Achieving a narrow emission bandwidth is long pursued for display applications. Among all primary colors, obtaining pure red emission with high visual perception is the most challenging. In this work, CsPbI halide perovskite nanoplatelets (NPLs) with rigorously controlled 2D [PbI] octahedron layer number (n) are demonstrated.

Methods: We included 663 patients who underwent surgery for degenerative spinal disease and received general anesthesia. The LASSO method was used to screen essential features associated with POD.
To explore the effects of stand density and climatic factors on radial growth of , we used tree ring chronology to examine the radial growth changes in a secondary forest under different levels of stand density (thinning). The meteorological data combined with the driving factors of growth were analyzed. The results showed that the radial growth of was significantly affected by stand density.

As a result, color shift of RGB micro-LED displays may become visually noticeable. To address this issue, we first analyze the angular distributions of RGB micro-LEDs and obtain good agreement between simulation and experiment.

Methods: From Baoji city, 358 cases of forensic autopsy specimens from a series of routine exams were collected. And histopathological diagnoses were reviewed.
Objective: To investigate the clinical significance of changes in T wave and ST segment amplitudes on electrocardiogram (ECG) from supine to standing position in children with unexplained chest tightness or pain in resting stage.
Methods: A total of 122 6-14-year-old children with a chief complaint of unexplained chest tightness or pain (resting stage) underwent head-up tilt test (HUTT). According to HUTT results, these children were divided into HUTT-positive (n=61) and HUTT-negative groups (n=61).
Objective: To investigate the clinical significance of 24-hour blood pressure monitoring (ABPM) for evaluating the treatment outcome of nerve-mediated syncope (NMS) in children.
Methods: Twenty-eight children with NMS confirmed by a head-up tilt table test (HUTT) (12 males and 16 females, aged 6-13 years) and with a chief complaint of unexplained syncope or pre-syncope between February 2010 and August 2012, were included in the study. These children received health education combined with therapy using oral rehydration salts solution and were then reexamined for clinical symptoms as well as HUTT and ABPM results.

Background: To investigate dynamic fluctuations of serum viral load and peripheral T-lymphocyte subpopulations of chronic hepatitis B patients and their correlation during entecavir therapy.
Methods: Fifty-five patients received entecavir 0.5 mg/d therapy.
