Background: The role of surgical resection for patients with single large (${\geq}5cm$) and/or multinodular (${\geq}2$) hepatocellular carcinoma (HCC) is still controversial. This systematic review was performed to evaluate the safety and efficacy of resection for patients with single large and/or multinodular HCC. Materials and Methods: Databases (the PubMed, Web of Science, Embase, and Cochrane databases) were systematically searched to identify relevant studies exploring the safety and efficacy of resection for single large and/or multinodular HCC, published between January 2000 and December 2014. Perioperative morbidity and mortality, overall survival, and disease-free survival of the resection group were calculated. In addition, these outcome variables were also calculated for the control group in the included studies. Results: One randomized controlled trial and 42 nonrandomized studies involving 9,580 patients were eligible for analysis. Eight (1,594 patients) of the 43 studies also reported the outcomes of transarterial chemoembolization (TACE). Although 51.4% of patients featured cirrhosis, 90.7% of them demonstrated Child-Pugh A liver function in the resection group. The median rates of morbidity (24.5%) and mortality (2.5%) after resection were significantly higher than that of TACE (11.0%, P<0.001; 1.9%, P<0.001). However, patients who underwent resection had significantly higher median one-, three-, and five-year overall survival (76.1%, 51.7%, and 37.4%) than those who underwent TACE (68.3%, 31.5%, and 17.5%, all P<0.001). The median 1-, 3-, and 5-year DFS rates after resection were 58.3%, 34.6%, and 24.0%, respectively. Conclusions: Although tumor recurrence after resection for patients with single large and/ or multinodular HCC continues to be a major problem, resection should be considered as a strategy to achieve long-term survival.
Role of B-doping in g-C3N4 nanosheets for enhanced photocatalytic NO removal and H2 generation

The photocatalytic application of graphic carbon nitrate (g-C3N4) was limited due to the shortcomings offew exposed active sites and serious recombination rate of photo-generated carrier. In this paper, Bdopedg-C3N4 nanosheets were synthesized by a two-step thermal polymerization method. AspreparedB-doped g-C3N4 nanosheets maintained the initial structure of g-C3N4. The composition analysisresults indicated the successful introduction of B element into the g-C3N4 structure. Under visible lightirradiation, as-prepared B-doped g-C3N4 nanosheets revealed excellent NO removal and hydrogen productionperformance, reaching 54% and 1639.29 lmol/g/h, respectively. The superior photocatalytic performancewas attributed to the ultrathin nanosheets obtained by thermal exfoliation, which have higherspecific surface area and more active sites. The introduction of B enhanced the charge migration and inhibitsthe recombination of photogenerated carriers. The cyclic experiment indicated that the sampleexhibited high stability. Enhanced photocatalytic mechanism from B doping was discussed.

Prostate cancer (PCa) is one of the most common malignant tumors, with a high rate of metastasis and recurrence. Circular RNA_0001165 (circ_0001165) has been shown to be involved in the advance of PCa. However, the interaction between circ_0001165 and microRNA in PCa has not been studied. Quantitative real-time polymerase chain reaction was used to detect the expression of related genes in PCa tissues and cells. The expression of related epithelial-mesenchymal transition proteins was detected by Western blotting. The interaction of miR-654-3p with circ_0001165 or dimethylarginine dimethylaminohydrolase 1 (DDAH1) has been notarized by Dual-luciferase reporter assay and RNA immunoprecipitation assay. Xenotransplantation experiments confirmed the function of circ_0001165 in vivo. Circ_0001165 and DDAH1 are significantly highexpressed in PCa tissues and cells. Silencing circ_0001165 can reduce the proliferation, migration, invasion and tube formation of LNCaP and DU145 cells. MiR-654-3p is a target of circ_0001165. Silencing circ_0001165 can inhibit the malignant behavior of PCa cells by releasing miR-654- 3p. In addition, DDAH1 is a target of miR-654-3p. Overexpression of DDAH1 partially restored the inhibitory effect of miR-654-3p on cell proliferation. Animal experiments confirmed the anti-tumor effect of silence circ_0001165 in vivo. Circ_0001165 regulates the expression of DDAH1 by regulating miR-654-3p, thereby mediating the process of PCa, and at least partially promoting the development of PCa cells, providing a novel targeted therapy for PCa.

It is reported that sinomenine (SIN) and 5-fluorouracil (5-FU) both are effective for colon cancer, but their cooperative suppressive effects and toxicity remain to be clarified in detail. This study aimed to determine suppressive effects and toxicity of sinomenine (SIN) plus 5-fluorouracil (5-FU) on LoVo colon carcinoma cells in vitro and in vivo. CCK-8, Hoechst 33258 staining and an annexin V-FITC/PI apoptosis kit were used to detect suppressive effects. Western blotting was applied to investigate the essential mechanism underlying SIN and 5-FU-induced apoptosis. SIN or 5-FU or both were injected into nude mice, and then suppressive effects and side effects were observed. SIN plus 5-FU apparently inhibited the proliferation of LoVo cells and induced apoptosis. Moreover the united effects were stronger than individually (p<0.05). The results of annexin V-FITC/PI staining and Hoechst 33258 staining showed that the percentage of apoptotic cells induced by SIN and 5-FU combined or alone was significantly higher than the control group (p<0.05). Expression of Bax and Bcl-2 was up-regulated and down-regulated respectively. SIN or 5-FU significantly inhibited effects on the volume of tumour xenografts and their combined suppressive effects were stronger (p<0.05). No obvious side effects were observed. It was apparent that the united effects of SIN and 5-FU on the growth of colorectal carcinoma LoVo cells in vitro and in vivo were superior to those using them individually, and it did not markedly increase the side effects of chemotherapy.

Purpose: To study the expression of angiogenin-2 (Ang-2) and its receptor Tie-2 in colorectal cancer and discuss the possible mechanisms behind this process. Materials and Methods: Using the streptavidin-peroxidase (SP) immunohistochemical method, paraffin sections from 100 colorectal cancer samples and 10 samples from tumor-adjacent normal tissue (> 2 cm from the edge of the gross tumor) were tested for protein expression of Ang-2, Tie-2, PI3K, and AKT. Reverse transcription-polymerase chain reaction and Western blots were further used to measure expression of the 4 genes and proteins in 20 freshly-resected colorectal cancer samples and tumor-adjacent normal tissues. Results: In colorectal cancer tissues, the expression of the Ang-2, Tie-2, PI3K, and AKT genes and their proteins was significantly higher than in tumor-adjacent normal tissues. Protein expression in poorly-differentiated adenocarcinoma was higher than that in well and moderately differentiated adenocarcinoma. According to Duke's classification, the protein expression in Stages C and D was significantly higher than that in Stages A and B. In the group with lymphatic metastasis, the protein expression was higher than that without lymphatic metastasis. Conclusions: In colorectal cancer, the expression of the Ang-2, Tie-2, PI3K, and AKT genes and their proteins is markedly higher than those in tumor-adjacent normal tissues. No correlation was observed between protein expression and gender, location, or histologic type. Correlations did exist between protein expression and differentiation level, stage of Duke's classification, and lymphatic metastasis; in colorectal cancer tissues with lower differentiation levels, higher stages of Duke's classification, and lymphatic metastasis, the expression of all 4 proteins was higher. The study of their expression patterns and relationships with aggression and metastasis will provide a valuable experimental foundation for assessing prognosis and targeted therapy of colorectal cancer.

In this study we present a mammalian cell culture model that allows to study the effect of endocrine disruptors (EDCs) on aromatase activity of aquatic amphibian, Bombina orientalis. Bombina orientalis aromatase gene was subcloned into a mammalian expression vector and subsequently transfected to mammalian cells. Although the protein expression level of Bombina orientalis aromatase was low, it had a significant aromatase activity. When EDCs were added to aromatase transfected cells, aromatase activity was significantly decreased. We report here that this system may be used to monitor the effect of EDCs on aromatase activity of aquatic organisms.
