Hip-stressed lower limb specific strength training apparatus is a new kind of training equipment with the combination of specific technical strength training and quantitative evaluating. Base on the mechanism of sports physiology and sports biomechanics, by applying the theory of motor learning and control, the apparatus adopts the training model of the "hip stress loading device" and "hip-feet starting and ending stress point" to simulate the track of working limb in running, jumping and throwing, controls the degrees of body movement freedom reasonably. For the first time, actualizes the heavy load specific strength and sports skill training of leg driving, leg pawing and trunk-backward knees-bend leg driving. The distinctive training pattern of forced track control and the training method of strength & skill coupling" used in this apparatus, makes the action in strength training approach to real sport skill in greatest extent, and shifts the result of strength training to the skill training as much as possible. So it remarkably increase the efficiency of strength training and has an great importance in changing the concept of strength training.

ObjectiveTo assess the safety and clinical values of video-laryngoscope in spontaneous respiration tracheal intubation for emergency patients. Methods Seventy-nine patients,who needed the endotracheal intubation,were recruited in our department between January 2010 and December 2010,and were randomly ( random number) divided into two groups according to consultative sequence.Forty patients (group A ) were operated with traditional laryngoscope and thirty-nine patients (group B ) with videolaryngoscope.The operative time and success rate of tracheal intubation,Cormack-Lehane classification,as well as adverse events,were recorded.The heart rate ( HR ),mean arterial blood pressure ( MAP),respiratory rate ( RR ),and saturation of pulse oxygen ( SpO2 ) were observed pre-operation,during operation and 2 min post-operation.Results( 1 ) The Cormack-Lehane classification in group A were significantly lower than in group B. (2) The operative time of tracheal intubation in group B was significantly less than that in group A [(35.6+12.7) svs. (58.3 ± 13.5) s; P＜0.05] ; and one-time success rate of tracheal intubation in group B was higher than that in group A ( 84.6％ vs.52.5％ ; P ＜0.05).(3) Compared to group B,the HR and MAP in Group A were significantly increased at t2 and t3 ( P ＜ 0.05 ). ( 4 ) The adverse events,including restlessness,bucking and injury,were significantly decreased in group B than those in group A ( P ＜ 0.05 ).ConclusionsThe video-laryngoscope used in spontaneous respiration tracheal intubation,could improve Cormack-Lehane classification,short operative time,enhance one-time success rate and reduce adverse evevnts.

Objective To explore the mechanism of ginsenoside-Rh2(G-Rh2) on inhibition of glioma by identifying differential proteins with proteomic technique. Methods The total proteins were extracted from SHG-44 cells treated with 32 ?mol?L-1 G-Rh2 for 72 h and the cells in control group,then were subjected to two-dimensional gel electrophoresis.Only spots with a fold change equal or above 1.5 and P
