Background： Approximately 15-20% cases of systemic lupus erythematosus （SLE） are diagnosed in children. There have been a Few studies reporting the epidemiological data of pediatric-onset SLE （cSLE） in China, neither comparing the differences between cSLE and adult-onset SLE （aSLE）. The aim of this study was to describe the impact of age of onset on clinical features and survival in cSLE patients in China based on the Chinese SLE Treatment and Research group （CSTAR） database. Methods： We made a prospective study of 225 cSLE patients （aged 〈16 years） and 1759 patients aged 16-50 years based on CSTAR registry. We analyzed initial symptoms, clinical presentations, SLE disease activity, damages, and outcomes ofcSLE, as well as compared with aSLE patients. Results： The mean age ofcSLE patients was 12.16 ± 2.92 years, with 187 （83.1%） females. Fever （P 〈 0.001） as well as mucocutaneous （P 〈 0.001 ） and renal （P = 0.006） disorders were found to be significantly more frequent in cSLE patients as initial symptoms, while muscle and joint lesions were significantly less common compared to aSLE subjects （P 〈 0.001 ）. The eSLE patients were found to present more fi＇equently with malar rash （P = 0.001; odds ratio {OR], 0.624; 95% confidence interval [CI ], 0.470 0.829） but less tYequently with arthritis （P 〈 0.001 ; OR, 2.013; 95% CI, 1.512-2.679） and serositis （P = 0.030; OR, 1.629; 95% CI, 1.053 2.520）. There was no significant difl＇erence in SLE disease activity index scores between cSLE and aSLE groups （P = 0.478）. Cox regression indicated that childhood onset was the risk factor for organ damage in lupus patients （hazard ratio 0.335 [0.170 0.658], P = 0.001）. The survival curves between the cSLE and aSLE groups had no significant difference as determined by the log-rank test （0.557, P = 0.455）. Conclusions： cSLE in China has different clinical features and more inflammation than aSLE patients. Damage may be less in children and there is no difl＇erence in 5- year survival bet

Spatial transcriptomics technique detects RNA sequences (St?hl et al.,2016) and quantifies their expression in the positional context (Ke et al.,2013),which can provide important information such as cell heterogeneity,cell developmental trajectory,differential gene expression between tissue regions or *** date,it is becoming a powerful tool for exploring tumorigenesis (Ren et al.,2023),cerebral neurodevelopment (Shi et al.,2023),embryonic development(Arutyunyan et al.,2023),and other biological ***-dimensional(3D) spatial transcriptome typically requires stacking multiple tissue slices to obtain a 3D atlas (Schott et al.,2024);therefore it prefers a method that meets high throughput,large sample sizes,and affordable cost to cover large regions of the ***,the lack of a single method that meets all of these requirements limits large-scale application of 3D spatial transcriptomics.

Solution-processed Cu（In,Ga）Se2（CIGS） solar cells suffer from serious carrier recombination and power conversion efficiency（PCE） loss because of the poor film properties and easy formation of ***, we propose Ag&Se co-selenization strategy to enhance the crystallization and passivate harmful defects of the CIGS films. The formation of Ag-Se phase during the selenization process enables the formation of large grains and suppresses the deep level defects. It is found that Ag doping can enlarge the depletion region width, lower the Urbach energy and prolong the carrier lifetime. As a result, a champion solution-processed CIGS solar cell presents a high efficiency of 16.48% with the highly improved opencircuit voltage（VOC） of 662 m V and fill factor（FF） of 75.8%. This work provides an efficient strategy to prepare high quality solution-processed CIGS films for high-performance CIGS solar cells.

近年来,创新网络作为区域和城市创新驱动力的重要性得到了广泛关注。一些研究将网络关系视为知识在城市内和城市间传播的渠道,并通过网络分析视角洞察城市创新的结构和动态。然而,城市创新的网络机制,特别是数字经济发展背景下的数字赋能城市创新能力提升机制还有待进一步研究。本文利用长三角城市群26个城市2009年—2018年联合申请专利数据构建了城市创新网络,探讨了网络结构属性——小世界和结构洞对城市创新能力的影响。结果表明,小世界与城市创新能力呈“倒U型”关系,数字经济发展水平正向调节了二者之间的“倒U型”关系,结构洞对城市创新能力具有正向影响。本文厘清了创新网络结构对城市创新能力的影响,回应了以往研究关于小世界和结构洞对创新影响的理论争议,为区域创新的理论研究提供了新颖性观点,深化了对城市群创新发展规律的认识,对推进中国城市群协同创新具有重要意义。
