4.Research progress on biomarkers of coal workers′ pneumoconiosis
China Occupational Medicine 2022;49(2):228-233
Coal workers' pneumoconiosis(CWP)is one of the most common occupational diseases. The pathogenesis of CWP
remains unclear and effective therapeutic drug is not exist. Therefore,looking for CWP-related biomarkers have become a focus
of research. In recent years,intensive studies have been carried out on the pathogenesis of CWP,such as inflammatory
response,alveolar epithelial cell injury,extracellular matrix remodeling,epigenetics,oxidative stress and immune dysfunction.
It has been found that some biomarkers were related to CWP,such as high mobility group protein 1,nucleotide-binding
oligomerization domain-like receptor family protein 3,surfactant protein,mucoprotein 5B,osteopontin,aminin,DNA
methylation,microRNA,long noncoding RNA,cytochrome b-245-alpha polypeptide and cluster of differentiation,and others.
These biomarkers are helpful for early screening,monitoring efficacy and pathogenesis research of CWP. However,it is
necessary to further explore biomarkers with high sensitivity and specificity and conduct prospective clinical value evaluation to
better guide the prevention and treatment of CWP .

Objective: Using MB-80 Microbiology Kinetic Rapid Reader, the methods were established to quantitatively measure the body fluid content of bacterial endotoxin and fungus in infectious patients. Methods: The blood samples were collected from Gram negative bacterial infection and deep mycosis patients and healthy volunteers. After pre-treatment, the plasma samples were measured using MB-80 system through kinetic turbidimetric limulus test method. The system computer could calculate the content of endotoxin and fungus during 1 hour detection. Results: The detection methods of endotoxin and fungus using MB-80 were simple and rapid. The process of pre-treatment was standardized and the results had good repeatability. The normal ranges of plasma endotoxin and fungus of human healthy volunteers were (2.03?2.32)ng/L and (2.46?2.15)ng/L respectively. The plasma endotoxin level of abdominal infection patients was increased significantly to 50-3 958 ng/L. The fungus level of deep mycosis patients was enhanced to 20-2 381 ng/L. Conclusion: The methods of endotoxin and fungus quantitatively measurement by MB-80 are simple and convenient and have results with good repeatability. The new detection methods of endotoxin and fungus can be used for diagnosis of endotoxemia and deep mycosis in early stage of infection.

Objectives:To study the alterations of NF-?B activation in PBMC, in order to clarify the signal transcription of NF-?B concerned in the mechanism of inflammatory reaction in severe burns. To evaluate the alterations of expression of NF-?B dependent proinflammatory cytokines mRNA. Thereby, to observe the regulating effects of NAC on NF-?B, and verify the medial effects of upstream signal molecules on cytokines expression. Methods:Sprague Dawley rats were randomly assigned to each group. A 30% TBSA full-thickness scald was performed by immersing in 100℃ water for 12 seconds. PBMC were isolated at different time point after scalding. From isolated PBMC, the total RNA was isolated and the nuclear protein purified by Trizol reagents. The NF-?B proteins were measured through EMSA. Message RNA expression of proinflammatory cytokines and Th2 cytokines were assayed by RT-PCR. Results:Lots of NF-?B proteins were sequester in nucleus in all burn groups. mRNA expression of proinflammatory cytokines were also enhanced and related to the activity of NF-?B protein in nucleus. NAC could decrease the activity of NF-?B protein in nucleus. NAC had also significantly inhibitory effects on the production of proinflammatory cytokines. However, all of Th2 cytokines measured in this study were enhanced too. Conclusions:NF-?B might be the second signal molecule from cytosol to nucleus and mediate the proinflammatory cytokines transcription in PBMC after burns. In signal transduction levels, enhancing scavengers of oxygen free radicals in PBMC may modulate the activity of NF-?B which mediate the expression of proinflammtory cytokines.
