This paper is composed of three chapters, which respectively discusses the following impulsive delay difference equations with discrete variables and continuous variables:In chapter 1, we investigate the oscillation and nonoscillation of equation and some sufficient conditions for oscillation and nonoscillation are obtained. Consequently we extend these results to the difference equations with several delays and with nonlinear impulsive perturbations and with variable delays respectively.

Methods: A retrospective study was performed including 397 women treated with IVF-ET with unilateral/bilateral salpingectomy or salpingoplasty for ectopic pregnancy or salpingemphraxis and patients with tubal infertility with existing salpinx. A total of 116 women with history of unilateral (n=70, group A) or bilateral (n=46, group B) received salpingectomy; 60 women with history of unilateral (n=27, group C) or bilateral (n=33, group D) receivedv salpingoplasty. While the remaining women, who were accomplished in the same duration, with fallopian tube obstruction but without hydrosalpinges were acted as control group (n=221, group E). The basic clinical information and ovarian response to gonadotropins were evaluated in these groups.
