Abstract
BACKGROUND Cell metabolism and long noncoding RNA (lncRNA) played crucial roles in cancer development. However, their association in colon adenocarcinoma (COAD) remains unclear. METHODS The COAD gene expression data and corresponding clinical data were retrieved from The Cancer Genome Atlas (TCGA) database. Differential expression of metabolic genes and lncRNA were identified by comparing tumor and normal colon tissues. Pearson correlation analysis was performed to identify metabolism-associated lncRNA. COAD patients were divided into training cohort and validation cohort by randomization. Then, a univariate Cox regression analysis was introduced to evaluate the correlations between metabolism-related lncRNAs and overall survival (OS) of the patients in the training cohort. The least absolute shrinkage and selection operator (LASSO) method was introduced to determine and establish a prognostic prediction model. Subsequently, survival analysis, receiver operating characteristic (ROC) curve analysis, and Cox regression analysis were generated to estimate the prognostic role of the LncRNA risk score in training, validation, and entire cohorts. RESULTS We identified 152 differentially expressed metabolism-associated lncRNAs (MRLncRNAs). A prognostic prediction model involving four metabolism-related lncRNAs were established using LASSO. In each cohort, COAD patients in the high-risk group had worse OS compared to those in the low-risk group. The ROC analyses demonstrated that the lncRNA signature performed well in predicting OS. Uni- and multivariate analysis indicated that the lncRNA signature as an independent prognostic factor. Furthermore, a correlation analysis demonstrated that LINC01138 was the most closely lncRNA related to metabolic genes. In vitro assays demonstrated that LINC01138 affects tumor progression in COAD. CONCLUSIONS In summary, we established a metabolism-associated lncRNAs model to predict the prognosis in COAD patients.

Abstract
Background Non-invasive prenatal screening (NIPS) using cell-free foetal DNA (cfDNA) has been widely used for identifying common foetal aneuploidies (e.g. trisomy 21 (T21), trisomy (T18) and trisomy 13 (T13)) in clinical practice. The sensitivity and specificity of NIPS exceeds 99%, but the positive prediction value (PPV) is approximately 70% (combined T21, T18 and T13). Thus, some 30% of pregnant women who have positive NIPS results are eventually identified as normal by amniocentesis. These women therefore must undertake needless invasive tests and risk miscarrying healthy babies because of false positive NIPS results. Methods In order to achieve higher accuracy, we amended the standard NIPS (s-NIPS) protocol with an additional cfDNA size selecting step in agarose-electrophoresis. The advantage of the new method (named e-NIPS) was validated by comparing the results of e-NIPS and s-NIPS using 114 retrospective cases selected from 15,930 cases. Results Our results showed that the foetal cfDNA fraction can be enriched significantly by a size selection step. With this modification, all 98 negative cases and 9 of 11 false positive cases of s-NIPS were correctly identified by e-NIPS, resulting in an increased PPV from 71% to 77%. Additionally, a simulation test showed that e-NIPS is more reliable than s-NIPS, especially when the foetal cfDNA concentration and sequencing coverage are low. Conclusion cfDNA size selection is an important step in improving the accuracy of non-invasive prenatal screening for chromosomal abnormalities.

Abstract
This study aimed to investigate the mechanism underlying the inhibitory effect of tumor suppressor gene miR-186 and zinc finger protein 545 (ZNF545) on the proliferation of multiple myeloma (MM) cells. CD138 magnetic beads were used to isolate different types of myeloma cell lines (KM3, U266, RPMI-8226, and H929), which were then infected by lentivirus carrying the miR-186 gene. Using uninfected myeloma cells as the control, MTT [3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide, Thiazolyl Blue Tetrazolium Bromide] assay was performed to calculate the rate of cell proliferation at different time points. In addition, the correlation between the expression of Jagged 1 and miR-186 was analyzed by real-time Polymerase Chain Reaction (PCR). Furthermore, the effect of 5-Aza-2-deoxycytidine and acetylase inhibitor Trichomycin A (TSA) on the expression of ZNF545 and proliferation/apoptosis of MM cells was investigated using Reverse Transcription-Polymerase Chain Reaction (RT-PCR), Western blotting (WB), MTS [3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium] cell proliferation assay, and Annexin V-FITC/PI staining. Compared with the control group, the proliferation of miR-186-overexpressing U266 and RPMI-8226 cells was significantly decreased. In cell cloning experiments, miR-186 decreased the number of U266 and RPMI-8226 clones while reducing the protein expression of Jagged 1. The expression level of ZNF545 in myeloma patients was also reduced to some extent. ZNF545 protein also promoted the apoptosis of myeloma cells. By inhibiting the proliferation of myeloma cells, miR-186 gene and ZNF protein may be used as tumor suppressors in the treatment of myeloma.

Abstract
A 67-year-old man from Jingzhou was admitted to the First Hospital Affiliated to Yangtze University in July 2013 with sudden onset of abdominal pain with dizziness for 12 h. The patient had sign of peritoneal irritation. Ultrasonography of the abdomen and pelvis showed hepatic fibrosis due to schistosomiasis. Computed tomography showed free gas in the peritoneal cavity. Plain abdominal radiography showed bilateral subdiaphragmatic accumulation of gas, perforation of the viscus, and radio-opacity in the left renal area. The patient underwent emergency exploratory laparotomy. At laparotomy, a moderate amount of muddy yellow pus was found in the intra-abdominal cavity. At the junction of the jejunum and ileum, about 250 cm from Treitz’s ligament, there was an about 10-cm length of inflamed small bowel with perforation (3 mm in diameter) along the mesenteric border at the middle of the lesion. The patient underwent resection of the affected intestinal segment, along with end-to-end intestinal anastomosis. Histopathological examination revealed mucosal necrosis and hemorrhage with a large number of infiltrating eosinophils and neutrophils, and acute submucosal inflammation with a large number of infiltrating eosinophils and neutrophils associated with Schistosoma japonicum (S. japonicum) eggs. No intravascular adult parasite was found. Postoperatively, the patient was treated with praziquantel (30 mg/kg daily) for 4 d. The patient progressed well. To the best of our knowledge, this is the first case of small bowel perforation associated with eggs of S. japonicum.

Abstract
AIM: To investigate the effects of curcumin on the microcirculation in early-stage ischemia/reperfusion injury in rats.
METHODS: Wistar rats were randomized into three groups: sham-operation group, dimethyl sulfoxide (DMSO) group (treated with 1 mL of DMSO twice) and curcumin group (treated with 40 mg/kg of curcumin twice). The level of serum transaminase, the content of hepatic nitric oxide (NO), and the expression of nitric oxide synthase (NOS), inducible nitric oxide synthase (iNOS) and endothelial nitric oxide synthase (eNOS) mRNAs in liver tissue were determined to evaluate the effects of curcumin on the microcirculation in early-stage ischemia/reperfusion (reperfusion for 1 h and 3 h).
RESULTS: Compared with the DMSO group, curcumin decreased the levels of serum alanine transaminase (603.8 U/L ± 64.5 U/L vs 758.1 U/L ± 114.7 U/L and 837.1 U/L ± 33.3 U/L vs 1012.7 U/L ± 119.8 U/L, respectively; both P < 0.01) and aspartate aminotransferase (605.7 U/L ± 65.7 U/L vs 779.5 U/L ± 124.3 U/L and 849.6 U/L ± 36.0 U/L vs 1027.8 U/L ± 139.8 U/L, respectively; both P < 0.01), relieved hepatic pathological damage, reduced the content of NO (0.455 ± 0.056 vs 0.594 ± 0.087 and 0.492 ± 0.040 vs 0.671 ± 0.079, respectively; both P < 0.01) derived from iNOS, and down-regulated the expression of iNOS mRNA (0.426 ± 0.075 vs 0.569 ± 0.073 and 0.527 ± 0.066 vs 0.702 ± 0.089, respectively; both P < 0.01) in the liver tissue in early-stage ischemia/reperfusion (reperfusion for 1 h and 3 h).
CONCLUSION: Curcumin can relieve hepatic cell injury by decreasing the content of NO derived from iNOS and reducing hepatic microcirculation disturbance in early-stage ischemia/reperfusion injury in rats.

Abstract
AIM: To compare the efficacy of end-to-end invaginated pancreaticojejunostomy, duct-to-mucosa pancreaticojejunostomy and binding pancreaticojejunostomy.
METHODS: The clinical data of 157 patient who underwent pancreaticoduodenectomy at our hospital from February 1999 to May 2009 were collected. Of all patients, 61 underwent end-to-end invaginated pancreaticojejunostomy, 66 underwent duct-to-mucosa pancreaticojejunostomy and 30 underwent binding pancreaticojejunostomy. The anastomotic time, postoperative complications, death rate and length of stay were compared.
RESULTS: The mean time to complete end-to-end invaginated pancreaticojejunostomy, duct-to-mucosa pancreaticojejunostomy and binding pancreaticojejunostomy was 35.85 ± 4.73, 37.18 ± 6.12 and 20.75 ± 4.05 min, respectively. The mean time to complete binding pancreaticojejunostomy was significantly shorter than that to complete end-to-end invaginated pancreaticojejunostomy and duct-to-mucosa pancreaticojejunostomy (both P < 0.05). No significant differences were noted in complication rate, mortality rate and length of stay among the three groups. No pancreatic leakage was observed after binding pancreaticojejunostomy.
CONCLUSION: Satisfactory efficacy and low complication rate can be achieved using any of the three methods of pancreaticojejunostomy. Binding pancreaticojejunostomy has more convenient procedure, shorter operative time and less complications than the other two methods.

Abstract
AIM: To investigate the hypothesis that the protective effects of curcumin in hepatic warm ischemia/reperfusion (I/R) injury are associated with increasing heat shock protein 70 (Hsp70) expression and antioxidant enzyme activity.
METHODS: Sixty Sprague-Dawley male rats were randomly divided into sham, I/R, C + I/R groups. The model of reduced-size liver warm ischemia and reperfusion was used. Curcumin (50 mg/kg) was administered by injection through a branch of superior mesenteric vein at 30 min before ischemia in C + I/R group. Five rats were used to investigate the survival during 1 wk after operation in each group. Blood samples and liver tissues were obtained in the remaining animals after 3, 12, and 24 h of reperfusion to assess serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), liver tissue NO2- + NO3-, malondialdehyde (MDA) content, superoxide dismutase (SOD), catalase (CAT), nitricoxide synthase (NOS) and myeloperoxidase (MPO) activity, Hsp70 expression and apoptosis ratio.
RESULTS: Compared with I/R group, curcumin pretreatment group showed less ischemia/reperfusion-induced injury. CAT and SOD activity and Hsp70 expression increased significantly. A higher rate of apoptosis was observed in I/R group than in C + I/R group, and a significant increase of MDA, NO2- + NO3- and MPO level in liver tissues and serum transaminase concentration was also observed in I/R group compared to C + I/R group. Curcumin also decreased the activity of inducible NO synthase (iNOS) in liver after reperfusion, but had no effect on the level of endothelial NO synthase (eNOS) after reperfusion in liver. The 7 d survival rate was significantly higher in C + I/R group than in I/R group.
CONCLUSION: Curcumin has protective effects against hepatic I/R injury. Its mechanism might be related to the overexpression of Hsp70 and antioxidant enzymes.

Abstract
BACKGROUND Big Endothelin-1 levels increase significantly in patients with various tumors, and raised plasma concentrations are associated with worse outcome. The aim of this study was to investigate plasma Big Endothelin-1 levels in patients with gastric carcinoma before and after radical gastrectomy and to explore its clinical significance. MATERIALS AND METHODS One hundred and six patients with gastric carcinoma and 20 controls were studied. Big Endothelin-1 plasma levels in patients with advanced gastric cancer were examined by enzyme-linked immunosorbent assay before and on days 1, 3 and 10 after curative surgery and were then tested every 3 months. RESULTS All patients, except those with stage I gastric cancer, had significantly higher mean plasma Big Endothelin-1 levels compared with the normal controls (p = 0.000). The plasma Big Endothelin-1 levels were markedly increased on the first post-operative day (1st POD) in all patients but decreased on the 3rd POD with no significant difference compared to the pre-operative levels. On the 10th POD, patients with stages I and II gastric cancer showed a marked reduction in the plasma Big Endothelin-1 levels (p=0.010 and p=0.000, respectively), whereas no significant difference was observed in stage III and IVpatients. During the follow-up, plasma Big Endothelin-1 levels immediately before recurrences occurred in stage II patients were significantly higher compared with the levels on the 10th POD (p=0.011). CONCLUSION Plasma Big Endothelin-1 levels might be a reliable marker to determine the severity of gastric carcinoma. Monitoring plasma Big Endothelin-I levels after curative resection in stage II gastric cancer patients was valuable in predicting recurrences.

Abstract
BACKGROUND/AIMS We conducted a preliminary study to determine the feasibility of therapy consisting of intraoperative radiofrequency thermal ablation combined with portal vein infusion chemotherapy and transarterial chemoembolization (IRFAPA) for unresectable hepatocellular carcinoma (HCC). METHODOLOGY Between September 2001 and June 2004, 34 patients with unresectable HCC were enrolled into a prospective study. 18 cases underwent IRFAPA (group I and 16 cases underwent percutaneous RF ablation (PRFA, group II). Patients' outcomes for IRFAPA and PRFA were recorded and compared. RESULTS Patients undergoing IRFAPA or PRFA were similar in age, liver function, tumor size, serum AFP, distribution of tumor, mortality, complication and complete ablation rates. In five patients in group II seven new lesions were found during operation. The rate of distant intrahepatic recurrence between the two groups had differences (11.1% vs. 50.0%, P=0.023) although the cumulative recurrence-free survival between the two groups had no differences (P=0.7808). There was a significant difference in the overall survival (P=0.0407). The 1-year and 3-year cumulative overall survival rate was 87.5% and 73.3%, 52.2% and 20.4% in group I and group II, respectively. CONCLUSIONS IRFAPA is an effective and safe procedure for unresectable HCC. IRFAPA is preferred to PRFA therapy if the patients' conditions can tolerate laparotomy.

Abstract
Selenium (Se) is an essential trace element for animals. Selenocysteine (Sec), the 21st aminoacid, is a component of selenoproteins and has been founded in the active center of selenoenzymes. The functions of Se within the body have been primarily shown in the forms of selenoproteins, especially selenoenzymes. Incorporation of selenocysteine occurs on the basis of genetic expression and Se is the only trace element under direct genetic control. Recently, findings have shown that Se and selenocompounds conducted many other potential functions such as protection against inflammatory factors, inhibition of protein kinase C (PKC), stimulation of MAP kinase (mitogen activated protein kinase/myelin basic protein kinase) and S6 kinase (ribosomal S6 protein kinase), regulation of the immune system and interaction with other elements and vitamins etc, suggesting that the roles of Se in human health may be more diverse than previously suspected.
