Changes in Large Livestock Breeding Industry and Their Influences on Gross Output Value of Animal Husbandry in Guyuan City of Ningxia

[Objectives]The aim of this paper was to reveal the changes of large livestock industry and their influence on animal husbandry economy in Guyuan City of Ningxia.[Methods]The linear trend method was employed to quantify the change trends of the indicators for large livestock industry,and the ridge regression model was conducted to analyze their impacts on the gross output value of animal husbandry(GOVAH).[Results]The numbers of sold and slaughtered cattle and sheep in Guyuan presented a significant upward trend,while the number for hog had a significant downward trend,during 2000-2019.The GOVAH in Guyuan and its 5 counties had increased by 2-3 times in recent 20 years,which was mainly driven by large-scale livestock breeding.The cattle and sheep breeding sectors had positive effects on GOVAH,while the hog breeding sector had negative effect.[Conclusions]This study provides a reference for the structural adjustment and large-scale development of animal husbandry.

肿瘤患者静脉血栓栓塞抗凝出血与复发风险研究进展

肿瘤相关静脉血栓栓塞症(cancer-associated venous thromboembolism,CAVTE)为肿瘤患者在疾病进程中的常见并发症和死亡原因。其静脉血栓栓塞症(venous thromboembolism,VTE)复发和抗凝后严重出血的高风险可能会导致治疗延误和死亡率增加。目前,国内外指南并未推荐对所有门诊患者直接进行一级预防,但建议在化疗前评估发生静脉血栓栓塞的个体风险。本文对目前肿瘤患者静脉血栓栓塞抗凝出血与复发研究进展以及现行VTE防治指南和VTE风险评估模型进行综述。
