Development and characterization of human T-cell receptor (TCR) alpha and beta clones' library as biological standards and resources for TCR sequencing and engineering.

Characterization of T-cell receptors (TCRs) repertoire was revolutionized by next-generation sequencing technologies; however, standardization using biological controls to facilitate precision of current alignment and assembly tools remains a challenge. Additionally, availability of TCR libraries for off-the-shelf cloning and engineering TCR-specific T cells is a valuable resource for TCR-based immunotherapies. We established nine human TCR α and β clones that were evaluated using the 5'-rapid amplification of cDNA ends-like RNA-based TCR sequencing on the Illumina platform.

Clinicopathological characteristics of endometrial carcinoma with different molecular subtypes and their correlation with lymph node metastasis.

Endometrial carcinoma (EC) is one of the three major malignancies of the female reproductive organs. With intense research of tumor molecular mechanisms and development of precision medicine in recent years, the traditional pathomorphological classification fails to meet the needs of clinical diagnosis and treatment for EC. This study aims to analyze the correlation of different Proactive Molecular Risk Classifier for Endometrial Cancer molecular subtypes with lymph node metastasis (LNM) and other clinical features in EC.

Enhanced T cell activation and cytotoxicity against AML via targeted anti-CD99 nanoparticle treatment.

CD99 is a transmembrane protein overexpressed in Acute Myeloid Leukemia (AML), presenting a potential novel therapeutic target. Our group has previously developed anti-CD99-A192 (α-CD99-A192), comprising of single chain variable fragment (scFv) and elastin-like polypeptides (ELPs), and reported promising anti-leukemic activity in AML preclinical models. Treatment with α-CD99-A192 induced apoptosis in AML cell lines and prolonged survival in AML xenograft models.

FLT3/CD99 Bispecific Antibody-Based Nanoparticles for Acute Myeloid Leukemia.

Unlabelled: Cluster of differentiation 99 (CD99) is a receptor that is significantly upregulated in acute myeloid leukemia (AML). FMS-like tyrosine kinase 3 internal tandem duplication mutation in AML (FLT3-ITD AML) exhibits even higher levels of CD99 expression. Our group previously employed a novel peptide platform technology called elastin-like polypeptides and fused it with single-chain antibodies capable of binding to FLT3 (FLT3-A192) or CD99 (CD99-A192).

A study evaluating liquid-based endometrial cytology test and transvaginal ultrasonography as a screening tool for endometrial cancer in 570 postmenopausal women.

Objective: To evaluate the combination of transvaginal ultrasonography (TVS) and endometrial cytology test (ECT) as a potential diagnostic strategy for endometrial cancer and endometrial precancerous lesions in postmenopausal patients.

Methods: 570 postmenopausal patients admitted in our hospital due to abnormal bleeding or other symptoms and/or with endometrium thickness over 5 mm on ultrasound. The endometrial thickness was evaluated by TVS.

Application of short tandem repeat (STR) genotyping in partial hydatidiform mole.

Objective: The short tandem repeat (STR) technique, which is currently the most extensively applied genetic marker, works mainly due to the differences in DNA repeats, resulting in a rich population polymorphism and high genetic stability. This paper primarily investigated the application of STR genotyping in partial hydatidiform mole (PHM).

Methods: The clinical data of 31 PHM patients and 23 hydropic abortion patients diagnosed in the Pathology Department of Beijing Tsinghua Chang Gung Hospital from 2017 to 2022 were collected and retrospectively analyzed.

Rigorous benchmarking of T-cell receptor repertoire profiling methods for cancer RNA sequencing.

The ability to identify and track T-cell receptor (TCR) sequences from patient samples is becoming central to the field of cancer research and immunotherapy. Tracking genetically engineered T cells expressing TCRs that target specific tumor antigens is important to determine the persistence of these cells and quantify tumor responses. The available high-throughput method to profile TCR repertoires is generally referred to as TCR sequencing (TCR-Seq).

Deletion of CD36 exhibits limited impact on normal hematopoiesis and the leukemia microenvironment.

Background: CD36 has been identified as a potential therapeutic target both in leukemic cells and in the tumor immune microenvironment. In acute myeloid leukemia (AML), we found that APOC2 acts with CD36 to promote leukemia growth by activating the LYN-ERK signaling. CD36 also plays a role in lipid metabolism of cancer associated T-cells leading to impaired cytotoxic CD8 T-cell and enhanced T cell function.

Clinical characteristics and prognostic characterization of endometrial carcinoma: a comparative analysis of molecular typing protocols.

Background: Endometrial carcinoma (EC) is one of the most common gynecological malignancies in China and globally, accounting for the fourth-prevalent cancer in women. Although numerous studies have confirmed prognostic value of The Cancer Genome Atlas (TCGA) molecular subgroups, it is unclear how they are combined with histological features. The main objective of this study was to compare ProMisE and TCGA classification for the rapid and accurate prediction of prognosis within EC patients, together with the provision of a revised strategy for individualized diagnosis and treatment of patients.

Effects of Vinyl Functionalized Silica Particles on Thermal and Mechanical Properties of Liquid Silicone Rubber Nanocomposites.

It is very important to develop a new method of preparing high-performance liquid silicone rubber-reinforcing filler. Herein, the hydrophilic surface of silica (SiO) particles was modified by a vinyl silazane coupling agent to prepare a new type of hydrophobic reinforcing filler. The structures and properties of modified SiO particles were confirmed using Fourier-transform infrared spectroscopy (FT-IR), X-ray photoelectron spectrometer (XPS), specific surface area and particle size distribution and thermogravimetric analysis (TGA), the results of which demonstrated that the aggregation of hydrophobic particles is greatly reduced.

The role of upper and lower genital tract microbiota alterations in term chorionamnionitis: A prospective study.

Objective: This study aimed to compare the dynamics of lower and upper genital tract microbiota in normal term pregnancy, histological chorioamnionitis (HCA), and clinical chorioamnionitis (CCA) patients to provide a reference for the diagnosis and treatment of chorioamnionitis (CAM) patients.

Methods: We prospectively collected vaginal and cervical secretions, as well as placenta tissues, fetal membranes, and amniotic fluid from normal-term pregnant women, HCA and CCA patients. Then, we performed genomic DNA extraction and PCR amplification for all samples.

A risk score system for predicting complicated appendicitis and aid decision-making for antibiotic therapy in acute appendicitis.

Background: Exclusive antibiotic therapy is a feasible treatment option for uncomplicated appendicitis, but the pre-treatment diagnosis of uncomplicated appendicitis is challenging. This study aimed to develop a risk score system to predict complicated appendicitis and aiding decision-making regarding antibiotic therapy for acute appendicitis.

Methods: The risk score system for predicting complicated appendicitis was constructed and validated by a surgical therapy cohort (n=543).

Predictors and risk factors for intestinal necrosis in patients with mesenteric ischemia.

Background: Mesenteric ischemia results in blood flow that is insufficient to meet metabolic demands and subsequent dysfunction of visceral organs, including arterial obstruction and venous thrombosis. Sustained mesenteric ischemia exhausts the ability of capillaries to provide oxygen and initiate an inflammatory reaction, and eventually leads to intestinal mucosal necrosis, a serious and potentially life-threatening condition. Therefore, it is essential that the predictors and risk factors for intestinal necrosis in patients with mesenteric thrombus are explored.
