Objective:To observe the characteristics of 24 hour ambulatory electrocardiogram in patients with chronic atrial fibrillation (AF) and optimal ventricular rate control. 　　Methods:Holter monitoring was performed in 122 hospitalized patients,aged 17—85 (mean 51.57±11.94) years,with organic heart disease and chronic AF (New York Heart Association functional class Ⅱ-Ⅲ) in whom the ventricular rate were well-controlled by digoxin.Maximum,minimum and mean ventricular rates,the number of ventricular pauses of ＞1.5 second,and the longest ventricular pauses during the monitoring were recorded.Follow-up data were collected in 72 patients. 　　Results:The mean,fastest and lowest ventricular rates over 24 hours were 78.53±8.12(65—90)，143.79±28.85(90-183) and 51.04±7.52(34—71) bpm,respectively.Bradycardia of less than 50 and 45 bpm occurred in 62 and 32 of the 122 patients,respectively.Ventricular pauses of more than 1.5 and 3.0 seconds were noted in 95 and 14 of the 122 patients,respectively.The longest ventricular pause was 2.38±0.55(4.64—1.60) seconds.During follow-up,there were no worsening in these patients. 　　Conclusion:Ventricular pauses at rest and nocturnal bradycardia were common in patients with chronic atrial fibrillation who had ventricular rates controlled.The dosage of digoxin should not be changed,nor pacemaker insertion is needed.

Objective To genotype Yersinia pestis and explore intrinsic relationship among different ecotypes of Yersinia pestis in Yunnan foci.Methods A total of 171 strains from three types of Yersinia pestis,house mouse,wild-type mouse and Yulong Yersinia pestis,were tested.Twenty-three different regions (DFR) were used to genotype and cluster analysis was performed using BioNumerics 5.0.Results A total of 171 Yersinia pestis were divided into 7 genotypes by 23 DFRs,which were Genomovar5,Genomovar7,Genomovar9 and 4 newly discovered genotypes.The genotypes of all Yulong plague were Genomovar5.The genotypes of the 16 strains of wild-type mouse plague (the highland of northwestern Yunnan Province type) were divided to 3 genotypes,13 of them were Genomovar 7,2 of them were Genomovar9,and 1 of them was newly discovered genotype Genomovaryn1.The genotypes of the 148 strains of house mouse plague(the residential area of Yunnan and Fujian Provinces type) were divided into 4 genotypes,145 of them were Genomovar9,and 3 of them were newly discovered including Genomovar-yn2,-yn3 and-yn4.The ecological typing results of clustering showed genotype of Yulong plague was similar to the highland of northwestern Yunnan Province type(wild-type mouse plague),and the percentage of similarity was up to 87.20％,but only up to 73.75％ to the residential area of Yunnan and Fujian Provinces type (house mouse plague).The genotypes of 2 wild-type strains of the highland of northwestern Yunnan Province type(wild-type mouse) and main genotypes of the residential area of Yunnan and Fujian Provinces type(house mouse)were Genomovar 9.The genotype of Genomovar-yn 1 of the highland of northwestern Yunnan Province type was similar to Genomovar 7,but lack of DFR 11.The genotypes of Genomovar-yn2,-yn3 and-yn4 of the residential area of Yunnan and Fujian Provinces type were similar to Genomovar 9,but lack of DFR 10,DFR 9 and DFR 11,respectively.Conclusions One newly genotype strain is found in wild-type mouse plague and 3 newly genotype strains are founded in house mouse plague.Wild-type mouse strains are founded in the house mouse strains.The similarity of genotype between Yulong plague and the highland of northwestern Yunnan Province type (wild-type mouse plague) is high while the similarity between Yulong plague and the residential area of Yunnan and Fujian Provinces type(house mouse plague) is low.

Interim fluorine 1 8 fluorodeoxyglucose (1 8 F-FDG)positron emission tomography (PET) integrated with computed tomography (CT) provides both metabolic and morphologic information,which becomes one of the most sensitive tools to evaluate the efficacy of the therapy and predict the prognosis of patients with lymphoma.Meanwhile,it is the basis for guiding trial design and changing clinical practice.How-ever,it is still a controversial issue in the ideal utilization of interim 1 8 F-FDG PET-CT imaging for the patients with lymphoma.

The fused gene (PTH-HSA) of parathyroid hormone (PTH) gene and Human Serum Albumin(HSA) gene was amplified without linker by Overlapping PCR technology. The spliced gene was clone into Pichia pastoris secretory vector pPIC9K. With the help of promoter AOX1 and mat ? signal peptide, the PTH-HSA gene was designed to secretory expression.Linearized by restriction enzyme SalI, The recombinant plasmid pPIC9K/PTH-HSA was transformed into Pichia pastoris KM71 by electroporation. The recombinant strains which were identified by G418 and PCR analysis were induced by methanol to express protein PTH-HSA. The target protein was expressed in fermentation supernatant. Western blot analysis of the fusion protein showed that the expressed fusion protein PTH-HSA had the antigenicity of HSA.adenylate cyclase assay proved that the fused protein exhibited the bioactivity to stimulate cAMP synthesis The specific activity of broth was about 318IU/ml.
