The purpose of this study was to examine whether functional polymorphisms in the cytochrome P450 (CYP) enzyme genes affect the risk of developing larynx and hypopharynx squamous cell carcinoma (SCC). We investigated CYP1A1, CYP1B1, CYP2E1, and CYP3A4 polymorphisms in 278 patients with laryngeal and hypopharyngeal SCC and 278 control subjects by polymerase(More)
BACKGROUND Anterior glottic web is one type of laryngeal stenosis. Previous surgical methods had some drawbacks, such as large surgical trauma, long postoperative recovery time, and multiple-stage surgery. This study aimed to explore better treatment to repair anterior glottis web. METHODS We performed vocal cord mucosal flap procedure on 32 patients with(More)
Functionalized fullerenes with specific physicochemical properties have been developed for cancer diagnosis and therapy. Notably, metallofullerene is a new class of magnetic resonance imaging (MRI) contrast-enhancing agent, and may have promising applications for clinical diagnosis. Polyhydroxylated and carboxyl fullerenes have been applied to photoacoustic(More)
A series of upconversion luminescent erbium-doped SrTiO(3) (ABO(3)-type) photocatalysts with different initial molar ratios of Sr/Ti have been prepared by a facile polymerized complex method. Er(3+) ions, which were gradually transferred from the A to the B site with increasing Sr/Ti, enabled the absorption of visible light and the generation of high-energy(More)
OBJECTIVES To describe an individual with recurrent respiratory papillomatosis that extended into the lung parenchyma and underwent malignant transformation and to discuss the characteristic imaging findings associated with this condition. METHODS The clinical presentation of an individual with this unusual malignant transformation was reviewed. A(More)
Surface molecular imprinting in layer-by-layer (SMI-LbL) film is known as a facile and effective strategy to build imprinting sites that are more accessible to template molecules compared with molecular imprinting in polymers. Herein, we accomplished the formation of SMI-LbL film on electrospun nanofibers for the first time. The SMI-LbL nanofibers were(More)
To assess the association between sequence variants of human papillomavirus (HPV) 11 and recurrent respiratory papillomatosis and the taxonomy and evolutionary history of HPV 11. Complete HPV 11 nucleotide sequences were sequenced by Illumina HiSeq2000 Analyzers and compared with the HPV 11 prototype isolate (GenBank accession number: M14119) using Blast(More)
CONCLUSION The first step when treating newborns and infants with hoarseness and dyspnea is to consider the possibility of CLSCs. The appropriate operation can then be chosen based on the cyst sub-type. Complete resection of the cyst wall is the key to preventing recurrence. BACKGROUND A laryngeal saccular cyst is an unusual congenital lesion that appears(More)
OBJECTIVE To investigate the clinical characteristics of Parkinson's Disease (PD) patients with constipation and explore the correlation between constipation and motor symptoms. METHODS The demographic data of outpatients with PD in our hospital was collected. According to Rome Ⅲ criteria, we evaluated the status of constipation in PD patients. Unified(More)
OBJECTIVE To analysis the clinical characteristics of tracheotomies children with Juvenile-onset recurrent respiratory papillomatosis (JORRP) and to discuss the time of decannulation. METHOD Thirty-one children with JORRP, who underwent tracheotomy and treated with CO2 laser in Otorhinolaryngology department of Tongren Hospital between 1993 and 2005, were(More)
