Comparison of intravascular ultrasound-guided with angiography-guided double kissing crush stenting for patients with complex coronary bifurcation lesions: Rationale and design of a prospective, randomized, and multicenter DKCRUSH VIII trial.

Background: Double kissing (DK) crush approach for patients with coronary bifurcation lesions, particularly localized at distal left main or lesions with increased complexity, is associated with significant reduction in clinical events when compared with provisional stenting. Recently, randomized clinical trial has demonstrated the net clinical benefits by intravascular ultrasound (IVUS)-guided implantation of drug-eluting stent in all-comers. However, the improvement in clinical outcome after DK crush treatment guided by IVUS over angiography guidance for patients with complex bifurcation lesions have never been studied in a randomized fashion.

Multislice Computed Tomographic Manifestation of Transient Hepatic Attenuation Difference in the Left Lobe of the Liver: A Retrospective Study.

Introduction: Transient hepatic attenuation differences (THAD) are areas of high parenchymal enhancement observed during the hepatic arterial phase on computed tomography (CT). THAD in the left lobe of the liver can lead to surgical complications.

Methods: A retrospective study was conducted on patients who underwent multislice computed tomography (MSCT) examination of the upper abdomen to understand the morphology, distribution, and causes of THAD and their correlation with hepatic artery variation.

Chinese expert consensus on the prevention of abdominal pelvic adhesions after gynecological tumor surgeries.

Adhesion is a postoperative complication that has plagued gynecologists for many years, as 60-90% of gynecological patients develop adhesions after abdominopelvic surgeries. Abdominopelvic adhesions could lead to chronic pelvic pain, infertility, intestinal obstruction, and complicated reoperations. Adhesions might also increase the risk of postoperative chemoradiotherapy failure and endanger patients' lives, especially after surgeries for gynecological malignant tumors.

Standardized fluorescence in situ hybridization testing based on an appropriate panel of probes more effectively identifies common cytogenetic abnormalities in myelodysplastic syndromes than conventional cytogenetic analysis: a multicenter prospective study of 2302 patients in China.

In an attempt to establish the advantages of fluorescence in situ hybridization (FISH) studies over conventional cytogenetic (CC) analysis, a total of 2302 de novo MDS patients from 31 Chinese institutions were prospectively selected in the present study for both CC and standardized FISH analysis for +8, -7/7q-, -5/5q-, 20q- and-Y chromosomal abnormalities. CC analysis was successful in 94.0% of the patients; of these patients, 35.

Profiling of alternative polyadenylation sites in luminal B breast cancer using the SAPAS method.

Breast cancer (BC) is a leading cause of cancer-related mortality in females and is recognized as a molecularly heterogeneous disease. Previous studies have suggested that alternative messenger RNA (mRNA) processing, particularly alternative polyadenylation [poly(A)] (APA), can be a powerful molecular biomarker with prognostic potential. Therefore, in the present study, we profiled APA sites in the luminal B subtype of BC by sequencing APA sites (SAPAS) method, in order to assess the relation of these APA site-switching events to the recognized molecular subtypes of BC, and to discover novel candidate genes and pathways in BC.

Catheter-directed thrombolysis in the treatment of acute deep venous thrombosis: a meta-analysis.

We performed a meta-analysis for systematic evaluation of the status quo of catheter thrombolysis for the treatment of acute lower limb deep vein thrombosis in China. We searched the China Biomedical bibliographic database (CBM), China National Knowledge Infrastructure (CNKI), Weipu full-text electronic journals, Wanfang full-text database, and Medline (1990 through June 2011) for clinical randomized controlled trials of catheter-directed thrombolysis and superficial venous thrombolysis to compare their efficacies for the treatment of acute deep vein thrombosis. The results were analyzed by using the Cochrane-recommended RevMan 4.

Iliosacral resections of pelvic malignant tumors and reconstruction with nonvascular bilateral fibular autografts.

Background: Iliosacral resection of pelvic malignant tumors and subsequent reconstruction have tested the ingenuity of orthopedic oncologists because of the difficulty of oncological wide resection and the complex biomechanics of the sacroiliac joint render reconstruction challenging. This study compared the functional and surgical outcomes of a biological reconstruction technique with the lack of reconstruction following iliosacral resection.

Methods: Twenty-six consecutive cases with malignant iliac tumors involving the sacrum were retrospectively reviewed.

The relationship between platelet endothelial cell adhesion molecule-1 and paraquat-induced lung injury in rabbits.

Background: Platelet endothelial cell adhesion molecule-1 (PECAM-1), also known as CD31, is mainly distributed in vascular endothelial cells. Studies have shown that PECAM-1 is a very significant indicator of angiogenesis, and has been used as an indicator for vascular endothelial cells. The present study aimed to explore the relationship between the expression of PECAM-1 and the degree of acute lung injury (ALI) and fibrosis in paraquat (PQ) induced lung injury in rabbits.

Cancer-testis antigens expressed in osteosarcoma identified by gene microarray correlate with a poor patient prognosis.

Background: From 30% to 40% patients with osteosarcoma eventually experience medical failure; and few biomarkers of prognostic significance have been established. High-throughput methods like gene microarray analysis can help to identify molecular biomarkers that are useful for diagnosing osteosarcoma and targeting its treatment.

Methods: Oligonucleotide microarrays were used to compare expression profiles of osteosarcoma cell lines and osteoblasts.
