ObjectiveTo establish the fingerprints of 15 batches of Hengzhi Kechuan capsules, to quantitatively analyze 10 index components, and to evaluate the quality uniformity of samples from different batches. MethodsThe fingerprints and quantitative analysis of Hengzhi Kechuan capsules were established by a combination method of high performance liquid chromatography coupled with diode array detector and charged aerosol detector(HPLC-DAD-CAD), adenosine, guanosine, vanillic acid, safflomin A, agarotetrol, naringin, hesperidin, militarine, ginsenoside Rb1, and glycyrrhizic acid were selected as quality attribute indexes. A total of 15 batches of Hengzhi Kechuan capsules from 2022 to 2024(3 boxes per batch) were qualitatively and quantitatively analyzed, and the quality uniformity level of the manufacturers was characterized by parameters of intra-batch consistency(PA) and inter-batch consistency(PB). The homogeneity and difference of quality attribute indexes of samples from different years were analyzed by heatmap clustering analysis. ResultsHPLC fingerprints and quantitative method of Hengzhi Kechuan capsules were established, and the methods could be used for qualitative and quantitative analysis of this preparation, which was found to be stable and reliable by method validation. The similarity of fingerprints of 15 batches of samples was 0.887-0.975, a total of 13 common peaks were calibrated, and 10 common peaks were designated, all of which were quality attribute index components. The results of quantitative analysis showed that the contents of the above 10 ingredients in the samples were 0.038-0.078, 0.115-0.251, 0.007-0.018, 0.291-0.673, 0.122-0.257, 0.887-1.905, 1.841-3.364, 1.412-2.450, 2.207-3.112, 0.650-1.161, respectively. And the contents of ginsenoside Rb1 and glycyrrhizic acid met the limit requirements in the 2020 edition of Chinese Pharmacopoeia. For the samples from 15 batches, the PA values of the 10 index components were all <10%, indicating good intra-batch homogeneity, and the PB values ranged from 33.86% to 92.97%, suggesting that the inter-batch homogeneity was poor. Heatmap clustering analysis showed that the samples from different years were clustered into separate categories, and adenosine, guanosine, safflomin A, naringin, hesperidin and agarotetrol were the main differential components. ConclusionThe intra-annual quality uniformity of Hengzhi Kechuan capsules is good and the inter-annual quality uniformity is insufficient, which may be related to the quality difference of Pinellinae Rhizoma Praeparatum, Carthami Flos, Citri Sarcodactylis Fructus, Citri Reticulatae Pericarpium, Aquilariae Lignum Resinatum, Citri Fructus, etc. In this study, the fingerprint and multi-indicator determination method of Hengzhi Kechuan capsules was established, which can be used for more accurate and efficient quality control and standardization enhancement.

Panvascular disease, with vascular diseases as the common pathological feature, is mainly manifested as atherosclerosis. Panvascular disease mainly affects the important organs of the heart, brain, kidney, and limbs. It is one of the leading causes of death for Chinese residents at present. Previously, due to the narrow branches of disciplines, too much attention was paid to local lesions, resulting in the neglect of panvascular disease as a systemic one. The fact that panvascular disease has overall pathology and comprehensive and individualized treatment strategies, makes the disease highly compatible with the principles of holism concept and syndrome differentiation and treatment in traditional Chinese medicine (TCM). It is believed that blood stasis is the core pathogenesis of atherosclerosis and is involved in the whole process of atherosclerosis. The theories of ''blood vessel'', ''meridians'', ''visceral manifestation'', and ''organs-meridians'' in TCM are helpful to comprehensively understand the complexity of panvascular diseases. Moreover, those theories can provide systematic treatment strategies. The TCM syndromes of panvascular diseases evolve from ''phlegm, stasis, stagnation, and deficiency''. Panvascular arteriosclerosis is related to the syndrome of ''stasis and phlegm'', and the treatment mainly promotes blood circulation and removes phlegm. There are different specific drugs and mechanisms of action for coronary atherosclerosis, cerebral atherosclerosis, and renal artery atherosclerotic stenosis. Panvascular venous lesions are related to the syndrome of ''deficiency and stasis'' in TCM, and the TCM treatment mainly invigorates Qi and promotes blood circulation, which can inhibit venous thrombosis, improve venous ulcers, and resist venous endothelial damage. Panvascular microcirculatory lesions are inseparable from the ''stagnation and stasis'' in TCM, and the treatment mainly promotes Qi and dredges collaterals, which has a good effect on coronary microvascular lesions, diabetic microvascular lesions, pulmonary microvascular lesions, and pancreatic microvascular lesions. Panvascular lymphatic lesions are related to the syndrome of ''water and stasis'' in TCM. The treatment method focuses on promoting blood circulation and water excretion, which can promote lymphangiogenesis and enhance lymphatic reflux. In addition, the combination of TCM and modern technology, especially the application of artificial intelligence, can improve the efficiency of early identification and personalized treatment, resulting in early screening and comprehensive management of panvascular diseases. Therefore, TCM will play a vital role in the prevention and treatment of panvascular diseases.

Paraganglioma(PGL)is an extra-adrenal catecholamine-secreting endocrine tumor. We reported a young female patient who was admitted to the hospital with right flank pain and diagnosed with right retroperitoneal PGL with Mayo Ⅳ inferior vena cava tumor thrombus(double tumor thrombus). After multidisciplinary consultation,right retroperitoneal PGL resection,right nephrectomy,inferior vena cava Mayo Ⅳ tumor thrombus resection and reconstruction were performed. Postoperative pathology showed that the primary tumor and inferior vena cava tumor thrombus was consistent with PGL. Genetic testing revealed a heterozygous germline nonsense mutation at c.69_70delinsTT(p.Q24*)locus of the SDHB gene in the patient. His mother was a carrier of the gene,but his father and sister did not carry the mutation. The patient recovered smoothly after surgery.

ObjectiveTo explore quality difference factors of Perillae Caulis based on the contents of multiple chemical components and comprehensively evaluate the quality. MethodsA total of 32 batches of Perillae Caulis samples were collected from 12 producing areas such as Hebei, Anhui and Guangdong, and their diameter range, epidermis color and producing areas were recorded. Total flavonoids, total phenols, volatile oils, 5 active components and 84 volatile components in 32 batches of samples were quantitatively or semi-quantitatively determined by colorimetry, ultra performance liquid chromatography-photodiode array detector(UPLC-PDA) and gas chromatography-mass spectrometry(GC-MS). Then the differences between the contents of these components were analyzed by principal component analysis(PCA) and non-parametric test. According to the weights of the index components determined by PCA model, entropy weight-technique for order preference by similarity to ideal solution(TOPSIS) model was constructed to evaluate the quality of Perillae Caulis with different characters and origins. ResultsThere were significant differences in the composition of Perillae Caulis with different diameters, epidermis colors and producing areas, and 9 differential components were screened out, including 6 index constituents(total flavonoids, total phenols, caffeic acid, scutellarin, rosmarinic acid and luteolin) and 3 volatile components(caryophyllene oxide, (-)-humulene epoxide Ⅱ, 14-hydroxycaryophyllene), of which 6 index constituents were higher in samples with small diameter, purple-brown epidermis and southern origin, while the contents of 3 volatile components were higher in samples with large diameter, dark-brown epidermis and northern origin. A significant difference was shown in the model scores of different diameters, epidermis colors and origins(P<0.05), and the scores of Perillae Caulis with small diameter and purple-brown epidermis from southern area, especially Guangdong, had a high score. ConclusionThere are significant differences in the composition and content of chemical constituents between different diameters, epidermal colors and production areas of Perillae Caulis, samples showing small diameter, owing purple-brown epidermis, and originating from Guangdong were of higher-quality due to their higher content of 8 key indices.

OBJECTIVE:
To reveal the effects and potential mechanisms by which synaptic vesicle glycoprotein 2A (SV2A) influences the distribution of amyloid precursor protein (APP) in the trans-Golgi network (TGN), endolysosomal system, and cell membranes and to reveal the effects of SV2A on APP amyloid degradation.
METHODS:
Colocalization analysis of APP with specific tagged proteins in the TGN, ensolysosomal system, and cell membrane was performed to explore the effects of SV2A on the intracellular transport of APP. APP, β-site amyloid precursor protein cleaving enzyme 1 (BACE1) expressions, and APP cleavage products levels were investigated to observe the effects of SV2A on APP amyloidogenic processing.
RESULTS:
APP localization was reduced in the TGN, early endosomes, late endosomes, and lysosomes, whereas it was increased in the recycling endosomes and cell membrane of SV2A-overexpressed neurons. Moreover, Arl5b (ADP-ribosylation factor 5b), a protein responsible for transporting APP from the TGN to early endosomes, was upregulated by SV2A. SV2A overexpression also decreased APP transport from the cell membrane to early endosomes by downregulating APP endocytosis. In addition, products of APP amyloid degradation, including sAPPβ, Aβ 1-42, and Aβ 1-40, were decreased in SV2A-overexpressed cells.
CONCLUSION
These results demonstrated that SV2A promotes APP transport from the TGN to early endosomes by upregulating Arl5b and promoting APP transport from early endosomes to recycling endosomes-cell membrane pathway, which slows APP amyloid degradation.

Panvascular disease is a complex systemic disorder. Research by our team has established "kidney deficiency-vascular impairment" as its core pathogenesis. Consequently, we developed a three-tiered progressive prevention and treatment strategy: early prevention phase: focuses on tonifying the kidney and reducing turbidity; mid-term control phase: focuses on tonifying the kidney and stabilizing plaque; late recovery phase: focuses on tonifying the kidney and unblocking collaterals. This targeted therapeutic protocol effectively alleviates clinical symptoms, improves biochemical markers, enhances treatment efficacy, and achieves comprehensive management throughout the disease course. This article systematically elaborates on the concept of "kidney deficiency-vascular impairment" in panvascular disease, summarizes the mechanisms of kidney-tonifying Chinese herbal medicines, aiming to provide a beneficial reference for the whole-course management of panvascular diseases.
