Objective To evaluate the influence of empowerment education on self-management ability and self-efficacy of patients with coronary heart disease (CHD).Methods 190 patients with CHD were randomly divided into the experimental group and the control group.And all patients were trained respectively according to corresponding health education plan of each group by professional worker.These patients filled out the Essential Information Questionnaire (EIQ),Self-Efficacy Integration Scale (SEIS) and Coronary Artery Disease Self-management Scale(CSMS) at baseline,3 months and 6 months after health education.The clinical indexes in two groups such as body mass index,waistline,blood pressure,blood glucose and blood lipid were contrasted.Results The score of self-management ability and the score of self-efficacy in the experimental group was significantly more than that of the control group in 3 months and 6 months after health education,and this difference between two groups still persisted 6 months after health education.However,the score of symptom-maintaining in the SEIS and self-management of addiction,emergency,lifestyle and knowledge of diseases in the CSMS appeared to drop in the control group.Conclusions Empowerment education can significantly improve and increase the self-management ability and self-efficacy of patients with CHD,and this function of empowerment education was proved more enduring than that of traditional health education.So,empowerment education will be a new style of health education in the new model of clinical medicine instead of traditional health education.

Objective To study the relationship between the expression of mtrF gene and high-level multiple resistant Neisseria gonorrhoea.Methods ① The susceptibility of 58 clinical Neisseria gonorrhoeae to 5 kinds of antibiotic agents was tested by disc diffusion method.② The minimum inhibitory concentration(MIC) of erythromycin was determined by tube dilution method.③ The expression of mtrD and mtrF gene in susceptive group,inter-mediated resistant group and high-level multiple resistant group was detected by semi-quantitative RT-PCR.Results ① There were 30 strains presenting resistance to two or more than two antimicrobial agents,which accounted for 51.7% of the 58 clinical strains.② The number of strains sensitive,intermediate and resistant to erythromycin was 7,21 and 30,respectively,and there were 17 strains with erythromycin MIC≥32.0 ?g /mL.③ Compared with that in susceptive group and inter-mediated resistant group,mtrF expression was up-regulated in high-level multiple resistant group(P

A persistent infection model was established after human hepatoma cells infected by Japanese encephalitis viruses were subcultured for several times. Viral titers of mutant viruses in persistently infected cells were examined by plaque methods using BHK cells. Nucleotides of the E coding region of two wild and two mutant viruses were amplified by RT-PCR. PCR products were sequenced by ABI-PRSM 310 sequencing system. Compared to JaGAr-01 wild strains, four amino acids were replaced (E61Tyr --> Asp, E219His --> Tyr, E384Val --> Glu, E418Pro --> Ala) in the E sequence of JaGAr-01 persistently-infected mutant strains. Eleven amino acid replacement (E51Arg --> Ser, E61Tyr --> Asp, E83Lys --> Glu, E123Ser --> Arg, E209Arg --> Lys, E227Pro --> Ser, E276Asp --> Ser, E290Arg --> Lys, E387Lys --> Arg, E418Leu --> Pro, E454Arg --> Gly) was also noted when we compared the E sequence between persistently infected Nakayama and its wild strains. A lot of similarities of amino acid sequence between mutant strains JaGAr-01 and Nakayama were also noted. It was concluded that geno-variation existed in E region of mutant viruses and the mutant protein encoded by E region, especially the mutation of E61 (Tyr --> Asp) may contribute to the maintenance of the persistent infection of Japanese encephalitis virus.

Objective To explore the changs of serum brain type creatine kinase isoenzyme(CK-BB),cystatin C of newborns with hypoxic-ischemic encephalopathy(HIE) and assess their applications.Methods The serum concentrations of CK-BB and cystatin C were measured by turbidimertric immunoassay in 56 HIE newborns and 42 normal neonates.Results 1.Compared with controls,the concentration of serum CK-BB in moderate HIE newborns had significant differences(P

The value of combined application of both ECG-gated cine MRA and 3D-CEMRA in the detection of large intracranial aneurysms was evaluated and the findings were compared with those of conventional MRA and DSA. Twenty-four patients with 26 large intracranial aneurysms underwent MRI and DSA. All these aneurysms, diameter from 15 to 39 mm, were located at internal cerebral artery (n=12), vertebral artery (n=3), basilar artery (n=4), anterior cerebral artery (n=2), middle cerebral artery (n=2), anterior communicate artery (n=2) and posterior communicate artery (n=1). Thirteen cases of hematoma or cavernoma were studied as control group. All patients were examined on GE 1.5T MR system. ECG-gated cine MRA was performed with 2D multi-phase fast gradient-recalled echo sequence in a single section. All the images were analyzed with signal intensity VS time curve for differentiating intraaneurysmal blood flow from static tissue. The results were analyzed by statistic "t" test. 3D-CEMRA was performed with spoiled gradient-recalled echo and one dose of Gd-DTPA. All data was processed with multi-plannar reformat (MPR) and tomography for the demonstration of aneurysms in detail. All 26 aneurysms were demonstrated successfully by combined application of both cine MRA and 3D-CEMRA. Compared to DSA and conventional 3D-MOTSA, its sensitivity and specificity figures were both 100%. Cine MRA could differentiate the blood flow from the static tissue. The intensity VS time curves of intraaneurysmal blood flow offered fluctuating form and average signal change between systole and diastole period was about 89.8 +/- 37.4; However, under the control group, intraaneurysmal thrombus or cerebral hemorrhage or cavernomas had no significant signal change and the curves offered steady form with the average signal change being about 8.2 +/- 6.3. There was statistically significant difference between the intraaneurysmal blood flow and static tissue (P=0.025, <0.05). 3D-CEMRA was very useful in demonstrating the aneurysmal size, intraaneurysmal thrombus formation, neck and the detailed relationship of the aneurysm to the surrounding structures. It was concluded that the combined application of both cine MRA and 3D-CEMRA might be a valuable clinical tool for the detection of large intracranial aneurysms.

Objective:To establish a glioma cell line U251 stably expressing programmed cell death 4(PDCD4)gene,and to observe the influence of exogenous PDCD4 gene on the proliferation and cell cycle of U251 cells.Methods:Recombinant eukaryotic expression vector pEGFP-PDCD4 was transfected into human glioma cell line U251 by Lipofectamine 2000,and the U251 cells stably expressing PDCD4 were established by G418 selection.Reverse transcription polymerase chain reaction(RT-PCR)and Western blotting were employed to detect the expression of PDCD4 mRNA and protein.Furthermore,cell proliferation and colony forming ability were determined by cell counting and colony formation assay;the cell cycle was detected by FACS.Results:High expression of PDCD4 mRNA and protein was observed in U251 cells transfected with pEGFP-PDCD4,whereas no PDCD4 mRNA and protein expression was detected in the non-transfected and vector-transfected cells.Further,cells transfected with pEGFP-PDCD4 grew more slowly and had lower colony formation rate than cells of the other two control groups(P

As a kind of additive in feed of monogastric animals, the application of natural phytase is limited due to its disadvantages. In this paper, the strategies of phytse reform was introduced. Furthermore, the research and progress on protein engineering of feed phytase was reviewed, including phytase over-expression, phytase thermostability, catalytic efficiency and optimum pH.
