PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 129:155708. [PMID: 38733906 DOI: 10.1016/j.phymed.2024.155708] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 04/22/2024] [Accepted: 05/02/2024] [Indexed: 05/13/2024]
Abstract
BACKGROUND Pancreatitis is a common exocrine inflammatory disease of the pancreas and lacks specific medication currently. Rhei Radix et Rhizoma (RR) and its anthraquinone derivatives (AQs) have been successively reported for their pharmacological effects and molecular mechanisms in experimental and clinical pancreatitis. However, an overview of the anti-pancreatitis potential of RR and its AQs is limited. PURPOSE To summarize and analyze the pharmacological effects of RR and its AQs on pancreatitis and the underlying mechanisms, and discuss their drug-like properties and future perspectives. METHODS The articles related to RR and its AQs were collected from the Chinese National Knowledge Infrastructure, Wanfang data, PubMed, and the Web of Science using relevant keywords from the study's inception until April first, 2024. Studies involving RR or its AQs in cell or animal pancreatitis models as well as structure-activity relationship, pharmacokinetics, toxicology, and clinical trials were included. RESULTS Most experimental studies are based on severe acute pancreatitis rat models and a few on chronic pancreatitis. Several bioactive anthraquinone derivatives of Rhei Radix et Rhizoma (RRAQs) exert local protective effects on the pancreas by maintaining pancreatic acinar cell homeostasis, inhibiting inflammatory signaling, and anti-fibrosis, and they improve systemic organ function by alleviating intestinal and lung injury. Pharmacokinetic and toxicity studies have revealed the low bioavailability and wide distribution of RRAQs, as well as hepatotoxicity and nephrotoxicity. However, there is insufficient research on the clinical application of RRAQs in pancreatitis. Furthermore, we propose effective strategies for subsequent improvement in terms of balancing effectiveness and safety. CONCLUSION RRAQs can be developed as either candidate drugs or novel lead structures for pancreatitis treatment. The comprehensive review of RR and its AQs provides references for optimizing drugs, developing therapies, and conducting future studies on pancreatitis.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 308:116266. [PMID: 36806482 DOI: 10.1016/j.jep.2023.116266] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 02/09/2023] [Accepted: 02/10/2023] [Indexed: 06/18/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rhubarb is the peeled and dried root of Rheum palmatum L., Rheum tanguticum Maxim. ex Balf. or Rheum officinale Baill. Free total rhubarb anthraquinones (FTRAs) isolated and extracted from rhubarb display the beneficial effects of anti-inflammation and immunological modulation. The timing of immune regulation is a major problem in the immunotherapy for severe acute pancreatitis (SAP). several studies reported that FTRAs could reduce systemic inflammatory responses by inhibiting early immune overactivity in the gut in rats with SAP. But, the optimal timing of rhubarb and FTRAs administration is not clear in clinical practice. Therefore, the time window for the best efficacy of rhubarb and FTRAs in the treatment of SAP patients should be further elucidated. AIM OF THE STUDY The main purpose of the present study was to evaluate the efficacy and optimal timing of immune modulation with FTRAs in the treatment of SAP in rats. MATERIALS AND METHODS FTRAs (22.5, 45 and 90 mg/kg), Rhubarb (RHU) (900 mg/kg, positive control) or normal saline (vehicle control) were initiated at 0 (immediately), 48 and 72 h every 12 h for three times in total. The therapeutic effects of FTRAs and RHU on pancreas and intestinal tissues injury, secondary infection with pseudomonas aeruginosa (PA), amylase, lipase, D-lactic acid (DLA), endotoxin (ET), proinflammatory and anti-inflammatory cytokines, macrophages, dendritic cells and regulatory T cells (Tregs) in the blood, small intestine and/or mesenteric lymph node (MLN) were determined in rats with SAP after treatment. RESULTS The results showed that administration of FTRAs at 0 h was superior to 48 h and 72 h, which significantly protected the injury of pancreas and intestinal tissues, reduced the mortality induced by secondary infection with PA, decreased the levels of amylase, lipase, DLA, ET, tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), IL-6, IL-8, IL-18 and Tregs, and increased the levels of IL-4, sTNF-αR, macrophages and dendritic cells, secretary immunoglobulin A (SIgA) in the blood and/or small intestinal tissues in rats with SAP. CONCLUSIONS In conclusion, our studies indicate that the treatment window of FTRAs for SAP is within 48 h of development, administration of FTRAs at the early stage (0 h, immune overreaction period) was the optimal time and superior to that of 48 h and 72 h for its therapeutic efficacy. The earlier the administration of FTRAs, the better the therapeutic efficacy. Therefore, our data may provide a scientific rationale for the clinical application and optimal timing of FTRAs in the treatment of SAP.

Abstract
Rhubarb (also named Rhei or Dahuang), one of the most ancient and important herbs in traditional Chinese medicine (TCM), belongs to the Rheum L. genus from the Polygonaceae family, and its application can be traced back to 270 BC in "Shen Nong Ben Cao Jing". Rhubarb has long been used as an antibacterial, anti-inflammatory, anti-fibrotic and anticancer medicine in China. However, for a variety of reasons, such as origin, variety and processing methods, there are differences in the effective components of rhubarb, which eventually lead to decreased quality and poor efficacy. Additionally, although some papers have reviewed the relationship between the active ingredients of rhubarb and pharmacologic actions, most studies have concentrated on one or several aspects, although there has been great progress in rhubarb research in recent years. Therefore, this review aims to summarize recent studies on the geographic distribution, taxonomic identification, pharmacology, clinical applications and safety issues related to rhubarb and provide insights into the further development and application of rhubarb in the future.

Abstract
Background: Gastrointestinal dysfunction plays a critical role in the prognosis of critically ill patients. Previous studies showed rhubarb, a traditional Chinese herb, can protect the intestinal barrier function, prevent intestinal bacterial translocation, and promote gastrointestinal peristalsis, but the clinical studies are less. The aim of this study was to evaluate the effects of rhubarb on gastrointestinal dysfunction in critically ill patients. Methods: From June 2015 to May 2017, a total of 368 critically ill patients with Grade I–III acute gastrointestinal injury (AGI) were enrolled in this study. Patients were divided into two groups according to the exposure factors (whether the patients received rhubarb treatment): the rhubarb group and the usual treatment group. Clinical data were collected within the first 24 h of the Intensive Care Unit (ICU) admission and 7 days after treatment. Survival data on day 28 after ICU admission and the durations of ICU and total hospitalization were also collected. Propensity score matching (PSM) was conducted to reduce confounding bias between the groups. The logistic regression was conducted to screen the influence factors. Results: The eligible patients were divided into rhubarb group (n = 219, 59.5%) and usual treatment group (n = 149, 40.5%). Before PSM, the remission rate of feeding intolerance in rhubarb group and usual treatment group were 59.8% and 39.6%, respectively. After PSM, the remission rate of feeding intolerance in rhubarb group and usual treatment group was 77.9% and 30.9%, respectively. The remission rates of feeding intolerance in rhubarb group were significantly higher than those in the usual treatment group (all P < 0.05). Compared with the usual treatment group, the rhubarb group had a higher rate of AGI improvement, lower level of C-reactive protein, shorter stay in ICU before and after PSM (P < 0.05). There was no significant difference in 28-day mortality between rhubarb and usual treatment groups before and after PSM (48 vs. 33, P = 0.959; and 16 vs. 21, P = 0.335). The logistic regression analysis showed that the single factor, whether receiving rhubarb therapy, affected the proportion of patients whose enteral nutrition needs ≥83.7 kJ·kg−1·d−1 after 7 days of treatment (odds ratio: 7.908, 95% confidence interval: 3.661–17.083, P < 0.001). No serious adverse effects were found in two groups. Conclusions: The rhubarb might significantly improve feeding tolerance and relieve gastrointestinal dysfunction in critically ill patients, without serious adverse reactions. It provided proof for the treatment of gastrointestinal dysfunction with rhubarb during clinical practice.

Abstract
Caspase recruitment domain-containing protein 9 (Card9) is located upstream of the nuclear factor kappa B (NF-κB) and p38 mitogen-activated protein kinase (MAPK) inflammatory pathways. This study investigated the therapeutic effect and potential mechanism of pioglitazone in rats with severe acute pancreatitis (SAP). SAP was induced by a retrograde infusion of 5.0% sodium taurocholate into the biliopancreatic duct of Sprague Dawley rats (n=54), which were then treated with pioglitazone. Blood and pancreatic tissues were harvested at 3, 6, and 12 h after SAP induction. Pancreatic pathological damage was evaluated by hematoxylin and eosin staining. Serum amylase, serum pro-inflammatory cytokines, and pancreatic myeloperoxidase (MPO) activities were determined by enzyme-linked immunosorbent assay. The expression of Card9 mRNA and protein in pancreatic tissues was detected by real-time polymerase chain reaction and western blotting. Pioglitazone had a therapeutic effect in treating rats with SAP by decreasing the level of amylase activity, ameliorating pancreatic histological damage, decreasing serum pro-inflammatory cytokine levels and tissue MPO activity, and downregulating the expression of NF-κB, p38MAPK, and Card9 mRNAs and proteins (P<0.05). The present study demonstrated that the inhibition of Card9 expression could reduce the severity of SAP. Card9 has a role in the pathogenic mechanism of SAP.

Abstract
BACKGROUND Dai-Huang-Fu-Zi-Tang (DHFZT) is a famous traditional Chinese prescription with intestinal obstruction, acute pancreatitis and cholecystalgia for thousands of years. Our previous work found that DHFZT could act against pulmonary and intestinal pathological injury in rats with severe acute pancreatitis (SAP). But the underlying mechanism has not been fully elucidated. The aim of present study was to investigate whether DHFZT could relieve pulmonary and intestinal injury by regulating aquaporins after SAP induced by sodium taurocholate in rats. METHODS Forty of SD rats were used for dose dependant experiments of DHFZT.Accurate-mass Time-of-flight liquid chromatography-mass spectrometry was used for qualitative screening of chemical compositions of DHFZT. Twenty-four rats were randomly divided into 3 groups: sham group (n = 8), model group (SAP, n = 8), DHFZT group (SAP with DHFZT treatment, n = 8). SAP models were established by retrograde injections of 5% sodium taurocholate solutions into rat pancreaticobiliary ducts. Blood samples were taken at 0, 12, 24, 48 h post-operation for detecting serum amylase, lipase, endotoxin, TNF-α, IL-6 and IL-10. Protein expression and location of aquaporin (AQP)1, 5, 8 and 9 were assessed by immunohistochemistry, western blot and immunofluorescence respectively. RESULTS The study showed that 27 kinds of chemical composition were identified, including 10 kinds in positive ion mode and 17 kinds in negative ion mode. The results showed that AQP1, AQP5 of lung, and AQP1, AQP5, AQP8 of intestine in model group were significantly lower than that of sham group (P < 0.05), and which were obviously reversed by treatment with DHFZT. In addition, protein levels of pro-inflammatory cytokines such as TNF-α, IL-6 and endotoxin in peripheral blood were significantly suppressed by DHFZT, and that anti-inflammatory cytokine like IL-10 was just opposite. Finally, we also noted that DHFZT reduced serum levels of amylase, lipase and endotoxin, and also improved edema and pathological scores of lung and intestine after SAP. CONCLUSIONS DHFZT ameliorated the pulmonary and intestinal edema and injury induced by SAP via the upregulation of different AQPs in lung and intestine, and suppressed TNF-α, IL-6 expression and enhanced IL-10 expression.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rhubarb is one of the common herbs used in traditional Chinese complex prescriptions for the treatment of various inflammatory diseases. We sought to determine the add-on effect of crude rhubarb to somatostatin in patients with acute pancreatitis by conducting a meta-analysis. MATERIALS AND METHODS We searched the Pubmed, EMBASE, Cochrane Library, CNKI, Wanfang, VIP databases up to November 2015. Randomized controlled trials (RCTs) comparing crude rhubarb plus somatostatin to somatostatin alone for acute pancreatitis were included. Risk ratio (RR) or weighted mean difference (WMD) with their 95% confidence interval (CI) was calculated between with and without crude rhubarb therapy. RESULTS A total of 19 RCTs involving 1161 patients were identified. Compared with somatostatin alone, crude rhubarb plus somatostatin significantly reduced the total complications (RR 0.55; 95% CI 0.41-0.73) and APACHE Ⅱ scores (WMD -1.16; 95% CI -1.91 to -0.41) as well as shortened the duration of elevated serum amylase (WMD -2.01 days; 95% CI -2.57 to -1.44), duration of abdominal pain (WMD -1.33 days; 95% CI -1.61 to -1.05), the first defecation time (WMD -2.27 days; 95% CI -3.06 to -1.47), and duration of hospital stay (WMD -6.70 days; 95% CI -8.81 to -4.60). However, there were no significant differences in total mortality rates (RR 0.61; 95% CI 0.34 to 1.12) between two groups. CONCLUSIONS Crude rhubarb as adjuvant therapy to somatostatin appears to have additional benefits in patients with acute pancreatitis. However, interpretation of these results should be cautioned due to the methodological flaws.

Abstract
Emodin is an anthraquinone derived from Chinese herb that exerts anti-inflammation effects. This study aimed to investigate whether emodin provides the protection for jejunum injury by inhibiting inflammation. We established a model of sepsis caused by cecal ligation and puncture. Forty-eight male Wistar rats were divided into four groups (n=12). Jejunum injury was assessed by pathological examination. The activity of pJAK1/pSTAT3 and protein levels of Bcl-2 and Bax were detected by Western blot analysis. Inflammatory factors IL-6, TNF-α and procalcitonin were detected by ELISA. Apoptosis was detected by TUNEL. We found that emodin alleviated jejunum damage and apoptosis induced by sepsis and decreased the levels of IL-6, TNF-α and procalcitonin in septic rats. Furthermore, we observed that emodin increased the levels of pJAK1 and of pSTAT3, which were decreased in rats with sepsis. In addition, emodin enhanced the expression of Bcl-2 which was downregulated by sepsis and decreased the expression of Bax which was upregulated by sepsis. In conclusion, these results indicate that emodin suppresses inflammatory response induced by sepsis. Emodin activates JAK1/STAT3 signaling pathway and regulates Bcl-2 and Bax expression to protect the jejunum in rats with sepsis.

Abstract
AIM: To observe the clinical effects of administration of rhubarb by both nasal feeding and enema in the treatment of acute pancreatitis (AP).
METHODS: Eighty-three AP patients were randomly divided into three groups: A, B and C. Group A was given conventional treatment, group B was additionally administered with rhubarb by both nasal feeding and enema on the basis of conventional therapy, and group C was additionally administered with rhubarb by nasal feeding on the basis of conventional therapy. Hospitalization costs, hospitalization time, time to recovery of intestinal function, Ranson score, CT classification, plasma calcitonin (PCT) and C reactive protein (CRP) were compared for the three groups.
RESULTS: In all the three groups, no patients died. Time to intestinal function recovery, average length of hospital stay and hospitalization costs were significantly lower in group B than in the other two groups (P < 0.05 for all). After one week of treatment, CT grade, CRP and PCT were significantly decreased (P < 0.05).
CONCLUSION: Double routes of administration of rhubarb in AP patients can promote the recovery of intestinal function, reduce the inflammatory response, shorten the length of hospital stay, reduce medical costs, and improve prognosis.

Abstract
BACKGROUND Prokinetic agents are sometimes needed to aid in the placement of nasojejunal feeding tubes in patients at risk of malnutrition. The objective of the present study was to evaluate the feasibility of rhubarb as a new prokinetic agent to replace metoclopramide and erythromycin in the placement of nasojejunal feeding tubes. MATERIALS AND METHODS Ninety-four patients who required jejunal feeding tube insertion were included. They were divided into rhubarb (n = 34), metoclopramide (n = 31), and erythromycin groups (n = 29), depending on the use of rhubarb, metoclopramide, and erythromycin as the prokinetic agent. The jejunal feeding tube insertions were performed at the bedside. An abdominal x-ray was taken as the gold standard to determine the position of the tube. Cases in which insertion failed in either group were subjected to a second insertion attempt using rhubarb as the prokinetic agent. RESULTS The success rates in the rhubarb, metoclopramide, and erythromycin groups were 91.2%, 87.1%, and 89.7%, respectively. The difference in the success rates was not statistically significant (P = .916). The insertion times in the rhubarb, metoclopramide, and erythromycin groups were 16.0 ± 1.9 minutes, 18.0 ± 1.9 minutes, and 18.8 ± 2.2 minutes, respectively. The insertion time in the rhubarb group was significantly shorter than those in metoclopramide and erythromycin groups (P < .001). No side effects were noted in the rhubarb group. CONCLUSIONS Rhubarb could serve as an effective prokinetic agent to promote the insertion of nasojejunal feeding tubes.

Abstract
OBJECTIVE The aim of this study was to examine the effects of rhubarb on intestinal flora and toll-like receptors (TLRs) of intestinal mucosa in rats with severe acute pancreatitis (SAP). METHODS Healthy male Sprague-Dawley rats were randomly allocated into sham-operated surgical model of SAP without or with postoperative rhubarb treatment groups (7 in each group). Rats in with rhubarb group received 10% rhubarb decoction (1 mL/200 g) through tube feeding at every 8 hours during postoperative 24 hours. Serum amylase, amount of intestinal flora, and TLR2/TLR4 messenger RNA expression in intestinal mucosa were tested among 3 groups at postoperative 24 hours. RESULTS TLR2 and TLR4 messenger RNA expression levels in intestinal mucosa in SAP without rhubarb group were significantly higher than those in sham-operated or SAP with rhubarb groups (P < 0.05). The amount of intestinal lactobacilli and bifidobacteria in SAP without rhubarb group were significantly fewer than in those sham-operated group (P < 0.05) but not significantly different from those in SAP with rhubarb group (P > 0.05). The amount of intestinal Escherichia coli was relatively higher in SAP group than in sham-operated group (P > 0.05) but lesser in rhubarb treatment group (P > 0.05). CONCLUSIONS Rhubarb might maintain the intestinal mucosal barrier through regulating intestinal flora and inhibiting intestinal inflammatory response in rats with SAP.

World J Gastroenterol 2014; 20:16570-16581. [PMID: 25469025 PMCID: PMC4248200 DOI: 10.3748/wjg.v20.i44.16570] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2014] [Revised: 03/10/2014] [Accepted: 05/14/2014] [Indexed: 02/06/2023] Open
Abstract
Despite enthusiastic efforts directed at elucidating critical underlying mechanisms towards the identification of novel therapeutic targets for severe acute pancreatitis (SAP), the disease remains without a specific therapy to be executed within the first hours to days after onset of symptoms. Although earlier management for SAP should aim to either treat organ failure or reduce infectious complications, the current standard of care for the general management of AP in the first hours to days after onset of symptoms include intravenous fluid replacement, nutritional changes, and the use of analgesics with a close monitoring of vital signs. Furthermore, repeated evaluation of severity is very important, as the condition is particularly unstable in the early stages. In cases where biliary pancreatitis is accompanied by acute cholangitis or in cases where biliary stasis is suspected, an early endoscopic retrograde cholangiopancreatography is recommended. However, practice guidelines regarding the treatment of pancreatitis are suboptimal. In chronic pancreatitis, conservative management strategies include lifestyle modifications and dietary changes followed by analgesics and pancreatic enzyme supplementation. Recently, attention has been focused on phytoceuticals or antioxidants as agents that could surpass the limitations associated with currently available therapies. Because oxidative stress has been shown to play an important role in the pathogenesis of pancreatitis, antioxidants alone or combined with conventional therapy may improve oxidative-stress-induced organ damage. Interest in phytoceuticals stems from their potential use as simple, accurate tools for pancreatitis prognostication that could replace older and more tedious methods. Therefore, the use of antioxidative nutrition or phytoceuticals may represent a new direction for clinical research in pancreatitis. In this review article, recent advances in the understanding of the pathogenesis of pancreatitis are discussed and the paradigm shift underway to develop phytoceuticals and antioxidants to treat it is introduced. Despite the promise of studies evaluating the effects of antioxidants/phytoceuticals in pancreatitis, translation to the clinic has thus far been disappointing. However, it is expected that continued research will provide solid evidence to justify the use of antioxidative phytoceuticals in the treatment of pancreatitis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Da-Huang-Fu-Zi-Tang (DHFZT) is a famous traditional Chinese prescription with strong anti-inflammatory effects. Our previous work found that DHFZT could act against pancreatic injury in rats with severe acute pancreatitis (SAP) via inhibiting the Janus kinase 2/signal transducers and activators of transcription 3 (JAK2/STAT3) signaling pathway in pancreatic tissues. AIM OF THE STUDY To investigate the therapeutic effects of DHFZT on liver injury in SAP rats, and the effects on JAK2/STAT3 signaling in liver tissue and Kupffer cells (KCs). MATERIALS AND METHODS Fifty SD male rats were randomly divided into five groups: sham operation group (SO), SAP model group, DHFZT treatment groups (12, 24, and 48 mg/kg body weight). The model of SAP was constructed by injecting sodium taurocholate (3.5%) into pancreatic and biliary ducts. One hour before constructing the model, DHFZT was perfused into the stomach. All rats were sacrificed after 24h following the operation; livers were examined with hematoxylin and eosin staining. The protein expression of pJAK2 and pSTAT3 in liver tissue was detected by immunohistochemical staining. The activity of ALT, IL-6 and TNF-α in serum was detected. KCs of each group were isolated. After culture for 4h, the protein expression of JAK2, pJAK2, STAT3 and pSTAT3, the mRNA expression of IL-6 and TNF-α in KCs were examined. RESULTS Sodium taurocholate induced liver injury concomitant with increased expression of pJAK2 and pSTAT3 in liver tissue and KCs. Pretreatment with DHFZT significantly attenuated liver injury induced by SAP, and concurrently, effectively lowered the serum ALT level. Furthermore, our studies showed that DHFZT obviously decreased the expression of pJAK2 and pSTAT3 in liver tissue and KCs. CONCLUSIONS DHFZT could ameliorate liver injury in rats with SAP.

Regulatory roles of the PI3K/Akt signaling pathway in rats with severe acute pancreatitis. PLoS One 2013; 8:e81767.

Abstract
The phosphatidylinositol 3-kinase(PI3K)/protein kinase B (Akt) pathway plays a key role in inflammation. However, the regulatory roles of PI3K/Akt in severe acute pancreatitis (SAP) have not been elucidated. The aim of this study was to investigate the impact of wortmannin, a PI3K/Akt inhibitor, on SAP rats through exposure to sodium taurocholate (STC) after 3 h and 6 h. The SAP group was found to have a significant increase in pancreas Akt expression, along with the activation of serum amylase, TNF-α, IL-1β, and IL-6, and pancreas histological aggravation. The administration of wortmannin in SAP rats reduced Akt expression, attenuated the level of serum amylase and inflammation factor, and alleviated the damage of pancreatic tissue. Furthermore, the administration of wortmannin led to an obvious reduction in NF-κB and p38MAPK expression in SAP rats. These findings showed that the PI3K/Akt inhibitor wortmannin decreases inflammatory cytokines in SAP rats and suggests its regulatory mechanisms may occur through the suppression on NF-κB and p38MAPK activity.

Liposomal clodronate reduces Akt and mitogen-activated protein kinase expression in the intestinal mucosa of rats with severe acute pancreatitis. Shijie Huaren Xiaohua Zazhi 2013; 21:2633-2640.

Abstract
AIM: To study the effect of liposomal clodronate on the expression of protein kinase B (Akt) and mitogen-activated protein kinase [MAPK (ERK1/2)] in the intestinal mucosa of rats with severe acute pancreatitis (SAP), and to investigate the mechanism behind the therapeutic effect of liposomal clodronate on SAP-associated intestinal mucosal injury.
METHODS: Liposomal clodronate was prepared by means of thin film. Forty-eight SD rats were randomly divided into a model control group (C), a liposome control group (P), and a liposomal clodronate group (T). SAP was induced in rats of groups P and T by injection of sodium taurocholate under the pancreatic capsule, while group C received equal volume of normal saline. Serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and AMS were measured 2 and 6 h after SAP induction. Pathological alterations in the intestinal mucosa were observed.
RESULTS: Serum levels of AMS, IL-6 and TNF-α were significantly elevated in group P compared to group C (all P < 0.01). Compared with group P, serum levels of AMS, IL-6 and TNF-α were significantly decreased in group T (all P < 0.01). Pathological alterations (scores) in the intestinal mucosa were significantly attenuated in group T compared to group P. The expression of Akt and MAPK (ERK1/2) was significantly decreased in group T compared to group P.
CONCLUSION: Macrophages play an important role in the pathogenesis of intestinal mucosal injury in SAP. Macrophages can be depleted via phagocytosis of liposome encapsulated clodronate. Liposomal clodronate alleviates intestinal mucosal injury in SAP rats possibly by decreasing the expression of Akt and MAPK (ERK1/2).
