Ultra-performance liquid chromatography-quadrupole time of fight/mass spectrometry(UPLC-Q-TOF-MS) and UNIFI were employed to rapidly determine the content of the components in Liangxue Tuizi Mixture. The targets of the active components and Henoch-Schönlein purpura(HSP) were obtained from SwissTargetPrediction, Online Mendelian Inheritance in Man(OMIM), and GeneCards. A "component-target-disease" network and a protein-protein interaction(PPI) network were constructed. Gene Ontology(GO) functional annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were performed for the targets by Omishare. The interactions between the potential active components and the core targets were verified by molecular docking. Furthermore, rats were randomly assigned into a normal group, a model group, and low-, medium-, and high-dose Liangxue Tuizi Mixture groups. Non-targeted metabolomics was employed to screen the differential metabolites in the serum, analyze possible metabolic pathways, and construct the "component-target-differential metabolite" network. A total of 45 components of Liangxue Tuizi Mixture were identified, and 145 potential targets for the treatment of HSP were predicted. The main signaling pathways enriched included resistance to epidermal growth factor receptor tyrosine kinase inhibitors, phosphatidylinositol 3-kinase/protein kinase B(PI3K-AKT), and T cell receptor. The results of molecular docking showed that the active components in Liangxue Tuizi Mixture had strong binding ability with the key target proteins. A total of 13 differential metabolites in the serum were screened out, which shared 27 common targets with active components. The progression of HSP was related to metabolic abnormalities of glycerophospholipid and sphingolipid. The results indicate that the components in Liangxue Tuizi Mixture mainly treats HSP by regulating inflammation and immunity, providing a scientific basis for rational drug use in clinical practice.

Cerebrovascular diseases have the characteristics of high morbidity, high disability, high mortality and high recurrence rate, which seriously harm human health and increase the national health economic burden. 3-n-Butylphthalide (NBP) is a new drug commonly used in clinical treatment of cerebrovascular diseases, and it is also one of the main active components in traditional Chinese medicine such as Angelica sinensis and Chuanxiong. In this review, the pharmacological effects of NBP were systematically summarized. Studies have shown that NBP has pharmacological effects such as antiplatelet aggregation, anti-thrombosis, inhibiting neuronal apoptosis, anti-oxidation, anti-cerebral ischemia, anti-brain injury, and anti-vascular dementia. In clinical practice, it is often combined with edaravone, alteplase, fasudil, Xingnaojing injection, and compound Danshen injection to treat cerebral vascular diseases such as stroke, vascular dementia, and cerebral vasospasm, and plays a good synergistic effect. This summary could provide support for the rational clinical application of NBP, and also provide basis for the in-depth study of the interaction of its drug combination.

Aim To study the effect of drug-containing serum of Schisandra Chinensis Fructus and compatible with Glycyrrhizae Radix Et Rhizoma -on lipid accumulation in hepatocytes and explore the related mechanism. Methods SD rats were given Schisandra Chinensis Fructus (SF, 3.9 g • kg"1), Schisandrae Chinensis Fructus-Glycyrrhizae Radix Et Rhizoma (SG, 1 : 1, 1 '• 1. 5, the extract 3. 9 g • kg"1 in crud of Schisandrae Chinensis Fructus), once per day, the drug-containing serum was prepared after seven days of continuous administration. Conventional cultivation of human normal hepatocytes (L02 cells) in vitro, cells were divided into blank control group, SF group, and SG(1 : 1 and 1 : 1.5) group. After 48 hours' treatment , lactate dehydrogenase ( LDH) release was detected by the kit, the levels of intracellular triglyceride (TG) and total cholesterol (TC) were detected by biochemical method. The mRNA expression levels of PPAR-a, PPAR-7, Fabpl/2, SREBPlc, ACCa and FAS were detected by the real-time reverse tran scrip- tion polymerase chain reaction ( RT-PCR ). Results The biochemical results showed that compared with the blank group, the content of TG and TC in SF group increased significantly (P < 0. 05 ) , the mRNA expres sion of PPAR-a and PPAR-7 in SF group was significantly reduced, and the mRNA expression of SREBPlc and ACCa markedly increased ( P < 0.05, P < 0.01). When compared with SF group, the levels of TG and TC in SG (1 : 1) group were significantly reduced (P <0. 05) , the mRNA expressions of Fabpl/2 and FAS in SG (1 : 1) group were significantly reduced, while the mRNA expression of SREBPlc significantly increased ( P < 0. 05, P < 0. 01 ). TC content in SG (1 : 1.5) group significantly decreased (P < 0.05 ) and the mRNA expression of PPAR-7, SREBP1 c in SG (1 : 1.5) significantly increased, but the Fabpl/2 and FAS markedly decreased (P <0. 05, P < 0. 01). Conclusions SF containing serum can significantly increase the content of TG and TC in hepatocytes , and the SG containing serum can significantly improve the elevated TG and TC contents and reduce lipid accumulation. The mechanism may be related to the regulation of mRNA expression of PPAR-a, PPAR- 7, Fabpl/2, SREBPlc, ACCa and FAS.
