Objective To survey and analyze the situation of nurses about music therapy. Methods A questionnaire survey was used to investigate 250 nurses. Results In addition tO the cognition of the major role of music therapy(P>0.05),for nurses with the undergraduate and higher level qualifications, there were significant differences in its meaning, the main mechanism, the main style, the requirements of environment and perpetrators. The choice of music types, aesthetic fatigue from music, the patient's quality requirements, and other aspects of cognition compared to the nurses with a degree low than a bachelor degree(P<0.05).Main source of knowledge Was from the media channels.46.1 percent of the nurses didn't Use music therapy.31.4 percent of the nurses rarely used it. Conclusions Nurses with different qualifications have different awareness of music therapy. The professional music therapy of nurses should be raised. The source of music knowledge should be increased, at the sanle time music therapy should be intensified in the nursing work.

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.

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.

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. The three-dimensional crystal structure of xanthine oxidase (PDB code: 1N5X) from Protein Data Bank was downloaded.. Autodock 4.2 was employed to screen the inhibitors of xanthine oxidase from cichory 70 compounds were found to possess quite low binding free energy comparing with TEI (febuxostat). C. intybus contains constituents possessing potential inhibitive activity against xanthine oxidase. It can explain the main pharmacological actions of cichory which can significantly lower the level of serum uric acid.

Hemiplegics after stroke are often disabled in sit-to-stand(STS).This article discussed the biomechanics of STS in the hemiplegic stroke patients,in terms of kinematics,kinetics and surface electromyography,and the rehabilitation for the stroke patients with STS dysfunction.It was found that the stability,duration,symmetry of support and degree and se-quence of muscular activation were different when the patients finished the STS task in three foot positions of natural, symmetrical and unaffected foot behind.The early STS rehabilitation training or other rehabilitation may improve the function of the hemiplegic lower extremity to prevent falls and apraxia.

BACKGROUNDPrevious studies have suggested that interrupted clearance of nuclear DNA-protein complexes after cell death might initiate and propagate systemic lupus erythematosus (SLE). Deoxyribonuclease I (DNaseI) may be responsible for the removal of DNA from nuclear antigens at sites of high cell turnover, thus preventing the onset of SLE. The purpose of this study was to genotype the single nucleotide polymorphisms (SNPs) of DNase1 and characterize its gene expression and alternatively spliced transcripts in Chinese patients with SLE in order to understand the pathogenic role of DNase1 in human SLE.

METHODSFour SNPs located at the 3' end of the DNase1 gene, as listed on the SNP website, were selected for analysis. Those SNPs with relatively high heterozygosity were chosen for genotyping in 312 Chinese SLE families using the Taqman minor groove binder (MGB) allelic discrimination method. Haplotypes were constructed and linkage disequilibrium tests were performed using GeneHunter. DNase1 mRNA expression was detected using real-time polymerase chain reaction (PCR), and alternatively spliced transcripts were isolated using capillary electrophoresis. Any effects the specific SNP haplotypes had on DNase1 gene expression and the alternatively spliced transcripts were also assessed.

RESULTSrs179982 and rs1053874 had high heterozygosity, about 0.5 in this Chinese cohort, while rs1059857 was also found to be heterozygous. Analysis of the haplotype combining rs179982-rs1030874 (C-G) and rs179982-rs1030874-rs1059857 (C-G-G) revealed a skewed transmission in favor of affected offspring. DNase1 gene expression was higher in SLE patients than in normal controls (P < 0.001), but this was not related to disease activity or SNP haplotype. Capillary electrophoresis revealed that the pattern of alternatively spliced transcripts in patients differed from that of normal controls. Furthermore, different SNP haplotype combinations generated different transcript patterns in SLE patients.

CONCLUSIONSThe SNP haplotypes are in linkage disequilibrium in Chinese SLE patients and may induce the disease through a modification of DNase1 mRNA splicing rather than at the level of mRNA expression. There is a relatively unique transcript band in SLE patients independent of special haplotype, which suggests that other unknown factors might be involved in adjusting gene expression.

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.

OBJECTIVETo detect the effect of Nocardia rubra cell wall skeleton (Nr-CWS) on tumorigenicity induced by TC-1 cells and to clinically study anti-human papillomavirus effect of Nr-CWS in lower genital tract of women.

METHODSTumor model was established by injecting TC-1 cells subcutaneously in SCID mice, then divided them into 3 groups randomly and injected with isovolumetric physiological saline, 60 micrograms/ml Nr-CWS and 120 micrograms/ml Nr-CWS respectively, the growth of tumors was measured one week later. Nr-CWS was applied on 45 HPV positive women whose TCT test was normal and without cervical erosion 2-3 days after menstruation. HPV was detected again 3 months later to explore the effect of Nr-CWS on HPV infection in female lower genital tract.

RESULTSThe animal experiment showed the weight of transplanted tumors in treated group was less than that of control group (chi2=12.5, P= 0.002). The tumor inhibition rate was 59.1 percent and 84.2 percent in the groups treated with Nr-CWS 60 and 120 micrograms/ml Nr-CWS; the results of HPV detection in 23 out of the 45 cases (51.1 percent) became negative after the 3-month treatment; the viral load was reduced in 9, and there was no change in viral load in 13 cases. Significant difference was found between the rates of undetectable viral load and the natural viral disappearance rate (P less than 0.05).

CONCLUSIONNr-CWS has an inhibitory effect to TC-1 cell tumorigenesis and clinical application of Nr-CWS may eliminate the HPV infection in lower genital tract of a considerable proportion of women with HPV infection.
