ABSTRACT
OBJECTIVE: To explore the effect of domestic recombinant follicle stimulating hormone(rFSH)in the course of controlled ovarian hyperstimulation using long protocol in patients with different ovarian reserve functions.METHODS: A retrospective cohort study was made on 1284 patients who were treated with in vitro fertilization/intracytoplasmic sperm injection-embryo transfer with standard long protocol for ovulation induction from January 2016 to January 2018 in Reproductive Medicine Center,Yuhuangding Hospital of Yantai. According to their AMH level,they were divided into normal ovarian reserve group(AMH:1.2-4.5μg/L,678 patients)and high response group(AMH>4.5μg/L,606 patients).Each group was divided into domestic rFSH subgroup(Jinsaiheng)(340 patients in normal ovarian reserve group,330 patients in high response group)and imported rFSH subgroup(338 patients in normal ovarian reserve group,276 patients in high response group)according to the different use of gonadotrophin on the start-up day.The clinical and laboratory indexes of the two subgroups were compared under different ovarian reserve functions.RESULTS: Regardless of normal or high ovarian reserve function,there was no significant difference in Gn dosage[(1983.15±510.00)U vs.(1913.32±422.12)U,P=0.053;(1816.86±506.37)U vs.(1786.63±453.90)U,P=0.44],days of Gn[(8.96±1.33)days vs.(8.87±1.24)days,P=0.36;(9.45±1.51)days vs.(9.44±1.47)days,P=0.91],dosage of Hermetic[(144.20±67.39)U vs.(143.42±56.73)U,P=0.86;(149.52±62.38)U vs.(160.21±84.87)U,P=0.09],number of eggs obtained(8.14±3.57 vs.8.44±3.37,P=0.25;11.47±4.74 vs.11.66±4.49,P=0.62),MⅡoocyte rate(82.08% vs. 82.01%,P=0.96;82.78% vs. 82.94%,P=0.90),fertilization rate(82.17% vs. 80.98%,P=0.30;80.75% vs. 82.16%,P=0.33),cleavage rate(94.55% vs. 93.91%,P=0.52;94.12% vs. 94.84%,P=0.49),blastocyst formation rate(58.43% vs. 59.55%,P=0.69;61.14% vs. 63.09%,P=0.46),clinical pregnancy rate(59.49% vs. 56.54%,P=0.54;62.84% vs.58.70%,P=0.57),early abortion rate(7.36% vs. 6.80%,P=0.42;11.30% vs. 11.11%,P=0.93)or the incidence of moderate to severe ovarian hyperstimulation syndrome(OHSS)(3.53% vs. 4.73%,P=0.71;7.58% vs. 9.06%,P=0.53)between the two subgroups.However,the daily LH level of HCG in domestic rFSH group was significantly higher than that in imported rFSH group[(2.83±1.31)U/L vs.(2.49±1.14)U/L,P=0.007;(2.35±1.10)U/L vs.(2.11±0.94)U/L,P=0.005].In the normal ovarian reserve group,the daily E2 concentration of HCG and the number of follicles above 1.6 cm in the domestic rFSH group were lower,but the rate of good quality embryos was significantly higher(67.23% vs. 62.51%,P=0.038),the difference being statistically significant(P=0.038).CONCLUSION: Domestic rFSH has the same clinical pregnancy outcome as imported rFSH after ovulation induction,but domestic rFSH has higher LH concentration on hCG day after ovulation induction,and patients with normal ovarian reserve have higher good quality embyro rate after using domestic rFSH.
ABSTRACT
OBJECTIVE@#To study the effects of PDGF-Rb antagonists imatinib on endometrial injury repairing in the mouse model.@*METHODS@#The cultured MSCs cells from male mice were marked with BrdU in vitro, and then transplanted to the female mice which suffered from radiation injury through tail vein, PDGF-Rb antagonists imatinib was injected through abdominal cavity. Four groups were arranged, which were radiation transplantation group, normal control group, imatinib intervention group and radiation control group. BrdU incorporation, SRY expression and MVD status were detected in uterus of mice.@*RESULTS@#SRY gene was negative expressed in normal control group and radiation control group. SRY gene presented positive in radiation transplantation group and imatinib intervention group; BrdU incorporation showed negative in radiation control group and normal control group which died in the early stage in mice; the incorporation of BrdU was higher in radiation transplantation group compared with imatinib intervention group; CD34 was positive on the uterus of all the four groups, which showed highest in radiation control group and lowest in radiation control group; The MVD in imatinib intervention group was lower than radiation control group; the difference of MVD was significantly compared with normal control group (P < 0.05).@*CONCLUSIONS@#PDGF-Rb antagonists imatinib could inhibit the repairing function of MSCs in the endometrial lesions in mice.

ABSTRACT
<p><b>OBJECTIVE</b>To study the clinical efficacy of Chinese herbal retention enema combined with intrauterine douching for patients with endometritis diagnosed by hysteroscopy. They failed in in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI)-embryo transfer (ET) treatment.</p><p><b>METHODS</b>131 patients received hysteroscopy after they failed in routine IVF/ICSI-ET treatment. Of them, 66 patients diagnosed as endometritis were enrolled as the test group and 65 patients without endometritis were enrolled as the control group. Chinese herbal retention enema combined with intrauterine douching was performed on patients in the test group before the next IVF/ICSI, while direct IVF/ICSI was performed on those in the control group. The embryo implantation rate and the clinical pregnancy rate were compared between the two groups.</p><p><b>RESULTS</b>The clinical pregnancy rate and the embryo implantation rate were 48.5% and 24.2% respectively, while they were 29.2% and 14.9% respectively in the control group, showing significant difference (P < 0.05).</p><p><b>CONCLUSION</b>Chinese herbal retention enema combined with intrauterine douching could improve the embryo implantation rate and the clinical pregnancy in patients with endometritis.</p>
