Abstract
Acute lung injury (ALI) greatly threatens human health worldwide. P-selectin is a potential target for the treatment of acute inflammatory diseases, and natural polysaccharides exhibit high-affinity for P-selectin. Viola diffusa, a traditional Chinese herbal, shows strong anti-inflammatory effects, but pharmacodynamic substances and underlying mechanisms are still unclear. In this study, a galactoxylan polysaccharide (VDPS) derived from Viola diffusa was isolated and characterized, evaluated the protective effect on LPS induced ALI and underlying mechanism. VDPS significantly alleviated LPS-induced pathological lung injury, and decreased the numbers of total cells and neutrophils as well as the total protein contents in the bronchoalveolar lavage fluid (BALF). Moreover, VDPS reduced proinflammatory cytokine production both in BALF and lung. Interestingly, VDPS significantly restrained the activation of NF-κB signaling in the lung of LPS-exposed mice, but it cannot inhibit LPS-induced inflammation in human pulmonary microvascular endothelial cells (HPMECs) in vitro. Additionally, VDPS disrupted neutrophil adhesion and rolling on the activated HPMECs. VDPS cannot impact the expression or cytomembrane translocation of endothelial P-selectin, but remarkably interrupt the binding of P-selectin and PSGL-1. Overall, this study demonstrated that VDPS can alleviate LPS-induced ALI via inhibiting P-selectin-dependent adhesion and recruitment of neutrophils on the activated endothelium, providing a potential treatment strategy for ALI.

Abstract
P-selectin is a promising therapeutic target for acute inflammation-related diseases, and interest has been growing in the search for high-affinity glycoconjugate ligands that can target the initial P-selectin-mediated recruitment of neutrophils to the site of inflammation. In our previous study, we isolated a water-soluble polysaccharide (BCPS) from Bupleurum chinense and showed that it exhibits anti-inflammatory effect by antagonizing P-selectin-mediated adhesion of HL-60 cells to CHO-P cells. In this study, we prepared a P-selectin-based affinity chromatography medium and used it to purify the P-selectin-binding moiety of BCPS. The purified P-selectin-binding moiety of BCPS, designated as BCPS-m, was mainly composed of arabinose, galactose and glucose, and had a relative molecular weight of 3600 Da. The backbone of BCPS-m was composed of 1,5-linked arabinose, 1,4-linked and 1,4,6-linked glucose, and with branched 1-linked glucose or galactose terminal. BCPS-m could disrupt the P-selectin-mediated binding of HL-60 cells to CHO-P cells (CHO cells that stably expressed an exogenous P-selectin). It also blocked the interaction between P-selectin and its physiological ligand PSGL-1 significantly, resulting in much greater reduction (77%) in P-selectin-PSGL-1 binding than that caused by BCPS (35%). The data suggested that BCPS-m could be the key P-selectin-binding moiety of BCPS, and that it may be a better P-selectin antagonist than BCPS.

Abstract
CONTEXT Diabetic liver injury is a serious diabetic complication. The alterations of intestinal microbiota play an important role in induction and promotion of liver injury progression. Physalis alkekengi L. var. francheti (Mast.) Makino (Solanaceae) has been used as a water decoction for treating diabetes. OBJECTIVE To study the effects of a polysaccharide (PPSB) from Physalis alkekengi var. francheti on liver injury and intestinal microflora in type-2 diabetic mice. MATERIALS AND METHODS Streptozotocin (160 mg/kg) was injected i.p. for 3 days to build model. The diabetic mice were randomly divided into four groups together with control group (10 mice in each group). The doses of PPSB were 50 and 100 mg/kg, respectively. After 5 weeks administration, level of blood glucose, ALT and AST were measured. Alterations of intestinal microflora, and protein expression of TGF-β1, TNF-α and DCN were detected. RESULTS Level of blood glucose decreased from (25.38 ± 2.21) mmol/L to (18.01 ± 2.53) mmol/L, ALT and AST decreased to (24.67 ± 4.86) U/L and (30.84 ± 7.50) U/L in PPSB-H group. Lactobacillus, Clostridium butyricum, and Bacteroides increased remarkably with increasing concentration of PPSB, but Enterobacter was inhibited. The relative expression of TGF-β1 and TNF-α decreased to (0.70 ± 0.17) and (0.39 ± 0.06), and the expression of DCN increased to (0.65 ± 0.13). DISCUSSION AND CONCLUSIONS Probiotics have been promoted by PPSB, and protein expressions have been modulated in the progression of liver injury. PPSB could be used as a natural agent for treating diabetic liver injury and intestinal microflora imbalance.

Abstract
CONTEXT P-selectin is a promising target for inflammatory-related diseases. Polysaccharides are the active ingredients of Sanguisorba officinalis L. (Rosaceae) responsible for its anti-inflammatory activities; however, the molecular mechanism is not clear yet. OBJECTIVE This study evaluates the effects of polysaccharides (SOPs) from Sanguisorba officinalis on their antagonistic function against P-selectin-mediated leukocyte adhesion. MATERIALS AND METHODS The antagonistic function of SOPs was investigated by flow cytometry and static adhesion assay at the concentrations of 25 and 100 μg/ml. The dynamic interaction between HL-60 cells and CHO-P cell monolayer treated with SOPs (25 and 100 μg/ml) was analyzed in a parallel plate flow chamber, and quantitatively calculated by ImageJ software (NIH, Bethesda, MD). In vitro protein binding assay was carried out to evaluate the blocking effects of SOPs (25 and 100 μg/ml) on the interaction between P-selectin and PSGL-1. RESULTS SOPs-treatment (100 μg/ml) significantly reduced the percentage of HL-60 cells binding to P-selectin (p < 0.01) determined by flow cytometry. In addition, SOPs (25 and 100 μg/ml) markedly blocked the adhesion between HL-60 cells and CHO-P cells under static condition, and the inhibitory rates reached 39.9% and 71.2%, respectively. Compared with the positive control group, SOPs-treatment (25 and 100 μg/ml) significantly reduced the percentage of HL-60 cells rolling on CHO-P cell monolayers by 43.5% and 75.2%, respectively. Protein binding assay showed the interaction between P-selectin and PSGL-1 was significantly blocked by SOPs. DISCUSSION AND CONCLUSION SOPs possess a significant antagonistic function against P-selectin-mediated leukocyte adhesion, and SOPs could be considered as a promising candidate for amelioration of inflammation-related diseases.

Abstract
P-selectin-mediated adhesion between endothelium and neutrophils is a crucial process leading to acute inflammatory injure. Thus, P-selectin has been considered as promising target for therapeutics of acute inflammatory-related diseases. In the present study, the water-soluble polysaccharides (BCPs) were isolated from Bupleurum chinense, and we evaluated their therapeutical effects on acute inflammatory injure and antagonistic function against P-selectin-mediated neutrophil adhesion. Our results showed that BCPs significantly impaired the leukocyte infiltration and relieve lung injury in LPS-induced acute pneumonia model. BCPs significantly blocked the binding of P-selectin to neutrophils and inhibited P-selectin-mediated neutrophils rolling along CHO-P cell monolayer. The result from in vitro protein binding assay showed a direct evidence indicating that BCPs-treatment significantly eliminated the interaction between rhP-Fc and its physiological ligand PSGL-1 at protein level. Together, these results provide a novel therapeutical strategy for amelioration of inflammation-related disease processes by polysaccharides from B. chinense.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Though inflammatory response is beneficial to body damage repair, if it is out of control, it can produce adverse effects on the body. Although purely western anti-inflammatory drugs, orthodox medicines, can control inflammation occurrence and development, it is not enough. The clinical efficacy of anti-inflammation therapies is unsatisfactory, thus the search for new anti-inflammation continues. Chinese Material Medica (CMM) remains a promising source of new therapeutic agents. CMM and herbal formulae from Traditional Chinese Medicine (TCM), unorthodox medicines, play an improtant anti-inflammatory role in multi-targets, multi-levels, and multi-ways in treating inflammation diseases in a long history in China, based on their multi-active ingredient characteristics. Due to these reasons, recently, CMM has been commercialized as an anti-inflammation agent which has become increasingly popular in the world health drug markets. Major research contributions in ethnopharmacology have generated vast amount of data associated with CMM in anti-inflammtion aspect. Therefore, a systematic introduction of CMM anti-inflammatory research progress is of great importance and necessity. AIM OF THE STUDY This paper strives to describe the progress of CMM in the treatment of inflammatory diseases from different aspects, and provide the essential theoretical support and scientific evidence for the further development and utilization of CMM resources as a potential anti-inflammation drug through a variety of databases. MATERIAL AND METHODS Literature survey was performed via electronic search (SciFinder®, Pubmed®, Google Scholar and Web of Science) on papers and patents and by systematic research in ethnopharmacological literature at various university libraries. RESULTS This review mainly introduced the current research on the anti-inflammatory active ingredient, anti-inflammatory effects of CMM, their mechanism, anti-inflammatory drug development of CMM, and toxicological information. CONCLUSION CMM is used clinically to treat inflammation symptoms in TCM, and its effect is mediated by multiple targets through multiple active ingredients. Although scholars around the world have made studies on the anti-inflammatory studies of CMM from different pathways and aspects and have made substantial progress, further studies are warranted to delineate the inflammation actions in more cogency models, establish the toxicological profiles and quality standards, assess the potentials of CMM in clinical applications, and make more convenient preparations easy to administrate for patients. Development of the clinically anti-inflammatory drugs are also warranted.

Abstract
Although neutrophils play important roles in host defense, sometimes they contribute to inflammation-related tissue injuries. Thus, restriction of their recruitment to the inflammatory sites is a promising strategy in the amelioration of inflammatory disease. The previous studies reported the anti-inflammatory effects of Bupleurum chinense, but the active ingredients and possible mechanism are still unclear. Here, we isolated water-soluble polysaccharides (BCPs) from B. chinense, to evaluate its anti-inflammatory effects and possible mechanism. The present results showed that BCPs significantly impaired the in vivo neutrophil infiltration, as well as the migration capacity of dHL-60 cells in vitro. In addition, BCPs inhibits chemoattractant fMLP-induced activation and clustering of β2 integrin. BCPs impacted fMLP-induced actin polymerization and the activation of cytoskeleton regulatory molecules, Vav1 and Rac1. Together, BCPs significantly impacted recruitment and migration of neutrophils by blocking chemoattractant receptor-mediated functions, and it possesses a potential as novel anti-inflammatory drug.
