ABSTRACT
Enzyme-linked immunosorbent assay(ELISA) and metabolomics were used to analyze and compare two animal models of heart-kidney insomnia, in order to explore a more ideal animal model and preliminarily explore the essence of heart-kidney insomnia. Based on the clinical symptoms and disease characteristics of heart-kidney insomnia, the animal model of heart-kidney insomnia was reproduced through intraperitoneal injection with p-chlorophenylalanine(PCPA) and multi-factor interaction. The animal model of disease-syndrome combination was evaluated by behavioral observation, ELISA and metabolomics. Wistar rats were randomly divided into normal group, PCPA group and compound model group(FH). The rats' behavior, body weight, adrenal index and spleen index were recorded. The levels of corticotropin releasing hormone(CRH) and adrenocorticotropin(ACTH) in serum were detected by ELISA, and the differential metabolites in serum were detected by UPLC-QE-MS. The body weight and adrenal index in FH group were significantly lower than those in PCPA group(P<0.05); whereas ACTH and CRH in FH group were significantly higher than those in PCPA group by ELISA; nine potential biomarkers were identified by serum sample statistics. There were four main metabolic pathways in cardiorenal insomnia pentose phosphate metabolism, alanine, aspartic acid and glutamic acid metabolism, histidine metabolism, and taurine and subtaurine metabolism. PCPA and multi-factor interaction method can successfully replicate the insomnia model, but multi-factor modeling method is more similar to clinical traditional Chinese medicine syndrome. Animal behavior, ELISA and metabolomics were used to evaluate the rat model of cardiorenal insomnia from in vitro to in vivo, from macro to micro, and from individual to the whole.
