| 1 | Quantification of ventilation enhancement using the Eye CAN roof support显示文摘Convergence of roof and floor in underground mine openings is a common occurrence. This convergence not only adversely affects the ability of workers, equipment and supplies to travel through the mine, it also reduces the effectiveness of the mine ventilation system, which is essential for the dilution of methane gas and airborne respirable dust. While installing secondary standing supports to control floor and roof convergence, such supports, by nature, partially obstruct a portion of the airway. These added obstructions inhibit the ability of the ventilation system to operate as efficiently as it could by increasing the resistance in and reducing the cross-sectional area of the airway. This study introduces and demonstrates the benefits of The Eye CAN^(TM) standing roof support, which controls floor and roof convergence and is less obstructive to air flow than conventional wooden cribs. Laboratory findings show that the normal resistance of a supported lined airway is reduced by using this new product from Burrell Mining Products, Inc., while providing the same roof support characteristics of an established product—The CANò. Load vs. displacement curves generated from laboratory tests demonstrated that this new product behaves with the same roof support characteristics as others in The CAN product family. Ventilation data gathered from a simulated mine entry was then used for computational fluid dynamics(CFD) modeling.The CFD analysis showed an improvement with The Eye CAN vs. other accepted forms of standing roof support. This proof-of-concept study suggests that, when using this new product made by Burrell Mining Products, Inc., not only will the convergence from the roof and floor be controlled, but airway resistance will also be reduced. | Shook Michael T Sindelar Mark F, Jiang Hua Luo Yi | 2017 | International Journal of Mining Science and Technology2017，27，1： | 3 |
| 2 | Strong prognostic value of nodal and bone marrow micro-involvement in patients with pancreatic ductal carcinoma receiving no adjuvant chemotherapy显示文摘AIM: To study the prognostic value of adjuvant chemo-therapy in patients with pancreatic, ductal adenocar-cinoma.METHODS: Lymph nodes from 106 patients with resectable pancreatic ductal adenocarcinoma were systematically sampled. A total of 318 lymph nodes classified histopathologically as tumor-free were examined using sensitive immunohistochemical assays. Forty-three (41%) of the 106 patients were staged as pT1/2, 63 (59%) as pT3/4, 51 (48%) as pN0, and 55 (52%) as pN1. The study population included 59 (56%) patients exhibiting G1/2, and 47 (44%) patients with G3 tumors. Patients received no adjuvant chemo- or radiation therapy and were followed up for a median of 12 (range: 3.5 to 139) mo.RESULTS: Immunostaining with Ber-EP4 revealed nodal microinvolvement in lymph nodes classified as “tumor free” by conventional histopathology in 73 (69%) out of the 106 patients. Twenty-nine (57%)of 51 patients staged histopathologically as pN0 had nodal microinvolvement. The five-year survival probability for pN0-patients was 54% for those without nodal microinvolvement and 0% for those with nodal microinvolvement. Cox-regression modeling revealed the independent prognostic effect of nodal microinvolvement on recurrence-free (relative risk 2.92, P = 0.005) and overall (relative risk 2.49, P = 0.009) survival.CONCLUSION: The study reveals strong and independent prognostic significance of nodal microinvolvement in patients with pancreatic ductal adenocarcinoma who have received no adjuvant therapy. The addition of immunohistochemical findings to histopathology reports may help to improve risk stratification of patients with pancreatic cancer. | Emre F Yekebas Dean Bogoevski Michael Bubenheim Bjrn-Christian Link Jussuf T Kaifi Robin Wachowiak Oliver Mann Asad Kutup Guellue Cataldegirmen Lars Wolfram Andreas Erbersdobler Christoph Klein Klaus Pantel Jakob R Izbicki | 2006 | World Journal of Gastroenterology2006，12，40： | 3 |

| 4 | 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 |
| 5 | Association between population vitamin D status and SARS-CoV-2 related serious-critical illness and deaths:An ecological integrative approach显示文摘BACKGROUND Vitamin D population status may have possible unappreciated consequences to the coronavirus disease 2019(COVID-19)pandemic.Αsignificant association between vitamin D sufficiency and reduction in clinical severity and inpatient mortality from COVID-19 disease has recently been shown,while a recent study has claimed lower COVID-19 cases in European countries with a better vitamin D status.Low serum 25-hydroxyvitamin-D[25(OH)D]was identified as an independent risk factor for COVID-19 infection and hospitalization,and administration of 0.532 mg(21280 IU)of calcifediol or 25(OH)D,followed by 0.266 mg on days 3 and 7 and then weekly until discharge or intensive care unit admission significantly reduced the need for intensive care unit treatment.AIM To elucidate the role of vitamin D European population status in the COVID-19 pandemic,data from the Worldometer were analyzed.METHODS Linear regression explored the correlation between published representativestandardized population vitamin D concentrations and the number of total cases/million(M),recovered/M,deaths/M and serious-critically ill/M from COVID-19 for 26 European countries populated>4 M(Worldometer).Life expectancy was analyzed with semi-parametric regression.Weighted analysis of variance/analysis of covariance evaluated serious-critical/M and deaths/M by the vitamin D population status:Deficient<50,insufficient:50-62.5,mildly insufficient>62.5-75 and sufficient>75 nmol/L,while controlling for life expectancy for deaths/M.Statistical analyses were performed in XLSTAT LIFE SCIENCE and R(SemiPar Library).RESULTS Linear regression found no correlation between population vitamin D concentrations and the total cases-recovered/M,but negative correlations predicting a reduction of 47%-64%-80%in serious-critical illnesses/M and of 61%-82%-102.4%in deaths/M further enhanced when adapting for life expectancy by 133-177-221%if 25(OH)D concentrations reach 100-125-150 nmol/L,sustained on August 15,2020,indicating a truthful association.Weighted analysis of variance was performed to evaluate serious-critical/M(r2=0.22)by the vitamin D population status and analysis of covariance the deaths/M(r2=0.629)controlling for life expectancy(r2=0.47).Serious-critical showed a decreasing trend(P<0.001)from population status deficient(P<0.001)to insufficient by 9.2%(P<0.001),to mildly insufficient by 47.6%(P<0.044)and to sufficient by 100%(reference,P<0.001).For deaths/M the respective decreasing trend(P<0.001)was 62.9%from deficient(P<0.001)to insufficient(P<0.001),65.15%to mildly insufficient(P<0.001)and 78.8%to sufficient(P=0.041).CONCLUSION Achieving serum 25(OH)D 100-150 nmol/L(40-60 ng/mL)(upper tolerable daily doses followed by maintenance proposed doses not requiring medical supervision,Endocrine Society)may protect from serious-critical illness/death from COVID-19 disease. | Dimitrios T Papadimitriou Alexandros K Vassaras Michael F Holick | 2021 | World Journal of Virology2021，10，3： | 2 |
