Establishment of combination of disease and syndrome animal model is an ideal technology platform in TCM research. Currently, many scholars have prepared matching IBS animal models combined typical animal models with etiology, which em-bodies the advantages of syndrome differentiation and promotes the development of combination disease and syndrome animal model. Even though, there still exists some problems about sub-jective evaluation on syndromes, paying more attention on dis-ease and less on syndromes. Therefore, we should deepen the pathogenesis of diseases and TCM syndromes research on animal model replication and improve the method of construction of combination of disease and syndrome animal model through the biological research of combination of disease and syndrome sys-tem. By this way, the idea of preparation animal models will be more mature and the scientific connotation of TCM will be pres-ented more exactly.

Objective: To develop a magnetic solid-phase extraction combined with gas chromatography-tandem mass spectrometry (GC-MS/MS) based on pyrrole-modified magnetic nanoparticles to determine 16 types of phthalic acid esters (PAEs) in commercial liquors. Methods : Fe3O4 magnetic nuclei were prepared by hydrothermal synthesis, and the polypyrrole-modified magnetic nanomaterials were prepared with the chemical oxidation method. Magnetic solid-phase extraction of beer, grape wine, rice wine and Chinese spirits was performed at 10% alcohol by volume, extraction duration of 20 min and ethyl acetate elution of 10 min, followed by addition of 1 g NaCl for reduction of emulsification effect. The 16 types of PAEs were determined using GC-MS/MS with DB-5MS capillary column (30 m×250 μm, 0.25 μm) under the mode of electron impact ionization (EI) and dynamic multiple reaction monitoring (dMRM), with quantitative analysis using the external standard method. The standard curve, detection limit, spike recovery rate and precision of GC-MS/MS for determination of 16 types of PAEs were evaluated. Results: Pyrrole was successfully embedded onto the surface of magnetic nanoparticles in the form of polymer, and the magnetic nanoparticles modified by polypyrrole were well characterized, showing unapparent matrix and emulsification effects. There was a good linear relationship for the 16 types of PAEs at 50 to 5 000 ng/mL (r=0.999 5-0.999 9), and the spike recovery rate of 16 types of PAEs ranged from 71.61% to 110.50% at 100, 500 and 1 000 μg/kg, with relative standard deviations of 3.78% to 7.41%, detection limits of 0.02 to 1.47 μg/kg. PAEs were detected in 20 out of 50 liquor samples, with 30.00%, 60.00%, 40.00% and 70.00% detection rates in beer, grape wine, rice wine and Chinese spirits, respectively. Conclusions This method is sensitive to determine 16 types of PAEs in liquor samples, with unapparent matrix and emulsification effects, and the polypyrrole-modified magnetic composite nanoparticles present high adsorption of PAEs in liquor samples, which is feasible for monitoring of PAEs in multiple types of liquor samples.

Objective: To investigate the contamination of phthalic acid esters (PAEs) and assess the health risk of PAEs contamination in market-available yellow rice wine in Huzhou City, Zhejiang Province, so as to provide the safety safeguard for consuming yellow rice wine. Methods: Yellow rice wine samples were collected from markets in Huzhou City from 2021 to 2022, and 16 PAEs were determined in yellow rice wine using magnetic solid-phase extraction coupled with gas chromatography-tandem mass spectrometry. The carcinogenic and non-carcinogenic risks of PAEs were evaluated using the health risk models proposed by United States Environmental Protection Agency. Results: A total of 75 yellow rice wine samples were collected, and 44 samples were detected with PAEs contamination (58.67%). Dimethyl phthalate (DMP), di-isobutyl phthalate (DIBP) and di-butyl phthalate (DBP) were detected, and there were 17 samples (22.67%) detected with DBP overdose (DMP and DIBP had no limit standard). DMP, DBP and DIBP, which were not classified as Class 2B and higher carcinogens by WHO's International Agency for Research on Cancer, had no definitive carcinogenic risks. Under mean PAEs, the five types of yellow rice wine all had no carcinogenic risks. Under 75% percentile of PAEs concentrations, the DBP in beverage wine with plastic packaging had a carcinogenic risk score of 1.207 5, with a gross carcinogenic risk score of 1.207 5. Under the maximum PAEs concentration, the ross carcinogenic risk scores of cooking wine with plastic packaging, beverage wine with plastic packaging, beverage wine with glass bottle packaging, and beverage wine with jar packaging were 2.751 0, 2.782 0, 1.298 2 and 2.944 0, presenting non-carcinogenic risks. Conclusion There is PAEs contamination in market-available yellow rice wine in Huzhou City, and no carcinogenic risk is evaluated. Non-carcinogenic health risk requires to be given a high priority.
