Efficacy of the No. 10 lymphadenectomy with spleen preservation on patients with gastric cancer and/or esophagogastric junction adenocarcinoma who underwent total gastrectomy: a systematic review and meta-analysis.

Background: Surgery with total gastrectomy and D2 lymph node dissection (LND) has been recommended as the standard treatment for patients with advanced upper and middle gastric carcinoma and/or Siewert type II/III adenocarcinoma of the esophagogastric junction (AEG). However, whether the No. 10 lymph node (No.

Expression heterogeneity research of ITGB3 and BCL-2 in lung adenocarcinoma tissue and adenocarcinoma cell line.

Objective: To analyze expression heterogeneity of Integrin beta 3 (ITGB3) and B-cell lymphoma 2 (BCL-2) in lung adenocarcinoma tissue and adenocarcinoma cell line and further provide theoretical direction for molecular biological research of lung adenocarcinoma.

Methods: Tissue microarray was used to observe relation among expression, heterogeneitpy and clinical characteristics of ITGB3 and BCL-2 in lung cancer.

Results: ITGB3 and BCL-2 increased significantly in A549 cells in CAFs group withβ-actin as control; the expression level of BCL-2 also increased in ITGB3 transfected cells with GFP plasmid transfected A549 cells as control; immunohistochemistry staining showed that positive rates of ITGB3, ITGB1 and BCL-2 in normal lung tissues were 0, the positive rates in lung adenocarcinoma were 7.

[KRAS and epidermal growth factor receptor gene mutation in non-small cell lung cancer].

Objective: To study KRAS and epidermal growth factor receptor (EGFR) mutations in primary non-small cell lung cancer (NSCLC) and their association with the effects of targeted therapy.

Methods: Gene mutations of KRAS and EGFR in both primary tumors and local lymph node metastases from 150 patients with NSCLC were analyzed by direct sequencing. Twelve of the patients were given gefitinib as neoadjuvant therapy after EGFR-TKI sensitive mutations had been detected in biopsies of mediastinal lymph node metastases.

Construction of a plasmid vector for liver-specific inhibition of hepatocyte nuclear factor 4 alpha expression.

Hepatocyte nuclear factor-4alpha (HNF-4a) is an important transcription factor in the liver, and regulates a large number of genes involved in many aspects of hepatocyte functions. In this study, a liver-specific transcriptional regulatory element comprised of albumin promoter (ALBp) and alpha-fetoprotein enhancer (AFPe) was obtained and cloned into the plasmid pHNF4sh-CMV(short hairpin RNA targeting HNF4α) with original CMV promoter removed, resulting to pHNF4sh-EP for liver-specific knockdown of HNF4α expression. In an attempt to verify its characteristics, pHNF4sh-EP was transfected to L02, HepG2, and COS1 cell lines in vitro and delivered into mice in vivo.

Nucleoside analogue can improve the long-term prognosis of patients with hepatitis B virus infection-associated acute on chronic liver failure.

Background: The prognosis of patients with hepatitis B virus (HBV)-associated acute on chronic liver failure (ACLF) is extremely poor.

Aim: This study was designed to evaluate the efficacy and safety of nucleoside analogue treatment of patients with HBV-associated ACLF.

Methods: We used a retrospective review of eligible patients from April 2006 to December 2008.

Recombinant human hepatocyte growth factor for liver failure.

The purpose of this paper is to evaluate the efficacy and safety of recombinant human hepatocyte growth factor (rh-HGF) for liver failure (LF) using meta-analysis of data from the literature involving available randomized controlled trials of rh-HGF plus comprehensive therapy (CT) compared with that of CT alone (Therapy I versus II) in treating LF. We searched the Cochrane Library, MEDLINE, EMBASE, CBMdisc, and CNKI as well as employing manual searches. Based on our search criteria, we found 21 trials, involving 5902 patients.
