Clinical data of 5217 patients who underwent IVF-ET were retrospectively analyzed. Patients were divided into the long-acting GnRH-a group (n=1330) and the short-acting GnRH-a group (w=3887) based on their various treatment plans. The clinical and laboratory embryo data and clinical pregnancy outcomes were compared between the two groups. The results showed that there were no significant differences in the age, infertility, primary/secondary infertility rate, IVF rate, body mass index (BMI), antral follicle counting (AFC), folliclestimulating hormone (FSH) level, and the number of transplanted embryos between the two groups (P>0.05). There were no significant differences in the oocyte numbers, M II rate, fertilization rate, cleavage rate and blastocyst formation rate (P>0.05) between the two groups. The gonadotropin (Gn) using days, Gn dose and endometrial thickness were significantly greater in the long-acting GnRH-a group than those in the short-acting GnRH-a group (P<0.01). Additionally, the estradiol (E2) levels, blastocyst freezing rate, embryo utilization rate, transplant cancellation rate and abortion rate were significantly lower in the long-acting GnRH-a group than those in the shortacting GnRH-a group (P<0.01). The clinical pregnancy rate and embryo implantation rate were significantly higher in the long-acting GnRH-a group than in the short-acting GnRH-a group (P<O.Ol). It was concluded that use of long-acting GnRH-a can effectively reduce the transplant cancellation rate and improve the clinical pregnancy rate of the fresh cycle.展开更多

Methods: Sixty-three consecutive men (between 58 - 86 years of age) requiring CAB for prostate cancer were enrolled in the study. Patients with diabetes mellitus, an additional malignancy, coronary heart disease, atrial fibrillation, heart failure or a medical history of cardiac event in the last 12 months were excluded from the study. Additionally, those who were taking medicine affecting heart rate were excluded. The participants were divided into two groups according to their modality of castration. The first group consisted of 35 patients who received bilateral orchiectomy plus anti-androgen medication. The second group contained 28 patients who accepted gonadotropin-releasing hormone (GnRH) plus anti-androgen therapy. After complete examinations and biochemical tests, the ECG leads of the patients were obtained conveniently. This was then repeated at three- and six-month visits. ECG findings (including heart rate, PR, QRS, QT, corrected QT (QTc) intervals and QT dispersion (QTd)) were recorded and analysed statistically. The groups were then compared in terms of pre- and post-treatment ECG outcomes. Results: Both groups revealed similarly lower heart rate and prolonged PR, QRS, QT, corrected QTc and QTd by the end of six months. By the end of three months, all variables had changed significantly in the orchiectomy group, whereas in the GnRH group, they had not. Conclusion: CAB may result in lower heart rate and prolonged QT, a condition associated with fatal cardiac arrhythmia and sudden death. Therefore, patients receiving CAB should be monitored closely for cardiac adverse effects.展开更多

Methods: Patients who were diagnosed with endometriosis in Bazhong Hospital of Traditional Chinese Medicine between November 2014 and March 2017 were selected as the research subjects and randomly divided into two groups, observation group received preoperative Guizhi Fuling Pill combined with GnRH analog therapy, and control group received preoperative GnRH analog monotherapy. After surgical resection, the endometriosis lesion was collected to determine the mRNA expression of proliferation and invasion-related genes as well as the protein expression of MEK/ERK pathway molecules. Results: Id-1, Sema3A, c-IAP1, OPN and uPA mRNA expression as well as p-MEK, p-EKR1/2, caspase-3 and MMP2 protein expression in endometriosis lesion of observation group were significantly lower than those of control group while Bak, Smac, PAI-1, TIMP1 and TIMP2 mRNA expression as well as caspase-3 protein expression were significantly higher than those of control group. Conclusion: Guizhi Fuling Pill combined with GnRH analog can inhibit the cell proliferation and invasion as well as the MEK/ERK pathway activation in endometriosis lesions.展开更多
