BACKGROUND This is a secondary database study using the Brazilian public healthcare system database.AIM To describe intestinal complications(ICs)of patients in the Brazilian public healthcare system with Crohn’s disease(CD)who initiated and either only received conventional therapy(CVT)or also initiated anti-tumor necrosis factor(anti-TNF)therapy between 2011 and 2020.METHODS This study included patients with CD[international classification of diseases–10th revision(ICD-10):K50.0,K50.1,or K50.8](age:≥18 years)with at least one claim of CVT(sulfasalazine,azathioprine,mesalazine,or methotrexate).IC was defined as a CD-related hospitalization,pre-defined procedure codes(from rectum or intestinal surgery groups),and/or associated disease(pre-defined ICD-10 codes),and overall(one or more type of ICs).RESULTS In the 16809 patients with CD that met the inclusion criteria,the mean follow-up duration was 4.44(2.37)years.In total,14697 claims of ICs were found from 4633 patients.Over the 1-and 5-year of follow-up,8.3%and 8.2%of the patients with CD,respectively,presented at least one IC,of which fistula(31%)and fistulotomy(48%)were the most commonly reported.The overall incidence rate(95%CI)of ICs was 6.8(6.5–7.04)per 100 patient years for patients using only-CVT,and 9.2(8.8–9.6)for patients with evidence of anti-TNF therapy.CONCLUSION The outcomes highlighted an important and constant rate of ICs over time in all the CD populations assessed,especially in patients exposed to anti-TNF therapy.This outcome revealed insights into the real-world treatment and complications relevant to patients with CD and highlights that this disease remains a concern that may require additional treatment strategies in the Brazilian public healthcare system. 展开更多

Song China was a period in which China experienced a great increase in its population.Concurrently,the Song dynasty also experienced a rise in the frequency of epidemics and two major wars with the Western Xia and Liao dynasties during the 1000s and 1040s.The consequences of these changes were exacerbated by the increased geographical mobility of certain social groups such as traders and examinees attending civil service examinations.Thus,casualties of wars,epidemics,or disease,especially of people whose families were far away and could not care for them were left without care and“their corpses often lay bare along the roads.”This new social environment created a need for general relief.The Northern Song government(960-1127 CE),especially during the reign of Emperor Huizong,established an innovative public health system to address this issue.The public health system included poorhouses,public hospitals,and pauper’s cemeteries.The first were more of charity organizations,whereas the latter two promoted public health by providing medical services for the poor and burial for those that nobody cared for.In terms of rationale behind these institutions,on the one hand,they constituted an attempt to get the poor and homeless off the streets while providing them relief or burial.On the other hand,it seems that Huizong’s deep concern with medicine propelled him to design and implement a comprehensive public health system oriented to prevent contagion and outbreak of epidemics.This article depicts the background,the organization,and the functions of the system.The article also discusses the conditions and reasons that gave rise to such a unique undertaking by the Northern Song government. 展开更多

With the popularity of mobile intelligent terminal, user comments of App software is viewed as one of the research interests of social computing. Faced with the massive App software, most users usually view the other users’ comments and marks to selecting the desired App software. Due to the freedom and randomness of the network comments, the inconsistence between the user’s comment and mark makes it difficult to choose App software. This paper presents a method by analyzing the relationships among user’s comment information, the user’s mark and App software information. Firstly, the consistency between user’s comment information and App software information is judged. Then, through analyzing the grammar relationships among the feature-words, adverbs and the feature-sentiment-words in App software’s feature-sentimentword- pairs, the user’s emotional tendency about App software is quantified quantified combining with the dictionary and the network sentiment words. After calculating the user’s comprehensive score of App software, the consistency of App software’s user comment is judged by comparing this score and the user’s mark. Finally, the experimental results show that the method is effective. 展开更多

The purpose of this paper is to assess the operational efficiency of a public bus transportation via a case study from a company in a large city of China by using data envelopment analysis(DEA)model and Shannon’s entropy.This company operates 37 main routes on the backbone roads.Thus,it plays a significant role in public transportation in the city.According to bus industry norms,an efficiency evaluation index system is constructed from the perspective of both company operations and passenger demands.For passenger satisfaction,passenger waiting time and passenger-crowding degree are considered,and they are undesirable indicators.To describe such indicators,a superefficient DEA model is constructed.With this model,by using actual data,efficiency is evaluated for each bus route.Results show that the DEA model with Shannon’s entropy being combined achieves more reasonable results.Also,sensitivity analysis is presented.Therefore,the results are meaningful for the company to improve its operations and management. 展开更多

Although it is not the main duty for the People's Procuratorate to institute environmental public interest litigation proceedings, the existence of "reserve" prosecution right of plaintiff not only is beneficial to timely prevention and cure of environmental damage, but also contributes indispensable judicial supervision force to the environmental legality construction. In order to safeguard environmental public interests, many local prosecutorial organizations have practiced environmental public interests litigation. Since Chinese law has not made explicit stipulation on the function of the People's Procuratorate instituting environmental public interest litigation, the plaintiff's subject qualification for environmental public interest litigation instituted by the People's Procuratorate is still in question. In order to propel the People's Procuratorate to completely and fully exercise their power of supervision and prosecution, there shall be corresponding legislation that provides powerful guarantee for the People's Procuratorate instituting environmental public interest litigation. 展开更多

As a vital part of China's foreign relations,China's aid to Africa has scored great achievements.Based on data from the Afrobarometer Survey in 2010 and data from the database of China's aid to Africa in 2000-2010 co-created by the US Center for Global Development and AidData,this paper dissects the macro-and micro-level determinants of the African public's perception of the effectiveness of aid from China through an empirical analysis.As descriptive statistics reveal,the African public has a highly positive view of aid from China despite country differences.According to our further analysis of a multilevel model,aid recipients with higher levels of democracy and economic development have a more favorable view of aid from China,while the size and sector of aid from China are not correlated with public favorability.At the micro-level,age,gender,education,race and media consumption are positively correlated with the public perception of aid.In conclusion,China must refocus its future aid programs on livelihood and welfare that directly benefit local people,rather than simply increasing the amount of aid.In delivering its commitments to Africa,China must also attach importance to public communication and "telling the China story " in its international affairs to improve its national image and gain more recognition by the African people. 展开更多

With the advent of quantum computing,numerous efforts have been made to standardize post-quantum cryptosystems with the intention of(eventually)replacing Elliptic Curve Cryptography(ECC)and Rivets-Shamir-Adelman(RSA).A modified version of the traditional N-Th Degree Truncated Polynomial Ring(NTRU)cryptosystem called NTRU Prime has been developed to reduce the attack surface.In this paper,the Signcryption scheme was proposed,and it is most efficient than others since it reduces the complexity and runs the time of the code execution,and at the same time,provides a better security degree since it ensures the integrity of the sent message,confidentiality of the data,forward secrecy when using refreshed parameters for each session.Unforgeability to prevent the man-in-the-middle attack from being active or passive,and non-repudiation when the sender can’t deny the recently sent message.This study aims to create a novel NTRU cryptography algorithm system that takes advantage of the security features of curve fitting operations and the valuable characteristics of chaotic systems.The proposed algorithm combines the(NTRU Prime)and Shamir’s Secret Sharing(SSS)features to improve the security of the NTRU encryption and key generation stages that rely on robust polynomial generation.Based on experimental results and a comparison of the time required for crucial exchange between NTRU-SSS and the original NTRU,this study shows a rise in complexity with a decrease in execution time in the case when compared to the original NTRU.It’s encouraging to see signs that the suggested changes to the NTRU work to increase accuracy and efficiency. 展开更多

China's cormaaunications industry is an important part of the electronic information industry, and plays a significant role in the national informatization process. In 2006, China issued its National Plans for Medium and Long-term Development of Science and Technology (2006-2020) (NPMLDST). Since 2006, there has been a rapid increase in the number of citations of China's interna- tional papers in the field of communications. In accordance with the goals listed in the NPMLDST, China needs to over- take several competitors by 2020 to be among the top five countries in the field of natural science field. By comparing two Essential Science Indicators (ESI) (i.e., the total number of citations and the number of citations per paper) for China and other countries, China's annual growth rate is found to exceed that of other influential countries in the field of sci- ence and technology, and exhibits evident growth-type characteristics. Besides, our study also shows that the short- age of high-quality academic papers in China is the main obstacle to improving the impact of China's academic publications. 展开更多
