Tripterygium glycosides preparation which extracted from the traditional Chinese herb Tripterygium wilfordii (TWHY), was widely used to treat the autoimmune diseases. Previous works demonstrated that TWHF had potent anti-inflammatory and immunosuppressive properties. But the different quality and high incident rate of side effects of different manufactures inhibited its clinical application. Since TWHF had been generally known to play a therapeutical effect by synergism of multiple constituents, it was necessary to build the relationship between the HPLC fingerprint and bioactivity so as to ensure the quality safety and efficacy. The HPLC fingerprint showed that description and content of peaks from different manufactures were diverse. Only 11 common peaks were found. In this study, mice spleen cells stimulated by Con A were used to test the proliferation inhibition bioactivity of TWHF preparations, which were incubated with 30, 15, 7.5, 3.75, 1.88 and 0.94 mg x L(-1) TWHF preparations for 48 h. The results showed that mice spleen cells proliferation was inhibited by all TWHF preparations significantly compared with the control group, which suggested the TWHF preparations showed immune suppress activity. The TWHF preparations from 7 manufacture showed different IC50 value, which might belong to different contents which showed in the HPLC fingerprint. Moreover, a relationship between the HPLC fingerprint and the bioactivity were established to identify important constituents by grey relational analysis (GRA). The result showed that all the contents were relative with the IC50, especially No. 5 and 10 peaks, but No. 1 peak, which was proved to be triptolide, had few contribute to the inhibition of mice spleen cells proliferation. The study of relationship between the HPLC fingerprint and the IC50 by GRA could help to investigate mechanism of bioactive and provide an evidence for the quantification of multi-constituents.

Objective To screen the mimotopes ofpemphigus vulgaris (PV) antigen, desmoglein3 (Dsg3) with a phage-displayed random nonapeptide library, so as to update the knowledge on the patho-genesis of PV. Methods Recombinant fusion protein of extracellular domain 1-2 (EC1-2) of Dsg3 and glutathione transferase was expressed by E.coli BL21, and used to purify polyclonal autoantibody binding to recombinant EC 1-2 from the sera of patients with PV. Then, selected autoantibody was applied as a ligand for biopanning of a phage-displayed linear random nonapeptide library and circular random nonapeptide library. Monoclonal phages were selected by immunoscreening and tested with ELISA and competitive ELISA. Results After two rounds ofbiopanning, a population ofpeptide-displaying phages binding to autoan- tidody were highly enriched. Sixty individual phage clones selected by immunosereening were further sub-jected to screening with ELISA and competitive ELISA. Finally, three positive phage clones were obtained. As shown by ELISA and competitive ELISA, they reacted with serum from patients with PV but not with that from normal human controls, and blocked the interaction between patients' sera and recombinant fusion protein of EC1-2. Conclusion Three mimotopes closely associated with PV antigen were successfully selected from a phage-displayed random nonapeptide library.

Objective To determine which parameters of reverse remodeling of left ventricular could become the effective indexes in evaluating the short-term therapeutic effect of cardiac resynchronization therapy(CRT)in heart failure(HF)patients.Methods CRT was performed in 26 HF patients with dysfunctions of wall motion.Serial echocardiography was practiced at baseline,one and three months after CRT.The parameters including left atrial end-diastolic diameter(LADD),left ventrieular end-diastolic diameter(LVDD),end-diastolic volume (LVEDV),end-systolic volume(LVESV),ejection fraction(LVEF)were measured and compared before and after CRT therapy.Results At one and three months after CRT,respectively,CRT was associated with reduced LADD,LVDD,LVEDV,LVESV and improved LVEF and filling time compared with those at baseline.Moreover,all these parameters had better correlations with the activities of these patients.Conclusions LADD,LVDD,LVEDV,LVESV and LVEF could become the effective indexes in evaluating the short-term effect of CRT in HF patients.The reduced diameters and volumes of left atria and left ventricle are more sensitive parameters than the improved LVEF.

In this experiment, Hca-F or L615 elemene combo-TCV (H-TCV and L-TCV), H-TCV lysates, corynebacterium parvum (CP) were used to immunize 615 and Balb/c inbred mice, and their splenic DCs were prepared and pulsed in vitro with tumor cell lysates (H or L) and TCV lysates (TH or TL). The capacities of DCs to stimulate the proliferation of syngeneic nonadherent spleenic cells were tested with MTT assay. The results showed that the splenic DCs from normal mice in vitro pulsed with TH or TL could induced syngeneic noradherent splenic cells to proliferate (P＜0.01), while the H or L pulsed DCs could not. The splenic DCs from H-TCV or L-TCV or TH immunized mice re-pulsed in vitro with TH or TL exhibited stronger stimulating effects than the DCs from normal mice pulsed in vitro for the firth time pulsed with TH or TL (P＜0.01 or P＜0.05); The capacities of DCs to induce proliferation of syngeneic nonadherent splenic cells could be further enhanced by CP immunization, especially when were pulsed with TH (P＜0.01). Normal inbred 615 mice were transferred with DCs pulsed with lysates of elemene TCV (TDCs) or pulsed with lysates of Hca-F tumor cells (HDCs) on day 7 before challenged with lethal dose of live Hca-F cells, significant adoptive immunoprotective effects were seen, with 61.6% tumor inhibition rate and 25% survival in TDC adoptive transfer group. This study indicated that DCs might play a role in the mechanisms of active immunization and pulsing DCs with lysate of elemene combo TCV and isolating DCs from elemene combo TCV immunized mice were useful methods for DCs vaccine preparation.

Human xanthine oxidase is considered to be a target for therapy of hyperuricemia. Cichorium intybus is a Chinese plant medicine which widely used in Xinjiang against various diseases. In order to screen the inhibitors of xanthine oxidase from C. intybus and to explore main pharmacological actions of cichory a compound collection of C. intybus was built via consulting related references about chemical research on cichory.

Paracetamol was used as a model drug in this study to investigate the synergetic effects of lipid coating and beta-cyclodextrin (beta-CD) inclusion for masking the bitter taste of poorly soluble drugs. To control the concentration as low as possible of the free drug which produced a bitter taste, a kinetic model was established to calculate the drug distribution theoretically among the free drug in medium, lipid coated particles and molecular inclusion on the basis of the preparation and characterization of the lipid microspheres, so as to select the proper amount of beta-CD. Finally, the synergetic drug delivery systems were prepared and characterized by 1H nuclear magnetic resonance (1H NMR), molecular simulation and the electronic tongue. As a result, the drug release rate constant (k) of the lipid microspheres coated with octadecanol was determined as 0.001 270 s(-1). Then, the synergetic drug delivery systems were prepared with the ratio of 6.74 : 1 (w/w) for beta-CD and paracetamol. The chemical shift values for the fingerprint peaks of paracetamol all increased and hydrogen bonds were formed between the oxygen on the phenolic hydroxyl group, the nitrogen on the imino in paracetamol and the hydrogens on the hydroxyl groups in beta-CD. The results tested by the electronic tongue indicated that the paracetamol, lipid microspheres, beta-CD inclusion and their mixture showed different taste characteristics, with the bitterness order of the synergetic drug delivery systems approximately lipid microspheres < beta-CD inclusion < paracetamol, which confirmed the synergetic taste masking effects of lipid coating and beta-CD molecular inclusion. In summary, the synergetic taste masking was jointly achieved through the retard of the drug release by the lipid coating and the inclusion of the free paracetamol by beta-CD through hydrogen bonds.

OBJECTIVETo localize susceptibility loci in Chinese systemic lupus erythematosus (SLE) cohort by linkage disequilibrium mapping the genomic interval in human chromosome 16 so as to understand whether the pathogenesis of human SLE is related to chromosome 16.

METHODSFive microsatellite markers in chromosome 16 spanning from 57.79 cM to 65.1 cM were used for fluorescence based genotyping in 157 SLE families. Evidence for linkage disequilibrium was assessed using the extended transmission disequilibrium test (ETDT) program and Genehunter software. Susceptibility gene was searched in the positive locus, and real-time PCR method was used to detect gene expression.

RESULTSWith the ETDT, evidence for linkage disequilibrium of the marker D16S409 (P=0.0278) and D16S517 (P<0.0001) with SLE were found. It was observed that 271 bp allele of D16S517 was much in evidence for preferential transmission, while 277 bp allele was found to be transmitted less often than expected. Genehunter analysis is concordant with ETDT. By real-time PCR, OAZ(OLF1/ EBF-associated zinc finger protein) gene which is located in the positive locus showed higher expression in SLE patients than in normal controls.

CONCLUSIONResults reveal that 16q12 (58.46 cM) is associated with Chinese SLE. OAZ is a likely susceptibility gene in this locus for SLE.
