脑出血继发损伤中沉默信息调节因子2的表达和炎症反应*

目的：探讨脑出血对酵母沉默信息调节因子2（Sirt2）和炎症的影响。方法：将胶原酶Ⅳ注入SD大鼠右侧 纹状体中建立脑出血模型，通过免疫印迹和ELISA 等方法测定大鼠脑出血后48 h 的Sirt2 的表达及炎症变化。利 用Hemin 诱导PC12 细胞损伤模拟体外脑出血模型，并检测Sirt2 及炎症变化；采用短发夹RNA（shRNA）-Sirt2 沉 默Sirt2 在PC12 细胞中的表达及对炎症的影响。结果：手术后48 h 脑出血行为学评分最低。脑出血组Sirt2 的表达 显著高于假手术组。脑出血组IL-6、IL-1β 表达显著升高。结论：脑出血可以促进Sirt2 的表达和炎症反应，降低 Sirt2 的表达可减缓炎症反应。 关键词 脑出血；沉默信息调节     

疑似新型冠状病毒肺炎患者鼻咽拭子标本采集流程的改进

针对疑似新型冠状病毒肺炎患者行鼻咽拭子标本采集中存在的职业暴露风险，成立专项督导管理小组，在遵照各项防控规范执行标准防护的基础上，贴近临床，细化操作环节，制定操作流程指引，实施集中模拟情景培训演练与考核。降低操作者职业暴露风险的同时，又保证采集者的操作同质化。共成功采集鼻咽拭子1 649例，医务人员零感染。

浅谈乳腺叶状囊肉瘤与乳腺纤维腺瘤超声影像的相关性及临床意义

乳腺纤维腺瘤发病率在乳腺良性肿瘤中居首位,而乳腺叶状囊肉瘤在临床恶性病变中也并不罕见,有的学者报道与乳腺癌之比可达1∶20.国内有些学者认为,叶状囊肉瘤虽然可以由纤维腺瘤经肉瘤变而成,但是也可能开始时就是肉瘤.本文通过对32例经手术病理证实的病例进行回顾分析,以探讨二者超声影像的相关性及临床意义.     

改良式腭托矫治双尖牙正锁12例

双尖牙正锁牙合是一种常见的错牙合畸形。后牙正锁牙合影响下颌侧向运动,引起颜面不对称畸形,诱发颞颌关节疾病,应尽早矫治。我们在口腔正畸治疗中,创新出一种改良式腭托,临床使用效果满意,现介绍如下。临床资料1病例选择:本组共12例,其中男5例,女7例。年龄12~28岁,平均17.5岁。选择标准:上颌双尖牙区牙弓过宽,双尖牙颊向倾斜或移位,锁牙合区有散隙,且每例中锁牙合牙数不少于2个。2矫治器制作:选用1.2mm直径的不锈钢圆丝弯制腭杠及腭托连接体部,与后牙带环舌面银焊;双股0.5mm直径的不锈钢圆丝弯制牵引钩,根据锁牙合牙位埋入腭托即可。3治疗…     

磁共振血管成像技术与高压注射器匹配的应用探讨

目的 探讨磁共振血管成像技术与高压注射器应用的匹配问题.方法 本组68例,年龄36岁-85岁,平均60岁,其中男53例,女15例.使用德国西门子1.0T超导磁共振成像仪及德国Ulich高压注射器和北陆的造影剂GD-DTPA静脉团注.结果 动脉显影良好64例(94%),3例患者血管显影欠佳(4.4%),1例患者出现药液渗漏失败(1.4%),所有检查病人均无出现不适.结论 正确熟练掌握高压注射器,使3D-CE-MRA成像扫描时间和团注速度相匹配,是获得高质量图像的重要环节,也是3D MRA检查成功的关键之一.     

生活方式干预对食管癌二级预防的应用

目的:通过对食管癌的患者不良生活方式进行干预,探讨对食管癌二级预防的效果。方法:选取住院患者87例,入院时、住院时和出院后共进行为期6个月的生活方式干预,观察干预前后的情况。结果:干预后患者情绪波动、高脂饮食、吸烟、饮酒、不良生活习惯下降,健康饮食、遵医嘱用药的行为上升。结论:生活方式的干预可促进患者建立健康的生活习惯,有利于食管癌的二级预防。     

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.
