比较手术夹闭和介入栓塞治疗颅内未破裂动脉瘤安全性和有效性的Meta分析

目的比较手术夹闭和介入栓塞治疗颅内未破裂动脉瘤的安全性和有效性。方法计算机检索1990至2018年颅内未破裂动脉瘤的所有临床对照研究。两名研究员分别纳入研究、提取数据、质量评价并应用Rev Man5. 0软件进行数据处理。结果最终纳入21篇文献,病例数109114例。Meta分析结果提示:手术夹闭组动脉瘤闭塞率为88. 2%,平均住院时间7. 7天,均高于介入栓塞组的65. 3%和4. 1天,P 0. 05。介入组患者的短期死亡率和致残率分别为0. 61%和2. 1%,均低于手术组的1. 27%和4. 7%,P 0. 05。介入组患者的1年期死亡率和致残率(2. 5%、2. 5%)均与手术组(2. 2%、1. 8%)无明显差异,P 0. 05。漏斗图未发现发表偏倚。敏感性分析结果一致。结论介入栓塞相比于手术夹闭可缩短患者的住院时间,降低患者的短期不良预后发生率。但是动脉瘤的闭塞率较低,1年期预后与手术夹闭无明显差异。据此推测手术夹闭患者的长期预后可能要好于介入栓塞,手术夹闭更适合于年轻患者。     

恶性肿瘤靶向药物治疗后口腔黏膜炎中西医研究进展

查阅近10 年中西医防治恶性肿瘤靶向药物治疗后口腔黏膜炎的相关文献，对其中西医发病机制、防治方法展开系统整理与分析。本病的发病机制尚未明确，现代医学认为可能与靶向药物治疗的作用机制相关，防治措施以口腔护理、支持性治疗为主，皮质类固醇激素对依维莫司相关性口腔炎疗效显著。靶向药物治疗后口腔黏膜炎属中医口疮、口糜等范畴，以脏腑功能失调、火热上挠口舌为主要病机，病位以心、脾、肾为主，治则上以清热泻火、调理脏腑阴阳为主，可分为清热解毒、清心泻脾、清热祛湿、养阴清热、健脾泻火五种治法。扶正抗癌法联合靶向药物使用可预防口腔黏膜炎的发生。     

医养结合型养老机构卫生服务质量指标体系构建研究

目的:构建基于SERVQUAL模型的医养结合型养老机构卫生服务质量评价指标体系。方法:围绕医养结合型养老机构卫生服务的概念、特性、内涵、内容等,采用文献研究法、半结构式访谈法、Delphi—AHP法等定性与定量相结合的研究方法,构建指标体系并确定指标权重。结果:构建了具有7个一级指标,27个二级指标和77个三级指标的养老机构卫生服务质量评价指标体系。指标体系三轮咨询专家权威系数Cr均高于0.84,专家综合权威性系数均高于0.83;总体专家协调系数Kendall W第一、二轮为0.309,第三轮为0.706,且均通过显著性检验;内容效度指数I-CVI介于0.90~1.00之间,S-CVI为0.94,kappa值均高于0.74;信度系数Cronbachα总体为0.972,各维度Cronbachα系数在0.792~0.921之间。评价指标体系具有较好的稳定性、可靠性和一致性。结论:本研究建立的评价指标体系有利于医养结合型养老机构全面建立贴近老年人卫生服务需求的内设医疗机构,改善机构内卫生服务质量。在对指标体系进行应用时,可转化为机构中老年人对各指标项目的感受(P)与期望(E),以两者的差值(P-E)代表机构的卫生服务质量。根据专家赋权结果,应重点加强医养结合养老机构对可靠性、有效性、经济性等指标项目的建设。     

Human encephalitis caused by pseudorabies virus infection: a case report

Pseudorabies virus (PRV) primarily infects swine but can infect cattle, dogs, and cats. Several studies have reported that PRV can cross the specie barrier and induce human encephalitis, but a definitive diagnosis of human PRV encephalitis is debatable due to the lack of PRV DNA detection. Here, we report a case of human PRV encephalitis diagnosed by the next-generation sequencing (NGS) of PRV sequences in the cerebrospinal fluid (CSF) of a patient. A male pork vendor developed fever and seizures for 6 days. NGS results showed PRV sequences in his CSF and blood. Sanger sequencing showed that PRV DNA in the CSF and PRV antibodies in both the CSF and blood were positive. MRI results revealed multiple inflammatory lesions in the bilateral hemisphere. Based on the clinical and laboratory data, we diagnosed the patient with PRV encephalitis. This case suggests that PRV can infect humans, causing severe viral encephalitis. People at risk of PRV infection should improve their self-protection awareness.

     

糖尿病黄斑水肿患者病变程度与脉络膜厚度的关系

目的　利用频域光学相干断层扫描深度增强（enhanced depth imaging spectral domain optical coherence tomography，EDI SD-OCT）观察糖尿病黄斑水肿（diabetic macular edema，DME）患者脉络膜厚度（choroidal thickness，CT）的变化及结构特点，探讨DME病变程度与CT的关系。方法　纳入2型糖尿病患者共123例204眼，其中69眼诊断为DME（DME组），135眼无黄斑水肿为对照组。DME眼依据OCT形态学特点进一步分为视网膜弥漫性增厚（diffuse retinal thickness，DRT）型（34眼）、黄斑囊样水肿（cystoid macular edema，CME）型（19眼）和浆液性视网膜脱离（serous retinal detachment，SRD）型（16眼），利用EDI-OCT分别测量黄斑中心凹下CT和以黄斑为中心上、下、鼻、颞500 μm、1000 μm、1500 μm、2000 μm处CT。结果　DME组黄斑中心凹下CT为（326.72±90.15）μm，对照组为（320.17±106.46）μm，两组之间无统计学差异，但黄斑中心凹下CT与视网膜厚度间具有明显正相关关系（r=0.270，P=0.025）。DME亚型CT分别为:DRT型（303.94±81.47）μm、CME型（304.42±73.98）μm和SRD型（401.63±88.80）μm，SRD型CT明显高于其他亚型（P<0.05），此外，SRD型的周边CT同样呈现均匀一致的增厚；鼻侧CT从500 μm至2000 μm呈距离敏感性降低（P<0.05），但SRD型鼻侧CT降低幅度明显变缓（P=0.195）。结论　SRD型黄斑水肿患者CT在中心凹下及周边部均显著增厚，CT与DME病变程度之间有一定相关性。

Objective: To observe the clinical effect of modified akupotomye closed lysis under CT guidance on compression of posterior lumbar nerve branch.Methods: Patients were diagnosed by HRCT 3-D reconstruction combined with clinical symptoms and signs.After HRCT three-dimensional reconstruction combined with clinical symptoms and signs, the patients were confirmed as posterior lumbar nerve compression.After CT accurate surface positioning, CT-guided modified akupotomye was used for closed lysis of the posterior lumbar nerve branch.Oswestry Dysfunction Index Questionnaire(ODI) was used for quantitative scoring, 7 days before and after treatment and 6 months after treatment.Results: In 62 cases, 20 cases were cured, with 25 cases markedly effective, 11 cases effective, and 36 cases ineffective.The total effective rate was 90.3%.ODI score: Self-paired t test 7 days before after treatment, P < 0.01;Before treatment and 6 months after treatment, self-paired t test(P < 0.01);Self-paired t-test was performed 7 days after treatment and 6 months after treatment(P > 0.05).Conclusion: With CT precise positioning, the modified akupotomye can be used to do closed lysis, to relieve the adhesion and compression, so that the low back pain can be relieved, with good clinical.The akupotomye closed lysis, combined with modern imaging technology has not only achieved good clinical effect, but also can improve the accuracy, safety and scientificity of akupotomye treatment.     

Severe lumbar spinal stenosis combined with Guillain-Barré syndrome: A case report

BACKGROUNDGuillain-Barré syndrome (GBS) is a rare disorder that typically presents with ascending weakness, pain, paraesthesias, and numbness, which mimic the findings in lumbar spinal stenosis. Here, we report a case of severe lumbar spinal stenosis combined with GBS.CASE SUMMARYA 70-year-old man with a history of lumbar spinal stenosis presented to our emergency department with severe lower back pain and lower extremity numbness. Magnetic resonance imaging confirmed the diagnosis of severe lumbar spinal stenosis. However, his symptoms did not improve postoperatively and he developed dysphagia and upper extremity numbness. An electromyogram was performed. Based on his symptoms, physical examination, and electromyogram, he was diagnosed with GBS. After 5 d of intravenous immunoglobulin (0.4 g/kg/d for 5 d) therapy, he gained 4/5 of strength in his upper and lower extremities and denied paraesthesias. He had regained 5/5 of strength in his extremities when he was discharged and had no symptoms during follow-up.CONCLUSIONGBS should be considered in the differential diagnosis of spinal disorder, even though magnetic resonance imaging shows severe lumbar spinal stenosis. This case highlights the importance of a careful diagnosis when a patient has a history of a disease and comes to the hospital with the same or similar symptoms.
