Objecfive To study T cell subsets distribution in peripheral blood from patients with ankylosing spondylitis(AS)and the role of cell immunity in AS.Methods 30 patients with untreated active phase AS and 30 healthy volunteers were enrolled.The expression of CD4+ and CD8+ T cell subsets were evaluated by flow eytome try.The correlation among T cell subsets and Bath AS function index(BASFI).Bath AS measurement index(BASMI),course of disease,age,ESR,hyper-sensitive C-reactive protein (hs-CRP) were analyzed.Results The level of CD4+ T cell and CD4/CD8+ratio were significantly lower than that of healthy volunteers[(29.24±9.22)% vs.(40.09±6.86) %,(0.96±0.49 ) vs.(1.70±0.67 ),P ＜ 0.01 ],and CD8+ T cell were significantly higher than that of healthy volunteers [(32.91±6.86) % vs.(25.60± 5.97 ) %,P ＜ 0.01 ].The level of CD4+ T cell subsets in peripheral blood of AS patients was negatively correlated with BASMI (r =-0.479,P ＜ 0.01 ),and CD8+ T cell subsets were positively correlated with ESR,hs-CRP,BASFI and BASMI ( r = 0.373,0.430,0.462,0.530,P ＜0.05 ).The ratio of CD4+/CD8+ was negatively correlated with hs-CRP,BASFI and BASMI (r = -0.465,- 0.473,- 0.426,P ＜ 0.05 ).CD4+,CD8+,ratio of CD4/CD8 were not significantly correlated with age and course of disease in patients with AS.Conclusion T cell subsets are significantly abnormal in peripheral blood of patients with AS,and the imbalance degree of T cell is correlated with severity and activity of AS,suggesting that T cell subsets imbalance plays an important role in the pathologensis of AS.

Objective To explore the effect of hypoxia on exosomes secreted by renal tubular epithelial cells and the function of exosomes in chronic kidney diseases.Methods (1) The supernatant of renal tubular epithelial cells which were cultured in normoxia (21％ O2) or hypoxia(1％ O2) for 48 h was collected and centrifuged gradiently to harvest exosomes.Exosomes were identified and compared by transmission electron microscope, nanoparticle tracking analysis, Western blotting and measurement of the protein concentration.(2) Primary peritoneal macrophages of rats were co-cultured with exosomes in different concentrations (1, 10, 50, 100, 300 mg/L).The expression of interleukin-6(IL-6), tumor necrosis factor-α (TNF-α), inducible nitric oxide synthase (iNOS) in cells and supernatant were separately detected by quantitative real-time PCR (qRT-PCR) and ELISA, and the expression of phospho (p)-STAT/STAT and suppressors of cytokine signaling 1 (SOCS1) in macrophages was detected by Western blotting.At last, the expression of inflammatory microRNAs (miR) in exosomes was measured by qRT-PCR.Results (1) The vesicles harvested by gradient centrifugation were less than 150 nm and expressed CD63 which was characteristic of exosomes.Hypoxia had no effect on the morphology of exosomes, but stimulated their secretion.(2) Hypoxic exosomes dose-dependently improved the expression of IL-6, TNF-α, iNOS in macrophages polarized by lipopolysaccharide (LPS) and increased the expression of p-STAT while decreased the expression of SOCS1 (P ＜ 0.01).MicroRNAs referred to inflammation such as miR-155 and miR-27a increased in hypoxic exosomes compared to that in normoxic exosomes (P ＜ 0.05).Conclusions Hypoxia makes exosomes promoted the polarization of macrophages to M1, which may account for the microinflammation in chronic kidney diseases.

Objective To explore the detailed underlying molecular and signaling mechanisms in the effects of icariin on bone formation by an in vitro cell model. Methods The proliferation of MC3T3-E1 osteoblast-like cells was evaluated by MTT, and gene expression of cell cycle related proteins in MC3T3-E1 cells after icariin treatment was detected by real-time PCR. The phosphorylation of MAPK signals, including ERK, P38, and JNK was determined by Western blot, and then the inhibitors of MAPK signals were used to treat cells with icariin alone or together to determine the role of MAPKs in the process of icariin treatment on MC3T3-E1 cell proliferation. Alkaline phosphatase and Alizarin red staining were used to detect the formation of mineralization nodules, and gene expressions of alkaline phosphatase, type Ⅰ collagen, and osteocalcin in osteoblasts after being treated by icariin were evaluated by real-time PCR. ICI182780, and nilutamide was used to decide the participation of estrogen and androgen receptor signals in the process of icariin treatment on the differentiation and mineralization of MC3T3-E1 cells. Results Treatment with icariin promoted MC3T3-E1 cell growth in a time- and dose-dependent manner. This treatment also revealed that icariin increased the expression of mRNAs encoding both cyclin E and PCNA, positive regulators of cell growth, but decreased levels of mRNAs encoding Cdkn2b, a negative regulator of cell cycle progression. When MC3T3-E1 cells were cultured in a differentiated condition, icariin enhanced mineralized nodule formation and increased the expression of mRNAs encoding alkaline phosphatase, type Ⅰ collagen, and osteocalcin. Treatment with icariin significantly induced phosphorylation of both ERK and JNK and this phosphorylated effect occurred very rapidly within 5 minutes and reached peak at 15 minutes. Furthermore, the stimulated effects of icariin on proliferation and gene expression of cyclin E, PCNA, and Cdkn2b in MC3T3-E1 cells were dramatically attenuated by treatment with both U0126 and SP600125, inhibitors of MAPKs. Interestingly, such stimulating effects of icariin were at least partly reduced by treatment with ICI182780, an inhibitor of estrogen receptor. Icariin induced mineralized nodule formation and gene expression of alkaline phosphatase, type Ⅰ collagen, and osteocalcin in MC3T3-E1 cells were also partly reduced when the cells were treated with ICI182780. Conclusions Our findings indicate that the anabolic effect of icariin on bone formation is, at least partly, mediated through the MAPK signaling pathway in order to modulate osteoblast proliferation and differentiation.

Objective The study was aimed to detect the correlation of B cell activating factor (BAFF) promotor polymorphism-871 C/T and systemic lupus erythematosus (SLE).Methods BAFF promotor polymorphism-871 C/T was detected by the means of allele specific polymerase chain reaction (ASPCR) and agarose gel electrophoresis in 76 cases of SLE and 80 nonthrombosis normal individuals.The data of genotypic frequency and allele genotypic frequency were analyzed statistically with x2 test between the two groups.Results Fifty-one point two percent of normal individuals exhibited C/C.Thirty-five percent were heterozygous for C/T,and 13.8％ were homozygous for T/T.SLE group exhibited a different distribution pattern (30.3％ C/C,43.4％C/T,26.3％T/T).The allele frequency of T in SLE and normal individuals was 48.0％ and 31.2％ respectively.There was significant difference in the BAFF-871 C/T genotypic frequency between the SLE and nonthrombosis normal individuals (P＜0.05).Conclusion The polymorphism-871 C/T of BAFF promoter is correlated with the pathogenesis of SLE.The gene may be a major susceptible gene for SLE in Chinses Han people.Further investigations may be needed.

Objective:To investigate the relationship of hypertension with osteoporosis(OP)and bone mineral density(BMD) in elderly type 2 diabetic women.Methods: A total of 179 elderly type 2 diabetic women were categorized into hypertension group(n=124)and non-hypertension group(n=55).Lumbar and hip BMD were measured by dual-energy X-ray absorptiometry.Prevalences of osteoporosis were compared between the two groups using Chi-square test,and BMD was compared using covariance analysis.The correlation between the osteoporosis and risk factors was analyzed using binary logistic regression method.Results: The prevalences of osteoporosis(total OP,lumber OP and hip OP) in non-hypertension group were higher than that of the hypertension group(Pt=0.037,Pl=0.042 and Ph=0.051,respectively).Lumbar and hip BMD in the hypertension group was higher than that in the non-hypertension group,and there were significant differences in L3 and L4 BMDs between the two groups(P3=0.040,P4=0.021);however,the difference disappeared after adjustment for body mass index(BMD).After adjustment for C peptide,the P value also increased,but not as obvious as after adjustment for BMI.Binary logistic regression analysis showed that OP was associated with age,BMI and osteocalcin,but not with hypertension.Conclusion: OP is associated with the age,BMI,and osteocalcin,but not with hypertension in elderly type 2 diabetic women.

Objective To assess the coordinated regulation and the molecular mechanisms of 17β-estradiol and 1,25-dihydroxyvitamin D3 [ 1,25-( OH ) 2 D3 ] on the proliferation and differentiation of osteoblastic MC3T3-E1 cells.Methods MC3T3-E1 cells were cultured in phenol-red free α-MEM medium supplemented with 10％ FBS,MTT assay was performed to determine the effects of 17β-estradiol and 1,25-( OH )2 D3 on MC3T3-E1 cells proliferation.After cells were treated with different agents,cell cycle related genes [ cyclin E,proliferation cell nuclear antigen ( PCNA ),and cyclin-dependent kinase inhibitor 2b ( Cdkn2b ) ] and markers of osteoblastic differentiation [ type Ⅰ collagen ( COL Ⅰ ),alkaline phosphatase ( ALP),osteopontin ( OPN ) ] were detected with SYBR green-based quantitative PCR.ALP activity was detected with BCIP/NBT method.Results 17β-estradiol could promote proliferation of MC3T3-E1 cells,which was accordant to its ability to increase cyclin E and PCNA and to inhibit Cdkn2b mRNA expression in MC3T3-E1 cells.However,1,25-( OH)2D3 had no effect on the proliferation of MC3T3-E1 cells and also did not enhance the proliferation of MC3T3-E1 cells stimulated by 17β-estradiol.On the other hand,17β-estradiol promoted the gene expression of differentiation markers Col Ⅰ,ALP,and OPN,and 1,25-(OH) 2 D3 synergistically increased the expression of these genes with 17 β-estradiol.Conclusion As two of the most important hormones which regulate bone metabolism,estrogen and vitamin D may coordinately promote osteoblast differentiation,but may not regulate osteoblasts proliferation synergistically.

Objective To investigate the clinical features and prognostic factors of nasal type NIGT cell lymphoma(NKTCL).Methods Records of 61 patients with pathologically confirmed nasal type NKTCL were reviewed.Detailed clinical and laboratory data were included in univariate analysis, and statistically significant factors in univariate analysis were then included in multivariate analysis.Results In univariate analysis,Ann Arbor stage,performance status,IPI,number of extra-lymphatic site,B symptoms,LDH and β-MG level.were found to be the prognostic factors associated with time to overall survival in nasal type NKTCL.In multivariate analysis, Ann Arbor stage,performance status,LDH and β2-MG level were independent prognostic factors of overall survival.Conclusion Ann Arbor stage,performance status,LDH and β2-MG level were demonstrated as independent prognostic factors of the overall survival in nasal type NKTCL.

Objective To investigate the effects of icarrin on the activity and protein expression of core binding factor otl(Cbfa1) in rat osteoblasts cultured in vitro,and to explore whether mitogen-activated protein kinase (MAPK) pathway is involved in this process.Methods Calvarial osteoblasts were obtained from newborn (<24 h) SD rats by trypsin-coUagenase digestion method.The second generation osteoblasts were cultured in the medium containing icariin (10 ng/ml) or estradiol (10-8 mol/L) with or without extracellular-signal regulated kinase (ERK) inhibitor (UO126) or p38MAPK inhibitor (SB203580).Nuclear protein was extracted from osteoblasts.And then the activity of Cbfa1 was detected by ELISA.The amounts of Cbfa1 protein were detected by Western blot.Results Calvarial osteoblasts were obtained successfully and were used in this study after indentified by alkaline phosphatase and mineralized nodus staining.Cbfa1 expression and the activity in osteoblasts were up-regulated by both icariin and estradiol (P<0.05).The effects were partly inhibited by addition of U0126or SB203580 (P<0.05).Conclusions Either icarrin or estradiol can stimulate the proliferation and maturation of cultured osteoblasts in vitro via up-regulating the activity and expression of Cbfal.The MAPK signal pathway inhibitor seems to partly decrease Cbfa1 activity.It suggests that MAPK pathway may be involved in the transduction of icariin's impact on proliferation and mineralization of osteoblasts.
