An increase of Escherichia-Shigella was previously reported in acute necrotizing pancreatitis (ANP). We investigated whether Escherichia coli MG1655, an commensal organism, increased intestinal injury and aggravated ANP rats. induced by retrograde injection 3.5% sodium taurocholate into the biliopancreatic duct. Using gut microbiota-depleted rats, we demonstrated that microbiota involved pancreatic barrier dysfunction ANP. 16S rRNA gene sequencing quantitative PCR, found dysbiosis a significant E.

Weaning is considered to be one of the most critical periods in pig production, which related economic benefits farms. However, actual many piglets are often subjected weaning stress due sudden separation from sow, changes diet and living environment, other social challenges. causes morphology function small intestine piglets, disrupts digestion absorption capacity, destroys intestinal barrier function, ultimately leads reduced feed intake, increased diarrhea rate, growth retardation. Therefore, correctly understanding effects on health have important guiding significance for nutritional regulation injury caused by stress. In this review, we mainly reviewed aspects development, thereby providing a theoretical basis strategies alleviate mammals future studies.

Severe acute pancreatitis (SAP), a serious inflammatory disease of the pancreas, can easily lead to systemic response syndrome (SIRS) and multiple organ dysfunction syndromes (MODS). Acute lung injury (ALI) is one most complications SAP. However, specific pathogenesis SAP-associated ALI not fully understood. Crosstalk multi-mechanisms involving pancreatic necrosis, bacteremia, intestinal barrier failure, activation cascades diffuse alveolar damage main reason for unclear pathological mechanism ALI. According previous research on in our laboratory theories put forward by other scholars, we propose that complex pattern based "pancreas-intestine-inflammation/endotoxin-lung (P-I-I/E-L) pathway".

Background Probiotics play a vital role in treating immune and inflammatory diseases by improving intestinal barrier function; however, comprehensive evaluation is missing. The present study aimed to explore the impact of probiotics on related function, inflammation, microbiota composition. A systematic review meta-analyses were conducted. Methods Four major databases (PubMed, Science Citation Index Expanded, CENTRAL, Embase) thoroughly searched. Weighted mean differences calculated for continuous outcomes with corresponding 95% confidence intervals (CIs), heterogeneity among studies was evaluated utilizing I2 statistic (Chi-Square test), data pooled using random effects meta-analyses. Results Meta-analysis from total 26 RCTs (n = 1891) indicated that significantly improved gut function measured levels TER (MD, 5.27, CI, 3.82 6.72, P < 0.00001), serum zonulin (SMD, -1.58, -2.49 -0.66, 0.0007), endotoxin -3.20, -5.41 -0.98, 0.005), LPS -0.47, -0.85 -0.09, 0.02). Furthermore, probiotic groups demonstrated better efficacy over control reducing factors, including CRP, TNF-α, IL-6. can also modulate structure boosting enrichment Bifidobacterium Lactobacillus.

Mushroom polysaccharides are recognized as "biological response modifiers". Besides several bioactivities, a growing interest in their prebiotic potential has been raised due to the gut microbiota modulation potential. This review comprehensively summarizes mushroom polysaccharides' biological properties, structure-function relationship, and underlying mechanisms. It provides recent overview of key findings field (2018–2024). Key limitations on correlation discussed. Although most studies focus β-glucans or extracts, α-glucans chitin have gained interest. Prebiotic capacity associated with chitin, while antimicrobial wound healing is attributed chitin. However, further research utmost importance. Human fecal fermentation reported approach assess potential, indicating impacts intestinal biological, mechanical, chemical immunological barriers. Gut dysbiosis directly connected intestinal, cardiovascular, metabolic, neurological diseases. Concerning modulation, animal experiments suggested proinflammatory cytokines reduction redox balance re-establishment. Most literature focused anticancer immunomodulatory anti-inflammatory, antimicrobial, antiviral, antidiabetic, hypocholesterolemic, antilipidemic, antioxidant, neuroprotective properties A significant gaps directions synergistic effects, mechanisms, correlation, clinical trials scientific data also given.

Acute pancreatitis (AP) is an inflammatory disease that can progress to severe acute (SAP), which increases the risk of death. AP characterized by inappropriate activation trypsinogen, infiltration cells, and destruction secretory cells. Other contributing factors may include calcium (Ca2+) overload, mitochondrial dysfunction, impaired autophagy, endoplasmic reticulum (ER) stress. In addition, exosomes are also associated with pathophysiological processes many human diseases play a biological role in AP. However, pathogenic mechanism has not been fully elucidated needs be further explored inform treatment. Recently, treatment guidelines have changed; minimally invasive therapy advocated more as core multidisciplinary participation "step-up" approach. The surgical procedures gradually changed from open surgery primarily includes percutaneous catheter drainage (PCD), endoscopy, small incision surgery, video-assisted surgery. current for management updated revised aspects. type fluid used, timing, volume, speed administration resuscitation controversial. timing nutritional support prophylactic antibiotic therapy, well or endoscopic intervention, complications still uncertainties could negatively impact prognosis patients' quality life.
