Univariate analysis revealed that a high incidence of early epileptic seizures after intracerebral hemorrhage ocurred in patients with cortical hemorrhage, the medical history of intracerebral hemorrhage, electrolyte disbalance. Logistic regression analysis revealed that the position of hemorrhage and times of hemorrhage and electrolytic states were positively correlated with the incidence of early epileptic seizures after intracerebral hemorrhage. The cortical hemorrhage was the independent risk factor for the early epileptic seizures after intracerebral hemorrhage.

单因素分析显示，皮质出血、再发脑出血、电解质紊乱者易发生脑出血后早发性癫痫发作；Logistic回归分析显示，出血部位、出血次数和电解质情况与脑出血后早发性癫痫发作的发生有关，其中皮质出血为与脑出血后早发性癫痫发作有关的独立危险因素。

分析总结了红霉素分子修饰与核磁共振化学位移变化之间的关系，并且发现大环上H-3硅烷化后由高场移至低场（△δ为0.2），甲基化后又由低场移至高场（△δ为-0.4），变化均较大；而且一旦甲基化后H-3化学位移在高场几乎不再变化。

As can be seen, the beneficiary could have drawn the 10 percent installment against invoice and draft only immediately after the bill of lading was issued, but the beneficiary and we agreed that the beneficiary should not take advantage of the situation, as we had no doubt that what the drafter of the credit meant by "within 7 months after the B/L date" was "7 months after the B/L date".

可以看出，受益人可以在提单出具后立即凭发票和汇票支取那部分10%的款项。但是受益人和我方都认为受益人不应当利用这种情况，因为我们对信用证起草者的意图毫不怀疑，"提单日后7个月内"是"提单日后的7个月后"的意思。
