Imaging Features of Pulmonary Immune-related Adverse Events

Pulmonary immune-related adverse events represent rare but potentially severe side effects of immunotherapies. Diagnosis is often challenging, as symptoms and imaging features are not specific and may mimic other lung diseases, thus potentially delaying appropriate patient management. In this setting, an accurate imaging evaluation is essential for a prompt detection and correct management of these drug-induced lung diseases. The purpose of this article is to review the different types of pulmonary immune-related adverse events, describe their imaging characteristics on both high-resolution computed tomography and positron emission tomography/computed tomography and stress their underlying diagnostic challenge by presenting the mimickers.     

The Relationship between College Graduate’s Dual Self-Consciousness and Job Search Clarity: The Mediating Role of Perceived Stress

The aim of the study was to explore the relationship between college graduates’ dual self-consciousness, job search clarity and perceived stress, and reveal the mediating role of perceived stress between dual self-consciousness and job search clarity. In this study, 467 college graduates were investigated using the Dual Self-Consciousness Scale, Job Search Clarity Scale, and Perceived Stress Scale. After controlling for gender, age, and region, the results revealed that: (1) private self-consciousness has a significant positive predictive effect on job search clarity; (2) perceived stress has a significant negative predictive effect on job search clarity; (3) perceived stress plays partial mediation effects between private self-consciousness and job search clarity; (4) perceived stress plays complete mediation effects between public self-consciousness and job search clarity; (5) perceived stress has suppressing effects between public self-consciousness and job search clarity.     

Optimizing Prescribing and Deprescribing of Proton Pump Inhibitors

Prescribing of proton pump inhibitors (PPIs) has markedly increased since their inception more than 30 years ago. The increase is related to inappropriate and long-term prescribing of PPIs, associated with a lack of education and unclear prescribing and deprescribing guidelines. The implementation of prescribing stewardship programs influences the reduction and inappropriate use of this medication. The purpose of this review is to address the gaps that exist regarding the use of PPIs along with determining methods for deprescribing. Guidelines and stewardship programs, along with education, are needed to reduce the adverse health effects of long-term PPI therapy.     

针刀配合针灸治疗腰椎间盘突出症的临床疗效观察

目的:分析针刀与针灸配合应用于腰椎间盘突出症患者中的临床治疗效果。方法:在我院针灸康复科2017年12月-2018年12月治疗的腰椎间盘突出症患者中选取64例,并严格按照系统随机分配原则分为对照组和观察组,各32例。其中对照组采用针灸进行治疗,观察组采用针刀与针灸配合治疗,观察对比两组患者治疗后临床效果和治疗前后运动功能评分(Fugl-Meyer)、腰椎日本骨科学会(Japanese Orthopaedic Association,JOA)评分、视觉模拟评分法(Visual Analogue Scale,VAS)评分以及临床症状改善情况。结果:两组患者治疗前Fugl-Meyer、VAS、JOA评分差异无统计学意义(P>0.05),治疗后对照组VAS评分高于观察组,Fugl-Meyer、JOA评分低于观察组,且对照组总有效率低于观察组,对照组腰骶疼痛评分和腿疼痛评分均低于观察组,直腿抬高度高于观察组,差异具有统计学意义(P<0.05)。结论:予以腰椎间盘突出症患者针刀与针灸配合治疗效果显著,效果优于单一使用针灸治疗,可有效缓解患者疼痛感,改善临床症状,值得推广。     

磁共振质子波谱成像(1H-MRSI) 在胶质瘤诊断中的应用

目的探讨利用磁共振波谱成像(MRSI)反映胶质瘤恶性度的价值.方法41例病理证实胶质瘤,原发39例、复发2例,行MR及MRS扫描,MRS数据经残差Z分数统计模型及LLI、Lip/Cho等指标划分肿瘤边界及不同代谢区,并结合MRI结构成像,划分出肿瘤的高代谢活性区、肿瘤浸润边界、坏死区及乏氧区.结果肿瘤浸润边界均超过MR常规图像上的肿瘤边界.Ⅱ级肿瘤高代谢活性区大部分位于肿瘤区内,但Ⅲ、Ⅳ级则大部分位于肿瘤边界;随肿瘤恶性度升高,肿瘤出现了坏死区及乏氧区.结论MRSI对确定肿瘤恶性度及划分肿瘤边界具有一定价值.

急性脑梗死血清C-反应蛋白的临床分析

目的观察急性脑梗死患者血清CRP在发病中的作用及临床意义。方法采用免疫比浊法对60例急性脑梗死患者的血清CRP水平进行动态观察（病程第1．7及14天），并与45例健康人进行比较。结果急性脑梗死患者血清CRP从病程第1天即升高（P〈0．01），至第7天达高峰，以后降低；重型患者明显高于轻、中型患者。结论血清CRP可能在急性脑梗死的发生、发展中起一定作用，并与病情严重程度呈正相关。     

北京地区rt-PA静脉溶栓治疗超早期脑梗死患者临床分析

目的分析北京地区12所医院202例超早期脑梗死患者经不同剂量重组组织型纤溶酶原激活剂(rt- PA)静脉溶栓治疗后的疗效及其不良事件,探讨使用rt-PA的最佳剂量及其安全性与可行性。方法287例发病6h以内的脑梗死患者,男201例,女86例,年龄38～80岁,平均64岁。所有患者均伴有偏瘫,头颅CT未见出血及责任梗死灶,无溶栓禁忌证。202例接受rt-PA治疗,分为A组与B组,A组88例,给予rt-PA 0．9 mg/kg。B组114例,给予rt- PA0．6～0．8 mg/kg。C组(对照组)85例患者给予低分子右旋糖酐、复方丹参等治疗。分别比较治疗前与治疗后11d、21 d、90 d的美国国立卫生院神经功能缺损评分(NIHSS)、Barthel指数,并进行疗效评定。结果A组、B组分别与C组90 d的NIHSS评分、Barthel指数相比有显著差异。A组、B组及C组的基本痊愈及显著改善率分别为69%、77%及40%．A组、B组分别与C组脑出血的发生率为7．96%、4．38%及0%。症状性出血(4．55%、2．63%及0%),非症状性出血(2．63%、1．75%及0%)。结论超早期脑梗死静脉应用rt-PA溶栓治疗是安全有效的。不同剂量的rt-PA均减轻了脑梗死的致残率,但两组间无明显差异。中国人rt-PA溶栓治疗最佳剂量尚需要进一步进行大样本的前瞻性、多中心、随机对照研究．
