GP与MPV方案治疗晚期非小细胞肺癌的疗效比较

目的　比较 GP与 MPV方案治疗晚期非小细胞肺癌 (NSCL C)的疗效。方法　 6 4例晚期 NSCL C患者随机分组 ,采用 GP治疗 32例 ,MPV治疗 32例。 Kaplan- Meier方法分析患者中位生存期 ,比较患者近期有效率及化疗毒副作用。结果　 GP组有效率 5 0 % (16例 ) ,MPV组有效率 2 8% (8例 ) ,两组有效率比较差异具有显著性 (P<0 .0 0 5 )。MPV组中位生存期为 32周 ,GP组中位生存期 5 1周 ,两组生存期差异有显著性 (P<0 .0 0 5 )。化疗的毒副反应主要是胃肠道反应和骨髓抑制。结论　 GP比 MPV更能延长患者中位生存期增加有效率 ,但并没有增加毒副反应     

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。
