During the boreal summer,intraseasonal oscillations exhibit significant interannual variations in intensity over two key regions:the central-western equatorial Pacific(5°S-5°N,150°E-150°W)and the subtropical Northwestern Pacific(10°-20°N,130°E-175°W).The former is well-documented and considered to be influenced by the ENSO,while the latter has received comparatively less attention and is likely influenced by the Pacific Meridional Mode(PMM),as suggested by partial correlation analysis *** elucidate the physical processes responsible for the enhanced(weakened)intraseasonal convection over the subtropical northwestern Pacific during warm(cold)PMM years,the authors employed a moisture budget *** findings reveal that during warm PMM years,there is an increase in summer-mean moisture over the subtropical northwestern *** increase interacts with intensified vertical motion perturbations in the region,leading to greater vertical moisture advection in the lower troposphere and consequently resulting in convective *** a process is pivotal in amplifying intraseasonal convection *** observational findings were further verified by model experiments forced by PMM-like sea surface temperature patterns.

Experiments are carried out to study the characteristics of active bubbles entrained by breaking waves as these propagate over an abruptly topographical change or a submerged breakwater. Underwater sounds generated by the entrained air bubbles are detected by a hydrophone connected to a charge amplifier and a data acquisition system. The size distribution of the bubbles is then determined inversely from the received sound frequencies. The sound signals are converted from time domain to time-frequency domain by applying Gabor transform. The number of bubbles with different sizes are counted from the signal peaks in the time-frequency domain. The characteristics of the bubbles are in terms of bubble size spectra, which account for the variation in bubble probability density related to the bubble radius r. The experimental data demonstrate that the bubble probability density function shows a - 2.39 power-law sealing with radius for r 〉 0. 8 mm, and a- 1.11 power law for r 〈0.8 mm.

Rupture of hepatocellular carcinoma (HCC) is a life-threatening complication. Peritoneal metastasis of HCC after spontaneous rupture was seldom noted. We report a case of intraperitoneal metastasis of HCC after spon-taneous rupture. A previously asymptomatic 72-year-old man was admitted due to dull abdominal pain with abdominal fullness. He had a history of HCC rupture 10 mo ago and transarterial embolization was performed at that time. Abdominal computer tomograghy (CT) scan showed a huge peritoneal mass over the right up-per quadrant area. Surgical resection was arranged and subsequent microscopic examination conf irmed a diag-nosis of moderately-differentiated HCC.

Chronic pancreatitis is an ongoing disease characterized by persistent inflammation of pancreatic tissues. With disease progression, patients with chronic pancreatitis may develop troublesome complications in addition to exocrine and endocrine pancreatic functional loss. Among them, a pseudoaneurysm, mainly induced by digestive enzyme erosion of vessels in proximity to the pancreas, is a rare and life-threatening complication if bleeding of the pseudoaneurysm occurs. At present, no prospective randomized trials have investigated the therapeutic strategy for this rare but critical situation. The role of arterial embolization, the timing of surgical intervention and even surgical procedures are still controversial. In this review, we suggest that dynamic abdominal computed tomography and angiography should be performed first to localize the bleeders and to evaluate the associated complications such as pseudocyst formation, followed by arterial embolization to stop the bleeding and to achieve early stabilization of the patient’s condition. With advances and improvements in endoscopic devices and techniques, therapeutic endoscopy for pancreatic pseudocysts is technically feasible, safe and effective. Surgical intervention is recommended for a bleeding pseudoaneurysm in patients with chronic pancreatitis who are in an unstable condition, for those in whom arterial embolization of the bleeding pseudoaneurysm fails, and when endoscopic management of the pseudocyst is unsuccessful. If a bleeding pseudoaneurysm is located over the tail of the pancreas, resection is a preferential procedure, whereas if the lesion is situated over the head or body of the pancreas, relatively conservative surgical procedures are recommended.

Sorafenib is the current standard treatment for advanced hepatocellular carcinoma(HCC),but its efficacy is modest with low response rates and short response duration. Predictive biomarkers for sorafenib efficacy are necessary. However,efforts to determine biomarkers for sorafenib have led only to potential candidates rather than clinically useful predictors. Studies based on patient cohorts identified the potential of blood levels of angiopoietin-2,hepatocyte growth factor,insulin-like growth factor-1,and transforming growth factor-β1 for predicting sorafenib efficacy. Alpha-fetoprotein response,dynamic contrast-enhanced magnetic resonance imaging,and treatment-related side effects may serve as early surrogate markers. Novel approaches based on super-responders or experimental mouse models may provide new directions in biomarker research. These studies identified tumor amplification of FGF3/FGF4 or VEGFA and tumor expression of phospho-Mapk14 and phospho-Atf2 as possible predictive markers that await validation. A group effort that considers various prognostic factors and proper collection of tumor tissues before treatment is imperative for the success of future biomarker research in advanced HCC.
