RESUMO
Objective:To investigate the clinical efficacy of different enteral nutrition methods combined with swallowing rehabilitation training in the treatment of Alzheimer's disease complicated by dysphagia.Methods:A total of 120 patients with Alzheimer's disease and dysphagia who received treatment in the Department of Geriatric Medicine, the Second Hospital of Jinhua from October 2019 to March 2021 were included in this study. They were randomly and evenly divided into four groups: A, B, C, and D. Patients in groups A, B, C, and D were given nasogastric tube feeding, naso-intestinal tube feeding, nasogastric tube feeding + swallowing rehabilitation training, and naso-intestinal tube feeding + swallowing rehabilitation training, respectively. After 12 weeks of treatment, total response rate, nutritional status, and complications were compared between the four groups.Results:After 12 weeks of treatment, total response rate in group D was the highest (100.0%), which was significantly higher than that in the other three groups (group A: 13.3%; group B: 40.0%; group C: 73.3%; χ2 = 45.88, 25.71, 9.23, all P < 0.05). After treatment, the nutritional status [body mass index (BMI): (21.42 ± 1.85) kg/m 2, (23.17 ± 2.03) kg/m 2] and patient satisfaction (60.0%, 100.0%) in groups C and D were significantly superior to those in group A [BMI: (19.01 ± 1.72) kg/m 2; patient satisfaction: 10.0%) and group B [BMI: (19.86 ± 1.69) kg/m 2; patient satisfaction: 33.3%]. Group D had the best nutritional status ( t = 7.01, 5.14, 1.78, all P < 0.05) and the highest patient satisfaction ( χ2 = 49.09, 30.00, 15.00, all P < 0.001). Conclusion:Naso-intestinal tube feeding combined with swallowing rehabilitation training is the best treatment for Alzheimer's disease complicated by dysphagia among the studied enteral nutrition feeding methods and therefore deserves clinical promotion.
RESUMO
BACKGROUND:Screening of fare blood types has been successively implemented and completed in Europe, America and Japan, but there is a large gap in China. Previous studies have mainly focused on the southern Han populations, and little is reported on PCR-SSP systematic analysis of gene frequencies of rare blood groups in Xinjiang Uygur populations. OBJECTIVE:To investigate the gene frequency distribution of RBC MNS, Duffy, Kel, Dombrock, Diego, Kidd, Scianna, Colton and Lutheran blood groups from Xinjiang Uygur populations, thereby providing a strategic support for human population genetics and clinical blood deployment. METHODS:PCR-SSP method was used to make genotyping and statistical analysis in 158 Xinjiang Uygur persons from nine rare blood groups. RESULTS AND CONCLUSION: Gene frequencies of these nine rare blood groups were M=0.579 1, N=0.420 9, S=0.174 3, s=0.800 9, Fya=0.699 4, Fyb=0.300 6, K1=0.015 8, K2=0.984 2, Doa=0.234 2, Dob=0.765 8, Dia=0.047 4, Dib=0.952 6, JKa=0.541 2, JKb=0.452 6, Sc1=1.000, Sc2=0, Coa=0.994, Cob=0.005 9, Lua=0, Lub=1.000, Aua=0.810 2, Aub=0.189 9. Results from chi-square test showed that the observed value and expected value of genotypes were in line with the law of Hardy-Weinberg equilibrium (P > 0.05), and in the MNS blood group of Xinjiang Uygur population, it was rarely found that S-s- frequency was 0.025 3 in four cases and Jka-b- frequency was 0.006 3 in one case. This study demonstrates that the frequency distribution of MNS, Duffy, Dombrock and Diego blood groups in the Xinjiang Uygur population, with its own unique frequency distribution characteristics, is different from that in other ethnic populations; the gene distribution of Kel, Kidd and Colton blood groups shows either similarity or difference between the Xinjiang Uygur population and reported Tibet and Han populations; Scianna and Lutheran blood groups show a monomorphic distribution in the Xinjiang Uygur population, which is similar to that in the Tibet and Han populations. These findings provide the basic data for exploring the origin and evolution, ethnic hematology and construction of rare blood database of the Xinjiang Uygur population.
