ABSTRACT
Objective@# To investigate sodium and potassium intakes among individuals undergoing physical examinations in Changsha City, so as provide the evidence for developing nutritional interventions. @*Methods@#The individuals undergoing physical examinations in the Center for Health Management, The Third Xiangya Hospital of Central South University from February 2017 to March 2020 were selected, and their gender, age, history of diseases, history of medications, smoking and drinking behaviors were collected through questionnaire surveys. The blood pressure, height and body weight were measured, and the body mass index (BMI) was calculated. The levels of blood glucose, total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and serum creatinine were detected, and the 24-h urinary excretions of sodium and potassium were measured using the Kawasaki method to estimate sodium and potassium intakes. According to the recommended intakes for preventing chronic diseases (PI values) in the Chinese Dietary Reference Intakes (2013 revised version), the gender-, age- and BMI-specific intakes of sodium and potassium were analyzed.@*Results@#Totally 50 543 subjects were enrolled, with a mean age of (45.64±11.89) years. There were 28 555 men (56.50%) and 21 988 women (43.50%), and there were 19 405 overweight individuals (38.39%), 6 276 obese individuals (12.42%), 13 410 smokers (26.53%), 14 740 drinkers (29.16%), 9 217 individuals with hypertension (18.24%), 3 589 individuals with diabetes (7.10%), 18 232 individuals with dyslipidemia (36.07%). The mean sodium intake was (4 143.29±1 216.46) mg/d among the study subjects, and there were 49 277 participants with sodium intakes that exceeded the PI value (97.50%). Higher sodium intakes were found in men [ (4 345.52±1 231.45) mg/d ], individuals at ages of 36 to 45 years [ (4 185.41±1 202.95) mg/d ], obese individuals [ (4 578.94±1 282.66) mg/d ], smokers [ (4 191.71±1 219.91) mg/d ], drinkers [ (4 325.12±1 245.65) mg/d ], individuals with hypertension [ (4 358.89±1 265.70) mg/d ] and individuals with dyslipidemia [ (4 261.60±1 228.86) mg/d ]. The mean potassium intake was (1 986.26±526.42) mg/d among the study subjects, and there were 50 440 participants with potassium intakes that exceeded the PI value (99.80%). Higher potassium intakes were seen in men [ (2 061.94±556.91) mg/d ], individuals at ages of 35 years and below [ (2 027.24±533.37) mg/d ], obese individuals [ (2 133.27±580.25) mg/d ], smokers [ (2 023.08±557.72) mg/d ], drinkers [ (2 048.43±557.53) mg/d ], individuals without hypertension [ (1 994.65±552.63) mg/d ] and individuals with dyslipidemia [ (2 038.22±546.52) mg/d ].@*Conclusions@#Higher sodium intakes and lower potassium intakes than the PI values are found among individuals undergoing health examinations in Changsha City. Health education is recommended to be reinforced to improve sodium and potassium intakes.
ABSTRACT
Objective:To explore the relationship between different types of helicobacter pylori (Hp) infection and metabolic Syndrome (MS) in healthy population.Methods:The data of 4 602 adults who underwent physical examination in the Space Center Hospital from January to December 2019 were collected for research, the serum Hp antibody typing was detected by immunoblotting, and the results of liver ultrasound and blood biochemical examination were collected for statistical analysis.Results:Among the physical examination population,there were 2 018 cases with positive serum Hp antibody and 2 584 cases with negative serum Hp antibody.According to the expression of cytotoxin-associated gene A protein (CagA) and vacuolar toxin, 2 018 patients with positive serum Hp antibody were divided into 1 088 cases in type Ⅰ group (53.9%(1 088/2 018)) and 930 cases in type Ⅱ Group (46.1%(930/2 018)). There were significant differences in age, systolic blood pressure and prevalence of nonalcoholic fatty liver disease (NAFLD) between type Ⅰ group and type Ⅱ Group ( P<0.05). There was no significant difference in gender, fasting blood glucose, triglyceride,high-density lipoprotein cholesterol (HDL-C), diastolic blood pressure, body mass index (BMI) and waist circumference between the two groups ( P>0.05). There was no significant difference in the prevalence of ms between the two groups (18.3% (199/1 088)) and 19.0%(177/930), P=0.670). Multivariate logistic regression analysis showed that there was no correlation. between different serum Hp antibody typing and MS ( OR=1.194,95% CI 0.842-1.693, P=0.319). Conclusion:Different subtypes of type Ⅰ and type Ⅱ Hp infection are not distinctly associated with metabolic syndrome.
ABSTRACT
Objective To investigate the predicting value of intermedin (IMD) for the prognosis of elderly sepsis patients.Methods A retrospective analysis was conducted. Forty-one patients with sepsis, aged ≥65 years, and admitted to geriatrics intensive care unit of Aerospace Center Hospital from April 2015 to December 2016 were enrolled. Thirty healthy patients were studied as control during the same time. The expression of C-reactive protein (CRP), procalcitonin (PCT) and IMD were tested within 24 hours during hospitalization, and the acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score and prognosis was evaluated. According to APACHE Ⅱ score, patients were divided into 3 groups, 10-20 score, 21-30 score, and > 30 score group. And based on the prognosis, the patients were divided into death group and survival group. The differences of expression levels of CRP, PCT and IMD in each group were assessed. The relationship of IMD and infection index was analyzed by Pearson correlation. Receiver operating characteristic curve (ROC) was used to evaluate the prognostic value of CRP, PCT and IMD in patients with sepsis.Results Compared with the control group, the levels of CRP, PCT and IMD were significantly higher in the sepsis patients [CRP (mg/L): 114.71±40.08 vs. 4.03±2.68, PCT (μg/L): 1.338±0.812 vs. 0.007±0.001, IMD (ng/L):43.03±9.67 vs. 16.77±2.06, allP 30 score groups, PCT (μg/L) were 0.397±0.129, 1.164±0.326, and 1.999±0.888, respectively (F = 19.392,P = 0.000); IMD (ng/L) were 29.12±5.60, 40.48±4.40,52.75±4.73, respectively (F = 33.310,P = 0.000). There was no significant difference in CRP among APACHE Ⅱ score groups (F = 2.137,P = 0.132). The level of IMD was positively correlated with CRP and PCT (r1 = 0.351,P1 = 0.024;r2 = 0.617,P2 = 0.000), and there was no correlation with temperature and white blood cell count (r1 = 0.063,P1 = 0.697;r2 = 0.064,P2 = 0.692). The expression of PCT and IMD in the death groups were significantly higher than the survival group [PCT (μg/L): 1.547±0.883 vs. 1.043±0.608, IMD (ng/L): 47.44±8.23 vs. 36.80±8.13, bothP < 0.05], while CRP was not significantly different. The area under the ROC curve [AUC (95% confidence interval, 95%CI)] of IMD was larger than that of PCT and CRP [0.809 (0.675-0.943) vs. 0.680 (0.511-0.849), 0.664 (0.490-0.838)]; when cut-off value of IMD was 41.58 ng/L, the sensitivity was 75.0% and the specificity was 82.4%.Conclusions The levels of CRP, PCT and IMD were increased in elderly sepsis patients, and IMD and PCT can better reflect the severity of sepsis. IMD is more valuable in predicting the prognosis of sepsis patients.
