Objective To investigate the correlation between clinical presentations and the findings of video fluoroscopic swallowing study (VFSS)in patients with post-stroke dysphagia. Methods A total of 56 consecutive patients with post-stroke dysphagia admitted to Wenzhou Hospital of Traditional Chinese Medicine Affiliated to Zhejiang Chinese Medical University from June 2012 to May 2014 were enrolled. 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.

Aim To explore the potential mechanism of ulinastatin’s antioxidant effect by examining the Nrf2 /HO-1 pathway.Methods OVA-induced asthma of mice was cured by intraperitoneal injection of ulinas-tatin (1 00 kU·kg -1 ·d -1 ).Control mice were given the same volume of PBS (pH 7.4).To investigate the effect of ulinastatin on airway hyperresponsiveness, levels of interleukin IL-4,IFN-γand OVA specific IgE in bronchoalveolar lavage fluid (BALF)were measured using enzyme-linked immunosorbent assays (ELISAs). The content of ROS from BALF of mice was tested in double hydrogen rhodamine (DHR)-1 23 method.The level of protein carbonyl and MDA from lung tissue of mice was detected with Protein carbonyl content assay kit and MDA kit.And antioxidative enzyme in mice BALF was tested by antioxidant enzyme kit.The levels of HO-1 in lung tissue from mice were detected by Western blot and Real-time PCR.Nuclear transfer and binding activity of Nrf2 were tested respectively by Western blot,IF and EMSA.Results Ulinastatin could alleviate the airway hyperresponsiveness,dis-tinctly reduce the content of IL-4,OVA specific IgE, ROS,protein carbonyl and MDA,but upraise the ex-pression of IFN-γand antioxidative enzyme such as SOD,GSH and TAOC. Moreover, the antioxidant effect of ulinastatin could be reversed by Znpp,which was the inhibitor of HO-1 .Ulinastatin could obviously induce the expression of HO-1 in protein level in a dose-and time-dependent manner.Ulinastatin could also induce the nuclear transfer of Nrf2 and increase the binding activity of Nrf2 as well as the expression of HO-1 in gene level;Conclusion Ulinastatin could induce the activation of Nrf2 /HO-1 pathway,which may contribute to the protective effects of ulinastatin a-gainst OVA-induced oxidative stress.

Purpose To investigate the corre1ation of the epiderma1 growth factor receptor( EGFR)gene mutation and amp1ification and protein expression with occurrence and deve1opment of non-sma11 ce11 1ung cancer( NSCLC),and to exp1ore the re1ationship be-tween the mutation and amp1ification of EGFR gene and other c1inica1 patho1ogica1 parameters. Methods qRT-PCR,FISH and immu-nohistochemistry were used to detect EGFR gene(exons 18,19,20 and 21)mutation,amp1ification and protein expression in paraf-fin-embedded tissues of NSCLC. Results EGFR gene(exons 18,19,20 and 21)mutation rate was 58. 18%(32/55)in NSCLC with qRT-PCR techno1ogy,in which the occurrence rate of exon 19 de1etions and exon 21 mutation of L858R was 87. 50%(28/32). EGFR gene mutation rate was significant1y different in gender,smoking history and patho1ogica1 type(P<0. 01),but no statistica1 sig-nificance in age,1ymph node metastasis and TNM staging(P>0. 05). EGFR gene amp1ification rate was 23. 64%(13/55)and its protein expression rate was 70. 91%(39/55). Both EGFR gene mutation and amp1ification was c1ose1y corre1ated(P<0. 05),but the two states of EGFR gene and its protein expression had no corre1ation(P>0. 05). Conclusion EGFR gene mutation with high pro-tein expression of NSCLC is common1y found in fema1e,no-smoking and adenocarinoma patients,who are main candidates of a tyrosine kinase inhibitor( TKI)screening. EGFR gene mutation and amp1ification is typica11y corre1ated,but their consequence is unknown, which needs to be further investigated. EGFR gene mutation and amp1ification is not consistent with protein expression,its under1ying machanism is to be determined.

Objective To explore the significance of peritubular capillary C4d deposition in histopathological changes, renal function and prognosis of the patients with antibody-mediated chronic rejection (AMCR). Methods Deposition of C4d in the kidney was examined by irnmunohistochemistry on routine paraffin-embedded sections using anti-C4d polyclonal antibody. Seventy-seven patients were divided into C4d+ group (n = 35) and C4d- group (n = 42). The relationship of C4d and renal function,histopathological changes and prognoses of allografts were analyzed. Results The number of patients with tubular atrophy and glomerular basement membrane proliferation in C4d+ group was significantly more than that in C4d group (P<0.05). Mean serum creatinine level was significantly higher in C4d+ group than in C4d- group 12 months after renal transplantation [(379.1 + 260.2)μmol/L vs (260.5 + 175.3) μmol/L, P<0.05]. According to Kaplan-Meier analysis, the one-year graft survival rate was lower in the C4d+ group (62.9% ) than in the C4d- group (83.3% ) (logrank P<0.05). Conclusion Patients with C4d deposition are associated with tubular atrophy and glomerular basement membrane proliferation. The serum creatinine level in C4d+ patients was significantly higher than in C4d- group at the 12th month after transplantation. More patients with C4d deposition lost their grafts during the study period.
