摘要： 《甲骨文字研究》是著名古文字学家、“甲骨四堂”之一的“鼎堂”郭沫若先生早年研究甲骨文字的第一部专著。《释龢言》是《甲骨文字研究》中唯--篇涉及音乐乐器之名的考释之文。在该篇考释中,郭氏以“和”“龢”为古今字而起论,先援《尔雅·释乐》中的“小笙谓之和”为据,认定“和”字的本义就是“笙”。

摘要： Clinician-determined performance status is widely used to determine pediatric clinical trial eligibility; however, the study by Maurer et al suggests that clinicians' (and parents') assessments are discordant with children's own reports. This editorial outlines the conundrum of if and how to proceed with performance assessments in pediatric clinical research.

摘要： 人芽囊原虫是一种常见肠道寄生原虫,感染者一般无明显临床症状,少数感染者尤其是合并感染或免疫系统功能受损者可出现腹痛、腹泻、恶心、呕吐等症状,严重时可能危及生命。本文就人芽囊原虫合并感染其他病原体及其他疾病研究进展作一综述,为人芽囊原虫感染防控提供参考。

关键词： 背德者   自我   爱   宗教   社会  

摘要： 主要从爱、宗教和社会公共领域三个方面,探讨纪德笔下作为背德者的自我及其特征。爱所体现的是自我的情感世界,宗教表现了自我的终极关切,二者都属于广义的内在精神世界;比较而言,社会公共领域体现了自我与外在社会政治现实的关系。无论是从中世纪走向现代,还是现代社会自身的演进,自我意识的萌发、演化,都无法离开以上三个方面。在纪德的笔下,自我既以背德者为人格形态,又体现于多样的社会领域(包括不同的文明形态),通过以上方面的考察,纪德的作品展现了个体丰富的内心世界和行为方式,由此也展现了自我形象的多样形态。

摘要： IntroductionThe Job Demand–Control–Support (JDCS) model suggests that a combination of job demands (JD), job control (JC), and job support (JS) forms eight different job types. In the last three decades, these constellations of job types have been explored by adopting the traditional variable-centered perspective. In this sense, these constellations of job types as postulated in the JDCS model have been rarely confirmed empirically and few studies were able to find all the hypothesized *** aim of this study was to expand previous research on the JDCS model by adopting a person-centered approach to identify relevant job type *** applied latent profile analysis (LPA) to identify profiles in a sample of Italian workers (n=348). LPA including one to eight latent profiles were estimated by using MPlus 7 robust maximum likelihood estimator, considering the following goodness-of-fit indices: Bayesian information criterion, Akaike information criterion, Constant AIC; bootstrapped likelihood ratio p-value and the Lo-Mendell Rubin adjusted likelihood *** showed a five-latent-profiles solution: isolated high strain (high JD, low JC, low support; n=36, 10.35%), cowboy-hero (high JC, low support; n=16, 4.60%), moderate-strain (moderate JD, moderate JC, low support; n=125, 35.92%), collective-low-strain (low JD, high JC, high support; n=37, 10.63%), and supported (high support, n=134, 38.51%).ConclusionResults from our study partially agree with JDCS theorization as it replicated three of the eight-profile solutions identified, finding two new constellations. In fact, we were not able to identify the passive jobs, active jobs, obedient comrade, and participatory leader constellations. This study extends previous research on JDCS, highlighting that future studies should consider empirically identified profiles rather than theoretically defined subgroups. Finally, one of the main theoretical contribution of the present study was

摘要： GoalAcute corona virus disease (COVID-19) appears mild in children in comparison to adults. But multisystem inflammatory syndrome in children caused concerns among pediatricians since its first description in May *** this paper we describe a Tunisian experience in management of *** reviewed medical files of all children diagnosed with MIS-C and admitted in the pediatric C department of Bechir Hamza Children’s Hospital of Tunis. We analysed demographic, medical and biological *** enrolled 11 patients. The first one was admitted in September 2020, weeks after the beginning of the second wave of Covid 19 in *** age was 5 years, nine of them were boys. One patient had neonatal sclerosing cholangitis. The most common symptoms were: fever (11/11), gastrointestinal symptoms (8/11), rash, conjunctivitis and cheilitis (5/11).Five patients had exposure with a confirmed family member. Physical examination at admission found high fever (n=10) and tachypnea (n=8) with a median respiratory rate at 30. Median heart rate was 110 and median oxygen saturation was 99%. Four patients had abdominal tenderness. During hospital stay, one patient presented generalized seizure due to multisystem *** testing found medium white blood cell count 10820/mm3, neutrophil cell count 8463/mm3, lymphocyte 1507/mm3 (6 patients had lymphopenia <1500), median C-reactive-protein level was 177 mg/l [83-322mg/l] and median erythrocyte sedimentation rate was 65 mm [42-130 mm]. Five patients had elevated troponin level. Median D-dimer level was 1,8 mg/l and median fibrinogen level was 4,5 g/l. One patient had positive SARS-Cov-2 RT-PCR and the others had positive serology. Four patients presented heart dysfunction and received vasopressive support. Coronary dilatation was found in four patients. Three patients were admitted in ICU, all of them had cardiogenic shock.

关键词： 文化贸易   竞争力指数   RCEP   国际竞争力  

摘要： 近年来,我国文化贸易发展较快,贸易规模不断扩大,贸易产品结构不断完善,贸易空间分布集中度下降,但文化产品与文化服务贸易发展不平衡、文化服务贸易内部结构严重不平衡。利用联合国商品贸易数据库中文化产品贸易和部分文化服务贸易的数据,计算IMS指数、TC指数、RCA指数和IIT指数,从产品和国家两个层面分析我国文化贸易的国际竞争力,发现:与RCEP其它成员国相比,我国文化产品贸易尤其是劳动密集型产品贸易国际竞争力较强,但文化服务贸易竞争力较弱;RCEP主要成员国无论在文化产品还是文化服务方面都展露出巨大的发展潜力,国际竞争力不断加强。今后,我国可以利用RCEP协定合作的机会,通过重点发展与RCEP国家的文化贸易与投资,快速提升我国文化贸易的国际竞争力:一是要大力发展“互联网+文化”,提高文化产业附加值;二是要加强与RCEP国家的交流与合作,打造区域文化产业链;三是利用RCEP规则,助力文化产业“走出去”,进一步扩大开放。

摘要： A 55-year-old man with a history of bilateral laser-Assisted in situ keratomileusis (LASIK) and subsequent enhancement over 15 years ago presented to our facility to investigate refractive surgery options. The patient reported progressive blurring and fluctuation of vision and desired independence from contact lenses and spectacles. Uncorrected distance visual acuity (UDVA) was 20/30-2.0 in the right eye and 20/400 in the left eye, corrected to 20/60 in the left eye. Manifest refraction was +0.75-1.75 × 180 diopters (D) in the right eye and-3.50-3.50 × 64 D in the left eye. Keratometry readings were 43.9/41.1 @ 25 in the right eye and 49.3/46.8 @ 2 in the left eye. On slitlamp examination, the patient showed diffuse subepithelial fibrosis and confluent circumferential elevation, respecting the LASIK flap margin and extending centrally into the visual axis (Figure 1Figure *** photograph of the left eye showing subepithelial fibrosis in a circumferential configuration, extending centrally into the visual axis.). Fluorescein pooling was also observed. Anterior segment ocular coherence tomography (OCT) demonstrated subepithelial hyperreflective density in the left eye (Figure 2Figure ***-OCT of the left eye demonstrating prominent, thick, subepithelial hyperreflective density appreciable in the horizontal (top) and vertical (bottom) axes.). Pentacam showed irregularity and inferior steepening up to 52.0 D (Figure 3Figure *** tomography of the left eye demonstrating inferior steeping up to 52.0 D, 25 m anterior elevation, and pachymetry of 620 m.).A review of the patient's records from 4 years ago revealed UDVA of 20/30-2 in the right eye and 20/20 in the left eye with manifest refraction of +1.00-1.50 × 30 D in the right eye and-0.25 D in the left eye. Keratometry then showed 39.52/40.91 @ 98 in the right eye and 39.85/40.42 @ 75 in the left eye. Patient's slitlamp examination revealed minimal subepithelial irregularity without endothelial changes in both
