| 1 | Impact of referral pattern and timing of repair on surgical outcome after reconstruction of post-cholecystectomy bile duct injury:A multicenter study显示文摘Background:Bile duct injury(BDI)after cholecystectomy remains a significant surgical challenge.No guideline exists to guide the timing of repair,while few studies compare early versus late repair BDI.This study aimed to analyze the outcomes in patients undergoing immediate,intermediate,and delayed repair of BDI.Methods:We retrospectively analyzed 412 patients with BDI from March 2015 to January 2020.The patients were divided into three groups based on the time of BDI reconstruction.Group 1 underwent an immediate reconstruction(within the first 72 hours post-cholecystectomy,n=156);group 2 underwent an intermediate reconstruction(from 4 days to 6 weeks post-cholecystectomy,n=75),and group 3 underwent delayed reconstruction(after 6 weeks post-cholecystectomy,n=181).Results:Patients in group 2 had significantly more early complications including anastomotic leakage and intra-abdominal collection and late complications including anastomotic stricture and secondary liver cirrhosis compared with groups 1 and 3.Favorable outcome was observed in 111(71.2%)patients in group 1,31(41.3%)patients in group 2,and 157(86.7%)patients in group 3(P=0.0001).Multivariate analysis identified that complete ligation of the bile duct,level E1 BDI and the use of external stent were independent factors of favorable outcome in group 1,the use of external stent was an independent factor of favorable outcome in group 2,and level E4 BDI was an independent factor of unfavorable outcome in group 3.Transected BDI and level E4 BDI were independent factors of unfavorable outcome.Conclusions:Favorable outcomes were more frequently observed in the immediate and delayed reconstruction of post-cholecystectomy BDI.Complete ligation of the bile duct,level E1 BDI and the use of external stent were independent factors of a favorable outcome. | Ayman El Nakeeb Ahmad Sultan Helmy Ezzat Mohamed Attia Mohamed Abd ElWahab Taha Kayed Ayman Hassanen Ahmad AlMalki Ahmed Alqarni Mohammed M Mohammed | 2021 | Hepatobiliary & Pancreatic Diseases International2021，20，1： | 4 |

| 9 | 单层金刚石工具螺旋钻削复合材料的性能比较显示文摘使用不同形状、不同磨粒尺寸的单层金刚石工具以螺旋钻孔方式加工多向碳纤维-环氧树脂层压板,比较各工具的加工性能。在复合材料上钻孔时,和传统钻削相比,螺旋钻孔是更先进和完善的方法。选择7种不同工具开展性能试验,研究金刚石磨粒尺寸、刀具槽口类型和末端几何形状对钻进力、温度、钻进缺陷和表面完整性的影响。结果发现高速旋转钻削可以显著降低钻削力。使用磨粒尺寸更小的工具进行加工,可以改善钻孔表面粗糙度,但是其钻削力更大、钻削温度更高。带有槽口的工具可以减轻工具表面堵塞。和平直末端或无槽口的工具相比,球形末端的工具性能更好。 | SULTANA Ireen 史忠德 ATTIA Helmi THOMSON Vincent | 2023 | 金刚石与磨料磨具工程2023，43，3： | 0 |
| 10 | Effects of dual sofosbuvir/daclatasvir therapy on, chronic hepatitis C infected, survivors of childhood malignancy显示文摘BACKGROUND Childhood cancer survivors are potentially at a higher risk of infection with hepatitis C virus (HCV).The effects of all-oral direct-acting antiviral therapy (DAA) on both the HCV infection as well as the state of cancer remission have not been well investigated in this population.AIM To test the effects of dual sofosbuvir/daclatasvir (SOF/DCV) therapy in the treatment of chronic HCV in survivors of hematologic malignancy in pediatric age group.METHODS We conducted a prospective,uncontrolled,open-label multicenter study.A total of 20 eligible,chronic HCV,genotype-4,infected children who had been in continuous complete remission from hematologic cancer (leukemia/lymphoma) for at least one year were included in the study.All patients were treated with combined SOF/DCV for 12 wk.Patients were monitored throughout the study till 12 wk after end of treatment for safety and efficacy outcomes including the sustained virologic response 12 (SVR12) rate,hematological indices,liver and kidney functions.RESULTS The intent-to-treat SVR12 rate was 20 of 20 (100%;95%CI: 84%-100%).All patients showed normalized liver enzymes from week-4.All hematological indices,liver and kidney functions were kept normal throughout the study.No fatalities or treatment-emergent serious or severe adverse events were reported throughout the study.CONCLUSION SOF/DCV combined therapy could be used safely and effectively in the treatment of chronic HCV genotype-4 infection in leukemia/lymphoma treated children.No relapses were detected during treatment and throughout the follow up period for either the original malignant disease or the HCV infection. | Mortada HF El-Shabrawi Laila M Sherief Mostafa Yakoot Naglaa M Kamal Mohamed A Almalky Manal M AbdElgawad Aml A Mahfouz Sherine Helmy Enas M Kamal Dina Attia Hisham R El-Khayat | 2019 | World Journal of Clinical Cases2019，7，16： | 0 |
| 11 | Rock composition and origin of the Duwi Formation calcareous rocks, Upper Egypt显示文摘Upper Cretaceous phosphorite beds of the Duwi Formation, Upper Egypt, are intercalated with limestone, sandy limestone, marl, calcareous shales, and calcareous sandstone. Calcareous intercalations were subjected to field and detailed petrographic, mineralogical and geochemical investigations in order to constrain their rock composition and origin.; Mineralogically, dolomite, calcite, quartz, francolite and feldspars are the non-clay minerals. Smectite, kaolinite and illite represent the clay minerals. Major and trace elements can be classified as the detrital and carbonate fractions based on their sources. The detrital fraction includes the elements that are derived from detrital sources, mainly clay minerals and quartz, such as Si, Al, Fe, Ti, K, Ba, V, Ni, Co, Cr, Zn, Cu, Zr, and Mo. The carbonate fraction includes the elements that are derived from carbonates, maily calcite and dolomite, such as Ca, Mg and Sr. ; Dolomite occurs as being dense, uniform, mosaic, very fine-to-fine, non-ferroan, and non-stoichiometrical, suggesting its early diagenetic formation in a near-shore oxidizing shallow marine environment. The close association and positive correlation between dolomite and smectite indicates the role of clay minerals in the formation of dolomite as a source of Mg{2}-rich solutions.; Calcareous rocks were deposited in marine, oxidizing and weakly alkaline conditions, marking a semi-arid climatic period. The calcareous/argillaceous alternations are due to oscillations in clay/carbonate ratio. | Baioumy H.M. Attia A.M. Boulis S.N. Hassan M.S.
