Objective:To evaluate the efficacy of exercise on preventing falls in the elderly. Methods:Literatures of randomized controlled trials about exercises for prevention of falls in the elderly were retrieved from Web of Science, PubMed, Cochrane Library and CNKI from 1980 to July, 2020. The qualities were evaluated with Review Manager 5.3, and the data were analyzed with R-Studio and Addis 1.16.6. Results:A total of 172 randomized controlled trials were finally included, with nine kinds of exercise intervention. The cognition and movement multitask training was the most effective to decrease fall rate (OR = 0.26, 95%CI 0.14 to 0.49, P < 0.05). The combined physical and whole body vibration training was the most effective to improve the score of Berg Balance Scale (d = 6.3, 95%CI 3.5 to 9.2, P < 0.05) and the time of Timed 'Up & Go' Test (d = -4.5, 95%CI -6.8 to -2.1, P < 0.05). The blood flow restriction training was the most effective to increase the lower limb muscle strength (d = 12, 95%CI 7.4 to 16, P < 0.05). Conclusion:The cognition and movement multitask training is the first recommended exercise to prevent falls in the elderly, followed by Taiji Quan and multimodal training. Gait practice or resistance training are the least effective. A variety of new intervention methods (blood flow restriction training, combined physical and whole body vibration training, Wit Fit training, etc.) may improve the physical function of the elderly, and need further researches.
摘要
The sustainable use of medicinal plants is the foundation of the inheritance of traditional Chinese medicine(TCM) and the acquisition of information on medicinal plants is the basis for the development of TCM. The traditional methods of investigating medicinal plant resources are disadvantageous in strong subjectivity and poor timeliness, making it difficult to real-time monitor medicinal plant resources. In recent years, remote sensing technology has become an important means of obtaining information on medicinal plants. The application of this technology has made up for the shortcomings of traditional methods. The open-access remote sensing data with medium spatial resolution satellites provide an opportunity for extracting information on medicinal plant resources. This study firstly introduced the principles of remote sensing technology, summarized the satellites and the parameters commonly used in the field of medicinal plant resources, and compared the survey methods of remote sensing technology with traditional methods. Secondly, it reviewed the applications of remote sensing technology in the extraction of information on the cultivation of medicinal plants and the common methods for extracting the planting structure information of medicinal plants based on remote sensing technology. Thirdly, the applications of remote sensing technology in the investigation and monitoring of medicinal plants were further analyzed with the research objects divided into wild and cultivated medicinal plants according to the characteristics of the habitats. Finally, it pointed out the key unsolved technical problems in the remote sensing monitoring of medicinal plant resources, and proposed solutions for the intelligent information processing of medicinal plants based on remote sensing big data, which is expected to provide references for the development of remote sensing technology in derivative application in medicinal plant resources.

<p><b>OBJECTIVE</b>To explore the significance of Lens culinaris-reactive alpha-Fetoprotein (AFP-L3) detection in primary hepatocellular carcinoma.</p><p><b>METHODS</b>AFP-L3 was isolated by using microspin column coupled with lens culinaris agglutinin (LCA), AFP and AFP-L3 were detected with chemiluminescent immunoassay, the proportion of AFP L3 levels were calculated, and the relationship between the elevated AFP-L3 (%) levels and benign and malignant liver disease was analyzed.</p><p><b>RESULTS</b>There were significant differences in positive rate between the patients of HCC, suspected HCC and other liver disease (81.80%, 73.68%, 11.80%, respectively, P < 0.05). Among the undetermined HCC (suspected HCC, liver disease) patients, 12 out of 21 cases of AFP-13 positive were diagnosed to be HCC within 6 months, and 6 of them were diagnosed to be the single small HCC at the early stage through B-Ultrasonic Diagnosis or CT. Among 62 cases of AFP-L3 negative, 3 cases were diagnosed to be HCC within 6 months and the risk of occurrence of HCC for AFP-L3 positive increased 11.9 times.</p><p><b>CONCLUSION</b>AFP-L3 has no correlation with AFP value, and it can be used as an independent HCC diagnosis factor. The detection of AFP-L3 has a significant implication for the identification of benign or malignant liver disease and the early stage predictive diagnosis of HCC while AFP increases.</p>
