pH-Responsive Artesunate Polymer Prodrugs with Enhanced Ablation Effect on Rodent Xenograft Colon Cancer.

Purpose: In this study, pH-sensitive poly(2-ethyl-2-oxazoline)-poly(lactic acid)-poly(β-amino ester) (PEOz-PLA-PBAE) triblock copolymers were synthesized and were conjugated with an antimalaria drug artesunate (ART), for inhibition of a colon cancer xenograft model.

Dihydroartemisinin Regulates the Th/Treg Balance by Inducing Activated CD4+ T cell Apoptosis via Heme Oxygenase-1 Induction in Mouse Models of Inflammatory Bowel Disease.

Dihydroartemisinin (DHA) is a derivative of the herb that has prominent immunomodulatory activity; however, its underlying mechanism remains elusive. Inflammatory bowel disease (IBD) is an idiopathic inflammatory condition characterized as an autoimmune disorder that includes dysfunctions in the T helper (Th)/T regulatory cell (Treg) balance, which normally plays pivotal roles in immune homeostasis. The aim of this study was to explore the potential of DHA to ameliorate IBD by restoring the Th/Treg cell balance.

[Basic research of fibrosis on atherosclerotic plaque stability and related drug application].

In the background of the high incidence and high mortality of cardiovascular diseases,atherosclerosis is the main pathological feature of cardiovascular diseases and the core pathological basis for disease progression. In the evolution of atherosclerotic plaques,the rupture of unstable plaques,plaque shedding and formation of thrombosis are the most dangerous parts. In this process,the formation of plaque fibrosis is the core mechanism regulating plaque stability.

[Research initiative of new thought on "main effect" of TCM formulae--new thinking on mechanism of compound action and compatibility mechanism of Chinese herbal compound formulae].

This article proposes a new thought on the study of "main effect" of traditional Chinese medicine (TCM) formulae. The blood concentrations of the pharmacodynamic substances of Chinese material medica（CMM）are usually very low, with lower toxic and side effects than western medicine. Therefore, according to a recent hypothesis of additive effect of multiple components for a single target, local targets in multi-component multi-target synergistic effect network of TCM may have the additive effect of similar components.

[Effect of dihydroartemisinin on permeability of human erythrocyte membrane infected plasmodium].

In view of the fact that the antimalarial effects of artemisinins are significant but the mechanism has not yet been clarified and there are many different opinions, it is possible that artemisinins can produce high anti-malarial efficacy through various mechanisms and multiple pathways. In addition, the researches on the pathogenesis of malaria "erythrocyte membrane plasmodial surface anion channel (PSAC)" in the past few years have provided more positive findings, which may confirm and discover the new antimalarial mechanism of artemisinins. This paper was as to study the effect of dihydroartemisinin (DHA) in vitro on erythrocyte membrane permeability of HB3 plasmodium infection, with using the mechanism of 5% sorbitol can be used to kill the Plasmodium falciparum in red blood cell membrane selectively, the effectual difference of sorbitol on the killing of P.
