Front Microbiol 2024; 15:1407091. [PMID: 38855764 PMCID: PMC11157515 DOI: 10.3389/fmicb.2024.1407091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2024] [Accepted: 05/07/2024] [Indexed: 06/11/2024] Open
Abstract
Objective The aim of the study is to investigate the function and mechanism of Zinc Gluconate (ZG) on intestinal mucosal barrier damage in antibiotics and Lipopolysaccharide (LPS)-induced mice. Methods We established a composite mouse model by inducing intestinal mucosal barrier damage using antibiotics and LPS. The animals were divided into five groups: Control (normal and model) and experimental (low, medium, and high-dose ZG treatments). We evaluated the intestinal mucosal barrier using various methods, including monitoring body weight and fecal changes, assessing pathological damage and ultrastructure of the mouse ileum, analyzing expression levels of tight junction (TJ)-related proteins and genes, confirming the TLR4/NF-κB signaling pathway, and examining the structure of the intestinal flora. Results In mice, the dual induction of antibiotics and LPS led to weight loss, fecal abnormalities, disruption of ileocecal mucosal structure, increased intestinal barrier permeability, and disorganization of the microbiota structure. ZG restored body weight, alleviated diarrheal symptoms and pathological damage, and maintained the structural integrity of intestinal epithelial cells (IECs). Additionally, ZG reduced intestinal mucosal permeability by upregulating TJ-associated proteins (ZO-1, Occludin, Claudin-1, and JAM-A) and downregulating MLCK, thereby repairing intestinal mucosal barrier damage induced by dual induction of antibiotics and LPS. Moreover, ZG suppressed the TLR4/NF-κB signaling pathway, demonstrating anti-inflammatory properties and preserving barrier integrity. Furthermore, ZG restored gut microbiota diversity and richness, evidenced by increased Shannon and Observed features indices, and decreased Simpson's index. ZG also modulated the relative abundance of beneficial human gut bacteria (Bacteroidetes, Firmicutes, Verrucomicrobia, Parabacteroides, Lactobacillus, and Akkermansia) and harmful bacteria (Proteobacteria and Enterobacter), repairing the damage induced by dual administration of antibiotics and LPS. Conclusion ZG attenuates the dual induction of antibiotics and LPS-induced intestinal barrier damage and also protects the intestinal barrier function in mice.

Mannanase improves the growth performance of broilers by alleviating inflammation of the intestinal epithelium and improving intestinal microbiota. ANIMAL NUTRITION (ZHONGGUO XU MU SHOU YI XUE HUI) 2024; 16:376-394. [PMID: 38371477 PMCID: PMC10874740 DOI: 10.1016/j.aninu.2023.06.017] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 05/26/2023] [Accepted: 06/10/2023] [Indexed: 02/20/2024]
Abstract
This experiment aimed to discuss and reveal the effect and mechanism of mannanase on intestinal inflammation in broilers triggered by a soybean meal diet. In this experiment, 384 Arbor Acres broilers at 1 d old were randomly divided into 3 treatment groups. The broilers were fed a corn-soybean meal basal diet, a low-energy diet (metabolizable energy reduced by 50 kcal/kg), and a low-energy diet supplemented with 100 mg/kg mannanase for 42 d. The low-energy diet increased feed conversion ratio from 0 to 42 d, reduced ileal villus height and villus height-to-crypt depth ratio and upregulated the expression of nuclear factor kappa B (NF-κB) in the ileum (P < 0.05). It also reduced cecal short-chain fatty acids (SCFA), such as acetic acid (P < 0.05). Compared with low-energy diets, the addition of mannanase increased body weight at 42 d, promoted the digestibility of nutrients, and maintained the morphology and integrity of the intestinal epithelium of broilers (P < 0.05). In addition, mannanase upregulated the expression of claudin-1 (CLDN1) and zonula occludens-1 (ZO-1) in the jejunum at 21 d, downregulated the expression of ileal NF-κB, and increased the content of isobutyric acid in the cecum of broilers (P < 0.05). The results for the ileal microbiota showed that a low-energy diet led to a decrease in the relative abundance of Lactobacillus reuteri in the ileum of broilers. The addition of mannanase increased the relative abundance of Lactobacillus-KC45b and Lactobacillus johnsonii in broilers. Furthermore, a low-energy diet reduced the relative abundance of Butyricicoccus in the intestine of broilers and inhibited oxidative phosphorylation and phosphoinositol metabolism. Mannanase increased the relative abundance of Odoribacter, promoted energy metabolism and N-glycan biosynthesis, and increased the activities of GH3 and GH18. It is concluded that mannanase could improve the growth performance of broilers by reducing the expression of NF-κB in the ileum, increasing the production of SCFA in the cecum, suppressing intestinal inflammation, balancing the intestinal microbiota, reducing damage to the intestinal barrier, and improving the efficiency of nutrient utilization to alleviate the adverse effects caused by the decrease in dietary energy level.

Abstract
BACKGROUND Severe acute pancreatitis (SAP), a condition with rapid onset, critical condition and unsatisfactory prognosis, poses a certain threat to human health, warranting optimization of relevant treatment plans to improve treatment efficacy. AIM To evaluate the efficacy and safety of computerized tomography-guided therapeutic percutaneous puncture catheter drainage (CT-TPPCD) combined with somatostatin (SS) in the treatment of SAP. METHODS Forty-two SAP patients admitted to The Second Affiliated Hospital of Fujian Medical University from June 2020 to June 2023 were selected. On the basis of routine treatment, 20 patients received SS therapy (control group) and 22 patients were given CT-TPPCD plus SS intervention (research group). The efficacy, safety (pancreatic fistula, intra-abdominal hemorrhage, sepsis, and organ dysfunction syndrome), abdominal bloating and pain relief time, bowel recovery time, hospital stay, inflammatory indicators (C-reactive protein, interleukin-6, and procalcitonin), and Acute Physiology and Chronic Health Evaluation (APACHE) II score of both groups were evaluated for comparison. RESULTS Compared with the control group, the research group had a markedly higher total effective rate, faster abdominal bloating and pain relief and bowel recovery, shorter hospital length of stay, fewer complications, and lower posttreatment inflammatory indices and APACHE-II scores. CONCLUSION CT-TPPCD in combination with SS is effective for SAP patients, which can reduce complications, accelerate symptom resolution, inhibit inflammation, and improve patient condition, with promising prospects for clinical promotion.

Abstract
Irritable bowel syndrome (IBS) is characterized by visceral pain, impaired intestinal barrier and a disorder of the microbiota. DXL-A-24 has analgesic and anti-inflammatory effects by inhibiting neuropeptides and inflammatory factors. In this study, we used chronic unpredictable mild stress (CUMS) induced IBS model, to assess the action of DXL-A-24 on visceral hypersensitivity, barrier function and microbiota. Visceral sensation was assessed by colorectal distension in a model of IBS. The expressions of substance P (SP) and calcitonin gene-related peptide (CGRP) were detected by immunohistochemistry and western blot, the contents of diamine oxidase (DAO) and D-lactic acid were detected by ELISA, and 16S rRNA to detect the diversity of gut microbiota. CUMS reduced visceral pain threshold and increased colonic permeability of rats. DXL-A-24 for 28 days inhibited these changes. DXL-A-24 also decreased the expression of SP, CGRP in colon and D-LA, DAO in serum. Besides, DXL-A-24 increased the richness and diversity of intestinal microbiota. In conclusions, DXL-A-24 reduced visceral sensitivity, improved intestinal barrier and regulated gut microbiota in rats with IBS.

Abstract
Aeromonas hydrophila can pose a great threat to fish survival. In this study, we investigated the differential immune and redox response in gut-liver axis of hybrid fish (WR) undergoing gut infection. WR anally intubated with A. hydrophila showed severe midgut injury with decreased length-to-width ratios of villi along with GC hyperplasia and enhanced antioxidant activities, but expression profiles of cytokines, chemokines, antibacterial molecules, redox sensors and tight junction proteins decreased dramatically. In contrast, immune-related gene expressions and antioxidant activities increased significantly in liver of WR following gut infection with A. hydrophila. These results highlighted the differential immune regulation and redox balance in gut-liver axis response to bacterial infection.

Abstract
Acute pancreatitis (AP) causes intestinal barrier damage, resulting in systemic inflammatory response syndrome (SIRS) or multiple organ dysfunction syndrome (MODS), which are important factors affecting AP severity and mortality. Here, we studied the mechanism of miR-122 in regulating intestinal barrier function in AP. AP rat model was constructed via intraperitoneal injection of ketamine, and primary intestinal epithelial cells were isolated from rats for in vitro studies. HE staining was used to assess pathological alterations of pancreas and intestines tissues. Inflammatory factors were detected by ELISA assay. qRT-PCR and WB were used to detect the expressions of miR-122 and occluding, respectively. Then dual-luciferase reporter assay, intestinal permeability test, and cell permeability were performed in vivo and in vitro to probe the molecular mechanism of miR-122 in regulating intestinal barrier function in AP. The expression of miR-122 was upregulated in AP rats, while the expression of occludin was downregulated, and the intestinal permeability was increased in AP rats and primary intestinal epithelial cells isolated from rats. Inhibition of miR-122 regulated intestinal barrier function through mediating occludin expression. miR-122 regulated intestinal barrier function to affect AP through mediating occludin expression in vivo. These results provided evidence that miR-122 overexpression impaired intestinal barrier function via regulation of occludin expression, thus promoting AP progression.

Abstract
BACKGROUND The pathogenesis of gastroesophageal reflux disease (GERD) is closely associated with the intestinal bacteria composition and their metabolites.
AIM To investigate whether washed microbiota transplantation (WMT) improves symptoms of nonerosive reflux disease (NERD) with proton pump inhibitor (PPI) dependency.
METHODS Patients with recurrent NERD and PPI dependency at the First Affiliated Hospital of Guangdong Pharmaceutical University from 2017 to 2018 were included and divided into a WMT or PPI group treated with PPI with/without WMT. The endpoint was NERD symptom frequency evaluated 1 mo after WMT using reflux disease questionnaire (RDQ) and GERD questionnaire (GERDQ) scores, remission time, PPI dose, and the examination of intestinal mucosal barrier function.
RESULTS In the WMT (n = 15) and PPI (n = 12) groups, the total remission rate at 1 mo after treatment was 93.3% vs 41.7%. Compared with the PPI group, the WMT group showed better results in GERDQ (P = 0.004) and RDQ (P = 0.003) and in remission months (8 vs 2, P = 0.002). The PPI dose was reduced to some extent for 80% of patients in the WMT group and 33.3% in the PPI group. In 24 patients, intestinal mucosal barrier function was examined before treatment, and changes in the degree of damage were observed in 13 of these patients after treatment. Only one of the 15 patients had minor side effects, including a mushy stool two or three times a day, which resolved on their own after 1 wk.
CONCLUSION This study is the first to demonstrate that WMT may be safe and effective for relieving NERD symptoms and reducing PPI dependency and recurrence.

Abstract
Severe acute pancreatitis (SAP), which is characterized by acute onset and high mortality, is complicated with systemic inflammatory response syndrome. This study investigated the molecular mechanism underlying SAP-induced intestinal mucosal barrier injury. SAP was established in rats by retrograde injection of sodium taurocholate (STC) into biliopancreatic duct. Transfection of miR-99a mimic was conducted 24 h before the SAP establishment. Histological properties of pancreatic and intestinal tissues were observed by hematoxylin-eosin staining. The serum levels of interleukin (IL)-1β, tumor necrosis factor (TNF)-α, procalcitonin (PCT), endotoxin (ET), and diamine oxidase (DAO) were measured by enzyme-linked immunosorbent assay. The expressions of miR-99a, NADPH oxidase (NOX)4, zonula occludens (ZO)-1, occludin, and claudin-1 in pancreatic and the intestinal tissue were determined by quantitative reverse transcription polymerase chain reaction or Western blot. STC injection damaged pancreatic and intestinal tissues of the rats. During the model construction, the serum levels of IL-1β, TNF-α, PCT, ET, and DAO were increased, whereas miR-99a expression in pancreatic and intestinal tissues of the rats was decreased. miR-99a mimic alleviated SAP-induced histological abnormality of pancreatic and intestinal tissues; moreover, it reversed the serum levels of IL-1β, TNF-α, PCT, ET, and DAO increased by SAP, decreased SAP-increased NOX4 expression and increased the expressions of ZO-1, occludin, and claudin-1 previously decreased by SAP in pancreatic and the intestinal tissues. Thus, overexpressed miR-99a could alleviate intestinal mucosal barrier injury in rats with SAP.

Abstract
Studies on the possible alternative supplements to breastmilk are gaining research interests. Although milk from cow, goat, and mare is nutritious, its effects on the relationship between the immune system, metabolites, and gut microbiota remain unclear. This study aimed to comprehensively evaluate the effects of cow, goat, and mare milk on the immune system, metabolites, and gut microbiota of mice colonized by healthy infant feces using human milk as a standard. We examined the serum biochemistry parameters, immunity indicators, T cells, gut microbiota abundance, and metabolites. Results showed that the impact of human milk on alanine transaminase, glutamic oxaloacetic transaminase, total protein, globulin, and glucose values was different from the cow, goat, and mare milk types. The effects of mare milk on the percentage of CD4+ T, Th1, Th2, Th17, and Treg cells, and the levels of IL-2, IL-4, sIgA, and d-lactic acid in the serum of the human microbiota-associated mice were comparable to those of human milk. Also, bacterial 16S rRNA gene sequence analysis revealed that human milk enriched the relative abundance of Akkermansia and Bacteroides, cow milk increased the relative abundance of Lactobacillus, goat milk increased the relative abundance of Escherichia-Shigella, and mare milk improved the relative abundance of Klebsiella. Besides, mare milk was similar to human milk in the concentration of the metabolites we analyzed. Our findings suggest that mare milk can positively modulate the gut microbiota and immunity status of infants and thus could be a possible replacement for human milk.

Abstract
An enterogenic infection occurs when intestinal mucosal disruption is followed by the invasion of intestinal bacteria into the blood and distant organs, which can result in severe diseases or even death. Our previous study using Rhesus monkeys as an in vivo model revealed that methamphetamine (MA) induced intestinal mucosal barrier damage, which poses a high risk of enterogenic infection. However, how methamphetamine causes intestinal mucosal barrier damage remains largely unknown. In this study, we employed an in vitro model, and found that MA treatment could inhibit the expression of miR-181c, which directly targets and regulates TNF-α, and ultimately induces apoptosis and damages the intestinal barrier. Moreover, we measured TNF-α serum levels as well as the intestinal mucosal barrier damage indicators (diamine oxidase, d-lactic acid, and exotoxin) and found that their levels were significantly higher in MA-dependents than in healthy controls (P < 0.001). To the best of our knowledge, this is the first report evidencing that miR-181c is involved in MA-induced intestinal barrier injury via TNF-α regulation, which introduces novel potential therapeutic targets for MA-dependent intestinal diseases.

Abstract
AIM To evaluate the effect of early enteral nutrition on intestinal mucosal barrier and nutrition status in advanced esophageal cancer patients undergoing synchronous chemoradiotherapy.
METHODS Ninety-two advanced esophageal cancer patients undergoing synchronous chemoradiotherapy from July 2015 to October 2016 were divided into an intervention group and a control group. The control group was given routine diet or intravenous nutrition support, and the intervention group was given early enteral nutrition support. One month after treatment, intestinal mucosal barrier, serum nutrition indexes, and short-term efficacy were compared between the two groups.
RESULTS Serum endotoxin, diamine oxidase, and D-lactic acid were significantly lower in the intervention group than in the control group (10.24 ± 2.12 EU/L vs 15.45 ± 3.21 EU/L, 5.65 ± 0.82 U/L vs 8.05 ± 1.35 U/L, 0.29 ± 0.07 μmol/L vs 0.35 ± 0.08 μmol/L; t = 9.186, 10.306, 3.828; P < 0.05 or 0.01). Serum albumin, prealbumin, and transferrin were significantly higher in the intervention group than in the control group (32.41 ± 4.35 g/L vs 28.45 ± 4.32 g/L, 0.26 ± 0.0 g/L vs 0.19 ± 0.06 g/L, 1.82 ± 0.36 vs 1.45 ± 0.32; t = 4.381, 4.748, 5.210; P < 0.05). Remission rate and control rate were significantly higher in the intervention group than in the control group (80.43% vs 60.87%, 91.30% vs 76.09%; χ2 = 4.246, 3.903; P < 0.05).
CONCLUSION Early enteral nutrition support can help improve the short-term efficacy in advanced esophageal cancer patients undergoing synchronous chemoradiotherapy, which may be related to protecting intestinal mucosal barrier function and improving the nutritional status.

Abstract
The goal of this study was to clarify the protective role of the Wnt/β-catenin pathway agonist SKL2001 in a rat model of Caerulein-induced acute pancreatitis. AR42J cells and rats were divided into 4 groups: control, Caerulein, SKL2001 + Caerulein, and SKL2001 + control. Cell apoptosis was examined using flow cytometry. Hematoxylin-eosin staining was performed to observe pathological changes in pancreatic and small intestinal tissues. Inflammatory cytokines were detected by enzyme-linked immunosorbent assay (ELISA), while genes related to the Wnt/β-catenin pathway were quantified using quantitative real-time PCR. In vitro results showed that Caerulein promoted cell necrosis, inhibited the Wnt/β-catenin pathway, and increased the level of inflammatory cytokines. However, SKL2001 reduced cell necrosis and inflammatory cytokines and activated the Wnt/β-catenin pathway. Additionally, in vivo results demonstrated the accumulation of fluid (i.e., edema), hemorrhage, inflammation and necrosis of the pancreatic acini occurred 6 h after the final Caerulein induction, with the damage reaching a maximal level 12 h after the final Caerulein induction; meanwhile, the Wnt/β-catenin pathway was evidently inhibited with an enhanced level of inflammatory cytokines. The aforementioned damage was further aggravated 12 h later. Nevertheless, the pancreatic and small intestinal tissue damages were alleviated in Caerulein-induced rats treated with SKL2001. In conclusion, activation of the Wnt/β-catenin pathway could inhibit Caerulein-induced cell apoptosis and inflammatory cytokine release, thus improving pancreatic and intestinal damage in rats with acute pancreatitis.

Abstract
The present study aimed to investigate the expression and function of aquaporin (AQP)9 in the intestinal tract of acute liver injury rat models. A total of 20 Sprague Dawley rats were randomly divided into four groups: Normal control (NC) group and acute liver injury groups (24, 48 and 72 h). Acute liver injury rat models were established using D-amino galactose, and the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (Tbil) and albumin were determined using an automatic biochemical analyzer. Proteins levels of myosin light chain kinase (MLCK) in rat intestinal mucosa were investigated via immunohistochemistry. Pathological features were observed using hematoxylin and eosin (H&E) staining. MLCK, AQP9 and claudin-1 protein expression levels were detected via western blotting. Levels of ALT and AST in acute liver injury rats were revealed to steadily increase between 24 and 48 h time intervals, reaching a peak level at 48 h. Furthermore, TBil levels increased significantly until 72 h. Levels of ALT were revealed to significantly increase until the 48 h time interval, and then steadily decreased until the 72 h time interval. The acute liver injury 72 h group exhibited the greatest levels of MLCK expression among the three acute liver injury groups; however, all three acute liver injury groups exhibited enhanced levels of MLCK expression compared with the NC group. Protein levels of AQP9 and claudin-1 were enhanced in the NC group compared with the three acute liver injury groups. H&E staining demonstrated that terminal ileum mucosal layer tissues obtained from the acute liver injury rats exhibited visible neutrophil infiltration. Furthermore, the results revealed that levels of tumor necrosis factor-α, interleukin (IL)-6 and IL-10 serum cytokines were significantly increased in the acute liver injury groups. In addition, AQP9 protein expression was suppressed in acute liver injury rats, which induced pathological alterations in terminal ileum tissues may be associated with changes of claudin-1 and MLCK protein levels.

Abstract
BACKGROUND Whether to conduct enteral nutrition in patients with severe acute pancreatitis (SAP) during the active phase of intestinal stress or to feed during remission remains controversial. This study was aimed to evaluate the efficacy and safety of enteral nutrition within 48 hours after admission in the patients with SAP or predicted severe acute pancreatitis (pSAP). METHODS We searched PubMed, EMBASE, Web of Science, and the Cochrane Library before December 2017. Randomized controlled trials of early enteral nutrition (starting within 48 hours after admission) versus late enteral nutrition or total parental nutrition in severe acute pancreatitis or predicted severe acute pancreatitis were selected. RESULTS Ten randomized controlled trials containing 1051 patients were included. Comparing early enteral nutrition to late enteral nutrition or total parental nutrition in SAP or pSAP, the pooled risk ratios were 0.53 (95% confidence interval [CI] 0.35-0.81, P = .003) for mortality, 0.58 (95% CI 0.43-0.77, P = .0002) for multiple organ failure (MOF), 0.50 (95% CI 0.33-0.75, P = .0008) for operative intervention, 0.75 (95% CI 0.61-0.93, P = .009) for systemic infection, 0.42 (95% CI 0.26-0.69, P = .0005) for local septic complications, 0.84 (95% CI 0.74-0.96, P = .01) for gastrointestinal symptoms. 0.87 (95% CI 0.74-1.02, P = .08) for systemic inflammatory response syndrome (SIRS), and 1.24 (95% CI 0.66-2.31, P = .50) for other local complications. CONCLUSIONS Enteral nutrition within 48 hours after admission is efficient and safe for the patients with SAP or pSAP.

Abstract
AIM To evaluate the effect of octreotide combined with omeprazole on gastrointestinal hormones and intestinal mucosal barrier function in patients with acute pancreatitis (AP).
METHODS One hundred and twenty-four patients with AP treated from July 2016 to June 2017 at People's Hospital of Guyuan were divided into an observation group and a control group. The control group was given omeprazole alone, and the observation group was given octreotide combined with omeprazole. Two weeks after treatment, the clinical efficacy, clinical symptoms, gastrointestinal hormones, intestinal mucosal barrier function, and adverse reactions were compared between the two groups.
RESULTS The effective rate was significantly higher in the observation group than in the control group [90.32% (59/62) vs 80.65% (50/62), χ2 = 6.143, P < 0.05). Time to disappearance of fever, abdominal pain, nausea and vomiting, abdominal distension, abdominal tenderness, and other clinical symptoms and signs was significantly shorter in the observation group than in the control group (2.12 d ± 0.55 d vs 4.56 d ± 0.72 d, 1.75 d ± 0.42 d vs 4.34 d ± 0.70 d, 2.23 d ± 0.56 d vs 4.65 d ± 0.74 d, 2.54 d ± 0.60 d vs 4.12 d ± 0.76 d, 2.12 d ± 0.53 d vs 4.24 d ± 0.75 d; t = 21.205, 24.982, 20.533, 20.185, 18.177, P < 0.01). Serum MTL was significantly higher and serum GAS and VIP were significantly lower in the observation group than in the control group (318.36 pg/mL ± 30.24 pg/mL vs 256.45 pg/mL ± 34.23 pg/mL, 14.12 μmol/L ± 16.25 μmol/L vs 130.24 μmol/L ± 16.45 μmol/L, 58.12 pg/mL ± 7.25 pg/mL vs 64.36 pg/mL ± 8.12 pg/mL; t = 10.673, 5.489, 4.514, P < 0.05 or P < 0.01). Serum ET, DLA, DAO, and AMY were significantly lower in the observation group than in the control group (53.12 ng/L ± 7.25 ng/L vs 64.20 ng/L ± 7.36 ng/L, 4.45 μg/L ± 0.78 μg/L vs 6.42 μg/L ± 0.86 μg/L, 6.47 U/L ± 1.12 U/L vs 9.10 U/L ± 1.26 U/L, 124.36 U/L ± 24.35 U/L vs 160.21 U/L ± 26.54 U/L; t = 8.445, 13.360, 12.284, 7.818, P < 0.05 or P < 0.01). The rate of adverse reactions was significantly lower in the observation group than in the control group [8.06% (5/62) vs 24.19% (15/62), χ2 = 5.962, P < 0.05].
CONCLUSION Octreotide combined with omeprazole can improve clinical symptoms and clinical curative effect and reduce adverse reactions in patients with AP, which may be related to regulating gastrointestinal hormones and improving intestinal mucosal barrier function.

Abstract
The combination of molecular pathogen diagnostics and the biomarker procalcitonin (PCT) are changing the use of antimicrobials in patients admitted to critical care units with severe community-acquired pneumonia, possible septic shock, or other clinical syndromes. An elevated serum PCT level is good supportive evidence of a bacterial pneumonia, whereas a low serum PCT level virtually eliminates an etiologic role for bacteria even if the culture for a potential bacterial pathogen is positive. Serum PCT levels can be increased in any shocklike state; a low PCT level eliminates invasive bacterial infection as an etiology in more than 90% of patients.

Abstract
Intestinal mucosal immune barrier dysfunction plays a key role in the pathogenesis of severe acute pancreatitis (SAP). Rhubarb is a commonly used traditional Chinese medicine as a laxative in China. It markedly protects pancreatic acinar cells from trypsin-induced injury in rats. Free total rhubarb anthraquinones (FTRAs) isolated and extracted from rhubarb display the beneficial effects of antibacteria, anti-inflammation, antivirus, and anticancer. The principal aim of the present study was to investigate the effects of FTRAs on the protection of intestinal injury and modification of the intestinal barrier function through regulation of intestinal immune function in rats with SAP. We established a rat model of SAP by injecting 3.5% sodium taurocholate (STC, 350 mg/kg) into the biliopancreatic duct via retrograde injection and treated the rats with FTRAs (36 or 72 mg/kg) or normal saline (control) immediately and 12 h after STC injection. Then, we evaluated the protective effect of FTRAs on intestinal injury by pathological analysis and determined the levels of endotoxin (ET), interleukin 1β (IL-1β), tumor necrosis factor α (TNF-α), nitric oxide (NO), myeloperoxidase (MPO), capillary permeability, nucleotide-binding oligomerization domain-like receptors 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD domain (ASC), casepase-1, secretary immunoglobulin A (SIgA), regulatory T cells (Tregs), and the ratio of Th1/Th2 in the blood and/or small intestinal tissues or mesenteric lymph node (MLN) cells. Moreover, the chemical profile of FTRAs was analyzed by HPLC-UV chromatogram. The results showed that FTRAs significantly protected intestinal damage and decreased the levels of ET, IL-1β, TNF-α, and NO in the blood and TNF-α, IL-1β, and protein extravasation in the intestinal tissues in SAP rats. Furthermore, FTRAs significantly decreased the expressions of NLRP3, ASC, and caspase-1, the number of Tregs and the ratio of Th1/Th2, while significantly increased the expression of SIgA in the intestinal tissues and/or MLN cells in SAP rats. Our results indicate that FTRAs could protect intestinal injury and improve intestinal mucosal barrier function through regulating immune function of SAP rats. Therefore, FTRAs may have the potential to be developed as the novel agent for the treatment of SAP clinically.
