Objective: To explore the clinical efficacy and toxic and side effects of recombinant human endostatin (rhendostatin/endostar) combined with chemotherapy in the treatment of advanced gastric cancer. Materials and Methods: A total of 70 patients with advanced gastrointestinal adenocarcioma confirmed by histopathology and/or cytological examination were divided into group A (37 patients) and group B (33 patients). Patients in group A were given intravenous drip of 15 mg endostar added into 500 mL normal saline, once every other day until the cessation of chemotherapy or patients' maximal tolerance to chemotherapy. Patients in group B received chemotherapy alone. Two groups selected the same chemotherapy regimens. FOLFIRI scheme: 90-min intravenous drip of $180mg/m^2$ irinotecan, intravenous drip of $200mg/m^2$ calcium folinate (CF) and $400mg/m^2$ 5-fluorouracil (5-Fu) on d1, and continuous intravenous pumping of 2 $400mg/m^2$ 5-Fu for 46 h. FOLFOX4 scheme: intravenous injection of $85mg/m^2$ oxaliplatin (L-OHP), $200mg/m^2$ calcium folinate (CF) and $400mg/m^2$ 5-FU on d1 for 2 h, and then continuous intravenous pumping of 2 $400mg/m^2$ 5-Fu for 46 h. XELOX scheme: oral administration of 1 $500mg/m^2$ xeloda (or tegafur 50~60 mg) in twice during d1~14 and intravenous drip of $135mg/m^2$ L-OHP on d1 for 2 h. The modified FOLFOX scheme: intravenous injection of $135mg/m^2$ L-OHP on d1 for 2 h, $200mg/m^2$ CF and 1.0 g tegafur during d1~5. Whereas, control Group B received chemotherapy regimens which were same as Group A, but no addition of endostar. Before chemotherapy, patients were given intravenous injection of 8 mg ondansetron, intramuscular injection of 10 mg metoclopramide and 20 mg diphenhydramine for prevention of vomiting, protection of liver and stomach as well as symptomatic supportive treatment. One cycle was 21 d, 4~6 cycles in total. The efficacy was evaluated every 2 cycles. Results: 32 patients in Group A could be evaluated, and the response rate (RR) and disease control rate (DCR) were 59.38% and 78.13%, respectively. 31 patients in Groups could be evaluated, and the RR and DCR were 32.26% and 54.84%, respectively. The differences between 2 groups were significant. The toxic effects include myelosuppression, gastrointestinal reaction, fatigue, cardiotoxicity and peripheral neurotoxicity. Conclusions: Preliminary observations show that endostar (once every other day) combined with chemotherapy is effective in the treatment of advanced gastrointestinal cancer, with low toxic effects, good tolerance, deserving further study.

Cyclic AMP responsive element binding protein 3-like 4 (CREB3L4) has been reported as a transcription factor showing high expression in various cancers, whereas the mechanism of CREB3L4 in lung adenocarcinoma (LUAD) progression remains unclear yet. Expression levels of CREB3L4 and its downstream target gene AarF Domain Containing Kinase 5 (ADCK5) in LUAD tissues were analyzed by bioinformatics methods and were detected by real-time quantitative polymerase chain reaction at cellular level. The signaling pathways in which the downregulated ADCK5 enriched were analyzed via Gene Set Enrichment Analysis. The regulatory relationship between CREB3L4 and ADCK5 was identified by ChIP and dual luciferase reporter assay. CCK-8 and colony formation assays were utilized to evaluate LUAD cell proliferation. Transwell was utilized to measure migration and invasion of LUAD cells. Western blot was employed to check expression changes of CREB3L4, ADCK5, TGFβ pathway proteins and Epithelial- Mesenchymal Transition related proteins. Compared with paracancer tissues, CREB3L4 and ADCK5 were highly expressed in LUAD tissues, while silencing CREB3L4 could dramatically hinder invasion, proliferation and migration of LUAD cells. ADCK5 was the downstream target gene of CREB3L4, and CREB3L4 promoted the transcription of ADCK5. ADCK5 was markedly enriched in the TGFβ pathway, which stimulated the malignant development of LUAD cells by activating this pathway. In addition, the rescue assay verified that CREB3L4 regulated the TGFβ pathway by activating ADCK5, thereby accelerating LUAD cell malignant phenotypes. This study revealed the mechanism of CREB3L4/ADCK5 axis facilitating malignant phenotypes of LUAD cells, and bred new insights into the LUAD treatment.

A strain of phosphate solubilizing bacterium was isolated from rhizosphere and identified as Burkholderia sp. by 16S-rRNA gene sequence analyses. The bacterium was found to release gluconic acid and the solubilization of hydroxyapatite in the liquid medium by a significant drop in pH to 3.7 from an initial pH 7.0. The soluble-P concentration continuously increased during the incubation periods and the total amount of soluble P released in culture filtrate was detected at 990 mg $L^{-1}$ after 10 days of inoculation. Most promoted maize growth was found in the standard NPK (240-120-120 kg $ha^{-1}$) soil inoculation with Burkholderia sp. (Twenty milliliters/plant, 106 CFU) and also in the absence of Burkholderia sp. inoculation, the soil amended with only 2/3 levels of P gave significant higher plant yield compared to 1/3 levels of P or without P supplementation.

Background: To study the effect of parecoxib, a novel cyclooxygenase-2 selective inhibitor, on the radiation response of colorectal cancer (CRC) cells and its underlying mechanisms. Materials and Methods: Both in vitro colony formation and apoptosis assays as well as in vivo mouse xenograft experiments were used to explore the radiosensitizing effects of parecoxib in human HCT116 and HT29 CRC cells. Results: Parecoxib sensitized CRC cells to radiation in vitro with a sensitivity enhancement ratio of 1.32 for HCT116 cells and 1.15 for HT29 cells at a surviving fraction of 0.37. This effect was partially attributable to enhanced apoptosis induction by parecoxib combined with radiation, as illustrated using an in vitro apoptosis assays. Parecoxib augmented the tumor response of HCT116 xenografts to radiation, achieving growth delay more than 20 days and an enhancement factor of 1.53. In accordance with the in vitro results, parecoxib combined with radiation resulted in less proliferation and more apoptosis in tumors than radiation alone. Radiation monotherapy decreased microvessel density (MVD) and microvessel intensity (MVI), but increased the hypoxia level in xenografts. Parecoxib did not affect MVD, but it increased MVI and attenuated hypoxia. Conclusions: Parecoxib can effectively enhance radiation sensitivity in CRC cells through direct effects on tumor cells and indirect effects on tumor vasculature.

The purpose of this study was to explore the relationship between life style and metabolic syndrome. The cross-sectional survey was conducted in Pingliang community in Shanghai in Jan 2003. The data was collected by questionnaire, and the results were analyzed by SPSS. It was found that the prevalence of Metabolic Syndrome (MS) was $13.4\%$ in the community, and the body mass index (BMI), waist-to-hip ratio (WHR), systolic blood pressure (SBP), diastolic blood pressure (DBP), serum triglyceride (TG), total cholesterol(TC), low density lipoprotein-cholesterol (LDL-C), and fast plasma glucose (FPG) in MS group were higher than that in non-MS group. Logistic regression analysis indicated that BMI and WHR were positively correlated to the prevalence of MS, and physical activity was negatively correlated to the prevalence of MS. People with higher education levels (${\geq}10y$) had lower BMI, SBP, DBP, LDL-C and FPG. The prevalence of MS in the higher education level group was significantly lower than that of the lower education level group. These results suggested that BMI, WHR and physical activity were important factors of MS, and education background played an important role in the occurrence of MS. Therefore, it is very important to build a healthy life style for preventing and controlling the incidence and developing of MS.

Li, Lu-Ning,Jiang, Kai-Tong,Tan, Peng,Wang, Ai-Hua,Kong, Qing-Yin,Wang, Cui-Yue,Lu, Hua-Rong,Wang, Jing Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.9

The chemokine receptor 4 (CXCR4) has been widely used in diagnosis and prognosis of colorectal cancer (CRC). However, there is no current consensus on the impact of CXCR4 on CRC patients. The purpose of this study was to evaluate the prognostic and clinicopathological importance of CXCR4 in CRC patients. Databases, such as PubMed, Cochrane library, CBM and EMBASE updated to 2014 were searched to include eligible articles. We analysed correlations between CXCR4 expression and clinicopathological features and overall survival (OS). A total of 1, 055 CRC patients from twelve studies were included in the study. The pooled odds ratios (ORs) which indicated CXCR4 expression was likely to be associated with TNM stage (OR=0.43, CI=0.34-0.55, P<0.00001), lymph node status (OR=2.23, CI=1.23-4.05, P=0.008) and vascular invasion (OR=2.21, CI=1.11-4.39, P=0.02). Poor overall survival of CRC cancer was found to be significantly related to CXCR4 overexpression (hazard ratio (HR) 1.36 CI=1.17-1.59, P<0.0001), whereas combined ORs revealed that CXCR4 expression had no correlation with gender or differentiation. Based on the published studies, CXCR4 overexpression in patients w ith CRC indicates poor survival outcome and clinicopathological factors.
