The former genus , which has been merged as a clade within the genus (Liliaceae), represents one of the most complicated and unclear groups included in the latter. Research on members of the Nomocharis clade has been quite limited due to the sampling difficulties caused by its selective environmental preferences. In this study, we propose a new species within this clade, , as a further bridge connecting the former genus with other members of the genus We conducted morphological clustering, phylogenetic, and comparative genomics analyses of nuclear internal spacers and the newly generated complete chloroplast genome, in conjunction with previously published sequences, and performed ancestral state reconstruction to clarify the evolutionary pattern of important traits in .

Events associated with bone metastases can seriously affect patient quality of life, through pain, hypercalcemia, bone marrow regeneration disorders, and spinal cord compression. In this nonrandomized controlled clinical trial study, we focused on the relationship between bone metastasis, pain, and cytokines before and after radiotherapy.

Chinese acupuncture has shown definite anti-ageing effect as arthralgia relief, movement improvement, energy increase and immunity enhancement; however, the mechanisms underlying are far away from illumination. Increasing literature has highlighted the role of alterations in mitochondrial function as a potential central regulator in ageing biology; mitophagy plays a critical role in mitochondrial quality control.

Results: Two full length transcriptome gene sets of flowering and non-flowering saffron crocus were established separately using the single-molecule real-time (SMRT) sequencing method.
Early adverse life stress is an important dangerous factor in the development of psychiatric disorders, particularly depression. Available clinical antidepressant agents, such as fluoxetine, [a selective serotonin reuptake inhibitor (SSRI)], are unsatisfactory because of their side effects. SiNiSan (SNS) is a classic Chinese medicine prescription regarded to disperse stagnated liver qi to relieve qi stagnation.

Methods: A case-control investigation was performed to compare 37 infants affected by NSCL/Ps with 60 babies without cleft malformations. Their genomic DNA samples were obtained, and the LINE-1 and IRF6 methylation levels were measured by using Sequenom MassArray.
Background: The genetic factors causing cleft lip with or without cleft palate (CL ± P) are still unclear. The SNPs in FOXE1 gene were associated with CL ± P. However, the results have been inconsistent.

In order to establish a set of methods to evaluate the quality of saffron, High Performance Liquid Chromatography/Mass Spectrometry (HPLC/MS) were used to identify the apocarotenoids extracted from saffron stigmas. TOPSIS method was applied to evaluate the qualities of saffron.

Objective: To describe the epidemiological characteristics of selected congenital limb malformations (CLM) in newborns of Hengyang.
Methods: During the period of 2008-2010, cluster sampling survey was adopted to investigate the congenital limb malformations of neonates born to women resident in Hengyang, including Nanyue District, Zhuhui District, Changning City and Hengshan County. Each newborn was examined for the screening of CLM after birth.
Aminopeptidase N (APN/CD13), as a zinc-containing ectoenzyme, plays a critical role in the process of tumor angiogenesis, invasion and metastasis. Through the docking-based virtual screening of chemical databases and the further activity assay, we discovered that compound 10c exhibits potent and selective inhibitory ability towards APN. In addition, a series of indoline-2,3-dione derivates have been designed and synthesized as APN inhibitors.

Based on our previous work that L-isoserine dipeptide derivatives were potent APN inhibitors, we designed and synthesized L-isoserine tripeptide derivatives as APN inhibitors. Among these compounds, one compound 16l (IC₅₀ = 2.

Previous studies indicate that pranlukast reduces ischemic tissue injury partially through decreasing vascular permeability, but its effect on ischemic injury in endothelial cells is not known. Thus, in this study, we investigated the effect of pranlukast on ischemia-like injury induced by oxygen-glucose deprivation (OGD) in EA.
