A myxobacterial strain, So ce cpu-1, was isolated from a soil sample near the Huanghai beach. So ce cpu-1 had broad antimicrobial activity, active component has maxima] absorption at 210 nm. The effects of different culture conditions on the yield of the secondary metabolites were investigated. The results showed that, when cultivating the strain in the M, medium (containing 10% w/v D312 neutral absorber resin ), the air up to 70% of the whole flask volume, adding 5?L the secondary metabolites as the revulsant, at 30℃, 200r/min, for 6 days, the yield of the secondary metabolites achieved the maximum.

Objective To explore expression of nuclear factor kappa B (NF-κB) and change of peripheral blood dendritic cells(DCs) surface. Methods The expression of NF-κB and DCs in kidney of 40 LN cases were measured,by ALP-anti-ALP mice immune complex law(APAAP) and density gradient separation centrifugal meth-ods. Results kidney tissue of LN patients, NF-κB in the glomeruli and tubules showed a high level of expression ; CD80+ ,CD86+, HLA-DR+ expression decreasedtacrolimus group than the control group Division before and after the shape of the DCs had no effect on tacrolimus after the DCs could inhibit the proliferation of T cells and T cells to Th2 cell transformation. Conclusinn In vitro Tacrolimus inhibits the DCs mature in LN patients, NF-κB in LN kidney LN local expression and the occurrence and development of related.

OBJECTIVE To investigate the use of antibiotics in our Outpatient Department during 2006-2007,and to analyze and evaluate the trend and rationality.METHODS The data about consumption quantity and consumption sum of antibiotics in our Outpatient Department during 2006-2007 were retrieved by means of computer management software in the department of pharmacy for the analysis of the clinical use of antibiotics using the method of defined daily dose(DDD).RESULTS Fluoro quinolones,cephalosporins and plant antibiotics have dominated the first places among the antibiotics used in our hospital,and the consumption of cephalosporins kept increasing year by year.CONCLUSIONS The use of antibiotics in our hospital should be further standardized to ensure the drug using safe,efficient and economic in our hospital.

OBJECTIVE To promote clinical rational use of antibiotic prophylaxis through surveying it in Obstetrics and Gynecology Department (OG) by pharmacists. METHODS Data of 223 cases using of antibiotic prophylaxis in OG were retrospectively analyzed. According to unreasonable use of antibiotic prophylaxis,the clinical pharmacists put out reasonable measures and directed treatment in succedent 206 patients. RESULTS The rate of unreasonable use of antibiotic prophylaxis in 223 cases was 100% and rate of infection after operation was 9.87%. After giving intervention,the rate of unreasonable use of antibiotic prophylaxis and infection were reduced to 3.88% and 1.46%,respectively (P

BACKGROUND:Autologous bone marrow aspirate concentrate is often applied in patients from Department of Orthopedics and those with severe limb ischemia, but rarely applied in Department of Oral and Maxil ofacial Surgery, especial y in Department of Oral Implantology. The effect of autologous bone marrow aspirate concentrate on promoting peri-implant bone regeneration deserves further studies.
OBJECTIVE:To evaluate the effect of bone marrow aspirate concentrate in the repair of peri-implant bone defect.
METHODS:Bone marrow 5 mL was extracted from posterior superior iliac spine of experimental dogs and bone marrow cel s were counted before and after concentration. Bone defect (4 mm × 4 mm × 4 mm) was prepared in the middle of bilateral mandibular premolar, which was randomly implanted with gelatin sponge plus bone marrow aspirate concentrate, autologous bone and gelatin sponge. At 4 and 12 weeks after surgery, bone defect specimens were histological y observed. The new bone formation rate and new bone mineral density were calculated.
RESULTS AND CONCLUSION:After centrifugation, the concentrations of nucleated cel s in bone marrow aspirate concentrate were increased by (2.78±0.22) times. More colony-forming units were found after cel culture. Histological analysis showed that, significantly higher new bone formation rate and new bone mineral density occurred in gelatin sponge plus bone marrow aspirate concentrate group, compared with autologous bone group and gelatin sponge group at 4 weeks (P<0.05). The new bone formation rate in gelatin sponge plus bone marrow aspirate concentrate group was significantly lower than that of autologous bone group, and higher than that of gelatin sponge group at 12 weeks (P<0.05). However, the difference of new bone mineral density in the three groups was not significant (P>0.05). Autologous bone marrow aspirate concentrate can significantly improve new bone mineral density and quantity in the pre-implant bone defect.

To study the metabolite excretion of theophylline, a rapid and specific method by liquid chromatography with heated electrospray ionization tandem mass spectrometry (LC-HESI/MS/MS) method for simultaneous determination of theophylline, 1, 3-dimethyluric acid (1,3-DMU), 3-methylxanthine (3-MX) and 1-methyluric acid (1-MU) in human urine was developed using theophylline-d6 and 5-fluorouracil as internal standards. Selected reaction monitoring (SRM) with heated electrospray ionization (HESI) was used in the negative mode for mass spectrometric detection. After diluted with methanol and centrifuged, the analytes and ISs were separated on a XDB-Phenyl (150 mm x 4.6 mm, 5 microm) column with a mixture of water-methanol-formic acid (30 : 70 : 0.15) as mobile phase at a flow rate of 0.6 mL x min(-1). The linear calibration curves for theophylline, 1, 3-DMU, 3-MX and 1-MU were obtained in the concentration range of 1.0-250 microg x mL(-1), separately. The method herein described is effective and convenient, and can be used for determination of theophylline and its three metabolites. The results showed that urinary excretion ratio of theophylline, 1,3-DMU, 3-MX and 1-MU is approximately 1 : 3 : 1 : 2 in Chinese subjects, which is similar to the reported excretion pattern in Caucasian.
