自体输血在出血性手术中的应用

外科手术,特别是出血量较大的急诊手术、术中出血较多的心内直视手术、以及颅脑外科手术等用血量大,一直是医疗中棘手的问题,而随着人们对输血所带来并发症的重视,以及近年来血源不足及合理输血、血液保护等,使得自体输血成为主流。本文就自体输血在临床应用,特别是大出血性手术中的应用价值作一综述。     

Cortical plasticity: effect of high and low intensity conditioning electrical stimulations (100 Hz) on SEPs to painful finger stimulation.

OBJECTIVE: To study the effect of high-frequency (100 Hz) repetitive conditioning electrical stimulation (CES, 10 min) on human somatosensory evoked potentials (SEPs) to evaluate if short-term cortical plasticity could be induced. METHODS: Painful electrical stimulations were applied to thumb (D1) and little finger (D5) fingertips, respectively. The 124-channel EEG was recorded from 10 healthy male volunteers. Peak stages around 34, 45, 212, 331 ms were analyzed with focal maximum amplitude (FA) and area magnitude (AM) of scalp field potential, topography, and equivalent current dipole source localisation, comparing before and after two-level CES (high- vs. low-level) applied to the He-Gu acupoint. RESULTS: After a high-level CES, the positive FA and AM of the current efflux showed a significant increase at the early phase 34 ms, and significantly decreased at 45 ms in D1 SEPs. The negative FA and AM of the current influx were significantly increased at late phase 350 ms of the D5 SEPs. Only 36 ms, the z-axis position of dipole was significantly changed from (x: -15.9 mm, y: 29.6 mm, z: 43.9 mm) to (x: -12.9 mm, y: 29.4mm, z: 51.5mm) for the D5 SEPs. CONCLUSIONS: The high-level CES significantly attenuated the subsequent cortical activation (45 ms peak for D1 stimulation). Both low- and high-level CES significantly enhanced the late activities (226, 350 ms) in D5 stimulation. This may be explained by pain sensation change at the level of subcortical cingulate cortex induced by the site-dependent post-effect of CES. SIGNIFICANCE: This study showed cortical plasticity induced by conditioning somatosensory stimulation.     

社区卫生服务:行走在点线面之间

2006开年,一个似曾相识的专有名词重返人们的视野——社区卫生服务,作为一种由政府强力推动的解困手法,被迅速纳入到有效缓解“看病难看病贵”的社会预期之中。由上而下的理论先导,只能经由行之有效的实践打磨才能得以还原。如果将整个社区卫生服务网络比作一个完整的神经系统,那么只有这个新     

大树倒了?

2004年8月26日,哈医大二院建院50周年庆典,位于哈市近郊的这所庞大的医院一扫往日的紧张忙碌,被欢快的乐、缤纷的鲜花、五色的气球和飞扬的条幅紧紧包裹。在庆典活动的中心——该院科技会馆,前去采访的本刊记者穿过络绎不绝的祝贺来宾和整齐划一的迎宾方阵,流连在会场外整齐摆放的各类奖杯、奖牌和科研成果宣传展板之间。这些被物化了的荣誉,几乎挤满了偌大的会堂一层走廊的每一寸角落,静静地宣示着这家医院半个世纪的所有自尊和自豪。在随后进行的庆祝仪式上,在医院各科室职工代表声情并茂的发言之后,哈医大二院院长张岂凡走上讲台。面对眼前如云的嘉宾和着装整齐统一的医护人员方阵,看得出这位著名的技术型院长难掩激情。他在题为“弘扬二院精神,再创世纪辉煌“的演讲词中这样形容：“50年的砥砺前行,50年的春华秋实,令天的哈医大二院已经成为我国医院之林中的一棵生机盎然的大树,根深叶茂,硕果累累。”命运总是在不动声色间逆转,谁能料到,一年后爆出的“天价医药费”事件,使曾经激情飞扬的哈医大二院再一次名动天下,所不同的是,再度亮相的哈医大二院,这一次坐在了被告席上。这棵生长了50年的医疗常青树,难道就此在瞬间轰然倒地?

Efficacy and safety of herbal medicines for idiopathic Parkinson's disease: a systematic review.

The objective of this study is to assess the efficacy and safety of herbal medicines (HMs), as a monotherapy or adjunct therapy, compared to placebo or conventional approaches in the treatment of idiopathic Parkinson's disease (PD). We conducted a systematic review of randomized controlled trials from both conventional and alternative medicine sources. Outcome measures were overall improvement, quality of life, reduction of levodopa dose, and adverse events. Nine studies were included, each testing a different HM. Six of the trials had limited internal validity due to major flaws in design, including the lack of proper randomization; insufficient blinding; unclear inclusive criteria in terms of diagnostic criteria, baseline staging, and duration of disease; lack of proper sample size calculation; and insufficient data analysis. Imbalances in gender and ethnicity among the patients in the included trials were observed. No major adverse events emerged, and no specific pattern was detected from the trials describing such data. In addition to major methodological defects, heterogeneity in (1) HM tested, (2) control treatment, and (3) outcome measure hindered in-depth data analysis and synthesis. Current evidence is insufficient to evaluate the efficacy and safety of various HMs. Further studies with improved trial design and reporting, with assessment on cost-effectiveness, quality of life, and qualitative data are warranted.
