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.

Basket trial, as an innovative clinical trial design concept, marks the transformation of medical research from the traditional large-scale and single-disease treatment to the precise and individualized treatment. By gradually incorporating the Bayesian method during development, the trial design becomes more scientific and reasonable and increases its efficiency. The fundamental principle of the Bayesian method is the utilization of prior knowledge in conjunction with new observational data to dynamically update the posterior probability. This flexibility enhances the basket trial's capacity to effectively adapt to variations during the research process. Consequently, it enables researchers to dynamically adjust research strategies based on accumulated data and improve the predictive accuracy regarding treatment responses. In addition, the design concept of the basket trial aligns with the traditional Chinese medicine(TCM) principle of "homotherapy for heteropathy". The principle of "homotherapy for heteropathy" emphasizes that under certain conditions, different diseases may have the same treatment. Similarly, basket trials allow using a uniform trial design across multiple diseases, offering enhanced operational and significant practical value in the realm of TCM, particularly within the context of syndrome-based disease research. By introducing basket trials, the design of TCM clinical studies will be more scientific and yield higher-quality evidence. This study systematically categorized various Bayesian methods and models utilized in basket trials, evaluated their strengths and weaknesses, and identified their appropriate application contexts, so as to offer a practical guide for designing basket trials in the realm of TCM.

BACKGROUND: Based on the China-VHD database, this study sought to develop and validate a Valvular Heart Disease- specific Age-adjusted Comorbidity Index (VHD-ACI) for predicting mortality risk in patients with VHD. METHODS & RESULTS: The China-VHD study was a nationwide, multi-centre multi-centre cohort study enrolling 13,917 patients with moderate or severe VHD across 46 medical centres in China between April-June 2018. After excluding cases with missing key variables, 11,459 patients were retained for final analysis. The primary endpoint was 2-year all-cause mortality, with 941 deaths (10.0%) observed during follow-up. The VHD-ACI was derived after identifying 13 independent mortality predictors: cardiomyopathy, myocardial infarction, chronic obstructive pulmonary disease, pulmonary artery hypertension, low body weight, anaemia, hypoalbuminaemia, renal insufficiency, moderate/severe hepatic dysfunction, heart failure, cancer, NYHA functional class and age. The index exhibited good discrimination (AUC, 0.79) and calibration (Brier score, 0.062) in the total cohort, outperforming both EuroSCORE II and ACCI (P < 0.001 for comparison). Internal validation through 100 bootstrap iterations yielded a C statistic of 0.694 (95% CI: 0.665-0.723) for 2-year mortality prediction. VHD-ACI scores, as a continuous variable (VHD-ACI score: adjusted HR (95% CI): 1.263 (1.245-1.282), P < 0.001) or categorized using thresholds determined by the Yoden index (VHD-ACI ≥ 9 vs. < 9, adjusted HR (95% CI): 6.216 (5.378-7.184), P < 0.001), were independently associated with mortality. The prognostic performance remained consistent across all VHD subtypes (aortic stenosis, aortic regurgitation, mitral stenosis, mitral regurgitation, tricuspid valve disease, mixed aortic/mitral valve disease and multiple VHD), and clinical subgroups stratified by therapeutic strategy, LVEF status (preserved vs. reduced), disease severity and etiology. CONCLUSION The VHD-ACI is a simple 13-comorbidity algorithm for the prediction of mortality in VHD patients and providing a simple and rapid tool for risk stratification.

BACKGROUND:Nowadays,there are increasing reports on the digitization and visualization system of acupuncture points for adults in traditional Chinese medicine,and the digitization and visualization system of acupuncture points for children in traditional Chinese medicine and the simulation system of acupuncture manipulation for Mongolian medicine training have been reported.However,there are no reports on relevant systems for children in Mongolian medicine. OBJECTIVE:To develop a simulation system of acupuncture points for children in Mongolian medicine,in the hope that it can be used for clinical teaching,manipulation practice and research on acupuncture safety. METHODS:Based on the tomographic anatomical dataset of preschool boys,a three-dimensional(3D)digital virtual anatomical model of children with multiple internal organs and tissues was constructed by using PhotoShop.2021 and Digihuman Reconstruction System software.The relevant annotation information database of 27 acupoints such as Dinghui acupoint of Mongolian medicine was compiled by the Unity database language.The Mongolian gold needle and silver needle were selected to record the acupuncture point teaching video on the 3D printed head and neck resin model of children.In Unity3D software,children's anatomical model,acupoint annotation information database and acupuncture operation video were integrated and coded,and a 3D digital children's Mongolian acupuncture acupoint visualization system integrating simulation acupuncture training,clinical teaching and acupuncture safety research was successfully created. RESULTS AND CONCLUSION:This study was based on real children's specimens.In order to reduce the error of two-dimensional segmentation,the manual layer-by-layer segmentation section image method was used to ensure the accuracy of the 3D model to the greatest extent.The Digihuman Reconstruction System was used to extract and save the individual segmentation data while maximizing the accuracy of the 3D model.PhotoShop.2021 software was used to complete the 3D reconstruction of the outer skin of the head and neck of children and the internal bony structure,cervical spinal cord,blood vessels and nerves,muscles and ligaments.After 3D reconstruction,the basic morphology of each independent structure and the integrity of the overall contour were verified in MeshLab software and the final fine adjustment and anatomical position confirmation were conducted using 3-matic research 13.0 software.The real anatomical morphology of the head and neck of preschool children was successfully simulated and restored.Unity3D software was used to integrate the 3D model of children,acupuncture operation video and acupoint annotation database,and the 3D digital Mongolian acupuncture acupoint visualization system for children was successfully constructed.Based on the real continuous fault ultra-thin dataset of preschool boys in China,China's first 3D digitization and visualization system of acupuncture points in the head and neck of children in Mongolian medicine was developed.Compared with the previous acupuncture soft works,this system is more suitable for the anatomical morphological development characteristics of Asian children,and has a high value of application in the fields of research on the safety of acupuncture in Mongolian medicine,clinical teaching and acupuncture simulation training.

Studies have suggested that the nucleus accumbens (NAc) is implicated in the pathophysiology of major depression; however, the regulatory strategy that targets the NAc to achieve an exclusive and outstanding anti-depression benefit has not been elucidated. Here, we identified a specific reduction of cyclic adenosine monophosphate (cAMP) in the subset of dopamine D1 receptor medium spiny neurons (D1-MSNs) in the NAc that promoted stress susceptibility, while the stimulation of cAMP production in NAc D1-MSNs efficiently rescued depression-like behaviors. Ketamine treatment enhanced cAMP both in D1-MSNs and dopamine D2 receptor medium spiny neurons (D2-MSNs) of depressed mice, however, the rapid antidepressant effect of ketamine solely depended on elevating cAMP in NAc D1-MSNs. We discovered that a higher dose of crocin markedly increased cAMP in the NAc and consistently relieved depression 24 h after oral administration, but not a lower dose. The fast onset property of crocin was verified through multicenter studies. Moreover, crocin specifically targeted at D1-MSN cAMP signaling in the NAc to relieve depression and had no effect on D2-MSN. These findings characterize a new strategy to achieve an exclusive and outstanding anti-depression benefit by elevating cAMP in D1-MSNs in the NAc, and provide a potential rapid antidepressant drug candidate, crocin.

【Objective】 To investigate the association between genetic variations in the glucagon-like peptide-1 receptor (GLP-1R) gene and BP responses to sodium and potassium intake. 【Methods】 A total of 514 subjects from 124 families were recruited in Meixian County, Shaanxi Province, in 2004, resulting in the establishment of a "salt-sensitive hypertension study cohort" . The subjects followed a dietary regimen which involved a normal diet for 3 days, a low-salt diet for 7 days, a high-salt diet for 7 days, and a high-salt potassium-supplemented diet for 7 days. BP measurement was conducted at different intervention periods, and peripheral blood samples were collected. Additionally, eight single nucleotide polymorphisms (SNPs) of the GLP-1R gene were genotyped using the MassARRAY detection platform. 【Results】 The GLP-1R gene SNP rs9462472 exhibited a significant association with systolic BP, diastolic BP, and mean arterial pressure response to high-salt intervention. Similarly, SNP rs2268637 showed a significant association with systolic BP response to high-salt intervention. Furthermore, SNP rs2268637 was significantly associated with systolic BP and mean arterial pressure responses to high-salt plus potassium supplementation intervention. 【Conclusion】 Our findings indicate a significant association of genetic variations in the GLP-1R gene with BP responses to sodium and potassium intake. This suggests that the GLP-1R gene plays a role in the regulation of BP salt sensitivity and potassium sensitivity.

Objective To investigate the relationship of miRNA gene polymorphisms with blood pressure(BP)responses to the sodium and potassium diet intervention.Methods In 2004,we recruited 514 participants from 124 families in seven villages of Baoji,Shaanxi Province,China.All subjects were given a three-day normal diet,followed by a seven-day low-salt diet,a seven-day high-salt diet,and finally a seven-day high-salt and potassium supplementation.A total of 19 miRNA single nucleotide polymorphisms(SNPs)were selected for analysis.Results Throughout the sodium-potassium dietary intervention,the BP of the subjects fluctuated across all phases,showing a decrease during the low-salt period and an increase during the high-salt period,followed by a reduction in BP subsequent to potassium supplementation during the high-salt diet.MiR-210-3p SNP rs 12364149 was significantly associated with systolic BP(SBP),diastolic BP(DBP)and mean arterial pressure(MAP)responses to low-salt diet.MiR-4638-3p SNP rs6601178 was significantly associated with SBP while miR-26b-3p SNP rs115254818 was significantly associated with MAP responses to low-salt intervention.In addition,miR-26b-3p SNP rs115254818 was significantly correlated with SBP,DBP and MAP responses to high-salt intervention.MiR-1307-5p SNPs rs1 1191676 and rs2292807 were associated with SBP and MAP responses to high-salt diet.MiR-4638-3p SNP rs6601178,miR-210-3p SNP rs12364149,miR-382-5p SNP rs4906032 and rs4143957 were significantly associated with SBP response to high-salt diet.In addition,miR-26b-3p SNP rs115254818 was significantly associated with SBP,DBP and MAP responses to potassium supplementation.MiR-1307-5p SNPs rs11191676,rs2292807,and miR-19a-3p SNP rs4284505 were significantly associated with SBP responses to high-salt and potassium supplementation.Conclusion miRNA gene polymorphisms are associated with BP response to sodium and potassium,suggesting that miRNA genes may be involved in the pathophysiological process of salt sensitivity and potassium sensitivity.

Botulinum toxin(BoNT)is currently the first-line method for treating focal dystonia,which causes muscle paralysis by chemical denervation.Recent neuroimaging studies have found that BoNT treatment could alter neuroplasticity in the brain of patients with focal dystonia.However,the specific central nervous system mechanisms have not been fully elucidated.To this end,here we review the neuroimaging studies on BoNT treatment for dystonia from three aspects:functional magnetic resonance imaging,structural magnetic resonance imaging,and positron emission tomography imaging.It suggests that BoNT may improve the symptoms of dystonia patients by affecting functional connectivity,microstructure,and metabolic levels of the cortex,basal ganglia,thalamus,and cerebellum,etc.Therefore,this review will provide a theoretical reference for further exploring the mechanism and developing potential therapeutic targets of dystonia.

Neuregulin 4 (NRG4) is a newly discovered adipokine,which plays crucial roles in many physiological processes such as energy balance,and glucose and lipid metabolism.The transcriptional regulation of NRG4 gene remains largely unknown.Our previous 5'RACE analysis showed that the tran-scription start sites (TSS) of chicken NRG4 gene were dispersed over a region of 200 bp,suggesting that chicken NRG4 gene possesses a dispersed promoter.In the present study,the promoter activity of the proximal exon and intron of chicken NRG4 gene was analyzed.Dual-luciferase reporter assay demonstra-ted that the genomic fragment (-122/+452) containing exon 1,intron 1,and exon 2 of chicken NRG4 gene had strong bidirectional promoter activity.Bioinformatics analysis showed that there was a putative binding site of the transcription factor CCAAT enhancer-binding proteinα(C/EBPα) in exon 2 of chick-en NRG4 gene.Reporter gene assay showed that both deletion and site-directed mutagenesis of the C/EBPα binding site abrogated the regulatory effect of C/EBPα on the promoter activity of the-122/+452 fragment of chicken NRG4 gene.Gene expression correlation analysis showed that C/EBPα and NRG4 gene expression were positively correlated in chicken adipose tissues.ChIP-PCR revealed that C/EBPα directly binds to the exon 2 of NRG4 gene in chicken adipose.In conclusion,the proximal exon and intron of chicken NRG4 gene has bidirectional promoter activity,and C/EBPα directly regulates NRG4 gene expression in chicken adipose via binding to its exon 2.

Depression is a common mental illness in adolescents, and some patients do not respond well after medication, which may be partly related to vitamin D deficiency and insufficient calcium intake. This paper reports a 15-year-old patient with depression, whose condition was still unstable and the effect was not good despite routine use of antidepressant drugs and psychological intervention. After adequate supplementation of vitamin D and calcium, the patient's depression improved significantly, and the follow-up for 4 months, the condition was stable and did not recur.
