Esophageal squamous cell carcinoma (ESCC) is one of the most common types of gastrointestinal cancers, and the fourth leading cause of cancer-related deaths in China. Early detection and intervention in time may dramatically increase the survival of the patients by initiating treatment regimens during earlier stages of ESCC or even during precancerous stages. Molecular classification will be useful for subtyping esophageal tumors or precancerous lesions to improve current therapeutics or early intervention of the disease. In this review, we summarize the findings in investigating the molecular alterations and clinical relevance of ESCC.

Fibroblast growth factor 21: a novel metabolic regulator from pharmacology to physiology

Fibroblast growth factor 21 (FGF21) is a member of the fibroblast growth factor family. It actually functions as endocrine hormones but does not regulate cell growth and differentiation. It is demonstrated that FGF21 acts on multiple tissue to coordinate carbohydrate and lipid metabolism, including enhancing insulin sensitivity, decreasing triglyceride concentrations, causing weight loss, ameliorating obesity-associated hyperglycemia and hyperlipidemia. Moreover, FGF21 also plays important roles in some physiological processes, such as fasting and feeding, growth hormone axis and thermogenic function of brown adipose tissue. Clinical relevance of FGF21 in humans is still unclear, and the basis and consequences of increased FGF21 in metabolic disease remain to be determined. Both the pharmacological actions and physiological roles make FGF21 attractive drug candidates for treating metabolic disease, but some questions remain to be answered. This article concentrates on recent advances in our understanding of FGF21.

Female infertility represents a major challenge for improving the production efficiency in the dairy industry. Historically, fertility has declined whereas milk yield has increased tremendously due to intensive genetic selection. evidence reveals about 60% pregnancy loss takes place during the first month following fertilization. Meanwhile, early embryo development is significant for somatic cell nuclear transfer in cattle as a large proportion of cloned embryos fail to develop beyond peri-implantation stage. Oocyte quality is of utmost importance for the early embryo to develop to term for both fertilized and cloned embryos. Epigenetic reprogramming is a key process occurring after fertilization and critical roles of epigenetic modifiers during preimplantation development are now clear. Incomplete epigenetic reprogramming is believed to be a major limitation to cloning efficiency. Treatment of cloned embryos with epigenetic modifying drugs (e.g., Trichostatin A) could greatly improve cloning efficiency in both mice and cattle. Recently, the rapid progress in high-throughput sequencing technologies has enabled detailed deciphering of the molecular mechanisms underlying these events. The robust efficiency of genomic editing tools also presents an alternative approach to the functional annotation of genes critical to early development.

急性心肌梗死(AMI) 是世界上致死和致残的主要病因。及时再灌注法是AMI的标准疗法,能够缩小梗死面积,提高患者存活率和改善预后。然而,25 %的患者在患心肌梗死(Ml) 后会进一步发展成为心力衰竭(HF),且其中50%的患者会在5年内死亡。由于梗死面积是预断病人病情( 包括HF的形成) 的主要指标,因此,改善心肌的治疗方法具有极大的应用前景。 在过去30年中,研究者已发现多种能够刺激内源性心肌保护通道的刺激物,这些刺激物能在缺血预适应(IPC)和缺血后适应以及心肌缺血情况下启动保护机制。当在心肌缺血发生前、发生期间或发生后即刻使用刺激物,在远离心脏的血管床中发生的短暂、可逆性局部缺血就会即刻引发心肌保护机制——这种现象被分别称为远程缺血预适应,远程缺血期适应和远程缺血后适应。尽管目前的研究尚未完全阐明远程缺血预适应(RIPC) 的作用机制,但RIPC与IPC在机制上有很多共同之处。RIPC的发现使研究转向了远程非缺血刺激的应用,包括神经刺激( 脊髓刺激和迷走神经刺激) 以及电针(EA)。笔者与其他研究人员发现并阐述了非缺血现象的机制,并将其定义为远程创伤预适 应(RPCT)。通过刺激皮肤感觉神经来启动RPCT,这与穴位处神经刺激和EA既有相似性又有一定差异性。笔者在此次研究中还发现,可通过采用腹中线电刺激(与EA疗法相似) 来模拟RPCT,而且作为预适应刺激和后适应刺激( 在应用再灌注法时),这种激活心肌保护机制的模式是非常有效的。通过对这些心肌保护现象的研究,学术界对心肌保护机制形成了一种全面且综 合的理解,而且在过去的5~10 年期间, 这种理解变得逐渐清晰,即无论是缺血性刺激诱导还是非缺血性刺激诱导,其机制均相似。通过对文献中多种数据的综合考虑,我们认为所有的这些心肌保护“适应”现象均表示心肌保护机制的启动是从心肌适 应网(含有特定介质和心肌细胞生存感受器) 的不同切入点进行的,该切入点包括NF-κB、Stat3/5、蛋白激酶C、舒缓激肽和mitoKATP 通道。神经系统传导通路可能代表了一种激活心脏和其他器官适应的新机制。研究表明,由于IPC和RIPC存在一定风险并且无法应用于某些患者,所以它们很难被转化为临床应用。因此,近期又新兴了一种神经刺激和痛感刺激的应用,这是一种激活心肌适应的潜在的非缺血性无创方法。作为引起心脏保护作用众多方法之一的后适应重点强调了临床相关性,这种临床相关性有助于在现有成熟的药物与电子疗法中加速新的治疗方向的突破。

This study proposes the ontological reconstruction of the current clinical terminology of traditional Chinese medicine (TCM). It also provides an overview of preliminary work related to the said reconstruction, including the ontology-based analysis of TCM clinical terminology. We conclude that the ontological reconstruction of TCM clinical terminology provides a proper translation from the idealized organizational model to real-world implementation and to a formalized, shared, and knowledge-based framework.

In light of the rapid increase in the number of obesity incidences worldwide, obesity has become an independent risk factor for chronic kidney disease. Obesity-related glomerulopathy (ORG) is characterized by glomerulomegaly in the presence or absence of focal and segmental glomerulosclerosis lesions. IgM and complement 3 (C3) nonspecifically deposit in lesions without immune-complex-type deposits during ORG immunofluorescence. ORG-associated glomerulomegaly and focal and segmental glomerulosclerosis can superimpose on other renal pathologies. The mechanisms under ORG are complex, especially hemodynamic changes, inflammation, oxidative stress, apoptosis, and reduced functioning nephrons. These mechanisms synergize with obesity to induce end-stage renal disease. A slow increase of subnephrotic proteinuria (<3.5 g/d) is the most common clinical manifestation of ORG. Several treatment methods for ORG have been developed. Of these methods, renin–angiotensin–aldosterone system blockade and weight loss are proven effective. Targeting mitochondria may offer a novel strategy for ORG therapy. Nevertheless, more research is needed to further understand ORG.
