Coptidis Rhizoma-Euodiae Fructus has been widely used for the treatment of digestive diseases since Song Dynasty, and therapeutic efficacy is very obvious. Modern research found that alkaloids are the main bio-active constituents, and some of their contents have striking difference after compatibility of the two herbs. The Chinese medicine pair (CMP) has extensive biological activities, such as the effect of gastrointestinal effect, anti-tumor, lowering the blood pressure and blood fat and so on. And some action mechanism of CMP also got partial demonstration. This paper mainly summarized the bio-active constituents, compatibility effects, action mechanism and clinical applications of the CMP, which can provide a basis for further research and development of the CMP.

Objective To verify whether miR-498 can inhibit A549 cell migration and invasion by down-regulating FOXM1.Methods miR-498 mimic and miR-NC were transfected into A549 cells.Wound healing and Transwell method were employed to test the migratory ability and invasion ability of A549 cells;Western blot was used to detect the expressions of COL1A1,COL1A5 and FOXM1 in A549 cells.Luciferase assay was used to confirm whether FOXM1 is the target gene of miR-498.Results Compared with those in the control group,the expressions of COL1A1,COL1A5 and FOXM1 were decreased,and the migration and invasion abilities of A549 cells were decreased in the miR-498 group (both P<0 .01 ).The luciferase activity of the FOXM1-3′-UTR plasmid was significantly suppressed by miR-498 (P<0 .05 );over-expression of FOXM1 could reverse the effect of miR-498 on A549 cells.Conclusion miR-498 inhibits A549 cell migration and invasion by down-regulating FOXM1.

OBJECTIVETo investigate the effect of SIRT6/NF-κB signal axis in delaying hematopoietic stem/progenitor cell senescence with ginsenoside Rg1, in order to provide theatrical and experimental basis for looking for methods for delaying HSC senescence.

METHODSca-1 + HSC/HPC was isolated by magnetic cell sorting (MACS) and divided into five groups: the normal control group, the aging group, the positive control group, the Rg1 anti-senescence group, and the Rg1-treated group. Senescence-associated β-galactosidase (SA-β-Gal) staining, cell cycle analysis and hemopoietic progenitor cell mix (CFU-Mix) were adopted to determine the effect Rg1 in delaying or treating Sca-1 + HSC/HPC senescence biology. The mRNA and protein of senescence regulation molecules SIRT6 and NF-KB were examined by realtime fluorescence quantitative PCR (FQ-PCR) and western blotting.

RESULTCompared with the senescence group, the Rg1 anti-senescence group and the Rg1-treated group showed lower percentage in SA-β-Gal-stained positive cells, decreased cell proportion in G1 phase, increased number of CFU-Mix, up-regulated in SIRT6 mRNA and protein expression, down-regulation in NF-KB mRNA and protein expression. The Rg1 anti-senescence group showed more evident changes in indexes than the Rg1-treated group.

CONCLUSIONRg, may inhibit Sca-1 + HSC/HPC senescence induced by t-BHP by regulating SIRT6/NF-KB signal path.

OBJECTIVETo establish a method for studying efficacious materials of traditional Chinese medicines from an overall perspective.

METHODCarthamus tinctorius was taken the example. Its major components were depleted by preparing liquid chromatography. Afterwards, the samples with major components depleted were evaluated for their antioxidant effect, so as to compare and analyze the major efficacious materials of C. tinctorius with antioxidant activity and the contributions.

RESULTSeven major components were depleted from C. tinctorius samples, and six of them were identified with MS data and control comparison. After all of the samples including depleted materials are compared and evaluated for their antioxidant effect, the findings showed that hydroxysafflor yellow A, anhydrosafflor yellow B and 6-hydroxykaempferol-3, 6-di-O-glucoside-7-O-glucuronide were the major efficacious materials.

CONCLUSIONThis study explored a novel and effective method for studying efficacious materials of traditional Chinese medicines. Through this method, we could explain the direct and indirect contributions of different components to the efficacy of traditional Chinese medicines, and make the efficacious material expression of traditional Chinese medicines clearer.

Objective To compare the effects of hepatic vein occlusion with tourniquet and Satinsky clamp in reseeting liver tumor involving the second hepatic portal.Methods From Jan 2003 to Jun 2006,180 patients underwent major liver resection with the selective hepatic vascular exclusion (SHVE).According to methods of hepatic vein occlusion,they were divided into two groups:Occlusion with tourniquet(tourniquet group,n=95)and occlusion with Satinsky clamp(Satinsky clamp group,n= 85).In tourniquet group,the hepatic veins were encircled and occluded with tourniquet,and in Satinsky clamp group,the hepatic veins were not encircled and clamped directly with Satinsky clamp.Data regarding the intraoperative and postoperative courses of the patients were analyzed.Results There was no difference between the two groups regarding the operating time,ischemia time,intraoperative blood loss and postoperative complications rate.The dissecting time of hepatic veins was significantly shorter in Satinsky group(6.2?2.4 min vs 18.3?6.2 min).lu the tourniquet group,five hepatic veins(one fight hepatic vein and four common trunk of left-middle hepatic veins)could not be dissected and encircled because of the tumors involving the cava hepatic junction.Another patient's common trunk of left-middle hepatic vein was inadvertently lacerated during the dissection.Hepatic veins in these 6 patients were occluded with Satinsky clamp successfully.Conclusion Occlusion with Satinsky clamping is safer and easier procedure than tourniquets in the resection of liver tumor involving the second porta hepatis.

Objective To investigate the role of CD4~+CD25~+ Treg cells on the pathogenesis of ankylos- ing spondylitis(AS), and to study the machanism of tumor necrosis factor(TNF)-?blocker on the treatment of AS by detecting the number of CD4~+D25~+ Treg cells before and after the treatment. Methods The diagno- sis of 10 AS patients was made based on the 1984 modified New York criteria. The patients received subcuta- neou injection of recombinant human tumor necrosis factor receptor-Fc fusion protein(rhTNFR-Fc)(etaner- cept)50 mg weekly for 8 weeks and 10 heathy subjects were enrolled for control. The mononuclear cells were isolated from peripheral blood in beth patients and controls. The number of CD4~+CD25~+ T cells and CD4~+ CD25~(high)T cells and the expression of CTLA-4. were detected by flow cytometry. Results The proportion of CD4~+CD25~+ T cells(24?19)% in total CD4~+ T lymphocytes of peripheral blood and CD4~+CD25~(high)T/CD4~+ T (6?6)% from AS patients before treated with rhTNFR-Fc was higher than that in healthy volunteers and AS patients after treatment(P
