Objective:To evaluate the influence of prophylactic intra-coronary injection nitroglycerin with diltiazem in patients of acute ST segment elevation myocardial infarction(STEMI) Methods:This study was conducted in 212 patients with acute STEMI who underwent primary percutaneous coronary inter- vention(PCI)in our center from January 2001 to December 2006.The patients were randomly assigned to receive intra-coronary nitroglycerin with dihiazem(n = 87)or none of them(125)before intervention.The clinical data,coronary angiography data after intervention,ST-segment resolution,area under the curve of CK-MB,ejection fraction(EF)and left ventricular end-diastolic di- mension several days alter operation and the major adverse cardiac events(MACE)were analyzed systemically. Results:Ten(11.5%)patients in study group and 28(22.4%)in control group had MACE(P = 0.042).The difference of re-hospitalization was also significant(19.5% vs 37.6%,P = 0.008).No/slow reflow occurred less in study group than in con- trol group,but the difference was not significant.Corrected TIMI frame count was lower(34.4?11.3 vs 38.9?17.2,P = 0.034) and myocardial blush grade was higher(2.65?0.6 vs 2.41?0.7,P =0.018)in study group.ST-segment resolution,area under the curve of CK-MB in 5 days after operation,EF and left ventricular end-diastolic dimension in study group were more significant than those in control group(P

Objective To study the methylation status of the promoter region of several tumor suppressor genes in p53-Bax mitochondrial apoptosis pathway and its role in cholangiocarcinoma. Methods The hypermethylation of the promoter region of tumor suppressors death-associated protein kinase (DAPK), p14, and target of methylation-associoted silencing-1 (TMS1/ASC) were detected by methylation-specific PCR. P53 gene status (exon 5-8 ) were examined by automated sequencing. The relationship between gene mutations and the biological behaviors of cholangiocarcinoma was analyzed. Results Methylation existed in at least one promoter region of tumor suppressor gene in the tumor tissues of 24 patients (66. 7% ). The frequencies of tumor suppressor gene methylation in cholangiocarcinoma were: p14 24%, DAPK 30. 6%, and TMS1/ASC 36. 1%. The frequencies of tumor suppressor gene methylation in the adjacent tissues were: TMS1/ASC 8.3% and DAPK 5.6%. DNA sequencing showed p53 gene mutation was found in 22 of 36 patients (61.1% ), and p53 gene mutation combined with the methylation of tumor suppressor was found in 14 (38.9%) patients, which was significantly correlated with pathologic biology, invasion, and differentiation ( P ＜ 0.05 ). The 1-year, 2-year, and 3-year survival rates were significantly higher in tumor-suppressing genes methylation group ( n = 4) (70%, 43 %, and 28%, respectively)than those in p53 gene mutation group (n = 14) (28%, 5%, and 0%, respectively) (χ2 =9. 060, P =0.03).Conclusions Promoter hypermethylation of p53-Bax mitochondrial apoptosis pathway is a common epigenetic event in cholangiocarcinoma. Although the methylations of TMS1/ASC and DAPK genes in the adjacent tissues are relatively low, they may be informative for the early detection of cholangiocarcinoma. P53 gene mutation combined with the methylation of tumor suppressor may be related with the pathologic biology of cholangiocarcinoma, making the latter trend to be with high malignancy and poor prognosis.

Objective To study the effectiveness and safety of methods of transurethral bipolar plasmakinetie prostatectomy for benign prostatic hyperplasia with large volume.Methods The transurethral bipolar plasmakinetic prostatectomy with Nesbit (Nesbit group,45 cases)and prying-up technique (pryhag-up group,60 cases)were performed in 105 patients of the prostatic volume of more than 60 g.The results could be obtained by comparing operative time,intraoperative and postoperative blood loss and the time of postoperative sustained washing of the bladder between the two groups.Results In Nesbit group,the efficiency of average cutting gland was (0.79±0.17)g/min,the average intraoperative blood loss was (3.87± 1.09)ml/g,the decrease in postoperative Hb within 24 hours was (6.84±3.96)g/L,the average time of postoperative continuous washing of the bladder was 72 hours,8 patients were given by blood transfusion.In prying-up group,the corresponding data were(1.16±0.20) g/min,(1.60±0.64)ml/g,(3.87±2.33 )g/L,36 hours respectively,none of patients was given by blood transfusion.There were statistically significant in two groups(P＜0.05).Conclusions The adoption of prying-up is more favorable compared with Nesbit method in the aspects such as less blood loss,shorter operating time,less lotion,more thorough resection of the gland,higher security.It is conducive to delivering lecture,and it enables the standard operational procedure available.

Objective To evaluate the diagnostic value of transrectal three-dimensinal ultrasonography for virgin polycystic ovarian syndrome(PCOS) patients.Methods Transrectal three-dimensional ultrasonography were performed on 45 virgin patients with PCOS,30 with polycystic ovary(PCO) and 25 controls.Ovarian follicle numbers(FN),ovarian volume(OV),ovarian stroma area(SA),total area(TA) and SA/TA ratio and correspondent biochemical parameters were measured.Results Transrectal ultrasonography was more reliable than abdominal ultrasonography in the detection of delicate structure of ovary in virgin patients.This method was noninvasive,convenient,distinct and sensitive.Patients with PCOS showed sinificantly higher SA and SA/TA compared to those of the PCO group and control group.Conclusions In the case of detection of PCOS in virgin patients,transrectal three-dimensional ultrasonography combined with transabdominal ultrasonography can improve the precision of the diagnosis of PCOS.The SA/TA ratio might be considered as the ultrasound diagnostic parameter in PCOS.

Objective Acute kidney injury (AKI) frequently occurs after catheter-based interventional procedures and increases mortality. How-ever, the implications of AKI before thoracic endovascular aneurysm repair (TEVAR) of type B acute aortic dissection (AAD) remain un-clear. This study evaluated the incidence, predictors, and in-hospital outcomes of AKI before TEVAR in patients with type B AAD. Meth-ods Between 2009 and 2013, 76 patients were retrospectively evaluated who received TEVAR for type B AAD within 36 h from symptom onset. The patients were classified into no-AKI vs. AKI groups, and the severity of AKI was further staged according to kidney disease:im-proving global outcomes criteria before TEVAR. Results The incidence of preoperative AKI was 36.8%. In-hospital complications was significantly higher in patients with preoperative AKI compared with no-AKI (50.0%vs. 4.2%, respectively;P<0.001), including acute renal failure (21.4%vs. 0, respectively;P<0.001), and they increased with severity of AKI (P<0.001). The maximum levels of body tem-perature and white blood cell count were significantly related to maximum serum creatinine level before TEVAR. Multivariate analysis showed that systolic blood pressure on admission (OR:1.023;95%CI:1.003–1.044;P=0.0238) and bilateral renal artery involvement (OR:19.076;95%CI:1.914–190.164;P=0.0120) were strong predictors of preoperative AKI. Conclusions Preoperative AKI frequently oc-curred in patients with type B AAD, and correlated with higher in-hospital complications and enhanced inflammatory reaction. Systolic blood pressure on admission and bilateral renal artery involvement were major risk factors for AKI before TEVAR.

Objective:To explore the correlation between glycemic control of type 2 diabetes mellitus (T2DM) patients and brachial-ankle pulse velocity (baPWV). Methods:A community-based cross-sec-tional study was conducted in Beijing, China. Every subject underwent physical examinations, glycated hemoglobin ( HbA1 c ) , blood lipid and baPWV measurements and completed a standardized question-naire. T2DM patients were divided into well controlled and poorly controlled groups according to HbA1c levels. The correlation between glycemic control of T2DM patients and baPWV was analyzed. Results:In this study, 1 341 subjects were recruited, including 733 T2DM patients and 608 non-diabetes sub-jects. Compared with non-diabetes subjects, abnormal baPWV ( baPWV≥1 700 cm/s) rate for T2DM patients was higher (40. 8% vs. 26. 8%, P<0. 001). With HbA1c<6. 5% or <7. 0% as the aim of glycemic control in T2DM patients, the abnormal baPWV rates for non-diabetes subjects, well controlled and poorly controlled T2DM patients were significantly different (non-diabetes vs. HbA1c<6. 5% T2DM vs. HbA1c≥6. 5% T2DM: 26. 8% vs. 32. 8% vs. 42. 6%, P <0. 001; non-diabetes vs. HbA1c <7. 0% T2DM vs. HbA1c≥7. 0% T2DM:26. 8% vs. 36. 1% vs. 43. 4%, P<0. 001). After being ad-justed for gender, age, smoking status, diabetes mellitus family history, T2DM duration, cardiovascular diseases ( CVD ) , waist hip ratio ( WHR ) , systolic blood pressure ( SBP ) , diastolic blood pressure ( DBP) , total triglycerides ( TG) , high density lipoprotein cholesterol ( HDL-C) , and low density lipo-protein cholesterol ( LDL-C ) , the Logistic regression models suggested that glycemic control status of T2DM patients was associated with abnormal baPWV. Compared with non-diabetes subjects, the ORs for abnormal baPWV in HbA1 c <6 . 5% T2 DM patients and HbA1 c≥6 . 5% T2 DM patients were 0 . 927 (95%CI 0. 560-1. 537) and 1. 826 (95%CI 1. 287-2. 591). Compared with non-diabetes subjects, the ORs for abnormal baPWV in HbA1c<7. 0% T2DM patients and HbA1c≥7. 0% T2DM patients were 1. 210 (95%CI 0. 808-1. 811) and 1. 898 (95%CI 1. 313-2. 745). Conclusion:The glycemic con-trol status of T2DM patients from communities is significantly associated with baPWV. Poor glycemic con-trol is a risk factor for abnormal baPWV. Keeping HbA1c under control might lower the risk of cardiovas-cular diseases in T2DM patients.

Objective: To compare the efifcacy of direct and pre-dilated atherectomy (RA) for treating the patients with calciifed coronary lesions. Methods: A total of 137 coronary artery disease (CAD) patients received RA treatment in our hospital from 2010-04 to 2014-09 were retrospectively studied. The ischemic related lesions were all deifned as calciifed coronary lesions. The patients were divided into 2 groups: Direct RA group,n=81 and Pre-dilated RA group, the patients received balloon dilatation followed by RA,n=56. The procedural features, complications, in-hospital and 1 year occurrence rates of major cardiaccerebral vascular events (MACCE) were compared between 2 groups. Results: Compared with Pre-dilated RA group, Direct RA group had the less pre-stent balloon application,P=0.000 and the higher maximum post-dilatationpressure,P=0.004; lower rate of in-operative complication (14.8% vs 32.1%),P=0.016; higher rate of acute lumen gain (128.52±75.77) % vs (77.12±27.01) %,P=0.004; lower MACCE occurrencerate(7.3% vs 23.6%) at 1 year period,P=0.006.Cox regression analysis presented that the following indexes were related to MACCE occurrence within 1 year of RA treatment: balloon dilatation before RA (HR=8.166, 95% CI 1.872-35.614,P=0.005), left main disease (HR=13.649, 95% CI 2.983-62.440,P=0.001), minimum post-operative lumen area (HR=0.583, 95% CI 0.378-0.879,P=0.010), post-dilatation (HR=0.066, 95% CI 0.013-0.332,P=0.001) and EF>40% (HR=0.019, 95% CI 0.002-0.158, P=0.000). Conclusion: Direct RA had the lower MACCE occurrence rate at 1 year period, this might be related to less operative complication and the optimal lumen gain.
