Objective To explore the association of Toll-like receptor 4 TLR4 and lipopolysaccharide receptor CD14 gene polymorphisms with Kawasaki disease (KD) susceptibility.Methods Three-color fluorescent staining flow-cytometry was used to detect the expression of TLR4 in peripheral blood white blood cell of 76 KD children and 118 healthy control group.The gene of TLR4 (-896A/G), (-1196C/T) and CD14 (-260C/T) polymorphisms was identified by polymerase chain reaction-restriction fragment length polymorphisms; and the relationship between genotype and KD was analyzed.Results 1.The values of mean fluorescence intensity (MFI) of TLR4 in peripheral blood white blood cell of the KD groups and the healthy control groups were 2.87?0.96, 10.55?4.87, 23.36?8.28 and 3.26?0.65, 7.55?1.21, 25.41?6.97, respectively; There was a gradual increase of these values on lymphocyte, neutrophilic leukocyte and mononuclear cell in both groups.2.(-896A/G), (-1196C/T) polymorphisms of TLR4 gene were not found in both groups.3.The frequency of each genotype of CD14 gene (-260C/T) was 35.5%CC, 30.3%CT, 34.2%TT in KD group and 38.1%CC, 47.5%CT, 14.4%TT in healthy control group.The frequency of each genotype was significantly different in 2 groups(?2=11.62 P

This study aims to investigate the genetic characteristics of hemagglutinin in wild-type measles viruses in Henan Province, China and to provide a basis for measles control and elimination. Specimens were collected from suspected measles cases in Henan during 2008-2012. Cell culture was performed for virus isolation, and RT-PCR was used to amplify hemagglutinin gene. The PCR products were sequenced and analyzed, including construction of phylogenetic tree and analysis of the distance between the isolated virus and the reference virus; then, the variations in predicted amino acids were analyzed. The results showed that 12 measles viruses were isolated in Henan Province and identified as H1a genotype; the nucleotide and amino acid homologies were 98.0%-100% and 97.2%-99.8%, respectively. One glycosylation site changed in all the 12 sequences because of the amino acid mutation from serine to asparagine at the 240th site, as compared with Edmonston-wt. USA/54/A. Overall, the wild-type measles virus genotype circulating in Henan Province from 2008 to 2012 was H1a, with high homology between strains; there were some variations in amino acid sequences, resulting in glycosylation site deletion.

This study was aimed to investigate the distribution and implication of tap1 (transporter associated with antigen processing) and tap2 loci allelic and genotypic frequencies. The distribution of tap1 and tap2 loci allelic and genotypic frequencies in 339 random samples of healthy Chinese Hans was analyzed by TaqMan PCR. Several genetic information about power of discrimination, cumulative DP, polymorphism information content, expected heterozygosity and observed heterozygosity were calculated. The results indicated that 5 tap1 alleles (tap1*0101, 020101, 020102, 0301 and 0401) and 4 tap2 alleles (tap2*0101, 0102, 0103 and 0201) were detected in all samples. 8 tap1 genotypes were found which account for 53.3% of the theoretic genotype and 6 tap2 genotypes were found which account for 60% of the theoretic genotype. The genotyping results of tap1 and tap2 both conform to the Hardy-Weinberg expectations (p > 0.05). Tap1*0101 (79.79%) and tap2*0101 (82.74%) are the most common alleles in Chinese Hans. It is concluded that tap1*0101 and tap2*0101 are most common alleles in Chinese Hans, tap1 and tap2 loci carry some power of individual discrimination and polymorphism information content. These two locl can be used for the research in the fields of human genetics, linkage analysis of genetic disease genes, paternity test and individual identification and so on.

Objective To assess the feasibility of using PET molecular imaging to evaluate the therapeutic effects of traditional Chinese medicine FuZhiSan (FZS) on the model of aging Alzheimer's disease (AD) rats. Methods Twenty aged AD rats (Sparague-Dawley rats,male) were randomly divided into FZS treated group (n = 10) and control group (n = 10). Another 10 healthy adult rats were as blank controls. Morris water maze record system was used for cognitive function assessment. Before and after FZS treatment 18 F-fluorodeoxyglucose (FDG) and 11 C-2- [4'-(methylamino) phenyl] benzothiazol-6-ol ( PIB )PET imaging was undertaken. After post-treatment imaging procedures the brain tissues of all animals were taken for histochemical study,such as staining with HE,congo red,amyloid β (Aβ) immunofluorescence,5-bromo-2-deoxyuridine (BrdU) immunofluorescence and NeuN immunofluorescence. Paired t-test was performed with SPSS 13.0 software for the data analysis. Results The cognitive dysfunction of aging AD rats was improved after FZS treatment. The escape latency in FZS treated group was significantly shorter than that of control group ((32.5 ±10.8) s vs (102.6±8.8) s,t =15.7987,P=0. 0001). Diffuse neuronal loss and Aβ deposition were detected in the hippocampus and cortex in the aged AD rats. The imaging data showed that brain glucose metabolism was amended in FZS treated group while the abatement of amyloid deposition was not significant. Immunofluorescence results indicated that the neuronal proliferation was more remarkable in FZS treated group. Conclusions It may be feasible to use PET imaging as a method to evaluate the therapeutic effect in AD rats. FZS may ameliorate memory dysfunction of aged AD rats. Its mechanism may be partly contributed to the enhancement of the neuronal proliferation and survival.

Human platelet alloantigens (HPA) are specific antigens carried by platelet glycoproteins, which genes showing single nucleotide polymorphism. HPA can induce alloantibodies bringing about alloimmune response. They play important roles in post-transfusion refractoriness to platelets, post-transfusion thrombocytopenic purpura, fetomaternal alloimmune thrombocytopenia, and graft-versus-host disease. Because of their side effects in clinical blood-transfusion, there were a great deal of studies on HPA during last few decades. This review focuses on the nomenclature of HPA, the polymorphisms of platelet glycoproteins, HPA typing of the serological and molecular technology, as well as the mechanism of alloimmunization to HPA and correlated diseases.

OBJECTIVESTo explore the long-term effects,operating opportunity,indication of anterior debridement and decompression and bone graft in treating thoracolumbar tuberculosis with paraplegia.
METHODSFrom March 2006 to September 2008, the data of 56 patients with spinal tuberculosis were retrospectively analyzed. They were 36 cases male and 20 cases female, the age in ranging from 19 to 78 years with the mean of 42.5 years; course of disease in ranging from 3 months to 4 years. The lesion level was in T11-L2, including one stage in 6 cases, two stages in 42 cases, three stages in 7 cases, four stages in 1 case. According to the Frankel grade, grade A in 5 cases, B in 25, C in 21, D in 5. Preoperative Cobb angle had 30 cases under 30 degrees, 24 cases in 30 degrees-60 degrees, 2 cases more than 60 degrees [averaged in (35.0 +/- 3.3) degrees]. The mean VAS was 7.3 +/- 2.1 preoperatively. All patients had chemotherapy for 2-3 weeks. The clinical effects were evaluated by Cobb angle, VAS, condition of Frankel grade and fusion segments.
RESULTSAll patients were followed up from 12 to 38 months with an average of 24 months. All wound obtained primary healing. The Cobb angle was(19.0 +/- 5.5) degrees immediately after operation, and lost (1.8 +/- 0.7) degrees at the follow up. The mean VAS was 1.4 +/- 0.3 postoperatively and 1.3 +/- 0.4 at final follow up. The Cobb angle and VAS significant improved in postoperatively (P < 0.05), and there was no statically difference between after operation and last follow up(P > 0.05). At 1 year after operation, all patients obstained successful bony fusion. Among 51 cases incomplete paraplegia recovered partially or completely (over Frankel D) through chemotherapy and rehabilitation training for 1-1.5 years; 5 cases of complete paraplegia had partially recovered, 3 cases from Frankel A to C, 2 cases from Frankel A to B.
CONCLUSIONBase on the chemotherapeutic effect, paraplegia reason and location, total body condition to select different operative opportunity can effectively relieve spinal compression, stabilize spinal column, correct kyphosis and promote recovery of paraplegia.
