Objective: To analyze the characteristics of scientific papers in the field of global liver diseases published by Chinese scholars that were retracted for diverse reasons from the Retraction Watch database, so as to provide a reference to publishing-related papers. Methods: The Retraction Watch database was retrieved for retracted papers in the field of global liver disease published by Chinese scholars from March 1, 2008 to January 28, 2021. The regional distribution, source journals, reasons for retraction, publication and retraction times, and others were analyzed. Results: A total of 101 retracted papers that were distributed across 21 provinces/cities were retrieved. Zhejiang area ( n = 17) had the most retracted papers, followed by Shanghai ( n = 14), and Beijing ( n = 11). The vast majority were research papers ( n = 95). The journal PLoS One had the highest number of retracted papers. In terms of time distribution, 2019 ( n = 36) had the most retracted papers. 23 papers, accounting for 8.3% of all retractions, were retracted owing to journal or publisher concerns. Liver cancer (34%), liver transplantation (16%), hepatitis (14%), and others were the main areas of retracted papers. Conclusion: Chinese scholars have a large number of retracted articles in the field of global liver diseases. A journal or publisher chooses to retract a manuscript after investigating and discovering more flawed problems, which, however, require further support, revision, and supervision from the editorial and academic circles.

Rhodium as a national strategic reserve metal, has the irreplaceable role of other metals, but its resources are mainly concentrated in some countries in South Africa, and rhodium resources are very scarce in our country. In the process of industrialization in China, a large number of rhodium-containing homogeneous spent rhodium catalysts are produced, of which rhodium content is much higher than that of ores, so it is particularly important to recover rhodium from rhodium-containing homogeneous spent catalysts. By referring to the relevant literature, this paper summarized the recycling methods and prospected its prospects. [ABSTRACT FROM AUTHOR]

Paper has always been a cheap and convenient substitute for more expensive materials or clumsy objects which are useful for other purposes and it is sometimes suitable for uses in which no better materials will serve. Today, paper and paper products have hundreds of uses in communication, business, industry, and household operations, as they are found everywhere in daffy life. Many of these uses can be traced back to centuries ago when paper was used as extensively and variously in China as it is elsewhere in the world during the modern times. Generally speaking, paper was used for wrapping and padding not long after its invention in the Western Han; for writing from the Later Hart; for cutting into designs, making stationery, fans, and umbrellas from the third or fourth century; for clothing, furnishing, visiting cards, kites, lanterns, napkins, and toilet purposes no later than the fifth or sixth century; for family ceremonies in the seventh; for state sacrifices and making replicas of real objects from the eighth; and for playing cards, for wearing as protective arms, and in lieu of cash as a medium of exchange from the ninth century. In other words, all these uses for graphic and decorative arts, for commercial and ceremonial occasions, and for household and recreational purposes existed in China before paper was introduced to the West in the ninth century. While the use of paper in writing, printing, stationery and decoration is discussed in a separate article, this study traces the origin and development of the popular and household use of paper and paper products as recorded in literature or found in recent discoveries of early specimens and artifacts.

The pulp and paper industry is an important industry that is closely related to national socioeconomic development. To understand the historical trends of resource consumption and environmental pollution, we conducted an economy-wide material flow analysis and quantitatively evaluated the dynamic characteristics of input-output balances, material metabolism intensity, and resource recycling rate of China's pulp and paper industry, from 2005 to 2017. The results indicate downward trends in the material inputs and outputs of China's pulp and paper industry from 2005 to 2017, with water contributing over 90% of the totals. In recent years, with the continuous optimization of the raw material structure of the paper industry, the proportion of non-wood pulping has dropped from 42% to 13% and has been replaced by mainly waste paper pulping and wood pulping. Resource consumption can still be greatly reduced. In 2017, the amount of direct material input per ton of paper and paperboard had decreased by 67% from 2005 to 26 t. The consumption of fresh water per ton of paper and paperboard dropped by approximately 69% over the study period, whereas the water recycling rate increased significantly, reaching 77% in 2017. At present, the production of paper and paperboard is increasingly dependent on the input of domestic waste paper and imported wood, the proportions of which have increased from 21% and 9% in 2005 to 60% and 31% in 2017, respectively. However, the rate of domestic waste paper recycling is relatively low, and measures such as strengthening the construction of the recycling system and educating the residents about recycling are needed to alleviate the shortage of raw materials caused by restrictions on waste paper imports.

Short-chain chlorinated paraffins are persistent organic pollutants, and chlorinated paraffins were widely used as sizing agent in the paper industry. In order to investigate the levels and risk assessment of short-chain and medium-chain chlorinated paraffins in the paper mill plant, the surface soil and soil of different depths were collected.The concentrations, congener group profiles of short-chain chlorinated paraffins (SCCPs) and medium-chain chlorinated paraffins (MCCPs) in soil were determined by two-dimensional gas chromatography coupled with electron capture-negative ion mass spectrometry. The SCCPs and MCCPs concentrations were 42-3853 ng·g -1 and 34-2091 ng·g -1 . The chlorine contents were 59.9%-61.9% and 48.7%-52.8%. The concentrations of SCCPs and MCCPs were different in the soil collected in different sampling site. The concentration of SCCPs and MCCPs were relatively higher in soil of sewage treatment area and coating area. The CP levels in soil from the paper mill plant were at a high level compared with those in other regions. C 10 Cl 6-7 and C 14-15 Cl 5 were the main congener groups in most soil samples. The results of principal component analysis showed that the CP52 commercial products may be sources of SCCPs and MCCPs in the soil. The risk quotient (RQ) for SCCPs and MCCPs were assessed in soil of paper mill plant. The results showed that the RQ values for SCCPs in soil ranged from 0.01 to 0.73 which are the medium risk, and the RQ values for MCCPs in soil ranged from 0 to 0.07, which are the low risk. The human exposure values of children and adults are lower than TDI[10 μg·(kg·d) -1 ] in both cases. The health risks caused by non-dietary exposure under paper mill area are low.

There are two extreme ways in the use of philosophical concepts in China's academic research activities: First one is to completely remove the relationship between philosophical concepts and phenomena; Second, a large number of philosophical concepts are used. At present, there is a problem of piling up a large number of philosophical concepts in some humanities academic papers, that is, there is an excessive use of philosophical academic concepts. The reason is that the authors of these humanities academic papers try to use a lot of philosophical concepts to increase the amount of information and highlight the novelty of the papers. But when they do that, they do not carefully consider the rationality of the relationship between these philosophical concepts and the concepts connected with them, which results in arbitrariness in use and affects the seriousness of their judgments and the scientificity of their arguments. For this reason, in the humanities academic papers, we need to understand and grasp the rationality and appropriateness of the use of philosophical concepts, so as to enhance the preciseness of reasoning and the correctness of conclusions in this kind of academic papers, and thus enable China's philosophy and social science research to produce more high-quality academic works.

Papermaking is one of the four great inventions in ancient China; the most influential genre of Chinese literature is poetry; and paper and poetry are therefore both our "national quintessence" of which the Chinese people are proud. The period people use the tablets of bamboo or pieces of silk had lasted several thousand years before paper was created, when the instantaneous exchange of emotion had to be oral, and that is why the way of verbal expression used to be oral songs, but not textual poetry; meanwhile, owing to the heaviness and inconvenience of the media, the written texts were only used for conveying the diachronic tradition, not suitable for special circulation. The invention of paper and its wide usage made the Chinese culture step into the Middle Ancient Time and hence led to the boom of textual literature in the Wei and Jin Dynasties. Thereafter, poetry changed its form from oral to written texts, which in turn led to the changes in the importance of the literary nature and the poetic ambience of poetry. The revolution of poetry relevant to the aesthetic nature and the formal rhyme was hence the result by using the material media of paper, demonstrating the influence of the material upon the spirit.
