ABSTRACT

Long non-coding RNAs (lncRNAs) reportedly function as important modulators of gene regulation and malignant processes in the development of human cancers. The lncRNA JPX is a novel molecular switch for X chromosome inactivation and differentially expressed JPX has exhibited certain clinical correlations in several cancers. Notably, JPX participates in cancer growth, metastasis, and chemoresistance, by acting as a competing endogenous RNA for microRNA, interacting with proteins, and regulating some specific signaling pathways. Moreover, JPX may serve as a potential biomarker and therapeutic target for the diagnosis, prognosis, and treatment of cancer. The present article summarizes our current understanding of the structure, expression, and function of JPX in malignant cancer processes and discusses its molecular mechanisms and potential applications in cancer biology and medicine.

ABSTRACT

Building a strong public health system has become an urgent task in the new era. Based on more than eight years of systematic research, we believe that five aspects need to be prioritized for a strong system. First, we should change the perspective on public health, using the word “gonggong jiankang” to replace “gonggong weisheng” and the word “gonggong jiankang tixi” to replace “gonggong weisheng tixi”, to lead the public health system development. Second, we should develop a suitable public health system and continuously improve the health capacity for governance. Third, we should make it clear that the goal of building a strong system is not far-fetched, and we need to consolidate the existing institutional advantages of China’s public health system: when encountering major problems, we can maintain a unified goal and mobilize the whole society to cooperate effectively to accomplish the goal. However, we need to make up for shortcomings one by one, especially to solve the key problem of lacking a strong coordination mechanism in daily work. Fourth, we should pursue excellence and consolidate the“suitable” mechanism proven in the process of coping with the COVID-19, so that efficient mechanisms to deal with major issues can be used in routine work, and efforts should be made to consolidate the advantages of prevention and control of infectious diseases and emergency response,so as to achieve the balanced development of regions categories and units.Finally, it is necessary to strengthen the coordination of government and research institutions, in the aspects of technological innovation, talent team building and accurate consulting services, and work together to pursue a suitable and strong system to realize the modernization of the health system and capacity for governance.

ABSTRACT

Long noncoding RNAs (lncRNAs) are involved in vital life processes of gene expression, epigenetic regulation and X-chromosome inactivation. lncRNAs are also closely associated with tumor initiation and progression. Moreover, lncRNAs may enter human circulation system in the form of microvesicle or exosome, or in combination with RNA binding protein. Interestingly, the circulating lncRNAs are widely existed in body fluids, such as blood and urine. We review the origin of circulating lncRNAs, and the detection methods as potential biomarkers. We focus on the early diagnosis value of circulating lncRNAs as tumor biomarkers in lung, breast, gastric, liver, colorectal and prostate cancers. Compared with the traditional biomarkers, the circulating lncRNAs show the unique advantages and clinical values as novel biomarkers.

ABSTRACT

Objective To study the variation of the level of NOS,NO and Ang (1-7) in spontaneously hypertensive rat(SHR).Methods SHR were divided randomly into 3 groups:Bushenyixin group(n=8),valsartan group (n=8),and model group (n=7).Each group was given Bushenyixin tablet,valsartan,and saline by gavage respectively.After 4 weeks,the concentration of NOS,NO,Ang (1-7) in plasma and the concentration of NOS,NO in aorta were be observed.Results The concentration of NO in plasma was significantly lower in the Bushen-Yxin group than for model group(15.500±4.375)μmol/L vs.(26.000±2.828)gmol/L,P<0.05.The concentration of NO in aorta and Ang1-7 in plasma were significantly higher in the Bushen-Yixin group than in the model group [(35.604±7.505)μmol/L vs.(17.437± 11.649) μ mol/L,(45.542 ± 12.726)ng/L vs.(25.521 ± 2.727) ng/L,P<0.05].The concentration of NO in aorta was significantly higher in Bushen-Yixin group than in the valsartan group [(21.537± 13.484) μmol/L,P<0.05].Conclusion Bushen-Yixin tablet had effects of increasing of NO level in aorta and Ang (1-7) level in plasma in spontaneously hypertensive rat.

ABSTRACT

RNA interference (RNAi) is a process to inhibit specific gene expression via the degradation of the target mRNA induced by the double strand RNA. The use of RNAi in mammals as a tool to study gene function has rapidly developed in recent years. Here we described the novel progress and applications of the vector for mediating RNAi in mammals.
