Post-cardiac arrest syndrome (PCAS) is one of the most common medical emergencies in children.The fatality rate and disability rate are extremely high.Pathogenesis of PCAS remains incompletely clear,and clinical manifestation is complicated.The treatment is mainly limited to supportive care.In recent years,the phases of PCAS are defined according to the pathophysiological changes and clinical prognosis.Investigators also made some advances in the fields of pathophysiological changes and clinical treatment of brain damage and myocardial damage.For the treatment of PCAS,early therapeutic hypothermia,glucose control and seizure control,and reasonable cardiopulmonary support are promoted.In this article,we reviewed the advances in the above fields and the latest advance on the management of PCAS in foreign countries.

Objective To evaluate the application of early 18F-FDG PET-CT imaging after radiofrequency ablation (RFA) of hepatic malignancies. Methods Fifteen patients with liver tumors (five hepatocellular carcinoma, ten colorectal cancer liver metastasis ) underwent RFA as part of clinical management. The lesions were all hypermetabolic on PET-CT performed within 2 weeks prior to RFA. All subjects underwent 18F-FDG PET-CT (early PET-CT) within 24 hours after RFA. Total photopenia, focal uptake, and rim-shaped uptake were regarded as complete ablation, residual tumor, and inflammation, respectively. Follow-up PET-CT scans were performed as the reference standard. Results Twelve patients showed total photopenia at the ablation site on the early PET-CT scan, and in all of these patients, total photopenia at the ablation sites was seen on the follow-up PET-CT scans. Two patients had focal uptake at the ablation sites on the early PET-CT scan, and both of these foci increased in size and intensity, which were compatible with residual tumors at the time of ablation. Only one patient had rim-shaped uptake on the early PET-CT scan. The rim-shaped uptake disappeared on PET-CT performed 3 months later, which indicated the nature of inflammation. Conclusions There is infrequent inflammatory uptake at the RFA site of liver tumors on 18F-FDG PET-CT if scanning is performed within 24 hours after ablation. Thus, early PET-CT has the potential to evaluate the efficacy of an RFA procedure by indicating tumor-free as total photopenia and residual tumors as focal uptake.

Objective To analyze the influence of age on the diagnosis of acute heart failure (AHF) with amino terminal brain natriuretic peptide (NT‐proBNP) ,and to explore the best cut‐off value of NT‐proBNP in the diagnosis of AHF .Methods Totally 457 inpatients suspected with AHF obtained a blood NT‐proBNP measurement within 24 hours when in charged ,including 194 patients with AHF .Patients were divided into three groups according to their age :≤50 years ,>50-70 years and >70 years . The relationship between NT‐proBNPand AHF was analyzed .The diagnostic value of NT‐proBNP was evaluated for AHF in differ‐ent age groups .Results The median NT‐proBNP levels of AHF in all age groups were significantly higher than those without (P<0 .01) .AUC of NT‐proBNP for AHF in ≤50 years ,>50-70 years and >70 years groups were 0 .95 ,0 .91 ,0 .88 ,the best diagnos‐tic cut‐off points were 1 100 ,1 800 ,3 000 pg/mL ,respectively .The diagnostic specificity was 88% ,76% and 73% ,respectively .O‐verall ,the specificity of NT‐proBNP cut‐off values for age group was higher than non‐age groups .Conclusion NT‐proBNP has a good value in the diagnosis of AHF in patients with different ages .According to the age group ,the different NT‐proBNP cut‐off values can be used to improve the specificity of diagnosis .

Objective To investigate the effect of hepatopoietin Cn(HPPCn) on liver stem cells.Methods In this study, WB-F344 cell line was used, and MTT and flow cytometry assay were conducted to determine cell proliferation and apoptosis.Transwell assay was used to test the migration of WB-F344 cells.A 2AAF-partial hepatectomy(PH) mouse model was used to observe the effect of HPPCn on liver stem cell proliferation in vivo.Results HPPCn enhanced WB-F344 cell proliferation and migration and activated the SphK1, Erk and Stat3 signal pathways.The analysis of the 2AAF-PH mouse model showed that oval cells in the experimental group far outnumbered those in control and the regeneration of the liver was improved post PH.Conclusion HPPCn can increase the liver stem cell proliferation and survival while promoting the regenenation of the liver by augmenting oval cell proliferation.

Encephalomyocarditis virus (EMCV) ,named JZ1202 ,was isolated from domesticated boar in Henan ,China . We performed the full-length genome sequencing and molecular characteristic analysis of the isolated strain .Results showed that the full-genome sequence of EMCV JZ1202 generated a sequence of 7 735 bp in length ,and had 81 .2%-99 .9% nucleotide identity with other reference strains from different animals ,but 99 .4% with Chinese reference from pig .The phylogenetic tree was constructed based on the full-length genome;ORF and VP1 gene sequences identified EMCV was divided into G1 ,G2 and G3 groups ;the strain JZ1202 belongs to G1 with other Chinese reference strains .Results identified that the EMCV infection could cause severe clinical symptoms in domesticated boar .Big regional differences exist in EMCV and the transmission is limit-ed in a range of area .However ,cross infection and prevalence of EMCV disease between domesticated boar and mice might ex-ist .Mutation of some amino acid may occurred in EMCV infected domesticated boar .

In subclinical diabetic nephropathy with glomerular hyperfiltration,the renal size parameters are increased significantly,and this change sets in as early as before the appearance of microalbuminuria.The average kidney length discriminator value for glomerular hyperfiltration by receiver operating characteristic (ROC) curve analysis is 10.53 cm,with the best sensitivity,higher specificity and total coincidence rate,and can be a clinical indicator for screening early diabetic nephropathy with glomerular hyperfiltration.
