RESUMEN
Objective: To perform a bibliometric analysis of published research related to the use of traditional Chinese medicine (TCM) for the treatment of Coronavirus Disease 2019 (COVID-19). Methods: Research documents related to the use of TCM for prevention and treatment of COVID-19 published up to September 19, 2021, were retrieved from the Web of Science database. Bibliometrix R 4.0 software package was used to analyze data, including countries of publication, research institutions, journals, citations, and keywords. Further analysis was conducted to identify co-occurrence of keywords in the documents, including their titles and abstracts. Cooperative network analyses of authors, institutions, and countries of publication were also conducted. The classification types were statistically analyzed and the research progress of key TCMs was reviewed. Results: A total of 417 documents were included in our analysis. Of these, 85.13% originated in China. Of the 417 documents, 148 (35.5%) were published in journals with impact factors in quartile 1 and 164 (39.3%) in journals in quartile 2. The documents were mainly published in journals categorized as Medicine. The results of network analysis showed close cooperation between institutions and countries. Excluding disease- and drug-related keywords, the top four keywords were 'Systematic review', 'Network pharmacology', 'Medicine' and 'Molecular docking'. Keyword co-occurrence analysis showed 4 main keywords association groups. Statistical analysis of the TCM studies showed that Lianhua Qingwen capsule, Qingfei Paidu decoction, Shufeng Jiedu capsules and ReDuNing injection were the most studied Chinese medicines. Lianhua Qingwen capsules, Qingfei Paidu decoction, ReDuNing injection, and Shufeng Jiedu capsules were used in clinical, bioinformatics, and basic research. Toujie Quwen granule, Jinhua Qinggan granule, Shuanghuanglian oral liquid, Tanreqing injection, and Xuanfei Baidu decoction were used in clinical and bioinformatics research, although basic research on their mechanisms of action is lacking. Conclusion: Research intensity and recognition, as well as cooperation, in the field of Chinese medicine for the prevention and treatment of COVID-19 has increased. Research types are generally comprehensive, and investigated several TCM formulations that are specifically recommended by Chinese COVID-19 guidelines. However, comprehensive, in-depth research on their molecular mechanisms of action is still lacking. More basic research is thus needed to identify therapeutic mechanisms to standardize and validate the use of TCM in the prevention and treatment of COVID-19.
RESUMEN
Objective:To investigate the effect of upper limb pillow position on hemodynamic and safety of patients undergoing cerebellopontine angle tumor resection.Methods:Eighty-four patients receiving cerebellopontine angle tumor resection in our hospital from January 2016 to December 2019 were randomly divided into the experimental group (42 cases) and the control group (42 cases). Patients in the control group were placed in routine upper limb position, while patients in the experimental group were placed in upper limb pillow position. The data including systolic pressure, diastolic pressure, heart rate, saturation of blood oxygen were recorded on admission of operation room, completing placing body position, 30 minutes and 60 minutes after operation and after finishing the operation. The numbness/soreness of upper limbs and pressure injury rate was compared between the experimental group and the control group.Results:The rate of numbness/soreness of upper limbs were 2.4% (1/42) in the experimental group, 19.1%(8/42) in the control group, the differences were statistically significant ( χ2 value was 6.098, P<0.05). The stage 1 pressure injury were 2 cases in the experimental group, stage 1 and 2 pressure injury were 6 cases and 2 cases, respectively in the control group, the differences were statically significant ( Z value was 2.039, P<0.05). Conclusion:Upper limb pillow position of the operation side can reduce postoperative complication of patients undergoing cerebellopontine angle tumor resection, but will not increase the risk of abnormal hemodynamic fluctuation.
