实时三维超声心动图定量评价左心室容量-时间曲线的可行性与准确性研究 总被引:5,自引:0,他引:5
目的:探讨实时三维超声心动图(RT-3DE)定量评价左心室容量-时间曲线的可行性及准确性。材料和方法:以心脏磁共振(CMR I)为“参考标准”,应用RT-3DE评价31例健康志愿者左心室容量-时间曲线,获得峰值排空率(PER)、峰值充盈率(PFR)等左心室功能指标。结果:30例健康志愿者获得了内膜边界清晰的三维图像和左心室容量-时间曲线;RT-3DE图像采集及分析时间明显短于CMR I;PER,PFR测值RT-3DE与CMR I间无统计学差异(P>0.05),具有良好的相关性(r分别为0.913,0.786)。结论:RT-3DE是一种定量评价左心室容量-时间曲线的可行、准确的新方法。 相似文献

CASE REPORT: The reported female patient underwent sub-total resection of an intra-medullary cervicothoracic astrocytoma classified as WHO grade II in 1984 at the age of 18 months and received local irradiation. In 1989, a local recurrence was diagnosed and a partial resection was performed. Sixteen years later, a small recurrent cervicothoracic tumour was found and spinal seeding to the equine nerve roots and the left cerebellar cortex was apparent on MRI. The patient was implanted with a ventriculoperitoneal shunt for a pseudo-tumour cerebri producing papilloedema, which eventually lead to amaurosis. After an extended biopsy, the invasive lumbosacral tumour was classified as glioblastoma multiforme. Two months later, the patient died after rapid progression of the caudal cranial nerve dysfunction. DISCUSSION AND CONCLUSION: Anaplastic progression and dissemination of spinal astrocytomas even two decades after initial diagnosis and treatment are rare. Therapies and diagnostic follow-up strategies are discussed. 相似文献

小儿病毒性脑膜炎病原诊断与临床分析 总被引:9,自引:1,他引:8
应用酶联免疫吸附(ELISA)方法,对88例临床诊断病毒性脑膜炎患儿急性期及恢复期脑脊液进行了单纯疱疹病毒(HSV-I、HSV-Ⅱ)、柯萨奇B组病毒(CoxBV)、埃可病毒(ECHO)、EB病毒(EBV)、腺病毒(AdV)及流感病毒(IFV)特异性IgM抗体检测。结果表明:HSV、CoxBV、ECHO、EBV、AdV、IFV病毒感染率分别为9.09%、18.18%、22.72%、3.41%、4.54%、5.68%;HSV及EBV感染致残率及病死率分别为87.5%(7/8)和100%(3/3)。提示脑脊液中病毒特异性IgM抗体检测可作为早期病原诊断的指标之一;CoxBV及ECH病毒是本地区小儿中枢神经系统病毒感染的主要病毒;HSV及EBV感染致残率及病死率较其它病毒高,预后不良;早期阿昔洛韦治疗,可大大降低病死率。 相似文献

Over 800 Maine residents will be diagnosed with colorectal cancer (CRC) this year, and nearly 300 will die from the disease.
While CRC screening can reduce these rates, it is only among insured populations that screening rates exceed 50%. This project
aimed to reduce barriers to, and increase rates of CRC screening among underinsured and uninsured women, ages 50 years and
over, residing in Cumberland County, Maine. The existing network of the Maine Breast and Cervical Health Program (MBCHP) was
used to reach the target population. A packet containing (1) an offer for no-cost fecal occult blood test (FOBT) screening
and CRC-related educational materials, and (2) a stamped, addressed postcard specifying the woman’s interest in these resources,
was mailed to 300 MBCHP enrollees residing in Cumberland County. Women requesting screening were contacted by phone to further
determine eligibility. Ninety-three women (31%) requested FOBT kits and 29 of these women requested educational materials.
Ten women were ineligible for screening because of previous colonoscopy. Fifty-two completed FOBT kits (63%) were returned;
all were negative. An additional 42 (14%) women requested educational materials only. To reduce the burden of CRC in Maine
and nationally, disparate populations must be reached with efficient and effective screening services. Established networks
are proven means for reaching uninsured and underinsured individuals with education, screening services, and necessary follow-up
care. This project serves as a model for the future development of similar programs statewide and nationally. 相似文献

Corporations have engaged in sponsorship of health management programs and, more recently, disease management programs to facilitate healthy and productive work environments. The purpose of this review is to examine the health and financial outcomes from these corporate-sponsored disease management programs. This article focuses on seven diseases or chronic conditions (arthritis, asthma, cancer, depression, diabetes mellitus, heart disease, and migraine) that potentially impact employee productivity (both in time away from work and in loss of effectiveness at work) and health status including medical and pharmaceutical utilization and costs.Corporate-sponsored disease management programs typically focus on education and screening for selected diseases or chronic conditions. Partnerships have been formed with health plans and third-party program providers to reach employees with interventions and treatment. The typical outcome measures from these programs have primarily been clinical indicators and medical utilization. Measures of productivity need to be incorporated as important outcome measures for disease management programs.The estimated financial opportunity for the corporation is a reflection of the cost differential for a given disease and the prevalence of that disease within the employee population. Primary diseases, chronic conditions, and health risks contribute to increased medical utilization and decreased productivity within the corporation. Promoting programs that focus on the whole person, including health risks, chronic conditions, and diseases, will likely increase the possibility of success in helping the employee to better self-manage their health conditions and consequently provide gains for both the individual and the corporation. 相似文献

It is important to acknowledge the harmful effects of environmental chemicals in human’s lives. The toxic effects of Diethylstilbestrol (DES), one of the endocrine-disrupting chemicals (EDCs), have been documented in many studies. As expected, DES affect male gendal hormone as well as female’s; therefore, epigenetic study should be considered. In this study, microarray technology was used to study harmful effects on the level of genomics, and here, two types of microarray chips- the Agilent mouse genome 4 × 44 K array for gene expression profiling and the Agilent mouse miRNA v13 for miRNA expression profiling-was used to study the relation between gene and miRNA expression profiles. As a result, we identified 4 miRNAs (miR 203, 350, 421, and 466i) that were similarly expressed at 3 hrs and 24 hrs of DES treat times. Twenty one genes matched between predicted target for 4 miRNAs and 118 genes expressed similarly. These genes have functions related to cell differentiation and cell cycle. Therefore, DES affects cellular function and induces toxicity in TM4 cells. In future studies, it is necessary to find more related functions and mechanisms of DES in the system. 相似文献
