CCR9+CD4+ T cells are associated with disease activity in patients with rheumatoid arthritis.

An increase in CD4+ T cells in the synovium is closely linked to the pathogenesis of rheumatoid arthritis (RA). We aimed to identify the possible causes of the elevated CD4+ T cell levels and to explore the factors influencing disease activity in RA. Fifty-five RA patients, including 28 with active RA (ARA), 27 with inactive RA, and 22 healthy controls, were recruited for this study. The proportion of CCR9+CD4+ T cells and the expression of chemokine receptor 9 (CCR9) on CD4+ T cells were analyzed by flow cytometry. Enzyme-linked immunosorbent assay and chemiluminescent immunoassay were used to evaluate interleukin (IL)-17A and IL-6 levels, respectively. The proportion of CCR9+CD4+ T cells and the expression of CCR9 on CD4+ T cells increased significantly in peripheral blood (PB) and synovial fluid (SF) in ARA compared to those in inactive RA. Furthermore, SF contained more CCR9+CD4+ T cells, IL-6, and IL-17A than PB in RA patients. Moreover, CD4+ T cells in the PB of patients with RA, especially ARA, expressed more CCR9 and secreted more IL-6 and IL-17A after activation. Here, we also demonstrated that both the percentage of CCR9+ cells in CD4+ T cells and the expression of CCR9 on circulating CD4+ T cells were positively correlated with erythrocyte sedimentation rate, hypersensitive C-reactive protein, rheumatoid factor, and anti-cyclic citrullinated peptide antibody. CCR9+CD4+ T cells are elevated in PB and SF, and are associated with disease activity in patients with RA.

A relativity analysis on the incidence of thyroid-stimulating hormone and other biochemical markers of blood glucose and blood fat / 国际检验医学杂志

Objective To investigate the incidence of thyroid-stimulating hormone and its correlation with other biochemical markers of blood glucose and blood fat in health examination population.Methods Physical examination results of 1 070 staff from the First Affiliated Hospital of Hebei North University from January to May 2017,including serum thyroid-stimulating hormone(TSH),total cholesterol (CHOL),triglyceride (TG),and glucose (GLU),H bA 1 c were sorted,grouped by gender and age,and retrospectively analyzed.Results A total of 118 cases of TSH positive were detected,,the positive rate was 11.03 ％,of which 58 were male,the positive rate was 9.40％ and 60 were women,the positive rate was 13.25％,there was a statistically significant difference in the positive rate of TSH between two groups of male and female (x2=9.819,P＜ 0.05).TSH was positively related to TG,LDI,and GLU (r=0.006,0.048,0.021;P=0.038,0.017,0.045),and is negatively related to HDL(r=-0.017,P=0.024),and had no relation with CHOL and HbA1c(P＞ 0.05).There was a significant difference in the level of CHOL between the TSH group and the normal TSH groups (P＜0.05).Conclusion TSH has become a major factor affecting human health and should be highly valued.

Traditional culture education for newly recruited nurses establish positive and correct occupational self-concept / 中国实用护理杂志

Objective To guide new nurses to establish positive and correct occupational self-concept, enhance occupational identity and delay job burnout by adding traditional culture education in the standardized training for newly recruited nurses. Methods Randomly selected 56 new nurses of our hospital in recent years as research objects. 28 nurses enrolled in 2013 formed the experimental group and 28 nurses enrolled in 2014 formed the control group. The experimental group focused on nurses themselves. In the 10-month standardized training, 30 class-hour traditional culture education was added and more than 180 times of social practices were conducted; for the control group, only standardized training was carried out. Effects before and after, all subjects were examined occupational self-concept and desert jobs rate after work 2 years. Results The occupational self-concept of the experimental group tended to reach a positive level, which was (33.14±2.15) points, obviously higher than that of the control group, which was only (30.57 ± 3.03) points. Therefore, the difference was statistically significant(t=3.703 4,P0.05). Conclusions Adding traditional culture education in the standardized training for newly recruited nurses plays a positive role in promoting their occupational self-concept.
