Article Synopsis
  • Recent guidelines suggest that individuals with prehypertension (130/80 to 139/89 mm Hg) should consider antihypertensive treatment; this study assesses the cost-effectiveness of three interventions: salt substitution, antihypertensive drugs, and their combination in Chinese adults.
  • A Markov cohort model was used to estimate the impact of these interventions on cardiovascular disease events, costs, and quality-adjusted life years (QALYs), utilizing data from the China Kadoorie Biobank.
  • The findings indicate that salt substitution is the most cost-effective strategy for prehypertensive individuals starting at age 40, while a combination intervention is best for those at high cardiovascular risk; beginning these interventions at younger ages can lead to more

Background: With the continuous innovation of magnetic resonance imaging (MRI) hardware and software technology, amide proton transfer-weighted (APTw) imaging has been applied in liver cancer. However, to our knowledge, no study has evaluated the feasibility of a three-dimensional amide proton transfer-weighted (3D-APTw) imaging sequence for hepatocellular carcinoma (HCC). This study thus aimed to conduct an image quality assessment of 3D-APTw for HCC and to explore its feasibility.

Background And Objectives: Neuromyelitis optica spectrum disorders (NMOSD) is widely recognized as a CNS demyelinating disease associated with AQP4-IgG (T cell-dependent antibody), and its trigger is still unclear. In addition, although the treatment of NMOSD currently can rely on traditional immunosuppressive and modulating agents, effective methods to predict the efficacy of these therapeutics are lacking.

Methods: In this study, high-throughput T-cell receptor (TCR) sequencing was performed on peripheral blood from 151 pretreatment patients with AQP4-IgG NMOSD and 151 healthy individuals.

Article Synopsis
  • Triple-negative breast cancer (TNBC) is a diverse group of tumors, with most being aggressive high-grade types, but a minority classified as non-high-grade and exhibiting less aggressive behavior.
  • A study examined 18 non-high-grade TNBCs, mostly with apocrine features, and found that they had low Ki-67 levels, with only 11% showing lymph node metastasis and no recurrences during an average follow-up of 38 months.
  • The tumors showed distinct genetic profiles, particularly involving the PI3K-PKB/Akt and RTK-RAS pathways, indicating that non-high-grade TNBCs are a unique subgroup with specific clinical behaviors that may require tailored treatment approaches.

The success of the two mRNA vaccines developed by Moderna and BioNTech during the COVID-19 pandemic increased research interest into the application of mRNA technologies. Compared with the canonical linear mRNA used in these vaccines, circular mRNA has been found to mediate more potent and durable protein expression and demands a simpler manufacturing procedure. However, the application of circular mRNA is still at the initiation stage, and proof of concept for its use as a future medicine or vaccine is required.

Introduction: Adoptive cellular therapy with tumor-infiltrating lymphocytes (TIL) has demonstrated promising clinical benefits in several solid tumors, but the efficacy of this therapy might be compromised by the "prone-to-exhaustion" phenotype of TIL and poor persistence in vivo. This calls for a robust expansion process to produce a large number of cells for clinical usage while at the same time maintaining favorable anti-tumor function and memory phenotype. Previous studies showed that the PI3K-AKT signaling pathway plays a key role in the regulation of T cell activation, differentiation and memory formation.

The continuous emergence of SARS-CoV-2 variants highlights the need of developing vaccines with broad protection. Here, according to the immune-escape capability and evolutionary convergence, the representative SARS-CoV-2 strains carrying the hotspot mutations were selected. Then, guided by structural and computational analyses, we present a mutation-integrated trimeric form of spike receptor-binding domain (mutI-tri-RBD) as a broadly protective vaccine candidate, which combined heterologous RBDs from different representative strains into a hybrid immunogen and integrated immune-escape hotspots into a single antigen.

Terahertz (THz) waves show great potential in nondestructive testing, biodetection and cancer imaging. Despite recent progress in THz wave near-field probes/apertures enabling raster scanning of an object's surface, an efficient, nonscanning, noninvasive, deep subdiffraction imaging technique remains challenging. Here, we demonstrate THz near-field microscopy using a reconfigurable spintronic THz emitter array (STEA) based on the computational ghost imaging principle.

Rationale: Epidemiological studies have identified an associate between iron deficiency (ID) and the use of oral contraceptives (CC) and ischemic stroke (IS). To date, however, the underlying mechanism remains poorly understood. Both ID and CC have been demonstrated to upregulate the level and iron-binding ability of Tf (transferrin), with our recent study showing that this upregulation can induce hypercoagulability by potentiating FXIIa/thrombin and blocking antithrombin-coagulation proteases interactions.

Background: Patients with mild or moderate chronic obstructive pulmonary disease (COPD) rarely receive medications, because they have few symptoms. We hypothesized that long-term use of tiotropium would improve lung function and ameliorate the decline in lung function in patients with mild or moderate COPD.

Methods: In a multicenter, randomized, double-blind, placebo-controlled trial that was conducted in China, we randomly assigned 841 patients with COPD of Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage 1 (mild) or 2 (moderate) severity to receive a once-daily inhaled dose (18 μg) of tiotropium (419 patients) or matching placebo (422) for 2 years.

Context: The WHO Technical Consultation recommends urinary iodine concentrations (UIC) from 250 to 499 μg/L as more-than-adequate iodine intake and UIC ≥ 500 μg/L as excessive iodine for pregnant and lactating women, but scientific evidence for this is weak.

Objective: We investigated optimal and safe ranges of iodine intake during early pregnancy in an iodine-sufficient region of China.

Method: Seven thousand one hundred ninety pregnant women at 4-8 weeks gestation were investigated and their UIC, serum thyroid stimulating hormone (TSH), free thyroxine (FT4), thyroid-peroxidase antibody (TPOAb), thyroglobulin antibody (TgAb), and thyroglobulin (Tg) were measured.
