Crisis is an emergent event that threatens the national security, social regulation, civilian property and life, and needs urgent, decisive response in the condition of high instability. Crisis management should be prompt, active, honest, responsible and soluble, and should be carried out according to the model of preparation, reduction, response and recovery. SARS outbreak in China revealed constitutive defects in the immediate response for emergent public health event as well as crisis management. This paper provides some information for establishing the immediate response system for emergent public health event and crisis management.

Objective To assess the incidence of thrombocytopenia and abnormal coagulation,door to needle time (DNT),and safety in patients with ischemic stroke who receive intravenous thrombolytic treatment prior to the availability of blood platelet (PLT) and coagulation results.Methods Consecutive acute ischemic stroke (AIS) or transient ischemic attack patients within 12 hours of symptom onset who were admitted from January 2009 to March 2013 were retrospectively recruited.First laboratory reports in their medical charts were collected to assess the incidence of thrombocytopenia and abnormal coagulation.In the mean time,consecutive AIS patients who received intravenous thrombolysis at Huashan Hospital during the same period were retrospectively recruited.The thrombolytic procedures were further optimized since June 10.3760/cma.j.issn.1006-7876.2014.07.00626,2012.With informed consent,intravenous thrombolysis was initiated without PLT and coagulation results after certain previous history and medications were ruled out.Thrombolytic patients were divided into two groups based on the initiation of thrombolysis before or after PLT and coagulation results.Baseline demographic data,symptomatic intracerebral hemorrhage rates,mortality on the 7th day as well as functional outcome at 3 months were collected.DNT as well as efficacy and safety of thrombolysis therapy were compared between the two groups.Results Of 298 AIS patients within 12 hours of onset,8 had thrombocytopenia or abnormal coagulation.One hundred and twenty cases of intravenous thrombolysis patients were recruited.Waiting for PLT and coagulation results prolonged DNT than without waiting for them (90 min vs 59 min; U =870.000,P <0.01).There was no statistically significant difference in the rate of symptomatic intracerebral hemorrhage (sICH),early efficacy,7 d mortality and 3-month good outcome between two groups.Conclusions The incidence of thrombocytopenia and abnormal coagulation is low in AIS patients.Initiating intravenous thrombolysis prior to the availability of coagulation results can shorten DNT,while increased risks of sICH and 7 d mortality were not observed.

Objective: To compare the accumulative scores of cerebrovascular hemodynamic parameters (CVHP) in different populations and to analyze the relationship between the change of accumulative scores and the risk of stroke. Methods: A total of 10 565 participants aged 40 years and above were selected from a cluster sampling community-based population. Their risk factors were investigated and CVHP was evaluated. The CVHP scores were accumulated by a unified approach, and the incidence of stroke was followed up. The participants were grouped into health adult, single factor exposure, multiple-factor exposure, and newly developed stroke during the follow-up period. The differences of CVHP accumulative scores and the change law among the 4 groups were compared respectively according to age and sex. Results: The accumu-lative scores of the mean (SD) CVHP in the health adult, single factor exposure, multiple-factor exposure, and newly developed stroke groups were 86.44 (20.69), 72.07 (28.10), 60.82(34.64), and4.01 (29.36) in men respectively, and they were 83.95 (22.19), 67.97 (29.73),59.91 (31.34), and 42.64 (28.00) in women respectively, which had a tendency to gradually decrease. The accumulative scores of CVHP and their distributions at the same age stage in all the 4 groups had significant differences (P < 0.01 ). The accumulative scores of CVHP and their distributions for the same factors between all age groups also had significant differences (P <0. 01). Conclusions: The accumulative scores of CVHP had a tendency to gradually decrease from the health adults, risk factor exposure to high risk status before stroke. The decrease of the accumulative scores is closely associated with the increase of stroke risk, which can be used as a predictor of stroke.
