Epigenetic changes in peripheral leucocytes as biomarkers in intrauterine growth retardation rat.

Epigenetics plays an important role in the fetal origins of adult disease. Intrauterine growth retardation (IUGR) can cause increased histone acetylation of the endothelin-1 () gene from pulmonary vascular endothelial cells or the whole lung tissue and persist into later life, likely resulting in increased risk of pulmonary hypertension or asthma later in life. However, little is known regarding the correlation of epigenetic changes between specific tissue and peripheral leucocytes.

Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy improves survival of patients with peritoneal carcinomatosis from gastric cancer: final results of a phase III randomized clinical trial.

Background: This randomized phase III study was to evaluate the efficacy and safety of cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) for the treatment of peritoneal carcinomatosis (PC) from gastric cancer.

Methods: Sixty-eight gastric PC patients were randomized into CRS alone (n = 34) or CRS + HIPEC (n = 34) receiving cisplatin 120 mg and mitomycin C 30 mg each in 6000 ml of normal saline at 43 ± 0.5°C for 60-90 min.

Postoperative recurrence in gastric cancer: analysis of 59 cases.

Background/aims: Gastric cancer (GC) is the leading cause of death in China. Although surgery based comprehensive treatment is the best approach to improve survival, postoperative recurrence is a major problem. This study was aimed to find out the relationship of cancer recurrence with major clinico-pathological factors, with special attention focused on time of recurrence.

Expression of cyclooxygenase-2 in colorectal cancer and its clinical significance.

Aim: To clarify the clinicopathologic significance of COX-2 expression in human colorectal cancer.

Methods: A total of 128 surgically resected colorectal cancer specimens were immunohistochemically analyzed with the use of anti-COX-2, anti-VEGF and anti-MMP-2 antibodies. The relationship between the cyclooxygenase-2 expression in primary lesions of colorectal cancer and clinicopathologic parameters was evaluated by chi-square test.

[Clinical significance of detecting lymph node micrometastasis of colorectal cancer by reverse transcriptase-polymerase chain reaction (RT-PCR)].

Background & Objective: It remains controversial whether lymph node micrometastasis has impact on staging and prognosis of colorectal cancer. This study was to compare the sensitivity of reverse transcriptase- polymerase chain reaction (RT-PCR) in detecting lymph node micrometastasis of colorectal cancer with pathological morphology and immunohistochemistry, and assess the impact of lymph node micrometastasis on clinical staging and prognosis of colorectal cancer.

Methods: Lymph nodes from 56 cases of colorectal cancer radical resection specimens were studied by RT-PCR to detect the expression of cytokeratin 20 (CK20) mRNA, and compared with routine pathology detection using hematoxylin and eosine (HE) staining, and immunohistochemistry using monoclonal antibody specifically against CK20.

Cyclooxygenase-2 expression and angiogenesis in colorectal cancer.

Aim: Cyclooxygenase-2 is involved in a variety of important cellular functions, including cell growth and differentiation, cancer cell motility and invasion, angiogenesis and immune function. However, the role of cyclooxygenase-2 as an angiogenic factor in colorectal cancer tissue is still unclear. We investigated the relationship between cyclooxygenase-2 and angiogenesis by analyzing the expression of cyclooxygenase-2 in colorectal cancer tissue, as well as its association with vascular endothelial growth factor (VEGF) and microvascular density (MVD).
