OBJECTIVE: To analyze the pathogenesis and clinical manifestations of delayed encephalopathy after acute carbon monoxide poisoning, and to investigate the method of complex treatment and the factors influencing prognosis.DATA SOURCE: Related papers were searched by computer in Chinese Journal Full-text Database (CJFD) from January 1983 to October 2000 and CBMdise with the terms of "acute, carbon monoxide poisoning, delayed,encephalopathy", and the language of paper was limited to Chinese.STUDY SELECTION: The papers relevant to the pathogenesis, clinical manifestation, treatment and prognosis of acute carbon monoxide poisoning were collected preliming screening. Inclusion criteria: ① Randomized controlled trial. ② Blind method was not restricted. Exclusion criteria: The same researches repeated.DATA EXTRACTION: A total of 240 pieces of paper related to acute carbon monoxide poisoning induced eneephalopathy were collected, among which, 24 pieces accorded with inclusion criteria.DATA SYNTHESIS: The pathogenesis of acute carbon monoxide poisoning induced encephalopathy was relatively complex, which should be deeply recognized from the clinical manifestations such as symptom, sign,electroencephalogram, cerebral CT and MRL The therapeutic methods included ①Neural cell agonist, vasodilator, anticoagulant and vitamin ②High pressure oxygen ③ Ultraviolet blood irradation and oxygenation, UBIO. ④ Acupuncture therapy. The factors influencing prognosis of delayed encephalopathy after acute carbon monoxide poisoning were usually related to age, degree of poisoning, complications and cure time.CONCLUSION: Acute carbon monoxide poisoning can cause encephalopathy, which is the result of multiple pathogenesis. There is no special treatment for it until now, and complex treatment should be used, but the curative effect is not ideal, and intellectual disturbance and extremity function disorder of different degree might be left after treatment, and agrypnocoma would exist for a long time.

Objective: to study the relationship between immune complex(IC)and the origin of atherosclerosis(AS),and to evaluate the simvastatin's potential effect on immunomodulation. Methods: Thirty eight truebred New Zealand rabbits were randomly divided into four groups: control group,high-cholesterol fed group,simvastatin-protecting group and simvastatin-treatment group.the structural change of artery and the deposit of IC(and their classes)in plaque lesions of AS were analyzed with hematoxylin and eosin stain and immunohistochemistry. Results: plaque lesions of AS were obvious after 8-weeks high-cholesterol feeding.With the development of AS,the IC of IgG accumulated in plaque lesions,while the IC of IgM did not.The immunohistochemical stain was stronger in high-cholesterol feed group than that in the simvastain-intervening groups.The distribution of immune complexes was under the endothelium in the early plaque while mainly localized in the core or the shoulder of mature plaque lesions. Conclusion: The IC of IgG exists in the plaque lesions of AS.The IC is close related to the origin and the progress of AS.Simvastatin can inhibit the formation of IC as well as lowering the lipid levels and regressing the plaque,which maybe related to it's effect on the immunomodulation.

Objective:To investigate the effect of transfection with wild hepaCAM gene on biological behavior of the transitional cell carcinoma of bladder in vitro.Methods:Human TCCB cell line T24 was transfected with pEGFP-N2-hepaCAM,mock plasmid pEGFP-N2 with lipofectamine.Laser confocal microscopy was used to detect the location of hepaCAM in cells.Western bolt was used to determine the expression of target of hepaCAM in stable cells.The cell adhesive and motility ability were tested by cell spreading assay and matrigel invasion assay.Cell proliferation ability was investigated by MTT assay。Results:In well spread cells,hepaCAM localized on the perinuclear membrane,whereas in the cells which contacts,hepaCAM predominantly accumulated at the sites of cell-cell contacts on cell membrane.Cell clone with stable expression of hepaCAM,was acquired.In vitro experiments as cell spreading assays and matrigel invasion assays showed the cell adhesion and cell motility properties of hepaCAM group were apparently enhanced compared with the non-transfection or mock-vehicle groups.The MTT assay showed cell proliferation ability in the hepaCAM group was notably decreased when compared with the non-transfection or mock-vehicle groups.Conclusion:The hepaCAM gene can restrain malignant phenotypes of the human TCCB cells in vitro,and may inhibit the TCCB invasion and metastasis by influencing the function of some adherence and proliferation factors.[
