Cancer is a severe threat to human life and health.The over-activation of oncogenes is the main reason for poor treatment and prognosis of cancer patients.Most of these over-activated oncogenes are protein tyrosine kinase(PTK).Among many PTKs,non-receptor tyrosine kinase(NRTK)is an important signaling molecule that regulates cell proliferation and migration as the primary driver of intracellular signaling pathway transduction.Targeting NRTK has become the focus and difficulty in developing anti-tumor drugs.Traditional Chinese medicine(TCM),with its characteristics of multi-channel,multi-link,multi-target,and low toxicity,plays a significant advantage in treating adjuvant tumors.So far,it has been found various traditional TCM monomers can inhibit NRTK from playing an anti-tumor role.This review summarized the part of Src,Jak,Abl,Fak families,the prominent members of NRTK in tumor progression,as well as the TCM monomers acting on these members.We aimed to provide a theoretical basis for the anti-tumor therapy targeting NRTK and a reference for the search for TCM monomer inhibitors of NRTK.

Tumor-associated macrophages (TAMs), a crucial component of the tumor microenvironment (TME), are closely associated to the growth, invasion, metastasis, and prognosis of breast cancer. Targeting TAMs is considered to be a potential new strategy for improving the therapeutic efficacy of breast cancer. TAMs interact with breast cancer cells and influence the development and progression of various breast cancer subtypes through multiple pathways, including the secretion of proteins, cytokines, chemokines, and exosomes. Anti-breast cancer drugs targeting TAMs and emerging therapies are continually being discovered. This article explores the effects and mechanisms of TAMs in different breast cancer subtypes, examines the anti-breast cancer effects of herbal extracts and their active ingredients targeting TAMs, and introduces new technologies such as nano-agents, gene therapy, and immunocellular therapy that target TAMs. These therapeutic strategies targeting TAMs may be critical in improving the therapeutic efficacy and prognosis of breast cancer patients.

In order to explore a suitable pathway for the scientific and technological achievement transformation at prefecture-level public hospitals, in October 2020, a prefecture-level tertiary hospital carried out the " 3+ 3+ 3" mode for scientific and technological innovation and achievement transformation. A three-level management structure was established, consisting of the ministry of science and education, the working group on the transformation of scientific and technological achievements, and the leading group. Three management systems were improved and formulated, including the " measures for reimbursement and rewards of scientific and technological achievements ", the " measures for intellectual property management", and the " implementation plan for promoting the transfer and transformation of scientific and technological achievements". The management measures for the three stages of intellectual property protection, incubation of scientific and technological achievements, and transfer and transformation of achievements were improved. These measures provided organizational support, institutional support, and feasible paths for this practice. After nearly three years of practice, hospitals had reduced the number of low-quality patent applications, and the number and amount of scientific and technological achievements transformed increased from 1 achievement and 10 000 yuan in 2020 to 9 achievements and 320 000 yuan in 2022. This exploration could provide a reference for the transfer and transformation of professional scientific and technological achievements in prefecture-level public hospitals in China.

Objective To analyze the main active components and potential molecular mechanism of Sophora flavescens against breast cancer based on network pharmacology and molecular docking. Methods The chemical constituents were collected and screened by TCMSP, ETCM database and literature review. The targets of active ingredients were predicted by Swiss Target Prediction database. Breast cancer-related targets were collected by GeneCards, TTD, Drugbank and OMIM. The anti-breast cancer targets of Sophora flavescens were screened by Venny 2.1.0 software. Cytoscape software was used to construct the network diagram of Sophora flavescens-key active ingredients-targets. STRING database was used to analyze the common targets, and PPI network diagram was constructed. GO function enrichment analysis and KEGG pathway enrichment analysis of key target proteins were performed by DAVID database and Hiplot online platform. Schrodinger software was used to calculate the molecular docking between the active ingredients and targets. Molecular biological methods were used to verify the key targets. Results A total of 36 active components with clear structures were screened from Sophora flavescens. 70 anti-breast cancer targets of Sophora flavescens were screened out. 12 core targets including EGFR, AKT1, ESR1, SRC, CYP19A1, AR and ABCB1 participate in endocrine resistance, EGFR tyrosine kinase inhibitors and estrogen signaling pathways in breast cancer. Moreover, the docking score between the core component and the key target AR is the highest. In vitro experiments showed that the extract of Sophora flavescens can inhibit the proliferation of breast cancer cells, induce cell apoptosis and up-regulate AR protein expression. Conclusion It was revealed that Sophora flavescens plays an anti-breast cancer role by regulating complex biological processes through multiple components acting on multiple targets and signaling pathways. The upregulation of AR protein by Sophora flavescens may become a new therapeutic strategy for the treatment of breast cancer.

Paclitaxel is the first-line chemotherapy drug for a variety of cancers. However, the paclitaxel resistance greatly reduced the efficacy in the later treatment stage, which seriously increased the mortality and recurrence rate of cancer and limited the clinical application of paclitaxel. At present, Chinese medicine compound prescription, proprietary Chinese medicine, and Chinese medicine injection are widely used as the adjuvant chemotherapy drugs for the treatment of cancer in clinic. Chinese medicine has shown unique advantages in improving the efficacy of chemotherapy drugs and the prognosis of chemotherapy, and reducing the toxic and side effects. However, the specific mechanism and effective monomer composition of Chinese medicine for reversing the resistance of chemotherapy drugs are unclear, and the application of Chinese medicine in different types of cancer is also limited, which are worthy of further exploration. This review summarized the composition of Chinese medicine monomer with synergistic antitumor effect combined with paclitaxel in recent years. The specific mechanism and pharmacological activities of Chinese medicine monomer reversing paclitaxel resistance were classified. This review found that through acting on the membrane transport protein, Chinese medicine monomer promoted the accumulation of paclitaxel in tumor cells, inhibited the expressions of protein and metabolic enzyme related to multidrug resistance and the metabolism of paclitaxel, and regulated the levels of apoptosis genes and factors and apoptosis-related pathways to promote the inhibitory effect of paclitaxel on cell proliferation. Chinese medicine monomer also significantly improved paclitaxel chemotherapy sensitivity by regulating the expression levels of micro ribonucleic acid (microRNA) and long non-coding ribonucleic acid RNA (lncRNA), inhibiting the characteristics of tumor stem cells and tumor metabolic reprogramming, improving tumor microenvironment, and triggering tumor cell death autophagy and oxidative stress response. This review provides a theoretical basis for clarifying the specific anti-tumor mechanism of Chinese medicine monomer combined with paclitaxel, which is of great significance for the development of new Chinese medicine and the clinical research of the drugs combined with paclitaxel, and has certain value for the application of Chinese medicine combined with other chemotherapy drugs.

Side effects from targeted drugs remain a serious concern.One reason is the nonselective binding of a drug to unintended proteins such as its paralogs,which are highly homologous in sequences and have similar structures and drug-binding pockets.To identify targetable differences between paralogs,we analyzed two types (type-Ⅰ and type-Ⅱ) of functional divergence between two paralogs in the known target protein receptor family G-protein coupled receptors (GPCRs) at the amino acid level.Paralogous protein receptors in glucagon-like subfamily,glucagon receptor (GCGR) and glucagon-like peptide-1 receptor (GLP-1R),exhibit divergence in ligands and are clinically validated drug targets for type 2 diabetes.Our data showed that type-Ⅱ amino acids were significantly enriched in the binding sites of antagonist MK-0893 to GCGR,which had a radical shift in physicochemical properties between GCGR and GLP-1R.We also examined the role of type-Ⅰ amino acids between GCGR and GLP-1R.The divergent features between GCGR and GLP-1R paralogs may be helpful in their discrimination,thus enabling the identification of binding sites to reduce undesirable side effects and increase the target specificity of drugs.
