Abstract:
Abstract: Objective To explore the effect of Yiaikang on the expression of sterile alpha motif and histidine-aspartic acid domain-containing protein 1(SAMHD1), a host restriction factor, and interferon levels in peripheral blood of HIV-infected patients with lung-spleen Qi deficiency syndrome. This aims to provide insights into the mechanism of YiaiKang in the treatment of AIDS. Methods According to the diagnostic criteria of Western medicine for AIDS and traditional Chinese medicine for lung-spleen Qi deficiency syndrome, 22 cases of HIV patients with lung and spleen Qi deficiency syndrome were enrolled in the study from the First Affiliated Hospital of Henan University of TCM between September 2020 and May 2021, and 20 healthy people in the area were taken as control. The patients with lung and spleen Qi deficiency syndrome were treated with Yiaikang for 6 months. T lymphocyte subpopulation changes and expression level of SAMHD1 protein in T cells were detected by flow cytometry. SAMHD1 mRNA expression in peripheral blood mononuclear cells (PBMCs) was detected by fluorescence quantitative PCR. The levels of IFN-α, IFN-β, IFN-γ, and IL-2 in plasma were detected by enzyme-linked immunosorbent assay (ELISA). The changes of SAMHD1 and interferon in peripheral blood of HIV patients with lung and spleen Qi deficiency syndrome were analyzed to explore the intervention effect of Yiaikang. Results Compared with healthy people, HIV patients with lung and spleen Qi deficiency syndrome exhibited a reduction in the CD4 + T lymphocyte count and CD4/CD8 ratio (Z=-3.526, P<0.001; Z=-0.881, P<0.001). There was an increase in the expression of SAMHD1 protein in T lymphocytes (SAMHD1 MFI/CD4: Z=-3.425, P=0.001; SAMHD1 MFI/CD8: Z=-2.153, P=0.031) and an increase in the expression of SAMHD1 gene in PBMCs (Z=-3.828, P<0.001). Yiaikang treatment significantly increased the CD4 + T cell count and CD4/CD8 ratio (Z=-2.711, P=0.007; Z=-2.062, P=0.039), decreased the expression of SAMHD1 mRNA (Z=-2.581, P=0.010), and decreased the levels of IFN-α and IFN-γ (Z=-1.985, P=0.047; Z=-2.744, P=0.006). Conclusions Patients with lung-spleen Qi deficiency syndrome have reduced numbers of CD4 + T cells and CD4/CD8 ration, with increased expression of SAMHD1 and interferon factors. Yiaikang treatment can increase the number of CD4 + T cells and CD4/CD8 ratio and reduce the expression of SAMHD1 and interferon factor, thereby improving the immune imbalance caused by HIV infection.
