Objective To assess the role of dynamic contrast-enhanced MRI for diagnosis and differential diagnosis of prostatic cancer. Methods Six volunteers, 32 patients with benign prostatic hyperplasia and 13 patients with biopsy-proven prostatic cancer underwent MR imaging. Dynamic MR with Gd-DTPA (gadolinium-diethylene triamine pentaacetic acid) bolus enhancement was performed followed by post-contrast T 1-weighed imaging. The signal intensive value in dynamic MRI was measured and calculated to draw the time-signal intensity curve of normal peripheral zone, prostatic cancer and benign hyperplasia. Results In dynamic MRI, the normal peripheral zone were enhanced mildly and slowly. The lesion enhancement of benign prostatic hyperplasia in 32 patients were obvious in early phase (60 s) and strengthened gradually, and then went to decrease in late phase (240 s) after peak value. The lesions in 9 of 13 cases with prostate cancer were enhanced obviously in early phase (60 s) and washed out rapidly in late phase, and the peak value was located on early phase. Conclusions In dynamic MRI, the enhancement of normal peripheral zone, prostate cancer and benign hyperplasia were different significantly. Dynamic MRI was very useful in the diagnosis and differentiation of prostate cance.

Objective To modify the techniques for establishment of an abdominal working heart transplantation model in rats and to sum up the key factors to success.Methods A total of 180 12-week old Brown Norway rats ( donor) and Lewis rats ( recipient) were used in this study:50 BN rats and 50 Lewis rats for pilot experiment, and 40 BN rats and 50 Lewis rats for the formal experiment.The rat model of working heart heterotopic transplantation was adopted and estab-lished by Wiedemann’ s mode.We transplanted the heart from BN rats to Lewis rats and analyzed the survival rate, causes of death and histological changes of the heart ( HE staining) in this experiment.Results After exercise and modification, the survival rate was increased to 77.5%, and the mean total duration of operation was 71 ±11 min, and the mean ische-mic time of the donor hearts was 34 ±5 min.Histological examination ( HE staining) of the cardiac allograft showed a mild inflammatory cell infiltration in the graft at 24 h after transplantation, indicating that the model was reliable.Conclusions A variety of factors may affect the final operation success rate in the establishment of this heart transplantation model.A-mong them, the major affecting factors include: healthy animals, donor heart protection, rapid and effective vascular su-ture, and postoperative animal management.

BACKGROUND:In recent years, calcium alginate dressing has been widely used in surgical hemostasis, traumatic hemostasis, postoperative nasal hemostasis and puncture site hemostasis,etc.; however, there are few reports on their hemostatic mechanisms. OBJECTIVE: To preliminarily study the hemostatic mechanism of calcium alginate dressing. METHODS: Human anticoagulant blood was respectively dropped on sodium alginate dressing, nasopore dressing and medical cotton gauze. After 2 minutes, the interaction between materials and blood was observed at the room temperature using scanning electron microscopy. Calcium alginate dressing, nasopore dressing and medical cotton gauze were added in human red blood cel suspensions respectively. After 15 minutes, the interaction between materials and red blood cels was observed using scanning electron microscopy. The red blood cels were suspended by different concentrations (10, 5, 2.5 g/L) of alginate dressing extracts. The erythrocyte sedimentation rate was observed at different time points (30, 60, 120 minutes). Platelets rich plasma was incubated with different concentrations (10, 5, 2.5 g/L) of alginate dressing extract at 37℃, then CD62P positive platelet percentage was measured by flow cytometry after 10 minutes of incubation. RESULTS AND CONCLUSION: Dense fibrin network was formed after calcium alginate dressing contacting with an anticoagulant. A large number of blood cels were recruited. There were only a smal amount of red blood cels and platelets adhesion in the nasopore dressing and medical cotton gauze groups. After the calcium alginate dressing interacting with red blood cels, red blood cel deformability was visible, with a pseudopodia-like change. The red blood cel morphology was unchanged in the nasopore dressing and medical cotton gauze groups. The calcium alginate dressing extract dose-dependently and time-dependently increased the red blood cels aggregation, comparative differences between groups was statisticaly significant(P < 0.01). The calcium alginate dressing extract dose-dependently enhanced the CD62P positive platelet percentage, comparative differences between groups was statisticaly significant (P< 0.01). These results demonstrate that calcium alginate dressing promotes hemostasis and coagulation process by releasing of calcium ions, causing red blood cel aggregation and deformation and activating platelets.

Objective To establish a porcine allogeneic left lung orthotopic transplantation model to closely simu-late human lung transplantation.Methods Twelve Huanjiang mini-pigs were used as donors and 12 Bama mini-pigs as recipients.The left lung orthotopic transplantation was completed by the left fourth intercostal thoracotomy.At 1 h, 2 h, 4 h, 6 h, 12 h after transplantation, the left and right pulmonary artery pressure were measured, the left and right pulmonary vein blood gas was analyzed, and samples of the left and right lung tissues were taken to determine the water content and for pathological examination.Results All animals survived, and the transplanted pulmonary vein blood PaO2/FiO2 and PAP were rised along with the prolonged postoperative time, compared with those of the recipient normal lung showing a signifi-cant difference (P<0.05).With the pass of time, there were increasing edema, inflammatory cell infiltration, RBC ooze, thickening of alveolar wall in the transplanted lung tissue, and some alveolar lumen occlusion and lung tissue consolidation. The water content of the transplanted lung tissue was increased significantly compared with that in the recipient lung tissue ( P<0.05 ) .Conclusions The established method in this study provides an ideal animal model for research on lung transplantation ischemia-reperfusion injury and immune rejection mechanism.

Objective To investigate expressions of phosphorylated c-Jun N-terminal kinase (p-JNK)and P38 mitogen-activated protein kinase(p-P38MAPK)in psoriasis vulgaris lesions. Methods Tissue specimens were obtained from lesions of 30 patients with psoriasis vulgaris and normal skin of 30 healthy human controls. An immunohistochemical study and Western-blot analysis were performed to measure protein expressions of p-JNK and p-P38MAPK in these skin specimens. Results As the immunohistochemical study showed, the expressions of p-JNK and p-P38MAPK(expressed as the average optical density [AOD]value for targeted proteins)were significantly higher in psoriasis vulgaris lesions than in normal skin tissues (p-JNK: 0.663 ± 0.016 vs. 0.333 ± 0.009, t = 44.869, P < 0.001; p-P38MAPK: 0.436 ± 0.011 vs. 0.306 ± 0.010, t = 21.913, P < 0.001). Western-blot analysis also showed increased protein expressions of p-JNK and p-P38MAPK in psoriasis vulgaris lesions compared with normal skin tissues (t = 20.477, 165.084, respectively, both P <0.05). Conclusion The activation of JNK and P38MAPK may be involved in the overproliferation of epidermal cells in psoriasis vulgaris lesions.
