Objective To investigate the clinical characteristics,manifestation and management of adrenal ganglioneuromas. Methods The data of 15 cases of ganglioneuromas diagnosed by pathology were reviewed retrospectively.Of the 15 cases,5 was male,aged 24 to 45 with an average of 29 years,and other 10 was female,aged 25 to 69 with an average of 31.Ten tumors were located in the right side,which was twice as many as that of the left side.There were 8 patients discovered by B ultrasonograpgy during health check-up,4 patients were detected because of paroxysmal abdominal pain. Three cases mainly presented with paroxysmally hypertension,and one of them had a high level of aldosterone ( 112 pmol/L). One of them had a high level of epinephrine (210 nmol) and nor-epinephrine (496 nmol). The B-ultrasound showed low-echo in all cases.Five cases showed calcification,the border was legible.The border lines of the tumors are not clear with vana cava in two cases. On unenhanced CT scanning,all cases showed low density areas.Eleven of the 15 cases underwent the enhanced CT,but 10 cases showed no enhanced areas on CT scanning.One case underwent MRI and showed low signals in T1 WI and inhomogeneous high signals in T2WI. Results Twelve cases underwent adrenal glands tumorectomy with abdominal NO.11 intercostals incision while other 3 underwent adrenal glands tumorectomy through posterior abdominal laparoscope.The tumors were completely removed in 14 cases,partly removed in 1 case.All patients recovered soon without complications such as bleeding or adrenal crisis.All cases were followed-up 13 to 74 months.The blood pressure of 3 cases with hypertension decreased to normal.The tumors recurred in 1 case,but no metastasis 55 months later. Conclusions It is difficult to differentiate adrenal medullary tumor from ganglioneuromas.The imaging data of iconography before surgery can give helpful information in the diagnosis of ganglioneuroma.Complete surgical excision is the only method for curing and the outcome is satisfactory.

Abstract? AIM: Through the establishment of penetrating keratoplasty model of rats, to detect the role and its mechanism of immature dendritic cells with IL-10 gene modified.? METHODS: Allogeneic penetrating corneal transplantation in rat model was performed. SD rats were randomly divided into positive control group, GFP-DC group, 8-DC and IL-10-GFP-DC group.At 3d before keratoplasty, the rats were given tail intravenous injection with the same amount of PBS, bone marrow 8-DC ( DC had cultured for 8d ) from donor Wistar rats, GFP-DC after 48h transfection and IL-10-GFP-DC.Rats were observed under slit-lamp for corneal graft cases every day, and recorded rejection index and corneal graft survival time.At 14d after keratoplasty, pathologic and immunohistochemical examinations were performed.?RESULTS:Compared with GFP-DC group and 8-DC group, corneal graft survival time of IL-10-GFP-DC group was significantly longer ( P<0.01 ); at 14d after keratoplasty, corneal opacity, edema, neovascularization and rejection index of IL-10 -GFP-DC group were significantly lower (P<0.01).Pathological examination showed that in the three experimental groups corneal inflammation was lighter than the positive control group without significant central graft neovascularization. Immunohistochemistry showed: compared to the positive control group, GFP-DC group and 8-DC group, CD4+, CD8+, CD25+, IL-2+, NK+and NF-κB+positive cells in IL-10-GFP-DC group were lower(P<0.01).? CONCLUSION: After donor -derived immature dendritic cells pretreated, corneal graft survival was significantly prolonged, successfully induced corneal transplantation tolerance. CD4+, CD8+, CD25+, IL-2+, NK+and NF-κB+positive cells are involved in corneal allograft rejection regulation, IL-10-GFP-DC may reduce CD4+, CD8+, CD25+, IL-2+, NK+and NF-κB+positive cell infiltration, inhibit corneal transplant rejection.

Objective To detect the effects of siRNA targeting CDX2 gene expression on of BCR-ABL, caspase and Bax expressions, and the mechanisms thereof. Methods According to the earlier experiments, siRNA specifically targeting CDX2 gene (CDX2-siRNA) and the negative control sequence (CDX2-siRNA-NC) were selected, and then were transfected into K562 cells by Roche X-tremeGENE HP DNA Transfection Reagent. The flow cytometry analysis was used to detect the effects of siRNA on cell apoptosis. The expressions of BCR-ABL, caspase-9, Bax mRNA and protein were tested by RT-PCR and Western blot assay. Results MTT and flow cytometry analysis showed that after the silence of CDX2 gene expression, the proliferation of K562 cells was prohibited and the apoptotic rate of K562 cells was distinctly increased compared with that of normal cell group, but the negative control group had no significant change. According to the RT-PCR and Western blot assay, in comparison with the normal cell group and the negative control group, the expression levels of BCR-ABL mRNA and protein were obviously decreased, and the difference was statistic significance. On the other hand, the expressions of caspase-9 and Bax mRNA and protein were significantly higher than those of other two groups (P<0.05). Conclusion CDX2-siRNA can promote apoptosis of K562 cells obviously, and the mechanism is related with the down-regulation of BCR-ABL and the up-regulation of caspase-9 and Bax.

Objective To observe the expression of connective tissue growth factor (CTGF) in pancreas, and discuss its significance. Methods The pancreatic fibrosis model was induced by high fat diets. The rats were sacrificed 16 weeks later, and the pancreatic tissue was harvested for routine pathologic examinations. Pancreatic collagen fibrosis I was determined by HE and Sirius red staining;α-SMA and CTGF expression were detected by immunohistochemistry. Results After pancreatic fibrosis, pancreatic lobules and acinar atrophy was observed, lobules gap was widened, interstitial fibrous tissue was significantly proliferated, the synthesis of pancreatic collagen fibrosis I was significantly increased when compared with normal pancreas ( 1500.2 + 255.8 vs. 57.4 ± 23.2, P < 0. 01 ), the expression of α-SMA was significantly increased when compared with normal pancreas( 1500.2 + 255.8 vs. 57.4 + 23.2, P < 0. 01 ), and the expression of CTGF was significantly increased when compared with normal pancreas (2950.5 ± 431.9 vs. 382.2 + 190.8, P <0.01 ), and there were abundant activated PSCs. Conclusions CTGF participated in the regulation of pancreatic fibrosis development; the function of CTGF was closely related to PSCs activation.

Previous studies have suggested that glutathione-S-transferase π (GST-π) over-expression in the brain tissue is associated with refractory epilepsy. However, whether the change in GST-π level in the peripheral blood is in line with that in brain tissue remains unknown. This study examined the correlation between GST-π in brain tissue and that in peripheral blood in rat models of pilocarpine-induced refractory epilepsy. The animals were divided into drug-resistant group and drug-responsive group according to the response to anti-epileptic drugs. GST-π expression in brain tissue was immunohistochemically determined, while the expression of GST-π in peripheral blood was analyzed by Western blotting. In the hippocampus and cortex, GST-π was mainly found in the cytoplasm and membrane of neurons, and the GST-π expression level was higher in drug-resistant group than in the drug-responsive group and saline control group (P<0.05). Moreover, there was no significant difference between responders and saline control animals (P>0.05). The change in expression of GST-π in peripheral blood showed the same pattern as that in brain tissues, suggesting GST-π might contribute to drug resistance in epilepsy. Importantly, the GST-π over-expression in peripheral blood could be used as a marker for resistance to anti-epileptic agents.

Objective To compare the expression level of interferon regulator factor 5 (IRF5) of the health controls and systemic lupus erythematosus (SLE) patients and analyze the relationship between IRF5 and SLE disease activity. Methods Peripheral blood monoeytes (PBMCs) from SLE patients and healthy donors were separated with Ficoll density gradient eentrifugation and total cellular RNA was isolated with Trizol from the PBMCs, the mRNA was reverse transcripted to cDNA. Real-time PCR was applied to determine the expression level of IRFS. The expression level of IRF5 between the two groups were compared. The correlations of expression level of IRF5 with SLE disease activity and other laboratory or clinical parameters of SLE patients were analyzed. Results The level of IRF5 was (2.1±2.2) in SLE patients and (1.5±1.2) in healthy controls, the difference was not statistically significant (P=0.161). And the levels of IRF5 in SLE patients were significantly correlated with their SLEDAI (r=0.616,P<0.01), but not correlated with other parameters such as bemoglobulin complements, immunoglobulin etc. Anti-dsDNA antibody positive patients had significantly higher expression of IRF5 compared to the anti-dsDNA-antibedy-negative patients. The IRF5 mRNA levels of SLE patients with fever or neuropsyehiatric symptoms were significantly higher than those of patients free of neuropsychiatrie involvement. Conclusion High expression level of 1RF5 may contribute to the pathogenesis of SLE in disease activity and antibody production.
