In this study,we report an unusual homing behavior of the Sichuan Partridge(Arborophila rufipectus)at the Laojunshan National Nature Reserve,Sichuan Province,*** Sichuan Partridges led the chicks back to the nests where they hatched in the evening and roosted there over *** behavior lasted 6.7±4.3 nights(range=1–15;n=13)after the chicks *** this stage,the hens became very vigilant to predators and human *** disturbed,they often abandoned the nests immediately and no longer returned *** ambient temperature at night during the early brooding period of Sichuan Partridge at our study site was^12.4°*** findings suggest that hen Sichuan Partridges may make trade-offs between nest predation risks versus the thermoregulatory needs of their young.

Background Heart failure due to ischemic heart disease is still a major health problem. Myocardium regeneration emerges as a novel therapeutic method for treating myocardial infarction （MI）. However, it is affected by many factors. The present study was aimed to investigate the effect of chemokine stromal cell-derived factor 1 （SDF-1）/CXCL12 on mesenchymal stem cells （MSCs） homing to injured myocardium in a rat myocardial infarction model. Methods A rat myocardial infarction model was established by permanent left anterior descending branch ligation. Mesenchymal stem cells from donor rats were cultured in IMDM and labeled with bromodeoxyuridine. The rats were divided into two groups. SDF-1 expression was measured by in situ hybridization and immunohistochemistry in the sham operated or infarcted hearts at 1, 2, 4, 7, 14 and 28 days post operation in the SDF-1 detection group. The rats in the intervention groups were injected with SDF-1, anti-SDF-1 antibody or saline 4 days after myocardial infarction. Then, a total of 5×10^6 cells in 2.5 ml of phosphate-buffered saline were injected through the tail vein. The number of the labeled MSCs in the infarcted hearts was counted on the 3rd day post injection. Cardiac function and blood vessel density were assessed on the 28th day post injection. Results Self-generating SDF-1 expression was increased at the first day post MI, peaked at the 7th day and decreased thereafter while it remained unchanged in sham operated hearts. The MSCs enrichment in the host hearts were more abundant in the MI groups than in the non-MI group （P=0.000）; the MSCs enrichment in the host hearts were more abundant in the SDF-1 injected group than in the anti-SDF-1 antibody and saline injected groups （P = 0.000）. Cardiac function was improved more in the SDF-1 injected group than in the anti-SDF-1 antibody and saline injected groups （P = 0.000）. Neovascularization in the SDF-1 injected group increased significantly compared to the other groups （P= 0.
