放射治疗

肿瘤放射治疗是利用放射线治疗肿瘤的一种局部治疗方法。放射线包括放射性同位素产生的α、β、γ射线和各类x射线治疗机或加速器产生的x射线、电子线、质子束及其他粒子束等。大约70%的癌症患者在治疗癌症的过程中需要用放射治疗,约有40%的癌症可以用放疗根治。放射治疗在肿瘤治疗中的作用和地位日益突出,已成为治疗恶性肿瘤的主要手段之一。放射疗法虽仅有几十年的历史,但发展较快。在CT影像技术和计算机技术发展帮助下,现在的放疗技术由二维放疗发展到三维放疗、四维放疗技术,放疗剂量分配也由点剂量发展到体积剂量分配,及体积剂量分配中的剂量调强。现在的放疗技术主流包括立体定向放射治疗(SRT)和立体定向放射外科(SRS)。立体定向放射治疗(SRT)包括三维适形放疗(3DCRT)、三维适形调强放疗(IMRT);立体定向放射外科(SRS)包括X刀(X-knife)、伽玛刀(Y刀)和射波刀(Cyber Knife),X

Passage 2  What do student newspapers complain about these days?  How about this headline in Swansea University’s student paper following the recent bad weather.  “Students lose? 20 a lecture after snow sends university into lockdown.”  It pointed out that fee-paying students are not getting full value for money if lectures are cancelled.  Students were seeing their “money disappear quicker than the snow melted”.  It illustrates something about changed attitudes on campus when students are complaining that they are not getting enough lectures.  Paying fees means that students are customers as well as learners.  The student union president at Swansea University, James Houston, says that going to university is “still different from a shopping experience”—but that paying fees is pushing it in that direction.  “There is a strong argument that if you charge more, then people will want to know where their money is going” he says.  Universities are more than a business, he says. But he fears that fees are driving a campus consumer ethic.  The students’ union already has complaints from students about not getting “value for money”.  This shift in attitude is also reflected in an increase in complaints by students to the Office of the Independent Adjudicator for Higher Education—which it attributes to fees.  “We believe that one reason for the increase is the rise in tuition fees. There is also more consumerist thinking amongst students. Students have become more assertive about their rights, and the services they are entitled to,” said chief executive, Rob Behrens.  While the debate about fees was once about whether it would be a social barrier to poorer students, in practice there have been other less expected changes.  The combination of fees and debts from student loans means that university courses are judged by their price tags as well as academic worth.  Frank Furedi, social commentator and academic at the University of Kent, says that the campus culture is “unrecognisable” from a generation ago.  Students now ring lecturers at home at the weekend, he says, seeing this as being part of the service they are buying with their fees.  “They feel they can make all kinds of demands,” says Prof Furedi.  “Fees give a clear and tangible form to the idea of students as consumers.”  “The relationship with the student is no longer academic, it’s a service provider and customer.  The academic relationship is an endangered species.”  But the landscape is one in which many students expect to have everything done for them.  “School has extended into higher education. Students behave like schoolchildren.”  If tuition fees are hiked further, he says it will intensify the sense of consumerism among students.  There are other signs of how fees have changed life on campus.  Students are more careers-focused than ever before, the accumulation of large debts putting pressure on them to get a degree that will help them in the jobs market.  Beginning a university degree course is a serious financial undertaking and that now shapes the experience of student life.  There are other practical changes. More students than ever are living at home while at university—with surveys suggesting that perhaps a fifth of students continue to live with their parents.  This in turn means that more students, particularly from less well-off families, are choosing from universities close to where they live.  The role of parents, who pay towards student costs, has also been seen as becoming more prominent.  This has been caricatured as “helicopter parents” who hover over every decision taken by their student offspring, including contacting lecturers.  Parents can now act as agents for their children in university applications—and have even been allowed to sit in on admissions interviews.  Cary Cooper, pro-vice chancellor at Lancaster University, also points to the structural consequences of a further increase in fees.  At present, he says, the current level of student debt means that many more students have to take part-time jobs to pay their way.  Another hike in fees will mean even more students will need to work—including those who will only be able to study part-time.  This will mean universities will have to adapt, such as providing courses which can be passed in individual units, accumulating credits over a number of years.  Professor Cooper says this could mean a fundamental change for higher education, moving away from the traditional model of 18 to 21-year-olds taking a three-year degree course.  1. Describe Frank Furedi’s viewpoint of the present relationship between professor and student and the reason.  2. How do the hiked fees change students’ choice of majors and universities?  3. What changes are likely to happen if there is another jump in tuition fees?
