Objective To compare the efficacy and safety of Tacrolimus(FK506)and Neoral CsA in conjunction with MMF(2.0g/d)and steroid in preventing renal allograft rejection.Methods 98 cases of renal transplant recipients were randomly divided into two groups:FK506 group(n=40),receiving tacrollimus,MMF and prednison(Pred);CsA group(n=58),receiving CsA,MMFand Pred.Results The mean follow-up time in both two groups Was 12.5 months.Acute transplanted renal rejection occurred in 2 cases in FK506 group and 9 cases in CsA group respectively.The one-year person/kidney survival rate was 100%/100%in FK506 group and 100%/94.8%in CsA group respectively.The dosage of Pred in FK506 group was lower than in CsA group.12 cases in FK506 group had stopped using Pred.Hypergly cermia occurred in 7 cases in FK-506 group.Polytricosis,gingival hyperplasia and liver function disorder dominantly occurred in CsA group.Infection Was found in 9 cases of FK506 group and 11 cases of CsA group respectively.Conclusion FK506 combined with MMF could decrease the occurrence of acute trans planted renal rejection and the dosage of Pred.The good adjustment of the dose of FK506 iS helpful for re ducing the side effects and preventing rejection.

(0.05). The CsA dosage and C 2 concentrations were lower in group II than in group I.Conclusion Neoral C 2 monitoring are beneficial to clinical outcomes in elderly Chinese renal transplant recipients and C 2 (concentration) is lower in elderly recipients than in young ones.

Objective To evaluate the value of the StealthStation neuronavigation in the operation of intracranial lesions. Methods 22 patients with different intracranial lesions, including 14 cases of glioma, 2 cases of meningioma,4 cases of cavernous angioma,1 case of lymphoma and 1 case of metastatic cancer, were operated on with the aid of StealthStation neuronavigational system. The neuronavigational accuracy and surgical effect were analysed. Results All intracranial lesions were found accurately with StealthStation neuronavigational system, the predicted accuracy (PA) value was 2.53?0.73mm, accuracy sphere of intracranial lesions in the neuronavigational system was within 2mm in all patients. 13 cases out of 14 gliomas were totally removed under microscope, in 1 case removal was subtotal. In 2 patients, neurological symptoms became worse immediately after the operation but improved within 3 months after the operation. The other 12 patients recovered very well. In another 8 cases total removal under microscopy was successful, but one lymphoma patient showed exacerbation of neurological symptoms immediately after operation, but improved within 1 week after operation. The other 7 cases recovered very well. Conclusion The StealthStation neuronavigational system is reliable and accurate in neurosurgical operation, thus it is helpful to facilitate total resection of intracranial lesions with less operative complications.

Objective To investigate the effect and mechanism of STAT3 gene silencing on the growth of xenografts in human pancreatic cancer SW1990 cells in nude mice.Methods The expression vector inserted with shRNA targeting at STAT3 gene was constructed and was stably transfected into SW1990 cells (SW1990-RNAi group).SW1990 cells transfected with negative control shRNA expression vector (SW1990-Con group) and parent SW1990 (SW1990 group) were used as controls.STAT3,VEGF,MMP-2 protein expressions in these groups were determined by using Western blot.The subcutaneous xenografts models were established in nude mice,and the growth of xenografts was observed,CD34 expressions were determined by immunohistochemistry and MVD was measured.Results The expression of STAT3 protein was 84.69 ± 9.31,82.00 ± 7.76,7.93 ± 1.24,repectively,in SW1990 group,SW1990-Con group,SW1990-RNAi group,and the expression of VEGF protein was 82.94 ± 8.97,80.86 ± 10.28,39.04 ± 6.23,respectively,and the expression of MMP-2 protein was 40.88 ± 5.09,38.26 ± 5.71,12.54 ± 2.15,respectively.The expression in SW1990-RNAi group was significantly lower than those in other 2 groups (P ＜ 0.05),while the expression of all three proteins between SW1990-Con group and SW1990 group was not significantly different.The weight of the xenografts in SW1990 group,SW1990-Con group,SW1990-RNAi group was (2.2 ± 0.4),(2.2 ± 0.3),(0.5 ± 0.3) g,respectively ; the MVD of the xenografts was (20.35 ± 2.41),(18.79 ± 1.94),(9.62 ± 1.06) per high power field,respectively,and the number in SW1990-RNAi group was significantly lower than those in other 2 groups (P ＜ 0.05 or P ＜ 0.01),while the difference between SW1990-Con group and SW1990 group were not significant.Conclusions Inhibition of STAT3 gene expression can significantly slow the growth of SW1990 xenografts in nude mice,and the mechanism may be related with down-regulation of VEGF and MMP-2 expression and inhibition of the angiogenesis of pancreatic cancer.

Objective To investigate the change and clinical significance of thyroid CT value in patients with Graves disease and Hashimoto' s thyroiditis (HT).Methods One hundred and twelve Graves patients (GD group),54 HT patients (HT group) and 36 healthy people (NC group) were selected as our subjects.Computed tomography (CT) value of thyroid were measured.Results The CT value of the left thyroid gland was (70.53 ± 15.44) Hu in GD group,while (70.50 ± 16.01) Hu at the right side.In HT group,the CT value of the left thyroid gland was (53.77 ± 4.88) Hu,and (52.38 ± 6.67) Hu at the right side.The CT value of the left and right sides was (99.66 ±9.80) Hu and (100.77 ± 10.66) Hu in the NC group respectively.The CT value of GD and HT group were lower than that of the NC group (P ＜ 0.01),and the CT value of the HT group lower than that of the GD group more significant (P ＜ 0.01).Conclusion (1) The CT value of the GD group and the HT group are significantly lower than the NC group and the CT value of the HT group reduces more apparently than that of the GD group.(2) CT values can be used as an early,non-invasive diagnosis of GD and HT secondary indexes.

Objective To investigate the influence of immunosuppression strategy optimization on the outcomes of the renal transplant recipients in the last decades. Methods Data from 404 renal transplant recipients from Jan. 1st, 2001 to Dec. 31st, 2010 were analyzed retrospectively. The patients were divided into early transplant group (n = 260) and late transplant group (n= 144). The change of immunosuppression strategy included a low dose antithymoglobin (ATG) induction, a quick corticosteroid reduction and mycophenolate mofetil therapeutic monitoring with calcineurin inhibitor minimization. Recipients' gender,age, donor type, induction therapy, immunosuppression regime, occurrences of biopsy-proven acute rejection (BPAR), severe pulmonary infection and patient/allograft survival were compared between groups. A Cox regression model was used to investigate the factors that influenced the allograft survival. Results The follow-up rate was 98. 3 % in this study. The median follow-up period was 65 month (1-112 months). The proportion of ATG induction in late transplant group was significantly higher than in early transplant group (78. 5 % versus 31. 9 %, P<0. 01). The severe pulmonary infection rate was lower in late transplant group, while the BPAR rate was comparable between two groups. The allograft survival rate was significantly higher in late transplant group. Severe pulmonary infection was correlated with patient/allograft survival in Cox regression model. Conclusion The improvement of outcome in renal transplant recipients in our center is related to the optimization of immunosuppression strategy that reduces the severe pulmonary infection rate with no increase in BPAR.

Aim To assay the possible targets of adriamycin (ADM), screening ADM resistance related proteins.Methods The drug sensitivity of the cells was analyzed by IC50 assay;RT-PCR assay was used to detect the expression of genes in the cells;CMPK1 protein expression was tested by Western blot assay;the expression of CMPK1 in the cells was decreased by siRNA of CMPK1.Results Data from IC50 assay showed the sensitivity of cells transfected with CMPK1 was increased most(IC50 HEK293-CMPK /IC50 HEK293-Control=0.15, P<0.01), and the expression of CMPK1 protein in ADM resistant breast cells (MCF7/ADM) was lower than that in parent MCF7 cells (P<0.05).When the expression level of CMPK1 was decreased by CMPK1 siRNA, the sensitivity of MCF7 cells to ADM decreased (IC50 MCF7-siCMPK1/IC50MCF7-Control=3.6, P< 0.01), and the sensitivity of MCF7 cells to paclitaxel and gemcitabine also decreased.Conclusions CMPK1 was related to the multidrug resistance of cells, and the expression of CMPK1 was positively related to the sensitivity to drugs, which provides the possibility of CMPK1 as a target in the treatment of multidrug resistance.

Objective:To evaluate the differences of clinical parameters and putative periodontal patho-gens in sites of different probing depth ( PD) reduction after non-surgical periodontal treatment in patients with aggressive periodontitis ( AgP ) .Methods: Clinical examinations including plaque index , probing depth (PD), attachment level (AL) and bleeding index (BI), and full-mouth periapical photographs were collected from 20 patients with AgP .All the patients received non-surgical periodontal treatment , including oral hygiene instruction , supra-gingival scaling , subgingival scaling and root planing ( SRP ) and were followed up for 6 months post-therapy.Gingival crevicular fluids (GCF) were collected at 1 site in each quadrant before and at the end of 6 months post-therapy .Six kinds of putative periodontal patho-gens and 6 kinds of short chain fatty acids ( SCFAs ) were detected in the GCF samples .Results: The baseline clinical parameters of PD , AL and BI , the baseline concentration of succinic acid , acetic acid , propionic acid and butyric acid , and the prevalence of Treponema denticola were significantly higher in sites with PD reduction more than 2 mm sites compared with PD reduction no more than 2 mm sites [(7.7 ±1.2) mm vs.(5.1 ±1.8) mm, (6.3 ±1.9) mm vs.(4.5 ±2.2) mm, 3.8 ±0.4 vs.3.3 ± 0.8, 1.66 mmol/L vs.1.10 mmol/L, 31.67 mmol/L vs.17.78 mmol/L, 3.31 mmol/L vs.1.95 mmol/L, 84.6%vs.56.1%, P<0.05].However, there were no significant differences in the clinical param-eters, the 6 kinds of putative periodontal pathogen detection and SCFAs concentration between the 2 groups at the end of 6 months post-treatment.In sites with PD>5 mm at the end of 6 months post-thera-py , all were found with red complex bacteria infection .Conclusion:The baseline clinical parameters are important factors in predicting PD reduction after non-surgical periodontal treatment in patients with AgP . In sites with deep pockets after non-surgical periodontal treatment , the active control of red complex bac-teria is recommended .
