To summarize and analyze the feasibility, safety and efficacy of parapharyngeal space surgery assisted by coblation and endoscopic system with transoral approach. The data of 20 patients with parapharyngeal space tumors were retrospectively analyzed. All the patients underwent CT and/or MRI examination before surgery, and all underwent transoral approach assisted by coblation and endoscopic systems. The patients were followed up strictly after the operation, with a follow-up time of 8-56 months and the median follow-up time of 28 months. Among the 20 patients, 18 (90%) were pathologically benign tumors and 2 (10%) were malignant tumors. The maximum tumor diameter was (4.4±1.6) cm, the operative time was (79.00±30.03) min, the intraoperative blood loss was (23.63±22.20) mL, and the postoperative pain VAS score was 2.8±1.4. There were 17 cases complete resection, and 3 cases of relapse, including 1 patient who died after distant metastasis of synovial sarcoma postoperative complications occurred in 2 cases, hoarseness in 1 case of neurofibroma and tongue extension deflection in 1 case of schwannoma. Coblation assisted endoscopic system for the treatment of parapharyngeal space tumors with transoral approach has no cervical scar, which is a satisfaction for the patients, less intraoperative bleeding, short operative time, mild postoperative reaction and quick recovery. However, external approach is still recommended for primary malignant lesions, extensive or highly vascularized lesions, tumors located on the lateral side of the internal carotid artery, less than 2 cm from the skull base, or lateral invasion of the deep lobe of the parotid gland, or a pleomorphic adenoma is considered or is found to be too large to be completely resected preoperatively or intraoperatively.

Liver tumor detection and segmentation using kernel-based Extreme Learning Machine.

Annu Int Conf IEEE Eng Med Biol Soc 2013 ;2013:3662-5

This paper presents an approach to detection and segmentation of liver tumors in 3D computed tomography (CT) images. The automatic detection of tumor can be formulized as novelty detection or two-class classification issue. The method can also be used for tumor segmentation, where each voxel is to be assigned with a correct label, either a tumor class or nontumor class. A voxel is represented with a rich feature vector that distinguishes itself from voxels in different classes. A fast learning algorithm Extreme Learning Machine (ELM) is trained as a voxel classifier. In automatic liver tumor detection, we propose and show that ELM can be trained as a one-class classifier with only healthy liver samples in training. It results in a method of tumor detection based on novelty detection. We compare it with two-class ELM. To extract the boundary of a tumor, we adopt the semi-automatic approach by randomly selecting samples in 3D space within a limited region of interest (ROI) for classifier training. Our approach is validated on a group of patients' CT data and the experiment shows good detection and encouraging segmentation results.

[The application of mitomycin C in treatment of airway scarring stenosis].

Lin Chung Er Bi Yan Hou Tou Jing Wai Ke Za Zhi 2013 Jun;27(12):654-6

Department of Otolaryngology, the First Affiliated Hospital of Nanjing Medical University, Nanjing, 210029, China.

Objective: To explore the feasibility and efficacy of mitomycin C(MMC) in the treatment of airway scarring stenosis.

Method: The clinical materials of 11 patients with airway stenosis treated with MMC from 2008 to 2012 were analyzed retrospectively,including atresiaofnasopharynx/choanal atresia (2 cases), pharyngostenosis (1 case), and laryngotracheal stenosis (8 cases). All were treated with endoscopic surgery under general anesthesia. Patients received topical application of MMC (0.4 mg/ml) to the lesion for 5 minutes after the scar tissue removed and repeated five times.

Result: No patients occurred restenosis in 2 months' follow-up postoperative. Two patients with atresiaofnasopharynx/choanal atresia achieved satisfactory ventilation outcome, 8 patients with laryngotracheal stenosis decannulated successfully, 1 patients with pharyngostenosis achieved near normal deglutition.

Conclusion: MMC in endoscopic airway surgery is safe and effective in the treatment of airway stenosis and offers a high success rate for patients with grade 1-2 stenosis. It should be used as a first method in the treatment of airway stenosis.

Mometasone furoate nasal spray reduces symptoms and improves quality of life in Chinese patients with moderate to severe allergic rhinitis: a multicenter open-label study.

Acta Otolaryngol 2009 Dec;129(12):1463-8

Department of Otolaryngology Head and Neck Surgery, Beijing TongRen Hospital, Key Laboratory of Otolaryngology Head and Neck Surgery, (Capital Medical University), Ministry of Education, Beijing Institute of Otolaryngology, Beijing, China.

Conclusion: Mometasone furoate nasal spray (MFNS) can reduce the symptoms and improve quality of life in Chinese patients with moderate to severe allergic rhinitis (AR).

Objective: To evaluate the effects of MF on symptoms and quality of life in Chinese patients with moderate to severe AR.

Patients And Methods: In a multicenter and open-label study, 500 patients with moderate to severe AR were enrolled and received MFNS 200 microg once daily. We visited the patients four times (at baseline, and week 1, 2, and 4) to record symptom scores and the influence of AR on daytime activities and quality of sleep. The Mini Rhinoconjunctivitis Quality of Life Questionnaire (Mini-RQLQ) and the Nocturnal Rhinoconjunctivitis Quality of Life Questionnaire (NRQLQ) were used in this study.

Results: Compared with the baseline, MFNS significantly reduced the total and individual symptom scores and nocturnal sleep and daytime activities scores at week 1, 2, and 4 according to the Mini-RQLQ and NRQLQ.
