Implantation metastasis from sigmoid colon cancer to rectal anastomosis proved by whole exome sequencing and lineage inference for cancer heterogeneity and evolution analysis: Case report and literature review.

It was estimated that 70% of patients with colorectal cancer were found to have viable exfoliated malignant cells in adjacent intestinal lumen. Exfoliated malignant cells had been reported to implant on raw surfaces, such as polypectomy site, anal fissure, anal fistula, hemorrhoidectomy wound, and anastomotic suture line. Tumors at anastomosis could be classified into four groups: local recurrence, local manifestation of widespread metastasis, metachronous carcinogenesis, and implantation metastasis.

Pregnancy and fetal outcomes of chronic hepatitis C mothers with viremia in China.

Background: Data that assess maternal and infant outcomes in hepatitis C virus (HCV)-infected mothers are limited.

Aim: To investigate the frequency of complications and the associated risk factors.

Methods: We performed a cohort study to compare pregnancy and fetal outcomes of HCV-viremic mothers with those of healthy mothers.

Significance of neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio and prognostic nutritional index for predicting clinical outcomes in T1-2 rectal cancer.

Background: Inflammation-related parameters have been revealed to have prognostic value in multiple caners. However, the significance of some inflammation-related parameters, including the peripheral blood neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR) and prognostic nutritional index (PNI), remains controversial in T1-2 rectal cancer (RC).

Methods: Clinical data of 154 T1-2 RC patients were retrospectively reviewed.

MicroRNA-17 induces epithelial-mesenchymal transition consistent with the cancer stem cell phenotype by regulating CYP7B1 expression in colon cancer.

MicroRNA-17 (miRNA-17/miR‑17) expression has been confirmed to be significantly higher in colorectal cancer tissues than in normal tissues. However, its exact role in colorectal cancer has not yet been fully elucidated. In this study, we found that miR-17 not only promoted epithelial-mesenchymal transition (EMT), but also promoted the formation of a stem cell-like population in colon cancer DLD1 cells.

Lipoxin A4 ameliorates ischemia/reperfusion induced spinal cord injury in rabbit model.

Ischemia/reperfusion (I/R) induced spinal cord injury is an important pathologic mechanism leading to the paraplegia observed after surgery to repairaortic aneurysms. This study aims to investigate the neuroprotective effects of Lipoxin A4 and its potential mechanism in a rabbit model with I/R spinal cord injury. Forty-five rabbits were randomly divided into three groups: sham group, I/R group and Lipoxin A4 group.

[Effect of n-3 polyunsaturated fatty acids on proliferation and apoptosis of human colon cancer cell].

Objective: To investigate the effects of n-3 polyunsaturated fatty acids(n-3PUFA) on human colorectal cancer cell line HT-29 and associated mechanism.

Methods: The effects of docosahexaenoic acid (DHA) on the proliferation and apoptosis on HT-29 human colorectal cancer cells were evaluated by MTT assay, cell morphology (Hoechst33258 dyeing), DNA gel electrophoresis, and flow cytometry. The content of n-6PUFA and n-3PUFA of the treated cells and the ratio of n-6/n-3PUFA were analyzed by chromatography.

2-Phenyl-1H-imidazol-3-ium hydrogen fumarate-fumaric acid (2/1).

The asymmetric unit of the title compound, C(9)H(9)N(2) (+)·C(4)H(3)O(4) (-)·0.5C(4)H(4)O(4), consists of one 2-phenyl-imidazolium cation, one hydrogen fumarate anion and half a fumaric acid mol-ecule, which lies on an inversion center. N-H⋯O and O-H⋯O hydrogen bonds connect the cations, anions and fumaric acid mol-ecules into sheets parallel to the (102) plane.

[Outcomes after transanal endoscopic microsurgery for early rectal cancer and risk factors associated with recurrence].

Objective: To investigate outcomes after transanal endoscopic microsurgery (TEM) for early rectal cancer, identify risk factors associated with recurrence, and explore the indication of TEM for rectal cancer.

Methods: Sixty patients with rectal cancer undergoing TEM between June 2006 and June 2009 in the Provincial Qianfoshan Hospital of Shandong University were included in this study and data were retrospectively analyzed.

Results: There were 12 patients with pTis rectal cancer, 38 with pT1 and 10 with pT2.

[Characteristics of the condylar movement traces during lateral excursion of the unilateral posterior buccal crossbite].

Purpose: To investigate the characteristics of the condylar movement traces during lateral excursion of the unilateral posterior buccal crossbite and to compare the difference with the individual ideal occlusion.

Methods: Twenty-six subjects with normal occlusion and 26 subjects with unilateral posterior buccal crossbite were tested by CADIAX for the condylar movement. The lateral excursion traces were recorded.

[Fast image denoising based on mathematical morphology].

There is a contradiction between image denoising and protection of the useful information in the image. To deal with this contradiction, we use the approach of mathematical morphology. In this paper, we expound the method and effectivity of mathmatical morphology in image processing.

[Study on the changes of T-lymphocyte subsets in the patients with endometriosis].

Objective: To investigate the function of T-lymphocyte subsets in patients with endometriosis.

Methods: The levels of interleukin-2 (IL-2) and interleukin-6 (IL-6) in the serum, and peritoneal fluid of 30 cases with endometriosis were detected using enzyme linked immunoabsorbent assay and compared with those of 20 non-endometriosis cases. The expression of IL-2 and IL-6 in ectopic endometrial tissue from the patients with endometriosis and the endometrial tissues of 10 normal women was investigated by immunohistochemistry method.
