Portal hypertension caused by arterio-portal fistula between the right common iliac artery and superior mesenteric vein has not been reported. Here, we report such a case in a 35-year-old male without any history of liver disease or abdominal trauma. This case was confirmed by abdominal aorta angiography and three-dimensional angiography, and was(More)
Transient outward K+ current (I to) plays a crucial role in shaping the early phase of repolarization and setting the plateau voltage level of action potential. As a result, it extensively affects membrane current flow in the plateau window. A great body of evidence illustrates a transmural gradient of I to within ventricular wall with much higher density(More)
A 70-year-old man was referred to our institution due to 2 days of vomiting and melena, 20 months after the placement of a transjugular intrahepatic portosystemic shunt (TIPS). He underwent TIPS treatment in another hospital due to repeated upper gastrointestinal variceal bleeding (GI) secondary to alcoholic cirrhosis and portal hypertension. Up until this(More)
OBJECTIVE To evaluate the agreement and correlation between hepatic vein pressure gradient (HVPG) and portal vein pressure (PVP) in patients with portal hypertension,and explore their clinical value. METHODS A total of 46 patients with portal hypertension were directly measured the free hepatic pressure, wedged hepatic pressure, portal vein pressure(More)
OBJECTIVE To investigate the quantity and distribution of motor fiber of rat's C7 nerve root. METHODS Motor fiber quantity and section area in the main nerves of the upper extremity and the fascicles of C7 in 30 SD rats were analyzed. RESULTS Fascicles and certain amount (207) of motor fibers from the anterior division of C7 were distributed to(More)
Prostate cancer is relatively common cancer occurring in males. Radical prostatectomy (RP) is the most effective treatment for a localized tumor but erectile dysfunction (ED) is common complication, even when bilateral nerve-sparing RP (BNSRP) is performed. Clinical trials have shown varied effectiveness of phosphodiesterase type-5 inhibitors (PDE5-Is) for(More)
Observation of circulation in replanted severed fingers often relies on the clinical experience of the doctor. This article discusses nail fold capillary loops (NFCL) observation in the monitoring of the perfusion and circumfluence of replanted digits. In our study, 30 patients with a total of 39 replanted digits were selected. The WX-9A900 Microcirculation(More)
The nonlinear transmission and phase noise tolerance performance of three different 8-ary constellations (8PSK, star-shaped 8QAM and circular 8QAM) in coherent optical communication systems are investigated with the improved Viterbi-Viterbi algorithms for carrier phase estimation and radius-directed linear Kalman filter for polarization de-multiplexing.
AIMS This study was aimed to provide safety guidance of needle passes into the portal vein during transjugular intrahepatic portosystemic shunt (TIPS) placement. METHODOLOGY On anteroposterior venograms, the orifice of right hepatic trunk (RHT), furcation position, and branching of portal trunk in 128 patients underwent TIPS were mapped in relation to the(More)
Graves' disease is an autoimmune disease of the thyroid gland, which is characterized by hyperthyroidism, diffuse goiter and Graves' ophthalmopathy (GO). Although several therapeutic strategies for the treatment of GO have been developed, the effectiveness and the safety profile of these therapies remain to be fully elucidated. Therefore, examination of(More)
