Objective: To explore the predictors of the non-survivable patients with severe cerebral infarction after mechanical ventilation. Methods: The clinical data of 36 patients with acute cerebral infarction who had tracheal intubation were analyzed retrospectively. The patients were divided into survivor (n = 18) group and non-survivor group (n = 18) according to their prognosis. The observational endpoint was at day 60. Patients' Glasgow Coma Scale (GCS) score, respiratory function (blood gas pH value, oxygen partial pressure, carbon dioxide partial pressure, and oxygenation index), and the causes of death before tracheal intubation were documented. Results: The mortality at day 60 after mechanical ventilation was 50% in patients with severe cerebral infarction. The median GCS score was 3. 6 ± 1. 0 in the non-survivor group, and the median GCS score was 6.3 ± 1.2 in the survivor group before tracheal intubation. Oxygen partial pressure and oxygenation index presented to decrease in both groups before the tracheal intubation. The median oxygen partial pressure in the survivor and non-survivor groups were 69 ± 17 and 52 ± 7 mm Hg, respectively; and the oxygenation indexes were 170 ± 31 and 109 ± 34, respectively. The univariate analysis showed that the patients' GCS scores decreased before the tracheal intubation. The decrease of oxygen partial pressure and oxygenation index were the important factors for predicting mortality. The multivariate regression analysis showed that the patients' GCS score (P = 0.015) and oxygen partial pressure (P = 0.026) before the tracheal intubation were an independent factors for predicting the mortality in patients with cerebral infarction at day 60 after the mechanical ventilation. Conclusion: For patients with severe cerebral infarction, the mechanical ventilation support may contribute to decreasing the mortality, particularly in patients whose respiratory system complications have resulted in deterioration of the disease. The aggregate analysis has showed that the patients' severity of conscious disturbance and the oxygenation parameters before the tracheal intubation may contribute to predicting the prognosis.

BACKGROUND:Bioimpedance method can be used to extract physiology and pathology information relative to the gastricmotility states,to investigate the courses of contraction,peristalsis,transmission and emptying of the stomach,to measure andevaluate gastric motility function.However,early studies mainly focused on the emptying of the stomach,and few studies onevaluation of gastric motility by extracting gastric motility information.OBJECTIVE:To understand the gastric motility from electricity-mechanism composite concept and to establish a noninvasive,convenience measurement method of gastric motility impedance.METHODS:Based on the characters of gastric motility impedance signal,a measurement method of impedance gastric motility isintroduced.Some foundation experiments about the gastric emptying measurement,the gastric motility compare between fastingand repast,the gastric motility comparison of healthy volunteers during different periods and some medicine effects on gastricmotility have carried out.The gastric motility measurement of the patients with functional dyspepsia and gastric motility evaluationfor the patients with erosive gastritis had been reported.RESULTS AND CONCLUSION:Using electrical bioimpedance method,according to the electrical property of the stomach tissueor the food in stomach and the change rules of the property,the physiology and pathology information relative to the gastricmotility states can be extracted,the courses of contraction,peristalsis,transmission and emptying of the stomach can beinvestigated and noninvasive measure and evaluation of gastric motility function can be realized.

ObjectiveTo explore the relationship between the changes of neuro-electrophysiology and prognosis in children with Guillain-Barr? syndrome(GBS).MethodsThirty-eight children with GBS were divided into group A(rapid recovery,n=16) and group B(slow recovery,n=22) according to the time required for podosoma motor function recovery,at the same time,they were divided into the better prognosis group(n=22) and the worse prognosis group(n=16),for analyzing the difference between group A and B in terms of age,preceding infections,maximal Hughes grades and neuro-electrophysiology including motor conduction velocity(MCV),distal complex muscle action potential(dCMAP) and F wave,and investigating the related factors with the prognosis of GBS.Results1.MCV of tibial nerve was(40.2?2.53) m/s and(33.4?2.46) m/s in group A and group B,respectively;MCV of peroneal nerve was(45.2?3.23) m/s and(38.3?2.16) m/s in group A and group B,respectively,and the difference between group A and group B was significant(Pa0.05);abnormal rate of F wave(68.42%) was higher than abnormal rate of MCV(42.11%) and dCMAP(42.11%)(Pa
