Central precocious puberty (CPP) is a rare disease of poorly understood etiology. The cause is mostly idiopathic. However, congenital and acquired structural changes in the central nervous system are also involved. ⋯ Proper diagnosis and treatment make it possible to avoid a number of complications of untreated CPP. There are only a few studies analyzing the prevalence and risk factors for the disease. The aim of this paper is to discuss the current causes of CPP with particular consideration of neurological aspects.

Xianlinggubao (XLGB) capsule is a traditional Chinese medicine, which is approved by the Chinese State Food and Drug Administration (CFDA) for osteoarthritis (OA) and osteoporosis (OP). However, as a capsule with complex ingredients, the molecular mechanisms supporting the therapeutic effects have not been explored. ⋯ Neuroactive ligand-receptor interaction, cAMP signaling pathway, and calcium signaling pathway might be the critical pathways upon which the capsule might act. The present study laid down a foundation to understand the molecular mechanisms of the XLGB capsule and also provided fundamental information for better improvement of the drug with the concept "less herbal materials for achieving equal treatment efficacy".

Atherosclerosis has become a worldwide medical burden. Our previous studies have shown that artemisinin (ART) had the capability to reduce atherosclerosis. Emerging evidence indicates that long non-coding RNAs (lncRNAs) are involved in the development of atherosclerosis. However, whether lncRNAs might participate in the mechanism through which artemisinin mitigates atherosclerosis has not been reported. ⋯ These findings indicated the possible mechanism and therapeutic role of lncRNAs in artemisinin treatment of atherosclerosis and provided a theoretical basis for the future application of artemisinin in patients with atherosclerosis.

Aortic stenosis (AS) is considered severe when the aortic valve area (AVA) is < 1.0 cm2 and the mean aortic valve gradient (mAVG) exceeds 40 mm Hg. Since many patients with AVA < 1.0 cm2 do not manifest an mAVG > 40 mm Hg, we sought to determine the AVA at which mAVG tends to exceed 40 mm Hg in a sample of subjects with varied transvalvular flow rates. ⋯ Subjects with AVA of 0.8 and 0.9 cm2 rarely had mAVG > 40 mm Hg, even when the transvalvular flow rate was normal. Using current guidelines, it is not clear if such cases should be classified as severe.

Long non-coding RNAs (lncRNAs) functioning as competing endogenous RNAs (ceRNAs) play critical roles in tumour progression. However, prognosis-related ceRNA networks in lung adenocarcinoma (LUAD) have not been well characterised. ⋯ This ceRNA network contributes to understanding the pathogenesis of LUAD. Furthermore, the molecules in the network are valuable predictive factors for LUAD prognosis as well as potential therapeutic biomarkers.
