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

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 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.

Ginseng root saponins ( GRS ) was extracted from native ginseng.The dosage used was calculated according to the content of saponins.Immunosuppression in mice was induced in 15 days after implar- ting Ehrlich ascites carcinoma (EAC) subcutaneously in armpit, and in 5-11 days after implanting EAC into peritoneal cavity. GRS administered orally 50mg/kg- for 8 days did not prevent the atrophy of the thymus in tumor-bearing mice but rather aggravated it. GRS administered orally 50mg/kg for 14 days partially restored the suppressed phagocytosis of peritoneal macrophages in tumor-bearing mice. GRS administered orally 50mg/kg for 6 days somewhat restored the suppression of hemolysin formation in tumor-bearing mice 5 days after implanting EAC, But GRS given in the same route and dosage for 9 days, showed no effect on the suppression of hemolysin formation. GRS administered orally 50mg/kg for 10 days partially restored the suppression of delayed hypersensitive reaction in tumor-bearing mice.

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.
