Aim Powdered injections of luotai consist of total saponins of panax notoginseng(PNS) which protect against ischemia injury from myocardial reperfusion injury.Methods ISO-induced acute myocardial ischemia model in rat was made, which decreased S-T sigments in ECG.Luotai after intravenous injection or oral can protect against S-T sigment significant reduction and ∑ST after ISO induced acute myocardial ischemia .Results Luotai 50 mg?kg-1 and 100 mg?kg-1 significantly inhibited S-T sigment decreases. Conclusion Luotai protect ISO induced acute myocardial ischemia and has dose-dependent effect.This ISO-induced acute myocardial ischemia model in rat has some significant advantages,for example,higher stability, good duplication, quickly filtrates, easily masters.

Objective To investigate the prevalence and major risk factors of peripartum thromboembolic disease in different regions of Guangdong province.Methods Data from 169 218pregnant women in different regions of Guangdong province from January 2005 to June 2010 were analyzed retrospectively.The prevalence and epidemiological characteristics of thromboembolic disease during pregnancy or puerperium were investigated.Results Of the studied population,( 1 )20 l cases ( 1.3‰ ) suffered from thromboembolic disease during pregnancy or puerperium including 128 cases of deep vein thrombosis (DVT),68 cases of cerebral venous thrombosis (CVT) and 5pulmonary embolism,the prevalence rates were 0.8‰,0.4‰,and 0.02‰ respectively.(2) Risk factors in different regions showed that,in the Pearl River Delta area,the major risk factors for DVT would include previous or family history of thrombosis,pregnancy complications,with medically involved diseases,prolonged bed rest and pregnancy weight gain ＞ 15 kg etc.While in castern,western,northern parts of Guangdong,the major risk factors for DVT would include pregnancy weight gain ＞ 15 kg,prolonged bed rest,preeclampsia,cesarean section and complications during pregnancy.In Pearl River Delta region,the major risk factors for CVT would include eclampsia,preeclampsia,pregnancy complications,prolonged bed rest ＞3 days,past history or family history of thrombosis.While eclampsia,preeclampsia,advanced age or younger age,pregnancy weight gain ＞15 kg,complications during pregnancy were the major risk factors for CVT in the eastern,western or northem parts of Guangdong.Conclusion Prevalence and major risk factors of peripartum thromboembolic disease in different regions of Guangdong were different.It was crucial to take effective measures in pregnant women with different epidemiological characteristics and risk factors to prevent and reduce the incidence of peripartum thromboembolic disease.

OBJECTIVE: To study the clinical effect of continuous subcutaneous insulin infusion (CSⅡ) versus multiple daily injection (MDI) on blood glucose control in children with type 1 diabetes mellitus (T1DM). METHODS: A retrospective analysis was performed on the medical data of 91 children with T1DM who were treated with CSⅡ for more than 1 year and 75 children with T1DM who were treated with MDI. The two groups were compared in terms of glycosylated hemoglobin (HbA1C) and the recurrence of diabetic ketoacidosis (DKA) to evaluate the difference in the efficacy during the 3-year follow-up. A survey was conducted for the children in the CSⅡ group and their family members to investigate the degree of satisfaction with insulin pump. RESULTS: There was no significant difference in age, sex, and course of diabetes between the CSⅡ and MDI groups at disease onset and in the first year, the second year, and the third year of follow-up ( CONCLUSIONS Children with T1DM treated with CSⅡ have a better control of blood glucose than those treated with MDI, and children and their family members are satisfied with CSⅡ treatment. Therefore, it holds promise for clinical application.
