Background To assess the long-term safety and efficacy of monotherapy with a single fresh fecal microbiota transplant (FMT) for recurrent ulcerative colitis (UC). Results Twenty-six eligible patients were enrolled, and 6 patients were excluded. Ultimately, 20 patients were randomized to the FMT group (n = 10) and the control group (n = 10); 80% were females (F/M = 16/4), the mean age was 48 ± 14 years, and the mean duration was 6.4 ± 8.2 years. The mean length of post-FMT follow-up was 19.1 ± 10.1 months (6–38). No statistically significant differences in baseline demographic or clinical characteristics were found between the groups. Ninety percent of patients in the FMT group and 50% of patients in the control group met the primary endpoint at week 8. The Mayo score was significantly decreased compared with that of the control group (n = 10) when reassessed at week 4 (P = 0.001) and week 8 (P = 0.019) after FMT; there was no significant difference 6 months after treatment. The median remission time was 24 months (95% CI 68.26–131.7%) in both the FMT (range 6–38 months) and control groups (range 7–35 months), with no significant difference (P = 0.895). Participants tolerated FMT treatment, and no adverse events occurred during long-term follow-up, with one treatment-related significant adverse event (EBV infection) occurring within 2 weeks after FMT. Stool microbiota composition analysis indicated improved gut microbiota diversity after FMT, with expansion of stool-donor taxa. Bacteroidetes, Firmicutes and Proteobacteria were the dominant bacterial phyla of the gut microbiota in active UC patients. The relative abundance of Bacteroidetes decreased and that of Proteobacteria increased significantly in active UC patients compared with donors, while Firmicutes showed no significant changes. A single fresh FMT could effectively reconstruct the gut microbiota composition in patients with active UC and maintain stability, with increased Bacteroidetes and decreased Proteobacteria abundance. FMT significantly reduced the relative abundance of Escherichia and increased the relative abundance of Prevotella at the genus level. Pyruvate metabolism, glyoxylate and dicarboxylate metabolism, and pantothenate and CoA biosynthesis showed significant differences after transplantation. Conclusions Monotherapy with a single fresh FMT is an effective and safe strategy to induce long-term remission without drugs in patients with active UC and may be an alternative induction therapy for recurrent UC or even primary UC.
Background To compare the efficacy of three types of palliative therapy for advanced hepatocellular carcinoma (HCC), including transarterial chemoembolisation (TACE) monotherapy, sorafenib alone and their combination. Methods The databases of PubMed, Embase and Cochrane Library were retrieved. The odds ratio (OR) with its 95% confidence interval (CI) was used to investigate the binary variables, and the standardised mean difference (SMD) with its 95% CI was employed to evaluate the continuous variables. All statistical tests were performed by using Stata/SE, version 12.0. Results Thirty-one clinical studies, containing 5125 unique cases of patients with advanced HCC, were included. There were significant improvements in overall survival (OS) (pooled SMD = 2.54; 95% CI 1.74–3.34) and time to progression (TTP) (pooled SMD = 2.49; 95% CI 0.87–4.12) of the patients after receiving the combination therapy of TACE and sorafenib, compared to TACE monotherapy, and the OS in the combined treatment cohort was also longer than that in the sorafenib-alone cohort (pooled SMD = 2.92; 95% CI 1.72–4.13). The combination therapy group in comparison to the TACE group benefited a significantly increased overall response rate (ORR) (pooled OR = 2.61; 95% CI 1.43–4.77), 1-year (pooled OR = 2.96; 95% CI 1.71–5.14) and 2-year (pooled OR = 1.64; 95% CI 1.18–2.28) survival rates and reduced disease progression rate (DPR) (pooled OR = 0.47; 95% CI 0.33–0.68); in parallel, the ORR in the group was also significantly higher than that in the sorafenib-alone group (pooled OR = 3.62; 95% CI 1.28–10.22), although without a difference in the DPR (pooled OR = 0.28; 95% CI 0.05–1.48). In addition, we discovered that the 1-year (pooled OR = 1.39; 95% CI 0.84–2.29) and 2-year (pooled OR = 1.70; 95% CI 0.69–4.18) survival rates in the TACE monotherapy cohort were not significantly different to those in the sorafenib-alone cohort. Conclusion The combination therapy is more effective than monotherapy in improving the prognostic outcomes of patients with advanced HCC. Therefore, we recommend it as the preferred treatment intervention for those patients.

BackgroundThe topic of in ammatory bowel disease (IBD) has attracted more and more attentions. Accumulating evidence suggests that exposure to air pollutants is associated with IBD, yet the results are inconsistent and study about daily exposure is few. This study evaluated the association between daily air pollution and IBD in Hefei, China. MethodsDaily IBD admission data were obtained from two hospitals in Hefei from January 1, 2019 to December 31, 2019. Daily concentrations of major air pollutants were provided by the Hefei Environmental Protection Bureau. Meteorological data were collected from China Meteorological Data Network.Distributed lag nonlinear model (DLNM) considering both the lag effects of exposure factors and nonlinear relationship of exposure-reaction was used to assess the effect of daily air pollutants exposure on IBD admission. ResultsDuring the study period, totally 886 cases of IBD were recruited, including 313 cases of ulcerative colitis (UC) and 573 cases of Crohn's disease (CD). The ndings showed PM 2.5 , O 3 and CO exposure signi cantly increased the risk of IBD. Mean concentrations of PM 2.5 , O 3 and CO in Hefei were 43.85ug/m³, 100.78ug/m³, and 0.76mg/m³, respectively. Each increase of 10mg/m³ in PM 2.5 / O 3 and 0.1mg/m³ in CO increased the risk of IBD. The strongest effects of these three pollutants on IBD were observed in lag2-lag3 (RR = 1.037, 95% CI: 1.005-1.070%), lag3 (RR = 1.020, 95% CI: 1.002-1.038%) and lag2 (RR = 1.036, 95% CI: 1.003-1.071%), respectively. In warm seasons, PM 2.5 , O 3 and CO had a stronger effect increased the risk of IBD, which were observed in lag2 (RR = 1.
Ginkgo biloba extract (GBE) is a plant extract obtained from the leaves of G biloba tree. The aim of this study was to evaluate the clinicopathologic characteristics and therapeutic effects of GBE on ischemic colitis (IC).Forty-seven patients with IC were divided as GBE group (n = 30) and routine group (n = 17). The routine group was given routine therapy, and the GBE group was given routine therapies plus GBE intravenous injection. Clinicopathologic characteristics, endoscopy findings, serum antioxidant enzymes, and inflammatory mediators were evaluated.About 89.3% initial symptom was acute-onset abdominal cramping and abdominal pain followed with hematochezia. The lesions were mainly located in sigmoid colon (80.8%). Serum level of superoxide dismutase (SOD) in patients with IC was significantly decreased (P < .05), while methane dicarboxylic aldehyde (MDA), tumor necrosis factor alpha (TNF-α), and interleukin-6 (IL-6) levels were significantly increased (P < .05). However, serum procalcitonin (PCT) level showed no significant change. Treatment of GBE resulted in quick remittance of abdominal pain and hematochezia, and significant attenuation of colon macroscopic and histologic damage in all patients. Furthermore, the treatment also significantly increased SOD levels, decreased MDA, TNF-α, and IL-6 levels (P < .05).Acute-onset abdominal cramping or abdominal pain followed with hematochezia was the mainly initial symptom of IC, and sigmoid and descending colons were the common vulnerable sites. GBE exerted a beneficial effect on IC with faster symptom relief and better mucosal healing, possibly through scavenging oxidative-free radicals and downregulating inflammatory mediators. GBE may be a promising candidate for protection against IC.
