ABSTRACT
Objective:To analyze the related factors affecting the inter-arm systolic blood pressure difference (IASBPD) in a physical examination population.Methods:A total of 3 600 adults who underwent physical examination and completed the arteriosclerosis test in the first affiliated hospital of Anhui medical university from January 2019 to June 2021 were selected as the participants by systematic sampling method. Data on age, sex, and history of smoking, heavy drinking, hypertension, type 2 diabetes, and coronary heart disease were recorded. The height, weight, waist circumference, hip circumference, total muscle, total fat and body fat ratio were measured, and body mass index was calculated. The blood pressure of the limbs, ankle brachial index (ABI) were measured synchronously with the arteriosclerosis tester of the Chinese Academy of Sciences, and the IASBPD were calculated. According to the IASBPD value, the participants were divided into two groups: IASBPD<10 mmHg (1 mmHg=0.133 kPa) group and IASBPD≥10 mmHg group, The differences between the two groups were compared, and the related influencing factors of IASBPD were analyzed by multivariate logistic regression.Results:Weight, body mass index, waist circumference, hip circumference, systolic blood pressure, diastolic blood pressure, total muscle, total fat, body fat rate, history of hypertension, proportion of type 2 diabetes mellitus, and proportion of history of coronary heart disease in the IASBPD≥10 mmHg group was higher than that of IASBPD<10 mmHg group [(69.1±11.2) vs (65.3±10.8) kg, (25.6±3.4) vs (24.4±3.3) kg/m 2, (91.3±11.3) vs (87.8±10.6) cm, (98.5±10.4) vs (96.5±9.8) cm, (139.7±20.0) vs (129.7±17.6) mmHg, (80.3±11.6) vs (76.7±10.1) mmHg, (47.5±9.1) vs (45.3±8.8) kg, (19.4±7.0) vs (17.6±6.4) kg, (27.9%±8.5%) vs (26.8%±8.1%), 41.1% vs 29.3%, 16.6% vs 11.7%, 13.1% vs 7.3%] (all P<0.05); ABI was lower than that in IASBPD<10 mmHg group [(1.15±0.11) vs (1.20±0.09)] ( P<0.001). There were no significant differences in height, smoking history and heavy drinking history between the two groups (all P>0.05). Multivariate logistic regression analysis showed that age, systolic blood pressure, body weight and ABI were independent influencing factors of IASBPD≥10 mmHg. Age, systolic blood pressure and body weight were positively correlated with IASBPD≥10 mmHg, while ABI was negatively correlated with IASBPD≥10 mmHg. Conclusion:Increases in age, systolic blood pressure, and body weight and a decrease in ABI are important influencing factors leading to the elevation of IASBPD.
ABSTRACT
BACKGROUND@#The incidence of lung cancer is increasing annually. Clinicians pay special attention to lung tests during physical examinations. Due to the popularity of low-dose computed tomography, not only can lung cancer be diagnosed early, but physical examinations often reveal the presence of pulmonary nodules, an important health issue that cannot be ignored. Patients with pulmonary nodules are prone to adverse emotions such as anxiety and depression. Many studies have shown that patients with emotional disorders have immune system dysfunction and changes in inflammation levels. This study aimed to investigate the changes in anxiety, depression, the ratios of T helper cells 17 (Th17) and regulatory T cells (Tregs), and inflammation levels in patients with pulmonary nodules.@*METHODS@#A total of 143 subjects from The First Affiliated Hospital of Anhui Medical University were included from April 2019 to July 2019. All of the subjects were assessed with the Beck Anxiety Inventory (BAI) and the Beck Depression Inventory-II (BDI-II). Overall, 40 cases were healthy controls (HC) and 103 cases were patients with pulmonary nodules. The patients were divided into two groups according to the scale scores: 62 cases in a non-anxiety and non-depression (NAD) group and 41 cases in an anxiety and/or depression (AD) group. The percentage of Th17 and Tregs in the peripheral blood and inflammatory factors in the serum were detected. The absolute Th17 cell counts were calculated and the differences between the groups and correlations between these indicators were analyzed.@*RESULTS@#There were statistically significant differences in the percentage of Th17 cells, the absolute counts of Th17 and Th17/Treg cells, and the levels of interleukin-2 (IL-2), IL-6, and tumor necrosis factor-α (TNF-α) among three groups (all P0.05). The previously described indicators had no significant correlation with the severity of anxiety and depression (P>0.05). There were no significant differences in the percentage of Tregs or levels of IL-4 and IL-10 between the groups (all P>0.05). The proportion of anxiety and/or depression in female patients with pulmonary nodules was higher than that in males (P<0.05).@*CONCLUSIONS@#Patients with pulmonary nodules are prone to varying degrees of anxiety and depression, which leads to immune dysfunction and low-grade inflammation.
ABSTRACT
Objective:To explore the association between serum 25-hydroxyvitamin D [25-(OH)D] and high-sensitivity C reactive protein (hs-CRP) levels in health check-ups population.Methods:A total of 746 patients who underwent health check-ups at an enterprise unit in Hefei city were selected as the study subjects with an average age of (47.2±15.6) years and 489 males, accounting for 65.5%. Demographical and disease information was collected through questionnaires. Serum 25-(OH)D and hs-CRP levels were measured. The subjects were divided into three groups according to the 25-(OH)D level: non-deficient group (≥50 nmol/L), deficient group (25 nmol/L to 49.9 nmol/L), severely deficient group (<25 nmol/L). C-reactive protein was divided into normal group and high value group by 75% percentile. Multivariate logistic regression was used to analyze the relationship between 25-(OH)D and hs-CRP levels.Results:The proportions of high CRP levels in the severely deficient, deficient, and non-deficient groups were 29.8%, 26.4%, and 17.0%, respectively, and the difference was statistically significant (χ2=6.471， P<0.05). Logistic regression analysis showed that, compared with the non-deficient group of 25-(OH)D, the odds ratios values (95% CI) of the high values of hs-CRP in the deficient group and the severely deficient group of 25-(OH)D were 1.851(1.122 to 3.053) and 2.369(1.227 to 4.573), respectively. Conclusions:Serum 25-(OH)D level is a risk factor for hs-CRP in adults. Nutritional intervention in vitamin D deficient population may be beneficial to reduce the level of inflammation.
