Objective? To explore application effect of personalized nursing in heparin catheter-locking anticoagulant therapy of patients with fractures. Methods? Based on the convenience random number table method, a total of 90 fracture patients in Tangshan Gongren Hospital receiving heparin catheter-locking anticoagulant therapy from June of 2016 to October of 2018 were selected and divided into the observation group and control group with 45 cases in each group. The observation group was given routine nursing during the period of heparin catheter-locking anticoagulant therapy, on the basis of that, the observation group received personalized nursing intervention. The two groups were compared in the disappearance time of symptoms, blood loss after operation, coagulation function [platelet count (PLT), fibrinogen (FIB), D-dimer (D-D)]and complications before and after intervention. Results? The disappearance time of pain, swelling and ecchymosis in the observation group was shorter than that in the control group, but the blood loss was less than that in the control group (P＜ 0.05); the levels of PLT, FIB and D-D in the observation group were lower than those in the control group (P＜0.05); the incidence of complications in the observation group was 8.88%, lower than 26.66% in the control group one month after the intervention (P＜0.05). Conclusions? Personalized nursing intervention can improve the nursing quality for fracture patients under heparin catheter-locking anticoagulant therapy and improve their coagulation function and reduce the complications after catheterization.

Objective:To explore the association between cardiovascular health behaviors and hyperuricemia (HUA) among community residents of different age groups.Methods:It was a cross-sectional study. A total of 2 138 community residents aged (47.1±11.6) years with 1 012 males (47.3%) were selected by cluster sampling method as study subjects in Taiyuan Nanzhai Community from March to November 2020. There were 104 cases aged 8-18 years (underage group), 868 cases aged 19-44 years (youth group), 625 cases aged 45-59 years (middle-aged group), 375 cases aged 60-74 years (young elderly group), and 166 cases aged≥75 years (elderly group). Blood uric acid was measured and>420 μmol/L was defined as HUA, there were 385 cases with high uric acid level (HUA group) and 1 753 cases with normal uric acid levels (control group). The general information was collected by questionnaires, and general ergonomic indicators were measured on-site by medical personnel. The cardiovascular health behaviors included smoking, exercise, diet, and sleep in study subjects were documented. Multivariate logistic regression model was used to analyze the related factors of HUA.Results:Among 2 138 participants, 1 161 (54.3%) had never smoked (up to standard), and the order of proportion of non-smokers from high to low was underage group, elderly group, young elderly group, young group and middle-aged group ( P<0.001); 486(22.7%) people met the dietary standards, and the order of proportion of meeting the dietary standards from high to low was underage group, elderly group, young elderly group, middle-aged group, and young group ( P<0.001); 554(25.9%) people achieved physical fitness standards, and the order of the proportion of achieving physical fitness standards from high to low was young elderly group, middle-aged group, elderly group, underage group, and young group ( P<0.001); 783 (36.6%) people met the sleep standards, and the order of proportion meeting the sleep standards from high to low was underage group, youth group, middle-aged group, young elderly group, and elderly group ( P<0.001). Among the participants, only 39 (1.8%) met the standards for all 4 types of behaviors; 485 (22.7%), 1 229 (57.5%), and 424 (19.8%) had low, medium, and high total scores for ideal cardiovascular health behaviors, respectively. The total score of ideal cardiovascular health behaviors ranked from high to low was elderly group, young elderly group, underage group, middle-aged group, and young group ( P<0.001). The multivariate logistic regression analysis showed that body mass index (BMI) ( OR=1.125, 95% CI: 1.086-1.165) was positively correlated with HUA, while female ( OR=0.241, 95% CI: 0.182-0.320), total score of cardiovascular health behaviors (compared to lower level, intermediate level: OR=0.186, 95% CI: 0.127-0.273, high level: OR=0.038, 95% CI: 0.020-0.072), and number of achieved healthy behavior items ( OR=0.757, 95% CI: 0.621-0.922) were negatively correlated with HUA. Conclusions:The underage group has the highest number of people who meet the smoking, dietary, and sleep standards, the young and elderly group has the highest number of people who meet the exercise standards, and the elderly group has the highest total score for ideal cardiovascular health behaviors. There is a positive correlation between BMI and HUA, while there is a negative correlation of HUA with female, the total score and number of achieved items of cardiovascular health behaviors.

Objective To explore the relationship between oxygen saturation (SpO2) and cognitive function in older adults from longevity areas in China. Methods A total of 2 285 participants aged ≥65 years according to the 2012 Chinese Longitudinal Healthy Longevity Survey were included in this study. Among them, 1 739 participants aged 65-99 years were randomly selected, and 546 participants aged≥100 years were totally involved. A standardized questionaire was used to collect the information of demographic characteristics, life styles, disease history, etc. Cognitive function was evaluated using the Mini Mental State Examination Scale. Arterial oxygen saturation and heart rate were measured by pulse oximetry. Differences in cognitive function between the low SpO2 group (<0.94) and normal SpO2 group (≥0.94) were analyzed, and logistic regression models were used to analyze the relationship between SpO2 and cognitive function. Results The total score of cognitive function was 22.6 ± 9.7 for the 1 922 participants in the normal SpO2 group, and 18.8 ± 11.0 for the 363 participants in the low SpO2 group (t=6.11, P<0.001). The proportion of cognitive impairment in the low SpO2 group was 36.6% (n=133), and 22.9% (n=441) in the normal SpO2 group (χ2=30.44, P<0.001). Results from stepwise logistic regression analysis showed that the risk of cognitive impairment increased with each year of increased age (OR 1.07;(95%CI:1.05-1.09), P<0.001). Low SpO2, vision disorders, impaired activities of daily living, dyslipidemia, unmarried status, and lack of exercise were also associated with increased risk of cognitive impairment (OR 1.64; (95% CI: 1.11-2.43), OR 1.73; (95% CI: 1.27-2.35), OR 3.54; (95% CI: 2.62-4.79), OR 1.38; (95% CI: 1.02-1.86), OR 2.05;(95%CI:1.34-3.13), OR 1.83;(95%CI:1.13-2.97), respectively, P<0.05). Stratified analysis by age group showed that the association between SpO2 and cognitive impairment was most significant in participants aged ≥90 years (OR 1.58; (95% CI: 1.09-2.28), P=0.016). Conclusion Low oxygen saturation was associated with higher risk of cognitive impairment in our population of elderly adults.

Objective:To analyze the differences in whole blood selenium (Se), zinc (Zn), copper (Cu), magnesium (Mg), calcium (Ca), and iron (Fe) levels of rural older adults among areas with different soil selenium levels, and explore the main factors associated with the six nutrient elements status, so as to provide a basis for further evaluating the health risks of people in areas with different soil selenium levels.Methods:Four administrative villages were randomly selected from the Se-deficient (soil Se content < 0.175 mg/kg), Se-sufficient (soil Se content 0.175 - < 0.400 mg/kg), Se-rich (soil Se content 0.400 - < 3.000 mg/kg) and Se-excessive (soil Se content ≥3.000 mg/kg) areas, respectively, in Enshi Tujia and Miao Autonomous Prefecture (Enshi Prefecture) of Hubei Province in 2017 - 2018. And 100 elderly people aged 60 years or older (half male and half female) were randomly selected as the survey subjects in each servey site. The basic information such as general demography and lifestyle was collected through face-to-face questionnaires. Physical examination was performed and fasting venous blood was collected in the morning. The contents of blood Se, Zn, Cu, Mg, Ca, and Fe were determined by inductively coupled plasma mass spectrometry. The main factors associated with the six nutrient elements status were analyzed.Results:A total of 416 subjects were included, including 208 males and 208 females, whose average age was (72.43 ± 5.25) years, and body mass index (BMI) was (22.67 ± 3.49) kg/m 2. There were significant differences of blood Se, Zn, Cu, Mg, Ca and Fe levels between the areas with different Se levels ( Z/F = 288.30, 3.24, 14.81, 29.14, 131.28, 3.37, P < 0.05). Compared with Se-deficient and Se-sufficient areas, blood Se level was higher in Se-rich and Se-excessive areas and blood Zn level was lower in Se-excessive area ( P < 0.05); compared with Se-sufficient area, blood Cu level was lower in Se-deficient, Se-rich and Se-excessive areas, but blood Mg and Ca levels were higher ( P < 0.05), and the blood Fe level was lower in Se-excessive area ( P < 0.05). There were significant differences in the deficiency rates of Se, Zn, Cu, Mg, Ca and Fe among the elderly in different Se level areas (χ 2 = 140.83, 15.39, 31.90, 17.49, 157.60, 30.33, P < 0.01). There were significant differences in blood Zn, Cu, Ca and Fe levels between two gender groups ( P < 0.05); the blood Zn and Fe levels of the smokers were higher than those of the non-smokers, and the blood Cu level was lower than that of the non-smokers ( P < 0.05); the blood Zn and Fe levels of the drinkers were higher than those of the non-drinkers ( P < 0.05). Conclusions:The levels of six nutrient elements in the whole blood of the elderly in areas with different soil Se levels are different. To assess the health risks of the population in areas with different soil Se levels, it is necessary to consider the levels of multiple nutrient elements at the same time.
