Atherosclerosis is nowadays recognized as a chronic inflammatory disease of large arteries. In recent years, cellular and molecular biology studies on atherosclerosis confirmed that the occurrence and development are related to inflammation and autoimmunity. A variety of immune cells, cytokines, and transcription factors are involved in this process. Current studies found that T helper cell 17, regulatory T cells, and their cytokines play an important role in the development of atherosclerosis and vulnerable plaque rupture. Here, we provide a review of the up-to-date applications of T helper cell 17, regulatory T cells, cytokines, and their balance in the prognosis and therapy of atherosclerosis.
Objective Hypertensive disorder complicating pregnancy (HDCP) is a unique and common obstetrical complication in pregnancy. The current study sought to investigate the diagnostic value of serum miR-204 in HDCP patients. Methods A total of 196 HDCP patients were enrolled, with 54 healthy pregnant women as controls. The expression levels of miR-204 and inflammatory factors in the serum were determined. Receiver operating characteristic (ROC) curve was used to assess the diagnostic value of miR-204 in HDCP patients. Person coefficient was introduced to analyze the correlation between miR-204 and inflammatory indexes. Kaplan–Meier method was employed to analyze the effect of miR-204 expression on the incidence of adverse pregnancy outcomes. Logistic regression was adopted to assess the risk factors for adverse pregnancy outcomes. Results miR-204 expression was upregulated in the serum of HDCP patients. The serum miR-204 level > 1.432 could assist the diagnosis of HDCP. miR-204 level in the serum was positively correlated with TNF-α, IL-6, and hs-CRP concentrations in HDCP patients. The risk of adverse outcomes was higher in pregnant women with high miR-204 expression. High miR-204 expression was associated with an increased risk of adverse pregnancy outcomes after adjusting the family history of HDCP, systolic pressure, diastolic pressure, AST, ALT, LDH, 24-h urinary protein, TNF-α, IL-6, and hs-CRP. Conclusion The high expression of miR-204 assists the diagnosis of HDCP and is an independent risk factor for adverse pregnancy outcomes in HDCP patients.
Hypertension is the most common pathological symptom during pregnancy, occurring in approximately 10% of all pregnancies. 1 As suggested by the American College of Obstetricians and Gynaecologists (ACOG), hypertensive disorders of pregnancy (HDPs) are classified into five categories: (a) chronic hypertension, (b) gestational hypertension, (c) preeclampsia, (d) eclampsia, and (e) preeclampsia superimposed on chronic hypertension. 1,2 Statistically, HDPs feature among the top six causes of maternal mortality in the United States Summary Endothelial progenitor cells (EPCs) are critical for vascular regeneration and function, but are reduced in hypertensive disorders of pregnancy. We aimed to determine the possible effects of antihypertensive drugs, such as metoprolol, methyldopa, and nifedipine, on EPC number and functions in patients with gestational hypertension and preeclampsia. We collected blood samples from 30 normal pregnant women, 67 patients with gestational hypertension and 48 patients with preeclampsia. The patients received no drug or an antihypertensive drug, such as metoprolol, methyldopa, or nifedipine, between 20 and 24 weeks of gestation. The number of EPCs and circulating endothelial cells (CECs) in the blood was measured by flow cytometry. Moreover, colony formation and migration assays were performed on the isolated EPCs. Both the systolic and diastolic blood pressure (BP) increased, while the percentage of flow-mediated vasodilatation (FMD) decreased in patients with gestational hypertension and preeclampsia, compared to the healthy controls at 20 weeks of gestation. CEC number increased in the patients, whereas EPC counts decreased.Furthermore, EPC colony formation and migration abilities were also impaired in the patients. However, administration of metoprolol, methyldopa, or nifedipine effectively restored the systolic and diastolic BP, FMD%, EPCs, and CEC numbers, as well as EPC migration capacity. Endothelial progenitor cells colony formation ability selectively improved with methyldopa and nifedipine. In patients receiving no drugs, most of these indexes worsened within 4 weeks (study duration). This study revealed a new pharmacological action of these antihypertensive drugs against gestational hypertension and preeclampsia, thus supporting their clinical use.
