The pharmaceutical composition of the present invention is characterized by high stability of its radiolabeled complex against radiolytic degradation. The present invention also provides a method for preparing such a pharmaceutical composition, and use of para-aminohippuric acid or a pharmaceutically acceptable salt or carboxylic derivative thereof for the stabilization of the radiolabeled complex of such a pharmaceutical composition.

The application provides a molecular imprinting electrochemical sensor for hippuric acid detection, a preparation method and a segmented response technology, and belongs to the technical field of electrochemical sensors.The molecular imprinting electrochemical sensor for detecting hippuric acid is prepared by an electrochemical polymerization method based on a functional monomer aniline and o-phenylenediamine and taking hippuric acid as a template molecule.The sensor combines the advantages of molecular imprinting technology and electrochemical technology, has excellent sensitivity, fast response time and specific recognition ability, has good signal response for hippuric acid detection under different concentrations, generates a good electric signal in a 0-100nM hippuric acid solution, and forms a better linear relationship between the electric signal and the concentration in a hippuric acid solution with a concentration of more than 100nM, so that the signal response and detection range of the molecular imprinting electrochemical sensor under high concentration are widened, and the molecular imprinting electrochemical sensor is suitable for hippuric acid detection under a wide range.

The invention discloses application of hippuric acid in activation of brown adipose tissue heat production and prevention and treatment of obesity, and the application is realized by activating brown adipose tissue heat production, specifically, expression of uncoupling protein 1 in brown adipose tissue is up-regulated, heat production capacity under cold stimulation conditions is enhanced, weight gain and abnormal glucose and lipid metabolism are improved, and the purpose of preventing and treating obesity is achieved. The hippuric acid is preferably derived from walnut oil or metabolites thereof, and has a good application prospect.

The application discloses application of hippuric acid in preparation of a medicine for preventing and / or treating depression, and belongs to the technical field of biological medicine. The hippuric acid or pharmaceutically acceptable salt thereof has significant and multi-target antidepressant pharmacological activity through chronic mild stress depression animal model experiment. Specifically, in terms of improving core depressive symptoms, the sugar water preference experiment result shows that the hippuric acid can effectively reverse CUMS-induced hedonic deficiency of mice, and significantly improves the sucrose preference rate, and the forced swimming experiment proves that the hippuric acid can significantly shorten the immobility time of mice and relieve behavioral despair; in terms of improving anxiety-like behavior, the mine field experiment data show that after the hippuric acid intervention, the number of times of entering the central area, the residence time and the total activity distance of the depressive model mice are all significantly increased, which indicates that the hippuric acid can effectively improve the spontaneous activity reduction caused by chronic stress.

The application provides an anisaldehyde hippuric acid molecular top and a preparation method and application thereof, and belongs to the technical field of detection of gibberellic acid liquid preparation. The anisaldehyde hippuric acid molecular top has a unique configuration of a rigid aromatic ring rotor and an amide bond flexible support shaft, can convert micro-viscosity changes into visual light signal output, and releases light signal intensity that regularly increases with the increase of micro-viscosity, so that the dilution degree of the gibberellic acid liquid preparation can be observed in real time and accurately controlled. The sensitive coefficient of the MBABG to viscosity is high (x=0.65), the conjugated system formed by the amide bond and the aromatic ring in the molecular structure of the MBABG gives the MBABG excellent chemical stability, the MBABG can resist the complex environment of multiple components such as thickening agents, surfactants and pH regulators in the gibberellic acid liquid preparation, and can exist stably for a long time.

The invention discloses an animal model construction method for fetal osteoporosis, a prevention and treatment target and application of the prevention and treatment target. The fetal osteoporosis animal model is a filial generation rat which is obtained after a pregnant female Wistar rat is subjected to intragastric administration of Acimoline (300 mg / kg. D) in the pregnancy period. Weaning is conducted four weeks after birth, male and female are separated from cages and fed to 12 weeks, the peak bone mass of female offspring is remarkably reduced, and therefore the animal model with exposed Acimoline during pregnancy is established. On the basis of a pregnancy-stage Acimoline exposed rat model, 20 mg / kg hippuric acid is intragastric injected in the pregnancy stage, and peak bone mass reduction of female offspring can be effectively corrected. The animal model established by the invention is novel, reliable, simple and convenient, and application of hippuric acid in screening and preparing medicines for preventing and treating fetal osteoporosis is determined.
