Objective To assess the CT perfusion characteristics of breast diseases. Methods Twenty-two patients with fibroadenoma accompanied with cyst (n=1), other benign diseases (n=5), and carcinomas (n=16) underwent breast CT scan. CT perfusion was performed for breast with cine mode (0.5 s per rotation ) on a multislice CT scanner ,120 kV, 60 mA, 4?5 mm collimation. Contrast injection was done by using 50 ml nonionic contrast agent ( 300 mg I/ml ), at a flow rate of 4 ml/s with a power injector, 5 seconds delay, and data acquisition lasted for 50 seconds. These data were processed on a GE AW 4.1 workstation using perfusion 3 software package, and the mean BF, BV, MTT and PS were measured and statistically analyzed. Results The mean BF, BV, MTT and PS in carcinoma were (33.55? 28.40) ml?min -1 ? 100 g -1 , (5.60?3.08) ml/100 g, (15.37?6.41) s, (18.71?10.42) ml?min -1 ?100 g -1 . The mean BF, BV, MTT and PS in contralateral normal breast of carcinoma were (10.36?9.44) ml?min -1 ? 100 g -1 , (0.70?0.22) ml/100 g, (13.55?7.27) s, (1.54?1.74) ml?min -1 ?100 g -1 . The mean BF, BV, and PS between carcinoma and normal breast were statistically significant (P0.05). The mean BF, BV, MTT and PS in fibroadenoma were (62.57?19.62) ml?min -1 ?100 g -1 , (7.37?1.30) ml/100 g, (11.24?3.34) s, (27.63?3.87) ml?min -1 ?100 g -1 . The mean PS between carcinoma and fibroadenoma was statistically significant (P0.05). The mean BF, BV, MTT and PS in benign lesion were (7.65?10.24) ml?min -1 ?100 g -1 , (1.23?0.97) ml/100 g, (14.94?10.68) s, (1.81?1.72) ml?min -1 ?100 g -1 . The mean BF, BV, and PS between carcinoma and benign lesion were statistically significant (P0.05). Conclusion MSCT perfusion may reflect the features of breast diseases, and provide valuable hemodynamic message. These parameters have a value in diagnosis of breast diseases and are helpful for differential diagnosis.

Objective To investigate the role of CT in the diagnois of superior vena cava syndrome secondary to pulmonary carcinoma. Method Fifty patients with pulmonary carcinoma resulting in SVCS were confirmed by pathological examinations. Relationship between anatomical distribution and gross type of pulmonary carcinoma and modes of pulmonary carcinoma resulting in SVCS were analyzed retrospectively and statistically. Correlation among obstructive degree of SVC, opening of collateral pathway and swelling of chest wall was analyzed retrospectively and statistically. Results For modes of pulmonary carcinoma resulting in SVCS, direct invasion of pulmonary carcinoma was 7 patients, metastasis of lymph node was 16 patients and both of the two was 27 patients.Modes of pulmonary carcinoma resulting in SVCS were different for different gross types of pulmonary carcinoma in different pulmonary lobes ( x2 = 30.012,P ＜ 0.05). On CT appearances of secondary lesions, cases of simple constitution and opening of collateral pathway, simple swelling of chest wall, both of the two and neither of the two were 14 patients, 12 cases, 15 patients and 9 patients in order on CT. With SVC obstruction at different extent,constitution and opening of collateral pathway and swelling of chest wall were different ( x2= 12.881, P ＜ 0.05).Conclusions SVCS resulted from pulmonary carcinoma can be diagnosed by contrast enhanced CT.

Single-supervisor system is the widespread practice for graduates of clinical medicine at present. But in terms of education to clinical medical graduate students, students rotate in the departments of various disciplines for a long time, and there are more rotary department, resulting in some students' unbalanced learning development. Combined with the charac-teristics of the department of hematology, multi-supervisors training model was carried out to the rotating masters of other disciplines when they rotated in hematology department. With supervisor equipment and teaching implementation, we applied the principle of integrating theory with practice and trained students' innovation ability and doctor-patient communication ability. Compared with traditional single supervisor training pattern, multi-supervisors system can effec-tively improve the students' theoretical level, practical skills and comprehensive ability when the clinical medical graduate students rotate in the department of hematology.

Objective To compare the adverse reactions of intranasal and intravenous dexmedetomidine on tracheal extubation during wake up of general anesthesia.Methods One hundred and twenty patients who ASA Ⅰ or Ⅱ grade were divided into four groups (each 30 patients) by random digits table method.The patients in intravenous group were given 0.5 μ g/kg intravenous dexmedetomidine (diluted to 10 ml by 0.9％ sodium chloride,intravenous injection slowly,≥30 s).The patients in intranasal group 1 were given 0.5 μg/kg intranasal dexmedetomidine.The patients in intranasal group 2 were given 0.8 μg/kg intranasal dexmedetomidine.The patients in control group were given intravenous 0.9％ sodium chloride.The systolic blood pressure(SBP),mean arterial blood pressure (MAP),heart rate were compared among groups.Eyes open time and extubation time,the rate of cough and the degree during extubation were compared too.Results The SBP,MAP,heart rate in intravenous group,intranasal group 1 were significantly higher than those in basal state (P ＜ 0.05).The SBP,MAP,heart rate at different time in intranasal group 2 had no significant difference (P ＞ 0.05).The SBP,MAP,heart rate before extubation and after extubation for 3 min in control group were significantly higher than those in intravenous group,intranasal group 1 and intranasal group 2 (P ＜ 0.05).Eyes open time and extubation time among four groups had no significant difference(P ＞0.05).The rate of cough,restlessness and 3 scores of degree before extubation in intravenous group,intranasal group 1 and intranasal group 2 were significandy lower than those in control group [43％ (13/30),50％(15/30),47％(14/30) vs.70％ (21/30); 17％(5/30),23％(7/30),20％(6/30) vs.43％(13/30);53％ (16/30),60％ (18/30),50％ (15/30) vs.80％ (24/30)] (P ＜ 0.05).Conclusions Either intravenous or intranasal dexmedetomidine can effectively prevent the stress reaction during extubation,decrease the degree of restlessness and cough.Intranasal dexmedetomidine(0.8 μ g/kg) is more effective and safe.

ObjectiveTo investigate the postoperative 3D MRI appearances and their evolvement patterns of ACL grafts and bone tunnels at follow-up.Methods There were 26 double bundles ACL reconstructions and 16 single bundle ACL reconstructions,and a total of 56 follow-up 3D MR Imaging.MR images were reconstructed with MPR technique to evaluate grafts,bone tunnels,fixers and associated.complications.Proportions of grafts with hypointensity or hyperintensity and occurrence rates of marrow edema around bone tunnels were calculated respectively among groups of different periods after operation.ResultsThere were 24 grafts of hypointensity and 32 grafts of hyperintensity.Grafts of 2 cases were suspended with cross pins within femoral tunnels,graft of 1 case was suspended with an endobutton within the femoral tunnel,and grafts of other sites were fixed with interference screws.In the three periods as 3 months,6 to 9 months and over 12 months after cruciate ligament reconstruction,proportions of hypointensive grafts were 20/25,0/14 and 4/10 respectively,while proportions of hyperintensive grafts were 5/25,14/14 and 6/10 respectively,occurrence proportions of marrow edema around bone tunnels were 54/54,10/32 and 4/26 respectively.There was 1 tear graft,4 tibial tunnels placed anteriorly with ACL graft impingement on the intercondylar roof,3 femoral tunnels placed anteriorly,and 2 bone tunnels with mismatching interference screws.Conclusion3D MRI can accurately demonstrate the state of ACL grafts,bone tunnels,fixers and associated complications.Intensity of grafts presented a rise and reduce pattern after operation.

Objective To evaluate the value of glycogen phosphorylase isoenzyme BB (GPBB) in the diagnosis of early acute myocardial infarction (AMI). Methods The plasma levels of GPBB were mea-sured by sandwich ELISA in 115 patients with suspected AMI at admission within 6 hours after onset of chest pain and 55 normal healthy subjects. The plasma concent of cardiac troponin-Ⅰ (cTnI), creatine kinase-MB (CK-MB) and myoglobin (MYO) was assayed at the same time by using corpuscle chemiluminescence. The patients were classified retrospectively into AMI group (n = 45) , unstable angina pectoris (UAP) group (n =40) , stable angina pectoris (SAP) group (n = 13) and non-cardiac chest pain (NCCP) group (n =17).The diagnostic validity was evaluated in terms of sensitivity and specificity. Results The diagnostic sensitivity of GPBB for AMI was 64.29 % within 3 hours and 88.89 % within 6 hours after onset of chest pain,which is significantly higher than that of cTnI (28.57 %, 60.00 %) and CK-MB (21.43 %, 64.44 % ). There was no significant difference in specificity among the four markers. The diagnostic accuracy of GPBB within 3hours and 6 hours (80.77 %, 89.57% ) was significantly higher than that of cTnI (61.54%, 81.74% ),CK-MB (50.00%, 75.65%) and MYO (73.08% ,73.91%). Conclusions GPBB seems to be a sensitive and specific biochemical cardiac marker for AMI in the early stage. Its diagnostic accuracy is higher than that of cTnI, CK-MB, MYO.
