RESUMEN
Inflammation， the basic pathological process of many diseases， can occur in various tissues and organs of the body and cause many diseases including cancer. So far， there are thousands of anti-inflammatory drugs on the market， but most of these drugs have adverse reactions of gastrointestinal injury， and can even cause greater damage to the body. In recent years， the research on the repurpose of Chinese medicine is in the ascendant， and the innovative research on the specific antimalarial drug artemisinin has attracted extensive attention from scholars in China and abroad. Artesunate is a water-soluble derivative of artemisinin， which has the characteristics of quick effect and low toxicity. In addition to its significant therapeutic effect on malaria， artesunate also has a potential anti-inflammatory effect. In this review， the anti-inflammatory effect and mechanism of artesunate were elaborated in detail by consulting the relevant literature. It was found that artesunate had good anti-inflammatory effects in the respiratory system， liver injury， osteoarthritis， dermatitis， kidney inflammation， colitis， neuroinflammation， and even in novel coronavirus disease 2019 （COVID-19）. It was concluded that artesunate mainly participated in apoptotic signal transduction， mediated immune regulation， and improved oxidative stress to play an anti-inflammatory role by acting on nuclear factor-κB （NF-κB）， nuclear factor E2-related factor 2 （Nrf2）， phosphatidylinositol-3 kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR）， Toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/tumor necrosis factor receptor-associated factor 6 （TRAF6）， high mobility group box 1 （HMGB1）/receptor for advanced glycation endproduct （RAGE）， and other pathways. Through the review of the anti-inflammatory effect and mechanism of artesunate， it is expected to provide a reference for the application of artesunate in inflammation resistance and further development and utilization of artesunate in the future.
RESUMEN
OBJECTIVE To study the absorbed components of Xiebai powder in blood. METHODS UPLC-Q-TOF-MS/MS method was adopted. SD rats were randomly divided into blank group and administration group ，with 10 rats in each group. Blank group was given water intragastrically ，and administration groups were given 2 g/mL（by the amount of crude drug ）Xiebai powder solution intragastrically. Administration volume was 11.3 mL/kg，twice a day for 3 days. One point five hours after last administration，blood was taken from the abdominal aorta of each rat ，the serum was processed to obtain the supernatant for analysis；the relevant data in positive and negative ion mode were collected ，and the absorbed components of Xiebai powder in blood were analyzed and identified by using self-built secondary mass spectrometry database and consulting the relevant literature. RESULTS Totally 17 components from Xiebai powder were identified ，among which 6 components came from sovereign Moru salba，7 from minister Cortex Lycii ，12 from assistant Glycyrrhiza uralensis ，i.e. kukoamine A ，chlorogenic acid ，tachiogroside B，astringin，neoglycyrrhizin，glycyrrhizin，azelaic acid ，isoglycyrrhizin，glycyroside，anthocyanin，sebacic acid ，parthenolide， anthocyanin，18β-glycyrrhetinic acid ，6-gingerol，palmitoamide，erucamide. These compounds were mainly flavonoids ，alkaloids and organic acids. CONCLUSIONS In this study ，17 absorbed components of Xiebai powder in blood are preliminarily determined，which are consistent with the effect of Xiebai powder. They may be the pharmacodynamic substances of Xiebai powder.
RESUMEN
Malaria is a serio us and life-threatening infectious disease that has a profound impact on human life. Artemisinin is still the first-line drug for clinical antimalarial treatment recommended by the World Health Organization. The antimalarial activity of artemisinin is mainly reflected in the peroxide bridge structure. Artemisinin-based combination therapy （ACT）is the first-line treatment for malaria in many countries. ACT mainly include artemether-lumefantrine ，artesunate-amodiaquine and dihydroartemisinin- piperaquine，etc. Compared with artemisinin monotherapy ，ACT has the advantages of shortening the length of hospital stay ， speeding up parasite clearance ，and saving economic costs ，etc. However ，there are still problems such as drug resistance. This article reviews the application status ，advantages and disadvantages of ACT at home and abroad in recent years ，in order to provide ideas for the subsequent screening of long-acting adjuvant antimalarial drugs in ACT and to solve the problem of drug resistance.
RESUMEN
Objective To investigate the effect of hirudo micropowder on inflammatory factors in rats with cerebral ischemia-reperfusion injury.Methods Rats were randomly divided into sham-operation group,model group,coarse powder hirudo group,high-,middle-and low-dose micropowder hirudo groups.The corresponding drugs were given to the rats for 10 days by intragastric administration.Then middle cerebral artery occlusion(MCAO) model was made by suture method.The changes of inflammatory factors were observed.Results The level of intercellular adhesion molecule 1(ICAM-1) in high-dose micropowder hirudo group was lower than that in coarse powder hirudo group,and the level of platelet-derived growth factor(PDGF) in middle-and high-dose micropowder hirudo groups was also lower than that in coarse powder hirudo group obviously(P
