Objective To investigate the roles of hypoxic stimulation in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP) by comparing the variation and differences of inflammatory factors secreted from epithelial cells of nasal polyps and normal nasal mucosa under hypoxic stimulation. Methods Sixty-eight patients who were diagnosed with CRSwNP from June 2015 to January 2018 at China-Japan Union Hospital of Jilin University were analyzed, including 36 males and 32 females, aged (45.2±12.5) years. [https://www.selleckchem.com/products/tween-80.html Tween 80 mouse] Nasal polyps mucosa was included in CRS-NP group and inferior turbinate mucosa was included in CRS-IT group. According to the degree of eosinophil infiltration in histopathologic results, each of these two groups was further divided into eosinophil infiltration and non-eosinophil infiltration as Eos-NP group (n=34), Non-Eos-NP group (n=34), Eos-IT group (n=20) and Non-Eos-IT group (n=20). The inferior turbinate mucosa of twenty-five patients who were diagnosed with cyst of paranasal sinus or deviation of nas localization. This illustrates the proteins above are involved in transcription and regulation of the gene responsible for the pathogenesis of CRSwNP.Objective To investigate the clinical characteristics, diagnosis, endoscopic surgical procedures, and therapeutic effect of blunt laryngeal trauma with arytenoid injury. Methods We retrospectively reviewed 12 patients who suffered blunt laryngeal trauma with laryngeal mucosa avulsion and arytenoid region injury at the Department of Otorhinolaryngology Head and Neck Surgery, Beijing Tongren Hospital from April 2007 to December 2018. Among the 12 patients, 10 were males, 2 were females, aged from 7 to 48 years old, with a median age of 21 years old. All patients were performed with transoral endoscopic laryngeal microsurgery under general anesthesia. Clinical characteristics, laryngoscopic signs, laryngeal CT, endoscopic surgical findings and procedures, and therapeutic effect were analyzed. The subjective and objective parameters of the voice quality of patients before and after surgery were compared using SPSS 22.0 statistical software by paired T test. Results All patients had a history of obvious dysphonia d be evaluated if there is obvious hoarseness, vocal fold immobility, avulsion of ventricular/vocal folds mucosa, or structural abnormality of arytenoid region under laryngoscopic examination. For highly suspected cases, microrphonosurgery under the direct laryngoscope should be performed as soon as possible, which can effectively reduce the occurrence of vocal fold movement disorders and laryngeal scar/stenosis, reconstruct the normal laryngeal structure, and restore the vocal function.Objective To investigate the histopathological and hematological changes in reoperation of recurrent chronic rhinosinusitis with nasal polyps (CRSwNP). Methods A total of 41 patients with CRSwNP who underwent two consecutive endoscopic sinus surgeries in Peking Union Medical College Hospital from February 1999 to April 2019 were included retrospectively, including 25 males and 16 females, aged (40.7±13.6) years at the former surgery and (47.0±13.2) years at the recurrent surgery. The peripheral blood cell count results were collected. Differential inflammatory cells in nasal polyp tissue sections were counted and characteristics of tissue remodeling were scored. Paired t test was used to compare the hematological and histological data of the two surgeries in the same cohort. Spearman's rank correlation coefficient was used to determine the correlation between tissue and peripheral blood eosinophil contents. Results In histopathological tissue sections of nasal polyps, the mean tissue eosinophil, lymphocyte anosinophil content correlated positively with blood eosinophil content at each surgery. Conclusions In the recurrent surgery of CRSwNP, tissue eosinophil, lymphocyte and total inflammatory cell counts decrease significantly compare with that of the former surgery. The histological inflammatory load decreases with improvement of tissue remodeling, which could be attributed to the integrated treatment with surgery and medications.Objective To explore the feasibility of reconstruction of nasal tip with septal cartilage and auricular cartilage. Methods From September 2018 to October 2019, 17 patients (two males and fifteen females) with low noses underwent rhinoplasty under general anesthesia. The age of the patients ranged from 19 to 39, with an average of 27 years old. Among them, all the 17 cases were primary rhinoplasty. During the operation, autologous nasal septum cartilage was used as septal extension graft to extend the caudal septum, and the auricular cartilage was used to enhance the stability of the strut and to elevate the tip for adjusting the shape of nose by making into spreader graft, columellar strut graft, derotation graft and onlay graft. The nasal dorsum was filled with polytetrafluoroethylene. Digital scanning technology was used to evaluate the nasal structure before and after operation. SPSS 22 software was used to analyze the data with paired t-test. Results The follow-up was from 6 to 12 months, with an avaerge of 7.6 months. Seventeen patients were satisfied with postoperative nasal morphology and height. There was no infection, prosthesis displacement, skin flap necrosis, no auricle deformation and other complications. Statistical software SPSS 22 performed paired t-test on the preoperative and postoperative data obtained by digital technology postoperative nasal length and nasal tip protrusion increased compared with that before surgery, and it was statistically significant(length(3.60±0.77)mm, tip protrusion(3.61±0.64)mm, t value was -19.203 and -23.132 respectively, both P less then 0.001). The nasolabial Angle was smaller than that before surgery, and the data were statistically significant(3.40°±2.11°,t=6.635, P less then 0.001). Conclusion The nasal tip and nasal septum extension complex constructed by autogenous nasal septal cartilage combined with auricular cartilage can increase the length of nasal tip, increase the height of nasal tip and reduce the angle of nasolabial angle.
