Objective:To investigate the involvement of endothelial cells(ECs)-derived exosomes in the antiapoptotic effect of Danhong Injection(DHI)and the mechanism of DHI-induced exosomal protection against postinfarction myocardial ***:A mouse permanent myocardial infarction(MI)model was established,followed by a 14-day daily treatment with DHI,DHI plus GW4869(an exosomal inhibitor),or *** saline(PBS)-induced ECs-derived exosomes were isolated,analyzed by miRNA microarray and validated by droplet digital polymerase chain reaction(ddP CR).The exosomes induced by DHI(DHI-exo),PBS(PBS-exo),or DHI+GW4869(GW-exo)were isolated and injected into the peri-infarct zone following *** protective effects of DHI and DHI-exo on MI hearts were measured by echocardiography,Masson's trichrome staining,and TUNEL apoptosis *** Western blotting and quantitative reverse transcription PCR(qR T-PCR)were used to evaluate the expression levels of miR-125b/p53-mediated pathway components,including miR-125b,p53,Bak,Bax,and caspase-3 ***:DHI significantly improved cardiac function and reduced infarct size in MI mice(Plished by the GW4869 *** promoted the exosomal secretion in ECs(Pling(P<0.05).Remarkably,treatment with DHI and DHI-exo attenuated apoptosis,elevated miR-125b expression level,inhibited capsase-3 activity,and down-regulated the expression levels of proapoptotic effectors(p53,Bak,and Bax)in post-MI hearts,whereas these effects were blocked by GW4869(P<0.05 or P<0.01).Conclusion:DHI and DHI-induced exosomes inhibited apoptosis,promoted the miR-125b expression level,and regulated the p53

Hypobaric hypoxia (HH) exposure can cause serious brain injury as well as life-threatening cerebral edema in severe cases. Previous studies on the mechanisms of HH-induced brain injury have been conducted primarily using non-primate animal models that are genetically distant to humans, thus hindering the development of disease treatment. Here, we report that cynomolgus monkeys (Macaca fascicularis) exposed to acute HH developed human-like HH syndrome involving severe brain injury and abnormal behavior. Transcriptome profiling of white blood cells and brain tissue from monkeys exposed to increasing altitude revealed the central role of the HIF-1 and other novel signaling pathways, such as the vitamin D receptor (VDR) signaling pathway, in co-regulating HH-induced inflammation processes. We also observed profound transcriptomic alterations in brains after exposure to acute HH, including the activation of angiogenesis and impairment of aerobic respiration and protein folding processes, which likely underlie the pathological effects of HH-induced brain injury. Administration of progesterone (PROG) and steroid neuroprotectant 5α-androst-3β,5,6β-triol (TRIOL) significantly attenuated brain injuries and rescued the transcriptomic changes induced by acute HH. Functional investigation of the affected genes suggested that these two neuroprotectants protect the brain by targeting different pathways, with PROG enhancing erythropoiesis and TRIOL suppressing glutamate-induced excitotoxicity. Thus, this study advances our understanding of the pathology induced by acute HH and provides potential compounds for the development of neuroprotectant drugs for therapeutic treatment.

Background Hand, foot, and mouth disease (HFMD) is a common infectious disease in childhood caused by an enterovirus (EV), and which is principally seen in children under 5 years of age. To promote diagnostic awareness and effective treat-ments, to further standardize and strengthen the clinical management and to reduce the mortality of HFMD, the guidelines for diagnosis and treatment have been developed. Methods National Health Commission of China assembled an expert committee for a revision of the guidelines. The com-mittee included 33 members who are specialized in diagnosis and treatment of HFMD. Results Early recognition of severe cases is utmost important in diagnosis and treatment of patients with HFMD. The key to diagnosis and treatment of severe cases lies in the timely and accurate recognition of stages 2 and 3 of HFMD, in order to stop progression to stage 4. Clinicians should particularly pay attention to those EV-A71 cases in children aged less than 3 years, and those with disease duration less than 3 days. The following indicators should alert the clinician of possible deterioration and impending critical disease: (1) persistent hyperthermia;(2) involvement of nervous system;(3) worsening respiratory rate and rhythm;(4) circulatory dysfunction;(5) elevated peripheral WBC count;(6) elevated blood glucose and (7) elevated blood lactic acid. For treatment, most mild cases can be treated as outpatients. Patients should be isolated to avoid cross-infection. Intense treatment modalities should be given for those severe cases. Conclusion The guidelines can provide systematic guidance on the diagnosis and management of HFMD.
