RESUMO
The neural stimulator is a core component of animal robots. While the control effect of animal robots is influenced by various factors, the performance of the neural stimulator plays a decisive role in regulating animal robots. In order to optimize animal robots, embedded neural stimulators had been developed using flexible printed circuit board technology. This innovation not only enabled the stimulator to generate parameter-adjustable biphasic current pulses through control signals, but also optimized its carrying mode, material, and size, overcoming the disadvantages of traditional backpack or head-inserted stimulators, which have poor concealment and are prone to infection. Static, in vitro, and in vivo performance tests of the stimulator demonstrated that it not only had precise pulse waveform output capability, but also was lightweight and small in size. It had excellent in vivo performance in both laboratory and outdoor environments. Our study has high practical significance for the application of animal robots.

Objective@#To investigate the correlation of single nucleotide polymorphisms (SNPs) in autophage-related 5 ( ATG5 ) gene promoter with acute myocardial infarction (AMI). @*Methods@#The SNPs of ATG5 gene promoter were detected by polymerase chain reaction (PCR) and Sanger sequencing. The typing and correlation of SNPs in 378 AMI patients and 374 healthy controls were analyzed by Chi-square test, Logistic regression analysis and haplotype analysis. @*Results@#Two SNPs of ATG5 gene promoter, rs506027 (OR=1.4, 95% CI \[0.6-3.0\], P=0.411) and rs510432 (OR=1.6, 95% CI \[0.7-3.4\], P=0.275), were found. They didn′t increase the susceptibility of AMI, and the haplotype associated with AMI was not found in the two SNPs. @*Conclusion@#The polymorphism of ATG5 gene promoter isn′t associated with the susceptibility of AMI.
