Our aim is to examine the impact of DICER1 mutations on the pathogenesis of pleuropulmonary blastoma(PPB) by evaluating the mutation frequency and investigating the family history of Chinese patients with PPB. The family histories of 12 children with PPB recruited consecutively were surveyed. Blood samples from patients and their first-degree relatives were tested for DICER1 mutations. Whole-genome sequencing of blood samples and formalin-fixed and paraffin-embedded(FFPE) tumor tissue was performed in one family with twins. Twelve patients with PPB included six type II and six type III cases. Seven of the12 patients harbored DICER1 mutations, six of which were frameshift or nonsense mutations. Another case carried a germline DICER1 mutation affecting the splice site. FFPE sample had a nonsense mutation in TDG and missense mutations in *** addition, two cases with DICER1 mutations were found to have lung cysts preceding the diagnosis of PPB. Furthermore, one patient had a family history remarkable for thyroid diseases. Our results indicate that the germline mutation frequency in Chinese patients with PPB is similar to the ones reported for patients from USA, UK, and Japan. Moreover, our study strongly suggests that investigating the family history and detecting germline DICER1 mutations might be of benefit to increasing awareness and improving the accuracy of the differential diagnosis of PPB from non-malignant lung cysts.

当前,集体经营性建设用地市场化流转的逐利性使其在用途上倾向于能带来更多经济效益的工商业用途,却对农地生态安全造成严重的不利后果,体现在:以向外排放为附产品的集体经营性建设用地市场化流转引起农地环境污染、以资源索取为目标的集体经营性建设用地市场化流转造成了农地生态破坏,以资源消耗为特征的集体经营性建设用地市场化流转造成农地生物多样性的衰竭。因此,集体经营性建设用地市场化流转背景下建立农地生态补偿具有现实必要性,应当对农地生态补偿的主体与客体、标准、期限、方式等基本要件进行合理设计,这对于促进生态补偿的实施至关重要。在管理机制方面,应构建生态补偿的协调联动机制、公众参与机制、绩效评价机制、生态追责机制等;在保障机制方面,应注重法律保障、政策保障、经费保障、宣传保障等。

我国环境治理数字化要求治理理念的开放创新、治理决策的科学及时、治理方式的智慧赋能以及治理结构的互动制衡。从功能上看,数字化技术在我国环境治理领域的运用,推动了我国环境治理由政府主导向多元协同治理、由末端治理向全过程治理、由人工治理向数智化治理的环境现代化治理模式转型。然而,我国环境治理数字化却面临着公民隐私权被侵犯、数据安全防范形势严峻、算法依赖导致的技术统治、责任主体难以确定以及环境实质性参与缺失等风险。基于此,在法治推进路径上,应强化环境治理数字化中个人隐私权的规范性保护,完善环境治理数字化中的数据安全防范体系,加强对环境治理数字化中技术统治的多维规制,明确界定环境治理数字化中的责任主体,促进环境治理数字化中公众的实质性参与。

农民自发型、村集体推动型以及政府主导型等不同的土地流转模式在促进农民增收方面的作用机理各不相同,但都有不同程度的增收效果。在实践中,各地实施土地互换、采用土地股份合作、设立农村土地银行等不同的土地流转方式助推农民增收,成效显著。然而,农村土地流转在助推农民增收的同时,也面临着农村土地流转相关法律和制度不完善、现行农村土地流转模式助推农民增收的效应有待提高、农民参与农村土地流转存在障碍、农村土地流转助推农民增收的服务与监督体系存在缺失等一系列现实问题。应从完善农村土地流转相关法律制度、完善现行土地流转模式、促进农地流转中的农户参与、完善农地流转的服务与监督机制等方面探索其实现路径。

Clinical research on the accuracy of diagnostic tests,the power of prognostic markers,and the efficacy and safety of interventions are the cornerstone of evidence-based health care.1 Transparency and sufficient reporting are important for conveying research findings to the public,practitioners,and students in medicine because insufficient reporting of results would hinder assessment for a study’s strengths and weaknesses and thus hamper integration of evidence,even from well-conducted research.2 However,the reporting quality of articles in most healthcare journals remains inadequate.

从生态影响的角度分析,农村集体经营性建设用地市场化流转过程中存在的问题正以"农地非农化"、"农地非粮化""、农地工业化"等不利于农地生态安全的形式表现出来。在集体经营性建设用地市场化流转中确立农地生态安全的理念,不仅是实现农地发展权的基本要求,也是维护和保障农民生态权益的必然要求,还是实现生态公平的根本要求。因此,现阶段为遏制集体经营性建设用地市场化流转对农地生态环境的破坏,必须在集体经营性建设用地市场化流转中确立农地生态安全的理念,在制度实现上体现为三个方面:一是构建农地生态安全理念下的集体经营性建设用地市场化流转法律制度模式框架;二是以保障农地生态安全作为集体经营性建设用地市场化流转的基本原则;三是在集体经营性建设用地市场化流转的具体制度中纳入关于农地生态安全的技术规范,即建立集体经营性建设用地市场化流转的生态安全标准制度、集体经营性建设用地市场化流转的生态安全许可制度、集体经营性建设用地市场化流转的生态安全评价制度等。
