The hydraulic fracturing technology has been widely utilized to extract tight resources.Hydraulic frac-turing involves rock failures,complex fracture generation,proppant transport and fracture closure.All these behaviors affect the productivity of fractured wells.In this work,the advances and challenges in hydraulic fracturing development of tight reservoirs are summarized from following aspects:the hy-draulic fracture propagation,the proppant transport and distribution in hydraulic fractures,the calcu-lation of hydraulic fracture conductivity,and productivity and/or pressure analysis model of multi-stages fractured horizontal wells.Current fracture propagation simulation methods generate only limited propagation paths and cannot truly reflect the complexity of the propagation.The current proppant migration and distribution research is mainly focused on indoor experimental studies of proppant migration in a single fracture or branched fracture,and simulation studies on proppant migration and distribution in a small-scale single slab fracture.Whereas fractures formed after hydraulic fracturing in tight reservoirs are generally complicated.There is a lack of models for calculating complex fracture conductivity that take into consideration the effect of proppant placement and proppant distribution in fractures,fracture surface roughness and dissolution,diffusion,deposition,elastic embedding,and creep caused by stress.The productivity models of fractured horizontal wells are mostly conducted based on the original reservoir fluid saturation and pressure distribution.Most of the studies are focused only on one aspect of the fracturing process.Predications of well performance after fracturing based on these studies are often inconsistent with actual field data.The paper also discusses the future research di-rections of fracturing in tight reservoirs and the results may be used to promote the development of tight reservoirs.

作为深具哲学气质的理论人类学家,列维-斯特劳斯构建了具有“元人类学”意义的结构人类学,意在处理人类的无意识层面上的心智运作机制。故在探讨亲属关系这一传统人类学的主要议题时,列维-斯特劳斯关注的不是“亲属关系”本身,而是“亲属关系的基本结构”。通过将结构语言学的音位学原理应用于亲属关系分析,列维-斯特劳斯区别了意识层面上的亲属关系“称谓系统”与亲属关系“态度系统”,构拟了基于三种维度亲属关系的无意识层面上的亲属关系结构(亲属关系的原子),从而将“婚亲”与“血亲”关系的分析推进到规范性的理论层次,由此指出人类的“婚姻关系”不仅以“乱伦禁忌”这样一种否定性原则规范,更有正面的、肯定性的限制规则,此即“交表亲”婚制。借对“交表亲”婚制的研究,列维-斯特劳斯将莫斯关于社会组织得以成立的“互惠原则”扩展为更抽象与普遍的“交换”逻辑。

We demonstrate that charge carrier diffusion lengths of two classes of perovskites, CH3NH3PbI3−x Cl x and CH3NH3PbI3, are both highly sensitive to film processing conditions and optimal processing procedures are critical to preserving the long carrier diffusion lengths of the perovskite films. This understanding, together with the improved cathode interface using bilayer-structured electron transporting interlayers of [6,6]-phenyl-C61-butyric acid methyl ester (PCBM)/ZnO, leads to the successful fabrication of highly efficient, stable and reproducible planar heterojunction CH3NH3PbI3−x Cl x solar cells with impressive power-conversion efficiencies (PCEs) up to 15.9%. A 1-square-centimeter device yielding a PCE of 12.3% has been realized, demonstrating that this simple planar structure is promising for large-area devices.

Transparent electrodes(TEs)with high chemical stability and excellent flexibility are critical for flexible optoelectronic devices,such as photodetectors,solar cells,and light-emitting diodes.Ultrathin metal electrode(thickness less than 20 nm)has been a promising TE candidate,but the fabrication can only be realized by vacuum-based technologies to date,and require tedious surface engineering of the substrates,which are neither ideal for polymeric based flexible applications nor suitable for roll-to-roll large-scale manufacture.This paper presents high-performance nanostructured transparent metal electrodes formation via displacement-diffusion-etch(DDE)process,which enables the solution-processed sub-20-nm-thick ultrathin gold electrodes(UTAuEs)on a wide variety of hard and soft substrates.UTAuEs fabricated on flexible polyethylene terephthalate(PET)substrates show a high chemical/environmental stability and superior bendability to commercial flexible indiumtin-oxide(ITO)electrodes.Moreover,flexible organic solar cells made with UTAuEs show similar power conversion efficiency but much enhanced flexibility,in comparison to that of ITO-based devices.

A Robust N-Terminal Pro-Brain Natriuretic Peptide Assay for Clinical Diagnosis of Heart Failure in Elderly Patients

引用

Journal of Analysis and Testing 2024年第1期8卷 74-82页

作者： Xue Gong Jiangling wu Jiajia Zhang zhongwei Jiang Yi Wang Pu Zhang Engineering Research Center for Biotechnology of Active Substances(Ministry of Education) Chongqing Key Laboratory of Green Synthesis and ApplicationsCollege of ChemistryChongqing Normal UniversityChongqing 401331China Chongqing Research Center for Pharmaceutical Engineering College of PharmacyChongqing Medical UniversityChongqing 400016China Department of Clinical Laboratory University Town Hospital of Chongqing Medical UniversityChongqing 401331China

Heart failure(HF)is a clinical hallmark of cardiovascular syndrome leading to substantial morbidity,repeated hospitalization,and enormous healthcare expenditure.As elderly populations continue to increase,biomarker-guided diagnosis and treatment for age-related cardiac decline have become essential.Accumulating evidence demonstrates that N-terminal proBNP(NT-proBNP)can provide a unique window into the diagnosis and risk stratification with HF.Herein,a simple yet robust aptasensor is developed for on-site recognizing the NT-proBNP by its targeting aptamer,thus achieving the accurate diagnosis of HF.This aptasensing system is prepared by absorbing the fluorophore-labeled aptamer strand onto the graphene oxide(GO),leading to efficient quenching without possible off-site signal leakage.The aptamer strand can specifically identify target NT-proBNP molecules via a versatile conformational transformation,resulting in the desorption of the aptamer-NTproBNP complexes from GO and re-generation fluorescence signal,thus allowing sensitive detection of NT-proBNP in 37 clinical blood samples.Taking advantage of the high specificity of aptamer-guaranteed recognitions of NT-proBNP,this aptasensor system readily achieves better diagnostic performance for HF than commercially adopted chemiluminescence immunoassay(Siemens,CLIA)in hospitals in terms of accuracy(89.2%vs 83.8%),specificity(89.5%vs 84.2%),and positive predictive value(88.9%vs 83.3%).This work provides a stable option for the diagnosis and treatment of elderly HF-related diseases inclinics.

目的对比高孕激素状态下促排卵(PPOS)方案及拮抗剂方案在卵巢储备功能减退(DOR)患者中的促排卵效果、实验室培养及首次冻融胚胎移植(FET)妊娠结局,为改善DOR患者的辅助生殖助孕结局提供科学参考。方法回顾性分析2016年1月—2022年6月本院生殖医学中心收治的302周期DOR患者的临床资料,根据促排卵方案分为PPOS组(216周期)和拮抗剂组(86周期),根据年龄将PPOS组分为:(1)低龄组:78周期,年龄≤35岁;(2)高龄组:138周期,年龄>35岁。同理,将拮抗剂组分为:(1)低龄组:36周期,年龄≤35岁;(2)高龄组:50周期,年龄>35岁。比较各组患者的临床资料、促排卵效果、实验室培养及首次FET妊娠结局。结果两组患者的年龄、不孕年限、身体质量指数(BMI)、不孕类型、受精方式、基础FSH及LH水平等资料比较均无差异(P>0.05)。以35岁作为划分生育年龄节点,不同促排卵方案的低龄组及高龄组患者的基础FSH及LH水平具有差异性(P0.05);低龄及高龄DOR患者的获卵数相比,PPOS组均低于拮抗剂组,差异具有统计学意义(P0.05),拮抗剂组卵子利用率更高,其MⅡ数高于PPOS组,差异具有统计学意义(P0.05)。结论 PPOS方案促排卵方法简单、费用低,已较大规模的成功助孕DOR患者,但在高龄DOR患者中易发生卵子早排。拮抗剂方案卵子利用度高,优质胚胎率、可用胚胎率及临床妊娠结局与PPOS方案相当,且可以新鲜移植,缩短了患者周期内妊娠时间,近年来更多地应用于DOR患者,但启动周期总费用较高。在临床工作中,应根据DOR患者具体情况,严格掌握不同促排卵方案的适应证与禁忌症,制定安全、有效、个体化的促排卵方案,以获得良好的妊娠结局。
