When used alone, nepetalactone attracted mosquitoes to the trap of the olfactometer, however, when mixed with human odor or a L-lactic acid dichloromethane solution, nepetalactone inhibited the attractiveness obviously. Nepetalactone exhibited a spatial repellency, but was not an ideal topical repellent. DEET did not have the attractiveness to mosquitoes, and did not exhibit inhibition on L-lactic acid dichloromethane solution too, hut enhanced the attractivity of human odor to mosquitoes.

Results: The changes following hydrocortisone intervention of rats could be identified by PCA, and the kidney deficiency syndrome rats entered a state of "hyperfunction", involving a series of changes in metabolic pathway and metabolic network. The response integral area of lactic acid (δ 1.37) increased, indicating the accumulation of metabolites of lactic acid. The amount of dimethylamine (δ 2.72) also increased, indicating that the disorder of kidney function was related to kidney-deficiency syndrome. The response of creatinine (δ 3.87), asparaginic acid (δ 2.83), taurine (δ 3.44, 3.28), and hippurate (δ 7.84, 7.56, 7.64, 3.97) all decreased significantly, indicating that the hydrocortisone might cause adrenal cortex excretion injury. The response integral area of succinate (δ 2.41) and citric acid (δ 2.53, 2.68) decreased, which was usually caused by disorder of the mitochondrial function.
