The radial artery pulse wave contains a wealth of physiological and pathological information about the human body, and non-invasive studies of the radial artery pulse wave can assess arterial vascular elasticity in different age groups.The piezoelectric pulse wave transducers were used to non-invasively acquire radial artery pulse waves at different contact pressures in young and middle-aged and elderly populations. The radial artery waveforms were decomposed using a triangular blood flow model fitting method to obtain forward and reflected waves and calculate reflection parameters. Finally a correlation analysis and regression analysis of the contact pressure Psensor with the reflection parameters was carried out. The results showed that the reflection parameters RM, RI and Rd had a strong negative correlation with Psensor in both types of subjects, and the correlation coefficients and slopes of the regression curves were significantly different between the two types of subjects (P<0.05). Based on the results of this study, excessive contact pressure on the transducer should be avoided when detecting radial artery reflection waves in clinical practice. The results also show that the magnitude of the slope of the regression curve between the reflection parameters and the transducer contact pressure may be a potentially useful indicator for quantifying the elastic properties of the vessel.
ObjectiveTo systematically review the correlation of pSTAT3 overexpression and prognosis in lung cancer patients.MethodsWe searched from PubMed, EMbase, Web of Science, CNKI, VIP and WanFang Data databases to collect relevant studies about the correlation of pSTAT3 overexpression and prognosis in lung cancer patients from inception to November 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.2 software.Results A total of thirteen studies were enrolled. The results of the meta-analysis showed that the overall survival (HR=1.23, 95%CI 1.04 to 1.46, P=0.02) of pSTAT3 overexpression group was shorter than that of low expression group. In terms of clinical prognostic characteristics, pSTAT3 overexpression rate in stage Ⅲ to Ⅳ group was significantly higher than stage Ⅰ to Ⅱ (OR=1.92, 95%CI 1.13 to 3.27, P=0.02). pSTAT3 overexpression rate of lung cancer patients with lymphatic node metastasis was also significantly higher than lung cancer patients without lymphatic node metastasis (OR=1.81, 95%CI 1.20 to 2.72, P=0.004). However, there was no statistical difference of pSTAT3 overexpression between well-moderately differentiation and poorly differentiation group (OR=0.82, 95%CI 0.44 to 1.53, P=0.54).ConclusionpSTAT3 overexpression is associated with poorer overall survival of lung cancer patients, as well as with more and advanced TNM grade and lymph node metastasis. It may be an indicator poor biomarker in lung cancer patients. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusion.
ObjectiveTo explore the correlation between quality of life and social support and anxiety level in children with epilepsy. MethodsA total of 207 children with epilepsy and their parents from March 2023 to December 2023 from Shanghai Children's Hospitalwere selected as the investigation objects, and the children's quality of life scale, Children's perceptive Social support Scale and PROMIS parental Report version anxiety brief form were used to investigate. The correlation between the quality of life of children with epilepsy and the level of social support and anxiety was analyzed. ResultsThe results of univariate analysis showed that the quality of life of children with epilepsy was affected by whether they had siblings and the frequency of onset in the past month (P<0.05). Pearson correlation analysis showed that social support was positively correlated with quality of life (P<0.05). The scores of anxiety and quality of life were negatively correlated (P<0.05). Social support was negatively correlated with anxiety scores (P<0.05). The results of multiple linear regression analysis showed that siblings, social support and anxiety were independent factors affecting the quality of life of children with epilepsy (P<0.05). ConclusionSocial support has a positive effect on the quality of life of children with epilepsy, anxiety level has a negative effect on the quality of life, and social support has a negative effect on anxiety. Therefore, clinical psychological support should be strengthened for children with epilepsy, fully mobilize their positive psychological factors, reduce their anxiety and other negative emotions, play a full range of social support, to achieve the goal of improving the quality of life.
ObjectiveTo systematically review the correlation between adenoviral infection and encephalitis in children. MethodsStudies on the correlation between adenoviral infection and encephalitis among children were retrieved in the databases of CHKD, CNKI, WanFang Data, CMCC, PubMed, Ovid, EBSCO, and Science New during 1978-2013. According to our inclusion and exclusion criteria, literature was screened. After data extraction, meta-analysis was conducted using Comprehensive Meta Analysis 2.0. ResultsA total of 18 studies were enrolled. The results of meta-analysis indicated that:the prevalence of infection of human adenovirus in children with encephalitis was p1=10.8% (95%CI 6.5% to 15.2%, P < 0.000 01). The incidence of encephalitis in children with adenoviral infection was p2=31.4% (95%CI 14.1% to 48.6%, P < 0.000 01). The results of two studies showed that, the correlation coefficients between adenoviral infection and encephalitis were OR1=2.22 (95%CI 0.32 to 14.79, P > 0.05), and OR2=1.12 (95%CI 0.14 to 9.10, P > 0.05), respectively, both with no significant difference. In addition, the subgenus B adenoviruses, including type 3 and type 7 were more associated with encephalitis, followed by type 1 and type 2 in subgenus C and type 8 in subgenus D. ConclusionCurrent evidence shows that no correlation exists between adenoviral infection and encephalitis in children. However, the above conclusion needs to be verified by conducting more rationally-designed studies so as to clarify the correlation.
ObjectiveThrough neuropsychological assessment, explore the factors that may cause cognitive impairment in patients with focal epilepsy.MethodsCollected 53 epilepsy patients in outpatients and inpatients of Tianjin Medical University General Hospital from March 2016 to January 2020, including 25 males and 28 females, with an average age of (23.58±13.24) years old, and the course of disease (6.49±7.39), all met the 2017 ILEA diagnostic criteria for focal epilepsy, and there was no history of progressive brain disease or brain surgery. Carry out relevant cognitive assessments for the enrolled patients, use SPSS statistical software to conduct Spearman correlation analysis on the cognitive functions of the study subjects, and further analyze the related factors of cognition through Logistic regression analysis to clarify the factors related to cognition whether it may be a risk factor for cognitive impairment in patients with focal epilepsy.Results Spearman correlation analysis showed that the FIQ of patients with focal epilepsy was related to education level, age of onset, seizure pattern, total number of seizures, AEDs and EEG interval discharge side (P<0.05). Binary Logistic regression analysis shows that among all cognitive-related factors, only the number of AEDs (P=0.003) and EEG interval discharge (P=0.013) are the risk of cognitive impairment in patients with focal epilepsy factor.ConclusionIn the clinical treatment of epilepsy, seizures should be actively controlled, but the types of drugs should be minimized. When there are more than 3 kinds of drugs, surgical treatment or other non-surgical treatments can be considered. At the same time, the EEG should be reviewed regularly to understand the changes in epileptiform discharges between episodes.
Objective To investigate the relationship between the red blood cell distribution width (RDW) and the severity of community-acquired pneumonia (CAP). Methods The clinical data of 285 adult patients with CAP admitted from November 2014 to August of 2017 were analyzed retrospectively. The severity of CAP was evaluated by pneumonia severity index (PSI) score. Meanwhile, 60 cases with qualified medical examination were collected as a healthy control group. The distributions of PSI score, RDW, procalcitonin (PCT), C-reactive protein (CRP) and neutrophil percentage (NEU%) were described in the patients with different risk degree. The correlation analysis of various indicators were analyzed by Spearman correlation. The threshold of RDW(%) was calculated through the construction of the general linear regression equation. The risk factors of PSI score were analyzed with multiple linear regression. Results The higher the risk stratification, the higher the distribution of PSI scores, RDW, PCT, CRP and NEU% were. RDW was positively correlated with PCT, CRP, and NEU% (r values were 0.417, 0.252, 0.318, respectively, P<0.05). PSI score was positively correlated with RDW, PCT, CRP, and NEU% (r values were 0.537,0.598, 0.557, 0.482, respectively, P<0.05). RDW was positively correlated with PSI score (r=0.537, P<0.05). The thresholds of RDW(%) were 14.514 and 19.041. Multiple linear regression showed that RDW, PCT, CRP and NEU% were all influential factors of PSI scores and explained 46.9% of the total mutation rate. Conclusion RDW is correlated with the severity of CAP, and can predict the severity of CAP.
ObjectiveTo explore the changes of plasma prealbumin (PA), homocysteine (Hcy) and high-sensitivity C-reactive protein (hs-CRP) levels before and after treatment in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), and analyze the correlation of PA and Hcy with hs-CRP and body mass index (BMI).MethodsA total of 132 hospitalized AECOPD patients with GOLD lung function as grade III-IV were recruited as an experimental group and 45 healthy subjects as a control group. The levels of plasma PA, Hcy and hs-CRP were measured by automatic biochemical analyzer, and the main indexes of pulmonary function were determined in all subjects.ResultsCompared with the control group, the level of plasma PA before and after treatment in the experimental group decreased significantly [(146.49±36.53) mg/L and (219.60±41.29) mg/L vs. (269.48±42.63) mg/L], the level of plasma Hcy before and after treatment increased significantly [(16.44±5.21) μmol/L and (12.61±4.56) μmol /L vs. (10.13±3.25) μmol/L], and the levels of plasma hs-CRP before and after treatment increased significantly [(45.24±29.94) mg/L and (7.71±3.41) mg/L vs. (5.01±1.52) mg/L] (all P<0.05). The levels of plasma PA, Hcy and hs-CRP after treatment were significantly better than before treatment in the experimental group (allP<0.01). The plasma PA values before and after treatment were negatively correlated with the level of hs-CRP before and after treatment, and positively correlated with BMI (bothP<0.05).ConclusionsThe levels of plasma PA, Hcy and hs-CRP are significantly different before and after the treatment in AECOPD patients and the healthy controls. PA is negatively correlated with hs-CRP and positively correlated with BMI. The detection of plasma PA and Hcy can help to determine the condition and efficacy of patients with COPD, and PA can reflect the level of inflammation and nutritional status to a certain extent.
ObjectiveTo investigate the relationship between the red blood cell distribution width (RDW) and the severity of acute exacerbation of bronchiectasis in elderly patients.MethodsThe clinical data of 216 elderly patients with acute exacerbation of bronchiectasis admitted from January 2015 to October of 2018 were analyzed retrospectively. The severity of acute exacerbation of bronchiectasis in the elderly was evaluated by bronchiectasis severity index (BSI) score. Meanwhile, 50 elderly people receiving qualified medical examination were collected as a healthy control group in the same period. The distributions of BSI score, RDW, procalcitonin (PCT), neutrophil percentage (NEU%) and C-reactive protein (CRP) were described in the patients with different risk degree. The severity of acute exacerbation of bronchiectasis in the elderly was evaluated by BSI. The patients were divided into three groups by BSI score: a low risk group, a middle risk group, and a high risk group. The indexes were described including the distribution of stratified BSI score, RDW, PCT, NEU%, CRP at different risk levels. The correlation of each index was analyzed by Spearman correlation. The threshold value of RDW was calculated by general linear regression, and the influencing factors of BSI score were analyzed by multivariate linear regression analysis.ResultsThe higher the risk stratification, the higher the BSI score, RDW, PCT, NEU% and CRP were. RDW was positively correlated with PCT, NEU% and CRP (r values were 0.425, 0.311, 0.177, respectively, P<0.05). BSI score was positively correlated with RDW, PCT, NEU%, and CRP (r values were 0.425, 0.394, 0.650, 0.578, respectively, P<0.05). RDW was positively correlated with PSI score (r=0.425, P<0.05). The thresholds of RDW were 11.45% and 14.03%. Multiple linear regression showed that RDW, PCT, NEU% and CRP were all influential factors of BSI score and explained 52.3% of the total mutation rate.ConclusionRDW is related to the severity of acute exacerbation of bronchiectasis in the elderly, and can predict the severity of acute exacerbation of bronchiectasis in the elderly.
Objective To explore the effect of smoking on pulmonary function parameters of male patients with chronic obstructive pulmonary disease (COPD) and to analyze the correlation between smoking and pulmonary function parameters. Methods From January 2014 to October 2015, the pulmonary function parameters of 223 male outpatients or hospitalized patients with COPD in the Department of Respiratory Medicine were retrospectively analyzed by using SPSS 17.0 software. The patients were randomly divided into smoking group (n=98), smoking cessation group (n=82) and non-smoking group (n=43). Results Various degrees of damage or abnormality of lung capacity, ventilatory function, gas exchange function and airway resistance (Raw) existed in the patients with COPD. Compared with smoking cessation group and non-smoking group, residual volume/ total lung capacity (RV/TLC) and Raw were significantly higher (P< 0.05), maximum ventilatory volume, ventilation reserve percent, forced vital capacity, the percent of first second forced expiratory volume compared its predicted value (FEV1%pred), maximum mid-expiratory flow (MMEF), forced expiratory flow 50%, forced expiratory flow 75% and diffusing capacity of carbon monoxide were significantly lower (P<0.05) in the smoking group. There was a negative relationship between MMEF, FEV1%pred and smoking index (r=–0.352, –0.381, P<0.05), and a positive relationship between Raw, RV/TLC and smoking index (r=0.403, 0.378, P<0.05). Conclusions Most of the male COPD patients smoke or used to smoke. Smoking leads to ventilation and gas exchange function decrease, small airway limitation aggravation, airway resistance and emphysema degree increase in COPD patients. Smoking index has a negative relationship with MMEF, FEV1%pred and a positive relationship with Raw and RV/TLC.
Objective To explore the correlation between metabolic syndrome and renal function in physical examination population. Methods The data of individual physical examination in West China Hospital from March to April 2015 was collected. Body mass index (BMI), glomerular filtration rate (GFR) were calculated, and the correlation between metabolic syndrome and renal function was analyzed by using SPSS 16.0 software. Results A total of 10 098 individuals were included, of which 1 110 were MS patients were included. The results of analysis showed that, the levels of uric acid, cholesterol, urea and creatinine in MS group were significantly higher than those in non-MS group, and the level of GFR was significantly lower than that in non-MS group (P < 0.05). Renal function in patients with abnormal systolic blood pressure, diastolic blood pressure, fasting blood glucose (FBG), low density lipoprotein, total cholesterol, triglycerides, uric acid index were significantly higher than those in normal renal function group, and high density lipoprotein cholesterol was significantly lower than that of normal renal function group (P < 0.01). Conclusion Elevated levels of BMI, blood pressure, glucose, uric acid are correlated with the decrease of GFR, and metabolic syndrome is an important risk factor of renal dysfunction.
