Objective　 To investigate the relationship between of serum bilirubin concentrations and risk of coronary heart drsease (CHD). Methods　 Serum bilirubin concentrations were determined in 12 cases with acute myocardial infarction(AMI)、37 cases with unstable angina pectoris (UAP) and 30 cases with UAP with arrhythmia. Results　 The serum total bilirubin(TB)、direct bilirubin(DB)、indirect bilirubin(IB) concentrations were lower in the three study groups of CHD than in the controls. There was significant difference between the patients with CHD and the controls. However, there was no significant difference among the three study groups of CHD. Conclusion　 Serum bilirubin concentrations was inversely and statistically significantly related to risk of CHD.

Objectives To culture and isolate Malassezia furfur which were suspected in sputum smears,and then to identify the isolates systematically.Methods From March 2010 to September 2011,133 lower respiratory tract secretion samples were collected in Beijing Hospital of the Ministry of Health which were suspected containing Malassezia furfur by Parker ink staining.The samples were inoculated and cultured on CHROMagar mediums containing 1％ Tween 60 ( which was modified from Candida chromogenic media) in the atmospheric environment at 35 ℃.The suspected colonies were selected and cultured on both SDA plates containing 0.5％ Tween 40 and SDA plates containing 0.5％ Tween 60.The traditional phenotypic identification methods were used to identify the pure colonies,including staining,growth on Sabouraud agar plates,Tween test,decomposing Escalin,Catalase test,Tween precipitation test and castor oil test.Then the suspected colonies were identified by analyzing the sequences of 18s rRNAs.Results The isolation rate of Malasseziafurfur from lower respiratory tract secretions was 47.4％ (63/133) and 63 strains were also identified as Malassezia furfur by traditional phenotypic identification methods combined with the 18s rRNA gene sequence analysis.Malassezia can be significantly distinguished from Candida by direct smear of the specimen with Parker ink staining.Conclusions Malassezia furfur was found as pink colonies on modified Candida chromogenic media which were significantly different from other Candida colonies.The isolation rate of lower respiratory tract secretions can be improved by modified Candida chromogenic media.The identification accuracy can be further improved by combining traditional phenotypic identification methods with 18s rRNA sequence analysis.

Objective To investigate the action of integron-mediated multidrug resistance in clinical multi-resistant Pseudomonas aeruginosa.Methods The strains of multi-resistant Pseudomonas aeruginosa were selected with K-B susceptibility method. The three-dimensional method was taken to differentiate the various beta-lactamases. The integron was determined by PCR with integron-specific primer. DNA sequencing was also used to analyze resistance-related gene in the integron in multi-resistant Pseudomonas aeruginosa.Results The positive rate of integron detection in multi-resistant Pseudomonas aeruginosa was 42.4%.Three kinds of different length integron were found .They were 750bp,1 000bp and 2 500bp and aadB,aadA2,aadB,aac6-II and PSE-1 were the resistance-related gene cassette in the integrons.Conclusions Integron took part in mutiple resistance in multi-resistant Pseudomonas aeruginosa.We should pay more attention to integron-mediated horizontal transference of mulidurg resistance to lessen the occurrence of multi-resistant strains.

Objective To discuss a new method of BMSCs culture which can reduce the lead-in of extraneous antigenic substances in the process of cell culture, and can thus better meet the demand on the quantity and biological characteristics of BMSCs in the clinical use of tissue engineering bone. Methods BMSCs from a human adult in vitro were induced by using autologous platelet-rich plasma instead of animal serum in high-carbohydrate DMEM (Dulbecco's minimum essential medium). After the cultured BMSCs were amplified rapidly by Rotary Cell Culture System, their growth status was observed and their biological characteristics were detected. Results The cells were in good growth status and presented fine biological characteristics. Their growth speed in Rotary Cell Culture System was observed to be evidently faster than that by conventional methods. Conclusions Rotary Cell Culture System by autologous platelet-rich plasma instead of animal serum is a good culture method to induce human BMSCs in vitro. The quantity and biological characteristics of BMSCs cultured in this way can meet the demand in clinical use.

OBJECTIVE:To provide reference for clinical rational use of anti-epileptic drugs. METHODS:In this retrospective review,serum concentrations of anti-epileptic drugs in a total of 499 patients who were treated with anti-epileptic drugs (such as sodium phenytoin,phenobarbital,carbamazepine and valproate sodium) in our hospital during 2007 were analyzed statistically. RESULTS:Among the patients receiving one kind of anti-epileptic drugs,206 cases (61.49%) were within normal range in blood concentration versus only 45 cases (44.12%) for patients receiving combined drugs. In addition,the above four drugs (sodium phenytoin,phenobarbital,carbamazepine and valproate sodium) were detected in 59.68% of the patients who took Chinese medicines,and among them,3.23% were within normal range in blood concentration. CONCLUSION:Monitoring on serum concentrations of anti-epileptic drugs is conducive to a better control of therapeutic concentration. It is advisable to refrain from using anti-epileptic drugs in combination but to adopt individualized administration. In addition,great importance should be attached to whether there are chemo-synthetic drug components contained in Chinese medicine.
