ABSTRACT
Polysaccharide of Balanophora involucrata Hook. f. (BPS), the major component of Balanophora involucrata Hook. f., was confirmed the protective effect on liver injury in our previous study. This research aimed to investigate the protective mechanism of BPS on experimental liver injury by attenuating cell ferroptosis through modulating solute carrier family 7 member 11/glutathione peroxidase 4 (SLC7A11/GPX4) pathway. The animal experiment was approved by the Experimental Animal Ethical Committee of Hubei Minzu University and all rats had received human care in compliance with the institutional animal care guidelines. Rats were given intraperitoneal injection of (D-galactosamine, D-GalN) solution (800 mg·kg-1) one time to establish the acute liver injury model. The results showed aspartate amino transferase (AST), alanine aminotransferase (ALT) and 4-hydroxynonenal (4-HNE) levels in serum were decreased, and the contents of reactive oxygen species (ROS), Fe2+, malondialdehyde (MDA) and lipid peroxide (LPO) in liver tissues also decreased and glutathione (GSH) level increased after BPS administration with 200 mg·kg-1. Besides, BPS reduced iron deposition and increased the expression of SLC7A11 and GPX4 proteins in liver tissue. In conclusion, BPS ameliorated experimental liver injury by alleviating cell ferroptosis through SLC7A11/GPX4 pathway. The present study pointed to the possibility of utilizing BPS for protection against liver injury in clinic.
ABSTRACT
To explore the mechanism of ovarian toxicity of Hook. F. (TwHF) by network pharmacology and molecular docking. The candidate toxic compounds and targets of TwHF were collected by the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and the Comparative Toxicogenomics Database (CTD). Then, the potential ovarian toxic targets were obtained from CTD, and the target genes of ovarian toxicity of TwHF were analyzed using the STRING database. The protein-protein interaction (PPI) network was established by Cytoscape and analyzed by the cytoHubba plug-in to identify hub genes. Additionally, the target genes of ovarian toxicity of TwHF were subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses by using the R software. Finally, Discovery Studio software was used for molecular docking verification of the core toxic compounds and the hub genes. Nine candidate toxic compounds of TwHF and 56 potential ovarian toxic targets were identified in this study. Further network analysis showed that the core ovarian toxic compounds of TwHF were triptolide, kaempferol and tripterine, and the hub ovarian toxic genes included , , , , , , , , and . Besides, the GO and KEGG analysis indicated that TwHF caused ovarian toxicity through oxidative stress, reproductive system development and function, regulation of cell cycle, response to endogenous hormones and exogenous stimuli, apoptosis regulation and aging. The docking studies suggested that 3 core ovarian toxic compounds of TwHF were able to fit in the binding pocket of the 10 hub genes. TwHF may cause ovarian toxicity by acting on 10 hub genes and 140 signaling pathways.

ABSTRACT
Objective To study the intestinal absorption kinetics of Tripterygium wilfordii (TW) solid dispersions and the effects of different intestinal segments, drug concentrations, pH value, and P-glycoprotein (P-gp) on intestinal absorption. Methods The absorption behavior was investigated in situ with a single-pass intestinal perfusion (SPIP) model in rats. The content of each index component was determined by HPLC. The gravimetric method was used to correct the data and calculate the absorption rate constant (Ka) and apparent permeability coefficient (Papp) of each index component. Results The index components of TW were absorbed in the whole intestine, and the absorption rate constant (Ka) of all the index components of TW solid dispersion was significantly increased than that of extract (P < 0.05), and had some differences among different segments. With the increase of drug concentration, the absorption of each index component had saturation phenomenon, which indicated that it may be carrier-mediated transport mechanism. Acidic environment (pH 5.4) was beneficial to the absorption of various index components, especially the acidic content celastrol. After adding P-gp inhibitor, the Ka and Papp of celastrol were significantly different from those without P-gp inhibitor (P < 0.05), which suggested that it may be the P-gp substrate. Conclusion All the index components of TW solid dispersion are absorbed in the whole intestine and have saturation phenomenon, which suggested the absorption may be carrier-mediated transport mechanism. Acidic environment is beneficial to the absorption of all components. The absorption process of celastrol is affected by drug concentration and P-gp inhibitor, which indicated that it may be P-gp substrate. The preparation of solid dispersing can significantly enhance the absorption of various components of TW, suggesting that all the index components are BCS II drugs, and the bioavailability of the preparation may be improved.
ABSTRACT
As a major active component extracted from traditional Chinese herb Tripterygium wilfordii Hook F, triptolide exhibits multiple pharmacological effects. Autophagy is an evolutionary conserved intracellular catabolic process involved in cytoplasmic materials degradation. Autophagic dysfunction contributes to the pathologies of many human diseases, which makes it a promising therapeutic target. Recent studies have shown that triptolide exerts neuroprotection, anti-tumor activities, organ toxicity, and podocyte protection by modulating autophagy. This article highlights the current information on triptolide-modulated autophagy, analyzes the possible pathways involved, and describes the crosstalk between autophagy and apoptosis modulated by triptolide, in hope of providing implications for the roles of autophagy in pharmacological effects of triptolide and expanding its novel usage as an autophagy modulator.

Tripterygium wilfordii Hook F (TwHF) and its extracts have long been used for the treatment of rheumatoid arthritis, autoimmune diseases, and kidney disease due to their anti-inflammatory, immunoregulatory, and other pharmacological effects. However, the clinical immunoregulatory effects of TwHF and its extracts remain unclear, so we reviewed their effects for use in clinical practice. This review provides a comprehensive summary of the recent literature on the immunoregulatory effects of TwHF and its extracts in clinical studies. TwHF and its extracts affect the proliferation and activation of Tand B cells; ratio of Tcell subsets; inflammatory response of monocytes, macrophages, and immunoglobulins; and secretion of many cytokines. Together, these effects dictate immune function in a variety of diseases. TwHF and its extracts can be used alone or in combination with existing therapies against many immune disorders through immunomodulation.
