Objective:To determine the relationship between plasma fatty acid composition and glucose and insulin concentrations during 50g glucose tolerance test(GTT).

Serum phospholipid fatty acids were analyzed with capillary gas chromatography.

Objective To observe the dynamic changes of plasma lysophosphatidic acid(LPA)in patients with acute cerebral thrombosis(CT),investigate the role of plasma LPA in reflecting the blood platelet activated state during the process of CT occurrence and development and provide objective evidence for individualized therapy of anti-blood platelets.

Objections Observing the dynamic changes of plasma Lysophosphatidic acid(LPA) content in patients with Acute Cerebral Thrombosis(CT);discussing plasma LPA reflecting the blood platelet activated state in CT occurrence and condition successional variation process;providing objective basis for individuation therapeutic schedule about the treatment of the anti-blood platelets.

Basic soil properties,phospholipid fatty acid(PLFA),acid(alkaline)phosphatase activities and soil microbial biomass C or N(SMB-C or N)were measured.

The effect of manure(MCK) and combined application of chemical fertilizers(NPK) on soil microbial biomass and structure were studied by measuring soil microbial biomass carbon(nitrogen) and phospholipid fatty acid(PLFA) in different microbial communities,with the nil-fertilization(CK) and fallow as controls.
