ncreased. But it remains controversial how vaspin is correlated with insulin sensitivity. More studies based on large population are needed to identify the associ-ation between vaspin and insulin sensitivity.

Astrocyte elevated gene (AEG) -1 is cloned as a human immunodeficiency virus (HIV) -1-inducible and tumor necrosis factor-alpha (TNF-α)-inducible transcript in primary human fetal astrocytes (PHFA) by a rapid subtraction hybridization approach. AEG-1 has been reported to be up-regulated in various types of human cancers. Multivariate analyses indicat that AEG-1 correlates with the ability of growth, invasion, metastasis, angiogenesis and chemoresistance of tumors. AEG-1 over-expression activates the PI3K-Akt,nuclear factor kappa B (NF-κB) and Wnt-β-catenin signaling pathways in several crucial aspects of tumorprogression. AEG-1 represents a viable potential target for the therapy of human cancers.

Bidding invitation and procurement of medical equipment is one of the most important works in hospital.It can increase the working efficiency to hold the key taches of medical equipment procurement from 4 aspects including the science of decison-making,the comfirmability of bidding invitation,the right choice of the way of bidding,etc.So some important taches of medical equipment procurement are analyzed and discussed and some points for attention are raised.[Chinese Medical Equipment Journal,2008,29(2):76-77]

Objective: To investigate the expression and subcellular localization of G protein-coupled receptor 30 (GPR30) in Ishikawa endometrial adenocarcinoma cells. Methods: The expressions of GPR30 mRNA and protein in Ishikawa cells were detected by RT-PCR, Western-blotting and immunofluorescence assay. The positive expression rate of GPR30 in the cell membrane and cytoplasm was determined by flow cytometry (FCM). The subcellular localization of GPR30 labeled with colloidal gold was observed under a transmission electron microscope. Results: The expressions of GPR30 mRNA and protein were both detectable and predominately localized in the cell membrane and cytoplasm of Ishikawa cells. The positive expression rate of GPR30 protein in the cytoplasm [(20.10±0.13)%] was significantly higher than that in the cell membrane [(8.54±0.17)%] (P < 0.01). The subcellular localization of GPR30 protein was mainly in the mesh-like network of cytoplasm, which may refer to rough endoplasmic reticulum. Conclusion: The expression level of GPR30 is higher in cytoplasm than in cell membrane of Ishikawa cells. GPR30 is predominantely localized in the rough endoplasmic reticulum of Ishikawa cells, which suggests an important role of GPR30 in endometrial adenocarcinoma. Copyright© 2011 by TUMOR.

OBJECTIVE To investigate the clinical distribution and antibiotics resistance of Pseudomonas aeruginosa nosocomial infection after open-heart operation.METHODS The clinical data of 393 patients with nosocomial infection from Jan 2004 to Dec 2007 were analyzed retrospectively.RESULTS There were 57 infected cases caused by P.aeruginosa,and accounted for 14.5% of all infections during period.All infected patients had serious original heart diseases,and received broad-spectrum antibiotic therapy previously.Forty-two patients developed postoperative cardiorespiratory function failure,and 28 patients needed circulatory support.Thirty-six patients prolonged mechanical ventilation time for over 1 week.Results of susceptibility test showed that ciprofloxacin,levofloxacin and piperacillin/tazobactam were the most active antibiotics,followed by tobramycin,netilmicin,gentamicin,meropenem and imipenem/cilastatin.P.aeruginosa presented high resistance to ceftazidime and cefoperazone/sulbactam.CONCLUSIONS P.aeruginosa is one of the most common pathogenic bacteria after open-heart operations in our hospital and presented multidrug resistance.Rational use of antibiotics is important to reduce drug resistant strains.

BACKGROUND: It remains poorly understood regarding the incidence of panel reactive antibody (PRA) production and its influence to renal function and long-term survival in China. OBJECTIVE: To investigate the incidence of PRA after living renal transplant, so as to provide reference for predicting long-term renal survival. METHODS: A total of 54 patients who received living renal transplantation in Beijing Friendship Hospital from March 2005 and October 2007, were selected. PRA, serum creatinine and urea nitrogen level were detected 1-2 years after transplantation. PRA assay was conducted using One Lambda ELISA HLA-Ⅰ +Ⅱ antigen tray. Serum creatinine and urea nitrogen data were offered by clinical laboratory. RESULTS AND CONCLUSION: A total of 12.96% (7/54) patients showed PRA positive after transplantation, with HLA-Ⅱ antibody positive in 6 patients, and HLA-Ⅰ + Ⅱ antibody positive in 1 patient. In these 7 patients, 6 underwent primary transplantation, and PRA negative before transplantation; 1 patient underwent transplantation for the second time, and HLA-Ⅱ antibody positive before transplantation. Creatine and urea nitrogen level were abnormal in 1 patient with HLA-Ⅰ + ⅠⅡ antibody positive and 2 patients with HLA-Ⅱ antibody highly positive. Creatinine and urea nitrogen levels were normal in 4 patients with low level HLA-Ⅱ antibody. Results show that HLA-Ⅰ +Ⅱ antibody positive and high level HLA-Ⅱ antibody affect renal function in living renal recipients, but low level HLA-Ⅱ antibody has no effect on renal function.

BACKGROUND: It is confirmed that panel reactive antibody (PRA) and its immune level is closely related to rejection activation, renal survival rate and the realization of the renal function. Study addressing the relation PRA level and acute rejection has great clinical significance for forecasting acute rejection and improving the renal survival rate.OBJECTIVE: To analyze the relation of PRA and acute rejection prior to and after transplantation by detecting PRA level combined with patient rejection.DESIGN, TIME AND SETTING: Retrospectively case analysis was performed at the Affiliated Beijing Friendship Hospital of Capital University of Medical Sciences from September 1998 to May 2005.PARTICIPANTS: A total of 633 patients receiving renal transplantation were collected, including 348 males and 285 females, aged 16-67 years.METHODS: Company Lymphocyte Tray produced by One Lambda and Biotest were used for this study, serum PRA level was detected prior to and within 2 months after transplantation.MAIN OUTCOME MEASURES: Pre- and post-transplant PRA level and clinical rejection.RESULTS: Totally 591 patients were PRA negative in pre-transplant assay, and 164 patients were positive, 10.32% (61/591) patients occurred acute rejection; 42 patients were PRA positive in pre-transplant assay, and 71.42% (30/42) patients occurred acute rejection. The difference between PRA negative or positive and acute rejection had significance (P < 0.001). 427 patients were PRA negative in both pre- and post- transplant assay, 5.6% (24/427) patients occurred acute rejection. 164 patients were PRA negative in pre-transplant assay, but positive in post-transplant, 42.7% (70/164) patients occurred acute rejection. The comparison of PRA negative pre-transplant and PRA positive post-transplant combined with acute rejection had difference (P < 0.001). The correlation coefficient of pre-transplant PRA and acute rejection was 0.612, which was 0.658 between post-transplant PRA and acute rejection, there was obvious association when P=0.01.CONCLUSION: PRA plays an important role in forecasting renal rejection. The acute rejection probability is higher in patients with positive PRA; in other hand, the probability is lower in patients with negative PRA.

Objective To compare the Panel reactive antibody (PRA) producing incidence in living and cadaveric transplant for forecasting long term survival. Methods Retrospectively analyze post-transplant PRA of 48 living transplant patients ( December 2003-Sepdtember 2007 ), and 258 cadaveric transplant patients( Feburary 2003-June 2007 ), which in both groups were all PRA negative in pre-transplant. PRA was detected using LAT-1240 (OneLambda) and QUICKSCREE&BSCREEN (GTI). Serum creatine/urea nitrogen level was provided by clinical laboratory. Results Four recipients in 48 living transplant patients showed PRA positive(8.33% ), while 62 receipients in 258 cadaveric transplant patients showed PRA positive(24.03% ) ( P ＜0.05 ). Three recipients in 35 male living donor transplant patients showed PRA positive(8.57% ) ,while 23.03% PRA positive in male cadaveric transplant patients (P ＜0.05). In females, 1out of 13 living donor transplant patients showed HLA-Ⅱ positive, whereas 20 out of 106 in cadaveric transplant patients( 18.87% ) ( P ＜ 0. 05). Conclusion The incidence of HLA antibody production was much higher in cadaveric transplant patients than that in those of living donor transplant.
