Objective:A modificated emergency medical care system was designed based on business process reengineering to offer the emergency patients a more satisfactory medical service.Methods:From Jan.to Mar.in 2005 and the same period in 2006,200 emergency patients were investigated(100 cases for each time period) in a general hospital.The data of the 100 patients acquired in 2005 were served as the control group and those of the other 100 patients acquired in 2006 were served as the research group.A series measure of emergency medical service,such as computerizing administration of the patient history,utilizing the network transmission and sharing system of pictures,automatizing price system and re-integrating auxiliary examination labs,were applied in the aim of shortening the waiting times for charging,examination,etc.Results:Better satisfaction to the advanced emergency medical service process was found in the research group.The patients' waiting times for receiving diagnosis and treatment,laboratory examinations and paying fees in the research group were statistically shortened compared to those in the control group(P

Self-ligating brackets have been developed for decades. Now more and more orthodontists are using self-ligating appliance systems, because they have the following advantages over conventional orthodontic brackets: less friction between the archwires and the brackets;simple clinical operation;comfortable for patients. This review introduces the self-ligating brackets' feature, classification and several self-ligating brackets applied in clinic.

Objective:To examine the soft tissue changes of early skeletal Class III malocclusion patients after maxillary protraction treatment. Methods:60 skeletal anterior crossbite patients, 27 males, 33 females in the late mixed dentition were selected. The age ranged from 8 to 11 years. Mean age was 9.3 years. The patients were divided into treatment group and control group. Average treatment time was 12.1 months. Pre- and post-treatment lateral cephalograms of both groups were traced and analyzed. Difference between pre- and post-treatment was analyzed with paired t-tests. Results:After treatment, Ns-Sn-Pos, Ns-Prn-Pos, Sn-S-Si and Cm-Sn-UL decreased significantly,while Sn-Ns-Si and UL-E increased significantly. No significant change was found in S-Ns-Sn and LL-E. Conclusion:Soft tissue profiles are significantly improved by maxillary protraction treatment in the late mixed dentition. The concave profiles were changed to straight or nearly normal profiles. The relationship among nose, upper lip, lower lip and chin become harmonious. The curve of the lips tends to be smooth and harmonious.

Objective To establish a three-dimensional digitized visible model to meet the clinical and research needs.Methods The head of the volunteer was scanned by a cone beam CT (CBCT).The bone tissue,the facial soft tissue and the teeth were extracted from the cone beam CT raw data according to the different Houns field values.The 3D digital craniofacial model was reconstructed from the three tissues extracted from the CBCT original data.The 3D dental model with high resolution was acquired by scanning the dental cast with the laser scanner.The 3D facial model with texture was acquired by scanning the volunteer's face directly by other laser scanner.With the regis tration algorithm in 3D graphics,the 3D facial model with texture and the 3D dental model with high resolution were transformed to the same coordinate which was of the 3D digital craniofacial model.Results We acquired a complicated 3D craniofacial digital model which combined the teeth model with high resolution,the bone model and the face model with texture.Conclusions The method is able to accurately establish the craniofacial digital model.

Objective To examine the effects of fixed appliance and micro-implant on the improvement of facial profile in patients with protruding.Methods 30 protruding cases were treated by fixed appliance and micro-implant.Cephalometric data before and after treatment were measured and analyzed to assess the effects.Results The upper incisors were retracted 6.5 mm.The upper lip was retracted 3.8 mm.The lower incisors were retracted 5.8 mm.The lower lip was retracted 5.6 mm.UL-E was retracted 3.21 mm.LL-E was retracted 3.67 mm.NLA was changed from 86.7°to 103.7°.The U1-SN,U1-Y,L1-MP,L1-Y,UL-Y,LL-Y,UL-E,LL-E,and NLA demonstrated significant differences between pre-and post-treatment.Conclusions Fixed appliance and micro-implant might retract the anterior teeth and lead to an improvement of facial profile.

ObjectiveTo explore the inflammatory factors C-reactive protein (CRP),interleukin (IL)-6,tumor necrosis factor (TNF)-α and white blood cell (WBC) count differences between acute myocardial infarction(AMI ) thrombolysis treatment and unthormbolysis treatment,and find out the relevance between the inflammatory factors and the prognosis.MethodsAccording to the condition of accepting AMI thrombolysis treatment,the 229 patients of AMI were divided into the thrombolysis group( 131 cases) and the unthrombolysis group(98 cases).The levels of myocardial troponin I (cTnI),creatine kinase(CK),creatine kinase isoenzyme-MB (CK-MB) were detected at the time of patients sent into the hospital for the immediate,6-hour later and 24-hour later.After 6-month's follow-up,prognosis was compared between two groups.ResultsTwenty-seven cases lost in the thrombolysis group.One case died within 6 months and the mortality was 1.0％(1/104) in the thrombolysis group,and 6 cases died within 6 months and the mortality was 6.1％(6/98 ) in the unthrombolysis group.There was significant difference between two groups (P ＜ 0.05 ).The levels of CK,CK-MB in the thrombolysis group advanced,and compared with that in the unthrombolysis group,there were significant differences (P ＜ 0.05 ).The levels of TNF-α,IL-6 in the thrombolysis group were significantly higher than those in the unthrombolysis group (P＜ 0.05),and CRP and WBC count had no significant differences between two groups (P ＞ 0.05).The repatency rate was 79.4％( 104/131 ) in the thrombolysis group,the levels of TNF- α,IL-6 in repatency patients were higher than those in non-repatency patients.There were significant differences(P ＜ 0.05 ).ConclusionsThe thrombolysis is an effective way to cure AMI.The increase of TNF- α,IL-6 after the thrombolysis is considered to be related to reperfusion injury,and CRP,IL-6,TNF-α and WBC count can forecast the inflammation of myocardial necrosis and take an impotant role in predicting the prognosis of the AMI.The antiinflammatory and antioxidation treatment is significant to improve the prognosis of the AMI.

Objective: To investigate the effect of enteral nutrition on proliferation of colon mucusa in long fasting patients. Methods: Ten patients fasted over two weeks were selected.All patients had no any histories of chemotherapy, radiotherapy and immunosuppressive therapy.They received enteral nutrition for tow weeks. Before and two weeks after enteral nutrition,specimens were obtained between sigmoid and descending colon by colonofibroscope.All specimens of colon mucosa were determined by FCM for proliferation index (PI),S phase factor (SPF)and aptosis(Apto). Results: PI,SPF and Apto were ( 4.010 ?1.290)%,(1.904?2.679)% and (1.913?2.021)% in patients fasted over two weeks respectively, and (7.337?2.679)%,(5.367?3.211)% and (1.208?1.488)% after enteral nutrition for two weeks. Conclusions: Enteral nutrition could improve the proliferation of colon mucosa in long fasting patients.

Objective To investigave the X-ray guided radiofrequency ablation system. Methods The ablation catheter was guided using the X-ray image so the location of electrode on top of the catheter can be fixed on. Alternating current was carried out at the focus to make the ablation. The multi-channel electrophysiology recorder was combined here to record the electrophysiology status before, during and after the surgery to ensure safety of the patient. Results One case was reviewed, which was treated with the X-ray guided radiofrequency ablation system. After the ablation, the A waves and the V wave were separated and the ablation surgery was successful. Conclusion Some simple and fast arrhythmia can be treated effectively by the above system.
