Early differential diagnosis of cystic biliary atresia and choledochal cyst in the fetus: A multicenter retrospective study.

J Hepatobiliary Pancreat Sci

January 2025

Department of Neonatal Surgery, Guangzhou Women and Children's Medical Center, Guangzhou Medical University, Guangzhou, Guangdong, China.

Background/purpose: Fetal hilar cyst is primarily diagnosed as two diseases after birth, cystic biliary atresia (CBA) and choledochal cyst (CC). The aim of our study was to explore more reliable indicators in early differential diagnosis of these cysts.

Methods: We recruited a total of 50 cases with a prenatal diagnosis of hepatic cyst at three centers, and patients were divided into a CBA group (n = 16) and CC group (n = 34) according to postnatal intraoperative diagnosis.

Department of Obstetrics and Gynecology, Beijing Key Laboratory of Reproductive Endocrinology and Assisted Reproductive Technology and Key Laboratory of Assisted Reproduction, Ministry of Education, Center for Reproductive Medicine, Peking University Third Hospital, Beijing 100191, China.

Parthenogenetic embryos derive their genomes entirely from the maternal genome and lack paternal imprint patterns. Many achievements have been made in the study of genomic imprinting using human parthenogenetic embryonic stem cells (hPg-ESCs). However, due to developmental defects and ethical limits, a comprehensive understanding of parthenogenetic embryonic development is still lacking.

Guangdong Provincial Key Laboratory of Construction and Detection in Tissue Engineering, School of Basic Medical Science, Southern Medical University, Guangzhou, Guangdong Province, China.

Cardiovascular diseases are a leading cause of death worldwide, and effective treatment for cardiac disease has been a research focal point. Although the development of new drugs and strategies has never ceased, the existing drug development process relies primarily on rodent models such as mice, which have significant shortcomings in predicting human responses. Therefore, human-based in vitro cardiac tissue models are considered to simulate physiological and functional characteristics more effectively, advancing disease treatment and drug development.

Department of Emergency Medicine, Biomedical Innovation Center, The Sixth Affiliated Hospital, Sun Yat-sen University, Guangzhou 510655, Guangdong Province, China.

Background: Hepatobiliary stone disease involves an intrahepatic bile duct stone that occurs above the confluence of the right and left hepatic ducts. One-step percutaneous transhepatic cholangioscopic lithotripsy (PTCSL) using the percutaneous transhepatic one-step biliary fistulation (PTOBF) technique enables the clearing of intrahepatic stones and the resolution of strictures. However, hepatolithiasis with associated strictures still has high residual and recurrence rates after one-step PTCSL.

Background: Long non-coding ribonucleic acids (lncRNAs) regulate messenger RNA (mRNA) expression and influence cancer development and progression. Cuproptosis, a newly discovered form of cell death, plays an important role in cancer. Nonetheless, additional research investigating the association between cuproptosis-related lncRNAs and prostate cancer (PCa) prognosis is required.

AKG/OXGR1 promotes skeletal muscle blood flow and metabolism by relaxing vascular smooth muscle.

In response to contraction during exercise, skeletal muscle growth and metabolism are dynamically regulated by nerve action, blood flow, and metabolic feedback. -Ketoglutarate (AKG), a bioactive intermediate in the tricarboxylic acid cycle released during exercise, has been shown to promote skeletal muscle hypertrophy. However, the underlying mechanism of AKG in regulating skeletal muscle development and metabolism is still less known.

Background: Myocardial ischemia/reperfusion (I/R) injury significantly impacts the recovery of ischemic heart disease patients. Non-coding RNAs, including miRNAs, have been increasingly recognized for their roles in regulating cardiomyocyte responses to hypoxia/reoxygenation (H/R) injury. miR-181c-5p, in particular, has been implicated in inflammatory and apoptotic processes, suggesting its potential involvement in exacerbating cellular damage.

The high mortality rate from hepatocellular carcinoma (HCC) is due primarily to challenges in early diagnosis and the development of drug resistance in advanced stages. Many first-line chemotherapeutic drugs induce ferroptosis, a form of programmed cell death dependent on ferrous iron-mediated oxidative stress, suggesting that drug resistance and ensuing tumor progression may in part stem from reduced ferroptosis. Since circular RNAs (circRNAs) have been shown to influence tumor development, we examined whether specific circRNAs may regulate drug-induced ferroptosis in HCC.

Crosstalk between GLTSCR1-deficient endothelial cells and tumour cells promotes colorectal cancer development by activating the Notch pathway.

Cell Death Differ

January 2025

Department of Pathology and International Institutes of Medicine, The Fourth Affiliated Hospital (Yiwu), Zhejiang University School of Medicine, Hangzhou, 310058, China.

Cancer stem cells (CSCs) typically reside in perivascular niches, but whether endothelial cells of blood vessels influence the stemness of cancer cells remains poorly understood. This study revealed that endothelial cell-specific GLTSCR1 deletion promotes colorectal cancer (CRC) tumorigenesis and metastasis by increasing cancer cell stemness. Mechanistically, knocking down GLTSCR1 induces the transformation of endothelial cells into tip cells by regulating the expression of Neuropilin-1 (NRP1), thereby increasing the direct contact and interaction between endothelial cells and tumour cells.

The combined impact of concurrent primary Sjögren's syndrome (pSS) and autoimmune thyroid disease (AITD) on pregnancy outcomes remains underreported. A retrospective analysis was conducted on 115 pregnant patients diagnosed with pSS and delivering at the Third Affiliated Hospital of Guangzhou Medical University from January 2009 to July 2023. The effects of AITD on maternal and neonatal outcomes were examined and compared to a control group without AITD.

Pulmonary sarcomatoid carcinoma (PSC) is a rare non-small-cell lung cancer with sarcomatous components or sarcomatoid differentiation, high degree of malignancy, and insensitivity to chemotherapy or radiotherapy. The management of PSC coexisting with tuberculosis (TB) poses a greater challenge, as it necessitates concurrent administration of both anti-TB and anti-neoplastic therapies. The efficacy of anti-PD-1 immunotherapy in non-small-cell lung cancer is promising, but its safety in patients with co-existent TB remains uncertain.

Department of Obstetrics and Gynecology, The Third Affiliated Hospital, Guangzhou Medical University, Guangzhou 510150, China.

Studies have shown that circRNAs play an important regulatory role in trophoblast function and embryonic development. Based on sequencing and functional experiments, we found that hsa_circ_0069443 can regulate the function of trophoblast cells, and its presence is found in the exosomes secreted by trophoblast cells. It is known that exosomes mediate the interaction between the uterus and embryo, which is crucial for successful pregnancy.
