Hereditary vitreoretinal amyloidosis with transthyretin Gly83Arg variant, a long-term study.

Background: This study evaluated the clinical data on ophthalmic follow-up and treatment efficacy of hereditary vitreoretinal amyloidosis kindred due to transthyretin Gly83Arg variant over a 15-year follow-up period.

Methods: The clinical data of patients with hereditary ATTRG83R amyloidosis from 2006 to 2021 were analysed retrospectively. Sanger sequencing of the transthyretin gene, detailed medical history, pedigree charting, and systemic and ophthalmic examinations were carried out in all patients.

Prognostic role of pretreatment skeletal muscle index in gastric cancer patients: A meta-analysis.

The association between pretreatment skeletal muscle index (SMI) and long-term survival of gastric cancer patients remains unclear up to now. The aim of this meta-analysis was to identify the prognostic value of pretreatment SMI in gastric cancer. The PubMed, EMBASE and Web of Science electronic databases were searched up to 5 June 2022 for relevant studies.

Diagnosis and treatment of tuberculosis presenting as uveitis based on stochastic simulation in systems biology.

Tuberculous uveitis can be a manifestation of extrapulmonary tuberculosis or an allergic reaction to tuberculosis infection. The clinical signs and symptoms of other uveitis causes are generic, making a false diagnosis simple. We present a brief introduction to theoretical modelling and simulation in systems biology and explore the consequences of TB uveitis if left untreated.

Province- and Individual-Level Influential Factors of Depression: Multilevel Cross-Provinces Comparison in China.

Rapid social change has given rise to a general increase in psychological pressure, which has led to more and more Chinese people suffering from depression over the past 30 years. Depression was influenced not only by individual factors but also by social factors, such as economy, culture, politics, etc. These social factors were measured at the national, provincial, or community levels.

Multitask bidirectional digital coding metasurface for independent controls of multiband and full-space electromagnetic waves.

Full-space metasurfaces demonstrate powerful abilities in manipulating electromagnetic (EM) waves, but most of them are usually single band. Here, a multiband bidirectional digital coding metasurface is proposed for multiple tasks, which can achieve completely different functions in up to six frequency bands when the EM waves are incident from the front and back of the metasurface. As a proof-of-concept, we design and fabricate a dual-band full-space metasurface with integrated functions of reflection, transmission, holographic imaging, and vortex-beam forming, and a six-band full-space metasurface with completely independent holographic imaging functions at different frequency bands.

Dual-band chiral metasurface for independent controls of spin-selective reflections.

The development of chiral metasurfaces with spin-selective reflection or transmission provides a new way to control the circularly polarized (CP) waves. However, it is still a great challenge to independently manipulate the polarization, frequency, and phase of the spin-selective reflected waves in different operating bands, which may have potential applications in improving the data capacity of microwave and optical communication systems. Here, a dual-band chiral metasurface is proposed to generate gigantic intrinsic chirality with strong circular dichroism (CD) in two different frequency bands by piecing two typical mono-chiral units together.

Achieving physical examination competence through optimizing hands-on practice cycles: a prospective cohort comparative study of medical students.

Background: Deliberate practice (DP) was proposed for effective clinical skill training, which highlights focused, repetitive practice and feedback as the key points for practice. Although previous studies have investigated the effect of feedback in DP, little is known about the proper repetitive cycles of clinical skills training especially in physical examination (PE) training.

Methods: We drew learning curves and designed a comparative study to find out the optimal number of hands-on practice cycles, an important aspect of DP, in abdominal PE training for medical students.

Broadband Spin-Selective Wavefront Manipulations Based on Pancharatnam-Berry Coding Metasurfaces.

Spin-selective reflection metadevices are usually realized by using chiral metamirrors that can reflect one state of circularly polarized (CP) waves and restrain the other one. However, most of the chiral metamirrors only exhibit chirality in a narrow band, which may impede their potential applications. Here, we propose a Pancharatnam-Berry (PB) coding metasurface composed of the spin-decoupled elements to realize broadband spin-selective reflections with arbitrary wavefront manipulations.

Adult primary testicular lymphoma: clinical features and survival in a series of patients treated at a high-volume institution in China.

Background: To retrospectively investigate the clinical characteristics, initial treatment, relapse, therapy outcome, and prognosis of Chinese patients with primary testicular lymphoma (PTL) through analysis of the cases of our institute.

Methods: From December 2008 to July 2018, all patients with PTL were included in this study. Kaplan-Meier method was used to estimate PFS and OS.

Perceptions and Attitudes toward Brain Donation among the Chinese People.

Postmortem human brain donation is crucial to both anatomy education and research. The China Human Brain Banking Consortium was established recently to foster brain donation in China. The purpose of this study was to gain information about the public perception of and attitudes toward brain donation and to identify factors that may impact the willingness to participate in brain donation among the Chinese people.
