Effect of hemoperfusion cartridge on different internal environmental indicators

BACKGROUND:This study aimed to observe the effect of hemoperfusion(HP) cartridge on different internal environment indicators at different time points in patients with acute blood poisoning and to find alternative indicators for the detection of blood poisoning.METHODS:The levels of internal environment indicators(blood pH,P_vCO_2,P_vCO_2,blood lactate,potassium,free calcium,bicarbonate,and blood glucose) before and after HP treatment were recorded for patients with acute poisoning at time points of 30 minutes and 120 minutes.After calculating the difference value 5,the statistical software was used to analyze the statistical difference of the influence caused by HP cartridge at two time points.According to the formula,adsorption rate%=(a-v)/a×100,the adsorption rate of each indicator was calculated respectively.RESULTS:The difference of indicators at different time points in inlet and outlet such as blood glucose,free-calcium,and lactate was statistically significant(P<0.05),but the difference in indicators such as pH,P_vCO_2,P_vO_2,potassium,sodium,and bicarbonate was not statistically significant(P>0.05).CONCLUSION:During HP treatment,the indicators of blood glucose,free-calcium and lactate were significantly affected by HP cartridge,and the effect varies with time.

Assessment of China's International Environment and U.S. Strategic Trend

It is of great significance to have a clear understanding of the international environment that China faces. But this is an uneasy job. Since September 11, the world situation has become so complicated that it is hard to grasp its essence even with painstaking efforts. To judge such an already complicated international environment from China’s perspective adds more difficulties, for different people usually have different views due to the different angles from which they see the situation and different methods they adopt. This, understandably, leads to hot debates within the Chinese academic circles. To provide a stage for exchange of views, at the invitation of the CIR Expert Forum, some well-known scholars and experts on international relations from Beijing gathered to hold a symposium on November 5, 2002, with the theme of "How to assess the international environment that China faces". The speeches at the symposium will be published in two installments. Following are the first half.

THE INTERNATIONAL ENVIRONMENT AND OUR FOREIGN POLICY

After the bombing of our embassy in Belgrade, Chinese students of internationalrelations tensely discussed about China’s international environment. The manyopinions fell into two basic groups. One expressed the belief that the war in Kosovobrought about a fundamental change of the international environment; the othergroup thought that the Kosovo War merely reflected the post-Cold War interna-tional reality rather than changing the international environment. In order to cor-

Assessment on the Two New Factors That Influence China's International Environment

The development and changes in international situation after September 11 have exerted complicated influence on China’s external security environment. Therefore, how to judge current international security environment that China faces has become a very hot subject for discussion.

PROPAGATION OF INTERNAL INERTIO-GRAVITY WAVE SPECTRA IN VERTICAL WIND SHEAR ENVIRONMENTS

The variation of the spectral structure of the internal inertio-gravity waves (ⅡGWs) propagating in the atmospheric wind shear environments is discussed in this paper. From the hydrodynamic equation set in Boussinesq approximation, a spectral propagation equation ⅡGWs satisfy is derived, then the spectral correspondence in the upper atmosphere is numerically calculated, after a forced spectrum is given as a Van- Zandt one at the lower boundary. The results show that if ⅡGWs do not encounter the critical-layer absorp- tion, then their spectral structure may be not changed significantly; otherwise it may be changed greatly, and a few of spectral components are filtered. Also the isotropy of the assumed VanZandt spectrum is distorted in upward-propagating process. That is the directional filtering effect of the atmospheric wind on the gravity wave spectrum.

Create an International Environment for the Peaceful and Steady Development to Boost the Sound Development of Human Rights on the International Stage——An Address at the Opening Ceremony of the 7th Beijing Forum on Human Rights, Spet. 17, 2014

Since its initiation in 2008, the Beijing Forum on Human Rights has been bent on promoting our mutual understanding and expanding our common grounds. It has carried out very fruitful exchanges and researches around many important questions concerning human rights development, and hence attained great achievements. It has played avery constructive role in promoting exchanges about and cooperation in human rights between China and other countries, becoming an important and influential platform for international dialogs over human rights.
