Objective To investigate the clinical value of radiotherapy combing with super selective esophageal intra-arterial infusion chemotherapy in advanced esophageal carcinoma. Methods 38 cases with medial or late stage of esophageal carcinoma wererandomly divided into two groups,the one group was treated with radiotherapy as the sole measure of treatment,while the other group was treated with radiotherapy combing with super selective esophageal intra-arterial infusion chemotherapy. All the patients were followed up within 3 to 24 months. Results In the most cases,the clinical symptoms and X-ray findings were improved obviously after treatment. But the rate of grade Ⅰof radiography was different obviously between two groups after different treatments.Conclusion Radiotherapy combing with interventional chemotherapy can increase drug concentration locally and therefore, has a better drug effect. On the other hand, it candecrease toxic reaction and can also decrease tumor volume effectively. So it can be a effective stratagem to those cases of locally advancedesophageal carcinoma which have poor reaction or severe radiotherapy reaction to merely radiotherapy.

Objective To investigate the expression and significance of KAI1/CD82 and E-Cadherin in human squamous cervical carcinoma.Methods The expressions of KAI1/CD82 and E-Cadherin were examined respectively by immunohistochemical S-P method in 10 cases of normal cervical tissue,15 cases of atypical hyperplasia of cervical epithelia and 64 cases of squamous cervical carcinoma.We analyzed statistically the correlation between the immunohistochemical results and the clinicopathological features.Results From normal cervical tissue,Cervical intraepithelial neoplasis(CIN) to cervical cancer,the positive expression rates of KAI1/CD82 and E-Cadherin were gradually decreased.Through statistic test,the positive expression rates of both invasive squamous carcinoma of the cervix were significantly lower in normal cervical tissue and CIN(P0.05).Of all the samples,direct correlation was showed in the expressions of KAI1/CD82 and E-Cadherin.Furthermore,the low-expression of both revealed significant correlation with lymphonode metastasis in human squamous cervical carcinoma.Conclusion KAI1/CD82 and(E-Cadherin) interactions may depress lymphonode metastasis in cervical carcinoma.Logistic analysis reveals that(E-Cadherin) gene,specific and interactions of several genes may be more significant during tumor metastasis.

BACKGROUND: Continuous oxygen inhalation of high concentration may improve antioxidase and simultaneously injure the lung in rats.OBJECTIVE: To observe the effect of intermittent high concentration oxygen on antioxidase activity and pulmonary tissue in rats.DESIGN: Complete randomized control experiment.SETTING: Department of Geriatric Cardiology and Department of Biochemistry, General Hospital of Chinese PLA. MATERIALS: The experiment was performed in Department of Hyperbaric Oxygen of Navy General Hospital and Department of Biochemistry of General Hospital of Chinese PLA from January 2002 to May 2002, in which, 10 healthy Wister rats were employed, mass weighted varied from 200 to 250 g, of either sex and randomized into two groups, 5 rats in each.METHODS: In the control, the rats were bred in the room environment for 7 days. In hyperoxic preconditioning (HP) group, the rats were placed in hyperbaric oxygen chamber and inhaled oxygen of 80％ to 85％ (101. 325 kPa) everyday for 6 hours, continuously for 7 days. At the end of experiment, the lung was collected to measure lung wet mass. 0.4 g pulmonary tissue was collected to prepare homogenate in freezing bath and its upper clear solution was collected to determine the activities of superoxide dismutase (SOD), glutathione peroxidase (GTTP) and catalase with chemiluminescence method successively. Pulmonary tissue was fixed with 30 g/L glutaradldehyde and prepared into sections to be observed the microstructure of lung under electron microscope.MAIN OUTCOME MEASURES: ① Comparison of lung wet mass and activities of SOD, glutathione peroxidase and catalase in pulmonary tissue in two groups. ② Alternation on microstructure of pulmonary tissue.RESULTS: Ten rats were all entered result analysis. ① Activities of SOD,GTTP and catalase in pulmonary tissue: Those in HP group were all higher remarkably than the control [(185.10±1.92) ％/g, (90.50±4.17) nkat/g,(4.38±0.18) k/g; (95.15±1.43) ％/g, (20.17±2.17) nkat/g, (1.10±0.19) K/g,t= -84.016, -33.488, -28.023, P ＜ 0.01]. ② Lung wet mass: That in HP group was near to the control [(1.32±0.07), (1.30±0.03) g, P ＞ 0.05], explaining that the fluid in the lung of HP group was not increased. ③ Microstructure of pulmonary tissue: In HP group, the basement membrane of pulmonary tissue was integrative and thickness was even, vascular endothelial cell was integrative and Ⅰ-type epithelial cell was not destroyed.CONCLUSION: Intermittent high concentration oxygen improves antioxidase activity in the lung of rat and does not injure the lung obviously.

This paper reports the technique to develop a disposable screen-printing base carbon electrode for the utilization in the study of enzyme electrode. The silk fibroin was applied to immobilize the mushroom extracted protein, which contained abundant polyphenol oxidase, on the surface of base electrode when it was chemically moldified by ferrocene. The voltammetric current of this enzyme electrode responded to the concentration of substrate such as catechol or dopamine. The linear range is from 2.0× 10-8 mol/L to 2.0× 10-2 mol/L, it reaches to a 95%steady value of current within less than 30 seconds, and the RSD equals to 2.7%. The service life of this enzyme electrode is at least 10 days and it will be preserved for a longer period at a humid and cool condition. All of these performances of the enzyme electrode make clear that its commercial development would be very possible.

Objective To investigate the long-term clinical outcomes in patients with anterior wall acute myocardial infarction ( AW-AMI) and non AW-AMI ( NAW-AMI) referred to primary percutaneous coronary intervention (P-PCI). Methods 287 patients with AMI who consecutively underwent primary PCI were divided into AW-AMI group (142 cases) and NAW-AMI group (145 cases) according to different location of myocardial infarction. The baseline characteristics and coronary artery lesions of patients were analysed. The primary end points were in-hospital mortality and the major cardiovascular events (MACE) during a mean 17.3?9.8 month follow-up including the occurrences of non-fatal myocardial infarction, non-fatal congestive heart failure, revascularization of target vessels and overall cardiac-related death. Results The peak value of CK and CK-MB were significantly higher (3 533?2 888) U/L vs (2 322 ? 1 638)U/L, (158 ? 197) U/L vs (95 ? 64) U/L, all P

Objective To investigate the expression level of cyclooxygenase-2 (COX-2) and its effects on cell proliferation activity and apoptosis in colorectal carcinoma. Methods The expression of COX-2, proliferating cell nuclear antigen (PCNA) and apoptosis in 60 cases of colorectal carcinoma, 20 cases of colorectal adenoma and 20 cases of normal mucous were studied by the immunohistochemical and TUNEL methods, the apoptosis index(AI)and proliferation index(PI) were defined respectively. Results The positive expression rate of COX-2 in colorectal carcinoma was significantly higher than that in the other groups. Overexpression of COX-2 in colorectal carcinoma was related to its lymph node metastasis and the size of tumor and clinical stages. In the group with COX-2 positive expression, PI was higher than that in the group with COX-2 negative expression; whereas AI was higher in the latter group than in the former group. Conclusions The expression level of COX-2 may have a close correlation with cell proliferation and apoptosis, they may participate in oncogenesis and progression of colorectal carcinoma.
