Aim To investigate the function of fenofi-brate on PAN ( puromycin aminonucleoside )-induced podocyte injury. Methods SD female rats of 18-week-old were randomly assigned into 3 groups ( n =6 ) . Mice in PAN group and fenofibrate treated group received a single intravenous injection of PAN ( 65 mg ·kg-1 ) , while those in control group received equal volume of saline. Mice in fenofibrate treated group re-ceived 40 mg · kg-1 · d-1 of fenofibrate ( intragastric administration ) on day 1 after PAN injection , while those in PAN group and control group received equal volume of vehicle. 24 hours urine samples from all group were collected on day 0(1 day before PAN injec-tion), day 6, day 10. The 24 hours urine protein was detected by Bradford assay. All the rats were sacrificed 10 days after the induction of podocyte injury, and glo-merulus sample were collected. The expression of podocyte injury marker and transcription level in apop-tosis, podocyte cytoskeleton protein, slit diaphragm protein were evaluated by Western blot and real-time PCR. Results Compared with the control group, 10 days after injection of PAN, 24 hours urine protein was obviously increased, and the expression and transcrip-tion level of podocyte injury marker desmin, apoptosis, podocyte cytoskeleton protein, slit diaphragm protein were upregulated greatly, however, those were signifi-cantly lower in fenofibrate treated group as compared with those in PAN group. Conclusions PPAR-α ago-nist fenofibrate can ameliorate PAN-induced glomerulus podocyte injury, and the mechanism involved may be associated with inhibition of the mitochondria apopto-sis, TGF-β/Smad pathway and p38 pathway.

Objective To analyze the ecological environmental differences of hibernation hole and temporary hole of Himalayan marmot based on global positioning system (GPS),remote sensing (RS) and geographical information system (GIS) in Yushu City,Qinghai Province.Methods Hibernation holes and temporary holes were located based on GPS.Ecological environment factors related with Himalayan marmot,such as land surface temperature (LST),digital elevation model (DEM),normalized different vegetation index (NDVI),were extracted based on RS and GIS.The ecological environment differences between hibernation hole and temporary hole were explored based on epidemiological statistical method.Results Monthly LST (degree Kelvin,K) of hibernation hole was slightly higher than that of temporary hole in the same period.Yearly day LST of hibernation hole was 1.1 K higher than that of temporary hole in the same period.Yearly night LST of hibernation hole was 0.3 K higher than that of temporary hole in the same period.Monthly NDVI of temporary hole was slightly higher than that of hibernation hole in the same period.Yearly NDVI of temporary hole was 0.001 higher than that of hibernation hole in the same period.DEM of temporary hole was about 40 m higher than that of hibernation hole.The top two ratios of soil type factors were both alpine meadow soil and dark felty soil for hibernation hole and temporary hole,which were 62.1％ and 29.3％,64.4％ and 25.6％.The top two ratios of land cover factors were both rainfed cropland and mosaic cropland for hibernation hole and temporary hole,which were 43.3％ and 25.8％,40.0％ and 26.2％.Conclusions Soil type factors and land cover factors for hibernation hole and temporary hole are similar.Lower DEM and higher LST are chose for hibernation hole,and better NDVI is chose for temporary hole,which is good for food intake.
