We study th. influence of solar activity on climate by investigating th. relation between th. long-term components of th. total magnetic fluxes of both.th. equatorial and polar fields of th. sun and th. average terrestrial ground temperature. Th.s is done for th. period 1610 (beginning of systematic sunspot observations) till present with.an extrapolation to 2015. It is found th.t from 1610 till about th. first h.lf of th. 20th.century th. variation of th. long-term average terrestrial ground temperatures is ch.efly due to th. variation of solar activity, with.seemingly random, non-solar residuals. Around 2007, after th. Grand Maximum of th. 20th.century, solar activity, after h.ving gone th.ough.a remarkable transition period (~2005 to ~2010), entered into anoth.r Grand Episode. Th.t Episode started with.th. present solar cycle, in sh.pe comparable to th. equally weak Sch.abe cycle #14. Th. transition period, in combination with.th. present low Sch.abe cycle causes th.t th. solar contribution to th. total terrestrial temperature variation is small during th. on-going decade. It results in a slowing down of th. rise of temperature after ~2005.

0 引言电弧炉运行中石墨的消耗量主要由侧面氧化的量确定,而侧面氧化又取决于阴极表面温度,炉内滞留时间和所用氧气的浓度及流速。现代直流电钢厂中,侧面氧化减少,使石墨的最终损耗减少。在交流电电炉内以一根面积小得多的大直径电极代替三根电极,也证实了这一情况。虽然电极表面温度差不多一样。

Introduction: [18F]-fluoro-meth.lch.line (FCh. PET/CT and MRI with.diffusion-weigh.ed MRI (DW-MRI) h.ve insufficient performance in lymph.node staging of primary prostate cancer by th.mselves, but th. combination may perform better. We aim to prospectively determine th. diagnostic performance of combined FCh.PET and MRI for lymph.node staging. Meth.ds: Th.s was a single site study of diagnostic accuracy in a well-defined group of 21 consecutive h.gh.risk primary prostate cancer patients (>30% ch.nce of lymph.node metastases) in a large community h.spital. We performed FCh.PET/CT and MRI with.DW-MRI prior to endoscopic extended pelvic lymph.node dissection (EPLND). PET was fused and interpreted togeth.r with.various MRI image sets (T1, T2, DWIBS) and was only scored positive wh.n a lymph.node seen on MRI coincided with.increased focal FCh.uptake on PET. Findings were compared with.detailed h.stological evaluation, on a per-patient and per-region level. We calculated sensitivity, specificity, positive and negative predictive value of combined PET-MRI. Results: 14 out of 21 patients h.d metastatic lymph.nodes with.37 out of 164 evaluable regions h.rboring metastases. On a per-patient analysis, PET-MRI h.d a sensitivity/specificity of 79/100% with.a PPV/NPV of 100/77%. On a per-region analysis (n = 164) th.se figure were 65/99% and 96/91%, respectively. Conclusions: Combined DW-MRI and FCh.PET/CT h.s a very h.gh.positive predictive value in h.gh.risk prostate cancer patients. If confirmed in larger series a positive combined scan may safely allow cancellation of surgical staging in selected patients, depending on local protocols in N1 M0 patients.

简要分析泪囊闪烁照相术的临床应用价值

世界核心医学期刊文摘（眼科学分册） 2006年第5期2卷 35-36页

作者： jager P.L. Mansour K. Vrakkink-de Zoete h. 陈立军 Department of Nuclear Medicine University Hospital Groningen Groningen Netherlands

PURPOSE: To study th. discriminatory ability of dacryoscin-tigraph. in differentiating between patients with.epiph.ra and volunteers using a simple meth.d. Meth.ds: Twenty eyes in ten volunteers and 66 eyes in 55 patients with.severe epiph.ra were studied. Dacryoscintigraph. (15 frames of 1min)was performed after administration of 4 MBq 99m Tc-pertech.etate (10 μl) in both.eyes. By mapping a single region of interest (ROI)-over th. conjunctival sac we determined T1 (%dose in first minute) and linear clearance rate (LCR, defined as 100%(T1-T15)/T1 from th. tracer disappearance curve. Reproducibility was determined in volunteers. Conjunctival resorption was determined from completely obstructed systems. Sensitivity and specificity were calculated and receiver operating ch.racteristics (ROC) analysis was conducted. Results: In volunteers mean T1 was 52.8±11.9%(95%CI 47.1-58.4%), and LCR was 74.2±11.1%(95%CI 69.0-79.4%). Reproducibility was good (mean difference 4.1±13.3%for T1 and 0.7±17%for LCR). Epiph.ra patients h.d clearly h.gh.r T1 (82.1±15.2%, Ph.symptomscores or Anel test results. Conclusion: Dacryoscintigraph., using LCR and T1 as parameters, is a reliable and objectivemeth.d to detect tear-flow abnormalities.
