小剂量长春新碱对小鼠M1细胞的分化诱导作用研究

目的：利用培养小鼠髓性白血病（M1细胞）来检测小剂长春新碱（VCR）对小鼠M1细胞分化诱导功能。方法：分观察组对照组，观察组使用VCR1次5ug后进行吞噬功能实验，及对细胞形态的观察与空白对照组比较。结果：发现使用小剂量长春新碱后小鼠M1细胞诱变细胞增多，吴噬功能增强，结论：说明小剂量长春新碱对培养小鼠M1细胞有一定诱导功能，诱导其向粒细胞、吞噬细胞方向转化，在临床上白血病的治疗有一定的作用。     

Balloon Catheter with Extra-amniotic Saline Instillation: a Method of Induction in Pregnancies at 41 or More Gestational Weeks

Summary: One hundred five women with a documented pregnancy of 41 weeks' gestation or more, admitted for induction of labour by balloon catheter with extra-amniotic saline instillation, were retrospectively compared to 196 women admitted in spontaneous labour at the same gestational age, with regard to mode of delivery. The success rate of the induction group was 97.1%. The mode of delivery did not differ significantly between the 2 groups. The Caesarean section rates were 11.4% in the induction group versus 9.7% in the spontaneous group. The mode of delivery after induction of labour by balloon catheter with extra-amniotic saline instillation and simultaneously commenced intravenous oxytocin infusion, in pregnancies of 41 weeks or more, is similar to that of spontaneous deliveries at the same gestational age.

女性飞行学员高空飞行生理生化耐受能力研究

为从高空缺氧耐力训练前后生理、生化角度探讨中国女飞行员驾驶战斗机的可行性,在地面模拟高空缺氧及高空飞行训练前后行心电图、心率、血氧饱和度、血压、血尿酸(BUA)、肌酸激酶(CK)、血红蛋白(Hb)、乳酸(BLA)、肌酐(Cr)和天冬氨酸转氨酶(AST)测定,并与男飞行学员的测定结果比较.发现男女飞行学员的心电图、心率、血氧饱和度、血压、Cr、CK、BUA和AST均无显著性差异;女飞行学员在高空耐缺氧Hb代偿反应高于男飞行学员(P<0.05),而BLA水平低于男飞行学员(P<0.05).认为中国女飞行学员在生理生化耐受能力上能胜任飞战斗机.     

脑干梗死的MRI和MRA征象

目的：探讨脑干梗死的MRI和MRA征象特点。方法：搜集我院1998年～2002年49例经MRI和MRA检查并经临床治疗证实的脑干梗死病例，其中21例行Gd-DTPA增强扫描，对比临床症状进行分析。结果：中脑梗死11例，桥脑梗死32例，延髓梗死6例。病灶直径以6～15mm为主，病灶形态主要因为不规则斑片状。病灶信号为长T1、长T2信号，行Gd—DTPA增强扫描，大部分呈斑片状或环状强化。MRA检查异常发现主要为椎动脉、基底动脉的狭窄或闭塞，基底动脉纡曲扩张。结论：脑干梗死主要因为椎-基底动脉异常，病灶部位可提示其临床意义。
