RESUMEN
BACKGROUND: Sepsis causes inflammation in response to infection, often leading to acute lung injury (ALI). Yazhicao (Commelina communis L., YZC) is widely distributed in the global tropics and has good anti-respiratory inflammatory activity; however, the protection of YZC against septic-ALI has not been established. PURPOSE: The role of YZC in septic-ALI will be investigated in this study. METHODS AND RESULTS: In this study, YZC was shown to inhibit excessive inflammation and alleviate septic-ALI. Network pharmacology predicts that Quercetin, Acacetin and Diosmetin have the potential to serve as the pharmacological substance basis of YZC in alleviating septic-ALI. The metabolomics results indicated that YZC could improve the metabolic disorders caused by septic-ALI, which were mostly concerned with energy metabolism and amino acid metabolism, with Trimethylamine (TMA)/Trimethylamine N-oxide (TMAO) being potential small molecule metabolic markers for the clinical diagnosis and treatment of septic-ALI. YZC inhibits the initiation and progression of septic-ALI by controlling the TMA/TMAO metabolites. Our results also suggest that YZC protects the intestinal barrier from damage. Furthermore, our research indicated that YZC reduces TMAO synthesis by inhibiting TMA production through remodeling the intestine microbiota. We investigated the mechanism of YZC-mediated protection against septic-ALI and showed that YZC reduced the expression of proteins associated with NLRP3 inflammatory vesicles in the lung by inhibiting the expression of NF-κB. CONCLUSION: These results show that YZC inhibits the NF-κB/NLRP3 signaling pathway by regulating metabolic and intestinal flora disorders in septic-ALI mice to reduce TMAO synthesis. This study presents a theoretical groundwork for the advancement of novel medications and clinical use of YZC to enhance septic-ALI and furnishes a theoretical rationale for regulating intestinal microbiota as a therapeutic instrument to treat sepsis and septic-ALI.

Nephrogenic edema (NE) is a type of edema with hypoproteinemia and water and sodium retention as a result of renal injury. Traditional Chinese medicine has proved that Scrophularia ningpoensis Hemsl. has an effect on NE, but its mechanism is not clear. In this study, the main components and blood components of S. ningpoensis were identified using ultra-high-performance liquid chromatography-quadrupole-time-of-flight-mass spectrometry (UPLC-Q-TOF-MS). Pathological section and blood biochemical analysis were used to estimate the therapeutic effect of S. ningpoensis on NE. Network pharmacology was used to predict the potential pathways of S. ningpoensis. The metabolomics method was used to study the changes in small-molecule metabolites in the body. The results showed that S. ningpoensis could relieve NE by regulating relative to renal function and body edema, and its mechanism may be related to the regulation of energy metabolism, recovery of renal injury, and reduction in inflammation. The active component harpagoside may be one of the important compounds of S. ningpoensis in the treatment of NE. We confirmed that S. ningpoensis has a therapeutic effect on NE, which provides a solid scientific research basis for the clinical application of S. ningpoensis.

ETHNOPHARMACOLOGICAL RELEVANCE: Acute lung injury (ALI) is a life-threatening condition with high morbidity and mortality, underscoring the urgent need for novel treatments. Monochasma savatieri Franch. (LRC) is commonly used clinically to treat wind-heat cold, bronchitis, acute pneumonia and acute gastroenteritis. However, its role in the treatment of ALI and its mechanism of action are still unclear. AIM OF THE STUDY: This study aimed to demonstrate the pharmacological effects and underlying mechanisms of LRC extract, and provide important therapeutic strategies and theoretical basis for ALI. MATERIALS AND METHODS: In this study, a research paradigm of integrated pharmacology combining histopathological analysis, network pharmacology, metabolomics, and biochemical assays was used to elucidate the mechanisms underlaying the effects of LRC extract on LPS-induced ALI in BALB/c mice. RESULTS: The research findings demonstrated that LRC extract significantly alleviated pathological damage in lung tissues and inhibited apoptosis in alveolar epithelial cells, and the main active components were luteolin, isoacteoside, and aucubin. Lung tissue metabolomic and immunohistochemical methods confirmed that LRC extract could restore metabolic disorders in ALI mice by correcting energy metabolism imbalance, activating cholinergic anti-inflammatory pathway (CAP), and inhibiting TLR4/NF-κB signaling pathway. CONCLUSIONS: This study showed that LRC extract inhibited the occurrence and development of ALI inflammation by promoting the synthesis of antioxidant metabolites, balancing energy metabolism, activating CAP and suppressing the α7nAChR-TLR4/NF-κB p65 signaling pathway. In addition, our study provided an innovative research model for exploring the effective ingredients and mechanisms of traditional Chinese medicine. To the best of our knowledge, this is the first report describing the protective effects of LRC extract in LPS-induced ALI mice.

ETHNOPHARMACOLOGICAL RELEVANCE: Based on the theory of traditional Chinese medicine (TCM), diabetic cardiomyopathy (DCM) belongs to the category of "Xiaoke disease" according to the symptoms, and "stasis-heat" is the main pathogenesis of DCM. The Chinese medicine Anemarrhena asphodeloides Bunge (AAB), as a representative of heat-clearing and engendering fluid, is often used clinically in the treatment of DCM. Anemarrhena asphodeloides Bunge total saponins (RATS) are the main bioactive components of AAB, the modern pharmacologic effects of RATS are anti-inflammatory, hypoglycemic, and cardioprotective. However, the potential protective mechanisms of RATS against DCM remain largely undiscovered. AIM OF THE STUDY: The primary goal of this study was to explore the effect of RATS on DCM and its mechanism of action. MATERIALS AND METHODS: Streptozotocin and a high-fat diet were used to induce DCM in rats. UHPLC/Q-TOF-MS was used to determine the chemical components of RATS. The degenerative alterations and apoptotic cells in the heart were assessed by HE staining and TUNEL. Network pharmacology was used to anticipate the probable targets and important pathways of RATS. The alterations in metabolites and main metabolic pathways in heart tissue were discovered using 1 H-NMR metabolomics. Ultimately, immunohistochemistry was used to find critical pathway protein expression. RESULTS: First of all, UHPLC/Q-TOF-MS analysis showed that RATS contained 11 active ingredients. In animal experiments, we found that RATS lowered blood glucose and lipid levels in DCM rats, and alleviated cardiac pathological damage, and decreased cardiomyocyte apoptosis. Furthermore, the study found that RATS effectively reduced inflammatory factor release and the level of oxidative stress. Mechanistically, RATS downregulated the expression levels of PI3K, AKT, HIF-1α, LDHA, and GLUT4 proteins. Additionally, glycolysis was discovered to be a crucial pathway for RATS in the therapy of DCM. CONCLUSIONS: Our findings suggest that the protective effect of RATS on DCM may be attributed to the inhibition of the PI3K/AKT/HIF-1α pathway and the correction of glycolytic metabolism.

Aging is a degenerative progress, accompanied by oxidative damage, metabolic disorders and intestinal flora imbalance. Natural macromolecular polysaccharides have shown excellent anti-aging and antioxidant properties, while maintaining metabolic and intestinal homeostasis. The molecular weight, monosaccharide composition, infrared spectrum and other chemical structure information of four Rehmannia glutinosa polysaccharides (RG50, RG70, RG90, RGB) were determined, and their free radical scavenging ability was assessed. Molecular weight and monosaccharide composition analysis exhibited that RG50 (2-72 kDa), RG70 (3.2-37 kDa), RG70 (3-42 kDa), and RGB (3.1-180 kDa) were heteropolysaccharide with significant different monosaccharide species and molar ratios. We found that RG70 had the best antioxidant activity in vitro and RG70 could enhance the antioxidant enzyme system of Caenorhabditis elegans, diminished lipofuscin and reactive oxygen species levels, up-regulate the expression of daf-16, skn-1 and their downstream genes, and down-regulate the expression of age-1. Metabolomics results showed that RG70 mainly influenced glycine, serine and threonine metabolism and citric acid cycle. 16S rRNA sequencing showed that RG70 significantly up-regulated the abundance of Lachnospiraceae_NK4B4_group, which were positively correlated with amino acid metabolism and energy cycling. These results suggest that RG70 may delay aging by enhancing antioxidant effects, affecting probiotics and regulating key metabolic pathways.

ETHNOPHARMACOLOGICAL RELEVANCE: Coptis chinensis Franch. (CCF), as an extensively used traditional Chinese medicine, has therapeutic effects on Alzheimer's disease (AD), but its mechanism of action has not yet been elucidated. AIM OF THE STUDY: This study aims to reveal the mechanism of action of CCF via the gut-brain axis, and provide a new strategy for the clinical treatment of AD. MATERIALS AND METHODS: APPswe/PS1ΔE9 mice were used as AD models, and were given CCF extract by intragastric administration. Barnes maze was used to test the therapeutic effect of CCF on the treatment of AD. To reveal the mechanism of action of CCF in the treatment of AD, Vanquish Flex UHPLC-orbitrap fusion lumos mass was chosen to detect endogenous differential metabolite; MetaboAnalyst 5.0 was applied to derive relevant metabolic pathways; similarly, to explore the effects of CCF on the gut-brain axis, Vanquish Flex UPLC-Orbitrap fusion lumos mass was utilized to detect the changes in the content of SCFAs in AD mice after CCF administration; the prototype components and metabolites in CCF were identified by UPLC/ESI/qTOF-MS, then their effects on Bifidobacterium breve were explored. RESULTS: CCF shortened the latency time of AD mice, improved the target quadrant ratio of AD mice, and made the maze roadmap simpler of AD mice; CCF regulated fifteen potential metabolites of AD mice, interestingly, ILA (indole-3-lactic acid) in SCFAs (short-chain fatty acids) was also included; CCF acted on histidine and phenylalanine metabolic pathways of AD mice; CCF increased the contents of acetic acid and ILA in AD mice; magnoflorine, jatrorrhizine, coptisine, groenlandicine, thalifendine, palmatine, berberine, epiberberine, hydroxylated jatrorrhizine, and 3-methoxydemethyleneberberine in CCF were detected in fecal samples of AD mice; magnoflorine, palmatrubine, 13-methylberberine, berberine, coptisine, and palmatine promoted the growth of Bifidobacterium breve. CONCLUSIONS: we have demonstrated that CCF acts on the gut-brain axis by regulating SCFAs to treat AD.

Atopic dermatitis (AD) is a common, chronic, and recurring inflammatory skin disease. Physalis alkekengi L. var. franchetii (Mast) Makino (PAF), a traditional Chinese medicine, is primarily used for the clinical treatment of AD. In this study, a 2,4-dinitrochlorobenzene-induced AD BALB/c mouse model was established, and a comprehensive pharmacological method was used to determine the pharmacological effects and molecular mechanisms of PAF in the treatment of AD. The results indicated that both PAF gel (PAFG) and PAFG+MF (mometasone furoate) attenuated the severity of AD and reduced the infiltration of eosinophils and mast cells in the skin. Serum metabolomics showed that PAFG combined with MF administration exerted a synergistic effect by remodeling metabolic disorders in mice. In addition, PAFG also alleviated the side effects of thymic atrophy and growth inhibition induced by MF. Network pharmacology predicted that the active ingredients of PAF were flavonoids and exerted therapeutic effects through anti-inflammatory effects. Finally, immunohistochemical analysis confirmed that PAFG inhibited the inflammatory response through the ERß/HIF-1α/VEGF signaling pathway. Our results revealed that PAF can be used as a natural-source drug with good development prospects for the clinical treatment of AD.

ETHNOPHARMACOLOGICAL RELEVANCE: Chronic obstructive pulmonary disease (COPD) is the third leading cause of death globally and thus imposes heavy economic burden on patients, their families, and society. Furthermore, COPD seriously affects the quality of life of patients. The concept of "overall regulation" of traditional Chinese medicine (TCM) plays an important role in the prevention and treatment of COPD. AIM OF THE STUDY: The objective of this review is to summarize the TCM theories, experimental methods, TCM extracts, active TCM ingredients, and TCM formulas for the treatment of COPD and reveal the effects and mechanisms of TCM treatments on COPD. MATERIALS AND METHODS: This article reviewed literature on TCM-based treatments for COPD reported from 2016 to 2021. Relevant scientific studies were obtained from databases that included PubMed, China National Knowledge Infrastructure, Web of Science, Google Scholar, The Plant List, ScienceDirect, and SciFinder. RESULTS: This review summarized TCM-based theory, experimental methods, active ingredients, and potential toxicities, the effects of TCM extracts and formulations, and their mechanisms for the treatment of COPD. Most investigators have used in vivo models of cigarette smoke combined with lipopolysaccharide induction in rats and in vitro models of cigarette smoke extract induction. The active ingredients of TCM used for the treatment of COPD in relevant studies were triterpenoids, flavonoids, phenolics, quinones, glycosides, and alkaloids. TCMs commonly used in the treatment of COPD include antipyretic drugs, tonic medicines, anticough medications, and asthma medications. TCM can treat COPD by suppressing inflammation, reducing oxidative stress, inhibiting apoptosis, and improving airway remodeling. CONCLUSIONS: This review enriches the theory of COPD treatments based on TCM, established the clinical significance and development prospects of TCM-based COPD treatments, and provided the necessary theoretical support for the further development of TCM resources for the treatment of COPD.

Considering that natural polysaccharides are potential anti-inflammatory agents, in this study, an arabinan (RGP70-2) was isolated and purified from Rehmannia glutinosa Libosch. (R. glutinosa) and its structure was characterized. RGP70-2 was a homogeneous polysaccharide with a molecular weight of 6.7 kDa, with the main backbone comprising â5)-α-L-Araf-(1â, â3)-α-L-Araf-(1â, â2,3,5)-α-L-Araf-(1â, and â2,5)-α-L-Araf-(1 â linkages and the side chain comprising an α-L-Araf-(1 â linkage. In vivo experiments showed that RGP70-2 inhibited ROS production and downregulated the expression of pro-inflammatory cytokines (TNF-α, IL-1ß, and IL-6). In vitro experiments showed that RGP70-2 decreased levels of pro-inflammatory cytokines, inhibited ROS production, and attenuated NF-κB-p65 translocation from the cytoplasm to the nucleus. Our results showed that RGP70-2 may delay inflammation by regulating the ROS-NF-κB pathway. Thus, RGP70-2 has potential applications as an anti-inflammatory agent in the biopharmaceutical industry.

BACKGROUND: Acute lung injury (ALI) is a serious health issue which causes significant morbidity and mortality. Inflammation is an important factor in the pathogenesis of ALI. Even though ALI has been successfully managed using a traditiomal Chinese medicine (TCM), Huanglian Jiedu Decoction (HLD), its mechanism of action remains unknown. PURPOSE: This study explored the therapeutic potential of HLD in lipopolysaccharide (LPS)-induced ALI rats by utilizing integrative pharmacology. METHODS: Here, the therapeutic efficacy of HLD was evaluated using lung wet/dry weight ratio (W/D), myeloperoxide (MPO) activity, and levels of tumor necrosis factor (TNF-α), interleukin (IL)-1ß and IL-6. Network pharmacology predictd the active components of HLD in ALI. Lung tissues were subjected to perform Hematoxylin-eosin (H&E) staining, metabolomics, and transcriptomics. The acid ceramidase (ASAH1) inhibitor, carmofur, was employedto suppress the sphingolipid signaling pathway. RESULTS: HLD reduced pulmonary edema and vascular permeability, and suppressed the levels of TNF-α, IL-6, and IL-1ß in lung tissue, Bronchoalveolar lavage fluid (BALF), and serum. Network pharmacology combined with transcriptomics and metabolomics showed that sphingolipid signaling was the main regulatory pathway for HLD to ameliorate ALI, as confirmed by immunohistochemical analysis. Then, we reverse verified that the sphingolipid signaling pathway was the main pathway involed in ALI. Finally, berberine, baicalein, obacunone, and geniposide were docked with acid ceramidase to further explore the mechanisms of interaction between the compound and protein. CONCLUSION: HLD does have a better therapeutic effect on ALI, and its molecular mechanism is better elucidated from the whole, which is to balance lipid metabolism, energy metabolism and amino acid metabolism, and inhibit NLRP3 inflammasome activation by regulating the sphingolipid pathway. Therefore, HLD and its active components can be used to develop new therapies for ALI and provide a new model for exploring complex TCM systems for treating ALI.

Influenza virus-induced pneumonia (IVP) is a high morbidity and contagiousness pulmonary infectious disease caused by invasion of the influenza virus into the lower respiratory tract. Currently, the treatment of IVP is mainly based on an anti-influenza virus infection strategy, which includes the use of anti-influenza vaccines and drugs. However, the clinical use of these treatment options is limited as the influenza virus has a high level of variability and drug resistance may occur. Traditional Chinese medicines (TCMs) for the treatment of IVP have unique advantages, a variety of precise curative effects and have been widely used in clinical practice in China both historically and in the present day. However, there are only few literature reviews on the prevention and treatment of IVP using TCMs. Therefore, we conducted a review of relevant literature from the past 10 years and a comprehensive analysis of various databases containing reports on TCMs used for IVP prevention and treatment to provide basic data for future research and development of drugs against IVP. Herein, we summarize research progress on the pathogenesis of IVP, the TCMs effective in prevention or treatment of IVP, their underlying molecular mechanisms and active components. Overall, we provide a theoretical basis for the clinical use of TCM in the prevention and treatment of IVP. Furthermore, we provide a reference for the development of new multi-component, multi-target, low-toxicity drugs, which is of great academic and clinical significance.

ETHNOPHARMACOLOGICAL RELEVANCE: Erzhi Pill (EZP) is a traditional Chinese prescription that has marked effects in treating type 2 diabetes mellitus and diabetic nephropathy. However, its underlying pharmacological mechanisms in the treatment of diabetic cardiomyopathy (DCM), remain to be elucidated. AIM OF THE STUDY: This study aimed to apply an integrative pharmacological strategy to systematically evaluate the pharmacological effects and molecular mechanisms of EZP, and provide a solid theoretical basis for the clinical application of EZP in the treatment of DCM. MATERIALS AND METHODS: In this study, the potential targets and key pathways of EZP were predicted and validated using network pharmacology and molecular docking, respectively. Changes in cardiac metabolites and major metabolic pathways in rat heart samples were examined using 1H-nuclear magnetic resonance (NMR) metabolomics. Finally, biochemical analysis was conducted to detect the protein expression levels of key pathways. RESULTS: We found that EZP decreased fasting blood glucose (FBG), triglycerides (TG), total cholesterol (TC), and low-density lipoprotein (LDL) levels, increased high-density lipoprotein (HDL) levels in the serum, and alleviated the morphological abnormalities of the heart tissue in diabetic rats. Furthermore, EZP effectively restored superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), caspase-3, caspase-8, and caspase-9 activity levels, as well as the levels of reactive oxygen species (ROS), malondialdehyde (MDA), B-cell lymphoma (Bcl)-2, and Bcl-2-associated X protein (Bax) in the heart tissue. Network pharmacology prediction results indicated that the mechanism of EZP in treating DCM was closely related to apoptosis, oxidative stress, and the HIF-1, PI3K-Akt, and FoxO signaling pathways. In addition, 1H-NMR metabolomics confirmed that EZP primarily regulated both energy metabolism and amino acid metabolism, including the tricarboxylic acid (TCA) cycle, ketone bodies metabolism, glutamine and glutamate metabolism, glycine metabolism, and purine metabolism. Finally, immunohistochemistry results indicated that EZP reduced the expression levels of p-AMPK, p-PI3K, p-Akt, and p-FoxO3a proteins, in the heart tissue of DCM rats. CONCLUSION: The results confirmed that the overall therapeutic effect of EZP in the DCM rat model is exerted via inhibition of oxidative stress and apoptosis, alongside the regulation of energy metabolism and amino acid metabolism, as well as the AMPK and PI3K/Akt/FoxO3a signaling pathways. This study provides an experimental basis for the use of EZP in DCM treatment.

ALI is a severe inflammatory disease of the lungs. In previous studies, we found that GQD was effective against ALI, but specific molecular mechanism is still unclear. Therefore, this study was to examine effect of GQD on LPS-induced ALI rats and underlying mechanisms using multi-omics and molecular methods. The results showed that GQD significantly improved lung tissue damage, reduced pulmonary edema, inhibited MPO activity, and improved respiratory function in ALI rat. Additionally, GQD significantly reduced the levels of TNF-α, IL-1ß, and IL-6 in serum and BALF. Furthermore, metabolomic analysis showed that GQD reduced pulmonary inflammation by improving metabolic remodeling. Moreover, transcriptomic analysis showed that GQD inhibited the activation of complement pathway and regulated Th17 and Treg cells balance. Additionally, GQD inhibited the expression of C3, C5a, and IL-17, and promoted the expression of TGF-ß and CYP1A1 at the mRNA and protein levels. Gut microbial assay showed that GQD treatment increased the relative abundance of Firmicutes and their genera in intestinal microbiota, and increased short-chain fatty acids concentration. Overall, GQD treated ALI by improving metabolic remodeling, affecting immune-related pathways and regulating intestinal microbiota. This study provides a solid scientific basis for promoting the clinical use of GQD in treating ALI.
RESUMEN
As a traditional Chinese medicine, Dalbergia tsoi Merr.et Chun (JZX) has been used for the treatment of wounds since ancient times. However, the active compounds and molecular mechanisms of JZX in the acceleration of wound healing are still unknown. Herein, we explored the main active compounds and key molecular mechanisms by which JZX accelerates wound healing. The ethanol extract of JZX was subjected to UPLC-Q-Orbitrap HRMS analysis to identify the main compounds. The pharmacological effect of JZX on wound healing was evaluated using a mouse excision wound model. Network pharmacology was utilized to predict the effective compounds and related signal transduction pathways of JZX that were involved in accelerating wound healing. The predicted key signaling pathways were then validated by immunohistochemical analysis. Interactions between the active compounds and therapeutic targets were confirmed by molecular docking analysis. JZX accelerated wound healing, improved tissue quality, and inhibited inflammation and oxidative stress. Moreover, our results suggested that the active components of JZX, such as butin, eriodyctiol, and formononetin, are the key compounds that facilitate wound treatment. Our studies also indicated that JZX accelerated wound healing by regulating the PI3K/Akt signaling pathway and inducing the expression of TGF-ß1, FGF2, VEGFA, ECM1, and α-SMA at different stages of skin wound healing. The JZX extract accelerates wound healing by reducing inflammation and inhibiting oxidative stress, regulating the PI3K/Akt signaling pathway, and promoting the expression of growth factors, suggesting that JZX has potential clinical applicability in wound treatment.

ETHNOPHARMACOLOGICAL RELEVANCE: Physalin B (PB) is an active constituent of Physalis alkekengi L. var. Franchetii, which is a traditional medicine for clearing heat and detoxification, resolving phlegm, and diuresis. It has been commonly applied to treat sore throat, phlegm-heat, cough, dysuria, pemphigus, and eczema. AIM OF STUDY: Physalin B has shown efficacy as an anti-acute lung injury (ALI) agent previously; however, its mechanisms of action remain unclear. In the present study, we established a lipopolysaccharide-induced septic ALI model using BALB/c mice to further confirm the therapeutic potential of PB and to assess the underlying molecular mechanisms. MATERIALS AND METHODS: We used 75% ethanol and macroporous resin for extraction, separation, and enrichment of PB. The LPS-induced ALI mouse model was used to determine anti-inflammatory effects of PB. The severity of acute lung injury was evaluated by hematoxylin and eosin staining, wet/dry lung ratio, and myeloperoxidase (MPO) activity in lung tissue. An automatic analyzer was used to measure the arterial blood gas index. Protein levels of pro-inflammatory cytokines in serum, bronchoalveolar lavage fluid (BALF), and lung tissue was measured using an ELISA. Quantitative RT-PCR was used to measure changes in RNA levels of pro-inflammatory cytokines in the lungs. A fluorometric assay kit was used for determination of apoptosis-related factors to assess anti-apoptotic effects of PB. Western blotting was used to assess levels of key pathway proteins and apoptosis-related proteins. Connections between the pathways were tested through inhibitor experiments. RESULTS: Pretreatment with PB (15 mg kg-1 d-1, i.g.) significantly reduced lung wet/dry weight ratios and MPO activity in blood and BALF of ALI mice, and it alleviated LPS-induced inflammatory cell infiltration in lung tissue. The levels of pro-inflammatory factors TNF-α, IL-6, and IL-1ß and their mRNA levels in blood, BALF, and lung tissue were reduced following PB pretreatment. PB pretreatment also downregulated the apoptotic factors caspase-3, caspase-9, and apoptotic protein Bax, and it upregulated apoptotic protein Bcl-2. The NF-κB and NLRP3 pathways were inhibited through activation of the PI3K/Akt pathway due to PB pretreatment, whereas administration of PI3K inhibitors increased activation of these pathways. CONCLUSIONS: Taken together, our results suggest that the anti-ALI properties of PB are closely associated with the inactivation of NF-κB and NLRP3 by altering the PI3K/Akt pathway. Furthermore, our findings provide a novel strategy for application of PB as a potential agent for treating patients with ALI. To the best of our knowledge, this is the first study to elucidate the underlying mechanism of action of PB against ALI.

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease. Bu-Shen-Tong-Du prescription (BSP) has traditionally been used in to treat RA but its underlying mechanisms remain unclear. In this study, we explored the potential mechanisms of BSP in collagen-induced arthritis (CIA) rats, a classic animal model of RA. We employed an integrated pharmacology approach in combination with network pharmacology, 1H-nuclear magnetic resonance (NMR) metabolomics, and biochemical analyses to determine the mechanisms of BSP for treating RA. We found that BSP can regulate immunity and inflammation by decreasing the spleen index; inhibiting hyperplasia of the white pulp; reducing the levels of IL-1ß, IL-6, IL-17A, and IFN-γ; and increasing the levels of IL-10 in the serum. Network pharmacology was utilized to predict related signal transduction pathways of BSP in RA treatment. 1H NMR metabolomics of the serum confirmed that BSP regulated energy metabolism and amino acid metabolism. Finally, we validated the Toll-like receptor 4 (TLR4)/nuclear factor (NF)-κB signaling pathway using immunohistochemical methods, which demonstrated that BSP controlled RA-induced inflammation by inhibiting the TLR4/NF-κB signaling pathway. These results confirm the therapeutic effect of BSP in a CIA rat model, which is exerted via the inhibition of the inflammation and the improvement of the immune function, balancing energy metabolism and amino acid metabolism, and inhibiting the TLR4/NF-κB signaling pathway. This study provides an experimental basis for using BSP as a combinatorial drug to inhibit inflammation and regulate immunity in the treatment of RA.

Two new hexenol glycosides, (Z)-hex-3-en-1-ol O-ß-d-xylcopyranosyl-(1-6)-ß -d-glucopyranosyl-(1-2)-ß-d-glucopyranoside (1) and (E)-hex-3-en-1-ol O-ß-d-xylcopyranosyl-(1-6)-ß-d-glucopyranosyl-(1-2)-ß-d-glucopyranoside (2), were isolated from the 50% ethanol elution of macroporous resin of Physalis alkekengi var. franchetii. Their structures were established by detailed spectroscopic analysis, including extensive 2D-NMR data. This is the first time to report the (Z) and (E) 3-hexenol glycosides from Physalis alkekengi var. franchetii.
