胰胆管合流异常动物模型的建立

目的建立胰胆管合流异常的动物模型。方法选用健康杂种猫10只。术前禁食12 h,3.5%戊巴比妥钠麻醉后,取上腹正中切口约6 cm切开各层至腹腔。于胆总管入十二指肠处旁边,切开胰腺背膜,解剖胰管;靠近十二指肠处分别纵向切开胰管、胆管长约4~6 mm的切口。6-0线间断吻合切口,造成类似人类的胰胆管合流的共同通道。术后20天胆道造影。结果术后动物精神、食欲良好,无萎靡、烦燥等表现,造影显示胰胆管合流共同通道延长。结论本动物模型最接近于人类的胰胆管合流异常生理,优于其他动物模型。     

重度苯妥英钠中毒的药学监护

目的首先确定中毒药物,然后通过测定血药浓度以了解中毒程度,为重度苯妥英钠中毒患者临床抢救治疗提供依据。方法间隔一定时间采集患者静脉血,萃取血中药物,在211 nm处以反相高效液相色谱法定性,明确中毒药物并测定血药浓度。结果在苯妥英中毒患者中最高血药浓度为68.94 mg.L-1,接近治疗浓度上限的3.5倍。结论患者为重度中毒,危及生命,需临床药师与临床医师积极配合,施行全程药学监护。

Sternum insufficiency fracture presenting as acute chest pain: a case report and review of the literature.

The spine, pelvic bones and long bones of the lower extremities are common sites for insufficiency fractures. Cases of sternum insufficiency fractures have been rarely reported in an elderly patient. Insufficiency fracture tends to occur in bones with decreased mechanical strength. It tends to occur in elderly patients, especially in postmenopausal women, with underlying diseases. We describe a case of sternum insufficiency fracture in a patient with rheumatoid arthritis and systemic lupus erythematosus on long-term corticosteroid therapy diagnosed in an emergency setting. Sternum insufficiency fracture is a rare cause of chest pain. This case serves to remind the emergency physician to remain vigilant for other noncardiac and nontraumatic causes of chest pain. If diagnosed accurately, these patients can be discharged and treated as outpatients.     

Evaluation of mandibular block using a standardized method.

The purpose of this prospective randomized study was to investigate the manifestations and efficiency of mandibular block (MB) using a standardized method. In this study, 123 patients requiring MB were randomly assigned to receive MB using a repeated measures design. Mandibular block was administered in each patient by using 2.1 mL of 2% lidocaine with 1:100 000 epinephrine for the inferior alveolar nerve, lingual nerve, and/or buccal nerve. Clinical parameters including the electric pulp test and test for soft tissue sensation using a sharp dental explorer were assessed on both the operated side and contralateral side before and 5, 10, and 15 minutes after injection, and at the end of surgical procedure. Results of the test of the contralateral tooth served as the control group. No response to the electric pulp test at a maximum output (80 readings) was used as the criterion for pulpal anesthesia. Results obtained with electric pulp test and sharp explorer test were not significantly different during various intervals on the contralateral side, indicating the reliability of this standardized method for assessing MB. The MB technique achieved a high rate of subjective numbness (100%) according to the perception of the patients of overall numbness and lip numbness. Overall anesthetic success rates of pulpal anesthesia were 5.7% for the central incisor, 38.2% for the canine, 55.3% for the first premolar, and 90.2% for the first molar. No significant difference was found in the efficiency of anesthesia related to sex or age of the patients. A slower onset of pulpal anesthesia after MB was found for the anterior teeth than for the posterior teeth. This study suggests that the use of a standardized method might produce a clearer and more comprehensive evaluation of the efficiency and manifestations of MB.     

低位直肠癌保留神经的腹膜外侧方扩大清扫的效果分析

目的 探讨低位直肠癌保留神经的腹膜外侧方扩大清扫对患者术后生存率、排尿功能和性功能的影响。方法 回顾性分析我院1996年1月至2000年6月期间收治的392例进展期低位直肠癌实施保留神经的根治性切除术患者的临床资料，其中行腹腔内清扫173例，腹腔内加腹膜外侧方清扫219例，2组患者在年龄、性别、浸润肠壁深度及肿瘤病理组织学类型方面差异无统计学意义。结果 腹腔内加腹膜外侧方清扫组侧方淋巴结转移率为17．8％（39／219），侧方盆壁非连续性癌灶转移率为5，9％（13／219）。术后发生排尿功能障碍：腹腔内清扫组7例（4．0％），腹腔内加腹膜外侧方清扫组113例（51．6％），2组比较差异有统计学意义（P〈0．01）；性功能障碍：腹腔内清扫组93例男性患者中有12例（12．9％），腹腔内加腹膜外侧方清扫组119例男性患者中有62例（52．1％），2组比较差异有统计学意义（P〈0．01）；局部复发率：腹腔内清扫组为16．2％（28／173），腹腔内加腹膜外侧方清扫组为9．6％（21／219），2组比较差异有统计学意义（P〈0．05）；5年生存率：腹腔内清扫组为49．1％（85／173），腹腔内加腹膜外侧方清扫组为59．4％（130／219），2组比较差异有统计学意义（P〈0．05）。结论 低位直肠癌保留神经的腹膜外侧方扩大清扫，可以减少局部复发，提高患者5年生存率，但也会影响患者术后排尿和男性性机能。

危重症患者的APACHEⅡ评分与中医辨证相关性研究

目的：通过比较不同中医证型的ICU危重症患者的APACHEⅡ评分，同时对比两组死亡率，评价中医辨证在预后判断中的临床意义。方法：对纳入研究的85例ICU危重症患者于入ICU及出ICU时分别进行中医辨证，分为阳类证和阴类证两型，对所有病人进行APACHEⅡ评分，比较两型病人在进入ICU及出ICU时的APACHEⅡ分值，并与死亡率比较。结果：初始为阴类证的患者在入ICU及出ICU时的APACHEⅡ评分显著高于初始为阳类证的患者（P=0．0001及F〈0．05），死亡率亦显著高于阳类证患者（P=0．0369）：治疗后由阳类证转为阴类证患者APACHEⅡ评分较维持阳类证者增高（P=0．0161），而阴类证转为阳类证的患者APACHEⅡ分值较维持阴类证者减低（P=0．0424）。结论：中医证型对危重症的病情程度及预后判断有较好的预测价值，阴类证患者的预后较阳类证患者差，证型转换可能引起预后改变。
