Enabling AI-Generated Content for Gadolinium-Free Contrast-Enhanced Breast Magnetic Resonance Imaging.

Background: There is increasing interest in utilizing AI-generated content for gadolinium-free contrast-enhanced breast MRI.

Purpose: To develop a generative model for gadolinium-free contrast-enhanced breast MRI and evaluate the diagnostic utility of the generated scans.

Study Type: Retrospective.

When should endovascular gastrointestinal anastomosis transection Glissonean pedicle not be used in hepatectomy? A case report.

Background: The literature on post-hepatectomy bile duct injury (PHBDI) is limited, lacking large sample retrospective studies and high-quality experience summaries. Therefore, we reported a special case of iatrogenic bile duct injury caused by Glissonean pedicle transection with endovascular gastrointestinal anastomosis (endo-GIA) during a right hepatectomy, analyzed the causes of this injury, and summarized the experience with this patient.

Case Summary: We present the case of a 66-year-old woman with recurrent abdominal pain and cholangitis due to intrahepatic cholangiectasis (Caroli's disease).

Synthesizing the First Phase of Dynamic Sequences of Breast MRI for Enhanced Lesion Identification.

Objective: To develop a deep learning model for synthesizing the first phases of dynamic (FP-Dyn) sequences to supplement the lack of information in unenhanced breast MRI examinations.

Methods: In total, 97 patients with breast MRI images were collected as the training set (n = 45), the validation set (n = 31), and the test set (n = 21), respectively. An enhance border lifelike synthesize (EDLS) model was developed in the training set and used to synthesize the FP-Dyn images from the T1WI images in the validation set.

Rare isolated extra-hepatic bile duct injury: A case report.

Background: Extra-hepatic bile duct injury (EHBDI) is very rare among all blunt abdominal injuries. According to literature statistics, it only accounts for 3%-5% of abdominal injuries, most of which are combined injuries. Isolated EHBDI is more rare, with a special injury mechanism, clinical presentation and treatment strategy, so missed diagnosis easily occurs.

Single-cell RNA-seq reveals the diversity of trophoblast subtypes and patterns of differentiation in the human placenta.

The placenta is crucial for a successful pregnancy and the health of both the fetus and the pregnant woman. However, how the human trophoblast lineage is regulated, including the categorization of the placental cell subtypes is poorly understood. Here we performed single-cell RNA sequencing (RNA-seq) on sorted placental cells from first- and second-trimester human placentas.

PLAC8, a new marker for human interstitial extravillous trophoblast cells, promotes their invasion and migration.

Proper differentiation of trophoblast cells in the human placenta is a prerequisite for a successful pregnancy, and dysregulation of this process may lead to malignant pregnancy outcomes, such as preeclampsia. Finding specific markers for different types of trophoblast cells is essential for understanding trophoblast differentiation. Here, we report that placenta-specific protein 8 (PLAC8) is specifically expressed in the interstitial extravillous trophoblast cells (iEVTs) on the fetomaternal interface.

Live cell imaging of in vitro human trophoblast syncytialization.

Human trophoblast syncytialization, a process of cell-cell fusion, is one of the most important yet least understood events during placental development. Investigating the fusion process in a placenta in vivo is very challenging given the complexity of this process. Application of primary cultured cytotrophoblast cells isolated from term placentas and BeWo cells derived from human choriocarcinoma formulates a biphasic strategy to achieve the mechanism of trophoblast cell fusion, as the former can spontaneously fuse to form the multinucleated syncytium and the latter is capable of fusing under the treatment of forskolin (FSK).

[Application of proteomic models for the diagnosis of inflammatory and non-inflammatory preterm delivery].

Objective: To establish the serum proteomic models for the identification of premature delivery with inflammation or non-inflammation.

Methods: The laboring patients from 2008 to 2010 at our hospital were divided into 5 groups according to placental pathology, including inflammatory preterm group, non-inflammatory preterm group and blind test group (n = 50 each). The control group was normal full-term.

[Analysis of related factors of premature delivery for the migrant population in local suburban Beijing areas].

Objective: To study the health conditions of pregnant migrant women in some suburban areas of Beijing by comparing a variety of pathological, physiological and social factors and exploring the relevant factors associated with preterm birth so as to prevent effectively preterm birth.

Methods: A total of 279 cases of pregnancy in preterm birth at out hospital from January 2004 to December 2008 were reviewed. The date of maternal age, parity, prenatal examinations, history of vaginitis, history of chorioamnionitis, premature rupture of membranes, occupation, residing location and education status were recorded.

[Study of factors associated with subclinical chorioamnionitis in term pregnancy].

Objective: To investigate the effects of various factors upon subclinical chorioamnionitis (SCCAS) during pregnancy and delivery.

Methods: A total of 796 cases of pregnancy in full-term birth at our hospital from December 2006 to December 2008 were reviewed. The data of maternal age, gravidity, parity, gestational age, prenatal care, history of vaginitis, premature rupture of membranes, occupation, educational status and delivery mode were recorded.

[Expression and its clinical significance of p27 protein in cervical carcinoma tissues].

Aim: To investigate the expression of p27 protein and its significance in cervical carcinoma tissues.

Methods: The p27 protein expression in 26 normal cervical tissues and 48 cervical carcinoma tissues was detected by streptavidin-peroxidase staining(SP method).

Results: The positive rate of p27 protein expression in 48 cervical carcinoma tissues was 39.
