Objective To investigate the effectiveness of background music in operating room on psychology of patients and medical personnels. Methods A total of 127 patients who would receive selective operation and 65 surgical staff in our hospital were randomly divided into the intervention group and the control group. There were 63 patients and 30 medical personnel in the intervention group, 64 patients and 35 medical personnel in the control group. Routine care was given to all patients, and background music was broadcasted after patients and medical personnels coming into operating room in the intervention group. The blood pressure and heart rate of patients were contrasted, and the anxiety status was evaluated by Self-Rating Anxiety Scales (SAS), Visual Analogue Scale was used to appraise the horror, discomfort and pain between the control group and the intervention group. Results Diastolic pressure and systolic pressure was higher and heart rate was more rapid in the control group than in the intervention group. SAS score of patients and medical personnel was higher in the control group than in the intervention groups, degree of horror, pain and complaint in patients was more apparent in the control group than in the intervention group. Conclusions Background music could release negative emotion and was helpful for stabling the mood of medical personnel and preserving physical and mental health of patients.

Objective:To explore the diagnostic value of color Doppler echocardiography for cardiac tumors .Meth-ods:Clinical data of 87 patients with cardiac tumors were retrospectively analyzed ,including their diseased loca-tion ,clinical manif′estations and echocardiography feature .Results:All cardiac tumors obtain pathologic confirma-tion .There were 73 patients (83.9% ) with benign cardiac tumors ,including 66 patients (90.4% ) with myxoma and seven patients with other types ;there were 14 patients (16.1% ) with malignant cardiac tumors .Echocardiography indicated that myxoma was often located in left atrium (n=58) ,most cases possessed pedicell,its activity was large ;Other type benign cardiac tumors feature :The 6 case (86% ) were generated inside cardiac muscle without pedicell, its echo was more strong ;malignant tumors:its attachment surface was wide without pedicell,and it may show with globular or cauliflower ,and accompanied hydropericardium mostly .Conclusion:Echocardiography can dynamically observe the form ,size ,echo and hemodynamic changes of tumors ,its diagnostic accuracy is high .Myxoma is most frequent cardiac tumor .

Heparinases,a kind of polysaccharide lyases,can degrade heparin and heparin sulfate to low molecular weight polysaccharides.It has been noted that many bacteria have heparinases although only few of them have been purified and characterized.Heparinases I,II and III from Flavobacterium heparinum have been extensively studied for many years and been commercialized recently.Heparinases have some important applications in the industry and clinic as well as in the determination of heparin structure,which is a very important anticoagulant drug used world-widely.The recent progresses in isolation of heparinase-producing bacteria,genome mapping of heparinase homologs in sequenced bacteria and archaea genomes,purification of heparinases and the study of their biochemistry and regulation were reviewed.The recombinant expression of these enzymes as well as important applications of heparinases and their potential applications in the future will also be highlighted.

ObjectiveTo explore the relative factors of the compliance in schizophrenic out-patients.Methods118 schizophrenic out-patients chosen randomly were investigate with the compliance and assessed with Clinical Global Impression-Severity of Illness (CGI-SI), Social Disability Screening Schedule (SDSS), Brief Psychiatric Rating Scale (BPRS) and Treatment Emergent Symptom Scale (TESS) by telephone. Logistic regression analysis was used to confirm the relative factors of the compliance.Results56.8% of all patients were of full compliance. The risk factors of compliance in schizophrenic out-patients were the frequency of medicine taken, the scores of CGI-SI and the insight of the illness. ConclusionIt is important to choose effective and convenient antipsychotic drugs and improve the insight of the illness to enhance the compliance of the schizophrenic out-patients.

Objcetives To sparch for the change of cerebrospinal fluid ferritin (CSF-Ft) content and its clinical significance.Methods The 42 patients with acute lymphatic leukemia(ALL)diagnosed by bone marrow biopsy were divided into 3 groups. There were 14 cases in Ⅰ group [introduced therapy stage without central nervous system leukemia(CNSL)7, 24 cases in Ⅱgroup (complete remission stage without CNSL) and 18 cases in Ⅲ grotip (with CNSL). There were 17 patients with viral encephalitis in viral encephalitis group and 15 patients without central nervous system oisease in control group. The CSF-Ft and SFt were determined by radioimmunoassay.Results The CSF-Ft contents of Ⅰ、Ⅱ、Ⅲ 、viral encepbalitis and control groups are 7.03 ?2.21 ?g/L,6.75 ?1.94?g/L, 31.06 ? 8.85?g/L, 7.26?1.83?g/L and 6.52 ?1.57?g/L. The CSF-Ft content in Ⅲ group are bigher than that in the other group (P

Several kinds of column chromatography method were used to investigate the chemical constituents of the leaves of Lophatherum gracile. The structures of the isolated compounds were identified based on their physicochemical properties and spectral data. A new flavone C-glycoside was isolated and its structure was identified as 3'-methoxyl-luteolin 6-C-beta-D-galactopyranosiduronic acid (1 --> 2) -alpha-L-arabinopyranoside (1).

SARS-CoV is a newly discovery pathogen causing severe acute respiratory problems.It has been established that the S protein in this pathogen plays an important rule in the adsorption and penetration of SARS-CoV into the host cell by interaction with the ACE2 receptor.To determinant which functional motif of the S protein was involved in the interaction with ACE2,seven truncated S proteins deleted from the N or C terminal were obtained by an E.coli expression system and purified by column chromatography to homogeneity.Each truncated S protein was fixed on to the well of an ELISA plate and an interaction was initiated with the ACE2 protein.The adsorption were quantified by ELISA,and the results indicated that amino acids from 388 to 496 of the S protein was responsible for the interaction with the ACE2 receptor,and the interaction could be completely disrupted by an antibody specific to these amino acids.Deletions adjacent to this domain did not appear to have a significant impact on the interaction with ACE2,suggesting that the S protein of SARS-CoV could be developed as a vaccine to prevent the spread of SARS-CoV.
