Objective To explore the normal reference range of fetal gallbladder in 28 to 35 weeks of pregnancy under magnetic resonance imaging characteristics, observe and explore the growth and development of fetal gallbladder, and provide a new detection method for evaluating fetal growth and development for prenatal examination. Methods One hundred single pregnant women who had underwent fetal abdominal magnetic resonance imaging from June 2017 to May 2018 in Dalian Municipal Women and Children′s Medical Center were selected. The pregnant women were divided into 2 groups according to the gestational weeks: group A (pregnancy 28 to 31 weeks, 64 cases) and group B (pregnancy 32 to 35 weeks, 36 cases). The length, width and transverse diameter of fetal gallbladder were measured by magnetic resonance, and the gallbladder volume was calculated. Results In group A, magnetic resonance result showed that 1 case had no gallbladder and 1 case had double gallbladder, but the fetal gallbladders of these 2 cases were normal after birth. The display rate of fetal gallbladder in group A was 98.4% (63/64), and that in group B was 100.0% (36/36); the abnormal rate in group A was 3.1% (2/64), and that in group B was 0. The length, width, transverse diameter and volume of gallbladder in group B were significantly higher than those in group A: (16.5 ± 6.0) mm vs. (13.2 ± 4.2) mm, (6.5 ± 3.5) mm vs. (5.2 ± 1.1) mm, (6.8 ± 2.6) mm vs. (6.4 ± 3.4) mm and (373.3 ± 284.1) mm3 vs. (258.5 ± 232.4) mm3, and there were statistical differences (P＜0.05). Conclusions Fetal magnetic resonance during lategestation has the new means of prenatal evaluation of fetal growth and development, which has clinical application value.

Organ transplantation is an effective treatment for end-stage organ failure. However, organ shortage has always been a common problem faced by countries around the world. The recognition and active participation of intensive care unit (ICU) medical staff in organ donation contributes to promoting the development of organ donation, thereby alleviating the shortage of donor organ. In this article, the key strategies of ICU donor management to promote organ donation and the key strategies of ICU medical staff management to promote organ donation were summarized, aiming to provide reference for organ donation practitioners (especially ICU medical staff) and jointly facilitate the professional development of organ donation.
