提高《物理诊断学》教学质量的探索与实践

总结了物理诊断学的基本特点和教授本课程时需把握好的几个环节 ,就提高物理诊断学教学质量进行了一些思考 ,并结合我院经验提出了物理诊断学教学改革的创新思路     

冠心病患者血清同型半胱氨酸与叶酸、维生素B12水平的变化

目的 探讨冠心病患者血清同型半胱氨酸(HCY)与叶酸、维生素B12浓度的变化及其相关性。方法 选择84例经冠状动脉造影术证实为冠心病的患者，应用荧光偏振免疫分析法(FPIA)测定血清HCY浓度，离子捕获免疫分析法(ICIA)测定血清叶酸浓度，非均相微粒子酶免疫分析法（MEIA)测定血清维生素B12浓度。结果 冠心病患者血清HCY浓度增高，与正常对照组比较有显著性意义(P＜0．001)，而叶酸、维生素B12浓度则降低，与正常对照组比较有显著性意义(P＜0．001)，以上两种变化呈负相关(P＜0．001)。结论 同型半胱氨酸血症是冠心病的新的独立危险因素，叶酸、维生素B12缺乏可能是诱发高HCY的重要因素。     

Dislocation of an upper third molar into the maxillary sinus after a severe trauma: a case report

Abstract – Dental injuries are common following facial trauma. This article presents a rare injury: the dislocation of a third molar into the maxillary sinus after complex mandibular and maxillary tuberosity fractures. The possible mechanism and clinical treatment are discussed.     

照射与免疫的时间间隔对抗体形成的影响及其辐射剂量效应

本实验观察了0. 25、0. 5、1. 0、2. 0、3. 0和4. 0Gy全身照射后3至6 h羊红细胞(SRBC)免疫对小鼠脾脏抗体形成细胞(PFC)的影响。结果发现,各剂量照射后,免疫与照射的时间间隔较长者,辐射对PFC反应的抑制显著加深。照射后3及6h免疫,脾脏PFC反应均随照射剂量的增加而降低。照射后3h免疫时,PFC反应的D_(37)值为4. 13Gy;照射后6h免疫时,PFC反应的D_(37)值为1. 74Gy。     

THE CAIMA SYSTEM

CAIMA is the abbreviation of Computer-Assisted Instant Monitoring drug Administration. CAIMA works on the principle of closed-loop negative feedback. Special programs have been designed to meet the needs of: a) Patients' safety, b) Response level desired, c) Output necessary for actuating the injecting pump. The pump forces the drug solution to enter the body with high precision. The author shows 8-year experience of using CAIMA system in laboratory and in hospital operating rooms. Experimental studies revealed that: CAIMA system attenuates the overshots and undershots usually present in reaction to drug administration, thus saves the drug and thereby causes less side-efiffeets, while the recovery is also much shortened. CAIMA system provides a greater tolerance to extra-stimuli and preserves the body original reactive sensitivity to drug. The homeostasis in animals is better kept with CAIMA than without. Clinically, the arbitrary hypotension during brain surgery with sodium nitroprusside and the control of muscle relaxation in general surgery with muscle relaxants have been successful using CAIMA system.     

腺病毒载体介导CTLA4Ig基因治疗小鼠变应性鼻炎

目的 检测CTLA4Ig-重组腺病毒载体（Ad-CTLA4Ig）在变应性鼻炎治疗中的作用。方法 采用卵清蛋白（OVA）致敏和激发诱导小鼠变应性鼻炎。实验组在OVA激发前30min予以Ad-CTA4Ig腹腔注射。未转CTLA4IgcDNA的腺病毒载体（Adv）作对照。比较各组动物鼻部症状和鼻粘膜形态学改变，并采用ELISA法测定血清中OVA－特异性IgE水平。结果 CTLA4Ig重组腺病毒实验组小鼠鼻部症状和鼻粘膜病理改变不明显，并且血清中OVA－特异性IgE水平明显低于对照组（P＜0.05）。结论 Ad-CTLA4Ig可防治小鼠应变性鼻炎的发生，提示CTLA4Ig-重组腺病毒载体有可能运用于临床变应性鼻炎的治疗。     

温针灸治疗颞下颌关节功能紊乱病36例

目的:比较温针灸与口服西药治疗颞下颌关节功能紊乱病的疗效。方法:治疗组36例取下关、牵正、颊车、阿是穴、合谷(双)行温针灸,对照组口服地西泮、吲哚美辛。结果:治疗组治愈率80·6%、总有效率100%,对照组治愈率40·6%、总有效率78·1%,两组有非常显著性差异(P<0.01)。结论:温针灸治疗颞下颌关节功能紊乱病方法简单,疗效显著。
