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.

Objective To develop a method to produce leukoreduced platelet concentrates(LR-PCs) from pooled buffy coats in additive solution(a mixture of solutions for medical use).Methods LR-PCs were made from 6 pooled buffy coats(12 whole-blood units) and 220g additive solution,including 90% multiple electrolytes injection solution,8% ACD-A and 2% 50g/L NaHCO3 injection solution.After centrifugation,the PCs were leukoreduced with a filter and stored in a 600ml platelet storage bag.LR-PCs were prepared in a closed system.Results Routinely produced LR-PCs(n=30) contained(2.96?0.31)?1011 platelets with a volume of(270? 32)ml.The WBC and RBC count were(1.3?0.2)?106 and(5.8?1.1)?109 per unit,respectively.The CD62P expression was(22.5? 10.6)%.After 8-day storage,the in vitro quality of LR-PCs,including pH,hypotonic shock response(HSR) and CD62P expression were 7.14?0.04,(54.0?8.2)% and(45.7?13.8)%,respectively.Conclusion In terms of the in vitro quality of LR-PCs,the method of preparing LR-PCs from pooled buffy coats in mixing solutions is feasible.

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.

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.

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.

The study is aimed to investigate the effect of lamivudine on growth and metabolism of three intestinal characteristic bacteria (namely, Bifidobacterium adolescentis, Escherichia coli and Shigella dysenteriae). The growth condition of the three bacteria was quantitatively evaluated by microcalorimetry with four characteristic parameters of the thermal power-time curves, including the growth rate constant (k), thermal power (p), time to peak (t) and calorific value (Q). The results showed that the IC50 value of lamivudine on B. adolescentis was 200 microg x mL(-1), and the IC50 values of lamivudine on S. dysenteriae and E. coli were higher than 3 000 microg x mL(-1) and 6 000 microg x mL(1), respectively. Therefore, lamivudine made different inhibitory effects on the three bacteria, in which the B. adolescentis was most susceptible to lamivudine. This work showed that taking lamivudine chronically is likely to affect the balance of good flora in the intestinal tract, and might increase endotoxin release, leading to inflammation and disease progression in hepatopathy.

Methods A prospective,multicenter and open-label clinical trial was conducted from March to October 2001.A total of 33 patients [20 men and 13 women; age range,18-63 years;mean age,(42.6?11.6) years] who received first kidney allograft were enrolled.Thirty-two cases had panel-reactive antibody

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.
