Objective To evaluate the dose distribution of target volume and normal tissues with different treatment planning such as three dimensional conformal radiotherapy(3DCRT) ,simplified intensity modulated radiotherapy(sIMRT) ,and intensity modulated radiotherapy (IMRT) for patients with radically resected rectal cancer. Methods Ten male patients with stage Ⅱ and Ⅲ rectal cancer after radical resection (Dixon surgery) were enrolled in this study. 3-field or 5-field 3DCRT,slMRT and 5-field or 7-field IMRT plans were performed for each patient. The dose distributions of target volume and normal tissues,conformal index(CI) and heterogeneous index(HI) were analyzed using the dose-volume histogram(Dvit). The prescription dose was 50 Gy in 25 fractions. Results The CI for PTV of IMRT and sIMRT was superior to 3DCRT. Conversely,the HI for PTV of 3DCRT was superior to sIMRT and IMRT. sIMRT and IMRT can protect the organs at risk better than 3DCRT. The mean of total MU for 3DCRT3f,3DCRT5f, sIMRT, IMRT5f and IMRTT7f was 482±13,504±11,455±42,841±36 and 884±46, respectively. Conclusions Comparing with 3DCRT plans and IMRT plans, sIMRT plan was the optimal plan for clinical practice. All of the three radiotherapy techniques can protect the rectal stump and anal canal well with the prescription dose of 50 Gy.

BACKGROUND: As a convenient and useful physical activity measurement tool,pedometer is widely used in research and intervention about physical activity of population. OBJECTIVE: To assess validity and reliability of the pedometer in measuring daily physical activity. DESIGN,TIME AND SETTING: The experiment was performed at the Department of Kinesiology,Nanjing Institute of Physical Education and Sports from April to June 2007. PARTICIPANTS: Thirty college students,15 majoring in Kinesiology and 15 majoring in social and physical education,15 females and 15 males,with an average age of (20?1) years,were selected from Nanjing Institute of Physical Education and Sports. METHODS: Participants wore a Digi-Walker200 for one week to record results of pedometer measurement,and filled in Bouchard Physical Activity Diary every day to note activity in 24 hours and calculate energy consumption. All participants completed International Physical Activity Questionnaire including large and moderate intensity activity,walking and sitting in a week. MAIN OUTCOME MEASURES: Daily steps,energy expenditure,sedentary time,waking time,exercise time,and weekly physical activity condition. RESULTS: Step counts were positively correlated with daily energy expenditure,walking time,and exercise time,and negatively related with sedentary time. Step counts of different physical activity levels were significantly different: more step counts could better reflect physical activity levels. Furthermore,exercise or continuous walking (more than 15 minutes) could significantly increase step counts. Daily physical activity including 30-minute moderate intensity activity could achieve or exceed the target steps of 10 000. CONCLUSION: Pedometer provides a useful and objective indicator of daily step counts assessing daily physical activity,but it is difficult to reflect activity intensity and patterns.

The leucoanthocyantin reducase (LAR) gene, an important functional gene of catechins biosynthesis pathway, was cloned from Fagopyrum dibotrys (D.Don) Hara by degenerate PCR and rapid amplification of cDNA ends (RACE). The full-length cDNA of FdLAR is 1 581 bp (GenBank accession: JN793953), containing a 1 176 bp ORF encoding a 391 amino acids protein, and its 3'-untranslated region has an obvious polyadenylation signal. The recombinant plasmid containing FdLAR completed ORF was transformed into E. coli BL21 (DE3). The target fusion peptide with molecular weight of 66 kD was expressed under the condition of 16 degrees C and induced by IPTG at final concentration of 1.0 mmol x L(-1). Bioinformation analysis indicated that the amino acid sequence of FdLAR showed great homology to other LAR with the NADB-Rossmann conversed domain in the N-terminus. Real-time quantitative PCR was used to detect the expression levels of FdLAR gene during different development periods. The determination of flavonoids contents in appropriate rhizomes showed that the relationship between FdLAR gene expression and the accumulation of flavonoids displayed different trends during vegetative growth and reproductive growth stages, suggesting that the FdLAR gene may be involved in the pathway of flavonoid metabolisms in Fagopyrum dibotrys.
