Sedation monitoring of the critically ill children must be individualized and continuous. Electroen-cephalography-derived method———bispectral index( BIS) is one of the most widely used objective sedation monitoring methods in recent years,permitting continuous monitoring. Some studies reported the correlations between BIS and the clinical scales were varing. The BIS value of 70 or so may distinguish between adequate and inadequate sedation. BIS has some unique advantages over other objective methods. Many factors may influence the right interpretation of BIS. On the whole, the researches and applications of BIS are mainly in adults, the experience is relatively less in critical ill children. This article reviews the studies of BIS in critical ill children for sedation monitoring.

Food intake,energy expenditure and body adiposity are homeostatically regulated.Hypothalamus and brainstem are key brain regions of the system.In the state of hunger or satiety,the neural and hormonal messages from the gut regulate energy homeostasis through reflection or direct effect on the hypothalamus and brainstem,Which is referred to as brain-gut signaling.New researches on the special physiological functions of gut hormones are expected to offer a target for anti-obesity drugs.

ObjectiveTo explore activity characteristics of diverse autonomic nervous system of armymen with different mental quality levels during dread emotion processes.MethodsMental Quality Questionnaire of Armymen was used to select participants.The activities of the diverse autonomic nervous system of armymen withdifferent mental quality levels during dread emotion processes were discussed by physiological - psychological experiments.Results ( 1 ) Under neutral condition blood volume pulse (BPV) is greater in low mental quality group( ( -0.87 ±0.64)mm Hg) than in high( -0.28 ±0.24)mm Hg).(2) During dread emotion processes the normalized low frequency spectral component(LF) and skin conductance (SC) are greater in low mental quality group ( (6.54 ± 2.96) nU),(0.78 ± 0.11 ) umho) than in moderate ( ( 1.32 ± 1.25 ) nU,( (0.22 ± 0.15 ) umho) and high ((3.51 ±2.28 )nU,((0.30 ±0.12) umho).(3) During dread emotion processes the recovery time of HR and the average recovery time of skin conductance( SC ),skin temperature( ST),blood volume pulse(BVP) and HR are greater in low mental quality ( 61.58 ± 35.66 ) s,( 36.78 ± 18.58 ) s ) than in high ( ( 22.36 ± 6.87 ) s,(56.87 ± 23.98 ) s).(4) In emotional arousal,and low mental quality (0.88 ± 2.54 ) in neutral conditions change their arousal'was significantly greater than the middle (0.57 ± 2.88) and high psychological quality group (0.15 ± 1.87) ; Low mental quality group (2.17 ±2.39) under the conditions of pleasure in the dread was significantlygreater than the middle ( 1.87 ± 1.45 ) and high psychological quality group ( 1.24 ± 1.66).ConclusionThe findings indicate that armymen with low mental quality is more likely to show corresponding physiological arousal and alert status in face of the neutral or weak emotional stimuli.When facing dread emotional stimuli,they would show stronger physiological arousal mainly basing on the excitement of sympathetic nerve system,and such statuswould last much longer to bring about more fierce pain experience.

Objective To analyze the clinical characteristics of infective endoearditis complicated with intracranial hemorrhage.Methods The clinical characteristics,brain CT and MRI results and prognosis of 7 patients with infective endocarditis and intracranial hemorrhage admitted between January 1991 and May 2015 were retrospectively analyzed.Results All seven patients presented varying degrees of fever,cardiac murmur and neurological symptoms.The continuous fever lasted from 21 d to 227 d (average 91 d).Mitral valve (4 cases) and aortic valve (3 cases) were the most common affected ones.The brain CT or MRI scan presented intracranial hemorrhage in 6 cases.More than 2 hemorrhage locations were found in 5 patients and parietal lobe was most common one (4 cases).All patients were treated with antimicrobial agents and three patients underwent valve replacement surgery.Three patients were cured and another 2 died due to fatal hemorrhage.Conclusions Patients with long fever history and ineffective antimicrobial treatment are prone to intracranial hemorrhage.Brain CT or MRI scan need be performed in infective endocardits when neurological symptoms are present,and brain angiography should be also considered if necessary.
