7Larger floods reduce soil CO_(2)efflux during the post-flooding phase in seasonally flooded forests of Western Amazonia显示文摘Seasonally flooded várzea forests of Western Amazonia are one of the most productive and biodiverse wetland forests in the world.However,data on their soil CO_(2)emissions,soil organic matter decomposition rates,and soil C stocks are scarce.This is a concern because hydrological changes are predicted to lead to increases in the height,extent,and duration of seasonal floods,which are likely to have a significant effect on soil C stocks and fluxes.However,with no empirical data,the impact of altered flood regimes on várzea soil C cycles remains uncertain.This study quantified the effects of maximum annual flood height and soil moisture on soil CO_(2)efflux rate(R_(s))and soil organic matter decomposition rate(k)in the várzea forests of Pacaya Samiria National Reserve,Peru.The study was conducted between May and August 2017.The results showed that R_(s)(10.6–182.7 mg C m^(-2)h^(-1))and k(0.016–0.078)varied between and within sites,and were considerably lower than the values reported for other tropical forests.In addition,R_(s)was negatively affected by flood height(P<0.01)and soil moisture(P<0.001),and it decreased with decreasing river levels post flooding(P<0.001).In contrast,k was not affected by any of the above-mentioned factors.Soil moisture was the dominant factor influencing R_(s),and it was significantly affected by maximum flood height,even after the floods had subsided(P<0.001).Consequently,we concluded that larger floods will likely lead to reduced R_(s),whilst k could remain unchanged but with decomposition processes becoming more anaerobic.Emma M.DOCHERTY Andrew D.THOMAS 2021Pedosphere2021,31,2:1

9超声心动图评价起搏模式及起搏部位对心脏再同步化治疗效果的影响显示文摘目的评价超声心动图在心力衰竭患者心脏再同步化治疗(cardiac resynchroni- zation therapy,CRT)中的应用价值,探讨起搏模式及起搏部位对其产生的影响。方法34例患者植入双室起搏器后随机进行4种不同模式起搏(双腔起搏(BiV),左室起搏(LV),右室起搏(RV)和不起搏、即窦性心律状态)。行常规超声心动图及二维彩色组织多普勒(Doppler tissue imaging, DTI)检查,测量射血分数(LVEF)、每搏输出量(SV)、节段心肌作功指数MPIr和每个节段心电图ORS波起始至该节段收缩达峰时间(Ts)。并比较左室电极放置在不同位置对心功能的影响。结果LV和BiV提高每搏输出量(P值均<0.02)和射血分数(P值均<0.01)。LV和BiV下左室节段MPIr改善(P值均<0。01),下壁和前壁基底段达峰时间差缩短(P值均<0.01)。电极放置在心脏侧后静脉或侧静脉时,SV、LVEF和Ts较后静脉或前静脉明显改善。结论LV和BiV可明显改善心力衰竭患者的心功能。超声心动图可无创伤性评价CRT治疗效果,并随访预后。程蕾蕾 孙静平 James D.Thomas 2007上海医学2007,30,S1:0
10组织多普勒和应变/应变率显像评价心力衰竭患者心脏再同步化治疗显示文摘目的评价超声心动图组织多普勒和应变/应变率在心力衰竭患者心脏再同步化治疗(cardiac resynchronization therapy,CRT)中的应用价值。方法34例患者植入双室起搏器后随机进行4种不同模式起搏(双腔起搏(BiV),左室起搏(LV),右室起搏(RV)和不起搏、即窦性心律状态)。行常规超声心动图及二维彩色组织多普勒(Doppler tissue imaging,DTI)检查,测量射血分数(LVEF)、每搏输出量(SV)、每个节段的心肌收缩速度峰值、节段心肌收缩位移、应变及应变率和每个节段心电图ORS波起始至该节段收缩达峰时间(TS)。并比较不同基础疾病导致的心力衰竭起搏后的改善情况。结果LV和BiV能提高每搏输出量(P值均<0.02)和射血分数(P值均<0.01);LV时左室节段心肌收缩位移明显改善:LV心尖段室间隔和侧壁收缩期应变率和应变改善;但BiV只有侧壁心尖段应变率明显改善。不同基础疾病起搏后心功能的改变差异无统计学意义。结论LV和BiV可明显改善心力衰竭患者的心功能。超声心动图DTI、应变/应变率可以无创伤性评价CRT治疗效果,并随访预后。程蕾蕾 孙静平 James D.Thomas 2007上海医学2007,0,S1:0
11曼氏血吸虫卵可溶性抗原基因克隆的研究显示文摘本文报导以曼氏血吸虫(Schistosoma mansoni)成虫mRNA为模板,通过逆转录酶促法合成cDNA。将虫源cDNA插入载体λgtll噬菌体基团组中编码β-半乳糖苷酶的LacZ基因区形成重组DNA,然后导入受体细胞E.coli KM392pmc9(lon^+)建立基因库,并从中筛选出若干株血吸虫抗原基因克隆。一株被兔抗虫卵可溶性抗原高免血清检获的基因克隆,其虫源基因片段经分子杂交证明系单拷贝基因。重组基因在溶原菌株中所表达的融合蛋白通过免疫印迹转移试验(EITB)证明与相关抗体具有很强的结合能力。DNA序列分析揭示该基因编码的多肽系由239个残基组成,其分子量理论推导值为28.7KD,化学性质呈强硷性和强亲水性。引人注意的是此多肽涟中含有一个由7个“精氨酸—甘氨酸”重复组成的结构独特片段。王云方 Wilde D.Thomas T.Doughty B.L.Kemp W.M. 1990畜牧兽医学报1990,21,2:0

13心脏淀粉样变性患者心功能变化的分析和研究显示文摘目的:应用超声心动图脉冲多普勒、组织多普勒(DTI)及彩色M型血流传播速率(Vp)技术评价心脏淀粉样变性患者的心脏功能。方法:对经心内膜活检证实并行超声心动图检查的74例心脏淀粉样变性患者的心脏功能变化进行分析,并根据心功能情况分收缩功能正常组和收缩功能减退组。结果:收缩功能减退组较收缩功能正常组二尖瓣E/A比值增高、DT缩短、Vp降低,并显示舒张期血流传播速度缓慢;DTI示E′及A′降低,反映充盈压升高的E/Vp和E/E'比值亦明显升高。所有患者均存在舒张功能障碍。结论:心脏淀粉样变性患者早期即出现舒张功能障碍,而收缩功能尚可维持正常。晚期则舒张和收缩功能均下降,并呈进行性发展。DTI和Vp技术可于早期对舒张功能障碍进行评价。林静娜 孙静平 王佩显 Allan L.Klein James D.Thomas 2006天津医药2006,34,6:0
14Knowledge of radiation exposure associated with common trauma imaging modalities among orthopaedic surgeons,emergency medicine physicians,and general surgeons in the United States显示文摘BACKGROUND:Few contemporary studies have assessed physicians’knowledge of radiation exposure associated with common imaging studies,especially in trauma care.The purpose of this study was to assess the knowledge of physicians involved in caring for trauma patients regarding the effective radiation doses of musculoskeletal(MSK)imaging studies routinely utilized in the trauma setting.METHODS:An electronic survey was distributed to United States orthopaedic surgery,general surgery,and emergency medicine(EM)residency programs.Participants were asked to estimate the radiation dose for common imaging modalities of the pelvis,lumbar spine,and lower extremity,in terms of chest X-ray(CXR)equivalents.Physician estimates were compared to the true effective radiation doses.Additionally,participants were asked to report the frequency of discussing radiation risk with patients.RESULTS:A total of 218 physicians completed the survey;102(46.8%)were EM physicians,88(40.4%)wereorthopaedicsurgeons,and28(12.8%)weregeneralsurgeons.Physicians underestimated the effective radiation doses of nearly all imaging modalities,most notably for pelvic computed tomaography(CT)(median 50 CXR estimation vs.162 CXR actual)and lumbar CT(median 50 CXR estimation vs.638 CXR actual).There was no difference between physician specialties regarding estimation accuracy(P=0.133).Physicians who regularly discussed radiation risks with patients more accurately estimated radiation exposure(P=0.007).CONCLUSION:The knowledge among orthopaedic and general surgeons and EM physicians regarding the radiation exposure associated with common MSK trauma imaging is lacking.Further investigation with larger scale studies is warranted,and additional education in this area may improve care.Fady Y.Hijji Andrew D.Schneider Matthew D.Thomas Joseph G.Lyons Daniel D.Bohl Jennifer L.Jerele Michael J.Prayson 2023World Journal of Emergency Medicine2023,14,4:0
