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.

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.

Objective:To compare the outcomes of arthroscopic rotator cuff repair in patients with or without stiffness.Methods:Retrospective analysis was performed on the data of 20 patients (stiffness group) who underwent arthroscopic rotator cuff repair combined with capsular release from January 2017 to November 2019. There are 9 males and 11 females, age 62.2±8.7 years old (range 45 to 80 years old), preoperative duration 5.2±4.3 months (range 1 to 12 months). 54 patients who underwent arthroscopic rotator cuff repair without stiffness were used as the control group. There were 16 males and 38 females, aged 60.9±9.1 years old (range 46 to 81 years old), preoperative duration 8.2±13.0 months (range 1 to 60 months). Pain, function and range of motion (ROM) were recorded at 1 month, 3 months, 6 months post-operatively and last follow-up, and compared with that of pre-operatively. Satisfaction and complication were recorded at the last follow-up. The main outcome measurements included the visual analogue scale (VAS), the American Shoulder and Elbow Surgeons (ASES) score, the University of California at Los Angeles shoulder rating scale (UCLA), Constant-Murley score, and range of motion.Results:The mean follow-up period was 19.7±4.6 months (12-30 months) in the stiffness group, and 18.6±4.4 months (12-29 months) in non-stiffness group. VAS, ASES score, UCLA score, Constant-Murley score and ROM were significantly improved post-operatively. One month post-operatively, the VAS score was 4.2±1.5 in stiffness group, and 3.4±1.1 in the non-stiff group, and the difference was statistically significant between two groups ( t=2.381, P=0.020). There was no significant difference at 3 months post-operatively. The ASES score, UCLA score and Constant-Murley score were 52.3±10.2, 17.8±4.2 and 51.7±9.7 in stiffness group at 3 months post-operatively, and 57.4±7.4, 21.6±3.8, 63.2±13.5 in non-stiffness group, respectively. The difference was statistically significant ( t=2.363, P=0.021; t=3.713, P<0.001; t=3.484, P<0.001). There was no significant difference at 6 months post-operatively. The postoperative satisfaction of stiffness group and the non-stiffness group were 95.0% and 96.3%, respectively. The difference was not statistically significant ( χ2=0.2511, P=0.802). Conclusion:The results of stiffness group are statistically the same as those in non-stiffness group at last follow-up, although the recovery period is longer in patients who combined with stiffness at the first 6 months.

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 .

AIM: To investigate the functional role of TGF-?_1 signal protein Smad2/3 in tubulointerstitial fibrosis associated with unilateral ureteral obstruction in rats. METHODS: The unilateral ureteral obstruction (UUO) model was induced by the ligation of left ureter. Rats were sacrificed at 1, 3, 7, 14, 21, and 28 days after UUO was initiated. TGF?_1 protein, phosphorylated Smad2/3 and interstitial ?-smooth muscle actin (?-SMA) expression were assayed by immunohistochemical staining. TGF-?_1 mRNA in the obstructed kidney was analyzed with in situ hybridration. HE and Masson staining were used for histological and morphometric studies of the pathological change in obstructed kidney. RESULTS: The results showed that upregulation of TGF-?_1 in tubulointerstitium of both cortex and medulla at day 3 (a 3.1 fold increase vs control, P

AIM:To investigate the expression and probable role of extracellular signal-regulated protein kinase(ERK1/2)in renal fibrosis associated with diabetic in mice.METHODS:Male homozygous C57BL/6 mice were divided at random into control group(intraperitoneally injected with citrate buffer)and diabetes group(received 5 consecutive daily intraperitoneal injections of streptozotocin at dose of 50 mg?kg-1?d-1).All mice were followed up for 16 weeks.Diabetes was confirmed by serum glucose levels exceeding 16.7 mmol/L.Mice were killed at 0,4,8,12 and 16 weeks respectively after streptozotocin injection.The kidney tissues were obtained from diabetic and control mice.Serum glucose,kidney weight/body weight(KW/BW),24 h albumin excretion rate(UAE)and the serum creatinine(Scr)were measured.The kidney tissue was used for histological and morphometric studies of glomerular size,glomerular matrix expansion(PAS),and the expression of TGF-?1,phosphorylated ERK1/2 and collagen Ⅲ by immunohistochemical staining.RESULTS:The serum level of glucose in streptozotocin-induced diabetic mice increased significantly.The kidney weight/body weight ratio,glomerular volume and glomerular matrix expansion in diabetic mice were obviously higher than those in control mice.Serum creatinine and 24 h albumin excretion rate in diabetic mice increased significantly compared with control mice.TGF-?1,phosphorylated ERK1/2 and collagen Ⅲ levels were obviously increased in the kidney of diabetic mice compared with those in control mice(P
