AIM To explore the outcomes and the appropriate treatment for patients with moderately severe acute pancreatitis(AP).METHODS Statistical analysis was performed on data from the prospectively collected database of 103 AP patients admitted to the Department of Surgery,Hospital of Lithuanian University of Health Sciences in 2008-2013. All patients were confirmed to have the diagnosis of AP during the first 24 h following admission. The severity of pancreatitis was assessed by MODS and APACHE Ⅱ scale. Clinical course was re-evaluated after 24,48 and 72 h. All patients were categorized into 3 groups based on Atlanta 2012 classification: Mild,moderately severe,and *** and management in moderately severe group were also compared to mild and severe cases according to Atlanta 1992 and 2012 *** Fifty-three-point four percent of patients had edematous while 46.6 % were diagnosed with necrotic AP. The most common cause of AP was alcohol(42.7%) followed by alimentary(26.2%),biliary(26.2%) and idiopathic(4.9%). Under Atlanta 1992 classification 56(54.4%) cases were classified as "mild" and 47(45.6%) as "severe". Using the revised classification(Atlanta 2012),the patient stratification was different: 49(47.6%) mild,27(26.2%) moderately severe and 27(26.2%) severe AP cases. The two severe groups(Atlanta 1992 and Revised Atlanta 2012) did not show statistically significant differences in clinical parameters,including ICU stay,need for interventional treatment,infected pancreatic necrosis or mortality rates. The moderately severe group of 27 patients(according to Atlanta 2012) had significantly better outcomes when compared to those 47 patients classified as severe form of AP(according to Atlanta 1992) with lower incidence of necrosis and sepsis,lower APACHE Ⅱ(P = 0.002) and MODS(P = 0.001) scores,shorter ICU stay,decreased need for interventional and surgical *** Study shows that Atlanta 2012 criteria are more accurate,reduce unnecessa

膜连脱离的内部固定失败的发生从 6% ～ 75% 变化。硬件破裂或移植和膜连混乱复发经常是无征状的，仅仅在一些情况中，操作被要求。当完成前面的骨盆的戒指的解剖减小是技术上不可能的时，这份报告在没有通过的内部固定和忽视的创伤的膜连脱离以后描述二个案例的管理。为膜连没有的内部固定和骨头接枝解剖重新定位被执行。病人完成了好结果并且没在每日的活动期间有疼痛的抱怨。解剖的恢复不应该是在在没有通过的固定以后对待膜连脱离的复发的目的。外科的目的是有骨头 grafting 的前面的骨盆的戒指的静态的固定。

Phonon-assisted tunneling (PhAT) model is applied for explication of temperature-dependent conductivity and I-V characteristics measured by various investigators for graphene nanoribbons and oxides ones. Proposed model describes well not only current dependence on temperature but also the temperature-dependent I-V data using the same set of parameters characterizing material under investigation. The values of active phonons energy and field strength for tunneling are estimated from the fit of current dependence on temperature and I-V/T data with the phonon-assisted tunneling theory.
