Objective To track the migration and incorporation of intravenously injected, magneti?cally labeled endothelial progenitor cells ( EPCs) from mouse bone marrow into the blood vessels in a rapid?ly growing HCC model by microMR (7.0 T). Methods This study was approved by the Institutional Com?mittee on Animal Research. H22 hepatic ascitic cancer cells was directly injected into the left liver lobe of BALB/c nude mice ( n=15) . EPCs derived from bone marrow of C57BL/6 mice were isolated and cultured. The third passage EPCs were collected and labeled with 25 μg/ml superparamagnetic iron oxide ( SPIO) and poly?l?lysine (PLL) complex (SPIO?PLL). MTT assay and flow cytometry were used to evaluate the difference of growth curve and apoptosis between labeled and unlabeled EPCs. EPCs labeled with SPIO?PLL were injected into mice via tail vein in experiment group (on the 3rd day after establishing HCC model) (n=15) and control group (n=6). The signal changes of tumor (the 1st, 3rd and 7th day after transplantation) were observed by microMR. Prussian blue staining and immunohistochemistry staining of CD31 were per?formed. MRI findings were confirmed by histomorphology. Two?sample t test was used to analyze the data. Results Single tumor was showed in the liver of all mice 3 d after establishing models. Labeling with SPIO?PLL at a concentration of 25μg/ml did not alter cell growth curve ( measured by MTT assay;t=0.281, P>0.05) and cell apoptosis (analyzed by flow cytometry). The apoptosis rates of SPIO?PLL labeled and un?labled EPCs were (12.31±1.43)% and (11.57±1.24)% in early stage, and (0.55±0.07)% and (0.49± 0?05)% in late stage. No significant differences were observed between them (t=0.967, 1.060; both P>0?05) . Migration and incorporation of transplanted and labeled cells into tumor were documented with in vivo microMR as low signal intensity at the tumor periphery as early as the 3rd day after EPCs administration in preformed tumors (4/5). Prussian blue staining showed iron?positive cells at the sites corresponding to low signal intensity on MRI. The positive cells expressing CD31 existed in intratumoral and peritumoral vessels. There was no signal change in control group at all time points. Conclusions MRI can demonstrate the in?corporation of magnetic labeled mouse EPCs into the implanted hepatoma. It may be helpful for early diagno?sis and therapy of liver tumor.

Objective:To describe the incidence, diagnosis rate, treatment rate and treatment pattern of hyperkalemia, and serum potassium retesting rate among hyperkalemia patients in the emergency department.Methods:Data were derived from Military Data Center for Rational Use of Drugs. Patients who accessed emergency medical services (≥18 years old) with record(s) of serum potassium between 2015 and 2017 were included. The data of laboratory test, diagnosis, and treatment were analyzed. The main outcomes included the incidence of hyperkalemia, the diagnosis rate, the treatment rate, treatment pattern and the 7-day retesting rate.Results:A total of 1 039 245 patients who met the above criteria were included, of whom, 36 615 (3.52%) had at least one hyperkalemia event. Among the emergency patients with chronic kidney disease, heart failure, diabetes mellitus and hypertension, the proportions of patients who experienced hyperkalemia were 47.69%, 29.13%, 21.69% and 10.16%, respectively. The diagnosis rate of emergency hyperkalemia patients was 9.23%. The overall hyperkalemia treatment rate was 42.1%. Insulin + glucose injection was the most commonly used therapy for emergency hyperkalemia patients. The overall serum potassium retesting rate within 7 days was 28.8%.Conclusions:Hyperkaliemia is more common and more severe in patients with chronic kidney disease, heart failure, diabetes and hypertension. The diagnosis rate and retesting rate of hyperkalemia are low, suggesting that the identification and management of hyperkaliemia in emergency patients should be strengthened.

The role of glial scar after intracerebral hemorrhage(ICH)remains unclear.This study aimed to inves-tigate whether microglia-astrocyte interaction affects glial scar formation and explore the specific function of glial scar.We used a pharmacologic approach to induce microglial depletion during different ICH stages and examine how ablating microglia affects astrocytic scar formation.Spatial transcriptomics(ST)analysis was performed to explore the potential ligand-receptor pair in the modulation of microglia-astrocyte interaction and to verify the functional changes of astrocytic scars at different periods.During the early stage,sustained microglial depletion induced disorganized astrocytic scar,enhanced neutrophil infiltration,and impaired tissue repair.ST analysis indicated that microglia-derived insulin like growth factor 1(IGF1)modulated astrocytic scar formation via mechanistic target of rapamycin(mTOR)signaling activation.Moreover,repopulating microglia(RM)more strongly activated mTOR signaling,facilitating a more protective scar formation.The combination of IGF1 and osteopontin(OPN)was necessary and sufficient for RM function,rather than IGF1 or OPN alone.At the chronic stage of ICH,the overall net effect of astrocytic scar changed from protective to destructive and delayed microglial depletion could partly reverse this.The vital insight gleaned from our data is that sustained microglial depletion may not be a reasonable treatment strategy for early-stage ICH.Inversely,early-stage IGF1/OPN treatment combined with late-stage PLX3397 treatment is a promising therapeutic strategy.This prompts us to consider the complex temporal dynamics and overall net effect of microglia and astrocytes,and develop elaborate treatment strategies at precise time points after ICH.
