ObjectiveTo elucidate the mechanism of Osteoking against fracture， femoral head necrosis， osteoarthritis， and lumbar disc herniation by integrating heterogeneous information network mining and experimental validation. MethodOn the basis of the disease-related database and transcriptome expression profiling dataset， as well as the ETCM database， the gene sets related to four target diseases and the candidate target spectrum of Osteoking were obtained through the integration and analysis of bioinformatics data， and a "disease-syndrome-formula-target-pathway-effect" heterogeneous information network was constructed. In addition， by functional enrichment analysis， the core targets of Osteoking in interfering with the imbalance network of four kinds of bone injury diseases， the biological pathways involved， and the corresponding clinical symptoms were screened， and they were verified in animal experiments. ResultHeterogeneous information network mining indicates that Osteoking may commonly reverse the imbalance networks of fracture， femoral head necrosis， osteoarthritis， and lumbar disc herniation via regulating cell function and activity， inhibiting inflammatory response， reducing bone destruction， and improving the immune function of the body by modulating relevant core candidate targets such as RAC-alpha serine/threonine-protein kinase （Akt1）， catenin beta-1 （CTNNB1）， epidermal growth factor receptor （EGFR）， heat shock protein 90-alpha （HSP90AA1）， and phosphatidylinositol 3-kinase catalytic subunit alpha isoform （PI3KCA）， as well as related biological pathways such as phosphatidylinositide 3-kinases/protein kinase B （PI3K/Akt）， janus kinase/signal transducer and activator of transcription （JAK/STAT）， tumor necrosis factor （TNF）， nuclear factor kappa-B （NF-κB）， and Toll-like receptors. In particular， Osteoking may improve the blood supply of the fracture end by regulating blood circulation at the target site of the disease， and it may maintain the balance of bone metabolism by regulating hormone-related pathways to promote fracture healing. In addition， Osteoking may relieve lipid metabolism disorders by targeting and regulating lipid-related pathways， accelerate bone formation and bone repair， and delay the progression of femoral head necrosis. Osteoking may relieve the symptoms of pain by acting on neurological pathways to reduce local nociceptive stimulation in patients with osteoarthritis and lumbar disc herniation. Further experimental validation demonstrates that the PI3K/Akt signaling pathway is the most significantly enriched pathway for the key network targets of Osteoking for the four diseases. The candidate target of Osteoking may have the strongest association with the network of fracture-related genes. Therefore， this study chooses fracture as the target disease to verify the efficacy of Osteoking. The results show that Osteoking can accelerate bone formation and promote fracture healing by inhibiting the activation of the PI3K/Akt signaling axis. ConclusionThe study shows that the main mechanism of "treating different diseases with an identical treatment" of four bone injury diseases with Osteoking involves cell function regulation and immune inflammation-related signaling pathways. Further experimental validation identifies that the PI3K/Akt signaling axis may be one of the key pathways of Osteoking to promote bone regeneration， bone reconstruction， and bone metabolism homeostasis.

ObjectiveTo systematically explore the roles and contributions of the sovereign drug Gypsum Fibrosum contained in Baihu Guizhitang （BHGZT） against rheumatoid arthritis （RA） with heat syndrome from property-efficacy association by an approach integrating transcriptomics with gene regulatory network analysis. MethodA total of 20 male Lewis rats were randomly assigned into 4 groups： a control group （n=5）， a group of adjuvant-induced arthritis rat model with heat syndrome （AIA-H， n=5）， an AIA-H + BHGZT group （BHGZT， 21.4 g·kg^-1， n=5）， and an AIA-H + BHGZT without Gypsum Fibrosum group （BHGZT-GYP， 10.7 g·kg^-1， n=5）. We combined the gene expression profiling based on AIA-H rat model and "disease-gene-drug effective target" network analysis to predict the major function of Gypsum Fibrosum contained in BHGZT against RA with heat syndrome. Furthermore， in vivo experiments with the AIA-H rat model were performed to validate the therapeutic effects on the severity of arthritis based on the representative images of arthritis， limb diameter， infrared thermography， pain thresholds， and joint injury， as well as at the level of immunity-inflammation imbalance. Oil Red O staining was employed for the differentiation of 3T3-L1 pre-adipocytes in the AIA-H rats treated by BHGZT， BHGZT-GYP， and GYP. ResultGene expression profiling and network analysis demonstrated that Gypsum Fibrosum mainly regulated the energy metabolism disorders and the immunity-inflammation imbalance during the development and progression of RA. In vivo experiments showed that both BHGZT and BHGZT-GYP reduced the disease severity of AIA-H rats （P<0.01） by relieving joint redness and distortion， decreasing arthritis score and limb diameter， elevating pain thresholds， alleviating joint erosion， joint inflammation， and bone destruction （P<0.05）. Notably， BHGZT outperformed BHGZT-GYP （P<0.05）. Both BHGZT and BHGZT-GYP inhibited the pathological changes and decreased the indexes of thymus and spleen （P<0.05）， and down-regulated the expression of inflammatory cytokines including Toll-like receptor 4 （TLR4）， tumor necrosis factor-alpha （TNF-α）， interleukin-6 （IL-6）， IL-12， IL-1β， and IL-18 （P<0.05）. In addition， BHGZT and GYP significantly inhibited the adipogenic differentiation of 3T3-L1 cells， with the performance superior to that of BHGZT-GYP. ConclusionThe sovereign drug Gypsum Fibrosum contained in BHGZT played a crucial role in reversing energy metabolism disorders and immunity-inflammation imbalance， which may be associated with its cold property and function of clearing heat and purging fire.

ObjectiveTo systematically evaluate the safety of Chinese medicines combined with Tripterygium wilfordii polyglycoside tablets/Tripterygium wilfordii tablets （TWPT/TWT） in the treatment of rheumatoid arthritis （RA）， and to explore the network regulatory mechanisms of enhancing efficacy and reducing toxicity of commonly used combination regimes. MethodThe literature involving the adverse reactions of TWPT/TWT in treating RA was searched and collected from three Chinese databases （CNKI， Wanfang Data， VIP） and three English databases （PubMed， Cochrane Library， Embase） from the inception of the databases to July 2021. All studies were assessed by the Cochrane risk of bias tool， and the data were extracted and analyzed by Stata 15.0. Furthermore， Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine 2.0 （TCMIP v2.0，http：//www.tcmip.cn/） was used to construct a "drug target-symptom gene of efficacy and toxicity" interaction network， to explore the underlying network regulatory mechanisms of enhancing efficacy and reducing toxicity of common T. wilfordii preparation combinations. ResultA total of 2 132 articles on Chinese medicines combined with TWPT/TWT in the treatment of RA were retrieved， and 18 of them were finally included. The systematic review showed that the adverse reactions of TWPT/TWT against RA mainly occurred in the digestive system， blood system， and reproductive system， of which digestive system had the highest incidence of damages. However， the combination with Chinese medicines effectively alleviated the adverse reactions caused by TWPT/TWT ［RR （95% CI）=0.45 （0.30， 0.66）， P<0.01］. In addition， the subgroup analysis indicated that the age of RA patients， course of disease， combination regimen， medication dosage and duration of treatment all affected the occurrence of adverse reactions of TWPT/TWT. It was found in clinical studies that total glucosides of paeony （TGP） and TWPT/TWT was most widely combined， and the effect of TGP in reducing TWPT/TWT-induced hepatotoxicity was also more significant than that of other Chinese medicines. Moreover， taking this combination regime as an example， this paper explored the "efficacy-toxicity" association mechanisms of TGP-TWPT/TWT against RA. The "drug target-symptom gene of efficacy and toxicity" interaction network revealed that the core network targets of TGP-TWPT/TWT enhanced efficacy and reduced toxicity mainly through regulating immunity-inflammation-related pathways， metabolic pathways and cell signal transduction. Especially， interleukin-4 （IL-4） and interleukin-13 （IL-13）， which were involved in the "immunity-inflammation" module， were the common targets of TGP-TWPT/TWT to enhance efficacy and reduce toxicity. The endogenous sterols， bile acids and bile salts， insulin secretion and other metabolic pathways in the "body metabolism" module were closely associated with the mechanisms of TWPT/TWT inducing hepatotoxicity and TGP reducing hepatotoxicity. While cell function regulation pathways， such as stem cell factor （SCF）/tyrosine kinase receptor （KIT） signaling pathway and phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）signaling pathway were involved in both anti-RA effects and hepatotoxicity of TWPT/TWT. ConclusionClinical application of suitable Chinese medicines combined with TWPT/TWT in the treatment of RA can effectively improve the rheumatism and reduce the adverse reactions of TWPT/TWT， and TGP-TWPT/TWT has the most significant toxicity-reducing effect. Further biological network-based investigation indicates that the toxicity-reducing mechanism of TGP-TWPT/TWT may be related to the regulation of interleukin signaling pathway and bile acid metabolism pathway， and the synergistic efficacy-enhancing effect of the combination may be achieved by acting on interleukin signaling pathway and cell function regulation pathway.

ObjectiveTo explore the "efficacy-toxicity" association mechanisms of Tripterygium wilfordii polyglycoside tablets （TWPT） by establishing and analyzing an interaction network associated with the clinical efficacy of TWPT in the treatment of rheumatoid arthritis （RA） and TWPT-induced liver injury. MethodOn the basis of the TWPT efficacy-related gene expression profile and TWPT-induced liver injury-related protein expression profile which were both obtained from our clinical cohorts， the "efficacy-toxicity" association network of TWPT was constructed， and the key network targets were identified by calculating the topological values of the nodes， including the degree， closeness and betweenness. After that， the biological functions and pathways of the key network targets were investigated by enrichment analysis. ResultA total of 119 differentially expressed genes （58 up-regulated and 61 down-regulated） between RA patients with TWPT well and weak response were identified as TWPT efficacy-related genes by clinical transcriptomics， and 49 differentially expressed proteins （36 up-regulated and 13 down-regulated） were demonstrated to be TWPT-induced liver injury-related proteins by clinical proteomics. In addition， the clinical symptom enrichment analysis indicated that the TWPT efficacy-related genes were significantly associated with various clinical symptoms of arthralgia in traditional Chinese medicine and clinical phenotypes of modern medicine， and most of the TWPT-induced liver injury-related proteins were involved in digestive system abnormalities. Therefore， the aforementioned multi-omics data represented the main clinical symptoms of TWPT treating RA and inducing liver injury. Mechanically， the "efficacy-toxicity" association network revealed that both TWPT efficacy-related genes and TWPT-induced liver injury-related core proteins were involved in the "immune-inflammatory" imbalance， especially playing an important role in neutrophil degranulation， complement cascade reaction， and immune-inflammatory response mediated by protein post-translational modification. Notably， the above genes and proteins were also enriched in various signaling pathways related to cell proliferation and cell cycle regulation， such as RAS and mitogen-activated protein kinase （MAPK） signaling pathway， and in several liver functional processes， such as glycogen metabolism and redox reaction. ConclusionThis study systematically explained the "efficacy-toxicity" association characteristics and molecular mechanisms of TWPT by applying a research strategy integrating clinical phenomics， transcriptomics and proteomics， laying a good data foundation for exploring the "efficacy enhancing and toxicity-reducing" mechanisms of TWPT.
