Abstract
BACKGROUND The efficacy of washed microbiota transplantation (WMT) in terms of refractory functional constipation (FC)-related therapeutic targets and influencing factors have not been elucidated. This study aimed to assess the efficacy and influencing factors of WMT in treating refractory FC-related therapeutic targets. METHODS The clinical data of patients diagnosed with refractory FC and received with WMT were retrospectively collected. The therapeutic targets included straining, hard stools, incomplete evacuation, a sense of anorectal obstruction, manual maneuvers, and decreased stool frequency. Each target was recorded as 1 (yes) or 0 (no). All patients were followed up for approximately 24 weeks from the end of the first course of WMT. The primary outcomes were the improvement rates for the individual therapeutic targets and the overall response in respect of the therapeutic targets decreased by 2 at weeks 4, 8, and 24. The secondary outcomes were the clinical remission rate (i.e., the proportion of patients with an average of 3 or more spontaneous complete bowel movements per week), clinical improvement rate (i.e., the proportion of patients with an average increase of 1 or more SCBMs/week or patients with remission), stool frequency, Wexner constipation score, Bristol Stool Form Scale (BSFS) score, and adverse events. The factors influencing the efficacy were also analyzed. RESULTS Overall, 63 patients with 112 WMT courses were enrolled. The improvement rates at weeks 8 and 24 were 45.6% and 35.0%, 42.9% and 38.6%, 45.0% and 35.7%, 55.6% and 44.4%, and 60.9% and 50.0%, respectively, for straining, hard stools, incomplete evacuation, a sense of anorectal obstruction, and decreased stool frequency. The overall response rates were 49.2%, 50.8%, and 42.9%, respectively, at weeks 4, 8, and 24. The rates of clinical remission and clinical improvement were 54.0% and 68.3%, respectively, at weeks 4. The stool frequency, BSFS score, and Wexner constipation score tended to improve post-WMT. Only 22 mild adverse events were observed during the 112 WMT courses and the follow-up. The number of WMT courses was identified to be the independent factor influencing the efficacy. CONCLUSIONS WMT is efficacious in improving refractory FC-related therapeutic targets. The effectiveness of WMT in the management of FC is enhanced with the administration of multiple courses.

Abstract
BACKGROUND AND AIM Over 10% of hepatocellular carcinoma (HCC) cases recur each year, even after surgical resection. Currently, there is a lack of knowledge about the causes of recurrence and the effective prevention. Prediction of HCC recurrence requires diagnostic markers endowed with high sensitivity and specificity. This study aims to identify new key proteins for HCC recurrence and to build machine learning algorithms for predicting HCC recurrence. METHODS The proteomics data for analysis in this study were obtained from the Clinical Proteomics Tumor Analysis Consortium (CPTAC) database. We analyzed different proteins based on cases with or without recurrence of HCC. Survival analysis, Cox regression analysis, and area under the ROC curves (AUROC > 0.7) were used to screen for more significant differential proteins. Predictive models for HCC recurrence were developed using four machine learning algorithms. RESULTS A total of 690 differentially expressed proteins between 50 relapsed and 77 non-relapsed hepatitis B-related HCC patients were identified. Seven of these proteins had an AUROC > 0.7 for 5-year survival in HCC, including BAHCC1, ESF1, RAP1GAP, RUFY1, SCAMP3, STK3, and TMEM230. Among the machine learning algorithms, the random forest algorithm showed the highest AUROC values (AUROC: 0.991, 95% CI 0.962-0.999) for identifying HCC recurrence, followed by the support vector machine (AUROC: 0.893, 95% Cl 0.824-0.956), the logistic regression (AUROC: 0.774, 95% Cl 0.672-0.868), and the multi-layer perceptron algorithm (AUROC: 0.571, 95% Cl 0.459-0.682). CONCLUSIONS Our study identifies seven novel proteins for predicting HCC recurrence and the random forest algorithm as the most suitable predictive model for HCC recurrence.

Abstract
OBJECTIVE Mortality-trends from alcoholic liver disease (ALD) have recently increased and they differ by various factors in the U.S. However, these trends have only been analyzed using univariate models and in reality they may be influenced by various factors. We thus examined trends in age-standardized mortality from ALD among U.S. adults for 1999-2017, using multivariable piecewise log-linear models. METHODS We collected mortality-data from the Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research database, using the Underlying Cause of Death. RESULTS We identified 296,194 deaths from ALD and 346,386 deaths indirectly attributable to ALD during the period from 1999-2017. The multivariable-adjusted, age-standardized ALD mortality was stable during 1999-2006 (annual percentage change [APC]=-2.24, P=0.24), and increased during 2006-2017 (APC=3.18, P<0.006). Their trends did not differ by sex, race, age or urbanization. Subgroup analyses revealed upward multivariable-adjusted, age-standardized mortality-trends in alcoholic fatty liver (APC=4.64, P<0.001), alcoholic hepatitis (APC=4.38, P<0.001), and alcoholic cirrhosis (APC=5.33, P<0.001), but downward mortality-trends in alcoholic hepatic failure (APC=-1.63, P=0.006) and unspecified ALD (APC=-0.86, P=0.013). Strikingly, non-alcoholic cirrhosis also had an upward multivariable-adjusted, age-standardized mortality-trend (APC=0.69, P=0.046). By contrast, recent mortality-trends were stable for all cause of deaths (APC=-0.39, P=0.379) and downward for malignant neoplasms excluding liver cancer (APC=-2.82, P<0.001), infections (APC=-2.60, P<0.001), cardiovascular disease (APC=-0.69, P=0.044) and respiratory disease (APC=-0.56, P=0.002). The adjusted mortality with ALD as a contributing cause of death also had an upward trend during 2000-2017 (APC=5.47, P<0.001). Strikingly, common comorbidities of ALD, including hepatocellular carcinoma, cerebrovascular and ischemic heart cardiovascular diseases and sepsis, had upward trends during the past 14 to 16 years. CONCLUSIONS ALD had an upward multivariable-adjusted, age-standardized mortality-trend among U.S. adults, without significant differences by sex, race, age or urbanization. Three ALD subtypes (alcoholic fatty liver, alcoholic hepatitis and alcoholic cirrhosis) and non-alcoholic cirrhosis had upward morality-trends, while other ALD subtypes and other causes of death did not.

Abstract
INTRODUCTION Gut dysbiosis has been reported to be closely associated with gout. Washed microbiota transplantation (WMT) is considered as an effective way to restore a healthy gut microbiota with less adverse events than the conventional fecal microbiota transplantation. In this study, we aimed to evaluate the effects of WMT on serum uric acid levels, symptoms, and the intestinal barrier function in patients with acute and recurrent gout. METHODS We performed a pilot study of WMT for acute and recurrent gout. The primary outcome was the changes in the serum uric acid level and gout symptoms. The secondary outcomes included the changes in levels of diamine oxidase (DAO), D-lactic acid, and endotoxin. RESULTS Eleven patients received WMT treatment. The averaged serum uric acid levels in patients with gout reduced after WMT (p = 0.031), accompanied with a decrease in the frequency and duration time of acute gout flares (p < 0.01). The levels of DAO, D-lactic acid, and endotoxin were higher in patients than in healthy donors (p < 0.05). After WMT treatment, the levels of DAO and endotoxin decreased (p < 0.05). CONCLUSIONS WMT is effective for reducing serum uric acid levels and improving gout symptoms in patients with gout and contributes to improve their impaired intestinal barrier function.

Abstract
OBJECTIVE Coronavirus disease 2019 (COVID-19) is often accompanied by gastrointestinal symptoms, which are related to gut microbiota dysbiosis (GMD). Whether washed microbiota transplantation (WMT) is an effective treatment for COVID-19 patients suspected of having GMD by restoring the gut microbiota is unknown. This study is designed to explore the efficacy and safety of WMT in COVID-19 patients suspected of having GMD. METHODS This is a randomized, multicenter, single-blind prospective study. COVID-19 patients suspected of having GMD will be randomly divided to receive routine treatment only or to receive routine treatment and WMT. The frequency of WMT will be once a day for three consecutive days. Laboratory and imaging examinations will be performed at admission, 1 and 2 weeks after treatment, and on the day of discharge. Then a telephone follow-up will be conducted at 1st week, 2nd week, and 6th month after discharge. The clinical efficacy and safety of WMT in COVD-19 patients suspected of having GMD and the effects of WMT on the organ function, homeostasis, inflammatory response, intestinal mucosal barrier function, and immunity of the patients will be evaluated. RESULTS By following the proposed protocol, WMT is expected to be efficacious and safe for the treatment of COVID-19 patients suspected of having GMD, and the therapeutic effect is expected to be associated with improvement of the intestinal mucosal barrier function, inflammatory response, and immunity. CONCLUSION The findings from this study may offer a new approach for the prevention and treatment of COVID-19 patients suspected of having GMD.

Abstract
Although annual mortality trends for prostate cancer were stabilized in recent years, understanding the exact treatment changes is necessary for optimal management. Utilization of not-otherwise specified (NOS) treatments for prostate cancer was unclear. Thus, this study aimed to analyze trends in treatment for prostate cancer in the U.S. from 2010 to 2015 and examine whether the treatment for the prostate cancer in the U.S. is compliant with clinical practice guidelines. Using joinpoint regression models, we examined trends in the rate and proportion of age-standardized utilization (ASUR and ASUP) of treatments for prostate cancer diagnosed during 2010-2015 in the U.S. based on the data from the Surveillance, Epidemiology, and End Results (SEER, 2018 data-release, with linkage to active surveillance/watchful waiting [AS/WW]) cancer registry program. Among 316,690 men with prostate cancer diagnosed during 2010-2015, ASUR and ASUP for radical prostatectomy, radiotherapy, AS/WW and NOS treatment were 32.7, 34.4, 10.0 and 40.1 per 100,000, and 27.9%, 29.3%, 8.5% and 34.2%, respectively. Trends in the overall ASUR for prostate cancer treatments differed by cancer risk group, patients' age, race/ethnicity, Gleason score, insurance status, and the average education level, average poverty-level and foreign-born person percentage of the patient's residence-county, but not by rural-urban continuum or region. ASUP of radical prostatectomy decreased from 9.8% in 2010 to 4.8% in 2015 (annual percent change [APC] = -12.0%, 95% CI, -15.9 to -7.9%), and the decrease was observed in all different risk groups. ASUP of AS/WW increased from 16.4% in 2010 to 30.2% in 2013 (APC = 22.7%, 95% CI, 4.6 to 44.0%) and then remained stable through 2013 to 2015 (APC = 1.9%, 95% CI, -24.1 to 36.9%). The increasing tendency of AS/WW only occurred in the low-risk and intermediate-risk groups. The ASUP of NOS treatment has increased from 32.3% in 2010 to 36.8% in 2015 (P<0.01). In conclusion, ASUR and ASUP for prostate cancer treatments, including NOS treatment, had changed during 2010-2015. Their trends appeared to differ by cancer risk-group, age, race/ethnicity, Gleason score and socioeconomic factors. Future studies are warranted to understand the impacts of upward trends in ASUP of NOS treatments and AS/WW on patient survival and prostate cancer mortality.

Abstract
BACKGROUND The pathogenesis of gastroesophageal reflux disease (GERD) is closely associated with the intestinal bacteria composition and their metabolites.
AIM To investigate whether washed microbiota transplantation (WMT) improves symptoms of nonerosive reflux disease (NERD) with proton pump inhibitor (PPI) dependency.
METHODS Patients with recurrent NERD and PPI dependency at the First Affiliated Hospital of Guangdong Pharmaceutical University from 2017 to 2018 were included and divided into a WMT or PPI group treated with PPI with/without WMT. The endpoint was NERD symptom frequency evaluated 1 mo after WMT using reflux disease questionnaire (RDQ) and GERD questionnaire (GERDQ) scores, remission time, PPI dose, and the examination of intestinal mucosal barrier function.
RESULTS In the WMT (n = 15) and PPI (n = 12) groups, the total remission rate at 1 mo after treatment was 93.3% vs 41.7%. Compared with the PPI group, the WMT group showed better results in GERDQ (P = 0.004) and RDQ (P = 0.003) and in remission months (8 vs 2, P = 0.002). The PPI dose was reduced to some extent for 80% of patients in the WMT group and 33.3% in the PPI group. In 24 patients, intestinal mucosal barrier function was examined before treatment, and changes in the degree of damage were observed in 13 of these patients after treatment. Only one of the 15 patients had minor side effects, including a mushy stool two or three times a day, which resolved on their own after 1 wk.
CONCLUSION This study is the first to demonstrate that WMT may be safe and effective for relieving NERD symptoms and reducing PPI dependency and recurrence.

Abstract
RATIONALE There are many treatments for chronic hemorrhagic radiation colorectal inflammation, but only a few treatments are supported by high-quality research evidence. Studies have shown that the occurrence and development of radiation proctitis are closely associated with the intestinal flora. Animal studies have indicated that faecal microbiota transplantation (FMT) can improve radiation enteropathy in a mouse model. PATIENT CONCERNS A 45-year-old female patient suffered from recurrent hematochezia and diarrhea for half a year after radiotherapy and underwent recurrent transfusion treatments. Colonoscopy showed obvious congestion of the sigmoid colon and rectal mucosa, a smooth surface, and bleeding that was easily induced by touch, which are consistent with radiation proctitis. The pathological findings revealed chronic mucosal inflammation. The magnetic resonance imaging examination of the pelvic cavity with a plain scan and enhancement showed changes after radiotherapy and chemotherapy, and no obvious tumor recurrence or metastasis was found. The laboratory examinations excluded pathogen infection. DIAGNOSES Based on the history and examinations, the final diagnosis of this patient was chronic hemorrhagic radiation proctitis. INTERVENTIONS The patient was treated with a total of 4 individual courses of FMT. OUTCOMES After the six-month follow-up, her hematochezia, abdominal pain and diarrhea were relieved. Furthermore, 16S rRNA sequencing of the feces showed that the intestinal bacterial composition of the patient obviously changed after FMT and became similar to that of the donors. LESSONS This case report shows that FMT can relieve the symptoms of hematochezia and diarrhea by changing the bacterial community structure in patients with chronic hemorrhagic radiation proctitis.

Abstract
Abstract
BACKGROUND: Coronavirus disease 2019 (COVID-19) is often accompanied by gastrointestinal symptoms, which is related to gut microbiota dysbiosis (GMD). Whether washed microbiota transplantation (WMT) is effective in COVID-19 patients suspected with GMD by restoring gut microbiota is unknown. This study is designed to explore the efficacy and safety of WMT in COVID-19 patients suspected with GMD.METHODS: COVID-19 patients suspected with GMD will be randomly divided to receive routine treatment (group A) or receive routine treatment and WMT (group B). The frequency of WMT will be once a day for three consecutive days. Nucleic acid test, imaging examination, and tests related to organ functions, homeostasis, inflammatory response, intestinal barrier function and immunity will be performed at admission, 1, and 2 weeks after treatment and on the day of discharge. The clinical efficacy and safety of WMT in COVD-19 suspected with GMD and the effects of WMT on the organ function, homeostasis, inflammatory response, intestinal barrier function and immunity of the patients will be evaluated. The primary outcome will be the clinical efficacy, as reflected by the SARS-Cov-2 infection status, gastrointestinal symptoms and the recovery of the disease. The secondary outcomes will be the effects of WMT on the organ function, homeostasis, inflammatory response, intestinal barrier function and immunity of the patients, as well as occurrence of adverse events during WMT.DISCUSSION: In the proposed protocol, WMT is expected to be efficacious and safe for the treatment of COVID-19 patients suspected with GMD, and the therapeutic effect is expected to be associated with the improvement of intestinal barrier function, inflammatory response and immunity. Findings from this study may open up a new way for the prevention and treatment of COVID-19 suspected with GMD.TRIAL REGISTRATION: Chinese Clinical Trial Registry – URL: http://www.chictr.org.cn/index.aspx.

Abstract
AbstractSome subtypes of alcoholic liver disease (ALD) recently had increasing prevalence or mortality. Prevalence of alcoholic fatty liver disease was increased. Mortality of alcoholic hepatitis and cirrhosis also had upward trends. However, trends in ALD- mortality and related factors are unclear. We therefore examined trends in age-standardized ALD-mortality among U.S. adults by factors using multivariable piecewise log-linear models. We collected mortality-data (age-standardized for the 2000 U.S. standard population) from the Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research database (CDC WONDER), using the Multiple Cause of Death Data to identify all ALD deaths in the United States for 1999-2017. We identified 296,194 deaths of ALD during 1999-2017. Trends in multivariable-adjusted, age-standardized mortality did not differ by sex, race, age or urbanization. The age-standardized mortality ratios of male/female, White/non-White and Metropolitan/Non-Metropolitan were 2.346, 1.657 and 0.851 in 2017, respectively. Strikingly, our multivariable model showed that subjects of 65+ years had the highest and the fastest growing mortality in the 3 age-groups. These findings highlight the continuation of health disparities in ALD, particularly in elderly subjects. Further works are warranted to validate and delineate the associated factors.

Abstract
AIM The fecal microbiota transplantation by washed preparation was recently coined as washed microbiota transplantation (WMT). This pilot study is aimed at exploring the feasibility and efficacy of WMT on Helicobacter pylori eradication. METHODS Consecutive patients who had been treated with WMT for various indications and who were positive for H. pylori infection before WMT treatment but had never received eradication therapy for H. pylori infection were invited to take a follow-up 13C-urea breath test. The associations of demographic, clinical factors, and laboratory indicators for gastric function and intestinal barrier function with the therapeutic effect were determined. RESULTS A total of 32 eligible patients were included, and the overall H. pylori eradication rate was 40.6% (13/32). Patients with H. pylori eradication had a higher pepsinogen ratio (PGR) than those without (13.00 ± 6.97vs.8.31 ± 3.733; P = 0.02). Female patients had a higher, albeit not statistically significant, eradication rate than male patients (53.85% vs. 31.58%; P = 0.208). Compared with lower gastrointestinal tract delivery route, middle gastrointestinal tract delivery route seems to be a more suitable way for the treatment of H. pylori infection (58.33% vs 16.67%; P = 0.152). There was no significant difference in other demographic and clinical factors between patients with and without H. pylori eradication. CONCLUSION H. pylori infection is eradicated in a proportion of patients who have received WMT. An increased pre-WMT PGR appears to be associated with the therapeutic effect. Further studies are required to confirm the efficacy of WMT, especially in combination with currently recommended regimens in randomized controlled trials.

Abstract
BACKGROUND Alopecia areata is a hair loss disease associated with genetics, autoimmunity, and other factors. There is an intriguing link between alopecia areata and gut dysbiosis. Fecal microbiota transplantation (FMT) has been recommended to treat Clostridium difficile (previously known as Clostridioides difficile) infection, and has also shown potentials in the treatment of inflammatory bowel disease, irritable bowel syndrome, and non-alcohol fatty liver disease.
CASE SUMMARY An 86-year-old man, with a history of sigmoid colon carcinoma, suffered from recurrent abdominal pain and distension, and diarrhea for six months, with inappetence. At admission, he was also diagnosed with depression. Upon physical examination, the patient presented with a 1.5 cm × 2.0 cm alopecia areata on his right occiput. Due to the negative results of laboratory testing, capsule endoscopy, and colonoscopy, the patient was diagnosed with noninfectious diarrhea, depressive disorder, and patchy alopecia areata. Considering that noninfectious diarrhea in the elderly patient was mainly caused by gut dysbiosis, he was given six rounds of FMT. His diarrhea improved remarkably one month after FMT, with improved appetite and disappearance of abdominal pain, distension, and depressive symptoms. Surprisingly, he reported new hair growth on the affected region of his scalp, with some of his white hair gradually turning to black, without taking any other therapies for alopecia areata before and after FMT.
CONCLUSION FMT might act as a potential therapy for patients who suffer from alopecia areata. Large and well-designed studies are required to confirm the role of FMT in alopecia areata.

Abstract
Publications by Chinese researchers in scientific journals have dramatically increased over the past decade; however, academic misconduct also becomes more prevalent in the country. The aim of this prospective study was to understand the perceptions of Chinese biomedical researchers towards academic misconduct and the trend from 2010 to 2015. A questionnaire comprising 10 questions was designed and then validated by ten biomedical researchers in China. In the years 2010 and 2015, respectively, the questionnaire was sent as a survey to biomedical researchers at teaching hospitals, universities, and medical institutes in mainland China. Data were analyzed by the Chi squared test, one-way analysis of variance with the Tukey post hoc test, or Spearman's rank correlation method, where appropriate. The overall response rates in 2010 and 2015 were 4.5% (446/9986) and 5.5% (832/15,127), respectively. Data from 15 participants in 2010 were invalid, and analysis was thus performed for 1263 participants. Among the participants, 54.7% thought that academic misconduct was serious-to-extremely serious, and 71.2% believed that the Chinese authorities paid no or little attention to the academic misconduct. Moreover, 70.2 and 65.2% of participants considered that the punishment for academic misconduct at the authority and institution levels, respectively, was not appropriate or severe enough. Inappropriate authorship and plagiarism were the most common forms of academic misconduct. The most important factor underlying academic misconduct was the academic assessment system, as judged by 50.7% of the participants. Participants estimated that 40.1% (39.8 ± 23.5% in 2010; 40.2 ± 24.5% in 2015) of published scientific articles were associated with some form of academic misconduct. Their perceptions towards academic misconduct had not significantly changed over the 5 years. Reform of the academic assessment system should be the fundamental approach to tackling this problem in China.

Abstract
The purpose of this study was to assess the anti-tumor effects of macrophage migration inhibitory factor (MIF) siRNA on colorectal cancer in a mouse xenograft model. MIF specific siRNA (MIF siRNA) or a nonspecific control siRNA was introduced to murine colorectal cancer CT-26 cells. Mouse xenograft models of colorectal cancer were established. MIF siRNA, control siRNA or water was injected twice a week intravenously for 4 weeks. MIF siRNA inhibited the proliferation and migration, while induced apoptosis of CT-26 cells in vitro. Injection of MIF siRNA resulted in a significant decrease of serum MIF and VEGF levels, and the weight and volume of cecum-grafted tumors in vivo. In contrast, the number of apoptotic cells and caspase-3 expression were increased by MIF siRNA in cecum graft tumor tissues. Moreover, the water and fodder consumption were significantly improved by MIF siRNA treatment. Importantly, MIF siRNA reduced the hepatic metastases from colorectal cancer. Our results suggest that siRNA targeting MIF is a promising agent for the treatment of hepatic metastasis of colorectal cancer cells.

Abstract
BACKGROUND Interleukin (IL)-10 is a pleiotropic cytokine with anti-inflammatory and immunosuppressive properties in liver failure. Biomarkers are urgently needed to predict prognosis of acute-on-chronic hepatitis B liver failure (ACHBLF). AIM To investigate the potential diagnostic value of plasma IL-10 as a biomarker for predicting the mortality of ACHBLF. METHODS This prospective study consisted of 115 newly diagnosed ACHBLF patients from May 2009 to October 2013 as a training cohort and 54 ACHBLF patients from November 2013 to March 2015 as a validating cohort. Plasma IL-10 level was measured using enzyme-linked immunosorbent assay. RESULTS In the training cohort, the plasma IL-10 level of nonsurvivals [median (centile25; centile75): 12.38 (8.76; 15.52) pg/mL] was significantly higher than that in survivals [6.55 (5.43; 7.65) pg/mL, P < 0.001]. Plasma IL-10 (hazard ratio = 1.205, 95% confidence interval: 1.145-1.267, P < 0.001) was identified as an independent risk factor for mortality of ACHBLF patients. Furthermore, plasma IL-10 showed higher area under the curve of receiver operating characteristic (AUROC) than model for end-stage liver diseases (MELD) for predicting 1-month (0.887 vs. 0.779, P < 0.05), 2-month (0.878 vs. 0.779, P < 0.05) and 3-month (0.917 vs. 0.776, P < 0.001) mortality. However, we did not find significant differences in AUROC between IL-10 and IL-10 plus MELD for 1-, 2- and 3-month mortality. ACHBLF patients with plasma IL-10 > 9.6 pg/mL showed poor survival time than patients with plasma IL-10 ≤ 9.6 pg/mL at the end of 1 month in the training and validation cohorts. CONCLUSIONS Plasma IL-10 performed better than MELD in predicting the prognosis of acute-on-chronic hepatitis B liver failure. Furthermore, plasma IL-10 > 9.6 pg/mL predicts a poor 1-month mortality.

Abstract
Background. Endoscopic retrograde cholangiopancreatography (ERCP) is an established treatment modality for bile duct disorders, but patients have a risk of post-ERCP pancreatitis (PEP) and biliary sepsis. Aim. To evaluate the effectiveness and safety of pancreatic stent for prophylaxis of PEP and biliary sepsis in high-risk patients with complicating common bile duct (CBD) disorders. Methods. Two hundred and six patients with complicating confirmed or suspected CBD disorders were randomly assigned to receive ERCP with pancreatic stenting (experimental group) or without stenting (control group). Primary outcome measure was frequency of PEP, and secondary outcome measures included operative time, blood loss, postoperative recovery times, and other ERCP-associated morbidities. Results. Baseline age, sex, CBD etiology, concomitant medical/surgical conditions, cannulation difficulty, and ERCP success were comparable between the two groups (all P > 0.05). Compared to the control group, the experimental group had a significantly lower frequency of PEP (7.7% versus 17.7%, P < 0.05) and positive bile microbial culture (40.4% versus 62.7%, P < 0.05). However, the two groups were similar in operative time, blood loss, postoperative recovery times, and other ERCP-associated morbidities (all P > 0.05). Conclusions. Pancreatic stenting can reduce the occurrence of PEP and biliary sepsis in high-risk patients with complicating CBD disorders but does not increase other ERCP-associated morbidities. This trial is registered with the Chinese Clinical Trial Registry (registration identifier ChiCTR-OCH-14005134).

Abstract
Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of liver dysfunction worldwide, and its prevalence is highly associated with genetic susceptibility. The transmembrane 6 superfamily member 2 (TM6SF2) E167K variant represents a general genetic determinant of hepatic triglyceride content and lobular inflammation, and its presence appears to be directly involved in the pathogenesis and development of NAFLD. Although this variant appears to be a novel powerful modifier in the development of NAFLD, whether it is associated with an increased risk of NAFLD-related liver fibrosis and hepatocellular carcinoma (HCC) remains to be determined. The aim of this review is to describe the functions of the TM6SF2 E167K variant and its association with NAFLD, with particular emphasis on the underlying mechanisms of its role in the development and progression of NAFLD. Additionally, the links between the TM6SF2 E167K variant and NAFLD-related liver fibrosis and HCC will be discussed.

Abstract
The zinc finger protein A20 is a newly identified negative regulator of immune response and mediates signal pathway of NF-κB in liver inflammation. However, the role of A20 in the natural history of patients with chronic hepatitis B (CHB) has not been demonstrated. In this present study, we aimed to investigate the dynamic expression of A20 and determine the potential association of A20 in the progression of chronic hepatitis B virus infection.This retrospective study contained 136 patients with chronic hepatitis B and 30 healthy controls (HCs). The mRNA level of A20, TNF-α, NF-κB p65 and toll-like receptor (TLR) 4 in peripheral blood mononuclear cells (PBMCs) was determined using a relative quantitative real-time polymerase chain reaction. The hepatic A20 protein expression was determined by immunohistochemistry. Clinical and laboratory parameters were obtained.In the present study, the relative expression of A20 mRNA was significantly increased in CHB patients compared with HCs and was positively associated with alanine aminotransferase, aspartate aminotransferase, and total bilirubin. In CHB patients, the levels of A20 mRNA in the immune clearance (IC) phase and hepatitis B negative (ENH) phase were significantly higher than that in immune tolerance (IT) phase and low-replicative (LR) phase (P < 0.001). Furthermore, the A20 mRNA level was significantly correlated with TNF-α/ NF-κB p65/TLR4 mRNA levels in CHB patients. Of note, we reported that cutoff values of 4.19 and 3.97 for the level of A20 mRNA have significant power in discriminating IC from IT, and ENH from LR in CHB patients respectively.In conclusion, our results suggested that increased levels of A20 mRNA and protein contribute to disease progression of chronic hepatitis B virus infection.

Abstract
CONTEXT The PNPLA3 I148M variant has been recognized as a genetic determinant of liver fat content and a genetic risk factor of liver damage progression associated with steatohepatitis. The I148M variant is associated with many chronic liver diseases. However, its potential association with inflammatory and autoimmune liver diseases has not been established. EVIDENCE ACQUISITION We systemically reviewed the potential associations of I148M variant with chronic viral hepatitis, autoimmune liver diseases and the outcome of liver transplantation, explored the underlying molecular mechanisms and tried to translate them into more individualized decision-making and personalized medicine. RESULTS There were associations between I148M variant and chronic viral hepatitis and autoimmune liver diseases and differential associations of I148M variant in donors and recipients with post-liver transplant outcomes. I148M variant may activate the development of steatosis caused by host metabolic disorders in chronic viral hepatitis, but few researches were found to illustrate the mechanisms in autoimmune liver diseases. The peripherally mediated mechanism (via extrahepatic adipose tissue) may play a principal role in triglyceride accumulation regardless of adiponutrin activity in the graft liver. CONCLUSIONS Evidences have shown the associations between I148M variant and mentioned diseases. I148M variant induced steatosis may be involved in the mechanism of chronic viral hepatitis and genetic considered personalized therapies, especially for PSC male patients. It is also crucial to pay attention to this parameter in donor selection and prognosis estimation in liver transplantation.

Abstract
Ascites is the pathologic accumulation of fluid within the peritoneal cavity. Because many diseases can cause ascites, in particular cirrhosis, samples of ascitic fluid are commonly analyzed in order to develop a differential diagnosis. The concept of transudate versus exudate, as determined by total protein measurements, is outdated and the use of serum-ascites albumin gradient as an indicator of portal hypertension is more accurate. Lactate dehydrogenase (LDH), vascular endothelial growth factor (VEGF), and other tumor markers can be helpful in distinguishing between malignant and benign conditions. Glucose and adenosine deaminase levels may support a diagnosis of tuberculous disease, and amylase level may indicate a diagnosis of pancreatitis. Given the specificity and sensitivity of laboratory results, accurate diagnosis should be based on both laboratory data and clinical judgment.

Abstract
AIM To investigate whether losartan has protective effects in mice with chronic viral myocarditis induced by coxsackievirus B3 (CVB3). MAIN METHODS Thirty two male Balb/c mice were intraperitoneally injected with CVB3 (10×TCID50) to induce chronic viral myocarditis (CVM). Losartan at 12.5mg/kg (n=16) or normal saline (n=16) were orally administered daily for 28 days to these mice. Uninfected mice (n=6) were used as controls. On day 29, all mice underwent anesthesia and echocardiography prior to sacrifice. Serum IL-17, IL-4, IFN-γ and TNF-α levels were measured by enzyme-linked immunosorbent assay, and cardiac tissues were histologically examined after hematoxylin & eosin staining. In addition, the effect of losartan on the virus titers in primary cultured neonatal rat cardiomyocytes infected with CVB3 was measured on Hep-2 cells at 72 h post infection. KEY FINDINGS Mice infected with CBV3 had significantly increased mortality, heart/body weight ratios, necrosis and inflammatory scores and decreased cardiac ejection fractions, compared with the controls (all P<0.05). Losartan significantly decreased mortality from 40.0% to 12.5%, heart/body weight ratios from 7.08 ± 2.17 to 4.15 ± 0.99, and necrosis and inflammatory scores from 3.33 ± 0.50 to 2.50 ± 0.65 (all P<0.05), and increased ejection fractions from 55.80 ± 9.25 to 72.31 ± 12.15 (P<0.05). Losartan significantly enhanced IL-4, and decreased IFN-γ, TNF-α and IL-17 (all P<0.05). In the in vitro experiment, losartan had no influence on virus titers. SIGNIFICANCE Losartan protects mice against CVB3-induced CVM, most likely through upregulating Th2 responses, and down-regulating Th1 and Th17 responses.

Abstract
OBJECTIVE Helicobacter pylori infection and overexpression of cyclo-oxygenase-2 (COX-2) are associated with gastric cancer and its precursors. To evaluate the effect of a selective COX-2 inhibitor alone and combined with H pylori eradication on the evolution of precancerous gastric lesions, a randomised, placebo-controlled trial was conducted in Linqu County, Shandong Province, China. METHODS A total of 1024 participants aged 35-64 years with H pylori infection and advanced gastric lesions were randomly assigned in a factorial design to two interventions or placebo: anti-H pylori treatment for 7 days, and a COX-2 inhibitor (celecoxib) for 24 months. The effects of the interventions were evaluated by the regression or progression of advanced gastric lesions. RESULTS Of the 1024 participants who received anti-H pylori treatment or placebo, 919 completed a subsequent 24-month treatment with celecoxib or placebo. The H pylori eradication rate by per-protocol analysis was 78.2%. Compared with placebo, the proportions of regression of gastric lesions significantly increased in the celecoxib treatment (52.8% vs 41.2%) and anti-H pylori treatment (59.3% vs 41.2%) group, and OR by per-protocol analysis was 1.72 (95% CI 1.07 to 2.76) for celecoxib and 2.19 (95% CI 1.32 to 3.64) for H pylori eradication. No statistically significant effect was found for H pylori eradication followed by celecoxib on the regression of advanced gastric lesions (OR 1.48, 95% CI 0.91 to 2.40). CONCLUSION This population-based intervention trial revealed that celecoxib treatment or H pylori eradication alone had beneficial effects on the regression of advanced gastric lesions. No favourable effects were seen for H pylori eradication followed by celecoxib treatment. Trial registration HARECCTR0500053 in accordance with WHO ICTRP requirements.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) is a cause of chronic gastritis and maybe responsible for functional dyspepsia in a subset of patients. Many risk factors, such as alcohol consumption and smoking, may contribute to the colonization and infection of H. pylori in humans. However, studies on the relationship between H. pylori infection and drinking or smoking have produced conflicting results. OBJECTIVE The aim of this study was to examine whether consumption of alcohol or smoking is associated with active H. pylori infection in functional dyspepsia patients. METHODS H. pylori infection was confirmed by CLOtest and histology on at least two biopsies. Active chronic gastritis was diagnosed using the updated Sydney system. In addition to gender and age, information on drinking and smoking habits was collected using a standard questionnaire. Functional dyspepsia was diagnosed according to the Rome II diagnostic criteria. RESULTS H. pylori infection was positive in 27.3% of the 139 functional dyspepsia patients. Both age and gender were not significantly associated with H. pylori infection. A multiple logistic model found that alcohol consumption (OR = 9.05, 95% CI: 1.05-77.98) and pathology (active gastritis) (OR = 595.39, 95% CI: 81.43-4353.33) were associated with H. pylori infection. Active gastritis was associated with alcohol consumption (OR = 2.89, 95% CI: 1.03-8.02), smoking (OR = 2.72, 95% CI: 1.22-6.05) and age (OR = 1.03, 95% CI: 1.01-1.06). CONCLUSIONS In patients with functional dyspepsia, there is no significant association between active H. pylori infection and smoking. However, alcohol consumption appears to be associated with H. pylori infection.

Abstract
PURPOSE To determine the safety and radiation-enhancing effect of sodium glycididazole in laryngeal squamous cell carcinoma (stage T3-4,N0-3,M0) with conventional radiotherapy. PATIENTS AND METHODS Patients with locoregional advanced laryngeal cancer (stage T3-4,N0-3,M0) were included: group 1(control, n=30)were not administered of sodium glycididazole; group 2 (test, n=30) received sodium glycididazole at a dose of 700 mg/m(2) intravenous infusion 30 minutes before radiotherapy three times a week. Surrogate end-points of efficacy were tumor and nodal size. Safety parameters were vomiting, nausea, mucositis, laryngeal edema, esophagus and skin reaction, dysphagia, dyspnea, neurological deficit. Patients were evaluated weekly during treatment for 7 weeks and thereafter monthly for 3 months. RESULTS In the test, the overall response rate was 88.89% (95%CI, 71.00-97.00%) at 7 weeks and 92.59% (95%CI, 76.00 to 99.00%) at 1 month of follow-up. In the control, the overall response rate was 62.5% (95%CI, 41.00 to 81.00%) at 7 weeks and 58.33% (95%CI, 37.00 to 78.00%) at 1 month of follow-up. The short-term locoregional response rate was better in the test group at 7 weeks (p=0.027) and at 1 month (p=0.005) of follow-up. The test group had significantly more nausea and vomiting in weeks 1 (p=0.047), 2 (p=0.007), and 3 (p=0.01) of treatment. CONCLUSIONS The study indicates sodium glycididazole is an effective radiation-enhancing agent that improves short-term locoregional control and is well tolerated in patients with locoregionally advanced laryngeal cancer.

Abstract
BACKGROUND This study aimed to determine the potential diagnostic value of migration-inhibitory factor (MIF) for gastric cancer in patients presenting with dyspepsia and its prognostic value for gastric cancer. METHODS A cohort of 97 patients with histologically confirmed gastric adenocarcinoma and 222 patients with dyspepsia were recruited. Enzyme-linked immunosorbent assay was used to measure serum MIF and carcinoembryonic antigen (CEA). RESULTS The serum MIF concentrations were 6554.0 +/- 204.1 pg/mL and 1453.7 +/- 79.9 pg/mL, respectively, in gastric cancer patients and dyspeptic patients (P < .001). Serum MIF levels increased with the advancing gastric pathologies (P < .001). With the cutoff value of 3230 pg/mL, serum MIF had sensitivity, specificity, and accuracy of 83.5%, 92.3%, and 89.7%, respectively, in diagnosing gastric cancer, whereas the rates were 60.8%, 83.3%, and 76.5%, respectively, for serum CEA. Gastric cancer patients with serum MIF levels above 6600 pg/mL had a lower 5-year survival rate than those with serum MIF level below that level (P = .012). Higher serum CEA levels were also associated with poor survival. The prediction for 5-year survival was even better (P = .0001), using a combination of serum MIF and CEA. CONCLUSIONS Serum MIF level, which correlates with gastric MIF expression, is a better molecular marker than CEA in diagnosing gastric cancer in patients presenting with dyspepsia. A combination of serum MIF and CEA predicts 5-year survival better than the individual test.

Abstract
PURPOSE This study was to determine whether gastric expression of homeoproteins is altered in Helicobacter pylori infection, incisural antralisation, and intestinal metaplasia (IM). METHODS Gastric biopsy specimens were taken from 98 patients with non-ulcer dyspepsia for the detection of H. pylori infection; histological examinations; immunohistochemical staining of CDX2, PDX1, PAX6, and NKX6.1. RESULTS Of the patients, 38 were positive for H. pylori infection, 44 had antral-type mucosa at the incisura, and 22 had IM in the stomach. At the incisura, the expression of PDX1, NKX6.1, and PAX6 in cytoplasm compartment was down-regulated in antral-type mucosa compared with that in the transitional- or body-type mucosa (all P<0.01). The expression of PDX1, PAX6, and NKX6.1 in cytoplasm at the incisura was down-regulated in H. pylori-infected patients compared with that in those without H. pylori infection (all P<0.01). CDX2 expression in whole stomach was up-regulated, but PDX1 expression at the incisura was down-regulated in patients with IM compared with that in those without IM (all P<0.01). CONCLUSIONS Gastric expression of PDX1, PAX 6, and NKX6.1 is down-regulated in H. pylori infection and incisural antralisation. CDX2 is up-regulated but PDX1 is down-regulated in the presence of IM.

Abstract
Macrophage migration inhibitory factor (MIF) is an upstream regulator of immune and inflammatory responses; however, its role in Helicobacter pylori (HP)-associated gastritis remains unknown. We infected MIF knockout (KO) and wild-type mice with SS1 HP and found that 2 weeks after infection, MIF and its receptor CD74 were markedly up-regulated in wild-type mice. This up-regulation preceded the up-regulation of both tumor necrosis factor-alpha and intercellular adhesion molecule-1, as well as the development of moderate gastritis at 8 weeks, as determined by a significant infiltration of neutrophils, T cells, and macrophages. In contrast, KO mice were protected against HP-induced gastritis by preventing the up-regulation of CD74 and Th1-mediated immune injury, including a reduction in the Th1 transcriptional factor T-bet and the expression of interferon-gamma. Additionally, inhibition of skin delayed type hypersensitivity reactions to HP antigens in KO mice also suggested a critical role for MIF in cell-mediated injury. A regulatory role for MIF in Th1-immune responses was further demonstrated by the finding that antigen-primed CD4(+) T cells lacking MIF failed to differentiate into the Th1 phenotype; these cells were instead promoted to Th2 differentiation after challenge with HP antigen in vitro. Results from this study indicated that inhibition of HP-induced innate immune responses and Th1-mediated immune injury may be the key mechanisms by which KO mice failed to develop gastritis after HP infection.

Abstract
BACKGROUND Chest pain is common and data regarding noncardiac chest pain (NCCP) in Asia are lacking. AIM To determine the differences in clinical presentations, psychologic impact, and quality of life between patients with NCCP and cardiac chest pain (CCP), and to identify any factors that impacted on these patients. METHODS Consecutive patients undergoing coronary angiography for the evaluation of chest pain were recruited in Hong Kong and Wuhan, China. One hundred and forty patients with abnormal and 141 patients with normal angiography were included in the study. The validated gastroesophageal reflux disease questionnaire, the Hospital Anxiety-Depression Scale, and the 12-item Short Form Health Survey (SF-12) were used for assessment. RESULTS NCCP patients reported similar days-off work and impairment of their social life compared with those with CCP. No difference was found in the anxiety and depression scores between the 2 groups. NCCP patients with reflux symptoms had higher anxiety score (7.19 vs. 5.74, P=0.044), reported more interruption of their social life (26% vs. 5%, P<0.0001), and had taken more sick leaves (17% vs. 5%, P=0.018) compared with those without gastroesophageal reflux disease. CONCLUSIONS The quality of life and psychologic impact of patients with NCCP were as significant as those with CCP. NCCP patients with reflux symptoms were more anxious and were impaired in their productivity and social life.

Abstract
BACKGROUND The incidence of 'true' re-infection with Helicobacter pylori after successful eradication remains uncertain. AIM To determine the worldwide rates, risk factors and clinical implications of 'true' re-infection of Helicobacter pylori. 'True' re-infection of H. pylori is defined as the situation where tests for H. pylori infection, which were negative for 12 months after eradication, become positive again at a later stage. RESULTS Thirty six studies were identified through a literature search to be able to produce annual rates of 'true' re-infection, and data from 33 original articles were considered reliable and adequate in the further review. Generally, the reported rates varied from 0% to 23.4% in adults and from 1.9% to 9.6% in children. Most studies from developed countries reported rates of less than 1%, whereas relatively higher rates were reported in most of the developing countries. Small sample sizes included in the studies appeared to be associated with increased re-infection rates. Interfamilial transmission is the major cause of re-infection, although iatrogenic re-infection through contaminated endoscopic equipment has been reported. CONCLUSION Helicobacter pylori re-infection is not a concern in a clinical setting, especially in the developed world; however, caution must be exercised in most developing countries.

Abstract
BACKGROUND AND AIM Cyclooxygenase-2 (COX-2) plays an important role in the carcinogenesis of esophageal squamous cell carcinoma (ESCC). However, it is not clear whether COX-2 is involved in the early or late stage of the development of ESCC. The aim of this study was to investigate the role of COX-2 in the carcinogenesis of ESCC by an immortalized esophageal epithelial cell line. METHODS Human papillomavirus type 16 (HPV16)-E6/E7 and human telomerase reverse transcriptase (hTERT) transfection were used for immortalization of esophageal epithelial cells. COX-2-specific RNA interference was used for the inhibition of COX-2 expression. RESULTS An immortalized esophageal epithelial cell line, NE6-E6E7/hTERT, was established, which had high proliferation activity but failed to induce colony formation in soft agar. COX-2 expression was upregulated in the early process of immortalization, while COX-2 small interfering RNA (siRNA) decreased the Bcl-2 expression, increased the expression of Bax, and induced cell-cycle arrest at the G0/G1 phase in NE6-E6E7/hTERT cells. Expressions of p53, cyclinD1, and the ratio of hyperphosphorylated-RB/hypophosphorylated-RB were progressively increased after E6E7 and the subsequent hTERT transfections. These changes were accompanied by the alteration of COX-2 expression, but could be reversed by COX-2 siRNA (P < 0.05). P16 expression was significantly downregulated in NE6-E6E7 or NE6-E6E7/hTERT cells (P < 0.05), and was not affected by COX-2 siRNA. CONCLUSIONS Our results suggest that induction of cyclooxygenase-2 is essential in the human papillomavirus type 16 and hTERT-induced immortalization of human esophageal epithelial cells, and that COX-2 inhibition may be a potential target to block the carcinogenesis of ESCC at the precancerous stage.

Abstract
AIM To evaluate the long-term risk of gastroduodenal ulcer and cardiovascular events induced by celecoxib in a population-based, randomized, double-blind, placebo-controlled study. METHODS From 2004 to 2006, a total of 1024 Chinese patients (aged 35 to 64 years) with severe chronic atrophic gastritis, intestinal metaplasia or dysplasia were randomly assigned to receive 200 mg of celecoxib twice daily or placebo in Linqu County (Shandong Province, China), a high-risk area of gastric cancer. All gastroduodenal ulcer and cardiovascular events occurred were recorded and the patients were followed up for 1.5 years after treatment. At the end of the trial, a systematic interview survey about other adverse events was conducted. RESULTS Gastroduodenal ulcer was detected in 19 of 463 (3.72%) patients who received celecoxib and 17 of 473 (3.31%) patients who received placebo, respectively (odds ratio = 1.13, 95% CI = 0.58-2.19). Cardiovascular (CV) events occurred in 4 patients who received celecoxib and in 5 patients who received placebo, respectively. Compared with those who received placebo, patients who received celecoxib had no significant increase in occurrence of CV events (hazard ratio = 0.84, 95% CI = 0.23-3.15). Among the adverse events acquired by interview survey, only the frequency of bloating was significantly higher in patients treated with celecoxib than in those treated with placebo. CONCLUSION Treatment of gastric cancer with celecoxib is not associated with increased risk of gastroduodenal ulcer and cardiovascular events.

Abstract
AIM Pancreatic duodenal homeobox-1 (PDX1) is a transcription factor of homeobox genes family important in differentiation and development of the pancreas, duodenum and antrum. This study aims to clarify the putative role of PDX1 in gastric carcinogenesis. METHODS PDX1 expression was detected in gastric tissues with chronic gastritis and cancer as well as gastric cancer cell lines by immunohistochemistry, western blot, reverse transcription-polymerase chain reaction (RT-PCR) or quantitative real-time RT-PCR assays. The effects of PDX1 on cell proliferation, apoptosis, clone formation and migration were evaluated using cancer cell lines after transient or stable transfection with PDX1-expressing vector. The ability of PDX1 stable transfectant in tumor formation in xenograft mice was assessed. RESULTS PDX1 was strongly expressed in normal gastric glands, but was absent in 29 of 39 of human gastric cancer and most gastric cancer cell lines. Negative correlation between PDX1 and Ki-67 expression was found in both gastric tissues and cell lines. Ectopic overexpression of PDX1 significantly inhibited cell proliferation and induced apoptosis, accompanied by the activation of caspases 3, 8, 9 and 10. Overexpression of PDX1 also impaired the ability of cancer cells in clonal formation and migration in vitro. Furthermore, stable transfection with PDX1 reduced the ability of cancer cells in tumor formation in nude mice. CONCLUSIONS PDX1 expression is lost in gastric cancers. Its effect on cell proliferation/apoptosis, migration and tumor formation in vitro and in vivo suggested that this protein functions as a putative tumor suppressor in gastric cancer.

Abstract
XIAP-associated factor 1 (XAF1) is a novel tumor suppressor and interferon stimulated gene (ISG). Interferon beta (IFNbeta) exerts anti-proliferative effect and induces apoptosis through the Jak-Stat signaling cascade by the type I Interferon receptor (IFN-R), which initiates gene transcription of those biological effectors of IFNbeta. The aim of this study is to determine the effect of IFNbeta on XAF1 expression and the putative mechanisms mediated by the critical role of signal transducers and activators of transcription 1 (Stat1). Gene expression was detected by RT-PCR and Western blot analysis. The promoter activity of XAF1 was examined by luciferase reporter assay. The activity of interferon stimulated response element (ISRE) was assessed by electrophoretic mobility shift assay (EMSA) and quantitative chromatin immunoprecipitation assay (Q-ChIP). Results showed that IFNbeta stimulated XAF1 promoter activity in colon cancer cell line DLD1 in a time- and dose-dependent manner. A high affinity ISRE binding element (ISRE-XAF1) was located in -55 to -66 nt upstream of the first ATG site of XAF1 gene. Deletion of ISRE-XAF1 completely abrogated basal and IFNbeta-induced promoter activity. IFNbeta-induced XAF1 expression was mediated by Stat1 through the interaction with ISRE-XAF1. Knocking down of the Stat1 expression and blocking its phosphorylation decreased IFNbeta-induced XAF1 expression. Results suggested that induction of an immediate early response gene-XAF1 by IFNbeta was mediated by the transcription regulator Stat1 through the ISRE site within the promoter region of XAF1 gene in colon cancer.
