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 discuss the application value of spiral CT tri-dimensional reestablishment in ankle joint fracture.[Method] For 42 cases,make X-ray picture and spiral CT scanning at adem position;compare it with CT tri-dimensional reestablishment and operation.[Result] CT tri-dimensional reestablishment has key directing meaning to ankle fracture and operation style.

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 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 study the bioactive constituents of the immature fruits of Citrus aurantium. Methods Silica gel and Sephadex LH-20 were used to isolate the constituents of this plant. The spectroscopic methods were applied for their structural elucidation. Results Four compounds were isolated from the ethanol extract of the immature fruits of C. aurantium. These compounds were elucidated as 3, 5-dihydroxyphenyl 1-O-(6′-O-trans-feruloyl)-?-D-glucopyranoside (Ⅰ), hesperetin (Ⅱ), 4′, 5, 7, 8-tetra- methoxyflavone (Ⅲ), and limonin (Ⅳ). Conclusion Compound Ⅰ is a new phenolic glycoside.

Objective To determine the prevalence and risk factors for latex glove allergy in clini-cal nurses. Methods A serf-administered questionnaire was used to collect the information about latex glove-related allergy among clinical nursing staff in 4 general hospitals in Zhanjiang, and the risk factors were calculated with logistic regression analysis. Results Latex glove-related symptoms were reported in 16.9% of 1469 nurses. Age, employment seniority, and positive rate of personal and family history of ana-phylaetie diseases in sensitized nurses were superior to those in unsensitized ones. The positive personal and family history of hypersensitivity diseases, allergy to drugs or other materials, and working time in a room were high risk factors for the development of latex glove allergy, but the average number of gloves used in a working day was the protective factor. Conclusions Clinical nurses belong to high risk latex sensitization population, and the main risk factor is the atopie subjects.
