[Periodontal health survey and analysis of influencing factors in 916 patients with type 2 diabetes].

Purpose: To investigate the periodontal health status of type 2 diabetes patients in the Endocrinology Department of Shanghai Sixth People's Hospital, to explore relevant influencing factors of chronic periodontitis, so as to provide epidemiological basis for targeted prevention and treatment of periodontal diseases in patients with type 2 diabetes.

Methods: Periodontal examination and questionnaire survey of patients with type 2 diabetes who visited the Endocrinology Department of Shanghai Sixth People's Hospital from November 2018 to December 2018 were conducted. Criteria in "Basic Methods for Oral Health Survey" recommended by WHO was referred to check and score the relevant periodontal indicators, including probing depth, bleeding on probing, attachment loss, calculus index, plaque index, etc.

Enhanced antibacterial properties of biocompatible titanium electrochemically deposited Ag/TiO nanotubes and chitosan-gelatin-Ag-ZnO complex coating.

A novel double-layered antibacterial coating was fabricated on pure titanium (Ti) a simple three-step electrodeposition process. Scanning electronic microscopy (SEM) images show that the coating was constructed with the inner layer of TiO nanotubes doped with silver nanoparticles (TNTs/Ag) and the outer layer of chitosan-gelatin mixture with zinc oxide and silver nanoparticles (CS-Gel-Ag-ZnO). In comparison, we also investigated the composition, structure and antibacterial properties of pure Ti coated with TNTs, TNTs/Ag or TNTs/Ag + CS-Gel-Ag-ZnO, respectively.

Building texture acquisition and processing based on an unmanned airship low-altitude aerial survey system.

The traditional oblique cameras cannot self-calibrate to complete the three-dimensional (3D) modeling to meet high mapping accuracy requirements. We propose an oblique combined camera system, called a texture camera, aboard an unmanned airship that can simultaneously obtain a single vertical image and four oblique images of an object. The images acquired by this self-calibrating camera system can be used to produce traditional products on a large scale.
