The effect of traditional Chinese medicine soaking method on the healing of diabetic foot ulcers: A meta-analysis.

Foot infections, sores or deep tissue damage from diabetes can be a serious psychological and physical injury. This paper aims at making meta-analyses on the therapeutic effects of traditional Chinese medicine (TCM) on diabetic foot ulcers. The Chinese National Knowledge Infrastructure, VIP Database, Wanfang Database and so on, has conducted a randomized controlled trial to evaluate the clinical effect of TCM soaking method for diabetes patients with diabetes. Literature has been determined to be included by computer search and by hand rough checks. The search period was from the creation of the database to October 2023. Review Manager 5.3 was used to analyse the meta data and evaluate it systematically. Altogether, 479 research was conducted in China's data base and 20 of them were eventually collected for the final statistical analysis. In all, 1361 patients were enrolled in the trials. The results indicated that TCM immersion in diabetic foot resulted in significantly improved obvious wound healing (OR, 3.2; 95% CI, 2.5, 4.09, p < 0.0001); results showed that TCM immersion therapy significantly increased the efficiency of effective wound healing (OR, 4.55; 95% CI, 3.25, 6.37, p < 0.001). Statistical significance was found. Using Egger's approach to detect publishing bias suggests that there is no risk of publishing bias in terms of marked wound healing and effective healing. Traditional Chinese drug immersion can increase obviously the recovery ratio and the effective recovery ratio of diabetic foot.

[Mechanism of n-butanol fraction of Wenxia Formula combining with gefitinib in treating non-small cell lung cancer based on network pharmacology and in vitro experiment].

This study combined network pharmacology, molecular docking, and in vitro experiments to explore the potential mechanism of the active components of the n-butanol fraction of Wenxia Formula(NWXF) combined with gefitinib(GEF) in treating non-small cell lung cancer(NSCLC). Ultra-performance liquid chromatography-quadrupole Orbitrap mass spectrometry(UPLC-Q-Orbitrap MS) was employed to detect the main chemical components of NWXF. The active components of NWXF were retrieved from SwissADME, and the candidate targets of these active components were retrieved from SwissTargetPrediction. Online Mendelian Inheritance in Man(OMIM) and GeneCards were searched for the targets of NSCLC. Cytoscape 3.9.0 and STRING were employed to build the protein-protein interaction(PPI) network with the common targets shared by NWXF and NSCLC. Gene Ontology(GO) annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment were performed in DAVID to predict the potential mechanisms. Finally, molecular docking between the main active ingredients and key targets was conducted in SYBYL-X 2.0. The methyl thiazolyl tetrazolium(MTT) assay was employed to evaluate the inhibitory effects of NWXF and/or GEF on the proliferation of human non-small cell lung cancer cells(A549 and PC-9). Additionally, the impact of NWXF on human embryonic lung fibroblast cells(MRC-5) was assessed. The effectiveness of the drug combination was evaluated based on the Q value. The terminal-deoxynucleoitidyl transferase mediated nick-end labeling(TUNEL) assay was employed to examine the apoptosis of A549 and PC-9 cells treated with NWXF and/or GEF. Quantitative real-time PCR(qRT-PCR) was employed to measure the mRNA levels of epidermal growth factor receptor(EGFR), c-Jun N-terminal kinase(JNK), and Bcl2-associated X protein(Bax) in the A549 and PC-9 cells treated with NWXF and/or GEF. Western blot was employed to determine the protein levels of EGFR, p-EGFR, JNK, p-JNK, and Bax in the A549 and PC-9 cells treated with NWXF and/or GEF. A total of 77 active components, 488 potential targets, and 49 key targets involved in the treatment of NSCLC with NWXF were predicted. The results of GO annotation showed that NWXF may treat NSCLC by regulating the biological processes such as cell proliferation, apoptosis, and protein phosphorylation. KEGG enrichment revealed that the key targets of NWXF in treating NSCLC were enriched in the mitogen-activated protein kinase(MAPK), phosphatidylinositol 3-kinase(PI3K)-protein kinase B(AKT), hypoxia-inducible factor-1(HIF-1), and microRNA-related signaling pathways. Molecular docking results showed that 91.9% of the docking scores were greater than 5, indicating the strong binding capability between main active components and key targets. The cell experiments demonstrated that NWXF combined with GEF synergistically inhibited the proliferation, promoted the apoptosis, decreased p-EGFR/EGFR and p-JNK/JNK values, down-regulated the mRNA levels of EGFR and JNK, and up-regulated the mRNA and protein levels of Bax in A549 and PC-9 cells. In conclusion, NWXF combined with GEF can regulate the EGFR/JNK pathway to promote the apoptosis of NSCLC cells, thus treating NSCLC.
