脑出血患者的护理体会

脑出血起病急骤，病死率较高，后遗症较多，且大多数患者死于并发症，所以脑出血患者的临床护理工作在整个治疗过程中都比较重要。     

高效液相色谱法测定白狼毒中月腺大戟素A的含量

目的 建立白狼毒药材中月腺大戟素A的含量测定方法.方法 采用高效液相色谱法,色谱柱为Agilent Zorbax SB-C18 (4.6 mm× 150 mm,5 μm),流动相为乙腈∶0.1％甲酸水溶液=55∶45,等度洗脱,流速1.0mL·min-1,检测波长为290 nm,柱温25℃,进样量20 μ上L,运行时间为20 min.结果 月腺大戟素A与周围干扰峰达到基线分离,线性范围为4.545～227.3 μg·mL-1,相关系数r=0.999 9;日内、日间精密度均小于2％;平均回收率为(99.1±3.4)％(n=6),狼毒大戟2个批次药材及月腺大戟对照药材中月腺大戟素A含量分别为(56.73±1.09)、(18.98±2.11)及(235.2±2.4) μg/g(n=6).结论 该法简便快捷、测定结果准确,重复性好,可用于白狼毒药材中月腺大戟素A的含量测定.

心肌梗死合并糖尿病患者QT间期和QT离散度的改变及不同治疗方法对其的影响

Objective To compare the QTc and QTcd between type 2 diabetic and non-diabetic patients with post-myocardial infarction (post-MI) ,and to compare the QTcd in type 2 diabetic patients with post-MI treated with insulin,sulfonylurea,mefformin,or diet alone. Methods We measured the QTc and QTcd through simultaneous 12-lead Electrocardiogram in 138 post-MI patients,including 70 type 2 diabetic (of which,23 were assigned to re-ceive insulin,20 glipizide,16 mefformin,11 diet control) and 68 non-diabetic patients. Result Compared with post-MI patients without diabetes,those with type 2 diabetes had significantly higher QTc [(377.2±24.3) ms vs (342.9±27.5)ms,t=7.79,P<0.01] and QTcd [(48.8±19.7)ms vs (40.3±26.6)ms,t=2.14,P<0.05]. There were no significant difference between the mefformin group and the diet control group (P>0.05). The QTc and QTcd in the insulin group were significantly higher than those in the other three group s(P<0.05),and the QTc and QTcd in the glipizide group were higher than those in the mefformin group or diet control group(P<0.05,and P<0.01,respectively). Conclusion Type 2 diabetes is associated with an additional increase in the QTcd in post-MI patients,suggesting higher mortality risk in post-MI patients with type 2 diabetes. Insulin and glipizide may in-crease the QTc and QTcd in post-MI patients with diabetes. These effects were more significant in the insulin therapy group.
