Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Zhishi Xiebai Guizhitang is a classical prescription for the treatment of chest impediment with the method of warming Yang. It is included in the Catalogue of Ancient Classical Prescriptions issued by the National Administration of Traditional Chinese Medicine （First Batch）， with the effect of activating Yang， dissipating mass， moving Qi and resolving phlegm. Its main symptoms include chest fullness and pain， or even chest pain radiating to the back， wheezing， coughing， shortness of breath， and Qi reversal from the hypochondrium. In modern traditional Chinese medicine， Zhishi Xiebai Guizhitang is clinically used in the treatment of cardiovascular system， digestive system， respiratory system and other diseases， among which coronary heart disease， unstable angina pectoris， myocardial infarction， sinus bradycardia and other cardiovascular diseases have particularly significant effects. This paper reviewed the pharmacological studies of Zhishi Xiebai Guizhitang in the past 10 years. The results showed that each single medicine and the whole prescription alleviated the above cardiovascular diseases to a certain extent， with the pharmacological effects of improving intravascular environment， myocardial ischemia， myocardial ischemia-reperfusion injury， and myocardial hypoxia， anti-inflammation， plaque stabilisation， etc.， and the pharmacological mechanism involved the regulation of relevant active substances in vivo as well as related signaling pathways and ion channels， mainly including thromboxane B₂ （TXB₂）， prostacyclin I₂（PGI₂） and phosphatidylinositol 3-kinases/protein kinase B/endothelial nitric oxide synthase （PI3K/Akt/eNOS） signaling pathways， and ATP-sensitive potassium channels. In addition， the relationship between the pharmacological effects of some single medicines and transient receptor potential ankyrin 1 （TRPA1） has been reported that TRPA1 is a key to understanding the mechanism of Zhishi Xiebai Guizhitang in treating cardiovascular diseases， which is worth of further study.

Objective:To evaluate the medium-term clinical and hemodynamic outcomes of percutaneous pulmonary valve implantation (PPVI) using a domestic Venus-P self-expanding valve in the treatment of severe pulmonary regurgitation after Tetralogy of Fallot (TOF).Methods:Retrospective study.From December 2017 to December 2020, 13 TOF patients with (17.8±4.7) years old and (50.2±12.3) kg underwent PPVI using the Venus-P self-expanding valve in the Department of Children′s Heart Center, Zhengzhou University People′s Hospital were recruited.The mean valve size was (31.9±3.1) mm.All patients received the transannular patch surgery and developed severe pulmonary regurgitation.After PPVI, 13 patients were followed up for at least 12 months.The operation-related complications, improvement of valve and heart function and the durability and reintervention of the Venus-P self-expanding valve were analyzed.The right ventricular end-diastolic volume index (RVEDVi) before and after operation was compared by the paired t-test, and the New York Heart Association (NYHA) class was compared by the paired Wilcoxon signed rank sum test. Results:PPVI was successfully performed in all 13 patients without death.At 6 months post-PPVI, cardiac magnetic resonance imaging findings showed that RVEDVi was significantly reduced[(145.7±9.6) mL/m 2vs.(100.2±12.2) mL/m 2, P<0.05], and the NYHA class was significantly improved ( P<0.05). One patient presented moderate pulmonary valve regurgitation at 12 months postoperatively.No vegetation was found on echocardiography, and blood culture was negative in this case.Six patients did not have postoperative pulmonary valve regurgitation, and the remaining presented mild or less pulmonary regurgitation.One patient had sudden ventricular tachycardia on the 6 th day postoperatively, which was converted to sinus rhythm after synchronous electrocardiography.Only one case underwent appendectomy 7 months after operation due to acute appendicitis, and the remaining did not require valve-related reintervention after implantation.During the follow-up for (22.8±8.0) months, no patients had perivalve leakage, stent migration and rupture.Complications like embolization and coronary artery compression were not reported. Conclusions:PPVI using the Venus-P self-expanding valve is safe and effective in patients with severe pulmonary valve regurgitation after TOF surgery, showing an acceptable medium-term follow-up outcome.Studies with a large sample size and long follow-up period are still needed to validate our findings.

Objective:To explore the association between parental socioeconomic status (SES) and preschoolers’ consumption of sugar-sweetened beverages (SSB).Methods:In June 2018, all preschoolers from 15 kindergartens were selected from the jurisdiction of Education Commission in Dongcheng District of Beijing by using an equal-proportion stratified cluster sampling method in the study. A self-designed questionnaire was used to investigate the parents of preschoolers to obtain the basic information of preschoolers and parents, the consumption situation of preschoolers’ sugar-sweetened beverages and the perception of parents to SSB. A tatol of 3 217 preschoolers were finally included in the analysis. A generalized structural equation model was used to analyze the relationship between preschoolers' consumption of sugar-sweetened beverages and their parents' socioeconomic status and the mediating effect of their cognition of sugar-sweetened beverages. The size of mediating effect was estimated by using deviation correction non-parameter percentile Bootstrap method.Results:The age of 3 217 preschoolers was (4.23±0.67) years, of which 52.6% ( n=1 692) were boys, and 77.62% ( n=2 497) were SSB consumers. Among the parents of 3 217 preschoolers, fathers and mothers accounted for 24.90% ( n=801) and 75.10% ( n=2 416), and the M ( P25, P75) scores of SES were 66.7 (62.5, 69.5) and 69.5 (64.6, 71.4), respectively. The proportion of parents who took the initiative to learn about their children's consumption of SSB, lacked confidence in restricting preschooler's consumption of SSB and read nutrition labels before purchasing food was 74.08% ( n=2 383), 82.90% ( n=2 667) and 36.24% ( n=1 166), respectively. The generalized structural equation model showed that after adjusting for preschoolers’ gender, age, body mass index (BMI) of preschoolers and their parents, preschoolers’ consumption of SSB was negatively associated with their parents’ SES score [path coefficient (95% CI):-4.69×10 -2 (-6.56×10 -2,-2.69×10 -2) ]. The mediating effect of parents’ perception of SSB consumption could explain 48.71% of the total effect [path coefficient (95% CI):-2.28×10 -2 (-3.54×10 -2, -1.10×10 -2)]. Conclusion:The consumption of SSB in preschoolers is negatively associated with their parent’s SES, and this relationship is partially mediated by parent’s perception of SSB consumption.
