Four different kinds of food were selectively used to complete clinical assessment of swallowing function and VFSS respectively. The SPSS 20. 0 statistical software was used to perform univariate and multivariate Logistic regression analyses for all observed indexes of the 2 methods. Results there were significant correlations in the point correspondence relation among the clinical manifestations and VFSS in food residue in the mouth and abnormal closure of lips in the oral phase (95%CI 1. 430-101. 468;P=0. 022);poor soft palate elevation and food residue in the mouth (95%CI 1. 476-102. 033;P=0. 020);graded swallowing and piecemeal deglutition with delayed oral transit (95% CI 2. 616 -182. 897;P = 0. 004);tongue movement disorders,poor soft palate elevation and tongue dyskinesia with poor bolus formation (95%CI 1. 468-50. 795,1. 220-13. 825;P=0. 017,0. 023);food leak from the corner of mouth,dysphagia,bolus falling to the epiglottis from the base of tongue or trachea (95%CI 1. 146-125. 459,1. 657-174. 400;P=0.038,0. 017). The weakened pharyngeal reflex with weak laryngeal elevation in the pharyngeal phase (95%CI 1. 150-92. 815;P =0. 037);dysphagia and delayed swallowing with prolonged triggering of swallowing reflex (95%CI 2. 123-37. 770,1. 233-114. 176;P=0. 003,0. 032);graded swallowing,hard swallowing, choking sensation,and poor laryngeal elevation with prolonged pharyngeal transit (95%CI 1. 619-223. 316,1. 061-31. 445,2. 834 -132. 707;P =0. 019,0. 042,and 0. 003);dysphagia and the opening of cricopharyngeal muscle insufficiency (95%CI 1. 037 -24. 115;P =0. 045);weak laryngeal elevation,foreign body sensation in the throat,and choking after swallowing with food retention or residual in vallecula or pyriform sinus (95%CI 1. 046 -13. 685,1. 116 -87. 741;P =0. 043, 0.040);and coughing during swallowing and eating choking or aspiration (95%CI 0. 010-0. 921,0. 037-0. 826;P=0. 042,0. 028). Conclusion Some clinical manifestations are closely correlated with the swallowing dysfunction revealed by VFSS. With the help of this law,it may more simply and safely determine the degree and type of dysphagia in patients,and provide guidance for patients with dysphagia after stroke who can not accept VFSS in the rehabilitation treatment.

Objective:To explore the relationship between spino-pelvic sagittal and coronal parameters in Lenke 1 group of adolescent idiopathic scoliosis (AIS).Methods:The subjects were retrospectively col-lected from 2005 to 2013.On the posteroanterior and lateral radiographs, apical vertebra ( AV) , Cobb an-gle of main thoracic curve (MT), pelvic incidence (PI), C7 translation ratio (C7TR) and other sagittal parameters were measured and recorded.Comparison and correlation studies were conducted between these parameters using specific softwares.Results: In the study, 51 subjects, including 18 males and 33 fe-males, were recruited, aged (14.9 ±2.0) years averagely.The apical vertebra ranged from T7 to T11,with mean MT being 49.6闭±16.7闭, and mean PI 44.7°±6.7°.Significant correlation existed between PI and PT, SS, LL, as well as between LL and SS, TK ( P <0.05) .Significant differences were found in TK, LL and SS among the different LM groups, but no difference in the other sagittal parameters.AV had no significant correlation with any sagittal parameter.MT was significantly correlated with TK, LL and SS, but its correlation with PI was not significant.Conclusion:Most of sagittal parameters were significantly corre-lated in Lenke 1 adolescent idiopathic scoliosis, forming a regulation chain of spine-pelvic sagittal balance on the basis of PI.Significant correlation exists between some sagittal and coronal parameters.

Objective To observe the effects of extracorporeal shock wave therapy (ESWT) on spasticity of biceps brachii after stroke. Methods 12 patients with spasticity of biceps brachii after stroke were divided into control group (n=6) and ESWT group (n=6). The ESWT group received a session of ESWT and the control group received placebo treatment. All patients were assessed before and immediately after treatment, including integrated electromyogram (iEMG) and co-contraction ratio during maximum isometric voluntary contraction (MIVC) of elbow extension with surface electromyography, the modified Ashworth Scale (MAS) and content of shoulder and elbow of Fugl-Meyer Assessment (FMA). Results The scores of MAS and FMA, the iEMG and the cocontraction ratio of biceps brachii improved in the ESWT group after the treatment (P<0.05), and improved more than those in the control group (P<0.05). Conclusion ESWT can immediately relieve the spasticity of biceps brachii, inhibit the cocontraction of biceps brachii during elbow extension and improve the motor function of upper limb in patients post stroke.

Objective:To study the antitumor effect and mechanism of cocultured CIK cells modified with IL-24 gene and autologous DCs on HL-60 cells in vitro.Methods:DCs and CIK cells were prepared routinely from human peripheral blood mononuclear cells ( PBMC).IL-24 gene was transferred into CIK cells via electroporation.The cells obtained were named CIK-IL24.RT-PCR and ELISA were used to evaluate expression of IL-24 gene in transfected CIK cells.The phenotypic changes of CIK cells were identified by flowcytometry analysis.The concentration of IFN-γ and TNF-α in supernatant of CIK was determined by ELISA.FCM was used to determine the cytotoxicity of cocultured CIK cells modified with IL-24 gene and autologous DCs against HL-60 cells.Results:Eukaryotic expressing plasmid pcDNA3.0-IL24 was transferred into CIK cells successfully via electroporation.The expressing rate of CD3~+、CD3~+CD56~+ cells had no significant change in CIK cells.However,the rate of CD4~+CD25~+ cells was significantly decreased compared with that of the control group.Expression of adhesion molecules CD54,CXCR4 were significantly increased on CD3+CD56+ cells.CIK-IL24 cells produced markedly higher levels of IFN-γ and TNF-α as compared with the CIK cells.By comparison with non-transfected CIK cells co-cultured with DCs,transfected CIK cells co-cultured with DCs had a significantly higher lytic activity against HL-60 cells.Conclusion:IL-24 gene modification can enhance the anti-tumoral immunity of CIK cells,the mechanism of which might be related to the increased secretion of IFN-γ,TNF-α,up-regulation of adhesion molecule expression,and reduction of the rate of CD4~+CD25~+ cells in CIK cells.
