Cancer has become a significant global public health issue， severely impacting public health and societal development. Despite advances in tumor treatment methods in recent years and a gradual decline in cancer mortality rates， drug-related adverse reactions and drug resistance remain substantial challenges. Traditional Chinese medicine （TCM） has demonstrated significant clinical efficacy in cancer treatment and small side effects， making it widely applied in the field of oncology. Xuefu Zhuyutang， derived from Yilin Gaicuo， is known for its abilities to invigorate blood circulation， dispel blood stasis， promote Qi flow， and alleviate pain. It was specifically formulated by the esteemed WANG Qingren of the Qing dynasty for the "blood stasis syndrome in the blood mansion" and is commonly used to treat Qi stagnation and blood stasis syndrome. Clinical studies have shown that Xuefu Zhuyutang， when combined with conventional Western medications， produces significant effects in the treatment of malignant tumors such as liver cancer， lung cancer， and cervical cancer. It substantially reduces the incidence of adverse reactions following Western treatments， including radiation esophagitis， radiation encephalopathy， radiation-induced oral mucositis， and edema. Additionally， it alleviates cancer-related pain and fever， blood hypercoagulability， and associated complications such as depression and anxiety， and also mitigates chemotherapy-induced side effects like hand-foot syndrome. Basic research has demonstrated its potential anti-tumor mechanisms， including the inhibition of Wnt/β-catenin signaling pathway activation， suppression of mitogen-activated protein kinase （MAPK） pathway activation， and anti-tumor angiogenesis. Pharmacological studies have revealed that its active components inhibit tumor cell proliferation and migration， induce tumor cell apoptosis， suppress tumor angiogenesis， enhance the cytotoxicity of natural killer cells against tumors， improve the tumor microenvironment， and regulate immune function. This paper reviewed the latest research progress on Xuefu Zhuyutang in the treatment of malignant tumors from four aspects： theoretical exploration， clinical studies， mechanisms of action， and pharmacological basis， aiming to provide insights and methods for the clinical diagnosis and treatment of malignant tumors.

Antibody-drug conjugates （ADCs） are a novel class of anti-tumor agents composed of a targeted monoclonal antibody， a cytotoxic drug， and a linker connecting the two. They combine the high specificity of antibodies with the potent cytotoxicity of chemotherapeutic agents. Triple-negative breast cancer （TNBC） is characterized by high aggressiveness， elevated risks of recurrence and metastasis， and poor prognosis， largely due to the lack of effective therapeutic targets. This review summarizes the research progress of ADCs in the treatment of TNBC. It has been found that ADCs targeting human epidermal growth factor receptor 2 （such as trastuzumab deruxtecan）， trophoblast cell surface antigen 2 （such as sacituzumab govitecan and datopotamab deruxtecan）， zinc transporter LIV-1 （such as ladiratuzumab vedotin）， HER-3 （such as patritumab deruxtecan）， epidermal growth factor receptor （such as AVID100）， and glycoprotein non-metastatic melanoma protein B （such as glembatumumab vedotin） have all demonstrated promising therapeutic effects against TNBC. Despite challenges including acquired resistance and treatment-related toxicities， ADCs are undoubtedly reshaping the therapeutic landscape for TNBC and are expected to occupy a more central position in TNBC treatment in the future.

Pulmonary rehabilitation (PR) has become an indispensable component of the modern care continuum for lung cancer. Substantial evidence confirms its definitive value in improving perioperative outcomes, mitigating treatment-related side effects, and enhancing quality of life in patients with advanced disease. However, a significant "implementation gap" exists between its proven clinical benefits and widespread application, primarily characterized by the lack of standardized protocols, uncertainty in optimal timing, and low patient adherence. Bridging this gap requires a dual-driven approach: harnessing technological innovations such as telerehabilitation, wearable devices, and artificial intelligence to enhance accessibility and personalization, alongside optimizing care models through multidisciplinary team collaboration. This review systematically analyzes the evidence, implementation barriers, and innovative pathways for PR in lung cancer care, aiming to catalyze its transition from an ancillary option to a core standard of care, and envisions a new paradigm of personalized PR that is patient-centered, data-driven, and technologically integrated.

Papillary thyroid carcinoma (PTC) can exhibit lateral neck lymph node metastasis at an early stage. Lateral neck lymph node metastasis is a crucial factor affecting the prognosis of PTC and is an absolute indication for neck lymph node dissection surgery. Additionally, it is a relative contraindication of endoscopic surgery for most medical centers. Therefore, the preoperative identification of lateral neck lymph node metastasis is vital for surgical decision-making and prognosis assessment. Ultrasound, CT, cytology, and clinical features can provide some information on lateral neck lymph node metastasis, but their accuracy does not fully meet clinical needs. Deep learning is a primary method for medical image recognition or feature extraction. In recent years, deep learning-based ultrasound, CT, cytology, conventional clinical parameters, or multimodal models combining these data have been developed and are expected to achieve routine clinical application. With the establishment and sharing of large datasets, automated annotation, algorithm optimization, and resolution of data security issues, deep learning is expected to accurately predict lateral neck lymph node metastasis in PTC. Furthermore, it can be integrated into electronic medical record systems for automated real-time analysis and assist clinical decision-making.

Objective To investigate the effect of diosgenin on the proliferation and apoptosis of breast cancer cells and its potential molecular mechanism. Methods The breast cancer cell line MCF-7 was treated with low, medium, and high doses of diosgenin, and cell proliferation was detected through the MMT method. Flow cytometry was used to detect cell apoptosis. Nuclear-cytoplasmic-protein separation method was applied to detect the subcellular localization of death associated protein (DAXX). qRT-PCR and Western blot were used to detect the expressions of DAXX and c-Jun N-terminal kinase pathway (JNK)-related proteins. Results Diosgenin considerably inhibited the proliferation of MCF-7 cells and promoted cell apoptosis in a concentration-dependent manner. Diosgenin can promote the movement of DAXX from nucleus into the cytoplasm. Diosgenin upregulated the expression of cell surface death receptor (Fas), increased the phosphorylation levels of JNK and mitogen activated protein kinase (p38), and activated the JNK/p38 signaling pathway with concentration dependence. Conclusion Diosgenin inhibits the proliferation and promotes the apoptosis of the breast cancer cell line MCF-7, whose mechanism may be related to the regulation of DAXX subcellular localization and the activation of JNK/p38 signaling pathway.

Objective To analyze the correlation of mean corpuscular volume (MCV) with clinical features and the prognosis of patients with treatment-related acute myeloid leukemia (t-AML). Methods The clinical and laboratory data of 41 patients with t-AML were retrospectively analyzed. The patients were divided into LMCV and HMCV groups. Spearman’s rank correlation was used for correlation analysis, and a survival curve was drawn via Kaplan-Meier method. Log-rank test was used for comparison between groups, and Cox proportional risk regression model was used for multivariate analysis. Results The treatment history of G-CSF was positively correlated with the MCV of patients with t-AML (correlation coefficient r=0.325, P<0.05). The amount of RBC and HGB in the peripheral blood of patients and the percentage of PML-RARa positive in the LMCV group were significantly higher than those in the HMCV group, and the percentages of the expression levels of lymphoid antigen CD7 and CD56 were significantly lower than those in the HMCV group (P<0.05). The therapeutic effect, OS, and RFS of the LMCV group were better than those of the HMCV group (P<0.05). Failure to reach CR was an independent risk factor for OS of patients with t-AML (HR=0.053, P=0.002), and MCV≥98.9 fl was an adverse factor for OS and RFS of patients with t-AML (P<0.1) but not an independent risk factor (P>0.05). Conclusion Patients with t-AML with different levels of MCV have different clinical characteristics, and patients with high MCV have poor therapeutic effect and prognosis.
