The global burden of malignant tumors keeps increasing， and the increased morbidity and mortality make malignant tumors one of the major challenges to global health. Currently， malignant tumors are mainly managed by surgical resection， radiotherapy， chemotherapy， targeted therapy， and immunotherapy， which， however， usually cause serious adverse reactions， such as tissue damage， immune function inhibition， and multidrug resistance， affecting the prognosis and quality of life of the patients. Traditional Chinese medicine with low toxic and side effects and multi-target， multi-system， and multi-pathway therapeutic effects has shown positive therapeutic potential in cancer treatment. In particular， the traditional Chinese medicine with the effects of softening hardness and dissipating mass， which contains a variety of active ingredients， have shown strong inhibitory effects on tumor cells. Such medicine can not only directly attack tumor cells and inhibit their proliferation and invasion but also exert therapeutic effects by inducing apoptosis， blocking tumor-related signaling pathways， and inhibiting tumor angiogenesis. In addition， traditional Chinese medicine can improve the overall efficacy of cancer treatment by regulating the immune status of the body and reversing the drug resistance of tumor cells. Traditional Chinese medicine can exert the anti-tumor effect by regulating intracellular signaling pathways， which is one of the research hotspots in this field. Signaling pathways such as signal transducer and activator of transcription 3 （STAT3）， phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR）， and mitogen-activated protein kinase （MAPK） play a key role in the formation and development of tumors. Traditional Chinese medicine can regulate the growth， apoptosis， and metabolic process of tumor cells by affecting the activity of these signaling pathways， thus exerting the therapeutic effects on tumors. Based on these mechanisms， a large number of experimental studies and clinical trials have proved that traditional Chinese medicine has broad prospects in anti-tumor treatment. To further verify these research results and provide a basis for the clinical application of traditional Chinese medicine and the development of new drugs， a systematic review and integrated analysis of the research reports on the anti-tumor effect of traditional Chinese medicine was carried out to summarize the anti-tumor mechanisms of traditional Chinese medicine. This review is expected to promote the wide application of traditional Chinese medicine in anti-tumor treatment worldwide and bring more hope and possibility to cancer patients.

Objective To explore the medication rules of Professor Hua Baojin in the treatment of subsolid pulmonary nodules through retrospective analysis and data mining techniques. Methods The prescriptions of patients with subsolid pulmonary nodules who were diagnosed and treated by Professor Hua Baojin at Guang’anmen Hospital of the Chinese Academy of Chinese Medical Sciences from January 1, 2021 to December 31, 2024 were retrospectively collected. Data were imported into the Ancient and Modern Medical Case Cloud Platform for analysis of drug frequency, four natures and five flavors, meridian tropism, drug association, and hierarchical clustering. Results A total of 455 prescriptions were included, containing 205 kinds of traditional Chinese medicines, with a total frequency of 12048 times. Fifty-seven commonly used drugs were screened out, among which drugs with high frequencies included astragalus membranaceus (raw) and hawthorn fruit (charred). The nature of the drugs was mainly warm, cold, and neutral. The flavor of the drugs was mostly sweet, bitter, and pungent. The meridians they belonged to mainly included the lung, spleen, and liver meridians. Their efficacy was mainly tonifying deficiency, clearing heat, resolving phlegm, and relieving cough and asthma. Association analysis obtained 19 pairs of drug combinations, 21 groups of three-drug combinations, and four groups of four-drug combinations. Hierarchical clustering obtained 10 groups of drug combinations. Conclusion On the basis of the core pathogenesis of subsolid pulmonary nodule, Professor Hua applies the theory of regulating qi and detoxifying; regulating the qi of the liver, spleen, and lung; and detoxifying the toxins of phlegm and blood stasis, providing valuable experience for the clinical treatment of SSN.

Objective To explore the clinical information of female patients with pulmonary nodules and the distribution of traditional Chinese medicine (TCM) syndromes and their elements. Methods A cross-sectional study was conducted to collect the basic information, medical history data, image data, and four diagnostic information of female patients with pulmonary nodules. The distribution characteristics of TCM syndromes and their elements in female patients with pulmonary nodules were determined by KMO test, Bartlett spherical test, systematic cluster analysis, chi-square test, and other methods. Results A total of 721 female patients with pulmonary nodules were included in this study. The patients were mainly 45-59 years old, had secondary school education or above, and had a history of oil smoke exposure as clinical characteristics. The pulmonary nodules were mainly 6-10 mm in size and appeared as multiple and ground glass nodules. The clinical symptoms were mainly fatigue, emotional irritability, and shortness of breath. The main syndromes of disease location were the spleen, liver, and lung; and the main syndromes of disease were phlegm, dampness, and qi deficiency. The main complex syndromes were spleen deficiency and dampness, liver stagnation, and qi/yin deficiency. Conclusion Middle age, high education, and multiple small ground glass nodules are the clinical characteristics of female patients with pulmonary nodules. Exposure to oil smoke is an important cause of the occurrence of female pulmonary nodules. During treatment, attention should be paid to strengthening the spleen, removing dampness, soothing the liver, regulating and tonifying qi, and nourishing yin.

The early response of plant auxin gene family Aux/IAA (auxin/indole-3-acetic acid) and its interaction with auxin response factor (ARF) are important pattern to regulate plant growth and development. This work identified 28 StoIAA and 24 StoARF members based on the whole genome data of the medicinal plant Senna tora L., which were classified into 10 and 8 subfamilies, respectively. Phylogenetic tree and collinearity analysis showed that S. tora has close evolutionary relationship with the IAA and ARF homologous genes of Glycine max, Medicago truncatula, and the segment duplication events dominate the expansion of StoIAA and StoARF. Gene structure analysis showed that the vast majority of StoIAA and StoARF contain characteristic conserved domain. Transcriptome data showed that StoIAAs and StoARFs were expressed in leaves, roots and seeds, some members had tissue specific expression. The StoIAA and StoARF promoter region most contain functional elements related to stress response, growth and development, hormone induction and secondary metabolism. In addition, gene expression analysis showed that many StoIAAs and StoARFs can quickly respond to drought and salt stress and exhibited same expression patterns under both stress condition. The yeast two-hybrid experiment confirmed that StoARF8 and StoARF10 exhibit varying degrees of interaction with multiple StoIAA proteins, respectively. The above results provide a basis for further biological functional analysis of the Aux/IAA and ARF gene family of S. tora.

The gene GeDRP1E encoding dynamin-related protein 1E in Gastrodia elata was cloned by specific primers which were designed based on the transcriptome data of G. elata. Bioinformatics analysis on GeDRP1E gene was carried out by using ExPASy, ClustalW, MEGA, etc. Positive transgenic Arabidopsis plant and potato minituber were obtained with the genetic transformation system of Arabidopsis and potato. The plant height and seed setting rate of transgenic Arabidopsis, and agronomic characters, such as size, weight and starch content of potato minituber of transgenic potato were tested and analyzed. And GeDRP1E gene function was preliminarily investigated. The results showed that the open reading frame of GeDRP1E gene was 1 899 bp in length and 632 amino acids residues were encoded, with a relative molecular weight of 69.90 kDa and a molecular formula of C₃₀₇₉H₄₉₇₃N₈₈₃O₉₃₃S₁₉. It was predicted that the theoretical isoelectric point was 7.27, the instability coefficient was 43.34, and the average hydrophilicity index was -0.259, which was indicative of an unstable hydrophilic protein. GeDRP1E has no transmembrane structure and signal peptide, and was localized in the cytoplasm. The phylogenetic tree showed that GeDRP1E was highly homologous with DRP1E proteins of other plant species, among which GeDRP1E had the highest homology with DcDRP1E (XP_020689662.1) in Dendrobium candidum, reaching 90.05%. GeDRP1E plant expression vector pCambia1300-35Spro-GeDRP1E was constructed by double digests, and Arabidopsis complementary mutant and potato overexpression strain of GeDRP1E gene were obtained by Agrobacterium-mediated gene transformation. Compared with the Arabidopsis AtDRP1E mutant, the height and seed setting rate of the GeDRP1E complementation mutant were rescued. The minituber of GeDRP1E overexpression potato had larger size, heavier weight and higher starch content, comparing to wild-type potato. It was preliminarily induced that GeDRP1E was involved in mitochondrial morphology regulation, which related to the growth and development of Arabidopsis plants and potato miniature. The research results laid a foundation for further elucidating the molecular mechanisms underlying the growth and development of G. elata tuber development.

The theory of "supplementation/drainage for bitter-desire of the five viscera" originated from Elementary Questions （《素问》）， which is an important origin of the theory of supplementation and drainage prescription. By exploring the connotation of the theory of "supplementation/drainage for bitter-desire of the five viscera"， and adopting the archaeological method of literature research， we collected the relevant writings on the theory of "supplementation/drainage for bitter-desire of the five viscera" by the representative physicians of Yishui school， such as ZHANG Yuansu， LI Gao， WANG Haogu， LUO Tianyi， LI Zhongzi， etc.， combed through the inheritance and development of this theory， and explored the contribution of Yishui school on this. It was found that all the physicians of Yishui school， on the basis of inheriting the theory of "supplementation/drainage for bitter-desire of the five viscera"， combined with their own clinical practice to develop this theory， and promoted the application and development of this theory in clinic， such as ZHANG Yuansu's theories of cold-heat deficiency-excess in viscera and bowels， and the theory of viscera and bowels prescription， and LI Gao's theory of ascending and descending， floating and sinking， supplementing and draining in visceral qi， and other academic thoughts rooted in the theory of "supplementation/drainage for bitter-desire of the five viscera" of Elementary Questions. By clarifying the inheritance and development of this theory by physicians of Yishui school， we can deeply understand the connotation and the embedded rules of prescription of this theory， which can not only guide the clinical medication in traditional Chinese medicine， but also provide reference value to the research on the academic thoughts of the Yishui school and the theory of fsupplementation/drainage for bitter-desire of the five viscera.

Objective To explore the therapeutic effect of traditional Chinese medicine(TCM)on subsolid nodule(SSN).Methods A practical randomized controlled study method,including 254 SSN patients was adopted.The patients were divided into the TCM(102 cases)and follow-up(152 cases)groups.The follow-up group received regular check-ups in accordance with the guidelines,and the TCM group received TCM syndrome differentiation treatment for 24 weeks.The two groups were compared in terms of the changes in their SSN diameter,SSN number,TCM symptom score,and overall therapeutic effect before and after treatment.Adverse reactions and safety indicators were also recorded.Results The TCM group showed a significantly higher effective rate of treatment(16.7%)than the follow-up group(2.6%)(P<0.01).Compared with their condition before treatment,the TCM group showed no significant changes in their SSN diameter and number but presented considerably reduced fatigue,yellow and red urine symptoms,and overall TCM symptom score(P<0.05).The follow-up group exhibited significantly increased diameter and number of SSN(P<0.01).The follow-up group showed the significantly higher increase in SSN diameter after treatment than the TCM group(P<0.05).Moreover,the follow-up group showed significantly higher fatigue,depression,yellow and red urine symptom scores,and overall TCM symptom score than the TCM group(P<0.05 or P<0.01).Conclusion TCM treatment for SSN has a distinct clinical efficacy,reduces the malignant risk of SSN and improves clinical symptoms of SSN patients,and is safe and feasible.

Pneumonia caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection poses a threat to human life and health,resulting in great socio-economic losses.The structural protein spike protein(S protein)of viruses has always been considered to primarily mediate virus invasion into host cells.S protein can act independently of viruses and cause inflammatory reactions on a variety of cells,therefore,understanding the impact of S protein on the respiratory tract can provide a new perspective for the prevention and treatment of COVID-19.This article reviews the advances in the possible mechanisms and clinical manifestations of SARS-CoV-2 structural protein S protein-induced inflammatory response in respiratory epithelial cells,aiming to provide reference for the prevention and treatment of diseases.

To investigate the role of chamagogic polysaccharides (polysaccharides of Brassica rapa L., BRPs) against doxorubicin (DOX) cardiotoxicity and related mechanisms, H9c2 cells were selected for the study, and the effects of BRPs on DOX induced damage in H9c2 cells were detected by cell counting kit-8 (CCK-8); H9c2 cells were divided into the control group, the model group, and the drug group (0.5-3 mg·mL^-1); the control group was cultured under normal conditions, and the remaining groups were induced for 24 h by 1 μmol·L^-1 DOX after treatment. Apoptosis was detected by flow cytometry; the levels of lactate dehydrogenase (LDH), superoxide dismutase (SOD) and malondialdehyde (MDA) were measured in each group; intracellular reactive oxygen species (ROS) and mitochondrial membrane potential (MMP) were detected. Western blot was used to detect the expression of proteins related to the apoptosis and transcription factor NF-E2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway. Compared with the control group, DOX-induced H9c2 cell injury was characterized by decreased cell viability, increased apoptosis, elevated LDH and MDA levels, decreased SOD activity, significantly increased ROS levels, and significantly decreased MMP; the level of B cell lymphoma-2 (Bcl-2) protein decreased, and the level of Bcl-2 associated X protein (Bax) increased significantly; In the model group, the expression levels of Nrf-2, HO-1, quinone oxidoreductase 1 (NQO1) were reduced, and the expression levels of Kelch-like ECH-associated protein 1 (Keap1) and phosphorylated p38 mitogen-activated protein kinase were significantly increased, Moreover, BRPs (0.5-3 mg·mL^-1) increased the protein expression levels of Nrf2, HO-1, and NQO1, and decreased the levels of Keap1 and phosphorylated p38 mitogen-activated protein kinase. In summary, the ability of BRPs to protect H9c2 cells and inhibit apoptosis may be related to their regulation of the Nrf2/HO-1 pathway to antagonize oxidative stress.
