动物卫生监督执法与刑事司法衔接实践分析

行政执法与刑事司法,都承载着维护社会秩序,保障公民、法人或者其他组织的合法权益的重要功能。2018年7月,甘肃省金塔县兽医行政管理部门检测发现,养殖户杨某涉嫌经营染疫动物。经立案调查,认定当事人违法事实存在,其行为违犯了《动物防疫法》《刑法》的有关规定,随即移交公安机关追究刑事责任,经法院判决,当事人杨某销售不符合安全标准的食品罪,依法给予了惩处。这提示官方兽医应熟知法律法规,准确把握食品安全的犯罪界限,严格审查移送案件证据,正确履行职责,实现打击违法犯罪和保护公民权利的有效平衡。

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.     

不同保鲜膜对草莓果实贮藏品质的影响

以草莓"红颜"为试材,以PVC(聚氯乙烯)膜为对照,研究了PE(聚乙烯)膜、PHM(多层PE系)膜、纳米银膜、PVDC(聚偏二氯乙烯)膜等5种保鲜处理在(4.0±0.6)℃贮藏条件下对草莓果实失重率、硬度和可溶性固形物、维生素C、可溶性糖含量及感官品质的影响。结果表明:相较于PVC保鲜膜,PVDC膜与PHM膜能够较好的保持草莓果实的贮藏品质。其中PVDC膜包装可以有效地减少果实水分散失,保持草莓的硬度以及果实可溶性固形物含量;PHM膜包装可以较好的保持草莓果实可溶性固形物、维生素C、可溶性糖含量,维持果实的营养成分。

磷供应水平对盆花月季'仙境'生长和品质的影响

以盆花月季'仙境'为试材,采用根部浇灌方式,设置0(P0)、10 (P10)、20(P20)、30(P30)g·柱-14个磷供应水平,研究了磷水平对盆花月季'仙境'根系生长、不同器官氮磷养分吸收、叶片SPAD值以及开花品质(花朵数量、花径、花朵干质量等)的影响,以期为月季养分管理提供参考依据.结果 表明:磷不同供应水平明显改变了'仙境'的根系形态,P20和P30处理较P0和P10处理,总根长增加了81％～111％,总根表面积扩大了133％～196％,细根总长度增加了95％～119％.植株不同器官(新生叶片、新生枝条和根系)生物量和氮、磷养分积累量表现出与根系生长类似的趋势.与P0和P10处理相比,P20和P30处理单株花朵数量增加128％～206％,叶片SPAD值增加16％～21％.与对照P0相比,P10、P20和P30花径分别增加12％、19％和24％.植株总根长与总氮和总磷吸收量表现出显著的正相关关系.综上所述,盆花月季'仙境'对不同磷供应水平表现出高度的根形态可塑性,适宜的磷供应水平促进根系生长和养分吸收,提高开花数量和品质.
