Journal of Medical Research 2006;0(12):-
Objective To explore the levels of T lymphocyte subsets in asthmatic children and discuss their relationship.Methods 30 children with acute asthma attacks were divided ito disease control(bronchopneumonias)group(25 cases)and healthy control group(14 cases).Flow cytomerty was used to analyze the T lymphocyte subsets in them.Results CD 4+ and CD 4+/CD 8+T cell of the patients of the maderate to serere degree were both significantly higher than those in normal control.Conclusion(1)CD 4+ T cell plays an important role in asthma chronic airway inflammation.(2)There were no significant difference in the level of CD4+ T cell,CD8+ T cell,CD4+/CD8+ T cell between the patients with asthma of mild degree and those of moderate or severe degree group,but CD 8+ T cell a little higer in the latler patlents,which still needs further research.

A novel ionization enhancer, methylamine formate, was proposed for improving the detection sensitivity of triglyceride in edible oil by reversed phase liquid chromatography electrospray ionization mass spectrometry (LC-ESI-MS).The commonly used isopropanol-acetonitrile-methanol-water and isopropanol-acetonitrile were selected as the mobile phase.By using a reversed phase C18 column, and taking the corn oil in isopropyl alcohol as sample solution, we compared methylamine formate with ammonium formate, as ionization enhancers, for their effect on the detection sensitivity of triglyceride by LC-ESI-MS after screening other different ionization enhancers, such as formic acid, acetic acid, ammonium formate, ammonium acetate, butyl formate, dibutylamine formate, triethylamine formate, diethylamine formate, methylamine formate, and ethylamine formate.The result indicated that, by using methylamine formate, the mass spectral peak response and the signal to noise ratio for trilinoleic glyceride component were 5 times higher than that of ammonium formate.The effect of the concentration of methylamine formate ionization enhancer, the flow rate of the mobile phase and the flow rate of nebulizing gas on the detection of methylamine formate were investigated.The concentration of triglyceride components in corn oil starting to form aggregates was similar in different mobile phases in the electrospray process according to measurement of the relationship between corn oil concentrations and the total ion chromatogram peak area of triglyceride.In particular, the peak area of trilinolein was linear with its concentration in the range of 7×10-7-2×10-4 mol/L (R2=0.9997), but increased slower in the higher concentration range.According to the experimental data, the mechanism for improvement of detection sensitivity of methylamine formate was suggested as that the addition of methylamine mono-charged ions with hydrophobic groups had lower solvation energy, which made the enriched addition ions easily evaporation from the droplet surface, thus improving the electrospray ionization efficiency.This method provided an effective way to improve the detection sensitivity of triglyceride in edible oil by LC-ESI-MS.

Androgen has broad biological effects. Androgen and its receptor exist widely in the cardio-cerebrovascular system and play an important protective effect in the multiple aspects of the occurrence and development of ischemic cerebrovascular disease (ICVD). In addition to involving in regulating the risk factors for ICVD, such as atherosclerosis,dyslipidemia, hypertension, coagulation-fibrinolysis abnormalities, obesity, and diabetes, androgen also has neuroprotective effect. This article reviews the protective effect of androgen in ICVD.

Disease bio-banks are an important strategic resource for medicine development. Such a bank with complete information and high information sharing enhances the competitiveness of medicine and promote the development of translational medicine. The present development of such banks is found with such setbacks as weak government leadership and standardization, as well as lack of a sharing mechanism. Therefore medical institutions should strengthen their standardization and informationization of disease bio-banks, which deserve sufficient government policy support and guidance. These efforts will help preserve our rich clinical resources, in addition to their integration and sharing for medicine advancement.
