Abstract
The challenges in the treatment of extensive bone defects are infection control and bone regeneration. Bone tissue engineering is currently one of the most promising strategies. In this study, a short biopeptide with specific osteogenic ability is designed by fusion peptide technology and encapsulated with chitosan-modified poly(lactic acid-glycolic acid) (PLGA) microspheres. The fusion peptide (FP) mainly consists of an osteogenic functional sequence (P-15) and a bone-specific binding sequence (Asp-6), which can regulate bone formation accurately and efficiently. Chitosan-modified PLGA with antimicrobial and pro-healing effects is used to achieve the sustained release of fusion peptides. In the early stage, the antimicrobial and soft tissue healing effects can stop the wound infection as soon as possible, which is relevant for the subsequent bone regeneration process. Our data show that CS-PLGA@FP microspheres have antibacterial and pro-cell migration effects in vitro and excellent pro-wound-healing effects in vivo. In addition, CS-PLGA@FP microspheres promote the expression of osteogenic-related factors and show excellent bone regeneration in a rat defect model. Therefore, CS-PLGA@FP microspheres are an efficient biomaterial that can accelerate the recovery of bone defects.

Abstract
BACKGROUND & AIMS Previous studies confirm vonoprazan-amoxicillin effectiveness for Helicobacter pylori. This study aims to investigate vonoprazan with varying amoxicillin dose and duration. METHODS This multicenter, prospective, randomized controlled, noninferiority trial enrolled patients with treatment naive H pylori infection from 5 clinical centers. Eligible participants were randomly assigned to H-VA-10 (vonoprazan 20 mg twice a day (b.i.d.) + amoxicillin 750 mg 4 times a day, 10 days), L-VA-10 (vonoprazan 20 mg b.i.d. + amoxicillin 1000 mg b.i.d, 10 days), and H-VA-14 (vonoprazan 20 mg b.i.d + amoxicillin 750 mg 4 times a day, 14 days) in a 1:1:1 ratio. The eradication rate was assessed using the 13C-urea breath test at least 28 days after treatment. RESULTS Of the 623 eligible patients, 516 patients were randomized. In both the intention-to-treat and per-protocol analyses, eradication rates were comparable between H-VA-10 and H-VA-14 groups (86.6% vs 89.5% and 90.9% vs 94.5%, P = .021 and .013 for noninferiority, respectively). However, eradication rates were significantly lower in the L-VA-10 group than the H-VA-14 group (79.7% vs 89.5% and 82.0% vs 94.5%, P = .488 and .759, respectively). Rates of study withdrawal, loss to follow-up, and adverse events were similar across study groups. CONCLUSIONS H-VA-10 and H-VA-14 regimens provide satisfactory efficacy for H pylori infection, and the L-VA-10 regimen was inferior. CLINICALTRIALS gov number: NCT05719831.

Abstract
Oral squamous cell carcinoma (OSCC), as a common type of oral malignancy, has an unclear pathogenesis. N6 methyladenosine (m6 A) is a reversible and dynamic process that participates in the modulation of cancer pathogenesis and development. As an m6 A recognition protein (reader), heterogeneous nuclear ribonucleoproteins A2/B1 (HNRNPA2B1) show abnormally high expression in cancers. Forkhead box Q1 (FOXQ1), an oncogenic transcription factor, controls multiple biological processes (e.g., embryonic development, cell differentiation, and apoptosis, impacting the initiation and progression of cancers by mediating signaling pathways together with epithelial-mesenchymal transition). Through the Cancer Genome Atlas database screening along with clinical and laboratory experiments, in head and neck squamous cell carcinoma, we found a correlation between HNRNPA2B1 and FOXQ1 gene expression, with shared m6 A motifs between HNRNPA2B1 and FOXQ1 mRNA sequences. Silencing or overexpression of HNRNPA2B1 in OSCC cells affected the malignant phenotypes of OSCC cells in vitro, and depletion of HNRNPA2B1 retarded tumor growth in vivo. HNRNPA2B1 could bind to m6 A-modified FOXQ1 mRNA to enhance its mRNA stability, resulting in up-regulation of FOXQ1 protein expression. To conclude, HNRNPA2B1 was upregulated in OSCC and enhanced OSCC cell malignant phenotypes by stabilizing m6 A-modified FOXQ1 mRNA, eventually aggravating the malignancy and tumorigenicity of OSCC. This study accelerates the recognition of the potency of m6 A modification in OSCC and paves the path for OSCC's targeted diagnosis and therapy.

Abstract
Background/Aims The accuracy of endosonographers in diagnosing gastric subepithelial lesions (SELs) using endoscopic ultrasonography (EUS) is influenced by experience and subjectivity. Artificial intelligence (AI) has achieved remarkable development in this field. This study aimed to develop an AI-based EUS diagnostic model for the diagnosis of SELs, and evaluated its efficacy with external validation. Methods We developed the EUS-AI model with ResNeSt50 using EUS images from two hospitals to predict the histopathology of the gastric SELs originating from muscularis propria. The diagnostic performance of the model was also validated using EUS images obtained from four other hospitals. Results A total of 2,057 images from 367 patients (375 SELs) were chosen to build the models, and 914 images from 106 patients (108 SELs) were chosen for external validation. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the model for differentiating gastrointestinal stromal tumors (GISTs) and non-GISTs in the external validation sets by images were 82.01%, 68.22%, 86.77%, 59.86%, and 78.12%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in the external validation set by tumors were 83.75%, 71.43%, 89.33%, 60.61%, and 80.56%, respectively. The EUS-AI model showed better performance (especially specificity) than some endosonographers. The model helped improve the sensitivity, specificity, and accuracy of certain endosonographers. Conclusions We developed an EUS-AI model to classify gastric SELs originating from muscularis propria into GISTs and non-GISTs with good accuracy. The model may help improve the diagnostic performance of endosonographers. Further work is required to develop a multi-modal EUS-AI system.

Abstract
The eradication rate of Helicobacter pylori (H. pylori) decreased gradually. This study aimed to analyze the efficacy and safety of a 14-day combination of vonoprazan and amoxicillin as the first-line eradication therapy for H. pylori infection and compared them with those of the bismuth quadruple therapy. A prospective randomized clinical trial (RCT) was designed, involving patients with H. pylori infection in 6 institutions who did not receive any treatment yet. They were randomly assigned into the VA-dual group (vonoprazan 20 mg b.i.d + amoxicillin 750 mg q.i.d) or EACP-quadruple group (esomeprazole 20 mg + amoxicillin 1000 mg + clarithromycin 500 mg + colloidal bismuth subcitrate 220 mg b.i.d) for 14 days in a ratio of 1:1. At least 28 days later, the eradication rate was detected by the 13C-urea breath test (UBT). A total of 562 patients from February 2022 to September 2022 were enrolled and 316 were random. In the ITT analysis, the eradication rates of H. pylori in the VA-dual group and EACP-quadruple group were 89.9% and 81.0%, respectively, p = 0.037. In the PP analysis were 97.9% and 90.8%, p = 0.009. The different eradication rate was 8.9% (95% CI 1.2-16.5%) and 7.2% (95% CI 1.8-12.4%) in ITT and PP analyses, both lower limit of the 95%CI was still higher than the prespecified margin. In addition, the incidence of adverse events in the VA-dual group was significantly lower than that in the EACP-quadruple group (19.0% vs. 43.0%, P < 0.001). The efficacy and safety of a 14-day combination therapy of vonoprazan and amoxicillin in eradicating H. pylori are superior to bismuth quadruple therapy, and this combination significantly reduces the use of antibiotics.

Abstract
The affordances of social media, have significantly transformed how patients seek and process health information online, including those with chronic diseases like irritable bowel disease (IBD). Few studies have explored how information processing may impact symptom management. Guided by social cognitive theory, this study investigates how Chinese and U.S. patients (N = 838) process health information in a cross-cultural setting and the impact on symptom management. It finds that efficient information processing improves treatment understanding and symptom management for IBD patients, regardless of their cultural backgrounds. It also reveals a U-shaped quadratic relationship between IBD severity and emotional and peer support, indicating varying support needs at different IBD stages. These findings provide valuable insights for healthcare professionals, patients, and caregivers in designing interventions for chronic diseases. The study underscores the importance of recognizing the dynamics of health information processing and the need for a more nuanced approach to patient support and care.

Abstract
OBJECTIVES Ustekinumab (UST) optimization strategies, including shortening intervals and intravenous reinduction, should be administered to patients with partial or loss of respond. Evidence comparing these types of optimization treatments is limited. We evaluated the efficacy and safety of weight-based UST intravenous reinduction in patients with refractory Crohn's disease (CD). METHODS This was a single-center retrospective observational study. Optimization strategies were designed for patients showing partial or loss of response to standardized UST therapy. Clinical, biochemical, and endoscopic response and remission rate were determined by Crohn's disease activity index (CDAI), C-reactive protein (CRP) levels, and SES-CD evaluation. UST trough concentrations were detected and adverse events were recorded. RESULTS A total of 128 patients receiving UST optimization therapies were included, with 105 patients administered shortening intervals of q8w or q4w, and 23 receiving intravenous reinduction followed by subcutaneous q8w or q4w. The follow-up duration for the shortening interval and reinduction cohorts were 15.0 (10.0, 31.0) and 23.0 (13.0, 70.0) weeks, respectively. A significant CDAI delta variation pre-and post-treatment could be found between groups [17.0 (-4.4, 65.9) vs. 69.0(10.7, 151.0), p = 0.013]. the trough concentration of UST increased [2.5 (1.3, 5.3) vs. 1.1 (0.5, 2.3), p = 0.001] after intravenous reinduction. Clinical and endoscopic remission were achieved in 69.6 and 31.8% of patients in the intravenous reinduction cohort, and 62.9 and 22.2% of patients in the shortening interval cohort, respectively. No significant difference was found between groups regarding safety. CONCLUSION Intravenous reinduction brought about favorable recapture of clinical and endoscopic remission, and should have significant priority over the strategy of merely shortening drug intervals, which should be launched before switching to other biologics targeting different inflammatory pathways.Clinical Trial Registration: identifier NCT04923100. https://classic.clinicaltrials.gov/ct2/show/NCT04923100?id=04923100&draw=2&rank=1.

Abstract
Background Previous studies have identified useful endoscopic ultrasonography (EUS) features to predict the malignant potential of gastrointestinal stromal tumors (GISTs). However, the results of the studies were not consistent. Artificial intelligence (AI) has shown promising results in medicine. Objectives We aimed to build a risk stratification EUS-AI model to predict the malignancy potential of GISTs. Design This was a retrospective study with external validation. Methods We developed two models using EUS images from two hospitals to predict the GIST risk category. Model 1 was the four-category risk EUS-AI model, and Model 2 was the two-category risk EUS-AI model. The diagnostic performance of the models was validated with external cohorts. Results A total of 1320 images (880 were very low-risk, 269 were low-risk, 68 were intermediate-risk, and 103 were high-risk) were finally chosen for building the models and test sets, and a total of 656 images (211 were very low-risk, 266 were low-risk, 88 were intermediate-risk, and 91 were high-risk) were chosen for external validation. The overall accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for the four-category risk EUS-AI model in the external validation sets by tumor were 74.50%, 55.00%, 79.05%, 53.49%, and 81.63%, respectively. The accuracy, sensitivity, specificity, PPV, and NPV for the two-category risk EUS-AI model for the prediction of very low-risk GISTs in the external validation sets by tumor were 86.25%, 94.44%, 79.55%, 79.07%, and 94.59%, respectively. Conclusion We developed a EUS-AI model for the risk stratification of GISTs with promising results, which may complement current clinical practice in the management of GISTs. Registration The study has been registered in the Chinese Clinical Trial Registry (No. ChiCTR2100051191).

Abstract
Background The ulcerative colitis (UC) Mayo endoscopy score is a useful tool for evaluating the severity of UC in patients in clinical practice. Objectives We aimed to develop and validate a deep learning-based approach to automatically predict the Mayo endoscopic score using UC endoscopic images. Design A multicenter, diagnostic retrospective study. Methods We collected 15120 colonoscopy images of 768 UC patients from two hospitals in China and developed a deep model based on a vision transformer named the UC-former. The performance of the UC-former was compared with that of six endoscopists on the internal test set. Furthermore, multicenter validation from three hospitals was also carried out to evaluate UC-former's generalization performance. Results On the internal test set, the areas under the curve of Mayo 0, Mayo 1, Mayo 2, and Mayo 3 achieved by the UC-former were 0.998, 0.984, 0.973, and 0.990, respectively. The accuracy (ACC) achieved by the UC-former was 90.8%, which is higher than that achieved by the best senior endoscopist. For three multicenter external validations, the ACC was 82.4%, 85.0%, and 83.6%, respectively. Conclusions The developed UC-former could achieve high ACC, fidelity, and stability to evaluate the severity of UC, which may provide potential application in clinical practice. Registration This clinical trial was registered at the ClinicalTrials.gov (trial registration number: NCT05336773).

Abstract
INTRODUCTION Ustekinumab serves as an important alternative option for patients with various extraintestinal manifestations (EIMs), which leads to poor quality of life and heavy burden of care. Therefore, a comprehensive review summarizing the efficacy and safety of ustekinumab in patients with CDassociated EIMs is needed to provide reference for clinical medication and help with the appliance of precision medicine. AREAS COVERED In this review, we collected and summarized the efficacy and paradoxical side effects of ustekinumab in patients with CDassociated EIMs including musculoskeletal, cutaneous, ocular, and hepatobiliary manifestations. This literature review was performed using PubMed to identify and collect relevant studies published in English. EXPERT OPINION The effectiveness of ustekinumab on patients with CDassociated EIMs is mainly reflected in musculoskeletal and cutaneous manifestations compared to ocular or hepatobiliary manifestations. Relevant data from large scale cohort studies and prospective randomized trials are needed to further demonstrate the efficacy and safety of ustekinumab in patients with multiple EIMs.

Abstract
Inflammatory bowel disease (IBD) is a group of chronic non-specific intestinal inflammatory diseases whose etiology has not been elucidated. The prevalence of elderly-onset IBD is increasing; however, its disease phenotype, pathophysiology, and clinical characteristics are different from those of adult-onset IBD. In order to better manage elderly IBD patients, it is becoming increasingly important to accurately describe the unique characteristics of elderly-onset IBD. Therefore, this article, based on the domestic and foreign literature reports from 2017 to now, describes the characteristics of elderly-onset IBD with regard to pathogenesis, epidemiological characteristics, clinical features, and treatment.

Abstract
Abstract
Background
The eradication rate of Helicobacter pylori (H. pylori) decreased gradually. This study aimed to analyze the efficacy and safety of a 14-day combination of vonoprazan and amoxicillin as the first-line eradication therapy for H. pylori infection, and compared them with those of the bismuth quadruple therapy.
Methods
A prospective randomized clinical trial (RCT) was designed, involving patients with H. pylori infection in 6 institutions who did not receive any treatment yet. They were randomly assigned into VA-dual group (vonprazan 20mg b.i.d + amoxicillin 750mg q.i.d) or EACP-quadruple group (esomeprazole 20mg + amoxicillin 1000mg + clarithromycin 500mg + colloidal bismuth subcitrate 220mg b.i.d) for 14 days in ratio of 1:1. At least 28 days later, the eradication rate were detected by the 13C-urea breath test (UBT).
Results
A total of 562 patients from February 2022 to September 2022 were enrolled and 316 were randomly. In the ITT analysis, the eradication rates of H. pylori in VA-dual group and EACP-quadruple group were 89.9% and 81.0% respectively, p = 0.037. In the PP analysis were 97.9% and 90.8%, p = 0.009. The different eradication rate was 8.9% (95%CI, 1.2–16.5%) and 7.2% (95%CI, 1.8–12.4%) in ITT and PP analysis, both lower limit of the 95%CI was still higher than the prespecified margin. In addition, the incidence of adverse events in VA-dual group was significantly lower than that in EACP-quadruple group (19.0% vs. 43.0%, P < 0.001).
Conclusion
The efficacy and safety of a 14-day combination therapy of vonoprazan and amoxicillin in eradicating H. pylori are superior to bismuth quadruple therapy, and this combination significantly reduces the use of antibiotics.

Abstract
BACKGROUND Crohn's disease (CD), often occurring in women of child-bearing age, can decline the fertility rate. However, whether it reduces ovarian reserve has been rarely reported. This study aimed to evaluate the ovarian reserve in women with CD from the perspective of anti-Müllerian hormone (AMH), and explore the factors that can decrease ovarian reserve. METHODS A case-control retrospective study was designed. We analyzed the AMH levels in a total of 135 CD women and 878 healthy controls. Through propensity score matching, the subjects were assigned in a ratio of 1:3 to CD group (n = 121) and control group (n = 324). Both groups shared similar basic characteristics, like age, body mass index and smoking status. Serum AMH levels were measured by chemiluminescence. RESULTS The AMH level in the CD group was significantly lower than that in the control group (2.17 ± 2.23 μg/L vs 3.95 ± 2.01 μg/L, 95%CI [1.34-2.21], P < 0.001). In both groups, the AMH levels decreased as age increased, but without between-group difference in the decreasing rate (P = 0.639). Multivariate analysis showed that age > 30 years (OR, 2.905; 95%CI [1.053-8.531], P = 0.017), disease activity (OR,4.314; 95%CI [1.561-12.910], P = 0.002) and thalidomide use (OR,12.628; 95%CI [4.351 -42.820], P < 0.001) were independent risk factors associated with decreased ovarian reserve (AMH<1.1μg/L). CONCLUSION Ovarian reserve is lower in CD women than in healthy women. Age, CD activity and medication of thalidomide are risk factors that can aggravate the decline of ovarian reserve.

Abstract
BACKGROUND AND AIMS Gastrointestinal T-cell and NK/T-cell lymphomas are relatively rare and may be difficult to diagnose. Therefore, we performed a retrospective study of the clinical, endoscopic and pathological characteristics of these lymphomas, to provide additional data on this issue. METHODS From April 2013 to April 2021, consecutive patients diagnosed with primary gastrointestinal T-cell and NK/T-cell lymphomas were retrospectively reviewed. Their medical histories, laboratory, imaging, endoscopic, and pathology results were analyzed. RESULTS Forty-two patients were finally chosen, among whom, 24 patients had ENKTCL, 9 patients had MEITL, 2 patients had ALCL, ALK-, 1 patient had ALCL, ALK+, and 6 patients had PTCL, NOS. The median age of all the patients was 48 years old, and 73.81% (31 patients) were male. The patients' symptoms were abdominal pain, diarrhea, gastrointestinal bleeding, weight loss, fever, and others. The endoscopic results of 26 patients could be traced, and 69.23% of the patients showed multiple lesions. Ulcerative and ulceroinfiltrative lesions were common. Among the pathologic findings, necrosis, ulceration, and crypt atrophy were commonly found while epitheliotropism was relatively less common. Twelve patients (28.57%) had a history of misdiagnosis. After a median follow-up time of 26.9 months, 26 patients (66.70%) died of the disease. The median overall survival time was 8 months. CONCLUSIONS These lymphomas had nonspecific clinical manifestations, various endoscopic features, and were likely to be misdiagnosed as other diseases. The prognosis is still poor, and more in-depth research is needed to develop more precise treatments.

Abstract
PURPOSE Models for predicting perforation during endoscopic resection (ER) of gastric submucosal tumors (SMTs) originating from the muscularis propria (MP) are rare. Therefore, this study was conducted to determine important parameters in endoscopic ultrasonography (EUS) images to predict perforation and to build predictive models. METHODS Consecutive patients with gastric SMTs originating from the MP who received ER from May 1, 2013 to January 15, 2021 were retrospectively reviewed. They were classified into case and control groups based on the presence of perforation. Logistic multivariate analysis was used to identify potential variables and build predictive models (models 1 and 2: with and without information on tumor pathology, respectively). RESULTS In total, 199 EUS procedures (194 patients) were finally chosen, with 99 procedures in the case group and 100 in the control group. The ratio of the inner distance to the outer distance (I/O ratio) was significantly larger in the case group than in the control group (median ratio, 2.20 vs. 1.53; P<0.001). Multivariate analysis showed that age (odds ratio [OR], 1.036 in model 1; OR, 1.046 in model 2), the I/O ratio (OR, 2.731 in model 1; OR, 2.372 in model 2), and the pathology of the tumors (OR, 10.977 for gastrointestinal stromal tumors; OR, 15.051 for others in model 1) were risk factors for perforation. The two models to predict perforation had areas under the curve of 0.836 (model 1) and 0.755 (model 2). CONCLUSION EUS was useful in predicting perforation in ER for gastric SMTs originating from the MP. Two predictive models were developed.

Abstract
Background Thalidomide is applied in therapy for refractory Crohn's disease (CD) in adults, but systematic and rigorous clinical evidence is scant. The aim was to provide theoretical references for the efficacy of thalidomide in the therapy for refractory CD in adults. Methods A double-center, double-blind, placebo-controlled, randomized clinical trial of refractory CD in adults in two inflammatory bowel disease centers in China. In the double-blind trial, patients were randomly assigned to 100 mg of thalidomide or placebo daily for 8 weeks. The primary outcome was considered as the clinical remission rate calculated based on the Crohn's disease activity index at the eighth week following thalidomide or placebo treatment. In open label, non-response to placebo was additionally treated with 8 weeks of thalidomide; all responders were continuously treated with thalidomide until the 48th week. Results Twenty-five patients were randomly assigned to each group. At the eighth week, the clinical remission rate in the thalidomide group was significantly higher than that in the placebo group (68.0% [17/25] vs 16.0% [4/25]; relative risk, 4.2; 95% confidence interval, 1.8-10.9, P < 0.001). After a 48-week follow-up, the continuous treatment rate of thalidomide was 46.3% (19/41). Adverse events during the whole process were reported in 58.5% of patients, mainly involving drowsiness, rash, and peripheral neuropathy that were mild and tolerable. Conclusion Thalidomide can be used in the induction and maintenance therapy of refractory CD in adults. And it could be one of the treatment options for refractory CD.

Abstract
BACKGROUND AND AIMS The human gut is home to a largely underexplored microbiome component, the archaeome. Little is known of the impact of geography, urbanization, ethnicity, and diet on the gut archaeome in association with host health. We aim to delineate the variation of the human gut archaeome in healthy individuals and its association with environmental factors and host homeostasis. METHODS Using metagenomic sequencing, we characterized the fecal archaeomes of 792 healthy adult subjects from 5 regions in China, spanning 6 ethnicities (Han, Zang, Miao, Bai, Dai, and Hani), consisting of both urban and rural residents for each ethnicity. In addition, we sampled 119 host variables (including lifestyle, diet, and blood parameters) and interrogated the influences of those factors, individually and combined, on gut archaeome variations. RESULTS Population geography had the strongest impact on the gut archaeome composition, followed by urbanization, dietary habit, and ethnicity. Overall, the metadata had a cumulative effect size of 11.0% on gut archaeome variation. Urbanization decreased both the α-diversity (intrinsic microbial diversity) and the β-diversity (inter-individual dissimilarities) of the gut archaeome, and the archaea-to-bacteria ratios in feces, whereas rural residents were enriched for Methanobrevibacter smithii in feces. Consumption of buttered milk tea (a characteristic diet of the rural Zang population) was associated with increased abundance of M. smithii. M. smithii was at the central hub of archaeal-bacterial interactions in the gut microecology, where it was positively correlated with the abundances of a multitude of short chain fatty acid (SCFA)-producing bacteria (including Roseburia faecis, Collinsella aerofaciens, and Prevotella copri). Moreover, a decreased abundance of M. smithii was associated with increased human blood levels of cholinesterase in the urban population, coinciding with the increasing prevalence of noncommunicable diseases (such as dementia) during urbanization. CONCLUSIONS Our data highlight marked contributions of environmental and host factors (geography, urbanization, ethnicity, and habitual diets) to gut archaeome variations across healthy individuals, and underscore the impact of urbanization on the gut archaeome in association with host health in modern society.

Abstract
Prior studies reported inconsistent results on the altered gut microbial composition in patients with Crohn’s disease (CD), likely under the influences of many confounding factors including genetic, life style and environmental variations among different study cohorts. This study aims to examine the gut microbiota of CD patients with particular efforts to minimize the impact of the confounding factors. For this purpose, the healthy relatives of the patients were enrolled as control subjects so that the paired study subjects may have similar genetic background, dietary habits, and household environment. The fecal microbiota of the study subjects were examined by 16S rRNA sequencing. After the identification of the differential bacterial genera, multivariate regression analysis was performed to adjust the results for the impact of confounding factors. We found that the microbiota of the CD patients were featured with reduced short chain fatty acid (SCFA) producing bacteria and elevated opportunistic pathogen Escherichia-Shigella. Correlation analysis indicated that the elevation in Escherichia-Shigella and the reduction in SCFA-producing bacteria usually occur simultaneously. These differential genera exhibited a high capacity in distinguishing between CD and healthy controls achieving an area under curve of 0.89, and were correlated with the changes in inflammation related blood biochemical markers. Consistent with the reduction in SCFA-producing bacteria in CD, metabolomics analysis revealed decreased blood level of SCFAs in the patients. The differential genera identified in this study demonstrated outstanding capability to serve as diagnosis markers for CD and are potential targets for intervention.

Abstract
Guided bone regeneration (GBR) is a promising strategy for repairing bone defects using bioactive membranes. In this study, a new type of GBR membrane based on the small intestinal submucosa (SIS) was created, and its surface structure, cytological characteristics, and bone defect repair ability were compared with commonly used membranes. Our results show that compared to the Heal-all and Dentium membranes, the SIS membrane has an asymmetric structure that does not affect the proliferation of bone marrow mesenchymal stem cells (BMSCs). Instead, it increased their formation of calcium nodules and expression of bone morphogenetic protein-2 (BMP-2), alkaline phosphatase (ALP), runt-related transcription factor 2 (Runx2), and osteopontin (OPN). Six weeks after their insertion into a rat calvarial defect model, increased bone growth was observed in the SIS membrane group. Our results indicate that the SIS membrane has good biocompatibility and is more effective in promoting early bone formation than existing membranes. Given the wide range of source materials and simple preparation processes available, SIS membrane is a promising candidate for guided bone regeneration.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is rising in China, and the tendency for lifelong recurrence decreases patients' quality of life. However, no studies on treatment decision-making in Chinese patients with IBD exist. Thus, this study aimed to determine the actual and ideal decision-making, as well as factors affecting decision-making in Chinese IBD patients. METHODS A multicenter online questionnaire was distributed among patients diagnosed with IBD. To assess factors that influence treatment decision-making, univariate and multivariate logistic regression analyses were performed. RESULTS From March 20, 2018, to May 20, 2018, a total of 866 patients completed the questionnaires, including 222 patients with ulcerative colitis, 588 patients with Crohn's disease, and 56 patients with unclassified IBD. There was a significant difference between ideal and actual decision-making in Chinese IBD patients (P < .005). The factors affecting ideal decision-making included income, education, illness severity, religiosity, the importance of the treatment decision, the employment situation, and occupation area. The factors affecting actual decision-making included age, illness severity, religiosity, the employment situation, economic anxiety, concern about the side effects, and the importance of the treatment decision. CONCLUSIONS There is a significant difference between ideal and actual decision-making in IBD patients in China. That is, the economy, religiosity, illness severity, and concern about the side effects of treatment are the most important factors affecting treatment decisions in Chinese IBD patients.

Abstract
Background and Aims With the development of artificial intelligence (AI), we have become capable of applying real-time computer-aided detection (CAD) in clinical practice. Our aim is to develop an AI-based CAD-N and optimize its diagnostic performance with narrow-band imaging (NBI) images. Methods We developed the CAD-N model with ResNeSt using NBI images for real-time assessment of the histopathology of colorectal polyps (type 1, hyperplastic or inflammatory polyps; type 2, adenomatous polyps, intramucosal cancer, or superficial submucosal invasive cancer; type 3, deep submucosal invasive cancer; and type 4, normal mucosa). We also collected 116 consecutive polyp videos to validate the accuracy of the CAD-N. Results A total of 10,573 images (7,032 images from 650 polyps and 3,541 normal mucous membrane images) from 478 patients were finally chosen for analysis. The sensitivity, specificity, PPV, NPV, and accuracy for each type of the CAD-N in the test set were 89.86%, 97.88%, 93.13%, 96.79%, and 95.93% for type 1; 93.91%, 95.49%, 91.80%, 96.69%, and 94.94% for type 2; 90.21%, 99.29%, 90.21%, 99.29%, and 98.68% for type 3; and 94.86%, 97.28%, 94.73%, 97.35%, and 96.45% for type 4, respectively. The overall accuracy was 93%. We also built models for polyps ≤5 mm, and the sensitivity, specificity, PPV, NPV, and accuracy for them were 96.81%, 94.08%, 95%, 95.97%, and 95.59%, respectively. Video validation results showed that the sensitivity, specificity, and accuracy of the CAD-N were 84.62%, 86.27%, and 85.34%, respectively. Conclusions We have developed real-time AI-based histologic classifications of colorectal polyps using NBI images with good accuracy, which may help in clinical management and documentation of optical histology results.

Abstract
BACKGROUND Conventional treatment for Crohn disease (CD) in pregnancy includes mesalamine, thiopurine, and anti-tumor necrosis factor (TNF)-α agents. However, women may abstain because of complications, nonresponse, or potential adverse outcomes. Peptide-based formula therapy, through oral or nasogastric feeding without other food intake, is an effective and safe therapy for active CD. Herein, We confirmed the effectiveness and safety of peptide-based formula therapy for active CD in pregnant women or those preparing for pregnancy. METHOD Outcomes of peptide-based formula therapy to induce CD remission during pregnancy preparation and the conception period were evaluated retrospectively among 14 women. Efficacy was evaluated as the change in serum indices and inflammatory markers after 12-week treatment. Pregnancy outcomes were compared between 14 women treated with nutrition therapy and eight women using conventional CD drugs. RESULTS After 12 weeks, 85.7% (12 of 14) of patients treated with peptide-based formula achieved remission with a significant decrease in the CD activity index (P < .001) and high-sensitivity C-reactive protein level (P = .004). There were no effects of peptide-based formula therapy on pregnancy outcomes compared with conventional CD treatment (P > .05). Among the 12 patients who achieved CD remission with exclusive peptide-based formula therapy, 10 selected to continue total or partial peptide-based formula treatment to maintain CD remission throughout pregnancy. CONCLUSION Peptide-based formula therapy, without other food intake, may provide a safe and effective alternative to conventional CD drugs to induce disease remission among women during conception and pregnancy.

Abstract
Background and Aim The identification of ulcerative colitis (UC) and Crohn's disease (CD) is a key element interfering with therapeutic response, but it is often difficult for less experienced endoscopists to identify UC and CD. Therefore, we aimed to develop and validate a deep learning diagnostic system trained on a large number of colonoscopy images to distinguish UC and CD. Methods This multicenter, diagnostic study was performed in 5 hospitals in China. Normal individuals and active patients with inflammatory bowel disease (IBD) were enrolled. A dataset of 1,772 participants with 49,154 colonoscopy images was obtained between January 2018 and November 2020. We developed a deep learning model based on a deep convolutional neural network (CNN) in the examination. To generalize the applicability of the deep learning model in clinical practice, we compared the deep model with 10 endoscopists and applied it in 3 hospitals across China. Results The identification accuracy obtained by the deep model was superior to that of experienced endoscopists per patient (deep model vs. trainee endoscopist, 99.1% vs. 78.0%; deep model vs. competent endoscopist, 99.1% vs. 92.2%, P < 0.001) and per lesion (deep model vs. trainee endoscopist, 90.4% vs. 59.7%; deep model vs. competent endoscopist 90.4% vs. 69.9%, P < 0.001). In addition, the mean reading time was reduced by the deep model (deep model vs. endoscopists, 6.20 s vs. 2,425.00 s, P < 0.001). Conclusion We developed a deep model to assist with the clinical diagnosis of IBD. This provides a diagnostic device for medical education and clinicians to improve the efficiency of diagnosis and treatment.

Abstract
BACKGROUND Mesenteric adipose tissue (mAT) hyperplasia, known as creeping fat is a pathologic characteristic of Crohn's disease (CD). The reserve of creeping fat in surgery is associated with poor prognosis of CD patients, but the mechanism remains unknown. METHODS Mesenteric microbiome, metabolome, and host transcriptome were characterized using a cohort of 48 patients with CD and 16 non-CD controls. Multidimensional data including 16S ribosomal RNA gene sequencing (16S rRNA), host RNA sequencing, and metabolome were integrated to reveal network interaction. Mesenteric resident bacteria were isolated from mAT and functionally investigated both in the dextran sulfate sodium (DSS) model and in the Il10 gene-deficient (Il10-/-) mouse colitis model to validate their pro-inflammatory roles. RESULTS Mesenteric microbiota contributed to aberrant metabolites production and transcripts in mATs from patients with CD. The presence of mAT resident microbiota was associated with the development of CD. Achromobacter pulmonis (A. pulmonis) isolated from CD mAT could translocate to mAT and exacerbate both DSS-induced and Il10 gene-deficient (Il10-/-) spontaneous colitis in mice. The levels of A. pulmonis in both mAT and mucous layer from CD patients were higher compared to those from the non-CD group. CONCLUSIONS This study suggests that the mesenteric microbiota from patients with CD sculpt a detrimental microenvironment and promote intestinal inflammation. Video abstract.

Abstract
BACKGROUND Ustekinumab (UST), a newly-used biologic targeting p40 subunit of IL12 and IL23 in China, exerts a confirmed therapeutic effect on the induction and maintenance therapies for refractory Crohn's disease (CD). Therapeutic drug monitoring based on trough and antibody concentration is of core importance when treating patients who lose response to UST. We aimed to analyze the UST exposure-response relationship in CD treatment in the real-world setting. METHODS We retrospectively enrolled patients with CD who received UST between March 1, 2020 and May 31, 2021, at the inflammatory bowel disease (IBD) center of the Sun Yat-Sun Affiliated Sixth Hospital. Baseline characteristic information, biomarker examination, clinical outcomes determined by the Crohn's disease activity index (CDAI), and endoscopic outcomes evaluated using a simple endoscopic score for Crohn's disease (SES-CD) at week 16/20 were collected. The optimal UST cut-off trough concentration was identified using receiver operating characteristic curve (ROC) analysis. RESULTS Nineteen eligible patients were included in the study, the mean age was 29.1 ± 9.1 years and the mean disease duration was 5.5 ± 4.7 years. At the initiation of the study, 89.5% of the patients had been exposed to prior biologics, 42.1% had previous CD-related surgeries, and 52.6% had perianal diseases. At week 16/20 after the UST initiation, clinical response, clinical remission, endoscopic response, and endoscopic remission were 89.5%, 84.2%, 42.2%, and 73.7%, respectively. The cut-off optimal trough concentration for UST was 1.12 μg/mL, as determined by the ROC with an area under the curve (AUC) of 0.78, sensitivity of 87.5%, and specificity of 72.7%. Patients with a UST trough concentration > 1.12 μg/mL had a significantly higher rate of endoscopic remission than those without (70.0% vs. 11.1%, P = 0.02).

Abstract
Background Sometimes in clinical practice, it is a great challenge to distinguish Crohn's disease (CD) and intestinal tuberculosis (ITB), we conducted this study to identify simple and useful algorithm for distinguishing them. Methods We retrospectively reviewed the medical history of the patients who were diagnosed as ITB or CD. We firstly identified ITB patients, and then the patients diagnosed with CD were matched by age, sex, and admission time in a 1:1 ratio. Patients who admitted between May 1, 2013 and April 30, 2019 were regarded as training cohort, and patients admitted between May 1, 2019 and May 1, 2020 were regarded as validation cohort. We used multivariate analysis to identify the potential variables, and then we used R package rpart to build the classification and regression tree (CART), and validated the newly developed model. Results In total, the training cohort included 84 ITB and 84 CD patients, the validation cohort included 22 ITB and 22 CD patients. Multivariate analysis showed that, positive interferon-gamma release assays (IGRAs), ≥ 4 segments involved, longitudinal ulcer, circular ulcer, and aphthous ulcer were confirmed as independent discriminating factors. Using these parameters to build the CART model made an overall accuracy rate was 88.64%, with sensitivity, specificity, NPV, and PPV being 90.91%, 86.36%, 90.48% and 86.96%, respectively. Conclusion We developed a simple and novel algorithm model covering laboratory, imaging, and endoscopy parameters with CART to differentiate ITB and CD with good accuracy. Positive IGRAs and circular ulcer were suggestive of ITB, while ≥ 4 segments involved, longitudinal ulcer, and aphthous ulcer were suggestive of CD.

Abstract
BACKGROUND Predicting aggressive Crohn's disease is crucial for determining therapeutic strategies. OBJECTIVE We aimed to develop a prognostic model to predict complications leading to surgery within 1 year after diagnosis of Crohn's disease and to create a nomogram to facilitate clinical decision making. DESIGN This is a retrospective study. SETTING This study was conducted from January 2012 to December 2016 in a single tertiary IBD center. PATIENTS Patients diagnosed with Crohn's disease showing B1 behavior according to the Montreal classification were included. MAIN OUTCOME MEASURES We measured the occurrence of complications that would ultimately lead to surgery, including severe GI bleeding (Glasgow-Blatchford score ≥6), stenosis, and perforations, confirmed by endoscopy, CT scan, and/or interventional radiology. RESULTS The mean follow-up period was 54 months (SD 13 months). Of the 614 eligible patients, 13.5% developed complications leading to surgery. Multivariable logistic regression revealed the independent predictors of early-onset complications to be age (adjusted odds ratio per 10-year increase in age = 0.4; 95% CI, 0.2-0.8; p = 0.004), disease duration (adjusted odds ratio = 2.7, 95% CI, 1.9-3.8; p < 0.001), perianal disease (adjusted odds ratio = 16.0; 95% CI, 4.3-59.9; p < 0.001), previous surgery (adjusted odds ratio = 3.7; 95% CI, 1.6-8.6; p = 0.003), and extraintestinal manifestations (adjusted odds ratio = 7.6; 95% CI, 2.3-24.9; p = 0.001). The specificity and sensitivity of the prognostic model were 88.3% (95% CI, 84.8%-91.2%) and 96.6% (95% CI, 88.1%-99.6%), and the area under the curve was 0.97 (95% CI, 0.95-0.98). This model was validated with good discrimination and excellent calibration using the Hosmer-Lemeshow goodness-of-fit test. A nomogram was created to facilitate clinical bedside practice. LIMITATIONS This was a retrospective design and included a small sample size from 1 center. CONCLUSIONS Our validated prognostic model effectively predicted early-onset complications leading to surgery and screened aggressive Crohn's disease, which will enable physicians to customize therapeutic strategies and monitor disease.

UN MODELO DE PRONSTICO VALIDADO Y UN NOMOGRAMA PARA PREDECIR COMPLICACIONES PRECOCES QUE REQUIRAN CIRUGA EN PACIENTES CON ENFERMEDAD DE CROHN ANTECEDENTES:Predecir una enfermedad de Crohn muy agresiva es fundamental para determinar la estrategia terapéutica.OBJETIVO:Desarrollar un modelo de pronóstico para predecir las complicaciones que requieran cirugía dentro el primer año al diagnóstico de enfermedad de Crohn y crear un nomograma para facilitar la toma de decisiones clínicas.DISEÑO:El presente etudio es retrospectivo.AJUSTE:Estudio realizado entre Enero 2012 y Diciembre 2016, en un único centro terciario de tratamiento de enfermedad inflamatoria intestinal.PACIENTES:Se incluyeron todos aquellos pacientes diagnosticados de enfermedad de Crohn que mostraban manifestaciones tipo B1 según la clasificación de Montreal.PRINCIPALES MEDIDAS DE RESULTADO:Medimos la aparición de complicaciones que finalmente conducirían a una cirugía, incluida la hemorragia digestiva grave (puntuación de Glasgow-Blatchford ≥ 6), estenosis y perforaciones, confirmadas por endoscopía, tomografía computarizada y / o radiología intervencionista.RESULTADOS:El período medio de seguimiento fue de 54 meses (desviación estándar 13 meses). De los 614 pacientes elegibles, el 13,5% desarrolló complicaciones que llevaron a cirugía. La regresión logística multivariable reveló que los predictores independientes de complicaciones de inicio temprano eran la edad (razón de probabilidades ajustada [ORa] por aumento de 10 años en la edad = 0,4; intervalos de confianza del 95% [IC del 95%]: 0,2-0,8, p = 0,004), duración de la enfermedad (ORa = 2,7, IC del 95%: 1,9-3,8, p <0,001), enfermedad perianal (ORa = 16,0, IC del 95%: 4,3-59,9, p <0,001), cirugía previa (ORa = 3,7, 95% IC: 1,6-8,6, p = 0,003) y manifestaciones extraintestinales (ORa = 7,6, IC del 95%: 2,3-24,9, p = 0,001). La especificidad y sensibilidad del modelo pronóstico fueron 88,3% (IC 95%: 84,8% -91,2%) y 96,6% (IC 95%: 88,1% -99,6%), respectivamente, y el área bajo la curva fue 0,97 (95% % CI: 0,95-0,98). Este modelo fue validado con buena discriminación y excelente calibración utilizando la prueba de bondad de ajuste de Hosmer-Lemeshow. Se creó un nomograma para facilitar la práctica clínica al pié de la cama.LIMITACIONES:Diseño retrospectivo que incluyó un tamaño de muestra pequeña en un solo centro.CONCLUSIONES:Nuestro modelo de pronóstico validado predijo eficazmente las complicaciones precoces que conllevaron a cirugía y la detección de enfermedad de Crohn agresiva, lo que permitió a los médicos personalizar las estrategias terapéuticas y controlar la enfermedad.

Abstract
Background: Some studies showed that small bowel involved Crohn’s Disease (CD) was more serious, which required early identification and aggressive treatment. However, studies investigating small bowel involved CD, especially isolated small bowel CD with large sample size, are limited.
Methods: From November 2013 to August 2018, consecutive patients who were confirmed to have small bowel involved CD by double-balloon enteroscopy (DBE) were retrospectively reviewed. They were divided into two groups based on whether colon involved: isolated small bowel involved (case group) and small bowel + colon involved (control group).
Results: 204 patients (154 males and 50 females) with small bowel involved CD (98 in case group and 106 in control group) were chosen. Compared with the control group, the case group had a higher proportion of bowel resection history and stricturing behaviour, while had a lower proportion of elevated platelet and erythrocyte sedimentation rate level. The two groups had no difference in bowel resection risk since the DBE procedure (P=0.277), but the case group had a higher probability since the onset of the symptoms (P=0.003). Diagnosis at > 40-year-old, thickest bowel wall>7mm, and stricture found in DBE were risk factors for bowel resection, while patients with irregular ulcer, received infliximab, corticosteroids, or enteral nutrition after DBE may have a lower risk.
Conclusion: The isolated small-bowel CD was concealed and would be easily overlooked, though they may be more serious. The prognosis might not be as bad as it used to be considered if the disease could be diagnosed, evaluated comprehensively, and treated appropriately early.

Abstract
The skewed T helper (Th) 2 response plays a critical role in the pathogenesis of allergic asthma. Regulatory T (Treg) cells and the regulatory cytokines are required in maintaining the homeostasis in the body. This study aims to determine the effects of a poly(lactic-co-glycolic) acid (PLGA)-ovalbumin (OVA)+A20 (a ubiquitin E3 ligase) nanovaccine on inhibiting allergic asthma in a murine model. In this study, A20 and OVA (a model antigen) were encapsulated into PLGA to be a nanovaccine (PLGA-OVA+A20). An allergic asthma murine model was developed with OVA as the specific antigen to test the role of PLGA-OVA+A20 nanovaccine in maintaining the immune homeostasis in the airway tissues. The results showed that PLGA-OVA+A20 nanovaccine inhibited the asthma responses in mice by suppressing Th2 inflammatory responses, promoting the generation of Treg cells in the airway tissues. We conclude that the PLGA-OVA+A20 nanovaccine has a marked inhibitory effect on the airway allergic response in sensitized mice by significantly promoting the generation of Treg cell and IL-10. The data suggest that PLGA-OVA+A20 has translational potential in the treatment of allergic asthma.

Abstract
BACKGROUND The aim of this study was to evaluate the experience of surgery in IBD patients during the COVID pandemic. METHODS A survey was distributed among patients undergoing IBD-related surgeries from January 2020 to March 2020 via an online platform. The response was submitted anonymously. RESULTS A total of 78 patients responded to the survey. COVID-19 testing was conducted in 60 (76.9%) patients, and they were all tested negative. Emergent surgery was performed in 12 (15.4%) patients and postponed surgery in 18 (23.1%) patients. The surgical indications were mainly bowel obstruction (N = 21, 26.9%) and perianal abscess (N = 18, 23.1%). Postoperative complications were noted in 5.1% of cases, but no re-operation was required. Due to the ongoing COVID pandemic, 58 (74.4%) patients reported various levels of concern and anxiety for surgery. CONCLUSIONS Common surgical indications were for bowel obstruction and perianal abscess. Surgery can be postponed, but disease progression should be monitored closely and surgically intervened as needed. Most patients expressed anxiety resulting from the pandemic. The overall experience was satisfactory.

Abstract
BACKGROUND AND AIMS Sustained activation of CD4+ T cells plays important roles in the pathogenesis of Crohn's disease [CD]. Under physiologic conditions, activated T cells can be timely eliminated by a process termed activation-induced cell death [AICD], restraining T cell over-activation and preventing immunological destruction. We inquired whether defective AICD might explain CD4+ T cell over-activation in CD and investigated the underlying mechanisms. METHODS CD14+ macrophages [Mφ] and CD4+ T cells were isolated from intestinal tissues or peripheral blood of controls and CD patients. An ex vivo evaluation system was employed to simulate AICD and cell apoptosis was measured by flow cytometry. RESULTS CD4+ T cells from CD patients fail to undergo AICD in the ex vivo system. Specifically, proinflammatory type 1 helper T [Th1] and type 17 helper T [Th17] cells, rather than immunosuppressive regulatory T [Treg] cells evade AICD in CD. CD14+ Mφ in the intestinal inflammatory microenvironment of CD promote AICD resistance in CD4+ T cells via a cell-to-cell contact-independent manner. Mechanistically, CD14+ Mφ released exosomes express membrane tumour necrosis factor [TNF] which engages TNFR2 on CD4+ T cells and triggers NF-κB signalling, thereby causing AICD resistance. Importantly, clinically applicable anti-TNF antibodies effectively blocked exosomal membrane TNF-induced CD4+ T cell AICD resistance. CONCLUSIONS CD14+ Mφ participate in CD pathogenesis by inducing AICD resistance through release of exosomal membrane TNF to activate the TNFR2/NF-κB pathway in CD4+ T cells. These results present new insights into CD pathogenesis and extend mechanistic understanding of anti-TNF agents. PROPOSED MODEL CD14+ Mφ in the intestinal microenvironment of CD patients maintain the sustained activation of CD4+ T cells through exosomal membrane TNF to induce apoptosis resistance via TNFR2/NF-κB signalling, which could be effectively blocked by clinically applicable anti-TNF agents.

Abstract
We report on the first injection-seeded nanosecond Ti:Sapphire laser that demonstrates a stable single-longitudinal-mode operation with no feedback loop for active cavity stabilization. The short cavity generates 6-mJ transform-limited pulses at a wavelength of 807 nm and with a slope efficiency of 43%. An intracavity dispersive prism makes a novel cavity design for injection-seeded lasers and provides pre-selection of the emission wavelength. In support of these experiments, we perform numerical simulations that include extra cavity losses. The simulation results are in good agreement with the outcome of the experiment and reveal the formation scenario of the laser mode.

Abstract
In December 2017, an influenza A(H9N2) virus (B51) was isolated from migratory waterfowl in Hubei Province, China. Phylogenetic analysis demonstrated that B51 is a novel reassortant influenza virus containing segments from human H7N4 virus and North American wild bird influenza viruses. This suggest that B51 has undergone multiple reassortment events.

Abstract
BACKGROUND Accelerated therapeutic treatment should be considered in patients with progressive Crohn’s disease (CD) to prevent complications as well as surgery. Therefore, screening for risk factors and predicting the need for early surgery are of great importance in clinical practice.
AIM To establish a model to predict CD-related early surgery.
METHODS This was a retrospective study collecting data from CD patients diagnosed at our inflammatory bowel disease center from January 1, 2012 to December 31, 2016. All data were randomly stratified into a training set and a testing set at a ratio of 8:2. Multivariable logistic regression analysis was conducted with receiver operating characteristic curves constructed and areas under the curve calculated. This model was further validated with calibration and discrimination estimated. A nomogram was finally developed.
RESULTS A total of 1002 eligible patients were enrolled with a mean follow-up period of 53.54 ± 13.10 mo. In total, 24.25% of patients received intestinal surgery within 1 year after diagnosis due to complications or disease relapse. Disease behavior (B2: OR [odds ratio] = 6.693, P < 0.001; B3: OR = 14.405, P < 0.001), smoking (OR = 4.135, P < 0.001), body mass index (OR = 0.873, P < 0.001) and C-reactive protein (OR = 1.022, P = 0.001) at diagnosis, previous perianal (OR = 9.483, P < 0.001) or intestinal surgery (OR = 8.887, P < 0.001), maximum bowel wall thickness (OR = 1.965, P < 0.001), use of biologics (OR = 0.264, P < 0.001), and exclusive enteral nutrition (OR = 0.089, P < 0.001) were identified as independent significant factors associated with early intestinal surgery. A prognostic model was established and further validated. The receiver operating characteristic curves and calculated areas under the curves (94.7%) confirmed an ideal predictive ability of this model with a sensitivity of 75.92% and specificity of 95.81%. A nomogram was developed to simplify the use of the predictive model in clinical practice.
CONCLUSION This prognostic model can effectively predict 1-year risk of CD-related intestinal surgery, which will assist in screening progressive CD patients and tailoring therapeutic management.

Abstract
OBJECTIVE The prevalence of inflammatory bowel disease (IBD) has been increasing worldwide, and the risk of infection has increased due to the use of immunosuppressive and biologic medications. Some of these infections can be prevented with vaccinations. The aim of this study was to evaluate the vaccination practices of Chinese gastroenterologists for patients with IBD. METHODS Questionnaires based on quick response codes were sent using email and the WeChat platform to gastroenterologists at 20 hospitals in China. The vaccination practices of the gastroenterologists, including vaccinating for hepatitis B, hepatitis A, and varicella, were assessed. RESULTS Of the 468 gastroenterologists who received the questionnaire, 307 (65.6%) completed it. Of the gastroenterologists who were most concerned about hepatitis B; 83.4% always or frequently asked about an infection history, 53.7% took an immunization history, and 73.6% tested patients for hepatitis B infection. However, few gastroenterologists did so for hepatitis A or varicella. The proportion of patients who were asked about an infection and immunization history and tested for varicella infection was 16.0%, 15.0%, and 9.4%, respectively. Only a few gastroenterologists recommended vaccination for patients without an infection before IBD medical treatment (26.7% for hepatitis A, 45.6% for hepatitis B, and 28% for varicella vaccination). CONCLUSION Vaccination practices for patients with IBD used by Chinese gastroenterologists vary greatly, suggesting that education about immunization is needed.

Abstract
Background Although 90 susceptibility loci of Crohn’s disease (CD) have been confirmed in the Asian population, susceptibility genes for perianal fistula of CD (pCD) in this population remain unknown. This study explored susceptibility genes for CD and pCD in the Han population from South China. Material/Methods In total, 490 patients diagnosed with CD between July 2012 and June 2016 at the Sixth Affiliated Hospital of Sun Yat-sen University were included and divided into the CD group (n=240) and the pCD group (n=250). The healthy control group was composed of 260 volunteers. Peripheral blood samples were taken, and single nucleotide polymorphism (SNP) locus sequencing was used to screen for susceptibility loci. SNPs were sequenced using matrix-assisted laser desorption ionization time-of-flight mass spectrometry. Results Nine SNPs in TNFSF1 on chromosome 9 were associated with CD. Among them, the rs6478106 locus is a risk locus for CD. The distribution frequency of the T allele of the rs6478106 SNP was significantly different between cases and controls (32.49% versus 18.27%, P<0.001). Rs72553867, located in the IRGM gene on chromosome 5, rs4409764, located in the NKX2–3 gene on chromosome 10, and rs3731772, located in the AOX1 gene on chromosome 2, were susceptibility factors for pCD. Nine SNPs located in TNFSF15 on chromosome 9 were related to CD in Han individuals from Southern China. Conclusions The rs6478106 T allele is associated with the risk of CD in the investigated population. SNPs rs72553867 (IRGM gene), rs4409764 (NKX2–3 gene), and rs3731772 (AOX1 gene) increase the risk of pCD.

Abstract
Five novel H5N6 influenza viruses, including four highly pathogenic avian influenza viruses and one low pathogenic avian influenza virus, were isolated from migratory birds in Ningxia, China, in November 2017. To understand the genetic origination of the novel H5N6 virus, and the infectivity and pathogenicity of the four highly pathogenic avian influenza viruses in mammals, phylogeographic analyses and infection studies in mice were performed. The phylogenetic and phylogeographic analyses showed that the H5N6 isolates, which are closely related to the viruses from Korea, Japan and the Netherlands, originated from reassortant virus between H5N8 and HxN6 viruses from western Russia. The animal study revealed that the SBD-87 isolate presented moderate virulence in mice, suggesting a potential public risk to humans and a potential threat to public health.

Abstract
Background Currently, WeChat is widely used in disease education for patients with Crohn’s disease (CD) in China. It is beneficial for the patients to actively engage in their disease management. Methods In this study, we examined the source and expectations of disease information for Chinese CD patients, analysing the content of popular WeChat public accounts and their potential association with medication adherence. Results Between November 24th, 2017 and April 10th, 2018, online questionnaires were sent to CD patients from eight different large urban hospitals in China. In all, 436 patients with CD were surveyed, and 342 patients responded. Patients most frequently visited Baidu (65%), WeChat (61%) and medical websites such as Haodaifu (35%) when searching for IBD-related information. Among ten WeChat IBD public accounts, the China Crohn’s and Colitis Foundation (CCCF) (73%), “IBD Academic Officer” (21%) and “IBD in love” (21%) were the most popular. CD patients were most interested in information from the internet about diet and day-to-day health-related living with IBD (83%), an introduction to the disease (80%), and medication advances and side effects (80%). The correlation between the information provided by the top five WeChat public accounts and patients’ expectations was low. Additionally, most patients (64%) had greater confidence in overcoming the disease after learning about CD through their internet searches. Medical adherence was also related to internet access and income (p < 0.05). Conclusions WeChat has become a major source of information for IBD education in China, but the content of WeChat didn’t fully meet patients’ expectations. Therefore, future initiatives should aim to provide high-quality information that based on patients’ demands.

Abstract
Objective The aims of this study were to 1) encapsulate ibuprofen (IBU) and basic fibroblast growth factor (bFGF) in a thermosensitive micellar hydrogel, 2) test the biological properties of this in situ drug delivery system, and 3) study the effect of hydrogel in promoting soft tissue healing after implant surgery and its anti-inflammatory function as an early local treatment of peri-implantitis. Materials and methods A thermosensitive micellar hydrogel was prepared from amphiphilic copolymer poly(ε-caprolactone-co-1,4,8-trioxa [4.6]spiro-9-undecanone)-poly(ethylene glycol)-poly(ε-caprolactone-co-1,4,8-trioxa [4.6]spiro-9-undecanone) (PECT) nanoparticles and tested in vitro using a scanning electron microscope, rheometer, UV spectrophotometer, HPLC, and transmission electron microscope. Results The bFGF + IBU/PECT hydrogel formed a stable, water-dispersible nanoparticle core shell that was injectable at room temperature, hydrogel in situ at body temperature, and provided sustained release of both hydrophilic and hydrophobic drugs. The hydrogel promoted the proliferation and adhesion of human gingival fibroblasts, upregulated the expression of adhesion factors such as vinculin proteins, and showed anti-inflammatory properties. Conclusion In situ preparation of IBU-and bFGF-loaded PECT hydrogel represents a promising drug delivery system with the potential to provide early local treatment for peri-implantitis.
