[Effect of Astragalus mongholicus on renal gene expression profile in mice with diabetic nephropathy].

Objective: To study the effect of Astragalus mongholicus on renal gene expression profile in mice with diabetic nephropathy by cDNA microarray.

Method: The mice with diabetic nephropathy were fed A. mongholicus and normal saline respectively.

[Comparative study on the exfoliative cytology of intraoperative peritoneal lavage in patients with rectal cancer pre- and post-tumor resection].

Objective: To investigate the clinical value of sequential intraoperative peritoneal lavage in reducing the positive rate of peritoneal exfoliated tumor cells.

Methods: Six sequential intraoperative peritoneal lavages were performed in each of the 63 patients with rectal cancer, with three before resection and three post resection, which were then compared by using cytological smear examination.

Results: Exfoliated tumor cells were positive in the first three intraoperative peritoneal lavages of all the 63 patients before resection.
