ATP-binding cassette transporter A1 (ABCA1) and scavenger receptor class B type I (SR-BI/CLA-1) are the key proteins in reverse cholesterol transport (RCT). The high expression of ABCA1 and SR-BI/CLA-1 can decrease the danger of atherosclerosis. The purpose of the study is to find ABCA1 and CLA-1up-regulators for treating atherosclerosis by using cell-based high throughput screening models. Among 20 000 compounds screened, E0869 [1-(3, 4-dimethylphenyl)-1-oxopropan-2-yll4-((methylsulfonyl)methyl)benzoate] was found as the positive hit. The up-regulated activities of E0869 in ABCAl1-LUC and bCA-l1-LUC HepG2 cell were 160% and 175%, respectively. The EC50 values of E0869 in ABCAl1-LUC and CLA-l1-LUC HepG2 cell were 3.79 and 1.42 pμol- x ,(-1) respectively. E0869 could upregulate the mRNA and protein levels of ABCA1, SR-BI/CLA-1 and ABCGJ1genes in HepG2 and RAW264.7 cells by Real-Time Quantitative PCR and Western blotting analysis, but could not influence the expression of FAS, SREBP-l1 and CD36. Foam cell assay showed that E0869 could inhibit lipids accumulation in mouse peritoneal macrophages RAW264.7. Cholesterol efflux assay showed that E0869 could induce HDL-mediated cholesterol efflux in mouse peritoneal macrophages RAW264.7. In conclusion, E0869 could up-regulate ABCA1 and CLA-1 activity, and had good anti-atherosclerotic activity in vitro.

OBJECTIVETo explore effective pretreated methods for hydrosalpinx before frozen embryo transfer (FET).

METHODSA randomized controlled study was performed on 229 FET cycles of hydrosalpinx patients. They were assigned to two groups by random digit table, Group A (94 cases), Group B (89 cases), and Group C (46 cases). Patients in Group A received transvaginal aspiration of hydrosalpinx combined with auricular point sticking. Those in Group B received transvaginal aspiration of hydrosalpinx group. Those in Group C received no transvaginal aspiration of hydrosalpinx. Pregnancy outcomes of FET, endometrial and subendometrial blood flow distribution on the embryo transfer day were compared among the three groups.

RESULTSThere was no statistical difference in the endometrial thickness on FET day, the number of transfer embryos, the number of transferred good quality embryos among the three groups (P > 0.05). The clinical pregnancy rate and the embryo implantation rate were significantly higher in Group A than in Group C (P < 0.05), and the clinical pregnancy rate was significantly higher in Group A than in Group B (P < 0.05). The early abortion rate and the transfer cycle cancel rate were significantly lower in Group A than in Group C (P < 0.05). Type A endometrial and subendometrial blood flow distribution was dominant in Group A, which was significantly higher in Group A than the rest two groups (P < 0.05). Type A distribution rate was also significantly higher in Group B than in Group C (P < 0.05).

CONCLUSIONTransvaginal aspiration of hydrosalpinx combined with auricular point sticking before FET could improve the endometrial receptivity and improve outcomes of IVF.
