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.
2.Study on memory T cell subsets in peripheral blood of patients with multiple sclerosis
Chinese Journal of Immunology 1999;0(12):-
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 investigate the influence on the behavior of withdrawal and relapse after deep brain stimulation of bilateral nucleus accumbens in morphine-dependent rats. Methods The rats with a strong unconditioned preference were discarded in preconditioning test, the selected rats were distributed into five groups randomly. After operation,morphine hydrochloride was injected subcutaneously into SD rats for 12 days (once every day,initial 5 mg/kg,increasing by 5 mg/kg per time,stable in 20 mg/kg ). A modified electrical circuit was used to procedure the DBS,the parameter was 130 Hz,150 A,60 s,l h/d,14 d. CPP test was used to exam the effect of DBS. A minor morphine dose (3 mg/kg) was injected to induce the behavior of relapse, and CPP was tested again after 24 h. Two-way ANOVA was performed on the data with Bonferroni posttest. Result ①After CPP training,CPP score of group morphine, morphine + sham and morphine + DBS was ( 155. 87 ± 20. 45 ) s, (107.33 ± 18.10)s,(135.45 ±22.09)s,and had significant difference with group of control( ( -70.34 ± 15.40) s)(t = 9.45,P<0.01; t = 6.94,P<0.01;t = 8.04,P<0.01).②After 7 days' DBS,the CPP score in group of morphine + DBS reduced significantly compared to group of morphine( t = 4.21, P<0.01) and morphine + sham( t=1.10, P<0.05).0n the 14th day,there was more pronounced reduction ( t = 5. 15, P<0.01; t = 3.92, P< 0.01). ③ 24 hours after the minor morphine dose was injected,the CPP score in morphine + DBS didn't increase significantly, and had significant difference with group of morphine ( t = 4.04, P<0.01) and morphine + sham ( t= 4. 13, P<0.01). Conclusion DBS bilateral nucleus accumbens in morphine-dependent rats can interfere the behavior of morphine-induced CPP and relapse.

Objective:To analyze the effect of PAK4 interruption by microRNA-199a/b-3p (miR-199a/b-3p) on migration and invasion of hepatocellular carcinoma (HCC).Methods: To test targeting of PAK4 by miR-199a/b-3p,we used luciferase assay in HEK293T cells cotransfected miR-199a/b-3p mimcs and pmirGLO-PAK4 3′UTR.The expression of PAK4 in SMMC-7721 transfected with miR-199a/b-3p was detected by Western blot.The biology behaviors of SMMC-7721 cells transfected with miR-199a/b-3p or PAK4 Si were analysed by cell migration assay and invasion assay.Results:MiR-199a/b-3p could suppress the mRNA and protein ex-pression of PAK4 by targeting PAK4 3′UTR,and the downregulating PAK 4 expression suppress the migration and invasion of SMMC-7721 cells.Conclusion: MiR-199a/b-3p could suppress the expression of PAK 4, which are considered key HCC suppressors and inhibit the migration and invasion of HCC cells.

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.
