Objective To investigate the cellular fragments and particle image changes of inventory aleucocytic suspending RBC produced by the storage time extension ,RBC damage or hemolysis in order to provide the revelatory experimental basis for the transfusion safety .Methods The supernatant was prepared from different stored days (3 ,7 ,14 ,21 d) of stock aleukocytic suspen‐ding RBC .The particles in supernatant were observed and morphologically analyzed by using the microscopic static image analytic technology .Results There were a small amounts of visible particles in the sample supernatant preserved for 3 ,7 d and the parti‐cles′sizes are similar to cells′;the number of particles began to significantly increase from 14 d and the diameter became smaller . The particles filled the entire field until 21 d ,showing fragmentary status .Conclusion The cellular fragments and particles in the supernatants of stock aleukocytic suspending RBC with the storage period exceeding 14 d are significantly increased and have signif‐icant difference compared with those stored for less than 14 d .These exogenous fragments and particles may become antigens and induce the body immune response ,lead to transfusion adverse reactions .It is recommended that the patients should be transfused with stock aleukocytic suspending RBC within a storage period of 14 d .

Objective To evaluate total gastrectomy and regular lymph node dissection for the treatment of advanced cardiac cancer. Methods Three hundred and eighty-seven patients with advanced cardiac cancer underwent total gastrectomy D2+ procedure. The relationships between depth of invasion, lymph node metastasis,the number of metastastic lymph nodes dissected and postoperative survival rate were analyzed. Results The 3-year and 5-year survival rates were 47.3% and 34.2% , respectively. Metastatic rate of N3 lymph node was 4. 8% and 15. 2% in advanced cardiac patients of PT3 and PT4, respectively. Survival rates significantly decreased along with the increase of lymph node metastasis. The 3-year and 5-year survival of patients who had less than 15 lymph nodes dissected was significantly poorer than those who had more than 15 lymph nodes dissected, respectively. The postoperative complication rate and mortality rate of the two groups were 14. 2% and 2. 52% , respectively. Conclution To improve the quality of life and survival rate, D2 + radical total gastrectomy should be performed for advanced cardiac cancer, and when indicated resection of spleen and/or body and tail of the pancreas should be performed.
