Aim:The aim of the present study was to further elucidate the mechanism of theprotective role of fluvastatin on diabetic ***:Streptozotocin-induced diabetic rats were treated daily with fluvastatin (4 mg/kg body weight) *** animals were killed 4 weeks later and urine and blood samples *** kidney tissues were removed and subjected to the *** glomerular mesangial cells (GMC) were cultured under normalglucose (5.5 mmol/L),high glucose (HG,30 mmol/L),HG+AG490 (10 μmol/L),orHG with fluvastatin (1 μmol/L).Glomeruli or the GMC lysate was immunoprecipi-tared and/or immunoblotted with antibodies against Janus kinase 2 (JAK2),SH2-domain containing tyrosine phosphatase-1 (SHP-1),phosphospecific SHP-2,andsignal transducer and activators of transcription (STAT),***-forming growth factor-β(TGF-β1) mRNA was measured by *** proteinsynthesis of TGF-β1 and fibronectin in the culture medium of GMC was detectedby ***:The phosphorylation levels of JAK2,STAT1,STAT3,andSHP-2 increased significantly,and SHP-1 phosphorylation was reduced in glom-eruli of diabetic *** with fluvastatin reduced phosphorylation levelsof JAK2,STAT1,STAT3,and SHP-2 in glomeruli of diabetic rats,but it had noeffect on the dephosphorylation of *** exposure of GMC to 30 mmol/Lglucose caused the activation of JAK2,STAT1,STAT3,and *** upregulatedTGF-β1 expression and increased protein synthesis of *** highglucose-induced changes were suppressed by fluvastatin,as well as AG490,aJAK2 ***:The regulation of the phosphorylation of JAK/STATby fluvastatin may be responsible for its renal protective effects on diabeticnephropathy.

Catiline, Ibsen’s first play, has often been undervalued. Ibsen’s comments on this play that the ideas he expressed in this juvenile attempt are still what he thinks of after he has made great achievements in dramatic creation exactly show its true value. To a large extent, it is Catiline’s persistent pursuit of his ideal that may have moved the dramatist who has throughout his own life pursued his own ideal. What’s more, Ibsen may also have noticed the similar ethical dilemma that faces him and Catiline: the contraction between his earthly duties and his pursuit of the ideal.

This paper is a continuation of the study of the algebraic speed for Markov processes. The authors concentrate on algebraic decay rate for the transient birth-death processes. According to the classification of the boundaries, a series of the sufficient conditions for algebraic decay is presented. To illustrate the power of the results, some examples are included.

Objective To investigate the effects of simvastatin on membrane ionic currents in left ventricular myocytes after acute myocardial infarction (AMI,so as to explore the ionic mechanism of statin treatment for *** Fourty-five New Zeland rabbits were randomly divided into three groups:AMI group,simvastatin intervention group （statin group） and sham-operated control group （CON）.Rabbits were infarcted by ligation of the left anterior descending coronary artery after administration of oral simvastatin 5 mg·kg-1·d-1 （Statin group） or placebo （AMI group）for 3 ***-four hours later,single ventricular myocytes were isolated enzymatically from the epicardial zone of the infracted *** cell patch clamp technique was used to record membrane ionic currents,including sodium current (INa),L-type calcium current (ICa-L) and transient outward potassium current (Ito).Results①There was no significant difference in serum cholesterol concentration among three groups.②The peak INa current density （at-30 mV） was significantly decreased in AMI group （-23.26±5.18） compared with CON （-42.78±5.48,P23±5.45） compared with AMI group （PCa-L current density （at 0 mV） was significantly decreased in AMI group （-3.23±0.91） compared with CON （-4.56±1.01,Pto current density（at +60 mV） was significantly decreased in AMI group（10.41±1.93）compared with CON （17.41±3.13,P21±2.42）compared with AMI group （PNa,ICa-L and Ito.Pretreatment with simvastatin could attenuate this change without lowering the serum cholesterol level,su

Let B^Hi,Ki ={ Bt^Hi,Ki, t ≥ 0}, i= 1, 2 be two independent bifractional Brownian motions with respective indices Hi ∈ （0, 1） and K∈ E （0, 1]. One of the main motivations of this paper is to investigate f0^Tδ（Bs^H1 ,K1 - the smoothness of the collision local time, introduced by Jiang and Wang in 2009, IT = f0^T δ（Bs^H1,K1）ds, T 〉 0, where 6 denotes the Dirac delta function. By an elementary method, we show that iT is smooth in the sense of the Meyer-Watanabe if and only if min{H-1K1, H2K2} 〈-1/3.
