Ⅱ型固有淋巴样细胞在嗜酸性粒细胞性慢性鼻窦炎发病机制中的作用研究进展

慢性鼻窦炎(CRS)是一种常见的慢性非特异感染性鼻部疾病,病理分型主要分为Th2细胞介导的嗜酸性粒细胞性鼻窦炎(ECRS)和Th1细胞介导的非嗜酸性粒细胞性鼻窦炎(非ECRS)2种表型。欧洲国家CRS患病人群主要表现为ECRS,而随着亚洲国家的急剧工业化发展,其ECRS的比例也在急剧增加。ECRS发病机制复杂,涉及多种免疫细胞和相关因子相互作用。其治疗方法包括抗生素、激素药物治疗及手术治疗等,但仍有部分患者症状难以改善或存在复发的风险。Ⅱ型固有淋巴样细胞(ILC2s)是一种非B、非T的新型淋巴细胞,与Th2免疫应答关系密切。文章就ILC2s在ECRS发病机制中的作用进行综述,以期为ECRS的诊断和治疗提供理论参考。     

中医药治疗慢性前列腺炎研究概况

综述近年中医药治疗慢性前列腺炎的临床研究,认为本病病因病机之核心在于脾肾亏虚为本,湿热、痰浊、瘀毒为标,病久则伤及脾肾,由实转虚。中医内治法主要以辨证论治、辨病论治或单方验方为主,外治法以中药洗浴、中药灌肠、肛门给药、针灸为主。中医药治疗本病优势明显。应继续完善对中医药作用机制的认识,制订统一的辨证论治及疗效评价标准,针对效果显著的名方开展研究。     

Implementation of Recommendations for Long-Acting Contraception Among Women Aged 13 to 18 Years in Primary Care

ObjectiveClinical specialty societies recommend long-acting reversible contraceptives (LARCs) as first-line contraception for adolescent women. We evaluated whether a combined educational and process improvement intervention enhanced LARC placement in primary care within an integrated health care system.MethodsThe intervention included journal clubs, live continuing education, point-of-care guidelines, and new patient materials. We conducted a retrospective cohort study across 3 time periods: baseline (January 2013?September 2015), early implementation (October 2015–March 2016), and full implementation (April 2016–June 2017). The primary outcome was the proportion of LARCs placed by primary care clinicians among women aged 13 to 18 years compared with gynecology clinicians.ResultsKaiser Foundation Health Plan of Colorado cared for approximately 20,000 women aged 13 to 18 years in each calendar quarter between 2013 and 2017. Overall, LARC placement increased from 7.0 per 1000 members per quarter at baseline to 13.0 per 1000 during the full intervention. Primary care clinicians placed 6.2% of all LARCs in 2013, increasing to 32.1% by 2017 (P < .001), including 45.5% of contraceptive implants. Clinicians who attended educational sessions were more likely to adopt LARCs than those who did not (17.9% vs 6.4% respectively, P = .009). Neither overall LARC placement rates (relative risk, 1.9; 95% confidence interval, 0.7?5.6) nor contraceptive implant rates (relative risk, 3.0; 95% confidence interval, 0.9?9.8) increased significantly in clinicians who attended educational activities.ConclusionsThis multimodal intervention was associated with increased LARC placement for adolescent women in primary care. The combination of education and process improvement is a promising strategy to promote clinician behavior change.     

中医气郁质的研究进展

体质是在先天遗传和后天获得共同影响下形成的个体在形态结构和功能活动方面所固有的、相对稳定的特点,并且与心理性格具有相关性。其中气郁质的表现多与心理性格具有较大的相关性,同时由于当代社会的快速发展,各种危机和压力使年轻人成为气郁质的高发人群,因此探究气郁质的相关研究具有重大意义。本文通过对近些年来所发表的气郁质相关文献进行总结,重点从气郁质的人群分布调查研究、体病相关研究、调体干预研究以及实验室相关指标的研究四个方面进行分析阐述。最后对目前关于气郁质的研究中存在的优点和不足进行思考,并提出气郁质研究应在中医理论为指导的基础上,通过现代分子生物学实验或临床干预调体研究,揭示气郁质的本质和其量化诊疗标准,丰富气郁质的理论数据支持,促进中医体质学与多学科的交互发展。     

注射用肉毒毒素制剂及其研发进展

肉毒毒素(Botulinum Toxin,BoNT)已成为现代医学最具多用途的治疗药物之一。通过将肉毒毒素注射到特定过度活动的肌肉中,可以阻断神经和肌肉之间的信号传导,引起肌肉的松弛性麻痹,从而达到治疗的功效。从业者应熟悉各类产品的特性,以实现安全有效地使用。除了已经上市的众多肉毒毒素产品外,目前还在开发其他新型制剂,这些产品将会进一步扩大肉毒毒素的适用范围,以及给患者提供更多的选择。
