Zhigancao Tang， derived from the Treatise on Cold Damage，is a classic and renowned formula for treating "intermittent and irregular pulse， and palpitations of the heart". It has an exquisite formulation. By replenishing Qi， nourishing Yin， activating Yang， and restoring the pulse， it achieves the dual supplementation of Yin and Yang， and the simultaneous treatment of Qi and blood. With the practical expansion by practitioners over successive dynasties， the application scope of this formula has been continuously expanding， extending from traditional cardiovascular diseases to diseases of multiple systems， fully reflecting the theoretical characteristics of traditional Chinese medicine （TCM） of "treating different diseases with the same method". Modern research shows that Zhigancao Tang not only has a remarkable curative effect on cardiovascular diseases but is also widely applied to diseases of the respiratory， nervous， digestive， endocrine， oncologic， gynecologic， and otorhinolaryngologic systems， demonstrating its interdisciplinary clinical application value. At the same time， research on the mechanism of action of Zhigancao Tang is also continuously deepening. The mechanisms by which it treats diseases involve multiple aspects， including anti-arrhythmic effects， myocardial protection， anti-fibrosis， antioxidative stress and anti‑inflammatory effects， regulation of glucose and lipid metabolism， enhancing hematopoietic function， and improving hemorheology. These mechanisms work synergistically to jointly regulate the physiological functions of the body and play a role in treating diseases. However， there are still some deficiencies in current research. For example， the sample size of some clinical trials is small， most of the mechanism studies are based on animal models or in vitro experiments， there is insufficient high-quality evidence from clinical trials， the composition of the compound formula is complex， and the pharmacodynamic material basis and the rules of compatibility still need to be deeply analyzed. By consulting relevant literature， this article systematically summarizes the modern clinical application and action mechanism of Zhigancao Tang， aiming to provide new ideas for its subsequent in-depth research and clinical application， promote the integrated development of classic TCM formulas and modern medicine， and further explore its great potential in clinical treatment.

Objective: To evaluate the application effect of oral health management program based on behavior change wheel (BCW) theory, so as to provide a reference for improving children s awareness of oral self management and the development of healthy oral behaviors. Methods: A total of 120 children aged 5-6 from 2 kindergartens in Yubei District in Chongqing City, selected by convenience sampling method from September 2023 to March 2024, were divided into a experimental group and a control group (60 each). Children in the experimental group were given an oral health education programme based on BCW theory (promoted health awareness, cultivated healthy behavior ability, strengthened awareness and ability, and provided opportunitiess) on the basis of conventional oral health education, and children in the control group were given conventional oral health education; data were collected before and 3 months after the intervention, respectively. Comparisons between groups were made using the Mann-Whitney U test and χ 2 test. Results: Before intervention, there were no significant differences in plaque index [2.00(1.00,2.00), 2.00(1.00,2.00)] and the number of filled teeth [0.00(0.00,1.00), 0.00( 0.00 ,1.00)] between the experimental group and the control group ( Z=-0.88, -0.42, P >0.05). After intervention, the plaque index of the experimental group [1.00(0.00,1.00)] was lower than that of the control group [1.00(0.25,2.00)] and before intervention, and the number of filling teeth in the experimental group [1.00(0.00,2.00)] was higher than that of the control group [1.00(0.00,1.00)] and before intervention, the differences were statistically significant ( Z =-3.14, -5.48; -2.08, -3.02, P <0.05). Before intervention, there were no significant differences in oral health behavior report rate and oral health knowledge mastery rate between the two groups ( χ 2=0.30-0.91, 0.15-1.43, P > 0.05 ). After intervention, the report rates of health tooth brushing (method, frequency and duration) and preventive behavior (using fluoride toothpaste, pit and fissure sealing prevention and fluoride application prevention) in the experimental group were better than those in the control group and before intervention, and the differences were statistically significant ( χ 2=4.88-9.38, 9.13- 22.63 , P <0.05). The mastery rates of oral health knowledge in the experimental group were better than that in the control group, and the differences were statistically significant ( χ 2=4.62-8.54, P <0.05). Conclusion Oral health management programs based on the BCW theory are more conducive to improving children s oral hygiene, as well as enhancing children s basic oral knowledge and promoting the development of oral health behaviors.

Objective:To understand the prevalence of occasional hypertension in preschool children in three provinces in the middle and lower reaches of the Yangtze River in China, and analyze the relationship between their sleep status and occasional hypertension.Methods:From October to November 2017, a total of 24 842 preschool children from 109 kindergartens in 11 cities in Hubei, Anhui and Jiangsu provinces were selected by intentional sampling method. A self-made questionnaire was used to collect basic information about the subjects, and the sleep status data was collected by the Children′s Sleep Habits Questionnaire. Physical examinations were performed on the subjects, and height, weight and blood pressure were measured on-site. The difference in occasional hypertension detection rate among preschool children with different characteristics was compared, and the correlation between sleep status and occasional hypertension detection rate was analyzed by the multivariate logistic regression model.Results:The age of the subjects was (4.4±1.0) years, including 12 729 boys (51.2%). The prevalence of occasional hypertension was 31.8% (7 907/24 842). The prevalence of occasional hypertension among preschool children in three provinces of the middle and lower reaches of the Yangtze River was 31.8%. There were statistically significant differences in the detection rate of occasional hypertension among preschool children of different genders, age groups, family residence, family economic status and parents′ education level (all P values<0.05). The detection rate of occasional hypertension in children with less than 10 hours of sleep was higher than those with sufficient sleep, and the difference was statistically significant ( P<0.05). The results of multivariate logistic regression analysis showed that after adjusting for factors such as gender, age, family residence, family economic status, parental education level, parental smoking history, and physical constitution, the ORs (95% CI) for less than 10 hours of sleep, turning on the lights while sleeping, and poor sleep quality were 1.09 (1.03-1.15), 1.17 (1.07-1.28) and 1.04 (0.91-1.18), respectively, compared with the corresponding reference group. Conclusion:The detection rate of occasional hypertension is high in preschool children in the middle and lower reaches of the Yangtze River and there is a positive correlation between insufficient sleep and turning on the light when sleeping and occasional hypertension in preschool children.

Objective:To investigate the imaging quality of CBCT under different exposure parameters and the relationship between subjective and objective evaluation.Methods:CBCT scanners of 6 different suppliers[3D Accuitomo(Morita),i-mCAT(Kavo),5G(NewTom),Smart3D(Beijing Langshi),DCT Pro(Vatech),Vgi(NewTom)]were used to scan the spatial resolution models and head simulators under typical exposure conditions(different device with different tube voltage and current for exposure).The visibility of SedentexCT IQ phantom and anatomical structures generated by different CBCT scanners were compared.For objective evaluation,7 professional evaluators scored CBCT imaging qualities.For subjective evaluation,the resolution(LP/mm)of the images were com-pared among the devices.Results:No significant difference was found by 7 evaluators either intra or inter of the teams.By objective e-valuation,the score of NewTom 5G was 2,that of i-CAT was 5 and that of the others was 4.By subjective evaluation,the LP/mm of i-CAT was 1.8,that of Smart3D was 2.0 and that of the others was 1.0-1.7.The subjective evaluation of image quality obtained un-der different tube voltages and tube currents were significantly different.Conclusion:The subjective and objective evaluations of image quality are approximately consistent.The difference of the subjective image quality may be produced by the different tube voltage and current for exposure.

Objective:To analyze the association between waist circumference (WC) and ischemic stroke (IS).Methods:The data for the present study were from the prospective cohort study of China Kadoorie Biobank in Qingdao. Using baseline information and IS events of the participants, the Cox proportional hazard regression model and restricted cubic spline (RCS) were used to analyze the association between WC and IS.Results:A total of 33 355 participants were included in the study, with 302 008.88 person-years of follow-up. A total of 1 093 new cases of IS were observed. Multivariate Cox proportional hazard regression model analysis showed that compared to the respondents with normal WC (male <85.0 cm, female <80.0 cm), respondents with excessive WC (male ≥85.0 cm, female ≥80.0 cm) had a 78% higher risk of IS incidence [hazard ratio( HR)=1.78, 95% CI: 1.51-2.10], and the risk increased by 72% ( HR=1.72, 95% CI: 1.40-2.12) and 83% ( HR=1.83, 95% CI: 1.40-2.39) in men and women. According to the RCS, the increase in WC and the risk of IS showed an "S" trend of nonlinear dose-response relationship. Conclusions:The risk of IS would increase with the WC. Keeping a normal WC is important for preventing IS.

Objective:To explore the adaptive index of pulmonary rehabilitation self-efficacy and its influencing factors in elderly patients with chronic obstructive pulmonary disease (COPD), and to provide reference for formulating and implementing effective intervention strategies.Methods:This was a cross-sectional study. The convenience sampling method was used to select 279 elderly COPD patients hospitalized in the Department of Respiratory and Critical Care Medicine of Xinjiang Uygur Autonomous Region People′s Hospital from March 2023 to June 2023. They were investigated by the general information questionnaire, Chinese version of Pulmonary Rehabilitation Adapted Index of Self-Efficacy, Social Support Scale and Frailty Phenotype. Multiple linear stepwise regression analysis was used to explore the influencing factors of pulmonary rehabilitation self-efficacy in elderly patients with COPD.Results:The age distribution of 279 elderly COPD patients was 117 cases aged 60-69, 102 cases aged 70-79, and 60 cases aged ≥ 80, including 134 males and 145 females. The total score of Chinese version of Pulmonary Rehabilitation Adapted Index of Self-Efficacy in elderly COPD patients was (24.95 ± 5.20) points, and the highest dimension of item mean score was exercise self-efficacy (1.99 ± 0.62) points, while the lowest mean score was strain capacity (1.88 ± 0.44) points. Multiple linear regression analysis showed that educational level, pulmonary function grade, COPD assessment test (CAT) score, social support level and frailty were influencing factors of pulmonary rehabilitation self-efficacy in elderly COPD patients ( t values were - 9.01-3.36, all P<0.05), accounting for 43.4% of the total variation. Conclusions:The self-efficacy adaptation index of pulmonary rehabilitation in the elderly patients with COPD is at the middle-lower level. Health care providers should fully understand the relevant influencing factors, and establish targeted and individualized pulmonary rehabilitation intervention strategies on these basis to maximize the subjective initiative of patients.
