ABSTRACT
Objective: To study the phenotypes of T cell in patients with Hashimoto thyrioditis (HT) and to analyze its relationship with the impairment of follicles, so as to provide evidence for clinical diagnosis and treatment. Methods: Totally 136 HT specimens were obtained by fine needle aspiration biopsy (FNAB) and were divided morphologically(L, P, O type). The serum parameters (TPOAb, TGAb, TSH) were tested, and 20 cases with nontoxic goiter were taken as control. Immunohistochemical assay was performed with 60 specimens and FCM (Flow cytometry) was used to study 23 specimens. The T cell infiltration and the distribution of CD3+, CD4+, and CD8+ T cells were compared between all types of HT tissues. The correlationship between the atrophic degree of follicle with T lymphocytes infiltration and phenotype was analyzed. Results: It was found that L type (n=58) and P type (n=28) had more serious follicle atrophy than that of O type (n=20) (P
ABSTRACT
<p><b>BACKGROUND</b>The University of Wisconsin colloid based preserving solution (UW solution) is the most efficient preserving solution for multiorgan transplantation. Unfortunately, unavailability of delayed organ preserving solutions hindered further progression of cardinal organ transplantation in China. In this study, we validated an organ preserving Changzheng Organ Preserving Solution (CZ-1 solution) and compared it with UW solution.</p><p><b>METHODS</b>A series of studies were conducted on how and how long CZ-1 solution could preserve the kidneys, livers, hearts, lungs and pancreas of New Zealand rabbits and SD rats. Morphology of transplanted organs was studied by visible microscopy and electron microscopy; biochemical and physiological functions and the survival rate of the organs during prolonged cold storage were studied.</p><p><b>RESULTS</b>There was no significant difference between CZ-1 and UW solutions in preserving the kidneys, livers, hearts or lungs of rabbits; kidneys, livers, intestinal mucosa or pancreases of SD rats or five deceased donors' testicles. In some aspects, such as preserving rabbits' hearts, rats' intestinal mucosa and pancreases, the effect of CZ-1 solution was superior to UW solution. CZ-1 could safely preserve kidneys for 72 hours, livers for 24 hours, hearts for 18 hours and lungs for 8 hours for SD rats. Twelve kidneys preserved in cold CZ-1 solution for 22 - 31 hours were transplanted successfully and the mean renal function recovery time was (3.83 +/- 1.68) days.</p><p><b>CONCLUSIONS</b>CZ-1 solution is as effective as UW solution for organ preservation. The development of CZ-1 solution not only reduces costs and improves preservation of organs, but also promotes future development of organ transplantation in China.</p>

Objective：To confirm the effects of the macrophages and NO in the fibrosis formation of transplanted kidneys with chronic rejection. Methods：The quantitive immunohistochemistry was employed to observe the changes of relative quantitiy of macrophages, NO, collagen Ⅲ andⅣ， and to reveal the association between the increases of macrophages， NO， histopathologic damages, deposition of collagen Ⅲ and Ⅳ, finally, to infer the roles of the macrophages and NO in the fibrosis formation of transplanted kidneys with chronic rejection. Results: The macrophages accumulated and increased in the glomeruli, the tubules and the intersiticia tissue of kidneys, which was companied by the increased expression of collagen Ⅲ and Ⅳ during the early and middle stages. However, the macrophages and NO could not be detected, which was companied by the decreased deposition of collagen Ⅲ and Ⅳduring the advanced stage. There were significant differences between the 3 types(glomerulus disease type,blocking vessel type and intersticial sclerostic type) (P<0.05 or P<0.01). Conclusion：The increase of macrophages and the NO may closely interrelated with the fibrosis formation in transplanted kidneys with chronic rejection.
