A consensus on the management of allergy in kindergartens and primary schools / 中国学校卫生

Abstract@#Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

Research Progress of Proton Transfer Reaction Mass Spectrometry in the Field of Breathing Gas Detection / 生物医学工程学杂志

Breathing gas carries important physiological information. Technology for detection of breathing gas has become a research focus because of the advantages of nondestructive sampling and convenient operation. Proton transfer reaction mass spectrometry (PTR-MS) plays an irreplaceable role because of the advantages of high sensitivity, fast response and good specificity. In this paper, the principle of PTR-MS is introduced first, followed by research progress of PTR-MS in the field of breathing gas detection. Factors influencing the test results are analyzed. Finally, future prospects of development for PTR-MS in the field of breathing gas detection are discussed.

A PHARMACOLOGICAL STUDY OF TERMINATION OF EARLY PREGNANCY BY ADMINISTRATION OF 15-METHYL PROSTAG LANDIN F2a ALONE AND IN COMBINATION WITH TESTOSTOS- TERONE PROPIONATE / 中国药理学通报

15-methyl prostaglandin F2a (PGF2a) in a dose of 0.2 rag/kg B. W.combined with testosterone propionate ( TP ) in a dnse of 25mg/ kg B. W. was better than 15-methyl PGF2a alone in a dope of 0.2mg/ kg B. W. on termination of early pregnancy in rats.The endometriurn necrosis only in the uterine deciduous of rats treated with TP.All the above results show that the combined administration of 15 methyl PGF2a and TP is better than the administration of 15-methyl PGF2a alone. TP can probably strengthen the abortion effect of 15-rnethyl PGF2a.
