Background:Studies on myocardial infarction(MI)based on large medical databases have become popular in recent years.The influence of the National Inpatient Sample(NIS),the largest collection of administrative healthcare data across the United States,on the field of MI has not been well investigated.This study aimed to quantify the contribution of NIS to MI research using bibliometric methods.Methods:We searched the Web of Science Core Collection database to identify publications on MI using NIS from 2000 to 2022.Bibliometric indicators,such as the number of publications,citations,and Hirsch index(H-index),were summarized by years,authors,organizations,and journals.VOSviewer and CiteSpace software were used to analyze the keywords and trends of the hot spots.Results:A total of 342 articles on MI based on NIS were included.A significant growth in outputs related to MI using the NIS from 2000 to 2020 was observed.The publications were mainly from the United States.The Mayo Clinic was the most prolific institution and had the most citations and the highest H-index.The American Journal of Cardiology ranked first among journals with the highest number of publications,citations,and H-index.Mortality and healthcare management are the main focuses of this field.Personalized risks and care are receiving increased attention.Conclusion:This study suggests that NIS significantly contributes to high-quality output in MI research.More efforts are needed to improve the impact of knowledge gained from the NIS on MI.

当前,百年变局加速演进,国际形势变乱交织,各国安全焦虑上升。在此背景下,共话全球安全,共商应对之道,具有十分重要的现实意义。国际安全形势令人担忧,既来自传统与非传统安全威胁的叠加影响,也源于人工智能、气候变化、太空极地等带来的潜在挑战。特别是一些国家以应对安全风险和挑战为由,泛化安全概念、模糊安全边界、渲染安全威胁,打地缘博弈的“小算盘”,搞封闭排他的“小圈子”,进一步激化了全球安全复杂紧张态势。

We have numerically presented an actively mode-locked fiber laser with tunable repetition rate based on phase modulator.By finely optimizing intra-cavity parameters,the ultrashort pulses with tunable repetitive frequency at giga hertz level can be easily generated due to the balance between dispersion and nonlinearity in the fiber laser cavity.When the pulse frequency is changed from 1.0 GHz to 4.2 GHz,the spectral width increases from~15.65 nm to~27.25 nm.In addition,the corresponding pulse duration decreases from~81.59 ps to~31.57 ps.Moreover,these output pulses with giga hertz repetitive rates and the picosecond widths can be further compressed by using the reasonable dispersion medium.For the pulse regime with repetition frequency at giga hertz level,the obtained smallest pulse duration is about~62 fs based on chirp pulse compression.We hope that these simulation results can promote further research and application in the ultrashort pulse lasers with high repetition rate.

In the surgery of lumbar disc herniation(LDH),the nerve root retractor is used to pull the nerve root to prevent damage.The traditional medical nerve root retractor cannot quantify the force on the nerve root.In order to improve the nerve root retractor,this paper proposes an intraoperative lumbar neurological force monitoring system.The core module of this system is the improved nerve root retractor equipped with the high density flexible pressure sensor array.The high density microneedle array and multiple pressure detection units are used in the pressure sensor to realise sensitive pressure monitoring in a narrow surgical operation area.The sensing area is 4 mm×17 mm,including 6 detection units.The sensitivity of sensor is 67.30%/N in the range of 0-5 N.This system is used for in vitro animal experiments,which can continuously detect pressure.

产业学院是职业院校主动对接国家战略性新兴产业和区域主导产业发展需求,多主体联合共建、产教融合与科教融汇特征明显的实体学院。由于缺乏具体的政策引导、清晰的功能界定和成熟的范式借鉴,职业院校在产业学院治理实践中,在概念、主体、运行、发展等方面存在诸多困境,这限制了产业学院应有价值的发挥,职业院校需要在明晰建设逻辑的基础上,以人才发展和技术创新织牢主体间的利益链,以利益机制保障长期运行,以契约治理构建明晰的权责体系,以多元协同形成高效的治理体系,进一步优化产业学院的建设策略。
