Objective:To evaluate the differences in pregnancy outcomes of patients and cost variance with hormone replacement therapy for frozen-thawed embryo transfer (HRT-FET) under different luteal support scheme.Methods:A retrospective cohort study was performed. A total of 1009 cycles of HRT-FET from October 2017 to April 2019 were collected and the patients were recruited from Reproductive Hospital Affiliated to Shandong University. According to different luteal support protocol, patients in group A ( n=504) were treated with oral progesterone capsule while patients in group B ( n=505) were treated with progesterone vaginal sustained release gel and dydrogesterone. The pregnancy outcomes, pregnancy complications and cost-effectiveness ratio were compared between the two groups. Results:There were no significant differences in embryo implantation rate, clinical pregnancy rate, multiple pregnancy rate, ectopic pregnancy rate, early and late abortion rate, premature birth rate, live birth rate, incidence of pregnancy complications and birth defect rate between the two groups (all P>0.05). But the incidence of vaginal bleeding in group B was significantly higher than that in group A [6.0% (30/504) vs. 10.3% (52/505), P=0.015], cost-effectiveness ratio (C/E) in group A was better than that in group B (17.76 vs. 77.30). Conclusion:For patients undergoing HRT-FET cycles, oral progesterone capsule can reduce vaginal bleeding and medical cost, while achieving a pregnancy outcome similar to that of progesterone vaginal sustained release gel and dydrogesterone, so it can be used as a luteal support scheme in clinic.

Results:The total effective rate of the observation group was 73.17%(30/41), which was significantly higher than that of the control group[51.22%(21/41)] (χ 2=4.201, P<0.05). After treatment, the ALB, AST, ALT, TBIL levels in the control group were (36.74±4.25)g/L, (247.85±12.36)U/L, (214.57±10.14)U/L, (288.96±16.30)μmol/L, respectively, which in the observation group were (45.14±5.30)g/L, (162.65±8.30)U/L, (120.74±6.33)U/L, (241.74±15.02)μmol/L, respectively, the differences between the two groups were statistically significant( t=7.917, 36.642, 50.261, 13.641, all P<0.05). After treatment, the interferon gamma(IFN-γ), tumor necrosis factor alpha(TNF-α), interleukin 6(IL-6) levels in the control group were (318.96±92.15)ng/L, (334.74±102.58)ng/L, (65.89±6.33)ng/L, respectively, which in the observation group were (261.15±89.62)ng/L, (274.15±85.12)ng/L, (54.36±5.23)ng/L, respectively, the differences between the two groups were statistically significant( t=2.879, 2.910, 8.991, all P<0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups ( P>0.05). Conclusion:Plasma exchange in the treatment of severe hepatitis can improve the clinical therapeutic effect, improve its liver function, reduce the level of inflammatory cytokines, and has no adverse reactions.

The AIDS epidemic in men who have sex wlth men (MSM) in recent years showed a sharp upward trend, looking for behavioral intervention strategies should be imperative. Fear appeals by fear prompted intervention received intervention information, provide a new breakthrough to achieve better effect of propaganda and intervention. After over 70 years development, the Fear Appeal generated from the driver model that proposed the fear decided the effectiveness of behavior intervention, to the extended parallel process model theory which integrated protection motivation theory and parallel process theory, both of which believed the fear is just one of the estimators, suggested fear is the key factor. The fear appeal theory is turning to be even more comprehensive and accurate. As an important theoretical basement, the fear appeal is still developing, and need more work to make it perfection.
