Abstract
OBJECTIVE To reveal the current research status on stem cell transplantation in the treatment of neonates with hypoxic-ischemic encephalopathy (HIE), and to summarize the recent hotspots of the research in this field. METHODS Using the key words of "stem cells" and "HIE", a computerized search was performed for the articles in English published before June 1, 2018 in PubMed, EMBASE, and Web of Science. Microsoft Office Excel 2013 was used for the statistical analysis of key words. Bicomb 2.0 and VOSviewer 1.6.6 were used for the cluster analysis of hot words and plotting of knowledge maps, respectively. RESULTS A total of 106 articles were included and 43 high-frequency key words were extracted. The words of "cell transplantation" and "hypoxia-ischemia" were in the core position of the co-word map. The cluster analysis showed that the studies of stem cell transplantation in the treatment of neonatal HIE mainly focused on umbilical cord blood cell transplantation (32.6%), mesenchymal stem cells and neural stem cells (29.5%), perinatal brain injury (28.1%), and other topics (9.8%). CONCLUSIONS In the current studies of stem cell transplantation in the treatment of neonatal HIE, umbilical cord blood cell transplantation, mesenchymal stem cells, neural stem cells, and perinatal brain injury are popular research topics at different levels.

Abstract
OBJECTIVE To investigate the current status of the application of 1H-magnetic resonance spectroscopy (1H-MRS) in neonates with hypoxic-ischemic encephalopathy (HIE), and to describe the trend of research in the field. METHODS PubMed, EMBASE, and Web of Science were searched for English articles published up to January 10, 2018, with the combination of key words and MeSH terms. The articles were screened according to inclusion and exclusion criteria. Excel 2016, Bicomb 2.0, and VOSviewer1.6.6 were used to analyze the key words, to perform a cluster analysis of hot words, and to plot the knowledge map. RESULTS A total of 66 articles were included, and 27 high-frequency key words were extracted. The results showed that 1H-MRS was mainly used in four directions of the clinical practice and scientific research on HIE. In clinical practice, 1H-MRS attracted wide attention as a clinical examination for HIE and a tool for prognostic evaluation; in scientific research, 1H-MRS was used in animal experiments and studies associated with mild hypothermia therapy. CONCLUSIONS As an auxiliary means of magnetic resonance imaging, 1H-MRS plays an important role in investigating the pathogenesis of neonatal HIE, improving existing therapies, and evaluating the prognosis of neonates with HIE.

Abstract
OBJECTIVE To investigate the current status of research on infantile cholestatic liver disease in China and future research trends. METHODS A co-word analysis was performed in October 2016. Document retrieval and screening were performed in the Chinese databases CNKI and Wanfang Data using "cholestasis" and "infant" as key words. Excel 2010 was used to establish a co-occurrence matrix of high-frequency key words, and Ucinet 6.0 and Netdraw were used to develop a visualized network of these high-frequency key words. RESULTS A total of 383 articles were included. The co-occurrence analysis showed that "infant" and "cholestasis" were the core of research in this field, and "infantile hepatitis syndrome", "neonate", "intrahepatic", "biliary atresia", "heredity and metabolism", "hepatitis", "cytomegalovirus", "jaundice", and "conjugated bilirubin" were main research topics. Most of the other articles focused on "parenteral nutrition", "hepatobiliary imaging", "gene mutation", and "liver biopsy". There were relatively few articles on surgical diagnostic techniques and treatment for this disease. CONCLUSIONS The research on infantile cholestatic liver disease in China focuses on etiology and differential diagnosis, and genetic diagnosis has become a hot topic in recent years. The research on treatment should be enhanced, and new diagnostic techniques are the research interest in future.

Abstract
OBJECTIVE To investigate the current status of studies on drug therapy for apnea of prematurity (AOP) in the past decade in China and abroad, and to describe the research trends in the field. METHODS CNKI and MEDLINE were searched with the key words "apnea of prematurity" and "treatment" for articles published in the past decade (January 2006 to December 2015). The articles were screened and the key words were extracted to establish the co-occurrence matrix. Ucinet 6.2 was used to plot the knowledge map. RESULTS A total of 26 Chinese key words and 20 English key words were included. Those in the center of the co-existent knowledge map of Chinses keywords were "preterm infants", "apnea", "primary apnea", "naloxone" and "aminophylline"; while "apnea", "preterm infants" and "caffeine" located in the central place of the co-existent knowledge map of English keywords. CONCLUSIONS Methylxanthines are still the major drugs for AOP; however, aminophylline is mainly used in China, while caffeine is mainly used in foreign countries. Other drugs such as naltrexone are also used in the clinical treatment of AOP.

Abstract
OBJECTIVE To introduce co-word analysis into the analysis of the current research status of childhood tuberculous meningitis, to compare the similarities and differences in research topics of the field in China and abroad over the past decade, and to discover the advantages and weak links in the study field in China. METHODS PubMed, CNKI, VIP, and Wanfang Data were searched for the articles which met the inclusion criteria. Ucinet 6.0 and Netdraw were used for co-occurrence analysis, and the co-article relationship between high-frequency key words was visualized. RESULTS A total of 226 articles abroad and 186 Chinese articles on childhood tuberculous meningitis were obtained. The figures for co-occurrence analysis of high-frequency key words in research articles on childhood tuberculous meningitis in China and abroad were successfully plotted. Compared with the studies in China, the studies abroad were more sophisticated and well-developed, with more studies on drug-resistant tuberculosis, the relationship between tuberculosis and AIDS, and the epidemiology of tuberculosis. The key words listed in the studies abroad were more standard. The studies in China on childhood tuberculous meningitis concentrated on vaccination and nursing. CONCLUSIONS In general, the studies on childhood tuberculous meningitis in China and abroad have the same directions. The studies abroad have a complicated network and use more standard key words. The studies on childhood tuberculous meningitis are well conducted in China. However, more studies are needed for drug-resistant tuberculosis, the relationship between tuberculosis and AIDS, and the epidemiology of tuberculosis in future.
