Objective To study the chronic neurotoxicity of aluminum through observing the adverse effect of long term intake of aluminum on the memory of rats.Methods 40 Wistar rats were randomly divided into 4 groups and given Al2(SO4)3 through drinking water for 6 months,the concentration of Al3+ in the waters were 0.12 mg/L,40 mg/L,400 mg/L and 2 000 mg/L respectively,then passive avoidance tests were carried out.One month before pregnancy,the dams were given Al3+ of 40 mg/L and 2 000 mg/L respectively,after the offspring were born,the group given high[Al3+] was subdivided into two groups,one continuously drank the water with high [Al3+],the other drank the water without Al3+.The dams drinking water with low [Al3+] and their offspring continued to drink the same water as before.At the age of three months,all the offspring were examined with passive avoidance tests.Results The memory acquirement in all adult rats were not abnormal,but memory retention were severely damaged (P0.05).The rats continuously drinking water with high [Al3+] after birth had significant damage both in memory acquirement and in retention (P

Objective To study on the relationship of PTEN with clinicopathological parameters and prognosis of esophageal squamous cell carcinoma patients.Methods The expression of PTEN was detected in 62 cases of esophageal squamous cell carcinomas by immunohistochemistry.Results(1)PTEN expres- sion is negatively correlated with the depth of invasion,lymph node metastasis,distant metastasis,pTNM stage and degree of differentiation.(2)The difference of survival is significant between high and low expres- sion groups.Conclusion PTEN is correlated negatively with the clinicopathological parameters reflecting the malignant biological behavior,and is one of the significant prognostic predictors by univariate analysis.

OBJECTIVETo investigate the intervention effect and mechanism of compound Ginkgo biloba (CGB) preparations on nonalcoholic fatty liver disease (NAFLD).

METHODThe C57BL/6 mouse NAFLD model was induced with high fat diets. Since the 2nd week after modeling, the mice were orally administered with 600 and 200 mg x kg(-1) x d(-1) CGB for eight weeks. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), cholesterol (CHOL) and LPS in serum, as well as pathological changes and expression of tumor necrosis factor-alpha (TNF-alpha) in hepatic tissues were observed. Changes in intestinal tight junction proteins ZO-1, Occludin, Claudin-1 in intestinal tissues were determined under microscopy.

RESULTCompared with the normal group, the model group showed obvious fatty degeneration in rat livers, with notable increase in TNF-alpha expression (P < 0.01), significant increases in ALT, AST, TG, CHOL and LPS in serum (P < 0.01, P < 0.05), injury in intestinal tight junction proteins, and remarkable declines in ZO-1, Occludin and Claudin-1 (P < 0.01). Compared with the model group, CGB high and low dose groups showed obvious relieves in fatty degeneration in rat livers and injury in intestinal tight junction proteins, significant reductions in TNF-alpha expression (P < 0.01, P < 0.05) and AST, TG, CHOL and LPS in serum (P < 0.01, P < 0.05) and remarkable increases in ZO-1 and Occludin expressions (P < 0.05).

CONCLUSIONCGB can protect intestinal tight junction proteins, reduce intestinal leakage, relieve fatty degeneration and inflammations in livers and prevent NAFLD occurrence and development.
