ABSTRACT
Aim To explore the potential targets and mechanisms of Houpuwenzhongtang for the treatment of spleen and stomach deficiency cold stomach disease. Methods Firstly, TCMSP database, disease database and compound target prediction platform were used to collect active components, disease targets and predict potential targets. Secondly, Cytoscape 3.7.2 and String platform were used to screen key chemical components and core targets, and PPI network diagram was constructed. Finally, The active components with degree greater than 30 were used for molecular docking with key targets, and some docking results were selected for cell experiment. Results The key active components of Houpuwenzhongtang in the treatment of spleen and stomach deficiency cold stomach disease were hesperidin, magnolol, 6-gingerol, and so on. The key targets were JUN, AKT1, IL-8, etc.. The related pathways mainly involved immune response, signaling transduction, cell proliferation and apoptosis. Molecular docking results showed that the key active components had good binding activity with disease targets. The results of cell experiments showed that magnolol, hesperidin and 6-gingerol had different degrees of anti-inflammatory activity against IL-8 in a dose-dependent manner. Conclusions It is speculated that Houpuwenzhongtang may act on IL-8, JUN, AKT1 and other targets through magnolol, hesperidin,6-gingerol and other active ingredients, and participate in the regulation of PI3K-AKT signaling pathway, N F-K B signaling pathway for the treatment of spleen and stomach deficiency cold stomach disease. And it is found for the first time that 6-gingerol could stably bind to multiple disease targets related spleen and stomach deficiency cold stomach disease,such as AKT1,IL-8 and so on. The result suggests that 6-gingerol is worth further research. Through the results of IL-8 cell experiment, it is speculated that the components such as magnolol and hesperidin may play a role in gastric diseases caused by Helicobacter pylori infection by reducing the content of IL-8 in gastric mucosa.
ABSTRACT
Objective:To study the effect of combined decoction and single decoction of Houpu Wenzhongtang on rats with deficiency-cold of spleen and stomach from the perspective of metabonomics, to find out the relevant potential biomarkers and metabolic pathways, and to explore the similarities and differences between the combined decoction and single decoction, so as to provide reference for the feasibility analysis of replacing traditional decoction with single dispensing granule of this formula. Method:SD rats were randomly divided into normal group, model group, Houpu Wenzhongtang combined decoction group and simgle decoction group. Rats in the normal group were given distilled water by intragastric administration, rats in the other three groups were given cold vinegar at 4 ℃ in the morning and refined lard in the afternoon for 10 days (the dosage of 10 mL·kg-1). After the model was successfully established, rats in the combined decoction group and the single decoction group were given corresponding decoction with dosage of 1.8 g·kg-1 (according to the amount of crude drugs), once a day for 7 days. Ultra-high liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry (UPLC-Q-TOF-MS) technique was used to analyze the small molecular endogenous metabolites in urine. Orthogonal partial least squares-discriminant analysis (OPLS-DA) and principal component analysis (PCA) were used to compare the changes of differential metabolites among the normal group, model group, Houpu Wenzhongtang combined decoction group and single decoction group, and the differential metabolites were introduced into Kyoto Encyclopedia of Genes and Genomes (KEGG) for metabolic pathway analysis. Result:Compared with the model group, the Houpu Wenzhongtang combined decoction group and single decoction group jointly regulated 13 potential biomarkers, including phosphatidylcholine(PC), lysophosphatidic acid(LysoPA) and cholic acid, etc. They played a role in treating deficiency-cold of spleen and stomach by influencing metabolic pathways such as glycerophospholipid metabolism, glycerolipid metabolism, phosphatidylinositol signaling system and so on. The combined decoction and single decoction of Houpu Wenzhongtang could obviously restore the body weight, motilin and gastrin contents of rats with deficiency-cold of spleen and stomach to normal levels. Conclusion:According to biochemical indexes, there is no obvious difference between combined decoction and single decoction of Houpu Wenzhongtang, but according to metabonomics, the combined decoction may be slightly better than the single decoction. The research shows that it is feasible to replace traditional decoction with single dispensing granule of Houpu Wenzhongtang in clinical application.
ABSTRACT
OBJECTIVE@#To analyze the types of mental disorders caused by traumatic brain injury and the optimal time for forensic psychiatric appraisal. To explore the relationship between the degree of traumatic brain injury, the time of appraisal and the grade of intellectual deficiency.@*METHODS@#Five hundred and thirty-four forensic psychiatric cases of mental disorders caused by traumatic brain injury were retrospectively analyzed.@*RESULTS@#In the types of mental disorders caused by traumatic brain injury, the most cases were diagnosed as organic mood disorders (51.1%), following organic neurosis-like syndrome (24.0%) and organic intellectual deficiency (18.0%). For the disability grades, the most cases were the level VIII and IX disability grades, 219 cases (41.0%) and 177 cases (33.1%), respectively. The degree of brain injury and the degree of intelligence defection according to WAIS-RC were higher in intellectual deficiency group compared with non-intellectual deficiency group (P < 0.05). The grade of disability correlated with the degree of brain injury, the result of WAIS-RC, the result of cerebral CT scanning, and the grade of brain electrical activity mapping (BEAM) abnormality (P < 0.05). Nevertheless, the degree of intellectual deficiency did not correlate with appraisal time and the degree of brain injury (P > 0.05).@*CONCLUSION@#The factors influencing intellectual deficiency are complex. The findings of objective examination including cerebral CT scanning, BEAM, WAIS-RC and others should be considered as important indexes for disability evaluation.
