Objective To study the protective effect of fluvastatin on cardiac remodeling and cardiac function, and to investigate its effect on Von Willebrand factor (VWF). Methods The rat model of cardiac heart failure (CHF) was in-duced by isoproterenol injection (170 mg/kg) via subcutaneous. Eighteen model rats were randomly divided into fluvastatin (20 mg ·kg-1·d-1) group, placebo group and control group. Rats were treated with normal saline in placebo group and control group. After 6-week treatment, the structure and function of hearts were measured by echocardiography in three groups. The ventricular weight index, the serum levels of VWF and B-type natriuretic peptide (BNP) were measured by ELISA assay. The levels of VWF mRNA in cardiac muscle were measured by RT-PCR. Results Compared with control group, the val-ues of left ventricular end-diastolic diameter (LVEDD) and left ventricular end systolic diameter (LVESD) were significantly increased in placebo group and fluvastatin group, while values of left ventricular ejection fraction (LVEF) and left ventricular ejection fraction shortening (LVFS) were significantly decreased (P<0.05). The values of left ventricular wet weight/body weight (LVRW) and right ventricular wet weight/body weight (RVRW) were increased in placebo group and fluvastatin group. The expression of VWF mRNA in cardiac tissues was enhanced significantly (P<0.01). Compared with placebo group, the values of LVEDD, LVRW and RVRW were significantly decreased in fluvastatin group. The expression of VWF mRNA in cardiac tissues was significantly decreased (P<0.01), and the values of LVEF and LVFS were significant increased in fluvas-tatin group (P<0.05). The level of VWF was positively corrected with BNP(r=0.996). Conclusion Fluvastatin could im-prove the cardiac function and cardiac remodeling, which may be by reducing the level of VWF and improving endothelial function.

The aim of this study was to explore the effects of parenteral supplementation with omega-3 fish oil emulsion (Omegaven) on systemic inflammatory response syndrome (SIRS) during the initial stage of severe acute pancreatitis (SAP). In a prospective, randomized and controlled trial, 60 patients with SAP were randomized either to treat with conventional therapy (Con group, n=30) or conventional therapy plus intravenous supplementation with omega-3 fish oil emulsion 0.2 g/kg every day (FO group, n=30). The effects were analyzed by the SIRS-related indexes. The results showed that APACHE-II scores in FO group were significantly lower, and the gap increased much farther after the 4th day than those in Con group (P<0.05). Fluid equilibrium time became shorter markedly in FO group than in Con group (5.1+/-2.2 days vs 8.4+/-2.3 days). In FO group, SIRS scores were markedly decreased and the SIRS state vanished after the 4th day; Plasma level of TNF-alpha was significantly reduced, while IL-10 decreased markedly, most prominently between the 4th and 7th day, and the ratio of IL-10/TNF-alpha raised as compared with Con group (P<0.05). During the initial stage of SAP, parenteral supplementation with omega-3 fish oil emulsion could efficiently lower the magnitude and persistence time of the SIRS, markedly retrieve the unbalance of the pro-/anti-inflammatory cytokines, improve severe condition of illness and may provide a new way to regulate the SIRS.

Objective To detect the expression of Toll-like receptor 9 (TLR9) in pancreatic cancer and to study the effect of CPG ODN2216 on the biological behavior of pancreatic cell carcinoma, and to explore their clinical significance. Methods Immunohistochemical method was used to examine the expression of TLR9 protein in pancreatic cancer tissue and immunofluorescence staining was also performed to detect TLR9 protein expression in pancreatic carcinoma cells. In vitro cell adhesion, wound-healing scrape assay, transwell invasion assay and cell colony formation assay were performed to assess the effect of CPG ODN2216 on the invasive properties of Panc-1 cells. Results TLR9 were highly expressed in the pancreatic cancer tissue and pancreatic carcinoma cells. In vitro experiments as cell spreading assays, cell adhesion, colony formation assay and invasion assays showed the cell adhesion and cell motility properties of CPG ODN 2216 group to be apparently weakened compared with the control group. MTT assay showed cell proliferation ability in the CPG ODN group to be notably decreased, and CPG ODN2216 had inhibitive effects on the growth of panc-1 cells in a dose and time-dependent manner. Conclusions TLR9 gene was correlated with the invasive and metastatic potentials of pancreatic carcinoma. The used of CPG ODN2216 induced the inhibition of migration and invasion of the Panc-1 cell line.

Objective To detect the expression of Toll-like receptor 9 (TLR9) in pancreatic cancer,and to explore its clinical significance. Methods The real-time PCR, Western blotting and immunohistochemistry were used to examine the expression of TLR9 in 30 samples of pancreatic cancer and the adjacent tissues, and 10 samples of normal pancreatic tissues. The relationships of TLR9 with clinicopathological parameters were analyzed. Results Compared with normal pancreatic tissues, the amplification value of TLR9 mRNA expression was 2.32 fold (1.41 ~ 3.22 ) in human pancreatic cancer, was 1.23 fold (1.18 ~ 1.28) in paracancerous tissues, respectively, and the difference was statistically significant (P < 0.05 ). The percentage of positive cells expressing TLR9 protein in human pancreatic cancer tissues,paracancerous tissues and normal tissues were 73.3% (22/30), 33.3% (10/30) and 20.0% (2/10), and the relative expressions of TLR9 protein were 0.780 ±0. 026,0. 400 ±0.018,0. 173 ±0.043 ,respectively, and the difference was statistically significant( P < 0.05 ). The highly expressed TLR9 was positively correlated with the degree of tumor differentiation, TNM stage and lymph node metastasis. Conclusions TLR9 was highly expressed in pancreatic cancer tissues. TLR9 expression plays a role in the canceration of pancreatic tissues.
