RESUMEN
tomography angiography ( CTA) and T12-S1 vertebral computed tomography three-dimensional reconstruction were selected .The operative win-dows of L1 ~L2 OLIF were observed:the vascular window ,bare window ,psoas major window ,ideal operative window and actual operative win-dow.The operative windows ’ percentage accounted for ideal operative window were calculated ,the actual operative window based on an actual operative window of <1 cm,≥1 cm were statistically analyzed ,and the positions of the left renal artery and renal vein in front of operative window of L1 ~L2 OLIF were observed.Results The actual operative window was <1 cm in 2 cases (3.3%) and ≥1 cm in 58 cases (96.7%).In 58 cases,the difference was significant(P=0.008) in gender and men were more than women.The vascular window,bare win-dow and psoas major window accounted for the ideal operative window by 45%,43%and 12%,respectively ,and the actual operative window accounted for the ideal operative window by 55%.The left renal artery and renal vein's walking planes were at between the middle 1/3 of L1 to up 1/3 of L2 .There were 31 cases (51.7%) of the left renal artery being behind the left renal vein .Conclusion The regional anatomy of the operative window of L1 ~L2 OLIF has its own peculiarities,and not all L1 ~L2 levels are suitable for OLIF.The left renal vessels’ walk-ing planes were in front of L 1 ~L2 .Before L1 ~L2 OLIF surgery,surgeons should analyze the imaging anatomimy through imaging .
RESUMEN
Objective To investigate the f un ction of the autotransplanted splenic tissue. Method s 120 Kunming mice were randomly divided into two groups: sham operation group and group of 50% autograft splenic tissue implantation in the om ental pouch after total splenectomy. Six months after, splenic transplants were removed, and C 3b and Fc receptor and the expression of protein on the macr ophages was assayed in the implanted splenic tissue. Results The expression of protein and the receptor on the mac rophage in transplants were similar with that in the normal group. Conclusion The function of the macrophages in t he implanted splenic tissue judged by the expression of protein and receptor is normal, the autotransplanted splenic tissue can fulfil the function of the norma l spleen.
