This paper discussed the application of upper extremity rehabilitation devices in rehabilitation evaluation after stroke, focused on some typical kinds of upper extremity rehabilitation systems. It was analyzed that the way to obtain multiple parameter and evaluation indices during the progress of upper extremity rehabilitation evaluation, and viewed the development and application of upper extremity rehabilitation evaluation technology.

It is very difficult for stroke patients to complete the action of squatting-standing because their equilibrium function ability has been seriously declined. It was necessary, therefore, to do a deep research on the action of human squatting-standing and to set up an accurate model and simulation. In our modeling research, the movements of upper limbs and head was neglected, and a seven-segment model was developed to establish the coordinate system of human squatting-standing action. It calculated the knee joint moment and hip joint moment during squatting and standing by utilizing Lagrange method, and then simulated this mathematical model by utilizing Matlab. Geometric model of human squatting-standing was developed and simulated in ADAMS which proved that the established Lagrange model was reasonable. It would also provide significant theoretical references for further study and development of squatting-standing rehabilitation training equipment.

Objective To know the epidemiological characteristics of hand-foot-mouth disease in Yangpu District and provide evidence for specific strategies and measures of hand-foot-mouth disease activity prevention and control. Methods Descriptive analysis of the data from hand-foot-mouth disease epidemic situation in Yangpu District from 2005 to 2008 was made. Results 1 348 cases were reported in the whole Yangpu District from 2005 to 2008, and no severe cases, no death. The average morbidity in Yangpu District was 27.48/100 000. The male to female ratio was 1.46∶1. The infection occurred to infants aged from 1 year to 5 years (85.39%). The incidence of the native population children aged 2 to 3 exceeded 10/100 000. The season peak appeared from May to July (70.18%), and outbreaks used to occur at nurseries and kindergartens. The typical clinical presentations mainly included fever and rash. The rash mainly occurred to hands, feet, mouth, buttocks and so on. Conclusions Incidence varied significantly between different sexes, seasons and ages. It can cause large-scale epidemic in a short period of time, the epidemic was very difficult to control, but the leaders attach importance to take the early warning and monitoring, accuratey deal with emergencies, health education promotion and training of comprehensive measures, the epidemic can be effectively controlled.

Obstacles in pharyngoesophageal function are characterized clinically by dysphagia.At present,the treatment for dysphagia is broadly divided into two ways:balloon expansion therapy and electrical stimulation therapy.Balloon dilatation device for achalasia of cricopharyngeal muscle is design based on the principle of expansion treatment to stimulate cricopharyngeal muscle contraction and dilatation through the pressure of balloon dilation.At work,the water was filled in balloon catheter through the electronic charge pump to pressurize to reach a certain pressure of the balloon dilatation,and the drain valve drained water at prescriptive speed until it reaches a certain contraction of the balloon pressure,followed by water filling in the balloon catheter.This operation was repeated operation,resulting in a compression cycle to cricopharyngeal muscle,promote its contraction and dilatation.Patients can gradually restore autonomy of swallowing.The device is easy to operate,safe and reliable.The doctor can fill water in the balloon catheter at certain time and quantity to achieve the treatment of achalasia of cricopharyngeal muscle.

Mirror therapy has been widely used in practice as an effective rehabilitaiton method. Mirror integrated therapy combined mirror therapy with some other technologies, such as virtual reality, functional electrical stimulation, augmented reality, etc., to enhance the task orientation, and improve the efficiency of treatment.

Objective:To investigate the effects of paeonol on aortic nuclear factor-kappaB ( NF-κB) activity and blood lipid levels in the rats with atherosclerosis ( AS) . Methods:The AS rat model was established by administration of high-fat diet and vitamin D3 ( i. p. ). The rats were divided into 5 groups (n=8) randomly, namely the normal group, model group, positive control group(simvasta-tin, 10 mg·kg-1 ) and paeonol groups with the dose of 20 and 10 mg·kg-1 , respectively. After the 4-week treatment, the serum of rats was collected to determine the lipid levels. The aortic pathologic changes of AS rats were observed under a microscope, and then graded, and aortic NF-κB activity was detected by an immunohistochemistry method. Results:Administration of paeonol improved the severity of aortic pathology in AS rats. The pathologic grade in the paeonol group (20 mg·kg-1 ) showed a significant difference com-pared with that in the model group (P<0. 05). Paeonol (20 and 10 mg·kg-1) markedly decreased the TG, TC and LDL-C levels in the serum of AS rats (P<0. 05 or P<0. 01). Meanwhile, paeonol significantly inhibited the aortic NF-κB activity(IOD value) with (1. 96 ± 0. 55) and (2. 50 ± 0. 80) in 20 and 10 mg·kg-1 group, respectively, which showed significant differences compared with that in the model group (P<0. 05 or P<0. 01). Conclusion:Paeonol shows certain therapeutic effect in AS rats, and the mechanisms may be related with the regulation of lipid mobilization and the inhibition of aortic NF-κB activity.
