BACKGROUND:The poly(hydroxybutyrate-co-hydroxyoctanoate) osteochondral scaffold which has been constructed in previous experiments has good biocompatibility and biodegradability and generates non-toxic degradation products.
OBJECTIVE:To observe the vascularization of rabbit renal microvascular endothelial cels co-cultured with poly(hydroxybutyrate-co-hydroxyoctanoate) osteochondral scaffold.
METHODS:The poly(hydroxybutyrate-co-hydroxyoctanoate) osteochondral scaffold having a three-layer structure (layer of bone/bone and cartilage interface layer/layer of cartilage) was prepared by solvent casting/particle leaching method. The renal microvascular endothelial cels at passage 3 were seeded onto the scaffold of bone layer. The proliferation of the renal microvascular endothelial cels growing on the scaffolds was examined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method, the growth of cels in the scaffold was observed by hematoxylin-eosin staining under electron microscope after 10 days.
RESULTS AND CONCLUSION:The integrated osteochondral scaffold had a clear appearance of three-layer structure, which had closed connections between the three layers. Porous bone layer was visible as wel as uniform and interlinked pores, and the porosity was 78%. The renal microvascular endothelial cels seeded onto the scaffold proliferated wel and presented a three-dimensional growth after 10 days of co-culture, but there were no cels on the interface layer. Cels which adhered and grew between the pores of the bone layer were observed through hematoxylin-eosin staining. Cels showed a luminal-like structure growing on the scaffold with the porous structure, but they did not grow into the interface layer of bone and cartilage.

Background:Chronic atrophic gastritis(CAG)is a kind of chronic gastritis with atrophic changes of gastric mucosa. The studies on peripheral blood biomarkers in CAG are rare. Aims:To investigate the methylation of peripheral blood CpG sites in Runx3 gene promoter region in CAG patients. Methods:Eighty-two mild CAG patients,73 moderate to severe CAG patients from June 2013 to May 2014 at Daqing Oilfield General Hospital were enrolled,and 45 patients with normal gastric mucosa were served as controls. The methylation of CpG sites in Runx3 gene promoter region was measured by MALDI-TOF-MS. mRNA expression of Runx3 was determined by fluorescent quantitative PCR,and the protein expression of Runx3 was determined by Western blotting. Results:Compared with the control group and mild CAG group,methylation levels of CpG13,CpG14 and CpG15 sites in Runx3 gene promoter region were significantly increased in moderate to severe CAG group(P < 0. 05),the mRNA and protein expressions of Runx3 were significantly decreased( P < 0. 05). No significant differences in methylation of CpG sites in Runx3 gene promoter region and mRNA and protein expressions of Runx3 were found between mild CAG group and control group( P >0. 05 ). Conclusions:The hypermethylation of peripheral blood CpG13,CpG14 and CpG15 sites in Runx3 gene promoter region can inhibit the expression of Runx3 in CAG patients,and can be used potentially as the biomarker for clinical staging of CAG.

This article was aimed to study the chemical constituents in groups of effective components extracted from Xiaoxuming Decoction. Twelve compounds were isolated and purified by dynamic axial compression column chromatography. Their chemical structures were identified by spectral analysis. The results showed that twelve compounds were isolated and identified as octacosanoic acid(1), cetanol(2), oroxylin A(3), wogonin(4), baicalein(5), tetrandrine(6), fangchinoline(7), wogonoside(8), baicalin(9), paeoniflorin(10), amygdalin(11), manntol(12). It was concluded that all compounds were isolated from this compound prescription for the first time.

Currently, bacterial resistance situation in health care settings is very serious in China, and the prevalence of a variety of common multidrug-resistant bacteria and pan-resistant bacteria are relatively high. Drug-resistant bacteria in Gram-positive bacteria are mainly methicillin resistant Staphylococcus aureus ( MRSA ) and macrolide-resistant Streptococcus, while glycopeptide-resistant enterococci are still at a low level.The clonal distribution of MRSA and mechanisms of Streptococcus resistance in China are different from those in European and American countries.Cephalosporins and quinolones resistance are the marked characteristic of Enterobacteriaceae with a high occurrence over 60%. Carbapenem-resistant Klebsiella pneumoniae shows a rapid upward trend, and producing KPC-2 type carbapenemases is the main mechanism of its resistance.Resistance in Pseudomonas aeruginosa is relatively stable, with resistant rates ranging from 20%to 30%.Multi-drug resistant Acinetobacter baumannii is a big problem in clinic.More than 50% Acinetobacter baumannii strains are resistant to carbapenems and cephalosporins, and tigecycline-resistant Acinetobacter baumannii is increasing.This paper systematically reviews the status and characteristics of bacterial resistance in last five years with referring to the surveillance data of antimicrobial resistance and the findings of related mechanisms.
