Mesenchymal hamartomas of the liver(MHLs) in adults are rare and potentially premalignant lesions, which present as solid/cystic neoplasms. We report a rare case of orthotopic liver transplantation in a patient with a giant MHL. In 2013, a 34-year-old female sought medical advice after a 2-year history of progressive abdominal distention and respiratory distress. Physical examination revealed an extensive mass in the abdomen. Computed tomography(CT) of her abdomen revealed multiple liver cysts, with the diameter of largest cyst being 16 cm × 14 cm. The liver hilar structures were not clearly displayed. The adjacent organs were compressed and displaced. Initial laboratory tests, including biochemical investigations and coagulation profile, were unremarkable. Tumor markers, including levels of AFP, CeA and CA19-9, were within the normal ranges. The patient underwent orthotopic liver transplantation in November 2013, the liver being procured from a 40-year-old man after cardiac death following traumatic brain injury. Warm ischemic time was 7.5 min and cold ischemic time was 3 h. The recipient underwent classical orthotopic liver transplantation. The recipient operative procedure took 8.5 h, the anhepatic phase lasting for 1 h without the use of venovenous bypass. The immunosuppressive regimen includedintraoperative induction with basiliximab and high-dose methylprednisolone, and postoperative maintenance with tacrolimus, mycophenolate mofetil, and prednisone. The recipient's diseased liver weighed 21 kg(dry weight) and measured 41 cm × 32 cm × 31 cm. Histopathological examination confirmed the diagnosis of an MHL. The patient did not experience any acute rejection episode or other complication. All the laboratory tests returned to normal within one month after surgery. Three months after transplantation, the immunosuppressive therapy was reduced to tacrolimus monotherapy, and the T-tube was removed after cholangiography showed no abnormalities. Twelve months after tran

Creation of Bielectron of Dirac Cone: The Tachyon Solution in Magnetic Field

LepI is an S-adenosylmethionine（SAM）-dependent pericyclase that catalyses the formation of 2-pyridone natural product leporin C. Biochemical characterization has shown that LepI can catalyse stereoselective dehydration to yield a reactive（e）-quinone methide that can undergo bifurcating intramolecular Diels–Alder（IMDA） and hetero-Diels–Alder（HDA） cyclizations from an ambimodal transition state, as well as a [3,3]-retro-Claisen rearrangement to recycle the IMDA product into leporin C. Here, we solve the X-ray crystal structures of SAM-bound LepI and in complex with a substrate analogue（the product leporin C） and a retro-Claisen reaction transition-state analogue to understand the structural basis for the multitude of reactions. Structural and mutational analysis reveals how nature evolves a classic methyltransferase active site into one that can serve as a dehydratase and a multifunctional pericyclase. Catalysis of both sets of reactions employs H133 and R295, two activesite residues that are not found in canonical methyltransferases. An alternative role of SAM, which is not found to be in direct contact with the substrate, is also proposed.

Schrödinger equation for pair of two massless Dirac particles when magnetic field is applied in Landau gauge is solved exactly. In this case, the separation of center of mass and relative motion is obtained. Landau quantization ε = ±B/?l for pair of two Majorana fermions coupled via a Coulomb potential from massless chiral Dirac equation in cylindric coordinate is found. The root ambiguity in energy spectrum leads into Landau quantization for bielectron, when the states in which the one simultaneously exists are allowed. The tachyon solution with imaginary energy in cooper problem (ε 2 e continuum symmetry of Dirac equation allows perfect pairing between electron Fermi spheres when magnetic field is applied in Landau gauge creating a cooper pair.

背景：他汀类药物既可降低致动脉粥样硬化脂蛋白，也可降低心血管病的发病率和死亡率。然而，其最佳降脂方案和目标值仍未确定。目的：比较强化降脂和中度降脂方案对冠状动脉粥样斑块大小及其进展的影响。设计、地点和病例：双盲、随机和有效对照的多中心试验(积极降脂逆转动脉粥样硬化[Reversal or Atherosclerosis with Aggressive Lipid Lowering，ReVeRSAL])，试验于美国34个社区和三级保健中心对应用两种不同他汀治疗18个月的患者进行了疗效比较。用血管内超声测量动脉硬化的进展。从1994年7月至2001年9月，654例患者随机接受研究药物；其中502例在基线时和治疗18个月后，具有可用的血管内超声检查资料。干预：患者随机接受中度降脂(40mg普伐他汀)方案或强化降脂(80mg阿托伐他汀)方案。主要观察指标：一级疗效指标是动脉粥样斑块体积百分比变化(随诊与基线之间的差值)。结果：两组平均基线低密度脂蛋白胆固醇(LDL-C)水平是150．2mg／dL(3．8mmol／L)。治疗后，普伐他汀组LDL-C降至110mg／dL(2．85mmol／L)，阿托伐他汀组降至79mg／dL(2．05mmol／L)(Pen血管段斑块体积变化(P<0．01)。与基线比较，一级终点冠状动脉粥样硬化进展的发生率普伐他汀组为2．7％(95％CI，0．2％～4．7％；P=0．001)。阿托伐他汀组无冠状动脉病变进展发生(-0．4％；95％CI，-2．4％～1．5％；P=0．98)。结论：对于冠心病患者，与普伐他汀比较，阿托伐他汀强化降脂治疗可减慢冠状动脉粥样硬化的进展。与基线比较，阿托伐他汀组动脉粥样斑块负荷无变化，而普伐他汀治疗组则显示冠状动脉粥样硬化进展。这些差异可能与阿托伐他汀在降低致动脉粥样硬化脂蛋白和C-反应蛋白方面的作用有关。

Objective: To clarify the rate of major intra-operative and post-operative complications experienced during excisional surgery for endometriosis. Design: Prospective multi-centre observational study set in two University teaching hospitals and three private hospitals in Sydney, Australia. All consecutive subjects undergoing laparoscopic excisional surgery for minimal to severe endometriosis were recruited (790 subjects). Complications were recorded intra-opera- tively or post-operatively on a secure computerised patient database. Major intra-and post-operative complications i.e. inadvertent visceral or vascular injury or other complications directly related to surgery that either significantly prolonged the operating time, delayed discharge or necessitated re-admission. Results: Seven hundred and ninety subjects were recruited over a 3-year period. Seven major complications were experienced (8.8/1000); four bowel injuries, one cystotomy, one ureteric transection, and one major vascular injury. All visceral or vascular injuries were diagnosed prior to completion of the surgery. No significant longterm sequelae were experienced. Conclusion: The incidence of major complications in this study of 8.8/1000 compares favourably with other similar reports. In view of the potential symptom relief obtained, the authors continue to believe the benefits of such surgery significantly outweigh the risks of subsequent operative-related morbidity.

The effects of fixation drying conditions on fixation rates and chemical leachab ility were investigated with CCA-C treated red pine (Pinus koraiensis Sieb. )and southern pine specimens at a retention of 6 4 kg·m -3 , and under 11 post-treatment schedules ra ng ing from 50～70℃ and 5 different relative humidity conditions. These samples w e re monitored by expressing residual liquid and analyzing it for hexavatent chrom ium content. Samples were subjected to AWPA e11-97 (AWPA 1997) standard leachi n g tests after fixation. Generally, red pine fixed slightly faster than southern pine for most fixation conditions. High temperature, high humidity, fixation co nditions during the fixation/drying schedules resulted in faster fixation and lo wer leaching of chromium and arsenic elements compared to low humidity condition s. Copper leaching showed no significant difference under 11 fixation /drying co nditions for both species. All of the CCA components were leached significantly more in red pine than southern pine. Further work is needed to examine the effec ts of different fixation/drying conditions on leaching from full\|size samples a n d to optimize dry/wet bulb depression for fixation/drying of CCA treated lumber.
