MicroRNA(miRNA) is involved in virtually all biologic processes, including cellular proliferation, apoptosis, and differentiation. Thus, miRNA deregulation often results in impaired cellular function and disease development, so miRNAs have potential therapeutic relevance. The elucidation of these processes regulated by miRNAs and the identification of novel miRNA targets in the pathogenesis of hypertension is a highly valuable and exciting strategy that may eventually led to the development of novel treatment approaches for hypertension. Several mechanisms have been implicated in the pathogenesis of hypertension: overactivation of therenin-angiotensin-aldosterone system (RAAS), dysfunction of the vascular endothelium, damnification of vascular smooth muscle. To maintain and restore target organ expression of miRNA stable may be a new strategy for treatment of hypertension. The article reviews pathogenesis of miRNA and hypertension, researches of miRNAs as biomarker and therapeutic target, discusses advances in miRNA-based approaches that may be important in treating hypertension.

Objective To investigate the effects and safety of the treatment of continuous veno-venous hemofiltration (CVVH)in refractoriness heart failure with renal insufficiency patients.Methods 35 hospitalized patients of refractori- ness heart failure with renal insufficiency were chosen from 2001 to 2006,25 patients were treated by CVVH,and other 10 patients were treated by regular hemodialysis.The serum BUN,Cr,left ventricle ejection fraction(LVEF),were observed before and after the therapy in each group.Results The clinical symptom were obviously improved in Group HF,and LVEF,cardiac output(CO) were both increased by continuous hemofiltration treatment(P

BACKGROUND:Currently,there is not a standard method for in vitro culture and large scale amplification of umbilical cord blood mesenchymal stem cells(UCB-MSCs).OBJECTIVE:To investigate the isolation,purification and culture of UCB-MSCs in vitro,and to detect its surface marker variation.METHODS:The monocytes were harvested from UCB using 1.077 g/cm3 lymphocytes separating solution and density gradient centrifugation,followed by incubation in an incubator containing 5%CO2 at 37℃.The cell morphological changes were observed at different time points and the expression of surface marker was detected using flow cytometry.RESULTS AND CONCLUSION:The monocytes isolated from the UCB grew initially into numerous hematopoietic cell clones,most of which were granulocyte/macrophage colony-forming units and burst forming unit-erithroid,increasing by(37.1±2.3)and (10.4±1.7),respectively.Switzerland staining showed most of them were granulocyte clones(80,1±85.2)%,next was erythroid clones(14.2±1.8)%.At 7 days after culture,some shuttle fibroblast-like cells and fiat osteogenic-like cell spread the whole plastic well.At 14 days after culture,flow cytometry showed CD38+ cells accounted for 1.64%,and CD34+/CD38+ cells accounted for 1,71%,and CD34+/CD38- were 0.55%.PI+ and Annexin-V+ cells accounted for 0.05% and 0.18% respectively.At 21 days after culture,CD38+,CD34+/CD38+ and CD34+/CD38- cells were 74.32%,1.61%,and 0.24%.The results reveled that UCB-MSCs can be isolated and cultured in vitro.

Objective To explore the characteristics and the clinical application of MR perfusion weighted imaging(PWI)in the normal kidneys and the renal diseases.Methods Thirty-one subjects including 9 cases without urinary diseases,14 cases with renal carcinoma,6 cases with renal cyst and 2 cases witll renal tuberculosis who had been examined with T1WI,T2WI and PWI were analyzed retrospectively.All the data were processed by a workstation to obtain time-signal intensity curves,color perfusion maps and relative perfusion value.The relative renal blood volume(RBV),relative renal blood flow(RBF),mean transition time(MTT)and the time to peak(TTP)in the normal renal cortex and medulla and the renal lesions were calculated.Comparisons between the right and the left normal kidneys,and between the cortex and the medulla of the normal kidneys were performed using t test,and comparisons between the normal and the abnormal kidneys were performed using q test.Results Relative RBV and relative RBF of the cortex were 1.33±0.08 and 1.44±0.09 respectively,and for medulla were 0.58±0.05 and 0.78±0.13 respectively(t=9.2241 and 5.0336,P＜0.01);MTT(1.11±0.08)and TTP (1.04±0.06)of the cortex has no difference with that of the medulla(0.97±0.04 and 0.94±0.03)in the normal kidneys(t=2.2551 and 2.2613.P＞0.05).The values of relative RBF of the renal carcinoma (1.35±0.34)were significantly higher than that of the normal tissues(1.02±0.06)(q=3.0882,P＜0.01).Conclusion PWI is able to demonstrate the hemodynamic change of the normal renal tissues and the renal lesions,and it maybe an ideal method for showing the functional changes of the kidney and for differentiating the renal diseases.

Objective To identify the effect of health risk behaviors on accidental injury of adoles-cents.Then analyze the strength and approach of the health risk behaviors. Methods Cluster sampling on various stages and strata methods was adopted. The adolescents from grade one to three in junior school students and grade one to three in senior high school students completed the questionaire. A total of 4408 students were surveyed and 4309 samples were valid. Path analysis was used to understand how factors could influence injury incidence. Results The incidence of adolescent injury was 15.53%. Statistical differences were found between genders (male 17.77%,female 13.36%,χ2=15.91, P<0.01),education levels (junior high school 17.36%,senior high school 13.99%,χ2=11.45, P<0.01) and cities ( Beijing 12.97%,Zhongs-han 17.95%,χ2=20.33, P<0.01) . Those who got injured were found with more health risk behaviors. Health risk behavior was the direct influencing factor to injury,as well as a possible risk factor to multiple injuries. Conclusion Health risk behaviors can strongly affect adolescent injury,and can be an indicator. Reducing health risk behaviors is important in adolescent injury prevention.
