Zhang X, Zhou L and Qian X
Ankylosing spondylitis (AS) and inflammatory bowel disease (IBD) are prevalent autoimmune disorders that often co-occur, posing significant treatment challenges. This investigation adopts a multidisciplinary strategy, integrating bioinformatics, network pharmacology, molecular docking, and Mendelian randomization, to elucidate the relationship between AS and IBD and to investigate the potential mechanisms of traditional Chinese medicine formulations, represented by Qiangji Jianpi (QJJP) decoction, in treating these comorbid conditions.
Yinchenhao Decoction Protects Against Acute Liver Injury in Mice With Biliary Acute Pancreatitis by Regulating the Gut Microflora-Bile Acids-Liver Axis
Zhao X, Wu X, Hu Q, Yao J, Yang Y, Wan M and Tang W
Acute liver injury (ALI) often follows biliary acute pancreatitis (BAP), but the exact cause and effective treatment are unknown. The aim of this study was to investigate the role of the gut microflora-bile acids-liver axis in BAP-ALI in mice and to assess the potential therapeutic effects of Yinchenhao decoction (YCHD), a traditional Chinese herbal medicine formula, on BAP-ALI. Male C57BL/6 mice were allocated into three groups: negative control (NC), BAP model, and YCHD treatment groups. The severity of BAP-ALI, intrahepatic bile acid levels, and the gut microbiota were assessed 24 h after BAP-ALI induction in mice. Our findings demonstrated that treatment with YCHD significantly ameliorated the severity of BAP-ALI, as evidenced by the mitigation of hepatic histopathological changes and a reduction in liver serum enzyme levels. Moreover, YCHD alleviated intrahepatic cholestasis and modified the composition of bile acids, as indicated by a notable increase in conjugated bile acids. Additionally, 16S rDNA sequencing analysis of the gut microbiome revealed distinct alterations in the richness and composition of the microbiome in BAP-ALI mice compared to those in control mice. YCHD treatment effectively improved the intestinal flora disorders induced by BAP-ALI. Spearman's correlation analysis revealed a significant association between the distinct compositional characteristics of the intestinal microbiota and the intrahepatic bile acid concentration. These findings imply a potential link between gut microbiota dysbiosis and intrahepatic cholestasis in BAP-ALI mice and suggest that YCHD treatment may confer protection against BAP-ALI via the gut microflora-bile acids-liver axis.

Although endoscopic balloon dilation (EBD) is a common therapeutic approach for managing strictures associated with Crohn's disease (CD), the clinical application and complication rates of EBD remain unclear. We collected admission data for patients who underwent EBD using a nationwide database. We compared EBD outcomes between ileal and colonic strictures, CD and ulcerative colitis, and CD and anastomotic strictures arising from cancer-related surgery. Subsequently, propensity score matching was employed to facilitate comparisons between each group. The median duration of hospital stay was 4 days. Endoscopic hemostasis and urgent surgery rates after EBD for CD-related strictures were considerably low (0.035% and 0.11%, respectively). Most patients with CD underwent only one EBD procedure during a single admission. Although no significant differences in patient backgrounds and severe complications were observed between ileal and colonic stricture in CD, multiple EBD procedures were more commonly performed for ileal strictures than for colonic stricture. Moreover, EBD for ileal stricture was more frequently conducted in high-volume centers than in low-volume centers. Regarding severe complications after EBD, no significant differences were observed between CD-related strictures and ulcerative colitis or anastomotic strictures related to cancer surgery. Our findings support the safe and effective use of EBD for both ileal and colonic strictures associated with CD. The clinical practice and safety outcomes of EBD for CD-related strictures were comparable to those for strictures stemming from other etiologies.

C-Reactive Protein Is Not the Driver Factor in Ulcerative Colitis
Ge ZB, Zhang XY, Zhang CM, Xu TT, Li SY, Wei MX, Ding XY, Bai CJ, Wang H, Zhou HH and Wang MY
: C-reactive protein (CRP) functions as a nonspecific marker in various inflammatory disorders, particularly in evaluating the efficacy of pharmacological treatments in patients with ulcerative colitis. The existing body of evidence does not offer adequate support for the direct implication of CRP in modulating the advancement of ulcerative colitis. : Our study employed a rigorous mouse model. An ulcerative colitis mouse model was established by subjecting CRP-deficient mice to dextran sulfate sodium (DSS) treatment. The phenotype of the mice, which encompassed parameters such as body weight, colon length, and spleen weight, was meticulously evaluated. Additionally, various physiological and biochemical indicators were assessed, including colon histopathology, expression levels of inflammatory factors, and staining of the intestinal mucus layer. The absence of CRP did not significantly affect the phenotype, physiological characteristics, and biochemical indices in a mouse model of ulcerative colitis compared to mice with wild-type CRP. Additionally, eliminating intestinal bacteria flora interference through antibiotic treatment revealed that mice lacking CRP did not demonstrate any notable variations in the ulcerative colitis model. Meanwhile, the survival rate of mice lacking CRP did not exhibit a statistically significant difference compared to wild-type mice. The results of our study suggest that CRP may not directly mediate ulcerative colitis. Instead, it is more likely to be a bystander that is present alongside with elevated inflammatory factors. Further investigation is warranted to determine the precise role of CRP in humans, given the significant limitations associated with the use of mouse models.

Modified Endoscopic Submucosal Dissection-An Alternative Modality for the Treatment of Sporadic Duodenal Papillary Adenomas
Han Z, Li Q, Chua CY, Wang Z, Zhong J, Huang Y, Huang S, Li A, Liu S and Luo X
Endoscopic submucosal dissection (ESD) is commonly employed in the treatment of epithelial gastrointestinal tumors, but few studies have explored ESD for treatment of duodenal papillary adenomas (PAs). In this study, we aim to evaluate the feasibility of a modified ESD method as an alternative modality in the resection of PAs. We evaluated potential advantages of modified ESD for resection of sporadic duodenal PAs through retrospective analysis of 10 PAs resected via ESD compared to paired lesions undergoing endoscopic papillectomy (EP). All lesions undergoing ESD were resected en bloc with negative margins, compared to 60% of lesions undergoing EP. Within the experimental group, there was one case each of melena and pancreatitis compared to four bleeds and one case of pancreatitis in the control group. No recurrence was detected within the ESD group after a mean follow-up time of 11.2 months compared to three recurrences within a mean follow-up time of 27.7 months. From our preliminary experience, ESD is a promising alternative in the treatment of superficial duodenal PAs; however, further investigation is needed.
Monocyte CD36 Expression Predicts Disease Activity in Patients With Crohn's Disease
Zhu J, Zhu N, Wang J, Liu Q and Mei Q
Crohn's disease (CD) is a chronic intestinal inflammatory disease associated with genetic, environmental, and other unknown factors. Cluster of differentiation 36 (CD36) plays an important role in cancer, inflammation, and metabolic diseases. Although CD36 has recently been implicated in various diseases, its role in CD is still unclear. Blood samples were collected from patients with CD and healthy volunteers. Peripheral blood mononuclear cells (PBMCs) were isolated by density gradient centrifugation over Ficoll-Paque and labeled with monoclonal antibodies (CD14-APC and CD36-PE). Flow cytometer CytoFlex is used for analysis. Twenty-nine patients with CD in remission, 42 patients with active CD, and 23 healthy volunteers were included in the study. Our results showed that the frequency of the CD14+CD36+ monocyte subset was increased in PBMCs from patients with active CD compared with patients in remission and healthy controls. However, CD36 on monocytes was lower in CD compared with the healthy controls. CD36 expression was decreased in patients with active CD compared with that of patients with CD in remission and healthy control subjects, but no difference was found between patients with CD in remission and healthy controls. Interestingly, we found negative correlations of CD36 with HBI, SES-CD, C-reactive protein, and neutrophil-to-lymphocyte ratio. These data indicate that monocyte CD36 associates with disease activity in CD and might be a potential biomarker for assessing the activity of CD.
Beneficial Alterations of Intestinal Microbiota in Chronic Cholecystitis Patients Treated With NOTES Gallbladder-Preserving Surgery
Deng L, Lv X, Wang T, Huang X, Huang Q, Li X, Wen C, Chen L, Chen H and Zhang M
NOTES gallbladder-preserving surgery (N-GPS) has been heralded as a new paradigm shift in minimally invasive surgery for chronic cholecystitis patients. The objective of this research was to evaluate the impact of N-GPS on the intestinal microbiota of patients. The study selected patients with benign gallbladder disease (BG group) within 1 week preoperative (BG_DPR stage) and followed up over 1 year postoperative (BG_YPO stage) and selected healthy controls (HC group) whose sex, age, and BMI index matched with patients at BG_YPO stage, too. Accordingly, stool samples from healthy controls and two stages of patients with benign gallbladder disease were collected; among them, the selected samples were sent for 16S rDNA sequencing with Illumina MiSeq platform, and then, the combined samples were sent for short-chain fatty acid (SCFA) analysis with GC-MS platform. The result of alpha diversity of Shannon index showed that the difference among the two stages of BG group and HC group wasn't statistically significant, while the result of beta diversity based on the weighted UniFrac distance suggested that the structure of intestinal microbiota of BG group at YPO stage was closer to HC group. LEfSe analysis suggested that BG_YPO stage enriched genus, such as and , which improved bile acid metabolism. Compared with BG_DPR stage, BG_YPO stage and HC group enriched and , but depleted , while fecal SCFA concentrations increased. Patients with benign gallbladder disease and chronic cholecystitis after N-GPS treatment for over 1 year improved gut microbial community structure. With the improving bile acid metabolism, SCFA-producing bacteria increased and pathobionts decreased, which helped the intestinal microbiota structure of BG group at YPO stage restore and close to HC group.

Li S, Zhu P, Chen F, Yu W, Xie L, Xia J, Jiao P, Cui P, Zhang C, Bai Y, Jiang G, Li H, Lou Y, Li G, Shan X and Wang X
We aim to examine the association between liver function-related indicators and gallstone disease (GSD) risk. The subjects who participated in the China Multicenter Physical Examination Cohort (CMPEC) were enrolled. Relative odds ratios (ORs) with 95% CIs and standardized mean differences (SMDs) were applied to investigate the effect of liver function-related indicators and GSD risk. Moreover, a systematic review and meta-analysis were conducted until July 2021. Additionally, the results in the CMPEC and the systematic review and meta-analysis were combined by meta-analysis. Finally, the results were validated by a cohort study of the UK Biobank (UKB). Totally, 369,931 subjects in CMPEC were included in the study. A total of 28 publications were incorporated into the systematic review and meta-analysis. The pooled analysis suggested that aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total protein (TP), and low albumin (ALB) were positively associated with the risk of GSD. Meanwhile, GSD present to have higher AST, ALT, gamma-glutamyl transferase (GGT), total bilirubin (TBil), globulin (G), and ALP levels and relatively lower TP and ALB levels than the healthy participants. These results were consistent when stratified by the study design, geographic background, and study quality. Only the association between ALP and GSD risk was validated in the UKB cohort. This study suggests liver function indicators were associated with GSD risk. The results may provide the basis for exploring the etiology of GSD and may help clinicians identify high-risk subjects.

The Worries of Out-of-Home Activities in Patients With Inflammatory Bowel Disease: A Survey Study During the COVID-19 Pandemic
Fei YH, Zhang MH, Zhang MN, Shen Z and Wang HG
Patients with inflammatory bowel disease (IBD) often experience worries related to travel due to frequent bowel movements. However, there is currently limited research focusing on the travel worries of patients with IBD. The aim of this study was to assess the level of worry regarding out-of-home activities in patients with IBD and identify factors associated with worry. This study included patients with IBD who visited the outpatient clinics between September 2020 and March 2022, during the COVID-19 pandemic. Participants completed a self-designed questionnaire, providing general clinical data and indicating their level of worry for out-of-home activities. A total of 529 patients with IBD completed the questionnaire. Patients with Crohn's disease (CD) had a higher proportion of individuals under 40 years old and males compared to patients with ulcerative colitis (UC). Regarding out-of-home activities, patients with UC expressed greater worry about going out and taking buses than patients with CD. However, there were no significant differences observed between the two groups in terms of travel worries and worries about finding public washrooms. A significant majority (85.4%) of patients with clinically active IBD expressed worries about not finding public washrooms when going out, while 46.7% of patients in clinical remission had similar worries. Moreover, the worry about finding public washrooms was higher in patients with UC compared to those with CD, both during the clinical activity and remission. This survey conducted during the COVID-19 pandemic reported worries among patients with IBD about out-of-home activities. The patients with clinically active IBD, especially UC, expressed worries about not finding public washrooms when going out. We highlight the actual psychological and quality of life challenges faced by patients with IBD.

Efficacy of Step-Down Therapy Using Vonoprazan for Symptomatic Mild Reflux Esophagitis
Ochiai Y, Kikuchi D and Hoteya S
Patient-reported outcomes (PROs) are becoming pivotal in managing gastroesophageal reflux disease (GERD). Current Japanese guidelines for GERD recommend vonoprazan (VPZ) as a treatment option for mild reflux esophagitis (RE). However, it has been hypothesized that 4 weeks of VPZ 20 mg is not always necessary for mild RE if the treatment outcome is based on patient symptoms. This study is aimed at elucidating the efficacy of a new tapering therapeutic strategy (step-down therapy) using VPZ for symptomatic mild RE based on PRO. This multicenter retrospective study examined VPZ's efficacy for step-down therapy between October 2021 and November 2022. Included were 63 consecutive patients from the outpatient clinics of Toranomon Hospital and Toranomon Hospital Kajigaya with symptoms associated with RE (frequency scale for the symptoms of GERD (FSSG) scores ≥ 8 points) and mild RE classified as the Los Angeles Classification Grade A or B. Step-down therapy was defined as a treatment period of 28 days. VPZ 20 mg was administered as the initial treatment. Afterward, patients were allowed to step down to VPZ 10 mg if their symptoms improved, and VPZ could be discontinued if symptoms disappeared. If symptoms worsened, the dosage could be increased from 10 to 20 mg VPZ, or VPZ could be restarted at 20 mg after discontinuation. The proportion of patients whose FSSG scores decreased by ≥ 3 points with step-down therapy was 76.2% (48/63 patients). The median FSSG scores before and after step-down therapy were 13 (range, 8-35) and 7 (range, 0-29), respectively ( < 0.01). Overall, 71.4% (45/63) of the patients stepped down from 20 to 10 mg VPZ, and 46% (29/63) of the patients discontinued VPZ. Step-down therapy using VPZ may be a viable treatment option for symptomatic patients with mild RE.
