在渔业方面，贯彻落实“一带一路”倡议，实施渔业“走出去，引进来”战略，促进我国水产养殖业和周边国家地区的交流合作，共同推动区域传统渔业向现代渔业转型升级，是现代渔业发展的必然方向。泰国作为“一带一路”之东盟国家，从泰国的渔业资源现状、渔业产业发展、渔业现阶段存在的优势和不足以及中泰渔业协作发展探索等多个方面进行阐述，通过研究泰国渔业现状及探索中泰渔业协作发展之路，提出技术支撑、资源引进、取长补短、共同进步等相对应的策略与建议，为中国-东盟国家在基于“一带一路”倡议的渔业层面战略发展提供样本。      

群井开采对毛乌素沙地地下水位的影响——以榆林市榆阳区昌汗敖包村土地开发项目为例

为探究毛乌素沙地大规模现代化高标准农田地下水开采对地下水位的影响，以榆林市榆阳区昌汗敖包村土地开发项目地下水监测网覆盖区作为研究区，选取分布于研究区的8眼机井进行了为期1年的地下水位埋深动态特征监测。结果表明:在灌溉期间，地下水位埋深呈先减小后增大的趋势；灌溉结束至进入下个灌溉周期之前，地下水位埋深逐渐增大至正常值。因此群井开采并未对项目区地下水位造成实质影响。      

夏季养猪企业关切的繁殖问题调查

当前养猪业进入困难时期，企业运营成本高企。炎热的夏季，种猪繁殖问题较为突出，再加上非洲猪瘟直接或者间接的原因，行业内母猪整体繁殖水平低下。团队近期对53家不同区域、不同规模、不同生产模式的养猪企业进行了调研，发现公猪问题、后备猪问题和哺乳期管理是当前猪场最为关心的3个问题。     

橡胶园酸性、中性土壤交换性钙、镁测定方法研究

为了获得简单、易操作、准确度高的橡胶园酸性、中性土壤交换性钙、镁测定方法,本试验通过响应面优化试验,建立称样量、提取液体积、提取方式与交换性钙测定结果之间的数学模型。结果表明：在25℃条件下,以1 mol/L的乙酸铵为土壤浸提液,称样量为2 g、提取液体积175 mL、振荡36 min,为橡胶园酸性、中性土壤的最佳提取条件。将上述条件下得到的结果与标准方法条件下得到的结果相对比,两结果的相对误差在1.25~3.04之间,均属合理范围。利用标准样品对优化方法进行试验验证,结果与推荐值相符。改进后的方法分析成本低、操作简便、测定结果准确、稳定性好,可用于橡胶园酸性、中性土壤交换性钙、镁的测定。

Differential regulation on C5 expression in goose versus mammals by glucose/palmitate provides a potential protection for goose fatty liver

Goose fatty liver is a specific type of nonalcoholic fatty liver that is protected from harmful effects associated with severe steatosis. Our previous findings suggest that suppression of the complement C5 may be relevant, but the mechanism is unclear. Therefore, in this study, we first verified the expression pattern of complement genes (including C5) during goose fatty liver formation and then determined the liver fat content and fatty acid composition by high-performance liquid chromatography (HPLC), followed by selecting the differential metabolites to treat HepG2, goose and mouse primary hepatocytes, aiming to explore the mechanism of C5 and inflammation suppression in goose fatty liver. The data confirmed the suppression of complement genes (including C5) in goose fatty livers. Moreover, fat content was significantly higher in fatty liver versus normal ones, with oleic acid and palmitic acid dominantly accounting for the difference. In line with this, high concentration of palmitate led to down regulation of C5 expression in goose primary hepatocytes whereas upregulation in mouse primary hepatocytes and HepG2 cells. In conclusion, regulation on C5 expression by fatty liver related factors including high level of palmitic acid may contribute to the protection of goose liver from severe hepatic steatosis.     

Spatio-temporal pattern evolution and spatial spillover effect of green development efficiency: Evidence from Shandong Province,China

Improving green development efficiency is urgently required, yet challenging, since it comprehensively reflects the bidirectional evolutionary relationship between regional development and resource and environmental consumption. The issue of regional green development efficiency has become a key topic; however, where the increase in efficiency originates and its spatial spillover effect remains unclear to date. Therefore, the spatial spillover effect of the green development efficiency of Shandong Province was quantified through the slack variable (SBM)-Undesirable and Spatial Durbin model. The green development efficiency showed clear spatial differentiation in Shandong Province. This was more obvious than the polarized development trend of the provincial capital circle that has Jinan at its core and the eastern coastal region with Qingdao at its core. Green development efficiency has a significant spatial spillover effect. The regression coefficient of the direct effect of the economic development level is positive. The regression coefficient of the indirect effect of the marketization level and government financial support level is negative. Science and technology played a positive role in the promotion of the green development efficiency of local and neighboring cities. This study contributes empirical evidence to the green development efficiency associated with regional development and resource and environment consumption of Shandong Province.

围场县马铃薯中典型药物污染特征及健康风险评价

为掌握典型药物在农作物中的污染特征及健康风险,保障农产品质量安全,利用超声萃取-固相萃取-高效液相色谱/串联质谱(LC-MS/MS)技术,对围场县全县马铃薯中5大类(磺胺类、四环素类、氟喹诺酮类、大环内酯类及其他类)25种药物污染水平及富集效果进行了调查,并对健康风险进行了评价。结果表明,有20种目标物被检出,不同目标物检出率差异显著,检出含量范围为0.13～3.67μg·kg-1,单种污染物最高检出含量为17.0μg·kg-1。马铃薯对目标污染物的富集系数范围在0.01～39.6之间,最大富集系数为61.8。畜禽粪便是马铃薯中药物残留的主要来源,尽管整体检出水平和健康风险相对较低,但长期摄入与协同作用引发的潜在健康风险不容忽视。因此,仍需严控污染源头,推进畜禽粪便安全资源化利用,确保农田环境质量及农产品安全品质。
