RESUMEN
AIM: To explore the protective effect of astragalus glycyrrhiza decoction (AGD) on arsenic trioxide (ATO)-induced QT interval prolongation and its mechanism based on metabonomics. METHODS: The model of ATO-induced QT interval prolongation in rats was established, and ECG, blood routine, and metabonomics were detected, and the key targets were collected combined with network pharmacology. The possible candidate genes and pathways for the protective effect of AGD were screened by GO and KEGG enrichment analysis and then verified by experiments in vitro. RESULTS: AGD could significantly alleviate the ATO-induced QT interval of SD rats. GO enrichment analysis was mainly related to inflammatory response, reactive oxygen species, oxidative stress, inner cell vesicles, folds, inner cell vesicles, SMAD binding, R-SMAD binding, and signal receptor activator activity. KEGG analysis showed that it was mainly concentrated in the PI3K-Akt signal pathway, lipid and arteriosclerosis, FOXO signal pathway, TNF signal pathway, HIF-1, and other signal pathways. Through the H9c2 cell model in vitro, it was verified that AGD could reverse the expression of SIRT1 and FOXO1 proteins. CONCLUSION: AGD may improve the ATO-induced QT interval prolongation and reduce the cardiotoxicity of ATO by regulating the SIRT1 / FOXO1 signal pathway.

Objective:To construct training indexes of post competency of dental hygienist, and to provide objective basis for the establishment of the index system of the transition from dental nurse to dental hygienist in the future.Methods:The relevant literature of post competency of dental hygienist was searched from the databases such as PubMed, Medline, Web of Science, China National Knowledge Internet, Wanfang database. The search time was from the establishment of the database to March 2021. The expert letter inquiry questionnaire was designed through preliminary consultation.Delphi expert consultation was conducted for 20 dental experts from Beijing city, Chongqing city, Jiangsu province, Sichuan province, Jilin province from May to November 2021, and model indexes and weight assignment of post competency of dental hygienist were determined.Results:Three rounds of Delphi expert consultation were conducted, the effective recoveries of the questionnaires were 100%, the expert authority coefficients were 0.81, 0.81, 0.83, respectively, the coefficient of variation of expert consultation was 0.000-0.386, 0.000-0.300 and 0.000-0.250, respectively, the coordination degree of expert opinions in the third round of consultation was 0.679, 0.428 and 0.389 (all P<0.01). The formed training indexes of post competency of dental hygienist included 4 first-level indexes, 20 second-level indexes and 60 third-level indexes. Conclusions:The training index system of post competency of dental hygienist in this study is scientific, reliable, and practical, to provide reference for training and assessment of post competency of dental hygienist and objective basis for establishing the indexes system of dental nurse to dental hygienist in the future.

It experienced growth of the total amount of the published articles and citation. The USA had the largest number of research papers and China ranked the thirteenth, 10 journals including British Dental Journal published 53.25% of the SCI papers about oral nursing. Most articles were published on journals with impact factor ranging 1-2. The de Baat C research team was the most influential. The articles of oral nursing research focused on the oral health, care, quality of life, prevention, health, prevalence, oral hygiene, oral care, nursing, children, risk and so on. The analysis of burst terms found that the frontiers of oral nursing research focus on oral care, quality of life, health and so on.Conclusion:The hot-spot directions of oral nursing research are family oral care solution of specific people and the help of teledentistry for oral health care.
RESUMEN
Objective: To evaluate the global scientific output of PTG research and explore their hotspots、frontiers and trend from 2008 to 2018, using bibliometric methods. Methods: Based on web of science core collection database, the literature with keywords"Posttraumatic Growth or Post-traumatic Growth"in topic and time limit set between 2008 and 2018 were searched, and 1668 literature were accepted, using the CiteS pace to depict the hot keywords, cited references. Results: The subject domains of posttraumatic growth could be divided into traumatic event, growth and change, and influence factors of PTG. Keywords and references analysis indicated that the quality of life and breast cancer were the research hotspots, whereas physiological indicators and research tools of PTG were the frontiers. The United States of America ranked highest in the countries with most citations, and the leading institute was the North Carolina University. Publications were mainly in Journal of Traumatic Stress. Conclusion: Future research could focus on the exploration of PTG intervention program, such as qualitative research and longitudinal study to trace its dynamic change.
RESUMEN
Objective: To explore the impact of echocardiographic parameter of diastolic dysfunction (E/A) on the recurrence of atrial ifbrillation (AF) in patients after catheter ablation. Methods: We retrospectively studied 277 consecutive AF patients with circumferential pulmonary vein ablation (CPVA) in our hospital. According to E/A ratio, the patients were divided into 3 groups: Normal group, the patients with 0.752, n=21. The late AF recurrent rates were compared among different groups. The patients were divided into another 2 groups upon AF recurrence after CPVA: Recurrent group, n=57 patients with atrial arrhythmia lasted more than 30 seconds at 3 months after CPVA and Non-recurrent group, n=220. The clinical conditions were compared between 2 groups. Results: The patients were followed-up for (374 ± 276) days. The AF recurrent rate in Severe abnormal group was 33.3%, in Mild abnormal group was 23.5% and in Normal group was 18.5%, P>0.05. The E/A ratio in Recurrent group was 1.22 ± 0.54, in Non-recurrent group was 1.19 ± 0.49, P=0.653. Univariate analysis indicated that the risk factors for AF recurrence included LVEDD and gender, not E/A ratio (P=0.236). Cox multivariate analysis indicated that with adjusted gender, hypertension, diabetes, LVEDD and LVESD, abnormal E/A ratio was the predictor for late AF recurrence (HR 2.29, 95%CI 1.01-5.19, P=0.046). With further adjusted LVEDD and E/A, the severe abnormal E/A ratio was still the predictor for AF recurrence (HR 2.27, 95%CI 1.01-5.12, P=0.047). Conclusion: E/A ratio was the important predictor for AF recurrence in patients after CPVA.
RESUMEN
Objective To investigate the correlation between cerebrovascular disease risk and homocysteine (Hcy).Methods One hundred patients with cerebrovascular disease who confirmed by CT included 50 cases of cerebral hemorrhage (cerebral hemorrhage group) and 50 cases of cerebral infarction (cerebral infarction group).Eighty healthy person were selected as control group.The plasma Hcy was determined in all the subjects.The risk factors induced cerebral vascular disease were analyzed by multiple linear regression analysis and the correlation between cerebrovascular disease risk and Hcy was investigated.Results The plasma Hcy in cerebral hemorrhage group and cerebral infarction group was higher than that in control group[(19.87 ± 5.23),(19.64 ± 4.98) μ mol/L vs.(14.54 + 3.58) μ mol/L,P ＜ 0.05].There was no significant difference in the plasma Hcy between cerebral hemorrhage group and cerebral infarction group (P ＞ 0.05).Multiple linear regression analysis showed that Hcy was independently associated with cerebral hemorrhage and cerebral infarction (P ＜ 0.05).Conclusion The plasma Hcy in patients with cerebrovascular disease is higher than that in the normal population,and Hcy is independently associated with cerebrovascular disease.The plasma Hcy has an important role for prediction and diagnosis of cerebrovascular disease.
