Objective To study the relationship between the diabetic autonomic neuropathy (DAN) and the cerebrovascular disease. Methods The heart rate variability (HRV) was measured in 77cases of type 2 diabetes 〔49 men, 28 women, age (63.1?11.4)years〕. Forty-one cases suffered from DAN (group A), 36 cases without DAN (group B) according to the results of HRV. All the cases received the examination with transcranial Doppler ultrasonography (TCD). Results Compared with group B, the abnormality detected with TCD was higher in group A, cerebrovascular compliance was commonly decreased and cerebrovascular stenosis was also extensively observed. Conclusion DAN seems to be one of the risk fcators in inducing cerebrovascular disease.

Sex reversal, representing extraordinary sexual plasticity during the life cycle, not only triggers reproduction in animals but also affects reproductive and endocrine system-related diseases and cancers in humans. Sex reversal has been broadly reported in animals; however, an integrated resource hub of sex reversal information is still lacking. Here, we constructed a comprehensive database named ASER (Animal Sex Reversal) by integrating sex reversal-related data of 18 species from teleostei to mammalia. We systematically collected 40,018 published papers and mined the sex reversal-associated genes (SRGs), including their regulatory networks, from 1611 core papers. We annotated homologous genes and computed conservation scores for whole genomes across the 18 species. Furthermore, we collected available RNA-seq datasets and investigated the expression dynamics of SRGs during sex reversal or sex determination processes. In addition, we manually annotated 550 in situ hybridization (ISH), fluorescence in situ hybridization (FISH), and im-munohistochemistry (IHC) images of SRGs from the literature and described their spatial expression in the gonads. Collectively, ASER provides a unique and integrated resource for researchers to query and reuse organized data to explore the mechanisms and applications of SRGs in animal breeding and human health. The ASER database is publicly available at http://aser.ihb.ac.cn/.
