Résumé
Background:@#Blood purification (BP) is one of the most important rescue measures for patients with critical illness in the intensive care unit (ICU), especially for those with acute kidney injury. The purpose of this nationwide survey was to reveal the real world of current BP practice in different ICUs all over China. This study was designed to be a multi-center cross-sectional study.@*Methods:@#All adult patients (over 18 years of age), who were admitted to ICU and required BP in 35 sub-centers across China were included during 30-day survey period in 2018. Demographic characteristics and clinical data were recorded including the timing of treatment initiation, indications, modality, relative contraindication, establishment of vascular access, selection of filter/membrane, settings, anti-coagulation, executive department, complication, intake, and output.@*Discussion:@#This nationwide survey may contribute to reveal the real world of current BP practice in different ICUs all over China.@*Trial registration:@#Chinese Clinical Trial Registry, ChiCTR-EOC-17013119; http://www.chictr.org.cn/showproj.aspx?proj=22487.

Résumé
OBJECTIVE@#To investigate whether heroin can directly induce apoptosis in primary cultured cortical neurons of rat's brain.@*METHODS@#Cultured primary neurons cultures were obtained from cerebral cortex of embryo rats. After 7 days, the cells were incubated with different concentrations of heroin (purity-80%) for 24 hours. The neuronal survival was assessed by cell viability counting with fluorescent diacetate (FDA) staining. The morphological and biochemical changes were observed with Hoechst 33258 fluorescent staining and then analyzed by agarose gel electrophoresis, respectively.@*RESULTS@#After treatment with different concentrations of heroin, the neurons showed a decreased survival rate in a dose dependent manner, and there was a significant difference in the survival rate between the heroin group and the control group (P < 0.05). When exposed to different concentrations of heroin, neurons exhibited the morphological and biochemical features of apoptosis, including cell shrinkage, neurite degeneration, network disappearance, condensation and aggregation of nuclear chromatin, and the formation of DNA ladders. With the increase of heroin concentration of rat's brain more apoptotic bodies were seen.@*CONCLUSION@#Heroin can directly induce apoptosis in primary cultured cortical neurons in rat's brain.
