RESUMO

This study aims to investigate the relationship between agricultural and animal husbandry economic development and carbon emissions and the influencing factors on carbon emissions. Here, we combine the Tapio decoupling model with the STIRPAT model by using the panel data of Henan province from 2000 to 2020 for it. Our results reveal that (i) the main relationship between agricultural and animal husbandry economic development and carbon emissions is strong decoupling and weak decoupling; (ii) the intensity of carbon emissions and labor effects can optimize their relationship; (iii) the urbanization rate and per capita consumption expenditure in rural areas have a negative impact on carbon emissions, while the carbon emission intensity and total power of agricultural machinery are opposite. Therefore, Henan province needs to optimize its industrial structure, improve the economic level of rural areas, and reduce the use of fertilizers.

RESUMO

In order to cope with global warming, China has put forward the "30 · 60" plan. We take Henan Province as an example to explore the accessibility of the plan. Tapio decoupling model is used to discuss the relationship between carbon emissions and economy in Henan Province. The influence factors of carbon emissions in Henan Province were studied by using STIRPAT extended model and ridge regression method, and the carbon emission prediction equation was obtained. On this basis, the standard development scenario, low-carbon development scenario, and high-speed development scenario are set according to the economic development model to analyze and predict the carbon emissions of Henan Province from 2020 to 2040. The results show that energy intensity effect and energy structure effect can promote the optimization of the relationship between economy and carbon emissions in Henan Province. Energy structure and carbon emission intensity have a significant negative impact on carbon emissions, while industrial structure has a significant positive impact on carbon emissions. Henan Province can achieve the "carbon peak" goal by 2030 years under the standard and low-carbon development scenario, but it cannot achieve this goal under the high-speed development scenario. Therefore, in order to achieve the goals of "carbon peaking" and "carbon neutralization" as scheduled, Henan Province must adjust its industrial structure, optimize its energy consumption structure, improve energy efficiency, and reduce energy intensity.

RESUMO

In this paper, we have applied Monte Carlo method to investigate the magnetic behaviors of the antiferromagnetic/ferromagnetic mixed spin-5/2 and spin-3/2 Ising bilayer system in a time-dependent magnetic field. We have analyzed the magnetization, magnetic susceptibility, internal energy and hysteresis loops of the system in detail. We have clarified how the different physical parameters affect the critical temperature and observed the triple-loop hysteresis behavior.

RESUMO

OBJECTIVE: To establish a systematic registry of aortic dissection in China, assess the clinical features of Chinese patients with acute aortic dissection (AAD), and compare our results with the data published by the International Registry of Acute Aortic Dissection (IRAD). METHODS: We established the first Registry of Aortic Dissection in China (Sino-RAD) in 2011. Then we evaluated 1003 patients with AAD in Sino-RAD and compared our results with those reported by IRAD. RESULTS: Compared with IRAD, the patients with AAD in Sino-RAD were significantly younger. Also, the ratio of male patients in Sino-RAD was significantly greater for the total cohort and the type A and B cohorts. The overall in-hospital mortality was 10.3% in Sino-RAD. For type A dissection, more patients in Sino-RAD received medical treatment and fewer received surgical treatment. The overall mortality, mortality of medical treatment, and mortality of surgical treatment was lower in Sino-RAD. In type B dissection, fewer patients in Sino-RAD received medical and surgical treatment and more received endovascular treatment. CONCLUSIONS: The first Sino-RAD, including 15 large cardiovascular centers throughout China, was established. Our data were compared with those reported by IRAD. We found that, compared with Western populations, Chinese patients with AAD showed 6 differences, including earlier onset, more male patients, a low incidence of hypertension, a low incidence of chest pain, a high incidence of back pain, great differences in the choice of therapeutic strategies, and relatively low in-hospital mortality.

RESUMO

OBJECTIVES: The objective of this study was to evaluate the safety and efficacy of the surgical versus transcatheter approach to correct perimembranous ventricular septal defects (pmVSDs) in a prospective, randomized, controlled clinical trial. BACKGROUND: pmVSD is a common congenital heart disease in children. Surgical closure of pmVSD is a well-established therapy but requires open-heart surgery with cardiopulmonary bypass. Although the transcatheter approach is associated with significant incidence of complete atrioventricular block, it may provide a less invasive alternative. Critical comparison of the safety and efficacy of the 2 interventions necessitates a prospective, randomized, controlled trial. METHODS: Between January 2009 and July 2010, 229 children with pmVSD were randomly assigned to surgical or transcatheter intervention. Clinical, laboratory, procedural, and follow-up data over a 2-year period were compared. RESULTS: Neither group had mortality or major complications. However, statistical analysis of the 2 groups demonstrated significant differences (p < 0.001) in minor adverse events (32 vs. 7), quantity of blood transfused, duration of the procedure, median hospital stay, median intensive care unit stay, median hospitalization cost, and median blood loss. During a median follow-up of 2 years, the left ventricular end-diastolic dimension of both groups returned to normal and there was no difference in closure rate, adverse events, and complications between groups. CONCLUSIONS: Transcatheter device closure and surgical repair are effective interventions with excellent midterm results for treating pmVSD in children. Transcatheter device closure has a lower incidence of myocardial injury, less blood transfused, faster recovery, shorter hospital stay, and lower medical expenses.
