ObjectiveTo evaluate the effect of lifestyle intervention on high-risk individuals for hypertension. MethodsOne hundred and four prehypertensive adults who received physical examination during October 2005 and October 2007 and showed at least 2 hypertension risk factors were randomly assigned to the experimental or control group.A muhicomponent behavioral intervention,including health education(e.g.awareness of disease),metary gmdance,physical.exercise,and psychologtcat improvement,Was conducted for 2 years.The awareness of disease,blood pressure,bedy weight,and the change of risk factors were compared.ResultsAt 2 years,the awareness of disease in the experimental group wag significantly improved,and the blood pressure,body weight,and risk factors were obviously reduced.Although the awareness of disease and the risk factors in the control group were improved,the blood pressure and body weight were increased.The difference in average systolic blood pressure,average diastolic blood pressure,body weight,and the awareness of disease between the two groups were 13 mm Hg(1 mm Hg=0.133 kPa),7.9 nlnl Hg,3.7 kg,and 37.6%,respectively(all P<0.05).ConclusionThe lifestyle intervention among high-risk individuals for hypertension could effectively reduce blood pressure and body weight. Improved lifestyle would result in less risk factors.

AIM To study the effect of TNP 470 on proliferation, cell cycle and apoptosis in the cultured human colon cancer Lovo cells. METHODS The growth inhibition of TNP 470 on Lovo cells was evaluated by an MTT.assay The effect of TNP 470 on cell cycle and apoptosis measured by flow cytometry, and ultrastructural feature of Lovo cells were observed with electromicroscope. RESULTS TNP 470 inhibited the growth of Lovo cells. flow cytometry analysis showed that G 0/G 1 phase rate was increased but S phase rate was decreased. Apoptosis rate of TNP 470 treated group was significant high than that of control and typical chang of apoptosis in Lovo cells was observed. CONCLUSION TNP 470 can inhibit proliferation of Lovo cells, and this inhibition is associated with cell cycle block and apoptosis.

Objective To investigate effect serum Bcl-2 and Bax in patients with myoma of uterus by Jiang Sanqi.Methods 92 patients with uterine fibroids were selected,and randomly divided into experiment group and control group.Control group of 46 cases treated with goserelin once 3.6 mg every month,subcutaneous injection,mifepristone 12.5 mg,once a day for oral treatment.Experiment group of 46 cases treated with Jiang Sanqi,0.5 g/kg,once a day for boiling water, for 3 months.The level of Bcl-2 and Bax in serum, clinical efficiency, diameter of tumor and complications were compared after treatment.Results The levels of Bcl-2 of experimental group patients was lower than control group, the level of Bax was higher than that of the control group (P<0.05).The total efficiency of experimental group(89.13%)was higher than that of the control group(71.74)%(P<0.05). The experimental group tumor diameter was smaller than the control group(P<0.05).Complications of the experiment was lower than the control group (P<0.05).Conclusion Jiang Sanqi can significantly reduce the serum Bcl-2 of patients with uterine fibroids,increase the expression level of Bax, reduce the uterine fibroids diameter effect, reduce the incidence rate of hormone suppression of drug side effects, has a great significance in clinical.

Objective To investigate the effect of Yiqihuayu herb on serum NF-κB p65 and myocardin in patients with hysteromyoma. Methods 56 cases patients with hysteromyoma were selected and divided into two groups.The control group of 28 cases were treated with mifepristone, and the experiment group of 28 cases were treated with Yiqihuayu herb.The clinical curative effect, uterine myoma volume, expression of NF-κB p65 and myocardin level were compared after treatment.Results The clinical curative effect of the experiment group was 89.29%, which was higher than 67.86% of control group(χ2 =3.82,P<0.05).Compared with control group, NF-κB p65 expression level was lower(P<0.05), myocardin expression level was higher ( P<0.05 ) , the volume of uterus and uterine myoma were smaller ( P<0.05 ) .Conclusion Yiqihuayu recipe could reduce the expression of NF-κB p65 in serum, increase myocardin level, and reduce the volume of uterus and myoma, which has good clinical curative effect in the treatment of patients with hysteromyoma.

In this paper, an improved empirical mode decomposition (EMD) algorithm for phonocardiogram (PCG) signal de-noising is proposed. Based on PCG signal processing theory, the S1/S2 components can be extracted by combining the improved EMD-Wavelet algorithm and Shannon energy envelope algorithm. Firstly, by applying EMD-Wavelet algorithm for pre-processing, the PCG signal was well filtered. Then, the filtered PCG signal was saved and applied in the following processing steps. Secondly, time domain features, frequency domain features and energy envelope of the each intrinsic mode function's (IMF) were computed. Based on the time frequency domain features of PCG's IMF components which were extracted from the EMD algorithm and energy envelope of the PCG, the S1/S2 components were pinpointed accurately. Meanwhile, a detecting fixed method, which was based on the time domain processing, was proposed to amend the detection results. Finally, to test the performance of the algorithm proposed in this paper, a series of experiments was contrived. The experiments with thirty samples were tested for validating the effectiveness of the new method. Results of test experiments revealed that the accuracy for recognizing S1/S2 components was as high as 99.75%. Comparing the results of the method proposed in this paper with those of traditional algorithm, the detection accuracy was increased by 5.56%. The detection results showed that the algorithm described in this paper was effective and accurate. The work described in this paper will be utilized in the further studying on identity recognition.

Objective:T explore the longitudinal mediation of emotional labor and emotion regulation between occupational stress and job burnout in cinema employees.Methods:This study was a two-point longitudinal study (Interval of 2 months) with the 1067 employees from 44 city cinemas across the country as the sample,using the Emotional Labor Questionnaire (ELQ) to measure the degree of emotional labor,Emotion Regulation Questionnaire (ERQ) to measure the degree of emotion regulation,Occupational Stress Indicator-2(OSI-2) to measure the degree of occupational stress,Maslach Burnout Inventory(MBI) to measure the degree of job burnout and Job Satisfaction Scale to measure the degree of job satisfaction.A series of structural equation model analyses was conducted for data analyses.Results:The scores of expression suppression were negatively correlated with scores of occupational stress (r =-0.16,P ＜0.01),and positively correlated with the scores of job satisfaction (r =0.17,P ＜0.01).The structural equation model which include the scores of occupational stress as the predictive variable,the scores of emotional labor and emotion regulation as the mediator,the scores of job burnout and job satisfaction as the outcome variable fit well.Emotional labor (surface acting and deep acting) acted as a mediator between occupational stress and job burnout(95 ％ CI:0.03-0.05;0.02-0.05).Emotion regulation (cognitive reappraisal) acted as a mediator between occupational stress and job bumout(95％ CI:0.01-0.03).Conclusion:Emotional labor and emotion regulation acted as a mediator between occupational stress and occupational outcomes.Expression suppression has positive effect in Chinese culture.People who well in using cognitive reappraisal can lead to positive work effect througgh more deep acting and less surface acting.

Objective: To develop a computer game addiction inventory (CGAI) for Chinese college students. Methods:A primary inventory made by the authors was applied to 477 college students from 8 universities in Beijing for exploratory factor analysis, and then to 405 college students for confirmatory factor analysis. Results: After exploratory factor analysis, a questionnaire consisted of 33 items were established, which had four factors: dependence and addict behavior, emotion arousal, functional impairment, and shame and un-satisfaction. These four factors could explain 55.1 of the total variance, were confirmed by confirmatory factor analysis (?~2/df=2.304; IFI=0.885; CFI=0.884; NFI=0.813; RSMEA=0.057). The internal consistency of the questionnaire was good (r=0.77~0.94), the test-retest reliability was 0.907. Criteria validity shown by higher scores in addiction group than normal control was also satisfying. Conclusion: The CGAI has good psychometric features and could be applied to college students.
