中药蝶脉灵注射液在心肺复苏中脑保护作用的实验研究

目的 探讨中药蝶脉灵注射在心脏骤停时对脑复苏的作用。方法 用电刺激导致室颤制备家兔心脏骤停模型，在光镜和电镜下观察大剂量肾上腺素治疗时，蝶脉灵注射液对脑组织的影响。结果 蝶脉灵注射液对脑细胞有明显的保护作用。结论 蝶脉灵注射液能明显改善心脏骤停时脑缺血性损害，因而有利于脑复苏。     

踝部开放性骨折的急症手术治疗

目的探讨踝部开放性骨折的损伤特点及相关的急症手术技术特点。方法2001年8月至2006年4月，急症手术治疗踝部开放性骨折51例，男39例，女12例；年龄18-72岁，平均36岁。伤口Gustilo分度，Ⅰ度3例，Ⅱ度37例，ⅢA度7例，ⅢB度3例，ⅢC度1例。急诊给予有效抗生素治疗，尽早开始手术。冲洗及彻底清创后，根据骨折类型、粉碎程度及伤口情况制定骨折处理的顺序，依次完成骨折复位、固定。结果48例患者获得随访，随访时间8-48个月，平均26个月。无一例发生深部感染。12例伤口发生浅表皮缘坏死，2例伤口延迟愈合，2例伤口发生浅表感染。踝部骨折在10-18周（平均13周）愈合。采用AOFAS踝后足功能评分标准，48例评分在76-100分，平均90分。结论踝部开放性骨折在急症手术时应彻底清创，注意保护皮肤活力。在处理后踝骨折时，可采用胫骨远端脱出法。多数手术应先精确复位、固定外踝骨折，对旋后内收型、外踝严重粉碎的踝部骨折应先进行内踝骨折的复位、固定。对严重的下胫腓联合分离，应直视下复位且常规使用下胫腓螺钉固定。     

Anatomic and spiral computed tomographic study of the genial tubercles for genioglossus advancement.

OBJECTIVE: To measure and compare Chinese mandibular genial tubercles measured anatomically and with computed tomography (CT). STUDY DESIGN AND SETTING: Spiral CT scans were taken of 40 adult human skulls; the superior genial spines were measured using anatomic and CT methods. RESULTS: The height and width of the superior genial spines, mandible thickness, and distance from the menton to the inferior and superior margins of the superior genial spines were 5.82 +/- 0.71, 6.98 +/- 1.35, 11.95 +/- 1.59, 11.08 +/- 2.05, and 16.91 +/- 2.30 mm from anatomic measurements and 6.17 +/- 0.71, 7.01 +/- 1.13, 12.19 +/- 1.64, 10.41 +/- 1.55, and 15.73 +/- 2.12 mm using spiral CT, respectively. The anatomic and CT measurements were correlated. CONCLUSION: Spiral CT of the genial tubercles can help locate the osteotomy in genioglossus advancement. SIGNIFICANCE: This study acquired reference data on Chinese genial tubercles demonstrating that CT measurements of the genial tubercles reflect their anatomy, which should allow accurately locate the osteotomy.     

National Alliance for Oral Health Consensus Conference on Medically Necessary Oral Health Care: Legal issues

This paper examines medical malpractice law as it applies to medically necessary oral health care. The basic legal concepts and reported cases involving medically necessary oral health care are reviewed. It is concluded that dental professionals and consumer advocates must advance their educational and legislative advocacy efforts so that health professional colleagues and the public will become aware of the importance of these services and insurers will routinely include coverage of medically necessary oral health care in their medical and dental policies. While failure to provide medically necessary oral health care can be violative of patient rights and legally actionable, medical malpractice litigation should always be the behavior modifier of last resort.     

三种不同品系小鼠在肺肿瘤短期诱发试验中的敏感性比较

用不同剂量尿烷一次腹腔注射，对ＫＭ、ＢＡＬＢ／ｃ和Ａ／Ｊ系小鼠进行肺肿瘤短期诱导试验，以比较其敏感性，为环境化学物致癌性鉴定的实验条件提供依据。结果显示：以肺肿瘤发生率和平均发瘤数两项指数来衡量发瘤危险，Ａ／Ｊ系均在最低染毒剂量（２５ｍｇ／ｋｇ）即出现发瘤危险明显增高；ＫＭ系以发生率衡量时，１００ｍｇ／ｋｇ为发瘤危险增高的最低剂量，而以平均发瘤数衡量时，最低剂量为２００ｍｇ／ｋｇ；ＢＡＬＢ／ｃ系前     

眼内异物合并外伤性白内障的联合手术治疗：附88例分析

眼内异物合并外伤性白内障是眼外伤常见的致盲原因之一,各地报告的致盲率为20%～48.9%。本文对88例眼内异物合并外伤性白内障患者采用联合手术治疗,收到较好疗效,术前视力0.05以下占85.2%,术后矫正视力0.05以下占27.3%,矫正视力0.06～1.5占73.7%,其中矫正视力0.6～1.5者占22.8%。根据异物的性质、在眼内部位和晶体损伤情况选择不同的手术方式一次联合手术摘出异物和白内障,术后采用中西药配合治疗。联合手术可提高疗效,减少术后并发症.减少手术次数,减轻病人的痛苦,缩短病程,减少医疗费用.眼科学报1993;9:216—218.
