RESUMEN
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.
RESUMEN
Objective:To explore the clinical value of adenosine stress myocardial contrast echocardiography in detecting myocardial blood perfusion abnormalities in patients with type 2 diabetes mellitus.Methods:Twenty-six patients with type 2 diabetes mellitus clinically diagnosed from May 2019 to January 2020 in the endocrinology department of Fuwai Central China Cardiovascular Hospital and 28 healthy examinees with gender and age matched during the same period were enrolled. Routine echocardiography, rest and adenosine stress myocardial contrast echocardiography were performed, the plateau signal intensity(A value), curve rising slope(K value) and A×K value of the myocardial perfusion time-intensity curve were obtained by offline analysis. And general data such as age, gender, disease course, body mass index and glycated hemoglobin were collected, and results of the two groups were compared statistically.Results:In the rest state, the A value of the myocardial perfusion parameter in the diabetic group was not significantly different from that of the control group, both in whole and in segments ( P>0.05), while the K value and A×K value of the myocardial perfusion parameters in the diabetic group were significantly lower than those in the control group ( P<0.05). In the stress state, the A value, K value and A×K value of myocardial perfusion parameters in the diabetic group were significantly lower than those in the control group, both in whole and in segments ( P<0.05). The detection rate of myocardial perfusion abnormality in the stress state was significantly higher than that in the rest state, and the difference was statistically significant ( P<0.05). The myocardial blood flow reserve in the diabetic group was negatively correlated with the course of disease and the level of glycated hemoglobin ( r=-0.580, P=0.020; r=-0.481, P=0.013). Conclusions:Adenosine stress myocardial contrast echocardiography can be used for detection of left ventricular myocardial perfusion abnormalities in patients with type 2 diabetes mellitus, which has great clinical application value.

@#Objective To study the effect of foot motor imagery on lower extremity motor function in hemiplegics after stroke. Methods 72 hemiplegics were randomly divided into two groups: the experiment group and the control group. Normal rehabilitation was performed in the both groups and motor imagery was added in the experiment group. They were assessed with lower extremity Fugl-Meyer Assessment (FMA) and gait analysis. Results The scores of FMA in knee, ankle and lower extremity, gait frequency and speed improved in experiment group more than in controls(P<0.05). Conclusion Foot motor imagery can improve lower extremity motor function.
