Objective To investigate the effect of tripterygium glycosides(TG) combined with tanshinone Ⅱ A(Tan Ⅱ A) on the level of tumor necrosis factor-α(TNF-α) ,yon willebrand factor(vWF) in serum in adjuvant ar-thritis(AA) mice. Methods Animal model of adjuvant arthritis was indwecd,after 3 weeks administration the mice were kiued and get serum. TNF-α, vWF were assayed by ELISA. Results TNF-α: model group and Tan Ⅱ A group are significantly higher than control group,TG + TanⅡ A group are lower than the other groups,there is no significant difference between control group, MTX group,TG group; vWF: model group have the highest vWF level, has significant difference between control group ,MTX group, TG group, TG + Tan Ⅱ A group and Tan Ⅱ A group, TG + Tan Ⅱ A group are lower than the other group. Conclusion TG + Tan Ⅱ A can improve cardiovascular damage of rheumatoid arthritis by means of inhibiting inflammatory factor expression.

OBJECTIVE: To study the expression of BIRC6 in renal cancer tissues and investigate the effect of BIRC6 silencing on apoptosis and autophagy of 786-O cells. METHODS: Twenty surgical specimens of renal cancer tissues and adjacent renal tissues were collected from Meizhou People's Hospital between February, 2016 and December, 2018 for detection of BIRC6 protein expression using immunohistochemistry. Renal cancer 786-O cells were transfected with a control small interfering RNA (siRNA) or BIRC6 siRNA RESULTS: The expression of BIRC6 protein was significantly higher in renal cancer tissues than in the adjacent renal tissues. Western blotting showed that siRNA-mediated silencing of BIRC6 significantly lowered the expression of BIRC6 in 786-O cells. In the cells with BIRC6 silencing, treatment with 12.5, 25, 50, 100 and 200 μg/mL 5-FU resulted in significantly higher proliferation inhibition rates than in the cells transfected with the control siRNA ( CONCLUSIONS Interference of BIRC6 mediated by siRNA can inhibit autophagy and promote 5-FU-induced apoptosis to enhance the sensitivity of 786-O cells to 5-FU.

Gamma band oscillation (GBO) and sensory gating (SG) are associated with many cognitive functions. Ketamine induces deficits of GBO and SG in the prefrontal cortex (PFC). However, the time-courses of the effects of different doses of ketamine on GBO power and SG are poorly understood. Studies have indicated that GBO power and SG have a common substrate for their generation and abnormalities. In this study, we found that (1) ketamine administration increased GBO power in the PFC in rats differently in the low- and high-dose groups; (2) auditory SG was significantly lower than baseline in the 30 mg/kg and 60 mg/kg groups, but not in the 15 mg/kg and 120 mg/kg groups; and (3) changes in SG and basal GBO power were significantly correlated in awake rats. These results indicate a relationship between mechanisms underlying auditory SG and GBO power.
