Dietary oxidized cholesterol causes mucus barrier thinner via decreasing Muc2 expression in the proximal colon and increasing the abundance of mucus-degrading bacteria

引用

Food Science and Human Wellness 2024年

作者： Chi Yan Shou-He huang Zi-Xing Chen hua-Fang Ding Zhen-Yu Chen School of Life Sciences Faculty of Science The Chinese University of Hong Kong

Oxidized cholesterol (OXC) is a harmful dietary substance. Although the consumption of OXC has been associated with colonic inflammation， related underlying mechanisms are still limited. We evaluated the influence of dietary OXC on gut health and ecology by applying the murine model. Results showed that the thickness of the mucus layer was significantly reduced in healthy mice treated with OXC. Short-term intake of OXC did not influence the expression of pro-inflammatory factors in healthy mice but it induced the decrease of Muc2 expression in the proximal colon， accompanied by an increase in the abundance of two mucus-degrading bacteria， namely A. muciniphila and B. acidifaciens. Consistently， oral exposure of OXC promoted mucus barrier erosion in DSS-induced colitis mice and facilitated bacteria infiltration in the colon. The adverse effect of OXC on mucus layer disappeared in antibiotics-treated healthy mice， suggesting that the damaging effect of OXC on the gut mucus layer was not direct and instead was mediated by causing microbiota dysbiosis. Finally， the impact of OXC on the mucus layer and colitis was partly alleviated by green tea catechins. These studies demonstrated that the OXC-induced mucus barrier damage was mainly induced by the dysregulation of gut microbiota at least in this mouse model.

Diagnose and treatment for Type D congenital esophageal atresia with tracheoesophageal fistula

Importance: Type D esophageal atresia (EA) with tracheoesophageal fistula (TEF) is characterized by EA with both proximal and distal TEFs. It is a rare congenital anomaly with a very low ***: To investigate diagnostic and treatment strategies for this rare ***: We retrospectively reviewed the clinicopathological features of patients with EA/TEF treated at our institution between January 2007 and September ***: Among 386 patients with EA/TEF, 14 (3.6%) had type D EA/TEF. Only two patients were diagnosed with proximal TEF preoperatively. Seven patients were diagnosed intraoperatively. Five patients were missed for diagnosis during the initial surgery but was later confirmed by bronchoscopy. During the neonatal period, seven patients underwent a one-stage repair of proximal and distal TEF via thoracoscopy or thoracotomy. Due to missed diagnosis and other reasons, the other 7 patients underwent two-stage surgery for repair of the proximal TEF, including cervical incision and thoracoscopy. Ten of the 14 patients experienced postoperative complications including anastomotic leakage, pneumothorax, esophageal stricture, and recurrence. Patients who underwent one-stage repair of distal and proximal TEF during the neonatal period showed a higher incidence of anastomotic leak (4/7). In contrast, only one of seven patients with two-stage repair of the proximal TEF developed an anastomotic ***: Type D EA/TEF is a rare condition, and proximal TEFs are easily missed. Bronchoscopy may aim to diagnose and determine the correct surgical approach. A cervical approach may be more suitable for repairing the proximal TEF.

Background: Primary non-function(PNF) and early allograft failure(EAF) after liver transplantation(LT) seriously affect patient outcomes. In clinical practice, effective prognostic tools for early identifying recipients at high risk of PNF and EAF were urgently needed. Recently, the Model for Early Allograft Function(MEAF), PNF score by King's College(King-PNF) and Balance-and-Risk-Lactate(BAR-Lac) score were developed to assess the risks of PNF and EAF. This study aimed to externally validate and compare the prognostic performance of these three scores for predicting PNF and EAF. Methods: A retrospective study included 720 patients with primary LT between January 2015 and December 2020. MEAF, King-PNF and BAR-Lac scores were compared using receiver operating characteristic(ROC) and the net reclassification improvement(NRI) and integrated discrimination improvement(IDI) analyses. Results: Of all 720 patients, 28(3.9%) developed PNF and 67(9.3%) developed EAF in 3 months. The overall early allograft dysfunction(EAD) rate was 39.0%. The 3-month patient mortality was 8.6% while 1-year graft-failure-free survival was 89.2%. The median MEAF, King-PNF and BAR-Lac scores were 5.0(3.5–6.3),-2.1(-2.6 to-1.2), and 5.0(2.0–11.0), respectively. For predicting PNF, MEAF and King-PNF scores had excellent area under curves(AUCs) of 0.872 and 0.891, superior to BAR-Lac(AUC = 0.830). The NRI and IDI analyses confirmed that King-PNF score had the best performance in predicting PNF while MEAF served as a better predictor of EAD. The EAF risk curve and 1-year graft-failure-free survival curve showed that King-PNF was superior to MEAF and BAR-Lac scores for stratifying the risk of EAF. Conclusions: MEAF, King-PNF and BAR-Lac were validated as practical and effective risk assessment tools of PNF. King-PNF score outperformed MEAF and BAR-Lac in predicting PNF and EAF within 6 months. BAR-Lac score had a huge advantage in the prediction for PNF without post-transplant variables. Proper use
