Objective To study the characteristics of the transcranial electric stimulation(TES)-elicited motor evoked potentials(MEP)recorded from different points of the diaphragm,and to determine the optimal record- ing site in the diaphragm.Methods One EEG electrode was placed subcutaneously in the midline of the skull as stimulation electrode and another EEG electrode was inserted into hard palate submucously as cathode in 30 male rats.And single square wave electrical pulse was used for stimulation.The stimulation intensity was 15 mA,the du- ration of the pulse was 0.2 ms,and the stimulating interval was 200 ms.The concentric needle electrode were insert- ed into the following eight sites:the medial,intermediate,lateral crura of the diaphragm,the junction of the posterior axilla line and the inferior border of the eleventh rib,the junction of the anterior axilla line and the inferior border of the ninth rib,the junction of the intermediate line of the clavicle and the inferior border of the eighth rib,the junction of the para-sternal line and the inferior border of the seventh rib,the pars sternalis.The MEP was recorded from each point,respectively.The optimal sites of the diaphragm MEP were found and recorded.Results The MEPs were re- corded from each of the 8 sites of the diaphragm in all the rats after TES.There was no statistically significant differ- ence among the latencies of every site.But the amplitude varied from 6.08?0.46 mV in maximum along the inferior border of the ninth rib at the anterior line of the axilla to the minimum of O.91?0.03 mV at the pars sternalis. Conclusion It is safer to insert the needle along the inferior border of the ninth rib at the anterior line of the axilla, because there was certain distant from the folding part of the pleura and the amplitude of the recorded wave at this point is maximal.

Objective To explore the clinical prognostic significance of arterial blood lactate level and early lactate clearance rate in elderly septic patients. Methods Totally 82 elderly septic patients who were admitted into emergency department were enrolled.Their arterial blood lactate levels were tested at admission and 6 hours later. Early lactate clearance rate was calculated as following:(lactate level of admission minus lactate level of 6 hours later) /lactate level of admission ×100 ％. Heart rate and blood pressure were recorded at admission,and the acute physiology and chronic health evaluationⅡ (APACHE Ⅱ ) score was evaluated in the first 24 hours.28 days after admission was the end of research.Patients were divided into survival group (n=59) and death group (n=23).Taking 10％ as cut-off,patients were divided into high lactate clearance (≥ 10％) group (n=59) and low lactate clearance (＜10％) group (n=23).Values of arterial blood lactate level,APACHE Ⅱ score and early lactate clearance to predict the prognosis of elderly septic patients were determined by ROC curves. Results Arterial blood lactate level was lower in survival group than death group[(2.4± 1.7)mmol/L vs.(3.9±3.2)mmol/L,P＜0.01].Early lactate clearance was higher in survival group than death group [(339.0 ± 28.0) ％ and (300.0 ± 81.0) ％,P ＜ 0.01].Mortality of high lactate clearance group was decreased as compared with low lactate clearance group [18.6％ (11/59) and 52.2％ (12/23),P＜0.01].The thresholds of early lactate clearance to predict mortality of elderly septic patients were 24.0％ (sensitivity 72.9％,specificity 65.2％) which was more valuable than APACHE Ⅱ score ( sensitivity 65.2 ％,specificity 57.6 ％). Conclusions Arterial blood lactate level and early lactate clearance were meaningful predictors for prognosis of elderly septic patients.
