ABSTRACT
Objective:To study the current status of research in the field of iodine nutrition for pregnant women and to detect the hot spots and future trends in the field of iodine nutrition for pregnant women.Methods:Using "pregnant women" and "iodine" as search terms, we searched the literature related to iodine nutrition in pregnant women from January 2000 to December 2021 in China Knowledge Network (CNKI) database, Wanfang database and Chinese Medical Journal Full Text Database. CiteSpace 6.2.2.0 software was used to sort out the publication status, core authors and research hotspots of the papers.Results:A total of 879 valid papers were included, with an overall number of publications increasing trend from 2000 - 2021 and a decline after 2017. Among the 879 papers, 29 first authors were core authors (M≈3), and 109 papers were published, accounting for 12.40% of the total literature; several research groups with relatively stable collaborative relationships had been formed, with the larger collaborative team of Chen Zupei and Zhang Wanqi at Tianjin Medical University. Keyword co-occurrence analysis showed that pregnant women, urinary iodine, and iodine nutrition were high-frequency keywords; keywords with mediated centrality > 0.07 were pregnant women (0.48), pregnancy (0.40), urinary iodine (0.37), iodine deficiency disorders (0.25), iodine nutrition (0.20), thyroid (0.12), thyroxine (0.10), infants and children (0.09). The analysis of the emergent words showed that the evolution of iodine nutrition research themes in pregnant women was broadly based on studies of iodine nutrition monitoring results in key populations such as newborns and infants from 2000 - 2011, studies such as the range of thyroxine reference values during pregnancy from 2012 - 2016, and changes in iodine nutrition status of pregnant women and children after adjustment of iodized salt concentration from 2017 - 2021. The clustering results showed that a total of 355 keywords were aggregated to yield 10 clusters, and the average profile value of clusters (Silhouette) > 0.8, which was a reasonable clustering result; the study topics can be divided into three major categories, iodine nutrition and goiter monitoring results in key populations, thyroid hormones and pregnancy outcomes during pregnancy, and studies on thyroid-related diseases.Conclusions:Iodine plays an important role in the health of pregnant women and their offspring, and changes in the iodine nutrition status of pregnant women should be closely monitored. In response to the new trends of change that are currently present, multidisciplinary cooperation should be developed to respond to social concerns and jointly promote the maintenance of iodine nutrition in pregnant women at appropriate levels.
ABSTRACT
Introduction?Chronic obstructive pulmonary disease (COPD) and bronchial asthma are the most common chronic respiratory illnesses. COPD is one of the three most common causes of death worldwide. The main burden of mortality from COPD is seen in Latin America, sub-Saharan Africa, India, China, and South-East Asia. Absence of true prevalence values and mortality burden hinder planning and operationalization of public health interventions for prevention, control, and treatment of the disease. Further, the aggregated value of prevalence estimates calculated for a whole city or a larger geographical area does not provide the location of patients and presence of locally prevalent risk factors. The objective of this study was to understand the spatial distribution of COPD in a large, highly polluted city of a developing country. Materials and Methods?A cross-sectional community-based study was conducted in the National Capital Territory of Delhi (NCTD). All surveyed households were geocoded. GOLD screening criteria and pulmonary function tests using portable digital spirometer were used for diagnosis of COPD. Results?Results are presented as a series of maps depicting spatial epidemiology. Overall prevalence rate was 9.8/1,000 population. Highest prevalence was seen in industrial area. Most of the spatial hotspots were seen in industrial and slum areas. Similarly, Kernel density was also highest in industrial area. Conclusion?In the city of NCTD, we found the COPD being distributed in all types of habitations but spatial distribution helped us understand clustering of cases and compare prevalence rates in subunits of residential clusters within a metropolitan city.

ABSTRACT
The research on the processing mechanism of Chinese medicine is the key and core foundation to improve processing technologies of Chinese medicine, formulate the quality standards of Chinese medicinal pieces, enhance the clinical efficacy of Chinese medicine, enrich Chinese medicine processing theories, and promote the development of Chinese medicine processing. Many researc-hers have conducted in-depth exploration on the processing mechanism of Chinese medicine in the 20 years in the 21 st century. Significant progress has been made in the transformation of chemical components during the processing, the change of active components in the body, the law of toxicity attenuation in the processing of toxic Chinese medicine, the mechanism of efficacy enhancement and toxicity attenuation of processing with auxiliary materials, and the application of new biomedical technologies. At present, the processing mechanism of multiple Chinese medicines has been preliminarily clarified, which has greatly promoted the development of Chinese me-dicine processing. The development of the processing mechanism of Chinese medicine reveals that the in vitro transformation of chemical components is combined with the in vivo absorption, transport, and metabolism, and the macroscopic biological effects of the organism are combined with the cells, molecules, targets, and pathways in the study of the processing mechanism of Chinese medicine. More attention has been paid to exploring the processing mechanism from the overall level, and a modern systematic research system on the processing mechanism of Chinese medicine has been initially formed. To further promote the scientific development of Chinese me-dicine processing, the present study proposed that the research on the processing mechanism of Chinese medicine should take Chinese medicine properties into account, focus on the influence of disease condition on the mode of action and effect strength of the drugs, comply with the characteristics of clinical compound compatibility of Chinese medicine, use the holistic view research strategies of systems bio-logy, and deeply explore the processing mechanism of Chinese medicine from traditional Chinese medicine theories and the characteristics of clinical medication of Chinese medicine.

ABSTRACT
BACKGROUND: With the continuous development of three-dimensional (3D) printing technology and bone tissue engineering, more and more studies have applied 3D printing technology to bone tissue engineering, but the main research status, hot spots and development trend are not clear enough. OBJECTIVE: To explore the current research status, hotspots and development trends of this field through the literature metrology and visual analysis of research hotspots of 3D printing and bone tissue engineering. METHODS: The CNKI database was searched under the theme of “3D printing and bone tissue engineering research”. Based on the quantitative visual analysis method of CNKI literature, the author made a statistical analysis on the trend of the number of publications, publishing institutions and journals of the application of 3D printing technology in bone tissue engineering. VOSviewer software was used to analyze the author collaboration and keyword co-occurrence network of the literature, and the hot research topic was interpreted based on the literature. RESULTS AND CONCLUSION: (1) A total of 469 effective articles related to 3D printing and bone tissue engineering were retrieved. Since 2014, the research on 3D printing and bone tissue engineering has shown a steady growth trend. Chinese Journal of Tissue Engineering Research and Jilin University are the most published journal and institution in this field, respectively. The authors of the literature form five major groups, but there is very little cooperation between the groups. (2) Keywords co-occurrence network shows that the contents revealed by keywords commonly clustering into four research topics (bone tissue engineering scaffold material, 3D printing technology and its application in orthopedics, 3D printing and joint replacement, and others) and the top 10 keywords (3D printing technology, computer aided technology, bone tissue engineering, tissue engineering, fracture, bone defect, hydroxyapatite, three-dimensional, replacement, titanium alloy) really reflect the present situation and the hotspots of current 3D printing and the bone tissue engineering research, which can provide a reference for researchers in this field when choosing a research direction.
