Objective To evaluate the cause and the treatment of the vagus nerve reflex in patients with hemoptysis during bron-chial artery embolization (BAE).Methods 1 12 patients with much hemoptysis were enrolled,9 of whom represented vagus nerve reflex in the process of interventional embolization.Results In 9 patients with mixed vagal reflex,5 occurred in the process of bron-chial artery embolization,1 in removing of sheath,1 in hemostasis by compression and 2 in returning to the ward.The intraoperative vagus reflex during BAE was related to over tension and unnormolized operation,and it improved by block of vagus nerve,raising blood pressure and fluid expansion without serious complications.Conclusion Vagus nerve reflex during BAE should be noticed, and early detection and timely intervention may improve its prognosis.

Objective To observe the effects of interleukin-1β (IL-1β) and pentylenetetrazol (PTZ) induced acute epilepsy and the dynamic expression of aquaporin-4 (AQP4) in hippocampus. To explore the role of IL-1β in the pathogenesis of epilepsy by regulating AQP4. Methods All rats were randomly divided into control group, IL-1β group, PTZ group, IL-1ra + PTZ group and dexamethasone + PTZ group. Observe the behavior of the rats within 60 minutes after injection and record seizure score in each group. Then immunohistochemistry and RT-qPCR were used to detect the expression of AQP4 at at 6 , 12, 24 and 36 h. Results Almost of rats in IL-1β group and PTZ group showed severe degree seizure. The rats in control group and dexamethasone + PTZ group showed no obvious seizure. The seizure of rats were more remarkable serious in PTZ group than that in the IL-1ra + pentylenetetrazole group (P < 0.05). Immunohistochemistry and RT-qPCR Show: the expression of AQP4 in hippocampus in PTZ group increased gradually after 12 h (P < 0.05), then reached in the peak after 24 h (P < 0.001). The expression of AQP4 in IL-1ra + PTZ group was lower compare with PTZ group in each time (P < 0.05). Although the expression of AQP4 in dexamethasone + PTZ group higher than the control group, it was not significantly different (P < 0.05). Conclusion The proinflammatory cytokine IL-1β break the balance of water in brain and increasing the concentration of extracellular excitatory amino acids or ions by upregulate the expression of AQP4 in order to promote the excitatory of neurons.
