Objective To investigate the expression of Interleukin 6 ( IL-6 ) and interleukin 10 (IL-10) in cerebrospinal fluid(CSF) in patients with primary central nervous system lymphoma.Methods Forty cases of primary central nervous system lymphoma ( PCNSL) , 11 cases of secondary central nervous system lymphomas( SCNS) , 20 cases of brain metastase, 20 cases of central nervous system infection and 16 cases of other nervous system disease( ONSD) were collected during the period from July 2013 to December 2015 in Fudan University Hua Shan Hospital North.Enzyme linked immunosorbent assay was used to detect the levels of IL-6 and IL-10 in serum and cerebrospinal fluid.The overall level of each group was compared using Kruskal-Wallis test.Two independent samples were compared by U Mann-Whitney test.The diagnostic value of IL-6 and IL-10 levels for PCNSL was evaluated by ROC curve.Results In PCNSL group, BM group, SCNSL group, CNSI group and ONSD group, the serum levels of IL-6 and IL-10 were not statistically significant ( H values were 4.165 and 5.368, respectively, P>0.05).IL-6 levels in CSF were significantly higher in CNSI[623.73 (1018.77-184.37) pg/ml] than those in other groups ( ZPCNSL =51.36, ZSCNSL =28.18, ZBM =51.50, ZCNSI =85.45, ZONSD =42.16, P<0.05 ) .The levels of IL-10 in CSF were significantly higher in CNSI and PCNSL than those in other groups ( ZPCNSL =74.50, ZSCNSL =34.68, ZBM =35.35, ZCNSI =72.95, ZONSD =15.66, P<0.05).The levels of IL-10 in CSF in PCNSL group[64.88(20.03-206.14)pg/ml]was significantly higher than in SCNSL group[6.28(2.78-18.87)pg/ml, Z=-3.753,P<0.05], BM group[7.30(3.72 -14.49) pg/ml, Z=-5.034,P<0.05] and ONSD group [3.14(2.931-4.20)pg/ml, Z=-5.786,P<0.05].The area under the ROC curve of IL-6 and IL-10 levels in CSF was 0.461 and 0.806 respectively for the diagnosis of PCNSL.When IL-10 was 19.62 pg/ml, the sensitivity was 77.5% ( 31/40 ) and the specificity was 70.1% ( 47/67 ) .The area under the ROC curve of CSF IL-6 and IL-10 levels was 0.861 and 0.718 respectively for the diagnosis of CNSI.When IL-6 was 155.12 pg/ml, the sensitivity was 80.0% (16/20) and the specificity was 90.8% (79/87).When IL-10 was 26.76 pg/ml, the sensitivity was 80.0% ( 16/20 ) and the specificity was 66.7% ( 58/87 ) . Conclusion The expression levels of IL-6 and IL-10 in CSF can be used as an indicator for the differential diagnosis of primary central nervous system lymphoma.

Objective To investigate the effects of compound Betamethasone on the expression of olfactory marker protein(OMP)in murine olfactory mucosa injured by influenza virus.Methods An animal model was developed by intranasal application of influenza virus to mice.Compound Betamethasone was injected i.p.(3.5 mg/kg)on day 2 and day 4 after the insult.The expression of OMP was tested by immunohistochemistry and Western blot.Results The expression of OMP was significantly downregnlated in the olfactory mucosa of influenza virus control group 1 and influenza virus control group 2;the expression of OMP was significantly upregulated in the olfactory mucosa of post-infection compound Betamethasone group 1 and post-infection compound Betamethasone group 2.Conclusion Compound Betamethasone can enhance the expression of OMP in the olfactory mucosa injured by influenza virus.

Objective To develop a quantitative assay method for the determination of tissue factor. Methods Lyophilized prothrombin complex was used as the source of factor Ⅶ,Ⅹ. Synthetic chromogenic substrate (S2222)was hydrolyzed into p nitroaniline. The absorbency of p nitroaniline measured spectrophotometrically at 405 nm is proportional to TF quantity in logarithm ( r =0.998). Results The linear range was from 10 U to 10 5 U. Low and high coefficients of variation were 10.3%, 6.6% within day and 18.1%, 10.2% day to day. Conclusions The method is very simple, sensitive, with good linearity, and applicable to quantitation of TF activity quickly.

Objective To study the offactory function test in Parkinson' s disease(PD), in order to promote the diagnosis of the PD. Methods Subjects included 95 middle-aged volunteers and 37 Pdpatients. A subjective olfactometry with T&T olfactometer was performed in all volunteers and patients.Olfactory event related potentials with isoamyl acetate were obtained in all volunteers and patients. Results The T&T olfactometer Results for the 2 sides were 4.6±1.1,4.4±1.2 in PD patients older than 70 years old and 3.9±1.7, 4.0±1.7 in those, respectively; while the data were 0.4±0.9,0.4±0.9 in volunteers older than 70 years, were 0.5±0.8,0.5±0.8 younger than 70 years old. There was a significant differencein T&T olfactometer Results between PD and volunteers (t=15.246,15.378,8.664,8.776, P<0.01). TheP2 latencies were respectively (734.9±143.2), (696.1±165.9) ms for the 2 sides in PD older than 70years, and (730.5±159.4), (719.5±159.2) ms in PD younger than 70 years;while they were (547.9±65.0), (558.5±56.3) ms, and (523.3±61.9), (526.8±62.0) ms in volunteers younger than 70 years.There was a significant difference in P2 latency between PD and volunteers (t = -3.940, -3.750,- 7. 514, - 8.205,P<0.01). Conclusions Olfactory dysfunction is an important index in PD. Olfactory function test is an useful method in the diagnosis of PD.

Early exercise training after stroke is a therapeutic strategy that has been paid w idespread attention. A series of studies found that early exercise training after stroke can increase expression of neurotrophic factors and maintain the integrity of the blood-brain barrier by inhibiting acute neuroinflammation and apoptosis, and reduce brain damage. This artice reviews the neuroprotective roles of early exercise training after stroke and their possible molecular mechanisms.
