BACKGROUND Radical D2 lymphadenectomy for advanced gastric cancer as a standard procedure has gained global consensus. Mounting studies have shown that the number of lymph nodes dissection directly affects the prognosis and recurrence of gastric cancer. Our previous study showed that there was no obvious lymph node around the abnormal hepatic artery derived from the superior mesenteric artery. AIM To investigate the relationship between celiac artery variation and the number of lymph nodes dissection in gastric cancer surgery. METHODS The clinicopathological data of 421 patients treated with radical D2 lymphadenectomy were analyzed retrospectively. The difference of the number of lymph nodes dissection between the celiac artery variation group and the normal vessels group and the relationship with prognosis were analyzed. RESULTS Celiac artery variation was found in 110 patients, with a variation rate of 26.13%. Celiac artery variation, tumor staging, and Borrmann typing were factors that affected lymph node clearance in gastric cancer, and the number of lymph nodes dissection in patients with celiac artery variation was significantly less than that of non-variant groups (P 0.05). Univariate and multiple Cox regression analysis showed that celiac artery variation was not a prognostic factor for gastric cancer (P > 0.05). Tumor staging, intraoperative bleeding, and positive lymph node ratio were prognostic factors for gastric cancer patients (all P < 0.05). CONCLUSION The number of lymph nodes dissection in patients with celiac artery variation was reduced, but there was no obvious effect on prognosis. Therefore, lymph nodes around the abnormal hepatic artery may not need to be dissected in radical D2 lymphadenectomy.

The attempt to obtain long-term observed data around some sea areas we concern is usually very hard or even impossible in practical offshore and ocean engineering situations. In this paper, by means of linear mean-square estimation method, a new way to extend short-term data to long-term ones is developed. The long-term data about concerning sea areas can be constructed via a series of long-term data obtained from neighbor oceanographic stations, through relevance analysis of different data series. It is effective to cover the insufficiency of time series prediction method＇s overdependence upon the length of data series, as well as the limitation of variable numbers adopted in multiple linear regression model. The storm surge data collected from three oceanographic stations located in Shandong Peninsula are taken as examples to analyze the number-selection effect of reference oceanographic stations（adjacent to the concerning sea area） and the correlation coefficients between sea sites which are selected for reference and for engineering projects construction respectively. By comparing the N-year return-period values which are calculated from observed raw data and processed data which are extended from finite data series by means of the linear mean-square estimation method, one can draw a conclusion that this method can give considerably good estimation in practical ocean engineering, in spite of different extreme value distributions about raw and processed data.

Dear Editor, Grain length （size） and weight are essential components of crop yield. To date, many QTLs/genes for these traits have been identified. GS3 encodes a putative transmembrane protein and functions as a negative regulator, and its larger-grain allele contains a nonsense mutation causing a 178-aa truncation （Fan et al., 2006）. GL3.1/qGL3 encodes a putative protein phosphatase and also acts as a negative regulator of grain size （Qi et al., 2012; Zhang et al., 2012）. Another negative regulator of grain size and weight is TGW6, which hydrolyzes indole-3-acetic acid （IAA）-glucose into IAA and glucose （Ishimaru et al., 2013）.

The ubiquitin system is crucial for the development and fitness of higher ***-etiolation, during which green plants initiate photomorphogenesis and establish autotrophy, is a dramatic and complicated process that is tightly regulated by a massive number of ubiquitylation/de-ubiquitylation events. Here we present site-specific quantitative proteomic data for the ubiquitylomes of de-etiolating seedling leaves of Zea mays L.(exposed to light for 1, 6, or 12 h)achieved through immunoprecipitation-based high-resolution mass spectrometry(MS). Through the integrated analysis of multiple ubiquitylomes, we identified and quantified 1926 unique ubiquitylation sites corresponding to 1053 proteins. We analyzed these sites and found five potential ubiquitylation motifs, KA, AXK, KXG, AK, and TK. Time-course studies revealed that the ubiquitylation levels of 214 sites corresponding to 173 proteins were highly correlated across two replicate MS experiments, and significant alterations in the ubiquitylation levels of 78 sites(fold change >1.5) were detected after de-etiolation for 12 h. The majority of the ubiquitylated sites we identified corresponded to substrates involved in protein and DNA metabolism, such as ribosomes and ***, multiple ubiquitylation sites were detected in proteins whose functions reflect the major physiological changes that occur during plant de-etiolation, such as hormone synthesis/signaling proteins, key C4 photosynthetic enzymes, and light signaling proteins. This study on the ubiquitylome of the maize seedling leaf is the first attempt ever to study the ubiquitylome of a C4 plant and provides the proteomic basis for elucidating the role of ubiquitylation during plant de-etiolation.

作者： Xianjue Wang Changjin Ao Khas-Erdene Shuaiwang Liu chen bai Fuquan Zhang Ying Zhang Peng Gao College of Animal Science Inner Mongolia Agricultural University

This experiment was conducted to investigate the effects of infusing milk precursors into the external pudic artery on rumen fermentation in lactating dairy cows. Eight multiparous Holstein cows were randomly assigned to Group A(experimental group) and Group B(control group) with 4 cows each. A2×4 complex factor crossover design was used. Cows in Group A were fed corn straw as the only roughage, and cows in Group B were fed mixed roughage. The experiment was divided into two *** the first period, cows in Group A, received treatments: 1) a basal infusate as a control(CSC); 2) a milk fat precursor infusion including C16:0, C18:0, C18:1 c9, C18:2 c6, C18:3 n3, acetic acid(CSF); 3) a milk protein precursor infusion including 16 amino acids(CSA); 4) the mixed infusion of milk fat and protein precursors(CSFA). And meanwhile, cows in Group B were infused the basal infusate as a control group. In the second period, the cows in both Groups A and B were crossed over, which cows in Group A were named as Group B and the cows originally in Group B were in Group A. The experimental results showed that cows in experimental group had higher ruminal pH compared with the control, and ruminal pH in CSC, CSF, CSA were significantly higher than those in their respective control group(P < 0.05). The concentration of ammonia nitrogen(NH_3-N) was significantly higher in CSA and CSFA compared with Group B(P < 0.05). We also observed that the infusion of mixed amino acids significantly increased the bacterial protein(BCP) content in rumen(P < 0.05) and influenced the rumen acetic acid concentration as well as the acetic to propionic ratio(P < 0.05). Milk fat precursors infusion significantly affected butyric acid concentration(P < 0.05). In addition, the content of lipopolysaccharide(LPS) in CSA was significantly higher than that in the control group(P < 0.05). It is concluded that the milk precursors infused into external pudic artery caused feedback effects on ruminal fermentation u
