Cytokine-effects of soluble CD23(sCD23) were investigated in our laboratory. We found that sCD23 prepared by ourself could increase the migration inhibition effect of nomal peripheral blood leukocytes stimulated with PHA. It is proposed that sCD23 may have cytokine-like bioactivities on activated T cell and regulate immune response via an unknown mechanism.

The research to improve outcomes in critically ill patients through nutrition support has steadily progressed over the past 4 decades. One current approach to this problem is the addition of specific nutrients as primary therapy to improve host defenses and improve the outcomes of critically ill patients. The field is referred to as“pharmaconutrition”,focusing investigations on each nutrient to understand its pharma-cological effects on immune and clinical outcomes. The purpose of this review was to introduce some of the known pharmaconutrients such as glutamine,arginine,ω-3 fatty acids,vitamin C,zinc,and selenium,regard-ing critical ill adults and children.

Malnutrition is highly prevalent in hospitalized children and has been associated with rele-vant clinical outcomes.Timely nutrition risk screening and reasonable nutrition support therapy subsequently for the high risk patients is the best and standard way.Five nutrition risk screening tools have been developed to identify the nutritional risk in hospitalized children.Even though nutrition risk screening is a necessary part of standard pediatric care,there are no international standardized screening tools for pediatric inpatients so far.The near future will provide us with comparative data on teh exi sting tools which may oc ntribute to deve-loping a standard for admitted nutrti ion risk screening in pediatrics.

Objective To explore the clinical value of Holter heart rate turbulence in diagnosis of patients at high risk for coronary heart disease.Methods 110 patients with suspected coronary artery disease,according to the results of coronary angiography (CAG),were divided into CAG positive group (67 cases) and CAG negative group (43 cases).Heart rate turbulence and heart rate variability were analyzed in two groups.The atrial fibrillation,atrial flutter,and pseudo-differential interference were removed,the qualified ventricular contraction was selected.Two parameters of HRT,the initial shock value (TO) and turbulence slope value (TS) were calculated.Results The average value of TO and TS was (0.36 ± 0.15) ％,(1.98 ± 0.52) ms/RR in positive group,those in the negative group were (-0.87 ± 0.36) ％ and (4.83 ± 0.65) ms/RR,there were statistically significant differences between two groups (t =1.953,1.976,all P ＜ 0.05).After 1 year follow-up,9 cases (13.44％) died in positive group,2 cases (4.65％) died in negative group,the difference was statistically significant (x2 =5.476,P ＜ 0.05).Conclusion The heart rate turbulence with dynamic cardiogram can help to early diagnose the patients at high risk of coronary heart disease.It was important to improve the survival rate of patients.The method is simple,inexpensive,effective,which is worth promoting in the clinic.
