ObjectiveTo investigate the application of rapid immunohistochemical staining technique in intraoperative frozen section diagnosis of thyroid neoplasm.Methods MaxVision one-step rapid immunohistochemical staining technique was used to detect the expression of CK19,HBME-1,and Gal-3 in frozen section of papillary thyroid carcinoma(PTC)andthyroid benign lesions.MaxVision conventional immunohistochemistry of frozen remaining tissue was served as control.ResultsMaxVision one-step rapid immunohistochemical staining technique could be completed in 20 minutes.The positive localizations of three markers detected by rapid immunohistochemistry were similar to conventional immunohistochemistry, in general.The expression of CK19 was located in cytoplasm and cellular membrane.Gal-3 and HBME-1 were mainly detected in follicular luminal border and/or surface of papilla. The staining intensity in rapid immunohistochemistry was stronger than that in conventional immunohistochemistry. The positive rates of CK19,HBME-1,and Gal-3 by rapid immunohistochemistry in frozen sections were: 0 (0/28),10.7 ％ (3/28),0 (0/28),respectively,for benign lesions (nodular goiter,Hashimoto thyroiditis,thyroid adenoma); and 94.9 ％(37/39),92.3 ％ (36/39),92.3 ％ (36/39),respectively,for PTC.The expression of three markers between thyroid benign lesions and PTC had a significant difference (x2 =59.326,55.861,44.605,all P ＜ 0.001).In benign lesions,the rate of same case with two and more positive markers was 0,while in PTC it was 100 ％ and significantly different (x2 =67.000,P ＜ 0.05).ConclusionMaxVision one-step rapid immunohistochemical staining technique could be applied in intraoperative frozen section diagnosis.Detecting CK19,HBME-1,and Gal-3 expression in intraoperative frozen section has an auxiliary value for diagnosis of PTC.

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.
