Objective: Ethiodized poppy seed oil for hysterosalpingography (HSG) is reported to display some therapeutic effect on infertility, but big a sample-size study under real clinical settings is still lacking to verify the speculation. Thus, this real-world study enrolled 1,053 infertile patients who underwent ethiodized poppy seed oil-based HSG to explore its fertility enhancement value.

Method: A total of 1,053 infertile patients who underwent HSG using ethiodized poppy seed oil as the contrast medium were retrospectively analyzed.

In recent years, with increasing prevalence, particularly in young patients, breast cancer is considered to be one of the most common malignancies. The aim of the present study was to evaluate the clinical value of digital breast tomosynthesis (DBT) in diagnosing molecular subtypes of breast cancer. The present study retrospectively analyzed 134 cases of breast cancer with data regarding surgery, complete pathology and immunohistochemistry, which were collected at The Second Clinical College of Fujian Medical University (Quanzhou, China) between May 2013 and October 2014.

A radical-promoted cyclization of methylthiolated alkynones with diverse radical precursors has been developed. This strategy occurred via a C(sp)-S bond formation and C(sp)-S cleavage sequence and allows an efficient synthesis of a variety of phosphoryl-, sulfenyl-, CFCOOEt-, and acyl-containing thiochromone derivatives in moderate to good yields under mild conditions.

An efficient approach to tetrasubstituted alkenylboronates via a cascade borylation/B-O elimination of propynols and Bpin was disclosed. A series of tetrasubstituted alkenylboronates were readily furnished with this strategy in good yields, with further transformations leading to tetrasubstituted alkenes and β-diketones demonstrating the synthetic potential of the alkenylboronates constructed by this strategy as versatile intermediates in organic synthesis.

tert-Butyl hydroperoxide-initiated radical cyclization of 2-alkynylthioanisoles or -selenoanisoles with sulfinic acids has been developed. This reaction is applicable to a wide substrate scope via one C(sp)-S(Se) bond cleavage and two C(sp)-S(Se) bond formation, leading to the synthesis of 3-(arylsulfonyl)benzothiophenes or -benzoselenophenes under mild conditions.

To explore the effect of digital breast tomosynthesis (DBT) on the classification of breast imaging-reporting and data system (BI-RADS) and its significance.
 Methods: A total of 832 patients with breast diseases, who came from Second Clinical College of Fujian Medical University from May 2013 to November 2013, were collected. The patients were examined by double position radiography (including craniocaudol and mediolateral oblique) and COMBO mode [including DBT and full-field digital mammography (FFDM)].

Background: Full-field digital mammography (FFDM) with dense breasts has a high rate of missed diagnosis, and digital breast tomosynthesis (DBT) could reduce organization overlapping and provide more reliable images for BI-RADS classification. This study aims to explore application of COMBO (FFDM+DBT) for effect and significance of BI-RADS classification of breast cancer.

Materials And Methods: In this study, we selected 832 patients who had been treated from May 2013 to November 2013.
