Ethnopharmacological relevance Recurrent or persistent respiratory tract infection may progress to chronic pneumonia or other debilitating sequelae in the absence of appropriate therapeutic interventions, seriously compromising the patients' quality of life. LianZhiXiaoYan Formula (LZXYF), a Chinese prescription composed of Chinese medical herbs Andrographis herba (ChuanXinLian) and Radix helicteris (ShanZhiMa), possesses efficiency of clearing heat and detoxifying, and shown a good therapeutic effect on respiratory infectious diseases, but its mechanism of action is not clear. Aim of the study Aim to evaluate the therapeutic efficacy of LZXYF in treatment of CP and investigate its molecular and physiological mechanisms. Materials and methods The therapeutic effects of LZXYF on CP was evaluated in an LPS-induced murine model by assessing the pulmonary function, lung histopathology, and biochemical indicators. To explore the mechanism of LZXYF, the lung metabolomics and the components of LZXYF distributed in lung were analyzed by UHPLC-Q-TOF-MS/MS. The impact of LZXYF on SIRT3-SDH-SCUNR1 pathway was investigated using RT-qPCR and Western blot, and the interaction between LZXYF and SIRT3 was verified via CETSA. LPS-induced LLC cell and succinate-induced RAW264.7 cell were employed to investigate the effect and mechanism of LZXYF on metabolic reprogramming and inflammation regulation, with selective inhibition of SIRT3 and SUCNR1, respectively. Results LZXYF treatment improved pulmonary function as demonstrated by increased Tidal volume, enhanced Minute ventilation, elevated Peak expiratory flow rate, and reduced Timed inspiration ( P < 0.05). Moreover, histopathological analysis revealed that LZXYF treatment attenuated emphysema and airway remodeling, concomitant with reduced the levels of TGF-β and HYP ( P < 0.01). Metabolomics demonstrated that LZXYF treatment restored 38 dysregulated metabolites in CP mice, primarily involving tryptophan, histidine, lysine and arginine metabolic pathways. Correlation analysis of 16 lung-distributed components and the 38 differential metabolites further indicated that LZXYF alleviated CP through SIRT3 signaling pathway mediated metabolic reprogramming. We further demonstrated that LZXYF could up-regulate SIRT3 to enhance the activities of SDH ( P < 0.01), a metabolic enzyme in TCA cycle, thereby regulating metabolic reprogramming and inhibiting the activation of SUCNR1 to prevent succinate-induced inflammation responses ( P < 0.01). Furthermore, we elucidated that the active components of LZXYF exerted ameliorated effects by up-regulating SIRT3 expression in LPS or 3-TYP induced LLC cell metabolic reprogramming, which revealed SIRT3 as a critical molecular target for LZXYF to improve metabolic reprogramming and suppress inflammatory responses induced by succinate. Conclusion LXZYF could ameliorate CP through up-regulating SIRT3, which enhances TCA cycle and suppresses succinate-mediated inflammation. This study provides new insight into the therapeutic potential of LZXYF for CP treatment.

The risk of the illegal addition of anti-inflammatory and analgesic chemical drugs in anti-rheumatic health foods should not be ignored. Market supervision and rapid on-site detection technology need to be strengthened. Thin-layer chromatography-surface-enhanced Raman spectroscopy (TLC-SERS), which has the advantages of simple operation, fast separation, and qualitative and quantitative detection, was used in this study. And these eleven chemical drugs (acetaminophen, acetylsalicylic acid, aminophenazone, dexamethasone , diclofenac sodium , hydrocortisone, indometacin, naproxen, phenylbutazone, piroxicam , prednisone 21-acetate) that may be added to anti-rheumatic health foods have been simultaneously identified by TLC-SERS combined with chemometrics method. The characteristic signals of the separated drug spots were collected by SERS, which were optimized by the gold colloidal nanoparticles' volume and integration time. Then SERS was subjected to principal component analysis (PCA) to reduce dimensionality and combined with the pattern recognition methods in chemometrics, such as PCA-Linear Discriminant Analysis (LDA), PCA-K Nearest Neighbor and PCA-Support Vector Machine, and eleven drug components were judged and identified. Moreover, the predictive performances of different models were also analyzed and compared. The results showed that the TLC plate and four organic solvents of petroleum ether, chloroform , ethyl acetate and acetic acid were selected as the developing agent. The dropping amount of gold colloidal nanoparticles and the integration time were set and optimized. The limit of detection of the simultaneous detection method of SERS was 10–100 mg/L. Furthermore, SERS was preprocessed by Gap-Segment 2nd Derivative, and then the PCA-LDA model was established, and the model's prediction accuracy can reach 100%. The method is simple, rapid, sensitive and accurate, and has low experimental instruments and equipment requirements. It is suitable for the on-site simultaneous detection of various anti-inflammatory and analgesic chemical drugs in health foods. It can also provide guarantee and support for the establishment of appropriate rapid detection methods and the development of supervision technology.

Ethnopharmacological relevance Pudilan Xiaoyan Oral Liquid (PDL) is a proprietary Chinese medicinal preparation approved by the State for treating acute pharyngitis in both adults and children (Approval No. Z20030095). It is worth noting that children exhibit unique physiopathological characteristics compared to adults. However, the in vivo regulatory characteristics of PDL in treating acute pharyngitis in children remain incompletely understood. Aim of the study The differential absorption and metabolism characteristics of the main pharmacological components in PDL in young and adult rats were investigated with a view to providing a reference for preclinical data of PDL in medication for children. Materials and Methods This study utilized UPLC-Q-TOF-MS to investigate the pharmacodynamic material basis of PDL. The focus was on the gastrointestinal digestion and absorption characteristics of organic acid components in PDL (PDL-OAC), known as the primary pharmacodynamic components in this formulation. The research combined in vitro dynamic simulation and a Quadruple single-pass intestinal perfusion model to examine these characteristics. The permeability properties of PDL-OAC were evaluated using an artificial parallel membrane model. Additionally, an acute pharyngitis model was established to evaluate the histopathological condition of the pharynx in young rats using H&E staining. The levels of IL-1 β , TNF- α , IL-6, and IL-10 in blood and pharyngeal tissue homogenates of young rats were quantified using ELISA kits. Results A total of 91 components were identified in PDL, including 33 organic acids, 24 flavonoids, 14 alkaloids, 5 terpenoids and coumarins, 3 sugars, and 12 amino acids. The PDL-OAC exhibited a significant reduction in IL-1 β , TNF- α , IL-6, and IL-10 levels in the pharyngeal tissues of young rats with acute pharyngitis. Results from dynamic simulation studies of gastrointestinal fluids revealed that the PDL-OAC (Specifically chlorogenic acid (CGA), gallic acid (GA), chicoric acid (CRA), and caffeic acid (CA)) were effectively stabilized in the gastrointestinal fluids of both children and adults in vitro . Young rats, characterized by thinner intestinal walls and higher permeability, efficiently absorbed the four organic acids across the entire intestinal segment. The absorption of CGA, GA, and CRA followed a concentration-dependent pattern, with CGA and GA absorption being influenced by exocytosis. Conclusion The efficacy of the PDL-OAC in treating acute pharyngitis was demonstrated in young rats. The absorption rate of these components was observed to be faster in young rats compared to adult rats, underscoring the need for dedicated studies on the drug's usage in children. This research provides valuable insights for the appropriate clinical use of PDL in pediatric patients.

Ethnopharmacological relevance The well-known Chinese prescription, Xiaoyan Lidan Formula (XYLDF), possesses efficiency of heat-clearing, dampness-eliminating and jaundice-removing. It has long been used clinically for the treatment of hepatobiliary diseases due to intrahepatic cholestasis (IHC). However, the mechanism of XYLDF for its therapeutic effects remains elusive. Aim of the study The study aimed to explore the potential targets for liver protective mechanism of XYLDF based on network pharmacology and experimental assays in ANIT-induced cholestatic hepatic injury (CHI) in rats. Materials and methods On the basis of the 29 serum migrant compounds of XYLDF elucidated by UPLC-TOF-MS/MS, a network pharmacology approach was applied for the mechanism prediction. Systematic networks were constructed to identify potential molecular targets, biological processes, and signaling pathways. And the interactions between significantly potential targets and active compounds were simulated by molecular docking. For the mechanism validation, an ANIT-induced rat model was used to evaluate the effects of XYLDF on CHI according to serum biochemistry, bile flow rates, histopathological examination, and the gene and protein expression including enzymes related to synthesis, export, and import of bile acid in liver and ileum, and those of inflammatory cytokines, analyzed by RT-qPCR and WB. Results The results of network pharmacology research indicated TNF (TNF-α), RELA (NF-κB), NR1H4 (FXR), and ICAM1 (ICAM-1) to be the important potential targets of XYLDF for cholestatic liver injury, which are related to bile metabolism and NF-κB-mediated inflammatory signaling. And the molecular docking had pre-validated the prediction of network pharmacology, as the core active compounds of XYLDF had shown strong simulation binding affinity with FXR , followed by NF-κB, TNF-α, and ICAM-1. Meanwhile, the effects of XYLDF after oral administration on ANIT-induced CHI in rats exhibited the decreased levels of transaminases (ALT and AST), TBA, and TBIL in serum, raised bile flow rates, and markedly improved hepatic histopathology. Furthermore, consistent to the above targets prediction and molecular docking, XYLDF significantly up-regulated the expression of FXR, SHP, BSEP, and MRP2 , and down-regulated CYP7A1 and NTCP in liver, and promoted expression of IBABP and OSTα/β in ileum, suggesting the activation of FXR-mediated pathway referring to bile acid synthesis, transportation, and reabsorption. Moreover, the lower levels of TNF-α in plasma and liver, as well as the reduced hepatic gene and protein expression of NF-κB, TNF-α, and ICAM-1 after XYLDF treatment revealed the suppression of NF-κB-mediated inflammatory signaling pathway, as evidenced by the inhibition of nuclear translocation of NF-κB. Conclusions XYLDF exhibited an ameliorative liver protective effect on ANIT-induced cholestatic hepatic injury. The present study has confirmed its mechanism as activating the FXR-regulated bile acid pathway and inhibiting inflammation via the NF-κB signaling pathway.

Background Pudilan Xiaoyan Oral Liquid (PDL) is a famous traditional Chinese prescription recorded in the Chinese Pharmacopeia, which is widely used to treat inflammatory diseases of the respiratory tract in children and adults. However, the endogenous changes in children and adults with PDL in the treatment of acute pharyngitis remain unclear. Purpose The differential regulatory roles of PDL in endogenous metabolism and gut microbes in young and adult rats were investigated with a view to providing a preclinical data reference for PDL in medication for children. Methods An acute pharyngitis model was established, and serum levels of inflammatory factors and histopathology were measured. This study simulated the growth and development of children in young rats and explored the endogenous metabolic characteristics and intestinal microbial composition after the intervention of PDL by using serum metabolomic technique and 16S rRNA high-throughput sequencing technique. Results The results showed that PDL had therapeutic effects on young and adult rats with acute pharyngitis. Sixteen biomarkers were identified by metabolomics in the serum of young rats and 23 in adult rats. PDL can also affect intestinal microbial diversity and community richness in young and adult rats. Alloprevotella, Allobaculum, Alistipes, Bifidobacterium , and Enterorhabdus were prominent bacteria in young rats. Bacteria from the phylum Firmicutes of the adult rats changed more significantly under the treatment of PDL. In young rats, amino acid metabolism was the primary regulatory mode of PDL, whereas, in adult rats, glycerophospholipid metabolism was studied. Conclusion The regulation of PDL on the serum metabolite group and intestinal microflora in young rats was different from that in adult rats, indicating the necessity of an independent study on children's medication. PDL may also exert therapeutic effects on young and adult rats by regulating gut microbial homeostasis. The results support the clinical application of PDL.

Xiaoyankangjun tablet (XYKJP) is a traditional Chinese medicine formulation used to treat intestinal disorders in clinical practice. However, the specific therapeutic mechanism of action of XYKJP in colitis has not yet been elucidated. This study aimed to reveal the multifaceted mechanisms of action of XYKJP in treating colitis. The model established based on DSS-induced colitis in C57BL/6 mice was employed to estimate the effect of XYKJP on colitis, which was then followed by histological assessment, 16S rRNA sequencing, RT-qPCR, ELISA, and Western blot. XYKJP alleviated the symptoms of DSS-induced colitis mainly by reducing oxidative stress, inflammatory responses, and intestinal mucosal repair in colitis tissues. In addition, XYKJP regulated the intestinal flora by increasing the relative abundance of Akkermansia and Bifidobacterium and reducing the relative abundance of Coriobacteriaceae_UCG-002 . Mechanistically, XYKJP increased the content of short-chain fatty acids (SCFAs) in the feces, particularly propanoic acid and butyric acid, activated their specific receptor GPR43/41, furthermore activated the Nrf2/HO-1 pathway, and suppressed the JAK2/STAT3 pathway. XYKJP significantly alleviated the symptoms of experimental colitis and functioned synergistically by regulating the intestinal flora, increasing the production of SCFAs, and activating their specific receptors, thereby repressing oxidative stress and inflammation.

Objective: Allergic asthma (AA) is a chronic airway inflammatory disease characterized by airway hyper-responsiveness (AHR). Pudilan anti-inflammatory oral liquid (PDL) along with its main medicinal material, Taraxaci Herba ( Taraxacum mongolicum Hand.-Mazz , TH) has been widely used to treat upper respiratory tract infections. Research has shown that the major ingredient of TH, the organic acid component (OAC), possesses favorable AA activity. However, the attenuated effects of PDL and OAC from TH (TH-OAC) on AA and their possible mechanisms remain poorly understood. This study analyzed the attenuating effects of PDL and TH-OAC on AA and the underlying mechanisms. Methods: Young BALB/c mice were sensitized and stimulated to develop asthma using ovalbumin. Histological examinations were performed by hematoxylin and eosin staining. Western blotting, immunohistochemistry, and protein expression detection of toll-like receptor 2 (TLR2), TLR4, and orosomucoid 1-like protein 3 (ORMDL3) were performed to detect the presence of inflammatory components in the lung tissue. The messenger RNA (mRNA) expression levels were determined using quantitative real-time polymerase chain reaction. Results: Results showed that PDL and TH-OAC alleviated augmented AHR and typical asthmatic pathological changes, including inflammatory infiltration and thickening of the alveolar wall. They also significantly reduced the levels of the immunoglobulin E, IL-4, IL-5, IL-6, tumor necrosis factor-α, and Nitric oxide (NO) in lung tissues of mice. Protein and mRNA expression levels of TLR2, TLR4, and ORMDL3 were downregulated following treatment with PDL and TH-OAC. Conclusions: PDL and TH-OAC can reduce asthma-induced inflammatory damage to the bronchi. These results provide a theoretical basis for the treatment of asthma in clinical settings.

Comprehensive Summary Supramolecular-polymeric hybrid hydrogels combining advantages of the assembled supramolecular networks and polymeric networks have attracted considerable attention recently. However, they are rarely used as multi-functional wound dressing materials. In this work, we report a supramolecular-polymeric hybrid hydrogel consisting of a co-assembled DBS-COOH/Naproxen network (DBS/NAP) and a polymeric gelatin (G)/quaternary ammonium group (Q) and phenylboronic acid groups (PBA)-grafted chitosan (QCS-PBA) network (G/QCS) for accelerating skin wound healing. The polymeric networks could obviously enhance the mechanical properties of the drug-derived supramolecular networks. Q groups endowed the hydrogel with enhanced antibacterial properties. Borate ester crosslinking between PBA groups and diol groups in DBS-COOH could effectively scavenge reactive radicals. The hybrid hydrogel exhibited tunable mechanical and adhesive properties due to the temperature-responsive gelatin networks. NAP could gradually release from hybrid hydrogel networks thus continuously relieving inflammation. Finally, the biocompatible, adhesive, antibacterial and antioxidant hybrid G/QCS-DBS/NAP gel could promote the in vivo healing stages in a full-thickness wounds with increased collagen deposition, upregulated CD31 expression and down-regulated TNF-α expression. Overall, this multi-functional supramolecular-polymeric hybrid hydrogel exhibited great potential for treating skin defects as promising wound dressing materials.

A rapid, sensitive, and reliable ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method has been developed to simultaneously determine the major bioactive components of Xiaoyan Lidan Formula (XYLDF) in rat plasma, using sulfamethoxazole as the internal standard (IS). The seven major bioactive components are andrographolide, dehydroandrographolide, enmein, 1-methoxicabony-β-carboline, 4,5-dimethoxy-canthin-6-one, 4-methoxy-5-hydroxy-canthin-6-one, and 1-hydroxymethyl-β-carboline. After pretreating by protein precipitation with methanol, separation was performed on a UPLC C18 column using gradient elution with a mobile phase consisting of acetonitrile and 0.1% formic acid at a flowing rate of 0.7 mL/min. Detection was performed on TSQ Quantum mass spectrometry set at the positive/negative ionization and multiple reaction monitoring (MRM) mode. The intra- and inter-day precision were less than 9.8%, whereas the intra- and inter-day accuracy were within ± 13.4%. The method was validated and applied to compare the pharmacokinetic profiles of the analytes in serum of Alpha-naphthylisothiocyanate (ANIT)-induced cholestasis and control rats after oral administration of XYLDF. The results showed remarkable differences in pharmacokinetic properties of the analytes between cholestatic (model) and control groups, thereby providing essential scientific information for better understanding of mechanism of XYLDF and a reference for its clinical applications.
