Objective To explore the relationship between body mass index (BMI) and frailty among community aged people. Methods A total of 1571 aged people in two communities in Zhengzhou, Henan, China were recruited by convenience sampling method. They were divided into normal group, overweight group and obesity group according to BMI, and were assessed with Fried Frailty Criteria. Results The rates of overweight and obesity were 38.6%and 10.9%, respectively. There was significant difference in the level of frailty among dif-ferent groups (χ2=86.659, P<0.001). Multivariate Logistic regression analysis showed that overweight and obesity were independent risk fac-tors of pre-frailty (P<0.05), and obesity was the independent risk factor of frailty (P<0.05). Conclusion The prevalence of overweight and obesity was higher in community aged people in Zhengzhou, and normal BMI was important to postpone the process of frailty.

With the rapid increase of the number of cardiovascular disease patients in China, and the popular trend of cardiovascular disease risk factors is becoming more and more obvious, the control of risk factors for cardiovascular disease has become an important public health problem as well as a great challenge to social and economic development. Recent studies show that resistance training plays a positive impact on the control of risk factors for cardiovascular disease. This article reviewed the related literature in recent years for the resistance training control risk factors of the cardiovascular disease, and stated the precautions and challenges during the process of the implementation of resistance training in order to provide new clues to the research and practice for control the risk factors of cardiovascular disease .

At present, the suitable sports rehabilitation methods for frail old people mainly include endurance training, resistance train-ing and comprehensive functional training, while comprehensive functional training includes aerobic exercise and anaerobic exercise, and is suitable for the frail elderly to do exercise at home, which is more conducive to further large-scale promotion. In addition, long-term low and medium intensity exercise can improve the balance ability of the elderly, prevent them from fall, improve the physiological function, and ef-fectively regulate muscle potential;while, the high intensity exercise has greater risk for older people. This article introduced the types and effects of exercise in order to provide reference basis for frail old people in China.

RNA-Sequencing (RNA-Seq) is a newly-developed method in transcriptome research, it can afford more accurate transcription information and be more quickly by using Next-generation Sequencing (NGS) technology. RNA-Seq has been widely used in various biological fields. Genuine traditional Chinese medicines (TCM), with good quality and therapeutic effect, were always praised highly and used by famous physicians. The geo-herbalism formation of TCM is based on the product of the gene expression at specific space and time. So it has been a research hotspot to analyze the mechanism of biosynthesis through RNA-Seq in the study on the secondary metabolism of medicinal plant. This article mainly illustrates the RNA-Seq and its advantages, it also discusses the potential application in genuine TCM, and it can provide useful information for other researchers.

Sarcopenia is common in chronic heart failure. The pathogenesis of chronic heart failure-related sarcopenia is complex and diverse. Resistance training, as the main intervention for chronic heart failure-related sarcopenia, is widely applicated as effective and safe therapy.

Objective To analyze the relationship between knowledge on cardiovascular disease prevention and ideal cardiovascular health behaviors and factors in community elderly. Methods From December, 2015 to May, 2016, totally 400 elderly in communities with-out overt cardiovascular disease were conveniently sampled. The level of knowledge on cardiovascular disease prevention was measured by self-designed cardiovascular disease prevention questionnaire. And each of the ideal cardiovascular health components was collected. Re-sults A total of 390 responses were valid. 13.85%community elderly were with high level of the knowledge. There were significant differ-ences in the distribution of cardiovascular health indexes among various leves of the knowledge groups (χ2>9.974, P<0.05), except choles-terol (P>0.05). The level of the knowledge was positively correlated with the scores of cardiovascular health behaviors and health factors (r>0.354, P<0.01). The cardiovascular health score, health behaviors score, health factors score and number of ideal cardiovascular health in-dexes were significantly different among various levels of the knowledge groups (F>8.961, P<0.001). Conclusion The level of knowledge on cardiovascular disease prevention was positively correlated with cardiovascular health behavior and health factors. The scores of cardio-vascular health score, health behaviors score and health factors increased with the improvement of knowledge on cardiovascular disease pre-vention.

Objective:To explore the practical effect of nursing research group model in a training program for clinical nurses′ scientific research ability.Methods:From August 2020 to July 2021, 30 clinical nurses from the Fifth Affiliated Hospital of Sun Yat-sen University were trained by case teaching mode through the construction of a complete nursing scientific research training course system with the nursing research group as the carrier. The scores of nursing scientific research ability of clinical nurses before and after the training were compared, and the evaluation of teaching effect and the output of scientific research results were analyzed.Results:After the training, the total scores of clinical nurses′ scientific research ability, problem discovery ability, literature reading ability, scientific research design ability, data processing ability, scientific research practice ability and thesis writing ability were 78.33 ± 7.48, 8.83 ± 1.42, 14.47 ± 1.22, 13.27 ± 1.36, 11.07 ± 1.60, 14.73 ± 1.28, 15.97 ± 1.35 respectively. The scores were significantly higher than those before the training (59.00 ± 7.44, 6.53 ± 1.22, 11.80 ± 1.37, 9.53 ± 1.31, 8.10 ± 1.37, 11.30 ± 1.34, 11.73 ± 1.46), and the differences were statistically significant ( t values were -52.80 - -21.14, all P<0.05). The proportion of clinical nurses who believed that the training with nursing research group as the carrier could improve learning attitude, enhance clinical comprehensive ability and promote professional development was ≥90%. After the training, 8 papers were published, 3 projects were approved and 2 patents were approved, which were significantly higher than those before the training (2, 1 and 0), and the total scientific research and innovation achievements increased by 333.33% (10/3) compared with those before the training. Conclusions:Scientific research training with nursing research group as the carrier can improve the scientific research ability of clinical nurses and improve their innovative thinking.

Objective:To investigate the current status of emotional intelligence of standardized training nurses and explore the influencing factors.Methods:A total of 312 standardized training nurses from the Fifth Affiliated Hospital of Sun Yat-sen University and the First Affiliated Hospital of Nanchang University were investigated from May to June 2020 with general information questionnaire and Nurses′ Emotional Intelligence Scale, and analyze the influencing factors of nurses′ emotional intelligence during the standar dized training period.Results:The total score of standardized training nurses′ emotional intelligence was (59.01 ± 8.24), the scoring rate was 73.76%, and the total average score of items was (3.69 ± 0.52). The average scores of the four dimensions from low to high were: self emotion assessment (3.86 ± 0.66), self emotion management (3.67 ± 0.71), self emotion application (3.64 ± 0.67) and emotion assessment of others (3.58 ± 0.65). Multiple linear regression analysis showed that political outlook, whether it was an only child, and training time and willingness to engage in nursing work for a long time were the main influencing factors of standardized training nurses′ emotional intelligence, accounting for 32.6% of the variance.Conclusions:The emotional intelligence of standardized training nurses is at the medium level, which needs to be further improved. Hospital managers need to carry out positive intervention combined with relevant influencing factors to cultivate more excellent nursing talents for clinical practice.

Objective:To investigate the current status of emotional labor of nurses in standardized training period, and to analyze the relationship between emotional labor and emotional intelligence.Methods:From May to June 2020, 312 nurses in the standardized training period were selected as the research objects, which were investigated with general information questionnaire, Emotional Labor Scale and Emotional Intelligence Scale.Results:The total score of standardized training nurses' emotional labor was (52.27±10.18) points, and the total average score of items was (3.73±0.73) points. The average scores of the three dimensions from high to low: deep acting (4.62±0.86) points, expression of genuine emotion (3.62±0.99) points and surface acting (3.42±0.95) points. There was a correlation between emotional intelligence and emotional labor. Multiple linear regression analysis showed that the emotional evaluation of others ( β value was -0.189, P<0.05) ( β value was -0.255, P<0.01). Self emotional assessment ( β value was 0.297, P<0.01) ( β value was 0.177, P<0.05). Self emotional assessment ( β value was 0.269, P<0.05), which had a positive predictive effect on emotional expression requirements. Conclusions:The emotional labor of nurses in standardized training period is at the medium level, and the deep acting score is the highest between three dimensions. Hospital managers could promote nurses to use appropriate emotional labor strategies by strengthening the cultivation of emotional intelligence during standardized training period.

OBJECTIVE: To compare the image quality of three-dimensional time-of-flight (TOF) magnetic resonance angiography (MRA) with sparse undersampling and iterative reconstruction (sparse TOF) with that of conventional TOF MRA. MATERIALS AND METHODS: This study included 56 patients who had undergone sparse TOF MRA for intracranial artery evaluation on a 3T MR scanner. Conventional TOF MRA scans were also acquired from 29 patients with matched acquisition times and another 27 patients with matched scanning parameters. The image quality was scored using a five-point scale based on the delineation of arterial vessel segments, artifacts, overall vessel visualization, and overall image quality by two radiologists independently, and the data were analyzed using the non-parametric Wilcoxon signed-rank test. Contrast ratios (CRs) of vessels were compared using the paired t test. Interobserver agreement was calculated using the kappa test. RESULTS: Compared with conventional TOF at the same spatial resolution, sparse TOF with an acceleration factor of 3.5 could reduce acquisition time by 40% and showed comparable image quality. In addition, when compared with conventional TOF with the same acquisition time, sparse TOF with an acceleration factor of 5 could also achieve higher spatial resolution, better delineation of vessel segments, fewer artifacts, higher image quality, and a higher CR (p < 0.05). Good-to-excellent interobserver agreement (κ: 0.65–1.00) was obtained between the two radiologists. CONCLUSION: Compared with conventional TOF, sparse TOF can achieve equivalent image quality in a reduced duration. Furthermore, using the same acquisition time, sparse TOF could improve the delineation of vessels and decrease image artifacts.
