Objective To analyze the disease burden,changing trends,and differences of atrial fibrillation(AF)/atrial flutter(AFL)globally and in China and Japan from 1990 to 2021,and to predict their future trends,aiming to provide references for health decision-making.Methods Based on the Global Burden of Disease Study Database 2021(GBD 2021),we extracted age-standardized prevalence rate(ASPR)and age-standardized disability-adjusted life year rate(ASDALYR)data for AF/AFL by sex globally,in China,and Japan.The estimated annual percentage change(EAPC)was used to assess the trends.Joinpoint regression analysis and the Bayesian age-period-cohort(BAPC)model were employed for trend analysis and prediction.Results From 1990 to 2021,the ASPR and ASDALYR for AF/AFL in males were increased significantly globally,with EAPC of 0.05(95%CI:0.01～0.08)and 0.09(95%CI:0.08～0.11),respectively.Changes were significantly declined in females,with EAPC of-0.11(95%CI:-0.14～-0.07)and-0.10(95%CI:-0.12～-0.07).In China,the ASPR for AF/AFL were increased in both males and females,with those of males more notably(EAPC=0.77,95%CI:0.65～0.88).However,the ASDALYR for AF/AFL showed gender divergence,with an increase in males(EAPC=0.40,95%CI:0.30～0.49)while a decrease in females(EAPC=-0.55,95%CI:-0.67～-0.44).In Japan,both the ASPR and ASDALYR for males and females showed continuous declines,and the reduction was more pronounced among females(ASPR EAPC=-1.77,95%CI:-2.32～-1.22;ASDALYR EAPC=-1.73,95%CI:-2.11～-1.35).Joinpoint regression analysis showed that from 1990 to 2021,for the ASDALYR of AF/AFL,the average annual percentage change(AAPC)was 0.28%(P<0.001)for Chinese males and-0.37%(P<0.001)for Chinese females,while the AAPC was-0.70%(P<0.001)and-1.43%(P<0.001)for Japanese males and females.BAPC model revealed that by 2036,the ASDALYR for Chinese males is predicted to increase from 91.45 per 100 000 in 2022 to 101.11 per 100 000,and for females is from 88.85 per 100 000 to 100.98 per 100 000.For Japanese males,the ASDALYR is projected to increase slightly from 88.79 to 89.86 per 100 000,while for females,it is projected decrease slightly from 41.13 to 39.67 per 100 000,indicating only minor fluctuations in the ASDALYR for both Japanese males and females.Conclusion The disease burden of AF/AFL continues to increase globally and in China.So,Japan's lifestyle and health policies are worth considering,and more scientific and effective public health policies and clinical intervention strategies should be formulated and implemented.Countermeasure The relevant government agencies should promote the transformation of the food industry through the policy-market mechanism,carry out activities related to national health management,and continuously optimize the AF/AFL management model of medical and health institutions to effectively cope with this disease burden change.

The Compilation Instructions for Expert Consensus on Clinical Application of Dieda Huoxue capsules systematically expound the development methods and evidence-based basis of this consensus. In view of the weak clinical application evidence and ambiguous indications of Dieda Huoxue capsules， the Institute of Basic Research in Clinical Medicine of the China Academy of Chinese Medical Sciences and Wangjing Hospital took the lead and collaborated with 33 experts from 28 medical institutions nationwide. They strictly followed the World Health Organization （WHO） guideline-making norms and the Grading of Recommendations Assessment， Development and Evaluations （GRADE） evidence-grading system and completed the compilation through multidisciplinary cooperation. The workflow included constructing clinical questions （19 items were screened by the nominal group technique）， retrieving evidence （from Chinese and English databases and grey literature）， assessing safety （integrating drug monitoring data and clinical investigations）， and forming recommendations and consensus suggestions （3 recommendations were reached via the GRADE grid method， and 16 consensus suggestions were reached by the majority vote rule）. The results indicate that the consensus clearly states that this medicine （Dieda Huoxue capsules） is applicable to conditions like traumatic injury， blood stasis-induced pain， and sudden lumbar sprains. The recommended dose is 6 capsules each time， twice a day. Combining oral administration with external application can enhance the efficacy， and elderly patients should take the medicine at intervals. Safety monitoring suggests that it should be used with caution in people with a bleeding tendency and those with an allergic constitution. The compilation process involved three rounds of reviews by internal and external experts. Literature analysis， the Delphi method， and clinical applicability tests were employed to ensure methodological rigor. The compilation instructions comprehensively present key aspects such as project approval and registration， conflict-of-interest statements， and evidence evaluation through 12 appendices， providing methodological support for the clinical translation of the consensus. In the future， it will be continuously improved through a dynamic revision mechanism.

Anxiety disorder is a major symptom of autism spectrum disorder (ASD) with a comorbidity rate of ~40%. However, the neural mechanisms of the emergence of anxiety in ASD remain unclear. In our study, we found that hyperactivity of basolateral amygdala (BLA) pyramidal neurons (PNs) in Shank3 InsG3680 knock-in (InsG3680^+/+) mice is involved in the development of anxiety. Electrophysiological results also showed increased excitatory input and decreased inhibitory input in BLA PNs. Chemogenetic inhibition of the excitability of PNs in the BLA rescued the anxiety phenotype of InsG3680^+/+ mice. Further study found that the diminished control of the BLA by medial prefrontal cortex (mPFC) and optogenetic activation of the mPFC-BLA pathway also had a rescue effect, which increased the feedforward inhibition of the BLA. Taken together, our results suggest that hyperactivity of the BLA and alteration of the mPFC-BLA circuitry are involved in anxiety in InsG3680^+/+ mice.

Objective: To observe the effect of Xipayimaizibizi oral liquid (XP) in an overactive bladder (OAB) experimental rat model and to explore its pharmacological mechanisms. Methods: Network pharmacology was used to explore the potential mechanisms of action of XP. The rats underwent bladder outlet obstruction surgery and were administered the corresponding drug concentrations by gavage for 4 weeks. The study observed the body weight, water intake, bladder and kidney indices (to evaluate their general status), urination behavior pattern (to observe frequency and urgency), and urodynamics (to measure bladder parameters). Hematoxylin and eosin and Masson's trichome staining were used to observe changes in the bladder structure. Enzyme-linked immunosorbent assay was used to measure the levels of nerve growth factor, brain-derived neurotrophic factor, and acetylcholine in the urine. The key targets involved in these mechanisms were validated using reverse transcription-quantitative polymerase chain reaction, immunohistochemistry, and western blot in vivo/vitro experiments. Result: Network pharmacological analysis predicted that XP may alleviate OAB by affecting the cholinergic synapse and calcium signaling pathways. XP treatment significantly reduced the bladder index, improved urine behavior and urodynamic parameters, decreased the neurotransmitters in urine, and reduced the thickness of the bladder wall and collagen ratio. These results indicate that XP can alleviate OAB symptoms and improve the bladder structure. In vivo/vitro experiments further demonstrated that XP can inhibit targets, such as muscarinic acetylcholine receptor 2, and participate in cholinergic synapses to further regulate the parasympathetic nervous system. It can also reduce the overexpression of Ca2+ caused by agonists, inhibit targets such as transient receptor potential vanilloid type 1, and participate in calcium signaling pathways to maintain Ca2+ homeostasis. Conclusion These results suggest that XP inhibited bladder overactivity by maintaining Ca2+ homeostasis and regulating the parasympathetic nervous system.

Poly(ADP-ribosyl)ation (PARylation) is a specific form of post-translational modification (PTM) predominantly triggered by the activation of poly-ADP-ribose polymerase 1 (PARP1). However, the role and mechanism of PARylation in the advancement of acute kidney injury (AKI) remain undetermined. Here, we demonstrated the significant upregulation of PARP1 and its associated PARylation in murine models of AKI, consistent with renal biopsy findings in patients with AKI. This elevation in PARP1 expression might be attributed to trimethylation of histone H3 lysine 4 (H3K4me3). Furthermore, a reduction in PARylation levels mitigated renal dysfunction in the AKI mouse models. Mechanistically, liquid chromatography-mass spectrometry indicated that PARylation mainly occurred in receptor for activated C kinase 1 (RACK1), thereby facilitating its subsequent phosphorylation. Moreover, the phosphorylation of RACK1 enhanced its dimerization and accelerated the ubiquitination-mediated hypoxia inducible factor-1α (HIF-1α) degradation, thereby exacerbating kidney injury. Additionally, we identified a PARP1 proteolysis-targeting chimera (PROTAC), A19, as a PARP1 degrader that demonstrated superior protective effects against renal injury compared with PJ34, a previously identified PARP1 inhibitor. Collectively, both genetic and drug-based inhibition of PARylation mitigated kidney injury, indicating that the PARylated RACK1/HIF-1α axis could be a promising therapeutic target for AKI treatment.

Objective:To analyze the cerebral hemodynamic characteristics of uremic patients complicated with depressive symptoms by transcranial color-coded Doppler(TCCD),and explore the correlation between cerebral hemodynamic indicators and uremia complicated with depressive symptoms.Methods:A total of 70 uremic patients received hemodialysis in our hospital from Dec 2022 to Dec 2023 were enrolled,in which 37 patients complicated with depressive symptoms were selected as the research group,and 40 patients without depressive symptoms were selected as the control group.Peak systolic velocity(PSV),end diastolic velocity(EDV),mean velocity(MV),and pulsatility index(PI)of bilateral middle cerebral artery(MCA)were compared.Binary logistic regression was used to analyze risk factors for uremia complicated with depressive symptoms,and receiver operating characteristic(ROC)curves were generated for key parameters.Results:There was no significant difference in PSV between the two groups(P＞0.05),while EDV and MV of bilateral MCA in the research group were lower but PI was higher than those in the control group(P＜0.05).Age was positively correlated with the depressive symptoms in uremic patients,while EDV,MV of bilateral MCA and left PSV were negatively correlated with depressive symptoms of uremic patients(P＜0.05).The elevated level of HCO3-in blood increased the risk of uremia complicated with depressive symptoms(OR=1.245,95%CI:1.024-1.513).When the left EDV was 41.25 cm/s,the predicted occurrence rate of depressive symptoms in uremic patients was 74.6%,with a specificity of 62%and a sensitivity of 85%.Conclusions:EDV and MV of bilateral MCA in patients with uremia complicated with depressive symptoms were lower than those in patients with uremia without depressive symptoms.Age,EDV and MV of bilateral MCA and PSV of left MCA were associated with depressive symptoms.Left EDV＜41.25 cm/s may serve as a hemodynamic marker for early clinical detection of depressive symptoms in uremia.TCCD can provide a reference for early clinical detection of uremic patients complicated with depressive symptoms.

Objective:To explore the impact of air pollution on hospital visits for mental and behavioral disorders among residents in an industrial area in Henan Province from 2016 to 2021.Methods:Daily outpatient visits data for mental and behavioral disorders were collected from Angang General Hospital in Angang Industrial Area at Anyang City between January 2016 and December 2021. And air pollutants and meteorological data during the same period were also collected. A generalized additive model was used for time-series analysis to examine the relationship between daily average concentrations of nitrogen dioxide (NO 2), sulfur dioxide (SO 2), fine particulate matter (PM 2.5), inhalable particulate matter (PM 10), carbon monoxide (CO), and ozone (O 3) with a lag of 0 to 7 days on the number of visits for mental and behavioral disorders among residents. The single-day lag effect (lag0-lag7 d) and cumulative lag effect (lag01-lag07 d) were analyzed. The smooth cubic spline function was used to fit the exposure-response relationship, and subgroup analysis was performed according to different genders, seasons and ages. Results:A total of 26 268 hospital visits for mental and behavioral disorders were collected from the industrial area between 2016 and 2021. The daily average concentrations of SO 2, NO 2, PM 2.5, PM 10, and CO were (27.50±27.33), (43.11±18.33), (73.87±60.30), (134.01±83.81) μg/m 3, and (1.72±1.03) mg/m 3, respectively. The daily maximum 8-hour average concentration of O 3 was (82.18±53.70) μg/m 3. After controlling for long-term trends, temperature, relative humidity, day of the week effects, and holiday effects, the generalized additive model analysis showed that NO 2 had a statistically significant impact on the hospital visits for mental and behavioral disorders at lag0 d, lag2 d and lag01-lag05 d and CO had a statistically significant impact at lag0-lag3 d and lag01-lag06 d (all P<0.05). NO 2 at lag02-lag04 d and CO at lag0-lag2 d and lag01-lag04 d had statistically significant effects on the visits for neurasthenia (both P<0.05). The impacts of NO 2 at lag03-lag04 d, PM 2.5 at lag3 d and lag03-lag04 d, PM 10 at lag3 d and lag03 d, and CO at lag3 d and lag01-lag05 d on visits for generalized anxiety disorder were also statistically significant (all P<0.05). After false discovery rate (FDR) correction, it was shown that for every 10 μg/m 3 increase in NO 2 and every 0.1 mg/m 3 increase in CO, the percentage increase in visits for mental and behavioral disorders and its 95% confidence interval (95% CI) were 3.38% (0.95%-5.87%) and 0.78% (0.38%-1.17%), respectively. For every 0.1 mg/m 3 increase in CO, the visits for neurasthenia increased by 0.78% (0.27%-1.29%). For every 10 μg/m 3 increase in PM 2.5 and every 0.1 mg/m 3 increase in CO, the visits for generalized anxiety disorder increased by 1.07% (0.46%-1.68%) and 1.17% (0.37%-1.97%), respectively (adjusted P<0.05). There was a linear exposure-response relationship between NO 2 and CO and the hospital visits for mental and behavioral disorders, CO and the hospital visits for neurasthenia, and CO and PM 2.5 and the hospital visits for generalized anxiety disorder ( P<0.05 for the overall association test and P>0.05 for the non-linearity test). Stratified analysis showed that air pollutants had an impact on male patients with neurasthenia, female patients with generalized anxiety disorder, individuals aged <45 years with mental and behavioral disorders, and individuals aged ≥65 years with generalized anxiety disorder. The impact of air pollutants was greater during the cold season or winter. Conclusion:Exposure to air pollution can increase hospital visits for mental and behavioral disorders among residents in industrial areas, with a higher risk among those aged<45 years old and during the cold season.
