The volume and function (the sensitivity and neurogenesis) of the olfactory bulb (OB) were reported to be altered among the MDD patients and rodent models of depression. In addition, the olfactory epithelium was newly reported to decrease its volume and function under chronic unpredictable mild stress (CUMS) treatment. However, the underlying molecular mechanism still remains unclear. Herein, we conducted the non-targeted metabolomics method based on gas chromatography-mass spectrometry (GC-MS) coupled with multivariate statistical analysis to characterize the differential metabolites in OB of CUMS rats. Our results showed that 19 metabolites were categorized into two perturbed pathways purine metabolism and lipid metabolism, which were regarded as the vital pathways concerned with dysfunction of OB. These findings indicated that the turbulence of metabolic pathways may be partly responsible for the dysfunction of OB in MDD.Endovascular therapy has been the first option for many vascular diseases. Due to the increasing development of endovascular devices and techniques in recent decades, endovascular procedures could be applied in treating those cases with complex anatomy. Two or three vascular access routes are required to establish through-and-through access in endovascular therapy for arterial occlusive disease and complex aortic aneurysm. Guidewire snaring with a snare kit is essential but sometimes time-consuming in the establishment of through-and-through access. To simplify the procedure, we design the magnetic kissing guidewire (MKG) with a magnetic tip that attracts each other to establish a guidewire route that meets the needs of clinical practice. We conducted the in vitro test to evaluate its magnetic force and the in vivo test to assess its performance in the arteries of twelve sh
