Diffusion tensor imaging of two unrelated Chinese men with hereditary spastic paraplegia associated with thin corpus callosum

Hereditary spastic paraplegia (HSP) associated with thin corpus callosum is a rare autosomal recessive neurodegenerative disorder characterized by an abnormally thin corpus callosum, normal motor development, slowly progressive spastic paraparesis and cognitive deterioration. To investigate and localize abnormalities in the brains of two Chinese patients with HSP-TCC, with mutations in the spatacsin gene. Diffusion tensor imaging (DTI) was used to determine the mean diffusion (MD) and fractional anisotropy (FA) in the brains of the patients in comparison to 20 healthy subjects. Voxel-based analysis (VBA) of both the diffusion and anisotropy values were performed using statistical parametric mapping (SPM). Significant changes with MD increase and FA reduction were found in the already known lesions including the corpus callosum, cerebellum and thalamus. In addition, changes were also found in regions that appear to be normal in conventional MRI, such as the brain stem, internal capsule, cingulum and subcortical white matter including superior longitudinal fascicle and inferior longitudinal fascicle. Neither increase in FA nor reduction in MD was detected in the brain. Our study provides clear in vivo MR imaging evidence of a more widespread brain involvement of HSP-TCC. MD is more sensitive than FA in detecting lesions in thalamus and subcortical white matter, suggesting that MD may be a better marker of the disease progression.

The Gender of Chinese Christianity: Evaluating a New Research Perspective

This paper will discuss how the gender perspective can be applied to the study of the Early Modern Jesuit China mission. I will show that the category of gender provides a promising research perspective on Sino-Western cultural exchange, for it brings to the forefront important aspects of social life in the “contact zone” of Chinese Christian communities. I will argue that through the intercultural contact initiated by the Jesuit China mission, gender roles started to shift slightly on both sides. On the one hand, the Jesuits adopted the Confucian ideal of the separation of the sexes (nannü zhi bie), building for example separate Churches for women, something unknown in Europe. On the other hand, Chinese Christians were urged to reconsider aspects of their traditional gender norms, when for instance some men left their concubines in order to become Christian. The paper will be divided in three parts. First, it will focus on the history of concepts and discuss what gender relations meant in the context of the Early Modern China mission. Then it will turn to the representation of female religiosity in Jesuit Annual Letters and show how the gender perspective can lead to a re-evaluation this source genre. Finally, it will reflect on how the gender perspective can give us fresh insights into well-known paradigms on Sino-Western relations, taking the accommodation paradigm as an example.
