Serum concentrations of interleukin-6 (IL-6), soluble IL-6 receptor (sIL-6R) were determined in patients with Graves′ ophthalmopathy (GO), Graves′disease without GO (NGO) and controls. Patients with GO treated by corciosteroids were assessed by the clinical activity score (CAS). The results suggested that serum levels of both IL-6, sIL-6R and CAS could reflect the activity of GO and predict the outcome of corcicosteroid therapy.

Malignant lymphoma of the maxillary sinus is very rare. A case of diffuse large B-cell lymphoma (DLBCL) of the left maxillary sinus is presented here. A 59-year-old man came to our hospital complaining of swelling under the left lower eyelid without any other symptoms. Imaging examination including CT and MRI detected a tumor in the left maxillary sinus. The tumor was invasive into left orbit. The biopsy revealed a diffuse large B-cell lymphoma. The tumor cells were positive to CD20, CD79a, CD45. In conclusion, a very rare case of DLBCL of the maxillary sinus was reported.

Objective To investigate the effects of erythropoietin(EPO)on the function of glomerular endothelial cells in rats with chronic renal failure(CRF). Methods The CRF model was established by a two stage 5/6 nephrectomy procedure in rats.Experimental rats were randomly divided into four groups:sham operation group (control group),CRF group,CRF rats treated with 30 U/kg EPO(low-dosage group)and with 50 U/kg EPO (high-dosage group).CRF rats received EPO by hypodermic injection for 6 weeks and then were sacrificed.Serum creatinine(Scr),blood urea nitrogen fBUN),urine protein,haematoglobin (Hb) and blood pressure were measured.The renal morphologie changes were evaluated on periodic acid-schiff (PAS) stained sections.The CD34 and CD31 expressions in glomerulus were detected by immunohistochemistry method.The mRNA of endothelin 1(ET-1),endothelial nitric oxide synthase (eNOS) and vascular endothelial growth factor (VEGF) were detected by RT-PCR. Results The expressions of CD34 and CD31 protein in glomerulus,and the expressions of eNOS and VEGF roRNA in renal tissue were higher in EPO treatment group than those in CRF model group(all P<0,05).The expression of ET-1 mRNA in renal tissue was lower in EPO treatment group than that in CRF model group.In addition,the Scr,BUN,urine protein and blood pressure in EPO treatment group were significantly lower than those in CRF model group (all P<0.05).Haematoglobin in EPO treatment group was higher than that in CRF model group (P<0.05).Reanl pathological injury wss improved by EPO treatment in dose-dependent manner. Conclusion EPO can ameliorate renal pathological injury and renal function in rats with chronic renal failure,maybe through promoting the renovation of glomerular capillary endothelium and improving the function of glomerular endothelial cells.

Objective To investigate the clinical value of 99Tcm-MIBI SPECT-CT image fusion technology for diagnosing breast tumor and detecting axiiiary lymph node metastasis. Methods 99Tcm-MiBI breast and axillary lymph node planar and SPECT-CT imaging in 80 female breast tumor patients were done. All patients had pathological examination results after surgery as control. Results SPECT-CT fusion images sensitivity for breast cancer diagnosis, specificity and accuracy rates were 88.2 % (45/51), 93.1% (26/29) and 90 % (71/80). Planar imaging sensitivity, specificity and accuracy rate were 82.4 % (42/51), 79.3 %(23/29) and 81.3 %(65/80). SPECT-CT fusion images were higher than planar imaging (P <0.05). SPECT-CT fusion images sensitivity, specificity and accuracy for detecting axillary lymph node metastasis were 81.8 %(18/22), 89.7 % (26/29) and 86.3 % (44/51). Planar imaging sensitivity, specificity and accuracy were 77.2 % (17/22), 86.2 % (25/29) and 82.4 %(42/51). There was no significant difference between them (P0.05). Conclusion SPECT-CT image fusion technology in the diagnosis of breast cancer is better than planar imaging. SPECT-CT image fusion in detecting axillary lymph node metastasis of breast cancer is similar to planar imaging.

Objective To investigate the effects of erythropoietin (EPO) on the number and function of peripheral blood endothelial progenitor cells (EPCs) from rats with chronic renal failure (CRF). Methods The model of chronic renal failure was established by a two-stage 5/6nephrectomy procedure in rats. Experimental rats were randomly divided into four groups (n =7,respectively): sham operation group, CRF group, CRF rats treated with 30 U/kg EPO (low-dosage group) and with 50 U/kg EPO (high-dosage group). CRF rats were given EPO by hypodermic injection for 6 weeks, then EPCs were isolated by density gradient centrifugation from peripheral blood mononuclear cells. The ability of cell proliferation, adhesion and vasculogenesis in vitro was further observed. Results Compared to sham operation group, the ability of cell proliferation,adhesion and vasculogenesis in vitro in CRF rats was remarkably decreased (P＜0.05, respectively).Such ability was promoted significantly in dose-dependent manner by EPO treatment (P＜0.05,respectively). Conclusion EPO can improve the number and ability of endothelial progenitor cells from rats with chronic renal failure.

OBJECTIVE: To investigate the effects of atorvastin on function of glomerular endothelia cells in rats with chronic renal failure (CRF). METHODS: Twenty-eight male SD rats were randomly divided into 4 groups: sham operation group (control group), CRF group (model group), 8 mg · kg-1 · d-1 atorvastin treatment group (low-dosage group) and 16 mg · kg-1 · d-1 atorvastin treatment group (high-dosage group). The model of chronic renal failure was established by a two stage 5/6 nephrectomy procedure. The atorvastin treatment groups were given atorvastin by intragastric administration, and the other 2 groups were given sodium chloride. Serum creatinine (Scr), blood urea nitrogen (BUN), urine protein, total cholesterol (TCHO), triglycerides (TG), low density liporotein (LDL), AST, ALT and creatine kinase (CK) were measured after 8 weeks. The renal morphologic changes were e-valuated on periodic acid-schiff (PAS) stained sections. The CD34 and CD31 expressions in glomerulus were detected by immunohisto-chemistry method. The mRNA of ET1, eNOS and VEGF were detected by RT-PCR. RESULTS: The Scr, BUN and urine protein levels in atorvastin treatment groups were significantly lower than those in CRF model group (P < 0.05). Reanl pathological injuries were improved by atorvastin treatment in dose-dependent manner. There were no significant differences in TCHO, TG, LDL, AST, ALT and CK levels among the 4 groups. The expressions of CD34 and CD31 protein in glomerulus, and the expressions of eNOS and VEGF mRNA in renal tissue were higher in atorvastin treatment groups than those in CRF model group. The expression of ET-1 mRNA in renal tissue were lower in atorvastin treatment groups than those in CRF model group. CONCLUSION: It might be through promoting renovation of glomerulus capillary endothelium and improving function of glomerular endothelial cells that atorvastin ameliorates renal pathological injury and renal function in rats with chronic renal failure.

Objective To investigate the effects of erythropoietin (EPO) on complement 3a (C3a)-induced renal tubular epithelial to mesenchymal transition. Methods The HK-2 cells were divided into 6 groups namely control group,EPO group,TGF-β group,TGF-β+EPO group,C3a group and EPO+C3a group.The mRNA and protein expressions of α-SMA,E-cadherin and C3 were investigated by RT-PCR,Western blot and immunofluorescence respectively. Results Compared with control group and EPO group,the mRNA and protein expressions of α-SMA in HK-2 cells were up-regulated after the intervention of C3a or TGF-β (all P＜0.05).On the contrast,the mRNA and protein expressions of E-cadherin were down-regulated(P＜0.05),the mRNA and protein expressions of C3 were enhanced (all P＜0.05).However,all those above effects of C3a or TGF-β were inhibited after the intervention of EPO (all P＜0.05). Conclusion EPO is capable of suppressing the epithelial to mesenchymal transition induced by C3a.

OBJECTIVE: To optimize the MR imaging protocol for coronary arterial wall depiction in vitro and characterize the coronary atherosclerotic plaques. MATERIALS AND METHODS: MRI examination was prospectively performed in ten porcine hearts in order to optimize the MR imaging protocol. Various surface coils were used for coronary arterial wall imaging with the same parameters. Then, the image parameters were further optimized for high-resolution coronary wall imaging. The signal-noise ratio (SNR) and contrast-noise ratio (CNR) of images were measured. Finally, 8 human cadaver hearts with coronary atherosclerotic plaques were prospectively performed with MRI examination using optimized protocol in order to characterize the coronary atherosclerotic plaques. RESULTS: The SNR and CNR of MR image with temporomandibular coil were the highest of various surface coils. High-resolution and high SNR and CNR for ex vivo coronary artery wall depiction can be achieved using temporomandibular coil with 512 x 512 in matrix. Compared with histopathology, the sensitivity and specificity of MRI for identifying advanced plaques were: type IV-V (lipid, necrosis, fibrosis), 94% and 95%; type VI (hemorrhage), 100% and 98%; type VII (calcification), 91% and 100%; and type VIII (fibrosis without lipid core), 100% and 98%, respectively. CONCLUSION: Temporomandibular coil appears to be dramatically superior to eight-channel head coil and knee coil for ex vivo coronary artery wall imaging, providing higher spatial resolution and improved the SNR. Ex vivo high-resolution MRI has capability to distinguish human coronary atherosclerotic plaque compositions and accurately classify advanced plaques.
