Hypertensive disorders complicating pregnancy (HDCP) is a systemic disease among pregnant women. Therefore, the prevention and prediction of hypertension during pregnancy are critical. This study aimed to clarify whether the vascular endothelial function of women with gestational hypertension was linked to placental growth factor. A total of 200 pregnant women were enrolled in our study and subsequently divided into two groups: the HDCP group and the normal pregnancy controls. The levels of serum placental growth factor, as well as plasma endothelin-1 and nitric oxide, between the two groups were measured. In addition, the endothelial function indexes, including pressure-strain elasticity coefficient (EP), the common carotid stiffness index (β), arterial compliance, single-point pulsed-wave velocity, and augment index (AI) of bilateral common carotid arteries, were compared between the HDCP and control groups using the echo tracking technique. In our study, the level of placental growth factor in the HDCP group was significantly lower than the control group. Furthermore, our results clarified that endothelin-1 increased while nitric oxide decreased in the HDCP group compared with the control group. On the other hand, we found that EP, β, pulsed-wave velocity and augment index values were significantly higher in the HDCP group than in the control group (P < 0.001). However, the value of arterial compliance was significantly decreased in patients of the HDCP group compared with the control group (P < 0.001). In conclusion, the association between serum placental growth factor and vascular endothelial function in HDCP could serve as a more accurate predictive factor of pregnant hypertension.

Background: Remote ischemic preconditioning (RIPC) induced by brief episodes of ischemia of the limb protects against organ damage by ischemia-reperfusion. It has been reported that RIPC improves endothelial function of the forearm in normal subjects and patients with coronary artery disease. However, the digital vascular endothelial response to RIPC has not been determined in healthy volunteers. Methods: This study was performed to examine effect of RIPC on fingertip digital vascular endothelial function by using endothelial pulse amplitude tonometry (EndoPAT) device and alteration in circulating nitric oxide(NO) level in peripheral blood. Ten healthy adult subjects (5 men, 5 women, mean age 25.2 years) had 3 cycles of 5 min ischemia alternating with 5 min reperfusion of the forearm. Another 10 healthy volunteers (6 men, 4 women, mean age 26.2 years) were used as the control group of sham and the cuff was inflated for 3 times at 10 mmHg for 5 minutes with 5-minute intervals. Fingertip digital vascular endothelial function of the ipsilateral arm was measured prior to first ischemia, 3h and 6h after the last episode of ischemia. Blood samples were taken from the contralateral arm prior to first ischemia, 3h and 6h after the last episode of ischemia. Results: Fingertip digital vascular endothelial function was significantly increase in 3h and 6h after the last RIPC intervention compared with the baseline condition(p<0.05). In parallel the RIPC stimulus increased circulating NO formation(p<0.05). There is a close association between finger vascular endothelial function and NO formation(p<0.05). Conclusion: The present findings demonstrate for the first time that transient RIPC contributes to improvement of digital vascular endothelial function and increase in circulating NO production in healthy volunteers. Our data provide a novel evidence to support that RIPC might gain even wider application not only in disease but also in health.

The objective: evaluation of the effectiveness of the prevention of preeclampsia in pregnant women with obesity using L-arginine during pregnancy Materials and methods. Materials and methods. The main group consisted of 38 obese women (1st century – 15th, 2nd century – 12th, 3rd century – 11), who were prescribed complex prevention of preeclampsia: from 12 weeks of pregnancy 150 mg of aspirin once a day, and from 16 weeks the solution L-arginine (Тivortin aspartate) 5 ml (1 g) 4 times a day for 2 months. The comparison group included 30 pregnant women with obesity of the II-III stage who did not receive preventive treatment. The control group consisted of 30 healthy pregnant women. By the beginning of prophylactic treatment and in the dynamics of all obese pregnant women, the level of pregnancy-associated plasma protein A (PAPP-A), placental growth factor (PlGF), arginine and leptin was determined in blood serum. Results. In pregnant women with obesity, already in the first trimester a significantly higher level of leptin is observed compared to the main group and the level of placental growth factor is significantly lower, which are significant triggers for the development of preeclampsia and other gestational complications. After the prophylactic treatment of pregnant women of the main group with L-arginine for 2 months (at 16–24 weeks), the following trends were observed: the level of L-arginine did not change, was constant. Leptin levels differed depending on the degree of obesity, but did not have a high critical value. A positive trend was the growth of placental growth factor in women of the main group, which indicated normal placentation and the prevention of early preeclampsia. Conclusions. Thus, in pregnant women of the main group, after comprehensive prevention of the development of preeclampsia with aspirin and L-arginine (Тivortin) for 2 months, the incidence of severe severe preeclampsia decreased by 4.4 times, which is a favorable factor in maintaining a woman’s health and reducing perinatal losses. Additional L-arginine in the diet reduced the frequency of preeclampsia in pregnant women with obesity, contributing to vasodilation due to increased production of nitric oxide, may be one of the positive factors of pathogenetic treatment. Keywords: pregnancy, obesity, preeclampsia, leptin, nitric oxide, L-arginine.

The article presents the predictors of placental dysfunction on the early stage of pregnancy. The objective: the search for prognostic markers and criteria for the occurrence of placental insufficiency in the early stages of the gestational process to optimize the pregnancy and labor with improved perinatal outcomes. Patients and methods. To solve this goal in the period from 2013 to 2015 were conducted a comprehensive survey of 334 pregnant women, which depending on the peculiarities of pregnancy and childbirth were divided into groups. The control group consisted of 236 pregnant women with uncomplicated gestational period, no morphological signs of placental dysfunction. The study group included 98 patients with a complicated pregnancy who had revealed violations of the fetal-placental relations, which was confirmed by morphological examination of the placenta in the postpartum period. Results. It was found that pregnant women with placental insufficiency in the first trimester of pregnancy have higher levels of interleukin-1B (IL-1v) and interleukin-3 (IL-3) in comparison with physiological pregnancy, as well as there is a direct significant correlation between IL-1v and pulsative index (PI) in the spiral (r=0.84) and uterine artery (r=0.77), and the inverse correlation between the level of IL-3 and PI in the terminal branches of the umbilical artery (r=-0.69). Verified an inverse relationship between the concentration of endothelin-1, the level of vascular endothelial growth factor (r=-0.87) and placental growth factor (r=-0.73), and also a direct link between the content of endothelin-1 and PI in spiral arteries (r=0.89), uterine artery (r=0.83) and the terminal branches of the umbilical artery (r=0.79). Conclusion. Thus, it is proven that early predictors of placental dysfunction can be considered the concentration of endothelin-1, vascular endothelial growth factor, placental growth factor, interleukin-1, interleukin-3, and the indices of pulsative index. Key words: placental dysfunction, predictors, endothelin-1, vascular endothelial growth factor, placental growth factor, interleukin, pulsative index.

This study is to investigate the effect of atorvastatin combined with losartan on inflammatory factors, vascular endothelial function, and cardiovascular events in patients with diabetic nephropathy. A total of 128 patients with diabetic nephropathy treated in our hospital from January 2014 to December 2015 were selected as the study subjects, and 64 cases were randomly divided into observation group and 64 cases in the control group. The control group was treated with losartan on the basis of routine treatment, and the observation group was treated with atorvastatin on the basis of the control group. The blood lipid, inflammatory factors, changes in vascular endothelial function and cardiovascular events were compared between the two groups. The levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were not significantly different between the two groups before treatment ( P > 0.05); after treatment, the levels of TC, TG, and LDL-C in the observation group were significantly lower than those of the control group, and the level of HDL-C was significantly higher than that of the control group ( P < 0.05). The levels of high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor alpha (TNF-α), and interleukin 6 (IL-6) were not statistically different between the two groups before treatment ( P > 0.05); after treatment, the levels of hs-CRP, TNF-α, and IL-6 in the observation group were significantly lower than those of the control group ( P < 0.05), the level of HDL-C was significantly higher than that of the control group ( P < 0.05). There were no significant differences in the levels of endothelin-1 (ET-1) and nitric oxide (NO) between the two groups before treatment ( P > 0.05). After treatment, the level of ET-1 in the observation group was significantly lower than that of the control group ( P < 0.05), and the level of NO was significantly higher than that of the control group ( P < 0.05). After treatment, all patients were followed up for 2 years, and the incidence of secondary cardiovascular events in the observation group was 12.50% (8/64), which was significantly lower than 29.69% (19/64) of the control group ( P < 0.05). Combination of atorvastatin and losartan can significantly improve the levels of blood lipid, inflammatory factors, and vascular endothelial function in patients with diabetic nephropathy and can effectively reduce the incidence of cardiovascular events.

Background: We aimed to explore the effect of comprehensive cerebral protection on cerebral oxygen metabolism and vascular endothelial function in elderly patients with acute cerebral infarction. Methods: A total of 168 elderly patients with acute cerebral infarction treated in The First Affiliated Hospital of Nanchang University, China from January 2016 to January 2018 were selected. The patients were divided into a control group and an observation group using random number method, n=84. Patients in the observation group were given comprehensive cerebral protection treatment, and patients in the control group were treated with conventional standardized treatments. The changes of cerebral oxygen metabolism, hemorheology and vascular endothelial function before and after treatment were compared between the two groups. Results: After treatment, oxygen content in arteries and internal jugular veins (Da-vO2), ofoxygen uptake fraction (OEF), Oxygen saturation (SpO2), nitric oxide (NO) were increased in both groups in comparison to before treatment, jugular venous oxygen saturation (SjvO2), brain oxygen uptake rate (ERO2), endothelin (ET), intracranial pressure (ICP), whole blood viscosity, plasma viscosity, reduced viscosity of whole blood, and hematocrit were decreased. However, the changes in the observation group were larger than those in the control group, the difference was statistically significant (P<0.05). Conclusion: The treatment of cerebral infarction in elderly patients with acute cerebral infarction can effectively improve the cerebral oxygen metabolism and vascular endothelial function and improve the blood rheology, which has important clinical value.

Background: Pre-eclampsia(PE) is  the  most  frequently encountered  medical  complication  during  pregnancy. In developing countries PE   is a principal cause of maternal mortality. A disturbance  in  the  angiogenic/antiangiogenic  factors  and  in  the  hypoxia/placental re-oxygenation  process,  seems  to  activate a maternal  endothelial  dysfunction.Aims and Objective: To estimate Vascular Endothelial Growth Factor ( VEGF )  level  in the cord blood of healthy and Preeclamptic ( PEc ) pregnant women and to associate this with Preeclamptic pregnancy.Material and Methods: A case-control study ofUmbilical cord serum VEGF levels from women with uncomplicated pregnancies (control group, n=60) and pregnancies complicated by Pre-eclampsia (n=40). VEGF in the cord serum was estimated by SANDWICH Enzyme Linked Immunosorbent Assay method by using ELISA Kit and then compared between the two groups.Results: The mean VEGF concentrations in the women who had pre-eclampsia  (578.62±468.3)  were lower than in the control group( 625.75±533.1) , but the difference was not statistically significant ( p= 0.8548).  Conclusion VEGF plays a key role in the instability between endothelial dysfunction and angiogenesis that occurs during Preeclampsia.  VEGF levels might be a useful tool for the early diagnosis of Pre-eclampsia.Asian Journal of Medical Sciences Vol.8(1) 2017 21-25

To assess the variations in pulmonary function and vascular endothelial function in their early stages (without related complications). A total of 162 type 2 diabetes mellitus (T2DM) patients without diabetes complications and 55 healthy people were selected, comprising the T2DM group and the control group, respectively, to evaluate changes in vascular endothelial function and lung function and determine the correlation between them. In this study, the T2DM group exhibited significantly lower pulmonary function than that of the control group (P &lt; 0.05). The T2DM group also showed significantly lower flow-mediated dilation (FMD) and nitric oxide (NO) (P &lt; 0.05) than those of the control group. Pulmonary functional indexes correlated positively with FMD and NO (P &lt; 0.05) and correlated negatively with endothelin-1 (ET-1) (P &lt; 0.05). FMD and NO correlated negatively with diabetes duration/HbA1c (P &lt; 0.05), whereas ET-1 correlated positively with glycosylated hemoglobinA1c (HbA1c)/diabetes duration (P &lt; 0.05). Pulmonary functional indexes negatively correlated with HbA1c/diabetes duration (P &lt; 0.05). Multiple linear regression was used to analyze the relationship between vascular endothelial function indexes (FMD, ET-1, and NO) and pulmonary functional indexes. The results indicated that each vascular endothelial function index (FMD, ET-1, and NO) was significantly correlated with the pulmonary functional index (P &lt; 0.05). The patients with T2DM presented changes in the subclinical vascular endothelial and pulmonary function. They also had impaired vascular endothelial functions, which were characterized by reduced vascular endothelial function relative to those of healthy people. Regulating glycemia may improve vascular endothelial and pulmonary functions. Moreover, microvascular lesions in preclinical stages, vascular endothelial function indexes (FMD, ET-1, and NO) were valid predictors of alterations in pulmonary function in T2DM patients without related complications.Clinical Trial RegistrationClinicalTrials.gov, identifier NCT03575988.
