Abstract
Colorectal cancer (CRC) is one of the most common and deadly cancers in the world. However, no effective treatment for the disease has yet been found. For this reason, several studies are being carried out on the treatment of CRC. Currently, there is limited understanding of the role of CPNE7 (copine-7) in CRC progression and metastasis. The results of this study show that CPNE7 exerts an oncogenic effect in CRC. First, CPNE7 was shown to be significantly up-regulated in CRC patient tissues and CRC cell lines compared to normal tissues according to IHC staining, qRT-PCR, and western blotting. Next, this study used both systems of siRNA and shRNA to suppress CPNE7 gene expression to check the CPNE7 mechanism in CRC. The suppressed CPNE7 significantly inhibited the growth of CRC cells in in vitro experiments, including migration, invasion, and semisolid agar colony-forming assay. Moreover, the modified expression of CPNE7 led to a decrease in the levels of genes associated with epithelial-mesenchymal transition (EMT). The epithelial genes E-cadherin (CDH1) and Collagen A1 were upregulated, and the levels of mesenchymal genes such as N-cadherin (CDH2), ZEB1, ZEB2, and SNAIL (SNAL1) were downregulated after CPNE7 inhibition. This study suggests that CPNE7 may serve as a potential diagnostic biomarker for CRC patients.

Abstract
BACKGROUND Leiomyosarcoma (LMS) has a poor prognosis and rarely originates from the colon. If resection is possible, surgery is the first treatment most commonly considered. Unfortunately, no standard treatment exists for hepatic metastasis of LMS; although, several treatments, such as chemotherapy, radiotherapy, and surgery, have been used. Subsequently, the management of liver metastases remains controversial.
CASE SUMMARY We present a rare case of metachronous liver metastasis in a patient with LMS originating from the descending colon. A 38-year-old man initially reported abdominal pain and diarrhea over the previous two months. Colonoscopy revealed a 4-cm diameter mass in the descending colon, 40 cm from the anal verge. Computed tomography revealed intussusception of the descending colon due to the 4-cm mass. The patient underwent a left hemicolectomy. Immunohistochemical analysis of the tumor revealed that it was positive for smooth muscle actin and desmin, and negative for cluster of differentiation 34 (CD34), CD117, and discovered on gastrointestinal stromal tumor (GIST)-1, which are characteristic of gastrointestinal LMS. A single liver metastasis developed 11 mo post-operatively; the patient subsequently underwent curative resection thereof. The patient remained disease-free after six cycles of adjuvant chemotherapy (doxorubicin and ifosfamide), and 40 and 52 mo after liver resection and primary surgery, respectively. Similar cases were obtained from a search of Embase, PubMed, MEDLINE, and Google Scholar.
CONCLUSION Early diagnosis and surgical resection may be the only potential curative options for liver metastasis of gastrointestinal LMS.

Abstract
G protein-coupled receptor 56 (GPR56) belongs to the adhesion G protein-coupled receptor subfamily, which plays a role in cell progression and survival. The aim of this study was to investigate the role of the GPR56 gene in a cell line study and the impact of its protein expression on the prognosis of colorectal cancer (CRC) patients. The effect of GPR56 on tumor cell proliferation (WST-1 assay), invasion (Transwell assay), migration (Transwell assay, wound healing assay), and colony-forming ability (semisolid agar colony-forming assay) was explored. The expression levels of GPR56 in tissue samples of 109 CRC patients were evaluated by immunohistochemistry. The prognostic value of GRP56 was analyzed using univariate and multivariate analyses. The downregulation of GPR56 in the CRC cell line reduced cell proliferation as compared with that in a control sample (48 h; p=0.042, 72 h; p=0.001). Downregulation of the GPR56 expression reduced cell invasion and migration abilities and inhibited colony-forming abilities (p<0.005). The 5-year overall survival rate was worse in the high-expression group as compared with that in the low-expression group (51.6% vs. 74.4%, p=0.008). High GPR56 expression was a significant prognostic factor for overall survival of CRC patients in the univariate (p=0.001) and multivariate (p<0.001) analyses. The expression level of GPR56 plays an important role in tumor progression in CRC, and it may serve as a prognostic indicator in CRC patients.

Abstract
Bacterial diversity of two Lake Baikal endemic sponges characterized by different life forms, branching Lubomirskia baicalensis and cortical Baikalospongia sp., was studied using the method of 454 pyrosequencing of the 16S rRNA gene fragments. In the communities associated with L. baicalensis and Baikalospongia sp., 426 and 428 OTUs, respectively, were identified. In microbial associations of these spong- es, 24 bacterial phyla were identified, with predominance of Bacteroidetes, Proteobacteria, and Actinobacteria. Analysis of the taxonomic composition of bacterial communities of the sponges was carried out by search of the dominant phylotypes within the phylum level cluster. Comparison of bacterial associations of the sponges with Lake Baikal bacterioplankton revealed both the shared OTUs and the unique ones characteristic of the studied species.

Abstract
The aim of this study was to evaluate the use of total coliforms (TC) and faecal coliforms (FC) using a membrane filtration method for precise monitoring of faecal pollution in Korean surface water. The samples were collected in Korea from both main rivers and their tributaries. Presumptive TC * FC were enumerated. The ratios of presumptive FC to TC were not constant, but varied widely, and TC were difficult to enumerate because of overgrowth by background colonies. For FC this was not the case. Seven hundred and three purified strains of presumptive TC * FC and their background colonies were biotyped using API 20E. Among 272 presumptive TC, non-faecal related species, Aeromonas hydrophila dominated (34.6%) and E. coli accounted for only 5.1%. In contrast, E. coli made up 89% of the 209 presumptive FC. Furthermore, of 164 background colonies on Endo Agar LES, 54.9% was A. hydrophila, while background colonies on m-FC Agar were few (58 strains), and despite their atypical colony appearance, most of them were biotyped as enteric bacteria. These results reveal that the detection of FC rather than TC using m-FC Agar is more appropriate for faecal pollution monitoring in eutrophicated surface water located in a temperate region.

Abstract
OBJECTIVE Total abdominal and vaginal hysterectomies have been performed by extrafascial enucleation of the uterus with amputation of the upper vagina. Our new method, which is limited to an intrafascial cylindriform enucleation of the cervix, leaves intact the highly vascularized extrafascial cervical tissue, the corresponding nerves, and the topography of the ureters. STUDY DESIGN From December 1991 to December 1992, 60 patients underwent an intrafascial hysterectomy by pelviscopy and two patients by laparotomy for leiomyomas, endometriosis, and other intractable bleeding disorders and for a variety of additional benign gynecologic diseases. Uterine extirpation was performed in the classic manner with grasping forceps, scissors, ligatures, and sutures. No electrosurgical equipment, stapling devices, or lasers were used. RESULTS We analyzed our cases according to intraoperative, immediate postoperative, and late postoperative complications. We had no major complications. Average operating time is compatible with that of conventional total abdominal or vaginal and laparoscopy-assisted vaginal hysterectomy. Blood loss was minimal (average drop of hemoglobin 1.8 gm). Average hospitalization was 50.6 hours. CONCLUSION There has never been an indication for the removal of the normal cervix at hysterectomy, other than for cancer prophylaxis. The synthesis of supracervical extirpation of the uterus, conization of the cervix, and operative laparoscopy (pelviscopy) enables us to perform a truly laparoscopic hysterectomy without colpotomy. Pelvic floor support is maintained and transvaginal sexual sensation is less likely to be impaired because of the preservation of the cardinal and uterosacral ligaments. With the serrated-edge macromorcellator, morcellated cylinders of cervical and uterine body tissue guarantee a thorough histologic examination and interpretation. Physical stress to the patient is minimized. There are no abdominal or vaginal incisions. The abdominal space remains practically unopened. Pelviscopic intrafascial hysterectomy equates with minimally invasive and organ-preserving surgery. It may be sufficient for cervical and endometrial cancer prophylaxis.
