The Help is regarded as one of the representative works reflecting the life of black women in the 21st century in the United States.It takes the real events in history as its material,and adds fictional characters and plots to express the author’s thoughts on the social status of black women and the social problems.In terms of class,race,and gender,the author finds that the plight of black women is constantly repeating and they are still living at the bottom of society.From the perspectives of class oppression,racial discrimination,and gender discrimination,this paper explores the marginalized living conditions of black women in the United States and their spiritual salvation,thus analyzes the Black Feminism reflected in The Help. 展开更多

Dear Editor,β-Thalassemia is a common severe genetic disease caused by mutations in HBB and affects approximately 1.5% of the global population (Origa, 2017). In southern China, the carrier rate of β-thalassemia is as high as 6.43%, creating a high socio-economic burden (Xiong et al., 2010). In adult humans, there are three types of hemoglobin: HbA1 (~97%), HbA2 (~2%) and HbF (~1%). HbA1 (α2β2) is composed of two a-globin and two β-globi n sub units en coded by HBA and HBB, respectively;HbF (α2β2)is made up of two α-globin subunits and two β-globin sub units en coded by HBG. Mutations in the coding region or regulatory region of HBB are involved in β-thalassemia pathogenesis. Except for some rare dominant mutations, most HBB mutations are recessive (Origa, 2017). Depending on the mutation type, the β-globin level will either be reduced or completely depleted, resulting in α-globin accumulation and precipitation. These α-globin precipitates lead to red blood cell death, resulting in anemia and tissue damage, and even death in thalassemia major patients. Blood transfusions can help slow disease progression but lead to iron overload, ultimately resulting in iron toxicity. Bone marrow transfer is the only cure in the clinic and is available only to a small percentage of patients with human leukocyte antigervmatched donors. Recently, gene therapy and gene editing therapy have shown great promise in curing β-thalassemia (Glaser et al., 2015;Thompson et al., 2018). However, no appropriate animal models are available for evaluating the safety and efficacy of such advanced therapeutic strategies in vivo.β-thalassemia mice are the sole animal model available for research. However, substantial differences have been reported between the types and expressi on patter ns of human and mouse globins (McColl and Vadolas, 2016). Moreover, mice contain no fetal globin gene equivalent, and homozygous mutations of HBB in mouse for early models of β-thalassemia major or Cooley anemia are all embryonic lethal (Huo et al. 展开更多
