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.

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.

Multiple myeloma (MM) is the second most common hematologic malignancy. In recent years, the advent of a new generation of drugs including proteasome inhibitors and immunomodulatory drugs has significantly improved the prognosis of MM patients, extending the median survival to 3-6 years. Meanwhile, chimeric antigen receptor T-cell (CAR-T) immunotherapy has made great progress in treating relapsed/refractory MM, but the high relapse rate and short remission duration are still challenges for CAR-T therapy. Therefore, it is imperative to explore factors affecting the efficacy and safety of CAR-T therapy and optimize the treatment strategies. This article reviews the recent advances in CAR-T therapy for MM reported at the 65th American Society of Hematology (ASH) Annual Meeting in 2023.

Purpose To evaluate the differential diagnostic value of conventional ultrasound in the ureteral polyps and ureteral carcinoma via continuous observation.Materials and Methods The conventional ultrasound of patients with ureteral polyps and ureteral carcinoma treated in Shaanxi Provincial People's Hospital were retrospectively analyzed from June 2015 to June 2022.According to the pathological results,all participants were divided into the ureteral polyp group(98 cases)and the ureteral carcinoma group(151 cases).All clinical and ultrasound data were recorded,and the differences of echo,blood flow and peristalsis were compared between the two groups.Results There were significant differences in ureteral peristalsis,color Doppler flow distribution,periureteral tissue thickening,increased echo,and hydronephrosis(χ2=197.50,138.89,26.97,36.13,all P<0.05)between the two groups.Low echo was predominant in both groups[67(68.37)vs.114(75.50)],with no significant difference(χ2=1.52,P>0.05).In the ureteral polyp group,67 cases were found in the upper ureter,89 cases were observed continuously with common peristalsis,and 73 cases with color blood flow were mostly central blood flow,while in the ureteral cancer group,85 cases were found in the middle and lower ureter,148 cases showed almost no peristalsis,and 122 cases with color blood flow were mostly peripheral blood flow.Conclusion There are some differences in clinical features such as the location as well as whether hydronephrosis between ureteral polyps and carcinoma.Peristalsis can provide the differential diagnosis for ureteral polyps and ureteral carcinoma via continuous observation.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

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.
