Abstract:
Objective To investigate the expression and significance of CD19+CD24hiCD38hi regulatory B lymphocytes and secreted cytokine interleukin-10(IL-10)in hypertensive disorder complicating pregnancy.Methods A total of 15 patients with gestational hypertension(the gestational hypertension group)and 11 pa-tients with preeclampsia(the preeclampsia group)admitted to this hospital from September 2020 to May 2021 were selected,and 12 normal pregnant women(the control group)were selected during the same period.Flow cytometry was used to detect the expression of CD19+B lymphocytes,CD19+CD24hiCD38hi regulatory B lym-phocytes,and IL-10 in peripheral blood of three groups of pregnant women before termination of pregnancy.Results There was no statistically significant difference in the percentage of serum CD19+B lymphocytes a-mong the three groups(P＞0.05).The results of pairwise comparison showed that the percentage of serum CD19+CD24hiCD38hi regulatory B lymphocytes in the control group was higher than that in the gestational hy-pertension group,and it was higher than that in the preeclampsia group.And the differences between the con-trol group and the gestational hypertension group and the preeclampsia group were statistically significant(P＜0.05).The results of pairwise comparison showed that the serum level of IL-10 in the control group was higher than that in the gestational hypertension group,and it was higher than that in the preeclampsia group.And the difference between any two groups was statistically significant(P＜0.05).Conclusion CD19+CD24hiCD38hi regulatory B lymphocytes and secreted IL-10 are abnormally expressed in women with hypertensive disorder complica-ting pregnancy,which may be related to the occurrence and development of gestational hypertension.
