Environmental safety technologies of dry cleaning and risk assessment of solvent residue control embody the green consumption's social environmental beneficiary. The safety assurance of dry cleaning with the combination of life cycle analysis and clean production offer dry cleaning industries an efficient way to get rid of health, environmental and social problems from hazardous solvent on the basis of pollution prevention and treatment during production and consumption period.

AIM: To examine whether tolerogenic dendritic cells(DC) loaded with heat shock protein 60(HSP60) could restore endothelial function in hypercholesterolemic apolipoprotein E(apoE)-null mice.METHODS: Bone marrow derived DC of the mice was loaded with HSP60 and co-cultured with rapamycin to generate tolerogenic DC.The tolerogenic DC,DC loaded only with HSP60(DChsp) and saline were injected into the apoE-null mice at 6 weeks of age for two times at a one-week interval.C57BL/6 mice at the same age were taken as normal control two weeks after the last injection.Aorta was harvested for ex vivo vascular ring tension test.Immune parameters were also analyzed in vitro and in vivo.RESULTS: Compared with the non loaded DC,HSP60 pulsed DC expressed higher levels of CD86,and stimulated T lymphocytes to proliferation significantly,while the tolerogenic DC expressed lower levels of CD86,and inhibited T lymphocytes to proliferation.After immunization with different injection,Ach-induced relaxation was reduced significantly in(DChsp) group compared with saline group(P

OBJECTIVETo investigate the expression of transcription factor Sp1 in gastric cancer tissue and its correlation with prognosis.
METHODSSp1 expression patterns in specimens of 86 gastric cancers, 57 normal gastric tissues and 53 metastatic lymph nodes were detected by immunohistochemical method. The activity of Sp1 in the tumor and normal tissues was examined by electrophoretic mobility shift analysis (EMSA). The correlation between transcription factor Sp1 expression of tumors and patients' prognosis were statistically analyzed using Cox proportional hazard model.
RESULTSIn normal gastric tissue, Sp1 protein was predominantly expressed in the nuclei of cell located in the mucous neck region, but neither in the gastric pit cells with foveolar differentiation, nor in cells of the glandular epithelium with glandular differentiation. Strong Sp1 expression was also detected in tumor cells, but very weak or even no Sp1 expression in stromal cells or normal glandular cells surrounding the tumor. The median survival time of patients with negative, weak, and strong Sp1 expression was 43, 37, and 8 months, respectively (P < 0.01). Spl expression (P < 0.01) and stage (P < 0.001) were demonstrated as independent prognostic factor by multivariate analysis.
CONCLUSIONNormal and malignant gastric tissue are found to have its own unique Sp1 expression patterns. Sp1 expression may be used as an important survival predictor in human gastric cancer.
