Progress in detection methods for urogenital Chlamydia trachomatis infection / 中华微生物学和免疫学杂志

Urogenital Chlamydia trachomatis ( Ct) infection is a serious sexually transmitted disease worldwide. The early diagnosis and treatment of Ct infection is critical for disease control. This review summarized the progress in the development of methods for detecting Ct infection and discussed the advantages and disadvantages of various methods. The emerging omics techniques in recent years are expected to be new tools for the detection of Ct infection. It is necessary to develop the omics techniques into rapid and accurate point-of-care tests that can be carried out in various testing environments for more effective patient management and disease control.

Omics techniques and biobanks to find new biomarkers for the early detection of acute lymphoblastic leukemia in middle-income countries: a perspective from Mexico / Técnicas ómicas y biobancos para el hallazgo de nuevos biomarcadores para la detección temprana de leucemia linfoblástica aguda en países de ingresos medios: una perspectiva mexicana

Abstract: Acute lymphoblastic leukemia (ALL) affects the quality of life of many children in the world and particularly in Mexico, where a high incidence has been reported. With a proper financial investment and with well-organized institutions caring for those patients, together with solid platforms to perform high-throughput analyses, we propose the creation of a Mexican repository system of serum and cells from bone marrow and blood samples derived from tissues of pediatric patients with ALL diagnosis. This resource, in combination with omics technologies, particularly proteomics and metabolomics, would allow longitudinal studies, offering an opportunity to design and apply personalized ALL treatments. Importantly, it would accelerate the development of translational science and will lead us to further discoveries, including the identification of new biomarkers for the early detection of leukemia.

Resumen: La leucemia linfoblástica aguda (LLA) afecta la calidad de vida de una gran cantidad de individuos en edad pediátrica en todo el mundo; particularmente en México, donde se ha reportado una alta incidencia. Con un apropiado fondo de inversión financiera, así como instituciones adecuadamente organizadas al cuidado de los pacientes con LLA, en conjunto con plataformas sólidas para llevar a cabo análisis globales y de alto rendimiento, se propone la creación de un repositorio para la conservación de suero y células provenientes de médula ósea y sangre derivadas de pacientes pediátricos con LLA al diagnóstico. Estos recursos, en combinación con las tecnologías ómicas, en particular la proteómica y la metabolómica, podrían permitir el establecimiento de estudios longitudinales y ofrecer una oportunidad para el diseño y aplicación de tratamientos personalizados para la LLA. Esta estrategia permitiría acelerar el desarrollo de la ciencia traslacional, favoreciendo el hallazgo de importantes descubrimientos, incluyendo la identificación de nuevos biomarcadores para la detección temprana de la leucemia.

Ethical issues in the study of clinical laboratory data based on omics techniques / 中华医学科研管理杂志

With dramatic decline of genome sequencing cost,high-throughput sequencing technologies have been applied in clinical laboratory field,and play an increasingly important role in clinical diagnosis and treatment in complex diseases.Based on omics techniques,clinical laboratory data recording patient's diagnosis information has become the important independent medical research resources of the major health industry.Because these data include the patient's identity information,there are a series of ethical issues to be solved,such as protection of patients' informed consent right,patient privacy protection,information security protection,when carrying out the medical health big data research.Based on these problems,it proposed clinical laboratory data should be standard extraction,establishment of clinical laboratory data base for teaching,training,in order to improve the utilization of medical resources.Moreover,it is best to implement the written informed consent during the process of sample collection,informing the patient the data collected in diagnosis and treatment process may be used in related research in future.

Discussion on Techniques of Preliminary Safety Evaluation of Transgenic Chinese Herb / 世界科学技术-中医药现代化

Insertion of foreign genes into the genome map of Chinese herb always produces the intended beneficial effects, but also the unintended effects. Analysis of genomic function and metabolic end products based on the principle of substantial can reveal the influence on the quality of herbs, which is able to provide valuable refer-ence for the following evaluation on pharmacology and toxicology.
