Objective: To explore the interaction effects and possible sex differences in childhood emotional overeating and polygenic influences on adolescent pubertal timing and tempo. Methods: In March 2016 (T0), all participants were recruited from grades 1 to 3 from two primary school of Bengbu, Anhui Province using cluster sampling, and follow up surveys were conducted once per year (T1, T2, T3). Emotional overeating was assessed at T1 and pubertal development was assessed annually (breast Tanner stage in girls and testicular volume in boys). The nonlinear growth model was used to estimate pubertal timing and tempo. Polygenic risk scores were calculated based on 17 SNPs for early pubertal timing. Hierarchical linear regression was performed to examine the interaction effects between childhood emotional overeating and polygenic risk scores on pubertal timing and tempo. Results: The complete data of 896 children were analyzed, including 373 boys (41.60%) and 523 girls (58.40%). A total of 203 (22.7%) children reported emotional overeating behavior at T1. After adjusting for several variables including early life adversity, delivery mode, and birthweight, only emotional overeating was associated with accelerated pubertal tempo among girls with a high genetic risk (B=0.19, 95%CI=0.07~0.32， P<0.01), although there was no association with pubertal timing (B=0.14, 95%CI=-0.12~0.41，P=0.28). In girls with a low genetic risk and boys, no evidence was found to support interaction effects between childhood emotional overeating and polygenic influences on pubertal timing and tempo (P＞0.05). Conclusion Emotional overeating was associated with a faster pubertal tempo in girls who had a high genetic risk of early pubertal development.

Objective: To evaluate the development trajectory of sugar-sweetened beverage (SSB) intake in childhood, and to explore the influence of different SSB intake patterns on childhood obesity. Methods: In 2016, a follow-up cohort study was carried out in two primary schools in Bengbu, Anhui Province. Three annual follow-ups were conducted in 1 263 children at baseline, and 997 children were included in the final analysis. Parental and student questionnaires were used to obtain basic information related to the children s consumption of SSBs. A group-based trajectory model (GBTM) was applied to classify the development trajectory of SSB intake patterns in childhood. Multiple linear regression analyses were performed to assess the correlation between different SSB intake patterns and childhood obesity. Results: GBTM identified four childhood SSB intake patterns, namely, the "persistently-low group (n=822), “decreasing-after-increasing” group (n=20), “gradually-decreasing” group (n=106), and “increasing” group (n=49). In the decreasing-after-increasing group and the gradually-decreasing group, baseline BMI levels and BMI levels obtained at the three follow-ups were significantly higher than those observed in the persistently-low group (F=6.26, 5.90, 5.99, 5.87, P<0.01). There were sex differences in the association between SSB intake patterns and the children s BMI levels. Among girls, after adjusting for confounding factors, the gradually decreasing group increased by 1.20 kg/m 2(B=1.20，95%CI=0.25-2.15, P=0.01) when compared with the persistently low group at the third follow-up. Among boys, no statistically significant association was found between SSB intake patterns and BMI levels (P>0.05). Conclusion Sex differences were observed with respect to the association between SSB intake patterns and obesity in children. Girls with a higher SSB intake had a significantly increased risk of obesity. Further studies are needed to explore the physiological mechanisms underlying sex differences, to provide the theoretical basis for developing intervention programs to prevent childhood obesity.

BACKGROUND:In recent years,epidemiological studies have shown that sleep patterns are risk factors for osteoarthritis,but the causal relationship between sleep characteristics and osteoarthritis remains unknown. OBJECTIVE:To investigate the causal relationship between seven sleep phenotypes and osteoarthritis,thereby providing a theoretical foundation for clinical prevention and intervention of osteoarthritis. METHODS:Seven sleep-related features,namely sleep duration,wake-up time,daytime napping,morning/evening preference,snoring,insomnia,and hypersomnia,were selected from published genome-wide association studies.Instrumental variables for these sleep-related features were extracted.Instrumental variables for knee osteoarthritis and hip osteoarthritis were obtained from publicly available genome-wide association studies.Causal relationships between sleep characteristics and outcome risks were evaluated using two-sample and multivariable Mendelian randomization analyses.The inverse variance weighted method was employed as the primary Mendelian randomization approach.Various methods,including weighted median,weighted mode,Mendelian randomization-Egger regression,Mendelian randomization pleiotropy-residual sum and outlier,were utilized to detect and correct for the presence of pleiotropy. RESULTS AND CONCLUSION:The results of the inverse variance-weighted method in the two-sample Mendelian randomization study revealed a detrimental causal association between the duration of sleep and the incidence risk of knee osteoarthritis[odds ratio(OR)=0.621,95%confidence interval(CI):0.470-0.822,P=0.001].Concurrently,insomnia displayed a positive causal connection with hip osteoarthritis risk(OR=2.016,95%CI:1.249-3.254,P=0.005).Sensitivity analysis affirmed the robustness of these causal relationships,and Mendelian randomization-Egger intercept analysis found no evidence of potential horizontal pleiotropy(knee osteoarthritis:P=0.468,hip osteoarthritis:P=0.551).Moreover,the results from the multivariable Mendelian randomization analysis showed that the causal association between insomnia and hip osteoarthritis lacked statistical significance(P=0.715).In contrast,sleep duration exhibited a direct negative causal relationship with the incidence risk of knee osteoarthritis(OR=0.526,95%CI:0.336-0.824,P=0.005).Reverse Mendelian randomization analysis indicated that knee osteoarthritis did not influence sleep duration(P=0.757).These findings indicate a negative correlation between sleep duration and incidence risk of knee osteoarthritis,suggesting that correcting insufficient sleep might mitigate the incidence risk of knee osteoarthritis.

ObjectiveTo analyse the clinical characteristics of different traditional Chinese medicine （TCM） syndromes in patients with heart failure based on information from electronic medical record. MethodsA cross-sectional study was conducted to collect clinical data of all inpatients with heart failure in the Department of Cardiology， Affiliated Hospital of Liaoning University of Traditional Chinese Medicine from January 1， 2019 to December 31， 2020. A database of clinical TCM data was established to explore the characteristics of clinical data of basic information， syndromes and syndrome element types， and biochemical indexes. The distribution of TCM syndromes and syndrome elements in heart failure patients were also analysed， and the basic information and biochemical indexes of the patients with top 7 different TCM syndrome types were compared. ResultsA total of 1676 inpatients with heart fai-lure were included. The top 7 TCM syndromes of heart failure were syndrome of phlegm turbidity and blood stasis （477 cases， 28.46%）， syndrome of qi deficiency and blood stasis （439 cases， 26.19%）， syndrome of qi deficiency and blood stasis with water retention （274 cases， 16.35%）， syndrome of yang deficiency with water retention （145 cases， 8.65%）， syndrome of qi and yin deficiency （104 cases， 6.21%）， syndrome of qi and yin deficiency with blood stasis （80 cases， 4.77%）， syndrome of heart yang deficiency （59 cases， 3.52%）. Among the 1676 patients， 6 syndrome elements accounted for more than 5%. Blood stasis accounted for the highest proportion of TCM syndrome element type （1292 cases， 77.09%）， followed by qi deficiency （919 cases， 54.83%）， phlegm （498 cases， 29.71%）， water retention （434 cases， 25.89%）， yang deficiency （215 cases， 12.82%） and yin deficiency （191 cases， 11.40%）. Among the 1676 patients， 1308 cases of acute heart failure mainly showed syndrome of phlegm turbidity and blood stasis （386 cases， 29.51%）， and 368 of chronic heart fai-lure mainly showed syndrome of qi deficiency and blood stasis （118 cases， 32.07%）. Patients with syndrome of phlegm turbidity and blood stasis had the shortest disease duration of 0.3 months， while those with syndrome of heart yang deficiency had the longest disease duration of 15 months. The proportion of syndrome of phlegm turbidity and blood stasis was the highest in patients with heart failure combined with coronary artery disease， the proportion of syndrome of qi deficiency and blood stasis with water retention was the highest in patients with heart failure combined with atrial fibrillation， and the proportion of patients with syndrome of qi deficiency and blood stasis with water retention and syndrome of yang deficiency with water retention in those applying diuretics during the hospital stay was the highest with more than 86%. The different 7 TCM syndromes showed statistically difference in patients with complications including coronary artery disease， old myocardial infarction， atrial fibrillation， pre and post-admission medication usage including intravenous vasodilators， cardiac stimulants， diuretics， and level of blood chloride， blood urea， blood creatinine， blood bicarbonate， blood albumin， and blood total bilirubin （P＜0.05）. ConclusionThe most common TCM syndromes in patients with heart failure are syndrome of phlegm turbidity and blood stasis and syndrome of qi deficiency and blood stasis. Different TCM syndromes have different characteristics in gender， disease complications， medication before and after admission， and blood indexes.

Knee osteoarthritis （KOA） is a common degenerative joint disease characterized primarily by the degeneration and damage of knee joint cartilage， accompanied by osteophyte formation and inflammation. In recent years， the prevalence of KOA has been increasing globally， significantly impacting the quality of life patients. However， the pathogenesis of KOA remains not fully understood， and current treatment methods are limited. Therefore， finding new therapeutic strategies is a research hotspot. Previous studies have found that the onset of KOA is related to abnormal mitochondrial regulation. Mitochondria， functioning as secondary messengers， play crucial roles in cellular respiration， reactive oxygen species （ROS） generation， and adenosine triphosphate （ATP） production through oxidative phosphorylation. Mitochondrial quality control is a pivotal mechanism for maintaining the morphology， quantity， and quality of mitochondria. The connection between mitochondrial quality control and the pathogenesis of KOA involves several factors， such as mitochondrial oxidative stress， mitophagy， imbalances in mitochondrial biogenesis， abnormal mitochondrial dynamics （fission and fusion）， and dysregulation of calcium ions. Metabolic abnormalities in the body lead to mitochondrial structural damage， which in turn contributes to the onset and progression of KOA. Traditional Chinese medicine （TCM） has made some progress in intervening in mitochondrial quality control， employing multi-faceted， multi-pathway， and multi-target strategies to treat KOA. Several studies have shown that mitochondrial quality control may be one of the therapeutic targets of TCM in treating KOA. However， there is currently a lack of comprehensive reviews summarizing the TCM interventions in mitochondrial quality control for treating KOA. This paper systematically reviewed the research progress in TCM treatment of KOA based on five aspects of mitochondrial quality control， aiming to provide a theoretical basis for the clinical prevention and treatment of KOA.

OBJECTIVE To conduct a reevaluation of the systematic review （SR）/meta-analysis on the use of Xianling gubao capsules （XLGBC） for knee osteoarthritis （KOA）， and provide evidence-based support for the clinical use of the drugs. METHODS Computerized searches including CNKI， Wanfang Data， VIP， China Biomedical Literature Database， the Cochrane Library， PubMed， Embase and Web of Science were conducted to collect systematic reviews （SR） or meta-analyses of XLGBC for the treatment of KOA from the inception to May 31st， 2024. The report quality， methodological quality， risk of bias and evidence quality were assessed using the PRISMA 2020 statement， AMSTAR 2 scale， ROBIS tool and GRADE tool， respectively. A comprehensive quality analysis of the quantitative results from the SR/meta-analysis was also performed. RESULTS A total of five SR/meta-analyses were included. The evaluation results based on the PRISMA 2020 statement showed that one study report was relatively complete （21 points）， while four studies had deficiencies （18-20 points）. The assessment using the AMSTAR 2 scale indicated that the methodological quality of all five studies was rated as very low. According to the ROBIS tool evaluation， the risk of comprehensive bias in all five studies was classified as high. GRADE tool evaluation revealed that among 49 outcome indicators， 5 （10.2%） were rated as moderate-quality evidence （10.2%）， 12 as low-quality evidence （24.5%）， and 32 as very low-quality evidence （65.3%）. The results of comprehensive quality analysis showed that the clinical efficacy， visual analogue scale score， pain relief time， comprehensive indexes of knee joint function， the levels of inflammatory factors and the incidence of adverse events in patients with XLGBC combined with conventional treatment were significantly better than conventional treatment alone （P＜0.05）. CONCLUSIONS Compared with conventional treatment， XLGBC in combination with conventional treatment for KOA may have some efficacy and safety advantages. However， due to the low quality of evidence for the outcome indicators included in the studies， the conclusions should be interpreted with caution.
