AIM: To analyze the difference of endonuclease domain containing 1 (ENDOD1) expression be-tween benign prostatic hyperplasia ( BPH ) tissues and prostate cancer ( PCa ) tissues and to investigate the effect of ENDOD1 on the biological function of human prostate cancer cells .METHODS: The BPH samples ( n=20 ) and PCa samples (n=21) were processed and analyzed according to the instruction of immunohistochemical (IHC) staining.The mRNA and protein levels of ENDOD 1 in the normal prostate epithelial cells and prostate cancer cells were evaluated by RT -qPCR and Western blot , respectively .The recombinant plasmids pCMV-N-Flag-ENDOD1 was constructed and was trans-fected into the human prostate cancer cells .The proliferation , apoptosis , migration and invasion abilities of the prostate cancer cells were evaluated by MTT assay , flow cytometry, Transwell migration and Matrigel invasion assays , respectively. RESULTS:The analysis of variance of the immunoreactivity score showed that PCa tissues with high Gleason score dis -played significantly lower ENDOD1expression than that with low Gleason score and BPH (P<0.05).The expression of ENDOD1 at mRNA and protein levels in PC3 cells and DU145 cells was significantly lower than that in the LNCap cells (P<0.05).The proliferation of DU145 transfected with ENDOD1 was inhibited.The flow cytometry indicated that ENDOD1 over-expression in the DU145 cells resulted in a notable increase in G0/G1 phase arrest (P<0.05), but the ap-optotic rates showed no statistical difference .The results of Transwell assay showed that migration and invasion abilities of the cells were also inhibited after transfection with over-expressing ENDOD1 plasmid (P<0.05).CONCLUSION: The expression of ENDOD1 significantly decreased in prostate cancer with high Gleaon score .Meanwhile, the ENDOD1 is spe-cifically down-regulated in androgen independent prostate cancer (AIPC) cell lines.Over-expression of ENDOD1 remark-ably inhibits the proliferation , migration and invasion abilities of AIPC .

To explore the relationship between blood level of big endothelin and contrast-induced acute kidney injury (CI-AKI) in patients with emergent percutaneous coronary intervention (PCI). Methods: A total of 1061 consecutive patients received emergent PCI in our hospital from 2013-01 to 2015-06 were enrolled. According to blood levels of big endothelin, the patients were divided into 2 groups: Normal big endothelin group, n=236 and Elevated big endothelin group, n=825. The baseline condition, procedural features, occurrence rate of CI-AKI and composite endpoint events at 6 and 12 months post-operation were studied which including nonfatal myocardial infarction, revascularization, stroke and all-cause death. The risk factors for CI-AKI occurrence were identified by Logistic analysis. Results: The overall occurrence rate of CI-AKI was 22.7% (241/1061). Compared with Normal big endothelin group, Elevated big endothelin group had the higher incidence of CI-AKI, increased composite endpoint events at 6 and 12 months post-operation with P=0.041, P=0.040 and P=0.021, respectively. With adjusted covariates, elevated blood level of big endothelin, no matter as a continuous variable or categorical variable had the enhanced risk of CI-AKI incidence in patients after emergent PCI. Conclusion: Elevated blood level of big endothelin may significantly increase the risk of CI-AKI in patients with emergent PCI.

OBJECTIVETo investigate the effect of electro-acupuncture-anesthesia device (EAAD) as an auxiliary localizing method for brachiplex nerve blocking.

METHODSOne hundred and twenty patients scheduled for operation in upper limbs were randomly divided into group A and group B, 60 in each group. Bupivacaine 25 ml (0.375% in concentration) was used to block intermuscular plexus brachialis in the operation for anesthesia and EAAD was used for adjunctive localizing in group A, while in group B paresthesia elicitation was used.

RESULTSIn group A, the blocking was complete in 56 cases and incomplete in 4, the anesthesia effect was superior to that in group B, complete in 46, incomplete in 9, and of inefficient in 5 (P < 0.01).

CONCLUSIONEAAD provides a localizing method for plexus brachialis blocking more precise than paresthesia elicitation.

Objective: To investigate the clinical value of Bayesian network in predicting survival of patients with advanced gallbladder cancer(GBC)who underwent curative intent surgery. Methods: The clinical data of patients with advanced GBC who underwent curative intent surgery in 9 institutions from January 2010 to December 2015 were analyzed retrospectively.A median survival time model based on a tree augmented naïve Bayes algorithm was established by Bayesia Lab software.The survival time, number of metastatic lymph nodes(NMLN), T stage, pathological grade, margin, jaundice, liver invasion, age, sex and tumor morphology were included in this model.Confusion matrix, the receiver operating characteristic curve and area under the curve were used to evaluate the accuracy of the model.A priori statistical analysis of these 10 variables and a posterior analysis(survival time as the target variable, the remaining factors as the attribute variables)was performed.The importance rankings of each variable was calculated with the polymorphic Birnbaum importance calculation based on the posterior analysis results.The survival probability forecast table was constructed based on the top 4 prognosis factors. The survival curve was drawn by the Kaplan-Meier method, and differences in survival curves were compared using the Log-rank test. Results: A total of 316 patients were enrolled, including 109 males and 207 females.The ratio of male to female was 1.0∶1.9, the age was (62.0±10.8)years.There was 298 cases(94.3%) R0 resection and 18 cases(5.7%) R1 resection.T staging: 287 cases(90.8%) T3 and 29 cases(9.2%) T4.The median survival time(MST) was 23.77 months, and the 1, 3, 5-year survival rates were 67.4%, 40.8%, 32.0%, respectively.For the Bayesian model, the number of correctly predicted cases was 121(≤23.77 months) and 115(>23.77 months) respectively, leading to a 74.86% accuracy of this model.The prior probability of survival time was 0.503 2(≤23.77 months) and 0.496 8(>23.77 months), the importance ranking showed that NMLN(0.366 6), margin(0.350 1), T stage(0.319 2) and pathological grade(0.258 9) were the top 4 prognosis factors influencing the postoperative MST.These four factors were taken as observation variables to get the probability of patients in different survival periods.Basing on these results, a survival prediction score system including NMLN, margin, T stage and pathological grade was designed, the median survival time(month) of 4-9 points were 66.8, 42.4, 26.0, 9.0, 7.5 and 2.3, respectively, there was a statistically significant difference in the different points(P<0.01). Conclusions The survival prediction model of GBC based on Bayesian network has high accuracy.NMLN, margin, T staging and pathological grade are the top 4 risk factors affecting the survival of patients with advanced GBC who underwent curative resection.The survival prediction score system based on these four factors could be used to predict the survival and to guide the decision making of patients with advanced GBC.

OBJECTIVETo explore the association between the ABO blood group and the risk of myocardial infarction in Chinese people.

METHODSWe retrospectively recruited 1 988 consecutive patients with acute myocardial infarction (AMI) and 1 856 non-coronary artery disease (non-CAD) subjects who hospitalized in our hospital between January 2013 and December 2013. The clinical features and ABO blood group were analyzed.

RESULTSBlood group distribution was A (27.1%, 539/1 988), B (34.4%, 684/1 988), AB (10.8%, 215/1 988), O (27.7%, 551/1 988) in patients with AMI and A (26.7%, 496/1 856), B(32.2%, 598/1 856), AB(10.8%, 200/1 856), O (30.4%, 564/1 856) in non-CAD group. The single factor analysis showed that blood group O tended to be more common in the non-CAD group than in AMI group (P = 0.06). After adjustment for common cardiovascular risk factors such as age, gender, hypertension, diabetes, smoking and serum cholesterol level, the A, B, and AB blood groups were associated with increased risk of AMI compared with O blood group, and the difference was significant with A blood group (OR = 1.229, 95% CI 1.019-1.482, P = 0.031) and B blood groups (OR = 1.214, 95% CI 1.017-1.449, P = 0.032). In addition, non-O blood group remained significantly associated with the increased risk of AMI than O blood group after logistic regression analysis (OR = 1.223, 95% CI 1.048-1.426, P = 0.01).

CONCLUSIONOur results suggest that non-O blood group is associated with the increased risk of AMI.

OBJECTIVEThe clinical features of patients with mediastinal and/or neck hematoma after transradial cardiac catheterization were reviewed and analyzed to help the clinicians to recognize this complication, and try their best to avoid the complication and treat the complication properly.

METHODSA total of 8 patients with mediastinal and/or neck hematoma after right transradial cardiac catheterization in Fuwai hospital from January 1, 2005 to the end of 2012 were included in this study. Among these 8 patients, 1 patient underwent coronary angiography, 7 patients underwent percutaneous coronary intervention and drug eluting stents were successfully implanted in 6 patients. The clinical data of these patients were analyzed retrospectively.

RESULTSSuper slide hydrophilic guild-wire was used in all patients. These patients felt chest pain, dyspnea and neck pain and neck or throat tightness after the procedure. CT scan was performed in all 8 patients and reviewed mediastinal hematoma, 4 patients complicated with neck hematoma, and suspicious laceration on the right subclavian artery or branch of innominate artery were found in 2 patients. Post procedure hemoglobin decrease was evidenced in all 8 patients. Anti-platelet therapy was discontinued until discharge in 2 patients, dual anti-platelet drugs were transiently discontinued or underwent dosage reduction in 4 patients, protamine was administered in 2 patients to neutralize heparin. Blood transfusion was not required, there was no stent thrombosis, and surgery was not indicated for all 8 patients. No complication was reported during follow up.

CONCLUSIONSMediastinal and/or neck hematoma is a rare complication post transradial catheterization approach. This complication is caused by super slide guild-wire or catheter's injury of small vessels near the aortic arch or subclavian artery, especially with rough manipulation. Neck and mediastinal CT scan should be performed as early as possible for patients with suspect hematoma and prognosis is usually fine with suitable therapy.
