多疗程治疗的癌症病人入院时的焦虑状态调查

[目的]了解恶性肿瘤病人反复多次入院治疗时的心理状态,通过护理干预帮助病人更快投入治疗情境.[方法]通过焦虑自评量表(SAS)进行心理测验,随机将病人分为对照组和实验组,针对结果分别进行相应护理,1周后复查.[结果]实验组和对照组护理后的SAS评分差异显著.[结论]癌症病人多疗程入院的病人焦虑状况严重,实施焦虑的支持护理及心理辅助,可较好地促进病人进入治疗角色,减少弃治轻生的发生.     

对药代动力学实验的两点改进

通过具体的实验数据，讨论在药代动力学实验中如何加入曲线下面积（AUC）的计算，以帮助学生理解并掌握这一概念；在实验室设置不同剂量组，给药后比较剂量与浓度是否呈等比例关系，以此加深学生对于一级动力学消除及其临床意义的理解。     

腰椎后路非融合固定系统的临床应用

复习腰椎后路非融合固定系统的设计原理、临床应用及治疗效果等相关文献,与传统的脊柱融合术相比,应用非融合系统可获得很好的疗效,并可以减少邻近节段退变的发生率。     

大鼠大脑中动脉闭塞后丘脑钙调磷酸酶含量与活性的研究

目的 揭示大脑中动脉闭塞(MCAO)后丘脑钙调磷酸酶(CaN)的时空变化规律，探讨CaN的作用机制。方法 制备大鼠大脑中动脉永久性闭塞模型，分别测定缺血后不同时间点病灶侧丘脑CaN的活性和含量。结果 缺血后24h始丘脑CaN的含量下降且不恢复；CaN的活性在缺血后2h和4h减弱，6h始恢复至正常水平。可见，CaN的活性与含量分离。结论 大脑中动脉闭塞后丘脑CaN活性独特的时间变化规律显示其参与介导继发性丘脑损伤，可能具有毒性作用。

Visual acuity results in school-aged children and adults: Lea Symbols chart versus Bailey-Lovie chart.

PURPOSE: To compare visual acuity results obtained using the Lea Symbols chart with visual acuity results obtained with the Bailey-Lovie chart in school-aged children and adults using a within-subjects comparison of monocular acuity results. METHODS: Subjects were 62 individuals between 4.5 and 60 years of age, recruited from patients seen in five optometry clinics. Each subject had acuity of the right eye and the left eye tested with the Lea Symbols chart and the Bailey-Lovie chart, with order of testing varied across subjects. Outcome measures were monocular logarithm of the minimum angle of resolution (logMAR) visual acuity and inter-eye acuity difference in logMAR units for each test. RESULTS: Correlation between acuity results obtained with the two charts was high. There was no difference in absolute inter-eye acuity difference measured with the two acuity charts. However, on average, Lea Symbols acuity scores were one logMAR line better than Bailey-Lovie acuity scores, and this difference increased with worse visual acuity. CONCLUSIONS: The Lea Symbols chart provides a measure of inter-eye difference that is similar to that obtained with the Bailey-Lovie chart. However, the monocular acuity results obtained with the Lea Symbols chart differ from those obtained with the Bailey-Lovie chart, and the difference is dependent on the individual's absolute level of visual acuity.     

无骨折脱位型颈脊髓损伤的治疗

目的:探讨多节段无骨折脱位颈脊髓损伤的治疗。方法:多节段无骨折脱位型颈脊髓损伤21例,均行单开门颈椎管扩大减压成形术。采用JOA、Frankel分级及影像学进行疗效评价。结果:平均随访2年1个月,JOA评分术后改善率为37.81%,Frankel分级A→B 1例,B→C 7例,C→C 1例,C→D 10例,D→D 2例,D→E 4例。影像学检查提示颈椎生理曲度正常,未发现有再关门及不稳定现象。结论:单开门棘突重建颈椎管扩大成形术由于重建了颈后方韧带复合体,对于改善和维持颈椎的生理屈度、稳定性方面有重要的临床意义。     

Klippel-Feil syndrome plus atretic meningocele in one identical twin and anencephaly in the other.

Klippel-Feil syndrome (KFS) is a heterogeneous entity, characterized by specific congenital anomalies of segmentation of the cervical spine. We report a case of KFS plus atretic meningocele in one identical twin and anencephaly in the other. These identical twins were both male with no chromosome defect. One of them had anencephaly diagnosed at the gestational age of 17 weeks and died soon after birth, whereas the co-twin had KFS with multiple congenital anomalies including short neck with low hairline, occipital atretic meningocele, butterfly vertebrae, hemivertebrae, cervico-thoracic scoliosis, left thumb preaxial polydactyly, and right undescended testis. He received rehabilitation during infancy and could walk at the age of 15 months. Both of these infants had preaxial polydactyly, which is an uncommon anomaly associated with KFS. In conclusion, iniencephaly and anencephaly are probably the extreme manifestations of KFS rather than different dysraphisms. Prompt clinical suspicion with early diagnostic imaging for spine lesions and occult opening of neural tube is mandatory for further intervention and rehabilitation.
