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
Radiation-induced intestinal injury (RIII) frequently occurs during radiotherapy; however, methods for treating RIII are limited. Ginsenoside Rk1 (RK1) is a substance that is derived from ginseng, and it has several biological activities, such as antiapoptotic, antioxidant and anticancer activities. The present study was designed to investigate the potential protective effect of Rk1 on RIII and the potential mechanisms. The results showed that RK1 treatment significantly improved the survival rate of the irradiated rats and markedly ameliorated the structural injury of the intestinal mucosa observed by histology. Treatment with RK1 significantly alleviated radiation-induced intestinal epithelial cell oxidative stress apoptosis. Moreover, RNA-Seq identified 388 differentially expressed genes (DEGs) and showed that the PI3K-AKT pathway might be a key signaling pathway by which RK1 exerts its therapeutic effects on RIII. The western blotting results showed that the p-PI3K, p-AKT and p-mTOR expression levels, which were increased by radiation, were markedly inhibited by Rk1, and these effects were reversed by IGF-1. The present study demonstrates that Rk1 can alleviate RIII and that the mechanism underlying the antiapoptotic effects of RK1 may involve the suppression of the PI3K/Akt/mTOR pathway. This study provides a promising therapeutic agent for RIII.

Abstract
BACKGROUND To explore whether simulation-based endovascular training with focus on radiation safety could improve correct behavior without jeopardizing the learning of procedural skills. METHODS Twenty-four residents without previous endovascular experience completed 10 clinical scenarios on a virtual-reality endovascular simulator with software for peripheral endovascular interventions. Participants were randomized to receive feedback (n = 12) or not (n = 12) on radiation protection (RP) performance after each case. Expert assessments were done at the first, second, fourth, seventh, and 10th case on RP and endovascular skills (ES). Automatic simulator metrics on procedure time, contrast dose, handling errors, and estimated radiation exposure to patient and operator were registered. Outcome metrics were analyzed by two-way mixed analysis of variance pairwise comparisons with independent t-tests. Correlations were explored using Pearson's r for internal consistency reliability. RESULTS The RP performance was similar in both groups at their first attempt (P = 0.61), but the feedback group significantly outperformed the control group over time (P < 0.001 for all comparisons). The feedback group was however slower to learn the ES at start (P = 0.047 at second performance), but after 7 attempts no difference was shown (P = 0.59). The feedback group used more time (19.5 vs. 15.3 min; P = 0.007) but less contrast (60 vs. 100 mL; P < 0.001). The number of errors was the same in both groups, but all metrics regarding radiation exposure favored the feedback group (P-values from 0.001 to 0.008). CONCLUSIONS Simulation-based training (SBT) is effective to acquire basic endovascular intervention skills and concurrently learn RP behavior when feedback on radiation culture is provided.

Abstract
Non-toxigenic Bacteroides fragilis is regarded as a potential candidate for probiotic owing to its various advantages. We previously isolated a new strain of B. fragilis (ZY-312) and verified its biosafety and capability of inhibiting the growth of pathogens in vivo. However, the colonization of ZY-312 in gastrointestinal (GI) tract remains to be determined. To track the colonization of ZY-312, mice were gavaged with ZY-312 labeled by means of metabolic oligosaccharide engineering and bioorthogonal click chemistry or given AF647-dibenzocyclooctyne (DIBO) directly. Then the fluorescence was detected in GI tract, spleen and kidneys. Results showed that ZY-312 could be labeled by metabolic oligosaccharide engineering, and the optimal incubation time with AF647-DIBO was 5 h in vitro. Following oral gavage with AF647-DIBO labeled ZY-312 or AF647-DIBO alone, mice were subjected to in vivo imaging and the fluorescence intensity was similar in both groups 3 h, 6 h, and 12 h post the gavage. The fluorescence of AF647-DIBO group disappeared 24 h post gavage which was probably due to the excretion via GI tract. While the fluorescence of AF647-DIBO labeled ZY-312 retained in the cecum for as long as 48 h. Immunofluorescence assay further confirmed that labeled ZY-312 transiently colonized not only in cecum but also in stomach, ileum and colon of mice 48 h post-gavage and that no massive accumulation of ZY-312 was detected in other organs such as kidneys and spleen. In conclusion, ZY-312 could transiently colonize in GI tract, mainly in cecum, for at least 48 h, and it hardly disseminate to other organs, which shed new light on the future development of B. fragilis as a probiotic product.

Abstract
BACKGROUND AND AIM Efficacy of rectal non-steroidal anti-inflammatory drugs (NSAIDs) for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) prophylaxis in unselected patients remained controversial. The aim of the present study was to evaluate the efficacy of rectal NSAIDs in the prevention of PEP in unselected patients. METHODS An electronic literature search in the Cochrane Library, Embase, and PubMed was carried out for randomized controlled trials comparing rectal indomethacin or diclofenac with placebo in the prevention of PEP in unselected patients. Cochrane risk of bias tool was used to evaluate methodological quality. The data were carried out in forest plots using fixed-effect methods, and random-effect methods were used when heterogeneity was significant. RESULTS A total of nine trials were included in our final analysis. Rectal NSAIDs were effective to reduce the incidence of PEP in unselected patients (RR, 0.61; 95% CI, 0.46-0.79), especially for moderate-to-severe PEP (RR, 0.37; 95% CI, 0.17-0.79). Both indomethacin (RR, 0.67; 95% CI, 0.50-0.88) and diclofenac (RR, 0.29; 95% CI, 0.12-0.69) were significantly efficacious. Rectal NSAIDs given pre-ERCP showed significant efficacy (RR, 0.53; 95% CI, 0.39-0.71), whether when given within 30 min pre-ERCP (RR, 0.62; 95% CI, 0.42-0.92) or not (RR, 0.43; 95% CI, 0.28-0.67). CONCLUSION Rectal NSAIDs are effective in the prevention of PEP in unselected patients.

Abstract
Background Fecal microbiota transplantation (FMT) has been recognized as a novel treatment for ulcerative colitis (UC). However, its efficacy and safety remain unclear. Objective We conducted this systematic review to assess the efficacy and safety of FMT in UC. Data Sources PubMed, EMBASE, Cochrane Central, Web of Science Core Collection, and three other Chinese databases were searched for reports of FMT in UC with clear outcomes. Data Extraction and Synthesis We estimated pooled rates [with 95% confidence interval (CI)] of clinical remission among 15 cohort studies and clinical response among 16 cohort studies. Results Twenty five studies (2 randomized controlled trials, 15 cohort studies, and 8 case studies) with 234 UC patients were included. Overall, 41.58% (84/202) patients achieved clinical remission (CR) and 65.28% (126/193) achieved clinical response. Among the cohort studies, the pooled estimate of patients who achieved CR and clinical response were 40.5% (95% CI 24.7%-58.7%), and 66.1% (95% CI 43.7%-83.0%). Most adverse events were slight and self-resolving. The analyses of gut microbiota in 7 studies showed that FMT could increase microbiota diversity and richness, similarity, and certain change of bacterial composition. Conclusion FMT provides a promising effect for UC with few adverse events. Successful FMT may be associated with an increase in microbiota diversity and richness, similarity, and certain change of bacterial composition.

Abstract
Chronic growth hormone (GH) therapy has been shown to cause insulin resistance, but the mechanism remains unknown. PTEN, a tumor suppressor gene, is a major negative regulator of insulin signaling. In this study, we explored the effect of chronic GH on insulin signaling in the context of PTEN function. Balb/c healthy mice were given recombinant human or bovine GH intraperitoneally for 3 weeks. We found that phosphorylation of Akt was significantly decreased in chronic GH group and the expression of PTEN was significantly increased. We further examined this effect in the streptozotocin-induced Type I diabetic mouse model, in which endogenous insulin secretion was disrupted. Insulin/PI3K/Akt signaling was impaired. However, different from the observation in healthy mice, the expression of PTEN did not increase. Similarly, PTEN expression did not significantly increase in chronic GH-treated mice with hypoinsulinemia induced by prolonged fasting. We conducted in-vitro experiments in HepG2 cells to validate our in-vivo findings. Long-term exposure to GH caused similar resistance of insulin/PI3K/Akt signaling in HepG2 cells; and over-expression of PTEN enhanced the impairment of insulin signaling. On the other hand, disabling the PTEN gene by transfecting the mutant PTEN construct C124S or siPTEN, disrupted the chronic GH induced insulin resistance. Our data demonstrate that PTEN plays an important role in chronic-GH-induced insulin resistance. These findings may have implication in other pathological insulin resistance.

Abstract
BACKGROUND AND AIM Endoscopic sphincterotomy (EST) alone and EST combined with balloon dilation (ESBD) are important endoscopic techniques for stone extraction. We were to conduct a meta-analysis to compare the efficacy and safety of ESBD and EST. METHODS Meta-analysis was performed respectively on randomized controlled trials (RCTs) and nonrandomized studies comparing the efficacy and safety of ESBD and EST. RESULTS The results of three RCTs showed that stone removal in first session (relative risk [RR] 1.01, 0.92-1.11, P=0.85) and the utility of endoscopic mechanical lithotripsy (EML) (RR 0.78, 0.49-1.23, P=0.29) were equivalent between ESBD and EST. ESBD has equivalent complications (RR 0.61, 0.17-2.25, P=0.46) and post-ERCP pancreatitis (Peto odds ratio [OR] 1.11, 0.37-3.35, P=0.86), but less bleeding (Peto OR 0.10, 0.03-0.30, P<0.0001). The analysis of six retrospective studies suggested higher initial success in stone removal (RR 1.11, 1.02-1.20, P=0.01) and less EML (RR 0.32, 0.22-0.46, P<0.00001) in ESBD group. Less complications (RR 0.60, 0.44-0.83, P=0.02) happened in ESBD group, but equivalent post-ERCP pancreatitis (Peto OR 0.65, 0.37-1.15, P=0.14) and bleeding (Peto OR 0.60, 0.29-1.26, P=0.18). For patients with stones ≥ 15 mm, ESBD required less EML (RR 0.35, 0.24-0.51, P<0.00001) and caused fewer complications (RR 0.67, 0.38-0.92, P=0.02). CONCLUSIONS ESBD is feasible for the treatment of choledocholithiasis without increased risk of complications, causing less bleeding. However, it warrants more clinical trials to compare the efficacy and safety of ESBD and EST.

Abstract
Several randomized controlled trials (RCT) have shown that water infusion in lieu of air insufflation reduces sedation rate and pain score and increases cecal intubation rate in colonoscopy. The aim of the present study was to confirm the beneficial effects of the water intubation method over the air method. Electronic databases were searched to identify RCT reporting colonoscopy detection using the water method. The pooled data of sedation rate, pain score and other procedure-related outcomes were analyzed. Then, 15 full-text articles were selected and assessed. Nine trials with high-quality scores were enrolled into this meta-analysis including a total of 1414 participants. Pooled odds ratio (OR) of sedation rate was 0.392 (95% confidence interval (CI): 0.288-0.533, P = 0.000). Pooled weighted mean difference (WMD) of pain score was -1.543 (95% CI: -2.107--1.069,P = 0.000). Pooled OR of cecal intubation rate was 1.90 (95% CI: 1.29-2.82, P = 0.001). Pooled OR of polyp detection rate and adenoma detection rate were 0.805 (95% CI: 0.606-1.069, P = 0.134) and 0.913 (95% CI: 0.681-1.223, P = 0.168), respectively. Pooled WMD of cecal intubation time was 0.701 (95% CI: -0.486-1.889, P = 0.247). This meta-analysis confirmed that the water method significantly reduced sedation rate and degree of pain without decreasing cecal intubation rate and disease detection rate and without requiring more cecal intubation time, suggesting that the novel water method is better than the conventional air method in colonoscopy detection.

Abstract
BACKGROUND AND AIM Endoscopic papillary balloon dilatation (EPBD) and endoscopic sphincterotomy (EST) are two common nonsurgical treatments endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis. The aim of this study was to compare the efficacy and safety of EPBD and EST in the treatment for choledocholithiasis, confining the analysis to work reported in the last decade. METHODS The rate of overall postoperative complications was chosen as the primary outcome, and 10 other outcomes were secondary outcomes. Relative risk (RR) or Peto odds ratio (OR) were computed as the measures of pooled effects. We planned sensitivity analyses a priori for examining the change in robustness of the sensitivity to excluding studies with some inappropriate objects, technique defects or without full-text acquisition. RESULTS For complete stone removal, EPBD was similar to EST (95% vs. 96%, P = 0.36) and overall postoperative complications (14.0% vs. 11.7%, P = 0.53). The incidence of post-ERCP cholangitis (2.5% vs. 1.8%, P = 0.40), basket impaction (0.9% vs. 0%, P = 0.16) and perforation (0.0% vs. 0.4%, P = 0.17) were equivalent between EPBD and EST. On the other hand, EPBD caused more post-ERCP pancreatitis (PEP) (9.4% vs. 3.3%, P < 0.00001), but less hemorrhage (0.1% vs. 4.2%, P < 0.00001). People undergoing EPBD required more use of endoscopic mechanical lithotripsy (35.0% vs. 26.2%, P = 0.0004). The results of sensitivity analyses showed no substantial change. CONCLUSION EPBD is comparable to EST for stone extraction, though it requires more endoscopic mechanical lithotripsy (EML). EPBD may outweigh EST for patients with coagulopathy; however, it may cause more PEP.
