With the increasing incidence of male reproductive system diseases and reproductive dysfunctions, diagnosis and treatment of male infertility and fertility preservation have become clinical challenges to be overcome. Organoids, a kind of cell product cultured in vitro under different microenvironments by using adult stem cells or embryonic stem cell, can possess histological anatomy and physiological function that are similar to natural tissues. In recent years, technological breakthroughs have been made in testicular organoids in terms of sperm proliferation and differentiation induced in vitro, providing a new idea for solving the above problems. This article briefly introduces common testicular organoid techniques (micropore culture, microfluidics culture method, three-layer gradient system, air-liquid interface culture, extracellular matrix hydrogel scaffold, hanging drop cultures, and 3D printing technology, etc.), including technical features, research conditions, technical bottlenecks and summarizes the application characteristics and situations of some ordinary organoid culture solutions in the field of testicular organoids as well.

Burning mouth syndrome (BMS) is a chronic oral and facial pain disorder characterized by burning pain in the oral mucosa, with multiple pathogenic factors including psychosocial, neuropathological, endocrine, and immune factors. There is still a lack of effective treatment options that have been demonstrated to work. With the development of research on the pathogenesis and treatment of BMS, multidisciplinary comprehensive treatment has gradually been introduced and become a new trend of diagnosis and treatment. Before multidisciplinary treatment, it is necessary to go through a full and comprehensive diagnosis and analysis, select the best comprehensive treatment plan, take the diagnosis and treatment of stomatology as the basis and premise, and apply other multidisciplinary combined treatment, including the treatment of concurrent diseases, psychological interventions, correction of bad habits, etc. A combination of laser therapy and psychological intervention is a more effective treatment method among the current treatment methods, with high comfort and good acceptance by patients. If necessary, mecobalamin tablets, clonazepam α-lipoic acid and other drugs can be used to nourish nerves and provide symptomatic treatment. The comprehensive multidisciplinary treatment of BMS is expected to become a new trend and provide a new strategy for improving the therapeutic effect.
