[Charcoal-frying process and quality markers of Sanguisorbae Radix based on hemostatic effect].

Studies have reported that the hemostatic effect of Sanguisorbae Radix(SR) is significantly enhanced after processing with charcoal. However, the standard components(tannins and gallic acid) specified in the Chinese Pharmacopeia decrease in charcoal-fried Sanguisorbae Radix(CSR), which is contrast to the enhancement of the hemostatic effect. Therefore, this study aimed to optimize the charcoal-frying process of SR based on its hemostatic efficacy and comprehensively analyze the components of SR and its processed products, thus exploring the material basis for the hemostatic effect.

[Herbalogical study on historical evolution of Juhong and Huajuhong].

In ancient times, there were two types of "Juhong" came from the tangerines(Citrus reticulata) and the pomelos(C. grandis and its cultivars), which corresponded to Juhong and Huajuhong recorded in the Chinese Pharmacopoeia respectively. In different periods, Juhong basically came from the same species and the same medicinal parts, but there were also some differences.

[Herbalogical study on Cervi Colla].

Cervi Colla, deer's gelatin, had two kinds of original sources historically, including the skin and antler of deer, known as Cervi Corii Colla(Lupijiao, LPJ) and Cervi Cornus Colla(Lujiaojiao, LJJ) respectively.LJJ is the mainstream of the market, while LPJ is only used by common people in Guizhou and Jilin etc. This article sorted out the ancient and modern literature(since Rites of the Zhou in Zhou Dynasty) on Cervi Colla and conducted the herbalogical study.

Proteomic analysis reveals the potential neuroprotective effects of tetramethylpyrazine dimer in neuro2a/APPswe cells.

Alzheimer's disease (AD) is a common neurodegenerative disease characterized by pathological processes, including abnormal amyloid deposits and filament tangles, oxidative stress, neuroinflammation, and neurotrophic insufficiency, leading to chronic and prolonged neuronal loss and cognitive deficits. Tetramethylpyrazine (TMP) is one of the main active components of , a traditional Chinese medicine widely used for brain related disease. Here, we synthesized the TMP derivative tetramethylpyrazine dimer (DTMP), and evaluated the potential mechanisms underlying its potential neuroprotective effects using the murine neuron-like cells (N2a) transfected with the human "Swedish" mutant amyloid precursor protein (N2aAPP).
