Ovarian tissue cryopreservation for a girl with combined severe hemolytic anemia due to pyruvate kinase deficiency: a case report and literature review.

Objective: To present a young girl with pyruvate kinase deficiency (PKD) and concurrent severe hemolytic anemia who underwent fertility preservation and cryopreservation. Clinical symptoms, diagnosis, treatment, and new strategies for fertility protection and preservation in PKD patients who require allogeneic hematopoietic stem cell therapy are explored.

Case Presentation: Six-year-old girl with persistent unconjugated hyperbilirubinemia and severe hemolytic anemia since birth, continuous elevation of bilirubin levels and severe splenomegaly.

[A clinical analysis on the distribution characteristics of dermatophagoides pteronyssinus allergen components among children with allergic rhinitis and asthma in a hospital of pediatric in Shenzhen City from 2021 to 2024].

To investigate the distribution characteristics and analyze the clinical significance of dermatophagoides pteronyssinus allergen components in children with allergic rhinitis and asthma in Shenzhen. This study was a cross-sectional study. The clinical data of children with allergic rhinitis and asthma induced by dust mites admitted to the allergy clinic of Shenzhen Children's Hospital from 2021 to 2024 were collected and the serum sIgE levels of dermatophagoides pteronyssinus, dermatophagoides farinae (Der p, Der f) and dermatophagoides pteronyssinus components (Der p 1, Der p 2, Der p 10, Der p 23) were detected by magnetic bead chemiluminescence method.

Both carbon dots precursor and organic bridge ligands for coordination polymers: AMP-based ratiometric fluorescent probes and its application in bovine serum albumin detection.

Bovine serum albumin (BSA) is one of the most abundant proteins in serum, and its high-throughput detection is still one of the current challenges. Nitrogen‑phosphorus co-doped carbon dots (CDs) were synthesized by a hydrothermal method. Adenosine monophosphate (AMP) was used as a precursor for the synthesis of CDs, providing the required carbon, nitrogen and phosphorus sources for the CDs.

Maternal multivitamin supplementation mitigates the risk of fetal congenital heart disease associated with high indoor total volatile organic compounds exposure in east china: a case-control study.

Background: Congenital heart disease (CHD) is a common birth defect. Our previous studies suggest that indoor air pollution, especially total volatile organic compounds (TVOCs), may increase fetal CHD risk, whereas vitamin and folic acid (FA) supplements in early pregnancy might offer protection against CHD. However, limited research has explored whether FA or multivitamin supplementation can mitigate the effects of TVOCs exposure on CHD.

[Comparison on pharmacokinetics of six active components of Tripterygium wilfordii Polyglycosides Tablets between normal rats and rat model of adjuvant arthritis].

This work aimed to investigate the pharmacokinetics of six major blood-entering components(triptolide, triptophenolide, wilforgine, wilforine, tripterine, and wilforlide A) in Tripterygium wilfordii Polyglycosides Tablets(TWPT) between normal rats and the rat model of adjuvant arthritis, which was established by injection of Freund's complete adjuvant. Liquid chromatography-mass spectrometry(LC-MS) was employed to determine the content of six main components in the serum samples of normal and arthritic rats after administration of TWPT, and the pharmacokinetics of the six components were compared between normal and model rats. The specificity, linearity, accuracy, precision, stability, extraction recovery and matrix effect of the established LC-MS method all met the requirements.
