Objective To systematically analyze the characteristics of the disease burden of hypertensive heart disease (HHD) in the elderly (≥60 years) globally and in China from 1990 to 2021, and to predict its future trends from 2022 to 2040, with the aim of providing data support for optimizing comprehensive prevention and control strategies for HHD. Methods Based on the Global Burden of Disease (GBD) 2021 database, the number of prevalent cases and disability-adjusted life years (DALYs) of HHD in the elderly were extracted for the world, China, and five regions categorized by sociodemographic index (SDI). Joinpoint regression was used to analyze the temporal trends of age-standardized prevalence rate and age-standardized DALYs rate of HHD in the elderly. A three-factor decomposition method was applied to evaluate the relative contributions of aging, population growth, and epidemiological changes to the variations in the elderly HHD burden. Additionally, a Bayesian age-period-cohort model was used to predict the elderly HHD burden from 2022 to 2040. Results In 2021, the number of prevalent elderly HHD cases reached 10 283 000 globally and 3 412 400 in China, representing increases of 179.20% and 159.20% respectively, compared with 1990. The DALYs of elderly HHD were 18 812 700 person-years globally and 4 731 400 person-years in China, rising by 76.08% and 29.45% respectively from 1990. Meanwhile, the growth rates of the number of prevalent cases and DALYs of elderly HHD varied across different SDI regions. From 1990 to 2021, the age-standardized prevalence rate of elderly HHD in China, as well as the age-standardized DALYs rate of elderly HHD both globally and in China, showed significant downward trends (all average annual percentage changes<0, all P<0.001). In 2021, the 70-74 years age group accounted for the highest proportion of prevalent cases and DALYs of elderly HHD, both globally and in China. Decomposition analysis revealed that population growth was the dominant factor driving the increase in the elderly HHD burden across all regions. The prediction model results indicated that the number of prevalent cases and DALYs of elderly HHD would continue to rise globally and in China from 2022 to 2040, with the growth rate of the elderly HHD burden in China between 2021 and 2040 expected to exceed the global average. Conclusion Over the past 32 years, although the age-standardized disease rates of elderly HHD have mainly shown a downward trend globally and in China, the absolute number of the disease burden has increased substantially. The projection model indicates a continued upward trajectory, with the growth rate in China higher than the global average. Therefore, there is an urgent need to implement precise prevention and control strategies to effectively mitigate the disease burden of elderly HHD.

Allergic rhinitis (AR) is one of the most common chronic non-infectious inflammatory diseases in children. Traditional Chinese medicine (TCM) employs a comprehensive therapeutic system integrating treatment by stages and syndrome differentiation and treatment, demonstrating significant advantages in the management of pediatric AR. This article systematically reviews the clinical treatment methods and underlying mechanisms of TCM for pediatric AR in recent years. It is found that internal therapies (such as herbal formulas or Chinese patent medicines like Xiaoqinglong decoction, Yiqi tuomin decoction), external therapies (including intradermal needles, acupoint application, tuina, and herbal nasal therapy), as well as combined internal and external approaches (oral herbs combined with acupoint application), have demonstrated significant effects in alleviating clinical symptoms, improving immune indicators, and reducing recurrence rates in children with AR. The underlying mechanisms are primarily associated with the regulation of signaling pathways such as Toll-like receptor/nuclear factor-kappa B and mitogen-activated protein kinase, thereby modulating immune balance, suppressing inflammatory responses, inhibiting pyroptosis, reducing mucus secretion, and promoting nasal mucosal repair.

This study investigates the molecular complexities of non-alcoholic fatty liver disease (NAFLD)-induced brain dysfunction, with a focus on the liver-intestine-brain axis and potential therapeutic interventions. The main objectives include understanding critical microbiota shifts in NAFLD, exploring altered metabolites, and identifying key regulatory molecules influencing brain function. The methods employed encompassed 16S ribosomal RNA (rRNA) sequencing to scrutinize stool microbiota in NAFLD patients and healthy individuals, non-targeted metabolomics using LC-MS to uncover elevated levels of deoxycholic acid (DCA) in NAFLD mice, and single-cell RNA sequencing (scRNA-seq) to pinpoint the pivotal gene Hpgd in microglial cells and its downstream Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signaling pathway. Behavioral changes and brain function were assessed in NAFLD mice with and without Fecal microbiota transplantation (FMT) treatment, utilizing various assays and analyses. The results revealed significant differences in microbiota composition, with increased levels of Bacteroides in NAFLD patients. Additionally, elevated DCA levels were observed in NAFLD mice, and FMT treatment demonstrated efficacy in ameliorating liver function and brain dysfunction. Hpgd inhibition by DCA activated the JAK2/STAT3 pathway in microglial cells, leading to inflammatory activation, inhibition of mitochondrial autophagy, induction of neuronal apoptosis, and reduction in neuronal action potentials. This study elucidates the intricate molecular mechanisms underlying the liver-gut-brain axis in NAFLD, and the identification of increased DCA and the impact of JAK2/STAT3 signaling on microglial cells highlight potential therapeutic targets for addressing NAFLD-induced brain dysfunction.

Objective To investigate the incidence of central obesity and characteristics and changing trend of macronutrient energy supply in adult residents of Chongqing, and to analyze the relationship between carbohydrate energy supply and central obesity. Methods Using the longitudinal tracking data of China Health and Nutrition Survey project, combined with China food composition table , the energy and nutrient intake and macronutrient energy supply ratio were calculated. The association between carbohydrate energy supply and central obesity was analyzed by multi-level statistical model. Results In 2011, 2015 and 2018, the carbohydrate supply ratio of adult residents in Chongqing was 43.02%, 46.52%, and 46.07%, respectively, and the difference was statistically significant (F=18.699, P<0.001). The overweight rates in 2011, 2015, and 2018 were 29.2%, 36.7%, and 37.8%, while the obesity rates were 12.2%, 13.5%, and 19.5%, respectively, with statistically significant differences (χ2=41.416, P<0.001). The central obesity rates were 51.5%, 57.2%, and 62.8%, respectively (χ2=21.008, P<0.001). The carbohydrate supply ratio was positively correlated with waist circumference. Compared to the population with a carbohydrate to energy ratio of <55%, the risk of central obesity in the population with a carbohydrate to energy ratio of ≥ 65% was 1.63 times higher. Conclusion The ratio of carbohydrate to energy supply of adult residents in Chongqing has slightly increased. Rates of overweight, obesity and central obesity are on the rise. A high carbohydrate to energy supply ratio may be a risk factor for central obesity.

Objective:To investigate the correlation between cardiac polyps and gastroesophageal flap valve (GEFV).Methods:The clinical, endoscopic and pathological data of 349 patients with cardiac polyps (the cardiac polyp group) visiting Affiliated Hospital of Yangzhou University from January 1, 2016 to December 31, 2021 were retrospectively collected, and the same number of non-cardiac polyp patients (the non-cardiac polyp group) were matched in the same period as control according to the propensity score. The clinical, endoscopic and pathological data of the two groups were compared.Results:After matching with propensity score, there were 296 patients in each group, with no significant differences in smoking, acid reflux, heartburn, Helicobacter pylori infection, bile reflux, reflux esophagitis or pancreatitis between the two groups ( P>0.05). Compared with the non-cardiac polyp group, the risk of cardiac polyps increased in GEFV Ⅱ patients ( OR=3.046, 95%CI: 2.100-4.419, P<0.001) and GEFV Ⅲ patients ( OR=4.202, 95%CI: 2.299-7.681, P<0.001). Compared with the non-cardiac polyp group, the risk of cardiac polyps increased in patients with GEFV abnormalities ( OR=2.822, 95%CI: 1.615-4.931, P<0.001). GEFV abnormalities was associated with the cardiac polyp site ( χ2=22.169, P=0.003) and was not significantly associated with cardiac polyp size, number, morphology, intestinal metaplasia of the surrounding mucosa or intraepithelial neoplasia ( P>0.05). Conclusion:The occurrence of cardiac polyps is related to GEFV, and the patients with GEFV abnormalities are more likely to develop cardiac polyps.

Objective To investigate the mechanism of cartilage injury and inflammation in the WHBE rabbit KOA model and the effect of platelet-rich fibrin releasates(PRFr)treatment on the KOA process,we established a WHBE rabbit KOA model by excision of medial collateral and partial patellar ligaments and administered a PRFr solution.Methods Twenty-four WHBE rabbits were randomly divided into three groups:normal control(NC)group(n=6),model(KOA)group(n=12),and cure(PRFr)group(n=6).KOA and PRFr groups were injected with 0.5 mL saline and PRFr into both joint cavities on 7 and 14 postoperative days,respectively.At 4 and 8 weeks of modeling,the knee joint grade scoring,X-ray imaging,and gross scoring were performed.Serum levels of IL-1β,TNF-α,and MMP-13 were measured by ELISA.At 4 weeks,6 animals in the KOA group were euthanized,and at 8 weeks,the remaining animals in each group were euthanized.Pathological sections were prepared after decalcification,and then HE,toluidine blue,and safranin O-fast green staining and immunohistochemical analysis of TGF-β,BMP3,and NF-κB were conducted.Results The Lequesne MG behavioral score,Mankin's score,and Pelletier score of WHBE rabbits after the operation were significantly increased compared with the NC group(P<0.01).Pathological observations revealed surface defects of the cartilage and partial loss of chondrocytes.These result indicated that the KOA model was established successfully.In KOA rabbits,knee joint swelling,joint pain stimulation,and movement limitation were obvious.X-rays showed a high-density soft tissue shadow,indicating more joint effusion and a rough articular surface in general.After PRFr treatment,the serum levels of proinflammatory factors IL-1β,TNF-α,and MMP-13 in KOA model rabbits were significantly reversed(P<0.05,P<0.01).Additionally,the cartilage surface became smooth,and most chondrocytes were neatly distributed.Expression levels of TGF-β,BMP3,and NF-κB induced by KOA were also significantly decreased(P<0.01).Conclusions We successfully established a KOA model in WHBE rabbits,and PRFr improved the cartilage injury and inflammation of the WHBE rabbit KOA model through TGF-β/BMP and NF-κB pathways.

Objective To establish a rat model of hyperuricemic nephropathy(HN)using a multifactorial induction method of potassium oxazinate combined with adenine and yeast feed to observe the intervention effect of Qiling granules(QLG).Methods Fifty-eight SPF-grade male SD rats were selected,and 10 rats were randomly allocated to the normal control(NC)group.The remaining rats were induced by multiple factors to establish HN rat models.After 2 weeks of modeling,submandibular blood samples were taken to detect serum UA,CREA,BUN,TG,and TC.Forty HN rats with bleeding clearance UA and body weight close to the mean were selected.They were randomly divided into a model(M)group,QLG low dose(QLG-L)groups,QLG high dose(QLG-H)group,and a positive control(PC)group,with 10 rats in each group,using a stratified randomization method.Each group was given corresponding drugs by gavage daily,and after continuous administration for 4 weeks,submandibular blood samples were taken to detect serum UA,CREA,BUN,TG,and TC.After euthanasia of the rats,liver tissue was taken to detect XOD and ADA activity.Renal tissue was taken for HE and Gomori hexamine silver staining,and the protein expression of GLUT9,OAT1,VCAM-1,and TGF-β in the kidneys was observed using immunohistochemistry and Western blot method.Results Compared with the NC group,the M group's serum levels of UA,CREA,BUN,TC,and TG,as well as liver XOD and ADA activities,were significantly increased(P<0.01).The renal tissue of the model rats showed significant pathological changes.The area of renal tubules positive for urate and the expression of GLUT9,VCAM-1,and TGF-β proteins in the kidneys were significantly increased(P<0.01,P<0.05),while the expression of OAT1 was significantly reduced(P<0.01).Compared with the M group,each treatment group showed significantly reduced serum UA levels,liver XOD,ADA activity,and renal VCAM-1 protein expression(P<0.01,P<0.05).The serum CREA and BUN levels and renal TGF-β protein expression of rats in the QLG-L group were significantly reduced(P<0.05,P<0.01).The serum CREA and BUN levels and renal GLUT9 protein expression of rats in the QLG-H group were also significantly reduced(P<0.01,P<0.05).The urate deposition and renal injury caused by each treatment were reduced to varying degrees,but there were no significant differences among groups(P>0.05).Conclusions A stable HN rat model can be induced by gavage of potassium oxyzinate and adenine in combination with yeast feed.QLG can effectively treat HN by improving UA metabolic disorders,reducing the renal inflammation and urate deposition that cause renal damage in HN model rats.Its mechanism of action is related to a reduction in serum UA,CREA,BUN,and TG levels;liver XOD and ADA activities;and the expression of GLUT9,OAT1,VCAM-1,and TGF-β proteins in the kidneys.
