Three kinds of biomedical materials of stomatology were introduced,including metal materials,polymers and non-metal bio composites.The literatures related to stomatology biomedical materials from 2008 to 2015 were collected in PubMed medical literature retrieval service system,and then statistical method was used to analyze the literature number,the numbers of literatures on different materials as well as the nations distribution.Composite,intelligent and functional materials were pointed out to be taking the place of metal materials,and thus might extend their clinical application in the future.

Objective To design a vision-based detection method for rotated human bodies to fulfill unmanned wounded search in the rescue operation.Methods HOG (histogram of oriented gradient) which was the most successful visual feature in pedestrian detection was involved in,and the human detection in the wounded search task was realized by multi-directional detection.Furthermore,two human bodies datasets were established by imitating the views of unmanned ground vehicle (UGV)and unmanned aerial vehicle (UAV).Results The application to the two datasets proved the method's feasibility in UGV and UAV.Conclusion The method is robust to the in-plane rotations and out-plane rotations of human bodies,which is of vital significance to promote the efficiency of the wounded searching and rescuing.

Objective To investigate the influencing factors on thrombin time (TT) assay to ensure the accuracy of the detection results.Methods Totally 3 out-and in-patients from January to July 2015 with normal results of prothrombin time (PT),activated partial clotting enzyme live time (APTT) and fibrinogen (FIB) were selected,whose detection results were not satisfactory.The specimen underwent re-centrifugation,and then Beckman ACL TOP700 automatic coagulation analyzer was used to detect four coagulation indexes.The detection results were compared with those before re-centrifugation,and the differences between the results were analyzed statically.Results The values of PT,APTT and FIB of the three patients before and after re-centrifugation were (10.8,11.5,9.7 s),(29.5,32.7,25.2 s),(2.49,3.12,2.85 g/L) and (10.9,11.3,10.0 s),(30.4,31.5,25.9 s),(2.31,3.28,2.67 g/L) respectively,and the differences between the results were not significant (with t ranging from 0.627 to 1.719 and P＞0.05).The values of TT of the three patients before and after re-centrifugation were (66.51,127.3,89.62 s) and (12.2,15.7,13.8 s) respectively,and there were obvious differences between the values (with t ranging from 51.743 to 79.167 and P＜0.001).Conclusion Insufficient centrifugation has high influences on the detection result of TT except other coagulation indexes,and re-centrifugation is necessary for the accuracy of TT value to eliminate misdiagnosis.

Objective To investigate the impacts of water supply on water quality in the pipeline of the dental comprehensive treatment platform to contribute to pollution control.Methods Totally 8 platforms from the stomatological department underwent 2-a detection and tracing.The water sources included tap water,distilled water and filtered water,and the discharge water went through sampling and bacteriological analysis before and after disinfection.Results The mean numbers of colonies by tap water,distilled water and filtered water were (472±385),(380±372) and (446±382) cfu/ml respectively,and the qualification rates by tap water,distilled water and filtered water were 33.3％,45.8％ and 37.5％ respectively.All the colonies numbers were limited within 0 and 60 cfu/ml with the qualification rate being 100％ after disinfection.Conclusion Water source cannot relieve bacterial infection effectively,and disinfection eliminates bacteria and improves water quality in the pipeline of the dental comprehensive treatment platform.

Objective To study the clinical curative effect of small needle knife combined with manipulation on adhesive capsulitis.Methods Totally 120 adhesive capsulitis patients treated from March 2014 to November 2015 were enrolled in the study,and divided into a treatment group and a control group randomly and equally.The patients in the treatment group were treated with small needle knife combined with manipulation,and the ones in the control group took anti-inflammatory analgesics orally.The changes of shoulder joint pain and function scores as well as the clinical effects were observed and compared in the two groups.Results The treatment group behaved significantly better than the control group in the indexes of shoulder pain,pressing pain,nyctalgia,internal and external rotation,adduction,abduction and etc (P＜0.05).The total effective rate was 93.3％ in the treatment group,which was obviously higher than that (68.3％) in the control group (P＜0.05).Conclusion The curative effect of combined manipulation and small needle knife gains advantages over oral antiinflammatory analgesics when used to treat adhesive capsulitis patients,and thus is worthy promoting practically.

Objective To explore the application effect of a new lighted surgical aspirator in deep brain hematoma removal operation.Methods Totally 153 patients of non-traumatic basis festival area cerebral hemorrhage were randomly divided into a control group and a treatment group.Both the groups underwent clearance of intracranial hematoma and decompressive craniectomy surgical operation in the operating room,with the common aspirator involved in the control group and the lighted one in the treatment group.Results There was no significant difference between the rates of hematomal removal in the groups (P＞0.05).The treatment group had the operating time less by 59.85 min and the hospital stay decreased by 15.23 d than those in the control group (P＜0.05).The GOS score and daily viability of the treatment group was also statistically higher than those of the control group (P＜0.05),and the effective rate in the treatment group was also more than that in the control group by 24.9％ (P＜0.05).Conclusion The new aspirator solves the problems in visual field and light source,decreases the operating time and improves the disease prognosis.

Objective To apply color Doppler flow imaging (CDFI) and transcranial Doppler (TCD) to the follow-up observation of the changes of cervical vessel,intracranial hemodynamics and cerebrovascular reserve capacity (CVR) of the patients after carotid artery stent implantation.Methods Totally 96 patients with carotid artery stent implantation underwent CDFI and TCD examinations,and the changes of hemodynamics were compared before and 1 month,6 months,1 a and 2 a after implantation.Results The values of peak systolic velocity (PSV) and resistance index (RI) at the areas of carotid stenosis were lower significantly than those before implantation,while the values of PSV,pulsatility index (PI) and CVR of the middle cerebral artery were obviously higher than those before implantation (P＜0.05).There were no significant differences between the cervical and intracranial hemodynamics indexes 1 month,6 months,1 a and 2 a after treatment.Two-year follow-up found 4 cases of restenoses after implantation,and the rate for restenosis was 4.2％.Conclusion Carotid artery stent implantation improves significantly cervical and intracranial blood supply as well as CVR of the carotid stenosis patient,and CDFI combined with TCD can be used for the accurate evaluation of the efficacy and postoperative follow-up of carotid artery stent implantation.
