ABSTRACT
High-throughput sequencing technology, also known as next-generation sequencing technology, can explore new biomarkers and specific gene mutations. It has a pivotal role in promoting the gene research, which can limit the detection area, lessen the time needed for sequencing. Also, it can quickly screen out the suspected pathogenic genes of patients, gain the necessary genetic data, and provide the basis for clinical diagnosis and genetic counseling. In the research of corneal diseases, through the DNA sequencing of patients' diseased cells, it can provide a deeper understanding of corneal diseases and improve the diagnosis, classification and treatment alternatives of various corneal diseases. This article will introduce the application progress of high-throughput sequencing technology in corneal diseases, which will help to understand the application of this technology in various corneal diseases.

OBJECTIVE: To investigate the immunological parameters of chromic acid exposure among electroplating workers. METHODS: Forty-six subjects were selected from five electroplating plants in central Taiwan. Each subject was interviewed by questionnaire, and urine chromium (urine-Cr) concentration was assessed. Immunological parameters were evaluated by interleukin (IL-2, IL-4, IL-6, IL-8, IL-10, TNF-alpha, IFN-gamma) and levels of lymphocyte subsets (T-cell, B-cell, T4, T8 and T4/T8). RESULTS: Levels of IL-6 and IL-8 significantly increased in subjects with high urine Cr concentration, but TNF-alpha levels decreased. IL-2, IL-4, IL-10 and IFN-gamma were undetected. Flow cytometry was used to determine levels of lymphocyte subsets: only B-cells percentage had a negative correlation with urine-Cr. Smoking was an important factor that influenced levels of lymphocyte subsets. CONCLUSION: Exposure to Cr has a detrimental effect on the immune system, so it is evident that worker exposure to chromic acid in the electroplating workplace must be reduced to a minimum.
