic therapeutic time and effect, and complications were observed. Computed tomography and Doppler ultrasound were performed to follow the patency of the portal vein and TIPS stent.
RESULTS: Agitation thrombolysis were successfully created in 12 patients. Of 8 patients who underwent TIPS, 1 underwent wide resection due to confirmed extensive intestinal necrosis on postoperative day 2; however, the patient died 9 d later. In the remaining 11 patients, the portal vein was recanalized > 90% as revealed by CT findings. There was a significant difference in lumen occupancy between pre- and post-operation (P < 0.01). The clinical symptoms such as abdominal pain, ascites, and gastrointestinal bleeding were all relieved or disappeared. The complications were mainly as follows: intraoperative subcapsular bleeding in one patient; death due to intestinal necrosis in one patient; hepatic encephalopathy at 3 mo in one patient with TIPS; and hematuria during thrombolysis in one patient. During follow-up, TIPS stent stenosis was noted in one patient at 7 mo and treated by balloon angioplasty.
CONCLUSION: Agitation thrombolysis via transjugular access for the treatment of acute portal vein thrombosis is safe and effective.

Abstract
Purpose To evaluate the effect of transcatheter arterial embolization (TAE) combined with radiofrequency ablation (RFA) treatment (TAE + RFA) on the expression of heat shock protein 70 (HSP70) in residual tumors and explore the relationship between the HSP70 and CD8+ T-cell infiltrate surrounding residual tumors in the rabbit VX2 liver tumor model. Materials and methods Animals with VX2 liver tumors were randomized into four groups (control, TAE, RFA, and TAE + RFA) with 15 rabbits in each group. Five rabbits in each group were sacrificed on days 1, 3, and 7 after treatment. HSP70 expression and infiltration of CD8+ T-cells in the liver and residual tumors surrounding the necrosis zone were detected by immunohistochemistry staining. The maximal diameters of tumor necrosis, numbers of metastases, and tumor growth rate were compared on day 7 after treatment. Results TAE + RFA achieved larger maximal diameter of tumor necrosis, lower tumor growth rate, and fewer metastatic lesions, compared with other treatments on day 7. The number of CD8+ T-cells in the TAE + RFA group was significantly higher than in other groups on days 1, 3, and 7. There was a positive correlation between HSP70 expression level and infiltration of CD8+ T-cells surrounding the residual tumor on day 1 (r=0.9782, P=0.012), day 3 (r=0.93, P=0.021), and day 7 (r=0.8934, P=0.034). Conclusion In the rabbit VX2 liver tumor model, TAE + RFA activated the highest number of CD8+ T-cells surrounding residual tumors. TAE + RFA appears to be a beneficial therapeutic modality for tumor control and antitumor immune response in this model.

Abstract
AIM: To determine the clinical features and endovascular treatment of visceral artery pseudoaneurysms (VAPA).
METHODS: Clinical data and our experience with interventional treatment of 42 patients with VAPA were retrospectively analyzed. Follow-up was carried out via assessment of contrast-enhanced computed tomography or computed tomography angiography images.
RESULTS: Endovascular treatment was technically successful in 38 (90.4%) patients, of whom one died of multisystem organ failure 28 d after intervention. The 30 d mortality rate was 2.4% (1/42). Four patients required secondary interventions because of rebleeding and were successfully treated by reintervention. In the follow-up period, 17 patients suffering from cancer died from 1 to 12 mo after embolization because of disease progression (n = 8), multisystem organ failure (n = 7), myocardial infarction (n = 1), and septic shock (n = 1). Four patients suffered partial splenic infarction and post-embolization syndrome. During follow-up, no patient had hepatic insufficiency or bowel ischemia; no VAPA occurred in all patients.
CONCLUSION: Endovascular management is minimally invasive and highly successful in treating VAPA and particularly useful in poor surgical candidates.

Abstract
Objectives To determine the safety and feasibility of intraductal radiofrequency ablation (RFA) followed by locoregional tumor treatments in patients with non-resectable malignant biliary obstruction and stent re-occlusion. Methods Fourteen patients with malignant biliary obstruction and blocked metal stents were studied retrospectively. All had intraductal RFA followed by locoregional tumor treatments and were monitored clinically and radiologically. The practicality, safety, postoperative complications, jaundice remission, stent patency and survival time were analyzed. Results Combination treatment was successful for all patients. There were no severe complications during RFA or local treatments. All patients had stent patency restored, with a decline in serum bilirubin. Three patients had recurrent jaundice by 195, 237 and 357 days; two patients underwent repeat intraductal RFA; and one required an internal-external biliary drain. The average stent patency time was 234 days (range 187-544 days). With a median follow-up of 384 days (range 187-544 days), six patients were alive, while eight had died. There was no mortality at 30 days. The 3, 6, 12 and 18 month survival rates were 100%, 100%, 64.3% and 42.9%, respectively. Conclusion Intraductal RFA followed by locoregional tumor treatments for occluded metal stents is safe and practically feasible and potential increase stent patency and survival times.

Abstract
Magnetic reconnection, a change of magnetic field connectivity, is a fundamental physical process in which magnetic energy is released explosively, and it is responsible for various eruptive phenomena in the universe. However, this process is difficult to observe directly. Here, the magnetic topology associated with a solar reconnection event is studied in three dimensions using the combined perspectives of two spacecraft. The sequence of extreme ultraviolet images clearly shows that two groups of oppositely directed and non-coplanar magnetic loops gradually approach each other, forming a separator or quasi-separator and then reconnecting. The plasma near the reconnection site is subsequently heated from ∼1 to ≥5 MK. Shortly afterwards, warm flare loops (∼3 MK) appear underneath the hot plasma. Other observational signatures of reconnection, including plasma inflows and downflows, are unambiguously revealed and quantitatively measured. These observations provide direct evidence of magnetic reconnection in a three-dimensional configuration and reveal its origin. Magnetic reconnection is a fundamental energy release process taking place in various astrophysical environments, but it is difficult to observe it directly. Here, the authors provide evidence of three-dimensional magnetic reconnection in a solar eruption using combined perspectives of two spacecraft.

Abstract
AIM: To determine the value of computed tomographic angiography (CTA) for diagnosis and therapeutic planning in lower gastrointestinal (GI) bleeding.
METHODS: Sixty-three consecutive patients with acute lower GI bleeding underwent CTA before endovascular or surgical treatment. CTA was used to determine whether the lower GI bleeding was suitable for endovascular treatment, surgical resection, or conservative treatment in each patient. Treatment planning with CTA was compared with actual treatment decisions or endovascular or surgical treatment that had been carried out in each patient based on CTA findings.
RESULTS: 64-row CTA detected active extravasation of contrast material in 57 patients and six patients had no demonstrable active bleeding, resulting in an accuracy of 90.5% in the detection of acute GI bleeding (57 of 63). In three of the six patients with no demonstrable active bleeding, active lower GI bleeding recurred within one week after CTA, and angiography revealed acute bleeding. The overall location-based accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for the detection of GI bleeding by 64-row CTA were 98.8% (249 of 252), 95.0% (57 of 60), 100% (192 of 192), 100% (57 of 57), and 98.5% (192 of 195), respectively. Treatment planning was correctly established on the basis of 64-row CTA with an accuracy, sensitivity, specificity, PPV and NPV of 98.4% (248 of 252), 93.3% (56 of 60), 100% (192 of 192), 100% (56 of 56), and 97.5% (192 of 196), respectively, in a location-based evaluation.
CONCLUSION: 64-row CTA is safe and effective in making decisions regarding treatment, without performing digital subtraction angiography or surgery, in the majority of patients with lower GI bleeding.

Abstract
Spectrum peak detection in the laser-induced breakdown spectroscopy (LIBS) is an essential step, but the presence of background and noise seriously disturb the accuracy of peak position. The present paper proposed a method applied to automatic peak detection for LIBS spectrum in order to enhance the ability of overlapping peaks searching and adaptivity. We introduced the ridge peak detection method based on continuous wavelet transform to LIBS, and discussed the choice of the mother wavelet and optimized the scale factor and the shift factor. This method also improved the ridge peak detection method with a correcting ridge method. The experimental results show that compared with other peak detection methods (the direct comparison method, derivative method and ridge peak search method), our method had a significant advantage on the ability to distinguish overlapping peaks and the precision of peak detection, and could be be applied to data processing in LIBS.
