BACKGROUND Previous studies have indicated bidirectional associations between urate levels and inflammatory bowel disease(IBD),including ulcerative colitis(UC)and Crohn’s disease(CD).However,it remains unclear whether the observations are causal because of confounding *** To investigate the causal associations between urate levels and IBD using bidirec-tional Mendelian randomization(MR).METHODS Independent genetic variants for urate levels and IBD were selected as instru-mental variables from published genome-wide association studies(GWASs).Summary statistics for instrument-outcome associations were retrieved from three separate databases for IBD(the UK Biobank,the FinnGen database and a large GWAS meta-analysis)and one for urate levels(a large GWAS meta-analysis).MR analyses included the inverse-variance-weighted method,weighted-median estimator,MR-Egger and sensitivity analyses(MR-PRESSO).A meta-analysis was also conducted to merge the data from separate outcome databases using a fixed-effects *** Genetically higher serum urate levels were strongly associated with an increased risk of UC[odds ratio(OR):1.95,95%confidence interval(CI):1.86-2.05]after outlier correction,and the ORs(95%CIs)for IBD and CD were 0.94(95%CI:0.86-1.03)and 0.91(95%CI:0.80-1.04),*** studies have confirmed the positive association between urate levels and ***,genetically predicted IBD was inversely related to urate levels(OR:0.97,95%CI:0.94-0.99).However,no association was observed between genetically influenced UC or CD and urate *** Urate levels might be risk factors for UC,whereas genetically predicted IBD was inversely associated with urate *** findings provide essential new insight for treating and preventing IBD.

中国共产党巡视制度在扬弃与继承中与时俱进地实现属性功能变迁。新民主主义革命时期,巡视制度是党组织领导权的延伸,指导整顿党组织建设,实现上传下达。社会主义革命和建设时期,巡视制度监督属性强化,指导下级党组织落实上级党组织具体任务,并成为干部监督的重要方式。改革开放和社会主义现代化建设新时期,巡视制度直指腐败问题,逐步成为党内法规认可的党内监督的重大举措,对下级党组织进行全方位监督。中国特色社会主义进入新时代,巡视制度成为反腐败的制度利器,政治巡视基本定位确立并不断深化,在党和国家监督体系构建中发挥纽带作用。百余年来,中国共产党巡视制度由领导制度的辅助安排发展为党内监督的战略性制度安排,其根本政治任务始终是维护党中央权威和集中统一领导。

“礼乐论化”是传统文化的核心思想,直接渗透和影响了戏曲教化观念的生成和发展。宋元时期,文人开始介入戏曲活动,他们自觉地将“诗教”观念移植进戏曲。高则诚提出“不关风化体,纵好也徒然”,奠定了“风教观”的基础,明中期剧坛掀起了教化剧风潮。随着教化剧的逐渐僵化,明后期在王阳明心学的影响下,以汤显祖为代表的一批剧作家提出了“以情为理”的教化观念。清代皇权强化,戏曲中“情”与“理”以调和的态势,逐渐融入审美性的教化观念,成为“戏教”思想的两个重要维度。

长江中游城市群是中国高质量发展的重要增长极,识别该区域不同经济发展梯度下国土空间格局演变的时空特征及驱动力,对于优化国土空间格局、推动区域协调发展具有重要意义。借助国土空间转移矩阵、标准差椭圆、核密度分析、空间计量模型等方法,揭示1990~2020年长江中游城市群不同经济发展阶段下国土空间格局演变特征及驱动机制。主要结论如下:(1)长江中游城市群国土空间类型主要占比从高到低依次为生态空间、农业空间、城镇空间;不同发展阶段下国土空间格局变化特征存在显著差异。(2)城镇-农业-生态空间互竞形成了“一增双减”的国土空间格局,且随着经济发展阶段的提升,不同国土空间类型间呈现出更加繁杂多样的转换模式,耕地、绿地也越容易流失。(3)城镇空间由主核数量较少且集聚特征不明显转变为多核扩散且高值区增加,重心变化较为剧烈;农业空间次核数量增加,高值区域明显减少,空间破碎化程度较高,重心变动较为稳定;生态空间的核密度由空间集中转变为空间破碎,西北地区变化较为明显。(4)国土空间格局形成受到自然、人口、经济等多重因素驱动,各因素对不同空间的影响程度及方向存在差异。应充分考虑长江中游城市群未来发展定位,加强国土空间分类管理,协调国土空间格局各驱动因素,以期为新时代长江中游城市群“三区”空间协调健康可持续发展提供理论依据和决策参考。

以青香蕉为原料提取多酚,利用超高效液相色谱-四极杆-静电场轨道阱质谱联用技术对多酚提取物进行成分鉴定,并通过体外实验评价香蕉果肉多酚对α-淀粉酶和α-葡萄糖苷酶活性的抑制作用,探究青香蕉降血糖的部分机制。结果表明:青香蕉果肉多酚提取物中共鉴定出28种化合物,包括21种多酚类化合物、2种有机酸、3种鞣花单宁代谢产物、以及香兰素和香豆素,检测到香蕉果肉中含有秦皮乙素、金丝桃苷、紫云英苷3种多酚类化合物,此外,二甲基鞣花酸和尿石素A为主要色谱峰;体外实验结果显示,香蕉果肉多酚对α-淀粉酶和α-葡萄糖苷酶均存在抑制作用,质量浓度为1.0 mg/mL时,对α-淀粉酶抑制率为(76.25±3.79)%,半抑制质量浓度(half maximal inhibitory concentration,IC50)为0.53 mg/mL;质量浓度为160μg/mL时,对α-葡萄糖苷酶抑制率为(92.54±0.69)%,IC50为35.76μg/mL。因此,多酚可能是青香蕉能够降血糖的活性成分之一。
