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.

Objective To study the clinicopathologic features and differential diagnosis of deep angiomyxoma(DAM). Methods Seven cases of DAM were collected from 2000 to 2008. All the patients were examined by microscopy and immunohistochemistry. Results 6 patients with DAM were females and 1 was male, with median age of 48.5 years. Median maximum dimension was 5.9cm, with invasive growth pattern. The tumor cells of DAM were infantile, spindle or stellate,diffuse and nodular arrangement. A distinctive histologic feature of DAM was its vascularity. Non-arborizing, thin-wall, ectastic capillaries or more commonly, small thick-wall vessels were dispersed throughout the tumor. Mast cells and extravasated red blood cells were frequently found in the stroma, immunohistochemical study showed that 7 cases were positive for vimentin, desmin, ER and PR, 5 for CD34 and SMA, and negative for S-100 and CK. Conclusion DAM is a rare soft tumor that occurs principally in the vulval and vagina region of woman. Misdiagnosis has happened frequently. Immunohistochemical staining are helpful to diagnosis for DAM, but no significance to distinguish it.

Electrocardiogram (ECG) signals are susceptible to be disturbed by 50 Hz power line interference (PLI) in the process of acquisition and conversion. This paper, therefore, proposes a novel PLI removal algorithm based on morphological component analysis (MCA) and ensemble empirical mode decomposition (EEMD). Firstly, according to the morphological differences in ECG waveform characteristics, the noisy ECG signal was decomposed into the mutated component, the smooth component and the residual component by MCA. Secondly, intrinsic mode functions (IMF) of PLI was filtered. The noise suppression rate (NSR) and the signal distortion ratio (SDR) were used to evaluate the effect of de-noising algorithm. Finally, the ECG signals were re-constructed. Based on the experimental comparison, it was concluded that the proposed algorithm had better filtering functions than the improved Levkov algorithm, because it could not only effectively filter the PLI, but also have smaller SDR value.

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.
