ABSTRACT
Using the lipidomics method based on UHPLC-Q-Exactive Orbitrap/MS, the change of phospholipid metabolism in lung tissue of mice induced by lipopolysaccharide (LPS)-induced acute lung injury was analyzed to observe the regulation of abnormal lipids by Jiegeng Decoction and to explore the regulation effect of Jiegeng Decoction on LPS-induced acute lung injury. The lung tissue samples from control group, model group, dexamethasone (positive drug) group, and Jiegeng Decoction group were collected and the lipid components of the sample were extracted. All procedures over mice were performed in accordance with the Guidelines for Care and Use of Laboratory Animals of Nanjing University of Chinese Medicine, and the experiments were approved by the Animal Ethics Committee of our university. The lipidomics technique of UHPLC-Q-Exactive Orbitrap/MS was used to study change of phospholipids in lung tissue of each group. LPS induced acute lung injury in mice with metabolic abnormalities of phospholipids, the specific performance of the PC was significantly upregulated, phosphatidyl ethanolamine (PE), phosphatidyl glycerol (PG), phosphatidyl serine (PS),phosphatidylinositol (PI) and other metabolic disorders, Jiegeng Decoction have a certain role in these phospholipids. LPS-induced acute lung injury caused disturbances of phospholipid in vivo, and Jiegeng Decoction regulates metabolic phospholipids.
ABSTRACT
Exhaled breath condensate (EBC) was analyzed by gas chromatography-mass spectrometry (GC-MS / MS) in childhood asthma and healthy control, aiming to find the potential markers of EBC in children with asthma, and provide a scientific reference for its pathogenesis and early screening. EBC samples were collected from 21 asthmatic children (age (8. 2 ±1. 6) years) and 17 healthy children ( age (8. 1 ±1. 3) years). GC-MS / MS was used to obtain the full scan data of chemical components. Cluster analysis was performed on the two groups of metabolites by principal component analysis (PCA), and potential biomarkers were found using Metaboanalyst 3. 0 attributable metabolic pathways. The results showed that the EBC metabolic maps of asthmatic group and normal group were very different, and eight endogenous potential biomarkers were identified, suggesting that starch and sucrose metabolism, lysine degradation, aminoglycan nucleoside metabolism, phenylalanine metabolism may play important roles in the development of asthma in children.
ABSTRACT
Objective To explore the changed trend of endogenous lipid metabolites in rats with rheumatoid arthritis during different disease periods and the regulation of Zushima Tablets on differential metabolites based on UPLC-Q-Exactive Orbitrap MS. Methods The collagen-induced arthritis (CIA) rats were established using bovine type II collagen. The serum samples were collected before (0 d) and 14, 21, and 36 d after model construction from control, model, and Zushima Tablets groups [0.6 g/(kg•d)], respectively. The lipids were extracted and identified by bioinformatics analysis to find the lipid differential metabolites. Results It was obviously observed that lipid metabolism disordered in CIA rats compared with the control group. The content of three acylcarnitines was increased significantly while the level of TG showed a downward trend in the CIA model group when the TG carbon chain was shorter than 58 carbon atoms. To the opposite, the content of TG substances with atomic number greater than fifty-eight in the model group was significantly higher than that of the control group. Zushima tablet obviously regulated the metabolism levels of a phosphatidylserine, a ceramide, two acylcarnitines, four phosphatidylcholines, and four triglycerides. Conclusion This study demonstrated that rheumatoid arthritis caused the disorder of lipid metabolism while Zushima Tablets had regulatory effects on some lipid metabolites.

ABSTRACT
Objective: To observe the regulating action of Zushima Gancao Tablet on abnormal metabolites by analyzing the changes of endogenous metabolites in plasma of rheumatoid arthritis (RA) rats, and to explore the mechanism of Zushima Gancao Tablet in treating RA from the perspective of metabonomics. Methods: Rats were divided into normal group (NG), model group (MG), positive medicine group (PMG), and Zushima Gancao Tablet group (ZGG). Adjuvant arthritis (AA) rats were established with freund complete adjuvant, rats in PMG and ZGG groups were ig administered with tripterygium glycosides and Zushima Gancao Tablet respectively for a month. Plasma samples were collected on days 1, 10, 20, and 28 before and after administration. UPLC/LTQ-Orbitrap-MS was applied to analyzing the metabolic profile changes of each group in different durations of the disease and mechanism of drug intervention. Results: The related pathways of AA mainly involved metabolisms of amino acids, lipids, nucleic acids, and vitamins. Zushima Gancao Tablet had great effect on AA by regulating 12 biomarkers. Conclusion: Small molecule metabolites in AA rats are deviated from the normal ones. The effects of Zushima Gancao Tablet and positive medicine (tripterygium polyglycoside) on AA are similar, but the mechanisms were different. Zushima Gancao Tablet down-regulates the level of LPC in secondary lesions while tripterygium polyglycoside tablets could effectively inhibit the metabolisms of a variety of amino acids during acute inflammation.
ABSTRACT
The objective of the present study was to establish a method based on principal component analysis (PCA) for the study of transdermal delivery of Chinese medicinal formulae, and to choose the best penetration enhancers for Qingfei Xiaocuo gel depend on this method. Using improved Franz type diffusion cell and excised rat skin in vitro as transdermal barrier, the receptive solution fingerprint was established by HPLC, harvesting the areas of the common peaks in the fingerprint, then the total factor scores of the concentrations at different times were calculated using PCA and were employed instead of the concentrations to compute the cumulative amounts (Q12) and enhancement ratio (ER), the latter of which were considered as the indexes for optimizing penetration enhancers. Compare to the control group, the ER of the other groups increased significantly and furthermore, 2.5% azone with 2.5% menthol manifested the best effect. PCA represent most information in the receptive solution, the method above could choose the best penetration enhancers, it could be a reference for the study of transdermal delivery of Chinese medicinal formulae.
