Objective According to the changes of microcirculation in the pulmonary cancers, the treatment effect was evaluated after the vascular interventional therapy.Methods Angiography of 138 primary pulmonary carcinomas, and the feeding arteries were performed. Areas of mass blush were measured for 81 cases before and after therapy. The tumour blush was considered to be the imaging appearance of the microcirculation of the lung carcinoma. The angiographic images were collected by digital image system (DSA and movie). Results (1) The rate of the tumour blush appearance was 88.8% in this group. (2) The areas of the lung carcinoma blush in 81 cases before and after therapy were (941.4?73.2)mm 2 and (427.9? 93.8 )mm 2( P

Objective: To study the influence of gallic acid (GA) on the migration of human gastric carcinoma SGC-7901 cells, and to explore its mechanism.Methods: The human gastric carcinoma SGC-7901 cells were cultured and divided into control group and 3.125, 6.250, 12.500, 25.000, 50.000,100.000 mg·L-1 GA groups. The inhibitory rates of proliferation of SGC-7901 cells in various groups were examined by MTT assay;the migration abilities of SGC-7901 cells in various groups were measured with scratch assay;the expression levels of vascular of endothelial growth factor (VEGF) in various groups were detected by immunocytochemistry.Results: Compared with control group, the inhibitory rates of proliferation of SGC-7901 cells in different doses of GA groups were significantly increased in a dose-dependent manner(F=59.451,P<0.01).Compared with control group, the wound healing rates in different doses of GA groups were significantly decreased (P<0.01).Compared with control group, the expression levels of VEGF protein in 12.500 and 25.000 mg· L-1 GA groups were decreased (P<0.05).Conclusion: GA could inhibit the proliferation and migration of SGC-7901 cells through down-regulating the expression levels of VEGF protein.

Glycyrrhizae Radix et Rhizoma is one of the commonly used Chinese materia medica in clinic. It has the effects of tonifying spleen and replenishing qi, clearing heat and removing toxin, dispelling phlegm, relieving cough, relieving pain, and reconciling various drugs. Its main active ingredients are saponins, flavonoids and polysaccharides. Among them, glycyrrhizic acid and glycyrrhetinic acid not only have inhibitory effects on liver cancer, lung cancer, breast cancer and other cancers, but also can be combined with chemotherapeutic drugs to increase drug efficacy as well. At the same time, they can be developed as drug carrier for drug delivery to solve the problems of low water solubility, low bioavailability, high toxicity and side effects of drugs. It was found that their solubilization may be closely related to their amphiphilic structure, which is expected to further explore the role of their carrier characteristics in drug transmembrane transport. Based on the anti-tumor mechanisms of Glycyrrhizae Radix et Rhizoma, the applications of glycyrrhizic acid and glycyrrhetinic acid in drug delivery systems were systematically summarized in this paper, which could provide reference for the further study of glycyrrhizic acid and glycyrrhetinic acid as excipients of drug delivery systems.
