ABSTRACT
Objective To explore the effect of Xingnao acupuncture combined with swallowing rehabilitation training on dysphagia after stroke .Methods 66 patients with dysphagia after stroke were selected as the research subjects ,and they were randomly divided into the observation group and the control group ,33 cases in each group .The control group was given rehabilitation training on the basis of conventional treatment ,while the observation group was given Xingnao acupuncture method on the basis of the control group .The therapeutic effect ,swallowing function and adverse reactions were observed before and after treatment in the two groups .Results After treatment,the treatment effect in the observation group was significantly better than that in the control group ,there was statistically significant difference between the two groups (Z=-4.123,P<0.05).The total effective rates of the two groups were 93.94％, 75.76％,respectively,there was no statistically significant difference between the two groups (χ2 =1.906,P>0.05). After treatment,the Watian drinking water test scores,standardized swallowing assessment (SSA) score,dysphagia score in the control group were (1.39 ±0.47) points,(23.02 ±5.24) points,(1.25 ±0.55) points,respectively, which in the observation group were (0.74 ±0.39) points,(18.26 ±3.71) points,(0.74 ±0.28) points,and the differences were statistically significant compared with before treatment ( the control group:t =21.453,10.644, 26.212,all P<0.05;the observation group:t=27.779,14.15,37.469,all P<0.05),which in the observation group were better than those in the control group ,the differences were statistically significant ( t=6.114,4.259,4.747,all P<0.05).There was no statistically significant difference in the incidence of adverse events between the two groups (P>0.05).Conclusion Xingnao acupuncture combined with swallowing rehabilitation training in the treatment of dysphagia after stroke can effectively improve the swallowing function ,improve the quality of life of patients ,and it is safe,reliable and worthy of promotion in clinical practice .
ABSTRACT
To understand epidemiological characteristics of Marek's disease virus (MDV) prevalent in china currently,3 Marek's disease (MD) strains were isolated and identified from white feather meat chickens vaccined with MDV CVI988 or 814 through necropsy,histopathological observation,virus isolation and IFA detection,named SDAU1501,SDAU1502 and SDAU1503,respectively.vIL8,pp38,MEQ gene of the three strains of MDV were amplified using PCR,and compared with reference strains.The homology between SDAU1501 and SDAU1502 and virulent strains was above 97％,suggesting some features of virulent strains;while meq gene of SDAU1503 lost P amino acid at the 194 th site as that in CVI988,But the distinctive 177 nucleotide insertion mutations was not existed,predicting that it may be a attenuated vaccine strain.New variations of MDV continued and different types of variants emerged,therefore,prevalence and genetic monitoring of MD should be proceeded;meanwhile,more attentions should be given to MDV vaccine development.
ABSTRACT
The genomic diversity of Avian leukosis virus subgroup J (ALV-J) was investigated in an experimentally infected chicken. ALV-J variants in tissues from four different organs of the same bird were re-isolated in DF-1 cells, and their gp85 gene was amplified and cloned. Ten clones from each organ were sequenced and compared with the original inoculum strain, NX0101. The minimum homology of each organ ranged from 96.7 to 97.6%, and the lowest homology between organs was only 94.9%, which was much lower than the 99.1% homology of inoculum NX0101, indicating high diversity of ALV-J, even within the same bird. The gp85 mutations from the left kidney, which contained tumors, and the right kidney, which was tumor-free, had higher non-synonymous to synonymous mutation ratios than those in the tumor-bearing liver and lungs. Additionally, the mutational sites of gp85 gene in the kidney were similar, and they differed from those in the liver and lung, implying that organ- or tissue-specific selective pressure had a greater influence on the evolution of ALV-J diversity. These results suggest that more ALV-J clones from different organs and tissues should be sequenced and compared to better understand viral evolution and molecular epidemiology in the field.
