PurposeResearch on the relationship between sleep duration and obesity defined using multiple anthropometric and bioelectrical indices in women remains scarce. We aimed to explore the association between sleep duration and body mass index (BMI), waist-hip ratio (WHR), body fat percentage (PBF) and visceral fat area (VFA) among females.MethodsWe recruited women for medical examination using multistage cluster sampling. Sleep was assessed using Pittsburgh Sleep Quality Index (PSQI) and sleep duration was categorized into short (ResultsA total of 7,763 women with a mean age of 42.6 ± 13.5 years were included. The percentage of women reporting short and long sleep was 10.3 and 13.4% respectively. The mean BMI, WHR, PBF and VFA were 23.07 ± 3.30 kg/m2, 0.78 ± 0.06, 32.23 ± 6.08% and 91.64 ± 35.97cm2, respectively. Short sleep was independently associated with 35% (95% CI: 1.05–1.75) increased odds of general obesity (BMI ≥ 28 kg/cm2), and long sleep was associated with 18% (95% CI: 1.01–1.37) increased odds of visceral obesity (VFA > 100 cm2). No association was observed between sleep deprivation or excessive sleep and high WHR or high PBF.ConclusionIn women, short sleep was associated with an increased odds of general obesity, whereas long sleep was associated with an increased odds of visceral obesity. Longitudinal observations are needed to confirm this cross-sectional relationship.

We report a 49-year-old woman who presented with a 4-month-history of headache, nausea, and no epilepsy. Magnetic resonance imaging (MRI) showed a mass in the left temporal lobe region. The edges were unclear, and it was a non-cystic and obvious perifocal edema. The radiologist first considered that it was a high-grade glioma. Macroscopy found that the tumor measured 6.2 cm × 5.2 cm × 5 cm. Microscopy found that the tumor cells were pleomorphic and indicated the presence of many epithelioid/rhabdomyoid cells, multifocal necrosis, and significant bleeding. The distribution of the reticular fibers was segmented, which is difficult to diagnose when it is accompanied by partial anaplastic features. The immunohistochemical makers of the tumor cells were positive for GFAP, Oligo-2, S-100, ATRX, INI1, BRAF (V600E), and P53 but negative for IDH1 (R132H). The tumor cells exhibited a low proliferating index of Ki-67 (< 5%). Molecular pathological detection revealed that the BRAF (V600E) gene was positive, and there was no mutation in the IDH and TERT genes, no 1p/19q-codeleted, and no methylation in the MGMT promoter. The final pathological diagnosis was pleomorphic xanthoastrocytoma (PXA, WHO grade II) with partial anaplastic features. The patient had no additional adjuvant radiation and underwent temozolomide-based chemotherapy. No recurrence was found over a 30-month follow-up. Therefore, the pathological diagnosis combined with the clinicopathological features, histopathological morphology, and related molecular detection is of great significance for the accurate classification, prognostic evaluation, and precise treatment decision for glioma.

Focusing on the future development, the latest research progress of U.S. military about pint-sized fire control system of UAV is introduced. By analyzing the UAV fire control system elements under the two operating procedures, we explored and definated the key technologys and its application characteristics about information fusion,artificial intelligence,data chain and intelligent sensor etc.offered the research priorities of autonomous system, and at last we made out the road for development about the two kinds of system.
