Background and purpose:Correct target positioning is an important factor affecting the precision of stereotactic body radiotherapy (SBRT) in patients with lung tumors. This study investigated the setup errors in patients with malignant lung tumors receiving SBRT with cone-beam CT (CBCT) and analyzed the factors influencing setup errors.Methods:Twenty-nine patients with solitary malignant lung tumors were enrolled in the study. Each patient underwent SBRT with CBCT before each treatment. Setup errors in CBCT were obtained according to the matched and planned CT images in anterior-posterior (AP), superior-inferior (SI) and left-right (LR) directions. The expanding margins of clinical target volume (CTV) to planning target volume (PTV) according to the analyzed setup errors were then calculated. And the influencing factors of setup errors were analyzed.Results:A total of 155 CBCT images from 29 patients were obtained during the treatment. The setup errors were (-1.68±3.62), (-1.34±3.90) and (0.36±2.15) mm in the AP, SI and LR directions, respectively. The absolute setup errors were (3.16±2.42), (3.29±2.48) and (1.74±1.30) mm in the AP, SI and LR directions, respectively. The suggested expanding margins of CTV to PTV were 9.6, 10.0 and 5.3 mm in the AP, SI and LR directions according to the setup errors. The setup errors in the AP direction of peripheral lesions and in the SI direction of inferior, right and metastatic lesions were relatively larger(P=0.007, 0.008, 0.000 and 0.000)..Conclusion:In patients with malignant lung tumors receiving SBRT, the setup errors were more obvious in the SI and AP directions. Tumor motion management techniques including CBCT, breath-holding technique are required to reduce the setup error in patients with lung tumors receiving SBRT.

In order to improve the teaching reform of higher education systematically and op-erably, and in order to improve the effectiveness of teaching reform, teaching reform in Higher Educa-tion in the micro system engineering and SIMPP analysis method were proposed. With questionnaire survey on classroom learning state of all students from traditional Chinese medicine Grade 2010-2013 of Beijing University as an example, the principle and operation steps of SIMPP analysis method was systematically discussed. According to the students' related behavior pattern and strategy analysis affected by teachers, the analysis of the results of interpretation method and application direction was illustrated. At the same time, through the monograph, nine aspects (academic diligence level, learning effectiveness of self cognition, learning interest, teacher's influence, self-study ability, class atten-dance, learning objectives, curriculum satisfaction, major satisfaction) were analyzed by SIMPP. By modeling the related factors and their relationship, the internal relations between different factors were cleared, and the students' behavior patterns were found, and the corresponding reform measures were designed. Research shows that the concept and methods of teaching reform in Higher Education in the micro system engineering will produce a positive impact on teaching reform, curriculum reform, and the integration of family education and school education.

OBJECTIVETo investigate the effects of exercise (EX), low-fat diet (LFD) and their combination intervention on the tumor necrosis factor-alpha (TNF-alpha) expression of insulin resistance in rats.

METHODSOne hundred and thirty male rats randomly assigned to 2 groups: Control (CON)-10 rats consuming a low-fat diet; HFD-120 rats consuming a high-fat diet (HFD). The dietary regimen was sustained for 8 wk, at which point the 40 HFD group rats gaining the most weight were referred to as the obese rats. Glucose tolerance was assessed by an oral glucose tolerance test (OGTT). During the procedure of OGTT, the blood was drawn for insulin assay (insulin release test). The whole body insulin resistance was assessed by glucose-insulin index. The obese HFD group rats were randomized into one of four intervention groups: HFD-sedentary (HFD-SED), HFD-exercise(HFD-EX), low fat diet-SED (LFD-SED), LFD-EX. Ex rats performed 8-wk exercise training on a motorized treadmill. The CON group had access to low-fat diet for another 8 wk. After 8 wk of exercise and low-fat diet intervention, the OGTT and insulin release test were performed again. To use ELISA technique for detecting TNF-alpha in soleus muscle and adipose tissue.

RESULTSAfter being fed high-fat diet for 8 wk, glucose-insulin index in the HFD group were significantly greater than that in CON group (P < 0.01). After 8-week exercise and low-fat diet intervention, glucose-insulin index in HFD-SED group was significantly greater than that in CON group (P < 0.01). The index in three intervention groups was significantly less than that in HFD-SED group (P < 0.01) . TNF-alpha content in adipose tissue and the soleus muscle for HFD-SED group was significantly greater than that in CON group (P < 0.01). Three intervention groups were significantly less than HFD-SED group (P < 0.01).

CONCLUSIONExercise and low-fat diet interventions can decrease the TNF-alpha expression in insulin resistance rat.
