AIM: To analyze the features of the filtering blebs following implantation of the Ex-PRESS glaucoma device(model P-50) with the aid of the Visante anterior segment optical coherence tomography(AS-OCT)METHODS: Five patients with open angle glaucomas were included in the study. They all underwent implantation of the Ex-PRESS device under a scleral flap. The surgical procedure was augmented with the use of mitomycin C subconjunctivally. The filtering blebs were analyzed with the Visante AS-OCT with the scans taken along the axis of the implantation of the glaucoma ***: All filtering blebs were graded as diffuse functioning. The morphological characteristics of the blebs were similar to those of the *** the use of the Ex-PRESS implant tend to form a characteristic episcleral lake at the site of the plate of the implant. CONCLUSION: The use of the Ex-PRESS implant produces filtering blebs similar to those of the trabeculectomy with the formation of a characteristic episcleral lake at the site of the plate of the implant.

We perform first-principles calculations and coherent laser-matter interaction analyses to investigate the laser-induced ultrafast spin flip on graphene nanoflakes(GNFs)with transition metal elements attached on the boundary[TM&GNFs(TM=Fe,Co,Ni)].It is shown that the spin-flip process on TM&GNFs is highly influenced by the involved element species and the position attached to the ***,taking Ni&GNF as an example,the first-principles tensile test predicts that the variation of the C-Ni bond length plays an important role in the spin density distribution,especially for the low-lying magnetic states,and can therefore dominate the spin-flip *** fastest spin-flip scenario is achieved within 80 fs in a Ni&GNF structure under 10%tensile strain along the C-Ni *** local deformation modulation of spin flip provides the precursory guidance for further study of ultrafast magnetization control in GNFs,which could lead to potential applications in future integrated straintronic devices.

A new pancreaticojejunostomy technique: A battle against postoperative pancreatic fistula

World Journal of Gastroenterology 2013年第27期19卷 4351-4355页

AIM:To present a new technique of end-to-side, ductto-mucosa pancreaticojejunostomy with seromuscular jejunal flap formation, and insertion of a silicone stent. METHODS:We present an end-to-side, duct-to-mucosa pancreaticojejunostomy with seromuscular jejunal flap formation, and the insertion of a silicone stent. This technique was performed in thirty-two consecutive patients who underwent a pancreaticoduodenectomy procedure by the same surgical team, from January 2005 to March 2011. The surgical procedure performed in all cases was classic pancreaticoduodenectomy, without preservation of the pylorus. The diagnosis of pancreatic leakage was defined as a drain output of any measurable volume of fluid on or after postoperative day 3 with an amylase concentration greater than three times the serum amylase activity. RESULTS:There were 32 patients who underwent end-to-side, duct-to-mucosa pancreaticojejunostomy with seromuscular jejunal flap formation. Thirteen of them were women and 19 were men. These data correspond to 40.6% and 59.4%, respectively. The mean age was 64.2 years, ranging from 55 to 82 years. The mean operative time was 310.2 ± 40.0 min, and was defined as the time period from the intubation up to the extubation of the patient. Also, the mean time needed to perform the pancreaticojejunostomy was 22.7 min, ranging from 18 to 25 min. Postoperatively, one patient developed a low output pancreatic fistula, three patients developed surgical site infection, and one patient developed pneumonia. The rate of overall morbidity was 15.6%. There was no 30-d postoperative mortality. CONCLUSION:This modification appears to be a significantly safe approach to the pancreaticojejunostomy without adversely affecting operative time.

von Willebrand factor antigen as a therapeutic target of portal hypertension in cirrhosis

Increased thrombotic potential within the liver sinusoids due to local endothelial production of von Willebrand factor antigen macromolecules could represent an additional therapeutic target of portal hypertension in patients with cirrhosis. In this case, anti-inflammatory and antithrombotic drugs could modulate portal pressure by preventing the formation of intrahepatic platelet-induced microthrombi.
