[Multi-index determination and optimization of liquirtin separated from polyamide resin].

To optimize the separation process of liquirtin from glycyrrhiz by static, dynamic adsorption and desorption experiments on polyamide resin, with liquirtin, isoliquiritin and glycyrrhizic acid as the study index. The optimum process conditions were that the pH of solution was regulated to be 7.0, the concentration of liquirtin was 1.

[Drug distribution in gastric cancer and adjacent tissues by preoperative intraperitoneal chemotherapy with Co-fluorouracil liposome].

Objective: To examine the distribution of fluorouracil in gastric cancer (CA), lymph node (LN), normal gastric mucosa (NG), peritoneum (PE), greater omentum (GO) and lesser omentum (LO) by preoperative intraperitoneal chemotherapy with Co-fluorouracil liposome (Co 5-Fu), and offer an experimental basis for clinic practice.

Methods: Ninety-six gastric cancer patients were divided into four groups: Co 5-Fu i.v.

[Expression of MUC1, CD44v6, nm23 in gastric carcinomas and regional lymph node tissues and their association with invasion, metastasis, and prognosis of the tumor].

Background & Objective: The invasion depth and lymph node metastasis result from the polygenes and their protein expression in gastric carcinoma. The key of the basic and clinical research of the gastric carcinoma is to find out the related molecular biology marker. This study was designed to investigate the relationship between the expression of MUC1, CD44v6, nm23 in gastric carcinomas and regional lymph node tissues and invasion, metastasis, and prognosis of the tumor.
