SARS‐CoV‐2 infection as cause of in‐utero fetal death: regional multicenter cohort study

Ultrasound in Obstetrics &Gynecology, Volume 62, Issue 6, Page 867-874, December 2023., 2023
ABSTRACT Objective Placental infection with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) can lead to placental insufficiency and in‐utero fetal death (IUFD). The objective of this study was to confirm and quantify the extent to which fetoplacental infection with SARS‐CoV‐2 is a cause of fetal death.

Incorporating MicroRNA into Molecular Phenotypes of Circulating Tumor Cells Enhances the Prognostic Accuracy for Patients with Metastatic Breast Cancer

The Oncologist, Volume 24, Issue 11, Page e1044-e1054, November 2019., 2019
Abstract Background The molecular phenotype of circulating tumor cells (CTCs) was associated with clinical outcome of patients with breast cancer. CTCs isolated from patients with metastatic breast cancer (MBC) display a unique microRNA (miRNA) expression profile.

Amplification of Ovis aries papillomavirus type 2 DNA from an ovine cutaneous fibropapilloma

Veterinary Dermatology, Volume 35, Issue 2, Page 226-229, April 2024.
Seven of 60 Perendale sheep within a flock developed single or multiple exophytic masses on their distal hind limbs. A mass was excised from one sheep and histological evaluation revealed epidermal and mesenchymal proliferation, papillomavirus‐induced keratinocyte changes and marked keratohyalin clumping.

TIPE expression in gastric cancer and its clinical significance [PDF]

, 2015
背景及意义：胃癌是严重危害人类健康的最常见的恶性肿瘤之一，发病率位居所有恶性肿瘤的第二位，死亡率列所有恶性肿瘤的第三位，目前临床上大多数患者确诊胃癌时已是中晚期，根治性手术仍然是胃癌的主要治疗方式，也是唯一有希望治愈胃癌的手段，但手术效果不佳，直接影响愈后。因此深入研究胃癌发生、发展的分子机制，可为胃癌早期诊断提供依据，同时也为临床治疗提供有效的靶点治疗，具有重要的临床意义。肿瘤坏死因子α诱导蛋白8（Tumornecrosisfactor-αinducedprotein-8，TIPE，TNFAIP8 ...

The role of histone acetylation in Rheumatoid arthritis peripheral blood mononuclear cells [PDF]

, 2016
研究背景类风湿关节炎（rheumatoidarthritis，RA）是一种常见的全身性自身免疫疾病，以慢性、进行性、侵袭性关节炎为主要临床表现。该病发病机制尚不明确，研究其发病机制对临床指导治疗具有极其深远的意义。组蛋白乙酰化在RA的发病机制中具有重要作用。组蛋白乙酰化是一种可逆的动态过程，主要由组蛋白乙酰转移酶(histoneacetylase，HATs)和组蛋白去乙酰化酶(histonedeacetylases，HDACs）协调修饰。既往研究中，Huber，L.C.等人的研究显示 ...
