Purpose To evaluate the value of imaging on the diagnosis and treatment of human-infected H10N8 virus. Materials and Methods The chest X-ray and CT features of one case of human infected H10N8 virus were retrospectively studied. Results A 73-year-old female patient was admitted to the third affiliated hospital of Nanchang University on November 30, 2013 due to cough, sputum for 3 days and fever for 1 day. The patient was diagnosed with severe pulmonary infection and underwent chest CT on December 1, which showed large opacities with air bronchograms were in the lower lobe of her right lung and ground-glass exudative lesions in the lower lobe of the left lung;the next 24 h, 48 h and 72 h review tracking chest X-ray showed the chest lesions developed rapidly which involved more lobes with more areas, integration of lesions and plenty of pleural effusion in a very short time. This was a typical white lung sign of acute respiratory distress syndrome. The patient died later on December 6, which was reported as the case of human-infected avian influenza (H10N8 virus) by Chinese Center for Disease Control and Prevention. Conclusion The chest imaging features found in human infected H10N8 virus present as progressive opacities and exudative lesions.

Objective To investigate the clinical value of low-dose decitabine (DAC) in elderly patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) patients with intermediate-or high-risk. Methods Low-dose DAC (10 mg/d, 7 days) combined with CAG regimen were given to 19 elderly patients with AML and intermediate- or high-risk MDS patients. The efficacy and adverse reactions were evaluated after a course of treatment, and the patients were followed up for survival. Results After a course of treatment, 8 patients achieved complete remission (CR), 7 patients achieved partial remission (PR). After 4 courses of treatment, 68.4 % (13/19) of patients achieved CR, the overall response rate reached 78.9% (15/19). Fewer side effects were seen associated with chemotherapy. After 42 months of follow-up, there were 12 survival cases, the median survival time was 13.5 months (3-42 months). Conclusion Low-dose DAC combined with CAG regimen have a better efficacy, higher safety, and lower economic burden for elderly AML patients and intermediate- or high-risk MDS patients, which is beneficial to greatly improve patients' compliance.

The DNA fragment sized 2 139bp, the same Sequence with AtKup1 gene from Arabidopsis thalianna was used as the templates for DNA family shuffling. The shuffeld AtKup1 gene library was expressed in the mutant of 5. cerevisae in which potassium transporter gene TRK1 and TRK2 were knocked out by homologous recombination. Then the screening was carried out in the low potassium media containing 5. 0 mmol/L KC1 and no histidine in it. it was found that both of diverse and wild AtKup1 gene can rescues the trk1△trk2△yeast mutant strain in low [ K + ] medium. The growth of 2 clones yeast containing diverse AtKup1 were beter than that of AtKup1 wild gene transformant. The sequencig results of the shuffeld AtKup1 showed that there were 2 nucleotide changed, which resulted in 2 amino acid variations in it compared with the original AtKup1. The potassium uptaking capacity of shuffled AtKup1 gene increased significantly when it was transformed into tobacco.

A method for the determination of S-Adenosyl-L-methionine in fermentation liquid using the high performance liquid chromatography coupled with UV detector (HPLC-UV) was developed.A good linearity was obtained in the range of 0.1～1.0g/L (r = 0.9969) for S-Adenosyl-L-methionine.The average recoveries of S-Adenosyl-L-methionine were 99.89%～101.7% and the relative standard deviations were 0.48%～1.36%.The method is simple and rapid with reproducibility for the determination of S-Adenosyl-L-methionine in ferment liquid.

Objective To investigate the relationship between psychological quality and performance capacity of the crew in armored equipment so as to provide scientific evidence for the training of crew .Methods The psychological quality of 82 crew members of armored cavalry was tested and analyzed by neurobehavioral testers and questionnaires .Results and Conclusion The education level and age had no significant effect on the performance capacity among the armored crew . The test results of psychological quality parameters showed the same trend as the performance capacity of the crew , but their psychological health status had obvious effect on the performance capacity .The psychological quality of the crew had great influence on their performance capacity ,so we should pay attention to mental intervention ,enhance psychological protection ability of the crew , and improve their combat effectiveness continuously .

Objective To investigate the efficacy and safety of catheter radiofrequency ablation of paroxysmal supraventricular tachycardia.Methods From Jul 2003 to Jan 2011,1106 cases with narrow QRS complex tachycardia who were treated by catheter radiofrequency ablation were recruited from our center and followed up for the rates of successful treatment,rcurrence and complications.Results There were in total 1106 patients (atrioventricular reentrant tachycardia:588 ; atrioventricular nodal reentrant tachycardia:477; atrial tachycardia:41 ),with a sex proportion of 1∶1.Successful ablation rate was 98.3 ％ (1087/1106).Of the 1087 successful ablation cases,43 (3.9％ )were warranted repeated ablation.The recurrent rates for trioventricular nodal reentrant tachycardia,atrioventricular reentrant tachycardia,left accessory pathway and right accessory pathway were 1.5％,5.6％,3.9％,and 9.1％ respectively.Complication rate was 1.5％.The major complications included pheumothorax ( 6 cases ),pulmonary embolism ( 1 case ),transient third-degree atrioventricular block ( 2 cases ),first-degree atrioventricular block ( 3 cases ),and persistent third-degree atrioventricular block(2 cases)with pacemaker implantation.There was one case of cardiogenic sudden death 5 days after the treatment procedure.The cause of his death was chronic stroke-related but not related to the operation procedure.Conclusion Catheter ablation has high efficacy and low complication rate in long-term follow-up,and is a promising treatment for paroxysmal supraventricular tachycardia.

Objective To investigate the effects of early rehabilitative training program on patients with acute myocardial infarction(AMI).Methods One hundred and twenty-two patients with AMI were randomly divided into early rehabilitation group(n=62)and control group(n=60).In addition to routine treatment,patients in rehabilitation group received early rehabilitative training mainly by walking exercise for two weeks.Results There were no significant differences in ventricular arrhythmia(Lown≥Ⅲ), extension of infarction and heart rate variability(HRV)between the two groups(P＞0.05).Forty of 62 patients(64.5%)in rehabilitation group had their left ventricular ejection fraction(LVEF)more than or equal to 50% in the 3~(rd)～4~(th)week after admission,significantly higher than that in control group(45.0%, 27/60 ;P＜0.01 ).By the end of the 4~(th)week after admission,25.8% of the patients in rehabilitation group showed positive in treadmill test,significantly lower than that in control group(38.3%,P＜0.01). Occurrence of angina pectoris and reinfarction and fatality in rehabilitation group were significantly lower than those in control group(P＜0.05)during their hospitalization and follow-up period.Patients in rehabilitation group stayed at hospital for(16?3)days in average,significantly less than that in control group[(27?4) days],with statistically significant difference(P＜0.05).Conclusion Early rehabilitative training for patients with uncomplicated AMI is not only safe and feasible,but also useful in improvement for their prognosis and quality of life.
