Objective To investigate the effects of 1,25-dihydroxyvitamin D3[1,25(OH)2D3] on regulatory T cells(CD4+CD25+ Foxp3+ T cell)and airway inflammation in asthmatic rats. Methods Asthmatic models were established in 28 rats with ovalbumin as sensitinogen,and four groups were randomly divided(n=7).1,25(OH)2D3 was orally administered 1 h before challenge in treatment group 1,dexamethasone was subcutaneously injected 1 h before challenge in treatment group 2,both 1,25(OH)2D3 and dexamethasone were given 1 h before challenge in treatment group 3,while no medicine was administered 1 h before challenge in group 4(asthmatic control group).The levels of IL-4 and IL-10 in bronchoalveolar lavage fluid(BALF) were detected,the total cell numbers were obtained and the eosinophil count was performed.The ratios of Treg to CD4+ T cells in peripheral blood and spleen mononuclear cells were measured with flow cytometry,and the mRNA expression of IL-10 and Foxp3 in lung tissues was detected.Wistar rats without asthma were served as normal controls(n=7). Results There were significant differences between asthmatic control group and normal control group in each parameter.Compared with asthmatic control group,the total cell number and eosinophil count decreased,the level of IL-4 decreased and the level of IL-10 increased in BALF in treatment groups.The ratios of Treg to CD4+ T cells in peripheral blood and spleen mononuclear cells significantly increased,and the mRNA expression of IL-10 and Foxp3 in lung tissues increased in treatment groups compared with asthmatic control group.There was no significant difference between treatment groups and normal control group in each parameter. Conclusion Administration of 1,25(OH)2D3 increases the proportion of Treg and expression of Foxp3 mRNA in peripheral blood and spleen in asthmatic rats.1,25(OH)2D3 has a regulatory effect on Treg,and may serve as a potential therapeutic approach against asthma.

0.05).However,neither CpG-ODN nor hTNF-? failed in improving the expression rates of CD1a.Conclusions CpG-ODN,like hTNF-?,has remarkable im- munostimulatory effect on the differentiation and maturation of monocyte-derived DC from patients with chronic hepatitis B.

Objective To develop an effective way to evaluate the accurate platelet count in a patient with anticoagulants-induced pseudothrombocytopenia (PTCP).Methods It was studied that various anticoagulants effect on the platelets count for an infrequent patient with anticoagulants-dependent PTCP. When vitamin B6,aminophylline,gentamicin and amikacin were separately added to four anticoagulated blood samples from anticoagulants-dependent patient within 15 min after blood withdrawal,platelets count and morphological changes of blood cells after 4 hours of incubation at room temperature were investigated. The best anti-aggregating agent and its optimal concentration among them were explored.Results The four anticoagulants all could not inhibit the aggregation of the patient's platelets.Only amikaein among the above anti-aggregating agents can prevent and dissociate the aggregation of platelets without apparent morphological changes of blood cells and the platelet counts was stable within 4 hours after blood drawn when amikacin was added either before or after blood sampling.With increasing the concentration of amikaein,the platelet counts increase and then tend to be stable.The optimal concentration of amikacin is 5 mg/ml blood.Conclusions The supplementation of amikaein either before or after blood sampling is a useful method for the diagnosis anticoagulants-dependent PTCP and for the eva/uation of platelet counts in infrequent patients with anticoagulants-dependent PTCP.

ObjectiveTo study the effects of tumor-associated calcium signal transducer-2 (TROP-2) gene small interfering RNA(siRNA) on adhesion and invasion of human breast cancer cell. MethodsReal time PCR was used to evaluate the TROP-2 mRNA of seven human breast cancer cell lines Bcap-37 ,LCC1 ,MCF-7 ,MDA-MB-231,MDA-MB-435, MDA-MB-468 ,and ZR75-1. The cell line of TROP-2 highest expression was transfected with different dose of TROP-2 siRNA. The expression of TROP-2 mRNA and protein were determined by Real-time quantitative PCR and immumoflurescence method. The cell adhesion was evaluated by MTT assay,and invasion was exmined by hoyden chamber,respectively. Results Cell line MCF-7 showed the highest elevation of TROP-2 mRNA in seven breast cancer cell lines. The results from real-time quantitative PCR and immumoflurescence method showed that TROP-2 mRNA and protein reduced in time-and dose-dependent manners( P ＜ 0.01 ;P ＜ 0.01 ). The adhesive rate of siRNA groups(5 nM,10 nM,and 20 nM)was(52.9 +2.5)％ ,(25.6 ±2.3)％, ( 12.8 +2.2)％ (P ＜0.01 ) ,respectively.The transwell results showed that the invasion cells was(78 ± 17), (39 ± 15), ( 19 ± 16), ( 136 +25 ) and( 139 ±21 )in different groups(5,10,20 nM siRNA,and controls) ,respectively(P ＜0.01). ConclusionTROP-2 gene might play an important role in adhesion and invasion of human breast cancer cell. siRNA targeted TROP-2 could effectively inhibit adhesion and invasion of human breast cancer cell.

Objective: The study was designed to evaluate the changes and significance of circulating CD4~+CD25~+ and CD8~+CD28~- regulatory T cells (Tregs) in patients with multiple myeloma (MM).Methods:CD4~+CD25~+ and CD8~+CD28~-Tregs in peripheral blood of 38 patients with MM and of 20 healthy doners were measured by flow cytometry.Serum albumin and β_2-MG in patients with MM were measured using bromocresol green method,transmission turbidimetry respectively.Results:Compared to those of the controls,the proportions of CD4~+CD25~(+/high),CD4~+CD25~(high) CD127~(low) and CD8~+CD28~-Treg cells in newly diagnosed MM patients were elevated.Furthermore,the proportions of CD4~+CD25~(high) and CD4~+CD25~(high)CD127~(low) Tregs in each clinical stage were elevated when compared to those of the controls.The number of the Tregs were increasing with clinical stages and were significantly higher in stage Ⅲ MM than in stageⅠ MM;In stageⅡand Ⅲ MM,there were also elevated proportions of CD8~+CD28~- Tregs,increasing with clinical stages.However,there were no differences when compared between stage Ⅰ MM and the controls;Both the proportions of CD4~+CD25~(+/high) and CD4~+CD25~(high)CD127~(low) Tregs in active MM were not different from stable MM,although all of them were higher than those of controls.The proportion of CD8~+CD28~- Tregs was higher in active MM than in stable MM and controls,but there were no differences when compared between active and stable MM.The proportions of both CD4~+CD25~(high) Tregs and CD4~+CD25~(high)CD127~(low)Tregs had negative correlation with the levels of serum albumin.Conclusion:MM patients have elevated levels of circulating CD4~+CD25~+ and CD8~+CD28~-Tregs,which may be an important mechanism of MM immune evasion,and may be associated with clinical stages,disease progression and prognosis of MM to some extent.
