Chemoradiotherapy is an important part in the adjuvant regimen for locally advanced gastric cancer after radical resection. Adjuvant chemoradiotherapy has demonstrated a clear local control and survival advantage for locally advanced patients with less than D2 lymph node dissection. Thus, chemoradiotherapy is recommended as standard of care in the postoperative setting. However, the role of radiotherapy for patients with more extensive D2 lymph node dissections remains controversial. Three phase III random-ized clinical trials in Asia show that adjuvant chemoradiotherapy after D2 dissection is safe and feasible and may benefit certain groups of patients. The benefit of radiotherapy in the case of more extensive surgery still warrants well-designed, fully powered randomized controlled clinical trials for verification. More studies are needed to focus on the identification of patient subgroups that are at high risk for locoregional failure and may benefit from adjuvant chemoradiotherapy. Further optimization of target volume in the radiother-apy and exploration of new modalities of radiation techniques are also necessary.

Objective To study the influence of carbon dioxide pneumoperitoneum on BIS and oxygen metabolism in patients underwent laparoscopic hysterectomy in propofol and sevoflurane anesthesia. Methods 100 cases undergoing laparoscopic hysterectomy were selected in the second hospital of Shandong university and were divided into group A and group B, 50 cases in each group. Group A were received propofol and group B were received sevoflurane anesthesia . The oxygen metabolism index in the two groups were compared before and after pneumoperitoneum. Results The PETCO2 of two groups at the time points after pneumoperitoneum were significantly higher than those before pneumoperitoneum (P<0.05). There was no significant difference of the SpO2 in two groups at the different time points during pneumoperitoneum, The HR and MAP of the group A were significantly lower than that of group B (P<0.05). There were no significant difference of the PETCO2、SpO2 between two groups. Bis in 2 groups maintained a stationary state before and after pneumoperitoneum. There was no significant difference in the period between the two groups. The CjvO2、Lac of two groups were significantly higher than that before pneumoperitoneum (all P<0.05).The CjvO2、Lac of two groups were significantly lower than that before pneumoperitoneum (all P<0.05). The CjvO2 of group A at 40 minutes after pneumoperitoneum were higher than that of group B (P<0.05), and the level of CERO2、Da-jvO2 were lower than that of group B (P<0.05). But there were no difference of the BIS、CaO2 and Lac between two groups. Conclusion Carbon dioxide pneumoperitoneum can affect the BIS and oxygen metabolism in patients underwent laparoscopic hysterectomy. The effect in propofol anesthesia was more significant than that in sevoflurane anesthesia.

Objective To develop a superparamagnetic iron oxide (SPIO)-based MR probe containing vascular endothelial growth factor(VEGF) to investigate their biological and chemical properties and targeting effect of colorectal cancer cells in vitro. Methods The anti-VEGF-SPIO probe was fabricated with VEGF antibody and SPIO through chemical method. Its biological and chemical properties and reflexivity were tested with SDS-PAGE and MRL The SW620 cells incubated with anti-VEGF-SPIO probe for 30, 60 and 90 minutes respectively and compared with marrow mesenchymal stem cell at 37℃. The comparison among groups was conducted by using analysis of variance and LSD-t test. The MRI results were confirmed by the Prussian blue staining. The comparison among groups was performed by analysis of variance and factorial experiment. Results SPIO-based MR probe containing VEGF was successfully contributed and isolated. The reflexivity of anti-VEGF-SPIO probe was 0.0426×10~6 mol/s. The immunofluorescence and prussia blue stain proved high expression of VEGF in SW620 cells. Anti-VEGF-SPIO probe and SW620 cellscombined at 37℃ in vitro MRI proved the SW620 cells incubated with anti-VEGF-SPIO probe appeared hypointense on T_2WI and T_2~* WI.

Objective To characterize the effects of AQP1 expression on kidney damage in rat disseminated intravascular coagulation(DIC) caused by lipopolysaccharide(LPS) dosing. Method Fifty male Wistar rats (clean grade) were randomly assigned into 5 groups of 10 rats. The 10 control rats were dosed with 10 ml of 0.9%NaCl solution by a drip via the vena caudalis within 4 h, and blood and tissues were obtained after treatment completion. In the DIC groups, the rats were dosed with LPS (30 mg/kg body weight in 10 ml of 0.9% NaCl solution) by a drip via the vena caudalis within 4 h, and blood and tissues were obtained at 4, 6, 8 and 10 h. The blood platelet(PLT) count, prothrombin time(PT) , activated partial thromboplastin time(APTT), fibrin(FIB) and D-dimer(D-D) were detected. Hematoxylin and eosin(HE) staining was used to examine the pathologic changes in the lung and kidney tissues of each group (both hematologic parameters and tissue pathologic changes were used to judge the course of DIC). The AQP1 gene expression levels in the kidney tissues from the groups were evaluated by the mRNA levels using RT-PCR. Statistical analyses were performed by the SNK- q method. Results The PLT count, PT, APTT, FIB and D-D examinations revealed remarkable changes in all DIC groups compared with the control group (P < 0.01). The AQP1 mRNA level was significantly decreased in the DIC group at 4 h compared with the control group (P < 0.01) , and further decreased to the minimum level in the DIC group at 6 h. Moreover, cloudy swelling of renal tubular cells was observed at 6 h and cell degeneration and necrosis were observed at 8 h among the DIC groups. Conclusions Downregulation of AQP1 mRNA expression occurred before damage to the renal tubular cells in DIC, indicating that AQP1 expression may be involved in the kidney damage observed in rat DIC.
