Ocular ischemic syndrome(OIS) is a disease seen in cardiology,ophthalmology,neurology and neurosurgery,which is characteristic by brain and ocular symptoms caused by carotid artery obstruction or stenosis.The diagnosis of OIS may be difficult because of its variable presentations and its concealed onset.What is more,its pathogenesis is not completely clear,and therefore its treating efficacy is dissatisfactory so far.The current study on OIS is focused on experimental research.So establishment of suitable animal model is important.Recently years,the creating method of OIS model made a great progress.The selection of model animals,extablishing methods of models and comparison of various models were summarized.

Objective:To study the expression of IQ motif containing GTPase activating protein 1 (IQGAP1 )in oral squamous cell cancer(OSCC)tissue,and to explore the effects of IQGAP1 on cell proliferation and invasion as well as its underlying mechanism. Methods:Expression levels of IQGAP1 in tumor and adjacent normal tissues were examined by western blot and RT-PCR.OSCC cell line SCC-4 cells was transfected with the recombinant plasmid-pcDNA3.1 -IQGAP1 by lipofectamine,and then treated with an Akt in-hibitor.The phosphorylation of Akt,cell proliferation and invasion were detected by western blot,MTT assay and Transwell invasion as-say respectively.Results:Protein and mRNA expression levels of IQGAP1 were higher in cancer tissue than in adjacent normal tissue (P <0.05).Transfection of pcDNA3.1 -IQGAP1 increased IQGAP1 expression,enhanced the capability of cell proliferation and inva-sion (P <0.05),increased p Akt level in the cells.Preconditioning with an Akt inhibitor reduced p Akt level.Furthermore,silencing Akt pathway blocked the increase of cell proliferation and invasion induced by IQGAP1 overexpression(P <0.05).Conclusion:IQ-GAP1 overexprission can mediate the ability of proliferation and invasion of OSCC cells by regulating the activation of Akt pathway.

Objective To analyze the type of family function of children with cerebral palsy. Methods The data collected from 206 valid questionnaires were analyzed. Results The Total Function dimension was as the characteristic value in the family function. The result showed that children's family function could be divided into three types, namely, Problem Solving (M=26.5402), Effective Communication (M=23.4719) and Emotional Intervention (M=33.3750). Problem Solving (47.28%) and Effective Communication (48.37%) were the main types. Conclusion Family function of children with cerebral palsy can be mainly divided into Problem Solving and Effective Communica-tion, less of Emotional Intervention.

Objective To observe the effect of acupuncture on antagonistic muscles with spastic paralysis stroke. Methods A total of 84 patients with stroke spastic paralysis according to the inclusion criteria were randomly divided into treatment group (42 cases) and control group (42 cases). Both groups were given rehabilitation training. The treatment group combined the acupuncture on antagonistic muscles, while the control group combined the convertional acupuncture and acupoints. All patients were treated for 2 months. Modified Ashworth, clinic spasticity index(CSI), Fugl-Meyer motor function (FMA) and daily living ability (ADL-Barthel index ) were used for evaluation of the therapeutic effect. Results After the treatment, the CSI score of the ankle (10.70 ± 1.49 vs. 11.60 ± 1.17, t=-2.586) of the treatment group was significantly lower than the control group (P<0.05), while the Fugl-Meyer motor function score (67.40 ± 13.91 vs. 54.65 ± 8.41, t=4.200) and Barthel index score (69.15 ± 12.43 vs. 57.65 ± 8.35, t=4.475) of the treatment group were significantly higher than the control group (P<0.01). The ashworth scale of elbow, wrist, knee joint spasticity changed significantly in the treatment group when that index after treatment was compared with that before treatment (χ2 value 10.627, 10.261, 10. 200, respectively, P<0.05). Conclusion Acupuncture on antagonistic muscles could improve the spasticity, motor function and daily living ability of patients with spastic paralysis stroke.

BACKGROUND:At present,withthe aging trend of the world’s populationand social development,the proportion of hip fracture is on the rise, and the morbidity and mortality ratearehigh. Therefore, it is necessary to analyze the risk factors for death in old patients with hip fractures. OBJECTIVE:To review and systematicaly analyze the deathrisk factors for hip fracture al over the world. METHODS:The PubMed, Medline, EMBASE, the Cochrane library, China Knowledge Resource Integrated Database, VIP database resources were reviewed for mortality risk factors for hip fracture in the elderly. Meta analysis of mortality risk factors for hip fracture in the elderly was conducted by Stata11.0 software, and then the pooled odd ratio (ORs) and 95% confidence interval (95%CI) of each risk factor were calculated from the patient’s own factors and iatrogenic factors in order to analyze risk factors for hip fracture in the elderly. RESULTS AND CONCLUSION:(1) 47 literatures were searched and among them 27 literatures were included in our meta-analysis. (2) The results of meta-analysis showed that mortality risk factors for hip fracture in the elderly included male, older than 60 years of age, body mass index, high American Society of Anesthesiologists Score, delay time from fracture to surgery, poor daily living before fracture, type of fracture, pre-fracture lung disease, pre-fracture cardiovascular disease, and pre-fracture dementia. (3) Results indicated that high mortality of the elderly patients with hip fractures possibly resulted from combined actions of physiological condition, operative factors andpostoperative rehabilitation. Before treatment, fuly understanding the patient’s physical function and health status, fuly assessing the risk of surgery, and selecting the appropriate type of surgery can reduce complication rate and mortality and improve patients’ prognosis.
