氦-氖激光照射对人体免疫活性细胞的影响

氦-氖激光对促进皮肤溃疡愈合有良好作用，已为临床工作者所熟悉，但其作用机理尚无定论。为进一步探讨溃疡愈合的机理，我们在以氦-氖激光治疗皮肤溃疡的同时，观察了它对人体免疫活性细胞的影响，现小结如下。     

组织对低功率激光的定性和定量反应

Galletti在第三届国际激光会议（1985年瑞士）报告，为了验证组织对激光的反应究系定性的和／或定量的，他们研究了动物模型和病人经He—Ne、二极管，以及低功率CO2等激光照射后组织愈合的方式和时澡。     

氩激光治疗血管瘤疗效观察

血管瘤临床较常见，治疗手段多种，如冷冻、放射、手术及硬化剂注射等，但疗效均不甚满意。作者自1984年11月至1986年5月，用氩激光治疗血管瘤51例，随访6月至2年，疗效尚可。现报导如下：     

氦氖激光临床治疗322例观察

我室从1979年8月至1980年2月共治疗各类疾病322人，其中男172人，女150人。年龄最大76岁，最小半岁。疗程最长20次，最短3次。     

皮肤放射性损伤与氦氖激光治疗附23例报告

我们从1980年到1981年4月，对恶性肿瘤经放射治疗所引起的皮肤放射损伤，用氦氖激光治疗，资料完整的有23例。     

激光与皮肤病

在这篇综述中，作者首先指出激光技术引进皮肤科领域的重要意义，然后就以下七方面进行叙述；一、皮肤病学方面常用激光器的种类，二、激光对皮肤的生物效应；三、激光对皮肤生物化学方面的影响；四、激光在皮肤病学研究方面的应用，五、激光的治疗方式；六、我国激光治疗皮肤病概况，七、激光的安全防护。     

准分子激光在心血管外科的应用

美国航天管理局（NASA）研究人员与洛杉矶三位医生共同研制了一种特殊的激光装置，它将使冠状动脉分流术变得过时。这种装置完成后将可使医生不用手术也不伤及血管壁而清除阻塞了的动脉。     

再多一次接触:顾客反馈机制对服务失败后顾客评价的影响

It is difficult to control service quality for any service firm and service failure is inevitable due to human or non-human factors. As a result, service recovery stirred the interest of researchers and practitioners. However, service failure may not be identified by firms because a majority of dissatisfied customers will not complain to the service provider. Thus, this research proposes a proactive customer feedback mechanism comprised of proactive solicitation of customer feedback, customers providing feedback and follow-up communication and examine their impact of customer evaluations in the context of service failure. This research tries to establish that through adding a continuous series of satisfied service encounters or "moment of truth" to service failure encounters, the customer evaluations (e.g. satisfaction, trust, purchase intent and positive WOM) toward the service will be significantly improved. Our research employed a 2×2×2 between subjects experimental design. Three independent variables were manipulated as presence and absence level, that is, firms either proactively solicitted customer feedback or employed no solicitation of feedback, Customers either provided feedback to the service firm or refused to provide feedback, and service firm either conducted follow-up communication or no follow-up communication. Our research adoptted a scenario in the context of patronizing a three-star hotel on a business trip. In total, 221 business administration graduates from a famous university in Shanghai participated in the experiment. MANOVA was used to test the hypotheses. The results indicated that proactive solicitation significantly influenced trust (p<0.01). Besides satisfaction, the other dependent variables such as trust, purchase intent and positive WOM significantly differred between with and without follow-up communication groups (p<0.05). Third, a significant difference was detected regarding satisfaction, trust, purchase intent and positive WOM between customer providing feedback groups and no customer feedback groups (p<0.05). Moreover, significant interactive effects were found of customers provided feedback and follow-up communication on trust and purchase intent. Trust and purchase intent reached highest when a follow-up communication occurred after customers provided feedback. However, no interactive effects were found of proactive solicitation of customer feedback and customer providing feedback. This research suggests that service providers should create new encounters with customers when they are confronted with service failure, and in this study, through proactive customer feedback mechanism. That is, first, the service provider should encourage customers to provide feedback, which can improve customer evaluations after service failure and after customers providing feedback. At the same time, the firm should employ follow-up communication with the customer and inform them about how the firm responded to their complaints, suggestions and comments. It is worth to note that companies just need to have follow-up communication with those customers who have provided feedback. More important, as information technology and internet prevails, it is very likely sending email and short messages after a service failure to maintain customer relationships could significantly enhance customer evaluations of the service provider. Of course, how consumers respond to such measures online is an promising research area and needs further investigation.     

哈佛大学皮肤科专家研究铜蒸汽激光器

哈佛大学医学院皮肤系的一组研究者正在探索铜蒸汽激光器对人体皮肤的作用。这一工作是该组对激光治疗进行专门研究后的扩展。他们想确定那些能用专门激光器治疗的特定组织结构或疾病。在治疗几种皮肤病方面，看来铜蒸汽激光器可供选择。     

氦-氖激光穴位照射治疗荨麻疹之疗效观察

我们予1978年开始应用低功率氦-氖激光穴位照射治疗44例慢性荨麻疹，其中男性27倒，女性17例。年龄为14岁至52岁。因寒冷发病者8例，慢性咽喉炎者12例，月经前后发病或加重者2例、余者为原因不明者。对照组20例应用穴位针刺疗法，其中困寒冷因素者6例、慢性咽喉炎者2例、人工划痕阳性者3例，余者为原因不明。
