The main feature of acute steroid-resistant rejection (ASRR) after liver transplantation is a lack of response to steroids.Although some effective immunosuppressants are available,there is no uniform treatment presently available.This paper will focus on exploring the mechanism of ASRR and formulating individually approached strategies.

Objective:To study the radiation dose rate around patients underwent renal dynamic imaging of SPECT with 99Tcm-DTPA, so as to provide the basis for ensuring the radiation safety of the surrounding environment and the general public.Methods: 109 patients who underwent renal dynamic imaging were enrolled in this study, and the radiation dose rates of different time and different distance after 99Tcm-DTPA was injected patients were measured. And then, the changes of dose rate following time and distance were analyzed. Results: At the 0.5h, 1h, 2h, 3h, 6h, and 7h after radiopharmaceuticals were injected patients underwent renal dynamic imaging, the radiation dose rates were 0.76-8.86 μSv/h, 0.68-7.27 μSv/h, 0.57-4.52 μSv/h, 0.56-3.90 μSv/h, 0.23-2.07 μSv/h and 0.21-1.05 μSv/h, respectively, between 0.5 m and 4 m away from patients. At 24h after radiopharmaceuticals were injected, all of radiation dose rates at different distances around patients were same with background values.Conclusion: The radiation dose rates around patients underwent renal dynamic imaging will rapidly decrease with the increasing of time and distance. At 24h after radiopharmaceuticals were injected, all of radiation dose rates at different distances away from patients were same with background values.

Objective To investigate the clinical application of subaxillary curved mini-incision thoracotomy in thoracic operations. Methods Through a subaxillary curved mini-incision between the latissimus dorsi muscle and the serratus anterior muscle (length of incision, 8~14 cm), thoracic operations were performed in 65 patients with thoracic diseases, including pneumothorax or hemopneumothorax (13 patients), pulmonary benign tumor (23 patients), mediastinal tumor (4 patients), and esophageal benign or malignant tumor and cardiac cancer (25 patients). Results All the patients were successfully operated on. No surgery-related deaths occurred. The incidence of complications was 6.2% (4/65), including pleural effusion in 1 patient, pulmonary infection in 2 patients, and anastomotic leakage of esophagogastrostomy in 1 patient.Conclusions Subaxillary curved mini- incision thoracotomy, characterized by minimal invasion, little blood loss, mild influence on cardiopulmonary functions, quick recovery, and good cosmetic outcomes, is an ideal option for the treatment of thoracic diseases.

The development of community-based rehabilitation (CBR) needs to improve to meet the change of environment during the period of 12th Five-year Plan. The problems of CBR development included 3 major contradictions: administration of CBR and marketization of medical services; professionals demand of CBR and their professional development; and the demand of CBR and capacity of services. It is necessary to establish some market-oriented CBR project, pay attention to professional development, and promote the capacity of the community rehabilitation agencies.

This paper selects the bag-type infusion sets for single use as samples, which are produced by different manufacturers and based on the ethylene oxide sterilization. The ethylene oxide sterilization residues in different parts of samples are detected by colorimetric analysis. Combined the comparison of the ethylene oxide residues testing results in the different parts of the same sample with the actual situation in clinical use, more reasonable sampling positions are found to detect the ethylene oxide sterilization residues. The result of this experiment will play a guiding role in the detection of the actual samples.

Objective To construct a adenovirus vector containing human NRP-1 gene and 3Flag gene to interaction between tumor and interstitial cell.Methods Plasmid containing NRP-1 gene was digested by AgeⅠand NheⅠ restriction endonuclease.Then the DNA was ligated into linearized pDC315-3Flag vector.After having been constructed,the pDC3 1 5-NRP-1-3 Flag plasmid was co-transfected with framework plasmid pBHGlox△E1 , 3Cre into HEK 293 cells to obtain the homologous recombinant adenovirus,which was then amplified and purified its titer tested.Expression of NRP-1 protein was detected using Western blot.Results Polymerase chain reaction and sequencing analysis confirmed that the shuttle plasmid pDC3 1 5-NRP-1-3 Flag and design were consistent. Cytopathic effect was observed by inverted phase contrast after transfecting HEK2 9 3 cells with shuttle plasmid pDC315-NRP-1-3Flag.95-130 ku was detected by Western lot after transfecting HEK293 cells with shuttle plasmid pDC315-NRP-1-3Flag and recombinant adenovirus,the size being consistent with the NRP-1-3Flag fusion protein (104 ku),with a titer of 2.00E+11PFU/mL.Conclusion The recombinant adenovirus vector for human NRP-1 gene was successfully constructed expressed in HEK 2 9 3 cells.

ObjectiveTo summarize the one-year follow-up clinical result of patients undergoing Endoscopic vein harvest (EVH) technology to collect greater saphenous vein( GSV )in coronary artery bypass operation (CABG),and to assess the related factors influencing the outcome.Methods248 patients underwent off-pump coronary artery bypass grafting (OPCAG) from May 2009 to May 2010.Among these patients,136 patients with coronary artery disease received EVH technology to gain GSV,and 112 patients received conventional open vein harvesting (OVH).Then 71 EVH (group 1 ) patients and 64 OVH ( group 2 ) patients had one-year follow-up analysis.We compared and evaluated the data of two groups about operation information,lower limb wound complication,bridge blood vessels patency rate,and psychologic status.ResultsThe date of wound surface size,wound healing and appearance,wound infection rate,the second debridement rate and the overall lower limb wound complication rate show that EVH was better than OVH.After one-year follow-up,we contrasted the patency rate of bridge blood vessels between two groups.The patency rate of arterial bridge blood vessels was 96.8% ( venous bridge blood vessels was 85.7% )in group of EVH when we followed up 63 patients;while the patency rate of arterial bridge blood vessels was 94.9% ( venous bridge blood vessels was 86.4% ) in group of OVH that we followed up 59 patients.We compared the outcome between two groups,and found that there were no statistical significance in angina recurrence rate,patency rate of venous graft and patency rate of arterial graft.But the psychologic status was different,the EVH group was better than OVH group.ConclusionCompared to OVH,EVH technique has more advantages.Through taking a more secure method in the collection process of the bridging vein material,EVH group also maintained a satisfactory one-year graft patency rate.
