0.05).Conclusion:The decrease in 4-1BB expression,rather than the GITR expression,on CD4+CD25high T cells of MS patients suggests that 4-1BB may be involved in the lower immunoactivity of the cell population,while the GITR may play a minor or fine role in the immunoregulation of the cells.

Objective:To explored the mechanisms that lead to the changes of the memory T cell subsets.Methods:By using of flow cytometry and enzyme-linked immunosorbent assay(ELISA), we detected the percentage of memory T cell subsets and plasma concentration of interleukin-15(IL-15) in peripheral blood of MS patients and healthy individuals. Furthermore, MS patients were subdivided into both relapse-remission MS(RRMS) and chronic progressive MS(CPMS) group according to the clinical features.Results:Compared to healthy controls, there was an increase and decrease in CD8~+T_ CM and terminal effector memory CD8~+T cell in MS patients(P

Objective To research the location in cerebral circulations of recurrent stroke.Methods We included patients with acute cerebral infarction from the Department of Neurology of People's Hospital of Peking University within three years.We followed up the patients by telephone and electronic medical record to determine whether they belong to recurrent group or not.We recorded the clinical and image variables of recurrent group.We classified the recurrent group by whether the loci of recurrent stroke is in the same circulation.We determined the independent risk factors of the same circulation loci by Cox regression.Results There are 106 cases of recurrent stroke.Within 5 years,46.2％ of the cases had recurrent loci in the same circulation as first stroke loci.53.8％ of the cases had recurrent loci in the different circulation from first stroke loci.According to logistic regression,whether the recurrent loci was in the same circulation was not related to age,sex,hypertension,diabetes mellitus,smoking,but related to the survival time.The shorter the survival time was the more ratio of same circulation loci happened.The longer the survival time was the more ratio of different circulation loci happened.37％ of cases with recurrent strokes happened in the first year occupied the most cases in the 5 years.Conclusions With the long time study of the location of recurrent stroke,we get the conclusion that the longer the survival time is the more ratio of different circulation stroke happen.So we emphasize the importance of medicine for the stroke in long time.At the same time we conclude the rationality of endovascular treatments within 1 year from first stroke because recurrent loci is more often in the same circulation in 1 year.

Objective:To analyze the expression levels of serum microRNA-199a/b-3p ( miR-199-3p) in hepatocellular carcinoma (HCC) patients and to explore whether miR-199a/b-3p could be a novel biomarker of early HCC.Methods: Patients with normal liver,liver cirrhosis and early HCC in clinic were included in this study.Blood samples of the patients were collected for analy-sis.Real time quantitative PCR technique was used to measure the expression level of serum miRNA-199a/b-3p.The AFP expression was got from clinical data.Results: Comparing with normal liver and liver cirrhosis patients, miRNA-199a/b-3p presented lower expressions in early HCC patients (P<0.05);the accuracy and positive rate of serum miR-199a/b-3p detection in cirrhosis and HCC were better than AFP detection.Conclusion:Data indicated that miRNA-199a/b-3p had diagnostic value for indicating liver cirrhosis and early HCC.

Objective To investigate the influence of transforming growth factor-?1(TGF-?1) on macrophage scavenger receptor (ScR) class A and B(ScR-B,CD36) in order to provide theoretical foundation for expounding the formation and therapy of atherosclerosis(AS).Methods THP-1 derived macrophages were divided into control group and experimental group,the cells in experimental group were treated with 3.0 mg?L-1Anti TGF-?1 Ab,the cells in control group were treated with 3.0 mg?L-1 IgG. The 125I-acetylated low density lipoprotein (125I-Ac-LDL for ScR-A) and 125I-oxidized low density lipoprotein (125I-Ox-LDL for CD36) uptaking (including 4℃ binding,37℃ association and degradation) were measured respectively.Influence of anti TGF-?1 antibody (Anti TGF-?1 Ab) on the ScR-A and CD36 mRNA expressions in THP-1 derived macrophages was measured meanwhile,respectively.Results Compared with control group ( binding: 8.23 ?g?g-1 ?1.24 ?g?g-1 protein,association:45.69 ?g?g-1 ?6.92 ?g?g-1 protein,and degradation: 112.18 ?g?g-1 ?20.15 ?g?g-1 protein),Anti TGF-?1 Ab increased 125I-Ac-LDL binding(48.67 ?g?g-1 ?6.52 ?g?g-1 protein),association (412.30 ?g?g-1?12.21 ?g?g-1 protein),and degradation (896.48 ?g?g-1 ?32.74 ?g?g-1 protein) significantly (P

Objective To compare the Poser and the McDonald diagnostic criteria for multiple sclerosis (MS).Methods Sixty-seven patients with clinical features suggestive of MS were re-evaluated by 2 neurologists utilizing both the Poser and the McDonald criteria.The Fisher' s exact test was used to statistically analyze the data from assessment by these two criteria.Results By the Poser criteria, 34 patients were classified as clinically definite MS, 24 patients as laboratory supported definite MS and 9 patients as possible MS.Under the new McDonald criteria, MS was diagnosed in 36 patients and 31 patients had possible MS.The results revealed significant differences in diagnosing MS between these 2 criteria (OR=5.549, 95% CI 2.37-13.00, P<0.01).Conclusions These 2 criteria showed remarkable differences in diagnosing MS, in particular definite MS, possibly due to greater reliance on paraclinical evidences in the Poser criteria and more stringent gnidlines of magnetic resonance imaging (MRI) in the McDonald criteria.The analysis of cerebrospinal fluid may increase the diagnostic rate of MS and specify pathologic abnormalities in MRI to some degree.

Objective:To investigate the expression of microRNA-199a/b-3p (miR-199a/b-3p) in hepatocellular carcinoma ( HCC) tissues,and to explore the relationship with clinical outcomes. Methods: Real time quantitative PCR technique was used to measure the expression of miRNA-199a/b-3p in HCC tissues. The correlation between miR-199a/b-3p expression and the clinic pathological features of patients were analyzed. Results: Comparing with adjacent control, miRNA-199a/b-3p presented lower expressions in HCC tissues (P<0. 05);lower miR-199a/b-3p was found correlated with metastasis and poor survival. Conclusion:MiR-199a/b-3p take a crucial role in HCC metastasis and recurrence.
