Objective To analyze the efficacy of rosuvastatin on the patients with hyperlipidemia and hypertension.Methods From March 2011 to June 2012,112 cases with hyperlipidemia and hypertension in our hospital were enrolled in this study.Patients were randomly divided into treatment group and control group (56 patients,each).Patients in control group were treated with oral amlodipine 5 mg/d.Patients in treatment group were treated with oral rosuvastain 10 mg/d and oral amlodipine 5 mg/d.One month after the treatment,the levels of blood pressure,total cholesterol (TC),tryglyceride (TG),low density liporotein (LDL-C),high density lipoprotein cholesterol (HDL-C),high sensitivity C-reactive protein (hsCRP) were determined.The occurrence of adverse effects were observed.Results One month after treatment,systolic blood pressure and diastolic blood pressure were significantly decreased in both two groups compared with pre-treatment [Control group:(135.2±9.51)mm Hgvs.(59.2±7.3)mm Hg,(88.8±5.2)mm Hg vs.(99.5±8.3)mm Hg,t=4.95,2.87; Treatment group:(130.2±5.5)mm Hg vs.(160.3±9.3)mm Hg,(86.7± 10.2)mm Hg vs.(99.7±8.3)mm Hg,t=5.03,2.94,all P＜0.01],but more declines were found in treatment group than in control group(t=3.96,3.42,both P＜0.001).The levels of LDL-C,TG and TC were significantly decreased in both two groups compared with pre-treatment [Control group:(2.64±0.72)mmol/L vs.(3.97±0.84)mmol/L,(1.89±0.25)mmol/L vs.(2.56±0.45)mmol/L,(4.23±0.56)mmol/L vs.(7.36±0.48)mmol/L,t=2.58,3.03,2.36,P=0.013,0.004,0.022;Treatment group:(1.75 ± 0.68) mmol/L vs.(3.85 ± 0.79) mmol/L,(1.71 ± 0.18) mmol/L vs.(2.63±0.42)mmol/L,(3.18±0.47)mmol/L vs.(7.20±0.56)mmol/L,t=2.77,3.16,2.59,P=0.008,0.003,0.012,respectively],but more declines were observed in treatment group than in control group(t=6.73,4.37,10.70 respectively,all P＜0.05).The HDL-C concentrations were increased in both two groups compared with pre-treatment [Control group:(0.97±0.26)mmol/L vs.(0.75±0.31)mmol/L,t=2.89,P=0.006; Treatment group:(1.09±0.23)mmol/L vs.(0.72±0.24)mmol/L,t=3.01,P=0.004],but more increment were observed in treatment group than in control group(t=2.59,P＜0.05).The hsCRP concentration was significantly reduced in treatment group compared with pre-treatment [(1.32±0.17) mg/L vs.(4.97±0.13) mg/L,t=4.40,P＜0.001].There were no significant differences in liver and kidney function between the two groups.Serious adverse effects were not found.Conclusions Rosuvastatin combined with routine antihypertensive therapy can effectively decrease the levels of serum LDL-C,TG,hsCRP; increase serum HDL-C concentration and blood pressure can be effectively controlled.

OBJECTIVE To investigate the pathogens in the early period after heart transplantation and analyze their drug-resistance.METHODS The pathogens in the early period after heart transplantation were identified and their drug-resistance was analyzed.RESULTS From all of the 121 pathogens,the rate of G-bacilli was 73.6%,the rate of G+ cocci was 17.4%and the rate of fungi was 9.1%;G-bacilli mainly consisted of Klebsiella pneumoniae,Enterobacter cloacae,Acinetobacter baumannii,Pseudomonas aeruginosa and Escherichia coli.G-bacilli showed higher sensitive rates to sulbactam/cefoperazone,cefepime,piperacillin/tazobactam and ceftazidime than to cefotaxime.All G-bacilli showed sensitive to imipenem except Pseudomonas aeruginosa.G+ cocci mainly consisted of negative coagulase Staphylococcus,Staphylococcus aureus and Enterococcus.Fungi mainly consisted of Candida,and they were sensitive to fluconazole,itraconazole and amphotericin B.CONCLUSIONS To observe the pathogens in the early period after heart transplantation and analyze their drug-resistance are important to control and prevent the infection efficiently for the heart transplantation recipients.

Objective To evaluate the subclinical dysfunction of left ventricle (LV) induced by anthracycline(ATC) in patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL) by two-dimensional speckle tracking echocardiography (2DSTE) as well as real-time three-dimensional echocardiography (RT3DE).Methods Traditional echocardiography images and RT3DE images were acquired from 59 patients with DLBCL before,after the completion of two cures(100 mg∕m 2)and four cures of the regimen(200 mg∕m 2).LV global longitudinal strain(GLS),global circumferential strain(GCS),LV apical rotation and basal rotation,LV end-diastolic volume (EDV),end-systolic volume (ESV),stroke volume(SV) and ejection fraction(EF)were calculated simultaneously.Results Compared with baseline, LV apical rotation and basal rotation reduced significantly after two cures and four cures of therapy [LV apical rotation:(5.34±1 .80)°vs (3.80±1 .45)°vs (2.96±1 .1 8)°;LV basal rotation:(-3.32±1 .14)°vs (-2.65±1 .12)°vs (-2.56±1 .19)°;both P <0.01].LV GLS and GCS decreased significantly till four cures of treatment compared with those at baseline[GLS:(-21 .62±2.5 1)% vs(-20.1 7±2.74)%;GCS:(-26.34±4.76)% vs (-23.27 ±4.73)%;both P <0.01].The alternation on EDV,ESV,SV and EF manifested no visible degradation during the whole procedure (P > 0.05 for all). Conclusions Cardiotoxicity during the early phase of anthracycline treatment can be detected via 2DSTE prior to the traditional echocardiographic expression of ventricular systolic function.The left ventricular rotation index seems to be more sensitive than strain parameters for the estimation of early cardiac injury in patients with ATC chemotherapy.There is no safe dose for anthracycline in all patients with DLBCL treated with anthracycline even at lower doses.

BACKGROUND:Circular RNAs(circRNAs)play important roles in a variety of diseases or tumors,and recent findings have revealed that circRNAs are abnormally expressed in knee osteoarthritis and are involved in disease progression through microRNA/mRNA regulation. OBJECTIVE:To investigate the effect of circRNA WD repeat containing protein 1(circ-BRWD1)/miR-488-3p/DNA methyltransferase 3A(DNMT3A)on the proliferation and apoptosis of chondrocytes in knee osteoarthritis. METHODS:Real-time fluorescence quantitative PCR was performed to detect the expression of circ-BRWD1,miR-488-3p,DNMT3A in knee osteoarthritis chondrocytes.Cells were divided into si-NC group,si-circ-BRWD1 group,vector group,circ-BRWD1 group,si-circ-BRWD1+anti-miR-NC group,si-circ-BRWD1+anti-miR-488-3p group,miR-NC group,miR-488-3p group,anti-miR-NC group,anti-miR-488-3p group,miR-488-3p+vector group,miR 488-3p+DNMT3A group.Real-time fluorescence quantitative PCR was used to detect circ-BRWD1,miR-488-3p,DNMT3A expression,MTT and flow cytometry assay were used to detect cell proliferation and apoptosis.Western blot assay was used to detect DNMT3A and proliferation/apoptosis-related protein expression.Dual luciferase reporter assay was used to Dual luciferase reporter assay to detect the targeting relationship of circ-BRWD1 with miR-488-3p and miR-488-3p with DNMT3A. RESULTS AND CONCLUSION:circ-BRWD1 and DNMT3A were highly expressed and miR-488-3p was lowly expressed in knee osteoarthritis chondrocytes compared with normal chondrocytes.Knockdown of circ-BRWD1 or overexpression of miR-488-3p inhibited proliferation and induced apoptosis in knee osteoarthritis chondrocytes.circ-BRWD1 targeted negative regulation of miR-488-3p and inhibition of miR-488-3p reversed the effect of circ-BRWD1 knockdown on chondrocyte proliferation and apoptosis in knee osteoarthritis.miR-488-3p targeted negative regulation of DNMT3A and upregulation of DNMT3A reversed the effect of miR-488-3p overexpression on chondrocyte proliferation and apoptosis in knee osteoarthritis.circ-BRWD1 could regulate the expression of DNMT3A by regulating miR-488-3p.To conclude,knockdown of circ-BRWD1 inhibits chondrocyte proliferation and induces apoptosis in knee osteoarthritis,and the mechanism of action may be related to the regulation of miR-488-3p/DNMT3A axis.
