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.

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.

Objective To investigate the clinical effects of prostaglandin E1 (PGE1) in the treatment ot chronic renal failure in the 2nd ～ 4th period.Methods 128 patients with CKDs at stage 2 to 4 were selected and randomly divided into the observation group and control group,64 cases in each group.Patients in control group were given routine drug treatment,and patients in observation group were given PGE1 on the basis of the control group.They all treated for 3 months.Renal function indicators before and after treatment,curative effect and adverse reaction were compared.Results There were no statistical differences in renal function indicators before treatment in two groups (t =0.27 ～ 0.95,P ＞ 0.05).After treatment,the 24 hours urinary protein (t =3.41,P ＜ 0.05),creatinine clearance rate (t =4.04,P ＜ 0.05),serum creatinine (t =4.15,P ＜ 0.05),serum urea nitrogen (t =3.92,P ＜ 0.05) between the two groups had statistical differences.Total effective rate of the observation group was 84.37％,which was significantly higher than 57.81％ of the control group (x2 =5.63,P ＜ 0.05).There was no adverse reaction observed in observation group.Conclusion PGE1 might improve patients' proteinuria and renal function in the current situation of lacking effective treatment.

OBJECTIVE: To study the effect of salvianolate on the migration of endothelial cells induced by monocytes. METHODS: Transwell-boydom system was used to test the migration of endothelial cells induced by monocytes. Enzyme-linked immunosorbent assay (ELISA) and RT-polymerase chain reaction (RT-PCR) method were used to determine the effect of salvianolate on the expression of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) and their mRNA of monocytes. RESULTS: The migration of endothelial cells induced by monocytes was facilitated by salvianolate, compared with the control. After the monocytes were treated by salvianolate for 24 hours, the expression of mRNA of VEGF and bFGF was significantly up-regulated, and the expression of VEGF and bFGF was increased. CONCLUSION: The facilitation of salvianolate on the migration of endothelial cells induced by monocytes was observed. Salvianolate stimulates the expression of VEGF and bFGF and their mRNA of monocytes, and salvianolate may have the role of inducing migration of endothelial cells by working on these two factors.

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.

In order to study the physiological action of glucocorticoid receptor (GR) in intact animal, an animal model of GR depletion was developed in the rat by mifepristone (RU486), an antagonist of GR. Mifepristone 50 mg/kg body weight mixed in polyvinyl alcohol (PVA) was injected intramuscularly every 12 h in order to maintain the plasma mifepristone at the concentration of about 10-6mol/L for 72 h. In the meanwhile, the plasma corticosterone (B) was stabilized at about 15 ?g/dl by unilateral adrenalectomy 3 d before. In this model mifepristone occupied 88.1 ?10.7% of the total GR in hepatic, brain cytosol and thymocytes as measured by the exchange assay with [3H]dexamethasone (Dex) as ligand. Some indexes of glucocorticoid response were measured in the control, model and bilateral adrenalectomized (AdxT) rats. The polymorphonuclear eosinophil leukocyte (PME) count in blood and phospholipase A2(PLA2) activity in serum were decreased and tyrosine aminotransferase (TAT) activity of the liver was elevated in the control rats after stress provoked by epinephrine, but these changes were reversed in the model rats as well as in the AdxT rats. Thus it may be concluded that decrease of GR to about 12% may result in adrenoglucocorticoid insufficiency in spite of the normal functioning adrenal gland and high plasma level of B. So far as we know this is the first success to produce experimental endocrine insufficiency in a receptor depletion animal model and to quantitate the occupational threshold of about 12% of the total GR in rats.
