Prostaglandin E2 (PGE2) plays a crucial role in inflammation. Non-steroidal anti-inflammatory medications are commonly utilized to alleviate pain and address inflammation by blocking the production of PGE2 and cyclooxygenase (COX). However, selective inhibition of COX can easily lead to a series of risks for cardiovascular diseases.

Background: This study aimed to evaluate the efficacy of third-generation sequencing (TGS) and a thalassemia (Thal) gene diagnostic kit in identifying Thal gene mutations.

Methods: Blood samples (n = 119) with positive hematology screening results were tested using polymerase chain reaction (PCR)-based methods and TGS on the PacBio-Sequel-II-platform, respectively.

Results: Out of the 119 cases, 106 cases showed fully consistent results between the two methods, with TGS identified HBA1/2 and HBB gene mutations in 82 individuals.

Oxidative stress caused by pregnancy-induced hypertension syndrome significantly affects the health of pregnant women. Hydrogen sulfide is a typical gaseous signal molecule against oxidative stress, and it is of profound significance to develop a detection method. In this study, a stimuli-responsive hydrogel was constructed based on the coordination and bonding principle of metal ions and chitosan (CS) to realize the quantitative detection of hydrogen sulfide (HS).

Background: This study aims to explore the infection and age distribution of Ureaplasma urealyticum (UU), Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Herpes simplex virus type II (HSV II) among the outpatients of Reproductive Medicine Center in Putian, Fujian Province to provide a clinical basis for the early diagnosis and treatment of various reproductive tract diseases and infertility in this region.

Methods: A total of 1736 samples of secretions and exfoliated cervical cells were collected from the outpatients of the Reproductive Medicine Center of the Affiliated Hospital of Putian University from December 2021 to April 2023. The infections of UU, CT, NG and HSVII were detected by real-time fluorescence polymerase chain reaction (PCR), and the infection statuses of the patients with different genders, ages and diagnoses were analysed.

Article Synopsis
  • 2,5-dimethylcelecoxib (DMC), a derivative of celecoxib, shows potential in inhibiting hepatocellular carcinoma (HCC) growth by enhancing the activity of natural killer (NK) and T cells while decreasing tumor progression through modulation of immune responses.
  • Using high-dimensional mass cytometry and 16S ribosomal RNA sequencing, the study revealed that DMC not only boosts the immune response but also remodels the gastrointestinal microbiota, which contributes to its antitumor effects.
  • Findings highlight DMC's unique mechanism of reducing programmed cell death protein-1 expression and increasing interferon-γ levels in immune cells, suggesting its importance for potential immunotherapy

Background: The infection rate of human papillomavirus (HPV) is high in the coastal regions of China. However, the infection rate among high-risk genotypes of women in Putian City is unknown. Therefore, this study aimed to analyse the epidemiology of high-risk HPV infection among women in Putian and provide a reference for the diagnosis, treatment and vaccination of cervical cancer in this region.

Nitrogen-doped carbon quantum dots (N-CQDs) with citric acid and ethylenediamine as raw materials were synthesized by an efficient one-step strategy. The N-CQDs showed a special property that the fluorescence was quenched by Fe. The quenched fluorescence of N-CQDs could be recovered by glutathione (GSH).
