The development of clinical microbiology laboratory is an essential part in promoting the development of clinical microbiology and the basis rational use of antimicrobial agents.Under the circumstances of national specific rectification of antimicrobials,clinical microbiology laboratory should focus on self-buildup and improvement.The development of clinical microbiology laboratory should focus on development of both software and hardware capabilities for lab examination and diagnosis in an all-round way,enhance the antimicrobial susceptibility surveillance,and emphasize and communication and cooperation between laboratory and other departments e.g.clinical departments,pharmacy department and nosocomial surveillance and control office,making concept translation from past ‘paramedical department' to a ‘platform department',contribute its due share to the rational uses of antimicrobial agents.

Small intestinal submucosa has been applied in a variety of areas of basic and clinical study with its Characteristics of anti-infective and Low immunogenicity and so on.However,it is common to find the shrinkage and other problems in some tissue repair,and affects the functional recovery of repaired tissue to a certain extent.Thus,it is still a question to be resolved that how to avoid the shrinkage and other adverse effects after tissue repair.This paper provides a reliable basis for further correct understanding of the SIS's capacity of tissue repair by reviewing and summarying its characteristics and present situation of tissue repair,especially put forwarding the shrinkage problem.

Magnetic resonance imaging (MRI)has apparent dominance in nasopharyngeal carcinoma (NPC) diagnosis,staging,the plan of radiotherapy target and assessment of efficacy because of its high-contrast of parenchyma and muli-parameters imaging.Especially diffusion-weighted imaging (DWI) developed in several years,it can provide qualitative and quantitative information at the cellular level about tumor cellularity and the integrity of cell membranes,which is valuable for tumor detection,cervical lymph nodes metastases,systemic transfer,monitoring and predicting the treatment response of nasopharyngeal carcinoma.

AIM: To investigate the relationship between Alzheimer disease(AD) and alpha 2-macroglobulin(α2M) initially so as to provide evidence for the pathogenesis of late-onset AD.METHODS: The significance of α2M in the late-onset AD was revealed through pathology of α2M in AD and the polymorphism of α2M in AD patients.RESULTS: The association between AD and α2M region on the twelfth chromatosome was analyzed with the genic linkage, and pathological symptom of α2M in AD patients was supported by many evidences. Two polymorphism sites of α2M were located on the 12P12-13, which could increase more risks to AD patients.CONCLUSION: It is significant to investigate the frequency, mutation,polymorphism and expression of gene α2M for the pathogenesis of late-onset AD and its genic diagnosis.

Objective To translate the English version of Diabetes Continuity of Care Scale (DCCS) into Chinese and to test the reliability and validity of the Chinese version of DCCS in diabetes mellitus patients.Methods Totally 245 patients with diabetes mellitus were recruited and were investigated by the Chinese version of DCCS.Results The internal consistency coefficient of the Chinese version of DCCS ranged from 0.728 to 0.942,which was ＞0.70;split half coefficient r=0.784,and the test-retest was 0.864 while which of each dimension ranged from 0.785 to 0.886.The content validity index was 0.934.Factor analysis got five factors,which explained 76.574％ of the total variance;the factor loading of each item was ＞0.4.Conclusions The Chinese version of DCCS has been proved to be reliable and valid.It can be used as a valid tool for the measurement of continuity of care in patients with diabetes mellitus.

Objective To investigate the changes and significance of serum N-terminal pro-brain natriuretic peptide ( NT-proBNP) levels in mice model with viral myocarditis( VMC) . Methods 100 Balb/c mice were randomly di-vided into VMC group ( n=60 ) and control group ( n=40 ) . Mice in VMC group were injected intraperitoneally coxsackievirus B3 ( CVB3 ) , while mice in control group were treated with the same amount of virus-free DMEM cul-tivate liquid. 10 mice of each group were sacrificed on 3, 7, 14, and 28th day after VMC modeling and their blood and heart tissues were collected. The serum NT-proBNP levels in two groups of mice were detected by ELISA. Pathological changes in myocardial tissue were examined with hematoxylin and eosin stain. The relationship be-tween serum NT-proBNP concentration and cardiac pathology score of VMC group at different time points were ana-lyzed. Results The serum NT-proBNP levels of VMC group were significantly higher than that of control group( P<0. 05 ) . There was a significant statistical difference between NT-proBNP levels of VMC group at different time points( P <0. 05 ) . The NT-proBNP level was positively correlated with myocardial histopathology scores ( r =0. 829 , P<0. 05 ) . Conclusion Serum NT-proBNP levels may reflect severity of myocardial injury in mice with VMC. NT-proBNP can be used as one of serum indicators to judge the risk stratification in mice with VMC.

BACKGROUND:Bio-Gide col agen membranes show a good biocompatibility with stem cells. But the research on the osteogenetic differentiation of bone marrow mesenchymal stem cells cultured on the Bio-Gide col agen membranes is rarely reported. OBJECTIVE:To observe the effect of Bio-Gide col agen membranes on the proliferation and the osteogenetic differentiation of bone marrow mesenchymal stem cells. METHODS:Bone marrow mesenchymal stem cells from rabbits were isolated and cultured by using the whole bone marrow adherence method in vitro. Passage 3 bone marrow mesenchymal stem cells were selected and seeded on the Bio-Gide col agen membrane pretreated petri dish (experimental group) and simple petri dish (control group). The proliferation of bone marrow mesenchymal stem cells was detected by cellCounting Kit-8 at 1, 4, 7, 14 days. The supernatant of the cells cultured in osteogenic differentiation medium were col ected to detect the activity of alkaline phosphatase at 1, 4, 7, 14 days. RESULTS AND CONCLUSION:The number of bone marrow mesenchymal stem cells in the two groups was increased with the increasing time, and the control group had more cells than the experimental group at 7 days (P<0.05). There was no significant difference between the two groups at other time points. The alkaline phosphatase activity was increased with the increasing culture time, and the experimental group had a higher activity than the control group at 14 days (P<0.05). There was no significant difference between the two groups at other time points. Experimental findings indicate that Bio-Gide col agen membranes can promote the proliferation and the osteogenetic differentiation of bone marrow mesenchymal stem cells.
