Objective To compare the characteristics of dose distribution between hypofractionated intensity modulated radiotherapy (IMRT) and hypofractionated stereotactic radiotherapy (SRT) plans in lung tumor and to select an optimal clinical approach. Methods SRT plans were designed for 16 patients with lung tumors who had received IMRT between April 2007 and April 2008. The dose distribution of target volume and normal tissues, conformal index (CI) and heteregenous index (HI) were analyzed using the dose-volume histogram (DVH) for the IMRT and SRT plans. Results The mean dose and equivalent uni-form dose of planning target volume (PTV) in IMRT were similar to those in SRT. SRT had significantly better CI and HI than IMRT (t = 2.77, P < 0.05 and t = - 4.38, P < 0.01 ). The mean lung dose of IMRT and SRT was (492.4 ±368.5) cGy and ( 310.0 ± 73.1 ) cGy, respectively ( t = 1.68, P > 0.05 ). The lung V20 of IMRT and SRT was 6.9% ± 2.1% and 4.2%± 1.9%, respectively ( t = 3.30, P < 0.01 ). No sig-nificant differences were found in the mean dose to the heart or the spinal cord between IMRT and SRT. Conclusions When PTV is less than 57 cm3 or the long diameter of tumor is less than 4.7 cm, hypofrac-tionated SRT has similar dose distribution to hypofractionated IMRT, while the lung dose was lower in the former.

Objective To discuss the characteristics and clinical results of rotating platform high flexion(RDHF)total knee replacement TKR. Methods A total of 61 patients(78 knees)including 13males(15 knees)and 48 females(63 knees)at age range of45-79 years(mean 64.3 years)were treated with Sigma(RP-HF)rotating platform high flexion total knee replacement.Osteoarthritis was found in 56patients and rheumatoid arthritis in 5.By medial parapatella approach,denervation and facet repair of the patella were done,without replacing them. Results All 78 knees were followed up for 3-16 months (mean 10.5 months).the X-ray film demonstrated no prosthesis loosening,patella dislocation or subluxation.According to the knee society scoring system,the preoperative score was 48 points(33-72 points)and the knee functional score was 41 points(28-63 points)on average.After surgery,the knee score was 97points(88-100 points),the functional score 96 points(84-99 points),and the range of motion(ROM)130.(110.-150.)on average.No spin-out or infection were detected. Conclusions The Sigma RP-HF knee system provides sufficient contact area.full range of patella locus and sufficient axial rotation,which helps reach a stable and durable high flexion performance.Our short-term clinical follow up result is good but the advantages of low wear and longevity of the Sigma RP-HF prosthesis still need further study.
