超声造影时间-强度曲线与伽马拟合曲线对肝细胞癌的诊断价值

目的 探讨联合时间-强度曲线与伽马拟合曲线评估肝细胞癌的超声造影增强模式及其诊断意义.方法 回顾性分析34例经手术病理证实的肝细胞癌患者的超声造影图像,绘制时间-强度曲线,并在此基础上行伽马拟合曲线分析,得出各项定量参数:始增时间、上升支斜率参数、曲线尖度、拟合系数、达峰时间、达峰强度、达峰前平均强度、上升支斜率、达峰前面积.结果 与周边肝实质区相比,肿瘤区曲线上升快,下降快,峰值强度大,达峰时间早,上述参数差异均有统计学意义(P＜0.05).结论 时间-强度曲线和伽马拟合定量分析软件能较为真实客观地反映肝细胞癌及肝实质间不同的灌注特点,为肝肿瘤的诊断和血流动力学研究提供量化指标及诊断依据.     

健康管理对高校大学生高血压患者的干预效果分析

目的 探讨健康管理对高校大学生高血压的干预效果.方法 选取通过体检确诊为高血压的患者50例,随机均分为2组(n=25).实验组进行为期1年的健康教育管理指导,对照组不进行任何健康教育管理指导,比较2组患者收缩压、舒张压及BMI的统计学差异.结果 通过健康教育管理指导干预后,管理后实验组的血压收缩压、舒张压、BMI与管理前相比有明显的下降,并且下降的幅度明显高于对照组,差异有统计学意义(P<0.05).结论 通过对大学生进行健康教育管理可以把血压控制在正常范围内,使其保持良好的生活习惯,提高了大学生的生活、学习质量.     

术中灰阶及彩色多普勒超声在颅内病变诊断中的应用价值

目的评价术中灰阶及彩色多普勒超声在颅内病变诊断中的作用。方法对36例疑诊为脑肿瘤的患者去骨瓣后术中超声实时监测颅内实性肿瘤切除范围,显示颅内实性肿瘤部位、大小、深度、回声、内部血流信号及毗邻组织,引导术者确认脑动脉瘤位置、载瘤动脉及实性肿瘤的边界。手术结束前探查有无残余肿瘤及是否确切夹闭动脉瘤,对可疑残余颅内肿瘤取小块组织行病理检查。对实性病灶术中彩色多普勒超声图像与术前增强MR对比;夹闭动脉瘤后声像图与术后CT血管成像(CTA)对比分析。结果 (1)36例(39个病灶)术中超声清晰显示38个颅内病灶并准确定位,1例髓内病变未显示。(2)术中超声成功引导术者完全切除26例(26/28)胶质瘤,2例转移瘤(3个病灶),1例脑脓肿,1例脑缺血性梗死灶。2例脑胶质瘤不完全切除。完全夹闭2例动脉瘤及1例动脉瘤破裂机化灶的载瘤动脉。不完全切除的2例胶质瘤术后半年复发,术中超声不能区分复发肿瘤与首次手术填塞物。结论术中超声可准确定位并有助于制定手术方案,实时监测肿瘤切除情况,评价手术效果,最大程度降低手术对脑组织的损伤。     

深海鱼油对心血管亚健康人群作用的临床观察

目的:探讨深海鱼油对心血管亚健康人群各指标的改善作用。方法:将210例符合入组条件的志愿者随机分为治疗组和对照组,治疗组连续服用深海鱼油,对照组服用玉米油,时间3个月。服用前后分别测定两组人群体质指数、血压和血清总胆固醇、甘油三酯、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇、空腹血糖水平,并完成亚健康评估问卷测评。结果:治疗组收缩压、血清甘油三酯水平下降,亚健康评分和阳性率降低(P<0.05);对照组仅亚健康评分和阳性率降低(P<0.05)。结论:深海鱼油对心血管亚健康状态人群有改善作用。

患者女,58岁,以"右侧腰腹部疼痛伴全程肉眼血尿7日"入院.患者7个月前曾诊断为肾结石,间断接受体外超声波碎石4次,未有结石排出.入院查体:右中上腹肿物,表面触及小结节,质地硬,有压痛.     

超声造影时间-强度曲线与伽马拟合曲线对肝细胞癌的诊断价值

Objective To investigate the value and the enhanced mode of time-intensity curve(TIC)combined with gamma curve of contrast-enhanced ultrasound in diagnosis of hepatocellular carcinoma.Methods The ultrasonic contrast images of 34 patients with hepatocellular carcinoma by the gamma curve were obtained by the time before,increased branch slope parameter, curve sharpness, gamma modulus, peak time,peak intensity, the average pre-peak intensity, increased branch slope and pre-peak area.Results Compared with the peripheral hepatic parenchyma, the curve of the tumor tissue ascended as well as declined more rapidly, peaked earlier with a more intensive peak value.There were significant differences between the two groups in all the data mentioned-above (P＜0.05 ).Conclusions TIC and gamma fit quantitative analysis can reflect the different perfusion characteristics between hepatocellular carcinoma and normal hepatic parenchyma objectively and accurately,so as to provide the quantitative criterion and basis for the diagnosis and hemodynamic study of the hepatocellular carcinoma.

初中生情感与自我概念、学业成绩的相关研究

目的了解初中生的情感现状及情感与自我概念、学业成绩的关系。方法采用问卷法调查了太原市两所中学的503名初中二年级学生。结果 1初中生的消极情感较多,自我概念的水平也较低;2男女生在情感量表的得分无差异。家庭经济收入高的学生,体验到较多的正向情感（F=5.683,P〈0.05）;3初中生的正向情感与学业自我概念呈正相关（r学校=0.36,r言语=0.29,r数学=0.32,P〈0.01）,负向情感与学业自我概念呈负相关（r学校=-0.31,r言语=-0.30,r数学=-0.29,P〈0.01）;正向情感与语文、数学成绩呈正相关（r语文=0.22,r数学=0.26,P〈0.01）,负向情感与语文、数学成绩呈负相关（r语文=-0.33,r数学=-0.33,P〈0.01）。结论初中生的正向情感需要进一步培养和增进;情感与其学业自我概念、学习成绩中度相关。
