Purpose To investigate the clinicopathologic features and immunophenotype as well as its association with EBV infection of lymphoepithelioma-like gastric carcinoma (LLGC). Methods The clinical pathological data were reviewed, morphological changes were observed and immunohistochemical staining was done in 6 cases of LLGC. The expression of EBV-encoded small RNA ( EBER) in the 6 cases of LLGC were carried out by in situ hybridization. Results All of the six patients were male, the age was arranged 47 to 68 years, with mean of 55 years. All of the six cases, the lesions were located in gastric body. Microscopically, the undifferentiated carcinoma cells were arranged in cords and nests, scattering in the lymphoid-rich stroma, occasionally poor development tubular struc-tures were seen in the near surface of mucosa. Lymphoid follicles could be seen with lack of fibrous tissues reaction in the tumor stro-ma. Immunohistochemical staining and in situ hybridization showed the tumor cells were diffusely positive for CKpan, CK19, CEA and EBER, but negative to CK7, CK20, CK5/6 and LMP1; interstitial lymphocytes expressed CD3 or CD20, while lost expression of EBER. Follow-up for 6-57 months, all of the 6 patients were survived without tumor. Conclusions The LLGC is a rare and unique subtype of gastric carcinoma with good prognosis, which is often associated with EBV infection.

Objective To evaluate the in vitro effect of heat shock protein 70(HSP70)on interleukin-6 (IL-6)expression by cultured fibroblasts from psoriasis vulgaris lesions(PFbs).Methods Fibroblasts were isolated from the lesions of patients with psoriasis vulgaris and subjected to a primary culture.After 3 to 5 passages of culture,the fibroblasts were collected and used in the next experiment.Some PFbs were cultured with different concentrations(5,10,20,30 mg/L)of HSP70 for 48 hours,or with HSP70 of 30 mg/L for different durations(3,6,12,24,48,72 hours);some PFbs were incubated with HSP70 of 30 mg/L for 24 hours after pretreatment with pyrrolidine dithiocarbamate(PDTC,a specific inhibitor of nuclear factor-kappa B)for 30 minutes.PFbs receiving no treatment served as the control.Enzyme-linked immunosorbent assay(ELISA)and semi-quantitative reverse transcription PCR were performed to measure the IL-6 protein expression in culture supematant and IL-6 mRNA expression by PFbs,respectively.Differences in the expression of IL-6 protein and mRNA between PFbs receiving different treatment were analyzed by using t test and Dunnett's t test.Results HSP70 significantly increased both protein production and mRNA expression of IL-6 in a time(0-48 h)-and dose(5-30 mg/L)-dependent manner.The expression levels of supernatant IL-6 protein and IL-6 mRNA were significantly higher in the PFbs treated with HSP70 of 10 mg/L for 48 hours than untreated PFbs((75.2 ± 15.4)ng/L vs.(47.2 ± 10.6)ng/L,0.439 ± 0.093 vs.0.249 ± 0.069,both P ＜ 0.05).A significant increase was observed as early as 6 hours in the level of IL-6 mRNA after the treatment with HSP70 of 30 mg/L,and 12 hours in the level of supematant IL-6 protein.Decreased supernatant IL-6 protein and IL-6 mRNA were noted for PFbs treated with PDTC and HSP70 of 30 mg/L compared with untreated PFbs((42.23 ± 9.41)ng/L vs.(68.40 ± 14.43)ng/L,0.144 ± 0.048 vs.0.295 ± 0.081,both P ＜ 0.05).Conclusion HSP70 may increase the expression of IL-6 mRNA and protein by cultured PFbs via the nuclear factor-kappa B pathway.

OBJECTIVETo study the change of WT1 gene expression during human leukemic K562 cell differentiation and apoptosis induced by bufalin.

METHODSCell viability was determined by trypan blue exclusion, cell differentiation and apoptosis by nitro blue tetrazolium (NBT) reduction test, morphology and flow cytometry, expression of WT1 protein by Western blot analysis, and expression of WT1 mRNA by reverse transcriptase-polymerase chain reaction (RT-PCR).

RESULTS(1) The cell proliferation was inhibited by bufalin and the IC(50) at 24, 48, 72 h were 0.026, 0.032 and 0.006 micro mol/L, respectively. (2) Bufalin induced K562 cell differentiation towards macrophage/monocyte within concentration from 0.01 to 0.05 micro mol/L and apoptosis at higher than 0.026 micro mol/L. (3) The expression of WT1 protein and mRNA were downregulated by bufalin in the initial stage of differentiation and apoptosis induced by bufalin.

CONCLUSIONK562 cell differentiation and apoptosis induced by bufalin might relate to the downregulation of WT1 expression.

Objective To investigate the genetic aberrations in extranodal marginal zone lymphoma of mueosa-associated lymphoid tissue (MALT) lymphomas from different sites of the body in Chinese patients. Methods Two hundred and seventeen paraffin-embedded MALT lymphoma specimens from 11 major sites were studied with interphase fluorescence in situ hybridization (FISH) to detect t(11; 18) (q21;q21)/API2-MALT1, t(1; 14) (p22; q32)/IGH-BCL10, (14; 18) (q32; q21)/IGH-MALT1 and BCL6 gene involved chromosome translocations. Results These translocations were mutually exclusive and detected in 21% (46/217) of the cases, including t(11;18) (q21;q21) API2-MALT1 13% (29/217), t (1;14)(p22 ;q32) IGH-BCLIO in 1% (3/217), t(14;18) (q32;q21) IGH-MALT1 1% (2/217), BCL6 involved translocation in 2% (4/217) and IGH-unknown translocation partner in 4% (8/217). t(11; 18) (q21;q21)API2-MALT1 was found with the highest frequency in MALT lymphoma from lungs (47% , 8/17) and small intestine (29%, 4/14), followed by salivary gland (17%, 1/6), stomach (14%, 12/84) and ocular adnexae (6% , 4/68). t(1 ;14) (p22;q32) was only detected in lungs (12%, 2/17) and stomach (1%, 1/84). t(14;18) (q32;q21) was mainly detected in lungs (6%, 1/17) and ocular adnexae (2%, 1/68). BCL6 gene involved translocation was detected in salivary gland (17% , 1/6) and stomach (4%, 3/84). Conclusions It is demonstrated that the four translocatidns occur with markedly variable frequencies in MALT lymphoma of different sites in Chinese patients. The distributions of these chromosome translocations in Chinese patients are slightly different from those reported in western patients.
