Out of the boxes,out of the silos: The need of interdisciplinary collaboration to reduce poor-quality medical products in the supply chain

In this paper, we argue that understanding and addressing the problem of poor-quality medical products requires a more interdisciplinary approach than has been evident to date. While prospective studies based on rigorous standardized methodologies are the gold standard for measuring the prevalence of poor-quality medical products and understanding their distribution nationally and internationally, they should be complemented by social science research to unpack the complex set of social, economic, and governance factors that underlie these patterns. In the following sections, we discuss specific examples of prospective quality surveys and of social science studies, highlighting the value of cross-sector partnerships in driving high-quality, policy-relevant research in this area.

Efficacy and safety of herbal medicines for idiopathic Parkinson's disease: a systematic review.

The objective of this study is to assess the efficacy and safety of herbal medicines (HMs), as a monotherapy or adjunct therapy, compared to placebo or conventional approaches in the treatment of idiopathic Parkinson's disease (PD). We conducted a systematic review of randomized controlled trials from both conventional and alternative medicine sources. Outcome measures were overall improvement, quality of life, reduction of levodopa dose, and adverse events. Nine studies were included, each testing a different HM. Six of the trials had limited internal validity due to major flaws in design, including the lack of proper randomization; insufficient blinding; unclear inclusive criteria in terms of diagnostic criteria, baseline staging, and duration of disease; lack of proper sample size calculation; and insufficient data analysis. Imbalances in gender and ethnicity among the patients in the included trials were observed. No major adverse events emerged, and no specific pattern was detected from the trials describing such data. In addition to major methodological defects, heterogeneity in (1) HM tested, (2) control treatment, and (3) outcome measure hindered in-depth data analysis and synthesis. Current evidence is insufficient to evaluate the efficacy and safety of various HMs. Further studies with improved trial design and reporting, with assessment on cost-effectiveness, quality of life, and qualitative data are warranted.     

15种生药提取物抑制痤疮致病菌的活性筛选

目的 :对 15种生药乙醇提取物的体外抑制痤疮致病菌活性进行敏感性测试。方法 :采用最大浓度抑菌试验和最低抑菌浓度 (MIC)比较其抑菌效果。结果 :丁香生药挥发油对痤疮致病菌痤疮短棒菌苗 (P .acne)、金黄色葡萄球菌 (S .aureus)、表皮葡萄球菌 (S .epidermidis)均有强烈的抑制作用 ,厚朴、艾叶油、金银花、蒲公英等有中等程度的抑菌作用。结论 :丁香酚的抑菌效果在所试药物中最好。     

白术茯苓汤及其配伍对脾虚大鼠胃肠激素的影响

目的：探讨益气健脾方剂治疗脾虚证的配伍规律。方法：采用苦寒泻下法复制大鼠脾虚模型，运用放射免疫分析法（RIA）检测白术茯苓汤及其与补气药。行气药及除湿药的不同配伍对脾虚大鼠胃泌素（GAS）、胃动素（MTL）及血管活性肠肽（VIP）的含量影响。结果：与正常对照组比较，脾虚模型大鼠GAS、MTL降低（P＜0．01），VIP升高（P＜0．01）；与自然恢复组比较，各治疗组以上部分或全部指标均有不同程度的改善，其中，以综合配伍组改善作用最优。结论：白术茯苓汤的脾虚大鼠胃肠激素的紊乱的某些指标，有一定的改善作用，综合配合组以上指标的改善，优于白术茯苓汤组及其余各配伍组，说明中医关于复方配伍的理论与实践，有其科学价值。     

50种传统清热解毒药的抑菌实验

本文报告了传统药物文献收载的５０种清热解毒药的抑菌实验结果。显示抑菌作用的有４１种，占８２％。对阳性球菌显示有抑菌作用的有３６种；对阴性杆菌显示有抑菌作用的有２４种。其中的地胡椒、金果榄、毛果算盘子等显示有较广的抗菌效应，值得进一步研究。     

中国南方六省各民族体质特征及相互关系的研究

应用多元分析法对中国南方２６个民族组的体质特征进行分析比较。南方中国人显示出面貌头型比例适中，但绝对值较小，身体较瘦小的基本特点。面部轮廓因子、头部形态因子和体型因子是区分他们体质特征的简便而主要的因素。     

人乳头瘤病毒与呼吸道肿瘤关系的研究：Ⅰ.HPV与喉癌的关系

应用α－３２Ｐ－ｄＣＴＰ标记ＨＰＶ－１１及ＨＰＶ－１６ＤＮＡ为探针，以Ｓｌｏｔｂｌｏｔ及Ｓｏｕｔｈｅｒｎｂｌｏｔ两种核酸杂交技术，检测了取自青岛及北京两个地区的３７例喉鳞癌组织ＤＮＡ中ＨＰＶ－１１及ＨＰＶ－１６ＤＮＡ相关序列。结果表明，Ｓｌｏｔｂｌｏｔ杂交中，与ＨＰＶ－１１探针杂交阳性者占８６％（３２／３７），与ＨＰＶ－１６探针杂交阳性者占８１％（３０／３７）。在同一癌组织中，与两型探针同时呈现阳性者占８１％（３０／３７）。Ｓｏｕｔｈｅｒｎｂｌｏｔ杂交中，与所用探针ＤＮＡ的内切酶ＰｓｔⅠ酶切图谱比较，有４６％（１３／２８）与ＨＰＶ－１６ＤＮＡ的酶切图谱相同，可定为ＨＰＶ－１６型。当用ＨＰＶ－１１探针时无一例出现与ＨＰＶ－１１相同的图谱。提示喉癌的发生与ＨＰＶ－１６有关。
