Objective:To investigate the risk factors and prognosis of mitral regurgitation (MR) in patients with chronic kidney disease (CKD).Methods:Clinical data were collected from CKD patients who were hospitalized at the Department of Nephrology, Xuanwu Hospital, Capital Medical University, from January 1, 2018, to December 31, 2019, and underwent echocardiography. Patients were followed up until November 1, 2021, with the endpoint being all-cause mortality.Logistic regression was used to analyze the risk factors of MR in CKD patients. Kaplan-Meier survival analysis was performed to plot the survival curve, with the Log-rank test comparing the survival rate. Multivariate Cox regression analysis was used to identify the risk factors of death in CKD patients.Results:It was a retrospective single-center study. A total of 555 CKD patients were included, with 262 patients developing MR. Of whom, 212 patients had mild MR (80.9%), 44 patients had modreate MR (16.8%), 6 patients had severe MR (2.3%). The prevalence of MR among patients with CKD stages 1 to 5 was 21.9%, 33.0%, 45.9%, 51.9%, and 64.6%, and the prevalence of moderate to severe MR was 0, 5.6%, 7.4%, 10.1%, and 15.9%. Multivariate logistic regression analysis revealed that male sex ( OR=1.579, 95% CI 1.008-2.476, P=0.046), presence of chronic heart disease ( OR=2.263, 95% CI 1.398-3.662, P=0.001), CKD stage 4-5 (with CKD stage 1-3 as reference, OR=1.744, 95% CI 1.007-3.019, P=0.047), and decreasing hemoglobin levels ( OR=0.985, 95% CI 0.975-0.996, P=0.006) were the associated factors for MR in CKD patients. Kaplan-Meier survival analysis indicated higher all-cause mortality (Log-rank, χ2=8.094, P=0.004) in the MR group compared to the non-MR group. Multivariate Cox regression analysis showed that increasing age ( HR=1.072, 95% CI 1.042-1.104, P<0.001), elevating blood phosphorus ( HR=2.782, 95% CI 1.122-6.895, P=0.027), MR ( HR=1.962, 95% CI 1.002-3.839, P=0.049) and decreasing albumin ( HR=0.927, 95% CI 0.886-0.970, P=0.001) were independent associated factors for all-cause death in CKD patients. Conclusions:The overall prevalence of MR and the prevalence of moderate to severe MR are increasing with the progression of CKD. Male sex, presence of chronic heart disease, CKD stage 4-5 and decreasing hemoglobin levels are risk factors for MR in CKD patients. MR is an independent risk factor for all-cause mortality in CKD patients.

Objective? To expLore the effects of diaLectic nursing-oriented hybrid teaching modeL in pediatric nursing teaching in traditionaL Chinese medicine (TCM). Methods? TotaLLy 113 nursing students from 2 cLasses (midwifery) admitted in 2015 in the SchooL of Nursing, Nanjing University of Chinese Medicine were seLected by convenient sampLing. ALL the subjects were femaLe. The 2 cLasses were divided into the observation group (n=58) or the controL group (n=55) by coin tossing. Nursing students in the controL group received traditionaL teaching, whiLe nursing students in the observation group were taught with the diaLectic nursing-oriented hybrid teaching modeL. At the end of the course, the objective structured cLinicaL examination (OSCE) was used to evaLuate their diaLectic nursing abiLity; and the SeLf-Rating ScaLe of SeLf-Directed Learning (SRSSDL) was used to evaLuate their seLf-directed Learning abiLity. ResuLts? At the end of the course, the totaL score of diaLectic nursing and scores of various dimensions of the observation group were higher than those of the controL group (P＞ 0.05). The totaL score of seLf-directed Learning abiLity and scores of Learning awareness, Learning behavior, Learning strategy and interpersonaL skiLLs of the observation group were higher than those of the controL group (P＜0.05). ConcLusions? The hybrid teaching modeL in TCM pediatric nursing teaching in universities of Chinese medicine can enhance nursing students' diaLectic nursing abiLity, heLp to cuLtivate their seLf-directed Learning abiLity and achieve the best teaching resuLts.

Objective To systematically review the correlation between birth weight and blood pressure of child and adolescent, and provide a theoretical basis for the etiologic research and the prevention for hypertension of child and adolescent.Methods Comprehensive electronic searches of Chinese Web of Knowledge (CNKI), Wang Fang, Wei Pu (VIP), PubMed and Web of Science were conducted to identify any study reporting the correlation of birth weight and blood pressure of child and adolescent.SPSS 13.0 software was used to convert the data.Meta-analysis was conducted with STATA 12.0 software.Results Thirty four researches were included in this study.The results of meta-analysis showed that low birth weight children or adolescents had a higher risk of hypertension with a significant difference compared to the group which birth weight greater than 2 500 g (OR =1.20;95％ CI:1.09-1.33;P ＜ 0.01).Its systolic blood pressure and diastolic blood pressure was on the high side.In addition, it showed that no significant differences were found between hypertension and high birth weight (OR =1.03;95％ CI:0.89-1.18;P ＞ 0.05).But its systolic blood pressure and diastolic blood pressure was on the high side too.Conclusions Abnormal birth weight is probably a risk factor of child and adolescent high blood pressure.Low birth weight has greater influence on blood pressure of children and adolescents.It can be detected early to prevent abnormal birth weight and child hypertension.

Metabolic syndrome has become a global epidemic that adversely affects human health. Both genetic and environmental factors contribute to the pathogenesis of metabolic disorders; however, the mechanisms that integrate these cues to regulate metabolic physiology and the development of metabolic disorders remain incompletely defined. Emerging evidence suggests that SWI/SNF chromatin-remodeling complexes are critical for directing metabolic reprogramming and adaptation in response to nutritional and other physiological signals. The ATP-dependent SWI/SNF chromatin-remodeling complexes comprise up to 11 subunits, among which the BAF60 subunit serves as a key link between the core complexes and specific transcriptional factors. The BAF60 subunit has three members, BAF60a, b, and c. The distinct tissue distribution patterns and regulatory mechanisms of BAF60 proteins confer each isoform with specialized functions in different metabolic cell types. In this review, we summarize the emerging roles and mechanisms of BAF60 proteins in the regulation of nutrient sensing and energy metabolism under physiological and disease conditions.
