The study of container aims at centralized storage of the medical and survival dquipment on the medical helicopter,in order to make it convenient for unified management,thus enhance the rapid reaction ability of the medical helicopter.The structure and the arrangement inside thc container is designed according to the centre of gravity mechanics and requirement of the stored goods. It has a very resonable structure and a very clear arrangement.

Objective To investigate the role of Calcineurin binding protein 1(Cabin1)in renal tubular epithelial cells(RTECs)injury. Methods The male Sprague-Dawley rats were randomly divided into Sham-oper-ated and 5/6 nephrectomized group. Nephrectomized rats were further divided into two groups ,which were 4 and 8 weeks after operation,including 6 rats in each group. Rats were sacrificed at 4 or 8 weeks after nephrectomy,then control or remnant kidneys were harvested. 2μm sections of kidney tissues were collected and stained with Masson's trichrome and were graded for tubulointerstitial lesion score (TILS). RTECs mitochondrial morphology changes were detected by electron microscope. Western blot was applied to detect Cabin1 protein level in the renal tissue. Results At 8 weeks after the operation,plenty of RTECs fell off from the basement membrane,accompanied with interstitial fibrosis and the infiltration of inflammatory cells. Moreover ,TILS were significantly increased in rats at 8 weeks after operation while compared to sham-operated rats(7.16 ± 0.52 vs. 0.00 ± 0.00,P<0.05). RTECs mi-tochondria begun to swell at 4 weeks after 5/6 nephrectomy,while the disruption of cristae could be found in rats at 8 weeks. Cabin1 protein expression apparently increased in the remnant kidney. Cabin1 protein obviously increased in rats at 8 weeks after the surgery compared to sham-operated rats(0.97 ± 0.09 vs. 0.22 ± 0.07,P<0.05)and rats at 4 weeks after nephrectomy(0.97 ± 0.09 vs. 0.45 ± 0.03,P<0.05). Conclusions Cabin1 is overexpressed during RTECs injury in 5/6 nephrectomized rats. It can be a crucial factor regulating the damage of RTECs.

Objective To investigate the function and molecular mechanism of tacrolimus in podocyte injury and restoration.Methods Cultured podocytes were stimulated by Angiotensin Ⅱ (Ang Ⅱ) or Ang Ⅱ plus tacrolimus.Cells were collected at different time points (0 h,12 h and 24 h).The distribution of F-actin was observed after immunofluorescence staining,and the protein expression of nephrin and podocin were detected by Western Blot (WB).Results In normal control podocytes,F-actin was arranged in cytoplasm powerfully.Ang Ⅱ induced the disruption and discontinuity of F-actin.Tacrolimus inhibited the effect of Ang Ⅱ,stabilized the regular arrangement the F-actin.Compared to normal cells,the protein expression of nephrin in Ang Ⅱ group significantly decreased at 24 h after stimulation (0.76 ± 0.32 in AngⅡ group vs.1.18 ± 0.40 in normal group,P ＜ 0.05).And tacrolimus stabilized the expression of nephrin protein (1.00 ± 0.19 in treatment group vs.0.76 ± 0.32 in Ang Ⅱ group,P ＜ 0.05).Ang Ⅱ and tacrolimus did not affect the expression of podocin protein.Conclusion Tacrolimus inhibits podocyte injury induced by Ang Ⅱ,stabilizes the regular arrangement of cytoskeleton and protein expression of nephrin.
