| 2 | Prolonged high-fat-diet feeding promotes non-alcoholic fatty liver disease and alters gut microbiota in mice显示文摘BACKGROUND Non-alcoholic fatty liver disease (NAFLD) has become an epidemic largely due to the worldwide increase in obesity. While lifestyle modifications and pharmacotherapies have been used to alleviate NAFLD, successful treatment options are limited. One of the main barriers to finding safe and effective drugs for long-term use in NAFLD is the fast initiation and progression of disease in the available preclinical models. Therefore, we are in need of preclinical models that (1) mimic the human manifestation of NAFLD and (2) have a longer progression time to allow for the design of superior treatments. AIM To characterize a model of prolonged high-fat diet (HFD) feeding for investigation of the long-term progression of NAFLD. METHODS In this study, we utilized prolonged HFD feeding to examine NAFLD features in C57BL/6 male mice. We fed mice with a HFD (60% fat, 20% protein, and 20% carbohydrate) for 80 wk to promote obesity (Old-HFD group, n = 18). A low-fat diet (LFD)(14% fat, 32% protein, and 54% carbohydrate) was administered for the same duration to age-matched mice (Old-LFD group, n = 15). An additional group of mice was maintained on the LFD (Young-LFD, n = 20) for a shorter duration (6 wk) to distinguish between age-dependent and age-independent effects. Liver, colon, adipose tissue, and feces were collected for histological and molecular assessments.RESULTS Prolonged HFD feeding led to obesity and insulin resistance. Histological analysis in the liver of HFD mice demonstrated steatosis, cell injury, portal and lobular inflammation and fibrosis. In addition, molecular analysis for markers of endoplasmic reticulum stress established that the liver tissue of HFD mice have increased phosphorylated Jnk and CHOP. Lastly, we evaluated the gut microbial composition of Old-LFD and Old-HFD. We observed that prolonged HFD feeding in mice increased the relative abundance of the Firmicutes phylum. At the genus level, we observed a significant increase in the abundance of Adercreutzia, Coprococcus, Dorea, and Ruminococcus and decreased relative abundance of Turicibacter and Anaeroplasma in HFD mice. CONCLUSION Overall, these data suggest that chronic HFD consumption in mice can mimic pathophysiological and some microbial events observed in NAFLD patients. | Kandy T Velázquez Reilly T Enos Jackie E Bader Alexander T Sougiannis Meredith S Carson Ioulia Chatzistamou James A Carson Prakash S Nagarkatti Mitzi Nagarkatti E Angela Murphy | 2019 | World Journal of Hepatology2019，11，8： | 6 |
| 3 | Port site infection in laparoscopic surgery: A review of its management显示文摘Laparoscopic surgery(LS), also termed minimal access surgery, has brought a paradigm shift in the approach to modern surgical care. Early postoperative recovery, less pain, improved aesthesis and early return to work have led to its popularity both amongst surgeons and patients. Its application has progressed from cholecystectomies and appendectomies to various other fields including gastrointestinal surgery, urology, gynecology and oncosurgery. However, LS has its own package of complications. Port site infection(PSI), although infrequent, is one of the bothersome complications which undermine the benefits of minimal invasive surgery. Not only does it add to the morbidity of the patient but also spoils the reputation of the surgeon. Despite the advances in the field of antimicrobial agents, sterilization techniques, surgical techniques, operating room ventilation, PSIs still prevail. The emergence of rapid growing atypical mycobacteria with multidrug resistance, which are the causative organism in most of the cases, has further compounded the problem. PSIs are preventable if appropriate measures are taken preoperatively, intraoperatively and postoperatively. PSIs can often be treated non-surgically, with early identification and appropriate management. Macrolides, quinolones and aminoglycosides antibiotics do show promising activity against the atypical mycobacteria. This review article highlights the clinical burden, presentations and management of PSIs in LS as shared by various authors in the literature. We have given emphasis to atypical mycobacteria, which are emerging as a common etiological agent for PSIs in LS. Although the existing literature lacks consensus regarding PSI management, the complication can be best avoided by strictly abiding by the commandments of sterilization techniques of the laparoscopic instruments with appropriate sterilizing agent. | Prakash K Sasmal Tushar S Mishra Satyajit Rath Susanta Meher Dipti Mohapatra | 2015 | World Journal of Clinical Cases2015，3，10： | 6 |
| 4 | 氧化铝对铁矿石烧结质量和生产率的影响(英文)显示文摘烧结矿是现代高炉生产的主要含铁原料。合理控制入炉烧结矿的理化性能与冶金性能对高炉生产和稳定操作是很必要的。铁矿粉是烧结矿的主要原料,其化学成分和烧结料层内的热量条件在烧结过程中起着重要的作用。化学成分等参数也决定着烧结矿矿相结构和质量。由于含氧化铝原料的低反应性及其液相的高粘性,因此在人们的预料中高铝矿石对烧结矿结构组成的影响并不好。烧结混合料中的氧化铝在同化过程中需要消耗大量热量,延迟烧结过程。在确保高炉渣的流动性方面,氧化铝也需要消耗较大热量。不论是烧结还是高炉的生产实绩均表明,氧化铝是有害的。一般而言,高含铁量与低脉石的印度矿与其他矿石的不同特点就是氧化铝含量高。由于高品味铁矿石的消耗殆尽,使用可利用的烧结原料成为生产必需。因此,必须要掌握氧化铝的作用及其对烧结矿质量和生产过程的影响。实验室完成了不同氧化铝含量水平(2.00%~5.46%)的实验,可从中了解氧化铝在烧结矿矿物学、生产率、物理性能和冶金性能方面的影响。随着烧结矿中氧化铝含量的增加,残存赤铁矿、复合铁酸钙(SFCA)和孔隙率增加,而磁铁矿和硅酸盐比例下降。烧结生产率和烧结矿转鼓强度(TI)随着氧化铝含量上升而下降,反映烧结矿冶金性能的诸如低温还原粉化率(RDI)和还原率(RI)提高。 | T Umadevi S Prakash U K Bandopadhyay P C Mahapatra M Prabhu Madhu Ranjan | 2010 | 世界钢铁2010，，1： | 4 |

| 8 | Anticoagulation in simultaneous pancreas kidney transplantation - On what basis?显示文摘BACKGROUND Despite technical refinements,early pancreas graft loss due to thrombosis continues to occur.Conventional coagulation tests(CCT)do not detect hypercoagulability and hence the hypercoagulable state due to diabetes is left untreated.Thromboelastogram(TEG)is an in-vitro diagnostic test which is used in liver transplantation,and in various intensive care settings to guide anticoagulation.TEG is better than CCT because it is dynamic and provides a global hemostatic profile including fibrinolysis.AIM To compare the outcomes between TEG and CCT(prothrombin time,activated partial thromboplastin time and international normalized ratio)directed anticoagulation in simultaneous pancreas and kidney(SPK)transplant recipients.METHODS A single center retrospective analysis comparing the outcomes between TEG and CCT-directed anticoagulation in SPK recipients,who were matched for donor age and graft type(donors after brainstem death and donors after circulatory death).Anticoagulation consisted of intravenous(IV)heparin titrated up to a maximum of 500 IU/h based on CCT in conjunction with various clinical parameters or directed by TEG results.Graft loss due to thrombosis,anticoagulation related bleeding,radiological incidence of partial thrombi in the pancreas graft,thrombus resolution rate after anticoagulation dose escalation,length of the hospital stays and,1-year pancreas and kidney graft survival between the two groups were compared.RESULTS Seventeen patients who received TEG-directed anticoagulation were compared against 51 contemporaneous SPK recipients(ratio of 1:3)who were anticoagulated based on CCT.No graft losses occurred in the TEG group,whereas 11 grafts(7 pancreases and 4 kidneys)were lost due to thrombosis in the CCT group(P=0.06,Fisher’s exact test).The overall incidence of anticoagulation related bleeding(hematoma/gastrointestinal bleeding/hematuria/nose bleeding/re-exploration for bleeding/post-operative blood transfusion)was 17.65%in the TEG group and 45.10%in the CCT group(P=0.05,Fisher’s exact test).The incidence of radiologically confirmed partial thrombus in pancreas allograft was 41.18%in the TEG and 25.50%in the CCT group(P=0.23,Fisher’s exact test).All recipients with partial thrombi detected in computed tomography(CT)scan had an anticoagulation dose escalation.The thrombus resolution rates in subsequent scan were 85.71%and 63.64%in the TEG group vs the CCT group(P=0.59,Fisher’s exact test).The TEG group had reduced blood product usage{10 packed red blood cell(PRBC)and 2 fresh frozen plasma(FFP)}compared to the CCT group(71 PRBC/10 FFP/2 cryoprecipitate and 2 platelets).The proportion of patients requiring transfusion in the TEG group was 17.65%vs 39.25%in the CCT group(P=0.14,Fisher’s exact test).The median length of hospital stay was 18 days in the TEG group vs 31 days in the CCT group(P=0.03,Mann Whitney test).The 1-year pancreas graft survival was 100%in the TEG group vs 82.35%in the CCT group(P=0.07,log rank test)and,the 1-year kidney graft survival was 100%in the TEG group vs 92.15%in the CCT group(P=0.23,log tank test).CONCLUSION TEG is a promising tool in guiding judicious use of anticoagulation with concomitant prevention of graft loss due to thrombosis,and reduces the length of hospital stay. | Jeevan Prakash Gopal Frank JMF Dor Jeremy S Crane Paul E Herbert Vassilios E Papalois Anand SR Muthusamy | 2020 | World Journal of Transplantation2020，10，7： | 2 |
