Objective: To investigate the mediating role of vaccine literacy between vaccine knowledge and vaccine hesitancy and the moderating role of parental education level, so as to provide references for adjusting vaccination strategies. Methods: From May to December 2024, a stratified random sampling method was used to select 10 community hospitals in Guiyang and Zunyi City, Guizhou Province. A total of 1 401 parents of children aged 0-6 years were surveyed regarding their socio demographic characteristics, vaccine knowledge, vaccine literacy, and vaccine hesitancy levels. Data were analyzed using common method bias tests, Spearman correlation analysis, mediation and moderation effects tests. Results: The mean score for vaccine knowledge, vaccine literacy and vaccine hesitancy were (2.96±1.11, 14.25±2.64, 39.12±4.93) among the 1 401 participants. Mediating effect analysis showed that both parental vaccine knowledge ( β =1.28, 95% CI =1.08-1.49) and vaccine literacy ( β =0.75, 95% CI =0.66-0.84) positively predicted vaccine hesitancy (both P <0.01). Meanwhile, vaccine literacy accounted for 28.1% of the total effect of mediation between knowledge and vaccine hesitancy. In the moderated effects analysis, education level positively predicted vaccine literacy ( β =0.40, 95% CI =0.24-0.57), and education level moderated the pathway of vaccine knowledge on vaccine hesitancy ( β = 0.28 , 95% CI =0.05-0.52) (both P <0.01). Conclusions Vaccine literacy partially mediates the relationship between vaccine knowledge and vaccine hesitancy. Parental education level positively moderates the prediction of vaccine knowledge on vaccine hesitancy score.

ObjectiveTo investigate the effect and mechanism of total saponins from Panax japonicus （TSPJ） on white adipose tissue （WAT） browning/brown adipose tissue （BAT） activation in C57BL6/J male mice fed on a high-fat diet （HFD）. MethodThirty-two C57BL6/J male mice （8-week-old） were randomly divided into a normal group， a model group， a low-dose TSPJ group， and a high-dose TSPJ group. The mice in the low-dose and high-dose TSPJ groups were given TSPJ for four months by gavage at 25， 75 mg·kg^-1·d^-1， respectively， and those in the other groups were given 0.5% sodium carboxymethyl cellulose （CMC-Na） accordingly. After four months of feeding， all mice were placed at 4 ℃ for acute cold exposure， and the core body temperature was monitored. Subsequently， all mice were sacrificed， and BAT and inguinal WAT （iWAT） were separated rapidly to detect the corresponding indexes. Hematoxylin-eosin （HE） staining was used to observe the morphological changes in each group. The effect of TSPJ on the mRNA expression of uncoupling protein 1 （UCP1）， fatty acid-binding protein 4 （FABP4）， cytochrome C （CytC）， PR domain-containing protein 16 （PRDM16）， elongation of very long chain fatty acids protein 3 （ELOVL3）， peroxisome proliferator-activated receptor γ （PPARγ）， and peroxisome proliferator-activated receptor-γ coactivator-1α （PGC-1α） in iWAT and BAT was detected by Real-time polymerase chain reaction （Real-time PCR）. Western blot was also used to detect the protein expression of UCP1， PRDM16， PPARγ， and PGC-1α in BAT and iWAT of each group. The effect of TSPJ on UCP1 expression in BAT and iWAT was detected by immunohistochemistry. Result① Compared with the model group， TSPJ could decrease the body weight and proportions of iWAT and BAT in the HFD-induced mice （P<0.05， P<0.01）. ② The body temperature of mice in the model group decreased compared with that in the normal group in the acute cold exposure tolerance test （P<0.05）. The body temperature in the high-dose TSPJ group increased compared with that in the model group （P<0.01）. ③ Compared with the normal group， the model group showed increased adipocyte diameter in iWAT and BAT and decreased number of adipocytes per unit area. Compared with the model group， the TSPJ groups showed significantly reduced cell diameter and increased number of cells per unit area， especially in the high-dose TSPJ group. ④ Compared with the normal group， the model group showed decreased mRNA expression of FABP4， UCP1， CytC， PRDM16， ELOVL3， PGC-1α， and PPARγ in adipose tissues of mice （P<0.05， P<0.01）. Compared with the model group， after intervention with TSPJ， the mRNA expression was significantly up-regulated （P<0.05， P<0.01）. ⑤ Compared with the normal group， the model group showed decreased protein expression of UCP1， PRDM16， PPARγ， and PGC-1α in adipose tissues of mice （P<0.05， P<0.01）. Compared with the model group， after intervention with TSPJ， the protein expression increased significantly （P<0.05， P<0.01）. ConclusionTSPJ could induce the browning of iWAT/BAT activation and enhance adaptive thermogenesis in obese mice induced by HFD. The underlying mechanism may be attributed to the activation of the PPARγ/PGC-1α signaling pathway.

BACKGROUND AND AIM: Remnant cholesterol (remnant-C) mediates the progression of major adverse cardiovascular events. It is unclear whether remnant-C, and particularly cumulative exposure to remnant-C, is associated with nonalcoholic fatty liver disease (NAFLD). This study aimed to explore whether remnant-C, not only baseline but cumulative exposure, can be used to independently evaluate the risk of NAFLD. METHODS: This study included 1 cohort totaling 21,958 subjects without NAFLD at baseline who underwent at least 2 repeated health checkups and 1 sub-cohort totaling 2,649 subjects restricted to those individuals with at least 4 examinations and no history of NAFLD until Exam 3. Cumulative remnant-C was calculated as a timeweighted model for each examination multiplied by the time between the 2 examinations divided the whole duration. Cox regression models were performed to estimate the association between baseline and cumulative exposure to remnant-C and incident NAFLD. RESULTS: After multivariable adjustment, compared with the quintile 1 of baseline remnant-C, individuals with higher quintiles demonstrated significantly higher risks for NAFLD (hazard ratio [HR] 1.48, 95%CI 1.31-1.67 for quintile 2; HR 2.07, 95%CI 1.85-2.33 for quintile 3; HR 2.55, 95%CI 2.27-2.88 for quintile 4). Similarly, high cumulative remnant-C quintiles were significantly associated with higher risks for NAFLD (HR 3.43, 95%CI 1.95-6.05 for quintile 2; HR 4.25, 95%CI 2.44-7.40 for quintile 3; HR 6.29, 95%CI 3.59-10.99 for quintile 4), compared with the quintile 1. CONCLUSION Elevated levels of baseline and cumulative remnant-C were independently associated with incident NAFLD. Monitoring immediate levels and longitudinal trends of remnant-C may need to be emphasized in adults as part of NAFLD prevention strategy.

Objective:To investigate whether long non-coding RNA(lncRNA) AW112010 can improve insulin resistance in aging adipocytes through the miR-204/POU2F2 signaling pathway.Methods:In vivo experiment: C57BL/6 mice were divided into young control group(4 months old) and aging model group(18 months old) based on body weight. The expression levels of AW112010, miR-204-5p, POU2F2, aging related indicators(p16, p21), and insulin signaling pathway genes [insulin receptor(INSR), insulin receptor substrate 1(IRS1), phosphatidylinositol kinase(PI3K), protein kinase B(AKT)] in epididymal adipose tissue were detected using real-time fluorescence quantitative PCR(RT-qPCR) and Western blotting. In vitro experiment: Using adriamycin(ADR) to induce 3T3-L1 aging adipocyte model, β-gal staining was used to observe cellular senescence, and miR-204 inhibitor and miR-204 mimic small interfering RNA were successfully constructed and transfected into 3T3-L1 adipocytes. Results:RT-qPCR and Western blot results showed that compared with the young group, the expression of AW112010 in the adipose tissue of aging mice was increased, while the expression of miR-204-5p was decreased. The expressions of POU2F2, p16, and p21 in the adipose tissue of aging mice were increased, while the expressions of INSR, IRS1, PI3K, GLUT4 mRNA and protein were decreased. The β-gal stainging results showed that the number of 3T3-L1 senescent adipocytes induced by ADR was significantly increased, and the expression levels of AW112010, POU2F2, p16, and p21 in ADR-induced senescent adipocytes were increased compared with the control group, while the expression levels of miR-204-5p, INSR, IRS1, PI3K, GLUT4 were decreased, and remaining glucose in the culture medium was increased. Compared with control, overexpression of miR-204 resulted in decreased expressions of aging indicators p16, p21, and target gene POU2F2 while the expressions of INSR and GLUT4 were increased.Conclusion:Upregulation of lncRNA AW112010 in adipocytes of aging mice may induce insulin resistance by targeting miR-204-5p/POU2F2/IRS1.

Selenium is one of the essential trace elements in human body, which plays an important role in regulating human growth and physiological function. Selenium deficiency can lead to a variety of diseases, such as Kashin-Beck disease, Keshan disease, thyroid disease and increase the incidence of cancer. It was found that serum selenium level decreased significantly in patients with leukemia, and it was associated with poor prognosis. Selenium can play a dual role in the treatment of leukemia: on the one hand, it can play a synergistic anti-leukemia effect with chemotherapy drugs, and on the other hand, it can reduce the side effects of chemotherapy drugs. In recent years, nano-selenium, as a new type of elemental selenium, has higher bioavailability, stronger bioactivity and lower toxicity than organic and inorganic selenium. This article reviews the progress of selenium and its compounds in leukemia.

Ferroptosis is a form of iron-dependent cell death caused by a disorder of iron lipid metabolism.Its mechanism mainly includes lipid metabolism and iron metabolism,which are complicated and strictly regulated by various metabolic and signaling pathways.Current studies have shown that ferroptosis is associated with cancer,atherosclerosis,and neurological diseases.Traditional Chinese medicine(TCM)is characterized by various active ingredients,relatively high safety,and lower treatment costs,which possess unique advantages in clinical applications.It has been widely used in the treatment of various diseases.Taking the regulation of ferroptosis by traditional Chinese medicine as the entry point may be a new direction for the future prevention and treatment of various diseases.In this review,we discussed the mechanism of iron lipid metabolic disorders based on ferroptosis and the research progress of traditional Chinese medicine intervention to provide reference and treatment strategies for the prevention and treatment of related diseases.

Objective:To investigate the correlation between hearing loss and microvascular complications in diabetes.Methods:This cross-sectional study conducted the data from 572 patients with diabetes hospitalized in the Endocrinology Department of the General Hospital of Southern Theater Command from September 2022 to July 2023. All participants underwent electrical audiometry and acoustic immittance in the ENY department. Based on the audiometric results, participants were categorized into normal hearing group and hearing loss group. Additionally, 572 non-diabetic patients from the outpatient department were enrolled as the non-diabetic group. The general information and laboratory results were collected and compared using t test, rank sum test or χ2 test. Binary logistic regression analysis was used to evaluate the association of diabetic hearing loss with diabetic kidney disease(DKD), diabetic retinopathy (DR), and diabetic peripheral neuropathy (DPN). Results:Among 572 patients with diabetes, 429 suffered from hearing loss and 143 were normal. χ2 test showed significant differences in combined DKD and DPN between two groups, but not in DR. Multivariate binary logistic regression analysis identified DKD and DPN as risk factors for hearing loss, but no correlation was found with DR. Conclusion:Diabetic patients with DKD or DPN should be monitored for potential hearing loss. Early screening and treatment are crucial to prevent severe hearing impairment.

ObjectiveTo explore the medication characteristics and clinical efficacy of the Tenghuang Jiangu tablets in the treatment of knee osteoarthritis （KOA） in the remission stage in the real world，providing references for rational clinical use of this prescription. MethodBased on the "registration system of KOA treated with Tenghuang Jiangu tablets"，2 439 KOA cases in the remission stage were analyzed by SPSS 25.0，IBM SPSS Modeler18.0，and Apriori algorithm. To be specific，the age，body mass index （BMI），and course of treatment were described in the form of x̄±s. The information on gender，K-L grade，daily dose，and frequency of drug use was described by frequency analysis. The number of cases，course of treatment，daily dose，and drug use frequency of the single-use group and the combined-use group were described by frequency analysis，and the combination of drugs was described by frequency analysis and Apriori algorithm. Mann-Whitney U test was employed to compare the scores of Visual Analogue Scale （VAS），Western Ontario and McMaster Universities Osteoarthritis Index （WOMAC），pain，stiffness，and joint function between the single-use group and the combined-use group. ResultThe results of clinical treatment showed that 2 439 patients with KOA in the remission stage were treated with Tenghuang Jiangu tablets，with 1 432 （58.71%） in the single-use group and 1 007 （41.29%） in the combined-use group. The average daily dose of Tenghuang Jiangu tablets was （3.90±1.44） g，and the majority of the patients were at grade Ⅱ （54.47%）. The daily average daily dose of Tenghuang Jiangu tablets in the single-use group was （3.64±1.35） g，which was lower than that in the combined-use group ［（4.26±1.48） g，P<0.05］. In the combined use，the top three western medicines were glucosamine （270 times，14.68%），sodium hyaluronate （126 times，6.85%），and imrecoxib （116 times，6.31%），and the top three Chinese medicines were Huoxuezhitong capsules/tablets/ointments （31 times，1.69%），Biqi capsules （25 times，1.36%），and Maizhiling （23 times，1.25%）. As for the overall clinical efficacy，the VAS score was （5.13±0.93） score before treatment and （2.22±1.18） score after treatment （P<0.05），with an overall average decrease of （2.91±1.14） score， and the average decrease in the single-use group was （2.76±1.43） score， which was lower than that in the combined-use group ［（3.12±1.36） score，（P<0.01）］. The WOMAC score was （31.05±11.84） score before treatment and （13.55±9.91） score after treatment （P<0.05）. The overall average decrease was （17.50±11.79） score， and the average decrease in the single-use group and combined-use group was （16.39±11.14） score and （19.08±12.50） score，respectively （P<0.01）. The patients with KOA>grade Ⅱ accounted for 91.34%（1 308/1 432） and 93.55%（942/1 007） in the single-use group and combined-use group，respectively （χ²=80.026，P<0.05）. A total of 43.37%（621/1 432） of the patients in the single-use group had other complications，lower than that in the combined-use group ［54.92%（553/1 432），（χ²=20.087，P<0.01）］. ConclusionMore than half of the patients with KOA in the remission stage are treated with Tenghuang Jiangu tablets alone，and the combination therapy is mainly applied in patients with severe conditions or other complications. In relieving knee joint pain and improving joint stiffness and joint function，both the Tenghuang Jiangu tablets alone and the combination therapy are effective.

ObjectiveTo investigate the clinical efficacy of Tenghuang Jiangu tablets （THJGT） combined with oral non-steroidal anti-inflammatory drugs （NSAIDs） in the treatment of osteoarthritis of the knee and its applicable stage based on real-world data， and provide a basis for the rational clinical use of THJGT. MethodA total of 218 cases treated with THJGT combined with oral NSAIDs included in the "THJGT for knee osteoarthritis case registry" from September 2019 to January 2021 were selected as the observation group， and 126 cases treated with oral NSAIDs alone as the control group （CG）. The data of gender， age， body mass index， Kellgren-Lawrence grading scale （K-L scale） score， visual analogue score （VAS score）， Western Ontario and McMaster Universities Osteoarthritis Index （WOMAC） score， swelling grade， joint fear of cold score， back pain and weakness score， and occurrence of adverse events/reactions of the patients in both groups were used for the evaluation of efficacy with full analysis set. The propensity score matching method was used to exclude the influence of confounding factors between groups， and the sub-data sets were established， with which the repeated measures analysis of variance （ANOVA） was carried out to evaluate the efficacy. Visit points were at registration， 4 weeks and 8 weeks after registration. The data were statistically analyzed in Excel 2019 and SPSS 23.0. ResultThe proportion of females in the observation group was 66.06% （144/218）， which was higher than that （58.73%， 74/126） in the control group （χ²=1.846）. The average age in the observation group was （61.12±7.01） years， which was higher than that ［（59.38±5.99） years］ in the control group （W=19 918.50， P<0.05）. The remission rate in the observation group was 98.17% （214/218）. In the observation group， the proportions of the patients at K-L grades Ⅱ and Ⅲ were 64.22% （144/218） and 25.23% （55/218）， respectively. The effect analysis of the whole data set for enrollment and treatment for 8 weeks showed that the VAS score of the experimental group decreased by （3.27±1.24） points on average， which was better than that of the control group [（2.75±1.20）， W=34 179.00， P<0.05]. The average WOMAC score decreased （23.43±11.46） points， which was better than that of the control group [（16.71±8.86）， W=32 387.00， P<0.05]. The average swelling grade decreased （0.63±0.64）， which was better than the control group [（0.33±0.59）， W=33 847.50， P<0.05]. The average score of joint chills decreased （1.90±1.84）， points， which was better than that of control group [（1.40±1.28）， W=35 165.00， P<0.05]. The average lumbar acid fatigue score decreased by （2.02±1.64） points, which was better than that of the control group [（1.10±1.28）， W=32 986.50， P<0.05]. Efficacy analysis of subdata sets for enrollment， 4 weeks of medication and 8 weeks of medication showed that VAS scores of both groups showed a downward trend after treatment， and the improvement of experimental group was more significant than that of control group at 4 weeks， with statistical significance （P<0.05）. After treatment， the total WOMAC score of both groups showed a downward trend， and the improvement of experimental groups was more significant at 4 weeks and 8 weeks （P<0.05）. After treatment， swelling， cold fear grade and lumbar acid fatigue score of both groups showed a decreasing trend,， and the improvement of experimental group was more significant at 8 weeks （P<0.05）. The therapeutic effect analysis of patients in the attack stage and remission stage of the experimental group showed that the total WOMAC score of the two groups showed a downward trend after treatment， and the trend was basically the same， and there was no statistical difference between the two groups at enrollment， 4 weeks after treatment， and 8 weeks after treatment （t=1.675， t=2.068， t=2.364）. The total WOMAC score of the patients in remission stage in the experimental group with K-L grading between grade 0 and grade Ⅲ had statistical significance at 4 weeks after treatment compared with the time of entry （P<0.05， P<0.01）. Group of adverse event rate was 4.13% （9/218）， lower than the control group 10.32% （13/126） （χ²= 5.109， P<0.05）. ConclusionThe population receiving THJGT combined with oral NSAIDs is mostly female， old， in remission， and with K-L grades Ⅱ and Ⅲ. THJGT can enhance the anti-inflammatory and analgesic effects of oral NSAIDs and keep the drug effect in improving joint function and alleviating fear of cold， swelling， and back pain and weakness. The drug combination can be applied to patients in both attack and remission， and the clinical application should take patient's disease stage and degree of osteoarthritis into account. Furthermore， the combination has the potential to reduce the incidence of adverse events caused by NSAIDs.

Objective:To analyze the safety and efficacy of left atrial appendage closure(LAAC)with Watchman in patients ≥85 years with atrial fibrillation(AF).Methods:515 elderly patients with atrial fibrillation, including 73 patients aged 85 years or older(85~91), who had undergone Watchman LAAC at Zhoupu Hospital affiliated to Shanghai Health Medical College from August 2016 to December 2020, were retrospectively analyzed.Of those ≥85 years, 44(60.3%)with transesophageal echocardiography records were assigned to the elderly group.Fifty-three patients aged 60 to 65 were selected as the control group.Differences in baseline data, intraoperative conditions, antithrombotic treatment plans and 1-year follow-up prognosis were compared between the two groups.Results:Compared with the control group, there was no difference in AF types, history of ischemic stroke/transient ischaemic attack(all P>0.05), but there were higher incidences of coronary heart disease and renal insufficiency, more severe heart failure, higher CHA 2DS 2-VASC(6.0±1.5 vs.3.6±1.5), HAS-BLED(3.2±1.2 vs.2.3±1.3)scores( t values were 7.682 and 3.871, respectively, P<0.05), and a lower one-stop surgery rate(6 cases or 13.6% vs. 27 cases or 50.9%, χ2=10.517, P<0.05)in the advanced age group.There was no difference in the diameter of the Watchman device, rate of device replacement, compression percentage and residual flow between the two groups during the perioperative period.The incidences of device-related thrombosis were 4.5%(2/44)and 3.8%(2/53)for the advanced age group and the control group, respectively, but the difference was not statistically significant( P>0.05). During the 12-month follow-up, there were no cases of ischemic stroke or intracerebral hemorrhage.Three died of heart failure and 1 died of cancer. Conclusions:LAAC with Watchman is safe and effective for patients over 85 years with AF, but the decision on the procedure should be based on careful assessment of patients' cardiac and renal function and general health.
