Objective To investigate the effect of mild therapeutic hypothermia for different lengths of time on cerebral edema and hypoxia-inducible factor 1 α (HIF-1α),vascular endothelial growth factor (VEGF) expressions following intracerebral hemorrhage (ICH) so as to explore possible mechanism for better application of mild hypothermia.Methods ICH models were made in rats by stereotaxically injecting autologous artery blood into right caudate nucleus.Forty male Sprague-Dawley (SD) rats were randomly (random number) divided into 5 groups (n =8 each):sham-operated (sham),normothermic (NT),hypothermic-1 hour (MH1),hypothermic-2 hours (MH2),hypothermic-4 hours (MH3).Normothermic and sham-operated animals were kept at (37.0-± 0.2) ℃ of body temperature.Animals in the hypothermic groups received immediately and rapid cooling after ICH and kept at (33.0 ± 0.5) ℃ of body temperature for 1,2 and 4 hours respectively.Rats were sacrificed at 48 hours after cerebral hemorrhage.Then brain water content and BBB permeability were determined.Quantitative real-time PCR and Western blot were used to analyze the expression of HIF-1α and VEGF.Results The content of brain water,Evans blue concentration in brain,and the mRNA expression and protein levels of HIF-1α and VEGF were noticeably higher in NT group than those in sham group (P ＜0.01).There were statistically significant difference in the expression of HIF-lα mRNA and protein but little difference in other indicators between MH1 group and NT group.Compared with NT group,MH2 group and MH3 group brought about an improvement in BBB permeability and remarkable down-regulation of protein levels and expression of HIF-1 α and VEGF mRNA,whereas there were no statistically significant difference in expression of indicators between the two groups.Conclusions Mild therapeutic hypothermia induced rapidly and immediately after ICH could limit the development of brain edema in rats by down-regulating expression and protein levels of HIF-1 α mRNA,and in turn suppressing the evaluation of VEGF mRNA and protein expression.The brain edema was effectively reduced in animals treated with hypothermia for 2 hours' or 4 hours ' duration with little difference in magnitude of reduction in brain edema between these two modalities of hypothermia.

Objective To explore the incidence,features and outcomes of in-hospital sudden cardiac death (SCD) in order to determine the predictors of survival. Methods The clinical data of 69 patients with cardiac arrest hospitalized from January 2008 through December 2010 were retrospectively analyzed.Information on genders,age,types of arrhythmia was collected and further analyzed to determine these factors associated with the occurrence and outcomes of in-hospital cardiac arrest. Results The overall incidence of SCD was 47.3 / 100 000 per year and 17.4％ of them.survived at discharge.The occurrence rate was higher in male than that in female (66.7％ vs.33.3％,P ＜0.01 ),whereas difference in gender did not affect the discharge rate ( P ＞ 0.05 ). Survivors from in-hospital cardiac arrest were significantly younger than non-survivors (man:62.57 ± 12.83 years vs.75.56 ± 10.55 years; women:60.36 ± 13.24years vs.69.53 ± 11.72 years,P ＜ O.01 ).From 62 ECG records of SCD patients,the incidence of nonshockable rhythms was higher than that of shockable rhythms.Compare to the non-shockable rhythms,the shockable rhythms brought a higher rate of restoration of spontaneous circulation (ROSC) (54.5％ vs.24.5％,P ＜0.05),whereas survival rates at discharge between two groups were not statistically different ( 18.2％ vs.18.4％,P ＞ 0.05 ).Conclusions Non-shockable rhythms were more common in patients suffering from in-hospital cardiac arrest.Although defibrillation treatment contributed benefit to ROSC among patients with ventricular fibrillation or pulseless ventricular tachycardia,high-quality CPR and post-cardiac arrest care may play a more critical role in the outcomes of in-hospital sudden cardiac death.

Objective To validate near-infrared cerebral topography (NCT) as a practical toolin tracing the regional hemodynamic changes during normal ischemic stroke model of rat. Method Middle cerebral artery occlusion (MCAO) and photosensitizer induced intracranial infarction model of rat were established. The geometric shape and infarction area were measured by NCT, functional magnetic resonance imaging (fMRI), and TTC stained anatomical imaging techniques. Result In photosensitizer induced infarction model, the correlation between anatomical infarct area and NCT image area for infarct focus were r= 0.897 for 24 h group (P<0.05) and r=0.906 for 2 months group (P<0.01),respectively. The correlation between anatomical infarction area and NCT image area for infarct focus were r=0.820 for normothermia group (P<0.05) and r= 0.851 for hypothermia group (P<0.05), respectively. The correlation between fMRI and NCT image area for infarction focus were r= 0.874 for normothermia group (P<0.05) and r= 0.782 for hypothermia group (P<0.05),respectively. Conclusion Measurement with NCT for infarction focus matched well with fMRI and anatomic sample in rats. NCT technique might be a practical tool for short-term prediction of stroke and the rehabilitation after stroke in real time.

Nanobodies are derived from the variable domain of the heavy-chain antibodies (HCAbs) that occur naturally in the serum of Camelidae. They are the smallest antibody fragments capable to bind antigens. With the characteristics of their increased solubility, increased domain stabilities, nanomolar affinities, easy crossing the blood-brain barrier, easy generation, engineering, optimization and tailoring, easy humanization, nanobodies have extensive application prospects in diagnosis and detection. Although nanobody has demonstrated tremendous success, a number of practical challenges limit its broader applications in disease diagnosis and detection, including construction of a phage library and selection of nanobody fragments with high affinity and immunogold labeling technique. Here, we review several recent findings on the use of nanobodies in molecular diagnostics and suggest some practical strategies in resolving the current challenges in this attractive research area, particularly to optimize the affinity, solubility, humanization of nanobodies.

Objective Acute poisoning is frequently encountered at emergency department. This study was to investigate the epidemiology and characteristics of patients with acute poisoning who were treated at the Emergency Center, Fujian Provincial Hospital, China. Method We retrospectively analyzed the gender, age, causes of poisoning, types of poisons, poisoning route, emergency diagnoses, outcomes, and prognoses of these patients.Results Altogether 2867 patients with acute poisoning were treated from January 2004 to December 2009. The ratween 18 and 40 years old. The incidence of acute poisoning was as high as 11.33% in January each year. The incidence of poisoning was in a descending order: alcohol poisoning (54.55%), medication poisoning (25.95%), pesticide poisoning (5.65%), and drug poisoning (4.88%). Most (56.44%) of the patients with drug poisoning were under 25 years and their mean age was significantly lower than that of patients with medication poisoning or alcohol poisoning ( P ＜ 0.01 ). Approximately 69.54% of the patients were followed up after emergency treatment, 30.39% were hospitalized, and four patients died. Conclusions Acute poisoning is largely alcohol poisoning and medication poisoning in a city. The emergency green channel "pre-hospital emergency care-emergency department-hospital treatment" can significantly improve the survival rate of patients with acute poisoning.
