Objective To explore the effects of aerobic exercise and resistance training on center arterial blood pressure.Methods Fifteen healthy men who had not practiced aerobic exercise or resistance training within the previous 6 months were enrolled in this study.A self-matched pairs design was adopted.All of the subjects performed moderate intensity aerobic exercise,for 30 min initially,and after 2 weeks,performed resistance training at 60％ of their l-repeat maximum effort (1-RM).Their central aortic systolic blood pressure (CSBP) before and after aerobic exercise and resistance training were measured and compared,respectively.The changes in CSBP and an augmentation index (AI) of radial artery and relative blood pressure were compared between the two interventions.Results CSBP decreased significantly after both sorts of training.The two types of training showed no significant difference in their effects on CSBP.However,after a 20 min recovery,systolic blood pressure and pulse pressure were significantly lower after aerobic exercise than after resistance training.The significant difference persisted after 20 min and 40 min of re-covery.The AI of the radial artery was also significantly lower 5 min after aerobic exercise than after resistance train-ing.Conclusions After moderate aerobic exercise and resistance training,CBSP,AI and systolic pressure all display favorable changes.However,moderate intensity aerobic exercise provides the better effect in improving blood pressure.

Objective:To investigate the expression of miR-151a-3p in peripheral blood mononuclear cells (PBMCs) of children with lupus nephritis (LN) and its correlation with activity and vascular damage.Methods:A total of 87 children with LN admitted in Hainan Women and Children′s Medical Center from January 2016 to March 2019 were enrolled, including 16 cases of type Ⅱ, 14 cases of type Ⅲ, 34 cases of type Ⅳ, 17 cases of type Ⅴ and 6 cases of type Ⅵ.Besides, additional 40 children with normal physical examination were selected as the healthy control group.The 87 children with LN were divided into the LN stable group (31 cases) and LN active group (56 cases) by using systemic lupus erythematosus disease activity index (SLEDAI) scores.According to different proportions of the medium membrane, the patients were classified into the mild group (25 cases), moderate group (34 cases) and severe group (28 cases). Real time quantitative PCR (qPCR) was used to detect the expression level of miR-151a-3p in PBMCs of each group.The correlation of the expression level of miR-151a-3p in PBMCs of LN children with the SLEDAI score and renal interstitial damage score was studied by Pearson correlation analysis. Results:The expression levels of miR-151a-3p in the LN group, LN active group and LN stable group (0.47 ± 0.06, 0.30 ± 0.04, and 0.75±0.12, respectively) were significantly lower than that in the healthy control group (1.62±0.35) (all P<0.01), and the expression level of miR-151a-3p in the LN active group (0.30±0.04) was significantly lower than that in the LN stable group (0.75±0.12) ( P< 0.01). The SLEDAI score [(14.35±4.60) points vs.(8.25±2.24) points] and renal interstitial damage score [(52.70±6.30) points vs.(34.80±4.10) points] in the LN active group were significantly higher than those in the LN stable group (all P<0.01). The expression levels of miR-151a-3p (0.18±0.02, 0.41±0.05 vs.0.83±0.16) in type Ⅴ-Ⅵ and type Ⅳ groups were significantly lower than that in the type Ⅱ-Ⅲ group (all P<0.01). The SLEDAI scores [(16.50±5.28) points, (12.36±3.74) points vs.(6.40±1.70) points] and renal interstitial damage scores [(62.70±7.40) points, (47.20±5.80) points vs.(25.80±3.50) points] in type Ⅴ-Ⅵ and type Ⅳ groups were significantly higher than those in the type Ⅱ-Ⅲ group (all P< 0.01). The expression levels of miR-151a-3p (0.20±0.02, 0.39±0.04, 0.86±0.18 vs.1.62±0.35) in severe, moderate and mild groups were significantly lower than that in the healthy control group (all P<0.01), and the expression level of miR-151a-3p decreased with the aggravation of vascular damage.The SLEDAI scores [(15.20±5.10) points, (12.85±3.90) points vs.(6.70±1.82) points] and renal interstitial damage scores [(57.30±6.80) points, (51.60±6.30) points vs.(27.20±3.60) points] in the severe and moderate groups were significantly higher than those in the mild group (all P<0.01). The expression level of miR-151a-3p in LN children was negatively correlated with the SLEDAI score and renal interstitial damage score ( r=-0.682, -0.627, all P<0.001). Conclusions:The expression level of miR-151a-3p in PBMCs of LN children is significantly decreased.The declined miR-151a-3p level is closely related to disease activity and vascular damage, and may be involved in the occurrence and development of LN.

Objective:To investigate the prognostic value of serum levels of miR-320 in sepsis children complicated with acute kidney injury (AKI).Methods:A total of 158 sepsis children with complicated with AKI who were admitted to Hainan Women and Children′s Medical Center from January 2017 to June 2019 were divided into survival group (105 cases) and death group (53 cases) according to their 28-day survival.Serum levels of miR-320, neutrophil gelatinase associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1) and serum creatinine (Scr) were detected in the two groups.Multivariate Logistic regression was used to analyze the risk factors of death in children with sepsis complicated with AKI.The receiver operating characteristic curve (ROC) was drawn to analyze the value of serum levels of miR-320, NGAL, KIM-1 and Scr in predicting the death of children with sepsis complicated with AKI.The correlation between serum levels of miR-320 and NGAL, KIM-1 and Scr was analyzed using Pearson correlation analysis. Results:The serum levels of miR-320 (1.28±0.47 vs. 0.54±0.12), NGAL [(537.40±48.26) mg/L vs. (285.60±29.40) mg/L], KIM-1 [(26.80±5.72) μg/ L vs. (16.35±3.17) μg/L] and Scr[(573.70±105.46) μmol/L vs. (390.64±74.38) μmol/L] in the death group were significantly higher than those in the survival group (all P<0.001). Multivariate Logistic regression analysis showed that serum levels of miR-320 ( OR=2.280, 95% CI: 1.483-4.380), NGAL ( OR=2.753, 95% CI: 1.826-5.227), KIM-1 ( OR=1.985, 95% CI: 1.274-3.518) and Scr ( OR=1.714, 95% CI: 1.105-2.986) were independent risk factors for death in sepsis children with AKI (all P<0.001). ROC curve analysis showed that the area under the curve (0.952, 95% CI: 0.894-0.990) of serum miR-320, NGAL, KIM-1 and Scr levels combined to predict the death of children with sepsis and AKI was the largest, with a high sensitivity and specificity of 95.8% and 90.6%.Correlation analysis showed that the expression level of serum miR-320 in the death group was positively correlated with NGAL, KIM-1 and Scr ( r=0.874, 0.830, 0.702, all P<0.01). Conclusions:Serum levels of miR-320 are significantly increased in sepsis children with AKI, which is an independent risk factor for death in sepsis children with AKI.The combination of NGAL, KIM-1 and Scr levels has important value in predicting the prognosis of children with AKI.

Objective:To construct acute ST-segment elevation myocardial infarction (STEMI) percutaneous coronary intervention (PCI) by using lipoprotein-associated phospholipase A2 (Lp-PLA2) and D-dimer to fibrinogen ratio (D/F) and other indicators postoperative patient prognosis nomogram model and evaluation of its predictive value.Methods:A total of 291 acute STEMI patients admitted to the BenQ Hospital Affiliated to Nanjing Medical University from January 2017 to January 2020 were retrospectively selected, including but not limited to Lp-PLA2 and D/F, were collected. Receiver operating characteristic (ROC) curve and multivariate Logistic regression were used to analyze the risk factors of death within 90 d after PCI in STEMI patients, and Kaplan-Meier survival curves were drawn to compare the survival of patients in different Lp-PLA2 and D/F groups. The R language software was used to build nomogram model and decision curve.Results:The AUCs of LpPLA2 and D/F for predicting the risk of death from cardiac causes at 90 s after PCI in patients with acute STEMI were 0.896 (95% CI 0.850 to 0.932) and 0.884 (95% CI 0.837 to 0.922), respectively. The values were 59.50 μg/L and 0.46 respectively ( P<0.05); the mortality rates of acute STEMI patients in LpPLA2>59.50 μg/L and D/F>0.46 groups after PCI were higher than those in LpPLA2≤59.50 μg/L group and D/F≤0.46 group ( P<0.05); age (>66 years), left ventricular ejection fraction (LVEF) (≤45%), LpPLA2 (>59.50 μg/L), D/F (>0.46), N-terminal brain natriuretic peptide precursor (>1.55 μg/L) and fasting blood glucose (>7.00 mmol/L) were the risk of death from cardiac causes at 90 d after PCI in patients with acute STEMI ( P<0.05); when the risk thresholds were >0.24, the nomogram model could provide significant additional net clinical benefit. Conclusions:Lp-PLA2 and D/F are closely related to the prognosis of patients with acute STEMI after PCI, and the nomogram model constructed in combination with other clinical indicators can effectively predict the risk of death within 90 d after PCI.

Objective:To analyze the research status of umbrella review by bibliometric methods.Methods:The citation search was performed via Web of Science Core Collection database to obtain studies on umbrella review from inception to December 31, 2021. VOSviewer1.6.16 was used to extract the included authors, countries, institutions and keywords, and generate the cooperative network graph of high-productivity authors, countries, institutions, and clustering graph of high-frequency keywords. CiteSpace5.7.R5W was used to detect burst terms.Results:A total of 755 articles or reviews were included. The quantity of studies had been increasing over time. The United Kingdom was the country with the most published papers (297), and the University of College London was the institution with the most published papers (77). A total of 3 863 authors participated in the umbrella review research, of which Solmi M had the largest number of papers with 28 papers published. The main authors formed three groups, with little cooperation between the groups. Research hotspots focused on chronic diseases such as cardiovascular disease, diabetes, cancer, mental health and its health management. Besides, diabetes, heart failure and Mediterranean diet were the frontier fields.Conclusions:Umbrella review is in the development stage, and the amount of studies is increasing. The United Kingdom is in a leading position in this field. The members of each team work closely together, but there is a lack of cross-team cooperation. Chronic diseases and their management are currently research hotspots and key research contents.
