ObjectiveTo investigate the effects and underlying mechanisms of Shenqi Wenfei prescription (SQWF) on chronic obstructive pulmonary disease (COPD). MethodsA rat model of COPD with lung Qi deficiency was established using lipopolysaccharide (LPS) combined with cigarette smoke. Forty-eight SD rats were randomly divided into a blank group, a model group, low-, medium-, and high-dose SQWF groups (2.835, 5.67, 11.34 g·kg-1), and a Yupingfeng group (1.35 g·kg-1). Drug administration began on day 29 after modeling and continued for 2 weeks. The general condition of the rats was observed, and the lung function in each group was assessed. Hematoxylin-eosin (HE) staining was used to observe pathological changes in lung tissue. The proportion of inflammatory cells in bronchoalveolar lavage fluid (BALF) was measured. Apoptosis in lung tissue was examined by terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) staining. The release level of lactate dehydrogenase (LDH) in BALF was detected by a microplate assay. Reactive oxygen species (ROS) levels in lung tissue were detected using fluorescent probes. The levels of malondialdehyde (MDA), total superoxide dismutase (SOD), and reduced glutathione (GSH) in BALF were measured by biochemical methods. Ultrastructural changes in lung cells were observed via transmission electron microscopy. Double immunofluorescence staining was performed to detect the expression of thioredoxin-interacting protein (TXNIP) and nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) in lung tissue. Western blot analysis was used to detect the protein expression of TXNIP, NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), cysteinyl aspartate-specific protease-1 (Caspase-1), Caspase-1 p20, gasdermin D (GSDMD), GSDMD N-terminal active fragment (GSDMD-N), interleukin-1β (IL-1β), and IL-18 in lung tissue. Serum IL-1β and IL-18 levels were measured by ELISA. ResultsCompared with the blank group, the model group showed lassitude, fatigue, tachypnea, and audible phlegm sounds, and lung function significantly declined (P0.01). Pulmonary emphysema and inflammatory cell infiltration were obvious. The level of inflammatory cells in BALF increased significantly (P0.05). The number of TUNEL-positive cells increased (P0.01). Levels of LDH, ROS, and MDA in BALF increased significantly (P0.01), while GSH and SOD activities decreased significantly (P0.01). Lung tissue cells showed irregular morphology, swollen mitochondria, disrupted cell membranes, and abundant vesicles, i.e., pyroptotic bodies. Protein levels of TXNIP, NLRP3, ASC, Caspase-1, Caspase-1 p20, GSDMD, GSDMD-N, IL-1β, and IL-18 in lung tissue were significantly elevated (P0.01), and serum IL-1β and IL-18 levels also increased significantly (P0.01). Compared with the model group, each medication group showed alleviation of qi deficiency symptoms and improved lung function (P0.01). Pulmonary emphysema and inflammatory cell infiltration were reduced. Inflammatory cell levels decreased (P0.05). The number of TUNEL-positive cells decreased significantly (P0.01). Levels of LDH, ROS, and MDA decreased significantly (P0.05), while GSH and SOD activities significantly increased (P0.01). Morphological and structural damage in lung tissue was improved to varying degrees. Protein levels of TXNIP, NLRP3, ASC, Caspase-1, Caspase-1 p20, GSDMD, GSDMD-N, IL-1β, and IL-18 in lung tissue significantly decreased (P0.01), and serum IL-1β and IL-18 levels also decreased significantly (P0.05). ConclusionSQWF can improve lung function and alleviate inflammatory responses in COPD rats. Its mechanism may be related to regulating the ROS/TXNIP/NLRP3 pathway and inhibiting pyroptosis.

Objective To analyze the differences of free and esterified oxo-eicosatetraenoic acids (oxo-ETEs) in blood cells and plasma from arterial and venous blood in hemodialysis (HD) patients. Methods Arterial and venous blood samples from 12 patients with end-stage renal disease (ESRD) before and after HD treatment at Charité – Universitätsmedizin Berlin, Germany, from June to December 2020 were collected. The esterified and free oxo-ETEs derived from arachidonic acid in blood cells and plasma were measured by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Results Neither esterified nor free oxo-ETEs in blood cells displayed significant arteriovenous differences before and after HD. HD predominantly affected the metabolic levels of esterified and free oxo-ETEs in plasma. HD reduced the arteriovenous differences of esterified 12-oxo-ETE, free 15-oxo-ETE, and free 5-oxo-ETE in plasma, while raised the arteriovenous differences of esterified 15-oxo-ETE. Conclusions The oxo-ETEs in blood cells are relatively well-stabilized responding to HD treatment, whereas arteriovenous differences of free and esterified oxo-ETEs in plasma are present and active in response to HD treatment, potentially contributing to the cardiovascular disease.

ObjectiveBased on ultra performance liquid chromatography-quadrupole-electrostatic field orbital trap high-resolution mass spectrometry(UPLC-Q-Orbitrap-MS), to identify the in vivo and in vitro chemical components of total phenolic acids in Gei Herba(TPAGH), and to clarify the pharmacological effects and potential mechanisms of the effective part in promoting acute wound healing and inhibiting scar formation. MethodsUPLC-Q-Orbitrap-MS was used to identify the chemical components of TPAGH and ingredients absorbed in vivo after topical administration. A total of 120 ICR mice were randomly divided into the model group, recombinant human epidermal growth factor(rhEGF) group(4 mg·kg-1), and low, medium, and high dose groups of TPAGH(3.5, 7, 14 mg·kg-1), with 24 mice in each group. A full-thickness skin excision model was constructed, and each administration group was coated with the drug at the wound site, and the model group was treated with an equal volume of normal saline, the treatment was continued for 30 days, during which 8 mice from each group were sacrificed on days 6, 12, and 30. The healing of the wounds in the mice was observed, and histopathological changes in the skin tissues were dynamically observed by hematoxylin-eosin(HE), Masson, and Sirius red staining, and enzyme-linked immunosorbent assay(ELISA) was used to dynamically measure the contents of interleukin-6(IL-6), tumor necrosis factor-α(TNF-α), vascular endothelial growth factor A(VEGFA), matrix metalloproteinase(MMP)-3 and MMP-9 in skin tissues. Network pharmacology was used to predict the targets related to the promotion of acute wound healing and the inhibition of scar formation by TPAGH, and molecular docking of key components and targets was performed. Gene Ontology(GO) biological process analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were carried out for the related targets, so as to construct a network diagram of herbal material-compound-target-pathway-pharmacological effect-disease for further exploring its potential mechanisms. ResultsA total of 146 compounds were identified in TPAGH, including 28 phenylpropanoids, 31 tannins, 23 triterpenes, 49 flavonoids, and 15 others, and 16 prototype components were found in the serum of mice. Pharmacodynamic results showed that, compared with the model group, the TPAGH groups showed a significant increase in relative wound healing rate and relative scar inhibition rate(P<0.05), and the number of new capillaries, number of fibroblasts, number of new skin appendages, epidermal regeneration rate, collagen deposition ratio, and Ⅲ/Ⅰ collagen ratio in the tissue were significantly improved(P<0.05, 0.01), the levels of IL-6, TNF-α, MMP-3 and MMP-9 in the skin tissues were reduced to different degrees, while the level of VEGFA was increased. Network pharmacology analysis screened 10 core targets, including tumor protein 53(TP53), sarcoma receptor coactivator(SRC), protein kinase B(Akt)1, signal transducer and activator of transcription 3(STAT3), epidermal growth factor receptor(EGFR) and so on, participating in 75 signaling pathways such as advanced glycation end-products(AGE)-receptor for AGE(AGE/RAGE) signaling pathway, phosphatidylinositol 3-kinase(PI3K)/Akt signaling pathway, mitogen-activated protein kinase(MAPK) signaling pathway. Molecular docking confirmed that the key components genistein, geraniin, and casuariin had good binding ability to TP53, SRC, Akt1, STAT3 and EGFR. ConclusionThis study comprehensively reflects the chemical composition of TPAGH and the absorbed components after topical administration through UPLC-Q-Orbitrap-MS. TPAGH significantly regulates key indicators of skin healing and tissue reconstruction, thereby clarifying its role in promoting acute wound healing and inhibiting scar formation. By combining in vitro and in vivo component identification with network pharmacology, the study explores how key components may bind to targets such as TP53, Akt1 and EGFR, exerting therapeutic effects through related pathways such as immune inflammation and vascular regeneration.

Colorectal cancer (CRC) ranks as the second leading cause of cancer death worldwide. Although preventive colonoscopy screening has improved the survival rate of CRC patients in the past few years, there are still many patients diagnosed after symptoms appear. The surgery for CRC carries high risks and high recurrence, and ideal therapies remain to be developed. The Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway has become a focus of research due to its central role in cellular activities. As a classic oncogenic pathway, the JAK/STAT signaling pathway offers new possibilities for diagnosing and treating various malignancies, and it paves a new way for developing therapies for CRC. This pathway not only participates in basic cellular processes, such as proliferation, differentiation, and apoptosis but also plays a crucial role in immune responses and inflammation. Abnormal activation of the JAK/STAT signaling pathway is closely related to the occurrence and development of CRC. Studies have shown that the active components and compound prescriptions of traditional Chinese medicine (TCM) can inhibit the proliferation, invasion, migration, and angiogenesis while promoting the apoptosis and autophagy of CRC cells by interfering with the JAK/STAT signaling pathway. Furthermore, this pathway may also play a role in regulating the sensitivity of tumor cells to chemotherapy and radiotherapy, thus influencing the effectiveness of tumor treatment and impeding the progression of CRC. In recent years, research results have been updated rapidly, and previous literature summaries have failed to incorporate the latest findings, creating obstacles to accessing current literature. Therefore, this article supplements and summarizes information from the definition of the JAK/STAT pathway, association of this pathway with CRC, and TCM intervention of CRC. This review aims to provide references for future development of molecular biology regarding CRC and the research and development of new drugs.

Surgical treatment is one of the key approaches for non-small cell lung cancer (NSCLC). Regular postoperative follow-up is crucial for early detection and timely management of tumor recurrence, metastasis, or second primary tumors. A scientifically sound and reasonable follow-up strategy not only extends patient survival but also significantly improves quality of life, thereby enhancing overall prognosis. This consensus aims to build upon the previous version by incorporating the latest clinical research advancements and refining postoperative follow-up protocols for early-stage NSCLC patients based on different treatment modalities. It provides a scientific and practical reference for clinicians involved in the postoperative follow-up management of NSCLC. By optimizing follow-up strategies, this consensus seeks to promote the standardization and normalization of lung cancer diagnosis and treatment in China, helping more patients receive high-quality care and long-term management. Additionally, the release of this consensus is expected to provide insights for related research and clinical practice both domestically and internationally, driving continuous development and innovation in the field of postoperative management for NSCLC.

ObjectiveBased on analytic hierarchy process(AHP)-criteria importance through intercriteria correlation(CRITIC) hybrid weighting method, grey relational analysis and backpropagation artificial neural network(BP-ANN), to optimize the water extraction process of Qizhi prescription, so as to provide an experimental basis for optimization of the preparation process of this prescription and the establishment of quality standards. MethodsL9(34) orthogonal test was employed, and the AHP-CRITIC hybrid weighting method was utilized to determine the weight coefficients of the quality fractions of various components, including astragaloside Ⅳ, polygalaxanthone Ⅲ, calycosin-7-O-β-D-glucoside, tenuifolin, and 3,6′-disinapoylsucrose, as well as the dry extract yield. The comprehensive score of each factor level combination in the orthogonal test were calculated as evaluation indicator to select the optimal extraction process parameters. The effects of extraction times, extraction time, and solvent dosage on the aqueous extraction process of the formula were investigated through intuitive analysis, variance analysis, and grey relational analysis. Meanwhile, a BP-ANN model was established to reverse-predict the optimal extraction process parameters of Qizhi prescription, and the optimized process parameters were validated. ResultsThe weight coefficients of the five index components(astragaloside Ⅳ, tenuifolin, calycosin-7-O-β-D-glucoside, polygalaxanthone Ⅲ, and 3,6′-disinapoylsucrose) and dry extract yield were 25.7%, 20.82%, 16.41%, 12.45%, 15.96% and 8.67%, respectively. The optimized extraction process parameters were extracted 3 times with 8, 6, 6 times the amount of water, each time for 1 h. The network prediction results of BP-ANN test samples were consistent with the orthogonal test results, and the mean square error(MSE) of the predicted and measured values of the network was <1%. The water extraction process of Qizhi prescription analyzed and predicted by relevant mathematical models was stable and feasible, which could effectively improve the extraction efficiency of the active ingredients of Astragali Radix and Polygalae Radix, and the average comprehensive score of the validation test was 90.85 with the relative standard deviation(RSD) of 1.55%. ConclusionThis study establishes a water extraction process for compound Qizhi granules, and the optimized extraction process can effectively improve the extraction efficiency of active ingredients, which provides useful references for the optimization of preparation process and the establishment of quality standards for other clinical experience formulas.
