To review the recent progress about the anatomical and radiographical studies of bifid mandibular canal (BMC) in English literature recorded in PubMed from 2006 to 2015 to deepen our understanding of BMC. A BMC is an anatomical variation of the mandibular canal; its occurrence might be a result of the incomplete fusion of mandibular canal during prenatal development. The four types of BMC have been classified according to anatomical location and configuration. Characteristic radiographic features and identifying methods of BMC on panoramic radiography and cone beam computed tomography (CBCT) were described; the visibility of BMC on panoramic radiographs and CBCT images was compared. Clinical value of identifying the location as well as the configuration of BMC for surgical procedures that involve the mandible was discussed.

Objective: To investigate the delay in identification, healthcare-seeking, and definitive diagnosis of tuberculosis among students in Urumqi City from 2010 to 2019, and to identify the influencing factors, so as to provide insights into tuberculosis control among students. Methods: The demographic and diagnosis data of tuberculosis patients in Urumqi City from 2010 to 2019 were captured from the Tuberculosis Information Management System of Chinese Disease Control and Prevention Information System. The delay in identification, healthcare-seeking and definitive diagnosis of tuberculosis was analyzed among students, and the factors affecting the delay in identification, healthcare-seeking and definitive diagnosis of tuberculosis were identified using a multivariable logistic regression model. Results: A total of 996 tuberculosis cases were identified among students in Urumqi City from 2010 to 2019. There were 702 students with delay in identification of tuberculosis (70.48%), 500 students with delay in healthcare-seeking (55.22%) and 534 students with delay in definitive diagnosis (53.61%). Multivariable logistic regression analysis identified active identification (OR=0.116, 95%CI: 0.032-0.420) as a factor affecting delay in identification of tuberculosis, women (OR=1.424, 95%CI: 1.104-1.836), non-local household registration (OR=1.311, 95%CI: 1.016-1.694) and active identification (OR=0.232, 95%CI: 0.064-0.848) as factors affecting delay in healthcare-seeking, and active identification (OR=0.143, 95%CI: 0.032-0.644) as a factor affecting delay in definitive diagnosis of tuberculosis among students. Conclusions There is a high proportion of delay in identification, healthcare-seeking and definitive diagnosis of tuberculosis among students in Urumqi City from 2010 to 2019, and female and non-locally household-registered students were at a high risk of delay in healthcare-seeking for tuberculosis. Active detection and screening of tuberculosis should be reinforced.

Semiconductor quantum dots (QDs) are a new kind of biological fluorescence material, which has many advantages, such as broad excitation spectra, tunable emission spectra and good photostability. In the field of biomedical detection, the problems encountered in the traditional organic dye-based biomedical detections, such as short fluorescence lifetime and failure to simultaneous excitation of multiple colors, can be solved by using QDs. Water-soluble QDs combined with specific bio-molecules can label targeting bio-compound, which is useful in bio-molecule detection, cell labeling, tissue imaging, and can be used in fluorescence resonance energy transfer (FRET) technology. Combining QDs and protein chip technology to develop a new technology to detect multiple kinds of tumor markers will be one of the promising clinical applications of QDs with greater sensitivity, specificity, rapidity and convenience.

OBJECTIVE To explore the outcomes of CO2 laser assisted stapedotomy with artificial stapes prostheses in the treatment of advanced otosclerosis. METHODS Between January 2010 and January 2014, 15 patients (16 ears) diagnosed as advanced otosclerosis accepted CO2 laser assisted stapedotomy with artificial stapes implantation in our department. The averaged preoperative air conduction threshold of the speech frequency was 70.21 dB HL, the averaged bone conduction threshold was 38.49 dB HL, the averaged air-bone gap (ABG) was 31.72 dB HL. All cases were followed up for more than 6 months after operation. RESULTS All cases accepted auditory follow up after 6 months postoperatively. The speech frequency average air conduction threshold was 43.7 dB HL, the average bone conduction threshold was 28.95 dB HL, the average ABG was 14.75 dB HL. The ABG≤20 dB was achieved in 9 ears (56.3%) and ABG closure (≤10 dB) was achieved in 6 ears (37.5%). No cases appeared intractable vertigo, sensorineural hearing loss, secondary facial paralysis and other serious complications. CONCLUSION CO2 laser assisted technique reduced the probability of serious complications of stapedotomy, most patients with hearing level improved significantly. It's a safe, practical, relatively economical choice for advanced otosclerosis.
