DNA replication and RNA biogenesis happen in the cell nucleus,while protein synthesis occurs in the cytoplasm. Integration of these activities depends on function proteins′ selective transport between the two sub-dimensions. It is a signal mediated process, which needs energy and the participation of soluble factors. By introduction of progress on function protein regulated nuclear translocation, its potential medical application has been explored. With deeper investigation in this field, it will significantly promote the design of anti-virus and gene vector therapy.

Objective To determine whether specific angiotensin-conventing enzyme inhibitor with ramipril would affect ventricular arrhythmia generation in rabbits after myocardial infarction and discuss the mechanism of its antiarrhymic efficacy.MethodsTwenty-four New Zealand rabbits (Wuhan Laboratory Animal Research Center) were separated into 3 groups:sham-operated (SHAM) group (n =8 ),myocardial infraction (MI) group ( n =8) and myocardial infraction with ramipril (RAM) group ( n =8).SHAM group received a median sternotomy without left ventricular coronary artery ligation.MI and RAM groups' rabbits received a median sternotomy followed by left coronary artery ligation. The successful anterior MI was confirmed by elevation of the ST segment with more than 0.2 mV in lead Ⅱ and Ⅲ.After MI,RAM group rabbits were fed with ramipril [ 1mg/ ( kg · d) ]by intragastric administration for 12 weeks.Before and after MI 12 weeks in three groups.Ventricular tachycardia or fibrillation episodes and the monophasic actionpotential duration in epicardium,mid-myocardium and endocardium cadiocytes were recorded.The statistical technique was t-test and ANOVA.Results Ventricular tachycardia or fibrillation episodes were markedly decreased in RAM group than that in MI group after 12 weeks [ (2.6 ± 0.8) vs.(12.4 ± 2.9),P ＜0.05 ].After MI 12 weeks,the action potential duration of repolarization 90％ (APD90) of three-tier ventricular myocytes in MI group was prolonged than that before MI [ (258.2 ±21.1 ) vs.(230.1 ±23.2),( 278.0±23.8 ) vs.(245.8±25.4),(242.6±22.7) vs.(227.0±21.7),P＜0.05]; however,it was not significant difference between before and after MI 12w in RAM group (P ＞ 0.05 ).Moreover,the transmural dispersion of repolarization(TDR) was markedly increased after MI 12w in MI group than in SHAM and RAM group [ (36.2 ± 10.2 ) vs.( 18.7 ± 6.2 ),(24.9 ± 8.7 ),P ＜ 0.05 ]; but the TDR was not significant difference between RAM and SHAM group ( 18.7 ± 6.2 ) vs.( 24.9 ± 8.7 ),P ＞ 0.05].ConclusionsRamipril significantly reduced the malignant arrhythmia incidence in rabbits after MI.Mended the abnormal TDR was the mechanism for ramipril to therapy.

Objective:To explore the correlation between serum cystatin C (Cys C)content and renal function in aged patients with benign prostatic hyperplasia (BPH).Methods:Clinical data of 237 aged BPH patients were retro-spectively analyzed.According to international prostate symptom score (IPSS),they were divided into mild group (n=25),moderate group (n=67)and severe group (n= 145);another 110 patients without prostatic hyperplasia were enrolled as normal control group in the same period.Levels of serum Cys C,blood urea nitrogen (BUN),ser-um creatinine (Scr),fasting blood glucose (FBG),blood lipids and prostate-specific antigen (PSA)were measured in all groups,and prostate volume (PV)was calculated.Results:Compared with normal control group,PV signifi-cantly rose [(18.94±4.62)ml vs.(40.09±12.72)ml],maximum urinary flow rate (Qmax)significantly reduced [(18.67±4.60)ml/s vs.(9.93±3.54)ml/s],and serum Cys C level significantly increased [(1.03±0.23)mg/L vs.(1.53±0.61)mg/L]in BPH group,P <0.01 all.Subgroup analysis indicated that serum Cys C levels in mild, moderate and severe group [(1.32±0.45)mg/L,(1.42±0.32)mg/L,(1.61 ±0.64)mg/L]were significantly higher than that of normal control group,P <0.01 all;and that of severe group was significantly higher than those of mild group and moderate group (P <0.01 or P <0.05).Pearson correlation analysis indicated that serum Cys C level was positively correlated with of age,SBP,DBP,FBG,BUN,Scr,PV and IPSS (r=0.179~0.580,P <0.05 or P <0.01),and inversely correlated with Qmax (r=-0.243,P <0.05)in BPH patients.Conclusion:Serum Cys C level significantly rise,and related with BPH degree,correlated with renal function in aged BPH patients,which can be used to predict renal function of these patients.

Objective To explore the effects of amlodipine,perindopril and valsartan on plasma adiponectin and retinol binding protein 4 in elderly patients with essential hypertension.Methods From March 2007 to July 2010,238 elderly patients with essential hypertension were selected and 193 cases completed this study.Patients were randomly divided into 3 groups:amlodipine group (n=68),perindoprilgroup (n=60) and valsartan group (n=65).Patients in each group were treated with amlodipine,perindopril and valsartan respectively for at least 12 weeks.The changes in blood pressure,heart rate,body height,body mass index (BMI),abdominal circumference,waist circumference (WC),levels of blood lipids,plasma adiponection and retinol binding protein 4 were observed before and after treatment.Results Compared with pre-treatment,systolic blood pressure in 3 groups were significantly decreased after treatment (all P＜0.01).There were no significant differences in blood pressure among 3 groups after treatment (all P＞0.05).Compared with pre treatment,plasma adiponectin level was significantly increased in perindopril group and valsartan group after treatment [(7.4±1.8) μg/L vs.(8.3± 1.8) μg/L,(7.5±1.7) μg/L vs.(8.4±1.9)μg/L,both P＜0.01].Plasma adiponectin level was higher in perindopril group and valsartan group than in amlodipine group after treatment [(8.3±1.8) μg/L vs.(7.6±1.8) μg/L,(8.4±1.9) μg/Lvs.(7.6±1.8) μg/L,both P＜0.05].Compared with pretreatment,plasma retinol binding protein 4 level in 3 groups were all decreased after treatment,and the decrements had significant differences in perindopril group and valsartan group (both P＜0.01) but had no difference in amlodipine group (P＞0.05).Plasma adiponectin retinol binding protein 4 levels were lower in perindopril group and valsartan group than in amlodipine group after treatment[(36.6± 14.2) μg/L vs.(42.7± 13.8) μg/L,(36.3±14.1) μg/L vs.(42.7±13.8) μg/L,respectively,both P＜0.01].Conclusions Perindopril and valsartan play important roles in cardiovascular protection beyond the antihypertensive effects by increasing plasma adiponection level and decreasing plasma retinol binding protein 4 level in elderly patients with hypertension.
