To explore the role of tissue harmonic imaging(THI) in differentiating hepatocellular carcinoma (HCC), liver metastasis and hemangioma.Methods TOSHIBA SSA-370A ultrasonic system with a 3-to 6-MHz convex transducer (PMV-375AT) was utilized for the study.68 patients(30 cases of HCC, 14 liver metastasis, 24 cases of hemangioma) were examined with fundamental imaging(FI) and tissue harmonic imaging ( THI). Signal-to-noise ratio (SNR), tissue structure parameter:coefficient of variation(CTV) and specific coefficient of variation(CTVs) were calculated, then the tendency of each parameter in every group was evaluated.Results CTV and CTVs within group had no difference, but those between the groups had significant difference(P【0. 05). As a good parameter, CTVs could correctly discriminate HCC, liver metastasis and hemangioma in three groups. It showed that the value of SNR was the highest in hemangioma and the lowest in liver metastasis, and it showed the tendency of increment of the value with a decreased frequ 展开更多

As everybody knows, in learning English, listening, speaking, reading and writing are the major parts. In the process of learning English, the students endeavour to get every sound right, to spell every word correctly and to speak English without making any mistakes. But in real terms it is impossible. Most students don’t realise that making errors is a natural part of the accquisition process. So many students of English are always worrying about making errors. They often ask themselves, ’Why?’ when they make a mistake. In order to find out, let’s divide the subject into three parts for discussion. Everyone knows that most learners insist on a conventional idea about errors in learning.They usually think that making errors is not good. If someone makes a mistake he will be laughed at by the others. In this case, the students are constantly afraid of being laughed at by the others.Then, when they are asked to answer the teacher’s questions, they often 展开更多

An automatic procedure for building a protein polyalanine backbone from guidingalpha-carbon positions is presented here,which is different from a previouslydeveloped’spare parts’approach(Jones and Thirup,1986;Claessens et al.,1989).In our procedure,the geometric restraint of angle N-CA-C is used to generatea list of polypeptide chains,and several filters are used later to select thebest conformer.The most important filter is based upon the Ramachandran scatterplot of mainchain dihedral angles PHI and PSI.Results for all test cases aresatisfactory,with more than 95%of peptide planes correctly reconstructed andthe overall root-mean-square deviation less than 0.5 angstrom compared with therefined X-ray coordinates. 展开更多
