Long-term changes (2003-14) of water temperature, DO, pH, TN, NH4-N, TP, and CODMn were examined at eight sampling stations along the Liujiang River. Water quality parameters showed considerable spatial and temporal variability. Annual averages of those parameters were 22.1ºC, 7.8 mg/L, 7.58, 1.35 mg/L, 0.27 mg/L, 0.06 mg/L, and 1.7 mg/L, respectively. An increasing trend for TN/TP and a decreasing trend for pH were observed in all parts of the Liujiang. Pollution levels were generally higher in the lower Liujiang than in the upper and middle parts of the river due to the impact of urban sewage. All indicators reached level III water quality standards except TN, which suggests that the control of nitrogen emissions should be strengthened. Relatively high N/P ratios in the Liujiang contribute to a potential for phosphorus limitation of phytoplankton. The average concentration of Chlorophyll-a was 1.2 μg/L in 2014. The TLI index indicated that the eutrophication state of the Liujiang was mesotrophic, while the downstream water was polluted due to its nutrient inputs from agriculture and urban sources. The water quality of the river keeps well by comparison to other major rivers of the world, which provided the basis for urban development and river protection in Liuzhou City.

Plant physiology and biochemistry are both affected by salinity, which is an important abiotic stressor. In this study, we identified transcript-derived fragments (TDFs) in response to salt stress in black locust (Robinia pseudoacacia L.) using cDNA-amplified fragment length polymorphism (cDNA-AFLP) analysis. Seventy-four TDFs were identified in the leaves of two-year-old plants after NaCl treatment (500 mM for 0, 5, 10 and 15 days). Based on the gene ontology (GO) terminology, 30 TDFs shared high homology with known genes and were classified into 6 groups: metabolism-related factors, defense-related proteins, transcription factors, stress and signal transductionrelated factors and energy-related factors. Eight TDFs were selected for further study, and their expression patterns in the leaves were verified by real-time polymerase chain reaction (RT-PCR) at different stages of salt stress. Our data provide a theoretical basis for research on the mechanisms of salt tolerance in woody plants.

STGC3 is a novel candidate tumor suppressor gene that was found to be associated with nasopharyngeal carcinoma (NPC) via the cDNA cloning and RACE processes. The biological function of the STGC3 protein and its expression level in nasopharyngeal carcinoma remain unknown. This study aimed to evaluate the STGC3 protein expression level in NPC and to investigate the inhibitory function of STGC3 as a candidate tumor suppressor gene. We assessed the expression of the STGC3 protein in NPC biopsies and normal control specimens via Western blot and immunohistochemical analysis. The expression of STGC3 as induced by doxycycline (Dox) via a tetracycline (Tet)-regulated system in human nasopharyngeal carcinoma cell line CNE2 was also established, and the effect of STGC3 restoration on the biological behavior of CNE2 was observed. A reduced level of STGC3 expression (0.978 ± 0.213 versus 0.324 ± 0.185, P < 0.05) was detected in NPC versus normal nasopharyngeal tissue by Western blot assay. Immunohistochemical assays for STGC3 detected positive staining in the nuclei and cytoplasm of epithelial cells, and the positive expression rate in NPC, 8 of 21 (38%), was lower than that in normal nasopharynx samples, 16 of 22 (72%). After STGC3 expression was restored, the growth capacity and clone formation potential of CNE2 cells in soft agar were significantly suppressed, and the cell percentage in G0/G1 phase increased, while the percentage of cells entering the S and G2 phases decreased. This indicates that an abnormality in STGC3 expression is associated with nasopharyngeal carcinogenesis and that it may play an important role in controlling cell growth and regulating the cell cycle.

The Hun River Basin is one of the most important heavy industrial and agricultural production bases of China. Its pollution level has exerted negative effects on human health. In order to investigate pollution levels and estimate the cancer risk of water in the river, water samples were collected in both the flood and dry periods. Pollution indicators were detected in terms of heavy metals, polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs). The mean concentrations of chromium (Cr), cadmium (Cd), PAHs, and PCBs were, respectively, 7.96 μg/L, 0.08 μg/L, 2597.22, and 21.21 ng/L in the flood period, and 19.02 μg/L, 1.10 μg/L, 1212.91, and 16.69 ng/L in the dry period. The concentrations of heavy metals were lower in the flood period than those in the dry period. However, in the meantime, contamination by PAHs and PCBs was heavier in the flood period than those in the dry period – the most abundant being fourring PAHs and three-Cl PCBs in the flood period, and three-ring PAHs, four-ring PAHs, and four-Cl PCBs in the dry period. The carcinogenic contribution rate was in the order: Cr> PAHs >PCBs >Cd. The mean lifetime value of carcinogenic risk was 8.200×10-4, which indicated that there was a risk of cancer associated with drinking Hun River water.
