Objective To explore the changes of serum gastrin(GAS),plasma motilin(MTL) and somatostatin(SST) in critically ill children with gastrointestinal dysfunction(GID).Methods According to pediatric critical illness score,75 cases were divided into greatly critical group(score90).Fifty cases of greatly critical and critical group were divided into GID group and non-GID group.The levels of serum GAS,plasma MTL and SST were detected on an empty stomach at acute stage and convalescence stage,comparing with those of normal control group,and then,the relationship between the levels of serum GAS,plasma MTL,SST and GID,the severity of disease were analyzed.Results At acute stage,the levels of serum GAS and plasma MTL of greatly critical group and critical group were higher than those of normal control group,the levels of plasma SST of greatly critical group and critical group were lower than that of normal control group,the more severe condition of critical children,the higher level of serum GAS and plasma MTL,the lower level of plasma SST.At convalescence stage,the level of serum GAS and plasma MTL of the greatly critical group and critical group decreased and the level of plasma SST increased.The levels of serum GAS and plasma MTL of GID group were higher than those of non-GID group,but the level of plasma SST of GID group was lower than that of non-GID group.Conclusion The level of serum GAS,plasma MTL and SST can be used to assess the severity of illness and prognosis,judge the change of disease and determine the efficacy of treatment programs,and detect gastrointestinal functional lesion.

OBJECTIVETo investigate ORMDL3 polymorphisms in children with asthma in Hunan, China, and to determine the relationship between ORMDL3 polymorphisms and serum osteopontin (OPN) and transforming growth factor-β1 (TGF-β1) levels.
METHODSPeripheral blood samples were collected in children with asthma (n=98; astma group) or without asthma (n=30; control group) from Hunan, China. The asthma group was subdivided into atopic (n=62) and non-atopic (n=36) subgroups. Single nucleotide polymorphism (SNP) analysis was performed, and serum OPN and TGF-β1 levels were measured.
RESULTSThere were no significant differences in genotype and allele frequencies of rs7216389 of the ORMDL3 gene between the asthma and control groups. The serum level of OPN in the asthma group was significantly higher than in the control group (P<0.05). Both the atopic and non-atopic subgroups showed increased serum levels of OPN compared with the control group (P<0.05). The serum level of TGF-β1 in the atopic subgroup was significantly higher than in the control group (P<0.05). The serum levels of OPN and TGF-β1 showed no significant differences in asthmatic children with different genotypes. The serum levels of OPN and TGF-β1 were in a positive linear correlation in the asthma group (r=0.620; P<0.01) and its two subgroups (r=0.734, 0.649 respectively; P<0.01).
CONCLUSIONSIn children from Hunan, China, the SNP (rs7216389) of ORMDL3 is not related to asthma susceptibility. OPN and TGF-β1 may be involved in the development of asthma, and they are in a positive linear correlation. The SNP (rs7216389) of ORMDL3 does not influence the expression of OPN and TGF-β1, suggesting that it may not be associated with airway remodeling.

ObjectiveTo explore the expression of CD3+ CD8+ human leukocyte antigen (HLA)-A2+T lymphocytes with specificity to the different hepatitis B virus (HBV) peptides in the peripheral blood mononuclear cells (PBMC)from the patients with hepatitis B associated hepatocellular carcinoma (HCC).MethodsThe HLA-A2+ PBMC from four patients with hepatitis B associated HCC were incubated with five HBV/HLA-A2 pentamers respectively,which were HBV sAg (FLLTRILTI),HBV sAg (GLSPTVWLSV),HBV sAg (WLSLLVPFV),HBV core (FLPSDFFPSV),and HBV pol (FLLSLGIHL),as well as anti-CD3-pacific blue and anti-CD8-fluorescein isothiocyanate (FITC).Then,HBV/HLA-A2-CD3-CD8 positive cells were detected by flow cytometry. The monoclonal HBV/HLA-A2-CD3-CD8+ cells were acquired by fluorescenceactivated cell sorter,and cultured and identified by flow cytometry.The anti-HBV specific T lymphocytes were then cultured with HepG2 (HLA-A2+ ) cells and the release of interferon γ (IFN-γ)were determined by enzyme-linked immunosorbent assay (ELISA),Res(a)ltsThe percentage of antiHBV T lymphoeytes with specificity to GLSPTVWLSV in total CD8+ T lymphoeytes from four patients with hepatitis B associated HCC was 1.44%±0.04%,which was higher than those to other four HBV antigen peptides (0.68%±0.08% of FLLTRILTI,1.06%±0.09% of FLPSDFFPSV,0.56% ±0.04% of FLLSLGIHL,and 0.46% ±0.08% of WLSLLVPFV) (t=0.001,P<0.05).The two lines of monoclonal cell with specificity to GLSPTVWLSV both exhibited high level of IFN-γ expression after incubated with hepatic carcinoma cell line HepG2 (HLA-A2+)with HBV GLSPTVWLSV peptide.ConclusionsCD3+ CD8+ HLA-A2+ cells with specificity to the different HBV peptides exist in PBMC of patients with hepatitis B associated HCC.The expression level depends on HBV antigen peptide sequences and genomic sites.

Objective To find out the best method for elimination of uranium contamination in rat tissues as low as possible by removal of shrapnel fragments. Methods Experimental rats were divided into six groups: route group, decontamination before surgery group, decontamination in incision group, changing surgical appliances group, removing tissues around group, and comprehensive method group. Uranium concentrations in tissues and fluids in all groups were measured at 7, 14, and 21 d after operation. The efficiency of decontamination by different methods was compared. Results The highest uranium concentration in tissues was found in the route group, but the lowest in the comprehensive method group, and the second lowest in removing tissues around group. Conclusion The comprehensive method is the best one in all of the surgical removal methods. The soft tissues around DU shrapnels should be removed if they are not critical organs.

OBJECTIVETo screen the differentially expressed proteins in the urine of children with steroid-sensitive and steroid-resistant minimal change nephrotic syndrome (SRINS and SSINS, respectively).
METHODSUrine samples were collected from 10 children with SRINS and 70 with SSINS as well as 30 healthy volunteers (control). Isoelectric focusing and two-dimensional electrophoresis in combination with matrix assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometry was performed for analysis of the urine proteins.
RESULTS AND CONCLUSIONIn the urine samples, 30 protein spots were identified to have differential expression between SRINS and SSINS. Further analysis of 14 protein spots identified 12 proteins expressing in SRINS, namely kinesin family member 27, PITPNB, bullous pemphigoid antigen, alpha-1 protease inhibitor, Zn-alpha-2GP, alpha-1B-glycoprotein, serum albumin precursor, haptoglobin precursor, kinesin like motor protein, IRAK4, cytoplasmic dynein and cytokeratin 9. Nine of these 12 proteins were up-regulated (U1-U3, U5, U7-U9, U11-U12) and 3 down-regulated (D4, D6, D10) in SRINS, suggesting that these proteins may serve as the potential therapeutic targets and as new diagnostic markers for steroid-resistant nephrotic syndrome.
