Background: The CRC-VTE trial conducted in China revealed a significant occurrence of venous thromboembolism (VTE) in patients following colorectal cancer (CRC) surgery, raising concerns about implementing thromboprophylaxis measures. The present study aimed to identify and analyze inappropriate aspects of current thromboprophylaxis practices.
Methods: This study performed an analysis of the CRC-VTE trial, a prospective multicenter study that enrolled 1836 patients who underwent CRC surgery.

Background: Venous thromboembolism (VTE) is a common and serious complication after colorectal cancer (CRC) surgery. Few large-sample studies have reported VTE incidence and management status after CRC surgery in China. This study aimed to investigate the incidence and prevention of VTE in Chinese patients after CRC surgery, identify risk factors for developing VTE, and construct a new scoring system for clinical decision-making and care planning.

It has been demonstrated that EDDM3A expression is upregulated and promotes cell proliferation in non-small cell lung cancer (NSCLC). However, the role of EDDM3A in other types of human cancers, including gastric cancer (GC), is still unexplored.

In this study, we aimed to explore the the role of DSCAM-AS1 in gastric carcinoma. Expression of DSCAM-AS1 mRNA, miR-204, and TPT1 (Tumor Protein, Translationally-Controlled 1) were detected using quantitative real-time polymerase chain reaction (qRT-PCR).

As a newly identified lncRNA, the role of XIST in colorectal cancer (CRC) has not been established. Here, we sought to characterize the role of XIST and its associated regulatory network in CRC cells.

Methods: Eight single nucleotide polymorphisms (SNP) were genotyped in 505 CRC patients and 510 controls. The association between candidate SNPs and risk of CRC were evaluated using odds ratio (OR), 95% confidence interval (95% CI).
Background: Hypoxia-inducible factor 1α (HIF-1α) plays an important role in regulating cell survival and angiogenesis, which are critical for tumor growth and metastasis. Genetic variations of HIF1A have been shown to influence the susceptibility to many kinds of human tumors. Increased expression of HIF-1α has also been demonstrated to be involved in tumor progression.

In the present study, we present a case of IMT in a 56-year-old female patient who was admitted to our hospital due to a mass found in her right breast. Mammogram and ultrasound revealed a well-circumscribed mass and surgery was performed.

In this study, a tissue microarray consisting of 360 individual samples from three different breast tissues was generated. By comparing the expression of the tumor-suppressor genes (BRCA1, BECN1, CCND1, PTEN and UVRAG) in ductal breast cancer and normal breast tissues, respectively, we were able to assign changes in the expression of these mRNAs to specific stages and allocate them to define the roles in the multi‑step process of breast carcinogenesis.

Erdheim-Chester disease (ECD) is a rare non-Langerhans form of histiocytosis characterized by xanthomatous tissue infiltration with foamy histiocytes. It is still controversial whether these histiocytic proliferations represent monoclonal neoplastic populations or are part of a polyclonal reactive process. This is a case report of ECD in a 76-year-old Chinese woman.

The purpose of the present study is to explore the biological behavior of PTD-BCR/ABL SH3 fusion protein in hepatocarcinoma cells in vitro and in vivo.
Methods: HepG-2 cells were cocultured with the fusion protein for the indicated time and studied in vitro by immunocytochemistry staining to demonstrate the localization of the protein, light and electron microscope observation in morphology research, MTT assay to draw a growth curve and to analyze inhibition ratio, DNA ladder and TUNEL staining to study apoptosis.

Snail functions as a key regulator in the induction of a phenotypic change called epithelial to mesenchymal transition (EMT). Aberrant expression of Snail prevails in the onset and development of tumor. Here, we have observed increased expression of Snail under the treatment of hydrogen peroxide (H(2)O(2)).

Methods: Human colorectal carcinoma cell lines SW480 transfected with G1CEACDNa were cultured. The proliferated colonies were treated with the combined therapy of 5-FC and hyperthermia at a temperature of 43 degrees C for 30 min.
Objective: With the pComb3X-displaying Fab antibody libraries, to achieve the humanization of murine HAb18 against HCC by guided selection.
Methods: With the optimized primers, the human Fd and C(L) repertoire genes were amplified by RT-PCR from PBMC of HCC patients. The Fd repertoire genes were paired with murine HAb18 C(L) gene to construct pComb3X-displaying hybrid Fab library.
Background & Objective: It has been proved that vital signs of organism can be influenced by heat infusion and the thermochemotherapy with Adriamycin (ADM) is more effective than the general chemotherapy in inhibiting extraneous rabbit VX-2 cells. Intermittent thermochemotherapeutic infusion and continuous thermochemotherapeutic infusion with ADM were performed respectively on the rabbits to evaluate the effectiveness and safety of intermittent thermochemotherapeutic intra artery infusion by comparing their respiration rate, heart rate, body temperature, and the ADM concentration in VX-2 carcinoma.
Methods: VX-2 tumor models were established in the hind legs of 30 New Zealand rabbits, and then they were divided into three groups (10 in each group) randomly.
