Relapsing bacterial meningitis in adults

Relapsing bacterial meningitis is a rare condition, diagnosedin eight patients between 1981 and 1993 at our institution.These accounted for 3.4% of 234 adult patients with blood and/orcerebrospinal fluid culture-proven bacterial meningitis. A reviewof the English-language literature from 1966 to the presentrevealed only five further adult cases of relapsing bacterialmeningitis with in-depth case histories. Of these 13 total patients,nine were female and four male, aged 17–61 years. Tenwere neurosurgical patients. Gram-negative bacilli, especiallyKlebsiella species, were the commonest micro-organisms identifiedfor both the initial episode and the relapse of infection. Threepatients died in the course of relapse. Four or more weeks ofantibiotic therapy may be needed to treat post-surgical patientswith Gram-negative bacillary meningitis. Even a normal cerebrospinalfluid study at the end of treatment of bacterial meningitisis not a guarantee of freedom from relapse.     

金尔伦治疗急性颅脑损伤的剂量效应研究

目的探讨金尔伦(盐酸纳洛酮)在治疗大鼠液压脑损伤后神经功能恢复和病理损害程度的剂量效应.方法将104只SD大鼠随机分为4组,伤后早期分别腹腔注射0.03 mg/Kg(小剂量组)、0.3 mg/Kg(中剂量组)、3 mg/Kg(大剂量组)金尔伦和等量生理盐水(对照组),连续7 d.结果中、大剂量组动物伤后脑神经功能恢复、脑水肿减轻程度及光、电镜检查显著优于对照组及小剂量组.结论伤后早期使用中剂量和大剂量金尔伦(盐酸纳洛酮)对大鼠液压颅脑损伤有明显的治疗效果.     

粗糙脉孢菌漆酶基因的克隆及在毕赤酵母中的初步表达

采用连续延伸PCR方法克隆到粗糙脉孢菌（Neurospora crassa）漆酶基因，并将其克隆到表达载体pPIC9k，重组质粒经线性化、电激转化Pichia pastoris KM71，部分阳性克隆的PCR结果表明：漆酶基因已整合到巴斯德毕赤酵母染色体上，重组菌经甲醇诱导后3～5d产漆酶量最高，为2-3U／mL。     

A Latex Finger Strip and Nylon Zip-Tie Combo as a Tunable Digital Tourniquet

BACKGROUND: Surgery on digit and nail requires a clear bloodless field that is often achieved by a tourniquet. OBJECTIVE: The objective is to present a simple, effective, and safe tourniquet for digital surgery. MATERIALS AND METHODS: A latex glove and a nylon zip-tie were used. A long strip is cut from the little finger tube of a latex glove. This is used for wrapping around the digit for exsanguination. The pressure is then maintained with a household nylon zip-tie. The finger strip is then cut to expose the operative field ready for surgery. The tourniquet pressure can be adjusted by tightening or loosening of the nylon zip-tie. RESULTS: Exsanguination and a bloodless field can be effectively achieved. The long tail of the nylon zip-tie reminds the operator to remove it at end of the surgery. CONCLUSION: A latex strip and nylon zip-tie combo serves as a simple, effective, and safe tourniquet for digital surgery.     

造影剂到达腹主动脉的峰值大小与患者因素的关系

目的探讨造影剂到达腹主动脉的峰值大小与患者因素之间的关系。方法108例患者以2.5ml/s注射欧乃派克(300mgI/ml)20ml,12s后采用testbolus技术在腹腔干水平同层动态扫描腹主动脉,用dynamic evaluation软件测得腹主动脉的峰值大小,采用单因素回归分析和多因素逐步回归分析法研究患者的性别、年龄、身高、体重、心率、血压、注射位点、达峰时间及是否有心脏病、糖尿病、或化疗史对造影剂到达腹主动脉峰值大小是否有影响及影响程度。结果造影剂到达腹主动脉峰值大小,在男性平均比女性低;其随年龄、身高、体重、达峰时间的增加而逐渐降低,注射位点在手背静脉其值平均比在肘部静脉低;其不受心率、血压、是否有心脏病、糖尿病或化疗史的影响。参考公式:峰值大小(HU)=383.8400-身高(cm)×1.0909-体重(kg)×0.6760 注射位点×16.7878-达峰时间(s)×1.6882。结论可根据患者的性别、年龄、身高、体重、注射位点和达峰时间来适当调整患者CT血管成像时造影剂用量。     

血管内栓塞治疗颅内动脉瘤围手术期护理

我院2003年6月~2006年10月应用电解可脱式铂金微弹簧圈对65例颅内动脉瘤病人进行血管内栓塞,配合术前术后有效的护理,取得良好的治疗效果,现就护理体会报告如下。1材料与方法本组65例,男29例,女36例,年龄26~67岁,平均年龄45岁。以自发性蛛网膜下腔出血(SAH)为首发症状61例,头痛头晕3例、肢体麻木无力1例。本组65例中,45例在神经麻醉下,20例在气管插管全身麻醉下实施栓塞术。全身肝素化抗凝下,采用Seldinger’s技术经股动脉穿刺插管行全脑血管造影术(DSA),沿微导管放入直径与动脉瘤体匹配的电解可脱式微弹簧圈,电解解脱后,复查脑血管造影,…     

深静脉置管预防阿昔洛韦致静脉炎的效果观察

目的探讨深静脉置管术预防阿昔洛韦致静脉炎的效果。方法随机将60例病毒性脑炎患者分为观察组和对照组各30例。观察组行深静脉置管,对照组采用头皮静脉针行静脉输入阿昔洛韦。结果观察组静脉炎发生率(16.7%)显著低于对照组(93.3%),差异有显著性意义(P<0.01)。结论深静脉置管可明显减少阿昔洛韦所致静脉的损害程度,降低静脉炎的发生率。
