Abstract:
Objective: To study the changes of the intrinsic electrophysiological characteristics of cerebellar Purkinje cells during the stage of the elevation of intracellular Ca2+ through micro-injected of IP3 receptor excitomotor of Purkinje cells in cerebellar vermis.Methods: The sagittal slices of cerebellar vermis(400 μm) were prepared.The recordings of threshold potential of firing spike and absolute refractory period following each spike of cytoplasmic Ca2+ elevation cells were conducted in whole-cell model with an Axoclamp-2B amplifier;and electrical signals were inputted into pClamp 9.2 for data acquisition and analysis of inter-spike interval and standard deviation of spike timing.The changes in the intrinsic electrophysiological properties at Purkinje neurons during the elevation of intracellular Ca2+ were examined.Results: Shortly after the elevation of intracellular Ca2+,compared with before,refractory period of sequential spikes was shorten,the threshold potential of firing spikes was lower(P<0.001).Conclusions: The elevation of cytoplasmic Ca2+ alters the refractory period and threshold potential of sequential spikes,leads to increase of the excitability and deteriorated spike encoding of cerebellar Purkinje cells.

Abstract:
Objective: To observe the therapeutic effect of ulinastatin on acute lung injury/acute respiratory distress syndrome(ALI/ARDS).Methods: Thirty-four patients with ALI/ARDS were randomly divided into treatment group(n=17) and control group(n=17).The control group received only the routine therapy,and the treatment group were given ulinastatin(200 ku intravenously,once every 8 hours,and continued for 10 days) in addition to the routine treatment.The efficacy was assessed in both groups.The parameters of heart rate,respiratory rate,oxygenation,average arterial blood pressure and arterial blood gas were monitored.Serum levels of tumor necrosis factor-α(TNF-α),interleukin-1(IL-1) and IL-6 were measured on admission,the day 4 and the day 7 in both groups.Results: Before treatment,the TNF-α,IL-1 and IL-6 levels were not significantly different between the ulinastatin group and the control group(P>0.05);but descended significantly after treatment in the ulinastatin group(P<0.01),as well as the respiratory rate,heart rate,and the average arterial blood pressure.The blood gas analysis proved that PaO2 and PaO2/FiO2 increased significantly in the treatment group compared with those in the comparison group(P<0.01).Conclusions: Ulinastatin may significantly inhibit the production of inflammatory cytokinases and thus prevent the systemic injury by inflammatory response and improve the prognosis of ALI/ARDS.
