| 1 | QUADAS的制定:用于系统评价中评价诊断性研究质量的工具显示文摘背景在以系统评价为基石的循证医学时代,需要有恰当的质量评价工具。对诊断性研究的评价目前尚缺乏系统开发且经过验证的评价工具。本研究的目的是采用共识决策法整合经验证据和专家意见,制定在系统评价时用于评价原始诊断性研究质量的工具。方法按照循证原则,我们在之前发表的3篇诊断性研究文献的综述的基础上,初选出一些条目形成列表,然后通过Delphi流程逐步调整列表,形成质量评价工具。参与Delphi流程的都是诊断性研究领域的专家。结果共有9位诊断学领域的专家参与Delphi流程。经过4轮Delphi流程后,专家们对哪些条目应纳入评价工具达成共识,我们把这个评价工具命名为QUADAS。纳入条目从最初的28个减少到14个,涵盖了疾病谱、金标准、疾病进展偏倚(disease progression bias)、证实偏倚(verification bias)、评价偏倚、临床评价偏倚、合并偏倚、试验的实施、病例退出以及不确定结果。QUADAS工具中的每个条目都配有评分细则。结论本研究项目开发出了用于诊断性试验系统评价的循证质量评价工具。下一步工作是确定其适用性和有效性。 | Penny Whiting Anne WS Rutjes Johannes B Reitsma Patrick MM Bossuyt Jos Kleijnen 刁骧(译) 艾昌林(译) 秦莉(审校) 姚巡(审校) | 2007 | 中国循证医学杂志2007，7，4： | 67 |
| 2 | QUADAS评价:一种用于诊断性研究的质量评价工具(修订版)显示文摘背景 QUADAS是一种新近发展起来的诊断性研究的质量评价工具。虽然已有系统评价采用了QUADAS,但尚未得以正式确证。本研究的目的是评价QUADAS的有效性和实用性。方法3位评价者采用QUADAS独立评价30项研究的质量。比较每位评价者的评分与最终结论之间的意见一致度。这主要是通过比较所有QUADAS条目的总分和每个单项的得分来实现的。20位曾在其系统评价中使用过QUADAS的评价者就其使用经验完成一份简短的问卷。结果就所有条目而言,每位评价者的评分与最终结论之间的意见一致度分别达到了91%、90%和85%。就单项QUADAS条目而言,一致度在50%至100%之间,中位值是90%。与难以解释的试验结果和退出病例相关的条目,评分结果差异最大。有关QUADAS内容的反馈意见普遍较好,仅少数评价者提出了有关QUADAS涵盖面、使用便利性、评分说明的清晰度及有效性方面的问题。结论QUADAS内容本身无需作大的修改。评价过程的主要困难出现在难以解释的试验结果和退出病例这2个条目的评分上。对这些条目的评分指南提出了修改意见。评价者必需根据其系统评价制定相应的评分指南,并确保所有评价者都清楚如何评分。评价者还应考虑是否所有的QUADAS条目都与其系统评价相关,以及其他质量条目是否应作为其系统评价的评价部分。 | Penny F Whiting Marie E Weswood Anne WS Rutjes Johannes B Reitsma Patrick NM Bossuyt Jos Kleijnen 马章淳 钱楠 | 2007 | 中国循证医学杂志2007，7，7： | 64 |
| 3 | Adipose-derived stromal cells: Their identity and uses in clinical trials, an update显示文摘In adults, adipose tissue is abundant and can be easily sampled using liposuction. Largely involved in obesity and associated metabolic disorders, it is now described as a reservoir of immature stromal cells. These cells, called adipose-derived stromal cells (ADSCs) must be distinguished from the crude stromal vascular fraction (SVF) obtained after digestion of adipose tissue. ADSCs share many features with mesenchymal stem cells derived from bone marrow, including paracrine activity, but they also display some specific features, including a greater angiogenic potential. Their angiogenic properties as well as their paracrine activity suggest a putative tumor-promoting role for ADSCs although contradictory data have been published on this issue. Both SVF cells and ADSCs are currently being investigated in clinical trials in several fields (chronic inflammation, ischemic diseases, etc. ). Apart from a phase Ⅲ trial on the treatment of fistula,most of these are in phaseⅠand use autologous cells. In the near future, the end results of these trials should provide a great deal of data on the safety of ADSC use. | Louis Casteilla Valérie Planat-Benard Patrick Laharrague Béatrice Cousin | 2011 | World Journal of Stem Cells2011，3，4： | 31 |

| 5 | 直接评估吗啡刺激糖尿病人隐静脉内皮一氧化氮释放减少显示文摘to directly measure in real time basal and stimulated levels of NO released from human saphenous vein endothelium and to quantify the expression of the μopiate receptor, which has been linked with NO release. METHODS: Saphenous vein segments from patients with type 2 diabetes ( n = 12) and patients without diabetes (n =8) were obtained. The release of NO was measured directly from the endothelium using a NO-specific amperometric probe. NΩ-nitro-L-arginine methyl ester (L-NAME, 0.1 mmol/L), a NO synthase (NOS) inhibitor, or morphine (1 μmol/L), a stimulant, was administered and the measurements were repeated. Values were reported relative to the mean initial measurement of NO release from diabetic endothelium, which was defined as the relative zero level of NO release. A RT-PCR was then performed on the endothelium to measureμ opiate receptor expression. RESULTS: Diabetic patients (n = 12) showed a relative and significantly diminished basal level of released NO, (0.049± 0.012) nmol/L, compared | Thomas V BILHNGER, James A VOSSWINKEL, Patrick CADET, Christos M RIALAS, Harold I MAGAZINE, George B STEFANO(Division of Cardiothoracic Surgery, Department of Surgery, University Hospital and Medical Center, HSC, T19-080, Stony Brook, New York 11794-8191 Neuroscience Research Institute, State University of New York College at Old Westbury, Old Westbury, New York , USA) | 2002 | Acta Pharmacologica Sinica2002，23，2： | 3 |
| 6 | Secondary angiodysplasia-associated gastrointestinal bleeding in end-stage renal disease: Results from the nationwide inpatient sample显示文摘BACKGROUND Chronic kidney disease is associated with angiodysplasia of gastrointestinal tract leading to increased risk of gastrointestinal bleeding.AIM To determine the nationwide prevalence,trends,predictors and resource utilization of angiodysplasia-associated gastrointestinal bleeding in end-stage renal disease hospitalizations.METHODS The Nationwide Inpatient Sample database from 2009 to 2014,was utilized to conduct a retrospective study on patients with angiodysplasia associatedgastrointestinal bleeding and end-stage renal disease.Hospitalizations with endstage renal disease were included in the Nationwide Inpatient Sample database and a subset of hospitalizations with end-stage renal disease and angiodysplasiaassociated gastrointestinal bleeding were identified with International Classification of Diseases,9th revision,Clinical Modification codes for both endstage renal disease(585.6)and angiodysplasia(569.85,537.83).RESULTS The prevalence of angiodysplasia-associated gastrointestinal bleeding was 0.45%(n=24709)among all end-stage renal disease patients(n=5505252)that were hospitalized.Multivariate analysis indicated that the following were significant factors associated with higher odds of angiodysplasia associated-gastrointestinal bleeding in end-stage renal disease patients:an increasing trend from 2009-2014(P<0.01),increasing age(P<0.0001);African American race(P=0.0206);increasing Charlson-Deyo Comorbidity Index(P<0.01);hypertension(P<0.0001);and tobacco use(P<0.0001).Diabetes mellitus(P<0.0001)was associated with lower odds of angiodysplasia associated-gastrointestinal bleeding in end-stage renal disease patients.In comparison with urban teaching hospitals,rural and urban nonteaching hospitals were associated with decreased odds of angiodysplasia associated-gastrointestinal hemorrhage.CONCLUSION Angiodysplasia-associated gastrointestinal bleeding in end-stage renal disease patients showed an increasing trend from 2009-2014.Advanced age,African American race,overall high comorbidities,hypertension and smoking were significant factors for angiodysplasia-associated gastrointestinal bleeding in bleeding in these patients. | Tooba Tariq Patrick Karabon Furqan B Irfan Sachin Goyal Matthew Masaru Mayeda Austin Parsons Stephanie Judd Murray Ehrinpreis | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，10： | 3 |
| 7 | Reduced anoctamin 7(ANO7) expression is a strong and independent predictor of poor prognosis in prostate cancer显示文摘Objective:Anoctamin 7(ANO7)is a calcium2+-dependent chloride ion channel protein.Its expression is restricted to prostate epithelial cells.The exact function is unknown.This study aimed to analyze ANO7 expression and its clinical significance in prostate cancer(PCa).Methods:ANO7 expression was assessed by immunohistochemistry in 17,747 clinical PCa specimens.Results:ANO7 was strongly expressed in normal prostate glandular cells but often less abundant in cancer cells.ANO7 staining was interpretable in 13,594 cancer tissues and considered strong in 34.4%,moderate in 48.7%,weak in 9.3%,and negative in 7.6%.Reduced staining was tightly linked to adverse tumor features[high classical and quantitative Gleason grade,lymph node metastasis,advanced tumor stage,high Ki67 labeling index,positive surgical margin,and early biochemical recurrence(P<0.0001 each)].The univariate Cox hazard ratio for prostate-specific antigen(PSA)recurrence after prostatectomy in patients with negative vs.strong ANO7 expression was 2.98(95%confidence interval 2.61–3.38).The prognostic impact was independent of established pre-or postoperatively available parameters(P<0.0001).Analysis of annotated molecular data showed that low ANO7 expression was linked to TMPRSS2:ERG fusions(P<0.0001),elevated androgen receptor expression(P<0.0001),as well as presence of 9 of 11 chromosomal deletions(P<0.05 each).A particularly strong association of low ANO7 expression with phosphatase and tensin homolog(PTEN)deletion may indicate a functional relationship with the PTEN/AKT pathway.Conclusions:These data identify reduced ANO7 protein expression as a strong and independent predictor of poor prognosis in PCa.ANO7 measurement,either alone or in combination,might provide clinically useful prognostic information in PCa. | Andreas Marx Lena Koopmann Doris Hoflmayer Franziska Büscheck Claudia Hube-Magg Stefan Steurer Till Eichenauer Till S.Clauditz Waldemar Wilczak Ronald Simon Guido Sauter Jakob R.Izbicki Hartwig Huland Hans Heinzer Markus Graefen Alexander Haese Thorsten Schlomm Christian Bernreuther Patrick Lebok Sarah Bonk | 2021 | Cancer Biology & Medicine2021，18，1： | 3 |
| 8 | 一种房颤风险评分系统的建立(Framingham心脏研究):基于社区的队列研究显示文摘背景房颤导致了发病率和病死率的显著上升。本研究旨在建立一种预测个体罹患房颤绝对风险的风险评分系统,并提供研究人员评价新危险因素的流程。方法作者评估了Framingham心脏研究中于1968年6月至1987年9月间进行了8044次检测的4764例参与者(55%为女性,年龄45~95岁)。此后,参与者被随访至房颤首发,随访期最长达10年。多变量Coxi回归确认出1(1年内罹患房颤的临床危险因素。次级分析纳入了常规超声心动图检测指标(5152例4参与者,7156次检测)对房颤风险进行再分层评估,并评价超声检测指标能否提高风险预测能力。结果4764例参与者中的457例4(10%)罹患房颤。年龄、性别、体重指数、收缩压、降压治疗、PR间期、有临床意义的心脏杂音及心力衰竭与房颤相关,并被纳入了风险评分模型(除体重指数P=0.08外,其余均为P〈0.05),模型的C统计量为0.78(95%CI0.76~0.80)。10年房颤风险随年龄变化:年龄〈65岁的人群中53例(1%)风险高于15%,而〉65岁的人群中为783例(27%)。为提高预测能力而纳入超声检测指标仅使模型C统计量略微增高,由0.78(95%C10.75~0.80)增至0.79(95%CI0.77~0.82:P=0.005)。超声心动图检测指标并不能改善风险再分层评估(P=0.18)。结论基于社区医疗中易得的临床因素建立的风险评分系统,有助于确认社区个体罹患房颤的风险,评估技术或标志物能否改善风险预测,以及针对高危个体采取预防措施。 | Renate B Schnabel Lisa M Sullivan Daniel Levy Michael J Pencina Joseph M Massaro Ralph B D'Agostino Sr Christopher Newton-Cheh Jennifer F Yamamoto Jared W Magnani Thomas M Tadros William B Kannel Thomas J Wang Patrick T Ellinor Philip A Wolf Ramachanclran S Vasan Emelia J Benjamin 黄刚(译) | 2009 | 世界临床医学2009，，9： | 2 |
