Objective To investigate the feasibility, safety and short-term efficacy of endoscopic implantation of 5-FU Slow-release Particles for advanced gastroenteric tumor. Methods During the endoscopy procedure,slow-releasing 5-FU agents were implanted densely into the tumors and infiltrated area. Forty-five to sixty pieces of agents ( each piece equivalent to 1.67 mg 5-FU)were injected, which containing an average dose of 100 mg 5-FU. Results A total of 13 advanced gastric cancer patients were enrolled into this study. Significant effects were observed in 3 patients and good effects in 8 patients, but 2 cases with no effects. The total effective rate was 84.62%. The endoscopy examination showed that the size of tumors reduced in various degree at 1 - 2months after the implantation. No hemorrhage or perforation was observed. Parameters of hepatorenal function and routine blood test were stable after implantation. Conclusion Endoscopic implantation of 5-FU Slow-release Particles can relieve the symptoms of patients and limit tumor growth in advanced gastroenteric tumor with no marrow and hepatorenal functional impair.

Objective To assess the usefulness of combined dual-energy CT pulmonary angiography (DE-CTPA) and indirect CT venography (CTV) in the diagnosis of venous thromboembolism (VTE).Methods Forty-nine patients with leg swelling suspected of pulmonary embolism (PE) underwent both DE-CTPA combined with CTV and lower extremity venous ultrasound (US) in 1-2 days prior to CT.Image quality of CTPA and dual energy lung perfusion image (DEPI) was rated using a 5-point scale and the coherence between CTPA and DEPI was analyzed by Kappa statistics.The ability of CTV and US in the diagnosis of deep venous thrombosis (DVT) was compared by Chi-square test.Results Twenty-nine of 49 patients were identified with PE by DE-CTPA,including 28 patients identified by CTPA and one more by DEPI,and 21 patients were found to have both PE and DVT.Both DE-CTPA and DEPI had positive findings for pulmonary embolism in 19 patients and both had negative findings in 18 patients.There was a moderate agreement between DEPI and DE-CTPA in the assessment of PE (Kappa value =0.7534).Thirty-eight patients with DVT were identified by US,while 35 patients were identified by CTV.Among the 35 patients with DVT identified by CTV,pelvic veins were involved in 25 patients,while the inferior vena cava was involved in 3 patients.There was no significant difference between CTV and US in the diagnosis of DVT(P =0.625).The detection rate of VTE with DE-CTPA combining CTV was 30.6％ higher than that with CTPA alone.Conclusions The combined DE-CTPA and CTV achievesone-stop examination.It not only provides evaluation of PE and DVT and increases detection of VTE,but also depicts perfusion defect of pulmonary parenchyma that corresponds to PE.

Objective To observe the anti‐metastatic effect and mechanism of baicalin on the growth of HeLa cells was measured by MTT assay ,and cell migration baicalin on human cervical cancer HeLa cells .Methods The effects of baicalin on the proliferation and invasion of HeLa cells were analyzed by MTT method and Transwell assay .Moreover ,Real‐time PCR was used for investigating the expressions of MMP‐2 and MMP‐9 at the RNA level .Western blot was used for investigating the expressions of MMP‐2 ,MMP‐9 ,P38 and p‐P38 at the protein level .Results Baicalin could significantly inhibit the proliferation of HeLa cells in the dose‐dependent manner at the concentration above 60 μg/mL . Anti‐metastatic signaling induced by baicalin was characterized by down‐regulating the RNA and protein expressions of MMP‐2 and MMP‐9 ,and down‐regulating the phosphorylation level of P38 . Pre‐treatment of P38 signal pathway inhibitor could enhance the inhibitory effect of baicalin on the expressions of MMP‐2 and MMP‐9 .Conclusion These results indicate that baicalin‐induced anti‐metastatic effect involves the inhibition of MMP‐2 and MMP‐9 in HeLa cells through P38 signal pathway .

Thiopurine S-methyltransferase (TPMT) is an important and key cytoplasmic enzyme in the metabolism of thiopurine drugs,whose activity can directly determine the amount of thiopurine drugs metabolized to cytotoxic 6-thioguanine nucleotides and consequently influence clinical efficacy and adverse drug reactions of thiopurine drugs.In order to deepen knowledge and role of genetic polymorphism of tpmt in the individualized thiopurine drug treatment,this present review mainly covered the following three frequently concerned aspects,including i) whether or not to determine the activity of TPMT priot to treatment of thiopurine drugs;ii) to genotype or to phenotype;iii) how to choose genotype methods.

Objective To evaluate whether Ly294002,suppressing phosphatidylinositol 3 kinase (PI3K)/AKT survival signaling pathway,can change the sensitivity of breast cancer cells to radiotherapy. Methods Breast cancer cultured MCF7 cells treated with:radiation alone;Ly294002;or the combination of radiation and Ly294002.The inhibition of PI3K/AKT by Ly294002 was confirmed by Western blot.Clo- nogenic assay was used quantitatively to measure the mitotic cell death,and caspase-3 assay was used to e- valuate apoptosis.Results 1.Ly29400 could partially inhibit phosphorylated AKT but not radiation,the combination of both could enhance the inhibition of phosphorylated AKT,2.Timing of exposing cells to Ly294002 had some impact on clonogenic survival by radiation,one hour pre-radiation and 10 days post-ra- diation exposing to Ly294002 could maximally sensitize the cells to irradiation,3.Ly29400 combined with radiation could synergistically enhance mitotic death and apoptosis of MCF7 cells,with SER of SF_4 and D_0, being equal to 1.25 and 1.42.Conclusions PI3K/AKT pathway may be a potential target for enhancing the response of breast cancer cells to radiotherapy.

Objective　To investigate the molecular regulation of G1 arrest of mouse thymocytes induced by ionizing radiation. Methods　Cell cycle was analyzed by flow cytometry (FCM) following staining of cells with proidium iodide. Fluorescent staining and flow cytometry analysis were employed for measurement of protein expression. Results　It was demonstrated that G1 phase of mouse thymocytes increased significantly at 12h after whole body irradiation (WBI) with the doses of 0.5, 1.0 and 2.0 Gy, and at 24h following 2.0Gy exposure, measured by FCM. In the time course experiment, it was found that G1 phase of thymocytes increased significantly at 4h, reached a peak level at 24h and came down toward 48h after WBI with 2.0Gy X-rays. The results also showed that after 2.0Gy exposure, the expression of proteins in mouse thymocytes increased significantlty from 1h to 8h for p53, for p21 from 4h to 48h, and for MDM2 at 4h and 8h, measured by FCM. But no change was found for GADD45 protein expression. Conclusion　These results suggest that G1 arrest could be induced by a single dose of 0.5 Gy, 1.0Gy or 2.0Gy, and its molecular control might be established through the p53-p21 pathway.
