The relative risk of cardiovascular events for patients with fibrinogen >4.0 g/L and hs-CRP>3.0 mg/L was 3.84(P<0.05),95% CI(2.80 to 4.99) compared with patients with fibrinogen≤4.0 g/L and hs-CRP≤3.0 mg/L.

Objective: To investigate the changes of serum interleukin-10 and interleukin-18 before and after percutaneous coronary intervention(PCI) therapy and their correlation with cardiovascular events,for exploring the mechanism of cardiovascular events after PCI and its correlation with IL-10 and IL-18.Methods:In 70 patients performed PCI,the levels of IL-10 and IL-18 were detected before and 4 hours after therapy,the cardiovascular events were followed up 12 months after therapy.

The results of classification of ENSO events for the period from 1882 to 1997 show that there were 25 stronger EL Nino events including 13 Eastern pattern and 12 Central pattern events, and 21 stronger La Nina events, including 13 Eastern pattern and 8 Centralpattern events.

Results:The effective rate for active,controll and open group were 89.0%,80.0%,and 89.0% respectively and the incidence of adverse events for active,controll,and open group were 14.0%,16.0% and 14.0% respectively.

Based on the numbers of singly tagged D + s events for each of the three decay modes,the decay branching fractions for D + s→ K *0 K + and K 0 K + have been determined to be (3.02±0.94±0.91)% and (3.28±1.22±0.94)%,respectively.

Taking into account the reconstruction of similar Early Vendian events for many provinces elsewhere, we can suppose that Early Vendian sedimentation basins in the southern and middle Urals were connected with the World Ocean.

Our results support the idea that the development of post-eruptive loops depends on the energy of the impulsive events for the phenomenon as a whole.

In such a case, many return events for an electron must be taken into account.

The tagged photon events for the measurement of the e+e- → π+π- total cross section by the radiative return method at DAΦNE is discussed.

A Monte Carlo method with overlapping beam-monitor-triggered events for the calculation of effects caused by time coincidences of events under study and accidental activity in detectors of the NA-48 setup is developed.

This paper described the theoretical basis and practical calculation for analyzing fading records obtained by close-spaced recievers in the study of the small-scale irregularities in the ionosphere. Two new correlation methods, the cross-point method (C. P. M.) and the ten-point method (T. P. M.), were proposed and compared experimentally with Phillips and Spencer's complete correlation method (P. S. M.) and Yerg's six-point method (S. P. M.). It is concluded that the C. P. M., compared with other methods, is...

This paper described the theoretical basis and practical calculation for analyzing fading records obtained by close-spaced recievers in the study of the small-scale irregularities in the ionosphere. Two new correlation methods, the cross-point method (C. P. M.) and the ten-point method (T. P. M.), were proposed and compared experimentally with Phillips and Spencer's complete correlation method (P. S. M.) and Yerg's six-point method (S. P. M.). It is concluded that the C. P. M., compared with other methods, is more exact and provides for more information about the ionospheric irregularities. The C. P. M., as well as the P. S. M., require the determination of the auto-correlation function of one record and the cross-correlation functions between the three records taken in pairs, and it is therefore quite laborious. Then it is shown that there are some advantages in the application of the T. P. M. which provides for informations as much as that of the C. P. M. and as exact as that of the P. S. M., although the calculation is much simpler, as only 8—10 values of correlation coefficient are required. Moreover, it is pointed out that, utilizing the so called "time-lag plots" y_θ, x_θ, the accuracy of the T. P. M. can be further improved. Therefore it is suggested that the T. P. M. should be adopted as a routine, while the C. P. M. or the improved T. P. M. should be adopted for special occasions or special events for which more accurate results are required. for special occasions or special events for which more accurate results are required. In the viewpoint of labour-saving, applications of the structure function and the aftereffect function to the correlation analysis are discussed. In this paper the author also proposed an extrapolation and interpolation method of the value of correlation coefficient for any spacing and/or any time lag. Consequently, some criteria were established for checking the reliability of the calculated values of ionospheric parameters. Especially the occurrence of imaginary value of the random movement and change velocity can be almost always prevented in the course of analysis.

Percentage is one of the most common indices employed in medical research. It is not desirable to apply the general formulas for the test of significance of the difference between two pro-portions, p_1-p_2, when p_1(or q_1)=0 and N_p(or N_q)<10 implying n_1 p_1(or n_1 q_1)<5, where N is the sum of the individuals of the samples, i.e.N=n_1+n_2, and p=(n_1 p_1+n_2 P_2)/N.A problem arises, here in this paper: If there is a random sample N from a population, of which r individuals have the characteristic A,when...

For N individuals taken r at a time, the number of all the possible combinations is (); and for f individuals ta-ken r at a time, the number of all the possible combinations is ( ). Thus, the probability of the event that all the r individuals possessing A happen to fall into the subsample f is P= (Ⅰ)or P=(Ⅱ)When both N and f are large, the following sim-plified formula can be used: P≤()~r (III) Practically, when r<10 and f>10r, the value of(f/N)~r is very close to the exact value of P.This value of P is of one tail, that is to say,the 5% level of significance used for a two-tail test will be 0.025, if these formulas are emp-loyed.Ex. 1. N=100, f=23, r=2.According to (III),P<(23/100)~2=0.053.Since f=23 is larger than 10r=20, we can esti-mate that the exact value of P is very close to 0.053, in other words, that P is larger than 0.025. By (II) we know exactly P=0.051>0.025.If the general formula, T=(p_1-p_2)/), was applied, the value of P (two-tail)would be lower than 0.01, a misleading result. Ex. 2, N=250, f=140, r=8.According to (III),P<(140/250)~8=(0.56)~8.The value of n~r can be easily found in the Bar-low's Table. Thus, we get P<0.0097<0.025.When f is less than 10r, the exact value of P can be found easily according to (I) by using the table of logarithms of binomial coefficient,1g(), and the table of logarithms or antilog-arithms.Thus, this method is the simplest and also reliable one for the test of significance between a small percentage and 0%. Notwithstanding that such a problem may also be treated other-

In view of the fact that the characteristics of interplanetary shock wave near IAU depend on the durations of solar events, we have selected 146 MHZ C type outbursts that are observed at the Mi Yun Station of the Pekin Observatory, analysed the statistical relationship between c type outbursts and magnetic storms, then investigated the possibility of prediction of magnetic storms using c type outbursts.It is concluded that using such selected solar events for prediction of magnetic storms, one can get results agreeable with the Stonchoker's forecasting system that refer concurrently to Hα flares, Ⅳtype radio bursts and 200 MHZ outbursts, bat the statistical properties between solar events and magnetic storms are not congruent with that used by Stonehokei because the criteria selecting events are different.
