RESUMO
Objective To observe the clinical efficacy of electroacupuncture in treating deglutition disorders after radiotherapy of nasopharyngeal carcinoma. Method Forty nasopharyngeal carcinoma patients with deglutition disorders after radiotherapy were randomized into a treatment group and a control group, 20 in each group. The control group was intervened by nourishing nerve, improving microcirculation, promoting nerve growth factor, and physical rehabilitation. Based on the treatment given to the control group, the treatment group was additionally intervened by electroacupuncture. Water drinking test was adopted to evaluate the deglutition function before and after intervention, and the clinical efficacy was compared. Result After intervention, there was no significant difference in comparing the deglutition function between the two groups (P>0.05). The total effective rate was 80.0%in the treatment group versus 50.0% in the control group, and the difference was statistically significant (P<0.05). Conclusion Electroacupuncture is an effective method in treating deglutition disorder after radiotherapy of nasopharyngeal carcinoma.
RESUMO
Whole mount in situ hybridization with BHC80 RNA probe showed that BHC80 was expressed in zebrafish central nervous system. Morpholino-modified antisense oligonucleotide was injected into zebrafish zygotes to knock down BHC80 expression. BHC80 knockdown resulted in striking decrease of erythrocytes and accumulation of erythrocytes at PBI. Further investigation of embryonic erythrocytes marker βe3 globin and hematopoiesis transcription factors gata1, c-myb and lmo2 by in situ hybridization showed that the erythroid progenitors marked with gata1 in BHC80 knockdown embryos were high proliferation and their differentiation were delayed, which led to decrease of erythrocytes and accumulation of erythrocytes at PBI. Both in situ hybridization and microangiography indicated that vasculature pattern of BHC80 knockdown embryos were almost normal.
