A 61-year-old male was referred to our hospital with a three-month history of persistent epigastralgia and right hypochondralgia. Initial examination revealed a fist-size mass at the epigastric fossa. Ultrasonography showed a hemangioma and a mosaic echoic lesion in the ventromedian with poor blood-flow signal and linear hyperechoic part inside, and a clear border to the surroundings. Dynamic computed tomography revealed a highly enhanced effect from the portal-venous phase continuing to the equilibrium phase. t1-weighted gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced image revealed a high intensity effect at the early phase that continued to the next phase. On the other hand, it contained a low intensity area by a fat suppression of that image. In addition, a t2-weighted image did not show a high intensity effect. Laparotomy was performed on the second day of hospitalization. the tumor had arisen from the ligamentum teres of the liver, and no metastasis or invasion of other organs was noted. It consisted of a lipid component of mature adipocytes and a fibrous component of deep dyeing pleomorphic or multinuclear atypical stromal cells. Immunohistochemical study of the atypical stromal cells demonstrated that they were positive for MDM2 and CDK4. A pathological diagnosis of atypical lipomatous tumor(ALt) was made, and the patient was discharged on the eighth day following the procedure. At the 6-mo follow-up dynamic Ct, the patient was free of recurrence or metastasis. We experienced a patient with ALt in the ligamentum teres of the liver. this case suggests the need for a careful and detailed examination when encountering patients presenting with a mass; when neoplastic lesion is confirmed by image inspection, we should thoroughly investigate, including further image investigations and pathologic examination. the latter is the most important.

Eating disorders are an important cause of physical and psychosocial disturbances. Gastrointestinal complications in eating disorders are common and include pancreatitis and superior mesenteric artery syndrome (SMAS). However, only two patients who simultaneously suffered from both SMAS and pancreatitis in the setting of an eating disorder have ever been reported in the literature. We describe here a patient with eating disorder not otherwise specified (ED-NOS) who exhibited both SMAS and pancreatitis concomitantly. An 11-year-old boy with ED-NOS had presented with the sudden onset of recurrent bilious vomiting, abdominal distension and abdominal pain. Laboratory and imaging studies revealed that the patient had SMAS and acute pancreatitis. Gastric decompression and intravenous infusion of fluids promptly improved his abdominal symptoms and laboratory data. this is the first case report of a patient with ED-NOS who simultaneously suffered from SMAS and pancreatitis in the pediatric literature. Since SMAS and pancreatitis can both cause patients to be severely ill, these diseases should be considered in patients with eating disorders who exhibit abdominal symptoms such as vomiting or abdominal pain.

We retrospectively evaluated the efficacy and safety of the combination drug piperacillin/tazobactam (PIPC/tAZ) in comparison with those of fourth-generation cephalosporins (4th Cephs) as initial empirical treatment in hematological malignancies patients with febrile neutropenia (FN). Among 200 patients assessed in this study, 49 had received PIPC/tAZ and 151 4th Cephs. Patient background characteristics were comparable between the two treatment groups. the overall efficacy rate in those receiving 4th Cephs and PIPC/tAZ was 57.0% (86/151 patients) and 59.2% (29/49 patients), respectively, with no significant difference detected between the two treatment regimens (P = 0.78). treat-ment did not need to be discontinued or interrupted due to development of adverse drug reactions in any of the patients. therefore in this study the efficacy and safety of PIPC/tAZ as initial antimicrobial treatment for FN in patients with hematological malignancies were not inferior to those of 4th Cephs. Based on the preliminary data obtained in this study, we propose to conduct a multicenter, prospective, controlled study to compare PIPC/tAZ versus CFPM given as empirical antimicrobial treatment against FN in patients with hematological malignancies.

Since two asymmetric centres are usually present in the bisbenzylisoquinolines,the circular dichroism is known to be an important method to elucidate their *** studied the relationships of the CD spectra with the stereochemistry of synthetic RR-(1),SS-(2),RS-daurisoline(3) and SR-daurisoline(4).By comparision of the CD spectrum of natural daurisoline(1)from Menis- permum dauricum(Menispermaceae)with those of synthetic enantiomers,the absolute configuration was established as RR-daurisoline(1).

通过反演震源机制数据,得到了东日本大地震前后日本东部内陆地区的应力场。地震前,在东北部(tohoku),σ1轴呈EW方向,但在关东-东部(Kanto-Chubu)地区则呈NW-SE方向。地震后,在tohoku北部和靠近磐城市(Iwaki City)的tohoku东南部,应力场发生了变化,主应力取向大致等同于与地震相关的静应力变化取向。这说明地震前这些地区的差应力值小于1MPa。在tohoku中部,虽然地震后加载的应力取向几乎逆转,但其应力场没有发生变化,说明那里的差应力值大大超过1MPa。在Kanto-Chubu,地震后加载了与背景应力方向近乎相同的应力,且应力场没有发生预期的变化。这可能就是Kanto-Chubu地区高地震活动水平的诱因。
