【问题】农业水价综合改革是推进节约增效型农业、保障国家水安全的关键改革。但地方政策实践中面临农户节水意识与用水方式尚未完全改善、政府部门水价形成机制和节水激励机制尚未良性运行、农业节水的经济和社会效应尚未充分彰显等系... 【问题】农业水价综合改革是推进节约增效型农业、保障国家水安全的关键改革。但地方政策实践中面临农户节水意识与用水方式尚未完全改善、政府部门水价形成机制和节水激励机制尚未良性运行、农业节水的经济和社会效应尚未充分彰显等系列问题,政策实际绩效与目标绩效间产生偏差。政策绩效偏差何以形成?关键影响因素及其内在关联是什么?如何矫正绩效偏差并增进政策绩效?【方法】以甘肃省10个试点县(区)农业水价综合改革为研究样本,对实地调研和深入访谈所获取的数据资料进行质性编码,建构我国农业水价综合改革政策绩效偏差的归因模型。【发现】农业水价综合改革政策绩效偏差的形成是涉及“利益相关者—政策执行—政策情境”交叠驱动的复杂过程,表现在:1.在主体层面,利益相关者政策认知、偏好和协同行动是决定政策绩效的关键因素;2.在行动层面,任务分解层层加码、政策落实困难是构成导致政策绩效偏差的核心变量;3.在场域层面,政策资源和改革需求等情境要素进一步催化了政策绩效偏差的形成。【贡献】相对于源自政府绩效管理工具性路径下对绩效悖论和绩效损失的关注,本研究的贯穿概念:绩效偏差,则可覆盖公共政策全过程,有更为广阔的研究价值与适用场域。本研究构建了基于农业水价综合改革政策绩效偏差的影响因素及相互间逻辑关联的理论模型,为解释公共政策绩效偏差提供新的视角;并从整合政策利益相关者认知与偏好、加强政策执行效能和优化政策环境三个维度提出农业水价综合改革政策矫正策略,为地方政府提升政策整体绩效提供参考。 展开更多

The high incidence,mortality,and disability associated with ischemic stroke pose a significant threat to human health.The intestinal microbiota significantly influences the onset,progression,and prognosis of ischemic stroke.Gut flora plays a pivotal role in brain-gut interactions.The reflection of changes in the gut and brain caused by gut microbes faciltates the investigation of early warning biomarkers and potential therapeutic targets for ischemic stroke.In this narrative review of the relationship between gut microbiota and ischemic stroke,we primarily discuss three topics,grounded in real-world human and animal studies.First,we examined the relationship between ischemic stroke and intestinal microbiota and its metabolites,delineate the overall characteristics of intestinal microbiota dysregulation in ischemic stroke,and assess the potential clinical value,prevailing research controversies,and unique phenomena of intestinal microbiota metabolites such as trimethylamine N-oxide and short-chain fatty acids in ischemic stroke.Second,we explored the potential communication pathways between intestinal flora and ischemic stroke based on the brain-gut axis,encompassing metabolic pathways,immune pathways,and neural pathways.Finally,we encapsulated the factors influencing the severity of ischemic stroke via intestinal flora,the pharmacological and nonpharmacological interventions that modulate intestinal flora in treating ischemic stroke,and the current research landscape of intestinal flora in the context of ischemic stroke sequelae. 展开更多

目的总结椎-基底动脉夹层动脉瘤(VBDA)介入栓塞治疗的效果。方法回顾性分析2014年4月至2018年4月厦门大学附属中山医院收治的37例VBDA患者(32枚VBDA病灶)的临床资料,包括一般资料、动脉瘤特征和围术期并发症发生情况等,记录患者出院时... 目的总结椎-基底动脉夹层动脉瘤(VBDA)介入栓塞治疗的效果。方法回顾性分析2014年4月至2018年4月厦门大学附属中山医院收治的37例VBDA患者(32枚VBDA病灶)的临床资料,包括一般资料、动脉瘤特征和围术期并发症发生情况等,记录患者出院时及随访6个月时的临床预后,采用改良Rankin量表(mRS)评价患者术后预后情况。结果37例患者中男性24例,女性13例,年龄为54(24~78)岁。接受介入治疗29例,拒绝手术8例。32枚VBDA病灶中25枚接受支架辅助弹簧圈栓塞治疗,3枚行单纯弹簧圈栓塞治疗,4枚行动脉瘤及载瘤动脉闭塞术。所有患者均在早期行介入治疗(<72 h)。术后随访过程中共有4枚出现复发,再次行介入治疗,其余均保持稳定。椎动脉夹层动脉瘤随访中预后极好13例,好3例,差1例,死亡0例;基底动脉夹层动脉瘤随访中预后极好7例,好2例,差3例,死亡0例。椎动脉夹层动脉瘤入院时Hunt-Hess分级越低者预后越好(H=7.566,P=0.006),基底动脉夹层动脉瘤入院时Hunt-Hess分级、世界神经外科联盟(WFNS)分级越低者预后越好(H=5.666,P=0.017)。另外,VBDA患者入院时Hunt-Hess分级为0~Ⅲ级组预后极好的比例明显高于Ⅳ~Ⅴ组,比例分别为90.0%vs 22.2%,P=0.001。结论VBDA的介入治疗是安全有效的,可降低术后再出血风险,没有明显的手术并发症,并有良好的随访结果,且术前较低的Hunt-Hess分级能获得良好的临床结果。另外,早期栓塞不影响临床结果,但降低了再出血的风险。 展开更多

Background:Spontaneous intracerebral hemorrhage(SICH)has high morbidity and mortality,with no clear standard of treatment available.Compared with the craniotomy approach,neuroendoscopy is a relatively minimally invasive treatment method,and may be an efficient alternative.Therefore,this meta-analysis aimed to assess the clinical efficacy of neuroendoscopy and craniotomy in SICH patients.Methods:The electronic databases Web of Science,PubMed,EmBase,MEDLINE,and the Cochrane Library were systematically searched.According to the PRISMA template,we finally selected and analyzed 14 eligible studies that evaluated neuroendoscopy versus craniotomy.Primary outcomes included operation time,intraoperative blood loss volume,evacuation rate,residual hematoma,complications,hospital stay duration,clinical outcomes,and other parameters.Results:A total of 4 randomized controlled trials(RCTs)and 10 retrospective studies(non-RCTs)involving 1652 patients were included in the final analysis.In the neuroendoscopy(NE)group,operation time(p<0.00001),intraoperative blood loss volume(p<0.0001),hematoma evacuation rate(p=0.0002),complications(p<0.00001),hospitalization days(p=0.004),and mortality(p<0.0001)were significantly different from those of the craniotomy(C)group,with a higher rate of good recovery compared with the craniotomy group(P<0.00001).Conclusions:These findings suggest that patients with SICH and physicians may benefit more from neuroendoscopic surgery than craniotomy. 展开更多
