ABSTRACT
Background Certain metabolites are closely related to the occurrence and development of pulmonary fibrosis, and the related mechanism has not been fully elucidated. It is necessary to explore the trends of various metabolites and causes of pulmonary fibrosis. Objective To discuss the trends of publication and research hotspots of pulmonary fibrosis-related metabolites by bibliometrics. Methods With "pulmonary fibrosis" and "metabolites" in both Chinese and English as primary keywords, literature search was conducted through public online databases: PubMed, Web of Science, SinoMed, and CNKI. NoteExpress 3.0 and Excel 2019 were used to store and organize the collected literature. Analyses included publication year, number of papers, institution, country/region, and journal title. VOSviewer 1.6.10 was used for visual analysis. Keyword co-occurrence was analyzed by setting the minimum threshold for the occurrence of keywords to 5 times. Results The research on pulmonary fibrosis and associated metabolites in foreign language was earlier than that in Chinese language. Since the 1990s, the number of literature showed an increasing trend in both foreign and Chinese language literature. A total of 1 062 articles were published in foreign languages, of which 864 articles contained the authors’ address information. The authors in the United States published 340 articles, followed by China with 196 articles, and then Japan, Germany, and Italy. There were 728 relevant pieces of literature published in Chinese, 709 of which included the authors’ institution information and 350 institutions were involved. North China University of Science and Technology, Shanxi Medical University, Peking University, Zhengzhou University, China Medical University，and Soochow University were the top 6 by number of publication. A total of 255 Chinese journals published 728 Chinese articles, and among them 242 articles (33.24%) were published by 12 journals having published more than ten articles per journal. A total of 1062 articles were published in 609 foreign language journals, and among them 179 articles (16.85%) were published by 8 journals with more than 15 articles published by each journal. The results of keywords co-occurrence analysis suggested that pulmonary fibrosis in association with glucose metabolism, lipid metabolism, amino acid metabolism, nucleotide metabolism, and biological oxidation were the common themes studied at home and abroad. Conclusion The number of publications on pulmonary fibrosis and metabolites has been on the rise in recent years, and the research hotspots include glucose metabolism, lipid metabolism, amino acid metabolism, nucleotide metabolism, and biological oxidation.
ABSTRACT
Objective To investigate the correlation between vital capacity, pulmonary ventilation and morphological parameters among children living in different altitude areas, so as to provide a reference basis for the development of prevention and control strategies for high altitude illness. Methods From January 2019 to June 2020, primary and secondary school students aged 7 to 15 years old were randomly selected from three different altitude areas, which were Xining (2 260m, low altitude group), Haixi (2 900m, medium altitude group), and Yushu (4 493m, high altitude group), respectively. The vital capacity, pulmonary ventilation and morphological parameters of the selected children were recorded. Results The vital capacity, pulmonary ventilation and morphological parameters showed statistically significant difference among three groups (P<0.05). The vital capacity and pulmonary ventilation were positively correlated with lung volume, but negatively correlated with lung density and lung artery diameter (P<0.05). Logistic regression analysis showed that there were three factors affecting children's vital capacity and lung ventilation: mean lung density, total lung transverse diameter, and total lung volume (P<0.05). Conclusion The monitoring of lung morphological indexes, mean lung density, total lung transverse diameter, and total lung volume can effectively judge children's lung function, and have certain value in the prevention and treatment of related high-altitude illness.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the clinical efficacy differences between acupuncture combined with 40-min penetration moxibustion and 60-min penetration moxibustion at back-points for insomnia of insufficiency of heart and spleen type.</p><p><b>METHODS</b>Sixty patients of insomnia with insufficiency of heart and spleen type were randomly assigned into a 40-min group and a 60-min group. The two groups were treated with acupuncture at Jueyinshu (BL 14), Xinshu (BL 15), Geshu (BL 17), Pishu (BL 20), Shendao (GV 11) and Zhiyang (GV 9). With moxibustion box, the penetration moxibustion was applied at the back until sweating and redness on the back. The moxibustion was given for 40 min in the 40-min group and 60 min in the 60-min group. The treatment was given once a day, five days per week. Each session was consisted of 5 treatments, with an interval of 2 days between session and totally 4 consecutive weeks were provided. The Pittsburgh sleep quality index (PSQI), TCM symptom scale were observed and recorded before and after treatment in the two groups. The even temperature at raising period, effective period, reducing period, as well as minimum high temperature, comfortable temperature, minimum cold temperature and medication status were compared; also the effect was compared between the two groups.</p><p><b>RESULTS</b>The total effective rate was 96.6% (28/29) in the 60-min group, which was higher than 89.3% (25/28) in the 40-min group (<0.05). Compared before treatment, the total score of PSQI and sleep quality, sleep time, sleep efficiency, sleep disorder, daytime dysfunction as well as the total TCM symptom score and its drowsiress in the morning, palpitation, amnesia, appetite were reduced after treatment in the 40-min group (all<0.05). After treatment, the total score and each score of PSQI as well as total score and each score of TCM symptom scale were reduced after treatment in the 60-min group (all<0.05). After treatment, the total score and each score of PSQI as well as total score and each score of TCM symptom scale were significantly different between the two groups (all<0.05).</p><p><b>CONCLUSIONS</b>Acupuncture combined with penetration moxibustion can improve the symptomsof insomnia with insufficiency of heart and spleen type, which is more significant in the 60-min group, indicating prolonged time of penetration moxibustion can improve sleep latency.</p>
ABSTRACT
Objective To study the morphological characteristics of eyes of female Uygur youth for providing the relevant data for eye aesthetic plastic surgery.Methods Compared with 150 cases of Han youth in the same school,the somatological survey was carried out in 150 female Uighur college students with the morphological characteristics of the eyes and good facial harmony.SPSS 17.0 was used for statistical analysis of the measured data in groups divided according to different race.Results 59.3％ (89/150) of the Uighur young women had prominent brow ridges tall nose and superior orbit cave,18.7％ (28/150) of them were similar to the Han type of eye,and 22.0％ (33/150) in between.The rate of epicanthus in Uighur women was 28.0％ (42/150),which was significantly lower than the Han nationality women 62.7％ (94/150).Double eyelid incidence was 96.7％ (145/150),which was significantly higher than that of Chinese Han women 67.3％ (101/150).There was a no statistically significant difference between them in palpebral fissure length inner canthic diameter and outer canthic diameter (P＞0.05),but a statistically significant difference was found in the height of palpebral fissure,the width of double eyelid and the distance between the eyebrow eyelid (P＜0.05).Conclusions The Uighur women's eye morphology has dual characteristics of Caucasoid and Mongoloid.The data have great significance and value in guiding the eye's cosmetic plastic surgery.
