Objective To explore statin dosages for targeting goal of LDL-C lowering on the basis of stroke risk stratification and the dosage-effective relation of statin and LDL-C lowering in Chinese patients with ischemic stroke and transient ischemic attack (TIA).Methods This is a prospective and open clinical trial patients with ischemic stroke/TIA within 6 months were enrolled and the dosages of atorvastatin were calculated based on risk stratification according to "Chinese Consensus for Prevention of Ischemic Stroke/TIA with Statin" (Chinese Consensus).A dose of 10 mg of atorvastatin daily to target LDL-C goal was takenas the standard dosage targeting goal (SDTG).Patients taking this dosage of atorvastatin constituted a SDTG group.Those who needed a daily dose of 20 mg or more of atorvastatin were randomized into an intensive dosage targeting goal (IDTG) group ( atorvastatin 20-80 mg/d) and a standard dosage non-targeting goal (SDNTG) group (atorvastatin 10 mg/d without targeting goal).All patients took atorvastatin for 12 weeks.The primary outcome was the rate of targeting goal for LDL-C lowering at 2,4 and 12 weeks,respectively and the secondary outcome was the occurence of recurrent stroke and other vascular events within 12 weeks.The main safety endpoint was serial adverse events including symptomatic intracranial hemorrhage.Results Altogether 102 cases were enrolled and 99 cases were followed up for 12 weeks.According to the Chinese Consensus,the rate of high risk,very high risk- Ⅰ and very high risk- Ⅱ was 44% ,28% and 28%,respectively.Targeting rate for LDL-C lowering was 77% -85% at each time point in the SDTG and IDTG groups ,being significantly higher than those in the SDNTG group ( 12% -16%,P < 0.01 ).No significant difference was found concerning the occurrence of recurrent stroke,other vascular events and safety endpoints among the three groups.The amplitude of LDL-C lowering was 32%-35% ,46%-49% ,51%-52% and 60%-65% with corresponding to daily dosage of 10 mg,20 mg,d0 mg and 80 mg atorvastatin.Conclusions At least more than half of the patients after iscbemic stroke/TIA need intensive statin therapy to target the LDL-C lowering goal.The dosage- effective relation of atorvastatin and LDL-C lowering in Chinese is similar to the reported data in other races.

Objective To analyze the clinical effects of thrombolytic therapy in patients with ischemic in-hos-pital stroke (IHS). Methods The clinical data were collected from patients with ischemic IHS in the last five years. The patients were divided into thrombolysis group and non-thrombolysis group, according to the use of recombinant tissue plasminogen activator (r-tPA) treatment. The clinical outcomes were measured by the modified Rankin scale (mRS) at discharge. Results There were a total of 121 patients in this study. There were 6 patients in thrombolysis group and 115 patients in the non-thrombolysis group, respectively. Six patients (100%) in the thrombolysis group achieved favor-able outcomes (mRS 0~2) at discharge whereas only 42 patients (36.5%) in the non-thrombolysis group achieved fa-vourable outcomes. The rate of favorable outcomes was significantly higher in the thrombolysis group than in the non-thrombolysis group (P<0.05). Conclusions R-tPA thrombolytic therapy can improve the prognosis of patients with ischemic IHS.
