AIM: To analyze and compare postoperative morbidity between patients receiving total parenteral nutrition (TPN) and early enteral nutrition supplemented with parenteral nutrition (EEN + PN).METHODS: Three hundred and forty patients receiving pancreaticoduodenectomy (PD) from 2009 to 2013 at our center were enrolled retrospectively. Patients were divided into two groups depending on postoperative nutrition support scheme: an EEN + PN group (n = 87) and a TPN group (n = 253). Demographic characteristics, comorbidities, preoperative biochemical parameters, pathological diagnosis, intraoperative information, and postoperative complications of the two groups were ***: The two groups did not differ in demographic characteristics, preoperative comorbidities, preoperative biochemical parameters or pathological findings (P > 0.05 for all). However, patients with EEN + PN following PD had a higher incidence of delayed gastric emptying (16.1% vs 6.7%, P = 0.016), pulmonary infection (10.3% vs 3.6%, P = 0.024), and probably intraperitoneal infection (18.4% vs 10.3%, P = 0.059), which might account for their longer nasogastric tube retention time (9 d vs 5 d, P = 0.006), postoperative hospital stay (25 d vs 20 d, P = 0.055) and higher hospitalization expenses (USD10397 vs USD8663.9, P = 0.008), compared to those with ***: Our study suggests that TPN might be safe and sufficient for patient recovery after PD. Postoperative EEN should only be performed scrupulously and selectively.

AIM: To investigate the capability of multidetector CT (MDCT) to diagnose HCC-associated arterioportal shunt (APS).METHODS: Two hundred and eighty-two patients with HCC received both thin-slice and enhancement MDCT scanning at early hepatic arterial phase, late hepatic arterial phase and portal venous phase, and digital subtract angiography (DSA) examination. Images were analyzed jointly by two experienced radiologists blinded to the opposite examination results, including the existence or not of APS, shunt locations, types and degrees of APS, with or without thrombosis. RESULTS: There were 56 APS associated with HCC, including 48 central, seven peripheral and one mixed, or 42 severe, seven moderate, seven mild APS. Fortyone severe, seven moderate and central APS were all revealed with MDCT and DSA. Seven mild and peripheral APS were all displayed with MDCT; only five of them displayed DSA, two faint shunt APS associated with massive HCC were missed. One mixed APS was demonstrated as severe combined with mild shunt with both MDCT and ***: MDCT could diagnose not only DSA revealed APS, but also missed mild and peripheral APS with DSA due to faint shunt associated with massive HCC, is a simple, effective and noninvasive new technique for diagnosis of HCC-associated APS.

AIM: To investigate the optimal magnetic pressure and provide a theoretical basis for choledochojejunostomy magnetic compressive anastomosis(magnamosis).METHODS: Four groups of neodymium-iron-boron magnets with different magnetic pressures of 0.1, 0.2, 0.3 and 0.4 MPa were used to complete the choledochojejunostomy magnamosis. Twenty-six young mongrel dogs were randomly divided into five groups: four groups with different magnetic pressures and 1 group with a hand-suture anastomosis. Serum bilirubin levels were measured in all groups before and 1 wk, 2 wk, 3 wk, 1 mo and 3 mo after surgery. Daily abdominal X-ray fluoroscopy was carried out postoperatively to detect the path and the excretion of the magnet. The animals were euthanized at 1 or 3 mo after the operation, the burst pressure was detected in each anastomosis, and the gross appearance and histology were compared according to the ***: The surgical procedures were all successfully performed in animals. However, animals of group D(magnetic pressure of 0.4 MPa) all experienced complications with bile leakage(4/4), whereas half of animals in group A(magnetic pressure of 0.1 MPa) experienced complications(3/6), 1 animal in the manual group E developed anastomotic stenosis, and animals in group B and group C(magnetic pressure of 0.2 MPa and 0.3 MPa, respectively) all healed well without complications. These results also suggested that the time required to form the stoma was inversely proportional to the magnetic pressure; however, the burst pressure of group A was smaller than those of the other groups at 1 mo(187.5 ± 17.7 vs 290 ± 10/296.7 ± 5.7/287.5 ± 3.5, P < 0.05); the remaining groups did not differ significantly. A histologic examination demonstrated obvious differences between the magnamosis groups and the hand-sewn ***: We proved that the optimal range for choledochojejunostomy magnamosis is 0.2 MPa to 0.3 MPa, which will help to improve the clinical application of this techni

采集龙口市污水灌溉区农田土壤,分析测定土壤pH和重金属含量,以采集的70个土壤样点为研究对象,根据多元统计中的相关分析和主成分分析探究研究区重金属的来源;采用地统计理论与GIS空间插值相结合的方法研究重金属元素的空间结构和分布特征;最后利用内梅罗指数法和改进的模糊综合评判法做重金属污染评价.结果表明,研究区内9种重金属元素在土壤中均有一定程度的富集,其中重金属Cd的均值是当地背景值的3.06倍,富集情况最为明显;指数法进行的污染评价显示Cu、Cd和Pb的综合污染指数分别为7.06、6.10和5.54,三者均属重度污染;相关分析和主成分分析结果显示,Cu、Zn和Pb、Cd主要受人为因素影响,污水灌溉是它们的共同污染因素,前两者为农业生产中化肥农药的过量使用与长时间的累积作用,而北部煤矿开采和煤矸石的堆积产生的污染以及电镀、机械制造等工业污染是后两者的污染来源;Co、Cr、Mn、Ni和As主要是受成土母质等自然因素的影响;据模糊综合评判的结果,研究区70个样点,有13个是中污染程度,23个属于轻污染,28个是警戒程度,6个样点处在安全范围内;从空间分布上看,重金属含量的高值区主要集中在黄水河下游的诸由观镇和徐福镇,说明污水灌溉给当地土壤造成了一定程度的重金属污染.
