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.

ObjectiveTo evaluate pharmacological effects of Shengmai injection(SMI)on cerebral ischemia and study its neuroprotective mechanism. MethodsMale specific pathogen-free (SPF) Sprague-Dawley (SD) rats were randomly divided into a sham group, a model group, a low-dose SMI group(3 mL·kg-1), a middle-dose SMI group(6 mL·kg-1), a high-dose SMI group(12 mL·kg-1), and a Ginaton group(4 mL·kg-1)according to the random number table method, with 12 rats in each group. The rat model of cerebral ischemia-reperfusion(MCAO/R)was prepared via the suture method. The administration groups were intraperitoneally injected with corresponding concentrations of SMI or Ginaton injection after reperfusion, which was conducted for 3 consecutive days. The sham group and model group were administered the equivalent volume of physiological saline. The pharmacological effects of SMI on brain injury in MCAO/R rats were evaluated by neurological function scores, cerebral infarction area, hematoxylin-eosin (HE) staining, Nissl staining, terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) staining, and Western blot. The dominant link and key protein of SMI treating cerebral injury were explored using proteomic analysis. The related mechanisms of SMI were further validated using enzyme-linked immunosorbent assay (ELISA), Western blot, and chloride ion fluorescence probe with oxygen-glucose deprivation/reoxygenation(OGD/R)-treated PC12 cells and MCAO/R rats. ResultsCompared with the sham group, the model group showed significantly increased neurological function scores, cerebral infarction area, neuronal apoptosis rate, and expression levels of apoptosis related proteins (P<0.05, P<0.01)and significantly decreased density of Nissl bodies and neurons(P<0.01). Compared with the model group, the SMI groups exhibited significantly decreased neurological function scores, cerebral infarction area, neuronal apoptosis rate, and expression levels of apoptosis related proteins (P<0.05, P<0.01)and significantly increased density of Nissl bodies and neurons (P<0.05). The proteomic analysis results showed that oxidative stress and inflammatory response were important processes of SMI intervening in MCAO/R injury, and the chloride intracellular channel protein 1 (CLIC1) was one of key proteins in its action network. The levels of representative indicators of oxidative stress and inflammatory response in the MCAO/R rats of the SMI groups were significantly reduced, compared with those in the model group(P<0.05, P<0.01), and the expression levels of CLIC1 and downstream NOD-like receptor protein 3 (NLRP3) decreased (P<0.01). In addition, the experimental results based on the OGD/R PC12 cells showed that SMI significantly increased the cell survival rate(P<0.01) and significantly decreased the intracellular chloride ion concentration(P<0.05). ConclusionSMI has neuroprotective effects. Oxidative stress and inflammatory response are key processes of SMI intervening in MCAO/R injury. The potential mechanism is closely related to the regulation of CLIC1.

Allergic rhinitis (AR) is one of the most common chronic non-infectious inflammatory diseases in children. Traditional Chinese medicine (TCM) employs a comprehensive therapeutic system integrating treatment by stages and syndrome differentiation and treatment, demonstrating significant advantages in the management of pediatric AR. This article systematically reviews the clinical treatment methods and underlying mechanisms of TCM for pediatric AR in recent years. It is found that internal therapies (such as herbal formulas or Chinese patent medicines like Xiaoqinglong decoction, Yiqi tuomin decoction), external therapies (including intradermal needles, acupoint application, tuina, and herbal nasal therapy), as well as combined internal and external approaches (oral herbs combined with acupoint application), have demonstrated significant effects in alleviating clinical symptoms, improving immune indicators, and reducing recurrence rates in children with AR. The underlying mechanisms are primarily associated with the regulation of signaling pathways such as Toll-like receptor/nuclear factor-kappa B and mitogen-activated protein kinase, thereby modulating immune balance, suppressing inflammatory responses, inhibiting pyroptosis, reducing mucus secretion, and promoting nasal mucosal repair.

Objective:To explore the impact of uncertain resection on postoperative survival in non-small cell lung cancer.Methods:This is a retrospective cohort study. A retrospective analysis was conducted on the data of 477 patients with non-small cell lung cancer who underwent lobectomy in the Department of Thoracic Surgery, the Fourth Hospital of Hebei Medical University from December 2012 to December 2013. There were 302 males and 175 females, aged (59±8) years (range: 27 to 79 years). According to the surgical resection criteria issued by the International Association for the Study of Lung Cancer, the patients were divided into the intact resection group (R0 group, 286 cases) and the uncertain resection group (R (un) group, 191 cases). Clinical data between the two groups were compared using χ2 test, and propensity score matching (PSM) was performed on patients using the R language, with matching variables including gender, age, smoking history, adjuvant therapy, TNM stage, pathological type, and tumor site. The nearest-neighbor method was used for 1∶3 matching and the caliper value was 0.02. The survival curve was plotted using the Kaplan-Meier method and compared using the Log-rank test. The Cox proportional hazards regression model was used to identify risk factors in overall survival (OS). Subgroup analysis was based on TNM staging and mediastinal lymph node metastasis status. Results:In the R (un) group, 68 patients had positive lymph in the highest group and 129 patients did not undergo complete dissection of the mediastinal lymph nodes. The baseline data for the R0 group and the R (un) group were corrected using PSM, and a total of 369 patients were successfully matched, including 227 cases in the R0 group and 142 cases in the R (un) group. After PSM, the 5-year survival rates of the R0 group and the R (un) group were 64.3% and 52.1%, respectively ( P=0.021). The 5-year survival rates of stage Ⅰ, Ⅱ, and Ⅲ patients were 85.2%, 65.9%, and 34.8%, respectively ( P<0.01). TNM stage ( χ2=46.913, P<0.01), pathological classification of adenosquamous cell carcinoma ( HR=5.970, 95% CI: 3.117 to 11.431, P<0.01) and R (un) resection ( HR=1.512, 95% CI: 1.065 to 2.147, P=0.021) were prognostic factors for postoperative survival. Subgroup analysis showed that in stage Ⅲ patients, 5-year survival rates of the R0 group and the R (un) group after resection were 45.8% and 9.5%, respectively ( P=0.002). Among patients with mediastinal lymph node metastasis, 5-year survival rates of the R0 group and the R (un) group were 50.6% and 7.1%, respectively ( P<0.01). Conclusions:TNM staging, pathological type, and R (un) resection are prognostic factors for overall postoperative survival in non-small cell lung cancer. In stage Ⅰ and Ⅱ patients, R (un) is not a prognostic factor for postoperative survival of non-small cell lung cancer. In patients with stage Ⅲ and mediastinal lymph node metastasis, R (un) is a prognostic factor for non-small cell lung cancer after surgery.

Objective:To investigate the protective effect and possible mechanism of Tangshenbao on renal damage in diabetic nephropathy (DN) rats.Methods:Totally 36 SPF male SD rats were randomly divided into normal group ( n=6) and model group ( n=30). The DN rat model was prepared by single high-dose intraperitoneal injection of STZ. According to the random number table method, the rats were divided into model group, irbesartan group and Tangshenbao low-, medium- and high-dosage groups, with 6 rats in each group. Drug intervention lasted for 8 weeks. The general condition and body weight of rats in each group were recorded. The blood glucose, kidney index, 24 h urine protein (24 h UTP), SCr and BUN levels were detected. The pathological morphology of renal tissue was observed by PAS staining and transmission electron microscopy. The mRNA and protein expressions of Ets-1, TGF-β1, Smad2 and Smad3 in renal tissue were detected by real-time fluorescence quantitative PCR and Western blot. Results:Compared with model group, the body weight of Tangshenbao low, medium and high dose groups and irbesartan group significantly increased ( P<0.01). The kidney index decreased ( P<0.05 or P<0.01). The contents of 24 hUTP, BUN and SCr significantly decreased ( P<0.05 or P<0.01). Glomerular volume was significantly reduced ( P<0.05 or P<0.01), the mRNA expressions of Ets-1 (1.59 ± 0.06, 1.47 ± 0.04, 1.31 ± 0.03, 1.39 ± 0.03 vs. 1.64 ± 0.04), TGF-β1 (1.65 ± 0.05, 1.59 ± 0.03, 1.38 ± 0.05, 1.49 ± 0.04 vs. 1.77 ± 0.08), Smad2 (1.48 ± 0.05,1.39 ± 0.05, 1.22 ± 0.03, 1.31 ± 0.04 vs. 1.54 ± 0.05), Smad3 (1.57 ± 0.04, 1.48 ± 0.03, 1.28 ± 0.03, 1.39 ± 0.02 vs. 1.64 ± 0.05) in renal tissue of rats significantly decreased ( P<0.05 or P<0.01), the protein expressions of Ets-1 (1.33 ± 0.32, 1.16 ± 0.38, 0.77 ± 0.06, 0.84 ± 0.06 vs. 1.97 ± 0.43), TGF-β1 ( 1.35 ± 0.14, 1.24 ± 0.22, 0.94 ± 0.13, 1.07 ± 0.06 vs. 1.63 ± 0.20), Smad2 (1.24 ± 0.26, 1.14 ± 0.31, 0.77 ± 0.28, 0.85 ± 0.19 vs. 1.72 ± 0.34) and Smad3 (1.29 ± 0.14, 1.19 ± 0.21, 0.85 ± 0.39, 0.90 ± 0.37 vs. 1.76 ± 0.21) decreased ( P<0.05 or P<0.01). Conclusion:Tangshenbao can improve renal damage in DN rats, and its mechanism may be related to the inhibition of Ets-1 expression and TGF-β1/Smads signaling pathway.
