ABSTRACT
Objective:To investigate the correlation between item d560 of the International Classification of Functioning, Disability and Health (ICF) and the swallowing function of convalescing stroke patients.Methods:A total of 140 convalescent stroke survivors were evaluated for dysphagia using the ICF-d560 and the modified Watian drinking water test. Linear regression was used to analyze the influence of clinical factors when choosing a swallowing function assessment scale. Spearman correlation was computed to explore the correlation between ICF item d560 and the modified Watian drinking water test.Results:According to the ICF-d560 results, 10% of the patients had a mild disorder, with another 37.1% moderate, 29.3% severe and 23.6% completely dysphagic. The corresponding percentages according to the improved Watian drinking water test were 44.3% mild, 31.4% moderate and 24.3% severe. The total correlation coefficient between the two sets of results was 0.86, which was related to the stroke type, age, gender and stroke risk factors. The correlation coefficient of the cerebral infarction group was significantly higher than the cerebral hemorrhage group′s coefficient, and that of the women was slightly higher than that of the men. The strength of the correlation increased with age. The correlation coefficient was 0.84 among both diabetics and hypertension sufferers.Conclusions:Results from the ICF-d560 and the modified Wada drinking water test correlate well, which can provide a screening tool for swallowing function based on the ICF theoretical framework.
ABSTRACT
Objective:To explore any correlation between ratings using item d550 of the International Classification of Functioning, Disability and Health (ICF-d550) and the nutritional status of patients with cerebrovascular disease.Methods:Nutritional assessments of 260 patients with cerebrovascular diseases hospitalized in a geriatric care hospital were carried out using the ICF-d550 and NRS2002 nutrition risk screening. The enter method was used to analyze the relationship between clinical factors and the scales. Spearman correlation coefficients quantified the correlation between ICF-d550 and NRS2002 results and the influence of clinical factors.Results:According to the ICF-d550 ratings the incidence of nutritional disorders was 85.00% while the NRS2002 reported 68.85%. The correlation coefficient between the two sets of results was 0.49, with the correlation coefficient of the males (0.53) slightly higher than that of the females (0.43). The correlation strengthened with age. The correlation coefficients of thin, normal and overweight persons were 0.61, 0.44 and 0.50 respectively.Conclusions:The ICF-d550 and NRS2002 can both be used to evaluate the nutritional risk of elderly patients with cerebrovascular disease, with good correlation.
ABSTRACT
Objective To prepare the human dual-specificity protein phosphatase18 (Dusp18) monoclonal antibodies (McAb) with high titer and specificity and identify its characterization, which is based on further studying Dusp18 function. Methods BALB/c mice were immunized with purified recombinant Dusp18 protein. Cell fusion was performed between mouse splenic cells and myeloma cells (SP2/0), and then the hybridoma cell lines secreting McAb against Dusp18 antigen were screened and cloned. The ascites were prepared and purified with Protein G affinity chromatography. The titer and subtypes of McAb against Dusp18 were identified and measured by ELISA and Western blotting analysis. Results Two hybridoma cell lines, F003 and F004, that stably secreted McAb against Dusp18 were successfully obtained, which belong to the subtypes of IgG1 and k light chain. The antibody titers in culture supematant were 1:5120 and1:10 240, and those in the ascites fluid were 1:25 600 and 1:51 200 respectively. Western blotting analysis and immunohistochemistry showed that the two antibodies can specifically bind with Dusp18 derived from human eucaryotic cells or tissue. Conclusion Two McAb against Dusp18 have been successfully prepared which can be used for further studying the biological properties of Dusp18 and reveal its relationship with tumorigenesis and development.
ABSTRACT
To develop simple, rapid, and efficacious diagnostic methods for malaria is one of the remaining key tasks for malaria control. Previously, we have created a phage-displayed antibody library against Plasmodium falciparum. Six clones of antibody with good reactivity to HRP-II in ELISA were isolated from the library after 3 rounds of enrichment. Soluble ScFvs were produced and the characteristics were determined. The results of Western blot showed that they could bind to HRP-II specifically and had a relative molecular mass(Mr) about 31 000. The work provided a solid fund for diagnostic kit development for malaria.
ABSTRACT
0.05). Of 98 cagE positive isolates, 14(14.3%) were cagA negative. Conclusion Most of the H. pylori isolates in Shanghai region may have intact cag PAI. cagE, could be taken as the marker for the presence of cag PAI. There is no correlation between the integrality of cag PAI and the clinical outcome of H. pylori of infection.
