莱姆病的研究进展

结合国内外对莱姆病的研究结果,从病原学、流行病学(地理分布、贮存宿主、传播媒介和易感人群)、发病机理、临床症状、诊断(包括病原学诊断、血清学诊断和分子生物学诊断)、预防和治疗等方面阐述了莱姆病的研究进展,旨在为该病的深入研究提供参考。     

Increased adrenaline to noradrenaline ratio is a superior indicator of antemortem hypothermia compared with separate catecholamine concentrations

The significance of urinary catecholamines and small gastric mucosal bleedings, Wischnewsky's spots, in postmortem diagnosis of hypothermia deaths was evaluated. Autopsy cases (n=358) were divided into hypothermia, suspected hypothermia, and control groups. The catecholamine levels did not correlate with the length of the postmortem period. The adrenaline to noradrenaline ratio was most effective in detecting hypothermia (68.9% sensitivity, 78.1% specificity). The median adrenaline concentrations were significantly higher in hypothermia than in control groups. The control group containing mostly sudden cardiac deaths with no cold exposure had a noradrenaline level comparable to the hypothermia groups. The sensitivity and specificity of determining Wischnewsky's spots in hypothermia deaths were 63.9% and 88.3%, respectively. The adrenaline to noradrenaline ratio is more suitable in proving antemortem cold stress than either of these independently, and its diagnostic value is comparable to that of Wischnewsky's spots.
