Article Synopsis
- Circulating tumor DNA (ctDNA) contains unique genetic and epigenetic changes linked to ENKTL, allowing researchers to identify specific methylation markers relevant to the disease.
- A diagnostic prediction model based on these ctDNA markers shows high specificity and sensitivity, effectively correlating with tumor stages and patient responses to treatment.
- The developed prognostic model outperforms traditional systems in predicting outcomes and contributes to a personalized PINK-C risk grading system, enhancing treatment choices for ENKTL patients.
Objective: To prepare artificial antigens and anti-citrinin egg yolk-derived immunoglobulin (IgY) to build an enzyme-linked immunosorbent assay (ELISA) for citrinin (CTN).
Methods: CTN was conjugated with bovine serum albumin (BSA), ovalbumin (OVA) with formaldehyde condensation method to prepare artificial antigens and identified by ultraviolet (UV) spectrometry and Infrared (IR) spectrometry. Artificial antigens for CTN and anti-CTN IgY were purified with polyethylene glycol two-step precipitation method and identified by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE).
Neopterin and C-reactive protein (CRP) concentrations were determined in serum samples from 129 severe acute respiratory syndrome (SARS) patients and 156 healthy blood donors. In the patients with confirmed SARS, an early neopterin elevation was detected already at the day of onset of symptoms and rose to a maximum level of 45.0 nmol/L 3 days after the onset.

To define the dynamics of the immune spectrum in SARS, serum levels of cytokines, chemokines, immunoglobulins, complement and specific antibodies against SARS-associated coronavirus (SARS-CoV) were assayed by enzyme-linked immunosorbent assay (ELISA), and phenotypes of peripheral lymphocytes were analyzed by flow cytometry in 95 SARS-infected patients. Results showed that interleukin (IL)-10 and transforming growth factor beta (TGF-beta) were continuously up-regulated during the entirety of SARS.

Methods: On 75 HCC patients, PVC and HACE were respectively given at 2 weeks and 4 weeks after radical tumor resection. In 2nd week after surgery, 33 cases of them accepted Roferon-A treatment for 1 week.
