Sleep Duration and Factors Related to Sleep Loss in 3-14-Year-Old Children in Beijing: A Cross-Sectional Survey.
It is known that short sleep duration adversely affects children's behavior and physical development. This study aimed to investigate the status of sleep duration in 3-14-year-old children in Beijing and explore the related factors of sleep loss with them. ⋯ Sleep loss was common among 3-14-year-old children in Beijing. Sleep duration decreased with age, especially among children over 11 years old. Factors associated with sleep loss covered sociodemographic characteristics, family sleep habits and routine activities before bedtime, and among those variables, age ≥11 years and playing with cellphones before bedtime had a greater impact on sleep duration, indicating that existing sleep loss in 3-14-year-old children could be, at least partly, improved by paying more attention to children aged of 11 years or entering Grade 5 and Grade 6 and to children with a family history of snoring; by reducing the use of electronic products before bedtime, especially cellphones; by managing weight and keeping fit; and by improving the bedtime routine.

Clinical Research of Pulmonary Langerhans Cell Histiocytosis in Children.
Pulmonary Langerhans cell histiocytosis (PLCH) is an interstitial primary pulmonary disease, characterized by Langerhans cell proliferation. It is easily misdiagnosed in children. This study aimed to characterize the clinical manifestations and features of PLCH by retrospective analysis. ⋯ PLCH mainly occurs in young children, and only a small percentage of patients have respiratory symptoms. They generally have other organ involvement. Most of PLCH children have a good prognosis and most lung lesions could have improved or stabilized. Management of "risk organ" involvement is the key point to improving EFS.

Effectiveness of Glaucoma Diagnostic Parameters from Spectral Domain-Optical Coherence Tomography of Myopic Patients.
Currently, spectral-domain optical coherence tomography (SD-OCT) appears to be a new type of glaucoma diagnostic tool. Thus, this study aimed to evaluate the effectiveness of glaucoma diagnostic parameters from SD-OCT of patients with different severities of myopia. ⋯ Glaucoma diagnostic parameters from SD-OCT were not clinically effective for the moderate- and high-myopic groups. The specificities were low. The moderate- and high-myopic groups require comprehensive analyses for the diagnoses of glaucoma. The SD-OCT database should be improved to better indicate the level of myopia based on the corresponding diopter readings.

Correlations between the Maximum Standard Uptake Value of Positron Emission Tomography/Computed Tomography and Laboratory Parameters before and after Treatment in Patients with Lymphoma.
After the first examination of patients with lymphoma diagnosis, important laboratory tests such as complete blood count; albumin, kidney and liver function tests; uric acid; β2-microglobulin; C-reactive protein (CRP); erythrocyte sedimentation rate (ESR); and lactate dehydrogenase (LDH) examinations are recommended. In this study, our aim was to find the relationship between laboratory parameters and the maximum standard uptake value (SUVmax) of positron emission tomography/computed tomography (PET/CT) in patients with lymphoma at the diagnosis and after treatment. ⋯ CRP, ESR, and LDH values may also be good predictors in patients for whom PET/CT imaging cannot be performed.

Meta AnalysisAssociation of Estrogen Receptor 1 Genetic Polymorphisms with Recurrent Spontaneous Abortion Risk.
Estrogen is one of the most important reproductive steroidal hormones and plays a critical role in the maintenance of pregnancy, and its function is mediated by estrogen receptor 1(ESR1). The polymorphisms of ESR1 were involved in recurrent spontaneous abortion (RSA); however, the association between ESR1 polymorphisms and RSA remains controversial. The present meta-analysis was aimed to clarify the association between ESR1 PvuII (-397C/T, rs2234693) and XbaI (-351A/G, rs9340799) polymorphisms and the risk of RSA. ⋯ Generally, there was no significant association between the polymorphisms of ESR1 and the risk of RSA. However, subgroup analysis indicated that ESR1 rs9340799 polymorphism was related to increased RSA risk in the non-Asian group while associated with decreased RSA risk in Asian group.
