The purpose of this study is compare IVF cycle outcome in poor responders between clomiphene citrate (CC) stimulated and controlled ovarian hyperstimulation (COH) protocol. A total of 94 patients responding poorly in previous IVF cycles (estradiol<600 pg/ml or less than 3 oocytes retrieved) subsequently underwent either COH (COH group: 122 cycles, 68 patients) or CC-stimulated cycles (CC group: 43 cycles, 26 patients). CC was administered for five consecutive days starting on cycle day 3 at a dose of 100 mg daily. Serial transvaginal ultrasound examination was done from cycle day 8. Urine was collected 3~4 times before hCG injection for the detection of LH surge. The hCG was administered when serum estradiol reached greater than 150 Pg/ml and mean follicle diameter>16 mm. In COH group, ovarian stimulation was done using short protocol (GnRH-a/FSH/HMG/hCG). No difference in age or number of transferred embryos was found between CC group and COH group. COH group had significantly (p<0.05) higher mean peak level of E2 (810+/-112 vs 412+/-55 pg/ml) and greater number of retrieved oocytes (3.0+/-0.2 vs 2.0+/-0.2) than CC group. CC group had significantly embryos (1.8+/-0.2) compared with (2.1+/-0.2) in COH group. However, CC group had higher pregnancy rate than COH group per retrieval [26.9% (7/26) vs 6.2% (6/97)], or per transfer [31.8% (7/22) vs 7% (6/86)]. Although cycle cancellation rate in CC group (48.8%) was higher than that of COH group (21.3%), the pregnancy rate per cycle in CC group was still higher (16.3%) than COH group (4.9%). In addition, implantation rate in CC group was 17.5% (7/40), which was significantly p<0.01) higher than 3.9% (7/180) in COH group. These data suggest that oocyte and embryo quality are lower in COH cycles of poor responders than CC cycles. We suggest that clomiphene citrate stimulated IVF cycle may be more efficient than COH IVF cycle in poor responders in terms of lower costs and higher pregnancy performance.

Objective To detect content of 4-hydroxy-3-methoxy benzoic acid by RP-HPLC and observe the inhibitory effect of phloroglucinol on catecholamine-O-methyl transferase (COMT). Methods This study used the principle of 3,4-dihydroxy benzoic acid transforming to 4-hydroxy-3-methoxy benzoic acid under COMT’ s catalytic action. COMT (20 μL) was extracted from mouse liver homogenate. In a reaction system,10 μL catecol (1í10-3 mol·L-1 ) and 10 μL phloroglucinol (5í10-3 , 1í10-3 and 2í10-4 mol·L-1 ,respectively) were added. Products were determined by RP-HPLC to analyze effects of 4-hydroxy-3-methoxy benzoic acid on COMT. Results Phloroglucinol had inhibitory effect on COMT activity at concentrations of 5í10-3 mol·L-1 ,1í10-3 mol·L-1 and 2 í10-4 mol ·L-1 ,with the inhibition rate being 25. 3% ,17. 6% and 8. 9% ,respectively. Conclusion Phloroglucinol has an inhibitory effect on COMT activity,which is weaker than the effect of catechol of the same concentration.

Objective To determine ferulate acid in the compound angelica scinensis particle by RP-HPLC method.Methods The liquid chromatography was carried out using Zorbax C_ 18 (5?m,4.6mm?250mm),with detection wavelength at 320nm.The flow rate of mobile phase[5% acetic acid-methanol(75∶25)] was 1ml/min.Results The calibration curve was linear in the range of 0.0141~0.450mg/ml(r=0.9997,n=5).The average recoveries was 94.87%(RSD=0.5%).Conclusion The method establishied in this paper can be adopt for the compound angelica scinensis particle.This method is simple,accurate,reliable and reproducible.

Three cases of successful pregnancy outcome after intensive care in the patients with rare mullerian anomaly of complete uterine septum, hypoplastic cervical duplication and longitudinal vaginal septum in infertility clinic are reported. These presented three cases are the reports of supporting the embryologic hypothesis of bidirectional mullerian development which fusion and resorption begins at the isthmus and proceeds simultaneously in both the cranial and caudal directions rather than the classical views of unidirectional(caudal to cranial) mullerian development. Thus, we present here three cases of rare mullerian anomaly and their pregnancy outcomes in an attempt to alert gynecologist to the possible occurrence of such a malformation. In 2 cases, successful pregnancy outcomes were achieved after abdominal or hysteroscopic uterine septotomy before pregnancy and in the last case, successful pregnancy outcome intensive obstetric care was achieved even under uncorrected uterine anomaly and complete removal of uterine septum resulted in uneventful postoperative courses at the same time of cesarean section.
