Design and development process of molecular diagnostic reagents is critical to quality management system of in vitro diagnostic reagent. Based on the technical characteristics of molecular diagnostic reagents, the study analyzed the concerned key control points and common problems in the process of design and development from the view of registration quality management system. It aimed at offering technical guidance on design and development process of molecular reagents and registration quality management system to enterprises, thus improving the product development efficiency, optimizing the quality management system, and increasing the efficiency and quality of registration and declaration.

Nucleic acid detection technique has good sensitivity and specificity and is widely used in in vitro diagnosis, animal and plant commodity quarantine, forensic identification, and other fields. However, it is susceptible to carryover contamination during the operation and leads to false-positive results, which seriously affects the detection accuracy. Therefore, finding an effective solution to prevent and eliminate nucleic acid carryover contamination has become particularly urgent. This study compared several different methods for removing nucleic acid contamination and confirmed that sodium hypochlorite solution and PCRguard reagent could effectively eliminate nucleic acid carryover in the liquid and on surfaces of different materials. Besides, the combination of sodium hypochlorite solution and PCRguard can solve the nucleic acid aerosol contamination. This study proposes solutions for the routine prevention of carryover contamination and removal of aerosol that has occurred in molecular diagnostic laboratories.

Histopathological classification is in a pivotal position in both basic research and clinical diagnosis and treatment of gastric cancer. Currently, there are different classification systems in basic science and clinical application. In medical literatures, different classifications are used including Lauren and WHO systems, which have confused many researchers. Lauren classification has been proposed for half a century, but is still used worldwide. It shows many advantages of simple, easy handling with prognostic significance. The WHO classification scheme is better than Lauren classification in that it is continuously being revised according to the progress of gastric cancer, and is always used in the clinical and pathological diagnosis of common scenarios. Along with the progression of genomics, transcriptomics, proteomics, metabolomics researches, molecular classification of gastric cancer becomes the current hot topics. The traditional therapeutic approach based on phenotypic characteristics of gastric cancer will most likely be replaced with a gene variation mode. The gene-targeted therapy against the same molecular variation seems more reasonable than traditional chemical treatment based on the same morphological change.
