Objective To introduce the Chinese version of short Falls Efficacy Scale International (short FES-I) and test its reliability and validity in patients with cerebral infarction. Methods The English version and the traditional Chinese version of short FES-I were ob-tained from the Prevention of Falls Network Europe, and the simplified Chinese version was developed after a further revision. A sample of 105 inpatients with cerebral infarction from December 2014 to May 2015 were recruited from 2 tertiary hospitals in Tianjin. They were in-vestigated with the simplified Chinese version of short FES-I, modified Falls Efficacy Scale (MFES), Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9). At the same time, the laboratory indexes of the patients were collected. Results The Cronbach'sαcoefficient of short FES-I was 0.98 and the score of short FES-I was negatively correlated with MFES (r=-0.41, P<0.001). Short FES-I was correlated wtih GAD-7 score (r=0.52, P<0.001), PHQ-9 score (r=0.46, P<0.001) and the level of C reaction protein (r=0.21, P=0.032), but uncorrelated with other laboratory indexes (P>0.05). There was significant difference in the score of short FES-I be-tween the patients with or without falling. Conclusion Short FES-I is valid and internal consistant, and can be used as an assessment tool to screen fear of falling among patients with cerebral infarction.

BACKGROUND: Schwann calls are seed cells for constructing tissue engineered peripheral nerves. But their in vitro isolation, culture and purification are difficult. Acellular nerve allografts (ANA) have a great effect on repairing peripheral nerve defects, and it can induce marrow stromal cells (MSCs) into Schwann-like calls. Accordingly, MSCs can be used as seed calls theoretically in constructing tissue engineered peripheral nerves, instead of Schwann cells OBJECTIVE: To observe the repairing effect of tissue engineered peripheral nerves constructed with MSCs on sciatic nerve defects and to assess the feasibility of repairing peripheral nerve defects with MSCs as seed calls. DESIGN, TIME AND SE'I-rlNG: A randomized control animal experiment was conducted in the laboratory of Basic Medicine Collage of Dali Collage from July to December in 2008.MATERIALS: A total of 30 SD rats were divided randomly into 3 groups, with 10 in each group. In MSCs+ ANA group, end-to-end anastomosis were performed with 10/0 non traumatic suture to broken ends of rat sciatic nerves and tissue engineered nerves cultured using MSCs combined with ANA; In ANA group, ANA were bridged to broken ends of sciatic nerves; In METHODS: The 10ram sciatic nerve defects in rats were repaired using MSCs-constructed tissue engineered peripheral nerves, whose repairing effects were evaluated at week 12 post transplant through sciatic function index (SFI), gastrocnemius wet weight recovery rate, S-100 immunohistochemical staining and electron microscope observation, etc. MAIN OUTCOME MEASURES: Morphological changes of calls were observed during the culture of compounds; SFI and gastrocnemius wet weight recovery rates were detected after transplantation; New myelinization, axon growth and nerve fiber distdbuUon were observed with toluidine blue staining; Schwann calls growth and nerve fiber regeneration were observed with transmission electron microscope combined with S-100 protein immunohistochemical staining method.RESULTS: The detection results showed that SFI and gastrocnemius wet weight recovery rate were higher in the MSCs+ ANA group than in the ANA group (P < 0.05). Compared the ANA group, the MSCs+ ANA group had more S-100 proteins expressed in its compounds obviously, and the number, the diameter of its myelinated nerve fibers as well as its myelin sheath thickness were all greater than those of the ANA group (P < 0.05). The repairing effect of the MSCs+ ANA group was close to that of the autotransplantation group.CONCLUSION: MSCs-constructed tissue engineered nerves have a better effect on repairing peripheral nerve defects than ANA, and MSCs as seed cells have a high value in peripheral nerve tissue engineering.

The purpose of this study was to develop a robotic system for image-guided percutaneous interventions using ultrasound (US) or computed tomography (CT) for needle biopsy, ablation, cryotherapy, and other needle procedures. The conventional operation of puncture was analyzed firstly, and a compact robot was then designed for manipulating a needle or other slender surgical instrument in the confined space. Its distinctive characteristic is the decoupled motion capability correlated to the positioning and orientation steps of the percutaneous intervention. This approach allowed each step of the intervention to be performed using a separate mechanism of the robot. One major advantage of this kinematic approach was patient safety.

To assess right ventricular free wall longitudinal myocardium deformation and examine the changes with normal age by speckle tracking imaging (STI), myocardial systolic peak strain (epsilon), systolic peak strain rate (SRs), early diastolic peak strain rate (SRe), late diastolic peak strain rate (SRa), the ratio of SRe/SRa were measured in the basal, middle and apical segments of right ventricular free wall in 75 healthy volunteers (age range: 21-71 y) by STI from the apical 4-chamber view. RV longitudinal strain and strain rate were highest in the basal segment of the free wall. Older subjects had lower early diastolic strain rate (SRe) than younger subjects, but they had higher late diastolic strain rate (SRa). A negative correlation between age and the ratio of SRe/SRa was found in all RV free wall segments (r=-0.466 - -0.614, P<0.01). It is concluded that RV diastolic strain rate changes with age and STI can be used for the study of RV myocardial deformation.
