OBJECTIVETo get the information of patients' understand to the knowledge of artificial teeth prosthetics, provide reference for the propaganda of the prosthetic knowledge.

METHODS500 patients were chosen as the research objects. The survey about patients' understand to the knowledge of artificial teeth prosthetics was made with a reasonable questionnaire designed by us. The questionnaire contained nine sections. The questionnaires were filled in by the patients, dispatched and received by special messengers. The information of the questionnaires was analyzed and summarized.

RESULTS477 effective questionnaires were received. Patients were more familiar with the knowledge of the opportunity to get the oral prosthetic and less familiar with the knowledge of common problems after the oral prosthetic, the curing process before the oral prosthetic and the visiting times of the ordinary cure. However, they were not familiar with the knowledge of the basic concepts of the oral prosthetic, prosthetic materials and construction of dental prosthetic restoration and announcements after the oral prosthetic. They were most unfamiliar with the knowledge of common problems in the oral prosthetic process.

CONCLUSIONThe propaganda of the oral prosthetic should focus on the basic concepts of the oral prosthetic, prosthetic materials and construction of dental prosthetic restoration, common problems in the oral prosthetic process and announcements after the oral prosthetic. Meeting such problems, dentists should explain them to the patients patiently.

OBJECTIVE: We wanted to evaluate the image quality and diagnostic value of 64-slice dual-source computed tomography (DSCT) coronary angiography in patients with atrial fibrillation (Afib). MATERIALS AND METHODS: The coronary arteries of 22 Afib patients seen on DSCT were classified into 15 segments and the imaging quality (excellent, good, moderate and poor) and significant stenoses (> or = 50%) were evaluated by two radiologists who were blinded to the conventional coronary angiography (CAG) results. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for detecting important coronary artery stenosis were calculated. McNemar test was used to determine any significant difference between DSCT and CAG, and Cohen's Kappa statistics were calculated for the intermodality and interobserver agreement. RESULTS: The mean heart rate was 89 +/- 8.3 bpm (range: 80-118 bpm). A range from 250 msec to 300 msec within the RR interval was the optimal reconstruction interval for the patients with Afib. The respective overall sensitivity, specificity, PPV and NPV values were 74%, 97%, 81% and 96% for reader 1 and 72%, 98%, 85% and 96% for reader 2. No significant difference between DSCT and CAG was found for detecting a significant stenosis (reader 1, p = 1.0; reader 2, p = 0.727). Cohen's Kappa statistics demonstrated good intermodality and interobserver agreement. CONCLUSION: 64-slice DSCT coronary angiography provides good image quality in patients with atrial fibrillation without the need for controlling the heart rate. DSCT can be used for ruling out significant stenosis in patients with atrial fibrillation with its high NPV for detecting in important stenosis.

Objective To investigate the long-term effect of free flap in repairing hemifacial atrophy.Methods From April,1991 to April,2015,19 cases (5 males and 14 females) aged between 18 and 51 years (mean,26 years) with hemifacial atrophy were treated by free flap.Hemifacial atrophy affected the left side in 8 patients,and the right side in the remaining 11.Fifteen cases only had a hemifacial soft tissue deficit,the other 4 cases were associated with ipsilateral zygoma dysplasia,in which 1 had ipsilateral scar contracture.The latissimus dorsi muscle flap were applied in 12 cases (2 of which anastomose thoracodorsal nerve with the cervical branch of the facial nerve),the scapular flap in 2 cases,the tensor fascia latae dermal flap with dermal fat flap in 3 cases,and with iliac groin composite tissue flap and ilium groin dermal composite tissue flap in 1 case respectively.Among them,14 flaps had their blood vessels anastomosed to the superficial temporal artery and vein,and 5 to the facial artery and vein.All operations were successfuly accomplished and followed-up for 2-21 years.Results All patients had ideal clinical outcomes with significant improvement in facial symmetry and skin color,and no dysfunction happened.Conclusion The long-term effect of surgical management with free flap in repairing hemifacial atrophy is satisfactory.It is an effective method of clinical treatment.

Objective: To identify the functional connectivity characteristics of insula, sensory and social related brain regions in boys with autism spectrum disorder(ASD), to explore the central nervous basis of sensory abnormality affecting core symptoms in boys with ASD. Methods: Resting state functional magnetic resonance imaging (rs fMRI) data were collected from 34 boys with ASD and 29 typical development boys (TD group). Based on functional connectivity analysis, the sensory related brain regions, insula, and social related brain regions were taken as regions of interest to calculate the functional connectivity (FC) level between the regions of interest, the differences between the two groups were compared and the results were corrected by FDR. The Autism Diagnostic Observation Schedule (ADOS), Childhood Autism Rating Scale (CARS) and Autism Spectrum Quotient-Children s Version (AQ-Child) were used to assess the core phenotypes of boys with ASD. Results: Compared with the TD group, the levels of FC between tactile brain regions and insula, olfactory brain regions and insula, auditory brain regions and insula in boys with ASD group were significantly increased. The level of FC between the insula and bilateral amygdala，insula and the medial prefrontal cortex(mPFC) were significantly increased( P <0.05).Pearson correlation analysis showed that the level of FC between auditory brain region(BA42)and left insula in ASD group was negatively correlated with the scores of communication subscale of ADOS( r =-0.44)，social interaction subscale of ADOS( r =-0.43), communication & social interaction subscale of ADOS( r =-0.49),attention to details subscale of AQ-Child( r =-0.41). The level of FC between the right insula and right amygdala was positively correlated with the attention switch subscale of AQ-Child( r =0.38), the level of FC between right insula and mPFC was positively correlated with the scores of repetitive behavior subscale of ADOS( r =0.48), the attention switch subscale of AQ-Child( r =0.49), total scale subscale of AQ-Child( r =0.41), total scale of CARS( r =0.41)( P < 0.05 ). Conclusion The levels of FC between insula and sensory related, social related brain regions are abnormal in children with ASD, which have significant correlations with clinical symptoms. In depth studies can be conducted to explore underlying neutral mechanisms.

Objective:To analyze the research status of scleral lenses by bibliometric method based on the relevant collection of scleral lenses in the Web of Science database.Methods:Using the scleral lens-related literature collected in the Web of Science Core Collection database in the past 10 years (January 2013 to December 2022) as the object of analysis, bibliometric method and CiteSpace tools were used to conduct visual analysis of the literature.A comprehensive analysis of the volume of literature published, the distribution of countries and institutions, the information of core authors, the distribution of journals, and keyword clustering was performed.Results:A total of 340 articles were retrieved, which were published in 54 journals, with an average of 6.3 articles per journal, involving 301 authors.Research in this area covered 35 countries or regions, and 256 research institutions were involved.Discipline development was mainly in the United States, India, Spain and Australia.The main focus was on scleral lens (scleral contact lens), ocular surface disease, corneal edema, miniature scleral lens, etc.In the past 10 years, the trend of research hot topics in scleral lenses had shifted from the initial study of combining scleral contact lenses with ocular surface diseases to the subsequent study of prosthetic replacement of the ocular surface ecosystem, and the exploration of corneal clearance and shape.From 2013 to 2021, the main focuses were ocular surface diseases, scleral contact lenses, and corneal edema.After 2021, research on ocular surface diseases and keratoplasty declined.From January 2013 to December 2022, emergent keywords related to scleral lens mainly included scleral contact lens, transplantation, anti-host disease, prosthetic device in the first stage, artificial replacement of ocular surface ecosystem and irregular cornea in the second stage, and the research on corneal gap and characteristic shape in the third stage.Optical coherence tomography and corneal topography were commonly used examinations for scleral lens research and fitting.Conclusions:At present, the scleral lens is mainly used for dry eye, corneal diseases, corneal ectasia, keratitis, and corneal transplantation, especially after penetrating keratoplasty and refractive errors.Prosthetic replacement of the ocular surface ecosystem, and the exploration of corneal clearance and shape are the research hotspots in scleral lenses.
