This study was designed to evaluate whether the maximum thickness of subarachnoid blood is an independent prognostic marker of mortality after traumatic subarachnoid haemorrhage. Multivariate analysis showed the maximum thickness of subarachnoid blood was an independent predictor of death versus survival 1 month after injury and was inversely associated with Glasgow Coma Scale (GCS) score. Receiver operating characteristic curve analysis showed that maximum thickness of subarachnoid blood > 6.7 mm immediately after non-surgical resuscitation predicted 1-month mortality with 83.9% sensitivity and 67.1% specificity; its predictive value was similar to that of the GCS score. Addition of maximum thickness of subarachnoid blood to the GCS score did not significantly improve predictive performance. Hence, the maximum thickness of subarachnoid blood is a new independent prognostic marker of mortality and might become an additional, valuable tool for risk stratification and decision making in the acute phase of traumatic subarachnoid haemorrhage. © 2011 Field House Publishing LLP.

This study evaluated interleukin (IL)-11 as an independent prognostic marker of mortality following intracerebral haemorrhage (ICH). Plasma IL-11 levels in patients with ICH were significantly higher than in healthy controls. Multivariate analysis indicated that plasma IL-11 level was an independent predictor for mortality within 1 week of ICH onset and was positively associated with haematoma volume. Receiver operating characteristic curve analysis identified that a baseline plasma IL-11 level > 20.9 pg/ml predicted mortality within 1 week of ICH onset with 81.2% sensitivity and 74.1% specificity. The area under the curve for IL-11 level was significantly smaller than that for the Glasgow Coma Scale score, but similar to that for haematoma volume. IL-11 did not, however, significantly improve the predictive value of the Glasgow Coma Scale or haematoma volume. Thus, IL-11 may be considered as a new independent prognostic marker of mortality and an additional valuable tool for risk stratification and decision-making in the acute phase of ICH. © 2011 Field House Publishing LLP.

Objective To analyze the incidence of cerebral vasospasm (CVS) in patients with traumatic subarachnoid hemorrhage ( t -SAH), time windows of CVS as well as the risk factors. Method A total of 98 patients , with t -SAH admitted from June 2007 to December 2008, were enrolled for this prospective study. The hemodynamics of middle cerebral artery (MCA) in these patients was monitored with trancranial Doppler (TCD) daily for 7 days after admission and on the 14th day of hospital stay. The incidence of cerebral vasospasm (CVS) in patients widi traumatic subarachnoid hemorrhage (t-SAH), time windows of CVS as well as the risk factors were analyzed. Results Of them, 41 patients (41.8%) had CVS. The flow velocity of MCA in patients with GCS≤8 was significantly higher than that in patients with GCS≥9. Classified by t-SAH cumulative blood Hijdra method, 2 (4.44%) of 45 patients(45.9%) with scores 6 or less, 9 (29.0%) of 31 patients (37.8%) with scores 6 - 13, and 8 (36.4%) of 22 patients (20.0%) with scores 13 or more had CVS. Severe CVS occurred in 13 (35.1%) of 37 surgical patients (37.8%), and local cerebral infarction occurred in four surgical patients after symptomatic treatment. The flow velocity of the MCA was significantly higher in surgical patients than that in non-surgical patients 3 days after admission. Conclusions The severity of original trauma, bleeding, location of t-SAH and operation are the major risk factors to lead to CVS in patients with t-SAH. Attention should be paid to those risk factors during the treatment of patients with t-SAH. Source

To investigate the mechanism of oridonin (ORI)-induced autophagy in prostate cancer PC-3 cells, PC-3 cells cultured in vitro were treated with ORI, and the inhibitory ratio of ORI on PC-3 cells was assayed by 3-4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide. The ultrastructural changes of the cells were observed under light microscope, scanning electron microscope (SEM), and transmission electron microscope (TEM). Acridine orange (AO) staining was used to observe the acidic vesicular organelles (AVOs). The level of autophagy-related proteins, MAP1-LC3, was detected by Western Blot, and RT-PCR was used to detect the level of mRNA of beclin 1. After ORI treatment, the proliferation of PC-3 cells was inhibited significantly in a concentration and time-dependent manner. SEM examination revealed cellular shrinkage and disappearance of surface microvilli in ORI-treated cells. Under TEM examination, the nuclei exhibited chromatin condensation and the appearance of a large number of autophagosomes with double-membrane structure in cytoplasm. AO staining showed the existence of AVOs. The expression of LC3 and the mRNA level of beclin 1 was increased by ORI. Furthermore, autophagy inhibitor 3-methyladenine reversed the increase of beclin 1 mRNA. The growth of PC-3 cells was inhibited, and autophagy was induced by ORI, indicating ORI may have a potential antitumor effect. © 2011 Wiley Periodicals, Inc. Source
