宣白承气汤单独用药及联合用药治疗肺炎痰热壅肺证Meta分析

目的:系统评价宣白承气汤单用及联合用药治疗肺炎痰热壅肺证的临床疗效。方法:检索CNKI、万方、CBM、PubMed等数据库,筛选宣白承气汤治疗肺炎的随机对照试验(RCT),运用Cochrane协作网偏倚风险评价工具进行文献质量评价,使用Revman 5.3 软件进行Meta分析。结果:最终纳入16项研究,共1393例患者,纳入文献质量不高。Meta分析结果表明,与单纯西医治疗相比,使用宣白承气汤可明显提高肺炎痰热壅肺证的临床总有效率[RR=1.29,95%,CI(1.22,1.36),P<0.00001],且亚组分析显示单用或联用宣白承气汤的组间差异无统计学意义; 可明显改善APACHE II评分、CPIS评分,明显降低炎症因子水平,改善中医证候积分。结论:宣白承气汤可有效治疗肺炎痰热壅肺证,但鉴于纳入临床研究在质量上存在一定局限性,得出的阳性结果仅作为临床诊疗的提示与参考,急需开展更多的高质量大规模的RCT来进一步验证。     

临床医学专业“5+3”一体化本科全程导师制创新人才培养的实践与探索

以培养创新型人才为目标，大连医科大学制定实施了“5+3”创新人才培养改革方案，以导师制培养为载体，在医学本科教育全过程中，制定分阶段创新能力培养体系，涵盖课程、讲座、实验设计、论文等基本科研能力训练，强化本科生科研能力培养。通过对首届“5+3”学生阶段性培养成果的统计学分析发现，“5+3”学生发表中文期刊、SCI，主持国家级创新项目、省级创新项目的比例均显著高于普通5年制学生，差异具有统计学意义（P<0.05）。虽然实施过程中存在一些问题和不足，但以导师制为核心的科研基础训练对提高学生科研思维和创新能力效果显著，对培养医学创新型人才具有可实施性。     

Impact of new technologies on diabetes care

Technologies for diabetes management, such as continuous subcutaneous insulin infusion (CSII) and continuous glucose monitoring (CGM) systems, have improved remarkably over the last decades. These developments are impacting the capacity to achieve recommended hemoglobin A1c levels and assisting in preventing the development and progression of micro- and macro vascular complications. While improvements in metabolic control and decreases in risk of severe and moderate hypoglycemia have been described with use of these technologies, large epidemiological international studies show that many patients are still unable to meet their glycemic goals, even when these technologies are used. This editorial will review the impact of technology on glycemic control, hypoglycemia and quality of life in children and youth with type 1 diabetes. Technologies reviewed include CSII, CGM systems and sensor-augmented insulin pumps. In addition, the usefulness of advanced functions such as bolus profiles, bolus calculators and threshold-suspend features will be also discussed. Moreover, the current editorial will explore the challenges of using these technologies. Indeed, despite the evidence currently available of the potential benefits of using advanced technologies in diabetes management, many patients still report barriers to using them. Finally this article will highlight the importance of future studies tailored toward overcome these barriers to optimizing glycemic control and avoiding severe hypoglycemia.     

螺旋断层治疗系统的质量保证

螺旋断层治疗系统(HT)是一种集调强放射治疗和影像引导放射治疗于一体的放射治疗系统,是目前最先进的放疗设备之一。考虑其与常规直线加速器质量保证的差异,由国家癌症中心/国家肿瘤质控中心提出,多家医疗单位共同参与制定了本指南。指南包括国内医疗机构HT用于临床工作的验收项目、操作制度、应急预案等内容,明确了质量控制的测试方法、评价标准、检测频率。指南结合国内医疗单位实际情况给出了推荐性检测项目,主要包括机械精度、剂量输出与分布、激光定位系统、治疗床运动精度、MVCT影像系统质控检测、临床治疗计划验证等具体实施方法步骤,使得指南具有很强的可操作性。本指南能给临床工作人员提供质量保证技术指导,使HT质量保证工作有章可循,可提高放射治疗的准确性和精度。对国内各医疗机构建立规范HT质量保证体系具有指导意义。     

Impulsive and compulsive behaviors in Parkinson's disease: Impact on quality of and satisfaction with life,and caregiver burden

IntroductionTo disentangle the association between impulsive and compulsive behaviors (ICBs), health-related quality of life (HRQOL), satisfaction with life (SwL), and caregiver distress in dyads of people with Parkinson's disease (PwP) and caregivers.MethodsData used in this study were obtained from the ongoing Norwegian ParkWest study, a population-based longitudinal cohort study of the incidence, neurobiology and prognosis of PD in Western Norway. One hundred and one dyads of PwP free of dementia and their caregivers were included 5 years after PD diagnosis and inclusion in the ParkWest study. Standardized clinical rating scales were used to evaluate ICBs, HRQOL, SwL and caregiver distress.ResultsOf 101 PwP-caregiver dyads, self-reported ICBs were seen in 33% of PwP and only caregiver-reported ICBs in 12% of PwP. PwP-reported ICBs were associated with poorer HRQOL and SwL, whereas ICBs reported by caregivers only were associated with increased caregiver distress, but not poorer HRQOL or SwL in PwP.ConclusionsICBs have adverse effects on HRQOL, SwL and caregiver distress. These findings underpin the need for proper identification and management of ICBs in PwP.     

吴茱萸化学成分和药理作用及质量标志物(Q-marker)的预测分析

吴茱萸是我国常用的大宗中药材,资源丰富且分布较广,具有广阔的开发利用前景。吴茱萸中化学成分类型丰富,包括生物碱、苦味素、挥发油、黄酮等类成分,传统认为生物碱和苦味素为其主要药效成分。对其化学成分、药理作用综述的基础上,根据中药质量标志物(Q-marker)理论,从生源途径、化学成分与传统功效、传统药性、新的临床用途、毒性、可测成分、入血成分及不同配伍环境几方面对吴茱萸Q-marker成分进行预测分析,为明确吴茱萸Q-marker和制定科学的质量标准提供基础。     

The relative risk of noncervical high-risk human papillomavirus-related (pre)malignancies after recurrent cervical intraepithelial neoplasia grade 3: A population-based study

Women with cervical intraepithelial neoplasia grade 3 (CIN3) have a long-lasting increased risk for noncervical high-risk human papillomavirus (hrHPV)-related (pre)malignancies. The aim of our study was to estimate this risk in women with recurrent CIN3 compared to women without a history of CIN3 and women with a single episode of CIN3. Women with a CIN3 diagnosis between 1990 and 2010 were obtained from the Dutch Pathology Registry (PALGA) and matched with a control group of women without CIN3. Analysis has been conducted in a subset of women with recurrent CIN3, defined as reoccurrence minimally 2 years post-treatment. Cases of noncervical hrHPV-related (pre)malignancies of the anus, vulva, vagina and oropharynx were identified until 2015 and incidence rate ratios (IRRs) were estimated. Then, 1,797 women with recurrent CIN3 were included with a median age of 34 years (range 18–76) and 31,594 person-years of follow-up. Women with recurrent CIN3 had an increased risk of developing noncervical hrHPV-related (pre)malignancies compared to women without CIN3 with an IRR of 25.96 (95%CI 6.32–106.58). The IRR was 2.48 (95% CI 1.87–3.30) compared to women with a single episode of CIN3. Studies on posttreatment follow-up and prophylactic hrHPV vaccination are warranted.
