Regional Inequalities and Influencing Factors of Residents' Health in China: Analysis from the Perspective of Opening-Up.

While opening-up promotes regional economic development, its impact on the residents' health level cannot be ignored. Based on provincial data of China from 2009 to 2020, the Gini Coefficient and Theil Index are used to analyze the regional inequalities in residents' health in China. The Difference-in-Difference model is constructed to study the impact of China's opening-up policies and other factors on residents' health. The results show that, firstly, the health levels of Chinese residents have steadily improved and regional inequalities have been gradually narrowing. Secondly, the Belt and Road Initiative has significantly improved the residents' health along the route, while the Pilot Free Trade Zone, which is another important opening-up policy in China, has had an inhibitory effect on the health of residents. Thirdly, it is proven that the Belt and Road Initiative improves the health of residents in provinces along the route by increasing the degree of opening-up and improving the regional environmental quality. This study will support and advance the UN's Sustainable Development Goals (SDGs), especially SDG3 (Good Health and Well-being) and SDG10 (Reduced Inequalities).

Agriculture-Induced N2O Emissions and Reduction Strategies in China.

Greenhouse gases are one of the most important factors in climate change, their emissions reduction is a global problem. Clarifying the spatial patterns of N2O, as an important component of greenhouse gases, it is of great significance. Based on the planting and breeding data of China from 2000 to 2019, this paper measures the N2O emissions of agricultural systems, and uses kernel density to explore the spatial distribution differences between the eight major economic zones. Finally, the proposed emissions reduction countermeasures are provided. The research results show that the N2O emissions of China's agricultural system showed a trend of increasing first and then decreasing, and in 2019, the national N2O emissions were 710,300 tons, agricultural land emissions and animal husbandry emissions were the main sources of N2O emissions. The difference in N2O emissions by province was significant, the concentration trend was more prominent, and the differences of N2O emissions between provinces and regions were diverse. In order to achieve the reduction in N2O emissions, it is necessary to carry out low-carbon production of staple grains for different parts and economic zones, and focusing on low-carbon production in the Central Part and the West Part, as well as the Northeast and the Greater Southwest zones, is essential.

Application of loop-mediated isothermal amplification and next-generation sequencing in the diagnosis of maternal tuberculosis with multiple negative tests: A case report.

RATIONALE: Tuberculosis (TB) is one of the top 10 causes of death worldwide and is the leading infectious cause of death. The incidence of TB, especially active TB, is increased in pregnant and postpartum women. Newborns can be infected with TB from their mothers through several routes. Diagnosis of TB in pregnant women and infants is difficult. Here, we report the simultaneous postdelivery diagnosis of TB in a mother and infant pair. PATIENT CONCERNS: A 28-year-old woman presented with a sudden onset of convulsions, loss of consciousness, coughing, fever, and breathing difficulty. Her 18-day-old infant daughter developed cough and wheezing. DIAGNOSIS: The mother's chest computed tomography showed diffuse interstitial changes and both lungs' exudation. Enhanced cranial magnetic resonance imaging showed scattered nodular intracranial lesions. A tuberculin skin test and an interferon-gamma release assay were negative. Xpert MTB/RIF (Xpert) testing and acid-fast bacilli smear of bronchoalveolar lavage (BAL) fluid of the mother were negative. Loop-mediated isothermal amplification of BAL fluid was positive for Mycobacterium tuberculosis, and next-generation sequencing confirmed the diagnosis of TB. A biopsy specimen also showed characteristic TB findings. The mother was diagnosed with TB and TB encephalitis. The infant's BAL fluid was positive for acid-fast bacilli and Xpert and, therefore, was diagnosed with TB. INTERVENTIONS: The mother was treated with rifampicin and isoniazid for 9 months, ethambutol and pyrazinamide for 3 months, and prednisolone acetate for 8 weeks. The infant received ventilator-assisted ventilation for 10 days and anti-tuberculous therapy for 11 months. OUTCOMES: After anti-tuberculous therapy, the mother and infant both gradually recovered. The mother's chest computed tomography showed significant recovery 9 months after discharge. The infant developed normally during the 11-month follow-up. LESSONS: This mother-child case pair highlights the value of loop-mediated isothermal amplification and next-generation sequencing as new diagnostic technologies for diagnosing TB in patients with multiple negative tests.

Facile Synthesis of Mo2C Nanoparticles from Waste Polyvinyl Chloride.

The resource utilization of waste plastic can not only control environmental pollution but can also ease up the problems of lack of energy resources. In this study, molybdenum carbide (Mo2C) nanoparticles have been synthesized by utilizing waste polyvinyl chloride as a carbon source in a stainless-steel autoclave at 600 °C. X-ray diffraction pattern indicates that the product is orthorhombic phase Mo2C. Electron microscopy photographs show that the obtained Mo2C product consisted of crystalline nanoparticles with an average size of 50 nm. The possible formation mechanisms of Mo2C have been also briefly discussed on the basis of the structures of the products synthesized with different reaction times. The effects of reaction temperature on the crystallinity and microstructure of the obtained products have been investigated. The results show that higher reaction temperature promotes the formation of Mo2C with high crystallinity.

[Hypereosinophilic syndrome initially presenting pulmonary embolism: a case report and review of the literature].

OBJECTIVE: To analyze clinical features of hypereosinophilic syndrome with multiple thrombosis and improve the understanding of eosinophilia resulting in thrombotic diseases. METHODS: " Eosinophils increased, thrombocytopenia, deep vein thrombosis", as the Chinese keywords, "hypereosinophilic, thrombocytopenia, deep vein thrombosis", as the English keywords and to retrieve the literature from Wanfang database and Pubmed database January 2002- January 2012, a total of 17 articles, 5 Chinese articles, 4 in English, exclude those 2 articles which do not clearly diagnosis, a total of 7 articles were included, reports 8 cases, including 5 male, 3 female, age ranged from 24 to 75, combine the characteristics of the cases which reported in these literatures and our case, to make a literature review. RESULTS: A male, 27 years old complains shortness of breath, chest pain and blood in the sputum, pulmonary embolism diagnosed by chest enhanced CT, while deep vein thrombosis was diagnosed, laboratory examinations showed that blood eosinophils and thrombocytopenia. According to the literature that eosinophils can damage the vascular endothelial cells, leading to multiple arterial and venous thrombosis, anticoagulation while glucocorticoid treatment is effective. CONCLUSIONS: As one of eosinophilia, hypereosinophilic syndrome can involve multiple organs and cause multiple thrombosis. Anticoagulation and corticosteroids can reduce eosinophil count and decrease its toxins which can injure vascular endothelial.
