Background Knowledge of the risk factors for complications following pancreaticoduodenectomy(PD) is sparse and there is not a consensus regarding the criteria to define the *** objective of this study was to determine the predictive risk factors for this surgery using the international study group *** Between October 1999 and September 2005,data from 295 consecutive patients who underwent a PD in the Eastern Hepatobiliary Surgery Hospital were recorded *** records and specific charts from surgical procedures,histopathology reports,and intens ve care units were continually *** logistic regression analyses were used to estimate relative risks and their 95%confidence *** Among 295 patients undergoing PD,103(34.9%) experienced at least one *** by low-volume surgeons(geries across their lifetime) were followed by more abdominal complications(odds ratio[OR]45.2).End-to-end pancreaticojejunostomy(PJ) resulted in more complications than end-to-side PJ(OR 2.7).Diabetes mellitus, increased estimated blood loss,and soft gland texture significantly increased the risks of abdominal complications. Systemic morbidity(OR 9.9) was the only independent predictive factor for *** High-volume surgeons and end-to-side PJ greatly reduce the risk of abdominal complications in patients undergoing *** higher abdominal complications rate in patients with soft gland texture was similar to those found in previous ***,PD should be performed with considerable attention in patients with diabetes mellitus.

Triplet surveys were conducted in the city of Xi'an and two villages (one in the vicinity and the other at a distance) in Shaanxi fuvince in China in October-November (when agricultural activitis were low), 1997, to elucidate nutrient intakes with a focus on possible urban-rural differences. Total food duplicate samples were collected from non-smoking and non-habitually dhnking adult healthy women (ahout 50 subjects per site and 149 in total). The nutrient intakes were estimated from the weight of food items in reference to national food composition tables. On average, the women took 1873 kcal energy, 54 g protein and 37 g lipid per day, with a lipid eneny ratio of 18.4%. Both excess and insufficient energy intake was observed as a result of food intake analysis and body mass index determination. With regard to minor nutrient intakes, insufficiency was serious in the case of calcium, vitamin A and vitamin B2, but not with iron. Whereas dependency on plant foods for sources of energy and protein was common to the three regions, Xi' an people consumed more animal foods than those in the villages. Intake of fish and shellfish was quite low throughout the three regions. Among the four types of cereals, wheat was consumed most substantially in the three regions and in three meals (except for the village where people essentially did not take lunch in reflection of low agricultural activities), whereas rice was consumed more in Xi'an than in the two villages. Maize consumption was higher in the two villages (especially for breakfast) than in the *** contrast, foxtail millet (although in small amounts) was taken primarily in Xi'an and ouly at the time of breakfast.

既有路径调整模型的研究载体是单模式网络,不能够刻画现实中多模式网络上出行者的路径调整行为.为此,本文提出采用比例延拓与绝对延拓两种方法来描述多模式网络中用户对不同出行方式的费用感知特性,并据此建立了多模式网络条件下的用户路径动态调整模型(Multi-modal Route-Swapping Dynamics,简称MRSD).研究发现:(1)MRSD能避免过度调整行为,并能维持解集不变性;(2)MRSD的稳定路径流模式与多模式网络用户均衡等价,且在其稳定状态,模式内部所有被使用的路径具有相同且最小的实际费用,模式之间所有被使用的路径之间存在(符合比例延拓或绝对延拓的)费用感知壁垒;(3)MRSD的所有解有界且收敛于多模式网络用户均衡.

1.2T装载机铲斗的结构简单相对耗材较多但装载物料较少,需要对其进行强度及疲劳寿命分析。其中装载机铲斗在工作过程中所承受的载荷历程是分析铲斗疲劳寿命的基础数据,装载机铲斗载荷历程的获取也一直是装载机研究领域的重点。为获取更贴近铲斗实际工作情况的载荷历程,采用散体力学与多体动力学耦合仿真的方式来获取铲斗的载荷历程。对1.2T铲斗进行应力应变实验,验证了载荷历程的准确性。最后利用得到的载荷历程对装载机铲斗进行强度与疲劳分析,发现了1.2T铲斗存在应力分布不合理现象,并计算得到其疲劳寿命。为1.2T铲斗结构的优化提供了参考,对其以后的优化、工程机械的计算与仿真有一定的指导意义。

目的探讨人造石英石作业人员的石英粉尘暴露对肺功能的影响。方法选取2017年9月至2018年3月,湖北省中西医结合医院职业病门诊及呼吸内科门诊就诊的46名男性石英石作业人员为暴露组,采用同期体检中心体检的41名健康男性为对照组。比较两组研究对象肺通气及弥散功能检查结果。结果暴露组工人肺活量(vital capacity,VC);用力肺活量(forced vital capacity,FVC);第1秒用力呼气量(forced expiratory volume at the first second of FVC,FEV1);最大呼气流速(peak expiratory flow,PEF)以及25%肺活量最大呼气流速(maximum expiratory flow at 25percent,MEF25%);50%肺活量最大呼气流速(maximum expiratory flow at 50percent,MEF50%);75%肺活量最大呼气流速(maximum expiratory flow at 75percent,MEF75%)的实测值占预计值百分率均低于对照组,差异有统计学意义(U=619.5、637.5、572.0、547.5、549.0、536.5、582.5,P=0.006、0.009、0.002、0.001、0.001、0.001、0.002)。两组间FEV1/FVC差异无统计学意义(U=732.0,P=0.073)。暴露组工人肺一氧化碳弥散量(diffusion capacity for carbon monoxide of the lung,DLCO)小于对照组,差异无统计学意义(U=825.5,P=0.318)。结论人造石英石粉尘的呼吸道暴露可导致工人肺通气功能明显下降,并以限制性通气功能障碍为主。
