Background: XB130 is a recently discovered adaptor protein that is highly expressed in many malignant tumors, but few studies have investigated its role in hepatocellular carcinoma (HCC). Therefore, this study explored the relationship between this protein and liver cancer and investigated its molecular mechanism of action.
Methods: The expression of XB130 between HCC tissues and adjacent nontumor tissues was compared by real-time polymerase chain reaction, immunochemistry, and Western blotting.
Background: Decoy receptor 3 (DcR3) is a protein with anti-apoptotic effect that belongs to the tumor necrosis factor receptor superfamily. DcR3 is highly expressed in a variety of malignant tumors including cholangiocarcinoma and its expression was found to be related to the clinical stage, the invasion, and the metastasis of the tumor. This in vitro study aimed to investigate the effect of downregulated expression of DcR3 on cell viability, cell apoptosis, and cell cycle in cholangiocarcinoma cell line TFK-1.

The technique improves cosmetic outcomes, but a decrease in nipple sensitivity has been observed with NSM because of the incision into the nipple-areola complex (NAC). Endoscopic nipple-sparing mastectomy with skin lifting system (ENSMSLS) removes all breast tissue through the axillary incision used for the sentinel lymph node biopsy, to avoid incision around the NAC area.

Giant hiatal hernia (GHH) comprises 5% of hiatal hernia and is associated with significant complications. The traditional operative procedure, no matter transthoracic or transabdomen repair of giant hiatal hernia, is characteristic of more invasion and more complications. Although laparoscopic repair as a minimally invasive surgery is accepted, a part of patients can not tolerate pneumoperitoneum because of combination with cardiopulmonary diseases or severe posterior mediastinal and neck emphesema during operation.

The receptor is overexpressed in hepatocellular carcinoma (HCC), and it is associated with the growth and metastatic spread of tumors. DcR3 holds promises as a new target for the treatment of HCC, but little is known regarding the molecular mechanisms underlying the oncogenic properties of DcR3.

The choice of minimally invasive techniques and whether Heller myotomy with antireflux fundoplication should be employed after diverticulectomy became points of debate. The aim of this study was to describe how to perform laparoscopic transhiatal diverticulectomy (LTD) and oesophagomyotomy with the aid of intraoperative gastrointestinal (GI) endoscopy and how to investigate whether the oesophagomyotomy should be performed routinely after LTD.

Previous studies have demonstrated that intra-abdominal pressure (IAP) is increased in morbid obesity, and tracheal traction forces may influence pharyngeal airway collapsibility. This study aimed to investigate that whether IAP plays a role in the mechanism of upper airway (UA) collapsibility via IAP-related caudal tracheal traction.

With the application of minimally invasive techniques, surgical treatment to upper esophageal carcinoma tends to show more advantages and attract more patients. Up to now, most hospitals adopted the combined thoracoscopic and laparoscopic esophagectomy (CTLE) as the way of minimally invasive surgery for upper esophageal carcinoma.
View Article and Find Full Text PDFBackground: Transhiatal esophagectomy frequently is thought to achieve lower morbidity by sacrificing long-term survival at 5 years. With the introduction of the isobaric laparoscopy using abdominal wall lifting, the authors explore gasless laparoscopically assisted transhiatal surgical treatment of upper thoracic or cervical esophageal carcinoma after neoadjuvant chemotherapy. They wish it not only lower morbidity but also similarity to transthoracic esophagectomy, with extended en bloc lymphadenectomy in aspects of median overall, disease-free, and quality-adjusted survival.

Methods: A total of 145 in-patients with CHF in NYHA class II, III or IV despite optimized therapy were prospectively included in the study, grouped according to NYHA class and compared with 55 healthy control subjects.

Decoy receptor 3 (DcR3) is considered to have anti‑apoptotic and pro-metastatic functions, suggesting it might be a therapeutic target. We examined the role and mechanisms of DcR3 on growth and the metastatic ability of SW480 colon cancer cells to provide therapeutic information for targeting DcR3 by RNA interference (RNAi) technology. Growth and the metastatic ability were inhibited, apoptosis was induced and cell cycle profile was changed after decreasing DcR3 expression, with lower levels of vascular endothelial growth factors (VEGFs) and matrix metalloproteinases (MMPs) expression.

This study aimed to evaluate the technical feasibility, anatomical and functional outcomes of one-stage laparoscopic and gasless laparoscopic vaginoplasty with sigmoid colon for the patients of vaginal agenesis (Mayer-Rokitansky-Kuster-Hauser syndrome).
Methods: We did a retrospective review of a total of 150 women with Mayer-Rokitansky-Kuster-Hauser syndrome treated at Beijing Anzhen Hospital, Capital Medical University from March 2006 to August 2010.
Background: This study was to investigate the effects of multiple genetic polymorphisms and conventional risk factors in the prognosis of coronary artery disease (CAD).
Methods: One hundred and fifty five patients with CAD were prospectively recruited, they were subgrouped as single vessel disease (SVD) and multiple vessel disease (MVD). All patients were detected I/D polymorphism of angiotensin-converting enzyme (ACE) gene, 4G/5G polymorphism of plasminogen activator inhibitor-1 (PAI-1) gene, and G894→T mutation of endothelial nitric oxide synthase (eNOS) gene.

Objective: To study clinical effect of vaginoplasty with sigmoid colon by laparoscopic surgery.
Method: Clinical data of 45 cases with laparoscopic vaginoplasty using a vascularized pedicled sigmoid colon flap were reviewed, including 41 cases with congenital absence of vagina and 4 cases with male pseudohermaphroditism. Operation time, blood loss, the anatomical and functional newly forming vagina were evaluated.
Background: The surgical management of the absence of the vagina is a complex problem and constitutes a significant technical challenge. As the laparoscopy has been an important tool for the treatment of uterovaginal anomalies, we evaluated the feasibility of laparoscopic vaginoplasty using an ileal segment retrospectively.
Methods: Totally 86 patients who underwent laparoscopic vaginoplasty using an ileal segment in Beijing Anzhen Hospital during February 2004 to July 2007 were enrolled in this study.
Objective: To evaluate the feasibility of laparoscopic vaginal reconstruction using an ileal segment in patients with vaginal atresia, male-female transsexual patients, or patients who had vaginal cancer.
Methods: A retrospective review of the records of 80 patients who underwent laparoscopic vaginoplasty between 2004 and 2007 at Beijing Anzhen Hospital, China.
Results: Nineteen (23.

Objective: To observe the association between angiotensin-converting enzyme (ACE) gene polymorphism and endothelial nitric oxide synthase (eNOS) gene polymorphism and risk of coronary artery disease (CAD) in Han Chinese.
Methods: The polymorphism in the ACE and eNOS gene were detected by using polymerase chain reaction-restriction fragment length polymorphism analysis, blood pressure (BP), blood lipids, blood glucose (BS), body mass index (BMI) and left ventricle eject fraction (LVEF) were determined 236 patients with CAD and 190 healthy individuals.
Results: The frequencies of DD genotype of ACE were higher and the II genotype were lower in CAD patients than in controls (P < 0.
Maximum likelihood (ML) approach is used for estimating recombination frequency based on the achiasmatic model and the corresponding software package is developed for constructing linkage maps for achiasmatic organisms (F2 populations). The detection of sex-linked markers is done through a chi-square test. Monte Carlo simulations were conducted for comparing estimation of recombination frequency and mapping powers between these two genetic models (chiasmatic and achiasmatic models) when the achiasmata occurs.
