RESUMEN
Systemic therapies-based combination treatments have been developed rapidly in patients with advanced hepatocellular carcinoma (HCC). However, there are still a few patients not applicable to any recommended therapies, making it considerable to try new therapeutic options. Among them, anlotinib, a new oral tyrosine kinase inhibitor, is being widely used for many advanced malignancies. We present the first case of the antitumor effect of complete remission by anlotinib combined with an anti-programmed cell death protein 1 antibody, sintilimab, in a patient with advanced HCC. In April 2020, a 51-year-old male patient was diagnosed with large HCC and underwent hepatectomy with R0 resection. Two months later, he was admitted to our hospital because of a tumor relapse with multiple liver and lung metastases. After the failure of comprehensive treatment containing sorafenib, camrelizumab and transhepatic arterial chemotherapy and embolization, 2 months after tumor relapse, the patient started to receive anlotinib and sintilimab. The multiple tumor nodules were remarkable repressed both in the liver and lung. Six months after anlotinib plus sintilimab treatment, there were no residual tumors, and the alpha-fetoprotein level was decreased from 2310.9â mg/L to normal. Also, the patient continued to receive anlotinib to date. In subsequent follow-up visits until now, there was no sign of recurrence found on imaging. Anlotinib is a promising alternative for patients insensitive to the first-line targeted drugs. More clinical studies should be conducted to further broaden the clinical indications of anlotinib and immunotherapy in patients with HCC.

Abnormal functions of trophoblast cells are associated with the pathogenesis of preeclampsia (PE). Nuclear receptor subfamily 2 group F member 1 (NR2F1) acts as a transcriptionally regulator in many diseases, but its role in PE remains unknown. Hypoxia/reoxygenation (H/R)-stimulated HTR-8/SVneo cells were used to mimic PE injury in vitro. NR2F1 overexpression alleviated trophoblast apoptosis, as evidenced by the decreased number of TUNEL-positive cells and the downregulation of caspase 3 and caspase 9 expression in cells. NR2F1 overexpression increased the invasion and migration ability of HTR-8/SVneo cells, accompanied by increased protein levels of matrix metalloproteinase (MMP)-2 and MMP-9. mRNA-seq was applied to explore the underlying mechanism of NR2F1, identifying growth differentiation factor 15 (GDF15) as the possible downstream effector. Dual-luciferase reporter, ChIP-qPCR, and DNA pull-down assays confirmed that NR2F1 bound to the promoter of GDF15 and transcriptionally inhibited its expression. GDF15 overexpression increased apoptosis and decreased the ability of invasion and migration in HTR-8/SVneo cells expressing NR2F1. MAPK pathway was involved in the regulation of PE. Administration of p38 inhibitor, ERK inhibitor, and JNK inhibitor reversed the effect of simultaneous overexpression NR2F1 and GDF15 on trophoblast apoptosis, invasion, and migration. Our findings demonstrated that NR2F1 overexpression inhibited trophoblast apoptosis and promoted trophoblast invasion and migration. NR2F1 might negatively regulate GDF15 expression by binding to its promoter region, which further inhibited MAPK signaling pathway in PE. Our study highlights that NR2F1 might sever as a potential target in PE.
RESUMEN
To assist clinicians in formulating treatment strategies for endometrial cancer (EC), this retrospective study explores the relationship between tumor volume and clinical pathological features, as well as prognosis, in patients undergoing staging surgery. Preoperative pelvic MRI examinations were conducted on 234 histologically confirmed EC patients. The ITK-SNAP software was employed to manually delineate the region of interest in the MRI images and calculate the tumor volume (MRI-TV). The analysis focused on investigating the relationship between MRI-TV and the clinical pathological features and prognosis of EC patients. Larger MRI-TV was found to be associated with various adverse prognostic factors (G3, deep myometrial invasion, cervical stromal invasion, lymphovascular space invasion, lymph node metastasis, advanced international federation of gynecology and obstetrics staging, and receipt of adjuvant therapy). The receiver operating characteristic curve indicated that MRI-TV ≥ 8 cm3 predicted deep myometrial invasion, and MRI-TV ≥ 12 cm3 predicted lymph node metastasis. Penalized spline (P-spline) regression analysis identified 14 cm3 of MRI-TV as the optimal prognostic cutoff value. MRI-TV ≥ 14 cm3 was an independent prognostic factor for overall survival and disease-free survival. For patients with MRI-TV ≥ 14 cm3, the disease-free survival rate with adjuvant therapy was superior to that of the sole staging surgery group. This study demonstrates a significant correlation between MRI-TV and clinical pathological features and prognosis in EC. For patients with MRI-TV ≥ 14 cm3, staging surgery followed by adjuvant therapy was superior to sole staging surgery.
