Objective To analyze trend changes of disease burden of hypertensive nephropathy (HTN) between 2012 and 2023 in Chongqing, and to provide the suggestion for HTN prevention and treatment. Methods Death cases of HTN from Chongqing death registration data between 2012 and 2023 were analyzed to calculate indicators such as mortality, age standardization mortality rate (ASMR), rate of years of life lost (YLL) and Average years of life lost. The mortality of HTN between male and female, urban and rural were compared by Chi-square test. The trend change was explained by average annual percent of change (AAPC). Results The mortality and standardized mortality of HTN in Chongqing decreased from 5.44/100 000 and 3.13/100 000 in 2012 to 2.76/100 000 and 1.07/100,000 in 2023 respectively. The average annual percent change (AAPC) was -5.41% and -8.35% respectively, and the differences in the change trends were statistically significant (P<0.01). The mortality and standardized mortality of HTN in males and females decreased with AAPC of 5.50%, 8.07%, 5.27% and 8.69% respectively, and the differences in the change trends were all statistically significant (all P< 0.05). From 2012 to 2014, 2019 and 2021, the mortality rate of HTN in rural areas was higher than that in urban areas (all P < 0.05). The mortality and standardized mortality of HTN in rural areas decreased with AAPC of 6.58% and 9.46% respectively, and the differences in the change trends were all statistically significant (all P<0.05). The rate of YLL and standardized YLL of HTN in Chongqing decreased from 96.02/100 000 and 60.42/100 000 in 2012 to 44.98/100 000 and 21.49/100 000 in 2023 respectively. The AAPC was -5.83% and -7.80% respectively, and the differences in the change trends were statistically significant (both P < 0.05). AYLL of HTN were 17.88 years in 2012, and it was 17.08 years in 2023. There were no statistically significant differences in the changes (both P > 0.05). The standardized AYLL of HTN in rural areas increased at an average annual rate of 1.14%, and the difference was statistically significant (P < 0.05). Conclusion The mortality and YLL rate of HNT in Chongqing was lower than it in China. Moreover, its trend was decreased. It should be strengthened early screening and healthy management of HNT.

OBJECTIVE:
Left ventricular remodeling induced by myocardial ischemia/reperfusion injury (MI/RI) is a common cardiac dysfunction. Accumulating evidence has demonstrated that autophagy plays a vital role in protecting against ventricular remodeling. This study aims to investigate the performance of Compound Danshen Tablets (CDT) in rescuing ventricular remodeling and whether autophagy as the potential mechanism.
METHODS:
The left anterior descending arteries of rats were temporarily ligated for 30 min to construct the MI/RI model. Ventricular remodeling was induced by reperfusion for 28 d, during which the MI/RI rats were administered CDT (300 mg/kg and 600 mg/kg), atorvastatin (2 mg/kg), and diltiazem (16 mg/kg). Cardiac function and structure were examined by echocardiography. Immunohistochemistry, Masson's trichrome staining, and hematoxylin-eosin (HE) staining were utilized to assess the fibrosis and histological alterations in the heart tissue. The expression of autophagy-related proteins was detected using Western blotting.
RESULTS:
CDT attenuated the cardiac dysfunction, structural changes, histopathological changes and fibrosis induced by MI/RI. CDT significantly enhanced the level of Beclin1 and microtubule-associated protein 1 light chain 3 beta (LC3β), and reduced p62 levels in MI/RI rats. Moreover, CDT significantly increased the phosphorylation of adenosine monophosphate-activated protein kinase (AMPK) and inhibited mammalian target of rapamycin (mTOR) phosphorylation.
CONCLUSION
CDT ameliorated MI/RI-induced ventricular remodeling by activating autophagy and improving autophagic flux via the AMPK/mTOR signaling pathway.

With the rising prevalence of chronic diseases and an aging population,China's traditional segmented health-care delivery model is increasingly inadequate for meeting the growing demand for long-term,systematic health management.In response,the"Physician-Pharmacist Co-management"model has emerged,aiming to enhance the quality and continuity of care through close collaboration between physicians and pharmacists.This paper starts from the concept and origin of"Physician-Phar-macist Co-management"model,focusing on its China-specific advantages shaped by national healthcare policies and clinical real-ities.Unlike the internationally recognized Collaborative Drug Therapy Management(CDTM)model,the Chinese approach re-flects local healthcare structures and needs.Using obstructive pulmonary disease(COPD)as a case study,we examine the mod-el's application and value in managing chronic respiratory diseases.Data indicate that,after the implementation of"physician-pharmacist co-management"model in COPD patients,the CAT score decreased by approximately 24%,the annual rate of acute exacerbation-related hospitalizations declined by about 72%,and the proportion of patients with regular pulmonary rehabilitation exercise habits increased by roughly 3.3-fold.Additionally,the percentage of patients without adverse reactions rose from 47.37%to 64.41%,and the vaccination rate increased by about 2.7-fold.These findings demonstrate the model's significant advantages in improving clinical outcomes,enhancing patient adherence,and reducing healthcare costs.Despite benefits,howev-er,the"Physician-Pharmacist Co-management"model in China faces several challenges,including limited public awareness,gaps in pharmacist training,and insufficient policy support.To address these challenges,this study recommends strengthening public education,establishing comprehensive evaluation systems for pharmaceutical professionals,and improving incentive mech-anisms.Overall,the findings suggest that the"Physician-Pharmacist Co-management"model holds considerable promise for im-proving the quality of chronic disease management,enhancing patient adherence,and optimizing healthcare resource utilization in China.

ObjectiveTo investigate the ameliorative effect and mechanism of total saponins of Codonopsis Radix (TSC) on learning and memory impairment induced by D-galactose in aging mice. MethodTwenty-four male C57BL/6J mice were randomly assigned into four groups (n=6): normal group, model group (200 mg·kg-1 D-galactose), TSC group (200 mg·kg-1), and donepezil group (3 mg·kg-1). After one week of pre-treatment, the mice in the model, TSC, and donepezil groups were administrated with corresponding agents for 8 weeks. In the ninth week, the Morris water maze test was performed to assess the learning and memory abilities. Histopathological changes in the brain were evaluated by hematoxylin-eosin (HE) and Nissl staining. Immunohistochemistry was used to detect the expression of nuclear factor kappa-B (NF-κB), tumor necrosis factor-α (TNF-α), and brain-derived neurotrophic factor (BDNF) in the brain tissue. The serum levels of glutathione peroxidase (GSH-Px), catalase (CAT), superoxide dismutase (SOD), malondialdehyde (MDA), TNF-α, interleukin-1β (IL-1β), and interleukin-18 (IL-18) were measured by enzyme-linked immunosorbent assay, on the basis of which the effects of TSC on neuroinflammation and memory impairment in D-galactose-induced aging mice were assessed. ResultCompared with the normal group, the model group exhibited decreased cognitive function, decreased activities of CAT, SOD, and GSH-Px in the serum (P<0.01), and upregulated levels of MDA, TNF-α, IL-1β, and IL-18 (P<0.01). In addition, partial neuronal damage and degeneration were observed in the hippocampus and cortex of the model group, accompanied by downregulated BDNF expression (P<0.05) and upregulated NF-κB and TNF-α expression (P<0.05). Compared with the model group, TSC alleviated D-galactose-induced cognitive dysfunction, enhanced the activities of CAT, SOD, and GSH-Px (P<0.01), lowered MDA, TNF-α, IL-1β, and IL-18 levels (P<0.01), and ameliorated the pathological changes in the hippocampus and cerebral cortex. Additionally, TSC upregulated BDNF expression (P<0.05, P<0.01) and downregulated NF-κB and TNF-α expression (P<0.05, P<0.01) in the hippocampus and cerebral cortex. ConclusionTSC exerts a protective effect on cognitive dysfunction induced by D-galactose in aging mice by inhibiting oxidative stress and inflammation.

Objective To evaluate the optimal traction amount for treating scoliosis using halo pelvic ring traction(HPRT)and provide theoretical references for clinical surgical assessment and rehabilitation.Methods A three-dimensional(3D)model of the thoracolumbar spine including the spinal cord was created and validated.Five traction amounts(10,15,20,25,30 mm)were applied to the model.The biomechanical responses of the spine under different traction conditions were simulated to determine the optimal amount of traction.Results As the traction increased,the Cobb angle decreased progressively.Significantly,in the range of 15-20 mm,the reduction in Cobb angle accounted for 50%-70.5%of the maximum reduction.The spinal stress at the main curvature represented 47.4%-67.5%of the maximum stress.Meanwhile,the stresses in the gray and white matter of the spinal cord were 70.3%-84.5%and 68.8%-83.9%of their respective maximum stresses.Conclusions The traction amounts between 15 mm and 20 mm are optimal for treating scoliosis.This range maximizes the Cobb angle correction while maintaining lower stress levels and thereby,reduces the risk of damage to the spine and spinal cord.
