OBJECTIVETo explore the values of adrenocorticotropic hormone receptor (ACTH-R) determination and ultrastructural observation of tumor cells in the subtyping of adrenocortical neoplasms (ANs).

METHODSThe expression of ACTH-R in 87 AN tissues were determined with Polymer immunohistochemical staining, with 10 normal adrenal tissues as the controls. The ultrastructure of the tumor cells was observed using electron microscopy.

RESULTSThe positive expression rate of ACTH-R was (80.1 +/- 8.2)%, (53.2 +/- 10.3)%, (63.2 +/- 10.1)%, (83.3 +/- 6.5)%, and (70.1 +/- 7.3)% in the sub-CPA group, CPA group, APA group, NFA group, and NC group, respectively. ACTH-R expression was significantly higher in NFA and sub-CPA groups than in NC group (P = 0.001, P = 0.000), APA group (P = 0.000, P = 0.000), and CPA group (P = 0.000, P = 0.000), and was also significantly different between NC group and APA group (P = 0.039) and between APA group and CPA group (P = 0.037). However, no significant difference was found between NFA group and sub-CPA group (P = 0.325). As shown by the electron microscopy, ANs had some partially similar microscopic features, while different AN subtypes showed differences in the type and amount of secretory granules.

CONCLUSIONACTH-R determination and ultrastructural observation of tumor cells may be helpful for subtyping ANs.

OBJECTIVETo detect the expressions of receptor tyrosine kinases (RTKs) mRNA and protein and to explore potentially promising tumor markers and conceivable drug target in bladder cancer.

METHODSThe expressions of RTKs mRNA and protein in tissue from invasive urothelial carcinoma of the bladder were examined by real-time quantitative PCR array and cytokine antibody array, with normal bladder tissue as control. The Results were analyzed using bioinformatic approaches.

RESULTSThe expressions of TGFA, STAB1, SERPINE1, ANGPT2, SPINK5, ANGPTL1, PROK1, MDK, CXCL9, GRN, RUNX1, VEGFA, and TGFB1 were obviously upregulated in bladder cancer tissue, while those of EDIL3, PTN, CCL2, PDGFD, FGF13, KITLG, FGF2, SERPINF1, and TNF were downregulated. ALK, Btk, EphB2, ErbB4, PDGFR-α, ROS, Tie-2, Tyk2, and VEGFR3 were over-expressed in bladder cancer, while FRK, Fyn, IGF-IR, Insulin R, Itk, JAK1, JAK3, and LCK were low-expressed.

CONCLUSIONVascular endothelial growth factor/platelet-derived growth factor-targeted therapies may play an active role in treating carcinoma of bladder.

Objective To analysis long-term effects and safety of arsenic trioxide (ATO)-based induction and maintenance therapy in newly diagnosed acute promyelocytic leukemia (APL). Methods Retrospective analysis induction remission and post-remission treatment of 62 newly diagnosed APL patients was performed. These cases were followed up for 5 and 7 years. Results The complete remission (CR) rate was similar in ATO/all-trans retinoic acid (ATRA) induction group and ATRA/chemotherapy induction group.However, the former group has the shorter time to CR. The negative rate of PML-RARα fusion gene after induction without ATO was less than that of ATO group (86.2 % vs 56.3 %, P ＜0.05). After CR, the 5-year overall survival (OS) between ATO-base rotation maintenance group and chemotherapy-base rotation maintenance group showed that the former was (94.4±5.4) %, the latter is (45.5±10.2) %; 7-year OS was (52.5±23.7) % and (27.3±9.3) %; 5-year disease free survivals (DFS) was (94.7±5,5) % and (41.3±10.1) %; 7-year DFS was (52.6±23.7) % and (27.5±9.4) %. There was significant different in 5-year or 7-year OS and DFS between two groups (P ＜0.05). The relapse rates of the two groups in post-remission treatment were 14.7 % and 37.0 % (P ＜0.05). Conclusion ATO combined ATRA induction therapy increased the negative rate of PML-RARα fusion gene. ATO-base rotation maintenance improved long-term outcome and decreased the rate of relapse. Furthermore, ATO appeared to be generally safe and well tolerated.

Objective Cancer radio-therapy may induce bone damage of the patients.collagen type I gene expressions in osteoblast after radiation indicates the influence of radiation on the function of early and late osteoblast.Methods Bone marrow stromal cells were differentiated into osteoblasts in vitro.and the characteristics was indentified.The collagen type I expressions in early and late stage osteoblasts exposed to 1～4Gy radiation were examined by RT-PCR.Results Compared to control group,collagen type I gene expressions increased in early osteoblast after 1～3 Gy radiation (P＜0.05),while the gene expressions in late osteoblast that cultured 10 days decreased.Collagen type I gene expression in late stage ostoblast after 4 Gy irradiation was greatly higher than that in early stage osteoblast (P＜0.01).Conclusion After 1～3 Gy irradiation,the collagen type I expression in early osteoblast was enhanced,indicating the increased ability of bone formation.The exposure to 1～3 Gy decreased collagen type I expression in late osteoblast and weakened the ability of bone formation.The result of high expression of collagen type I in late osteoblast after 4 Gy irradiation may be the manifestation of compensatory function.

OBJECTIVETo discuss the correlation between acute rejection episodes and expression of regulated upon activation normal T cell expressed and secreted (RANTES) and macrophage inflammatory protein-1 alpha (MIP-1 alpha) gene following kidney transplantation.

METHODSA total of 76 kidney biopsies (episode biopsy) were performed on both 57 patients with allograft dysfunction following transplantation and 19 patients without rejection, and the latter were served as controls. All acute rejections were confirmed by histological examination. The expressions of RANTES and MIP-1 alpha mRNA in all samples were assayed by reverse transcription polymerase chain reaction.

RESULTSThirty-eight (66.7%) of 57 cases with acute rejection had strong expression of RANTES, and 41 (72%) had expression of MIP-1 alpha. Only four (21%) of 19 controls had mild expression of RANTES, and 5 (26%) had expression of MIP-1 alpha, which evoked a statistical significance (P < 0.001) when compared with those with acute rejections.

CONCLUSIONSThe expressions of chemokines RANTES and MIP-1 alpha are important in the process of immune reaction in the rejection of transplanted kidney, which may imply a potential way for early diagnosis and treatment of acute rejection after further research.

OBJECTIVETo study the clinical significance of expression of hepatic growth factor (HGF) and its receptor c-Met in renal cell cancer (RCC).

METHODSTwenty-six patients with RCC and 10 benign renal tumor patients were examined. The expression of HGF and c-Met mRNA was detected using Northern blot. GAPDH was used as the internal control.

RESULTSTwenty-one out of 26 patients with RCC had positive gene expression of HGF and c-Met with the positive rate of 80.8%. According to the tumor TNM staging, the more advanced the cancer had a stronger expression of HGF and c-Met, the expression of c-Met was higher than that of HGF in the RCC. Whereas in the control group with benign tumor, the expression of c-Met was rather mild.

CONCLUSIONThe result suggests that HGF and its receptor c-Met may play an important role in the development and progression of renal cancer, which may also imply a potential clinical significance in diagnosing and assessing prognosis of RCC.
