Article Abstract
Acanthopanacis cortex (the dried root bark of Acanthopanax gracilistylus W. W. Smith) has been used for the treatment of rheumatic diseases in China for over 2000 years. Four previously undescribed lignans (1-4) and 12 known lignans (5-16) were isolated from Acanthopanacis cortex. In this study, the inhibitory activities of compounds 1-16 against neutrophil elastase (NE), cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) are reported. The results show that compounds 1-16 exhibit weak inhibitory activities against NE and COX-1. However, compounds 2, 6-8 and 13-16 demonstrate better COX-2 inhibitory effects with IC values from 0.75 to 8.17 μΜ. These findings provide useful information for the search for natural selective COX-2 inhibitors.

Article Synopsis
- The study looked at how effective pharmacopuncture (PA) was in enhancing lipid profiles for patients already on statin medications.
- A retrospective analysis of 59 patients was conducted, where PA was administered using an herbal solution at an acupoint for 12 to 16 weeks.
- Results showed significant reductions in total cholesterol and LDL levels, as well as an increase in HDL levels, with men showing greater improvement than women, suggesting PA could be an effective complementary treatment alongside statins.

(PC), (AC), and (LC), as traditional Chinese medicines, are all dried root bark, presented in a roll, light and brittle, easy to break, have a fragrant scent, etc. Due to their similar appearances, it is tough to distinguish them, and they are often confused and adulterated in markets and clinical applications. To realize the identification and quality control of three herbs, in this paper, Ultra Performance Liquid Chromatography-Quadrupole Time of Flight Mass Spectrometry Expression (UHPLC-QTOF-MS) combined with chemometric analysis was used to explore the different chemical compositions.
