| 1 | Management 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 | 2012 | World Journal of Orthopedics2012，3，11： | 17 |
| 2 | Migration of bone marrow progenitor cells in the adult brain of rats and rabbits显示文摘Neurogenesis takes place in the adult mammalian brain in three areas:Subgranular zone of the dentate gyrus(DG);subventricular zone of the lateral ventricle;olfactory bulb.Different molecular markers can be used to characterizethe cells involved in adult neurogenesis.It has been recently suggested that a population of bone marrow(BM)progenitor cells may migrate to the brain and differentiate into neuronal lineage.To explore this hypothesis,we injected recombinant SV40-derived vectors into the BM and followed the potential migration of the transduced cells.Long-term BM-directed gene transfer using recombinant SV40-derived vectors leads to expression of the genes delivered to the BM firstly in circulating cells,then after several months in mature neurons and microglial cells,and thus without central nervous system(CNS)lesion.Most of transgene-expressing cells expressed NeuN,a marker of mature neurons.Thus,BM-derived cells may function as progenitors of CNS cells in adult animals.The mechanism by which the cells from the BM come to be neurons remains to be determined.Although the observed gradual increase in transgene-expressing neurons over 16mo suggests that the pathway involved differentiation of BM-resident cells into neurons,cell fusion as the principal route cannot be totally ruled out.Additional studies using similar viral vectors showed that BM-derived progenitor cells migrating in the CNS express markers of neuronal precursors or immature neurons.Transgene-positive cells were found in the subgranular zone of the DG of the hippocampus 16 mo after intramarrow injection of the vector.In addition to cells expressing markers of mature neurons,transgene-positive cells were also positive for nestin and doublecortin,molecules expressed by developing neuronal cells.These cells were actively proliferating,as shown by short term BrdU incorporation studies.Inducing seizures by using kainic acid increased the number of BM progenitor cells transduced by SV40vectors migrating to the hippocampus,and these cells were seen at earlier time points in the DG.We show that the cell membrane chemokine receptor,CCR5,and its ligands,enhance CNS inflammation and seizure activity in a model of neuronal excitotoxicity.SV40-based gene delivery of RNAi targeting CCR5 to the BM results in downregulating CCR5 in circulating cells,suggesting that CCR5 plays an important role in regulating traffic of BM-derived cells into the CNS,both in the basal state and in response to injury.Furthermore,reduction in CCR5 expression incirculating cells provides profound neuroprotection from excitotoxic neuronal injury,reduces neuroinflammation,and increases neuronal regeneration following this type of insult.These results suggest that BM-derived,transgeneexpressing,cells can migrate to the brain and that they become neurons,at least in part,by differentiating into neuron precursors and subsequently developing into mature neurons. | Donnahue Dennie Jean-Pierre Louboutin David S Strayer | 2016 | World Journal of Stem Cells2016，8，4： | 9 |
| 3 | Mycophenolate mofetil for drug-induced vanishing bile duct syndrome显示文摘Amoxicillin/clavulanate is associated with liver injury, mostly of a cholestatic pattern. While outcomes are usually benign, progression to cirrhosis and death has been reported. The role of immunosuppressive therapy for patients with a protracted course is unclear. We report the case of an elderly patient who developed prolonged cholestasis secondary to amoxicillin/clavulanate. Vanishing bile duct syndrome was confirmed by sequential liver biopsies. The patient responded to prednisone treatment, but could not be weaned off corticosteroids, even when azathioprine was added. Complete withdrawal of both prednisone and azathioprine was possible by using mycophenolate mofetil, an inosine monophosphate dehydrogenase inhibitor. Sustained remission has been maintained for more than 3 years with low-dose mycophenolate mofetil. | S Simona Jakab A Brian West Dennis M Meighan Robert S Brown Jr William B Hale | 2007 | World Journal of Gastroenterology2007，13，45： | 8 |

| 5 | Epistaxis in end stage liver disease masquerading as severe upper gastrointestinal hemorrhage显示文摘AIM:To describe the prevalence,diagnosis,treatment,and outcomes of end stage liver disease(ESLD) patients with severe epistaxis thought to be severe upper gastrointestinal hemorrhage(UGIH).METHODS:This observational single center study included all consecutive patients with ESLD and epistaxis identified from consecutive subjects hospitalized with suspected UGIH and prospectively enrolled in our databases of severe UGIH between 1998 and 2011.RESULTS:A total of 1249 patients were registered for severe UGIH in the data basis,461(36.9%) were cirrhotics. Epistaxis rather than UGIH was the bleeding source in 20 patients. All patients had severe coagulopathy. Epistaxis was initially controlled in all cases. Fifteen(75%) subjects required posterior nasal packing and 2(10%) embolization in addition to correction of coagulopathy. Five(25%) patients died in the hospital,12(60%) received orthotopic liver transplantation(OLT),and 3(15%) were discharged without OLT. The mortality rate was 63% in patients without OLT.CONCLUSION:Severe epistaxis in patients with ESLD is(1) a diagnosis of exclusion that requires upper endoscopy to exclude severe UGIH;and(2) associated with a high mortality rate in patients not receiving OLT. | Marine Camus Dennis M Jensen Jason D Matthews Gordon V Ohning Thomas O Kovacs Rome Jutabha Kevin A Ghassemi Gustavo A Machicado Gareth S Dulai | 2014 | World Journal of Gastroenterology2014，20，38： | 3 |

| 10 | Pembrolizumab-emerging treatment of pulmonary sarcomatoid carcinoma: A case report显示文摘BACKGROUND Few studies have addressed the efficacy of pembrolizumab in pulmonary sarcomatoid carcinoma(PSC),a rare,previously rapidly fatal subtype of nonsmall-cell lung cancer.CASE SUMMARY We report the case of a 69-year-old man presented with respiratory distress caused by a large left upper lung lobe mass diagnosed as PSC with programmed death-ligand 1 expressed on more than 50 percent of tumor cells.The patient was started on pembrolizumab and,after 5 cycles,there was a more than 80 percent decrease in the size of the tumor mass.Further decrease was seen at the end of 10 cycles.The patient has been tolerating pembrolizumab well,with no limiting side-effects.Fourteen months after first coming into the hospital,he remains asymptomatic.CONCLUSION Pembrolizumab appears as a viable emerging treatment for PSC. | Emanuela Cimpeanu Jibran Ahmed Wahib Zafar Adreana DeMarinis Svetoslav S Bardarov Shamim Salman Dennis Bloomfield | 2020 | World Journal of Clinical Cases2020，8，1： | 2 |
