Objective To study the relationship of the plasma levels of high sensitive C-reactive protein(hs-CRP),adrenomedullin(ADM),brain natriuretic peptide(BNP)and matrix metalloproteinases (MMPs)with severity of heart falure, the left ventricular ejection fraction and the relationship among them in the elderly patients with congestive heart failure(CHF). Methods The blood samples were obtained from 50 patients with congestive heart failure and 24 healthy controls.The plasma level of hs-CRP was measured by immunoturbidometry.The plasma levels of ADM and BNP were determined by radioimmunoassay.The plasma levels of MMP-2 and MMP-9 were measured with ELISA.Left ventricular ejection fraction(LVEF)was measured by echocardiography. Results The plasma levels of hs-CRP, ADM ,BNP and MMP-2,MMP-9 had significantly negative correlation to LVEF(P

Objective To discuss the effects of extract of Ginkgo BilobaLeaves(EGb) on expression of cytokine of renal interstitial fibrosis induced by transforming growth factor-?1 (TGF-?1) and extracellular matrix. Methods Cultured human kidney cells(HKC) were divided into three groups: control group,TGF-?1(8 ng/mL) group,and TGF-?1(8 ng/mL) added EGb(25,50,100,150 mg/L)group.After 72 h,expression of ?-SMA was detected by cell immunochemistry ABC,and collagen type I by Real-time PCR and Western blotting. Results Treated with TGF-?1(8 ng/mL) for 72 h,expression of ?-SMA and collagen type Ⅰ were up-regulated markedly compared with control group.Treated with EGb(25,50,100,150 mg/L)and TGF-?1(8 ng/mL)concomitantly for 72 h,expression of ?-SMA and collagen typeⅠ were down-regulated in dosage dependent manner compared with TGF-?1 group. Conclusion EGb can inhibit expression of ?-SMA and collagen type I in HKC induced by TGF-?1,and the possible mechanism might be related to the inhibition of EGb on renal tubular epithelial-myofibroblast transdifferentiation.

Objective To investigate the correlation between angiotensin converting enzyme(ACE) gene polymorphism and kawasaki disease(KD).Methods A 287 bp Alu fragment in intron 16 of the ACE gene was used as insertion(I)/deletion(D) polymorphism marker. The ACE genotype of 28 children (10 children complicated coronary dilataltion) with KD and 35 healthy controls were detected by polymerase chain reaction (PCR), and ACE concentration in blood serum was measured by ultraviolet-spectrophotometer assay.Results 1.The ACE concentration was significantly higher in KD group than that in healthy control group(P

Objective To reconstruct sparse views CT image based on defective projection data.Methods The position of bad bins in detector determined whether the linear interpolation was applied to the defective projection data.Moreover,reconstruction of air pixels in CT image was achieved rapidly and accurately.Results he experimental results showed that the proposed method could solve the problem from classical ART-TV method that the robustness was unstable due to the different positions of bad bin in CT detector.Conclusion Compared to analytical reconstruction methods,iterative methods can solve the reconstruction problems in this modality so that the radiologist is facilitated to perform image processing and quantitative analysis.

Hepatic fibrosis models were induced by CCl4 in rats. To explore vascular endothelial growth factor (VEGF), transforming growth factor-beta1 (TGFβ1) mRNA expression and bcl-2, Bax protein expression levels of intervention and explore the mechanism of the Aralia chinesis anti-hepatic fibrosis. Sixty male Sprague-Dawlley (SD) rats were randomly divided into six groups: nomal group, model group, high-dose (10 mL x kg(-1)), medium-dose (7.5 mL x kg(-1)), low-dose (5.0 mL x kg(-1)) of A. chinesis treated group and colchicine treated group. The change of liver histopathology was observed by HE and Masson staining. The mRNA of VEGF, TGF-β1 were detected by RT-PCR. The protein of Bcl-2 and Bax were detected by Western blot. In the model group liver cell obvious degeneration, necrosis, a large number of collagen fibers of the cable hyperplasia, part visible pseudolobule formation. A. chinesis large, medium, low-dose group and colchicine group liver cell degeneration and necrosis reduced A. chinesis small, medium, and high-dose group was gradually reduced trend and A. chinesis large, middle dose group degree of reduction is particularly significant. Compared with model group, A. chinesis of large, medium and small dose group and colchicine group VEGF mRNA expression, A. chinesis of large, medium-dose group TGF-β1 mRNA expression reduce (P < 0.05); compared with colchicine group, A. chinesis of large, middle dose group of VEGF mRNA expression decreased (P < 0.05); A. chinesis of large, middle dose group of TGF-β1 mRNA expression decreased (P < 0.01), and compared with colchicine group, large dose group of of TGF-β1 mRNA expression decreased (P < 0.05). Compared with model group, A. chinesis of large, medium and small dose group and colchicine group Bcl-2 protein expression reduce (all is P < 0.05). But A. chinesis of large, medium and small dose group and colchicine group of Bax protein expression were increased (P < 0.05). A. chinesis regulation of VEGF, TGF-β1 may prevent the activation of hepatic stellate cells, liver tissue by up regulating the anti-apoptotic protein Bax and down pro-apoptotic protein Bcl-2 expression, thereby to improve the degree of liver fibrosis.

The systematic position of Fritillaria hupehensis has been in dispute. Phylogentic analyses were conducted on sequences of ITS, rpl16, matK sequences for species of F. hupehensis and allies. Lilium davidii was designed as outgroup. The analyses were performed using MP and ML methods. Conclusions could be achieved as follow. The topologies of MP and ML are consistent. The samples of F. hepehensis from different places form a supported clade with a strong bootstrap. And then form a strongly supported clade with F. anhuiensis, F. monantha. The results suggests that although F. hupehensis has a closet relation with the two ones, it exists some difference.
