出血性疾病的治疗

出血仅是一个症状,引起出血的病因却是十分复杂的。重症的出血常不容寻找出血的原因必须先行对症止血。如压迫出血部位近心端动脉可达止血效果;粘膜部位渗血(如鼻腔)用油纱布填压效果亦佳,在纱布条上加上些肾上腺素或类凝血酶效果更佳。对内脏部位的出血则需使用一些药物。1.立止血Reptilase:系从巴西蛇毒液中分离提纯的类凝血酶。它可增加血小板粘附力及凝聚力,并且只在出血部位激发白色血栓形成;它可作用于组织凝血系统的因子Ⅶ、Ⅴ及血液凝血系统的血小板因子Ⅲ、Ⅴ,并可直接作用于激活组织     

“健康”中老年人行为类型特征与心脑血管病危险因素的关系

目的：探讨中山市“健康”中老年人行为类型特征与心脑血管病危险因素的关系。方法：采用行为类型问卷,以945名广东中山市古镇“健康”的35－64岁中老年人进行类型调查,并对行为类型与血脂,血液流变学指标,血糖,血压及心电图是否正常的关系进行了分析。结果：B型性格女性明显多于男性;随着年龄增大,行为问卷得分呈下降趋势,工人,知识分子,干部及其他职业行为问卷得分明显高于农民和家务劳动,化程度越高,行为问卷得分越高;业余体力活动参加行为,问卷得分较低,结论：“健康”中老年人中,行为类型特征与性别,年龄,职业,化程度和是否参加业余体力活动有关。A型行为对甘油碡酯水平,血球压积有一定影响。     

CaSO4和MgSO4晶须填料对牙科复合树脂抗弯强度的影响

Objective The aim of this study was to evaluate the effect of calcium sulphate and magnesium sulfate whiskers on the flexture strengths of dental composite resin.Methods Calcium sulfate whiskers and magnesium sulfate whiskers were prepared.Seven groups of composite resin specimens were prepared including one control group and six groups using either calcium sulfate whiskers or magnesium sulfate whiskers comprising 1%,10%,20%,30% of the material by weight.Before mixing with resin,both whiskers were surface modified by Sodium stearate.The standard resin samples with dimensions of 25 mm×2 mm×2 mm were prepared according to the ISO-10477 criterion(eight for each group),and their flexure strengths were measured by a universal testing machine.The fracture surfaces of selected specimens were examined by a scan electron microscope.Results Neither mixture improved the flexure strength of composite resin when the adding proportions of calcium sulfate and whiskers magnesium sulfate whiskers were under 10%.However,when the adding proportions were 20 wt % and 30 wt%,magnesium sulfate whiskers excerted positive effects.Concluson Appropriate proportions of magnesium sulfate crystal whisker would increase the flexure strength of dental composite resin.     

Effect of cilostazol on cerebral arteries in secondary prevention of ischemic stroke

Objective

To compare the effects of cilostazol on cerebral arteries and cerebrovascular blood flow in secondary prevention of ischemic stroke, with those of aspirin.

Methods

Sixty-eight patients who had ischemic stroke during the recent 1–6 months were recruited and randomized into cilostazol or aspirin group. Cerebrovascular condition was assessed by magnetic resonance angiography (MRA) and transcranial doppler ultrasonography (TCD) at the beginning of the study and after 12-month medication.

Results

During the clinical follow-up, ischemic stroke recurred in 2 patients in cilostazol group, while in aspirin group, one case of ischemic stroke recurrence and one case of acute myocardial infarction were found. MRA revealed that in aspirin group, the percentages of patients experiencing aggravation and attenuation of cerebrovascular condition were 3.3% and 6.7%, respectively, while in aspirin group, they were 3.3% and 10%, respectively. Moreover, TCD revealed that 26.9% of the patients in aspirin group and 14.3% of the patients in cilostazol group experienced aggravation of cerebrovascular condition. However, the systolic peak flow velocity of the previously abnormal arteries increased by 42.9% after 12-month medication of cilostazol, which was significantly higher than that after aspirin medication (27.5%) (P = 0.04). Furthermore, as a major side effect of antiplatelet therapy, the frequrency of bleeding was much less in cilostazol group (0 case in cilostazol group vs 5 in aspirin, P < 0.05).

Conclusion

Cilostazol is as effective as aspirin in preventing the aggravation of cerebral arteries in secondary prevention of ischemic stroke. Besides, it is more safe. Cilostazol can increase the systolic peak flow velocity of cerebral arteries, which may improve the blood supply of focal ischemia.
