AIM: To study the expression of endostatin in ischemic myocardium of myocardial infarction(MI) rats in various periods and the correlation with VEGF expression and microvascular density(MVD).METHODS: Thirty-two male Sprague-Dawley rats after myocardial infarction were randomly divided into 7,14,21 and 28 days group.The sham group was normal control group(eight rats in each group).The expression of endostatin,VEGF and MVD in ischemic myocardium were observed by immunohistochemistry.RESULTS: The expression of endostatin significantly increased in the ischemic myocardium after MI,peaked at 7 days,then gradually decreased at 14,21 and 28 days.The endostatin level at 28 days was the same as the shams.The changing trends of expression of endostatin in ischemic myocardium after MI were similar to that of VEGF and were significantly correlated with the MVD.CONCLUSION: The expression of endostatin increased in ischemic myocardium of myocardial infarction rats.The changing trends of endostatin were similar to that of VEGF and positively correlated with the MVD.These data suggest that endostatin may modulate ischemic myocardium angiogenesis after myocardial infarction.

To investigate the influence of Bufei Jianpi Granule (BJG) on immune function in mice. Spleen cellular proliferation and the activities of IL-1 and IL-2 in mice were observed. The differences of spleen cellular proliferation stimulating by Con A, the secretion of IL-2 from spleen cells and the secretion of IL-1 from celiac macrophage were significant among BJG group, the control group and the water-drinking group. [Conclusion] BJG can promote the function of cellular immune and the secretion of IL-1 and IL-2 from immune active cells in mice.

Objective To discuss the feasibility of developing psychological pressure assessment tools coping with hospitalized patients based on Neuman systems model. Methods We analyzed the fea-sibility of developing assessing tools specifically by theoretical analysis, literature review and case study.Results It was proved that Neuman systems model was suitable for guiding the development and applica-tion of assessment tools for evaluating the psychological pressure. Conclusions Neuman Systems Model could effectively evaluate the psychological pressure of non-psychiatric settings. Therefore, it can be con-cluded that the model is suitable for developing the psychological assessment tools for hospitalized patients.

Objective To investigate the pathogenic features and antibiotic resistance profile of nosocomial and community-acquired spontaneous bacterial peritonitis (SBP) in liver cirrhosis patients.Methods Two hundred and twenty-six cirrhotic patients with SBP who were admitted to Beijin Ditan Hospital from January 2001 to December 2008 were recruited into this study. The bacterial identification and drug susceptibility were performed. The data were analyzed by Chi square test and t test. Results Eighty-six(38.0% ) patients were diagnosed with nosocomial SBP and 140 (62.0%)were diagnosed with community-acquired SBP. The proportion of Child-Pugh Class C cases in patients with nosocomial SBP was higher than patients with community acquired SBP (97.7% vs. 82.8%; x2= 11. 489, P=0.001). Mortality rate in patients with nosocomiat SBP was also higher than patients with community acquired SBP (50. 0% vs. 30. 0%; x2 =9. 081,P=0. 003). Total 28 species (232strains) of bacteria were isolated from these patients. 77.5 % (69/89) of the nosomial SBP cases and 76.9% (110/143) of community-acquired SBP cases were caused by Gram-negative bacteria (mainly were Escherichia coli and Klebsiella pneumoniae). 19.1% nosocomial SBP cases and 21. 8%community-acquired SBP cases were caused by Gram-positive bacteria. Fungus infections accounted for 3.4% and 1.4% of these two population, respectively(P＞0.05). In patients with nosocomial SBP,19 out of 32 Escherichia coli stains and 5 out of 14 Klebsiella pneunmoniae strains were extended spectrum β-lactamase (ESBL) positive, while among 60 Escherichia coli stains and 32 Klebsiella pneunmoniae strains, only 11 Escherichia coli stains were ESBL positive (P＜0.05). The resistance rates of Gram-negative strains to cephalosporin and quinolone in nosocomial SBP patients were both higher than those in community-acquired SBP patients(P＜0. 05), but all Gram-negative isolates were sensitive to imipenem (P＞ 0. 05). No Gram-positive isolates resistant to vancomycin were found.Conclusions The liver cirrhosis patients with Child-Pugh Class C are vulnerable to nosocomial SBP and the prognosis is poor. Although the pathogenic spectrum are similar in cirrhotic patients with nosocomial and community-acquired SBP, which mainly are Escherichia coli and Klebsiella pneumoniae, the percentage of ESBL producing strains is higher in nosocomial SBP patients compared to that in community-acquired SBP patients.

Purpose:To study the biological effects of high secreted canstatin on human umbilical vein endothelial cells (HUVEC) and tumor model. Methods:Hypoxic responsive elements (HREs) were inserted in the upper stream of canstatin cDNA of a recombinant vector we constructed in a former research. The new recombinant vector named pCMV-3HRE-CEAS-Cans was transferred into A549 cells by cationic liposome; canstatin mRNA expression in the transformed cells under oxic and anoxic condition was detected by Taqman PCR. Then we designed a co-cultured assay: HUVECs were co-cultured with recombinant vector transformed A549 cells with Transwell plates, and the proliferation and apoptosis of co-cultured HUVECs were evaluated with 3H-thymidine incorporation method, TUNEL method respectively. Finally the vector was introduced into tumor tissues of lung cancer-bearing nude mice, and the biological activity in the tumor tissues was tested by micro-vessel count (MVC). A vector of canstatin we constructed before was used as controls in above experiments.Results:The pCMV-3HRE-CEAS-Cans vector was successfully constructed and transferred into A549 cells. canstatin mRNA was detected both in the recombinant vector transformed A549 cells and the pCMV-CEAS-Cans transformed A549 cells, moreover the expression of canstatin in the new vector transformed A549 was significantly higher than that of the controls under hypoxic condition. ~(3)H-TdR intake rate of HUVECs was decreased markedly, and a large amount of them underwent apoptosis when they were co-cultured with recombinant vector transformed A549 cells. Significant differences of ~(3)H-TdR intake rate and apoptotic rate of co-cultured HUVEC were found between pCMV-3HRE-CEAS-Cans group and any of the controls (P

Objective To construct an effective expression system for secretory canstatin, and to study its biological effects. Methods Canstatin cDNA was ligated with the cDNA of CEA signal peptide by SOE PCR, and the new fused fragment was cloned into eukaryotic expression vector pCMV-Script. The recombination vector pCMV-CEAS-Cans was transferred into human umbilical vein endothelial cells (HUV-EC) and human lung adeno-carcinoma cell line A549 by cationic liposome. The expression of canstatin mRNA together with CEAS mRNA in the transformed cells were detected by real time PCR method. Results Canstatin mRNA was detected in both transformed cells. The 3 H-TdR intake rate in pCMV-CEAS-Cans transformed HUVEC cells is significant lower than that of the pCMV-Script transformed cells (P

Objective To summarize the clinical experience of nasal endoscopic treatment for refractory epistaxis. Methods .A retrospective analysis was made on 258 patients with refractory epistaxis treated with intranasal endoscopic exploration and hemostatic treatment from January 1998 to December 2004 in this hospital. Results .Hemorrhage was found on the nasal septum and the lateral nasal wall in 118 and 47 patients, respectively. Nose bleeding resulted from intranasal tumor in 8 patients. The site of bleeding was not clearly identified in 85 patients. Of the 258 patients, 257 responded to the treatment (99.6%) and 1 died ( 0.4%).Recurrent bleeding occurred in 43 patients. The incidence of recurrent bleeding was significantly higher in patients with unknown bleeding sites than in clearly diagnosed patients (?2=17.689,P=0.000). Conclusions .The emphasis of nasal endoscopic treatment for refractory epistaxis should be laid on the initial management, during which the bleeding site should be carefully identified. For patients with repeated nose bleeding, a combination treatment, including endoscopic filling-up of the anterior nasal cavity, endoscopic embolization of anterior and posterior nose, or embolization of the internal maxillary artery, is necessary.
