[Cardiovascular complications in malaria: a review].

Malaria, one of the major global public health events, is a leading cause of mortality and morbidity among children and adults in tropical and subtropical regions(mainly in sub-Saharan Africa), threatening human health. It is well known that malaria can cause various complications including anemia, blackwater fever, cerebral malaria, and kidney damage. Conventionally, cardiac involvement has not been listed as a common reason affecting morbidity and mortality of malaria, which may be related to ignored cases or insufficient diagnosis.

Shengmai Yin alleviated plaque vulnerability and ischemic myocardial damage in diesel exhaust particle-aggravated atherosclerosis with myocardial ischemia.

Exposure to diesel exhaust particles (DEP) increases the risk of ischemic heart disease, especially heart attacks and ischemic/thrombotic strokes. Shengmai Yin (SMY) is a traditional Chinese medicine used to treat coronary heart disease. The aim of this study was to determine the protective role of SMY and the mechanism by which SMY affects DEP-induced cardiovascular injury.

Aggravation of Myocardial Ischemia upon Particulate Matter Exposure in Atherosclerosis Animal Model.

The health problems caused by air pollution (especially particulate pollution) are getting more and more attention, especially among cardiovascular disease patients, which aggravates complicated disorders and causes poor prognosis. The simple myocardial ischemia (MI) or particulate matter (PM) exposure model is unsuitable for such studies of diseases with multiple causes. Here, a method for constructing a composite model combining PM exposure, atherosclerosis, and myocardial ischemia has been described.

Combined Transcriptome and Proteome Profiling for Role of pfEMP1 in Antimalarial Mechanism of Action of Dihydroartemisinin.

Malaria parasites induce morphological and biochemical changes in the membranes of parasite-infected red blood cells (iRBCs) for propagation. Artemisinin combination therapies are the first-line antiplasmodials in countries of endemicity. However, the mechanism of action of artemisinin is unclear, and drug resistance decreases long-term efficacy.

Artesunate and Tetramethylpyrazine Exert Effects on Experimental Cerebral Malaria in a Mechanism of Protein -Nitrosylation.

Cerebral malaria (CM) is caused by , resulting in severe sequelae; one of its pathogenic factors is the low bioavailability of nitric oxide (NO). Our previous study suggested that the combination of artesunate (AS) and tetramethylpyrazine (TMP) exerts an adjuvant therapeutic effect on the symptoms of experimental CM (ECM) and that NO regulation plays an important role. In the present study, we further verified the effects of AS+TMP on cerebral blood flow (CBF) and detected NO-related indicators.

The Protective Effects of Shengmai Formula Against Myocardial Injury Induced by Ultrafine Particulate Matter Exposure and Myocardial Ischemia are Mediated by the PI3K/AKT/p38 MAPK/Nrf2 Pathway.

Ultrafine particulate matter (UFPM) induces oxidative stress (OS) and is considered to be a risk factor of myocardial ischemia (MI). Shengmai formula (SMF) is a traditional Chinese medicine with antioxidant properties and has been used to treat cardiovascular diseases for a long time. The aim of this study was to explore the protective role of SMF and the mechanism by which it prevents myocardial injury in UFPM-exposed rats with MI.

Shenlian extract protects against ultrafine particulate matter-aggravated myocardial ischemic injury by inhibiting inflammation response via the activation of NLRP3 inflammasomes.

Air pollution is a growing public health burden associated with several negative health effects, especially cardiovascular disease. Shenlian extract (SL), a traditional Chinese medicine, has the effects of clearing heat-toxin and promoting blood circulation for removing blood stasis, and it has long been used to treat cardiovascular diseases and atherosclerosis. This study explored the underlying action mechanism of SL against ultrafine particle-induced myocardial ischemic injury (UFP-MI) through network pharmacology prediction and experimental verification.

[Potential therapies for COVID-19 cardiovascular complications using artemisinin and its derivatives intervene based on its cardiovascular protection].

Corona virus disease 2019(COVID-19) has brought untold human sufferings and economic tragedy worldwide. It causes acute myocardial injury and chronic damage of cardiovascular system, which has attracted much attention from researchers. For the immediate strategy for COVID-19, "drug repurposing" is a new opportunity for developing drugs to fight COVID-19.

Synergistic Effect of Combined Artesunate and Tetramethylpyrazine in Experimental Cerebral Malaria.

Intravenous artesunate is effective against cerebral malaria (CM), but high mortality and neurological sequelae in survivors are inevitable. We investigated the effect of combined artesunate and tetramethylpyrazine using mouse models of experimental cerebral malaria (ECM). Artesunate + tetramethylpyrazine reduced microvascular blockage and improved neurological function, including the rapid murine coma and behavior scale (RMCBS), leading to improved survival and reduced pathology in ECM.

[Method for rapid synchronization of different growth cycles of Plasmodium falciparum in vitro and application in differential gene expression profile of 3D7 after dihydroartemisinin treatment].

Plasmodium culture in vitro is often used as an antimalarial drug evaluation model, but the lifecycle of P. falciparum culture in vitro tends to be disordered, which affects the research and evaluation of antimalarial drug mechanism in vitro. By combining magnetic bead separation method with sorbitol synchronization method, a synchronization method was constructed to quickly acquire different lifecycles of P.
