Objective To observe the effects of intrathymic islet transplantation or renal subcapsule islet transplantation on the graft survival.Methods C57BL/6 mice were used as recipients and BALB/c as donors The recipients receiving intrathymic or renal subcapsule islet transplantation were divided into simple transplantation groups and the group intraperitoneally receiving rabbit antithymocyte serum(ATS) at the time of islet transplantation.Results The median survival time (MST) of simple intrathymic allografts were 19.5 days,longer than that of allografts implanted beneath the renal capsule.Administration of ATS at the time of islet transplantation delayed rejection of islets transplanted to the renal subcapsute(MST,43.0 days),and intrathymic allografts were superior(MST,93.8 days).Six of 8 intrathymic grafts with administration of ATS survived permanently.especially a state of donor-specific unresponsiveness was induced.Conclusion The thymus may be an immunoprivileged site for islet transplantation and may play an important role during the induction of immune tolerance.

Objective To probe into urban residents' mental health knowledge awareness in Jingmen city. Methods By means of self-compiled questionnaires, 563 community residents were surveyed about their mental health knowledge and access to it. Results For mental health- care knowledge, community residents scored a total of (42.52±8.79), among which, (15.34±3.25) points for relevant causes,(12.23±4.89) points for corresponding symptoms, and (14.92±4.26) for health behavior. Such aspects would affect a resident's awareness of mental health knowledge as the resident's education background,marriage and chronic diseases. Radio and television (48.3%), newspapers and magazines (41.4%), hospital expert advice (39.8%), and community medical services (36.1% ) were considered the better access to mental health knowledge. Conclusions Residents had considerably inadequate knowledge of mental health. Therefore, a variety of health- care education activities should be carried out to improve residents'mental health knowledge.

Objective To study the molecular mechanisms of hepatoeyte regeneration following different cold preservation (CP) durations after rat partial liver transplantation. Methods Mate inbred Lewis rats were used as donors and recipients. Donor liver was kept in 4℃ UW solution for 1 h (coldisehemia 1 h group, CI 1 h group), 8 h (CI 8 h group) and 16 h (CI 16 h group) and then implantedorthotopieally. 50% liver graft transplantation model was established by ligating the left portion ofmedian lobe, left lateral lobe and caudate lobe with 3-O silk suture prior to reperfusion. Survival rate ofeach group and hepatoeyte regeneration were recorded after grafting. Reverse transcription-polymerasechain reaction was used to detect the expression of IL-6 and TNF-α in the liver tissues. Western blotanalysis was done to measure STAT3 activation in the liver. Immunohistoehemistry was conducted toanalyze the expression of cyclin D1 and hepatocyte replication with BrdU uptake in the graft. ResultsOperative success rate in all groups was 100%. Compared with CI 1 h group, the TNF-α and IL-6expression (F=67.45 for TNF-a comparison, P<0.05 and F=287.73 for IL-6 comparison,P<0.05 respectively) in 8 h CI and 16 h CI groups was markedly increased after partial grafttransplantation. STAT3 activity in 8 h C1 and 16 h C1 groups was also significantly increased ascompared with that in 1 h CI group. Cyclin D1 expression in 8 CI group was demonstrated withcytoplasmic and nuclear staining at 24 h after transplantation. Grafts in 16 h CI group showed largeareas with no cyclin D1 expression. Number of hepatocytes with BrdU positively stained neclei in 8 hCI group was more than that in 16 h C1 group at 24 h after transplantation (t=19.40, P<0.05).Conclusion Hepatocytes regeneration was present following rat partial transplantation in the graftspreserved for limited time, which may be regulated by TNF-α/IL-6' STAT3/ Cyelin D1/DNAsynthesis pathways; Hepatocytes could not respond to early signals for liver graft regeneration when50%liver graft preserved for 16 h.

Objective To explore the microsurgical techniques in establishing an orthotopic rat liver transplantation model of 20% small-for-size graft. Methods A rat liver transplantation model of 20% small-for-size liver graft was orthotopically performed. Forty male Lewis rats were used as 20 donors and 20 recipients. Donor liver was perfused with 4℃ UW solution via donor portal vein. Su-prahepatic inferior vena cava was anastomosed end-to-end with running suture. Infrahepatic inferior vena cava and portal vein were reconstructed by cuff technique. A sleeve anastomosis for hepatic artery was used. Continuity of the bile duct was established with an end-to-end intraluminal stent. Survival rate of the recipients was recorded and immunohistochemical analysis of hepatocyte replication con-firmed by bromodeoxyuridine (BrdU) uptake. Results Totally 20 liver transplantations of 20% par-tial liver graft were successfully performed. The successful rate of the operation was 100%. Survival rate of the recipients with 20% liver grafts was 93.8% (＞14 d). Histological examination showed normal liver structure with limited injury after transplantation. The number of positively stained nuclei was significantly increased at 72 h after transplantation. Conclusion The 20Z% small-for-size liver grafts initiate and complete the process of liver regeneration after transplantation. Skillful microsur-gery is the key to success of the transplantation model. The stable model is suitable for basic research in partial liver transplantation.

Objective To sum up the clinical experience of liver retransplantation (ReTx).Methods All recipients were male. The average age was 50 years old (43-55). The indications included primary nonfunction (PNF) (1 case), acute rejection (1 case), chronic rejection and biliary infection (1 cases) and ischemic type billiary lesion and biliary infection (2 cases). The blood types of recipients and donors were identical. All donors were heart arrest. The immunosuppressive protocols included Zenapax and methylpredinisone (MP) and FK506. MMF was added if necessary.Results Three patients were cured. Two patients died at 8th and 10th day. One died of serious infection and failure of multiple organs and another died of heart failure. Complications included multiple organ infection (1 case) and biliary infection (1 case) and wound infection (1 case).Conclusion Liver retransplantation is an effective treatment for graft failure after liver transplantation. Proper indication and optimum operation time, intensive perioperative supervision and proper treatment were very important for improved effect of liver retransplantation.

Objective To study the effect of valsartan eluting-stent on vascular neointimal formation and angiotensin Ⅱ type 2 receptor (AT2R) expression and to access its feasibility to prevent in-stent restenosis and the mechanism. Methods Both the valsartan eluting-stents and the carrier eluting-stents were made with multi-layers coated methods. Bare stents, carrier eluting-stents and valsartan eluting-stents were implanted into the rabbits' abdominal aortias respectively. Abdominal aorta angiography was performed before and right after the operation and at 3 months after stent inplantation. The mean diameter of aortas in different groups were measured by Quantitative coronary angiography software. All the rabbits were killed 3 months after the procedure and the cross section of the stented vessel were analysed for neointimal formation. The luminal area, neointimal area, inner elastic membrane luminal area and the maximal inner-membrane thickness were compared between the 3 groups. The expressions of AT2R mRNA and the protein were determined by RT-PCR and histomorphometry. Results There were no significant differences in the mean aortic diameters among the 3 groups.The greatest luminal area and the minimal neointimal hyperplasia was found in the valsartan eluting-stents group compared with the other two groups. The mean luminal areas of the bare stents, carrier eluting stents and the valsartan eluting-stents were 4 345 548?1 258 22 ?m2, 4 302 061?167 952 ?m2 and 5 016 269?207 934 ?m2; the mean neointimal areas were 1 119 635?163 503 ?m2, 1 135 636?136 555 ?m2 and 441 577?74 099 ?m2 and the mean maximal inner-membrane thickness were 210?30 ?m, 192?21 ?m and 116?12 ?m respectively.The level of AT2R mRNA expression in the valsartan eluting-stents group was higher than that in the other two groups. The transcription of AT2R protein showed similar trend. Conclusion Valsartan eluting-stents enhanced AT2R mRNA and protein expression and inhibited neointimal hyperplasia which might play an important role in preventing restenosis.
