The intestine function recovery decoction (IFRD) is a traditional Chinese medicine that has been used for the treatment of adhesive intestinal obstruction. In this study, the preventative effects and probable mechanism of the IFRD were investigated in a rat model. We randomly assigned rats to five groups: normal, model, control, low dose IFRD, and high dose IFRD. In the animal model, the caecum wall and parietal peritoneum were abraded to induce intra-abdominal adhesion formation. Seven days after surgery, adhesion scores were assessed using a visual scoring system, and histopathological samples were examined. The levels of serum interleukin-6 (IL-6) and transforming growth factor beta-1 (TGF-β1) were analysed by an enzyme-linked immunosorbent assay (ELISA). The results showed that a high dose of IFRD reduced the grade of intra-abdominal adhesion in rats. Furthermore, the grades of inflammation, fibrosis, and neovascularization in the high dose IFRD group were significantly lower than those in the control group. The results indicate that the IFRD can prevent intra-abdominal adhesion formation in a rat model. These data suggest that the IFRD may be an effective antiadhesion agent.

Background. Many attempts have been made to inhibit the formation of postoperative intraperitoneal adhesions, but the results have been discouraging. Therefore, the identification of effective preventative measures or treatments is of great importance. In this study, the substantial potential of naringin (NG) to reduce peritoneal adhesions was validated in a rat model. Materials and Methods. A rat peritoneal adhesion model was established by abrasion of the cecum and its opposite intraperitoneal region under aseptic surgical conditions. After the operation, three groups of NG-treated rats were given 2 mL of NG by gavage at different concentrations (40, 60, or 80 mg/kg/d). The sham, control, and hyaluronan (HA) groups were given equal volumes of normal saline daily. On the 8th day, all rats were sacrificed 30 min after the administration of an activated carbon solution (10 mL/kg) by oral gavage. Intraperitoneal adhesion formation was adequately evaluated by necropsy, hematoxylin and eosin (HE) staining, Sirius red staining, immunofluorescence staining, enzyme-linked immunosorbent assays, and reactive oxygen species (ROS) probes. The gastrointestinal dynamics of the rats were assessed on the basis of a small intestinal charcoal powder propulsion test and the detection of motilin and gastrin levels in serum. Results. Intraperitoneal adhesions were markedly reduced in the group of rats receiving high-dose NG. Compared with the control group, the high-dose NG group showed clear reductions in inflammatory reactions, oxidative stress, collagen deposition, and fibroblast formation in the adhesion tissue and enhanced gastrointestinal dynamics ( P  < 0.05). Conclusion. NG alleviated the severity of intraperitoneal adhesions in a rat model by reducing inflammation, oxidative stress, collagen deposition, and fibroblast formation, highlighting the potential of NG as a drug candidate to prevent postoperative peritoneal adhesion formation.

The aim of this study was to observe the therapeutic effect of curcumin chitosan microspheres (CCM) on ulcerative colitis (UC) in rats. Rat UC model was prepared by 2,4,6-trinitrobenzenesulfonic acid (TNBS) method. All animals were divided into blank control group (BCG), model control group (MCG), mesalazine enteric-coated tablets group (MECT), curcumin chitosan microsphere low (CCML), medium (CCMM) and high dose groups (CCMH). Starting from the third day after model establishment, the rats were intra-gastrically administered for 10 days. On the 14th day of the experiment, the rats were sacrificed. The colon tissues and serum samples were collected and the expression of NF-κB P65 protein was detected by immune histochemical streptavidin-perosidase (SP) method. The levels of IL-1β, IL-4 and IL-6 in serum were determined by Enzyme Linked Immunosorbent Assay (ELISA). The colonic mucosal injury score of MCG was increased; The serum IL-1β and IL-6 levels were increased, while the IL-4 content was decreased; The expression of NF-κB in the colonic mucosa was reduced after TNBS challenge. The histological injury scores of colonic mucosa, the serum levels of IL-1β and IL-6 in CCM-treated rats were significantly decreased (P < 0.01) as compared with MECT group. While, the content of IL-4 was significantly higher than that of MCG and MECT groups (P < 0.01). Curcumin chitosan microspheres provide a potential therapeutic strategy for treating UC in clinic.

Background. Postoperative intra-abdominal adhesions are a major complication after abdominal surgery. Although various methods have been used to prevent and treat adhesions, the effects have not been satisfactory. Emodin, a naturally occurring anthraquinone derivative and an active ingredient in traditional Chinese herbs, exhibits a variety of pharmacological effects. In our study, we demonstrated the effect of emodin treatment on preventing postoperative adhesion formation. Materials and Methods. A total of 48 rats were divided into six groups. Abdominal adhesions were created by abrasion of the cecum and its opposite abdominal wall. In the experimental groups, the rats were administered daily oral doses of emodin. On the seventh day after operation, the rats were euthanized, and blood and pathological specimens were collected. Abdominal adhesion formation was evaluated by necropsy, pathology, immunohistochemistry, Western blot, and enzyme-linked immunosorbent assay analyses. Results. Abdominal adhesions were markedly reduced by emodin treatment. Compared with the control group, collagen deposition was reduced and the peritoneal mesothelial completeness rate was higher in the emodin-treated groups. Emodin had anti-inflammatory effects, reduced oxidative stress, and promoted the movement of the intestinal tract (P<0.05). Conclusion. Emodin significantly reduced intra-abdominal adhesion formation in a rat model.

Background: Intra-abdominal adhesions are a very common complication following abdominal surgery. Our previous studies have demonstrated that the inhibition of inflammation at the sites of peritoneal injury can prevent the formation of intra-abdominal adhesions. Resveratrol is a natural extract with a broad range of anti-inflammatory effects. Therefore, we propose that resveratrol can reduce the formation of intra-abdominal adhesions after surgery. The aim of this study was to investigate the effect of resveratrol on intra-abdominal adhesion prevention in a rat model with surgery-induced peritoneal adhesions. Materials and Methods: The cecum wall and its opposite parietal peritoneum were abraded following laparotomy to induce intra-abdominal adhesion formation. Varying doses of resveratrol were administered to the animals. On the eighth day after surgery, the adhesion score was assessed using a visual scoring system. Picrosirius red staining and a hydroxyproline assay were used to assess the amount of collagen deposition in the adhesion tissues. The levels of serum interleukin-6 (IL-6), tumor necrosis factor (TNF-α), and transforming growth factor beta-1 (TGF-β1) were determined by an enzyme-linked immunosorbent assay (ELISA). Western blotting was performed to determine the protein expression of TGF-β1, fibrinogen, and α-smooth muscle actin (α-SMA) in rat peritoneal adhesion tissue. Real-time RT-PCR was performed to quantify the mRNA expression of TGF-β1, fibrinogen, and α-SMA. Results: Resveratrol significantly reduced intra-abdominal adhesion formation and fibrin deposition in the rat model. Furthermore, resveratrol significantly reduced the serum levels of IL-6, TNF-α, and TGF-β1. The protein and mRNA expression of TGF-β1, fibrinogen, and α-SMA in the rat peritoneum and adhesion tissues were also down-regulated due to resveratrol intervention. Conclusion: Resveratrol can effectively prevent the formation of postoperative intra-abdominal adhesions in a rat model. This effect may be related to the suppression of inflammatory cytokine expression in the injured peritoneum by resveratrol. This study suggests that resveratrol may be a new and effective anti-adhesive agent that is worthy of further study and has potential application value.

In traditional Chinese medicine theory, blood stasis syndrome (BSS), characterized by blood flow retardation and blood stagnation, is one of the main pathologic mechanisms and clinical syndromes of cardiovascular diseases (CVDs). Rhodiola wallichiana var. cholaensis injection (RWCI) is made from dry roots and stems of RWC via the processes of decoction, alcohol precipitation, filtration, and dilution. Studies indicated the extracts of RWC could alleviate CVDs; however, the mechanism had not been illustrated. In the present study, the acute blood stasis rat model was established to investigate the pathogenesis of BSS and the therapeutic mechanism of RWCI against BSS. Hemorheological parameters (whole blood viscosity and plasma viscosity) and inflammatory factors (TNF-α and IL-6) were used to evaluate the success of the BSS rat model and RWCI efficacy. 14 and 33 differential metabolites were identified from plasma and urine samples using the metabolomics approach based on ultrahigh-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. The results of multivariate analysis displayed that there were significant separations among model, control, and treatment groups, but the high-dose RWCI treatment group was closer to the control group. 9 perturbed metabolic pathways were related to BSS’s development and RWCI intervention. 5 metabolic pathways (arachidonic acid metabolism, linoleic acid metabolism, alpha-linolenic acid metabolism, retinol metabolism, and steroid hormone biosynthesis) showed apparent correlations. These differential metabolites and perturbed metabolic pathways might provide a novel view to understand the pathogenesis of BSS and the pharmacological mechanism of RWCI.

The aim of this study was to investigate the effect of tenoxicam as a non-steroidal anti-inflammatory drug (NSAID) on intra-abdominal adhesion prevention in a rat model. Altogether 50 Wistar-Albino rats weighing 220 – 280 g were assigned to five groups, each of which was made up of 10 rats. All the rats were anaesthetized and prepared for sterile surgery. After a mid-line laparotomy was performed, a 1 cm area of the caecum was rubbed with gauze until subserosal haemorrhage developed, and then a 5 mm-diameter part of the peritoneum on the right side of the abdominal wall was removed. Prior to complete closure, 3 ml of the test material was placed into the abdominal cavity. On the eighth day the rats were killed and the adhesion score was determined. The groups and their mean adhesion scores were as follows: control group (normal saline), 2.5; group of dilution buffer, 1.8; tenoxicam (0.125 mg/kg), 1.3; tenoxicam (0.25 mg/kg), 1.3; and tenoxicam (0.5 mg/kg), 0.9. The differences between the adhesion scores among all the groups ( P < 0.05, Kruskal-Wallis test), and those between the tenoxicam groups and control group ( P < 0.05, Mann-Whitney U-test), were significant. Thus a single instillation of tenoxicam into the peritoneal cavity at the time of surgery reduced adhesion formation effectively in this model, irrespective of dosage.

<p>Background<br />Peritoneal adhesions (PAs) are generally described as fibrous bands between intra-abdominal organs following an abdominal surgical operation. The definitive treatments of PAs are currently ineffective yet. Hypoxia-mesenchymal stem cells (H-MSCs) have a higher capability to survive at the site of injury than normoxia-MSCs (N-MSCs) to repair injured tissue without fibrosis. This study aimed to analyze the effect of H-MSCs in controlling formation of PAs by reducing TGF-β level in a rat model. <br /><br />Methods <br />A study of post-test only control group design was conducted, involving eighteen PA rat models weighing 250 ± 25 g that were randomly assigned into 3 groups, comprising control group (C), and groups T1 and T2 receiving H-MSC treatment at doses of 3 x 106 and 1.5 x 106, respectively. To induce H-MSCs, MSCs were incubated in hypoxic conditions at 5% O2 and 37oC for 24 hours. Expression level of TGF-β was analyzed by enzyme-linked immunosorbent assay (ELISA) at 450 nm and adhesion formation was described macroscopically. The Kruskal-Wallis variance analysis was used to analyze significant differences among the groups.<br /><br />Results<br />The results of this study showed that H-MSCs in group T1 inhibited TGF-β expression significantly on day 8 (p&lt;0.001) and day 14 (p&lt;0.05). Moreover, there was almost no adhesion apparent following H-MSC administration in group T1. <br /><br />Conclusions<br />Based on this study, we conclude that H-MSCs may attenuate PA formation following inhibition of TGF-β expression in the PA rat model.</p>

Abstract Background Spleen-deficiency syndrome, an important pathological change in traditional Chinese medicine, has been proven to attribute to intestinal dysbacteriosis. Shengmai Yin (SMY), a classic formula for replenishing qi and restoring pulse, is a common medicine for critical emergencies in traditional Chinese Medicine. Interestingly, our previous study established a spleen-deficiency rat model and verified the potency of SMY formula in curing spleen-deficiency rats. Our goal herein was to explore whether SMY can modulate the composition of intestinal flora and alleviate spleen-deficiency in rats. Methods This experiment was randomly divided into three groups, namely the normal control group (NC), model control group (MC), and the Shengmai Yin group (SMY). After the treatment, the weight and symptom indexes of the rats were recorded, histological changes in the colon were observed, levels of serum D-xylose, gastrin (GAS), and vasoactive intestinal peptide (VIP) were measured, and gut microbiota profiling was conducted by 16S rRNA sequencing. Results The body mass of the spleen-deficiency model rats significantly decreased compared with that of the NC group, and SMY treatment significantly increased body mass compared with the MC group (P < 0.01). Colon histopathology revealed that SMY treatment alleviated colonic mucosal damage in spleen-deficiency rats. The serum levels of D-xylose and gastrin (GAS) were significant increased by SMY (P < 0.05, P < 0.01), and vasoactive intestinal peptide (VIP) was reduced by SMY (P < 0.01) compared with MC. Furthermore, alpha diversity was significantly decreased in the model rats compared to the normal rats (P < 0.05) and increased with SMY treatment (P < 0.01). The most abundant phyla were Firmicutes and Bacteroidetes, followed by Proteobacteria, Verrucomicrobia, and Actinobacteria. At the genus level, there was a lower relative abundance of Lactobacillus, Bacteroides, Akkermasia, and Allobaculum, and a higher relative abundance of Lachnospiraceae NK4A 136 group, Ruminococcaceae UCG-014, and Sphingomonas in the MC group. The relative abundance of Actinobacteria, Alistipes, Bifidobacterium, Bifidobacterium, Bifidobacteriaceae, Lachnospiraceae NK4A136group, Lactobacillus, Lactobacillaceae, Bacilli, Verrucomicrobiae, and Akkermansia were significantly abundant in the treatment groups, and thus may be singled out as potential biomarkers for SMY in the treatment of spleen deficiency. In addition, analysis on the correlation between species and physicochemical indexes showed that the abundance of Parasutterella was negatively correlated with the change in GAS, and positively correlated with the change in VIP (P < 0.01). Conclusion Our findings have provided preliminary evidence that modulating the gut microbiota may play a role in the treatment of spleen deficiency with SMY. However, further studies are needed to clarify the mechanism by which SMY regulation of related gut microbiota occurs.

Vein Occlusion

Branch retinal vein occlusion (BRVO) is a common retinal vascular disorder leading to visual impairment. Currently, the general strategies for BRVO are symptomatic therapies. Cardiovascular aspects are essential risk factors for BRVO. The traditional Chinese medicine hexuemingmu (HXMM), consisting of tanshinol and baicalin, dilates the vasculature and accelerates microcirculation. Therefore, the aim of this study was to determine the efficacy and possible mechanism of HXMM in a BRVO rat model established by laser photocoagulation. Successful BRVO rat models were treated with different doses of HXMM. Fundus photography and fluorescein fundus angiography (FFA) of the animals were applied. The retinal layers were measured by optical coherence tomography (OCT). Full-field electroretinography (ffERG) was applied to evaluate the retinal function. The ear vein flow velocity was measured via a microcirculation detector. The expression of the vascular endothelial growth factor (VEGF-α) was measured via western blotting and immunofluorescent staining. Our study found that retinal edema predominantly occurred in the inner nuclear layer (INL) and outer nuclear layer (ONL). The retinal edema of the treated groups was significantly relieved in the early stage of BRVO as visualized via OCT detection and HE staining. The amplitudes of the b wave and oscillatory potentials (OPs) waves of ffERG in the treated groups were increased compared with those of the control group at several detection points (3, 5, 7, 10, 14, and 21 d postocclusion). The expression of VEGF-α was reduced in the treated groups at an early stage of BRVO. Furthermore, the ear vein flow velocity of the HXMM treatment groups was faster than that of the control group. Thus, our study indicates that the traditional Chinese medicine HXMM could ameliorate retinal edema and rescue the retinal structure and function in BRVO models through promoting occluded vein recanalization, improving microcirculation, and regulating the expression of VEGF-α.

Abstract The purpose of this study was to investigate whether the Dictyophora echinovolvata spore polysaccharides (DESP) affect the immunity in immunocompromised mice induced by cyclophosphamide (CTX). The healthy female Kunming mice were randomly divided into six groups, including a normal control (NC) group, a positive control group, a model control (MC) group, and three groups treated with low-, intermediate-, and high-dose polysaccharide, respectively. A series of immunoregulatory properties were determined, including humoral and cellular immunity, immune function, and immune factors of mononuclear macrophages. Compared with NC and MC groups, treatment with DESP significantly increased the spleen index and decreased the thymus index; increased the serum concentrations of immunoglobulin (Ig)A, IgG, IgM, hemolysin, IL-1β, and IL-2; delayed the allergic reaction; and improved the splenic lymphocyte transformation ability; and enhanced the phagocytosis of macrophages and the ability to secrete IL-6, TNF-α, caspase-1, and NO with DESP supplementation. These results indicated that DESP might have a good regulatory effect on CTX-induced immunodeficiency in mice, adjust the body’s immune imbalance, and improve the symptoms of low immunity.
