Objective To investigate the amlodipine or hydrochlorothiazide and valsartan combination thera-py in elderly hypertensive patients with blood pressure variability ( BPV ) and nitric oxide ( NO ) , endothelin role. Methods 552 elderly patients with hypertension were divided into the observation group and control group,276 cases in each group,the observation group was given amlodipine valsartan for treatment,while the control group was received hydrochlorothiazide combined with valsartan for treatment,the two group were treated for three months,the content of BPV,NO and plasma endothelin were analyzed.Results After treatment,the 24hSBPV,day SBPV,24hDBPV,day DBPV of the observation group significantly decreased compared with pre-treatment, the difference was statistically significant(t=20.09,15.97,9.31,9.41,all P<0.05),patients in the control group only 24hSBPV and day SBPV [(9.12 ±2.57)%,(8.43 ±1.97)%]were significantly lower than before treatment(t=12.31,9.53,all P<0.05);The day SBPV,24hDBPV,day DBPV[(7.21 ±1.34)%,(12.31 ±2.54)%,(10.59 ±2.73)%]of the ob-servation group after treatment were significantly lower than those of the control group(t=10.52,12.34,8.35,all P<0.05);The NO[ (66.12 ±23.57)%,(68.29 ±21.52)%]and endothelin levels[(34.43 ±7.97)%,(34.21 ± 7.34)%]of the two groups after treatment were significantly lower than those of before treatment(tobservation grou P=31.39,11.79,tcontrol grouP=28.31,9.35,all P<0.05).Conclusion The amlodipine or valsartan hydrochlo-rothiazide used clinically can effectively control blood pressure, significantly increase NO levels, decrease plasma endothelin levels,which is worth to be used in the clinical.

Objective To use bioinformatics methods to analyze large amounts of data generated by gene chips and to screen common key genes in hepatocellular carcinoma in human and rat.Methods For search of the medical literature,3 sets of gene chip with data which met our predetermined criteria were downloaded from the GEO database.The data were standardized by using the bioconductor and R version of the 2.10.1 version.The original data of the affymetrix platform were normalized with background correction,standardized and transformed into log2 by using the algorithm of the affy packages RMA.The TTEST function of the excel was then used to calculate the significance of each gene.The DAVID was used for gene ID conversion and a table was established for samples and the corresponding gene expression data.A meta analysis was performed to calculate the common genes of human and rat.An enrichment regulation pathway was gained with the KEGG in the DAVID library. Results There were 26 common expression genes in the development process of hepatocellular carcinoma in human and rat.Five of these genes were up-regulation genes,while twenty-one were down-regulation genes.An enrichment pathway,which is a focal adhesion pathway,was found and this pathway has been reported to be associated with development of hepatocellular carcinoma.Conclusion With bioinformatics,we were able to screen common key genes and a pathway which were closely related to development of hepatocellular carcinoma in human and rat.

Objective:To explore the association between CYP2D6 gene polymorphism of cytochrome and clinical response to atomoxetinein children with attention-deficit/hyperactivity disorder.Methods:Totally 111 Han Chinese boys meeting criteria for ADHD in the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edi-tion (DSM-IV)were recruited.Atomoxetine treatment was given in titrated doses in order to achieve optimal re-sponse.Behavior changes were measured with the ADHD Rating Scale (ADHD-RS)at baseline and after optimal doses were reached.The decrease of ADHD-RS scores were primary measures of the treatment effect,the scores of the items in the ADHD-RS was less than or equal to 1 for the remission criteria.The three SNPs of CYP2D6 genes(rs1080985,rs1065852,rs16947)were genotyped by polymerase chain reaction (PCR).Results:There was no asso-ciation between single polymorphisms andatomoxetine after adjusting for baseline rating scores (P >0.05).In con-trast,haplotype analysis revealed that some patients with GAC haplotype achieved significant remission [remission vs.non-remission haplotype frequency (rate):5 /56 (8.9%)vs.3 /164(1.8%),P <0.05 ].After multiple testing correction still existed significant trend(P =0.082)and also found correlation trends after correlation analysis be-tween GAC haplotype and clinical response to atomoxetine (P =0.078),8 patients with GAC haplotype carriers were all effective response to treatment,non-responders without this haplotype.Conclusion:These results suggest association between polymorphisms of CYP2D6 gene and ADHD better clinical improvement with atomoxetine treatment,it is worth further exploration in a large sample.

Based on the reconstruction of two-dimension phase space of time series of short ECG signals, the variation of the strange attractor geometry is described and two indices, VMI and VAI, are derived in this paper. The two indices can distinguish clearly the ECG signals of sinus rhythm, tachycardia and ventricular fibrillation. Stable results of VMI and VAI can be obtained by analyzing ECG signals of several seconds. They are expected to be used in the development of medical instruments for a fast realtime display of analysis results.
