Motor imagery therapy is based on the theory of plasticity in the central nervous system. Movement with imagery improved reconstruction of damaged motor conduction pathway, and made restoration of central nervous system. Motor imagery adapts to recovery mode of stroke, and was proved to be effective on motor function when applied with physical therapy for stroke patients. This article would review its background, mechanisms, Methods and effects, etc.

Objective To evaluate the validity and responsiveness of the Chinese version of the miniBalance Evaluation Systems Test(mini-BESTest).Methods A total of 208 stroke patients were evaluated by 2 professionals using both mini-BESTest and Berg balance scale (BBS).All data were analyzed using Pearson correlation,t-test and descriptive statistical analysis.Results Significant correlation was observed between each entry of the mini-BESTest and its domain,with correlation coefficients ranging from 0.78 to 0.93 (P ＜ 0.05).The scores of whole assessment and the three related domains were significantly correlated between mini-BESTest and BBS results,the correlation coefficients ranging from 0.68 to 0.87 (P ＜ 0.05).After 2 weeks of treatment,there was significant improvement in each domain and in the total assessment score (P ＜ 0.05).No floor or ceiling effects were observed in the total mini-BESTest scores,but there was a slight ceiling effect in the anticipatory and sensory orientation domains,and a slight floor effect in the reactive postural control domain.Conclusion The mini-BESTest has good validity and responsiveness,and can be applied to evaluate patients after stroke.

Objective To evaluate the efficacy and safety of intrapleural fibrinolytic agents in the treatment of childhood empyema.Methods The data from China National Knowledge Infrastructure (CNKI),Chinese BioMedical (CBM),PubMed,VIP Database and Cochrane library were reviewed.Randomized control trials by using intrapleural fibrinolytic agents to treat childhood empyema were included.Two reviewers independently extracted the data from the eligible studies and evaluated the quality of the included studies.Meta-analysis was performed for the results of homogeneous studies using RevMan 5.2 software,while others analyzed descriptively.Results Five randomized control trials involving 248 children with empyema were included.Meta-analysis was not made in all of the indexes because of apparent heterogeneity and limited data.Two trials were compared which involved 98 patients receiving fibrinolytic agents or 9 g/L saline.The results suggested that fibrinolytic agents shortened the length of hospital stay and reduced complication(all P ＜ 0.05),but no significant differences were found between the 2 groups in the effective rate,duration of fever and pleural effusion amount(OR =3.61,95％ CI 0.84-15.49,P ＞ 0.05).Three trials involving 150 patients compared fibrinolytic agents and video-assisted thoracoscopic surgery (VATS).The data suggested that no significant differences were found between 2 groups in the effective rate (OR =0.70,95 ％ CI 0.30-0.61,P ＞ 0.05),but fibrinolytic agents cost less (P ＜ 0.05).The adverse drug reactions to intrapleural fibrinolytic agents were mild to moderate,and well tolerated.Conclusions The findings suggest that intrapleural fibrinolytic agents in the treatment of childhood empyema is safe and effective,especially in encapsulated effusion.Compared to 9 g/L saline,it can shorten the length of hospital stay and reduce complication.Compared with VATS,the curative effect is similar,while intrapleural fibrinolytic agents are economic.

In view of the weakness of the teachers' strength, students' lack of interest and the lack of unity of teaching materials in the foreign language teaching, Oral Medicine College of Chongqing Medical University carried out the reform to the professional foreign language courses in the postgraduate education period by strengthening the preparation of special teaching materials, reinforcing teaching staff construction, reforming teaching methods and creating a learning environment. The results of teaching assessment by students and peer-reviewers show that reform has achieved good results, and aiming at the problems in the teaching practice we also put forward such improvement measures as strengthening the student-centered teaching method, promoting new teaching methods and optimizing curriculum assessment programs.

Objective To investigate the efficacy of BrainHQ visual training in rehabilitating memory function among stroke survivors.Methods Sixty stroke patients with memory disorders were recruited from the rehabilitation center of Tangshan Workers' Hospital.They were randomly assigned to a control group or an intervention group,each of 30.Both groups accepted conventional rehabilitation,while the intervention group was additionally given BrainHQ visual training five times a week for 30 minutes,lasting four weeks.Before and after the treatment,both groups completed the Rivermead behavioral memory test.Results After the 4 weeks of treatment,the average scores in recalling full names,recalling hidden items,recalling appointments,recognizing pictures,recognizing faces,recalling a story immediately,delayed story recall,recalling a route promptly,delayed route recall and the average total score in both groups were all significantly higher than before the treatment.The treatment group scored significantly better than the control group except in recalling hidden items,and recognizing faces and pictures.Conclusion BrainHQ visual training can improve the memory of stroke survivors.

Objective To investigate the changes in serum cortisol and adrenocorticotrophic hormone(ACTH) levels in children with steroid-sensitive nephritic syndrome (SSNS) and the clinical significance of intervention.Methods According to whether a child with SSNS would relapse,48 children with SSNS were divided into non-recurrence group(n =19) and recurrence group(n =29),at the same time 14 age-matched healthy children were enrolled as the healthy control group.Serum cortisol and ACTH were measured in patients with SSNS by using electrochemiluminesence methods.In recurrence group,methylpredisolone or methylprednisolone combined with ACTH injection therapy was used on 15 patients with their serum cortisol and ACTH below normal.Results Before standard glucocorticoid treatment,the serum levels of cortisol and ACTH had no difference among 3 groups (all P ＞ 0.05).By the end of remission phase,the serum levels of cortisol and ACTH in recurrence group were statistically lower than those of the non-recurrence group[(113.03 ± 80.02) μg/L vs (251.54 ± 185.05) μg/L,t =-2.925,P ＜ 0.05 ; (12.81 ± 10.14) ng/L vs (23.53 ± 12.05) ng/L,t =-0.885,P ＜ 0.05].Eight to 12 weeks after being adjusted,the serum level of cortisol and the average monthly time of recurrent were both significantly improved in 15 abnormal children in recurrence group [(168.90 ± 133.43) μg/L vs (73.62 ± 58.04) μg/L,t =3.016,P ＜ 0.05 ; (0.09 ± 0.08) times vs (0.35 ± 0.11) times,t =-7.560,P ＜0.05],but as to the serum level of ACTH,there was no significant difference in abnormal children in recurrence group [(14.05 ± 10.99) ng/L vs (8.72 ± 4.11) ng/L,t =1.991,P ＞ 0.05].Conclusions The concentrations of serum cortisol and ACTH can reveal the risk of recurrence for children with SSNS to some extent,and effective intervention can reduce the recurrence rate and shorten the course of disease.

(DBI) in rats by observation on the changes of Homer 1a expression and apoptotic nerve cells . Methods Spraque-Dawlley(SD) rats were randomly ( random number ) divided into control group and severe DBI group .DBI rat model was established according to the de-scription of Marmarou′s diffused brain injury .No injury was done on control group .The changes of neuron pathology were observed by light microscopy and electron microscope .The expression of Homer1a was observed by immunohistochemistry and western blot .The quan-tity of apoptotic cells was measured by terminal deoxynucleotidyl transfernase medicated nick end labeling ( TUNEL) method. Results The death rate of rats in severe DBI group was 49.3%.Compared with the control group , the ultrastructures in hippocampal neurons in-cluding organelle , axonal and capillary were damaged seriously after injury , the survival rate of nerve cells decreased significantly at 1 h after injury ([99.4 ±0.6]%vs [94.4 ±5.6]%, P<0.05), and peaked at 72 h ([99.2 ±0.8]%vs [54.7 ±33.8]%, P<0 .05) in DBI group.The expression of Homer1a protein increased significantly at 1 h after injury(0 .136 ±0.024 )and peaked at6 h(0.178 ± 0.028) and maintained to 24 h (0.176 ±0.027), while decreased at 48 h (0.145 ±0.02)and 72 h (0.117 ±0.012) in DBI group;the expression of Homer 1a was obviously higher at each time point in DBI group than that in control group (P <0.05).The apoptoticindex of TUNEL positive cells increased at 6 h and demonstrated significant difference at 72h in comparison to control group ([41.78 ±3 .96]%vs [1.92 ±0.22]%, P<0.05).The correlation analysis indicated that Homer1a expression from 1~24 h and 24 h~72 h was related to the survival rate of nerve cells ( r=-0.726, P<0.05; r=0.842, P<0.05) and the quantity of TUNE positive cells(r=0.738, P<0.0;5 r=-0.898, P<0.05). Conclusion The dynamic expression of Homer1a in hippocampus after severe DBI can reflect nerve cell loss.
