Objective To investigate the stimulate angiogenesis effect of bone marrow stem cell mobilization on coronary collateral development in the hearts of experimental myocardial infarction rats.Methods Left anterior descending coronary arteries were ligated to produce acute myocardial infarction(AMI)model in Wistar rats.Bone marrow stem cells were mobilized and home to the site of myocardial infarction by ginsenoside Rgl and Simvastatin.Hearts were harvested in the 24th hour,1st and 4th week after AMI modeling for histopathological examination.Immu nohistochemisty were used to detect infiltration of CD+34 cells and the expression of VⅢ factor in the part of ischemia.And infarct area were measured.Results Infarct area in mobilized group was obviously less than in AMI group.There were a great number of monocytes infiltrating with CD34 expression by immunohistochemisty in myocardial infracted zone in mobilized rats.Capillary density in mobilized group was greater than those of AMI and sham-operated groups.Conclusion In the AMI model of rat,bone marrow stem cells can be mobilized by ginsenoside Rgl and Simvastatin.The capillary density can be increased by mobilizing bone marrow stem cells.Ginsenoside Rgl and Simvastatin can improve the acute ischemic cardiac function by enhancing angiogenesis.

The quality of some earlier developed antibiotics is usually ensured by the combination of HPLC purity and microbiological potency measurement in the pharmacopoeias of various countries because the relationship between their purity and potency is not clearly quantified. Due to potency is assessed using certain units of measurement, it can not be directly traced to the international system of units (SI unit). This has become a hotspot in the study of the quantitative relationship between purity and potency of antibiotics. It would be quite an achievement to simultaneously determine both purity and potency using HPLC methods during quality control. This study evaluated a multicomponent antibiotic product, gentamycin, as a test sample. First, pure samples of the C components of gentamycin: C1a, C2, C2a and C1 were prepared, separately. Second, quantitative relationship (theoretical potency) between the purity and potency of each C component of gentamycin were determined using 1H NMR, HPLC-ELSD and microbiological assay method. One milligram of gentamycin C1a, C2, C2a and C1 was equal to 1 286.98, 1 095.74, 1 079.52 and 739.61 gentamycin units, respectively. Finally, a method for the determination of gentamycin potency was established based on the proportion and content of C components of gentamycin. The unification of purity and potency for gentamycin was achieved using only HPLC-ELSD. It is also demonstrated that C components of gentamycin and micronomicin produce the same responses under ELSD, which means that it is not necessary to prepare separate reference standards for each C component of gentamycin and that quantitative testing can be performed accurately using only one micronomicin reference standard. This study simplified the previous method for the determination of the content of C components of gentamycin using HPLC-ELSD. The developed method is suitable for regular use as a part of quality control and can simplify the rigmarole quality control procedures provided in current pharmacopeias.

Rheumatoid arthritis (RA) is an autoimmune disease, which is characterized by synovial inflammation. Hyperplasia sublining macrophages found in synovium is an early hallmark of RA and effective treatment results in their diminution. However, the origin of these sublining macrophages in synovium (including infiltrated macrophages and tissue-resident macrophages) are still unknown both in animal models of arthritis and RA patients, let alone the differences and feature of these macro?phages. In rheumatic synovium, macrophages are submitted to a large variety of micro-environmental signals which influence the phenotypic polarization and activation of macrophages. Understanding the mechanisms and functional consequences of the heterogeneous macrophages will contribute to confirm their potential role in synovial inflammation development. Furthermore, research on macrophage plasticity to soft-control their phenotypic polarization could lead to novel therapeutic approaches.

Objective:To analyze the job preference of doctors at township health center ( THC) and provide references for formulating effective policy. Methods:238 cases of doctors were sampled from Shandong, Anhui and Shaanxi provinces. Using a discrete choice experiment, we analyzed the data with a conditional logit model. Results:The most important job attribution was salary, followed by education for children, permanent post, work location, training opportunity, and years before promotion. The OR value of the monthly income of 8 000 yuan is 7. 0 compared to 2 000 yuan. Doctors will pay 3 857 yuan and 3 294 yuan respectively for better education for children and perma-nent posts. Monthly income increasing to 8 000 yuan will reduce the quitting rate from 35% to 8%, and providing better education for children and permanent posts will reduce 5%. The permanent posts at township health center and non-permanent posts in county hospital have the same appeal to the doctor. Conclusion:When choosing a job, doc-tors at THCs valued salary the most. Improving the education level for children can be beneficial for attracting and re-taining doctors at THCs. A permanent post is more attractive to doctors than non-permanent posts at THCs.

Emerging data indicated that HCV subverts the antiviral activity of interferon (IF); however,whether HCV core protein contributes to the process remains controversial. In the present study, we examined the effect of HCV core protein on interferon-induced antiviral gene expression and whether the effect is involved in the activation and negative regulation of the Jak/STAT signaling pathway. Our results showed that, following treatment with IFN-α, the transcription of PKR, MxA and 2'-5'OAS were down-regulated in HepG2 cells expressing the core protein. In the presence of HCV core protein,ISRE-dependent luciferase activity also decreased. Further study indicated that the core protein could inhibit the tyrosine phosphorylation of STAT1, whereas the level of STAT1 expression was unchanged.Accordingly, SOCS3, the negative regulator of the Jak/STAT pathway, was induced by HCV core protein. These results suggests that HCV core protein may interfere with the expression of some interferon-induced antiviral genes by inhibiting STAT1 phosphorylation and induction of SOCS3.

In this paper, actinomycetes were isolated from vermicompost by tablet coating method. Antimicrobial activities of actinomycetes were measured by the agar block method. Strains with high activity were identified based on morphology and biochemical characteristics, as well as 16S rDNA gene sequence analysis. The results showed that 26 strains of actinomycetes were isolated, 16 of them had antimicrobial activities to the test strains which accounts for 61.54% of all strains. Among the 16 strains, the strain QYF12 and QYF22 had higher antimicrobial activity to Micrococcus luteus, with a formed inhibition zone of 27 mm and 31 mm, respectively. While the strain QYF26 had higher antimicrobial activity to Bacillus subtilis, and the inhibition zone diameter was 21 mm. Based on the identification of strains with high activity, the strain QYF12 was identified as Streptomyces chartreusis, the strain QYF22 was S. ossamyceticus and the strain QYF26 was S. gancidicus. This study provided a theoretical basis for further separate antibacterial product used for biological control.
