: ObjectiveTo compare the clinical significance of motor unit number estimates (MUNE) and conventional electromyogram (EMG) in the evaluation of neuromuscular disorders. MethodsUnder the model of MUNE or quantity of motor unit potential (QMUP), 53 patients with various neurogenic disorders were tested with EMG at extensor digitorum brevis, thenar, or hypothenar eminence. ResultsFor 8 patients with amyotrophic lateralizing sclerosis, large and long-duration polyphasic potentials were detected in needle electrode EMG tests, and the motor unit numbers reduced. For 45 patients with peripheral neuropathies, few distinctive features could not be detected by needle electrode EMG, but motor unit numbers reduced in 2 patients; spontaneous activities were the only abnormality in the other 2 patients, and there were no obviously abnormal changes in the configuration and size of motor unit potentials and in motor unit numbers; EMG tests revealed neurogenic features and motor unit numbers significantly reduced in the remaining 41 patients. ConclusionConventional EMG and MUNE can work for the diagnosis of neuromuscular disorders, and do better in combination.

Objective To explore the three ultrasonic technologies of two -dimensional ultrasound(2D -US),ultrasonic elastography(UE) and contrast -enhanced ultrasound(CEUS) for the measurement error in breast cancer and the correlation with the expression of ER,PR,VEGF.Methods 50 patients with breast cancer were meas-ured by 2D -US,UE,CEUS preoperatively,and the pathological specimen were measured postoperatively.Then used the immunohistochemistry to detect the expression of ER,PR,VEGF in tumor,and analyzed the correlation with the measurement errors.Results The results of differences between 2D -US,UE,CEUS and pathology were respectively as follows:( -0.59 ±-0.34)cm,( -0.20 ±-0.14)cm,( -0.40 ±-0.31)cm,and the differences were statistically significant(F =20.497,P <0.001).The positive expression rate of ER and PR was high if the difference between UE and 2D -US was less than or equal to 0.44cm.And the positive expression rate of VEGF was low if the difference between CEUS and 2D -US was less than or equal to 0.19cm.Three ultrasonic technologies in the measurement of breast cancer were different,the trend of difference between UE and 2D -US was smaller if the ER and PR were positively expression,and the trend of difference between CEUS and 2D -US was bigger if the VEGF was positively expression.Conclusion There is correlation between different immunohistochemical expression of breast cancer with measurement error in three different ultrasonic imaging technologies.The results suggest that the molecular pathology difference of breast cancer can impact on ultrasonic imaging,which contributes to know the reason and regulation of measurement error in different ultrasonic imaging technology.

Objective:
To investigate the clinicopathologic features of cardiac myxofibrosarcomas.
Methods:
The clinical data, pathomorphologic and immunohistochemical features were evaluated in five cases of cardiac myxofibrosarcoma collected from January 2009 to December 2014, with relevant literature review.
Results:
Five patients with cardiac myxofibrosarcoma, including four women and one man [age range 39-61 years; mean (50.4±9.0) years] were included. All tumors were broadbased and located mainly in the left atrium, with one case extending through the atrial wall and pericardium to the left lower lung lobe. The morphological grade was low in one case, intermediate in one, and high in three. Using Fédération Nationale des Centres de Lutte Contre le Cancer (FNLCC) grading system, one case was grade 1 and four cases were grade 2. Immunohistochemical analysis revealed diffuse and strong expression for vimentin in all cases. Smooth muscle actin and muscle specific actin were variably expressed. Complete tumor excision was performed in one case, and tumor debulking was performed in the other four cases. Clinical follow-up was available in three cases. One patient with en bloc excision of the tumor mass survived 13 months and the other two with tumor debulking died one month after surgery.
Conclusions
The most common location for cardiac myxofibrosarcoma is the left atrium. Some myxofibrosarcoma may be histologically bland and misdiagnosed as myxoma due to histological similarities. Thus caution should be exercised in their microscopic differentiation. Precise imaging, multidisciplinary approach and adequate initial surgery may contribute to improving the clinical outcomes of myxofibrosarcoma.

OBJECTIVETo improve the diagnostic accuracy of fetal pulmonary venous abnormalities through the analysis of the fetal pulmonary vein anatomy.
METHODS234 cases of congenital cardiac abnormalities were detected by echocardiography during pregnancy in An Zhen Hospital, Capital Medical University from May 2010 to August 2015. Autopsy was then performed. The type of fetal pulmonary venous malformation, cardiac abnormalities, systemic venous malformations, and other internal organs deformities were documented.
RESULTSThere were ninteen cases of pulmonary venous malformations among the 234 cases of fetal congenital heart disease. These included two cases of congenital pulmonary venous hypoplasia (CPVH) or atresia, four cases of partial anomalous pulmonary venous drainage (PAPVD), seven cases of total anomalous pulmonary venous drainage (TAPVD), five cases of atresia of common pulmonary vein (CPV), one case of congenital pulmonary venous hypoplasia with total anomalous pulmonary venous drainage. There were eleven cases with single ventricle, eight cases with right aortic arch, seven cases with single atrium and six cases with pulmonary valve stenosis. Eleven cases had pulmonary hypoplasia and nine cases had abnormal spleen.
CONCLUSIONSThere are many variations in pulmonary venous abnormalities associated with severe and complex cardiac abnormalities and internal organs malformation. Care should be exercised during autopsy examination to look for all branches of the pulmonary vein.
