Based on standard sampling for Bufonis Venenum, this study analyzed the effect of the origin, and body weight and gender of Bufo bufo gargarizans on the quality of Bufonis Venenum. To be specific, mass spectrometry(MS) and the content determination methods in Chinese Pharmacopoeia(2020) were adopted. First, MS was performed on 76 Bufonis Venenum samples collected from 40 cities/counties in 17 provinces/autonomous regions which were derived from B. bufo gargarizans and B. melanostictus. Based on content determination, the body weight and gender of B. bufo gargarizans, which influenced the quality of Bufonis Venenum, were evaluated. Multivariate statistical analysis suggested huge difference in the material basis of the medicinal material derived from B. bufo gargarizans and B. melanostictus, and 9 differential compounds were identified. The content of components specified in Chinese Pharmacopoeia was higher in the medicinal material derived from B. bufo gargarizans than in the medicinal material derived from B. melanostictus. The content of the components specified in Chinese Pharmacopoeia was low in Bufonis Venenum derived from heavy B. bufo gargarizans, and higher in the Bufonis Venenum produced by male B. bufo gargarizans than in that produced by female B. bufo gargarizans irrespective of time and geographic location. In summary, this study provide new ideas and reference for the quality control of Bufonis Venenum, collection and processing of Bufonis Venenum, artificial breeding of B. bufo gargarizans, and biosynthesis mechanism of Bufonis Venenum.

The Chansu injection (CSI), a sterile aqueous solution derived from Chansu, is applied in clinical settings to support antitumor and anti-radiation treatments. CSI's principal active components, bufadienolides (≥90%), demonstrate potential effects on pancreatic cancer (PDAC), but their underlying mechanisms remain unclear. This study aimed to elucidate the antitumor effects and pathways associated with CSI in PDAC.

Article Synopsis
- Tumor-associated macrophages (TAMs) play a significant role in cancer progression, but the impact of liver macrophages (Kupffer cells or KCs) on hepatocellular carcinoma (HCC) is not well understood.
- This study uncovers how exosomes from HCC cells convert KCs into TAMs via an IL6-JAK1-ACAP4 signaling pathway, enhancing HCC metastasis.
- The research also highlights bufalin, a compound that inhibits JAK1, preventing the phosphorylation of ACAP4 and potentially reducing HCC cell migration and metastasis, suggesting its therapeutic promise.

Background: Bufonis Venenum (BV) is a traditional animal-based Chinese medicine with therapeutic effects against cancer. However, its clinical use is significantly restricted due to associated cardiovascular risks. BV's value in China's market is typically assessed based on "content priority," focusing on indicator components.

Bufadienolides and indolealkylamines, the primary active components in Bufonis venenum, have rapid clearance from the body with a short half-life, leading to low bioavailability. Moreover, Bufadienolides and indolealkylamines are associated with serious adverse effects. In order to reduce the toxicities, minimize the adverse effects and simultaneously load lipophilic bufadienolides and hydrophilic indolealkylamines with satisfactory drug loading and encapsulation rate, we prepared Bufonis venenum extract-liposomes (BVE-LP).
