OBJECTIVETo investigate the effects of oral contraceptive pretreatment (OCP) in patients with polycystic ovarian syndrome (PCOS) undergoing controlled ovarian hyperstimulation for IVF-ET.
METHODSWe randomly divided 85 patients with P-COS undergoing IVF-ET into an OCP (n = 53) and a control group (n = 32), the former received OCP, while the latter did not before the cycle. We retrospectively analyzed the data of the patients for the ovulation promoting effect of OCP and its influence on the incidence of ovarian hyperstimulation syndrome (OHSS) and outcomes of IVF-ET.
RESULTSCompared with the control group, OCP significantly reduced the formation of ovarian cyst (P < 0.05), remarkably increased the duration of gonadotropin stimulation and consumption (P < 0.01) , and markedly raised the percentage of mature ova (87.92% vs 92.85%, P < 0.05). But no significant differences were observed between the two groups in the incidences of moderate and severe OHSS, number of retrieved oocytes, and rates of fertilization, miscarriage and clinical pregnancy.
CONCLUSIONOCP for patients with PCOS can help to control the time of ovarian stimulation, improve the synchronism of follicular development, and increase the duration of gonadotropin stimulation and consumption, but cannot change the incidences of moderate and severe OHSS.

OBJECTIVETo evaluate the clinical effects of anterior segmental decompression for the treatment of multi-segment cervical spondylotic myelopathy.
METHODSThe clinical data of 84 patients with multi-segment cervical spondylotic myelopathy treated between August 2005 to March 2016 were retrospectively analyzed. According to different operative methods the patients were divided into control group and observation group, with 42 cases in each group. In the control group, including 26 males and 16 females, the age was (56.87±11.89) years old and course of disease was(7.91±3.71) years on average, the lesion segment occurred on C₃-C₆ of 36 cases and on C₄-C₇ of 6 cases. There were 24 males and 18 females in observation group, with the mean age of (54.58±12.56) years old, and the course of disease was(8.03±3.52) years, the lesion segment occurred on C₃-C₆ of 34 cases, and on C₄-C₇ of 8 cases. The patients in control group were treated with posterior laminoplasty, and the patients in observation group underwent anterior segmental decompression. Operation time, intraoperative blood loss, hospitalization time, bone graft fusion time and complication rate were observed between two groups. JOA scores and Cobb angle of fusion segment were compared before operation and 3, 6, 9 months after operation.
RESULTSOperation time, intraoperative blood loss, hospitalization time and complication rate in observation group were significantly lower than in control group(<0.05); the bone fusion time in observation group was significantly lower than in control group(<0.01);3, 6, 9 months after surgery, JOA score and the segment Cobb angle in observation group were significantly higher than in control group(<0.01).
CONCLUSIONSAnterior segmental decompression for the treatment of multi-segment cervical spondylotic myelopathy has obvious advantages of less vertebral resection, thorough decompression, good stability, less postoperative complications, which can effectively promote the recovery of the spinal cord function and vertebral stability.
