Internet addiction(IA) as a behavioral addiction is currently becoming a serious mental health issue around the globe. According to the neurobiological model of brain development, exploring the neural mechanisms of reward seeking behavior and cognitive control in internet addicts may help in developing treatments for individuals with IA. Behavioral research has indicated that IA is commonly associated with enhanced reward sensitivity and decreased inhibitory control. Additionally, research focused on the neural mechanisms of IA indicates that deficits in the reward or cognitive control systems might be a high risk factor for addictive behaviors.Compared with substance addictions, IA, as a kind of psychological addiction, has a specific reward mechanism.While previous research has deepened the understanding of the psychological and neural mechanisms in IA, there still exist many issues surrounding diagnosis and treatment of IA: the screening criteria are not scientific; the classification is ambiguous; the effect of intervention and treatment is controversial; causal research is scarce; and research paradigms are flawed. Substantial future research is needed to explore, fully understand, and treat IA.
网络成瘾作为一种行为成瘾,目前已成为全球范围内严重的心理健康问题。根据大脑发育的神经生物学模型,探索网络成瘾者的奖励寻求行为和认知控制的神经机制可能有助于开发IA个体的治疗方法。行为学研究表明,IA通常与奖励敏感性增强和抑制控制下降有关。此外,对IA神经机制的研究表明,奖励或认知控制系统的缺陷可能是成瘾行为的高风险因素。与物质成瘾相比,IA作为一种心理成瘾,具有特定的奖励机制。虽然以往的研究加深了对IA的心理和神经机制的认识,但围绕IA的诊断和治疗仍存在许多问题:筛查标准不科学;分类是模糊的;干预和治疗的效果存在争议;因果研究很少;研究范式是有缺陷的。未来需要大量的研究来探索、充分理解和治疗IA。

Long noncoding RNA(lnc RNA) play important roles in cancer progression. HOX transcript antisense RNA(HOTAIR) was observed upregulated in a variety of tumors. Over-expression of HOTAIR is a poor prognostic factor. HOTAIR interacts with Polycomb Repressive complex 2(PRC2), resulting in histone H3tri-methylated atlysine27(H3K27me3), which silences the expression of some down-stream genes, such as WIF-1,PTEN and p21, then mediated Wnt, Akt and p53 signaling pathways transduction. As a result, the properties of tumor, including invasion and metastasis, evading growth suppressors, resisting apoptosis and inducing angiogenesis would be affected. Thoroughly elucidate mechanisms of HOTAIR in cancer development will have important theoretical significance in cancer etiology and pathogenesis. As an important biomarker and potential target, HOTAIR may also has important clinical application in cancer's early diagnosis, therapeutic evaluation,prognosis, and even potential gene therapy.
长链非编码RNA(lnc RNA)在肿瘤进展中起重要作用。HOX转录反义RNA(HOTAIR)在多种肿瘤中表达上调。HOTAIR过表达是不良预后因素。HOTAIR与Polycomb suppression complex 2(PRC2)相互作用,产生组蛋白h3三甲基化分析氨酸27(H3K27me3),沉默下游部分基因如wi -1、PTEN、p21的表达,进而介导Wnt、Akt、p53信号通路转导。从而影响肿瘤的侵袭转移、躲避生长抑制因子、抵抗细胞凋亡、诱导血管生成等特性。深入阐明HOTAIR在肿瘤发生发展中的作用机制,对研究肿瘤病因病机具有重要的理论意义。HOTAIR作为一种重要的生物标志物和潜在靶点,在癌症的早期诊断、治疗评价、预后甚至潜在的基因治疗方面也有重要的临床应用。

Aging causes a general decline in physiological function that leads to various metabolic and cardiovascular diseases. The links between aging and aging-associated diseases remain to be fully established,but recent studies demonstrate that suppressing the mammalian/mechanistic target of rapamycin(mTOR) signaling pathway extends longevity and delays aging-associated metabolic and neurodegenerative diseases. As a key regulator of metabolism and aging,the mTOR signaling pathway has now become a hot spot for the development of effective therapeutic treatment for aging and aging-related diseases.
衰老导致生理功能的普遍下降,从而导致各种代谢和心血管疾病。衰老与衰老相关疾病之间的联系仍有待完全确定,但最近的研究表明,抑制雷帕霉素(mTOR)信号通路的哺乳动物/机制靶点可以延长寿命,延缓衰老相关的代谢和神经退行性疾病。作为代谢和衰老的关键调节因子,mTOR信号通路目前已成为开发有效治疗衰老和衰老相关疾病的热点。

Inflammasomes activation is critical for both innate and adaptive immunity through their regulation of interleukin 1β(IL-1β) and IL-18.Prolonged inflammasomes activation can lead to exaggerated expression of signaling components as well as pro-inflammatory cytokines that can damage the host,resulting in chronic inflammatory diseases and autoimmune disorders.Therefore,pathways of deactivation are important to balance the immune responses.However,recent discoveries have uncovered a plethora of pathogenic strategies to inhibit the activation of inflammasome signal pathways and the production of pro-inflammatory cytokines to evade immune responses.Elucidation of these mechanisms might be helpful to the rational design of therapy against infectious diseases and other inflammasome-dependent inflammatory processes.
炎性小体的激活通过调节白细胞介素1β(IL-1β)和IL-18对先天免疫和适应性免疫至关重要。炎症小体的长期激活可导致信号成分和促炎细胞因子的过度表达,从而损害宿主,导致慢性炎症性疾病和自身免疫性疾病。因此,失活途径对于平衡免疫反应是重要的。然而,最近的发现发现了大量的致病策略来抑制炎症小体信号通路的激活和促炎细胞因子的产生,以逃避免疫反应。阐明这些机制可能有助于合理设计针对传染病和其他炎性小体依赖性炎症过程的治疗方法。

Extrasynaptic NMDA receptors, which locate in the extrasynaptic site rather than synaptic site have shown to mediate cell death pathway, while synaptic NMDA receptors play an important role in learning and memory and mediate cell survival pathway. This review discussed the reasons of their different distribution between synaptic and extrasynaptic sites, the different molecular mechanisms for signaling pathways of cell fate, as well as their roles in Alzheimer's disease(AD) based on the structure and function of NMDA receptors. Finally, we proposed a reasonable outlook on the treatment of AD from the view of extrasynaptic NMDA receptor.

MicroRNAs(miRNAs) array results have shown that the expression of miR-30b is downregulated in heart tissues from patients with familial hypertrophic cardiomyopathy who were carriers of missense mutations in the MYH7,and also in a murine heart failure model,implying that miR-30b might play an important role in heart diseases.To study miR-30b in vivo function,we generated a transgenic mouse line overexpressing miR-30b under the control of the 5.5 kb promoter of α-myosin heavy chain(α-MHC).qRT-PCR results demonstrated that miR-30b was significantly increased in the heart tissues of miR-30b transgenic mice(P 0.05).miR-30b transgenic mice did not exhibit significant heart/body weight and left ventricular(LV)/body weight changes and abnormal myocardium structure.At present,little is known about how miR-30b regulates myocardial infarction.We constructed I/R models by the coronary artery ligation method and sham-operated mice were used as controls.Biochemical detection results and TTC-Evans blue results showed that after ischemia-reperfusion,these transgenic mice had lower releases of LDH,CK and cTn玉(P 0.05)and their hearts exhibited a smaller infarct size compared to those from control mice(P 0.05).Echocardiographic results indicated that cardiac function of transgenic mice was markedly improved compared to that of control mice.In conclusion,miR-30b has protective effect upon ischemic-reperfusion injury.And it may provide a new therapeutic approach for preventing and treating myocardial infarction.
MicroRNAs(miRNAs)阵列结果显示,在MYH7错义突变携带者的家族性肥厚性心肌病患者的心脏组织以及小鼠心力衰竭模型中,miR-30b的表达下调,这意味着miR-30b可能在心脏病中发挥重要作用。为了研究miR-30b在体内的功能,我们在α-肌球蛋白重链(α-MHC) 5.5 kb启动子的控制下,构建了过表达miR-30b的转基因小鼠系。qRT-PCR结果显示,miR-30b转基因小鼠心脏组织中miR-30b水平显著升高(P < 0.05)。miR-30b转基因小鼠没有表现出明显的心脏/体重和左心室(LV)/体重变化和心肌结构异常。目前对miR-30b调控心肌梗死的机制知之甚少。采用冠状动脉结扎法构建I/R模型,以假手术小鼠为对照。生化检测结果和TTC-Evans蓝结果显示,与对照组相比,转基因小鼠缺血再灌注后LDH、CK、cTn的释放量较低(P < 0.05),心肌梗死面积较小(P < 0.05)。超声心动图结果显示,转基因小鼠的心功能较对照组有明显改善。综上所述,miR-30b对缺血再灌注损伤具有保护作用。为预防和治疗心肌梗死提供了新的治疗途径。

Secretion on the surface of human nasal mucosa contains many innate proteins,the key factors of which are SPLUNC1 and LPLUNC1,members of the palate,lung and nasal epithelium clone(PLUNC) family.These two proteins are highly expressed in nasopharyngeal epithelium with the relative specificity.Both of them have bacterial/permeability-increasing protein(BPI) domain which can bind to lipopolysaccharide(LPS) to inhibit or kill bacterial growth directly.They also have the immuno defense function to protect nasopharyngeal epithelium from Epstein-Barr virus(EBV) and some other pathogenic microorganism effectively.These proteins play a significant role in the process of chronic inflammation and carcinogenesis of nasopharyngeal epithelium by inhibiting the secretion of inflammatory factors,such as IL-6,through activating NF-κB and STAT3 signaling pathways.In addition,they also can suppress nasopharyngeal carcinoma(NPC) cell growth and induce cell apoptosis through MAPK and miR-141-PTEN-AKT signaling pathways when the PLUNC proteins are re-expressed in NPC cell lines.Further study about the mechanism of PLUNC protein family in pathogenesis of NPC has important significance for the prevention and treatment guidance of NPC.
人鼻黏膜表面的分泌物含有许多先天蛋白,其关键因子是SPLUNC1和LPLUNC1,它们是腭、肺和鼻上皮克隆(PLUNC)家族的成员。这两种蛋白在鼻咽上皮中高度表达,具有相对特异性。它们都具有细菌/通透性增加蛋白(BPI)结构域,可以与脂多糖(LPS)结合,直接抑制或杀死细菌生长。它们还具有免疫防御功能,可有效保护鼻咽上皮免受eb病毒和其他病原微生物的侵害。这些蛋白通过激活NF-κB和STAT3信号通路,抑制IL-6等炎症因子的分泌,在鼻咽上皮慢性炎症和癌变过程中发挥重要作用。此外,当PLUNC蛋白在鼻咽癌细胞系中重新表达时,它们还可以通过MAPK和miR-141-PTEN-AKT信号通路抑制鼻咽癌(NPC)细胞生长,诱导细胞凋亡。进一步研究PLUNC蛋白家族在鼻咽癌发病中的作用机制,对指导鼻咽癌的防治具有重要意义。
