Based on network pharmacology,this study predicted the potential molecular mechanism and related pathways of the protective effect of traditional Chuanxiong Rhizoma,a traditional Chinese herb,on glaucomatous optic nerve injury,and conducted in vitro experimental verification of the predicted results of network analysis.We analyzed the molecular mechanism of Chuanxiong Rhizoma in the potential treatment of glaucoma by revealing its main active ingredients and predicting its targets,so as to provide reference for subsequent basic research.Network pharmacological research results showed that the potential hub targets and key signaling pathways of Chuanxiong Rhizoma in the treatment of glaucoma were closely related to biological processes such as apoptosis,autophagy,inflammation,oxidative stress and angiogenesis.Molecular docking showed that many active ingredients,such as chrysophanol(CHR),myricanone and retinol,could combine well with their target proteins by intermolecular forces,especially CHR had strong binding ability with each target.We speculated that the main active component of Chuanxiong Rhizoma might be involved in the regulation of PI3K-Akt,Nod-like receptor,IL-4 and IL-13,MAPK,AGE-RAGE and neurotrophin signaling pathway by regulating of PI3K,Akt,TLR4,RAGE,NTRK2 and other key targets.Furthermore,it may achieve multi-directional intervention on apoptosis/autophagy,inflammation/immunity,oxidative stress and nutrient metabolism of axoplasma flow,and then delay the degeneration of optic nerve injury.In vitro experiments showed that the active component CHR of Chuanxiong Rhizoma could reverse the M1-type polarization and autophagy/apoptosis of mouse microglia(BV2)induced by lipopolysaccharide(LPS)at the transcriptional level.Meanwhile,the expression of inflammatory mediators IL-1βand TNF-αwas inhibited,and the mRNA level of anti-inflammatory factor IL-10 was significantly increased.In addition,CHR down-regulates activation of the RAGE-NOX4 pathway mediated by LPS in reducing oxidative stress.In this study,network pharmacology and molecular docking technology were integrated for the first time to explore the potential molecular mechanism of traditional Chinese herb“Chuanxiong Rhizoma”in the treatment on glaucoma,and CHR was innovatively proposed as an important ingredient in Chuanxiong Rhizoma that plays a protective role in the damage of optic nerve.Preliminary verification was conducted through in vitro experiments.The results suggest that Chuanxiong Rhizoma may interfere with autophagy and apoptosis,inhibit immune inflammation,as well as reduce oxidative stress in the treatment of glaucoma through the active components represented by CHR,so as to resist progressive optic nerve injury.Our study provides theoretical basis for the clinical use of Chinese herbal medicine or its extract in glaucoma,and also lays a solid foundation for the research of Chinese medicine in the field of optic nerve protection. 展开更多

Extracts from Rhizoma Acori Tatarinowii (Grassleaf Sweetflag Rhizome, Shichangpu) have been shown to improve learning and memory, reduce anxiety, allay excitement, and suppress seizures. Rhizoma Acori Tatarinowii extracts interact with y-aminobutyric acid and activate the y-aminobutyric acid type A receptor, although few studies have addressed the precise effects of v-aminobutyric acid type A receptor al subunit. In the present study, y-aminobutyric acid type A receptor al subunit protein expression in the cerebral cortex and hippocampus, and pathological scores of brain injury, were significantly greater following recurrent seizures, but significantly decreased following treatment with Rhizoma Acori Tatarinowii extracts. These results indicated that Rhizoma Acori Tatarinowii extracts down-regulated y-aminobutyric acid type A receptor al subunit protein expression in the cerebral cortex and hippocampus and protected seizure-induced brain injury during development. 展开更多

Methods: Four kinds of experimental ulcer models were established respectively by water-immersion stress, intragastric ethanol, acetic acid erosion, and pylorus ligation. The anti-ulcer effects of TA were evaluated, and compared with that of berberine (Bet) and cimetidine (Oim). Results: TA showed significant inhibitory effects on ulcerative formation induced by water-immersion stress, intragastric ethanol, and pylorus l igation in dose-dependent manner, and showed therapeutic effect on acetic acid erosion-inducing ulcer, in comparison with the control group. The anti-ulcer activity of Bet was less than TA containing equal content of Bet. TA significantly reduced the free acidity, total acidity and total acid output, but didn't affect the gastric juice volume, gastric pepsin activity, adherent mucus quantity of stomach wall and free mucus dissolving in gastric juice. The suppressive activities of TA on gastric acid secretion didn't occur when it was administered into dodecadactylon at a dose of 360 mg/kg wt. Moreover, when compared with Oim, the inhibitory effect of TA on gastric acid secretion isn't proportional to the inhibitory effects on the formation of the 4 kinds of experimental ulcers. Conclusion: TA is a potent candidate in therapeutic drugs for treating gastric ulcer. Its anti-ulcer effective components and mechanism is not only related to Bet and inhibition of gastric acid, but also to other ingredients of TA and mechanism so far unknown. 展开更多

Objective:To investigate the effects of Gastrodiae rhizoma,a dried root of Gastrodia elata Blume,on proliferation and differentiation of human NSCs derived from embryonic stem cells.Methods:A 70%ethanol extract of Gastrodiae rhizoma(EEGR) was estimated with4-hydroxybenzyl alcohol as a representative constituent by HPLC.Results:MTT assay showed that the treatment with EEGR increased the viability of NSCs in growth media.Compared to contro1,EEGR increased the number of dendrites and denritic spines extended from a differentiated NSC.Whereas EEGR decreased the mRNA expression of Nestin,it increased that of Tuj1 and MAP2 in NSCs grown in differentiation media.Immunocytochemical analysis using confocal microscopy also revealed the increased expression of MAP2 in dendrites of EEGR-treated NSCs.Furthermore,EEGR decreased mRNA expression of Sox2 in NSCs grown even in growth media.Conclusions:In conclusion,our study demonstrates for the first time that EEGR induced proliferation and neuronal differentiation of NSCs,suggesting its potential benefits on NSC-based therapies and neuroregeneration in various neurodegenerative diseases and brain Injuries. 展开更多
