全身热疗法治疗晚期肝脏恶性肿瘤39例报告

目的 探讨全身热疗法（whole body hyperthermia，WBH）治疗肝脏恶性肿瘤的疗效及其对肝功能的影响。方法 采用WBH治疗肝脏恶性肿瘤患者39例，并对治疗前、后患者肝功能指标进行动态观察，分析该疗法对肝脏功能的影响，并通过分析治疗效果，初步评估该疗法的疗效。结果 ①WBH治疗不能手术切除的晚期肝脏恶性肿瘤患者的有效率为61．5％（24／39），60．0％（9／15）的患者AFP有不同程度下降，肿瘤疼痛缓解率达100％；存活期〉2年者占12．8％（5／39），〉1年者占59．0％（23／39），〉6个月者占76．9％（30／39）。②谷丙转氨酶于治疗后1～3d出现明显升高（P〈0．05），7d后下降并接近治疗前水平；谷草转氨酶于治疗后1d明显升高（P〈0．05），3～7d则下降并接近治疗前水平；白蛋白于治疗后1d出现下降（P〈0．05），但3d即已恢复；肝功能正常组总胆红素于治疗后第1～3d出现升高（P〈0．05），而肝功能异常组未观察到同样变化；转肽酶则无明显变化。结论 WBH能改善晚期肝脏恶性肿瘤患者的预后，提高生存质量，延长生存时间，但同时可造成患者肝功能一定程度的可逆性损害。     

涉外护理专业学生社区毕业实习效果评价

目的 探讨涉外护理专业学生社区毕业实习模式。方法 随机设定实验组(36人),参加慢性疾病调查、建立健康档案和进行相应的健康教育,结束时与不参加社区毕业实习的对照Ⅰ组(31人)、对照Ⅱ组(38人)的实习生同时接受基础知识和能力闭卷测试。然后统计调查问卷和健康档案的正确率,并将三组测试成绩进行比较。结果 实验组调查问卷和健康档案的正确率≥95％。实习生基础知识得分实验组(43.14±2.78)、对照Ⅱ组(42.53±1.96)与对照Ⅰ组(40.65±2.47)比较;能力得分实验组(47.00±2.34)与对照Ⅰ组(41.61±3.41)、对照Ⅱ组(41.42±3.52)比较;总分实验组(90.14±4.30)与对照Ⅰ组(82.26±5.33)、对照Ⅱ组(83.95±4.13)比较,均P<0.01,差异有极显著性意义。结论 社区毕业实习强化了实习生社区护理的基本知识,培养了实习生社区护理的相关能力。但有待于规范化。

本系统的107个电极中,103个分布于胸、背部,1个为参考电极,1个为V_3,其余用于肢导。本系统除能绘出2、4、8ms任意间隔的103通道同步的体表等电位图,常规12导联和V_(7 9)心电图,胸、背部位的心电图外,还可记录R峰值等电位图,∑R,Q波等电位图,nQ30、40,极大、极小轨迹图等。     

螨类接种豚鼠气管引起的肺部病变

本文首次报导了螨类接种豚鼠气管所引起的肺部病变。螨类接种后的第6天发现肺部已形成典型的结节性病灶。结节呈圆锥形,淡黄色,直径1～5mm之间。镜下主要表现为细支气管和细支气管周围的病变。和早年报导的猴肺螨病肺部病变比较,有以下不同,肺实质内有明显的异物肉芽肿形成,炎症反应中嗜酸性细胞浸润不明显,而有更多的异物巨细胞形成;细支气管周围的小动脉受到损害:部分小动脉壁平滑肌明显增厚,以致腔隙变窄,部分小动脉腔内可见到虫体。根据我们实验研究证明,螨类接种豚鼠气管可引起肺部的典型病变.因而认为用豚鼠作为肺螨病的动物模型是有希望的。     

广西壮、汉族体重指数与血压、血脂、脂肪肝等相关因素的关系

目的：探讨广西地区人群体重指数（BMI）与血压、血糖、血脂、脂肪肝、心电图异常、性别、民族及其他心脑血管病史等因素的相关性，并比较这些因素在壮族与汉族人群中的差异。方法：对在本院及田阳县、田东县参加体检的1105例壮族与汉族人群询问病史并检查身高、体重、血压、空腹血糖、血脂、肝脏B超、心电图等。结果：在按制其他因素后，汉族人群BMI与脂肪肝、舒张压水平及高血压病史呈密切正相关关系，男性BMI高于女性；壮族人群BMI与脂肪肝、血清甘油三酯浓度及收缩压水平有密切正相关关系，汉族人群的年龄、BMI、血清甘油三酯浓度、胆固醇浓度、收缩压水平、脂肪肝检出率及心电图异常检出率均较壮族人群高。结论：肥胖与脂肪肝、血压、血脂密切相关，且广西汉族人群肥胖、脂肪肝、高血脂、高血压及心电图异常较壮族人群更常见。     

Symptoms of contruction workers exposed to whole body vibration and local vibration

Summary To study the effects of construction machinery operation on subjective symptoms, a questionnaire survey was caried out among construction machinery operators by a self-reporting method. Subjects were 184 power shovel operators, 127 bulldozer operators, 44 forklift operators as operator groups, and 44 office workers as a control. Their ages were in a range of 30–49 years. The questionnaire contained 20 symptoms referring to fatigue, digestive problems, and upper or lower limbs or back problems. The prevalence rate and symptom characteristics were examined. The dominant symptoms of the operator groups were stiff shoulder, low back pain, and stomack symptoms. The prevalence rate of low back pain was significantly different between forklift operators and controls. No significant differences were found in the symptoms of upper limbs and fingers between operator groups and controls. The prevalence of Raynaud's phenomenon was 0.5%–2.3% in the operator groups and 2.3% in the control group.     

Thoracoscopic Retrieval of Foreign Bodies After Penetrating Chest Trauma

Video-assisted thoracic surgery or thoracoscopy has proved to be valuable in many settings in thoracic surgery. The use of video-assisted thoracic surgery in trauma has been limited, especially with respect to penetrating trauma. We report the use of thoracoscopy to remove intrathoracic fragments of glass and avert the need for a thoracotomy.     

Voluntary head stabilization in space during oscillatory trunk movements in the frontal plane performed in weightlessness

 The ability voluntarily to stabilize the head in space during lateral rhythmic oscillations (0.59±0.09 Hz) of the trunk has been investigated during microgravity (μG) and normal gravity (nG) conditions (parabolic flights). Five healthy young subjects, who gave informed consent, were examined. The movements were performed with eyes open or eyes closed, during phases of either μG or nG. The main result was that head orientation with respect to vertical may be stabilized about the roll axis under μG with, as well as without vision, despite the reduction in vestibular afferent and muscle proprioceptive inputs. Moreover, the absence of head stabilization about the yaw axis confirms that the degrees of freedom of the neck can be independently controlled, as was previously reported. These results seem to indicate that voluntary head stabilization does not depend crucially upon static vestibular afferents. Head stabilization in space may in fact be organized on the basis of either dynamic vestibular afferents or a short-term memorized postural body schema.
