Objective To observe the protective effect of Mongolian medicine Carthamus tinctorius in acute liver injury induced by D-GlaN(D-galactosamine)in rat models. Methods The acute liver injury model was established by intragastric administration D-GlaN in rats. The levels of serum aspartate aminotransferase(AST),alanine aminotransferase(ALT),glutathione(GSH-Px),the content of tumor necrosis factor-α(TNF-α)in liver tissue and the apoptosis of hepatocytes were determined. Results Mongolian medicine safflower can significantly reduce the activity of serum ALT and AST and liver tissue GSH-Px,and the degree of cell apoptosis;however,no obvious change of the TNF-αcontent was observed. Conclusion The Mongolian medicine Carthamus tinctorius has protective effect in D-GlaN-induced acute liver injury rats probably via anti-oxi-dative and anti-apoptotic abilities.

Abnormal elevation and abnormal isoenzyme of non-specific esterase (?-NAE) are intimately associated with the genesis and development of cancer.Anti-GCBAP is a new kind of biological response modifier(BRM) which is separated from gastric cancer cells immunized animal spleen. As determined by clonogenic assay. Anti-GCBAP displayed highly-potent, specific cytotoxicity regarding to target cancer cells. In the present study, we have further investigated the effect of Anti-GCBAP on the ?-NAE isoenzymes in gastric cancer-bearing nude mice. The results demonstrated that in vivo adminstration of Anti-GCBAP can not only inhibit tumor growth in tumor-bearing mice, compared with control(p

Objective To identify the correlation between vitamin D prescription and recurrence in rheumatoid arthritis (RA).Methods A randomized controlled trial study was performed in 170 RA patients who were in remission during the past 2 months.According to the level of vitamin D,170 RA patients were divided into normal vitamin D group (84 patients) and deficiency vitamin D group (86 patients).Deficiency vitamin D group were randomly allocated to receive vitamin D treatment(vitamin D treatment group) or without vitamin D treatment (control group).In the 6-month follow-up period,the recurrence status was observed and compared.Results In the 6-month follow-up period,the recurrence rate of RA in normal vitamin D group was 16.7％(14/84),in vitamin D treatment group was 19.0％(8/42) and in control group was 29.5％(13/44),and there was no significant difference (P ＞ 0.05).In vitamin D treatment group,no hypercalcemia and hyperphosphatemia occured.The age,course of disease and remission time in recurrence patients of three groups were no significant difference (P ＞ 0.05).The level of vitamin D in recurrence patients of vitamin D treatment group was higher than that in recurrence patients of control group:(25.5 ± 8.9) ng/L vs.(20.9 ± 8.6)ng/L,and there was significant difference(P＜ 0.05).Conclusion Vitamin D deficiency is not identified to be a risk factor for RA recurrence.Vitamin D does not reduce the recurrence of RA.
