Abstract
One purified neutral polysaccharide fraction was obtained from the rhizome of Polygonatum sibiricum by DEAE ion exchange and gel chromatography. Structure elucidation was performed by methanolysis, methylation, FT-IR, and NMR. The results indicated that PSP-NP was composed of 1,4-β-D-Gal,1, 4, 6-β-D-Gal, T-α-D-Man,1, 4-α-D-Glc, and T-α-D-Glc with a molecular weight of 43.0 kDa. We supplied this polysaccharide to aged mice and found it is of benefits to intestinal functions, as indicated by better tissue integrity and motility, improved oxidative stress and inflammation, reduced intestinal permeability and serum LPS level, as well as balanced gut microbial composition and short-chain fatty acids production. These results display a novel Polygonatum sibiricum polysaccharide to improve the intestinal function of aged mice, which provides pieces of evidence for its further development and utilization.

Abstract
An inulin (CPPF), isolated from a traditional Chinese herbal medicine Codonopsis pilosula, was characterized and demonstrated with potential prebiotic activity in vitro before. Based on its non-digested feature, the intestinal mucosa and microbiota modulatory effects in vivo on immunosuppressed mice were investigated after oral administration of 200, 100 and 50 mg/kg of CPPF for 7 days. It was demonstrated that the secretions of sIgA and mucin 2 (Muc2) in ileum were improved by CPPF, and the anti-inflammatory activities in different intestine parts were revealed. The intestine before colon could be the target active position of CPPF. As a potential prebiotic substance, a gut microbiota restorative effect was also presented by mainly modulating the relative abundance of Eubacteriales, including Oscillibacter, unidentified Ruminococcus and Lachnospiraceae after high-throughput pyrosequencing of V4 region of 16S rRNA analysis. All these results indicated that this main bioactive ingredient inulin from C. pilosula was a medicinal prebiotic with enhancing mucosal immune, anti-inflammatory and microbiota modulatory activities.

Abstract
BACKGROUND Codonopsis pilosula and C. tangshen are both plants widely used in traditional Chinese medicine. Polysaccharides, which are their primary active components, are thought to be important in their extensive use. In this study, two neutral polysaccharide fractions of C. pilosula (CPPN) and C. tangshen (CTPN) were obtained by fractionation on a DEAE-Sepharose column and characterized. RESULTS It was confirmed that the neutral polymers CPPN and CTPN were β-(2,1)-linked inulin-type fructans with non-reducing terminal glucose, and degree of polymerization (DP) of 19.6 and 25.2, respectively. The antioxidant and prebiotic activities in vitro were assayed based on IPEC-J2 cell lines and five strains of Lactobacillus. Results indicated that the effects of CPPN and CTPN were increased antioxidant defense in intestinal epithelial cells through enhanced cell viability, improved expression of total antioxidant capacity, glutathione peroxidase, superoxide dismutase and catalase, and reduced levels of malondialdehyde and lactic dehydrogenase. The prebiotic activity of CPPN and CTPN was demonstrated by the promoting effect on Lactobacillus proliferation in vitro. The different biological activities obtained between the two fractions are probably due to the different DP and thus molecular weights of CPPN and CTPN. CONCLUSION The inulin fractions from C. pilosula and C. tangshen were natural sources of potential intestinal antioxidants as well as prebiotics, which will be valuable in further studies and new applications of inulin-containing health products. © 2020 Society of Chemical Industry.

Abstract
PURPOSE This paper aims to observe the expressions of VEGF and MMP-2 in patients with nasopharyngeal carcinoma treated by nimotuzumab combined with cisplatin. METHODS Altogether, 104 patients with nasopharyngeal carcinoma treated in our hospital from April 2014 to August 2016 were selected as research subjects. Among them, 50 patients treated with cisplatin were divided into a control group and 54 patients treated with nimotuzumab combined with cisplatin were divided into an observation group. The two groups of patients were compared in terms of efficacy after treatment and incidence of adverse reactions. Changes of serum VEGF and MMP-2 concentrations before and after treatment were detected using enzyme-linked immunosorbent assay (ELISA), and the 3-year overall survival (OS) of patients was observed. RESULTS Compared with the control group, patients in the observation group had significantly higher total remission rate (RR) (P < 0.05) and significantly lower incidence of adverse reactions (P < 0.05). Before treatment, there was no significant difference between the observation and control groups in the concentrations of VEGF and MMP-2 (P > 0.05). After treatment, the concentrations in the two groups were significantly lower than those before treatment (P < 0.05), and the concentrations in the observation group were significantly lower than those in the control group (P < 0.05). There was no significant difference in the 3-year OS between the observation and control groups (P > 0.05). CONCLUSIONS Nimotuzumab combined with cisplatin could improve the conditions of patients with nasopharyngeal carcinoma. After treatment, the expression of VEGF and MMP-2 decreased significantly. We speculated that it improves the survival rate of patients by reducing the expression of VEGF and MMP-2.

Abstract
Preeclampsia (PE) may induce gestational failure, threatening a significant number of pregnant women. Recently, microRNAs (miRNAs) have been reported to participate in PE progression, whereas the precise functions and potential mechanisms of miR-20b in placental trophoblast cells as well as in PE progression remain poorly understood. In the present study, real-time quantitative polymerase chain reaction (RT-qPCR) analysis was used to detect expressions of miR-20b and myeloid cell leukemin- 1(MCL-1) mRNA. Cell viability was investigated by cell counting kit-8(CCK-8) assays. Cell invasion and migration abilities were determined by Transwell assays. Western blot was performed to detect MCL-1 protein expressions. The interaction between miR-20b and MCL-1 was investigated by bioinformatics analysis and luciferase activity assay. The results of the study demonstrated that miR-20b was highly expressed in placental tissues of patients with PE. Moreover, miR-20b overexpression inhibited HTR8/ SVneo cell proliferation, invasion and migration. Furthermore, MCL-1 was targeted by miR-20b, and MCL-1 restoration could partially attenuate the effect of miR-20b on HTR8/SVneo cells. In conclusion, the results indicate that miR-20b may contribute to PE through inhibiting proliferation, invasion and migration of placental trophoblast cells by targeting MCL-1. Therefore, miR-20b may be used as a notable biomarker for the diagnosis, prevention, and treatment of PE. MiR-20b targeting MCL-1 deserves further investigation in order to explore their potential role in PE.

Abstract
Surfactants can improve the hydrophobicity of poorly water-soluble drugs and increase the stability of microparticles by reducing surface tension. This study describes that surfactant-engineered florfenicol instant microparticles (FIMs) increase bioavailability through a micellar solubilization mechanism. The FIMs were prepared by a modified emulsification method, and the optimal prescription was obtained by a combination of single factor investigation and response surface methodology. The microparticles prepared in this study reduce the polymer materials while increasing the drug content. FIM has a smaller particle size and modification of poloxamer, resulting in better solubility and higher bioavailability. The in vitro solubility of FIM is 1.43 times higher than that of the bulk drug, and the dissolution equilibrium can be achieved in 10 minutes. Compared with florfenicol, FIM showed a decrease in Tmax in the plasma concentration curve, with a peak concentration of 1.43 times and an area of 1.41 times. Considering the advantages of in vitro/in vivo performance and ease of preparation, FIMs may have great application prospects in pharmacy research.

Abstract
In this study, an acidic polysaccharide from Codonopsis pilosula Nannf. var. modesta (Nannf.) L. T. Shen (WCP-I) and its main fragment, WCP-Ia, obtained after pectinase digestion, were structurally elucidated and found to consist of a rhamnogalacturonan I (RG-I) region containing both arabinogalactan type I (AG-I) and type II (AG-II) as sidechains. They both expressed immunomodulating activity against Peyer’s patch cells. Endo-1,4-β-galactanase degradation gave a decrease of interleukine 6 (IL-6) production compared with native WCP-I and WCP-Ia, but exo-α-l-arabinofuranosidase digestion showed no changes in activity. This demonstrated that the stimulation activity partly disappeared with removal of β-d-(1→4)-galactan chains, proving that the AG-I side chain plays an important role in immunoregulation activity. WCP-Ia had a better promotion effect than WCP-I in vivo, shown through an increased spleen index, higher concentrations of IL-6, transforming growth factor-β (TGF-β), and tumor necrosis factor-α (TNF-α) in serum, and a slight increment in the secretory immunoglobulin A (sIgA) and CD4+/CD8+ T lymphocyte ratio. These results suggest that β-d-(1→4)-galactan-containing chains in WCP-I play an essential role in the expression of immunomodulating activity. Combining all the results in this and previous studies, the intestinal immune system might be the target site of WCP-Ia.

Abstract
The antioxidant effect of salidroside has been proven, but its role in liver injury is poorly understood. In this study, we aimed to evaluate the protective effects and mechanism of salidroside on liver injury induced by carbon tetrachloride (CCl4) in vivo. Mice were pretreated with salidroside (60 mg/kg, intraperitoneally injected, i.p.) once per day for 14 consecutive days and then administered with CCl4 (15.95 g/kg, i.p.) for 24 h to produce a liver injury model. Salidroside attenuated hepatic transaminase elevation in serum and ameliorated liver steatosis and necrosis, thereby suggesting its protective effect on the liver. Salidroside antagonized CCl4-induced toxicity by equilibrating antioxidation system, thereby inhibiting reactive oxygen species accumulation, and restoring mitochondrial structure and function. Salidroside exerts antioxidant and liver-protective effects by selectively inhibiting the activation of genes, including growth arrest and DNA -damage-inducible 45 α (Gadd45a), mitogen-activated protein kinase 7 (Mapk7), and related RAS viral oncogene homolog 2 (Rras2), which induce oxidative stress in the mitogen-activated protein kinase pathway. These results revealed that salidroside can protect the liver from CCl4-induced injury by resisting oxidative stress and protecting mitochondrial function.

Abstract
Based on previous studies about microflora regulation and immunity enhancement activities of polysaccharides from Codonopsis pilosula Nannf. var. modesta (Nannf.) L. T. Shen (CPP), there is little study on intestinal mucosal immunity, which is a possible medium for contacting microflora and immunity. In the present study, the BALB/c mice were divided into five groups (eight mice in each group), including a normal group (Con), a model control group (Model), and model groups that were administered CPP (50, 100, 200 mg/kg/d) orally each day for seven days after intraperitoneal injection of 60 mg/kg BW/d cyclophosphamide (CP) for three days. CPP recovered the spleen index and restored the levels of IFN-γ, IL-2, IL-10, as well as serum IgG. In addition, it elevated ileum secretory immunoglobulin A (sIgA), the number of Lactobacillus and acetic acid content in cecum. These results indicated that CPP plays an important role in the protection against immunosuppression, especially mucosa immune damage, and the inhibition of pathogenic bacteria colonization, which could be considered a potential natural source of immunoregulator.

Abstract
The purpose of this study was to optimize the extraction process of phloridzin from Lithocarpus polystachyus Rehd. leaves using response surface methodology and to determine the antioxidant capacity of the extract. A Box-Behnken design was used to analyze the effects of ethanol concentration, liquid-solid ratio, soak time and extraction time on the extraction yield of phloridzin. The content of phloridzin was determined by high-performance liquid chromatography. To assess the antioxidant capacity of the extract, three in vitro test systems were used (1,1-,diphenyl-2-picrylhydrazyl, hydroxyl radical scavenging test and reduction force). The optimal parameters obtained by response surface methodology were a volume fraction of ethanol of 64%, a liquid-solid ratio of 37:1, a soaking time of 35 h and a sonication time of 38 min. The proportion of the extraction of phloridzin from L. polystachyus under these industrial process conditions was 3.83%. According to the obtained results, response surface methodology could be suggested as an adequate model for optimizing the extraction process of phloridzin from L. polystachyus. Ultrasound extraction significantly increased the extraction rate of phloridzin, which could be used as an antioxidant in pharmaceutical and food products.

Abstract
Chinese patent medicines play an important role in veterinary clinical use. The aim of this study is to research the anti-infection effect of Chinese patent medicine "Wuhuanghu" for the treatment of porcine infectious pleuropneumonia and to evaluate the safety of "Wuhuanghu" in order to provide a comprehensive understanding of its toxicity. The anti-infection results showed that the treatment with "Wuhuanghu" could significantly inhibit pneumonia and decrement of the pneumonia in high, medium and low doses of "Wuhuanghu" groups were 70.97%, 61.29% and 58.06% respectively. The acute toxicity test showed that rats in the highest group (5000mg/kg) had no death and no abnormal response, suggesting the LD50 of "Wuhuanghu" was more than 5000mg/kg. The subchronic toxicity study showed that hematology indexes in all groups had no obvious differences; blood biochemical index, only albumin and total cholesterol in middle and low doses of "Wuhuanghu" groups were significantly decreased when compared with control group. The clinical pathology showed that the target organ of "Wuhuanghu" was liver. The safety pharmacology study indicated that "Wuhuanghu" had no side effects on rats. In conclusion, "Wuhuanghu" has therapeutic and protective effects to porcine infectious pleuropneumonia in a dose-dependent manner and "Wuhuanghu" is a safe veterinary medicine.

Abstract
The effects of acute and subacute toxicity of 1,8-cineole in Kunming mice were studied. After acute oral administration, the LD50 value (95% CL) was 3849 mg/kg (3488.8~4247.1 mg/kg). In the subacute toxicity study, there were no significant differences in body weight and relative organ weight between the control group and 1,8-cineole treatment groups. The histopathological examinations showed that granular degeneration and vacuolar degeneration appeared in liver and kidney tissue after administration of high dose of 1,8-cineole. Under electron microscopy, a series of ultrastructural changes were observed: The electron microscopy assays indicated that the influence of 1,8-cineole on the target organ at the subcellular level were mainly on the mitochondria, endoplasmic reticulum and other membrane type structure of liver and kidney.

Abstract
The objective of this study was to evaluate the immunomodulatory effects of cinobufagin (CBG) isolated from Chan Su (Venenum Bufonis) in vitro. In this paper, our results show that CBG significantly stimulated cell proliferation of splenocytes and peritoneal macrophages (PMΦ) and markedly enhanced the phagocytic activation of PMΦ. CBG also significantly increased CD4(+)CD8(+) double-positive T-cell populations and the percentage of S-phase cells of splenic lymphocytes. The levels of several Th1 cytokines, including interferon-γ and tumor necrosis factor-α, are significantly increased after CBG treatment, whereas the levels of the Th2 cytokine interleukin-4 and interleukin-10 are significantly decreased. As a result, the ratio of Th1/Th2 also increased. Taken together, these results indicated that CBG had potential immune system regulatory effects and suggested that this compound could be developed as a novel immunotherapeutic agent to treat immune-mediated diseases such as cancer.
