Objective To measure the setup errors of patients with esophageal carcinoma during the treatment of three dimensional conformal radiotherapy (3DCRT), and to analyze the impact of setup errors on dose distribution of GTV,CTV and normal tissues around. Methods Forty-two patients with esophageal cancer treated by 3DCRT were included. The setup errors of each patient were measured once a week for 6 times by electronic portal imaging device (EPID). The setup errors were integrated into the treatment plan-ning system by moving the isocenter. Then the dose distribution of GTV, CTV and normal tissues were recal-culated. Results The systematic setup errors of the 42 patients were - 2.31 mm, - 0.55 mm and - 0.16 mm, and the random errors were 4.42 mm, 4.35 mm and 4.48 mm in the directions of lef-fight, anterior-posterior,and superior-inferior, respectively. The dose covered 95% GTV( D95 ) was reduced by 32 cGy and by 88 cGy for CTV D95. The lung V20 in the original plan and the integrated plan was 22.49% and 22.02%, respectively. The average dose of the heart in the two plans was 2077.62 cGy and 2036.23 cGy, respectively. In the original plan, no patient had maximum dose of spinal cord over 4500 cGy; While in the intergrated plan there were 18 patients had the spinal cord dose more than 4500 cGy, with a maximum dose of 5503.90 cGy. Conclusions The setup errors cause significant dose reduction of GTV and CTV, but not of the lung and heart . The maximum dose of the spinal cord may exceed 4500 cGy due to the setup errors.

Objective To investigate the incidence of electrocoagulation syndrome after endoscopic submucosal dissection (ESD) in the colorectal laterally spreading tumors (LST) and the risk factors. Methods Data of 51 patients with coloretral LST,treated with ESD from January 2010 to May 2014 at Shengjing hospital affiliated to China Medical University,were reviewed.The incidence of electrocoagulation syndrome was analyzed and logistic regression was used to evaluate risk.Results The incidence of electro-coagulation syndrome was 9.8%(5 /51).The incidence of tumors in the rectal area(7.1%,2 /28)was lower than that of the left half colon (12.5%,1 /8),and the right colon (13.3%,2 /15).Multivariable logistic regression analysis showed that the independent risk factors for the development of electrocoagulation syndrome were LST located in non-rectum area (OR =1.655,P <1.655),lesion size larger than 25 mm (OR =1.028, P <0.05),the operation time longer than 129 min (OR =1.016,P <0.05),age older than 62 year old (OR =0.987,P <0.05).Conclusion For the patients aged over 62 year old,lesion size larger than 25 mm,the operation time longer than 129 min and LST located outside the rectum,the mucous membrane should be separated from the muscularis propria in the ESD procedure to reduce electrocoagulation time as much as possible. In the postoperative period,patients need fasting,fluid replacement support,and prevention of post endoscopic submucosal dissection electrocoagulation syndrome (PEECS).

Objective To study the pattern of lymphatic metastasis in patients with thoracic esopha-geal carcinoma, and to determine the indication and the target volume for post-operative radiotherapy. Meth-ods 229 patients with thoracic esophageal carcinoma who had undergone radical esophagectomy and two-field lymph node dissection were included in this study. The pattern and ratio of lymph node metastasis were analyzed. The effect of the tumor length and pathology stage on lymph node metastasis was studied. Then the indication and target of post-operative radiotherapy for the thoracic esophageal carcinoma was determined. Results Regional lymph node metastasis was found in 57.1% patients with upper thoracic esophageal car-cinoma. For the middle thoracic esophageal carcinoma, the ratio of regional metastasis, skip, upward, down-ward and two-way spread were 39.0%, 19.5% ,5.2% ,28.6% and 7.8% ,respectively. For lower thoracic esophageal carcinoma,downward spread was found in 77.2% patients. For upper thoracie esophageal carci-noma,the proportions of patients with lymph node metastasis were 19.0% ,6.7% ,9.8% and 14.3% in the superior mediastinum, middle mediastinum, inferior mediastinum and abdominal cavity ( x2 = 2.75, P = 0.433). The corresponding figures were 26.1% ,7.4% ,11.8% and 11.9% (x2 = 17.98,P =0.000) for middle thoracic esophageal carcinoma,and 0%, 1.6% ,5.3% and 10.0% (x2= 5.96 ,P = 0. 051 ) for low-er thoracic esophageal carcinoma. The lymph node metastasis ratios were 9.1%, 11.6% and 11.7% in pa-tients with tumor ≤3 cm,3-5 cm and ≥5 cm,respectively (x2 =3.93,P=0. 140), and were much higher in stage Ⅲ disease than those in stage 0 to Ⅱ (19.3% vs4.8% ;x2 =131.06,P=0.000). Conclusions he pattern of lymph node metastasis is complex and extensive in patients with thoracic esophageal carcinoma. For upper and middle thoracic esophageal carcinoma, the extended prophylactic portal is suggested and the superior mediastinum is an important target area. For the lower thoracic esophageal carcinoma,it seems that regional fields could be applied. Post-operative radiotherapy should be performed in stage Ⅲ disease because of the high lymph node metastasis ratio.

Objective Atherosclerosis is widely accepted as a chronic inflammatory disease. Serum biomarkers for vulnerable plaques not only serve as diagnostic tools for the identification of patients with acute coro-nary syndrome, but also assist the identification of high-risk patients. However, the existing data are limited and conflicting. In the present study, we determined whether the plasma levels of interleukin-1β (IL-1β) are correlated with adverse cardiac outcomes in patients with ST-evaluate acute myocardial infarction (STEAMI) undergoing pri-mary percutaneous coronary intervention (PCI). Effect of the plasma intedeukin-1β level on prognosis of patients with ST-segment elevation acute myocardial infarction. Method This prospective single-center study included 96 patients with SIEAMI with onset < 12 h who underwent primary PCI, 271 patients with stable angina pectoris (SAP) and 148 control subjects without coronary artery disease who were consecutively admitted to hospital be-tween Mar, 2006 and Mar, 2008. Plasma IL-1β levels were measured by enzyme-linked immunosorbent assay in all subjects. The patients with STEAMI were then followed prospectively for the occurrence of major adverse car-diac events (MACE) (including cardiovascular death, non-fatal myocardial infarction, heart failure, and cardio-genie shock) during hospitalization. We determined the association between IL-1β levels with the risk of MACE using multivariate logistic regression. Results Compared with the SAP patients and control subjects, patients with STEAMI had higher levels of IL-1β (P < 0.05). During hospitalization, 32 patients (33.3%) experienced MACE [23 males, 9 females; age: (75.44±13.45) years]. In the STEAMI patients, IL-1β was elevated in patients with MACE compared with patients without MACE (median [range]: 26.52 [12.010 to 155.244] pg/mL vs 2.157 [0.433 to 83.021] pg/mL; P < 0.01) by non-parameter analysis. Significant and positive correlations be-tween IL-1β and cardiac troponin-I (cTnI) (r = 0.353, P =0.004) were observed by Spearman's correlations analysis. Multivariate logistic regression analysis revealed that IL-1β levels ≥20 pg/mL were significantly and in-dependently associated with MACE during hospitalization (odds ratio: 32.05; 95% confidence interval: 4.28 to 240.151; P =0.001). Conclusions The present study revealed that patients with STEAMI had elevated IL-1β levels on admission. The plasma IL- 1β level is an independent inflammatory predictor for in-hospital MACE in pa-tients with STEAMI undergoing percutaneous coronary intervention.
