1Cirrhotic ascites review: Pathophysiology, diagnosis and management显示文摘Ascites is a pathologic accumulation of peritoneal fluidcommonly observed in decompensated cirrhotic states. Its causes are multi-factorial, but principally involve significant volume and hormonal dysregulation in the setting of portal hypertension. The diagnosis of ascites is considered in cirrhotic patients given a constellation of clinical and laboratory findings, and ultimately confirmed, with insight into etiology, by imaging and paracentesis procedures. Treatment for ascites is multimodal including dietary sodium restriction, pharmacologic therapies, diagnostic and therapeutic paracentesis, and in certain cases transjugular intra-hepatic portosystemic shunt. Ascites is associated with numerous complications including spontaneous bacterial peritonitis, hepato-hydrothorax and hepatorenal syndrome. Given the complex nature of ascites and associatedcomplications, it is not surprising that it heralds increased morbidity and mortality in cirrhotic patients and increased cost-utilization upon the health-care system. This review will detail the pathophysiology of cirrhotic ascites, common complications derived from it, and pertinent treatment modalities.Christopher M Moore David H Van Thiel 2013World Journal of Hepatology2013,5,5:13

3Temperature variations inside Chinese solar greenhouses with external climatic conditions and enclosure materials显示文摘Chinese solar greenhouses enable the extension of the crop growing season in the cold climate in Northern China with little or no additional heating.The temporal variations of the air temperatures inside solar greenhouses located at three cities in North,Northeast and Northwest China were predicted by CFD simulations of the greenhouse systems using typical meteorological data.The predicted temperatures based on the meteorological data in Shenyang are quite similar to the measured temperatures.The results also show that the external air temperatures and solar radiation fluxes play more important roles for the inside temperatures as indicated by the highest inner temperature in the morning on Feb.18 and from 10:00 to 14:00 on Feb.19 in Beijing and by the predicted temperatures inside the greenhouse being higher in Lanzhou than those in Shenyang and Beijing during most of the day.The average daily temperature inside the greenhouse in Lanzhou was nearly 3.5℃higher than that in Shenyang.Predicted air temperatures for various wall designs show that for single walls,the daily average interior temperatures in the aerated concrete wall greenhouse were higher than those in the brick wall and reinforced concrete wall greenhouses.However,the air temperature fluctuations were lower in the reinforced concrete wall greenhouse due to greater thermal storage capacity.The results also show that the temperatures in the layered wall greenhouses are quite similar,which coincides with the experimental results。Tong Guohong David M Christopher Li Tianlai Wang Tieliang 2008International Journal of Agricultural and Biological Engineering2008,1,2:10
4Procalcitonin,and cytokines document a dynamic inflammatory state in non-infected cirrhotic patients with ascites显示文摘AIM:To quantitate the simultaneous serum and ascitic fluid levels of procalcitonin and inflammatory markers in cirrhotics with and without ascites.METHODS:A total of 88 consecutive severe cirrhotic patients seen in a large city hospital liver clinic were studied and divided into two groups,those with and without ascites.Group 1 consisted of 41 cirrhotic patients with massive ascites,as demonstrated by necessity for therapeutic large-volume paracentesis.Group 2consisted of 47 cirrhotic patients without any clinically documented ascites to include either a recent abdominal computed tomography scan or ultrasound study.Serum and ascitic fluid levels of an array of inflammatory markers,including procalcitonin,were measured and compared to each other and a normal plasma panel(NPP).RESULTS:The values for inflammatory markers assayed in the serum of Groups 1 and 2,and ascitic fluid of the Group 1.The plasma levels of the inflammatory cytokines interleukin(IL)-2,IL-4,IL-6,IL-8,interferon gamma(IFNγ)and epidermal growth factor(EGF)were all significantly greater in the serum of Group 1as compared to that of the serum obtained from the Group 2 subjects(all P<0.05).There were significantly greater serum levels of IL-6,IL-8,IL-10,monocyte chemoattractant protein-1,tumor necrosis factor-α,vascular endothelial growth factor and EGF when comparing Group 2 to the NPP.There was no significant difference for IL-1A,IL-1B,IL-2,IL-4 and IFNγlevels between these two groups.Serum procalcitonin levels were increased in cirrhotics with ascites compared to cirrhotics without ascites,but serum levels were similar to ascites levels within the ascites group.Furthermore,many of these cytokines,but not procalcitonin,demonstrate an ascites-to-serum gradient.Serum procalcitonin does not demonstrate any significant difference segregated by liver etiology in the ascites group;but ascitic fluid procalcitonin is elevated significantly in car-diac cirrhosis/miscellaneous subgroup compared to the hepatitis C virus and alcoholic cirrhosis subgroups.CONCLUSION:Procalcitonin in the ascitic fluid,but not in the serum,differentiates between cirrhotic subgroup reflecting the dynamic interplay of ascites,bacterial translocation and the peri-peritoneal cytokine.Bashar M Attar Christopher M Moore Magdalena George Nicolae Ion-Nedelcu Rafael Turbay Annamma Zachariah Guiliano Ramadori Jawed Fareed David H Van Thiel 2014World Journal of Gastroenterology2014,20,9:4

8Hepatocellular carcinoma after Iocoregional therapy:Magnetic resonance imaging findings in falsely negative exams显示文摘AIM:To elucidate causes for false negative magnetic resonance imaging(MRI)exams by identifying imaging characteristics that predict viable hepatocellular carcinoma(HCC)in lesions previously treated with locoregional therapy when obvious findings of recurrence are absent.METHODS:This retrospective institutional review board-approved and Health Insurance Portability and Accountability Act-compliant study included patients who underwent liver transplantation at our center between 1/1/2000 and 12/31/2012 after being treated for HCC with locoregional therapy.All selected patients had a contrast-enhanced MRI after locoregional therapy within 90 d of transplant that was prospectively interpreted as without evidence of residual or recurrenttumor.Retrospectively,2 radiologists,blinded to clinica and pathological data,independently reviewed the pre transplant MRIs for 7 imaging features.Liver explan histopathology provided the reference standard,with clinically significant tumor defined as viable tumor≥1.0cm in maximum dimension.Fisher’s exact test was firs performed to identify significant imaging features.RESULTS:Inclusion criteria selected for 42 patients with 65 treated lesions.Fourteen of 42 patients(33%and 16 of 65 treated lesions(25%)had clinically significant viable tumor on explant histology.None o the 7 imaging findings examined could reliably and reproducibly determine which treated lesion had viable tumor when the exam had been prospectively read as without evidence of viable HCC.CONCLUSION:After locoregional therapy some treated lesions that do not demonstrate any MRI evidence o HCC will contain viable tumor.As such even patients with a negative MRI following treatment should receive regular short-term imaging surveillance because some have occult viable tumor.The possibility of occult tumo should be a consideration when contemplating any action which might delay liver transplant.David Becker-Weidman Jesse M Civan Sandeep P Deshmukh Christopher G Roth Steven K Herrine Laurence Parker Donald G Mitchell 2016World Journal of Hepatology2016,8,16:2
9Evaluation and treatment of internal impingement of the shoulder in overhead athletes显示文摘One of the most common pathologic processes seen in overhead throwing athletes is posterior shoulderpain resulting from internal impingement. 'Internal impingement' is a term used to describe a constellation of symptoms which result from the greater tuberosity of the humerus and the articular surface of the rotator cuff abutting the posterosuperior glenoid when the shoulder is in an abducted and externally rotated position. The pathophysiology in symptomatic internal impingement is multifactorial,involving physiologic shoulder remodeling,posterior capsular contracture,and scapular dyskinesis. Throwers with internal impingement may complain of shoulder stiffness or the need for a prolonged warm-up,decline in performance,or posterior shoulder pain. On physical examination,patients will demonstrate limited internal rotation and posterior shoulder pain with a posterior impingement test. Common imaging findings include the classic 'Bennett lesion' on radiographs,as well as articular-sided partial rotator cuff tears and concomitant SLAP lesions. Mainstays of treatment include intense non-operative management focusing on rest and stretching protocols focusing on the posterior capsule. Operative management is variable depending on the exact pathology,but largely consists of rotator cuff debridement. Outcomes of operative treatment have been mixed,therefore intense non-operative treatment should remain the focus of treatment.Keith T Corpus Christopher L Camp David M Dines David W Altchek Joshua S Dines 2016World Journal of Orthopedics2016,7,12:2
