抗肝癌单链双功能抗体在Hut-78细胞系中的表达及体外杀伤活性

目的 用携带分泌型抗肝癌单链双功能抗体基因（sFv-TNF-α）的重组逆转录病毒感染T细胞淋巴瘤Hut-78细胞，使其表达并分泌针对人肝癌细胞的sFv-TNF-α融合蛋白，观察转导的T细胞对体外培养肝癌细胞的杀伤作用。方法 用感染性重组病毒产生细胞C22（PA317/PST）产生的病毒上清转导入T细胞淋巴瘤Hut-78细胞，采用PCR，RT-PCR，细胞原位杂交及免疫组织化学染色等方法，对转导的Hut-78细胞进行DNA，mRNA及蛋白水平的分析。转导的Hut-78细胞分别与SMMC-7721，HHCC共培养，MTT法检测Hut/PST细胞表达产物对两种肝癌细胞的杀伤作用。结果 PCR，RT-PCR结果显示转导Hut细胞中扩增出外源目的基因对应的电泳条带，neo基因探针原位杂交显示转导细胞质内有较强的紫蓝色阳性反应信号，其阳性率约为95%，鼠抗人TNF-α多克隆抗体免疫组织化学染色，转导细胞质内有明确的棕黄色阳性反应信号，MTT法检测结果，分泌型抗肝癌单链双功能抗体对体外培养的两种肝癌细胞的杀伤率分别为15.4%和26.5%。结论 分泌型抗肝癌单链双功能抗体基因可以在T细胞中整合并稳定表达，其分泌的表达产物对两种肝癌细胞均具有一定的亲合活性，并且具有一定的体外杀伤作用。     

颅脑损伤患者的运动处方

颅脑损伤后的运动疗法是该损伤综合康复治疗方法的重要一环，对胶体运动障碍，疗效确切。是促使患早日康复，尽快恢复运动功能最有效的方法之一。康复期不同阶段所实施的运动种类不同、方法不一，运动强度因人而易。     

Effect comparison between sacral blocking and massage combined with traction on protrusion of lumbar intervertebral disc

Background:Epidural injection is an important method in treatment of protrusion of lumbar intervertebral disc.Especially in the recent decade sacral injection is adopted more and more often.Objective:To compare the clinical effects of sacral blocking and massage combined with traction.Unit:Yinhe Hospital of Beijing.Subjects:290 outpatients with grade Ⅱ of ASAI were selected from May,1994 to July,2000.Patients were randomly divided into observation group(n=145)and control group(n=145).Sacral blocking was adopted in observation group and 80 males and 65 females aged 20-78(mean:46.4)years old were included with disease course 3 days to 30 years.Massage combined with treaction was adopted in control group and 74 males and 71 females aged 22-74(mean:44.9)years oled were inmcluded with disease course 2 days to 10 years.Interention:Sacral blocking:Operation was according to sacral blocking and druge(dexamethasone injection,2 mg;0.75% bupivavaine hydrochloride,5 ml;saline,50ml) were injected slowly after success of puncture.Patient rested for 0.5h after injection and left treatment room if no adverse effects occurred.Massage combined with traction:Massage was adopted after traction to every patients.(1)Massage:Patient was seated at square stool and lower limbs separated naturally with same width of shoulders.Doctors sit behind patient.First,thubs of both hands were pressed on projecting part near spinous process(pressing points were selected according to different projecting part).Flexing and extending forward and backward were taken at the same time and extent was ddecided addording to patients‘ maximal endurable degree,5-10 timmes.Upper part of body was turned 45 degrees to left and right.Massage was still taken to affected part,3-t times.(2)Traction:Pelvis was extracted with general physical therapy and massage table.Supine position,chest and treaction bandage were fixed,tractiron wheel was turned slowly until patient felt comfortable with maximal endurance as limit(traction force,20-40kg),After extracting for 5 minutes,massagee switch was turned on to take rolling massage to bck and both lower libmbs.Traction force was increased every5 minutes and limit was still according to patient‘s maximal endurance,30 minutes for every time,once a day and ten times as a therapeutic course.Cohclusion:Effect of sacral blocking on protrusion of lumbar intervertebral disc was positive and fewer therapeutic time were needed.Massage combined with traction was also effective,safe and no adverse effects wer observed,but more therapeutic times were neeeded and inconveinient.     

整合素与头颈部肿瘤

恶性肿瘤浸润主要包括细胞粘附，基质分解和细胞转移三个步骤。粘附分子在这些过程中起重要作用。整合素是粘附分子中重要的一类，它介导细胞与细胞外基质（ECM）、细胞与细胞间的粘附。在头颈部肿瘤中其分布和表达异常，并参与癌细胞的浸润与转移。整合素与细胞的凋亡也有关。胞外环境可影响整合素的结合，一些细胞因子和二价阳离子可调节整合素的表达，影响细胞粘附。整合素与头颈部肿瘤的发生，发展密切相关，故上述与整合素相关的调节因素正成为头颈部肿瘤治疗研究的新方向。     

前列腺肥大警惕尿毒症

俗话说：“少年撤尿射过墙，老年小便湿裤裆。”上了年纪的男性，不少会遇到“小便湿裤裆”的尴尬，导致这种情况发生的常见原因，就是前列腺增生肥大。而作为中老年男性的常见病，如果前列腺增生肥大长时间得不到治疗，甚至可导致慢性肾功能不全。[第一段]     

猪皮冻与保健美容

不少人食用猪肉时，往往将猪皮扔掉。其实，猪皮是一种对心脑血管有利无弊的一种佳肴。《中华本草》载：猪皮含有蛋白质、脂肪及硫酸皮肤素B，具有软化血管、抗凝血，促进造血功能和皮肤损伤愈合及保健美容作用，其胶质的造血功能优于阿胶，常食可增加血红素含量及白细胞数的增加和抗血栓的形成。[第一段]     

年轻宫颈癌患者保留生理功能的可行性

随着医疗技术的不断进步，肿瘤治疗手段越来越多，肿瘤患者的生存率也不断提高，人们越来越多的关注肿瘤患者的生理功能。在治疗各种肿瘤患者时，提高生活质量已经成为决定治疗方法的重要依据之一。宫颈癌是女性常见恶性肿瘤，尤其近年来发病率逐渐增加，并呈年轻化趋势。对宫颈癌患者保留生育功能已经成为目前的热点问题。本文结合国内外报道，对早期宫颈癌患者保留生理功能的治疗进行论述。     

慢性肠炎的药膳方

慢性肠炎的病因主要有，急性肠炎反复不愈转成慢性，二是精神因素影响到迷走神经的功能紊乱，三是肠道狭窄或有息肉，有溃疡或癌肿。表现各不相同，一般为腹泻、里急后重，胀气、肠鸣等。慢性肠炎的药物治疗效果只得一时，欲巩固须注意日常的调理，尤其是饮食方面的调理，包括供给充足的营养，易消化，限制机械性刺激，保护肠道功能。
