ObjectiveTo summarize the relationship of microRNA (miRNA) to metastasis and invasion of breast cancer. MethodDomestic and international publications involving the relationship of miRNA to breast cancer were screened and reviewed. ResultsmiRNA played a key role in the process of breast cancer metastasis. According to its function, it could be distinguished from cancer-promoting gene (such as miR-21, miR-10b, etc.) to suppressor gene (such as miR-31, let-7, etc.). ConclusionThe more detailed experimental studies about the relationship of miRNA to metastasis and invasion of breast cancer need to be researched in order to provide a new method for the diagnosis and treatment of breast cancer metastasis and invasion.
The success of staged Fontan palliation for patients with single ventricle is related to low pulmonary vascular resistance (PVR). The complications of high PVR in Fontan physiology are numerous, such as low exercise tolerance, low cardiac output, ventricular function failure and protein-losing enteropathy; eventually it leads to failing Fontan. Therefore, a low PVR is crucial in Fontan patients. Now, targeted therapies decreasing PVR has been an advanced research hotspot in Fontan patients. In this review we present an overview of the safety and efficacy of the therapy with bosentan or sildenafil on elevated pulmonary artery pressure and pulmonary vascular resistance in Fontan patients.
Human immunodeficiency virus (HIV) infection mainly attacks the human immune system, causing a variety of opportunistic infections and tumors, among which neoplastic diseases are serious and life-threatening. In recent years, with the popularization of highly effective anti-retroviral virus, the disease spectrum of HIV infected people has changed greatly, the incidence of non-acquired immune deficiency syndrome (AIDS) related tumors has increased significantly, and the diagnosis rate of esophageal cancer patients with HIV/AIDS has also increased. However, there is no consensus on how to standardize the diagnosis and treatment of esophageal cancer patients with HIV/AIDS. This article reviews the epidemiological characteristics, diagnosis and treatment of esophageal cancer patients with HIV/AIDS.
Abstract Precision medicine is an ideal medical paradigm which combines modern scientific methods with traditional medical methods to diagnose, treat and evaluate the physical function and nature of diseases more precisely, and to maximize health benefits and minimize the risk of individuals and society with the most effective, safest, and the most economical medical service. Evidence-based medicine is necessary to verify the precision of diagnosis and treatment. In this review, we clarified the conception of precision medicine and the relation between precision medicine and evidence-based medicine. Moreover, we reviewed the application of precision medicine in the field of cerebrovascular disease. We pointed out that such new technologies as genetics, bioinformatics, molecular imaging and management provided tools to realize the idea of precision medicine, and high-quality evidence-based studies provided a guarantee for the clinical practice of precision medicine. In summary, precision medicine is an individualized medical mode that based on the context of a patient's genetic information, living environment and clinical data, etc. to provide precise treatment strategies for the prevention and treatment of disease, but still the promotion of precision medicine should be based on clinical validation under the guidance of evidence-based medicine. Thus, long-term exploration and unremitting efforts are required to achieve the idea of precision medicine.
