BACKGROUND Congenital nephrogenic diabetes insipidus (CNDI) is a rare hereditary renaldisorder that is caused by mutations in AVPR2 or aquaporin 2 (AQP2). Up tonow, there are few reports about CNDI in neonates. Early clinical manifestationsof CNDI in neonates are atypical. A lack of understanding of the disease byclinicians causes frequent misdiagnoses or missed diagnoses, which may result infailure to administer treatments in time and ultimately leads to severecomplications. In this study, clinical data of a case of AVPR2 gene mutationinducedCNDI, which was confirmed by genetic testing, were retrospectivelyanalyzed to improve our understanding of this *** SUMMARY On February 1, 2020, a male neonate was hospitalized 17 d after birth due to a 7 dperiod of pyrexia. The patient’s symptoms included recurrent pyrexia,hypernatremia and hyperchloremia, which were difficult to treat. The patient wasfed on demand, and water was additionally provided between milk intakes. Acombination treatment of hydrochlorothiazide and amiloride was *** the treatment, body temperature and electrolyte levels returned to normal,the volume of urine was significantly reduced and the patient was subsequentlydischarged. Genetic tests confirmed that the patient carried the AVPR2 genemissense mutation c.541C>T (P.R181C), and the patient’s mother carried aheterozygous mutation at the same locus. After clinical treatment with acombination of hydrochlorothiazide and amiloride, the body temperature andelectrolyte levels returned to normal. Up until the most recent follow-up examination, normal body temperature, electrolyte levels and growth anddevelopment were *** CNDI in the neonatal period is rare, and its clinical manifestations are unspecificwith some patients merely showing recurrent fever and electrolyte *** testing of AVPR2 and AQP2 can be used for screening and geneticdiagnosis of CNDI.

当前,一些国家和地区以应对全球气候变化危机为由组建了绿色贸易“碳壁垒”,试图利用碳排放核算和认证优势对我国产品出口形成抑制影响。面对这些新挑战,我国需完善碳核算体系建设,助力构建公平合理、合作共赢的全球气候治理体系和全球贸易体系。本文以完善我国碳核算体系为研究目标,总结了碳核算体系的内涵及建设进展,介绍了国际绿色贸易机制的核算报告要求,并采用比较分析法分析了我国碳市场、欧盟碳边境调节机制、《欧盟电池和废电池法规》在核算边界、核算方法、数据支撑及质量保障体系3个方面的差异。研究发现,我国碳市场在核算方法上与国际绿色贸易机制具有一致性,但在碳足迹体系、数据支撑及质量保障体系方面仍存在较大差距;这导致我国出口型企业依赖现有的核算体系将不足以应对“碳壁垒”,而核算体系的差异性可能进一步影响我国新兴产业的发展。为此,我国应秉持坚决反对缺乏公平性的绿色贸易壁垒这一基本立场,同时采取完善碳核算体系的具体措施:完善产品层面的碳核算体系,建立具有高公信力的排放因子数据平台,加强科研机构的研究支撑,强化数据安全管理,尽快建设受影响企业的碳排放核算与报告能力。

Mechanical properties, microstructure and texture evolution were studied in two tensile-deformed high manganese TWIP steels at different temperatures. Special attention was paid to the effects of deformation tempera- ture and grain orientation on twinning behavior. The results showed that, at --70 ℃ and at room temperature, both twins and hexagonal martensite were found in a lower manganese steel of 26Mn. With deformation temperature ris- ing, twins became less and they disappeared at 500 ℃. Strong 〈111〉 texture appeared at 300 ℃, while it weakened at 500 ℃ due to the low strain rate and higher stacking fault energy. EBSD measurement revealed the dependence of deformation twinning on grain orientation at all test temperatures.

Based on the fractal theory, the spatial structure of China＇s vegetation has been analyzed quantitatively in this paper. Some conclusions are drawn as the following. 1） The relationships between size and frequency of patch area and patch shape index exist objectively for China＇s vegetation. 2） The relationships between perimeter and area exist objectively for China＇s vegetation. 3） The fractal dimension of evergreen needleleaf forests on mountains in subtropical and tropical zones is the largest, while the smallest for deciduous broadleafand evergreen needleleaf mixed forests in temperate zone, reflecting the most complex spatial structure for evergreen needleleaf forests on mountains in subtropical and tropical zones and the simplest for deciduous broadleaf and evergreen needleleaf mixed forests in temperate zone. 4） The fractal dimensions of China＇s vegetation types tend to decrease from thc subtropics to both sides. 5） The stability of spatial structure of deciduous broadleaf and evergreen needleleaf mixed forests in temperate zone is the largest, while the smallest for double-cropping rice, or double-cropping rice and temperate-like grain, and tropical evergreen economic tree plantations and orchards, reflecting the steadiest for deciduous broadleaf and evergreen needleleaf mixed forests in temperate zone and the most unstable for double-cropping rice, or double-cropping rice and temperate-like grain, and tropical evergreen economic tree plantations and orchards in spatial structure. 6） The stability of spatial structure of China＇s vegetation tends to decrease from the temperate zone to both sides, it is significantly pertinent to understand the formation, evolution, dynamics and complexity rule of ecosystem of vegetation.
