Objective: To seek the direct evidence of myocardial inflammatory activation in a cohort of patient undergoing surgery on cardiopulmonary bypass (CPB). Methods: Twenty patients undergoing surgery on CPB had plasma samples obtained for tumor necrosis factor-? (TNF-?), perioperatively. Myocardial tissue samples were obtained intraoperatively, both pre-and post-CPB. Myocardial nuclear factor ?B (NF-?B) nuclear translocation and plasma TNF-? concentrations were analyzed by standard enzyme-linked immunosorbent assay (ELISA). Cross clamp times, CPB times and the time to extubation were recorded. The change of myocardial NF-?B nuclear translocation and plasma TNF-? concentrations was assessed by analysis of variance (ANOVA). The regression analysis was utilized to define the correlations among the optical densities of NF-?B, concentrations of plasma TNF-?, influencing factors and heart function. Results: (1) Seventeen patients had NF-?B nuclear translocation before initiation of CPB, the optical density (OD) of myocardial NF-?B was significantly increased at the end of CPB in nineteen patients. (2) The correlation between the activity of NF-?B and concentration of TNF-? was signi ficant. (3) The correlation between the activity of NF-?B and clinic outcomes and other influencing factors was not significant. Conclusion: Myocardial inflammatory activation may be present in the patients before CPB. CPB could increase the activity of myocardial NF-?B.

Objective To compare the dosimetry between inversely optimised intensity-modulated radiotherapy (IMRT) and three-dimensional conformal radiotherapy using the field-in-field technique (FIF) for whole-breast radiotherapy with a boost to the tumor bed after breast-conserving surgery.Methods IMRT and FIF treatment plans were respectively performed and optimised for 9 patients with early stage leftbreast cancer after breast-concerving surgery.The prescribed dose of breast was 50.4 Gy in 28 fractions,1.8 Gy per fraction and that of tumor bed was 61.6 Gy in 28 fractions,2.2 Gy per fraction.The conformity index,the dose and volume for OAR( organs at risks),time of planning and treatment for the two plans were compared.Results The conformity index(CI) for IMRT was improved compared with the FIF in breast [(1.82±0.16) vs.(2.21±0.15)] and tumor bed [(1.19±0.04) vs.(1.59±0.11),t=2.08,3.97,P ＜ 0.05 ].There was no difference for V20 of ipsilateral lung and V30 of heart between two plans.The Dmax and Dmean of the contralateral lung of FIF were (5.41 ±2.76) and (0.51 ±0.10) Gy,lower than those of IMRT [ (25.72 ± 2.61 ) and (7.46 ± 0.39) Gy,t =-22.44,- 21.14,P ＜ 0.05 ].The Dmax and Dmean of the contralateral breast of FIF were (8.50 ± 5.61 ) and (0.47 ± 0.11 ) Gy,lower than those of IMRT [(27.73±4.30) and (6.38±0.48) Gy,t=-5.66,-14.83,P＜0.05].ForFIF,theV5of the contralateral lung and breast were (0.09 ± 0.09) ％ and (0.45 ± 0.45 ) ％,respectively,lower than those of IMRT,which were (84.66 ±3.06) ％ and (60.79 ±4.94)％ (t =-28.19,- 12.80,P＜0.05).The time of optimised plan was (61.57 ± 0.89) min for FIF and(241.28 ± 1.06) min for IMRT (t=-32.35,P＜0.05),and that of treatment were (16.14±1.42) min for FIF and (29.85 ±0.59) min for IMRT (t =- 8.82,P ＜ 0.05).Conclusions For patients with early stage breast cancer after breast-concerving surgery,IMRT could improve the conformity index of target but increase the dose of eontralateral lung and breast.However,FIF has advantage on the time of optimising plan and treatment.

Objective To assess the differences in delineation of organs at risk (OAR) and dosimetry between junior and senior physicians during intensity-modulated radiation therapy (IMRT) for nasopharyngeal carcinoma (NPC) and to evaluate the role of specific training in reducing the differences.Methods Sixteen patients newly diagnosed with NPC were selected in the study.The OAR was delineated separately by three junior physicians and three senior physicians,and the geometric and dosimetric differences were assessed relative to the reference OAR.Delineation was performed again for the two OARs with the biggest difference after specific training in the two groups of physicians,and the differences were evaluated again.The difference was determined by paired t test.Results The maximum dose differences (Dmax) of OAR in the junior and senior physicians were (2.33 ± 12.06) ％ (-48.06％-137.82％) and (0.09 ± 4.72) ％ (-49.54％-42.96％),respectively (P =0.039),and the difference in the optic chiasm was the greatest ((5.85 ± 19.63) ％ ∶ (1.36 ± 4.64) ％,P =0.042).The mean dose differences (Dmean) of OAR in the junior and senior physicians were (3.10 ± 8.07)％ (-46.76％-59.76％) and (-0.93 ± 2.03) ％ (-45.54％-35.69％),respectively (P =0.021),and the difference in the parotid gland was the greatest ((13.23 ± 13.39) ％ ∶ (3.20 ± 6.71) ％,P =0.002).In the secondary delineation after training,the Dmax of the optic chiasm in the junior and senior physicians was (1.68 ± 3.34)％ and (1.50 ± 1.87) ％,respectively (P =0.841),and the difference in junior physicians was reduced significantly compared with before training ((1.68 ± 3.34) ％ ∶ (5.85 ± 19.63) ％,P =0.048) ; the Dmean of the parotid gland in the junior and senior physicians was (2.46 ± 3.06) ％ and (1.35 ± 3.00) ％,respectively (P =0.2 7 4),significantly reduced compared with before training ((2.46 ± 3.0 6) ％ ∶ (13.23 ± 13.39)％,P=0.002; (1.35 ± 3.00)％ ∶ (3.20 ± 6.71) ％,P =0.033).Conclusions The differences in delineation of OAR lead to dose uncertainties during IMRT for NPC,and specific training can improve the accuracy of delineation.

Objective To identify clinicopathologic factors which predict survival following hepatectomy in HBV-related cirrhotic patients with early hepatocellular carcinoma (HCC).Methods A database was used to identify patients with histologically confirmed early HCC (≤5 cm,no nodal involvement,metastases,or major vascular invasion) who underwent surgical resection (excluding ablation or transplantation).Among 20 700 patients with HCC who were diagnosed at the Eastern Hepatobiliary Surgery Hospital from April 2005 to November 2010,537 (2.6％) patients with early HCC were studied retrospectively.Prognostic factors were evaluated using the Kaplan-Meier curves,Cox proportional hazards models and the receiver operating characteristic (ROC) curves.Results The study included 537 patients.The median tumor size was 2.9 cm,and 33％ of patients had tumors ≤2 cm.Most HCC lesions were solitary (63％) and had no evidence of vascular invasion (64％).Following surgery,the overall median and 5-year survival were 45 months and 33％ respectively.After adjusting for demographic factors and histological grade,tumor size ＞2 cm (hazard ratio [HR]:1.56),multifocal tumors (HR:1.34),and vascular invasion (HR:2.03) remained independent predictors of poor survival (all P ＜ 0.05).Based on these findings,a prognostic scoring system was developed that allotted 1 point each for these factors.Patients with early HCC could be stratified into 4 distinct prognostic groups (median and 5-year survival,respectively):0 points (97 months,96％),1 point (85 months,76％),2 points (76 months,54％),3 points (56 months,39％) (P ＜0.01).Conclusions The present study emphasized the importance of pathologic staging even in patients with small HCC.Anatomical resection of HCC should be the preferred surgical procedure in cirrhotic patients.
