As a distinct clinicopathological entity, mediastinal gray zone lymphoma cannot be classified by using differential diagnostic criteria. The cases represent a spectrum of tumors having characteristics of both primary mediastinal large B-cell lymphoma (PMBL) and classic Hodgkin lymphoma (cHL). In the 2008 WHO Classification, a novel category designated B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma (BCLu) has been created to include these neoplasms. The main features of BCLu are clearly different from those of conventional mediastinal large B-cell lymphomas. Diagnosis of BCLu requires a multiparameter approach incorporating morphological, immunophenotypic, immunohistochemical and other features. These lymphomas generally have a more aggressive clinical course and poorer outcome. There is no consensus on the optimum treatment, while the recommended therapies for aggressive B-cell lymphomas might be effective options.

Objective To estimate the effects ot rosiglitazone on cultured HaCaT human keratinocytes and their possible mechanism.Methods HaCaT cells were cultured and treated with different concentrations ( 10,20,40,80 μ mol/L) of rosiglitazone or solvent for 24,48,72 and 96 hours,respectively.Cell proliferation was detected with methyl thiazolyl tetrazolium (MTT) assay.Western blot was performed to measure the protein expression of β-catenin and cyclin D1.Results Compared with the solvent-treated cells,the proliferation of HaCaT cells was significantly inhibited by 18.9％,23.7％,35.1％ and 44.6％ (all P＜ 0.05) after treatment with rosiglitazone of 10,20,40 and 80 μmol/L,respectively,for 48 hours.The expressions of β-catenin and cyclin D 1 were significantly lower in rosiglitazone-treated HaCaT cells than in solvent-treated cells (all P ＜ 0.05).Conclusion Rosiglitazone could inhibit the proliferation of HaCaT cells,likely by downregulating the expressions of β-catenin and cyclin D 1.

Objective:to study cognitive impairment of patients with Alzheimer disease (AD). Method:62 patients with AD and 159 normal elderly were tested with MMSE. Result:The patients group had lower scores in all subtests except that of naming. Level of education had positive correlation with the total score, subscores of attention and calculation, understanding, and describe graph. Conclusion:MMSE can be used in clinical assessment of cognitive function of patients with AD.

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 observe clinical effects and safety of small dose of octreotide for preventing hyperamylasemia and acute pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP).METHODS:One hundred and twenty ERCP pa tients were selected from our hospital during Oct.2014-Jan.2015 and then divided in to observation group and control group in accordance with random number table,with 60 cases in each group.Both groups were given Diazepam tablet 10 mg+Meperidine hydrochloride tablet 100 mg+Phenobarbital scopolamine tablet 2 tablets 0.5 h before surgery for sedation and analgesia,and routine acid suppression and anti-infective therapy.Observation group was additionally given Octreotide acetate injection 0.1 mg hypodermically and then given Octreotide acetate injection 0.1 mg immediately after surgery,8 h after surgery.The levels of serum amylase and blood glucose were observed in 2 groups,and the occurrence of postoperative complication and ADR were recorded.RESULTS:Before operation,there was no statistical significance in the levels of serum amylase and blood glucose between 2 groups (P＞ 0.05).After operation,the level of serum amylase in control group was significantly higher than in observation group,with statistical significance (P＜0.05).There was no statistical significance in blood glucose level between 2 groups after operation (P＞0.05).The incidence of hyperamylasemia and ADR in observation group was significantly lower than in control group,with statistical significance (P＜0.05),and there was no statistical significance in the incidence of acute pancreatitis between 2 groups after operation (P＞0.05).CONCLUSIONS:Small dose of octreotide can effectively reduce the level of serum amylase and the incidence of hyperamylasemia after ERCP with good safety.

The aim of the present study was to work on the efficiency of differential diagnosis of native hapten-gel diffusion assay (NH-GD) on the background of vaccination with S2 or Rev.1.The conditions of NH-GD assay was firstly optimized,its sensitivity,specificity,repeatability and ability of differential diagnosis were determined respectively,and its test result was compared with that of fluorescence polarization assay (FPA).The results showed NH-GD assay with good specificity and repeatability could differentiate Brucella-infected antibody from vaccinated antibody after vaccination with S2 or 122 days after vaccination with Rev.1.And the result of NH-GD assay was highly consistent with that of FPA,which was simple to operate and needed a few simple equipment.Therefore,NH-GD assay was a good method for sheep brucellosis surveillance in China and especially suitable for application in grass-roots areas.
