2An overview of PCI in the very elderly显示文摘心血管的疾病,和特别地 ischemic 心疾病(IHD ) ,是病态和死亡的一个主要原因在老(>80 年) 世界范围。这些病人代表为经皮的冠的干预(一种总线标准) 介绍的一个很快成长的队,现在在五个病人组成超过一在真实世界的实践与一种总线标准对待。而且,他们经常比他们的更年轻的对应物有更大的 ischemic 负担,建议他们有从冠的 revascularization 治疗的利益的更大的范围。尽管有这,老在那里在临床的 revascularization 试用并且历史上经常是未被充分代表的是在为一种总线标准过程提交他们的医生勉强的度与令人失望的结果的感觉,低成功和高复杂并发症评价。几个问题贡献了这,包括为有晚介绍的 IHD 的更老的病人的趋势,与不正常的症状或关于他们的程序的 risk-to-benefit 比率的非诊断的 ECG,和保留由于更短的预期寿命,从 antiplatelet 和 anticoagulation 药的 comorbidities 和增加的流血风险的存在。然而,在在过去的十年的一种总线标准技术和技术的进展导致了更好的结果和复杂并发症和存在身体的更低的风险证据现在显示那老实际上比更年轻的人口从一种总线标准导出更相对的利益。重要地,这适用于所有一种总线标准背景:选任,迫切并且紧急情况。这评论在与长期的稳定的 IHD 的老介绍讨论一种总线标准的角色,非圣举起急性冠的症候群,和圣举起心肌的梗塞。当认为在为研究和开发的这个队和进行中的需要的一种总线标准进一步在这些挑战性的病人改进结果时,它也探讨遇见的临床的挑战。Vimalraj Bogana Shanmugam Richard Harper Ian Meredith Yuvaraj Malaiapan Peter J Psaltis 2015Journal of Geriatric Cardiology2015,12,2:22
3Management of postoperative spinal infections显示文摘Postoperative surgical site infection(SSI) is a common complication after posterior lumbar spine surgery. This review details an approach to the prevention,diagnosis and treatment of SSIs. Factors contributing to the development of a SSI can be split into three categories:(1) microbiological factors;(2) factors related to the patient and their spinal pathology; and(3) factors relating to the surgical procedure. SSI is most commonly caused by Staphylococcus aureus. The virulence of the organism causing the SSI can affect its presentation. SSI can be prevented by careful adherence to aseptic technique,prophylactic antibiotics,avoiding myonecrosis by frequently releasing retractors and preoperatively optimizing modifiable patient factors. Increasing pain is commonly the only symptom of a SSI and can lead to a delay in diagnosis. C-reactive protein and magnetic resonance imaging can help establish the diagnosis. Treatment requires acquiring intra-operative cultures to guide future antibiotic therapy and surgical debridement of all necrotic tissue. A SSI can usually be adequately treated without removing spinalinstrumentation. A multidisciplinary approach to SSIs is important. It is useful to involve an infectious disease specialist and use minimum serial bactericidal titers to enhance the effectiveness of antibiotic therapy. A plastic surgeon should also be involved in those cases of severe infection that require repeat debridement and delayed closure.Vishal Hegde Dennis S Meredith Christopher K Kepler Russel C Huang 2012World Journal of Orthopedics2012,3,11:17

7In vivo radiometric analysis of glucose uptake and distribution in mouse bone显示文摘Bone formation and remodeling occurs throughout life and requires the sustained activity of osteoblasts and osteoclasts,particularly during periods of rapid bone growth.Despite increasing evidence linking bone cell activity to global energy homeostasis,little is known about the relative energy requirements or substrate utilization of bone cells.In these studies,we measured the uptake and distribution of glucose in the skeleton in vivo using positron-emitting^(18)F-fluorodeoxyglucose([^(18)F]-FDG) and non-invasive,high-resolution positron emission tomography/computed tomography(PET/CT) imaging and ex vivo autoradiography.Assessment of [^(18)F]-FDG uptake demonstrated that relative to other tissues bone accumulated a significant fraction of the total dose of the glucose analog.Skeletal accumulation was greatest in young mice undergoing the rapid bone formation that characterizes early development.PET/CT imaging revealed that [^(18)F]-FDG uptake was greatest in the epiphyseal and metaphyseal regions of long bones,which accords with the increased osteoblast numbers and activity at this skeletal site.Insulin administration significantly increased skeletal accumulation of [^(18)F]-FDG,while uptake was reduced in mice lacking the insulin receptor specifically in osteoblasts or fed a high-fat diet.Our results indicated that the skeleton is a site of significant glucose uptake and that its consumption by bone cells is subject to regulation by insulin and disturbances in whole-body metabolism.Meredith L Zoch Diane S Abou Thomas L Clemens Daniel LJ Thorek Ryan C Riddle 2016Bone Research2016,4,1:9
8柴达木盆地大红沟剖面新生代地层磁组构特征及构造意义显示文摘研究表明柴达木盆地新生代沉积物磁化率各向异性能够有效地记录印度-欧亚板块碰撞的应力场方向,然而过去对该盆地磁组构研究主要集中在始新世下干柴沟组和中新世下油砂山组,因此不能有效界定应力场方向发生变化的年代。本文对柴达木盆地北缘大红沟剖面沉积岩进行了详细的磁组构分析,获得了新生代较高分辨率(平均6~10m)的磁化率各向异性数据。结果表明,下干柴沟组、上干柴沟组、下油砂山组和上油砂山组及狮子沟组磁面理发育较为明显,磁化率椭球体呈压扁状,具有较强的压扁效应;而路乐河组磁线理发育更为明显,可能记录了较强的构造作用力。路乐河组和下干柴沟组磁组构指示构造应力的方向为近南北向;上干柴沟组和下油砂山组磁组构指示应力的方向为东北-西南向。因此,柴达木盆地由南北向挤压转变为东北-西南向挤压发生在始新世下干柴沟组和渐新世上干柴沟组之间,指示青藏高原北部应力场发生了变化。我们将青藏高原北部应力场的转变归因于阿尔金断裂的左旋走滑,而中晚中新世应力的进一步加强可能与下地壳流或昆仑山断裂开始走滑也有关系。这一研究加深了对青藏高原北部变形机制的理解。苏庆达 聂军胜 Joel E.

9Long interspersed nuclear element ORF-1 protein promotes proliferation and resistance to chemotherapy in hepatocellular carcinoma显示文摘AIM:To clarify the specific roles and mechanisms of long interspersed nuclear element-1 ORF-1 protein [human long interspersed nuclear element-1(LINE-1),ORF-1p] in chemotherapeutic drug resistance and cell proliferation regulation in hepatocellular carcinoma(HCC) cells.METHODS:MTT assays were performed to identify the effect of the chemotherapeutic drug toxicity on HepG2 cells.Cell proliferation inhibition and the IC 50 were calculated by the Origin 8.0 software.Western blotting assays were performed to investigate whether LINE-1 ORF-1p modulates the expression of some important genes,including p53,p27,p15,Bcl-2,mdr,and p-gp.To corroborate the proliferation and anchor-independent growth results,the HepG2 cells were analyzed by flow cytometry to investigate the effect of LINE-1 ORF1p on the apoptosis regulation.RESULTS:LINE-1 ORF-1p contributed to the resistance to several chemotherapeutic drugs(cisplatin and epirubicin) in HepG2 cells.The IC 50 of the epirubicin and cisplatin increased from 36.04 nmol/L to 59.11 nmol/L or from 37.94 nmol/L to 119.32 nmol/L.Repression of LINE-1 ORF-1p expression by the siRNA could markedly enhance the response of HepG2 cells to the epirubicin and cisplatin.The IC 50 correspondingly decreased from 28.06 nmol/L to 3.83 nmol/L or from 32.04 nmol/L to 2.89 nmol/L.Interestingly,down-regulation of LINE-1 ORF-1p level by siRNA could promote the response of HepG2 cells to the paclitaxel.The IC 50 decreased from 35.90 nmol/L to 7.36 nmol/L.However,overexpression of LINE-1 ORF-1p did not modulate the paclitaxel toxicity in HepG2 cells.Further Western blotting revealed that LINE-1 ORF-1p enhanced mdr and p-gp gene expression.As a protein arrested in the nucleus,LINE-1 ORF-1p may function through modulating transcriptional activity of some important transcription factors.Indeed,LINE-1 ORF-1p promoted HepG2 cell proliferation,anchor-independent growth and protected the cells against apoptosis through modulating the expression of p15,p21,p53,and Bcl-2 genes.CONCLUSION:LINE-1 ORF-1p promotes HepG2 cell proliferation and plays an important role in the resistance of chemotherapeutic drugs.By establishing novel roles and defining the mechanisms of LINE-1 ORF1p in HCC chemotherapeutic drug resistance and cell proliferation regulation,this study indicates that LINE-1 ORF-1p is a potential target for overcoming HCC chemotherapeutic resistance.Fan Feng Yin-Ying Lu Fan Zhang Xu-Dong Gao Chuan-Fu Zhang Alex Meredith Zhong-Xian Xu Yu-Tao Yang Xiu-Juan Chang Hong Wang Jian-Hui Qu Zhen Zeng Jun-Lan Yang Chun-Ping Wang Yun-Feng Zhu Jia-Jun Cui Yong-Ping Yang 2013World Journal of Gastroenterology2013,19,7:8
10Prolonged 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 2019World Journal of Hepatology2019,11,8:6

19Spontaneous intramural duodenal hematoma in type 2B von Willebrand disease显示文摘Intramural duodenal hematoma is a rare cause of a proximal gastrointestinal tract obstruction.Presentation of intramural duodenal hematoma most often occurs following blunt abdominal trauma in children,but spontaneous non-traumatic cases have been linked to anticoagulant therapy,pancreatitis,malignancy,vasculitis and endoscopy.We report an unusual case of spontaneous intramural duodenal hematoma presenting as an intestinal obstruction associated with acute pancreatitis in a patient with established von Willebrand disease,type 2B.The patient presented with abrupt onset of abdominal pain,nausea,and vomiting.Computed tomography imaging identified an intramural duodenal mass consistent with blood measuring 4.7 cm×8.7 cm in the second portion of the duodenum abutting on the head of the pancreas.Serum lipase was 3828 units/L.Patient was managed conservatively with bowel rest,continuous nasogastric decompression,total parenteral nutrition,recombinant factorⅧ(humateP)and transfusion.Symptoms resolved over the course of the hospitalization.This case highlights an important complication of an inherited coagulopathy.Derrick D Eichele Meredith Ross Patrick Tang Grant F Hutchins Mark Mailliard 2013World Journal of Gastroenterology2013,19,41:3
20HDAC inhibitors improve CRISPR-mediated HDR editing efficiency in iPSCs显示文摘Genome-edited human induced pluripotent stem cells(iPSCs)hold great promise for therapeutic applications.However,low editing efficiency has hampered the applications of CRISPR-Cas9 technology in creating knockout and homology-directed repair(HDR)-edited iPSC lines,particularly for silent genes.This is partially due to chromatin compaction,inevitably limiting Cas9 access to the target DNA.Among the six HDAC inhibitors we examined,vorinostat,or suberoylanilide hydroxamic acid(SAHA),led to the highest HDR efficiency at both open and closed loci,with acceptable toxicity.HDAC inhibitors equally increased non-homologous end joining(NHEJ)editing efficiencies(~50%)at both open and closed loci,due to the considerable HDAC inhibitor-mediated increase in Cas9 and sgRNA expression.However,we observed more substantial HDR efficiency improvement at closed loci relative to open chromatin(2.8 vs.1.7-fold change).These studies provide a new strategy for HDRediting of silent genes in iPSCs.Jian-Ping Zhang Zhi-Xue Yang Feng Zhang Ya-Wen Fu Xin-Yue Dai Wei Wen Beldon Zhang Hannah Choi Wanqiu Chen Meredith Brown David Baylink Lei Zhang Hongyu Qiu Charles Wang Tao Cheng Xiao-Bing Zhang 2021Science China(Life Sciences)2021,64,9:3
