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.

ObjectiveTo investigate the relationship between solute carrier family 7 member 11 （SLC7A11） expression in esophageal squamous cell carcinoma （ESCC） and clinical prognosis， and to determine its effects on ESCC cell growth， migration， and other biological activities. MethodsSLC7A11 protein expression was measured in 310 ESCC tissues and 259 adjacent normal tissues using immunohistochemistry to statistically assess the association of SLC7A11 with clinicopathologic characteristics and prognosis in ESCC patients. The expression of SLC7A11 in ESCC cell lines was suppressed through siRNA-mediated knockdown. The specific effects of SLC7A11 knockdown on proliferation and migration were evaluated using CCK-8， clonogenic assay， and Transwell assays. Adenosine triphosphate （ATP）， lactic acid and pyruvate assays were used to measure ESCC metabolism. ResultsSLC7A11 protein expression was localized predominantly in the cytoplasm of ESCC tissues. Significantly higher SLC7A11 expression levels were observed in ESCC tissues compared to adjacent normal tissues （P<0.001）. High SLC7A11 expression was associated with poorer differentiation in patients （P<0.01）. Kaplan-Meier survival analysis demonstrated significantly shorter overall survival in patients with high SLC7A11 expression compared to those with low expression （P<0.05）. CCK-8 and colony formation assays demonstrated that the knockdown of SLC7A11 expression significantly suppressed the proliferative capacity of tumor cells （P<0.001）. Furthermore， Transwell assays revealed a marked decline in tumor cell migration capacity following SLC7A11 suppression （P<0.001）. Critically， SLC7A11 knockdown also reduced intracellular levels of ATP， lactate， and pyruvate， demonstrating that SLC7A11 modulated metabolic activity in ESCC cells（P<0.001）. ConclusionThe expression level of SLC7A11 is relatively high in ESCC and is strongly associated with poor prognosis. Silencing SLC7A11 significantly inhibits esophageal cancer cell growth and migration. SLC7A11 has the ability to regulate glucose， lactic acid and ATP metabolism levels in ESCC， thereby affecting the metabolic microenvironment of ESCC.

BACKGROUND:Autologous bone,allogeneic bone or artificial bone has been used to promote bone defect repair in the clinic,but the rate of non-healing is still high.The key is to ignore the importance of periosteum in the bone healing process.In the early stage of the project,the project team constructed an electrospinning membrane loaded with vascular endothelial growth factor to highly simulate the intramembranous osteogenesis of natural periosteum at the bone defect site,which promoted bone regeneration to a certain extent.However,the injured area often faces the dilemma of severe inflammatory response mediated by macrophages and lack of seed cells,resulting in the risk of inactivation or diffusion of delivered biological factors.Therefore,it is necessary to further optimize and coordinate the immune regulation and angiogenesis functions of biomimetic periosteum to promote bone repair.OBJECTIVE:To investigate the physicochemical properties of stem cell-engineered bionic periosteum and its role in regulating the inflammatory microenvironment to promote bone repair.METHODS:By combining L-polylactic acid-based microsol electrospinning,type Ⅰ collagen self-assembly and gel stem cell transplantation technology,a bionic periosteum(M@C-B)was constructed,in which the core layer loaded with vascular endothelial growth factor and the shell layer delivered bone marrow mesenchymal stem cells to regulate the immune microenvironment of bone defects.The physicochemical properties of the periosteum were characterized by scanning electron microscopy,transmission electron microscopy,and Fourier transform infrared spectroscopy.A co-culture system was established between the bionic periosteum and macrophages,bone marrow mesenchymal stem cells and human umbilical vein endothelial cells to explore immune regulation and in vitro osteogenic and angiogenic abilities.Finally,the osteogenic properties of the stem cell engineered bionic periosteum were further verified in a rat femoral condyle defect model.RESULTS AND CONCLUSION:(1)Transmission electron microscopy results showed that the micro-sol electrospinning(MS)formed a distinct core-shell structure.Scanning electron microscopy indicated that after the assembly of the collagen-l artificial periosteum(M@C)on the surface of the vascular endothelial growth factor-loaded micro-sol,a distinct"spider web-like"fibrous structure was deposited.Infrared spectroscopy further confirmed the successful self-assembly of collagen-l.Release experiments demonstrated that the M@C group mitigated the burst release phenomenon compared to the MS group,maintaining internal vascular endothelial growth factor activity and sustained release.(2)Live/dead cell staining and CCK-8 assay showed that bone marrow mesenchymal stem cells proliferated well and survived on three types of artificial periosteum:MS,purely aligned poly(L-lactic acid)(PLLA)surface self-assembled collagen-l artificial periosteum(PLLA@C),and vascular endothelial growth factor-loaded micro-sol fiber surface self-assembled collagen-l-bone marrow mesenchymal stem cells artificial periosteum(M@C-B).Among them,the M@C-B group had the highest number of live cells and the fastest proliferation rate.(3)Alkaline phosphatase staining,alizarin red staining,and osteopontin immunofluorescence staining showed that the PLLA@C and M@C-B groups significantly promoted osteogenic differentiation of bone marrow mesenchymal stem cells.Angiogenesis experiments demonstrated that the vascular endothelial growth factor-loaded groups(MS and M@C-B)had longer blood vessel lengths and more reticular vascular-like structures with more cross-linked nodes,with the M@C-B group being the most prominent.(4)Immunofluorescence and flow cytometry showed that artificial periosteum in the M@C-B group significantly inhibited the pro-inflammatory macrophage phenotype and promoted the polarization of macrophages towards the anti-inflammatory M2 phenotype.(5)In vivo studies further confirmed that the M@C-B group showed superior bone mineral density,trabecular thickness,relative bone volume,and trabecular spacing compared to other groups.(6)These results indicate that bone marrow mesenchymal stem cell-engineered artificial periosteum,through the rapid regulation of the bone defect immune microenvironment by the collagen-l-bone marrow mesenchymal stem cells outer phase and the sustained release of vascular endothelial growth factor by the micro-sol electrospinning core-shell structure of the inner phase,synergistically promotes bone healing.

ObjectiveTo investigate the effect of Huangqi jiuni decoction （HQJND） on acute liver injury in severely scalded rats and its possible molecular mechanism by animal experiments and modern pharmacological tools. MethodsFirstly， the rat model of sepsis was established and randomly divided into 4 groups. The normal saline group was given 1 mL of normal saline twice a day， and the traditional Chinese medicine group was given 1 mL of concentrated huangqi jiuni decoction twice a day. After 72 hours of shock， the samples were sacrificed， and then the serum liver function and （+）-haematoxylin eosin staining were performed to verify the efficacy of the drug. Sham Operation Group and sepsis group were fed normally without any special treatment. Then， network pharmacology was used to screen the targets of drugs and drug responses and predict the signaling pathways that might play a role in the treatment of diseases. Finally， fluorescence quantitative PCR （RT-qPCR） was performed to detect gene expression， Western blot （WB） was performed to detect tumor necrosis factor （TNF-α）， P65， phosphorylated P65 （P-P65）， and immunohistochemical （IHC） were performed assays to verify drug efficacy and explore the mechanism of drug treatment. ResultsSerum liver function and histopathology in rats showed that HQJND significantly improved liver function in severely burned rats. Network pharmacology screening was used to identify 353 disease-related marker genes and 286 drug targets. It was predicted that tumor necrosis/NF-NF-κB pathway （TNF/NF-NF-κB pathway） might be a key pathway for HQJND to treat acute liver injury after severe burns. The results of immunohistochemistry （IHC） showed that the staining of TNF-α in the liver of the sepsis group was more than that of the sham operation group and the traditional Chinese medicine group. The results of RT-qPCR and WB showed that the expression of TNF-α， TNFR1 and P65 proteins in the liver of rats in the sepsis group was significantly higher than that in the sham operation group and the traditional Chinese medicine group； on the contrary， the expression of TNF-α， TNFR1 and P65 proteins in the liver of rats in the sepsis group was significantly higher than that in the sham operation group and the traditional Chinese medicine group. The expression level of nuclear factor-kappa B（IκBα） was higher in the sham operation group and the traditional Chinese medicine group， indicating that drug treatment effectively inhibited the activation of the TNF/NF-κb signaling pathway. ConclusionAnimal experiments and network pharmacology results confirm that HQJND has a protective effect on acute liver injury in severely burned rats， which may be related to the inhibition of TNF/NF-κB signaling pathway.

Pan vascular disease （PVD） is a systemic vascular disorder that has become the leading cause of death among the Chinese residents， and there is currently a lack of effective systemic treatment options. Clinical practice has found that the traditional Chinese medicine （TCM） method of kidney tonification can effectively intervene in PVD and target key pathological mechanisms of PVD recognized in Western medicine. Accordingly， this paper conducts research from the following three aspects： First， it clarifies that immune dysregulation， metabolic disorders， and genetic susceptibility constitute the core pathological mechanisms of PVD in Western medicine. Typical pathological manifestations include progressive vascular endothelial injury， lipid deposition， and plaque formation， ultimately leading to multi-organ damage and dysfunction. PVD activates pathways such as the NOD-like receptor thermal protein domain-associated protein 3 （NLRP3） inflammasome， triggering immune dysregulation； it also induces disorders of mitochondrial energy metabolism， water-salt metabolism， and hormonal metabolism， synergizing with genetic susceptibility factors （e.g.， apolipoprotein E gene） to accelerate vascular homeostasis imbalance. Second， this study analyzes the intrinsic relationship between the TCM theory of "kidney deficiency" and the "immune-metabolic-genetic" axis， revealing the theoretical basis for kidney tonification in intervening PVD. The kidney stores essence， governs bones， and produces marrow， which is related to the generation and differentiation of immune cells. It regulates Qi transformation and governs water， overseeing material and energy metabolism. The kidney is the root of congenital essence and governs reproduction， closely related to genetic mechanisms. Third， by integrating modern clinical research， this study elaborates on the unique advantages and clinical value of kidney tonification in targeting the "immune-metabolic-genetic" axis of heart， brain， and kidney organs. Traditional kidney-tonifying formulas and their active ingredients improve immune-inflammatory responses， enhance material and energy metabolism homeostasis， and modulate epigenetic pathways through multiple pathways， targeting various pathways to intervene in PVD. This study systematically elucidates the scientific connotation of kidney tonification in treating PVD， providing theoretical support and practical guidance for integrated TCM-Western medicine approaches and contributing to innovation and improvement in diagnostic and treatment strategies for PVD.

As the core vehicle for preserving and transmitting traditional Chinese medicine（TCM） academic thought and clinical experience， the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine， this study conducted a comprehensive analysis of critical challenges， including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic， encompassing three dimensions of authenticity and standardization， characteristics and advantages， application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment， while aligning with modern scientific research standards， achieving a balance between individualized TCM experience and standardized evaluation. Concurrently， this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases， contributing significantly to the inheritance of TCM knowledge， evidence-based practice， and the reform of talent evaluation mechanisms.

Objective: To provide evidence for improving emergency blood supply protocols by analyzing the clinical characteristics and disease distribution of emergency transfusion patients, especially those receiving≥10 units of red blood cells (RBCs). Methods: The data of 4 157 patients who urgently applied for large-volume blood transfusion in various hospitals in Shanghai from May 2024 to April 2025 were selected and analyzed statistically. Results: Tertiary gradeA hospitals accounted for the largest proportion of total transfusion volume (U) (48.79%, 8 420/17 256.5), with no statistically significant differences in RBC transfusion volumes among hospitals of different grades (P>0.05). All blood products are most widely used in tertiary hospitals. Obstetric blood transfusion (U)(19.07%, 3 277.5/17 190.5) was the most frequent. A-mong the hospitals of patients who received emergency blood transfusion with red blood cell suspension≥10 U, tertiary gradeA hospitals also had the largest transfusion volume (U)(47.19%, 1 107/2 346). In terms of disease types, the top three diseases in terms of blood transfusion volume (U) were obstetric transfusion (24.59%, 572/2 326), digestive diseases (14.53%, 338/2 326) and tumors (14.19%, 330/2 326). Conclusion: Tertiary grade A hospitals are the main demand units for emergency blood transfusion, with pregnant women and cancer patients being the core blood-using groups. It is suggested that the safety, timeliness and sufficiency of emergency blood transfusion be guaranteed by establishing a hierarchical blood supply mechanism, formulating single-disease blood transfusion plans and promoting precise blood transfusion guided by thromboelastography.

AIM:To observe the morphological and structural changes of foveal cone photoreceptors in patients with age-related macular degeneration(ARMD)using adaptive optics scanning laser ophthalmoscopy(AOSLO)and to evaluate its application value in ARMD.METHODS:This was a retrospective cross-sectional study. Patients with ARMD who visited the Department of Ophthalmology, Army Medical Center of PLA, Army Medical University, and underwent AOSLO examination between September 2025 and October 2025 were enrolled as the experimental group(ARMD group). Age-matched individuals who underwent AOSLO examination during the same period and had either age-related cataract or pseudophakia with a normal macular region were selected as the control group(CON group). The AOSLO device was used to image a 2.4°×2.4° area of the fovea, and parameters including parafoveal cone photoreceptor density(PCPD), average inter-cell spacing, cell dispersion, and cell regularity were analyzed.RESULTS:A total of 53 participants(66 eyes)were included, comprising 24 patients(33 eyes)in the ARMD group [comprising 6 participants(6 eyes)in the intermediate ARMD group and 22 participants(27 eyes)in the late ARMD group(4 participants had one eye in the intermediate group and the other in the late ARMD group)], and 29 participants(33 eyes)in the CON group. The ARMD group included 13 males and 11 females, with a mean age of 69.36±9.79 y. The control group included 17 males and 12 females, with a mean age of 64.64±10.31 y. Compared to the CON group, the ARMD group exhibited significantly lower PCPD(31635±4887 vs 38524±3578 cells/mm2, P<0.01)and cell regularity(95.16%±0.75% vs 96.07%±0.67%, P<0.01), along with significantly greater average inter-cell spacing(4.43±0.26 vs 4.22±0.23 μm, P<0.01)and cell dispersion(20.23%±2.72% vs 16.47%±1.85%, P<0.01). Subgroup analysis within the ARMD group revealed that PCPD was significantly lower in the late ARMD subgroup(30831±4826 cells/mm2)compared to the intermediate ARMD subgroup(35254±3534 cells/mm2, P<0.05).CONCLUSION:Photoreceptor pathology in ARMD patients, as assessed by AOSLO, is characterized by decreased PCPD and cell regularity, as well as increased inter-cell spacing and dispersion. These structural alterations are closely associated with photoreceptor cell lesions. AOSLO, as a non-invasive and quantitative imaging modality, demonstrates promising application prospects in the clinical diagnosis of ARMD.
