Effects of individualized therapeutic porgram with heatreinforcing needling in combination with Bobath therapy on gross motor dysfunction in children with cerebral palsy:a randomized controlled trial

Objective To explore the effect of heat-reinforcing acupuncture combined with Bobath rehabilita on training for the gross motor func on measurement（GMFM） in children with cerebral palsy. Methods Sixty cases of cerebral palsy were randomized into a heat-reinforcing acupuncture combined with rehabilitation training group（group A） and a rehabilitation group（group B）,30 cases in each group. Rehabilitation training was applied in group B and heat-reinforcing acupuncture was added in group A. Jiāji（夹脊 EX-B 2）,Jiānyú（肩髃 LI 15）,Qūchí（曲池 LI 11）,Hégi（合谷 LI 4）,Yánglíngquán（阳陵泉 GB 34）,Yīnlíngquán（阴陵泉 SP 9）,Xuánzhōng（悬钟 GB 39）,Zúsānli（足三里 ST 36）,Sānyīnjiāo（三阴交 SP 6）,Chéngshān（承山 BL 57）,Tài chōng（太冲 LR 3）,Tàixī（太溪 KI 3） and Shénmén（神门 HT 4） were chosen in group A and the heat-reinforcing acupuncture was applied once a day. For scalp acupuncture,Biihuì（百会 GV 20）,Sìshéncōng（四神聪 EX-HN 1）,Zhìsānzhēn（智三针）,Nǎosānzhēn（脑三针）,Nièsānzhēn（颞三针） and motor area（运动区） were punctured without any manipulation,once every other day,3 months as a treatment course and 2 courses were needed. GMFM were selected to assess the children with cerebral palsy before treatment,a er 3 months treatment and a er 6 months treatment. Results The total eff ec ve rate in group A was 70.00%（21/30）,which is superior to that of 60.00%（24/30） in group B（P0.05）. In group A,the GMFM scores of decubitus position and turn-over of body,creeping and kneeling,sitting,standing,walking,running and jumping after6 months treatment were significantly improved compared with that before treatment and after 3 months treatment（all P0.05）. In group B,above indices a er 6 months treatment were significantly improved compared with those before treatment,the standing score after 6 months treatment was significantly improved compared with that a er 3 months treatment（P0.05）; the GMFM scores of creeping,kneeling,sitting,standing,walking,running and jumping after 6 months treatment in group A were more significantly improved than that in group B（all P0.05）. Conclusion The heat-reinforcing acupuncture combined with Bobath rehabilita on training has a be er eff ect than rehabilitation training on the GMFM scores of creeping and kneeling,si ng,standing,walking,running and jumping of children with cerebral palsy. It can be shown that the combination of heat-reinforcing acupuncture and Bobath rehabilita on training can improve the gross motor func on of children with cerebral palsy.

Modeling, measurement and simulation of the disturbance torque generated via solar array drive assembly

The disturbance torque generated via solar array drive assembly(SADA) can significantly degrade the key performance of satellite.The discussed SADA is composed of a two-phase hybrid stepping motor and a set of two-stage straight gear reducer. Firstly, the vibration equation of the two-phase hybrid stepping motor is established via simplifying and linearizing the electromagnetic torque.Secondly, based on the vibration equation established, the disturbance torque model of SADA is created via force analysis and force system simplification. Thirdly, for precisely ground measuring the disturbance torque aroused by SADA, a measurement system,including a strain micro-vibrations measurement platform(SMMP) and a set of gravity unloading device(GUD), is designed.Fourthly, the proposed disturbance torque model is validated by measuring and simulating the disturbance torque produced via SADA driving rigid load through GUD. The results indicate that, the proposed disturbance torque model holds the ability to describe the disturbance torque caused by SADA with high precision. Finally, the disturbance torque emitted by SADA driving a flexible load, designed to simulate solar array, is modeled and simulated via using fixed-interface mode synthesis method(FIMSM). All the conclusions drawn from this article do have a meaningful help for studying the disturbance torque produced by SADA driving solar array on orbit.

Analysis on Beijing's Policy of Restricting Motor Vehicle Usage

Along with the increase of car ownership,the problem of traffic congestion has appeared more and more serious since the 1990s in Beijing.In order to deal with the problem of traffic congestion,the policy of restricting motor vehicle usage,as a measure of transportation demand management by decreasing the total number of on-road motor vehicles,was firstly implemented in 2006 in trial,which continued from 2008 during the period of Olympic Games up to day.Starting with an analysis on policy motivation,this paper describes the practices of restricting motor vehicle usage in Beijing since 2006,analyzes the effects on the performance of the city's transportation,and concludes after a comparative analysis that,in spite of the positive effects on relieving the traffic congestion,the policy of restricting motor vehicle usage could only constitute a temporary measure of traffic demand management,rather than a fundamental one,because the comprehensive effects would decrease along with the continuous growth of motor vehicle possession.

Therapeutic Observation on Treatment of Infantile Cerebral Palsy with Integrative Chinese-Western Medicine： A Clinical Report of 104 Cases

Abstract Objective： To study the therapeutic effects of combined treatment with Chinese and western medicine in children with cerebral palsy （CP）. Methods： 104 CP children were treated mainly with physiotherapy and acupuncture, together with occupational therapy, sensory integration and electrical stimulation. Gross Motor Function Measure （GMFM） was used to assess the effects of treatment. Results： After treatment for 3.29＋0.80 months, the majority of CP children improved their IQ and limb symptoms, with decreased abnormal posture, increased muscle strength and improved motor developmental function. GMFM88 and GMFM66 scores had significantly increased after treatment. Conclusions： Combined treatment with Chinese and Western Medicine has confirmed effects on CP children.

Experimental Analysis and Optimization of Timing Belt Guide Plate Material on Engine Operational Friction Loss

We focus on the friction loss measurement and reduction of the timing belt guide plates of a fourcylinder gasoline engine. To minimize the friction loss caused by the dynamic friction of the guide plates during timing belt motion and improve the efficiency of the internal combustion engine(ICE), we adopt four different plastic materials in fabricating the guide plates. With controlled engine boundary conditions and operational modes, an AVL electric dynamometer is used to measure the output of the engine. The results indicate that selecting polytetrafluoroethylene(PTFE) as the additive in fabricating the guide plates can effectively reduce the friction loss, so that the output torque and output power of the engine can be improved, thus reducing fuel consumptions. This work also has positive impact on the efficiency optimization of similar ICEs.
