Evaluation of cilazapril in vasovagal syncope treatment

Objective: to evaluate cilazapril in vasovagal syncope treatment. Method: eighty\|six cases of VVS patients found positive in TTT tilt were medicated with 2.5 mg cilazapril daily for three months and followed up by TTT. Results: seven cases quit due to cough or unexplained reason; 79 VVS patients had no more fainting spells; 75.95% of TTT results of patients changed to negative after 3 months therapy. The before and after cilazapril treatment average blood pressures (taken in lying position) were 121/73 mm Hg (1 mm Hg= 0.133kPa) and 120/76 mm Hg respectively ( P > 0.05); and mean heart rates were 68.63±12.37/min and 70.13±13.15/min respectively with no significant changes ( P > 0.05). Conclusion: Cilazapril was effective in treatment of VVS; did not affect normal blood pressure and heart rate; was safe; and had little side effect.

Assessment of Heart Rate Variability and Heart Rate Turbulence Parameters in the Patients with Arterial Hypertension of the II Degree

Background： AH （Arterial hypertension） due to the extremely high incidence is the most important risk factor for development of myocardial infarctions, strokes and lethal outcomes. It is very important to identify a group of patients with increased risk of adverse outcomes to modify treatment and prevention. Significant assistance in resolving this problem is to provide a method of HM （Holter monitoring） which allows estimating the HRV （heart rate variability） and HRT （heart rate turbulence） parameters that are independent risk predictors of sudden cardiac death. The aim of our study was to assess HRV and HRT parameters in patients with AH of the II degree. Materials and methods： We have studied parameters of HRV and HRT in 214 patients with AH of the II-nd degree aged 35 to 70 （57.7 ± 7.6） years： 121 women （56.5%） and 93 men （43.5%）. All patients underwent electrocardiography and echocardiography. Statistical analysis of the results has been made using the analytical package Statistics 10.0. Results： The parameters of HRV and HRT in patients with AH of the II degree were studied. Statistically significant correlations of the HRV parameters with the age of patients, average HR, circadian index, and EF （ejection fraction） were revealed. Statistically significant correlations of the HRT parameters with the LVMI （left ventricular mass index）, EF, HR average were received. High level of the statistical significance of the interrelation of HRT parameters （TO and TS） has been revealed. Conclusions： The received results can be used during the selection of the group of patients with AH having high risk for unfavorable outcomes. Taking into account the features of the HRV and turbulence parameters and factors associated with them this will enable the individualization of the assessment of the risk in AH as much as possible and prescription of adequate treatment for each patient.

PSYCHOLOGICAL EVALUATION OF COLOR DESIGN

In this paper, a method of predicting psychological values of color design was performed by using random color patterns. The results were analyzed in terms of the Fourier transform of the color patterns, and it was found that the psychological values of the random color patterns depended not only on the zero frequency component but also on the dynamic components of the Fourier transform of the patterns. The application of the estimation method was discussed.

Western North Pacific Tropical Cyclone Intensity Guidance Evaluations Using an Alternative Verification Technique

In this study,six intensity forecast guidance techniques from the East China Regional Meteorological Center are verified for the 2008 and 2009 typhoon seasons through an alternative forecast verification technique.This technique is used to verify intensity forecasts if those forecasts call for a typhoon to dissipate or if the real typhoon dissipates.Using a contingency table,skill scores,chance,and probabilities are computed.It is shown that the skill of the six tropical cyclone intensity guidance techniques was highest for the 12-h forecasts,while the lowest skill of all the six models did not occur in 72-h forecasting.For both the 2008 and 2009 seasons,the average probabilities of the forecast intensity having a small error(6 m s-1) tended to decrease steadily.Some of the intensity forecasts had small skill scores,but the associated probabilities of the forecast intensity errors > 15 m s-1 were not the highest.

Detrended Fluctuation Analysis of Heart Rate and SaO_2 in Hypoxia

Detrended fluctuation analysis （DFA） is fit for studies on the long-range exponential correlation of non-stationary time serial. In this paper, in order to find a hy- poxia adaptability evaluation criterion, the heart rate and SaO2 signals are analyzed by this method. The demarcate exponent about fit-good-group and fit-bad-group in hy- poxia and normal air are calculated and compared. The result shows a is different in different situation, the α in hypoxia is much higher than α of breath in normal air. And α of fit-good-group is higher than fit-bad-group. It shows that DFA could be a good criterion to analyze hypoxia adaptability, which is useful in the analysis of hypoxia phys- iology signal.
