Results:The etiologic mechanism of steroid-induced necrosis of femoral head is:Disorder of lipometabolism;increasing of intraosseous pressure;Osteoporosis and poisonous action;vasculitis,coagulation before steroid administration and intravascular coagulation.

结果：激素性股骨头缺血坏死存在如下发病机理：脂肪代谢紊乱；骨内压增加；骨质疏松及激素的毒性作用；血管炎、前凝血状况及血管内凝血。

Thirty patients with acute promyelocytic leukemia were observed between September 1977 and October 1985. Bleeding diathesis with petechiae or ecchymosis (80%) was the most common presenting symptom. Seventeen of 24 patients with pretreated coagulation studies were diagnosed to have disseminated intravascular coagulation. Six out of 11 patients died from intracranial hemorrhage after a mean of 2.5 days of hospitalization without any treatment. DIC was responsible for death in most cases. Induction therapy with anthracycline and cytosine arabinoside combined with prophylactic heparin infusion was carried out in the remaining 19 patients. Two patients were incompletely treated. Eight out of 17 patients achieved complete remission after a mean of 63 days following chemotherapy. The remission rate was 47%.

自1977年9月至1985年10月，观察30位急性前骨髓球性白血病病帣，临床上诊断时初发症状，主要为出血现象，尤其以瘀斑出血最多，占80%。24位病人作治疗前凝血机能检查，17位出现播散性血管内凝固症候群。11位病人没有接受治疗，其中6位经诊断后平均2.5天内死於脑内出血，凝血机能检验显示5位有播散性血管内凝固症候群。19位病人接受anthracycline与ara-C并用预防性肝素静脉滴注作缓解诱导治疗，2位不完全治疗，其余17位中有8位经过平均63天之化学治疗得到完全缓解，缓解率47%。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
