Introduction: MicroRNAs (miRNAs) are noncoding RNAs that regulate multiple cellular processes during cancer progression. MiR-335 has recently been identified to be involved in tumorigenesis of several cancers such as ovarian cancer and gastric cancer. However, the regulation of miR-335 in esophageal squamous cell carcinoma (ESCC) has not been reported yet. Methods: Expression of miR-335 in tumor and their normal matched tissues was determined by quantitative real-time PCR in 67 ESCC patients and its association with overall survival of patients was analyzed by statistical analysis. Results: The expression level of miR-335 was reduced in malignant tissue samples in comparison to normal matched tissue (P < 0.05). It was also proved that miR-335 expression was associated with ESCC histological grade, lymph node metastasis, tumor stage and clinical stage (P < 0.05). In addition, the Kaplan-Meier survival curves revealed that low miR-335 expression was associated with poor prognosis in ESCC patients. Multivariate analysis showed that miR-335 expression was an independent prognostic marker of overall survival of ESCC patients. Conclusions: The study proves for the first time that miR-335 is down regulated in a majority of ESCC patients. Our results indicate that miR-335 expression is an independent prognostic factor for patients with esophageal cancer, which might be a potential valuable biomarker for ESCC. Source

Objectives: This study was designed to observe the efficacy and safety of renal denervation from the inside and outside of renal arteries. Methods: Fourteen beagles were randomly divided into a control group (n = 4) and treatment group (n = 10). One renal artery in every beagle of the treatment group was randomly assigned to an intimal group (10 renal arteries) which underwent percutaneous renal denervation from the inside, and another renal artery was assigned to an adventitial group (10 renal arteries) which underwent renal denervation from the outside by laparotomy. Results: Compared with the intimal group, the renal norepinephrine (NE) concentration in the adventitial group had significantly decreased (p = 0.003) at 3 months postsurgery. Renal artery HE staining showed that the perineurium from the adventitial group appeared thickened. Western blotting showed that renal tissue tyrosine hydroxylase (TH) protein expression in the adventitial group was significantly lower than that in the intimal group (p < 0.01) at 3 months postsurgery. There was a renal artery stenosis and a renal atrophy in the intimal group after 1 month of follow-up. Conclusion: The inhibitory effect on renal sympathetic nerve activity was more effective in the adventitial group than the intimal group, and renal denervation in the former group was safe. © 2015 S.

Purpose: To investigate the expression and significance of the expression of nucleostemin (NS) and proliferating cell nuclear antigen (PCNA) protein in non-small cell lung cancer (NSCLC). Methods: Immunohistochemistry (streptavidin-peroxidase method) was used to detect NS and PCNA expression in 53 NSCLC samples and 15 normal lung samples. Results: NS protein expression was detected in 54.7% (29/53) of the NSCLC samples and 0% (0/15) of the normal lung samples (p<0.01). Furthermore, the positive expression rate of PCNA was 6.67% (1/15) in normal lung samples and 71.7% (38/53) in NSCLC samples (p<0.05). Also, the NS protein expression rate was 65.2% (15123) in adenocarcinoma tissue samples, significantly higher than that in squamous tissues, where the NS expression rate was 46.7% (14/30) (p<0.05). In addition, the NS expression rate of 42.9% (15/35) in well or moderately differentiated tumor tissues was lower than the rate of 77.8% (14/18) in poorly differentiated tumor tissues (p<0.05). The grade of differentiation had no correlation with tumor-node-metastasis (TNM) stage and lymph node metastasis (p>0.05). Also, the positive expression rate of PCNA was significantly higher in NSCLC samples than in normal lung samples (p<0.05). In addition, a positive correlation was found between NS and PCNA expression in NSCLC (p<0.05). Conclusion: The highly valuable tumor molecular markers, NS and PCNA, had higher expression levels in NSCLC samples. Combined detection of NS and PCNA may be important for the early diagnosis of lung cancer and individualized therapy, having also an important role in predicting tumor prognosis. Source

Background: Surgical repair is an effective method to treat ventricular septal defect (VSD) complicating acute myocardial infarction (AMI). However, the mortality rate remains high. This study was designed to assess the immediate and mid-term results of transcatheter closure of postinfarct muscular VSDs. Methods: Data were retrospectively collected from 42 AMI patients who underwent attempted transcatheter VSD closure between 2008 and 2012 in seven heart centers of China. Results: Nine patients underwent emergent VSD closure in the acute phase (within two weeks from VSD) while the others underwent elective closure. The time between VSD occurrence and closure in emergency group and elective group was 7.7. ±. 2.3 days and 35. ±. 14.5 days, respectively (p<. 0.01). The percentage of procedure success in the emergency group and elective group was 77.8% (7/9) and 97% (32/33), respectively (p= 0.048). The hospital mortality was higher for emergent closure in comparison to elective closure (66.7% vs. 6.1%, p<. 0.01). During a median follow-up of 25 months (0-58 months), two patients died at 8 and 29 months, respectively, and no serious complications occurred in other patients. Conclusion: Interventional postinfarct VSD closure is a safe and effective approach that can be performed with a high procedural success rate, with favorable outcomes if it can be undertaken >14 days postinfarct. © 2014 Japanese College of Cardiology.

Background: Star GK valves were widely used in China, and we studied the clinical follow-up results of patients with Star GK valve implants for more than one year. Methods: Clinical data were collected from those patients who had Star GK valve implants for over one year. Patients were divided into three groups: (1) AVR group: received aortic valve replacement surgery. Based on the valve model this group was further sub-divided into two groups: 21A group, and 23A group; (2) MVR group: received mitral valve replacement surgery. Based on the valve model this group was further sub-divided into three groups: 25M group, 27M group, and 29M group; (3) DVR group: received combined replacement surgeries including AVR + MVR. According to postoperative follow-up time these patients were divided into two groups: 1-year group and 3-year group. Follow-up data were collected by telephone, outpatient visits, or correspondence. Clinical data were aggregated by professional data scientists to conduct independent analyses. Results: 959 patients were included in the study following Star GK valve implant. Follow-up after 1 year found that thrombosis occurred in 4 cases, hemorrhage in 15 cases, left heart failure in 13 cases, paravalvular leakage in 5 cases, and death due to cardiac causes in 2 cases. Conclusion: The long-term efficacy of Star GK valve implants was satisfactory with low incidence of valve-related complications, and following Star GK valve implant, valve and blood were highly compatible and blood component damage was minor. Very low incidence rate of thrombosis was observed following Star GK valve implant, however, attention should be paid to adjust the anticoagulation intensity. © 2016 Forum Multimedia Publishing, LLC.
