[Risk factors for bronchopulmonary dysplasia in preterm infants and establishment of a prediction model].

Objectives: To investigate the risk factors for bronchopulmonary dysplasia (BPD) in preterm infants, and to establish a risk prediction model.

Methods: A total of 120 preterm infants who were admitted to the neonatal intensive care unit of Shanghai Children's Hospital from January to December 2022 were included. According to the diagnostic criteria for BPD released by the National Institute of Child Health and Human Development in 2018, they were divided into a non-BPD group (84 infants) and a BPD group (36 infants).

The protective effects of Xuebijing injection on intestinal injuries of mice exposed to irradiation.

Background: Gastrointestinal (GI) injury is one of the most common side effects of radiotherapy. However, there is no ideal therapy method except for symptomatic treatment in the clinic. Xuebijing (XBJ) is a traditional Chinese medicine, used to treat sepsis by injection.

[Role of Th9, Th17, Treg Cells levels and IL-9, IL-17 and TGF-β Expression in Peripheral Blood of Patients with ITP in Pathogenesis of ITP].

Objective: To detect the levels of Treg, Th17, Th9 cells and expression of transforming growth factor-β (TGF-β), interleukin-17 (IL-17) and interleukin-9 (IL-9) in peripheral blood of patients with immune thrombocytopenia (ITP) and to explore its role in the pathogenesis of ITP.

Methods: Fifty-four patients with ITP (ITP group) and 40 healthy volunteers (control group) were selected in our hospital. The of Treg, Th17 and Th9 cells in peripheral blood of 2 groups were measured by flow cytometry, and the expression of cytokines, such as TGF-β, IL-17 and IL-9 in the peripheral blood of 2 groups were detected by enzyme linked immunosorbent assay (ELISA).

[Relation between single Nucleotide Polymorphisms of CYP3A5 Gene and MDR1 Gene Loci and Risk of CML Cytogenetic Relapse].

Objective: To analyze the relation between the signle nucleotide polymorphisms (SNP) of CYP3A5 gene and MDR1 gene loci and the risk of cytogenetic relapse in chronic myeloid leukemia (CML).

Methods: The clinical data of 90 patients with CML treated with imatinib in our hospital were collected.The patients were divided into 2 groups: non-relapse and relapse according to relapse and non-relapse, then the relation between the SNP of CYP3A5 gene and MRD1 gene loci and the risk of cytogenetic relapse in CML patients.

A novel tacrine-dihydropyridine hybrid (-)SCR1693 induces tau dephosphorylation and inhibits Aβ generation in cells.

AChE inhibitors are the first choice for the treatment of Alzheimer׳s disease (AD), but they could only delay the progression of cognitive and behavioral dysfunction, and fail to reverse neuronal damage. Calcium channel blockers have been identified to have protective effect on neurons. Thus, therapy targeting both AChE and calcium channels is supposed to be more effective in AD treatment.

Development of an electrochemical immunoassay for detection of gatifloxacin in swine urine.

To detect gatifloxacin (GAT) residue in swine urine, an electrochemical immunoassay was established. An indirect competitive immunoassay was developed, in which the coating antigen is immobilized in an enzyme-linked immunosorbent assay (ELISA) plate and GAT residue from the sample competes with the limited binding sites in added anti-GAT antibody. Horseradish peroxidase (HRP) conjugated to goat anti-rabbit IgG was used as the enzymatic label.
