Percutaneous microwave coagulation therapy under ultrasound guidance for small hepatocellular carcinoma.

BACKGROUND AND PURPOSE: Percutaneous microwave coagulation therapy (PMCT) can effectively treat hepatocellular carcinomas (HCCs) smaller than 2 cm. However, for tumors 2 to 3 cm in size, combination of transarterial chemoembolization (TACE) or multiple insertions of electrodes may be more effective. This study investigated the treatment efficacy of PMCT for tumors 2 to 3 cm in size. METHODS: Nineteen HCCs smaller than 3 cm in diameter (< 2 cm in 11, and 2-3 cm in 8) in 18 patients (including 14 previously treated patients) were treated by PMCT under ultrasound guidance. One or 2 PMCT electrodes were consecutively inserted either into the left and right portion, or into the distal and proximal portion of the tumor, according to the size, shape, and margin of tumors and puncture direction. Liver function tests and contrast-enhanced computed tomography were used to examine preoperative status and response to PMCT. RESULTS: After an average of 1.6 emissions of PMCT, 18 tumors (95%) were completely ablated. The only case of treatment failure was due to a tumor location which made the approach of the electrode difficult. Bacteremia developed after the procedure in 1 patient (5%) and local inflammatory reaction of the puncture wound in another (5%). During follow-up ranging from 5 to 19 months, no recurrence was noted at the site of the original tumors. Tumor recurrence was detected at another site 2-9 months after PMCT in 9 of the 14 previously treated patients. CONCLUSION: PMCT can effectively and safely treat HCCs smaller than 3 cm in size without combination of TACE or multiple insertions of electrodes.     

企业工人保健意识、技能及保健用品配备现状调查

目的为了解企业工人自我保健的态度、知识、技能与保健用品配备的现状,为探索企业开展健康教育与健康促进提供参考依据。方法在大连造船重工集团和大连船用柴油机厂,采取分层抽样的方法对328人,由经过统一培训的调查员进行问卷方法进行调查。结果被调查的328人中,认为疾病可以预防的有315人,占96.0%;认为家庭应该配备保健用品的有275人,占83.8%;认为学习和掌握保健知识与方法对健康有好处的有319人,占97.3%;最关心的问题是身心是否健康的有294人,占89.6%。结论对企业工人广泛开展健康教育,特别是进行有针对性的保健技能的培训,对于促进自我保健水平的提高具有积极的意义。     

原发性肝癌的诊治进展

原发性肝癌(以下简称肝癌)是我国最常见的恶性肿瘤之一,自20世纪90年代以来,肝癌的年病死率已上升为城市和农村恶性肿瘤病死率的第二位和第一位。目前,外科治疗为主的综合治疗已经成为肝癌治疗的主流。随着认识的不断深入,一些新观念也相继进入临床。一、诊断在临床上,肝癌的诊断包括定性诊断和定位诊断两个方面。目前以高危人群为主要诊断对象的肝癌临床诊断体系已经较为完善,如果遵循甲胎蛋白(AFP)/AFP异质体+乙型肝炎病毒(HBV)免疫标志物+B超→CT或/和MRI(必要时行肝动脉造影)的诊断步骤,实验室检查与影像学检查相结合,可使绝大多…     

上田法和电脑中频协同治疗脑性瘫痪

目的探讨上田法和电脑中频协同治疗小儿脑性瘫痪(脑瘫)的疗效。方法观察和评定上田法和电脑中频协同治疗小儿脑瘫60例的疗效;收集和评定此前本科单用上田法治疗小儿脑瘫56例的疗效,比较两者连续治疗4个疗程(120 d)后疗效。结果上田法和电脑中频联用总有效率96.7%,单用上田法总有效率82.1%,两者比较有显著性差异(P<0.05)。结论上田法和电脑中频协同治疗小儿脑瘫有显著疗效。

Causal influences in primate cerebral cortex during visual pattern discrimination

Anatomical studies of the visual cortex demonstrate the existence of feedforward, feedback and lateral pathways among multiple cortical areas. Yet relatively little evidence has previously been available to show the causal influences of these areas on one another during visual information processing. We simultaneously recorded event-related local field potentials (LFPs) from surface-to-depth bipolar electrodes at six sites in the ventral region of the right hemisphere visual cortex in a highly trained macaque monkey during performance of a visual pattern discrimination task. Applying a new statistical measure, the short-time directed transfer function (STDTF), to the LFP data set, we charted the changing strength and direction of causal influence between these cortical sites on a fraction-of-a-second time scale. We present results showing, for the first time, the dynamics of distinct feedforward, feedback and lateral influences in the ventral portion of the primate visual cortex during visual pattern processing.     

丹参酮ⅡA对兔髂动脉球囊损伤后胶原生成抑制的效应观察

目的:观察兔髂动脉损伤后,丹参酮ⅡA治疗组中膜平滑肌细胞(SMC)周围胶原变化的趋势.方法:取体重2.5～3kg纯种雄性新西兰大白兔30只,球囊导管扩张法制作左髂动脉内膜球囊损伤模型,术后分配到治疗组和对照组.治疗组丹参酮ⅡA稀释静脉注射,疗程6天;对照组采用等量生理盐水静脉注射.术后7天、14天和28天处死实验兔,将左侧髂动脉取出制作石蜡切片,并作胶原染色.结论:术后7天治疗组和对照组胶原纤维染色均不明显,术后14天和28天对照组SMCs周围可见胶原染色阳性,红染增多;治疗组14天SMCs周围也可见红染增多,但28天红染不明显;两组差异以术后28天明显(P=0.017);胶原染色随时间变化的趋势有统计学意义(P=0.005).结论:丹参酮ⅡA有抑制血管损伤后细胞外基质堆积的作用,从而可能有防治术后再狭窄的效应.
