AFAM+:果蔬长途冷藏运输新技术
19世纪末,植物生理学家就已经意识到,减少果蔬周围空气中的O2浓度能减缓果实的新陈代谢速度.随后,美国、日本、加拿大等国家陆续开展了对果蔬气调贮藏的研究.

对妇科腹腔镜手术后恶心呕吐与麻醉方法的简述
随着工业制造的迅速发展,相关学科的融合为开展新技术和新方法奠定了尤为鉴定的基础,加之临床医生手术操作的娴熟,使得许多开放性手术被腔内手术取代,这大大增加了患者为手术选择的机会。腹腔手术作为近年来新发展起来的微创手术方法,在妇科外科手术中已得到十分广泛的应用。本文通过对相关临床资料进行分析,对妇科腹腔镜手术后恶心呕吐与麻醉方法的选择做一综述。

中国微创全髋人工关节置换术的现状和将来
微创是外科各大领域在21世纪寻求突破的新技术,是医患双方的共同追求目标。微创全髋人工关节置换术在骨科领域同样引起了广大的关注,是关节外科当今研究的热点问题。国内众多的医院已采用微创的方式进行人工髋关节置换,但报道不尽相同。本文回顾了微创全髋人工关节置换术目前在我国发展的情况,着重归纳了微创全髋人工关节置换术的适应证、手术入路以及其优缺点,以便于将该项技术更广泛地推广应用。

空间声源定位研究和助听器新技术
1声音解析人类的听觉系统能主动运用潜意识去捕捉周围的各种声音,并转变成自身需要的有意义的信息.虽然人们的听觉、视觉、嗅觉和本体感觉系统时刻接收到各种信号,但是人们只会关注那些被认为有意义的事物.按照格式塔组织原则,人类这种极其重要的组织和分析功能可避免自己陷入太多无意义信息的漩涡中.

重视提高肩肘关节镜新技术的研发与应用
我国肩肘关节镜技术于20世纪90年代初刚刚起步,经过几代人的辛勤努力,手术数量逐年递增,相关的研究步步深入,取得了长足的发展.肩肘关节镜事业的发展还不平衡,很多医院虽然已经有了相应的设备,但至今尚未开展相关业务,从业队伍的技术水平有待于进一步提高.因此,加强肩肘关节镜微创外科的临床与基础研究,追赶国际先进水平,不容忽视.

彩色室壁运动显像评价冠心病患者康复训练后心功能的研究
Background: Ultrasound cardiogram plays an important role in evaluating cardiac function of patients with coronary heart disease before and after rehabilitation.Wall motion,function of contraction,and cardiac function could be evaluated using ultrasound cardiogram.Sensitivity of visual method in evaluating wall motion is not high.Color kinesis(CK) is a kind of new technology.Objective: To study sensitivity and accuracy of CK and visual method in evaluating wall motion.Design: In order to test sensitivity of CK,we compared CK and visual method.Unit: General Hospital of Shenyang Military Region Subjects:120 patients suffered from coronary heart disease during 1998~ 2000,78 male,42 female,aged from 36~ 72 years(mean:54 years).All patients had history of precardial pain,and ST-T changes were found in ECGs.Intervention: Coronary arteriography was done on all patients.To observe wall motion using visual method and CK.Color Doppler inspector HP2500 with a probe(2.5MHz/2.0MHz).Patients lied in horizional position.Then CK examination was done after defining endocardium.Simularly,electrographic signals were recorded.Endocardial motion were numbered colorfully.

超声造影新技术对肝肿瘤非手术治疗后的评价作用
肝癌的非手术治疗多为肝动脉栓塞化疗(TAE)和超声引导下的瘤内无水酒精注射、射频消融、微波热凝固等的综合治疗,疗效的判断则多从l临床症状改善、免疫指标恢复正常、肿块缩小等来评价.然而,这些指标常需在治疗一段时间后才能反映结果,不能实时引导对残存肿瘤的及时追加治疗.由于局部治疗多在实时超声的引导下进行,而常规超声对显示局部治疗后的有效范围有一定局限性[1].因此,在声像图上识别肿瘤的残存区域十分重要.

Progress on renal sympathetic nerve ablation for refractory hypertension
Hypertension is a chronic cardiovascular disease worldwide.Its association with major adverse cardiac and cerebral events and favorable effects of antihypertensive therapy are ndisputed.It has been estimated that the total number of patients are more than one billion people[1].In recent years, the drug reatment of hypertension has made great progress, especially for a large number of long-acting antihypertensive drugs and the application of the new compound preparation so that the control rate of hypertension significantly increased.However, hypertensive patients received diuretics, including more than three high-dose antihypertensive drug treatment, but has not yet reached the target blood pressure, clinically known as refractory hypertension (treatment resistant hypertension) about the total number of patients with 20% to 30% [2], and such patients have a higher incidence of adverse cardiovascular events[3].efractory hypertension is not only caused by many reasons, but also illustrates the limitations of the medication.Therefore, people began to say, non-drug treatment of hypertension.Most recently, attention has been redirected to the sympathetic nervous system in the pathogenesis of hypertension.In addition, interruption of the renal sympathetic nervous system in humans with resistant hypertension has been studied with promising results.In 2009, Monash University, Australia Krum professor′s first report of renal sympathetic nerve ablation(Renal sympathetic denervation) was used in the treatment of resistant hypertension, creating a non-drug treatment of essential hypertension in new ways.In this review, a brief introduction mentioned the research progress of this new technology.

Overview of new technologies and trends in sterilization and disinfection
Introduction Each year in US,approximately 101 million medical procedures are performed including about 10.8 million gastrointestinal endoscopies and round 440 000 bronchoscopies[1].All invasive procedures involve contact by a medical device or surgical instrument with a patient's sterile tissue or mucous membranes.
