Objective To explore whether the PDA patients in the early stage of Eisenmenger syndrome can accept interventional surgery. Methods Three patients were choose from the “National Multicenter Prospective Registration Study on Pulmonary Artery Hypertension”, Clinical assessment, as well as examinations and registrations associated with PAH, was conducted in accordance with relevant provisions of the registration study within 1 wk prior to surgery. The way of the interventional treatment were right heart catheterization and pulmonary vasodilator testing (a capsule of iloprost solution for inhalation), and measurement of the pulmonary arterial pressure, descending aortic pressure, ratio of pulmonary to systemic blood flow, ratio of pulmonary to systemic blood pressure, pulmonary capillary wedge pressure [mean≤15 mmHg(1 mmHg=0.133 kPa)], before and after testing. After clear the results of pulmonary vasodilator test all patients underwent transcatheter closure testing, if it was positive,the amplatzer was released if her family members’ approved;Conversely, the amplatzer was quickly withdrawn with negative results, and symptomatic treatment was conducted based on the patient’s clinical symptoms. Results The first cases pulmonary vasodilator test was negative, but positive in transcatheter closure testing. Satisfaction immediate effect of surgery, and the occluder was released with her family members’ approval. patients of Example 2 and Example 3 were negative in pulmonary vasodilator testing and transcatheter closure testing, can not released the occluder. Conclusions Some Patents Ductus Arteriosus (PDA) patients in early stage of Eisenmenger syndrome is feasible to accept interventional therapy , try plugging test is may be an important indicator of prognostic assessment.

This study was aimed to distinguish Leonurus japonicus samples produced from different regions and growth environments in Sichuan by electronic nose. The sensor response value of odors of Leonurus japonicus sam-ples were obtained through electronic nose. Principal component analysis (PCA) and discriminant factor analysis (DFA) were used to combine the optimum feature parameters. The results showed that the PCA distinguish index was 82, and the DFA comprehensive classification rate was 97.96% among samples from different regions. The PCA distin-guish index was 84, and the DFA comprehensive classification rate was 100% among samples from different growth environments. The distinguishment and differentiation were effective. It was concluded that electronic nose can be ap-plied to identify the origin and growth environment of Leonurus japonicus from Sichuan to provided reference for odor differentiation.

Objective To investigate the feasibility of the simultaneous measurement of right ventricular pressure-volume loops by cardiac catheterization and 2D electrocardiogram. Methods Patients referred for pulmonary hypertension underwent right heart catheterization in our hospital between June 1st, 2015 and June 1st, 2017 are to be enrolled in this study. The right ventricular volume was measured simultaneously by catheter and electrocardiogram. The pressure-volume loops were constructed by the parameters of the pressure and volume in the same cardiac cycle. Results The study completed in four cases and their pressure-volume loops were drawn. The obtained images were irregular and there was no relationship among them. As a result, the construction was a failure. Conclusions The construction of the right ventricular pressure-volume loops of pulmonary hypertension patients by simultaneous catheterization and 2D electrocardiogram is difficult to overcome the technology defects.

OBJECTIVETo study the function of zinc in preventing human sperm from being damaged by sodium nitroprusside (SNP), an external NO donor.

METHODSAnalyses were made of the function of zinc in protecting sperm from being influenced by SNP in such aspects as sperm motility, head-tail connection and the breakage of sperm DNA chain by using phase-contrast microscope and single cell gel electrophoresis (SCGE).

RESULTSSperm motility was obviously inhibited by SNP. The percentage of comet cells increased significantly but the stability of sperm head-tail connection decreased. Zinc could promote sperm motility, protect the DNA chain and prevent the sperm head-tail connection from breaking.

CONCLUSIONZinc can protect sperm from being damaged by NO. Its mechanism may be related to the mercaptol group of sperm chromatin.

ObjectiveTo explore the effects of dance intervention on cognitive function in children and clarify the design variables of dance intervention protocol. MethodsLiteratures about effects of dance intervention on cognitive function in children were searched in PubMed, Web of Science, EBSCO, Cochrane library, CNKI, VIP and Wanfang Data, with publication dates ranging from inception to June 1, 2022. They were screened and extracted authors, countries, years, samples, study designs, interventions, measurement instruments and outcomes. The Physiotherapy Evidence Database (PEDro) scale was used to assess the methodological quality of included literature. ResultsTen articles were enrolled, which were randomized controlled trial (RCT) and quasi-RCT for typically developing children and developmentally challenged children. The global PEDro score was good. Dance intervention protocol could be divided into four types: dance training course, dance rehabilitation program, dance breaks and aerobic dance. Dance training course was used in the majority of studies. Dance intervention in childhood positively influenced sensorimotor synchronization, attention and executive function. Further studies should pay more attention on the dose-response relationship between dance and cognitive function in children, as well as cognitive load during dance learning. ConclusionWhether short-term or long-term, dance activity is a feasible and effective method to promote sensorimotor synchronization, attention and executive function in children; epecially on the sensorimotor synchronization, attention maintenance time and working memory capacity.

Objective To explore the affect of physical activity on neurocognitive function of overweight children.Methods The literatures about the effect of physical activity on neurocognitive function of overweight children were retrieved with subjected retrieval method in CNKI, VIP, Wanfang database, PubMed, Web of Science, EBSCO databases from January, 2000 to January, 2022. The authors, countries, published years, ages of subjects, research methods, intervention time, measurement tools and measurement indicators were extracted.Results Twelve articles were selected finally. These articles came from United States, Italy, Belgium and China, were mainly published in journals of psychology, clinical medicine, neuroscience, physical education. The study design included randomized controlled trials and pre-post-trial. The mean PEDro score was 6.67. The types of physical activity included fitness, skills and sports activities. The overweight children participating in physical activities could benefit from cognition and brain plasticity. On the cognition, physical activity could improve attention, memory, inhibitory control, working memory and cognitive flexibility. In terms of brain plasticity, physical activity could improve the integrity of brain white matter, increase hippocampal volume, enhance brain activation and brain network connectivity.Conclusion Physical activity is a simple and effective form of exercise. It can improve not only attention, memory, executive function and other cognitive functions, but also brain structure and brain function in overweight children. The mechanism of cognition, the interaction between physical activity and other factors, and the dose-relationship between physical activity and cognitive benefits still need to be explored in the future.

ObjectiveTo establish the categories and structure of physical activity in children with autism spectrum disorder (ASD), and systematically evaluate the long-term effect of physical activity on the executive function of children with ASD, based on the theoretical and methodological framework of the International Classification of Functioning, Disability, and Health-Children and Youth version (ICF-CY). MethodsA search was conducted in databases such as Wanfang data, CNKI, PubMed, Web of Science and ProQuest, to collect literatures about long-term physical activity for executive function of children with ASD published from 2014 to 2023. The literatures were reviewed based on inclusion and exclusion criteria, following PRISMA guidelines for systematic review, and the quality of the included literatures were assessed with the Physiotherapy Evidence Database (PEDro) scale. ResultsTotally, ten articles were included, consisting of nine randomized controlled trials (RCTs) and one non-randomized controlled trial, with a total of 351 children diagnosed as ASD, aged three to 18 years, came from Italy, Canada, South Korea, China and the United States, published mainly after 2016. Physical activity primarily included sports activities (such as baseball, basketball, table tennis and equine-assisted activities), skill-based activities (such as cycling, cognitive-motor training and active gaming), physical fitness activities (SPARK), as well as combat-related activities (martial arts and karate); 30 to 70 minutes a time (mainly 45 minutes), one to five times a week (mainly twice a week), for two to 24 weeks (mainly twelve weeks). Long-term physical activities had been found to improve inhibitory control and cognitive flexibility in children with ASD, although the effect on working memory was inconsistent. ConclusionLong-term physical activity may positively impact on executive function in children with ASD, especially inhibitory control and cognitive flexibility. However, the effect on working memory need more researches.

Objective:To investigate short-term safety, efficacy and the learning curve of this self-developed novel transcatheter valve repair system (Neonova?) in patients with mitral regurgitation, and explore the role of perioperative echocardiography.Methods:Ten patients who visited the Union Hospital of Tongji Medical College, Huazhong University of Science and Technology from June 2021 to March 2022 and met the inclusive criteria were prospectively enrolled. All the patients were at high risk of surgery with moderate to severe or severe mitral regurgitation (MR). Clamps of Neonova? were implanted under guidance of transesophageal echocardiography and digital subtraction angiography. Clinical outcomes, echocardiography indexes and learning curves of this technique were evaluated immediately after intervention, 7 d, 1 month and 3 months post-intervention.Results:The technical success rate was 100% with MR relieved in all patients immediately after intervention. The device and procedural success rates were both 90.0% with 1 patient received surgical replacement at 37 days post-intervention while the others′ reduced to mild (8/9) and moderate (1/9) MR. New York Heart Association class and the Kansas City Cardiomyopathy Questionnaire improved significantly (all P<0.001). Mean mitral valve pressure gradient didn′t increase significantly after intervention when compared with that before intervention( P=0.324), and no mitral stenosis was observed. Left ventricular end-diastolic diameter decreased significantly ( P=0.008) during follow up.Procedure duration ranged from 60 to 300 (175.8±75.2)minutes. The simple linear regression model between procedure volume and duration showed that procedure duration decreased significantly with the increase of procedure volume ( F=15.857, P=0.004). Conclusions:Neonova? implantation can improve MR severity and clinical symptoms safely and effectively. Transthoracic echocardiography and transesophageal echocardiography are essential for perioperative management of transcatheter mitral valve repair.
