Panvascular diseases refer to systemic vascular lesions with atherosclerosis as its common pathological basis， affecting the vascular networks of multiple organs such as the heart， brain， kidneys， limbs， and large arteries. This concept transcends the limitations of traditional classifications and promotes comprehensive vascular health management through multidisciplinary collaboration. Latent pathogenic factors play a critical role in the pathogenesis of panvascular diseases. They remain dormant within the body until finding an opportunity to manifest， which aligns closely with the characteristics of panvascular diseases， including their early covert progression and subsequent adverse vascular events. According to the ''latent pathogen'' theory， this article elucidates the pathogenesis of panvascular diseases from latent pathogen， vessel damage， and healthy Qi consumption. It posits that the disease onset involves a pathological process progressing from Qi to blood， with endothelial injury serving as the initiating factor. Disease progression encompasses changes from blood to vessels， with inflammatory responses accelerating the disease course. A comprehensive traditional Chinese medicine （TCM） based prevention and treatment system has been developed， dividing the disease course into three stages. In the early stage， pathogenic factors lurk in the vessels， primarily manifesting as abnormal lipid metabolism. In the middle stage， pathogenic factors evolve， leading to inflammatory cascade reactions. In the late stage， pathogenic factors become excessive while positive factors decline， resulting in abnormal energy metabolism. Three core therapeutic approaches-invigorating the spleen and resolving phlegm， activating blood and resolving stasis， and reinforcing healthy Qi and nourishing deficiency-have been established to address key pathological links. In conjunction with modern medical research， the mechanisms of these methods in regulating lipid metabolism， inhibiting inflammatory responses， and modulating energy metabolism to prevent and treat panvascular diseases are explained. It is anticipated that this theoretical framework will enrich the diagnostic and therapeutic thinking in TCM for panvascular diseases and provide a theoretical foundation for constructing TCM-characteristic prevention and treatment plans for panvascular diseases.

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 observe the distribution of traditional Chinese medicine （TCM） syndrome types in advanced pancreatic cancer patients， and explore the association between median survival time and different TCM syndromes and different intervention times of Chinese herbal medicine （CHM）. MethodsThe clinical data of 136 advanced pancreatic cancer patients who have received CHM for more than 3 months were collected retrospectively， including gender， age， family history， smoking history， drinking history， location of disease， lymph node metastasis， multiple distant metastasis， western medicine treatment methods， TCM diagnosis and treatment information， and survival time. The Kaplan-Meier （KM） estimator was used， and the median survival time of patients was calculated. The TCM syndrome type of each patient was judged， and the main single syndrome types and compound syndrome types were summarized. The median survival time was compared among different compound syndrome types. The patients were further divided into the group of those having received CHM ≥6 months and those having received CHM ＜6 months. Whether receiving CHM ≥6 months was taken as the grouping variable， while the matching variables were age， gender， family history， smoking history， drinking history， location of disease， lymph node metastasis， multiple distant metastasis， surgery， chemotherapy， and radiotherapy when propensity score matching was performed， and the difference in median survival time between the two groups of patients before and after matching was compared. ResultsFor 136 cases of advanced pancreatic cancer， the top five single syndromes were spleen qi deficiency， liver blood stasis， liver qi stagnation， spleen dampness， and liver heat. The main compound types were liver constraint， spleen deficiency and blood stasis syndrome， liver-gallbladder damp-heat and blood stasis syndrome， liver constraint， qi stagnation and spleen deficiency syndrome， spleen-stomach yang deficiency and blood stasis syndrome， and spleen deficiency and dampness-heat internal accumulation syndrome. The overall median survival time before and after matching was 12.47 （7.70，17.10） months and 13.77 （8.83，17.20） months， respectively， and was significantly higher in the group treated with CHM ≥ 6 months than that treated with CHM ＜6 months （P＜0.05）. Among the 136 patients before matching， the median survival time of patients with spleen deficiency and dampness-heat internal accumulation syndrome was longest ［16.23 （14.17，19.40） months］， while that of patients with spleen-stomach yang deficiency and blood stasis syndrome was the shortest ［7.33 （5.80，12.83） months］. For patients with liver constraint， spleen deficiency and blood stasis syndrome， liver-gallbladder damp-heat and blood stasis syndrome， and spleen-stomach yang deficiency and blood stasis syndrome， those having received CHM ≥ 6 months have much longer median survival time than those having received CHM ＜6 months （P＜0.05）. Among the 108 patients after matching， the median survival time of those with spleen deficiency and dampness-heat internal accumulation syndrome was the longest ［15.23 （7.67，18.27） months］， while that of spleen-stomach yang deficiency and blood stasis syndrome was the shortest ［8.80 （6.90，16.17） months］. For patients with liver-gallbladder dampness-heat and blood stasis syndrome and spleen-stomach yang deficiency and blood stasis syndrome， the median survival time was higher in the group treated with CHM ≥ 6 months treated with CHM ＜6 months （P＜0.05）. ConclusionAfter treatment with CHM， advanced pancreatic cancer patients with spleen deficiency and damp-heat internal accumulation had a better prognosis， while those with spleen-stomach yang deficiency and blood stasis had a worse prognosis. Treatment with CHM ≥ 6 months could extend the median survival of advanced pancreatic cancer patients with liver-gallbladder damp-heat and blood stasis syndrome and spleen-stomach yang deficiency and blood stasis syndrome.

According to the theory of qi channels， we explored the relationship of the method of invigorating blood and regulating tumour immunity， to provide ideas and methods for traditional Chinese medicine for regulating tumour immunity and anti-tumour metastasis. It is believed that qi channels are closely related to tumour immunity， and qi channels are equivalent to immune networks such as immune cells and immune factors with anti-tumour immunity in the tumour immune micro-environment. Combined with the physiological function and pathological characteristics of qi channels， it is proposed that the pathogenesis of qi channels-related disease due to qi channels failing to govern， blood stasis obstructing， and qi channels deficiency and stagnation as the basis for the occurrence of tumour immunosuppression and metastasis， and that qi channels constraint and stagnation as the condition for the occurrence of tumour immunosuppression and metastasis. In view of the pathomechanism of tumour immune escape caused by qi channels failing to govern， it is proposed that the therapeutic principle of regulating qi and channels to regulate tumour immunity by invigorating blood circulation method could be "performing functions when there is free flow， reaching the expectation when balanced"， and the key of treatment is to regulate qi and channels， unblock the collaterals to dispel stasis.

Objective:To investigate the biological characteristics of triple negative breast cancer (TNBC) with low expression of HER2 (HER2-low).Methods:A total of 93 TNBC cases in Shanxi Cancer Hospital from 2017 to 2019 were collected and divided into HER2-negative and HER2-low groups according to HER2 expression status. The clinicopathological features and prognostic differences between the two groups were retrospectively analyzed and compared, and genetic detection of tumor tissues was performed to clarify somatic mutation status and differences between the two groups.Results:Ninety-three patients aged 26 to 86 years were enrolled, including 60 patients in the HER2-negative group and 33 patients in the HER2-low group. The distribution of HER2-low in luminal androgen receptor (LAR) subtype (14/23, 60.87%) and non-LAR subtype (19/70, 27.14%) was significantly different ( P=0.005). There were no significant differences in age, pT stage, histological grade, infiltration mode, lymph node metastasis and survival analysis. The expression of HER2-low in the tumor was heterogeneous, including different proportions of weak, weak to moderate intensity, and incomplete to intact membrane staining. With the change of the proportion of HER2-positive cells, the different distribution of those cells in the total tumor cells was noted, including cluster, mosaic and scattered patterns. The concentration and quality of DNA extracted from 71 of the 93 samples met the requirements for making libraries, including 43 in the HER2-negative group and 28 in the HER2-low group. Genetic mutations were mainly missense mutations, single nucleotide mutations, and point mutations in which base C was replaced by base T. There was no significant difference in genes with mutation frequency>3 times between the two groups. CTNNB1 and FGFR3 genes were only mutated in HER2-low group; while ALK, CYP2D6 and FAT1 genes were only mutated in HER2-negative group. HER2-low group included 18 HER2 1+ cases and 10 HER2 2+ cases. Genes with mutation frequency>3 times between the two groups included PIK3CA, TP53, SLX4, ATM and BRCA1. The mutation frequency of PIK3CA in HER2 2+ was significantly higher than that in HER2 1+ group ( P<0.05), and SLX4 gene was only mutated in HER2 1+ group. Conclusions:There are some differences of histological morphology and genetic variation between HER2-negative group and HER2-low group, and also differences in genetic variation between HER2 1+ and HER2 2+ in HER2-low group, which are helpful for more accurate stratification of TNBC and useful for finding the therapeutic target and precise treatment of HER2-low TNBC.

Objective:This study introduces a novel approach utilizing a self-made drug delivery cannula implanted into the cerebellomedullary cistern(CMC)of rats to allow repeated administrations in conscious subjects.Methods:A self-made medication cannula is inserted through a drilled hole at the midpoint of the occipital crest of the rat's skull,de-scending along the inner wall of the occipital bone until reaching the CMC,and securing it in place with skull screws and self-curing resin.Lipopolysaccharide(LPS)is injected into the CMC to induce neuroinflammation,and the feasibility of this method is assessed using X-ray imaging,behavioral testing,and immunofluorescence staining.Results:The place-ment of the brain cannula was confirmed using X-ray film and pontamine sky blue staining.Rats in the LPS group exhib-ited a lower facial mechanical pain threshold compared to the Control group(P＜0.001),along with reduced residence time in the open field center(P＜0.01).Immunofluorescence staining revealed LPS-induced activation of caudal spinal trigeminal nucleus(SpVc)microglia.Conclusion:This method proves to be suitable for multiple administrations to the cerebellomedullary cistern of conscious rats,enabling the study of the SpVc's role in pain modulation.

Objective To explore the core acupoints and compatibility rules of acupuncture and moxibustion for epilepsy by using complex network method. Methods A prescription database was established through inclusion and exclusion criteria for searching literatures for databases from China National Knowledge Infrastructure, VIP, Wanfang, Web of Science, EMBASE, and Pubmed. SPSS Modeler software was used to analyze the frequency and correlation of acupoints, and Gephi0.10.1 software was used to establish a complex network model to explore the core acupoints and acupoint selection rules of prescriptions for epilepsy. Results Ultimately, 144 valid literatures were included, 199 prescriptions were extracted, involving 102 acupoints. Baihui acupoint had the highest frequency of use, specific acupoints were mainly Five-shu acupoint, the Eight Meridian Intersection acupoint, and the Back-shu acupoint. In selection of meridians, most acupoints were selected from governor meridian. Association rule analysis showed that Baihui-Taichong had the highest level of support and confidence. The analysis of complex network topology showed that 36 acupoints such as Baihui, Dazhui, Yaoqi and Fenglong were the core acupoints in the treatment of epilepsy by acupuncture and moxibustion. The analysis of acupoint communities revealed three major acupoint groups including governor meridian passing through treatment group, far and near matching acupoint group of the four limbs and head, and differentiation group of Zang-fu and body fluid for epilepsy treatment. Conclusion Acupoint compatibility of epilepsy by acupuncture and moxibustion should be mainly based on principle of the governor meridian combined with the differentiation of viscera and body fluid, and attention should be paid to distal-proximal point association.

Conclusions:Compared with hot towel therapy, the use of heating physiotherapy goggles can relieve ocular discomfort of MGD patients more rapidly and improve the function and status of the meibomian gland more significantly.Heating physiotherapy goggles can treat MGD safely and effectively.

Uranium is an important radioactive actinide in nature and an important nuclear material in nuclear industry. After uranium is accidentally released into the environment, it enters the body through the respiratory tract, the digestive tract, and other ways, then enters the circulation system through blood, and is finally mainly deposited in the kidney and bone, causing a certain degree of toxicity. Therefore, efficient low-toxicity chelators are an important way to reduce radionuclide pollution, radiation damage, and chemical toxicity. This article reviews uranium deposition and harm, the detoxification mechanism of uranium chelators, and the research advances in uranium chelators and points out the development trend of uranium chelators.
