Objective To investigate the correlation between Toll-like receptor2 (TLR2) gene promoter region -597T/C polymorphism and primary ANCA associated small vasculitis (AAV) in Guangxi Han people. Methods A case contrastive control study was adopted in the study. Patients with AAV (patients group, n=110) and healthy people (control group, n = 200) were recruited. Associated serum indexes were detected and polymorphisms of TLR2 gene promoter 597T/C were analyzed by polymerase chain restricted fragment length polymorphisms (PCR-RFLP). Results (1)Three TLR2-597T/C genotypes were discovered in 110 AAV patients, namely, TT, TC and CC, with the frequency of 54.55%,40.00% and 5.45% respectively. And the frequencies of allele T and C were 74.55% and 25.45%. In control group, the genotype frequencies of TT, TC and CC were 56.00%,40.50% and 3.50%, with 76.25% of allele T and 23.75% of allele C. No significant differences were found in neither genotype distribution nor allele frequencies between the patients group and control group ( P > 0 . 05 ) . ( 2 ) Significant differences were found in the incidence of proteinuria rate and the hemoglobin (P< 0.05)in AAV patients. (3)There was no significant difference between AI and CI in TT, TC and CC genotype in AAV patients. Conclusions Polymorphism of TLR2-597T/C may be correlated with the incidence of proteinuria and the level of hemoglobin, while no obvious correlation with the genetic susceptibility of ANCA in vasculitis patients of Guangxi Han people.

Objective To investigate the association between TGFβ1-509 C/T gene polymorphism with primary ANCA associated vasculitis (AAV) in Chinese Han population . Methods The blood DNA and clinical data of 88 patients were collected, TGFβ1-509 C/T genotypes were determined by PCR-RFLP, 107 healthy individuals were tested as controL Clinical and pathological data of the patients with different genotype were compared. Results No significant difference was found in neither genotype distributions nor allele frequencies between the patients and the control (P > 0. 05). Significant difference was found in uria protien level of the three groups of patients with different genotypes(P <0.05) ,but not in blood pressure, serum urea nitrogen or creatinine, vasculitic damage index, birminghan vasculitis activity score (P > 0. 05 ). Significant difference was found in med-heavier glomerular mesangial proliferation of the three groups ( P < 0.05 ) , but not in lighter glomerular mesangial proliferation, glomerular sclerosis, crescent formation and tubule-interstitial fibrosis and atrophy. Conclusions In Chinese Han population, TGFβ1-509 C/T polymorphism might have no relationship to susceptibility of primary AAV, but might relate to uria protein and med-heavier degree of mesenterium proliferation.

OBJECTIVETo investigate the impact of in utero exposure to di-n-butyl phthalate (DBP) on the apoptosis of testicular cells in the pubertal male rat offspring.
METHODSTen pregnant SD rats were randomly divided into a control and an experimental group to be treated intragastrically with olive oil (1 ml per day) and DBP (500 mg per kg of body weight per day) respectively between gestation days 12 and 19. At the pubertal age (postnatal day 45, PND 45), the testes of the male rat offspring were removed for observation of the cell structure under the transmission electron microscope and the development of different spermatogenetic cells by HE staining. The apoptosis of testicular cells was detected by the TUNEL method, the expressions of the apoptosis-regulating proteins Bcl-2, Bcl-XL, Bax and p53 were determined by immunohistochemistry and Western blot, and the data obtained were compared between the two groups by t-test.
RESULTSTransmission electron microscopy revealed increased apoptosis and vacuolization of testicular cells in the PND-45 rat offspring, HE staining showed markedly decreased numbers of different spermatogenetic cells, TUNEL manifested significantly increased apoptosis of testicular cells in the experimental group as compared with the control (12.00 ± 5. 22 vs 3.17 ± 1.47, P < 0.01), and immunohistochemistry and Western blot exhibited remarkably higher expressions of Bax and p53 in the former than in the latter group (P < 0.05).
CONCLUSIONIn utero exposure to DBP can increase the apoptosis of germ cells and Sertoli cells, induce the vacuolization of testicular cells, and significantly elevate the expressions of the apoptosis-promoting proteins Bax and p53 in the pubertal male rat offspring.

Objective To investigate the role of transcriptional-coactivator with PDZ-binding motif( TAZ) in genistein-induced osteoblastogenic differentiation of mouse bone marrow-derived mesenchymal stem cells ( BMSCs) .Methods Mouse BMSCs were cultured in phenol red-freeα-MEM containing osteogenic supplements for inducing osteogenic differentiation.BMSCs were transfected with siRNA-TAZ and treated with genistein.The temporal sequence of osteoblastic differentiation in BMSCs cultures was assayed by measuring alkaline phosphatase activity (ALP) and calcium deposition.The mRNA expression of bone sialoprotein ( BSP) and osteocalcin ( OC) were detected by reverse transcription-polymerase chain reaction(RT-PCR).The binding interaction between TAZ and cbfa1 was identified by co-immunoprecipitation.Results TAZ expression was detected during the induction of osteogenic differentiation, the ALP activity and calcium deposition were significantly decreased in BMSCs which were transfected with siRNA-TAZ.Genistein(0.01-1 μmol/L) exhibited a dose-dependent effect on TAZ expression in mouse BMSCs cultures.Treatment with genistein ( 1 μmol/L ) resulted in increased ALP avtivity and calcium deposition of BMSC cultures as function of time.Genistein(1μmol/L) also promoted the nuclear localization of TAZ and augmented the interaction between TAZ and cbfa1, and by which upregulated cbfa1-mediated gene expression such as BSP and OC.However, the ALP avtivity and calcium deposition, as well as the expression of BSP and OC were not promoted by genistein in BMSCs transfected with siRNA-TAZ.Conclusion These data suggest that the TAZ plays an important role in genistein-induced osteoblastic differentiation of mouse BMSCs cultures.

Objective To investigate the relationship between putative rs5744168 of Toll-like receptors 5 (TLR5)and ANCA associated small vasculitis (AAV) in Guangxi Han nationality. Methods Polymorphism was analyzed by polymerase chain restricted fragments length polymorphism in 120 cases with AAV and 212 controls. Results (1)There were two genotypes of CC and CT in AAV group and control group. The frequencies distribution of CC and CT in 120 AAV patients were 82.50% and 17.50% respectively and the frequencies of allele C and T 91.25% and 8.75%,respectively. In controls,the genotypefrequencies of CC and CT were 88.68% and 11.3%, and frequencies of allele C and T 94.34% and 5.66%, respectively. No significant difference was found in either genotype distribution or allele frequencies between the patients and the controls ( P > 0 . 05 ) . ( 2 ) Significant reductions in the incidence of BUN, uric acid, quantitative test of 24 h urinary protein and erythrocyte sedimentation rate(ESR) were found in CC genotype (P < 0.05). (3) Binary regression model with a logit link function found total cholesterol was related with AAV. Conclusion The susceptibility of AAV in Guangxi Han population has nothing to do with the polymorphism of rs5744168.In AAV patients, polymorphism of rs5744168 may be associated with ESR, BUN, uric acid and quantitative test of 24 h urinary protein levels.

Objective To investigate the relationship between TGFβ1-509 C/T, TCRCα-575 A/G SNPs and primary AAV using a transmission disequilibrium theory based pedigree analysis Methods Genotypes of 264 individuals from 88 AAV families include patients, their parents, brothers and sisters were determined by PCR-RFLP and direct sequencing. Transmission disequilibrium test(TDT) and HRR were employed for the data analysis to observe the transmission disequilibrium of TGF31-509 C/T and TCRCα -575 A/G polymorphisms. Results No transmission disequilibrium from heterozygous parents onto the patients was found in the trios analyzed by TDT for either TGFβ1-509 C/T (observed C/T = 36/28, expected C/T =33. 5/30. 5, x2 =0.51, P>0.05) or TCRCo-575 A/G ( observed A/G = 29/39, expected A/G = 33.5/34. 5, x2 = 1. 59, P > 0. 05 ). The genotype-based HRR and haplotype-based HRR showed there was no increased risk of AAV in the observed trios for either -509 C/T polymorphism of TGFβ1 (transmitted genotype CC/CT/TT =12/20/6, allele C/T = 44/32; nontransmitted genotype CC/CT/TT = 10/19/9,allele C/T =39/37, genotype-based HRR x2 =0.81, P >0. 05, haplotype-based HRR x2 =0. 66, P>0. 05,HRR = 1.30) or -575 A/G polymorphism of TCRCα ( transmitted genotype AA/AG/GG = 9/18/12, allel A/G = 36/42; nontransmitted genotype AA/AG/GG = 15/15/9, allel A/G = 35/33, genotype-based HRR x2=2. 20, P >0. 05. Haplotype-based HRR x2 =0. 41, P >0. 05, HRR =0. 81 ). The deviation of HRR coefficient was not excessive(1.00). Conclusion TGFβ1-509 C/T and TCRCo-575 A/G polymorphism may not be associated with the genetic susceptibility of primary AAV in Guangxi Han population.
