ABSTRACT
AIM: To explore the current research progress, hot spots and future development trends of myopia in children and adolescents at home and abroad, thus providing references for the further research on the field.METHODS: Using China National Knowledge Infrastructure(CNKI)and Web of Science(WOS)as data sources, the literature on myopia in children and adolescents from January 1, 2003 to December 31, 2022 was collected. Visual analyses were conducted based on the quantity of the published articles, authors, publishing institutions, journals as well as keyword co-occurrence, clustering, timeline graph and emergence by using the VOSviewer and CiteSpace.RESULT: The number of publications on myopia research has increased steadily both articles in Chinese and English. Xian-Gui He and Saw, Seang-Mei have published the most papers, and the Chinese Journal of School Health and Investigative Ophthalmology & Visual Science published the most related articles. Shanghai Eye Disease Prevention and Treatment Center, and Sun Yat-sen University are the institutions with the most publications in the area. Clinical observation is the main focus of research both domestically and internationally, with orthokeratology, outdoor activities, axial length, prevalence, and influencing factors attracting much attention.CONCLUSION: Current research on myopia in children and adolescents focuses on the epidemiology, intervention measures, and biological parameters of the condition. Future research on myopia epidemiology is likely to become a major focus of research in this area.
ABSTRACT
OBJECTIVE@#To observe the clinical therapeutic effect of CO2 laser moxibustion on endometriosis related pelvic pain of cold coagulation and blood stasis.@*METHODS@#A total of 76 patients with endometriosis related pelvic pain of cold coagulation and blood stasis were randomized into a laser moxibustion group and a sham laser moxibustion group, 38 cases in each group. In the laser moxibustion group, moxibustion was applied at bilateral Zigong (EX-CA 1) using CO2 laser moxibustion instrument. In the sham laser moxibustion group, the manipulation of moxibustion was same as the laser moxibustion group, without laser output. The treatment was given once every other day, 30 min each time, 3 times a week for 4 weeks in both groups. Before and after treatment and follow-up of 3 months after treatment, the scores of Gracely box scale (GBS) and visual analogue scale (VAS) were observed, the usage of non-steroidal anti-inflammatory drug for the duration of the treatment and the average days of taking drugs were recorded in both groups.@*RESULTS@#Compared before treatment, the GBS and VAS scores were decreased after treatment and during follow-up in the laser moxibustion group (P<0.05), while those in the sham moxibustion group had no significant differences (P>0.05). Compared with the sham moxibustion group, the GBS and VAS scores were decreased after treatment and during follow-up (P<0.05), the cases and average days of taking drugs were less in the laser moxibustion group (P<0.05).@*CONCLUSION@#CO2 laser moxibustion can improve the pain symptom in patients with endometriosis related pelvic pain of cold coagulation and blood stasis, and reduce the use of analgesic drugs.

Objective: To study on the antitumor mechanism of artesunate in the treatment of liver cancer based on gas chromatography-mass spectrometry (GC-MS). Method: CellTiter-Glo® Luminescent Cell Viability Assay was used to detect activity of artesunate with different concentrations (0, 12.5, 25, 50, 100 μmol·L-1) on human liver cancer Huh7, SMMC-7721 cells for 24, 48, 72 h. GC-MS was employed to analyze the changes of metabolites of artesunate in two kinds of hepatoma cells (Huh7, SMMC-7721) for 24 h. The data was preprocessed by Postrun Analysis 4.41 workstation. Partial least squares-discriminant analysis (PLS-DA) was used to analyze two sets of differential metabolites and to analyze metabolic pathways of differential metabolites based on MetaboAnalyst 3.0 software. Result: Compared with the normal group, after two kinds of liver cancer cells was treated by artesunate, a total of 39 identical metabolites in the cells have undergone significant changes, which were mainly related to five metabolic pathways,including biosynthesis of aminoacyl-transfer RNA (tRNA), metabolism of alanine, aspartic acid and glutamic acid, metabolism of glycine, serine and threonine, metabolism of arginine and proline, metabolism of glutathione. Conclusion: Artesunate (12.5-100 μmol·L-1) can inhibit the growth of liver cancer cells (Huh7, SMMC-7721), it mainly involves five metabolic pathways, which may be the pathway of artesunate against liver cancer.
