Aim To investigate the effect of curcumin on the expressions of NR2A, NR2B and apoptotic neurons in hippocampus after global brain ischemia-reperfusion in SD rats. Methods Global ischemic model induced by 4-vessel occlusion was adopted. Rats were randomly divided into 5 groups: sham group (SH), ischemia-reperfusion group (I/R), curcumin 30(Cur 30), 100 (Cur 100) and 300 mg?kg-1 group (Cur 300). At different time points after ischemia, animals were designated as subgroups 2 h, 6 h, 1 d, 3 d, 7 d. Cell morphology was observed on HE stain slides. The apoptotic neurons were detected in CA1 region by TUNEL method. Expressions of NR2A and NR2B in hippocampal CA1 and CA3/DG regions were detected by Immunohistochemical technique. Results At each time point the number of apoptotic neurons was much more in I/R group than that in SH group and Cur 100 group,and in Cur 300 group than that in Cur 100 group. The expression of NR2A was higher in the hippocampal CA1 and CA3/DG regions in Cur 100,Cur 300, Cur 30 and SH groups than that in I/R group at each time point(P

Objective To explore the correlation between-173G/C gene polymorphism of macrophage migration inhibitory factor(MIF) and Henoch-Schonlein purpura(HSP),Henoch-Schonlein purpura nephritis(HSPN) in children in Jiangxi Province.Methods One hundred and thirty-one ethnic Han children with HSP were enrolled,including 80 children with concurrent nephritis(HSPN group) and 51 children without nephritis(HSP without nephritis group).One hundred and five healthy children were used as the healthy control group.Germline DNA was extracted from peripheral blood by Promega blood genomic DNA kit.Polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) was used for genotyping the-173G/C polymorphism of MIF.Genotype distribution and allele frequencies were obtained by direct counting.Statistical analysis was performed by using SPSS 11.5 software.Allele and genotype distribution were compared by using the chi-square test.The relative risk of allele was described by odds ratios(OR) and 95% confidence intervals(95%CI).Results Three genotypes(GG,GC,CC) were detected in MIF-173 G/C.GG,GC genotypes were detected in HSP without nephritis and healthy control group.GG,GC and CC genotypes were detected in HSPN group.Mutant genotype(37.5%) and C allele frequency(20.0%) in HSPN group were significantly higher than those in healthy control group(20.0% and 10.0%,respectively)(?2=6.964,7.400,Pa

ObjectiveTo explore the correlation between IL-6-634C/G gene promoter polymorphism and body mass index (BMI),blood sugar (BS),25-hydroxy vitamin D (25-OH-D),and serum lipid levels by investigating in 8-12-year-old Han children in Shanxi province,China.MethodsIn Datong city of Shanxi province,214 8-12-year-old children were enrolled after obtaining informed consent from their parents.The weight and height were measured and the BMI was calculated.BS,serum lipids,and 25-OH-D were determined.IL-6-634C/G polymorphism were detected by polymerase chain reaction restricted fragment length polymorphism.The effects of genotype on BMI,BS,serum lipids,and 25-OH-D were also studied.ResultsThe genotypes of IL-6-634C/G polymorphism in 214 cases were GG ( 15％ ),GC (40％),and CC (45％).The percentages of C and G allele frequencies were 65％ and35％.The genotypes and allele frequencies showed no gender differences ( P ＞ 0.05 ).However,significantly different GG genotypes frequencies were found between overweight and obese children (38.3％) and other children ( normal weight children: 7.3％ ; thin children: 10.9％ ) (x2 =14.715,P =0.006).Multivariate logistic regression analysis showed that IL-6-634C/G polymorphisms and triglyceride were correlated with overweight and obesity (P ＜ 0.05 ).25-OH-D was not correlated with BMI (r =0.075,P =0.528),BS ( r =0.018,P =0.880 ),triglyceride ( r =- 0.097,P =0.417 ),high density lipoprotein cholesterin ( r =0.038,P =0.751 ),and low density lipoprotein cholesterin ( r =- 0.028,P =0.817 ).25-OH-D was not significantly different between overweight and obesity children.The distribution of three genotypes showed no correlation with 25-OH-D deficiency (x2 =0.622,P =0.733 ).ConclusionsIL-6-634C/G polymorphism exists in Han children in Shanxi province.IL-6 gene 634 GG genetype is a risk factor of childhood overweight and obesity,and may affect lipid metabolism.However,it has no direct impact on glucose metabolism.IL-6 gene 634C/G polymorphism and serum 25-OH-D are not relevant.IL-6 gene 634C/G polymorphism is not related to vitamin D deficiency diseases,and may be not related to bone calcium metabolism.25-OH-D is not relevant with BS and blood lipids level,and also is not associated with childhood overweight and obesity.

Objective To explore the clinical application of extracorporeal membrane oxygenation (ECMO) assisted cardiopulmonary resuscitation (CPR)in the treatment of critically ill children with cardiac arrest.Methods The clinical data of critically ill children due to cardiac arrest who were treated with ECMO assisted CPR from June 2012 to December 2015 in Affiliated Bayi Children's Hospital,Clinical Medical College in Army General Hospital,Southern Medical University were retrospectively reviewed,and the datas were analyzed by SPSS 20.0 software.Results A total of 17 patients received ECMO assisted CPR treatment,13 cases were male,4 cases were female,aged from 5 hours to 5 years old,the weight ranged from 3 to 16 kg;5 cases survived,and the survival rate 29.41％;12 cases died,the mortality rate 70.59％,of which 5 cases died of hear failure in withdrawal of ECMO,and 7 cases died of complications after withdrawal of ECMO.The age,sex ratio,body weight and other demographic data between 2 groups were not statistically significant (all P ＞ 0.05).There was no significant difference in the primary diseases between 2 groups (P ＞ 0.05).There was no significant difference in CPR time and ECMO support time between 2 groups (t =1.541,0.375,all P ＞ 0.05).Among 11 cases of children with ECMO-related complications,the incidence rate was 64.71％,the incidence of complication in the survival group was significantly less than that in the death group (x2 =8.709,P =0.003).The common complications of ECMO were bleeding,acral necrosis,infection,multiple organ failure,nervous system injury and acute kidney injury.There was no significant difference in the level of lactic acid between the survival group and the death group (P ＞ 0.05) before ECMO support started,but after 24 h of ECMO support,the lactic acid level in the survival group was significantly lower than that in the death group (t =2.896,P =0.014).Conclusions ECMO assisted CPR can improve the survival rate of critically ill children who have cardiac arrest and have no response to the conventional CPR.The serum lactic acid level after 24 h ECMO support has a guiding significance for the prognosis assessment,and ECMO patients' complications are still the most important factor affecting the prognosis of ECMO assisted CPR patients.

Objective:To design an intra-abdominal pressure measuring device applied to children on peritoneal dialysis (PD), and evaluate the feasibility and safety of the application of the device.Methods:The device consisted of a three-way stopcock with extension tubing, a three-way stopcock, a manometer tube, and a "Y" system peritoneal dialysis bag. The intraperitoneal pressure of different fill volumes was measured when a child was supine and relaxed in a horizontal position. The subjects of the study were children who received PD at the Pediatric Hospital of Fudan University from May 2019 to February 2020 and had PD dialysis age of>1 month. The children's demographic and clinical information were collected. During the measurement, the child’s complaints of pain, bloating, vital signs, and catheter-related contamination were recorded. Additionally, the occurrence of dialysis-related infections and complications during the hospitalization and outcomes of PD after three months of the measurement were tracked. A scatter plot and Pearson correlation test were used to explore the correlation between fill volumes and the intraperitoneal pressure.Results:Nine PD children were included in our study. The age of the children was (8.4±4.7) years old. The body surface area is (0.84±0.29) m 2. The intraperitoneal pressure was (12.6±1.9) cmH 2O at the fill volume of 1 000 ml/m 2 and (13.8±1.9) cmH 2O at the fill volume of 1 200 ml/m 2. The measurement was smoothly and safely taken without any case of contamination and dialysis-related infections during the hospitalization. After three months of the measurement, one child was transferred to temporary hemodialysis due to the aggravation of the umbilical hernia. Conclusions:The intraperitoneal pressure measuring device is feasible and safe to perform among children with PD. It can achieve non-invasive and continuous measurement of intra-abdominal pressure, and has guiding significance for the dialysis prescription of children with PD.
