Abstract
A good integration of dental implants and the surrounding soft tissue is essential to ensure the long-term effect of implant. In this review, we summarized the research progress of peri-implant soft tissue integration of dental titanium implants, with emphasis on the modification of the gingival interface of implants based on immune microenvironment regulation. This method influences the immune response around the implant by promoting the surface properties of implants, so as to enhance the peri-implant soft tissue integration. The purpose of this review is to provide reference for the related research and clinical application in the field of dental implantation.

Abstract
Sixteen patients with recurrent high-grade glioma who were treated by domestic magnetic resonance-guided laser interstitial thermotherapy (MRgLITT) in the Neurosurgery Department of Xuanwu Hospital of Capital Medical University from 1st January 2021 to 31st December 2021 were prospectively included, with 11 males and 5 females, and aged 27-74 (50±16) years. The duration of surgery, the rate of ablation after surgery, and perioperative complications were assessed. The patients were followed up every 3 months to assess survival and progression. A total of 5 WHO grade Ⅲ patients and 11 WHO grade Ⅳ patients were included. The operation time was 144 (109, 176) min, 28 targeted lesions were detected, and the ablation rate [M (Q1, Q3)] was 91.0% (87.4%, 93.3%). After surgery, 2 patients (2/16) had decreased limb muscle strength, and no perioperative death or other serious complications occurred. The median time to a complete response was 12 (5, 14) months in WHO Grade Ⅲ patients, and one died 12 months after surgery, while the median time to a complete response was 3 (1, 8) months in 11 WHO Grade Ⅳ patients, with a total of 8 deaths at the last follow-up. Therefore, domestic MRgLITT has certain efficacy and safety in the treatment of recurrent high-grade glioma, providing a new option for patients with recurrent glioma.

Abstract
Severe acute dichlorvos poisoning is characterized by rapid onset, swift disease progression and serious complications. It frequently involves multiple organ failure (central, respiratory and circulatory systems), severe acidosis, and rare occurrences of gastric perforation. When secondary gastric perforation occurs, treatment becomes difficult and the prognosis of patients is poor. Thus, early and sufficient gastrointestinal decontamination is crucial. This article presented two cases of gastric perforation secondary to dichlorvos poisoning and discussed the causes of gastric perforation, as well is clinical diagnostic and treatment methods.

Abstract
BACKGROUND Though the CXCR2 chemokine receptor is known to play a key role in cancer growth and response to therapy, a direct link between expression of CXCR2 in tumor progenitor cells during induction of tumorigenesis has not been established. METHODS To characterize the role of CXCR2 during melanoma tumorigenesis, we generated tamoxifen-inducible tyrosinase-promoter driven BrafV600E/Pten-/-/Cxcr2-/- and NRasQ61R/INK4a-/-/Cxcr2-/- melanoma models. In addition, the effects of a CXCR1/CXCR2 antagonist, SX-682, on melanoma tumorigenesis were evaluated in BrafV600E/Pten-/- and NRasQ61R/INK4a-/- mice and in melanoma cell lines. Potential mechanisms by which Cxcr2 affects melanoma tumorigenesis in these murine models were explored using RNAseq, mMCP-counter, ChIPseq, and qRT-PCR; flow cytometry, and reverse phosphoprotein analysis (RPPA). RESULTS Genetic loss of Cxcr2 or pharmacological inhibition of CXCR1/CXCR2 during melanoma tumor induction resulted in key changes in gene expression that reduced tumor incidence/growth and increased anti-tumor immunity. Interestingly, after Cxcr2 ablation, Tfcp2l1, a key tumor suppressive transcription factor, was the only gene significantly induced with a log2 fold-change greater than 2 in these three different melanoma models. CONCLUSIONS Here, we provide novel mechanistic insight revealing how loss of Cxcr2 expression/activity in melanoma tumor progenitor cells results in reduced tumor burden and creation of an anti-tumor immune microenvironment. This mechanism entails an increase in expression of the tumor suppressive transcription factor, Tfcp2l1, along with alteration in the expression of genes involved in growth regulation, tumor suppression, stemness, differentiation, and immune modulation. These gene expression changes are coincident with reduction in the activation of key growth regulatory pathways, including AKT and mTOR.

Abstract
Objective: To examine the outcomes of Tiantan first-aid protocol on critically ill patients with primary central nervous system lymphoma (PCNSL). Methods: The clinical data of 18 patients with PCNSL who were treated according to Tiantan first-aid protocol at Department of Neurosurgery,Beijing Tiantan Hospital, Capital Medical University from November 2019 to December 2021 were retrospectively analyzed. There were 9 males and 9 females, aged (56.9±11.1)years (range: 29 to 77 years). The median Karnofsky performance status(KPS) score at admission was 40 (range: 20 to 60). Three patients were mild coma, 3 were lethargy and 12 were conscious. The mean midline shift was 0.7 cm (range: 0 to 1.8 cm). After admission, all patients were treated according to the plan of rapid biopsy, rapid routine pathology and rapid salvage chemotherapy. The treatment procedures, clinical and radiographic outcomes, KPS score and adverse reactions of patients after chemotherapy were collected. Results: All of the 18 patients completed the first-aid treatment. The median duration from admission to the biopsy was 1 day (range: 0 to 5 days), from biopsy to routine pathological diagnosis was 1 day (range: 1 to 4 days) and from routine pathology to salvage chemotherapy was 1 day (range: 0 to 4 days). All the patients were pathologically confirmed with diffuse large B cell lymphoma, 1 patient was double-hit lymphoma. Seventeen patients underwent clinical remission and 1 died of cardiac dysfunction. The successful salvage rate was 17/18. Radiologically, complete remission was observed in 1 case, partial remission in 16 cases, and stable disease in 1 case. The median KPS score at discharge was 60 (range: 30 to 80). The mild gastrointestinal, hematological and hepatic adverse effects were observed after chemotherapy. Conclusion: Tiantan first-aid protocol is effective for critically ill patients with PCNSL, which has the merit to be popularly used and improved.

Abstract
Chlorfenapyr is a moderately dangerous insecticide widely used in agriculture. The mortality of acute poisoning patients is high, and there is no effective treatment. This paper retrospectively analyzes the clinical data of two cases of compound chlorfenapyr poisoning. The main symptoms of the patients were high fever, sweating, gradual coma, increased creatine kinase and myoglobin, with delayed poisoning symptoms. Despite comprehensive treatment, both patients died eventually. It indicated that chlorfenapyr was highly toxic and had a high mortality. In addition to routine symptomatic treatment for patients with acute poisoning, blood purification treatment should be actively carried out in the early stage.

Abstract
Understanding the barriers and tackling the hurdles of hepatitis C virus (HCV) care cascades is key to HCV elimination. The current study aimed to investigate the rates of disease awareness, link-to-care, and treatment uptake of HCV in a hyperendemic area in Taiwan. Tzukuan residents from 2000 to 2018 were invited to participate in the questionnaire-based interviews for HCV. The rates of disease awareness, accessibility, and anti-HCV therapy were evaluated in anti-HCV-seropositive participants. Among 10,348 residents, 1789 (17.3%) were anti-HCV seropositive. Of these 1789 anti-HCV-seropositive participants, data of 594 participants from questionnaire-based interviews in 2005-2018 were analyzed for HCV care cascades. Overall, 24.9% of anti-HCV-seropositive HCV participants had disease awareness, 53.9% of aware participants had accessibility, and 79.8% of assessed participants had received HCV treatment, with a community effectiveness of 10.7%. HCV prevalence decreased over time, from 21.2% in the early cohort to 9.3% in the recent cohort. Disease awareness increased over time, from 15.6% to 41.7%, with the community effectiveness increasing from 1.3% to 28.8%. Lower education levels and normal liver biochemistry were associated with a lower rate of disease awareness. Notably, 68% of participants with abnormal liver biochemistry and 69% of those with advanced fibrosis (FIB-4 > 3.25) were unaware of their HCV disease. We demonstrated huge gaps in disease awareness, link-to-care, and treatment uptake in the HCV care cascade in an HCV-hyperendemic area, even in the initial era of direct-acting antiviral agents. There is an urgent need to overcome these hurdles to achieve HCV elimination.

Abstract
The effectiveness of different treatment processes on assimilable organic carbon (AOC) removal and bacterial diversity variations was evaluated in a water treatment plant. The van der Kooij technique was applied for AOC analysis and responses of bacterial communities were characterized by the metagenomics assay. Results show that the AOC concentrations were about 93, 148, 43, 51, 37, and 38 μg acetate-C/L in effluents of raw water basin, preozonation, rapid sand filtration (RSF), ozonation, biofiltration [biological activated carbon (BAC) filtration], and chlorination (clear water), respectively. Increased AOC concentrations were observed after preozonation, ozonation, and chlorination units due to the production of biodegradable organic matters after the oxidation processes. Results indicate that the oxidation processes were the main causes of AOC formation, which resulted in significant increases in AOC concentrations (18-59% increment). The AOC removal efficiencies were 47, 28, and 60% in the RSF, biofiltration, and the whole system, respectively. RSF and biofiltration were responsible for the AOC treatment and both processes played key roles in AOC removal. Thus, both RSF and biofiltration processes would contribute to AOC treatment after oxidation. Sediments from the raw water basin and filter samples from RSF and BAC units were collected and analyzed for bacterial communities. Results from scanning electron microscope analysis indicate that bacterial colonization was observed in filter materials. This indicates that the surfaces of the filter materials were beneficial to bacterial growth and AOC removal via the adsorption and biodegradation mechanisms. Next generation sequencing analyses demonstrate that water treatment processes resulted in the changes of bacterial diversity and community profiles in filters of RSF and BAC. According to the findings of bacterial composition and interactions, the dominant bacterial phyla were Proteobacteria (41% in RSF and 56% in BAC) followed by Planctomycetes and Acidobacteria in RSF and BAC systems, which might affect the AOC biodegradation efficiency. Results would be useful in developing AOC treatment and management processes in water treatment plants.

Abstract
Objective: To investigate the safety and short-term efficacy of domestic magnetic resonance-guided laser interstitial thermotherapy (MRgLITT) in the treatment of drug-resistant epilepsy. Methods: Patients with drug-resistant epilepsy treated with a domestic MRgLITT system in the Department of Neurosurgery, Xuanwu Hospital, Capital Medical University from October 2020 to April 2021 were prospectively enrolled. The damage volume ratio was assessed immediately after surgery, and perioperative complications were recorded and followed up. The clinical safety and short-term efficacy were evaluated using the Engel classification. Results: A total of 22 patients were included, including 12 males and 10 females, aged from 3 to 45 years old [(24±13) years]. There were 5 cases of medial temporal lobe epilepsy (MTLE), 3 cases of hypothalamic hamartoma (HH), 7 cases of focal cortical dysplasia (FCD), and 7 cases of other types, respectively. The mean operation time and blood loss was (173±49) min and (3.7±1.6) ml. The postoperative length of hospital stay was (5.5±1.8) days, and the average damage volume ratio was 92.6%. Among them, only 2 patients (FCD of the parietal lobe) showed transient contralateral limb weakness, without any serious complications such as symptomatic intracranial hemorrhage and cerebral infarction. The follow-up time was 14 to 168 days. There were 13 Engel class Ⅰ cases (59.1%), 2 Engel class Ⅱ cases (9.1%), 2 Engel class Ⅲ cases (9.1%) and 5 Engel class Ⅳ cases (22.7%), respectively. Short-term incident-free rates were MTLE 5/5and FCD4/7, respectively. Conclusion: Domestic MRgLITT system is stable, reliable and safe in the treatment of drug-refractory epilepsy, and has better short-term efficacy in MTLE and FCD patients.

Abstract
BACKGROUND Currently there is limited information to guide health professionals regarding the optimal time frame to initiate safe and effective oral feedings to preterm infants. The study aims to revise and validate a streamlined version of the Traditional Chinese-Preterm Oral Feeding Readiness Assessment Scale, the TC-POFRAS®, and evaluate its construct validity in the clinical decisions regarding feeding readiness of preterm infants. METHODS Eighty-one clinically stable preterm infants were assessed using the TC-POFRAS for oral feeding readiness. Item-total correlation analysis was used to check if any item was inconsistent with the averaged TC-POFRAS scores. Cronbach's α coefficient was used to evaluate the inter-item consistency. Exploratory factor analysis was used to determine the coherence of variables to reorganize assessment domains. The revised version of TC-POFRAS (TC-POFRAS®) was developed and a new cut-off score based on discriminant accuracy was established. RESULTS Based on the results from statistical analysis, five items ("lips posture," "tongue posture," "biting reflex," "gag reflex," and "tongue cupping") were deleted from the original TC-POFRAS to form the TC-POFRAS®. The TC-POFRAS®'s global accuracy was 92.1%. The cut-off value of 19 was the one that presented the most optimization of sensitivity based on specificity. The TC-POFRAS® was reconstructed into corrected gestational age and five behavioral domains. CONCLUSIONS The TC-POFRAS® is considered a valid, safe, and accurate objective instrument to assist health professionals to initiate oral feeding of preterm infants.

Abstract
BACKGROUND The efficacy and safety of insulin sensitizer in Asians with non-alcoholic steatohepatitis (NASH) remain elusive. AIMS The double-blind, randomized, placebo-controlled trial was conducted aiming to investigate the efficacy and safety of pioglitazone in NASH patients. METHODS A total of 90 NASH patients (66 males, age = 44.1 ± 12.7 years) were prospectively randomized into oral pioglitazone 30 mg/day (Arm A) or placebo (Arm B) for 24 weeks. The primary endpoint was the efficacy of pioglitazone in reducing inflammation and liver fat at end-of-treatment (EOT). NASH resolution/improvement without fibrosis worsening was also evaluated. RESULTS At EOT, there was a significantly decline of alanine aminotransferase (86.9 ± 34.3 to 45.7 ± 35.8 IU/L, p = 0.003) level in Arm A patients. In intention-to-treat analysis among 66 patients who completed paired biopsies, The NAFLD activity score (NAS) of 30 Arm A patients significantly decreased from 4.27 ± 1.14 at baseline to 2.53 ± 1.63 at EOT (p < 0.0001), whereas there was no significant change in patients of Arm B (3.94 ± 1.41 vs 3.94 ± 1.51, p = 1.0). NASH improvement without worsening of fibrosis was achieved in 46.7% (14/30) patients in Arm A, compared to 11.1% (4/36) patients in Arm B (p = 0.002). Liver fat content reduced (20.2 ± 9.0 to 14.3 ± 6.9%, p < 0.0001) on MRI-PDFF in Arm A compared to their counterparts. No significant difference of adverse events occurred between groups. CONCLUSIONS A 24-week pioglitazone treatment was well-tolerated and effective in improving liver histology and reducing liver steatosis in Asian NASH patients.

Abstract
BACKGROUND The ItchyQoL is an itch-specific patient-reported outcome measure used to assess quality of life in patients with chronic pruritus (CP). OBJECTIVES We aimed to assess and extend the psychometric properties of the ItchyQoL using classical test theory (CTT) and item response theory (IRT). METHODS Item characteristic curves were analysed to investigate whether the response categories were functioning optimally. Confirmatory factor analyses were carried out on the ItchyQoL prior to and after rescoring of the response categories. We conducted a Rasch analysis for the ItchyQoL with revised response options and assessed the mean fit residuals in addition to the assumptions of unidimensionality and local independence. RESULTS In total, 551 patients with CP from nine European countries completed the 22 items of the ItchyQoL. IRT analysis supported the revision of response options from five points to three. This revision was supported by excellent structural validity using CTT. The overall fit to the Rasch model was adequate. Unidimensionality was supported by the ItchyQoL overall scale and by the single subscales; however, local independence was violated in eight cases. CONCLUSIONS We suggest a revision of the response categories of the ItchyQoL from a 5-point to a 3-point scale. When this revision was applied, the ItchyQoL showed excellent structural validity according to CTT and IRT/Rasch. The calculation of an overall ItchyQoL sum score is allowed.

Abstract
OBJECTIVES Hepatitis C virus (HCV) infection is the leading cause of cirrhosis and hepatocellular carcinoma worldwide. Tzukuan, located in the southwestern area of Taiwan, is an HCV hyperendemic area (>30%). This study aimed to assess the changing epidemiological characteristics of HCV infection and to evaluate the long-term outcomes after the implementation of public health strategies for two decades. DESIGN A population-based retrospective cohort study. SETTING A comprehensive care programme was implemented, namely COMPACT Study, in Tzukuan since 1997. PARTICIPANTS A total of 10 714 residents participated the screening. OUTCOME MEASURES The HCV status, demographic and clinical profiles of the participants were recorded and validated annually from 2000 through 2019. RESULTS The HCV infection prevalence rates were 21.1% (1076/5099) in 2000-2004, 18.8% (239/1269) in 2005-2009, 14.1% (292/2071) in 2010-2014 and 10.3% (234/2275) in 2015-2019 (p for trend test <0.0001). Among them, 1614 underwent repeated tests during the follow-up period. The annual incidence rates were 0.54% in 2005-2009, 0.4% in 2010-2014 and 0.22% in 2015-2019, respectively (p=0.01). In addition to old age, lower education level was a major risk factor for HCV infection across different periods. HCV infection prevalence rate among those illiterates reached 40.9%, followed by 28.5% in those with elementary school level, and <10% in those with high school or higher levels. The major risk factor has shifted from iatrogenic exposure in 2000-2009 to household transmission after 2010. CONCLUSIONS HCV infection has been decreasing and the epidemiological features are changing in the hyperendemic area by continuing education, prevention and treatment strategies.

Abstract
Background and aims Hepatitis C virus (HCV) genotyping is a pivotal tool for epidemiological investigation, guiding management and antiviral treatment. Challenge existed in identifying subtypes of genotype-1 (G-1) and genotype (GT) of indeterminate. Recently, the Abbott HCV RealTime Genotype Plus RUO assay (HCV GT Plus) has been developed aiming to overcome the limitations. We aimed to evaluate the performance of the assay compared with 5’ UTR sequencing in clinical samples. Materials and methods Eligible individuals were treatment chronic hepatitis C patients that were enrolled consecutively in a medical center and two core regional hospitals in southern Taiwan from Oct 2017 through Aug 2018. The patient with genotype 1 without subtype and indeterminate previously genotyped by Abbott RealTime HCV GT II will further determinate by Abbott HCV RealTime HCV GT Plus. All of the genotype results were validated by 5' UTR sequencing as a reference standard. Results A total of 100 viremic CHC patients were recruited, including 63 G-1 patients (male: 28), and 37 patients (male: 15) of indeterminate genotyped by Abbott RealTime HCV GT II assay (HCV GT II), respectively. The detection rate of 63 GT1 samples without subtype were 93.7% (59/63), 37 indeterminate samples without genotype were 62.2 (23/37) by HCV GT Plus. 5' UTR sequencing confirmed HCV GT Plus characterized results for 84.7% (50/59) of type1, with 100% (4/4), 82.8 (24/29) and 84.6% (22/26) for 1a, 1b and type6; 65.2% (15/23) of indeterminate with 100% (3/3) and 60% (12/20) for 1b and type 6 samples, respectively. Conclusions The Abbott RealTime HCV GT Plus RUO assay provides additional performance in GT detection.

Abstract
Objective: To evaluate the airway and voice quality improvement in patients with bilateral vocal fold paralysis (BVFP) who underwent selective laryngeal reinnervation surgery. Methods: From January 2012 to December 2016, a retrospective study was conducted in 39 patients with BVFP who underwent selective laryngeal reinnervation surgery in Department of Otorhinolaryngology Head and Neck Surgery, the First Affiliated Hospital of Navy Medical University. All patients were examined by videostroboscopy, vocal function assessment, laryngeal electromyography and pulmonary function test before and after the surgery, and followed up for at least 2 years to evaluate the efficacy and safety of the surgery.Wilcoxon signed rank test was used to analyze the G score and VHI-10 score data. Paired t-test was used to analyze acoustic parameters, MPT values and pulmonary function parameters. Results: Postoperative infection and hemorrhage occurred in one patient separately.Videostroboscopic videos showed that at 4-8 months postoperatively, vocal folds in 35 patients achieved moderate or severe abduction during inspiration, 2 patients only achieved mild abduction, 2 patients showed no abduction,while all patients achieved adduction in bilateral vocal cords during phonation. The recovery rate of moderate-to-severe abduction was 89.7% (35/39), and these patients were decannulated successfully. At 12 months after operation, G score and VHI-10 score were significantly lower than those before operation (P<0.05), and the acoustic parameters jitter, shimmer, HNR and MPT were significantly improved (P<0.05). Most of the parameters of the pulmonary function test at 3 months postoperatively returned to the normal reference level, while the maximum inspiratory pressure (PImax) at 12 months after operation was still slightly lower than the normal level, but it was significantly improved compared with preoperative value (P<0.05). The EMG data at 12 months postoperatively showed full interference potentials in 37 patients in bilateral posterior cricoarytenoid muscles during inspiration, and full interference potentials in bilateralthyroarytenoid muscles during phonation. Obvious misdirected regeneration electric activitieswere found in two of them. Potentials in posterior cricoarytenoid muscle were weak in 2 cases with poor abduction. During long-term follow-up, only one case showed decreased abduction, but did not affect respiratory function. Conclusions: The selective laryngeal reinnervation procedure applied in the present study can restore physiological motion of vocal cords. The success rate was high, the curative effect was stable, and the complications were rare. It is worth of promotion.

Abstract
Whether patients with advanced hepatocellular carcinoma (aHCC) benefit from hepatitis C virus (HCV) eradication is uncertain. We aimed to investigate whether a survival benefit was conferred by HCV eradication in aHCC patients. This retrospective cohort study enrolled 168 HCV-infected aHCC patients from April 2013 to January 2019. All patients were treated with sorafenib. Endpoints included overall survival (OS), progression free survival (PFS), and time to liver decompensation. Patients with undetectable HCV RNA exhibited reduced aspartate aminotransferase and alpha fetoprotein levels, as well as an attenuated proportion of aHCC at initial diagnosis but increased albumin and mean sorafenib daily dosing. Patients with undetectable HCV RNA exhibited significantly longer OS compared to patients with detectable or unknown HCV RNA, which was an independent factor of OS (HR: 0.56, 95% CI: 0.350-0.903, P = .017). Patients with undetectable HCV RNA also presented a trend for longer PFS (HR 0.68, 95% CI: 0.46-1.00, P = .053). The survival benefit was considered with respect to the significantly prolonged time to Child-Pugh B scores in patients with undetectable HCV RNA (HR 0.59, 95% CI: 0.38-0.92, P = .020). Patients with detectable HCV RNA at sorafenib initiation who further received direct acting antiviral therapy also had significantly longer OS (HR 0.11, 95% CI: 0.02-0.81, P = .030) and PFS (HR 0.23, 95% CI: 0.06-0.99, P = .048). In conclusion, abolishing HCV viremia preserves liver function and confers a survival benefit in advanced HCC patients on sorafenib treatment.

Abstract
Both dengue virus (DENV) and hepatitis C virus (HCV) belong to the Flaviviridae family and could induce hepatitis. We aimed to investigate the interference between them. In total, 515 patients confirmed with dengue fever (DF) were enrolled. Thirty-two patients (6.21%) were seropositive for anti-HCV; 12 of 32 anti-HCV-positive patients had detectable HCV-RNA at presentation of DF. The proportion of dengue hemorrhagic fever was comparable between patients with or without anti-HCV and between those with or without HCV-RNA. Eleven of 32 patients received HCV-RNA testing during a median interval of 23 months after DF, which revealed significantly increased HCV-RNA levels (5.43 ± 0.77 vs 3.09 ± 1.24 log IU/mL, follow-up vs acute-DF phase; P = .003). Four of 11 patients with baseline HCV-RNA values before DF demonstrated a nadir viremia during acute DF. We also included age-, sex-, and follow-up duration–matched HCV-monoinfected patients as controls; higher delta HCV-RNA changes were demonstrated in patients with DF than in controls during the follow-up period (2.34 ± 1.15 vs –0.27 ± 0.76 log IU/mL; P < .001). Further in vitro experiments showed that HCV nonstructural protein 5A was downregulated in Con1 HCV replicon cells infected by DENV1. These clinical and experimental findings suggested possible viral interference in DENV/HCV. However, HCV viremia did not affect the disease outcomes of DF.

Abstract
BACKGROUND The features and risk analysis of non-alcoholic fatty liver disease (NAFLD) in a community-based setting remain elusive. The predictors between obese and lean subjects need further clarification. We aimed to assess the characteristics of NAFLD during a community screening. The associated metabolic abnormalities and cardiovascular risk assessment were also analyzed. METHODS A total of 2483 subjects receiving multi-purpose health screening at 10 primary care centers were recruited. They received clinical assessment, including demographic data, laboratory examination, and abdominal sonography. RESULTS The prevalence of NAFLD and metabolic syndrome were 44.5%, and 15.8%, respectively. Among those NAFLD subjects, 1212 (48.8%) subjects were obese (BMI≥ 24 kg/m2). There was an increasing trend of NAFLD according to age, ranging from 25.8% of those aged <30 years to 54.4% of those aged 50-70 years (P for trend< 0.0001). High insulin resistance (IR) was the significant predictive factor for NAFLD in both obese (odds ratio [OR] = 3.85, 95% confidence interval [CI] = 1.87-8.36, P = 0.0002) and lean subjects (OR = 2.52, 95% CI = 1.13-5.54, p = 0.02). The prevalence of high Framingham Risk Score (≥7.5%) was 56.7% (211/372) among the male subjects, which was significantly higher than that (26%, 191/734) of the females (P < 0.001). There was a significant increase of high Framingham Risk Score according to BMI, ranging from 23.1% of BMI<24 kg/m2 to 45% of BMI>27 kg/m2 (P for trend< 0.0001). CONCLUSION IR is predictive of NAFLD irrespective of BMI. The cardiovascular risk may exist in lean NAFLD subjects.

Methods: Experimental study. The permeability of the cornea and sclera in healthy male New Zealand rabbits was evaluated by using Franz diffusion pool. We chose both gatifloxacin ophthalmic solution and gel as the test drugs, and calculated the cumulative permeation amounts (Qn), apparent permeability coefficient(P(app)). Results: The linear range of gatifloxacin was 5-1 000 ng/ml. The intra-day and inter-day precision was 1.7% -2.8% and 1.0% - 2.3%. Q(n) and P(app) of gatifloxacin ophthalmic solution in cornea and sclera ex vivo were 177.57, 517.52 μg/cm(2) and 4.34, 12.51 cm/s respectively, whereas that of gatifloxacin ophthalmic gel were 151.87, 411.05 μg/cm(2) and 3.66, 9.21 cm/s. Conclusion: This validated method could be applied to determine the gatifloxacin. The cumulative permeation amounts and apparent permeability coefficient of sclera are significantly higher than that of cornea for both ophthalmic solution and gel, suggesting that the development of a new route of drug administration based on sclera may have potential advantage.

Abstract
The effectiveness of using gamma poly-glutamic acid (γ-PGA) as the primary carbon and nitrogen sources to bioremediate trichloroethene (TCE)-contaminated groundwater was studied in this pilot-scale study. γ-PGA (40 L) solution was injected into the aquifer via the injection well (IW) for substrate supplement. Groundwater samples were collected from monitor wells and IW and analyzed for TCE and its byproducts, geochemical indicators, dechlorinating bacteria, and microbial diversity periodically. Injected γ-PGA resulted in an increase in total organic carbon (TOC) (up to 9820 mg/L in IW), and the TOC biodegradation caused the formation of anaerobic conditions. Increased ammonia concentration (because of amine release from γ-PGA) resulted in the neutral condition in groundwater, which benefited the growth of Dehalococcoides. The negative zeta potential and micro-scale diameter of γ-PGA allowed its globule to distribute evenly within soil pores. Up to 93% of TCE removal was observed (TCE dropped from 0.14 to 0.01 mg/L) after 59 days of γ-PGA injection, and TCE dechlorination byproducts were also biodegraded subsequently. Next generation sequence (NGS) analyses were applied to determine the dominant bacterial communities. γ-PGA supplement developed reductive dechlorinating conditions and caused variations in microbial diversity and dominant bacterial species. The dominant four groups of bacterial communities including dechlorinating bacteria, vinyl chloride degrading bacteria, hydrogen producing bacteria, and carbon biodegrading bacteria.

Abstract
A total of 1 685 school-age children selected from Hangzhou received lung function testing to evaluate the short-term effects of air pollution on their lung function. The results showed that in every 10 μg/m(3) increase of average concentration of PM(2.5) and PM(10) on the day of the test and the day before the test,peak expiratory flow (PEF) decreased 0.039 (95%CI: 0.012-0.067) L/s and 0.031 (95% CI:0.011-0.051) L/s,respectively. When the average concentration of SO(2) increased 10 μg/m(3) on the day of test and the day prior to the test, PEF and 75% of the forced vital capacity that has not been exhaled (MEF(75)) decreased 0.437 (95%CI: 0.217-0.658) L/s and 0.396 (95%CI: 0.180-0.613) L/s. After being adjusted for NO(2),with every 10 μg/m(3) increase of average concentration of PM(2.5) and PM(10) on the day of the test and the day before the test,PEF and MEF(75) decreased 0.056 (95%CI: 0.028-0.085), 0.053(95%CI: 0.027-0.081) and 0.047 (95%CI: 0.026-0.068) L/s,0.044 (95%CI: 0.023-0.065) L/s on the day before the test, respectively. The results indicate that air pollution have short-term and lag effects on lung function of school-age children in Hangzhou.

Abstract
BACKGROUND Wisteria floribunda agglutinin-positive Mac-2-binding protein (WFA+-M2BP) was a novel marker of liver fibrosis. We aimed to investigate WFA+-M2BP level in assessing liver fibrosis in patients with chronic hepatitis B (CHB) infection. METHODS A total of 160 CHB patients, who received a liver biopsy, were consecutively recruited. Serum WFA+-M2BP level was quantified at the time point of biopsy. The results were compared with histopathological manifestations and clinical characteristics of the patients. RESULTS The median WFA+-M2BP level, aspartate aminotransferase-to-platelet ratio (APRI) and Fibrosis-4 (FIB-4) index were 1.20 COI, 1.19, and 1.63, respectively. Fifty-one (31.9%) patients had advanced fibrosis. There was a significant increase of WFA+-M2BP levels in parallel to necroinflammation/fibrosis stages. The areas under the receiver operating characteristic curve (AUROC) of WFA+-M2BP level for predicting fibrosis stages were 0.780 of F2, 0.785 of F3, and 0.769 of F4, respectively (all p <0.001). The multivariate analysis identified age (Odds ratio [OR] 1.05, 95% confidence interval [CI]: 1.010-1.092, p = 0.014), platelet (OR: 0.99, 95%CI: 0.980-0.998, p = 0.013), and WFA+-M2BP level (OR: 1.97, 95% CI: 1.299-2.984, p = 0.001) as independent factors associated with advanced fibrosis. Combination of age, platelet and WFA+-M2BP level achieved a better diagnostic performance for advanced fibrosis (AUROC: 0.732, accuracy: 81.3%) than APRI (AUROC: 0.577, accuracy: 63.8%) or FIB-4 index (AUROC: 0.691, accuracy: 75.6%). CONCLUSION WFA+-M2BP had a good performance indistinguishing liver fibrosis in CHB patients. The combination of age, platelet, and WFA+-M2BPaddressed more accuracy in identifying patients with advanced fibrosis.

Abstract
Sorafenib is currently the first-line therapy for advanced hepatocellular carcinoma (aHCC) patients. However, the outcomes and prognostic factors of sorafenib therapy have not been well investigated. We aimed to investigate the pretreatment factors and outcomes among Taiwanese aHCC patients receiving sorafenib treatment. A total of 347 patients with aHCC and well-compensated liver cirrhosis (Child-Pugh A) status receiving sorafenib were consecutively enrolled from March 2013 through December 2016. Pre-treatment clinical data and viral hepatitis markers were collected and analyzed with their outcomes. The primary endpoint of the study was overall survival. The factors associated with overall survival were also investigated. The median overall survival of all the patients was 238 days (range, 9-1504 days) with a 1-year overall survival of 43.2%. Positive hepatitis B surface antigen and absence of portal vein thrombosis (PVT) were independent factors associated with better overall survival. The median duration of sorafenib therapy was 93.0 days (range, 4-1504 days). After stopping sorafenib, the median survival was 93.0 days (range, 1-1254 days). The 1-year survival after stopping sorafenib was 21.2%. In chronic hepatitis B patients, total bilirubin level was the only factor associated with overall survival. Hepatitis C antibody RNA negativity, tumor size, PVT, and white blood cell count were the independent factors associated with survival among those chronic hepatitis C patients. There were different prognostic factors stratified by viral etiologies in aHCC patients receiving sorafenib. Viral eradication increased survival in chronic hepatitis C patients.

Abstract
OBJECTIVES Nonalcoholic steatohepatitis (NASH) might progress to fibrosis, cirrhosis, and hepatocellular carcinoma. However, the natural history of NASH has not been fully clarified. This study aimed to investigate the disease progression in NASH patients receiving paired liver biopsies. We also aimed to examine the factors associated with NASH progression. PATIENTS AND METHODS Ten NASH patients who had received liver biopsies during June 2001 and February 2010 were consecutively enrolled. The histopathological changes were examined retrospectively, including nonalcoholic fatty liver disease activity score (NAS) and fibrosis stage. The associated clinical profiles were also analyzed. RESULTS The median duration between paired biopsies was 20.5 months (range: 12-106 months). According to NAS and fibrosis stage, disease progression, stable disease, and disease regression were observed in seven patients, two patients, and one patient, respectively. Six (60%) patients had increased NAS on second biopsy, and two were lean NASH patients. The only patient with an improvement in NAS had achieved body weight reduction (13.3%) between paired biopsies. None of the 10 patients experienced an improvement in fibrosis. Five (50%) patients showed progression of fibrosis on second biopsy and the annual fibrosis progression rate was 0.32/year. Two of the five patients who showed progression of fibrosis were of the nonobese phenotype, whereas three patients were nondiabetic. CONCLUSION NASH is a progressive disease in Taiwanese patients. The disease progression should be further clarified in lean and nondiabetic NASH patients.

Abstract
BACKGROUND Chronic pruritus (CP) is a frequently occurring symptom in inflammatory dermatoses, causing a high burden and limitations to health-related quality of life (HRQoL). OBJECTIVE The ItchyQoL was developed to assess the impairment to HRQoL in patients with CP. However, it has only been validated in English and German. Here, we report the validation in several languages across Europe. METHODS After professional translation, the versions of ItchyQoL were digitized for use as a tablet application. Validation was performed in clinics for dermatology in Austria, France, Germany, Italy, Poland, Russia, Spain, Switzerland and Turkey. RESULTS Five hundred and thirty-five patients with either contact dermatitis, chronic prurigo - nodular type, psoriasis vulgaris, lichen planus or mycosis fungoides/Sézary syndrome and with CP ≥ 3 on the numerical rating scale were included. ItchyQoL showed a high level of consistency (Cronbach's-α, all: 0.95) and test-retest reliability (intraclass correlation: 0.91). It strongly correlated with the Dermatology Life Quality Index (r = 0.72, P < 0.001) and moderately correlated with itch intensity scales in the study population (visual analogue scale r = 0.46; numerical rating scale r = 0.51; verbal rating scale r = 0.51, for all: P < 0.001). CONCLUSION ItchyQoL is now also validated in French, Italian, Polish, Russian, Spanish and Turkish and can be used in clinical trials in countries speaking these languages.

Abstract
Utilization of bacterial volatilization can be problematic to remediate mercury (Hg)-contaminated soils because most of the Hg in soils is bound to soil particles. The objective of this study was to develop a two-stage system (chemical extraction followed by microbial reduction) for Hg-contaminated soil remediation. The tasks were to (1) select the extraction reagents for Hg extraction, (2) assess the effects of extraction reagents on the growth of Hg-reducing bacterial strains, and (3) evaluate the effectiveness of Ca2+ and Mg2+ addition on merA gene (Hg reductase) induction. Bacterial inhibition was observed with the addition of 0.1 M ethylenediaminetetraacetic acid or citric acid. Up to 65% of Hg was biotransformed (Hg concentration = 69 mg/kg) from the soils after a 24 h extraction using 0.5 M ammonium thiosulfate. Ca2+ and Mg2+ were selected because they have the same electric charge as Hg and the studied groundwater contained high concentrations of Ca2+ and Mg2+. Results showed that the addition of 200 mg/L Ca2+ or 650 mg/L Mg2+ could reach effective merA induction. In the two-stage experiment, 120 mg/kg Hg-contaminated soils were extracted with 2 rounds of extraction processes for 10 h using 0.5 M ammonium thiosulfate. Approximately 77% of Hg was extracted from the soils after the first-step extraction process. Up to 81% of Hg2+ was transformed from the washing solution via the biotransformation processes with Enterobacter cloacae addition and Ca2+ and Mg2+ supplementation. The two-stage remedial system has the potential to be developed into a practical technology to remediate Hg-contaminated sites.

Abstract
Objective: To identify the cause on a foodborne breakout in a university of Hangzhou in 2014. Methods: Data on cases were gathered from the out-patient logs of the university affiliated or neighboring hospitals to describe the disease distribution and epidemiological curves. Case-control and field studies on hazard factors were conducted simultaneously. Results: The incubation period was 1.5-5.0 hours, of which the median was 3 during the outbreak. All the cases consumed food from a restaurant called Chen's Snacks nearby their university and suffered from the Staphylococcus aureus enterotoxin. Results from the Staphylococcus enterotoxin testing were positive in 3 stool and 6 food samples, out of the total 18 samples. Conclusion: This foodborne outbreak was caused through food poisoning by vermicelli which was contaminated with Staphylococcus aureus.

Abstract
AIM 25-Hydroxy vitamin D (Vit D) plays a role in treatment outcomes in chronic hepatitis C virus (HCV) infection. We aimed to clarify whether HCV replication is inhibited by Vit D in HCV replicon cells. Clinical implication was assessed for rapid virological response (RVR) and sustained virological response (SVR) among those patients receiving antiviral therapy. METHODS Cell survival and viral loads were observed in Con1 (genotype 1b) and J6/JFH (genotype 2a) cells treated with different doses of Vit D. Three groups of patients with different treatment responses were recruited to assess their Vit D levels: group A, RVR-/SVR-; group B, RVR+/SVR-; and group C, RVR+/SVR+. RESULTS The viral load of Con1 cells decreased by 69%, 80%, and 86% following treatment with 1 μM, 5 μM, and 10 μM Vit D, respectively (P < 0.0001). In J6/JFH cells, it decreased by 12%, 55%, and 80.5% following treatment with 1 μM, 5 μM, and 10 μM Vit D, respectively (P < 0.0001). There was a significant increase of Vit D between chronic hepatitis C groups, ranging from 4.4 ± 5.6 ng/mL in group A (n = 44), to 17.2 ± 11.6 ng/mL in group B (n = 44), and 32.5 ± 37.5 ng/mL of group C (n = 44) (P < 0.001). Advanced fibrosis (odds ratio = 0.13, 95% confidence interval = 0.04-0.41, P < 0.001) and Vit D deficiency (<10 ng/mL) (odds ratio = 0.11, 95% confidence interval = 0.03-0.43, P = 0.001) were predictive of SVR in the multivariate regression analysis. CONCLUSION Vitamin D decreases HCV replication and also contributes to early treatment viral kinetics.

Abstract
Objective:To evaluate the feasibility and long-term outcome of radiofrequency coblation combined with silicon stent implantation in the treatment of recurrent laryngeal papilloma with extensive lesions. Method:From March 2009 to April 2016, a total of 13 patients (8 males, 5 females; aged 28-67 years) who suffered recurrent laryngeal papilloma were enrolled in this retrospective study. All the cases had undergone at least one operation at other hospitals before this hospitalization. The recurrence interval (RI) of these cases ranged from 2 to 6 months. Video-laryngoscopy or stroboscopy were preformed preoperatively and postoperatively, as well as vocal function assessment. These cases underwent radiofrequency coblationin combination of different stent implantation (member, 7 cases; tube, 4 cases; T-shaped tube, 2 cases) under general anesthesia. The follow-up was 12 to 76 months. Result:Laryngoscopy revealed that the lesions mainly located in the vocal folds, anterior commissure, ventricular band, posterior commissure, epiglottis and even in subglottic area. Varying extent of mucosal adhesion of anterior or/and posterior commissure were observed in all cases, and two cases suffered mild subglottic tracheal stenosis. Two to six weeks after surgery, the silicon stent were removed and no mucosal adhesion were found except for 2 cases who suffered mucosal adhesion of anterior commissure again. Compared to preoperative scores, VHI-10 and G scores showed the significant improvement of voice quality postoperatively in all cases. The recurrence of papilloma was observed in 3 cases during 1-year follow-up, and 4 cases during 2-year follow-up, no recurrence in 6 cases. These recurrence lesions mainly located in ventricular band, subglottic area and trachea. However, no recurrence occurred in these cases who received ablation again. No serious complications were observed in these cases. Conclusion:Radiofrequency ablation may be an effective approach in the treatment of recurrent laryngeal papilloma with extensive lesions. One-stage application of suitable silicon stents can effectively prevent the adhesion of the wound and the onset oflaryngo-tracheal stenosis, and improve the quality of voice.

Abstract
Direct-acting antiviral agents (DAAs) have been widely used for chronic hepatitis C (CHC) treatment recently. The characteristics of glucose abnormalities after DAAs therapy however, remain elusive. We aimed to elucidate the mutual impact between treatment response and parameters of glucose abnormalities after DAAs therapy in CHC patients. CHC patients who received DAAs therapy were recruited. The primary outcome measurements were their insulin resistance (IR) and beta-cell function assessed by the homeostasis model assessment (HOMA) method before treatment and at end-of-follow-up (EOF). Sixty-five CHC patients (19 males, mean age = 59.8 ± 10.3 years) were consecutively enrolled. They included 47 (72.3%) patients of genotype-1 infection. The treatment regimens among patients were sofosbuvir in 30 patients, paritaprevir-ritonavir/ombitasvir/dasabuvir in 23 patients, and asunaprevir/daclatasvir in 12 patients respectively. The overall sustained virological response rate was 98.5%. The mean IR at EOF was 2.6 ± 1.8, which was not significantly different from baseline level (2.7 ± 2.9, P = 0.75). There was a significant improvement of beta-cell function at EOF compared to baseline (107.7 ± 86.8 to 86.7 ± 44.5, P = 0.05). The amelioration of beta-cell function at EOF was significantly observed among 23 patients of high baseline IR (166.7 ± 111.3 of baseline vs 105.7 ± 48.2 of EOF, P = 0.04). Six (60%) of the 10 pre-diabetic patients at baseline achieved a normoglycemic state at EOF. Successful eradication of HCV by DAAs might improve glucose abnormalities in CHC patients, particularly among those who had high IR.

Abstract
Intracranial hypertension leading to brain stem herniation is a major cause of death in fulminant hepatic failure (FHF). Mannitol, barbiturates, and hyperventilation have been used to treat brain swelling, but most patients are either refractory to medical management or cannot be treated because of concurrent medical problems or side effects. In this study, we examined whether allogeneic hepatocellular transplantation may prevent development of intracranial hypertension in pigs with experimentally induced liver failure. Of the two preparations tested—total hepatectomy (n = 47), and liver devascularization (n = 16)—only pigs with liver ischemia developed brain edema provided, however, that animals were maintained normothermic throughout the postoperative period. This model was then used in transplantation studies, in which six pigs received intrasplenic injection of allogeneic hepatocytes (2.5 × 109 cells/pig) and 3 days later acute liver failure was induced. In both models (anhepatic state, liver devascularization), pigs allowed to become hypothermic had significantly longer survival compared to those maintained normothermic. Normothermic pigs with liver ischemia had, at all time points studied, ICP greater than 20 mmHg. Pigs that received hepatocellular transplants had ICP below 15 mmHg until death; at the same time, cerebral perfusion pressure (CPP) in transplanted pigs was consistently higher than in controls (45 ± 11 mmHg vs. 16 ± 18 mmHg; p < 0.05). Spleens of transplanted pigs contained clusters of viable hepatocytes (hematoxylin-eosin, CAM 5.2). It was concluded that removal of the liver does not result in intracranial hypertension; hypothermia prolongs survival time in both anhepatic pigs and pigs with liver devascularization, and intrasplenic transplantation of allogeneic hepatocytes prevents development of intracranial hypertension in pigs with acute ischemic liver failure.

Abstract
This case-control study aimed to assess the interactive effect between polymorphisms of lymphotoxin (LT) α +252 and habitual substance use on risk of hepatocellular carcinoma (HCC). We enrolled 150 pairs of sex- and age-matched HCC patients and unrelated healthy controls. LTα genotypes were detected with polymerase-chain reaction and restrictive fragment length polymorphisms. Information about habits of substance use was obtained through personal interview. Multivariate analysis indicated that LTα +252 G/G genotypes [odds ratio (OR) = 3.36], Hepatitis B surface antigen (OR = 16.68), antibodies to hepatitis C virus (OR = 34.88) and having at least two habits of substance use (OR = 2.50) were independent risk factors for HCC. There were additive interactions among LTα +252 G/G genotype, chronic viral hepatitis, and habit of each substance use. IN CONCLUSION There are independent and additive interactions between LTα +252 G/G genotype, chronic viral hepatitis, and habits of substance use on risk of HCC.

Abstract
This case-control study was aimed to assess the effect of genetic variants of tumor necrosis factor (TNF) α-308 and lymphotoxin (LT) α+252 on development of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). Their gene-gene interaction was also investigated. We enrolled 200 pairs of age- and sex-matched patients with cirrhotic HBV-HCC and unrelated patients with HBV-cirrhosis alone. Polymorphisms of TNFα-308 and LTα+252 were genotyped. Synergy index was used to calculate interaction between the variant genotypes. The results indicated that the frequency distribution of the variant genotypes (TNFα-308 G/A and LTα+252 G/G) in patients with HCC were significantly higher than those in patients with cirrhosis alone. Multivariate analysis indicated that TNFα-308 G/A (odds ratio [OR], 2.34) and LTα+252 G/G (OR, 2.04) were independent risk factors for HCC. By the clinical characteristics of study population, multivariate analysis demonstrated that independent factors associated with harboring the variant genotypes included cirrhosis with Child-Pugh C (OR = 6.47 in cases and OR = 11.56 in controls) and thrombocytopenia (OR = 8.86 in cases and OR = 7.74 in controls). Calculation of synergy index (SI) indicated that there are additive interaction between TNFα-308 G/A and LTα+252 G/G on risk of HCC (SI = 1.29). IN CONCLUSION There are independent and additive interactions between TNFα-308 G/A and LTα+252 G/G on risk for HBV-HCC. They correlated with advanced hepatic fibrosis and severe liver damage, which might contribute to a higher risk for HCC.

Abstract
BACKGROUND & AIMS Identification of disease severity remains a challenge in the management of non-alcoholic steatohepatitis (NASH). Cytokeratin-18 (CK18), is a recently developed non-invasive biomarker for NASH. We aimed to assess the performance of CK18 in disease severity prediction among Taiwanese NASH patients. METHODS A total of 76 biopsy-proven NASH patients (54 males, age = 41.0 ± 13.5 years) were consecutively recruited. The optimal cutoff values of CK18 for each stage of fibrosis were correlated with their histopathological manifestations. RESULTS There were 23 (30.3%) patients of Metavir fibrosis stage 0 (F0), 32 (42.1%) patients of F1, 14 (18.4%) patients of F2, and 7 (9.2%) patients of F3-4, respectively. The CK18 levels among those patients of F0, F1, F2, F3-4 were 86.7 ± 75.6 U/L, 122.4 ± 123.8 U/L, 160.7 ± 120.4 U/L, and 507.3 ± 343 U/L, respectively (trend for P<0.001). The adjusted optimal cutoff value for F2 prediction was 312.5 U/L, yielding the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and the accuracy of 96.4%, 28.6%, 77.9%, 75%, and 77.6%, respectively (P = 0.009). For the prediction of advanced fibrosis (F3-4), the adjusted optimal cutoff value was 374.5 U/L, yielding the sensitivity, specificity, PPV, NPV, and the accuracy of 97.1%, 54.1%, 95.7%, 66.7%, and 77.6%, respectively (P = 0.003). Among those patients without hyperuricemia, the PPV, NPV, and accuracy of CK18 reached 100%, 95.8%, and 96%, respectively (P<0.001). CONCLUSIONS CK18 combined with uric acid measurement is a promising non-invasive biomarker for prediction of disease severity in NASH patients. TRIAL REGISTRATION ClinicalTrials.gov NCT01068444.

Abstract
The subsequent maintenance therapy in chronic hepatitis B (CHB) patients after long-term viral replication suppression is still uncertain. We aim to evaluate the efficacy of lamivudine (LAM) maintenance therapy in CHB patients achieving undetectable hepatitis B virus (HBV) DNA after 3 years of entecavir (ETV) therapy. Consecutive CHB patients who received at least 3 years of ETV and achieved HBV DNA negativity were allocated either LAM switch therapy or stopped ETV therapy in a prospective, open-label study. Another group of sex- and age-matched patients with continuous ETV therapy for at least 4 years served as historical control group. The primary outcome measurement of the study was relapse of HBV DNA (defined as serum HBV DNA level ≥ 2000 IU/mL). A total of 74 patients, including 42 of LAM switch and 32 of the nonswitch group, were enrolled. There were no significant differences in demographics, except a higher proportion of patients with positive hepatitis B envelope antigen in the nonswitch group at the initiation of ETV therapy. The LAM switch group had significantly lower 1-year relapse rate of HBV within 1 year compared to the nonswitch group (14.3% vs. 75%, p<0.001). However, none of the 48 historical control patients developed relapse of HBV, which was significantly lower than the rate in LAM switch group (p < 0.001). LAM switch was the only factor associated with HBV DNA relapse. In conclusion, continuous long-term potent nucleot(s)ide analogue therapy is mandatory for prevention of viral relapse in CHB patients.

Abstract
To enhance the reductive dechlorination of 1,2-dichloroethane (DCA) in groundwater, substrate injection may be required. However, substrate biodegradation causes groundwater acidification and sulfide production, which inhibits the bacteria responsible for DCA dechlorination and results in an odor problem. In the microcosm study, the effectiveness of the addition of ferrous sulfate (FS), desulfurization slag (DS), and nanoscale zero-valent iron (nZVI) on acidification and sulfide control was studied during reductive dechlorination of DCA, and the emulsified substrate (ES) was used as the substrate. Up to 94% of the sulfide was removed with FS and DS addition (0.25 wt%) (initial DCA concentration = 13.5 mg/L). FS and DS amendments resulted in the formation of a metal sulfide, which reduced the hydrogen sulfide concentration as well as the subsequent odor problem. Approximately 96% of the DCA was degraded under reductive dechlorination with nZVI or DS addition using ES as the substrate. In microcosms with nZVI or DS addition, the sulfide concentration was reduced to less than 15 μg/L. Acidification can be controlled via hydroxide ions production after nZVI oxidation and reaction of free CaO (released from DS) with water, which enhanced DCA dechlorination. The quantitative polymerase chain reaction results confirmed that the microcosms with nZVI added had the highest Dehalococcoides population (up to 2.5 × 10(8) gene copies/g soil) due to effective acidification control. The α-elimination mechanism was the main abiotic process, and reductive dechlorination dominated by Dehalococcides was the biotic mechanism that resulted in DCA removal. More than 22 bacterial species were detected, and dechlorinating bacteria existed in soils under alkaline and acidic conditions.

Abstract
Objective:To investigate the application of the reconstruction methods for hypopharyngeal and cervical esophageal defects due to the resection of hypopharyngeal cancer and advanced laryngeal cancer between free fasciocutaneous flaps and free jejunium transfer.We compared the superiorities and inferiorities of these two reconstruction methods. Method:Retrospective review of the archives of 56 patients from 2000 to 2010 who underwent pharyngoesophageal reconstruction with free flaps (n=32) or free jejunal transfer(n=24),comparison of indications,complications, hospitalization duration, swallowing function recovery and postoperative survival time. Result:The overall 3 year survival rate of free flap group and free jejunal transfer group was 59.3%,55.7% respectively; the overall 5 year survival rate was 38.5%,37.1% respectively. The overall rate of complication rate was 18.8%, 16.7% respectively. The patients with free flaps had higher incidence rate of fistula and scarring in the donor site and lower incidence rate of hues and stricture than the ones with free jejunal transfers. The mean hospitalization duration was (15.00±7.06) days and(13.00±6.75) days. The mean time of first oral food intake was(13.00±5.83)days and (11.00±6.67) days. The differences between two groups had no statistical significance(P>0.05). Conclusion:Free flaps and free jejunium transfer are the two most common reconstruction methods for the hypopharyngeal and cervical esophageal defects. Each has its own advantages and disadvantages respectively. We should choose reconstruction method according to the site and extent of the hypopharyngeal and cervical esophageal defects, preoperative and postoperative radiotherapy requirement.

Abstract
Background & Aims Asians are more susceptible to non-alcoholic steatohepatitis (NASH) as well as metabolic disorder than other ethnicities. We aimed to assess the interaction between metabolic factors and fibrosis in Taiwanese NASH patients. Methods A total of 130 biopsy-proven Taiwanese NASH patients (94 males, age = 43.0 ± 13.0 years) were consecutively enrolled. Their demographic, metabolic profiles and histopathological manifestations were analyzed. Results Twenty-four (18.5%) NASH patients were non-obese. Thirty-three (25.4%) patients had significant fibrosis (F2) or more: 22 (16.9%) patients were of F2, whilst 11 (8.5%) patients were of advanced fibrosis (F3-4). The prevalence of metabolic syndrome, diabetes and hypertension were 60.8%, 39.4%, and 61.5%, respectively. There was a significant inverse correlation between hyperuricemia and fibrosis stages, ranging from 48.4% of F0-1, 33.3% of F2, and 9.1% of F3-4, respectively (P = 0.01, linear trend). Multivariate logistic regression analysis showed that a decreased serum albumin level (OR = 40.0, 95% CI = 4.5–300, P = 0.001) and normal uric acid level (OR = 5.6, 95% CI = 1.5–21.7, P = 0.01) were the significant factors associated with significant fibrosis. Conclusions Hyperuricemia inversely predicts fibrosis stages. Females might carry a more disease severity than males in Taiwanese NASH patients.

Abstract
This article introduces the second revision of the Australian and New Zealand consensus guidelines for the use of antifungal agents in the haematology/oncology setting. The current update occurs within the context of a growing population at risk of invasive fungal disease, improved understanding of risk factors, availability of new diagnostic tests, a much-expanded evidence base and changing clinical paradigms. Here, we provide an overview of the history and purpose of the guidelines, including changes in scope since the last clinical update was published in 2008. The process for development, and for enabling review of draft recommendations by end-users and other relevant stakeholders, is described. The approach to assigning levels of evidence and grades of recommendation is also provided, along with a comparison to international grading systems.

Abstract
Pathogenic yeast forms are commonly associated with invasive fungal disease in the immunocompromised host, including patients with haematological malignancies and patients of haemopoietic stem cell transplants. Yeasts include the Candida spp., Cryptococcus spp., Pneumocystis jirovecii and some lesser-known pathogens. Candida species remain the most common cause of invasive yeast infections (and the most common human pathogenic fungi). These guidelines present evidence-based recommendations for the antifungal management of established, invasive yeast infections in adult and paediatric patients in the haematology/oncology setting. Consideration is also given to the critically ill patient in intensive care units, including the neonatal intensive care unit. Evidence for 'pre-emptive' or 'diagnostic-driven antifungal therapy' is also discussed. For the purposes of this paper, invasive yeast diseases are categorised under the headings of invasive candidiasis, cryptococcosis and uncommon yeast infections. Specific recommendations for the management of Pneumocystis jirovecii are presented in an accompanying article (see consensus guidelines by Cooley et al. appearing elsewhere in this supplement).
