Abstract
OBJECTIVE:To investigate the changes of lymphocyte subsets in the peripheral blood of patients with hepatitis C.METHODS:A total of 219 patients with hepatitis C and 66 healthy individuals served as normal controls were enrolled in the study. The proportions of T-lymphocytes (CD45(+)CD3(+), CD45(+)CD3(+)CD4(+), CD45(+)CD3(+)CD8(+)), B-lymphocytes (CD45(+)CD3(-)CD19(+)), NK-lymphocyte (CD45(+)CD3(-)CD16(+)56(+)) in peripheral blood were detected by flow cytometry.RESULTS:The count of peripheral lymphocyte subsets of patients with hepatitis C decreased from the stage of chronic infection to decompensated cirrhosis. The numbers of CD4(+), CD8(+)and NK lymphocytes of patients with chronic hepatitis C were significantly lower than those in healthy individuals (P<0.05). In the early and decompensated stage of hepatic cirrhosis, the numbers of lymphocyte subsets of patients were significantly lower than those in patients with chronic hepatitis C (P<0.01), and they were significantly lower in decompensated cirrhosis than in early cirrhosis (P<0.01). The proportion of B lymphocyte and CD4/CD8 ratio of patients increased from chronic infection to decompensated cirrhosis. Compared with chronic infection, the proportion of B lymphocyte and CD4/CD8 ratio in early and decompensated cirrhosis increased significantly (P<0.01 or P<0.05), while the proportion of NK lymphocyte was significantly reduced (P<0.01).CONCLUSION:From the stage of chronic infection to decompensated cirrhosis, patients with hepatitis C were found with the decreased numbers of CD4(+)T, CD8(+) T and NK lymphocytes, and the increased proportion of B lymphocyte and CD4/CD8 ratio.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
