目的　探讨改良的微拉伸法在同一牙上做平行配对粘接比较的可行性 ,并评价两种新型牙本质粘接剂 (Prime & Bond RNT;Prime one Mirage TM)的粘接效果。方法　选用 15颗拔出的无龋人类磨牙 ,冠部横切暴露牙本质 ,于中央垂直向下开一深约 5 mm的小槽 ,将粘接面分成大致相等的两部分 ,以分别接受两种粘接剂处理。粘接后的标本浸于 37℃的蒸溜水中 2 4小时后分成两组 : 组 (5颗牙 )直接测试粘接强度 ; 组 (10颗牙 )则在粘接强度测试前行 5℃和 5 5℃的冷热循环 2 40 0次。各预备的标本被片切成若干“酒杯”形薄块 (凹槽间最窄处相距约为1.0 m m)供拉伸测试。结果　未经温度循环和经温度循环的两组试件的粘接强度分别为 :Prim e & Bond RNT:42 MPa、 31MPa;Prim e one Mirage TM:6 4MPa、38MPa。双因素方差分析表明 ,此两种粘接剂的微拉伸强度间以及它们各自是否行冷热循环处理的粘接强度间均存在显著性差异 (P0 .0 5 )。回归分析提示 ,以每牙为单位分别得出的这两种粘接剂各自的平均微拉伸强度间存在相关性 ,并具有统计学意义 (r=0 .5 75 ,P<0 .0 5 )。结论　改良微拉伸法可用于比较和评价两种牙本质粘接?

Diagnostic detection with cardiac tomography and resonance of extremely rare coronary anomaly:A case report and review of literature

BACKGROUND The association of two congenital coronary artery anomalies(CAAs) is extremely rare but represents one of the main cause of sudden cardiac death in young athletes. Although coronary angiography(CX-A) is still widely used in childhood, cardiac magnetic resonance(C-MRI) and cardiac computed tomography(C-CT) have recently taken on an increasing diagnostic role in early detection of CAAs and concomitant congenital cardiac *** SUMMARY A healthy 10-year-old male patient was referred to the Radiological Department of our Institution due to no evidence of left coronary artery in echocardiographic examination. With C-MRI was detected marked myocardial trabeculation and was suspected anomalous origin and course of left circumflex(LCx) artery and of left anterior descending(LAD) artery. With third generation Dual Source C-CT192x2-sections(SOMATOM Force, Siemens, Germany) was confirmed anomalous origin of LCx artery from right pulmonary artery associated with anomalous origin of LAD artery from right coronary artery with course in front of right ventricular outflow tract. The patient underwent surgical treatment with reimplantation of the anomalous LCX and LAD arteries into the wall of ascending aorta, with no postoperative complications. The patient remained asymptomatic and follow-up C-MRI scan four months after operation showed complete success of surgery *** This case highlights the diagnostic potential of C-CT and C-MRI in evaluation of CAAs and of cardiac morphology and functionality, with very low radiation dose and without the risks related to invasive procedure.

Are liver nested stromal epithelial tumors always low aggressive?

World Journal of Gastroenterology 2017年第46期23卷 8248-8255页

Nested stromal-epithelial tumor(NSET) is a nonhepatocytic and non-biliary tumor of the liver consisting of nests of epithelial and spindled cells with associated myofibroblastic stroma and variable intra-lesional calcification and ossification, which represents a very rare and challenging disease. Most of the reported cases have been treated with surgery, obtaining a long survival outcome. Here, we report the case of a 31-year-old Caucasian man who underwent surgery at our institution for a large, lobulated, multinodular mass of the right hemi-liver. The histological exam confirmed the diagnosis of NSET. After 6 mo from surgery, a liver recurrence was described and a chemoembolization was performed. After a further disease progression, based on the correlation between the histological features of the disease and those of the hepatoblastoma, a similar chemotherapy regimen(with cisplatin and ifosfamide/mesna chemotherapy, omitting doxorubicin due to liver impairment) was administered. However, infection of the biliary catheter required a dose modification of the treatment. No benefit was noted and a progression of disease was radiologically assessed after only four cycles. The worsening of the clinical status prevented further treatments, and the patient died a few months later. This case report documents how the NSET might have an aggressive and non-preventable behavior. No chemotherapy schedules with a proved efficacy are available, and new data are needed to shed light on this rare neoplasm.
