Hypofractionated conformal radiotherapy is capable to deliver much higher doses to the cancer than is possible with standard techniques. Recently there is data suggesting that the early stage nonsmall cell lung cancer ( NSCLC) which is not suitable to surgery is likely to benefit from this regimen, with low lung toxicity. Manyphase Ⅰ-Ⅱ studies showed that the patients with locally advanced NSCLC are well-tolerated to hypofractionated conformal radiotherapy. The model of radio-physic and relative clinical studies suggest that hy-pofractionation would not increase the risk of radiation pneumonitis compared to standard therapy.

Objective To investigate cellular and behavioral effects of adenosine A2A receptor antagonist in a rat model of levodopa-induced motor complications.Methods The hemi-parkinsonian rat model was produced by stereotaxically injecting 6-OHDA to right medial forebmin bundle(MFB).Animals were intraperitoneally treated with levodopa 50 mg/kg plus benserazide 12.5 mg/kg twice a day for 22 days levodopa + vehicle.Rotational duration was estimated.After they were sacrificed,the expression of adenosine A2A receptor was observed by immunohistochemistry and Western blot.Results CSC,reversing the shortened rotational duration induced by levodopa,prolonged the rotational duration.This effect was maintained fil the end of the treatment.The chronic levedopa treatment induced an upregulation of adenosine A2A receptor expression in the lesioned striatum (IOD,(11.55±2.75)×104).The subsequent CSC treatment decreased the adenosine A2A receptor expression to the level of control (IOD,(6.02±1.29)× 104) and PD group (IOD,(5.60±1.83)×104>,F=33.31,P<0.05).Conclusion These results suggest that adenosine A2A receptor is probably involved in the development of levodopa induced motor complications and adenosine A2A receptor antagonist could be useful in the treatment of motor comphcations in parkinsonian patients.

BACKGROUND:Tracheal injury suture and the development of a new tracheal prosthesis all need to understand the tensile mechanical properties of tracheal cartilage.so as to repair and rebuild tracheal function.Previous researches on the biomechanics of artificial trachea are many reported.while the biomechanics of human tracheal cartilage is reported less.OBJECTIVE:To investigate the mechanical properties of tracheal cartilage using one-dimensional tensile test method.METHODS:Two fresh cadaver specimens of normal human trachea.with the informed consents of their families.were involved.The specimens were thaw at room temperature,and then tracheal cartilage specimens were cut using scalpel into 20 samples at the length of 25 mm,width 5 mm,thickness 1.8-2.2 mm.The 20 tracheal cartilage samples were subjected to one-dimensional tensile test with Shimadzu electronic universal testing machine Japan,at the tensile test speed of 5 mm/min.The tensile maximum load,maximum displacement,maximum stress,maximum strain,elastic modulus and stress-strain curve of the specimens were observed.RESULTS AND CONCLUSION:The maximum load of human cadaver tracheal cartilage was(60 946±10.377)N,maximumdisplacementwas(1.973±0.159)mm,maximum stresswas(6.229±1.125)Mpa,maximum strainwas(32.825±2.776)%.Tracheal cartilage stress-strain curves was changed along with the index,the initial low slope of the curye was due to the direction of imposed tension was similar with the arrangement of collagen structure,the steep slope represented the tensile strength of collagen.To describe the tracheal cartilage stress-strain relationship in a one-dimensional tension,15 stress-strain data of the tracheal cartilage experimental data adopted polynomial by the least square fitting method,to obtain stress(δ)-strain(ε)relationship forrnula:σ(ε)=-0.111 3e~5+1.602 1e~4-7.821 6e~3+17.995 1e~2+3.624e.It is indicated that tracheal cartilage has a strong capacity to bear Joad and resist deformation,reflecting their viscoelastic mechanical properties of both flexibility and viscosity,supporting that the mechanical properties of cartilage is positively related to cartilage collagen content.

Objective:To reveal the dynamic characteristics of the intracellular complement mRNA from mouse macrophage ANA-1 treated with LPS or IL-4. Methods:The polarization models of macrophage ANA-1 were established by treating with LPS(1μg/ml) and IL-4(20 ng/ml),respectively. After treating at 3,8,12 and 24 h,the total RNA were abstracted by Trizol lysis methods . The macrophage polarization were estimated by the expression of IL-1β, CCL2 and Arg-1 mRNA detected by Real-time fluorescent quantitative PCR. The intracellular complement C1q, C3, CfB and CRIg mRNA were quantitatively analyzed. Results: The mouse macrophage ANA-1 cells treated with LPS was polarized to M1 since the levels of IL-1β and CCL2 mRNA were up-regulated significantly,in which their 2-△△Ct value were up to 297. 0±31. 0 and 19. 9±3. 3 respectively at 12 h. On the other hand,the ANA-1 cells treated with IL-4 was polarized to M2 because the level of Arg-1 mRNA was obviously higher( the 2-△△Ct value of Arg-1 mRNA was up to 27.3±9.1 at 24 h)(P<0.05).The intracellular complement C1q,C3,CfB and CRIg mRNAs all were up-regulated in different polarized macrophages. The intracellular C1q and C3 mRNA in polarized M2 were significantly higher,in which the peak value of C1q and C3 were to 94. 9±12. 9 and 11. 3±2. 4 at 12 h,respectively(P<0. 05). Reversely,the CfB mRNA in polarized M1 increased obviously,in which its 2-△△Ct was to 61. 4±6. 2 at 12 h. In addition,the CRIg mRNA in both groups was only up-regulated at 24 h,in which the 2-△△Ct value was 6. 5±1. 8 in M1 and 10. 8±3. 2 in M2(P<0. 05). Conclusion: The macrophage ANA-1 cell polarization models were successfully established by treated with LPS or IL-4. The intracellular complement C1q,C3 and CRIg mRNA in polarized M2 were transcripted more than in M1. But the intracellular CfB mRNA in polarized M1 was up-regulated significantly. These results suggested that the dynamic characteristic of complement components in different polarized macrophage would be correlated with its fun-tions.
