舒芬太尼用于全凭静脉麻醉40例研究

目的：探讨舒芬太尼全凭静脉复合麻醉时对听觉诱发电位指数、血流动力学和术后复苏的影响.方法：40例美国标准协会（ASA）Ⅰ～Ⅱ级病人择期行胆囊切除手术,随机分为Ⅰ组（舒芬太尼组）和Ⅱ组（芬太尼组）,记录两组病人麻醉期间各时间点的听觉诱发电位指数（AEPI）值、收缩压、舒张压、心率和SpO2.结果：Ⅱ组插管后1 min、2 min的收缩压较Ⅰ组升高,而插管后1 min的心率较Ⅰ组降低（P＜0.05）;Ⅰ组插管后1 min、2 min和3 min时的AEPI值低于Ⅱ组（P＜0.05）;Ⅰ组拔管后至定向力恢复的时间较Ⅱ组长（P＜0.05）;Ⅰ组丙泊酚的用量较Ⅱ组少（P＜0.05）.结论：等效剂量的舒芬太尼较芬太尼的全凭静脉复合麻醉可以使病人达到更为合适的麻醉深度,并能使血流动力学更加稳定,同时可减少丙泊酚用量.     

椎动脉形态学异常对后循环短暂性脑缺血发作症状持续时间的影响

目的 探讨椎动脉形态学异常对后循环TIA症状持续时间的影响。
方法 回顾性分析2015年10月-2018年3月在中国科学院大学重庆仁济医院神经内科完成头颈部DSA
或CTA的后循环TIA住院患者临床资料，根据症状持续时间分为<10 min组、10～59 min组和≥60 mi n组，
比较椎动脉形态异常各亚型在3组间的差异。通过多因素Logistic回归分析明确椎动脉形态异常与后
循环TIA症状持续时间之间的关系。
结果 共纳入237例患者，其中症状持续时间<10 min组109例（45.99%）、10～59 min组71例（29.96%）
和≥60 min组57例（24.05%）。一般临床资料的比较显示，性别、椎动脉和基底动脉狭窄率≥50%
在3组间差异具有统计学意义（P＜0.05）。椎动脉形态异常中，动脉粥样硬化性椎动脉狭窄（狭窄
率1%～99%）在3组间的差异具有统计学意义（P =0.004），而一侧迂曲、双侧迂曲、一侧优势、一
侧优势合并迂曲和起源异常在3组间差异均无统计学意义；多因素Logi sti c回归分析显示椎动脉
狭窄（OR 2.500，95%CI 1.381～4.525，P =0.002）、基底动脉狭窄率≥50%（OR 12.066，95%CI
1.446～100.668，P =0.021）是TI A症状持续时间延长的独立影响因素。
结论 椎动脉狭窄和基底动脉狭窄率≥50%是影响后循环TIA症状持续时间延长的独立影响因素。     

Whole-Blood Assay to Measure Oxidative Burst and Degranulation of Neutrophils for Monitoring Trauma Patients

AbstractBackground and Purpose: Polymorphonuclear neutrophils (PMNs) protect the host from invading microorganisms, but excessive PMN activation after trauma causes tissue injury. Rapid monitoring of PMN function is critical for the assessment of the inflammatory state of trauma patients. Here, the authors adapted two simple and rapid methods to measure oxidative burst and degranulation of human PMNs in whole blood to avoid potential interference of cell isolation procedures with the assessment of PMN function.Material and Methods: Heparinized blood was drawn from healthy volunteers or trauma patients, preincubated at 37 °C for 5 min, and stimulated with N-formyl-methionyl-leucyl-phenylalanine (fMLP). Four assays for oxidative burst were tested: (1) cytochrome C; (2) homovanillic acid (HVA); (3) Amplex^® Red; and (4) flow cytometry with dihydrorhodamine 123 (DHR). PMN degranulation was assessed with flow cytometry using antibodies to: (1) CD11b/Mac-1 (CD18); (2) CD63; and (3) CD66b (CD67).Results: With the exception of the DHR method, all methods to measure oxidative burst were found to be unsuitable in whole blood due to interference of plasma proteins and hemoglobin with the fluorimetric or photometric readouts. By contrast, all degranulation methods were suitable for whole-blood studies. However, for the assessment of formyl peptide-induced degranulation, anti-antibodies to CD11b/Mac-1 and CD66b were up to five times more sensitive than antibodies to CD63. Thus, the degranulation and DHR methods were optimized for increased sensitivity, speed, and specificity and their usefulness to measure PMN function in trauma patients was tested.Conclusion: The whole-blood methods based on flow cytometry with DHR, anti-CD11b/Mac-1, and anti- CD66b are rapid, simple, and reliable techniques to assess PMN function for trauma research.

AC/A ratios in myopic and emmetropic Hong Kong children and the effect of timolol§

Purpose: Caucasian children with myopia have elevated response accommodative vergence to accommodation (AC/A) ratios. The purpose of this study was twofold: to determine if response AC/A ratios vary with refractive error and with myopic progression rate in Hong Kong Chinese children, and to determine the effect of beta‐adrenergic antagonism with topical timolol application on AC/A ratios. Methods: Thirty children aged eight to 12 years participated in the study. All refractive errors were corrected with spectacle lenses. Accommodative responses were measured using a Shin‐Nippon autorefractor and concurrent changes in vergence were assessed using a vertical prism and a Howell‐Dwyer card at three metres and 0.33 metre. Accommodative demand was altered using plus or minus two dioptre lenses and lens‐ and distance‐induced response AC/A ratios were calculated. Measurements were repeated 30 minutes after the instillation of topical timolol maleate (0.5 per cent). Results: AC/A ratios appeared higher in progressing myopic children but the difference was not statistically significant. Timolol application reduced accommodative convergence (AC) in the stable myopes (reduction = ‐3 ± 1.14^A) but not in the emmetropes (0.69 ± 0.9^P) or progressing myopes (0.16 ± 0.43^A) and this difference between refractive groups was statistically s ignificant (F^2,27= 3.766; P= 0.036). However, timolol did not produce a significant change in the accommodative response to positive or negative lenses or response AC/A ratios. Conclusions: We did not find that AC/A ratios in myopic Chinese children were elevated and therefore, it is unlikely that elevated AC/A ratios are responsible for the high levels of myopia that occur in Hong Kong. The finding that timolol reduced AC in the stable myopes suggests that the autonomic control of accommodative convergence in these children may be different from that in emmetropic children and those with progressing myopia.
