Objective To study the impact of alprostadil on serum high-sensitivity C-reactive protein ( hs-CRP) and troponin I( cTnI) in patients with diastolic heart failure.Methods 92 patients with diastolic heart failure were randomly divided into the two groups,the control group and the observation group,46 cases in each group.The control group used the conventional treatment and the observation group on the basis of conventional therapy plus al-prostadil.Two groups were treated for 4 weeks.They were measured filling velocity ratio (E/A) in patients with early and late peak atrial contraction,stroke volume (SV),left ventricular end-diastolic diameter (LVEDD),6min walking distance and serum hs-CRP, cTnI before and after treatment.Results There were no significant difference about LVEDD,E/A and SV(t=0.,0.261,0.445,all P>0.05).After treatment for four weeks,LVEDD were (53.1 ± 5.1)mm and (47.3 ±4.7)mm,LVEDD of the two groups had significantly decreased (t=4.601,9.331,P<0.05, P<0.01),and post-treatment the observation group LVEDD decrease more significantly (t=2.914,P<0.05).After 4 weeks of treatment,the control group after treatment E/A and SV were (0.79 ±0.15) and (72.6 ±5.4),the ob-servation group E/A and SV were (0.85 ±0.14) and (79.5 ±5.9)mL,E/A and SV in both groups were significant-ly elevated (t=3.172,4.710,3.924,5.776,P<0.05,P<0.01),and E/A and SV of post-treatment the observation group increased more significantly (t=3.771,2.840,P<0.05).After treatment,patients 6min walking distance were (383.4 ±47.5)m and (426.1 ±49.1) m,6min walking distance of patients were significantly improved after treat-ment (t=8.776,12.648,P<0.01),and the observation group improved significantly more than that of the control group (t=3.019 2,P<0.05).In the control group,serum hs-CRP patients,cTnI were (21.3 ±4.6) mg/L and (2.13 ±0.52) ng/mL,(13.8 ±4.1) mg/L and (1.05 ±0.38) ng/mL in the observation group.Two groups of patients before treatment serum hs-CRP and cTnI was no significant difference (t=0.527,0.493,all P>0.05).After 4 weeks of treatment,the serum hs-CRP,cTnI were significantly lower in both groups (t=3.612,8.772,2.924, 5.164,P<0.05,P<0.01),and compared with the control,the observation group reduced more significantly (t=3.061,7.114,P<0.05).Conclusion Alprostadil can decrease serum hs-CRP and cTnI of patients with diastolic heart failure.

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.

Cancer, an abnormal cell proliferation resulted from multi-factors,has the highest morbidity and mortality among all the serious diseases. Considerable progress has been made in cancer biology in recent years. Tumor immunology, cancer stem cells (CSCs), autophagy, and epithelial-mesenchymal transition (EMT) have become hot topics of interests in this area. Detailed dissection of these biological processes will provide novel directions, targets, and strategies for the pharmacological evaluation, mechanism elucidation, and new drug development of traditional Chinese medicine.
