To investigate the mechanism of detrusor instability, using an apparatus to measure energy regulated tonicity and length of muscle strip in vitro , detrusor instability in bladder outlet obstruction (BOO) and spinal cord injuries (SCI) after pharmacological intervention was studied. The detrusor of both groups contracted under definite tension. Contraction of DI strips occurred under lower tension and under same tension the frequency of contraction was higher in DI detrusor than the normal one. There were no obvious changes when the detrusor strips were treated with M receptor antagonists, ATP or VIP. Muscarinic receptor agonist could increase the excitability of detrusor. The increase of detrusor excitability plays a major role in the occurrence of DI. The excitability is independent on neurogenic factors.

Since cardiopulmonary resuscitation(CPR)guidelines was constituted in 1974,it was adopted many times.The American Heart Association,in collaboration with the International Liaison Committee on Resuscitation(ILCOR),adopted new CPR science guidelines in January,2005.This article gives a short introduction of CPR,and showes the progress of several editions.

Objective To explore ICF-based measurement and statistical methods, and social support and service systems of intellectual disability. Methods ICF theories and approaches and literature review were applied. Results Based on the theories of function and disability in ICF, intellectual disability was characterized by the impairment of intellectual function and significant limitations in adaptive behavior, and onset before 18 years old. Based on the theories of intellectual disability in ICF, this study rebuilt the framework of intellectual disabili-ty, and modified the measure of intellectual disability by assessing the body function and measuring activities and participation to assess in-tellectual function and adaptive behavior, while analyzing the social support and service systems via environment factors. This study also dis-cussed related problems about the prevalence of intellectual disability. Conclusion New conceptual framework, measurement and statistical method of intellectual disability based on the theories and methods of ICF was discussed and the social support and service systems were in-tegrated into the environmental factor of intellectual disability.

Objective To establish an AGS cell line that stably expressing miR?126 and to study the effect of miR?126 on the proliferation and metastatic abilities of the AGS cell line in vitro. Methods AGS cells were infected by lentivirus with Lv?has?mir?126. After confirmation by RT?PCR ,CCK?8 and clone formation assays were used to evaluate the effect of miR?126 on AGS cell growth. Transwell migration and invasion assays were used to evaluate the effect of miR?126 on metastasis of AGS cells. Results We verified correct construction of recombinant AGS cells. RT?PCR confirmed mRNA levels of miR?126 existed significantly differences among the recombinant cell lines (P< 0.05). Proliferation assays and clone formation assays did not show a remarkable growth suppression in AGS?mir?126 cell line. However,transwell assay showed a notable acceleration in AGS?mir?126(P< 0.05). Conclusions We successfully constructed recombinant AGS cell line with stably high miR?126 expression level. MiR?126 could facilitate the metastasis of AGS cell in vitro.

Objective To explore the effect of ankle strategy stability limit training on balance and gait in recovering stroke patients with hemiplegia. Methods Forty recovering stroke patients were randomized into an intervention group and a control group.The patients in the intervention group were given ankle strategy stability limit training using visual feedback on the static long sets of a Smart Equitest Balance Master (SEBM) machine.Those in the control group practiced routine postural balance training using mirror visual feedback in parallel bars.Both groups of patients practiced balance and posture control for 30 minutes,once daily,6 days a week for two weeks. Both groups were also given routine therapy and other rehabilitation.The patients' balance function was evaluated using the Berg Balance Scale (BBS),and their gait was assessed using the walk across technique (WA). Results There was no significant difference between the two groups with regard to general information,BBS scores or WA results before treatment.After 2 weeks of treatment,BBS scores as well as the step length and pace in the WA improved significantly in both groups,but all improved significantly more in the intervention group.There was no significant difference in width of gait. Conclusion Ankle strategy stability limit training can enhance weight-bearing on stroke patients' affected foot as well as their balance and the symmetry of their steps.
