Angiogenesis, as a core mechanism for maintaining tissue perfusion and repairing ischemic injury, plays a crucial role in ischemic diseases such as coronary heart disease and peripheral arterial disease. Traditional Chinese medicine(TCM), with its advantages of multi-target and synergistic regulation, provides a unique perspective for therapeutic angiogenesis. Based on this, this article intends to delve into the synergistic effects of key signaling pathways, including vascular endothelial growth factor(VEGF)/VEGF receptor(VEGFR), Notch, phosphoinositide 3-kinase/ protein kinase B/mammalian target of rapamycin(PI3K/Akt/mTOR), and angiopoietin/endothelial TEK tyrosine kinase(Ang/Tie2), and elucidate the driving mechanisms of endothelial cell metabolic reprogramming and exosome-mediated intercellular communication within this process. Based on existing literature, it summarizes the microenvironment-dependent and bidirectional regulatory characteristics of natural active components of TCM(such as terpenes, tanshinones, and flavonoids) on angiogenesis. Furthermore, it systematically discusses how classical TCM formulas achieve blood vessel formation and functional maturation by protecting the neurovascular units, recruiting pericytes, and remodeling the microenvironment. Current evidence highlights the advantages of multi-target synergy and temporal regulation in TCM, but also reveals challenges such as high heterogeneity and a lack of functional evaluations and high-quality clinical trials. Future efforts should integrate multi-omics to decipher network mechanisms, optimize formula compatibility, and conduct multicenter studies to promote the development of innovative preparations. This review highlights the academic value of TCM in angiogenesis, provides an evidence base for treating ischemic diseases, and supports multidisciplinary integration and innovation.

Objective This study aimed to investigate the tumorigenic properties of MMTV-PyMT breast cancer transgenic mice at different ages(in weeks)and the changes in the composition of immune cells in the tumor microenvironment.Methods Eight groups of 4,6,8,10,12,14,16 and 18 weeks of age MMTV-PyMT female mice(FVB mice as the background)and one group of 8 weeks of FVB female mice were prepared for routine blood testing,the pathological changes of the mammary gland and lung metastases were observed by histopathological sections,and the immune cells in blood,spleen,and tumor were analyzed by flow cytometry.Results MMTV-PyMT mice showed adenular ductal lesions at 4~6 weeks of age;the ductal portion expanded to the growth boundary at 8~9 weeks of age,and then gradually broke through the glandular boundary to form early breast cancer at 8~12 weeks of age,and advanced breast cancer at 10~14 weeks of age.At 12 weeks of age,metastases were visible in the lungs of some mice,and at 14 weeks of age,the number of metastases in the lungs increased significantly.As the age of the mice increased,the number of white blood cells,neutrophils,and platelets in their blood increased gradually,while the lymphocytes and erythrocytes showed a gradual downward trend.Flow cytometry showed that with the increase in age,the proportion of T cells in the spleen and tumor gradually decreased,the MDSCs in the blood,spleen,and tumor gradually increased,and the NK cells in the tumor also gradually increased.Conclusions This study analyzed routine blood tests,pathology,and immune cells in the tissues of MMTV-PyMT mouse models of different weeks of age,providing a novel perspective on the dynamic alterations of the tumor immune microenvironment during the malignant progression of breast cancer.

Mice are a core model organism in neuroscience and are undergoing a technological transition in whole-brain atlas construction,as researchers shift from traditional anatomical approaches to multidimensional molecular-level analysis.This marks a new phase in brain research method ology,characterized by higher resolution and systemic integration.Spatial transcriptomics technologies have significantly advanced the biological depth of neuroscience studies,offering novel paradigms for exploring dynamic neural circuit evolution and cellular diversity in the brain.By combining traditional anatomical localization,single-cell molecular connectomics,and functional imaging for macroscopic dynamic tracking,brain atlas research achieves"molecule-circuit-behavior"tri-level integration,thereby constructing molecular regulatory networks underlying dynamic neural circuit remodeling.However,current challenges persist in technical integration.Reference brain atlases hold great promise for elucidating brain homeostasis mechanisms,identifying abnormal circuit metabolic features in neurological disorders(e.g.,anxiety),and screening therapeutic targets.Future brain atlas research must advance multimodal technology fusion and cross-dimensional data integration to achieve precise mapping from static structures to dynamic functional networks,and thus provide revolutionary tools for neuroscience.

OBJECTIVE To calculate the cost of centralized dispensing of four categories of drugs (ordinary drugs, antibacterial drugs, hazardous drugs, and parenteral nutrition solutions) in pharmacy intravenous admixture service (PIVAS), and provide reference for setting charging standards for relevant departments. METHODS The operating costs of PIVAS in 12 medical institutions from Shaanxi province were collected through questionnaire survey, including labor costs, medical and health material costs, fixed asset depreciation and repair costs, water and electricity costs, and management costs. The operation time allocation coefficient method and workload allocation coefficient method were comprehensively used to allocate the above costs, and the unit preparation costs of four categories of drugs were calculated. RESULTS The average annual total costs of dispensing ordinary drugs, antibacterial drugs, hazardous drugs, and parenteral nutrition solutions in Shaanxi province were (2 195 900.25±1 680 893.73) yuan, (746 341.59±725 839.39) yuan, (331 420.15±183 258.83) yuan, and (330 322.68±277 281.70) yuan, respectively, with labor costs accounting for the highest proportion, averaging 85.49%. The costs of dispensing a set of ordinary drugs, antibacterial drugs, and hazardous drugs were 5.89, 7.60, and 14.37 yuan, respectively; the cost of dispensing one bag of parenteral nutrition solution was 32.15 yuan (excluding the cost of disposable intravenous nutrition bags). CONCLUSIONS The cost calculation method and data of different types of intravenous drugs obtained in this study can provide reference for relevant departments to formulate and adjust PIVAS fee standards.

Existing studies have shown that Astragalus membranaceus(AM)and its active ingredients astragalus polysaccharides,oninon,and astragalus methyl glycosides can attenuate X-ray radiation-induced injury.However,there are no studies on how isoliquiritigenin(ISL)attenuate the bystander effect of bone marrow mesenchymal stem cells(BMSCs)induced by carbon ion radiation therapy for lung cancer.This study aimed to investigate the AM-derived small molecule ISL to enhance radiotherapy sensitivity by attenuating the carbon ion radiation-induced bystander effect(RIBE)in BMSCs to elucidate its mecha-nism of action.In this study,we established a C57BL/6 mouse lung cancer transplantation tumor model in vivo and a co-culture model of A549 cells and BMSCs in vitro,and the models were successfully treated with carbon ions.In further work,we used flow cytometry,immunofluorescence,Western blot,enzyme-linked immunosorbent assay(ELISA),inhibitor,short hairpin RNA(shRNA),Cell Counting Kit-8(CCK-8),and other methods to illustrate the mechanism.In the next experiments,we found that ISL combined with carbon ion radiotherapy had a significant anti-tumor effect and protected BMSCs from radiation damage.The aim of this study was to investigate the potential of ISL in enhancing the sensitivity of lung cancer cells to radiotherapy and attenuating RIBE in both in vitro and in vivo settings.Traditional Chinese medicine combined with radiation therapy is a promising and innovative treatment for non-small cell lung cancer.These results establish a theoretical foundation for further clinical development of ISL as a potential radiosensitizer option.

Objective:To explore the feasibility and clinical efficacy of prone transpsoas lateral interbody fusion (PTP LIF) combined with posterior pedicle screw fixation for the treatment of lumbar degenerative diseases in the prone position.Methods:A total of 23 patients who underwent LLIF in the prone position at the First People's Hospital of Yunnan Province between March 2023 and October 2023 were retrospectively analyzed. The cohort comprised 9 males and 14 females, with a mean age of 55.5±8.8 years (range, 41-70 years). The clinical diagnoses included intervertebral disc herniation with endplate inflammation (3 cases), lumbar spinal stenosis (13 cases), lumbar spondylolisthesis (5 cases), and lumbar instability (2 cases). The surgical segments involved L 3, 4 (15 cases), L 4, 5 (6 cases), and L 3-L 5 (2 cases), with 21 cases involving a single segment and 2 cases involving double segments. The disc height and lumbar lordosis Angle before and after surgery were compared. Lower back pain was evaluated using the visual analogue scale (VAS), while lumbar spine function was assessed via the Oswestry Disability Index (ODI). Clinical efficacy was evaluated according to the modified MacNab criteria at the last follow-up. Results:All surgeries were successfully completed. The operation time was 120.2±21.4 min (range, 90-175 min), intraoperative blood loss was 131.1±40.8 ml (range, 60-200 ml), and the hospital stay was 6.2±1.6 days (range, 4-10 days). Follow-up was obtained for all 23 cases, with the follow-up time being 9.6±2.2 months (range, 6-13 months). One case of endplate damage occurred during surgery, two cases of transient psoas muscle weakness occurred postoperatively, and one case of lower limb pain and numbness was reported; no cases of wound infection or delayed healing were observed. The postoperative disc height improved compared to preoperative (6.8±1.9 mm; F=66.618, P<0.001). There was no statistically significant difference between 3 months postoperative (11.1±1.2 mm) and immediately postoperative (12.2±1.2 mm; P>0.05), but there was a statistically significant difference between the last follow-up (10.7±1.1 mm) and immediately postoperative ( P<0.05). The postoperative lumbar lordosis angle improved compared to preoperative (35.3°±5.4°; F=19.465, P<0.001), with no statistically significant difference between 3 months postoperative (44.1°±5.4°) and immediately postoperative (47.8°±6.6°; P>0.05), but there was a statistically significant difference between the last follow-up (43.2°±5.3°) and immediately postoperative ( P<0.05). The postoperative VAS score improved compared to preoperative (6.3±1.1 points; F=79.931, P<0.001), and the last follow-up (1.1±1.1 points) showed further improvement compared to 3 months postoperative (1.7±1.4 points; P<0.05). The postoperative ODI improved compared to preoperative (69.9%±7.4%; F=592.392, P<0.001), with 3 months postoperative (23.1%±3.1%) showing improvement compared to 1 month postoperative (29.2%±3.1%), and the last follow-up (17.5%±3.6%) showing further improvement compared to 3 months postoperative ( P<0.05). At the last follow-up, the modified MacNab criteria were: excellent in 16 cases, good in 5, fair in 2, with an excellent and good rate of 91% (21/23); 7 cases of cage subsidence were observed, with no cases of internal fixation loosening. Conclusion:PTP LIF combined with pedicle screw fixation for the treatment of lumbar degenerative diseases is safe and effective, with satisfactory short-term postoperative outcomes.
