It has been realized that the 4Rs (repair,repopulation,redistribution,and reoxygenation) would affect the result of cell irradiation,and thus radiation treatment.The 4Rs each occurs at different dose rates,usually very low dose rates.Depending on the dose rate used for treatment,the corresponding R should be included in the linear-quadratic equation (LQ) and biological effective dose (BED) calculation.For low dose rate brachytherapy(LDR) especially permanent implant,all the 4Rs should be included in LQ for BED calculation.The 4Rs,especially repair and repopulation,play a critical role in dose fractionation.Various dose fractionation schemes such as hyperfractionation and hypofractionation are determined in consideration of the 4Rs.Stereotactic radiation therapy uses hypofractionation with high fractional doses and combine with high accuracy target localization techniques to achieve high local control rates compared to conventional dose fractionation schemes.The 4Rs have been taken into account for LDR and permanent implant.Recently,LQ for permanent implant brachytherapy has been modified to include all the 4Rs for gynecological malignancy 131Cs permanent implants.Including the 4Rs in radiation therapy has significantly improved the effectiveness and efficiency of radiation therapy for cancer treatment.

Objective To evaluate clinical value of tumor biomarkers in ascitic fluid and serum in differentiating benign from malignant ascites and their correlation. Methods From July 2006 to July 2009,67 patients with ascites undergone abdominal paracentesis in Renmin Hospital of Wuhan University were enrolled in the study and divided into malignant and benign groups according to their etiology. Levels of tumor biomarkers in ascitic fluid and serum were determined and their correlation were analyzed. Diagnostic sensitivity and specificity of tumor markers were evaluated. Results There was statistically significant difference in levels of cancer antigen 199 (CA199) in serum and ascitic fluid between the malignant group and the benign one ( P ＜ 0. 01 ), and level of cancer embryonic antigen (CEA) significantly increased in ascitic fluid (P ＜ 0.05 ). Levels of CA199 and CEA in serum were significantly higher than those in ascetic fluid in the benign group (P ＜ 0. 01 and P ＜ 0. 05 ), and level of CA125 was significantly lower in serum than that in ascitic fluid (P ＜ 0. 01 ). Level of alpha-fetal protein (AFP) in serum significantly correlated with that in ascitic fluid in the benign group (r =-0. 992, P ＜0. 01 ). In the malignant group, levels of CA199, CEA and CA125 were significantly higher in ascitic fluid than those in serum (P ＜0.05 or P ＜0. 01 ). Levels of CA199 and CEA in serum significantly correlated with those in ascetic fluid in the malignant group (r =0. 746 and 0. 572, respectively, P ＜0. 01 ), and level of AFP in serum also correlated with that in ascetic fluid (r=0. 384, P ＜0. 05). Ratios of levels of CA199 and CEA in ascetic fluid to those in serum (F/S) were significantly higher in the malignant group than those in the benign group (P ＜0.05 or P ＜0.01). Use of combination of CA199, CEA and CA125 determinations showed a higher sensitivity and specificity in differential diagnosis for benign and malignant ascites (P ＜0.05). Conclusions Determinations of CA199 and CEA are beneficial for differentiating benign ascites from malignant one. Determinations of tumor biomarkers in serum can not fully replace those in ascetic fluid. Combined determinations of CA199, CEA and CA125 can increase their sensitivity and specificity in diagnosis for malignant ascites.

Objective: To evaluate the compensation level of the Urban Employee Basic Medical Insurance ( UEBMI ) and Urban Resident Basic Medical Insurance ( URBMI ) in Jiangsu province . Methods: Take catastrophic health expense as the bottom line of compensation ratio for the basic medical insurance, the benefit of hospitalization expenses of those joining the insurance as the actual line of compensation ratio, and quartile division was used to comparatively analyze the differences between the bottom line of compensation ratio and the actual line of compensation ratio. Results: Take 10%as the critical value of catastrophic health expense, the actual line of compensation level is higher than the bottom line of compensation level in UEBMI, and there is reverse in URBMI. Conclusion: In some extent, the compensation level of UEBMI has relieved the economic burden of the poor jointed group because of sickness, while limited compensation level of UEBMI is in need of further improvement.

To examine the role of glycogen synthase kinase 3 (GSK-3) in the apoptosis of pancreatic beta-cells to better understand the pathogenesis and to find new approach to the treatment of type 2 diabetes, apoptosis was induced by oleic acid (OA) in INS-1 cells and the activity of GSK-3 was inhibited by LiCl. The PI staining and flow cytometry were employed for the evaluation of apoptosis. The phosphorylation level of GSK-3 was detected by Western blotting. The results showed that OA at 0.4 mmol/L could cause conspicuous apoptosis of INS-1 cells and the activity of GSK-3 was significantly increased. After the treatment with 24 mmol/L of LiCl, a inhibitor of GSK-3, the OA-induced apoptosis of INS-1 cells was lessened and the phosphorylation of GSK-3 was increased remarkably. It is concluded that GSK-3 activation plays an important role in OA-induced apoptosis in pancreatic beta-cells and inhibition of the GSK-3 activity can effectively protect INS-1 cells from the OA-induced apoptosis. Our study provides a new experimental basis and target for the clinical treatment of type-2 diabetes.
