Background: Delayed gastric emptying(DGE) is one of the most common complications after pancreaticoduodenectomy(PD). DGE represents impaired gastric motility without significant mechanical obstruction and is associated with an increased length of hospital stay, increased healthcare costs, and a high readmission rate. We reviewed published studies on various technical modifications to reduce the incidence of DGE. Data sources: Studies were identified by searching Pub Med for relevant articles published up to December 2022. The following search terms were used: “pancreaticoduodenectomy”, “pancreaticojejunostomy”, “pancreaticogastrostomy”, “gastric emptying”, “gastroparesis” and “postoperative complications”. The search was limited to English publications. Additional articles were identified by a manual search of references from key articles. Results: In recent years, various surgical procedures and techniques have been explored to reduce the incidence of DGE. Pyloric resection, Billroth II reconstruction, Braun's enteroenterostomy, and antecolic reconstruction may be associated with a decreased incidence of DGE, but more high-powered studies are needed in the future. Neither laparoscopic nor robotic surgery has demonstrated superiority in preventing DGE, and the use of staplers is controversial regarding whether they can reduce the incidence of DGE. Conclusions: Despite many innovations in surgical techniques, there is no surgical procedure that is superior to others to reduce DGE. Further larger prospective randomized studies are needed.

随着全球化进程的不断推进,各国之间的文化交流也越来越频繁,加强全球文明交流互鉴,推动我国国际传播能力的全面提升业已箭在弦上。宣传思想文化工作要在国际传播的视域下开展,围绕“一带一路”倡议和人类命运共同体进行的国际传播实践也要遵循文明交流互鉴的原则。要着重讲好中国传统文化故事和中国社会治理故事,为国际传播实践扫清外部障碍,营造良好的外部舆论环境,从构建“以我为主”的对外话语体系、推进兼具国际视野的媒体深度融合、创造国际传播效果的整合评估机制三个层面综合发展我国国际传播能力。

聚焦俄乌冲突期间的国际媒体舆论场,从舒德森“故事模式”新闻理论出发,对具有“故事模式”特征的媒介内容加以分析。研究认为,当下的国际新闻舆论场仍具有舒德森理论中的“故事模式”特征,且主要分为故事的预热、导向、渠道、议程、力度、功能六个维度。因此,国际舆论场中的新闻不仅是载于媒介之上的信息流,更在一定程度上成为历史的书写范畴和不同主体间的情绪对抗缘由。据此,中国未来国际传播事业发展亟须争取国外知名媒体人、政客的言论支持,利用外交官、机构媒体、自媒体、海外华侨华人的影响力,加强外宣合力,主动参与国际舆论的议题设置,呈现多元和真实的中国声音。

有明一代,云南社会发生了极大的变革。作为“神权与世俗皇权融合产物”和“封建皇权象征”的道教至尊神玉皇,在王朝实施边疆治理过程中发挥过重要的社会教化作用。在明代地方官倡导兴建玉皇阁的碑文叙事中折射出王朝治理边疆的隐喻,遍布地方社会的玉皇阁、流行于民间的玉皇会、斋醮中的玉皇朝科是云南盛行玉皇信仰的主要表现。在中原王朝边疆治理政策、地方官吏、土司、移民、僧道、士绅的共同推动下,玉皇信仰逐渐深入云南地方社会,在这一过程中玉皇信仰成为云南多民族交流、融合、认同的文化象征符号。

Reducing the control error is vital for high-fidelity digital and analog quantum operations. In superconducting circuits, one disagreeable error arises from the reflection of microwave signals due to impedance mismatch in the control chain. Here, we demonstrate a reflection cancelation method when considering that there are two reflection nodes on the control line. We propose to generate the pre-distortion pulse by passing the envelopes of the microwave signal through digital filters, which enables real-time reflection correction when integrated into the field-programmable gate array (FPGA). We achieve a reduction of single-qubit gate infidelity from 0.67% to 0.11% after eliminating microwave reflection. Real-time correction of microwave reflection paves the way for precise control and manipulation of the qubit state and would ultimately enhance the performance of algorithms and simulations executed on quantum processors.
