Breast cancer is a kind of malignant tumor with a complex mechanism， and its morbidity and mortality are increasing year by year， which seriously threatens women's health. At present， the main clinical treatments are surgical resection， radiotherapy， chemotherapy， and drug therapy， but they are often accompanied by side effects and adverse reactions， which affect the therapeutic effect. Traditional Chinese medicine （TCM） has the advantages of multi-component and multi-target treatment in the fight against breast cancer. The wnt/β-catenin signaling pathway is one of the classic pathways in cancer research. Abnormally activated Wnt/β-catenin signaling pathway inhibits β-catenin degradation by blocking the formation of Axin/glycogen synthase kinase 3β/adenomatous polyposis coli complex， thus promoting β-catenin nuclear metastasis， and it binds to T cell transcription factor/lymphoenhancer factor-1 to initiate downstream target genes and further interfere with the proliferation， migration， and invasion of tumor cells to affect the tumor process. Previous studies have shown that TCM monomers and compounds can mediate the Wnt/β-catenin signaling pathway to inhibit the malignant phenotype of breast cancer cells， thus playing an anti-breast cancer role， and the biochemical process involved in the regulation of therapeutic drugs has not been systematically combed. By analyzing and collating Chinese and foreign literature at the present stage， this paper discussed the association mechanism between Wnt/β-catenin signaling pathway and breast cancer and analyzed the internal mechanism of TCM monomers and compounds in mediating Wnt/β-catenin signaling pathway to exert anti-breast cancer effect. The statistical results showed that the flavonoids， alkaloids， and terpenoids in TCM monomers could target the Wnt/β-catenin signaling pathway and block the further development of malignant phenotype of breast cancer cells. TCM compounds with functions of clearing heat and detoxifying， promoting blood circulation and removing blood stasis， and tonifying kidney and liver were commonly used to intervene in the Wnt/β-catenin signaling pathway to prevent breast cancer. Compared with the current inhibitors of Wnt/β-catenin signaling pathway， the application of TCM monomers and compounds is expected to bring low-toxicity and high-efficiency breast cancer treatment drugs to the clinical practice， and the existing results provide a reference for the subsequent screening， research， and development of TCM small-molecule compounds and TCM compounds against breast cancer.

OBJECTIVE To investigate the mechanism of the inhibitory effect of total flavonoids from Taraxacum mongolicum on high-fat diet-induced obesity in mice through modulation of intestinal flora. METHODS Twenty-four C57BL/6J mice were randomly divided into blank group， model group and T. mongolicum total flavonoid group， with 8 mice in each group. Except for the blank group， the other 2 groups were given a high-fat diet， while T. mongolicum total flavonoid group was given T. mongolicum total flavonoid [400 mg/（kg·d）] intragastrically， once a day， for 8 consecutive weeks. During the experiment， the food intake of each group of mice was recorded. After the last medication， the body mass， fat weight， blood lipid level and pathological changes of liver and epididymal fat in mice were evaluated to observe the effect of T. mongolicum total flavonoid on the treatment of obesity in mice. The changes in abundance and structure of intestinal flora in mice were detected by amplicon sequencing； the effects of T. mongolicum total flavonoids on fat metabolism related genes were analyzed by qPCR. RESULTS Compared with model group， the body weight of mice in T. mongolicum total flavonoids group was decreased significantly （P＜0.05）； the levels of total lipid cholesterol， triglycerides， and LDL cholesterol were all decreased significantly （P＜0.01）， and the level of HDL cholesterol was increased significantly （P＜0.01）； the fat indexes of inguinal white adipose tissue and epididymal white wind_lz@hactcm.edu.cn adipose tissue were significantly reduced （P＜0.05）； significant improvement in hepatocellular steatosis and adipose cytopathy were significantly improved； mRNA expressions of COX7A1 and COX8B were significantly upregulated （P＜0.05）. The results of bacterial colony detection showed that compared with the model group， there was a rising trend in the diversity of the bacterial colony in T. mongolicum total flavonoids group， and the Sobs index characterization and β diversity were increased significantly （P＜0.05）. Relative abundances of Blautia， norank_f_Ruminococcaceae， Bilophila， Alistipes， classified_f_Ruminococcaceae， Parabacteroides， norank_f_Desulfovibrionaceae， Anaerotruncus were significantly up-regulated（P＜0.05）， while those of Faecalibaculum， Erysipelatoclostridium， GCA-900066575， Tuzzerella， Lactobacillus， norank_f_norank_o_RF39， achnospiraceae_FCS020_group were significantly down-regulated （P＜0.05）. CONCLUSIONS T. mongolicum total flavonoids can reduce body mass， fat weight and blood lipid levels， and repair the pathological damage to liver and epididymal fat in obese mice， which is related to improving intestinal flora disorders caused by high-fat diet.

ObjectiveTo assess the therapeutic effectiveness and safety of the traditional Chinese medicine compound Shenlong decoction in addressing the symptoms of pulmonary deficiency and stasis in patients with idiopathic pulmonary fibrosis （IPF）. MethodsSixty eligible patients with lung deficiency and collateral stasis syndrome of IPF were randomly assigned to the observation （30 patients） and control groups （30 patients）. All patients underwent standard Western medical therapy. Additionally，the observation group received Shenlong decoction granules，while the control group received a placebo. Both treatments were packaged in four doses of 10.5 g each，taken twice daily for three months. The indexes of the patients during the treatment cycle were observed，and the main indexes include traditional Chinese medicine （TCM） syndrome scores and 6 min walk test （6MWT）. The secondary indexes include pulmonary function test ［actual value/expected value of total lung volume （TLC%），actual value/expected value of vital capacity（FVC%），actual/predicted diffusing capacity of the lung for carbon monoxide（DLCO%），actual/predicted forced expiratory volume in one second （FEV₁%），and FEV₁/ forced vital capacity （FVC）］，blood gas analysis ［arterial blood diathesis partial pressure of oxygen （PaO₂），partial pressure of carbon dioxide （PaCO₂），and arterial oxygen saturation （SaO₂）］，serum inflammatory factors ［transforming growth factor-β₁ （TGF-β₁），interleukin-4 （IL-4），interleukin-13 （IL-13），interleukin-12 （IL-12），and gamma-interferon （IFN-γ）］，and quality of survival evaluation ［St George's Respiratory Questionnaire （SGRQ） score］. The patients' clinical manifestations were determined at the end of the treatment， and the occurrence of adverse events was recorded.

In recent years， the incidence and mortality rates of cancer have been increasing， posing a serious threat to human health. Western medicine mainly uses treatments such as surgical resection， chemotherapy， immunotherapy and targeted therapy， but they are prone to complications， drug resistance and adverse reactions. A growing number of studies have shown that traditional Chinese medicine has obvious advantages in the treatment of cancer， reducing the recurrence rate of cancer and improving the quality of survival of patients. Cellular senescence refers to a state of irreversible cell cycle growth arrest when cells cease to proliferate after a limited number of divisions， resulting in a decline in cell proliferation and differentiation capacities and physiological functions， accompanied by morphological changes such as flattening and multinuclear morphology. At the molecular level， it shows increased expression of DNA damage-related genes， reduced expression of cell cycle-related factors and significant secretory activity. The malignant development of cancer is closely related to cellular senescence. With the increasing number of cancer cell proliferation， cancer-related genes undergo continuous mutations， freeing them from cellular senescence and thus achieving unlimited proliferation. Through recent studies， it has been found that induction of tumor cell senescence， possibly through modulation of cellular DNA damage， cell cycle arrest and senescence-associated secretory phenotype （SASP）， which converts the suppressive immune tumor microenvironment to an activated immune tumor microenvironment and thus reverses the escape of tumor cell senescence， is a promising strategy for cancer therapy. However， the mechanism of cellular senescence in cancer progression is not fully understood， especially the anti-cancer role played by traditional Chinese medicine in regulating cellular senescence. This article summarized and concluded the specific molecular mechanisms of cellular senescence， the role of cellular senescence in cancer progression， and the mechanism of anti-cancer effects of traditional Chinese medicine based on cellular senescence from the perspective of regulating cellular senescence， with a view to providing ideas and methods for the anti-cancer effects of traditional Chinese medicine and the development of new drugs.

With the increasing prevalence of total knee arthroplasty (TKA), there is a corresponding rise in the number of patients requiring revision of total knee arthroplasty (R-TKA) for various reasons. R-TKA presents several complex challenges, with severe bone defect reconstruction being a critical obstacle to securing favorable long-term outcomes. Recently, the approach to managing bone defects has seen significant advancements, with a range of techniques proposed contingent on the defect's size and location. Severe bone defects require reconstruction with autologous or allogeneic bone grafts or metal fillers. However, bone grafts have their usage constrained by limited availability, risks of resorption and collapse, and the potential for disease transmission. Consequently, metal fillers have received widespread attention in practical applications due to their advantages, such as comprehensive source, customizability, and safety. The advantages of metal augment are that they provide immediate support without reinforcement and are not subject to necrosis and resorptive collapse. However, the difference in elastic modulus between metal and bone may lead to stress shielding and increase the risk of potential bone loss. Both Cone and Sleeve can achieve biological fixation of metaphyseal bone; however, in cases of periprosthetic infections, it is generally difficult to remove them easily due to the prosthetic bone in-growth and osseointegration. This study aims to provide a comprehensive review of the use of metal fillers to reconstruct bone defects during R-TKA. It is intended to aid orthopedic surgeons in understanding the spectrum of reconstructive possibilities and provide high-performance revision strategies for their patients.

Vitiligo is an acquired depigmented disease, and neurological factors may play an important role in its pathogenesis. Neurogenic inflammatory factors released by sensory nerves that control the skin can directly or indirectly regulate functions of keratinocytes, melanocytes, Langerhans cells, dermal dendritic cells, mast cells, dermal microvascular endothelial cells and immune cells. This review summarizes roles of several relevant neurogenic inflammatory factors in the occurrence and development of vitiligo, including neuropeptide Y, calcitonin gene-related peptide, catecholamines and nerve growth factor, with a view to providing new ideas for clinical treatment of vitiligo.
