Parkinson’ s disease ( PD) is a neurodegenerative disorder primarily characterized by resting tremor, muscular rigidity, akinesia and postural reflex impairment.Behavioral tests of PD in animal models are essential for under-standing the pathogenesis of PD as well as for the development and testing of potential therapeutics .Here we mainly use the 6-hydroxydopamine (6-OHDA)-induced rat model, to introduce a review on the research progress in non-drug-induced be-havioral tests of motor function in PD rats.

AIM: To investigate the postoperative changes of binocular visual function in patients with congenital superior oblique palsy.METHODS: Eye position and binocular visual function were examined in 28 patients with congenital superior oblique palsy pre- and post-operatively. The results were statistically analyzed.RESULTS: The normal eye position rate after operation was 89.3%. There were 9 patients who gained simultaneous perception after operation, while 13 patients gained fusion as many as that gained stereoacuity. There was statistically significant difference between postoperative and preoperative eyes (P<0.05). Near stereoacuity was improved after operation. Patients who had better visual acuity and low strabismus degrees as well as fusion had a better recovery.CONCLUSION: The operation could improve the eye position and rebuild the binocular visual function of the congenital superior oblique palsy. The recovery of binocular visual function was related to visual acuity and strabismus degrees of the patients and whether they had fusion function.

Attention deficit hyperactivity disorder(ADHD)is a common childhood behavioral disorder,and it is characte-rized by the core symptoms of attention deficit,hyperactivity and impulsivity.In recent years,a variety of neuropsychological deficits related to ADHD have been confirmed,including intelligence,attention and inhibition,verbal and spatial working memory,set shift,planning and monitoring.Some important theories related to the metal mechanism of ADHD have been put forward,and the representatives include behavioral inhibition theory,cognitive-energetic model,dual pathway theory and state regulation theory.

AlM: To compare the results of 4 methods for measuring angle of exodeviation in the three types of intermittent exotropia, including when looking at indoor distance target of 6m, looking at indoor distance target of 30m, looking at outdoor far distance target, after 1h diagnostic occlusion test.
METHODS: Prospective case series study. Sixty-five patients with intermittent exotropia between June 2013 and June 2014 were enrolled in the Department of Ophthalmology, Affiliated Hospital to Qingdao University, included 37 males and 28 females with average age ( 12. 5 ± 6. 2 ) years. All the patients were measured when looking at indoor distance target of 6m, looking at indoor distance target of 30m, looking at outdoor far distance target, after 1h diagnostic occlusion test. lntermittent exotropia was divided into basic type, convergence insufficiency type and divergence excess type, which was based on the different result of between the distance and near measurements. The One-way test was applied to analyze the four methods of measuring angle of exodeviation in the three types of intermittent exotropia. LSD - t test was applied to compare the differences between each two methods in each type.
RESULTS: The distance exodeviations tested with looking at indoor distance target of 6m, looking at indoor distance target of 30m , looking at outdoor far distance target, after 1h diagnostic occlusion test were basic type (45. 4 ± 21. 0, 55. 0 ± 15. 0, 64. 68 ± 17. 7, 68. 75 ± 16. 6PD), convergence insufficiency type (33. 3 ± 14. 0, 44. 9 ± 12. 9, 43. 6±11. 8, 54. 6±11. 2PD), divergence excess type (55. 6± 17.4, 66.3±18.8, 76.9±16.4, 78.1±15.6PD). There were obviously differences between each two methods in each type ( basic type F = 9. 649, P = 0. 00; convergence insufficiency type F=6. 886, P=0. 001; divergence excess type F = 7. 989, P = 0. 00 ). Compared with looking at indoor distance target of 30m, looking at outdoor far distance target ( basic type P=0. 044, divergence excess type P = 0. 048 ) and after 1h diagnostic occlusion test (basic type P=0. 04, divergence excess type P=0. 027) had the statistical difference in the basic type and divergence excess type, and there was no obviously difference between looking at outdoor far distance target and after 1h diagnostic occlusion test ( basic type P=0. 353, divergence excess type P=0. 815). Compared with the other three measurements, 1h diagnostic occlusion test can elicit larger angle of deviation in the convergence insufficiency type.
CONCLUSlON: Both measurement with looking at outdoor far distance target and after 1h diagnostic occlusion test can elicit the larger angle of deviation in the basic type and divergence excess type; The measurement with after 1 hour diagnostic occlusion test can elicit the larger angle of deviation in the convergence insufficiency type.

Objective To study the related literature information of the core journal, Chinese Journal of Trauma, in 2003-2007 and evaluate its academic quality. Methods Analysis on literature information and quality evaluation were performed based on the A total of 1 708 related papers were selected from 60 issues of the journal from 2003 to 2007 to evaluate the quality of the journal in seven aspects. Re-suits (1) Average publication capacity index was 0.38 in five years. (2) The major sources of the au-thors were from medical universities or their affiliated hospitals and provincial or military medical units. (3) The major types of the papers were scientific researches, original articles and experience exchange (71.0%). (4) There were 326 grant-based projects, accounting for 35.9% of scientific researches and o-riginal articles. (5) There were average 10.2 quotations in each paper, including 72.2% of foreign docu-mentation, 27.8% Chinese documentation and 6.4% serf-citation. (6) Of all, 684 (75.3%) scientific researches and original articles applied statistical analysis. (7) Of all, 756 (87.4%) scientific researches and original articles were issued with English abstracts. Conclusion Chinese Journal of Trauma has the superiority in above seven aspects, which confirms its quality as a core journal.
