Currently,research and practice in the of hospital management in China are at low level.This paper agrees that the innovation of hospital research management should be based on scientific knowledge management,knowledge communities is a core component of knowledge management implementation in hospitals.This paper descripts the method that how to buide the knowledge community,for example,the types of knowledge community,hospital knowledge system,and the job title based knowledge map and process-oriented knowledge map.

Objective To observe the expression and distribution of angiopoietin-like protein 3(ANGPTL3) in kidney of adriamycin(ADR)-induced nephrotic rats, and to explore the possible association of ANGPTL3 with the development of proteinuria and hyperlipidemia. Methods Adriamycininduced nephrotic rat models were established by a single injection of adriamycin via the tail vein. Immunohistochemical staining (IHS)and dot-ELISA were used to examine the expression and distribution of ANGPTL3 in kidney and the level of ANGPTL3 in serum of ADR rats at day 7,14, 21 and 28 after adriamycin injection. Results (1) In ADR rats, urinary protein and the level of triglyceride and cholesterol in serum increased significantly at day 14 (P

Objective To explore the therapeutic mechanisms of nitric oxide donor (SIN 1) in ischemic acute renal failure (IARF). Methods The effects of SIN 1 on intercellular adhesion molecule 1 (ICAM 1) expression and inflammatory cell infiltration in rat kidney after ischemia/reperfusion (I/R) injury were examined using ICAM 1, ?2 integrin polyclonal antibody, and immunohistochemistry. The renal functions were measured simultaneously. Results Progressive increased expression of ICAM 1 was found in kidneys, especially in vasa recta, after IR injury. ?2 integrin positive cells increased simultaneously in the outer medulla. The two indexes reached the peak values at 24 h after I/R injury. SIN 1 infusion at the beginning of reperfusion could remarkably inhibit the enhanced ICAM 1 expression, reduce the local infiltration of inflammatory cells, and ameliorate the renal functions. Conclusion NO donor can inhibit the renal expression of ICAM 1 and the infiltration of leukocytes after ischemia reperfusion injury, which may play an important role in the treatment of ischemic acute renal failure.

Objective To evaluate the correlation of the depths of detecting arteries vessel in transcranial dopplor(TCD) and child head circumference.Methods Five hundreds and eighty-eight health children were selected at random for the study. TCD ultrasonography was used to detect the optimal depths of arteries, middle and anterior and posterior cerebral arteries for each child, together with the head circumference.Results The data showed that the depths of detecting cerebral arteries significantly changed in different age groups, probably due to the growth of the head circumference.Conclusion There was close relationship between the depths of detecting cerebral arteries and child head circumference, which is of clinical significance.

Objective To observe the impact of transplant nephrectomy on panel reactive antibodies and a secondary renal transplantation.Methods Panel reactive antibodies in 15 patients with a failed renal transplant admitted in our hospital between 2004 to 2007 were measured before transplantation,before and 1 month,6 months,12 months after transplant nephrectomy,and the pathological changes were observed after transplant nephrectomy.Results Panel reactive antibodies was increasing after renal transplantation,and reached the highest level one month after transplant nephrectomy,then grandually got down.New HLA allosensitization sites were discovered after transplant nephrectomy.Large amount of C4d was stained in failed transplant.Conclusion Serum PRA increased after transplant nephrectomy.New HLA allosensitization sites were found,which may be useful in HLA matching.

Objective To establish a simple and sensitive method for the determination of serum copper by spectrophotometry.Methods Nitro-PAPS was used as a coloring agent for serum copper in the presence of surfactants Tween-80 and Triton X-100 and the formed complex was measured by spectrophotometry.Results The maximum absorption wavelength of the complex was 570 nm and the molar absorption coefficient was 7.95?10~4 L/(mol?cm).The lineafity of the method was up to 63.0 ?mol/L and the recoveries ranged from 98.6% to 103.1%.The within-run and between-run CVs were 2.1%-3.3% and 2.7%-3.8%.The method(Y)was compared with an AAS method(X)and a correlation of Y=1.01X -0.27(r=0.998 2)was obtained.A reference interval(x~-?2s)determined with this method on 68 individuals was 9.7-24.1 ?moL/L.Conclusions A simple and sensitive method for serum copper has been established.It may used for the analysis of serum copper in clinical laboratories.
