OBJECTIVE: To study surgical techniques and clinical applications of the intranasal endoscopic combined approach in maxillary sinus benign lesions surgery. METHOD: A retrospective clinical analysis of 27 patients "whose unilateral maxillary sinus benign lesions operated by the intranasal endoscopic middle meatus with inferior meatus tears recess approach surgical treatment was studied. RESULT: Benign lesions were confirmed by pathology in all patients before and after surgery as to rule out malignancy. All patients had been followed up for 12 to 24 months. Twenty-seven cases resulted in normal luminal epithelium and inferior turbinate shape after surgery. Only one case of papilloma relapsed 2 months after operation. So far, the papilloma has not recurred after the second surgery. There were no epiphora in all cases. CONCLUSION Endonasal endoscopic expand anterior tears recess approach have great and clear view. This approach made us accurately, mini-invade and completely remove the maxillary sinus benign lesions. It is a physiological and functional surgery and has great advantage in the nasal cavity disease treatment.

An increasing number of studies have recently indicated the important effects of gut microbes on various functions of the central nervous system.However, the underlying mechanisms by which gut microbiota regulate brain functions and behavioral phenotypes remain largely unknown. We therefore used isobaric tags for relative and absolute quantitation (iTRAQ)-based quantitative proteomic analysis to obtain proteomic profiles of the hippocampus in germ-free (GF), colonized GF, and specific pathogen-free (SPF) mice. We then integrated the resulting proteomic data with previously reported mRNA microarray data, to further explore the effects of gut microbes on host brain functions. We identified that 61 proteins were upregulated and 242 proteins were downregulated in GF mice compared with SPF mice. Of these, 124 proteins were significantly restored following gut microbiota colonization. Bioinformatic analysis of these significant proteins indicated that the glucocorticoid receptor signaling pathway and inflammation-related pathways were the most enriched disrupted pathways. This study provides new insights into the pathological mechanisms of gut microbiota-regulated diseases.
