Article Details
While African Health Sciences has been freely accessible online there have been questions on whether it is Open Access or not. We wish to clearly state that indeed African Health Sciences is Open Access. There are key issues regarding Open Access needing clarification for avoidance of doubt:
- 1. Henceforth, papers in African Health Sciences will be published under the CC BY (Creative Commons Attribution License) 4.0 International. See details on https://creativecomons.org/)
- 2. The copyright owners or the authors grant the 3rd party (perpetually and in advance) the right to disseminate, reproduce, or use the research papers in part or in full, format/medium as long as:
- No substantive errors are introduced in the process
- Attribution of authorship and correct citation details are given
- The referencing details are not changed.
Should the papers be reproduced in part, this must be clearly stated.
- 3. The papers will be freely and universally accessible online in an easily readable format such as XML in at least one widely recognized open access repository such as PUBMED CENTRAL.

Main Article Content
The balance between CD4+ T helper 17 and T-cell immunoglobulin and mucin domain 3 is involved in the pathogenesis and development of atrial fibrillation
Abstract
Background: To investigate the expression of Th17, T lymphocyte immunoglobulin mucin 3 (TIM-3+) cells and their related
cytokines in atrial fibrillation (AF) and their clinical significance.
Methodology: A total of 90 patients with AF were divided into paroxysmal group (n=45) and chronic group (n=45), and 45
healthy volunteers were selected as the control group. The proportion of Th17 cells and Tim-3 + cells in the peripheral blood
were detected. The concentrations of related cytokines in peripheral blood serum were determined. The correlation between
Th17 / Tim-3+ cells and related cytokines was analysed.
Results: Compared with the control group, the proportion of Th17 cells and the concentration of related cytokines (IL-17, IL-6
and Matrix metalloproteinase (MMP9)) in peripheral blood of patients with paroxysmal and chronic AF increased significantly,
while the proportion of tim3 + cells and the concentration of related cytokines decreased significantly. Compared with the
paroxysmal group, the proportion of Th17 cells and the concentration of related cytokines in the peripheral blood of patients
in the chronic group increased significantly, while the proportion of tim3 + cells and the concentration of related cytokines
decreased significantly.
Conclusion: Th17 / Tim-3 + cell balance is involved in AF, and can be used as a target for AF treatment.
