Aim To study the antitumor and immunological regulation effects of ardipusilloside-Ⅰ(ADS-Ⅰ) on tumor-bearing mice of S180, H22, EAC and L1210. Methods The tumor-bearing mouse model was made through injecting cancer cells in the right limb oxter(or in abdominal cavity), and the mice were administrated orally with ADS-Ⅰfor 8 days. Then we detached the tumor and counted the inhibition rate of tumor growth. Incorporation of ()~3H-TdR was used to assess the proliferation of T spleen lymphocyte cells; phagocytosis of abdominal cavity macrophage was measured with the method of chicken red blood cells. Results ADS-Ⅰ was proved to be effective on the tumor-bearing mice of S180, H22 and EAC, and the maximal inhibition rate of the dose of 100 mg?kg~(-1) was 38.7%, 48.6% and 50.0%, respectively;ADS-Ⅰ promoted the proliferation of T spleen lymphocyte cells,and strengthened the phagocytosis of macrophage in the tumor-bearing mice significantly. Conclusion ADS-Ⅰ can inhibit the growth of transplanted tumor,and improve the immunological function of tumor-bearing mice.

This study aimed at the molecular mechanism of Cordyceps sinensis polysaccharide-A(CPS-A) on angiotensin (Ang Ⅱ)-induced injury of L02 cells.The effect of AngⅡ and CPS-A on the proliferation of L02 cells was analyzed by MTT assay.PCR,Real-Time PCR and Western blot were also employed to determine the expression of IL-1β,AT1R,AT2R,NF-κB p65,TNFα and other inflammatory factors at mRNA and protein levels.The results showed that Ang Ⅱ and CPS-A could inhibit the proliferation of L02 cells by 1 × 10-5 mol/L and 200 μg/ mL,respectively.PCR,Real-Time PCR and Western blot showed that CPS-A could significantly down-regulate IL-1 β,TNF-α,NF-κB and AT1R.CPS-A has a good protective effect on AngⅡ-induced L02 cell injury.

Objective:To develop a method of quantitative analysis of multi-components by single marker(QAMS)for the determi-nation of five constituents(ephedrine hydrochloride,amygdalin,liquiritin, baicalin and ammonium glycyrrhizinate)in Xiao'er Magan granule. Methods:Amygdalin was used as the internal reference substance, and the relative correlation factors(RCF) of ephedrine hydrochloride,liquiritin,baicalin and ammonium glycyrrhizinate to amygdalin were calculated and evaluated. The contents of the five constituents were determined by the external standard method(ESM) and QAMS,respectively. The content results determined by the two methods were compared and the feasibility of QAMS method was verified. Results:The RCF between amygdalin and the other con-tents was 1.237,1.318,1.327 and 0.884,respectively. There were no significant differences in the results between QAMS and ESM with the relative errors less than 0.3%. Conclusion:The QAMS method is accurate and feasible for the simultaneous determination of Xiao'er Magan granule.

Objective UPLC-Q-TOF-MS integrated molecular network strategy was used to rapidly analyze and identify the chemical components of Yuye detoxification Particle. Methods The secondary mass spectrometry data of compounds were obtained using mass spectrometry scanning in both positive and negative ion mode. The similarity of MS/MS fragmentation patterns was calculated to create the global natural product social molecular networking (GNPS) platform. The major components in Yuye detoxification Particle were quickly identified according to the molecular clusters with similar structures in GNPS. Manual analysis and identification of other compounds were performed according to the mass fragment ion information of the primary and secondary mass spectrum data and related references by using the molecular feature extraction (MFE) function of Agilent Masshunter Qualitative Analysis workstation and traditional Chinese Medicine composition database (TCM-DATA). Results A total of 89 compounds in Yuye detoxification Particle were identified by LC-MS,including 22 phenoliacids,21 flavonoids and their glycosides,6 iridoid glycosides,28 triterpenoid saponins and 12 other types of ingredients. Conclusion UPLC-Q-TOF-MS/MS integrated molecular network technology can be used for rapid and systematic identification of chemical components of Yuye detoxification Particle,which provides theoretical basis for its quality control and clinical application. The established molecular network can provide reference for rapid qualitative analysis of components of traditional Chinese medicine compound.
