间歇性断食联合多元化管理模式对超重及肥胖人群减重效果的研究

目的 探讨间歇性断食联合多元化管理模式对超重/肥胖人群的减重效果.方法 选择2019年1-12月首都医科大学附属北京潞河医院就诊的超重/肥胖患者110例,按照随机数字表法分为对照组和干预组,每组各55例.对照组实施常规间歇性断食模式,干预组实施间歇性断食联合多元化管理模式的减重干预,包括采用搭配营养膳食、合理运动、健康教育、互联网监测及心理疏导等综合手段.观察12周后两组的BMI、腰围、腰臀比、血脂、饥饿感、饱腹感、满足感的变化情况.结果 剔除退出、失访、不严格执行间歇性断食的患者,最终对照组和干预组各纳入52例患者,两组一般资料比较差异无统计学意义(P＞0.05).对照组和干预组干预前后各指标(体质量、腰围、腰臀比、BMI、血脂)及饥饿感、饱腹感、食物满足感比较,差异均有统计学意义(P＜0.05),且干预组改善效果优于对照组.结论 间歇性断食与多元化管理相结合,有效改善了减重患者的体质量、腰围、腰臀比、BMI、血脂各指标,增强食物饱腹感及满足感,减少饥饿感,提高了患者的减重依从性.     

纳米技术在嵌合抗原受体T细胞肿瘤免疫治疗中的应用进展

肿瘤免疫治疗主要通过解除免疫抑制作用与增强免疫应答反应来实现对其有效治疗.纳米技术能够提高免疫刺激分子的聚集度与作用力,在完成局部免疫调节的基础上有效治疗癌症.嵌合抗原受体T细胞(CAR-T)是肿瘤免疫治疗中的一种有力手段,能够对肿瘤患者的T细胞进行转化处理,令其成为可表达嵌合肿瘤细胞表面抗原受体的CAR-T细胞,随后将相应的CAR-T细胞回输至肿瘤患者体内,并通过特异性识别、杀伤肿瘤细胞的方式,有效杀灭肿瘤病毒.将纳米技术应用至CAR-T肿瘤免疫治疗中,有望提高肿瘤免疫治疗的疗效与安全性.本文就纳米技术在CAR-T肿瘤免疫治疗中的应用进展进行综述.     

Clinical therapeutic effects of probiotics in combination with antibiotics on periodontitis: A protocol for systematic review and meta-analysis

Background:Dental pain can have a detrimental effect on quality of life. Symptomatic apical periodontitis is the most common cause of dental pain and arise from an inflamed or necrotic dental pulp. There is growing evidence to support the effectiveness of probiotics in combination with antibiotics on periodontitis. We therefor will conduct this study to evaluate the clinical therapeutic effects of probiotics in combination with antibiotics on periodontitis.Methods:We will systematically search the following databases: PubMed, the Cochrane Library, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Chinese BioMedical Literature Database (CBM), and WanFang database. A grey literature search will be conducted using ZETOC Conference Proceedings and Open Grey. Only randomized controlled trials (RCTs) related to research on probiotics in combination with antibiotics to treatment patients with periodontitis will be included. All sources have to be searched from their inception to October 2020. Two authors will independently select studies, extract study data, and evaluate the quality of the included studies. We will use Review Manager Software (RevMan 5.3) to analyze data.Results:This study will systematically evaluate the clinical therapeutic effects of probiotics in combination with antibiotics on periodontitis.Conclusions:This study will generate evidence for a better clinical decision of patients with periodontitis.Registration number:DOI 10.17605/OSF.IO/QZ6SB (https://osf.io/qz6sb/).     

Surgical treatment of four segment lumbar spondylolysis: A case report

BACKGROUNDFour-level lumbar spondylolysis is extremely rare. So far, only 1 case has been reported in the literature. CASE SUMMARYA 19-year-old man presented with severe back pain irresponsive to conservative therapies for 2 years. Lumbar radiographs and two-dimensional computed tomography scan showed four segment lumbar spondylolysis on both sides of L2-L5. Lumbar magnetic resonance imaging showed normal signal in all lumbar discs. Because daily activities were severely limited, surgery was recommended for the case. The patient underwent four-level bilateral isthmic repair at L2-L5. During surgery, L2-L5 isthmi were curetted bilaterally, freshened, and then grafted with autologous iliac bone that was bridged and compressed with a pedicular screw connected to a sub-laminar hook by a short rod. The symptoms of back pain almost disappeared. He has been followed-up for 96 mo, and his symptoms have never recurred. Fusion was found in all repaired isthmi 14 mo after surgery according to evaluation of lumbar radiography and computed tomography scan.CONCLUSIONWe report here 1 case of four-level lumbar spondylolysis that was treated successfully with direct isthmic repair.
