Objective To study the surgical treatment of left colon cancer complicated with acute abdo-men.Methods From January 2000 to Dcember 2008,the clinic data of 36 patients with left colon cancer complicated by acute abdomen were analyzed retrospectively.All cases have been chosen emergency opera-tion.One-stage colectomy and annstomosis were performed in 28 cases,Hartmann in 5 cases and palliative colostomy in 3 cases.Results Anastomic leakage was found in one case after operation,infection of inci-sion happended in 4 cases,infection of lung happened in 2 cases,the times of defecation rised in one case,one patient died.Conclusion More attention shoud be paid to left colon cancer complicated by acute abdo-men.According to the patients'status,different operative manners were chosen.One-stage operation should be chosen firstly to improve quality of life and avoid staged operation.

Objective To assay free amino acids (FAA) content of breast cancer tissue and mammary glandular tissue and discuss the therapeutic basis of unbalanced amino acids of breast cancer. Methods The selected samples were conserved and then cut into pieces, grinded, syruped and deproteinized. Then FAA were separated from the samples. The content of 17 kinds of free amino acids in breast cancer tissue and mammary glandular were assayed respectively. Results The concentration of FAA in breast cancer tissue was higher than that in mammary glandular tissue. Conclusions Free amino acids metabolism was greatly different in breast cancer and mammary glandular tissues. This offers a therapeutic basis for the treatment of unbalanced free amino acids in the case of breast cancer.
