消瘀接骨散联合常规疗法对类风湿关节炎患者生活质量及Act1/NF-κB/IκBα的影响

目的观察消瘀接骨散联合常规疗法对类风湿关节炎(RA)患者生活质量及核因子κB(NF-κB)通路相关因子的影响。方法将60例RA患者随机分为对照组和研究组,每组30例。对照组采用基础治疗,研究组采用基础治疗联合消瘀接骨散外敷治疗。4周后观察两组临床疗效、关节症状(关节疼痛、肿胀、压痛和晨僵)、生活质量评分(生理、心理、社会和健康功能)、实验室指标[类风湿因子(RF)、C反应蛋白(CRP)、血沉(ESR)]、血清细胞因子[白细胞介素(IL)-4、IL-12、IL-17、NF-κB]、NF-κB通路相关指标[NF-κB激活剂1(Act1)、NF-κB抑制蛋白α(IκBα)、NF-κB]的变化。结果治疗后,研究组显效率[60.00%(18/30)]明显高于对照组[33.33%(10/30),P0.05]。与本组治疗前比较,研究组关节疼痛、肿胀、晨僵、生理、社会功能评分降低,且NF-κB、Act1 mRNA表达降低(P0.05,P0.01)。与对照组治疗后比较,研究组治疗后关节肿胀、晨僵评分、NF-κB表达降低(P0.05)。结论消瘀接骨散通过抑制NF-κB通路过度活化,下调炎性细胞因子IL-17表达,改善关节功能和生活质量。     

普通话水平测试在医学生中的促进作用

1994年10月30日，国家语言文字工作委员会、国家教育委员会、广播电影电视部联合发布《关于开展普通话水平测试工作的决定》，从此全国范围的普通话水平测试工作正式启动，也标志着我国普及国家通用语言的工作进入一个新的历史阶段。几年来，随着改革开放的进程不断加快，普通话的推广越来越受到重视，语言文字工作取得了可喜的进展。     

复方银杏叶片对阴虚血瘀模型大鼠血液流变性的影响

用氢化可的松、肾上腺素复制阴虚血瘀模型大鼠，观察复方银杏叶片对模型大鼠血液流变性异常的影响。结果表明，该药能够降低模型大鼠的全血粘度、血浆粘度、红细胞压积沉降，提示复方银杏叶片具有改善血液流变性，调节微循环的作用。     

氯丙嗪导致剥脱性皮炎1例报告

剥脱性皮炎是抗精神病药物氯丙嗪所致最为严重的并发症之一[1-2],为一种全身性弥漫性暗红斑磷屑性皮肤病。病变部位潮红、肿胀,可有渗液,重者批发、头发、指甲均可脱落,是药疹中最重型。     

麻风菌基因分型及流行病学应用的研究

虽然麻风病在全世界不再是一个公共卫生问题，但是在一些国家和地区，麻风病的发现率仍旧没有明显下降。既往认为，麻风菌不能体外培养，缺乏对麻风菌的深入了解。基因组测序的成功，为麻风菌的分型提供依据。迄今为止，VNTR和SNP是麻风菌分型的基础，VNTR是由于核苷酸在复制过程中的滑动链错配引起，麻风菌的基因分型和麻风菌的地理分布和历史变迁有一定的关系，其中以VNTR为基础的地理分型和麻风病的短传播链有关，而且对于复发和再感染的鉴别具有积极意义。并探讨VNTR稳定性的意义。     

胰岛素强化治疗对严重创伤患者炎性反应及预后的影响

Objective To investigate the effects of intensive insulin therapy on inflammatory re-sponse and prognosis of patients with severe trauma. Methods Eighty severely injured patients were di-vided into intensive insulin therapy group (n = 40, IT) and routine therapy group (n = 40, RT) in random pair. At the time of admission, a continuous infusion of insulin (2 -4 U/h) was pumped into the patients of IT group to maintain blood glucose level at 6 -8 mmol/L. Patients in RT group were given routine treatment without administration of insulin. Fever, organ injury, and mortality of patients in 2 groups were recorded. Venous blood was drawn from patients of 2 groups on the morning of post treatment day (PTD) 1, 3, 5, and 7. Values of TNF-α, C-reactive protein (CRP), IL-2, and IL-10 in plasma were assayed. Results High fever appeared in 9 patients in IT group, and WBC exceeded 10.0×109 for more than 3 days in 17 patients in this group, versus 20 and 29 patients respectively in RT group. Dysfunction of 1 organ appeared in 31 pa-tients in IT group and 30 patients in RT group. Dysfunction of 3 organs appeared in 10 patients in IT group and 19 patients in RT group. Dysfunction of 4 organs appeared in 7 patients in IT group and 12 patients in RT group. In IT group, 4 patients died within 3 post-injury day (PID), and 1 patient died after PID 3 (total case fatality: 12.5% ). In RT group, 5 patients died within 3 PID, and 4 patient died after PID 3 (total case fatality: 22.5%). Plasma levels of TNF-α and CRP of patients in IT group were significantly lower than those of patients in RT group on PID 3 - 7 ( P<0.05 or P<0.01 ), while levels of IL-2 and IL-10 of patients in IT group were significantly higher than those of patients in RT group ( P<0.05 or P<0.01 ). Plasma levels of TNF-α ( 1.3±0.6 μg/L) and CRP (55±16 mg/L) of patients in IT group on PTD 7 were lowered to the trough level, and they were significantly lower than those of patients in RT group (3.0±0.8μg/L, 89±20 mg/L, respectively, P <0.01 ). Conclusions Intensive insulin therapy can mitigate systemic inflammatory response and improve prognosis of patients with severe trauma.     

静脉滴注钾盐溶液的护理

临床上，应用静脉滴注钾盐溶液进行治疗是相当普遍的。因为钾离子在体内的生理功能及代谢均有其特殊性，所以在滴注钾盐时，除必须遵守静脉输液的一般护理规程外，尚有一些特殊要求。     

小鼠经口投镉的慢性毒性研究——病理形态学改变的探讨

选用昆明种小鼠60只,体重18～24克,随机分成三组,每组20只,雌雄各半。通过饮水染毒。一组正常对照,饮自来水,二组饮30ppm含镉水,三组饮300ppm含镉水,染毒时间三个半月。观察指标:体重增长速度、脏器系数、肝肾中镉含量、重点病理形态学改变(光镜和电镜)。结果,30ppm组小鼠肝肾组织有一定病变,300ppm组小鼠的光镜和电镜的病理形态学改变更为明显。提示,小鼠长期摄入镉可引起一定的损害。
