BACKGROUND: From yiyiren oil is extracted kanglaite injection that has been extensively used against lung cancer for its function against cancer. It is revealed that kanglaite injection inhibits many strains of cancer cells including LA795 metastatic lung cancer. Genechip is used here for detection of metastasis reactive differentially expressed genes in mice that carry LA795 metastatic lung cancer.OBJECTIVE: To detect the metastasis reactive diferentially expressed genes with genechip technology in metastatic cancer carrying mice that treated with y iyiren oil injection(kanglaite injection).DESIGN: It was a controlled trial with mice as subjects.SETTING: Oncology Department of Xiyuan Hospital Affiliated to China Academy of Traditional Chinese Medicine.MATERIALS: The trial was conducted from February through August 2003. Forty mice were implanted with T739 strain lung adenocarcinoma cells and were randomly and averagely assigned into 2 groups.METHODS: mRNA probe was made from cancer sample of the mice. ScanArray 3000 scanner was used to scan the fluorescence signal in cDNA expression genechip that contained 4096 mouse genes in order to detect the differentially expressed genes.MAIN OUTCOME MEASURES: The differentially expressed genes in the two groups of mice.RESULTS: The mice genes expressed differentially between the kanglaite injection group and control group. After examination being repeated for 3 times, 27 genes presented different expression; 25 genes expression increased in both groups and 2 genes decreased. Among these differentially expressed genes, 12 genes were of the mouse muscle cDNA. It was also observed that 6 genes might be associated with the occurrence and development of tumor.CONCLUSION: Gene expression spectrum genechip is useful in effectively detect the relevent differentially expressed gene induced by kanglaite injection.

Objective To estimate the sensitivity of malignant cells from ascites of gastric cancer to anticancer agents by in vitro sensitivity test, and to study its value in individualized intraperitoneal chemotherapy. Methods Forty-seven cases of gastric cancers with malignant ascites were selected. The gastric cancer cells were isolated from the ascites of 19 patients with gastric cancers, and in vitro sensitivity tests to carboplatin, taxol, fluorouracil, cisplatin, adriamycin, hydroxycamptothecine, methotrexate, mitomycin and dacarbazine were performed by ATP bioluminescence assay. One of the most sensitive drugs was applied to intraperitoneal chemotherapy. The rates of the patients with complete remission of ascites and with disappearance of intraperitoneal cancer cells in the sensitivity test group were compared to those of 28 patients in control group who all were treated with intraperitoneal cisplatin. Results In sensitivity test group, the sensitive cases to carboplatin, taxol, fluorouracil, cisplatin, adriamycin, hydroxycamptothecine, and mitomycin were 7,6,6,6,5,5 and 5 respectively. No case was sensitive to methotrexate or dacarbazine. The rates of patients with complete remmission of ascites and the rates of patients with disappearance of intraperitoneal cancer cells in the sensitivity test group were significantly higher than those in cisplatin control group(68.4% vs. 32.1%, P

Objective To observe the blind area in routine gastric lavage and evaluate its significance. Methods Each of 10 healthy volunteers drank 60 ml water containing 185 MBq 99mTc. Images of mouth, esophagus and stomach of all subjects were collected from anterior position with gamma camera, and intraoral and intraesophageal radiocounts were monitored with " Region of Interesting" technique at 0, 0.5, 1,2,3 and 4 hours. Ratios of the counts at subsequent time points vs the count of 0 hour were calculated. For other 13 volunteers, 100 ml, 200 ml, 300 ml and 400 ml normal saline containing 25% compound meglucamine diatrizoate were drunk and injected into stomachs through stomach tube respectively. After that, X-ray chest films were taken at the dorsal and left lateral decubitus positions to observe the oral and e-sophageal developments. Results The images of mouths and esophagus of 10 subjects could be identified more than 4 hours after the administration of 99mTc. The ratios of oral counts and esophageal counts at 0. 5 ,1, 2, 3 and 4 hrs were 30. 7% , 10. 5% , 6. 3% , 4. 7% , 3. 7% , and 18. 6% , 4. 4% , 3. 5% , 3. 0% ,2. 7% respectively. The ratios of both oral and esophageal counts were 49. 3% , 14. 9% , 9. 8% , 7. 7% and 6.4%. When the liquid was drunk, full oral and esophageal developments could be identified. While the liquid was injected through the tube, no development was found. Conclusions Liquid drug may remain in mouth and esophagus for a long period of time after administration. Routine gastric lavage through nasogastric tube can not clean the oral and esophageal drug residues. There are oral and esophageal blind areas when routine gastric lavage is employed.
