Bacillus anthracis collagen-like protein(BclA) is a structural component of the exosporium filaments,as well as the immunodominant antigen on the spore surface.The genes encoding BclA proteins were cloned and sequenced from three Bacillus anthracis strains separated from China.It was founded that the BclA proteins of strain A16R and 40048,containing 388 and 322 amino acids,72 and 50 copies of GXX repeat,5 and 3 copies of 21-amino-acid sequence(GPT)_(5)GDTGTT(BclA repeat) respectively,are different from those reported by foreign scholars;while the BclA protein of strain 40022,containing 370 amino acids,66 copies of GXX repeat,and 5 copies of BclA repeat,is identical with that of strain 53169 reported by others.The results are helpful for the molecular typing of B.anthracis strains,and provide a basis for the elucidation of the pathogenesis and immunogenicity of B.anthracis spore.

ObjectiveTo investigate the impact of metal plate on radiation dose distribution by Monte Carlo (MC) code. MethodsThe metal plates with 0. 4 thick were placed in water at 5 cm, all the plate irradiated with 6 MV X-ray were simulated by MC code, SSD =100 cm. The percentage depth dose with or without metal implants were compared. ResultsThe surface absorbed doses on incident plane of stainless steel plate and titanium plate were increased by 19. 6% and 15.7% respectively as compared water,the dose influence was less than 1.5% more than 0. 3 cm outside the incidence plane. The doses on the exit surface of stainless steel plate and titanium plate were lowered by 8. 6% and 8. 2% when compared with water, the dose impacts of this places where were from the exit surface of stainless steel plate 、titanium plate more than 1.2 cm,0. 9 cm were less than 1.5%. The surface absorbed doses on incident plane of stainless steel plate were increased by 3.9% respectively as titanium plate, the dose of the exit surface of stainless steel plate and titanium plate was similar. Conclusions MC method is a fast and accurate calculation method. The influence of metal plate on the radiotherapy dose distribution is significant. Under the such condition, the impact of stainless steel plate is much more than that of titanium alloy plate.

Ambroxol and clenbuterol were extracted from human plasma samples by liquid-liquid extraction, ambroxol was separated on a Zorbax XDB-C18 column and detected by tandem mass spectrometry with an atmospheric pressure chemical ionization interface after oral administration of a compound preparation. Clenbuterol was separated on a Zorbax XDB-C8 column and detected by tandem mass spectrometry with an electrospray ionization interface. Diphenhydramine is used as the internal standard. The linear concentration ranges of the calibration curves for ambroxol and clenbuterol were 0.080 - 400 microg x L(-1) and 5.0 - 5 000 ng x L(-1), respectively. The lower limits of quantification were 0.080 microg x L(-1) for ambroxol and 5.0 ng x L(-1) for clenbuterol, individually. The inter-day and intra-day precision (RSD) across three validation run over the entire concentration range was below 7.5%, and the accuracy (RE) was within +/- 2.5% for both ambroxol and clenbuterol. The methods were used to determine the pharmacokinetic parameters of ambroxol and clenbuterol in human plasma after oral administration of a compound preparation containing 60 mg ambroxol hydrochloride and 40 microg clenbuterol hydrochloride. The method was proved to be highly sensitive, selective and suitable for the pharmacokinetic study of different compound preparations containing ambroxol and clenbuterol.

The aim of this study was to investigate the protective effect of exogenous bcl-2 on spinal cord motoneurons following sciatic nerve axotomy. After epineurium suturing, sense bcl-2 (Ad/s-bcl-2), antisense bcl-2 (Ad/as-bcl-2), or reporter gene lacZ (Ad/lacZ) recombinant adenovirus or NS was injected into the sciatic nerve 0.5 cm distant from the sutured point respectively in different groups. The rats were transcardially perfused with 4% paraformaldehyde on postoperative 48 h, 7 d, 15 d and 30 d respectively and the spinal cords of L4 to L6 were harvested. X-gal staining, bcl-2 in situ hybridization and immunohistochemical staining, TUNEL (terminal deoxynucleotidyl transferase mediated dUTP nick end labeling) staining and AChE (acetyl cholinesterase) histochemical staining were used. We observed that the exogenous lacZ gene was expressed in the spinal cord of Ad/lacZ group, and sense bcl-2 significantly decreased the number of apoptotic motoneurons and the decreasing degree of AChE activity of the motoneurons in the spinal cord induced by sciatic nerve axotomy and accelerate AChE activity recovery. However, antisense bcl-2 increased the number of apoptotic motoneurons and the decreasing degree of AChE activity of the motoneurons in the spinal cord induced by sciatic nerve axotomy and prolonged AChE activity recovery. These results demonstrate that exogenous bcl-2 may protect motor neurons from injury induced by peripheral nerve axotomy.
