Aim The effect of capsule bushenyanshou (BSYS), a compound of traditional Chinesemedicine, on the immunopharmacological activities of mice was investigated. MethodsThe indexes of immunopharmacological activity, such as the clearance rate of charcoalparticles, the lymphocyte transformation and the content of serum hemolysin, were mea-sured. Results Capsule BSYS (400, 800 mg?kg-1, qd ? 12) markedly increased theclearance rate of iv charcoal particles and 1he lymphocyte transformation stimulated invivo by PHA in mice. In hydrocortisone -treated mice(15 mg? kg-1, sc, qd ? 5), capsuleBSYS significantly enhanced the content of serum hemolysin and the weights of spleenand thymus. The results also demonstrated capsule BSYS performed a sighted inhibition ofthe delayed type hypersensitivity in mice. Conclusion Capsule BSYS has the capacity ofimmunological intensification and regulation.

HBV is a major health problem faced by human beings. The study of the mechanism of HBV infection has been a key point in this field. To carry out the related research on HBV, establishment of simple and available in vivo and in vitro infection models is the trend. Due to the close relationship between tree shrews and human/primates, the tree shrew model of HBV infection has attracted more and more attention. This review summarizes recent research, both at home and abroad, about in vivo and in vitro HBV infection in tree shrews, especially the research progress in in vitro culture of primary hepatocytes of tree shrews, and looks to the future research directions as well.

Objective To evaluate the accuracy and clinical application of endoscopic ultrasound guided fine needle aspiration (EUS-FNA) in diagnosis of occupying lesions in upper digestive tract and its pe-ripheral areas. Methods The data of 64 patients who underwent EUS-FNA for occupying lesions in upper di-gestive tract, between July 2006 and December 2007, were retrospectively analyzed. Results EUS-FNA was successfully performed on 62 patients, with a success rate of 96.88%. The overall diagnostic accuracy, sensi-tivity, specificity, positive predictive value and negative predictive value of EUS-FNA for occupying lesions in upper digestive tract and its peripheral areas were 88.71%, 86.54%, 100.00%, 100.00%, and 58.82%, respectively. There was no significant difference between the foei larger and smaller than 3cm (P > 0.05), re-garding the diagnostic accuracy and average puncture numbers. Diagnostic accuracy of those with real-time cy-tolngical evaluation was significantly higher than those without (P=0.029), and the puncture numbers were less (P=0.001). Among the total 99 punctures, the positive diagnostic accuracy of those with 5ml negative pressure suction was significantly higher than those of 10 ml (P = 0.044). Conclusion EUS-FNA is a safe and applicable approach to diagnosis of occupying lesions in upper digestive tract and its peripheral areas with higher diagnostic accuracy, sensitivity, specificity and positive predictive value. Moreover, the real-time cyto-logical evaluation and adequate negative pressure might facilitate the diagnosis accuracy.

Objective:To investigate the drug resistance of Yersinia pestis to 11 kinds of antibiotics in the natural foci of plague in Inner Mongolia Autonomous Region, and to provide a theoretical basis for scientifically and effectively selecting antibiotics for treatment of the plague. Methods:A total of 137 strains of Yersinia pestis isolated from the natural foci of plague in Inner Mongolia Autonomous Region at different times, regions, hosts and vectors were collected. According to Clinical and Laboratory Standard Institute (CLSI), the agar plate dilution method was used to determine the minimum inhibitory concentration (MIC) of the 11 kinds of antibiotics against 137 strains of Yersinia pestis, including ofloxacin, ciprofloxacin, kanamycin, streptomycin, ceftriaxone, ampicillin, chloramphenicol, spectinomycin, cefuroxime, tetracycline and sulfamethoxazole-trimethoprim. The MIC 50 and MIC 90 (the minimum concentration of drug which could inhibit 50% and 90% of bacterial growth) were calculated, and their sensitivity was determined according to CLSI standards. Results:Among 137 strains of Yersinia pestis tested, no strains of Yersinia pestis had single or multiple resistance to ofloxacin, ciprofloxacin, kanamycin, streptomycin, ceftriaxone, ampicillin, chloramphenicol, spectinomycin, cefuroxime, tetracycline and sulfamethoxazole-trimethoprim. According to CLSI standards, 137 strains of Yersinia pestis were all sensitive to the 11 kinds of antibiotics; among them, ofloxacin, ciprofloxacin, ceftriaxone and sulfamethoxazole-trimethoprim had higher antibacterial activity, with MIC 90 < 0.250 μg/ ml; the antibacterial activity of spectinomycin was the lowest, with MIC 90 of 16.000 μg/ml. Conclusions:The Yersinia pestis isolated from the natural foci of plague in Inner Mongolia Autonomous Region is not found to have single or multiple resistance to the 11 kinds of antibiotics. Continuous drug resistance monitoring of Yersinia pestis should be carried out to provide a basis for clinical medication.

This study was designed to evaluate the effects of drilling through the growth plate and using adipose-derived stem cells (ADSCs) and bone morphogenetic protein-2 (BMP-2) to treat femoral head epiphyseal ischemic necrosis,which can be done in juvenile rabbits.Passage-four bromodeoxyuridine (BrdU)-labeled ADSCs were cultured,assayed with MTT to determine their viability and stained with alizarin red dye to determine their osteogenic ability.Two-month-old,healthy male rabbits (1.2 to 1.4 kg,n=45) underwent ischemic induction and were randomly divided into five groups (group A:animal model control;group B:drilling;group C:drilling & ADSCs;group D:drilling & BMP-2;and group E:drilling & ADSCs & BMP-2).Magnetic resonance imaging (MRI),X-ray imaging,hematoxylin and eosin staining and BrdU immunofluorescence detection were applied 4,6 and 10 weeks after treatment.Approximately 90％ of the ADSCs were labeled with BrdU and showed good viability and osteogenic ability.Similar results were observed in the rabbits in groups C and E at weeks 6 and 10.The animals of groups C and E demonstrated normal hip structure and improved femoral epiphyseal quotients and trabecular areas compared with those of the groups A and B (P＜0.01).Group D demonstrated improved femoral epiphyseal quotients and trabecular areas compared with those of groups A and B (P＜0.05).In summary,drilling through the growth plate combined with ADSC and BMP-2 treatments induced new bone formation and protected the femoral head epiphysis from collapsing in a juvenile rabbit model of femoral head epiphyseal ischemic necrosis.

To clone and analyze a member of the Auxin/indole-3-acetic acid (Aux/IAA) gene family, RgIAA1, from Rehmannia glutinosa. The transcriptional EST database of R. glutinosa was used to clone the new Aux/IAA gene by cDNA probe of AtIAA14. Bioinformatics was applied to analyze the sequence characteristics of RgIAA1 protein and construct phylogenetiC trees. Quantitative RT-PCR has been applied to detect the transcription level of RgIAA1 in seven tissues as well as in leaves under three stresses. The results showed that, the cDNA sequence of RgIAA1 contains 903 bp was obtained. The open reading frame (ORF) of RgIAA1 was 681 bp encoding 226 amino acids, which has typical structural domains and characteristic sequence of Aux/IAA family proteins. RgIAA1 showed the highest expression level in unfolded leaf, followed by the stem. And the expression of RglAA1 was quickly decreased with leaf growing up. The transcription level increased under continuous cropping conditions while it reduced both in salinity and waterlogging stresses. RgIAA1, an Aux/IAA gene from R. glutinosa has been obtained for the first time, which can lay the foundation for further studies about its molecular function in development and responses to stress.
