In order to obtain the normal gait for the prosthesis-carrier with the change of external environment and gait, we designed a model of dynamic ankle prosthesis and control system and introduced the strategy of central pattern generator (CPG) about the moving trail of dynamic ankle prosthesis. The dynamic parts, which are incorporated in the model of dynamic ankle prosthesis, provide power in order to have anthropic function and character. The tool of Matlab/simulink was used to simulate the strategy. The simulation results showed that the strategy of CPG learn- ing control in this study was effective and could track the reference trail rapidly and fit the moving trail of a person's normal limb. It can make the prosthetic timely regulation and action, enhance the prosthetic intelligence. It has im- portant practical value for intelligent prosthesis development based on this analysis of technology.

Meridian, collateral and acupoints is the basic course of acupuncture and moxibustion and even is the core for training excellent acupuncture physician. Associated with the characters of international students, the writers had the preliminary exploration and practice on teaching this course. For the acupoint names, the international codes of acupoints and Chinese pinyin were applied in combination and the meanings of acupoint were explained to deepen the understanding of acupoints. For acupoint location, the international standards and classical medical works were combined and the experiences in acupoint location were introduced additionally to open the approach to acupoint location. For acupoint effect, the major functions and ancient medical cases were combined to improve the learning interests. For acupoint location practice, the demonstration by teachers was combined with practice and drawing of acupoints and meridians was supplemented to consolidate the foundational knowledge.

Pulse-taking, as one of the four diagnostic methods of inspection, auscultation and olfaction, inquiry and pulse-taking, can fully embodies the characteristics of traditional Chinese medicine. Pulse-taking is the teaching key point for the international students. However, because the pulsetheory and literature is quite profound and abstract and there is a long distance between the class teaching and clinical practice, the teaching of pulse-taking is also the difficult point for the international students. Therefore, the pulse-taking teaching should focus on the interesting teaching, the culture of traditional Chinese medicine of pulse, image teaching and practice training.

Objective:To assess type C behavior in patients with oral lichen planus (OLP) in order to provide basis for clinical prevention,treatment and psychological intervention of OLP.Methods:Type C behavior scale was used on 85 OLP patients and 85 control patients,who were in accordance with the inclusion criteria,in order to investigate their type C behavior.The scale included 9 items:anxiety,depression,anger,anger toward inside (anger-in),anger toward outside (anger-out),reasoning,domination,optimism,and social support.Scores of the 9 items between OLP patients and control group were calculated under the instruction of the scale and were statistically analyzed,and OLP group was further stratified statistically by sex,reticulate-erosive-ulcerative (REU) pathological type and course of diseases,and the scores of each group were analyzed and compared.Results:Among the 85 OLP patients,there were more females,more non-erosive lesion type,and the most common site for OLP was the buccal mucosa.The scores of the type-C behavior questionnaire for anxiety,depression,anger and optimism were respectively 43.01 ± 7.47,44.02 ± 7.61,21.56 ± 5.26,22.15 ± 4.00 among the OLP patients and were 37.94 ±8.70,39.58 ±7.35,18.12 ±5.39,24.05 ±3.23 among control group,with significant differences (P ＜ 0.05 for all) between the two groups.The female OLP patients had higher anxiety,depression,anger scores (43.21 ± 6.97,44.29 ± 7.54,21.64 ± 5.09) and lower reasoning,domination,optimism scores (39.12 ±5.66,16.29 ±3.95,22.05 ±4.12) with significant differences (P ＜0.05 for all) compared with those of the female controls.The scores between male patients and male controls showed no significant difference.The patients with erosive lesions had higher anger score (22.94 ± 5.26) than that of the patients without erosive lesions (20.60 ± 5.03),with a significant difference (P ＜ 0.05).With the development of the disease,the tendency of anxiety and depression of the patients were more obvious,while optimism scores remained declining.The patients suffering more than 3 years of OLP had higher anger-toward-outside scores (17.36 ± 3.35) than the patients suffering less than 3 years of OLP (15.19±3.99),with a significant difference (P ＜0.05).Conclusion:OLP patients showed an obvious type C behavior characteristic,especially in anxiety,depression,anger and low optimism.This research provides the C behavior characteristic of OLP for further psychological consultation or intervention during OLP treatment.

Objective:To evaluate the effects of different denture cleaners on the discoloration of heat-cured denture base resin and artificial teeth.Methods:40 same specifications of the heat-curing denture base resin and 40 artificial central incisors were immerced in an acombination stain of coffee,tea and soy sauce for 4 weeks.Then specimens and artificial teeth were randomly distributed into 4 groups and soaked in Polident,Steradent,0.5％ sodium hypochlorite solution and distilled water for 4 hours respectivelly(n =10).Color differences(△E) were measured by using a colorimeter and a denture spectrophotometer before and after staining,and after cleaning.Results:Before or after staining there was no difference of △E among the groups of denture base risn or artificial teeth(P ＞ 0.05).After cleaning the denture base resin and the artificial teeth in the group of 0.5％ sodium hypochlorite solution presented higher △E than the other groups(P ＜ 0.05),in group of distilled water presented lower △E than the other groups(P ＜ 0.05).No significant difference was found between Polident group and Steradent group(P ＞0.05).The △E of the denture base resin and artificial teeth.in distilled water group before staining and after cleaning were the highest among the groups(P ＜0.05).Conclusion:0.5％ sodium hypochlorite solution,Polident and Steradent are effective in removing the discoloration from the heat-cured acrylic resin and artificial teeth.0.5％ sodium hypochlorite solution is the most effective,Polident and Steradent are the similar.

Objective To investigate the clinical outcome and treatment of portal vein thrombosis (PVT) following partial splenic embolization (PSE).Methods From April 2006 to April 2010,105patients with hypersplenism caused by cirrhotic portal hypertension were treated with PSE.Contrastenhanced abdominal computed tomography or magnetic resonance imaging was performed routinely in 60patients before PSE and 1 -3 months after PSE.PVT was detected in 10 patients on images after the procedures.After PVT was diagnosed,4 patients received anticoagulant therapy immediately,and the other 6 patients did not receive therapy.Clinical data of these 10 PVT patients were analyzed retrospectively.Results 3 of 4 patients who received anticoagulant therapy had complete or partial resolution of the thrombus,and one developed mild ascites without thrombosis progression.Of the 6 patients who did not receive anticoagulant therapy,follow-up studies (6- 48 months,mean 16.9 months) demonstrated partial clot calcification in one,thrombosis progression in 5.Among those 5 patients with thrombosis progression,two experienced hematemesis due to variceal rupture and underwent transjugular intrahepatic portosystemic shunt,2 developed cavernous transformation,extensive collateral circulation,ascites and variceal progression,and one had variceal progression with melena during the follow-up period.Conclusions PVT is a severe complication of PSE.Early diagnosis and prompt anticoagulant therapy is effective in preventing PVT.

Objective To investigate the expressions of protein kinase B (PKB/Akt) and glycogen synthase kinasc-3β in the hippocampus in mice with vascular dementia (VaD) induced by repetitive bilateral common carotid artery occlusion.Methods Forty-eight healthy adult male C57B1/6 mice were randomly allocated into 3 group:normal group,sham operation group,and model group (n =16 in each group).A mouse VaD model was induced by intermittent blocking the bilateral common carotid artery for 3 times in the model group.The sham group only separated the bilateral common carotid artery,but did not block it.The normal group did not receive any treatment.The behavioral changes of the mice were observed using the water maze and step-down tests at 4 weeks after procedure.HE staining was used to observe the histopathological changes of hippocampal tissue.The Western blotting was used to detect the expressions of Akt,p-Akt (Ser473),GSK3β and p-GSK3β (Ser9) proteins.Results In the water maze test,the time of swimming the entire distance was prolonged at the learning stage and memory stage (learning stage:F =19.389,P ＜0.05; memory stage:F =27.929,P ＜ 0.05),the number of errors increased (learning stage:F =7.228,P ＜ 0.05; memory stage:F =21.189,P＜0.05) in the model group.In the step-down test,the response time was prolonged (F=19.162,P ＜0.05) at learning stage and the number of errors increased (F =6.562,P ＜ 0.05),the latency time was shortened (F=10.634,P＜0.05) and the number of errors increased (F=12.890,P＜0.05) in the model group.At the same time,HE staining showed the reduction of neurons and the proliferation of glial cells in the hippocampal CA1 region in the model group; p-Akt (Ser473) (F=37.849,P＜0.05) and p-GSK3β (Ser9)(F =67.725,P ＜0.05) protein expressions were up-regulated significantly (F =37.849,P ＜0.05; F =67.725,P＜0.05) at 4 weeks after procedure compared to those in the sham operation group,while there were no significant differences in Akt (F =1.004,P ＞0.05) and GSK3β(F =0.329,P ＞0.05) total protein expressions among all groups.Conclusions The repetitive bilateral common carotid artery occlusion may result in learning and memory impairment and severe damage in the hippocampus in mice.The Akt and GSK3β expressions may be involved in the mechanism of VaD.

Onset with fever and back pain, an 81-year-old man had sudden oliguria and progressively elevated serum creatine from normal range to 660 μmol/L within 1 week after receiving contrast agents, various antibiotics, and several nonsteroidal anti-inflammation drugs. Urine output recovered after supportive treatment. However, his serum creatinine level rose again soon after a temporary decline accompanied by gross hematuria with almost normal morphology, nephrotic proteinuria, and hypoalbuminemia. Renal biopsy revealed necrotizing glomerulonephritis. Methylprednisolone was intravenously administrated 500 mg per day for 3 days, followed by oral glucocorticoids and cyclophosphamide. Gradually the patient′s serum creatinine descended to 144 μmol/L.
