ObjectiveTo systematically evaluate the content differences of 4 components in Leonuri Herba granules, reveal the quality fluctuation patterns of products from the same and different manufacturers, providing scientific basis for the optimization of production process and quality control. MethodsHigh performance liquid chromatography-diode array detector-charged aerosol detector(HPLC-DAD-CAD) was employed to determine the contents of 4 components(syringic acid, leonurine hydrochloride, ferulic acid, and stachydrine hydrochloride) in samples from 19 manufacturers(53 batches, 159 boxes). Additionally, fingerprint profiles were constructed, and the fingerprint dissimilarity(PS) and relative standard deviation(RSD) of different samples from the same manufacturer were calculated. A principal component analysis(PCA) model was established with PS and the RSD values of the 4 components as variables to classify the manufacturers. Finally, samples from 5 manufacturers(M1-M5) covering three consistency groups were selected to calculate three quality consistency parameters, namely intra-batch consistency(PA), inter-batch consistency(PB), and PS. Then, PCA was performed with PA, PB, and PS of these 5 manufacturers as variables. ResultsThe average total content of the 4 index components per bag across the 19 manufacturers ranged from 41.10 mg to 97.54 mg. Among them, the content of stachydrine hydrochloride(a pharmacopoeial quality control component) was 32.46-72.70 mg per bag, all meeting the requirements of the 2025 edition of the Pharmacopoeia of the People's Republic of China, with RSD of 1.7%-17.1%. The content ranges of the other 3 components were as follows:syringic acid of 1.43-41.92 mg per bag, leonurine hydrochloride of 0.67-11.85 mg per bag, and ferulic acid of 0.11-3.81 mg per bag. Notably, leonurine hydrochloride exhibited the most significant content fluctuation among samples from the same manufacturer(RSD of 4.8%-59.2%). PCA results showed that the 19 manufacturers could be classified into 3 categories. Samples from 8 manufacturers(M2, M6, M7, M8, M10, M15, M17, M18) demonstrated relatively high consistency, five manufacturers(M3, M9, M12, M13, M14) showed moderate consistency, six manufacturers(M1, M4, M5, M11, M16, M19) exhibited low consistency. The two methods yielded consistent classification results for the 5 representative manufacturers, verifying the reliability of the proposed method. Among these, manufacturer M2 showed the best quality consistency and the highest total content of indicator components among M1-M5. ConclusionThe HPLC-DAD-CAD multi-detector hyphenation technology established in this study enables the accurate detection of 4 components in Leonuri Herba granules. Significant differences in the total content of these four components are observed among products from 19 manufacturers. The application of 2 consistency evaluation methods combined with PCA can effectively classify their consistency into 3 categories, and the classification results of the 2 methods are highly consistent. This study provides scientific basis for the process optimization and quality standard improvement of Leonuri Herba granules.

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.

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.

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.

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 the effect of different drying conditions on the appearance and intrinsic quality indicators of Pinelliae Rhizoma for screening suitable drying conditions, so as to provide reference for its standardized production and quality evaluation. MethodsDifferent dried samples of Pinelliae Rhizoma were prepared by lime-assisted sweating method and intermittent drying method. Visual analysis was employed to measure the color brightness values(L*) of the surface, cross-section and powder of the samples, texture analyzer was used to determine the hardness of the samples under different drying conditions. The total starch content was calculated by measuring the contents of amylose and amylopectin in the samples with ultraviolet-visible spectroscopy. High performance liquid chromatography(HPLC) was used to determine the contents of seven nucleoside components(uracil, hypoxanthine, uridine, inosine, guanosine, β-thymidine and adenosine) in the samples. Pearson correlation analysis was conducted to explore the correlation between the external characteristics and intrinsic indicators of the different dried samples. Principal component analysis(PCA) was used to comprehensively rank the data of various indicators, and partial least squares-discriminant analysis(PLS-DA) was used to screen differential components with variable importance in the projection(VIP) value>1. Furthermore, the difference between the optimal drying condition for Pinelliae Rhizoma and the traditional sun-drying method was explored by independent samples t-test. ResultsWith the increase of temperature, the color of the intermittently dried samples gradually deepened, while their hardness gradually decreased. Concurrently, the contents of extract, total starch, uridine and adenosine exhibited an upward trend, whereas the contents of uracil, hypoxanthine and inosine displayed a downward trajectory. Compared with the intermittent drying group, the content of extract in the samples subjected to lime-assisted sweating increased. With the increase of lime dose, the hardness and the total content of nucleoside components in the samples showed a downward trend, while the total starch content showed an upward trend. Correlation analysis showed that the comprehensive score of L* was negatively correlated with the contents of uracil, hypoxanthine and inosine, and positively correlated with the contents of uridine, guanosine and adenosine. Hardness was negatively correlated with adenosine content, and positively correlated with the contents of inosine, uracil and hypoxanthine. Through comprehensive consideration and comprehensive score of principal components, the method of 5% lime-mixed sweating for 6 days emerged as the top-ranking approach. Except for the extract, the results of independent samples t-test showed that there was no significant difference between the 5% lime-mixed sweating for 6 days and the traditional sun-drying in terms of other content indicators. ConclusionThe whiteness and firmness of Pinelliae Rhizoma exhibit significant correlations with its chemical composition, while uridine, uracil, guanosine, adenosine and inosine are the key constituents responsible for the quality difference of Pinelliae Rhizoma under different drying conditions. The lime-assisted sweating method optimized in this study can be proposed as a viable alternative to the traditional sun-drying method. This method not only ensures the quality of the medicinal material but also effectively reduces the drying time and prevents mold contamination, which provides a valuable reference for the standardization of drying conditions and the establishment of quality evaluation criteria for Pinelliae Rhizoma.
