This article presents magnetic data of a 300-m-thick Mio-Pliocene red clay and Quaternary loess-paleosol sequence near Chaona town in the Central Chinese Loess Plateau. Detailed magnetostratigraphy shows that the aeolian red clay began to accumulate at ca. 8.1Ma. Here, we presented a high-resolution rock magnetic data at 20–40cm intervals within 4.5–8ka span per sample of this section, which has been published in Song et al. (2014) [1] and (2017) [2]. The dataset including the following magnetic parameters: mass magnetic susceptibility (χ), frequency-dependent susceptibility (χfd), saturation magnetization (Ms), saturation remanent magnetization (Mrs), coercive force (Bc), remanent coercivity (Bcr), saturation isothermal remanent magnetization (SIRM) and S-ratio. Magnetic susceptibility and hysteresis parameters were measured at Lanzhou University and Kyoto University, respectively. This data provides a high-resolution rock magnetic evidences for understanding East Asia Monsoon change, Asian interior aridification and tectonic effect of the uplift of the Tibetan Plateau since middle Miocene period.

Accessory Auricles: Systematic Review of Definition, Associated Conditions, and Recommendations for Clinical Practice

Abstract Accessory auricles are rare congenital abnormalities embryologically derived from the first branchial arch. Presentation may be variable with locations grouped into anatomical zones based on the frequency of location found in the literature. This study reviewed the papers between 1981 and 2017. Findings included an association with syndromes including Goldenhar, VACTERL, Treacher–Collins, Townes–Brocks, and Wolf–Hirschhorn. Based on histological and embryological evidence, the term "accessory auricle" is best used as an umbrella term to define this difference. Finally, indications are provided for imaging and laboratory investigations to guide the physician treating patients with accessory auricles. Address correspondence and reprint requests to Mark S.

A Rare Complication After Septoplasty: Visual Loss Due to Right Retinal Artery Spasm

Abstract Septoplasty is a commonly used procedure for correcting septal cartilage deformities. Hemorrhage, abscesses, scaling, adhesions, and scar tissue are often seen after the operation of the septoplasty, but temporary or permanent visual loss due to local anesthetic use has been reported very rarely in the literature. The authors also aimed to present a female patient with retinal artery spasm in the right eye after septoplasty in this article. A 27-year-old female patient was admitted to the authors' clinic with long-standing nasal obstruction and postnasal drip. There was no feature in her history and also no sign other than nasal septal deviation on physical examination. The patient was informed about the operation and the operation was planned. Emergency eye consultation was requested after the patient said that the right eye of the patient had never seen in the postoperative wake-up hall. Examination by an ophthalmologist; mild exotropia and total loss of vision in the r…

Anti-Neutrophil Cytoplasmic Antibody-Negative Central Nervous System Granulomatosis With Polyangiitis and Its Clinical Characteristics

Abstract Granulomatosis with polyangiitis (GPA) is a necrotizing granulomatous vasculitis occasionally affecting central nervous system (CNS), and GPA patients with initial CNS symptoms are even rarer, whose diagnosis is further confused by an absence of positive antineutrophil cytoplasmic antibody. The authors described the characteristics of antineutrophil cytoplasmic antibody -negative GPA with CNS onset in a patient and discussed on its management, which may contribute to future diagnosis and treatment of patients with similar conditions.
