Contrast-enhanced ultrasonography findings of LAMNs with peritoneal and splenic metastases: a case report and literature review.

Low-grade appendiceal mucinous neoplasms (LAMNs) are rare appendiceal tumors that are primarily diagnosed using computed tomography(CT) enhancement and magnetic resonance imaging (MRI). Herein, we report the sonographic features, especially for contrast-enhanced ultrasound (CEUS), of a 70-year-old female with an unusual LAMN metastasizing to the peritoneum and spleen. The patient had a right pelvic mass 2 days prior to presentation.

The estrogen/miR-338-3p/ADAM17 axis enhances the viability of breast cancer cells via suppressing NK cell's function.

Natural killer (NK) cells are the critical elements of the innate immune response and implicated in rapidly recognizing and eliminating cancer cells. However, the tumor-suppressive ability of NK cells is often impaired in several cancer types. The critical roles of microRNAs have been elucidated by increasing evidences, while the regulation of miR-338-3p in anti-tumor activation of NK cells and its relationship with estrogen in breast cancer (BC) are still confusing.

Downregulated Expression of linc-ROR in Gastric Cancer and Its Potential Diagnostic and Prognosis Value.

Background: Gastric cancer (GC) is one of the global mortality diseases and has a poor prognosis due to the lack of ideal tumor biomarkers. Numerous studies have shown that long noncoding RNAs (lncRNAs) can affect the occurrence and development of cancer through a variety of signaling pathways. The abnormal expression and specificity of lncRNAs in tumors make them potential biomarkers of cancers.

Circ-ZNF609 promotes migration of colorectal cancer by inhibiting Gli1 expression via microRNA-150.

Purpose: To investigate the effect of circular (circ)-ZNF609 on the pathogenesis of colorectal cancer and its underlying mechanism.

Methods: 24 cases of postoperative colorectal cancer tissues and 36 cases of mucosa tissues were selected as experimental group and control group, respectively. Circ-ZNF609 expression in colorectal cancer tissues and mucosa tissues were detected by quantitative real-time PCR (qRT-PCR).

Safety and efficacy of laparoscopy-assisted gastrectomy for advanced gastric cancer in the elderly.

To evaluate safety and efficacy of laparoscopy-assisted radical gastrectomy (LARG) for advanced gastric cancer patients aged 70 years or older. Clinical data were retrospectively collected from patients with IIA-IIIC gastric cancer who underwent LARG (n = 30) and open radical gastrectomy (ORG, n = 34) in Department of Gastrointestinal Surgery in the Ningbo First Hospital from January 2012 to December 2013. The mean operative time was longer in the LARG group than in the ORG group but there was no statistical difference between the two groups.

Adult Hirschsprung's disease: report of four cases.

Adult Hirschsprung's disease (HD) is a rare motor disorder of the gut that is frequently misdiagnosed as refractory constipation. The primary pathogenic defect in adult HD is identical to that seen in infancy or childhood, and is characterized by the total absence of intramural ganglion cells of the submucosal (Meissner) and myenteric (Auerbach) neural plexuses in the affected segment of the bowel. Ninety-four percent of HD cases are diagnosed before the patient reaches 5 years of age, however, on rare occasion, mild cases of HD may go undiagnosed until he or she reaches adulthood.

[Application of SELDI-TOF-MS in detection of liver metastasis from colorectal cancer].

Objective: To establish a serum protein fingerprint model for prediction of liver metastasis from colorectal cancer by SELDI-TOF-MS analysis, and to determine the differentiatial proteins associated with the metastatic liver cancers.

Methods: Data were collected from the Department of General Surgery in Zhongshan Hospital. A group of patients with colorectal cancer (CRC) without liver metastasis (n = 36) and another group with liver metastasis (n = 36) were included in this study.

The effect of combination treatment with docosahexaenoic acid and 5-fluorouracil on the mRNA expression of apoptosis-related genes, including the novel gene BCL2L12, in gastric cancer cells.

Docosahexaenoic acid (DHA) plays an important role in suppressing the growth of cancer. In this paper, the synergetic anticancer effect of combination DHA with 5-fluorouracil (5-FU) was investigated in gastric carcinoma cells. We found that DHA inhibited the growth of cultured SGC7901 cells at different concentrations in a dose- and time-dependent manner.
