吉林辽宁两省18年来的目标设置对突发公共卫生事件应急工作落实情况的关联研究

目的本研究立足于项目组前期研究的成果上，积极探索吉林辽宁两省目标设置水平的差异，并进一步探究受目标设置影响下的工作落实结果情况，探讨产生差异的原因。 方法以系统穷尽的方式收集吉林辽宁两省2000至2017年有关目标与工作落实情况的指标，利用Spearman相关和线性回归分析吉林辽宁两省目标设置对于突发应急工作落实情况的影响。 结果吉林辽宁两省突发应急领域的目标设置水平与工作落实情况总体均呈现上升趋势，截至2017年，吉林目标设置水平与工作落实情况分别为46%与60%，辽宁为60%与53.3%，且目标设置水平与工作落实呈正相关。 结论有公众需要为依据且定量可考的目标设置对于工作落实、推进、完善具有积极的正反馈作用，建立科学量化的突发应急目标设置评价体系是适宜可行的。     

The quality of spontaneous adverse drug reaction reports from the pharmacovigilance centre in western China

Background: High-quality adverse drug reaction (ADR) reports are essential for conducting drug safety monitoring in pharmacovigilance. The study aim was to assess the current quality of ADR reports in western China, and to identify problems with ADR report quality.

Research design and methods: A sample of 1139 reports received by the Shaanxi ADR Monitoring Center from January 2015 to December 2017 was selected. ADR report quality was evaluated using an ADR report quality evaluation system.

Results: None of the reports were rated as excellent and 1.40% (n = 16) as good. Report quality was better for new and serious reports than for general reports. Medical institutions generated higher quality reports than pharmaceutical manufacturers. Nurses generated higher quality reports than doctors, pharmacists, and other professionals. Reporters of different occupations showed significant differences in the quality of the indicators Reporting time limit, Intervention ADR time, ADR termination time, ADR intervention measures, Original disease, and Cause of medication (P = 0.000).

Conclusions: The ADR data quality was poor in western China, and of lower quality than reported data from previous research in other regions. Improvements in the quality and availability of ADR reports are urgently needed.     

神经电生理对腓总神经卡压的诊断价值

目的 观察神经电生理检测对腓总神经卡压的诊断价值。方法 对腓总神经卡压的临床特征及病因进行分析，并作神经传导速度和肌电图检测和分析。结果 21条患病神经中1条神经波形消失。其余有不同程度的传导速度减慢，尤其是跨腓骨小头段，波幅降低，传导时间延长，42块腓总神经支配的肌肉中有30块出现失神经电位。结论 神经电生理检查在腓总神经卡压的诊断中有重要意义。     

血管内皮生长因子及炎性因子在油酸性犬急性呼吸窘迫综合征中的变化

目的探讨油酸性急性呼吸窘迫综合征（ARDS）beagle犬血浆及肺泡灌洗液血管内皮生长因子（VEGF）、可溶性细胞间黏附分子-1（ICAM-1）、白细胞介素-8（IL-8）、肿瘤坏死因子-α（TNF—α）水平的改变。方法12只英国纯种beagle犬，静脉注射油酸0．15mL／kg，在注射油酸前、后1h，出现ARDS的典型表现时，抽血测VEGF、sICAM-1、IL-8、TNF—α，并对此时相作肺泡灌洗液VEGF、sICAM—1、IL-8、TNF-α的测定。结果beagle犬静脉注射油酸后1h血浆TNF—α升高（P〈0．05），血浆反肺泡灌洗液IL8、sICAM-1和VEGF在1h较油酸前没有明显变化（P〉0．05），beagle犬油酸型ARDS模型建立后血浆及肺泡灌洗液VECF、sICAM-1、IL-8、TNF—α均显著高于建模前（P〈0．05）。结论VEGF、sICAM-1、IL-8、TNF～α在beagle犬油酸型ARDS发生发展过程中可能均起重要作用，其水平的高低可能与ARDS严重程度及预后有关。     

Modified superficial parotidectomy: preserving both the great auricular nerve and the parotid gland fascia.

OBJECTIVE: To reduce the incidence of sensory deficits and Frey's syndrome by modifying the traditional superficial parotidectomy. STUDY DESIGN: After raising the skin flap, the parotid gland fascia (PGF) was elevated to form a posterior pedicle fascial flap and then was replaced after the gland removal. The great auricular nerve (GAN) that runs within the PGF was not separated, so both the GAN and the PGF were preserved. Before this modification, the GAN and PGF were examined anatomically. The complication rates in the modified and control groups were compared. RESULTS: 1) The GAN, which runs within the thick and pycnotic PGF, trifurcates into postauricular, preauricular and lobule branches. The modification could be carried out practically based on the anatomy study. 2) Long-term sensory deficit was encountered in 13.3% of the control group, but 0% in the modified one. Frey's syndrome was suffered by 66.7% and 16.7% cases in the control and modified group respectively. The incidence of other complications was not significantly different. CONCLUSION: Our modification is practical. It decreases the complications significantly. EBM rating: B-3b.     

11C-乙酸盐PET显像在肾脏肿瘤诊断中的作用

目的探讨^11C-乙酸盐PET显像在肾脏肿瘤诊断中的作用及其与^18F-脱氧葡萄糖（FDG）肾肿瘤显像的关系。方法29例疑肾肿瘤患者行^11C-乙酸盐PET早期及延迟显像，其中22例1周内行^18F—FDG PET显像。所有患者均有手术病理检查或CT、随访结果。患者静脉注射^11C-乙酸盐后即刻采集肾脏部位早期图像，以反映肾皮质血流灌注；10min后采集延迟图像，以反映^11C-乙酸盐在肾皮质内的代谢。观察^11C-乙酸盐在人体内的分布，并比较^11C-乙酸盐与^18F—FDG肾肿瘤显像的阳性率及其与病理类型、分级的关系。结果^11C-乙酸盐在人体内以胰腺摄取最高，并可能经胰液分泌人肠道。肾皮质对^11C-乙酸盐摄取随时间而变化，延迟相大部分原发肾皮质肿瘤（13例中分级Ⅰ～Ⅱ为12例）对^11C-乙酸盐摄取高于正常肾皮质，阳性率为76．9％（10／13例）；而^18F—FDG显像仅为30．8％（4／13例）。6例肾盂输尿管移行细胞癌^11C-乙酸盐显像阳性仅2例；其中5例行^18F—FDG显像，均阳性。1例肾血管平滑肌脂肪瘤^11C-乙酸盐早期及延迟显像均清晰显示，2例输尿管炎症对^11C-乙酸盐无摄取。结论^11C-乙酸盐PET显像对恶性程度较低的肾皮质肿瘤显像阳性率较高，可弥补^18F—FDG显像的不足。
