New progress in the surgical treatment of laryngeal cyst in infants and children / 临床耳鼻咽喉头颈外科杂志

Laryngeal cyst is a cystic lesion occurring in the laryngeal cavity. Large laryngeal cyst in infants and young children can cause laryngeal wheezing and other upper airway obstruction symptoms. In severe cases, it can be even life-threatening and requires timely surgical treatment. Currently, there is a lack of unified clinical treatment strategy for this disease.This article summarizes the surgical methods, the advantages and disadvantages of various surgical methods for laryngeal cysts in recent years. It is recommended that needle aspiration, partial cyst wall resection, radical cyst dissection, transoral robotic surgery or external approach cyst resection should be selected through full communication and evaluation to clarify the extent of the lesion scope and the advantages and disadvantages of surgery.

Research progress in human symbiotic bacteria and their antibacterial molecules / 生物工程学报

With the emergence and globally spread of drug-resistant bacteria, the discovery and development of new antibacterial drugs is imminent. The symbiotic bacteria distributed in different parts of the body can produce a variety of antibacterial molecules to inhibit the colonization and infection of pathogenic bacteria. Human symbiotic bacteria provide a potential treasure house of resource for the research and development of new drugs with broad new molecular structures and action mechanism. With the further development of bioinformatics tools, synthetic biology and omics technology such as genomics, the mining of human symbiotic bacteria antibacterial molecules will be more in-depth and provide an effective way to solve the problem of drug resistance. Here, we review the antimicrobial molecules produced by human symbiotic bacteria and introduce several methods to explore the resources of natural antibacterial drugs. With the development of modern biotechnology, the antimicrobial molecules of human symbiotic bacteria will be more comprehensively and systematically explored and applied.
