Methods Under aseptic condition, mechanically blocking of the hepatoduodenal ligement was adopted in rabbit model, both endotoxin level of the portal blood and positive bacterial cultures in the mensenteric lymph nodes were observed at 15, 20, 30 and 60 min respectively after the blocking. Results Both endotoxin level and positive bacterial cultures increased significantly (P

Objective Using Eclipse and Pinnacle3 V 7.4f treatment planning sytems (TPS) for dose calculation of the CT images of simulation phantom,patients and homogeneous organization phantom,to compare the differences between the two TPS for the calculation of non-uniform organizations.Methods For the CT images of simulation phantom,patients and homogeneous organization phantom,the calculating results between the two TPS were compared,including the common used clinical indexes of V20 and V30 of the lung,D95 of the planning target volume,the doses of the ISO and eight points of interest inside ISO slice.Resuits For simulation phantom and patients,although the calculating differences of the isocenter doses between the two TPS were small,the differences of other indicators were large.For example,when using secondary collimator irradiation,the maximal D95 difference of planning target volume reached 10.17%for patients and 4.64%for simulation phantom.When using muhileaf collimator irradiation,the maximal D95 difference reached 10.74%for patients and 5.66%for simulation phantom.Sometimes the dose differences of points 1-4 at the edge of planning target volume were more than 10%.In addition,the V30 differences of the lung were large too.But for the homogeneous organization phantom,the calculating differences were small.Conclusions The calculating differences between the two TPS are less for simulation phantom than for patients,and more for simulation phantom and patients than for homogeneous organization phantom.

Objective To quantify the effect of 650 nm semiconductor laser irradiation on cutaneous wound healing in rabbits. Methods Model wounds were induced in 21 adult male rabbits. They were then divided randomly into a control group, a 5 mW irradiation group and a 10 mW irradiation group. Biometry and light microscopy were used to investigate the effect of low intensity laser therapy (LILT) on cutaneous wound healing. Results Statistically significant differences were observed among the groups in terms of wound shrinkage. The differences between the irradiated and control groups were significant at the 5th, 9th and 13th day. However, any differences between the S mW and 10 mW groups were not significant. Conclusions LILT at 650 nm at either 5 mW or 10 mW and 1 J/cm2 accelerates cutaneous wound healing in rabbits. But irradiation at 10 mW is no more effective than at 5 mW.

Objective To assess the feasibility for the automated treatment planning verification system Mobius3D (M3D) to perform an independent 3D dose calculation in intensity-modulated radiotherapy (IMRT) for cervical cancer.Methods Twenty patients with cervical cancer were randomly selected.With treatment planning systems (Pinnacle,Version 9.2;Eclipse,Version 13.5),all IMRT plans were divided into 7 fields to meet the dosimetric goals.The optimized plans were exported to the M3D server.The percentage differences in the volume of region of interest (ROI) and the dose calculation of target volume and organ at risk (OAR) were evaluated for the two treatment planning systems,and theγ passing rate was used to assess the accuracy of M3D calculation.Results The difference in the volume of ROI for Pinnacle 9.2 to M3D was less than that for Eclipse 13.5 to M3D,with maximum differences of 0.22％±0.69％ and 3.5％±1.89％ for Pinnacle 9.2 and Eclipse 13.5,respectively.The differences in the dose calculation of target volume and OAR for the two treatment planning systems to M3D were within ± 1％.After recalculating by M3D,the dose difference between Pinnacle 9.2 and M3D was smaller than that between Eclipse 13.5 and M3D,but the mean differences were all within ±3％.The γ passing rates for target volume and OAR were more than 95％ on average.Conclusions The method of utilizing the automated treatment planning verification system to validate the accuracy of plans is convenient.It can be used as a secondary check tool to improve accuracy in IMRT dose calculation.

Objective To explore the influence of different reconstruction modes with time?weighted respiratory phases on the internal tumor volume ( ITV) of solitary pulmonary lesion ( SPL) , and to evaluate the feasibilities of 8 and 4 equal time?weighted respiratory phases in 4DCT simulation. Methods 24 patients with SPL underwent 4D scanning. Images were reconstructed with 10, 8 and 4 equal time?weighted phases of the respiratory cycles, respectively. Gross tumor volumes ( GTVs ) were delineated on the three sets of reconstructed images and fused into ITVs, which were ITV10 , ITV8 and ITV4 respectively. The differences of volumes, centroid of the ITVs and motions of GTV centroids in three?dimensional directions were compared. Statistical analysis was performed using the Friedman M test. Results The volumes of ITV10 , ITV8 and ITV4 were (9.09±12?29) cm3,(9.10±12?47) cm3 and (8.98±12?61) cm3(P=0?001), respectively. There were no differences between the volumes of ITV10 and ITV8 after the Bonferroni correction ( P=0?721) , while the opposite between those of ITV10 and ITV4 ( P=0?002 ) . The differences of centroid positions of ITV10, ITV8 and ITV4 in x?, y?and z?axes were all less than 1 mm ((12.22±7?71),(12.23± 7?71),(12.22±7?71),Px =0?668);(43.30±29?38),(43.30±29?40),(43.31±29?39),Py =0?643;(5.66±3?67),(5.66±3?67),(5.66±3?67),Pz=0?878), similar to the motions of GTV centroids in three reconstructed modes ((0.69±0?56),(0.69±0?68),(0.79±0?51) mm,Px=0?356;(3.13±3?78),(3.13± 4?05),(3.19±4?06) mm,Py =0?978;(1.18±1?31),(1.03±1?32),(1.16±1?34) mm,Pz=0?302). Conclusions There were no differences in volumes, centroid positions and motions between ITV10 and ITV8 . The quantity of reconstruction images and GTV delineations according to 8 time?weighted phases were both less than conventional 10 phases. 8 time?weighted respiratory phases mode was feasible in 4DCT simulation for SPL.

Objective To observe the anti-atherosclerosis (AS) mechanisms of Shuxinwenban granules by observing its effects on the serum level of MMP-9, the expression of VEGF and the formation of the plaques in rabbits. Methods Totally 40 healthy female and male rabbits were divided into control group, model group, Shuxinwenban granules group and Simvastatin group. Control group was treated with basic diet, and other groups were treated with high cholesterol diet for 12 weeks to make AS rabbit models. The treatment groups were given corresponding drugs by gavage for 4 weeks. The serum levels of MMP-9 in rabbits were detected by double antibody sandwich enzyme-linked immunosorbent method and the surface density of VEGF in the atherosclerotic plaques by immunohistochemical staining, at the same time, the pathological changes of the aorta and atheroclerotic plaques were observed. Results Compared with the model group, Shuxinwenban granules significantly decreased the serum levels of MMP-9, and the difference was statistically significant (P <0.01). Similarly, Shuxinwenban granules could significantly decrease the surface density of VEGF in atherosclerotic plaques, the difference was also statistically significant (P<0.01). Pathology showed that the intervention of Shuxinwenban granules decreased the area of atherosclerotic plaque, caused the plaque to smaller and thinner. Conclusion Shuxinwenban granules blocked the inflammatory response by inhibiting the expression of VEGF in atherosclerotic plaque and decreasing the levels of MMP-9 in serum, which lessened the formation of the atherosclerotic plaques.
