Objective To explore the imaging characteristics of hepatic primary leiomyoma.Methods The CT and MR imaging findings of three pathologically proven primary leiomyoma of the liver were analyzed,and the correlation between the imaging features and pathological results was analyzed.Two patients underwent CT scanning.Two patients underwent MRI.Results The lesions appeared hypodense in CT images,and with elongated T_1 time and elongated T_2 time in MRI.One lesion was homogenous both in CT and MRI,with significant homogenous enhancement.The other two lesions were inhomogeneous,with inhomogeneous enhancement in one lesion.All the three lesions had the sign of pseudocapsule.Neither hepatic cirrhosis nor venous tumor emboli were present.Pathological examination showed proliferation of spindle- shaped neoplastic cells and hyperplasia of capillary.One tumor had central hyalinization and another tumor had central necrosis.Conclusion Primary leiomyoma of the liver is one kind of hypervascular tumors with pseudocapsule.CT and MR can provide helpful information to the diagnosis.

Objective Global brain atrophy was reported as an important structural change in Alzheimer's disease (AD), while it has been detected in the older person with normal cognitive function. Therefore, this study was aimed at investigating the difference of the neural metabolites in the left hippocampus (HIP) and left frontal cortex (FC) among patients who showed global brain atrophy but with different cognitive function. Methods The 33 patients with global brain atrophy confirmed by MRI scan, underwent a comprehensively clinical and neuropsychological assessment including mini-mental state examination (MMSE), activities of daily living scale (ADL) and clock drawing test(CDT). According to the diagnostic and statistical manual of mental disorders, fourth edition(DSM-Ⅳ) and Mayo clinic rochester(MCR), 14 patients were diagnosed as AD, 9 patients as amnestic mild cognitive impairment(aMCI), and 10 patients as normal cognition. Every person was taken a cerebral proton magnetic resonance spectroscopy(1H-MRS) scan to measure the levels of n-acetylaspartate(NAA), choline(Cho), myo-inositol(MI) and Creatine(Cr) in the left HIP and the left FC. Results While compared with the group with normal cognition, the ratio of NAA/Cr in the AD group reduced 10.2% in the left HIP and 5.3% in the left FC, and the ratio of Cho/Cr increased 17.5% in the left HIP and 16.7% in the left FC, and the ratio of MI/Cr increased 39.5% in the left HIP and 19.2% in the left FC. The ratio of NAA/Cr of the left HIP in the AD group was lower than that in the aMCI group at the decrease rate of 6.4%, while the ratio of NAA/Cr of the left FC was not significantly different between the two groups. The AD group had higher ratios of Cho/Cr at the increase rate of 9.3% in the HIP and 12.3% in the FC, and higher MI/Cr ratios at the increase rate of 30% in the HIP and 17% in the FC than in the aMCI group. The aMCI group showed significantly lower ratio of NAA/Cr at the decrease rate of 4.1% and higher ratio of Cho/Cr at the increase rate of 7.5% in the left HIP than in the normal cognition group. Conclusions Among patients with global brain atrophy, the decrement of ratio of NAA/Cr in the left HIP and the increment of the ratio of Cho/Cr and MI/Cr are predictive of the progress from aMCI to AD. Moreover, the decrement of ratio of NAA/Cr in the left HIP and the increment of the ratio of Cho/Cr are helpful to distinguish the aMCI and the persons with normal cognition.

Objective To observe the efficacy and safety of vildagliptin combined with acarbose in treating type 2 diabetes. Methods 78 patients with type 2 diabetes were divided into two groups to have additional vildagliptin combined with acarbose or acarbose combined with placebo. The clinical efficacy and adverse reactions after 12 weeks were investigated. Results In the treatment group, FBG, 2 h PG and HbA1C declined after treatment (P < 0.05) and FCP, 2 h CP, FINS and 2 h INS increased (P < 0.05). Compared with the control group, FBG and HbA1c in the treatment group were reduced and owever, FCP, 2 h CP, FINS and 2 h INS were increased more significantly (P < 0.05). There was no difference in the incidence of overall BMI between the two groups (P > 0.05). There were either liver and kidney damage (P > 0.05), nor hypoglycemia. Conclusion Vildagliptin combined with acarbose is superior to Acarbose combined with placebo , and it produced no more untoward effect.

Objectives To investigate the rational treatment strategy of hepatoblastoma (HB) in children. Methods Clinical data and follow-up of 25 children with HB admitted from February 2009 to March 2013 were retrospectively analyzed. Results Twenty-five children with newly diagnosed HB (14 males and 11 females) were enrolled. The median age on diagnosis was 25 months (3-92 months);In 18 of 25 cases with complete resection of the primary tumor, 17 cases survived. Only 1 of 7 cases with incomplete resection survived. The survival rate in children with complete resection of primary tumor is significantly higher than those without complete resection (P<0.05). The survival rate in children of stage I or II is significantly higher than the children of stage III or IV (P<0.05). Conclusions Complete tumor resection is the cornerstone of therapy for long-term disease-free survival in HB patients. Treatment strategy remains to be further improved for children with recurrent and metastatic HB.
