AIM: To identify the potential elements within the survivin promoter indispensable for the upregu-lation of survivin by Kaposi’ s sarcoma-associated herpesvirus encoded replication and transcription activator ( KSHV RTA).METHODS: A series of truncated survivin promoter luciferase constructs were generated.Reporter assay and chromatin immunoprecipitation were performed to detect the interaction between RTA and the important cis-acting elements. RESULTS: Deletion of the GC/Sp1 and p53 binding sites within the survivin promoter almost completely shut down the survivin promoter activity and the p53 cis-acting element synergistically contributes to survivin promoter activation by RTA. CONCLUSION: KSHV RTA interacts with the GC/Sp1 and p53 cis-acting elements and regulates the expression of cellu-lar survivin by specifically increasing the activity of survivin promoter.
2.Frequent epigenetic silencing of proapoptotic gene MAPK10 by methylation in B cell lymphoma
Journal of Leukemia & Lymphoma 2010;19(5):272-275
Objective To investigate epigenetic silencing of the proapoptotic gene MAPK10 by methylation in B-cell lymphoma. Methods We examined MAPK10 expression and methylation in seven cell lines derived from B-cell lymphoma by semi-quantitative RT-PCR and methylation-specific PCR (MSP), respectively. Methylation status was further examined in 24 diffuse large B-cell lymphoma (DLBCL), 15 follicular lymphoma (FL) and 12 reactive hyperplasia lymph nodes (LRH) both by MSP and bisulfite genomic sequencing (BGS). Results MAPK10 is silenced or downregulated in all seven B-cell lymphoma cell lines mostly due to promoter methylation. MAPK10 methylation was frequently detected in DLBCL (17 of 24, 71%) and FL (15 of 15, 100 %), but not in 12 LRH tissues. Conclusion MAPK10 is frequently inactivated by tumor-specific methylation, and thus, is a potential biomarker.

Objective To investigate the efficacy of monotherapy or combination of ACEI and ARB in treating diabetic nephropathy(DN). Methods 183 patients with DN were randomly allocated into three treatment groups: benazepril,losartan or the combination of these two drugs for 12 weeks.The changes of blood pressure, proteinuria, serum potassium and creatinine, creatinine clearance(Ccr)were observed before and after treatment. Results Both of benazepril and losartan reduced blood pressure and proteinuria efficiently.And their effects were similar.In contrast, the reduction in proteinuria was greater in the combination therapy than in treatments of either drug alone(P<0.05), but their reductions in blood pressure were achieved to the same level(P>0.05).There were not significant differences in serum levels of potassium, creatinine and Ccr before and after treatment(P>0.05). Conclusion A combination of ACEI and ARB in patients with DN produces a better anti-proteinuric effect than either of the monotherapies.This protection is not dependent on changes in blood pressure.

Objective To compare the accuracy of CE MRA and Gated 2D TOF MRA in evaluation of internal carotid artery stenosis. Methods 34 patients (male 27, female 7, age range 45-78 years) were evaluated with contrast enhanced three dimensional magnetic resonance angiography (CE MRA) and unenhanced ECG gated two dimensional time of flight MRA (Gated 2D TOF MRA). Digital subtraction angiography (DSA) was used as the “gold standard”. The MRA images were reprojected with maximum intensity projection (MIP) algorithm. Sensitivity, specificity, diagnositic accuracy,overestimation and underestimation were assessed. Results (1) DSA provided 68 diagnostic judgments: 23 were negatives and 45 were positives (mild stenosis 10, moderate stenosis 14, severe stenosis 17, occlusion 4). CE MRA was in agreement with angiography in 66 (97%), but overestimation resulted in 2 cases. Gated 2D TOF MRA was in agreement with angiography in 56 (82%), with 9 overestimation and 3 underestimation. (2) Taking negative and positive cases as judgement, CE MRA showed higher sensitivity, specificity, and diagnostic accuracy than Gated 2D TOF MRA (100% versus 95 6%, 100% versus 78.3%, 100% versus 89.4%, respectively). (3) Taking 70% stenosis as judgement, CE MRA also showed higher sensitivity, specificity, and diagnostic accuracy than Gated 2D TOF MRA (100% versus 95 2%, 97.8% versus 93.6%, 98.5% versus 94.1%, respectively). Gated 2D TOF MRA vs DSA, CE MRA vs DSA and Gated 2D TOF MRA vs CE MRA all had no significant difference (? 2=3.000 with P =0.083, ? 2=2.000 with P =0.157, and ? 2=1.600 with P =0.206 respectively) Conclusion Compared with Gated 2D TOF MRA,CE MRA is more accurate in evaluation of carotid artery stenosis.

Objective To evaluate the modification of C_(60) on the radiation effects of ~(60)Co-γ irradiation on zebrafish.Methods The adult and embryonic zebrafish were used as model organisms to examine the potential of C_(60) to elicit oxidative stress responses on the surviving rate,hatching rate and malformation occurrence,both upon exposure to light or in the dark.Reactive oxygen species (ROS) production and DNA damage were examined as the possible underlying mechanism.Results 500 × 10~(-9) nano-C_(60) waterborne exposure could enhance the γ-irradiation effects by decreasing adult fish survival upon light exposure,which resulted in ROS and DNA damage increasing.The hatching rates were also inhibited with higher malformation,though dark exposure did not make any enhancement,except that the 5000× 10~(-9) C_(60) would inhibit larvae hatching and induced more malformation.Conclusions Waterborne nano-C_(60) exposure may enhance the radiation effects on zebrafish,ROS production and DNA damage increasing may be the underlying mechanism.

Objective To analyze the complications, treatments and prognosis of simultaneous pancreas-kidney transplantation. Methods Forty cases of simultaneous pancreas-kidney transplantation performed between Dec. 1999 and Jan. 2010 in our center were retrospectively analyzed. Results Regarding surgical complications, 4 cases had severe hematuria after operation,which needed clinical intervention, including 1 patient receiving catheterization in duodenum to stop bleeding. Two patients were treated with continuous bladder irrigation, and the remaining one received surgical haemostasis because of donor's duodenum and bladder anastomotic artery hemorrhage.Abdominal hemorrhage occurred in 4 patients, including pancreatic hemorrhage in 3 cases and duodenal muscularis hemorrhage in one case. All of them received surgical treatment for hemostasis.Abdominal infection occurred in 8 cases: one died of multiple organ failure, 2 cases were cured after drainage of abscess, 2 cases underwent surgical removal of abscess, and 3 cases were cured after antibiotic therapy. In one case of postoperative anastomotic leakage, pancreas was resected. Four cases of postoperative ileus were cured by continuous clysis with traditional Chinese medicine. Seven cases had pulmonary bacterial infections, including one cases associated with fungal infection. They were cured by the anti-infective treatment. Other complication included poor healing in 5 cases and urinary infection in 2 cases. After combined simultaneous pancreas-kidney transplantation, 10 patients received reoperation because of surgical complications (14 operations). The re-operation rate was 25 %, including 2 patients (4 operations) for hematuria, 4 patients for abdominal hemorrhage, 2 patients (3 operations) for abdominal infection, 1 patient for pancreatic venous thrombosis, 1 patient for anastomotic leakage, and 1 patient for pancreatic fistula. Conclusion Although simultaneous pancreas-kidney transplantation provides a successful and effective treatment for diabetics with endstage renal disease, surgical complication is still affecting the pancreas and kidney grafts after transplantation.

Objectives To observe the changes of magnetic resonance imaging(MRI) during the course of treatment in hepatolen-ticular degeneration (HLD) and to evaluate its related factors.Methods Sixty - three patients with HLD received routine SE sequence MRI of brain and liver.Twenty - two patients with abnormal MRI in 42 patients and each of them had 2-4 times of serial MRI ex-aminations at interval of 1.0- 1.5 year.Results Ten patients had lesion in both brain and liver in 22 patients. Nine patients only in brain, 3 patients in liver.The major lesions disappear or decrease after rational treatments. There were only slight or no changes of MRI abnormalities in patients receiving treatments or age of patients was over 15 year old. Abnormal MRI findings shown again after stopped treatments over 2 months. In such cases, the clinical and MRI improvements were slow.The rate of clinical and MRI improvement in patients with adequate treatment were markedly higher than patients with inadequate treatment.Conclusions Liver and brain lesion will show in MRI disappear after adequate treatment;There are only slight or no change or showing again in MRI abnormalities in pa-tients with inadequate treatments compared with poor clinical improvement. MRI is beneficial to understanding therapeutic effect and prognosis of HLD.
