AIM： To evaluate the efficacy and complications of stereotactic body radiotherapy in localized paraaortic lymph node recurrence from colorectal cancer. METHODS： From 2003 to 2009, 7 patients with paraaortic lymph node recurrence （1-3 lesions） from colorectal cancer were treated with stereotactic body radiotherapy. Total gross tumor volumes ranged from 4 to 40 mL. The doses were escalated from 36 Gy/patient to 51 Gy/patient and were delivered in 3 fractions. RESULTS： One and 3 year overall survival rates were 100% and 71.4%, respectively, and median survival was 37 mo. Grade IV intestinal obstruction was reported in 1 of 7 patients. This patient received 48 Gy in 3 fractions with a maximum point dose to the intestine of 53 Gy and V45Gy = 3.6 mL. However, 6 patients received an intestinal maximum point dose of 〈 51 Gy and V45Gy of 〈 1 mL, and did not develop any severe complications. CONCLUSION： This pilot study suggests selected paraaortic lymph node recurrence （1-3 closed lesions） that failed to respond to chemotherapy can be potentially salvaged by stereotactic body radiotherapy.

BACKGROUND:Adequate airway management plays an important role in high-quality cardiopulmonary resuscitation(CPR).Airway management is usually performed using an endotracheal tube(ETT)during ***,no study has assessed the effect of ETT size on the fl ow rate and airway pressure during ***:We measured changes in peak inspiratory fl ow rate(PIFR),peak airway pressure(Ppeak),and mean airway pressure(Pmean)according to changes in ETT size(internal diameter 6.0,7.0,and 8.0 mm)and with or without CPR.A tidal volume of 500 mL was supplied at a rate of 10 times per minute using a mechanical *** compressions were maintained at a constant compression depth and speed using a mechanical chest compression device(LUCAS2,mode:active continuous,chest compression rate:102±2/minute,chest compression depth 2–2.5 inches).RESULTS:The median of several respiratory physiological parameters during CPR was significantly different according to the diameter of each ETT(6.0 vs.8.0 mm):PIFR(32.1 L/min[30.5–35.3]vs.28.9 L/min[27.5–30.8],P<0.001),Ppeak(48.84 cmH2O[27.46–52.11]vs.27.45 cmH2O[22.53–52.57],P<0.001),and Pmean(18.34 cmH2O[14.61–21.66]vs.13.66 cmH2O[8.41–19.24],P<0.001).CONCLUSION:The changes in PIFR,Ppeak,and Pmean were related to the internal diameter of ETT,and these values tended to decrease with an increase in ETT *** airway pressures were measured in the CPR group than in the no CPR group.

Ischemic injury to the bowel is a well known disease entity that has a wide spectrum of pathological and clinical findings. A sudden drop in the colonic blood supply is essential to its development. We encountered a 41-year-old male patient, who presented with abdominal pain and bloody diarrhea. A colonoscopy showed markedly edematous mucosa with tortuous dilatation of the veins and a deep ulceration at the rectosigmoid junction. On an abdominal computed tomography (CT) scan and CT angiography, the mesenteric and splenic veins were absent with numerous venous collaterals for drainage. The patient gradually responded to oral aminosalicylate therapy, and was in remission after nine months. In most cases, non-occlusive ischemic injury is caused by idiopathic form and occlusive ischemia is caused by abnormalities of arteries and acute venous thrombosis. However, chronic venous insufficiency due to obstruction of macrovascular mesenteric vein rarely causes ischemia of the bowel. This report describes the first case of ischemic colitis caused by obstruction of the mesenteric and splenic veins.

AIM：To report the effect of focal laser photocoagulation on both the severity of hard exudates（HEs） and the rate of disease progression in eyes with mild to moderate non-proliferative diabetic retinopathy（NPDR）.METHODS： We retrospectively reviewed the medical records of 33 patients（60 eyes） who had been diagnosed with mild to moderate NPDR between January 2006 and December *** patients were divided into 2 groups：Group A（38 eyes in 20 patients treated using focal laser photocoagulation） and Group B（treated without laser photocoagulation）.We also reviewed the best corrected visual acuity measurements,and the fundus photographs taken at both baseline and follow-up visits. RESULTS： In Group A,HE severity grade had decreased significantly from baseline to the final visit（P 〈0.05）,but this was not the case in Group B（P =0.662）.The cumulative probabilities of retinopathy progression at 5y were 26% in Group A and 30% in Group *** survival curves showed no significant difference between the groups with regard to retinopathy progression（P =0.805）.CONCLUSION： Focal laser photocoagulation reduced the levels of HEs in eyes with mild to moderate ***,the treatment was not able to decelerate the progression of DR.

We report the phenomenon of size segregation and the experimental evidence for the presence of correlated areas mediated by dipolar interactions in three-dimensional Fe nanoparticle *** nanoparticles dispersed in ethanol assemble into tabular whiskers (8 μm × 40 μm in cross section with lengths up to 1 0 cm) due to dipolar *** force microscopy observations on iron nanoparticle compact assemblies prove the local magnetic correlation of the Fe nanoparticles due to dipolar coupling and the formation of domain-like structures in expanded *** measurements show that the coercivity and the low field magnetic susceptibility of the Fe nanoparticle assemblies increase while the saturation magnetization decreases with the increasing interparticle distance.

BACKGROUND Recently,the exclusive use of mesenchymal stem cell(MSC)-secreted molecules,called secretome,rather than cells,has been evaluated for overcoming the limitations of cell-based therapy,while maintaining its ***,the use of na?ve secretome may not fully satisfy the specificity of each ***,it appears to be more advantageous to use the functionally reinforced secretome through a series of processes involving physico-chemical adjustments or genetic manipulation rather than to the use na?ve *** To determine the therapeutic potential of the secretome released from miR-122-transfected adipose-derived stromal cells(ASCs).METHODS We collected secretory materials released from ASCs that had been transfected with antifibrotic miR-122(MCM)and compared their antifibrotic effects with those of the na?ve secretome(CM).MCM and CM were intravenously administered to the mouse model of thioacetamide-induced liver fibrosis,and their therapeutic potentials were *** MCM infusion provided higher therapeutic potential in terms of:(A)Reducing collagen content in the liver;(B)Inhibiting proinflammatory cytokines;and(C)Reducing abnormally elevated liver enzymes than the infusion of the na?ve *** proteomic analysis of MCM also indicated that the contents of antifibrotic proteins were significantly elevated compared to those in the na?ve *** We could,thus,conclude that the secretome released from miR-122-transfected ASCs has higher antifibrotic and anti-inflammatory properties than the na?ve *** miR-122 transfection into ASCs provides a specific way of potentiating the antifibrotic properties of ASC secretome,it could be considered as an enhanced method for reinforcing secretome effectiveness.
