ABSTRACT
Objective To analyze the correlation between vitamin D levels and vascular endothelial function and plasma renin activity (PRA) in hypertensive patients.Methods 415 patients with essential hypertension admitted to our hospital from January 1 to December 2017 were selected as the experimental group.142 healthy subjects who received physical examination and met the included indicators were selected as the control group.The blood biochemical indexes and the 25 (OH) D contents in the blood of two groups were detected and analyzed.The experimental group was divided into vitamin D mild deficiency group (15-30 mmol/L),severe deficiency group [25 (OH) D ＜ 15 mmol/L] and normal group [25 (OH)D ＞ 30 mmol/L] according to vitamin D content.The endothelial function (RHI value) and renin were compared in the three groups,and multiple linear regression analysis was performed on endothelial function and orthotopic renin activity and related factors.Results The diastolic blood pressure,vitamin D content and blood lipid biochemical indexes of the experimental group and the control group were significantly different (P ＞ 0.05).The higher the vitamin D content,the lower the plasma renin activity PRA;the RHI value of the vitamin D severe deficiency group was lower than the vitamin D normal group [(1.4 ±0.15)mmol/L vs (1.6 ± 0.20) mmol/L] (P ＜ 0.05).Vitamin D was negatively correlated with 24 hours systolic blood pressure (24 h SSD),the standard deviation of 24 hours diastolic blood pressure (24 h DSD),the Standard deviation of daytime systolic blood pressure (dSSD),the Standard deviation of daytime diastolic blood pressure (dDSD),the Standard deviation of nighttime systolic blood pressure (nSSD),the Standard deviation of nighttime diastolic blood pressure (nDSD) (P ＜ 0.05),and positively correlated with the decrease of night systolic blood pressure and night diastolic blood pressure.Vitamin D and total cholesterol were independent influencing factors of endothelial function (P ＜ 0.01).Vitamin D and 24 h mean heart rate were independent influencing factors of orthostatic renin activity (P ＜ 0.01).Conclusions The low vitamin D content in patients with essential hypertension affects endothelial function and plasma renin activity,which should be paid more attention in clinical practice.
ABSTRACT
OBJECTIVE@#To evaluate symptoms and quality of life in children with allergic rhinitis, and to evaluate the correlations among the skin prick tests results, symptoms and quality of life.@*METHOD@#Visual analog scale (VAS) was used to assess the symptoms severity, rhinoconjunctivitis quality of life questionnaire (RQLQ) was used to assess quality of life, the skin prick tests results were recorded, and statistics analysis was carried out among them.@*RESULT@#(1) There were significant differences among the five aspects of RQLQ (F = 32.03, P < 0.01), nasal symptoms aspect was the most affected aspect of quality of life, moreover, there were significant differences among all the items of RQLQ (F = 7.35, P < 0.01), the scores of nasal blockage, sneezing and rhinorrhea were the highest, there were no significant differences among them. (2) VAS was significantly correlated with RQLQ, moreover, the scores of unable to get to sleep and embarrassed by symptoms were significantly correlated with rhinorrhea VAS scores (r = 0.230, P < 0.05; r = 0.325, P < 0.01), the score of wake up during the night was significantly correlated with nasal itching and sneezing VAS scores (r = 0.385, P < 0.01; r = 0.231, P < 0.05), the score of can't concentrate was significantly correlated with the scores of unable to get to sleep and wake up during the night (r = 0.316, P < 0.01; r = 0.525, P < 0.01), the score of irritable was significantly correlated with the scores of unable to get to sleep (r = 0.243, P < 0.05). (3) The results of the skin prick tests were related with VAS and RQLQ.@*CONCLUSION@#Nasal symptoms severity may significantly correlated with the quality of life. Rhinorrhea, nasal itching and sneezing may be the main factors affecting the quality of sleep, while the quality of sleep may affect non-hay-fever symptoms and emotions, rhinorrhea may be the main factor affecting embarrassed by symptoms. The allergen level was related with the symptoms severity and quality of life.
