Objective To investigate the cross-sectional associations between different fatty liver classifications and cardiac structure and function in people undergo health examination. Methods A total of 6 545 adults who underwent health examinations at the Health Management Center of Zhongshan Hospital, Fudan University between January 1 and December 31, 2017, were retrospectively included. Demographic characteristics and laboratory data were collected. The hepatic steatosis was graded by ultrasonography. And patients with fatty liver were further stratified according to alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels, as well as the degree of liver fibrosis. Cardiac morphology and function were assessed by transthoracic echocardiography, and left ventricular geometric patterns were classified accordingly. Multivariate logistic regression analysis was performed to evaluate the associations between fatty liver classifications and cardiac abnormalities. Results There were 2 795 patients (42.7%) with fatty liver, of whom 832 (29.8%) had significant cardiac structural alterations and 1 500 (53.7%) had diastolic dysfunction. Severe fatty liver was risk factor for concentric remodeling and increased relative wall thickness (RWT), with odds ratios (ORs) of 1.27 (P＝0.012) and 1.27 (P＝0.009), respectively. Fatty liver accompanied by elevated ALT or AST was risk factor for concentric remodeling (OR＝1.45,1.56; P＝0.001, 0.001), increased RWT (OR＝1.48,1.57; P＜0.001, ＜0.001), and diastolic dysfunction (OR＝1.27, 1.32; P＝0.035, 0.040), respectively. Fatty liver with liver fibrosis was risk factor for concentric remodeling (OR＝1.83, P＝0.046) and diastolic dysfunction (OR＝2.64, P＝0.034). Conclusions Advanced fatty liver, including severe hepatic steatosis, accompanied by elevated liver enzymes or liver fibrosis, could increase risks of cardiac remodeling and diastolic dysfunction, while systolic function is preserved. For patients with fatty liver, it is recommended to undergo regular ultrasonography examination.

OBJECTIVE To establish an integrated central pharmacy management model combining the inpatient pharmacy and the pharmacy intravenous admixture service （PIVAS）， and to evaluate its effectiveness and economic value in terms of operational cost composition， dispensing output， and dispensing efficiency.METHODS Through spatial integration， flexible staff scheduling， the application of intelligent equipment， and a dual prescription review system， the inpatient pharmacy and PIVAS were integrated， and an integrated management model was implemented. Operational data from the Fourth Affiliated Hospital of Soochow University （hereinafter referred to as “our hospital”） in 2023 were selected for analysis， with national median data and data from another hospital in the same region that still implemented a separate management model for the inpatient pharmacy and PIVAS serving as controls. The activity-based costing method was used to calculate operating costs. Dispensing output， dispensing efficiency， and unit activity cost were compared among the three. Cost-benefit analysis was further conducted by calculating the net benefit （NB） and the incremental cost-effectiveness ratio （ICER） for economic evaluation.RESULTS Under the integrated central management model， the total operational cost of our hospital’s central pharmacy was 3.968 3 million yuan， representing an 11.80% reduction compared with the external hospital’s pharmacy （4.499 0 million yuan）， with consumable costs and labor costs decreasing by 38.73% and 10.99%， respectively. The total prescription dispensing volume （3.613 4 million orders） was 43.58% higher than that of the external hospital’s pharmacy （2.516 7 million orders）. The daily dispensing volume per capita reached 471.41 medication orders， 3.5 times that of the external hospital’s pharmacy （135.20 medication orders）. The unit activity cost was 1.10 yuan， showing a 38.55% decrease relative to the external hospital’s pharmacy （1.79 yuan）. The NB was 755 200 yuan， and the ICER was －2.36. In terms of PIVAS operations， the daily dispensing volume per capita for general infusions （including antibacterial drugs） in our hospital was 50.83 sets， higher than the national PIVAS median （49.11 sets） and the external hospital pharmacy （36.14 sets）； the daily dispensing volume per capita for hazardous drugs was 0.86 sets， higher than the national median （0.70 sets） and the external hospital pharmacy （0.16 sets）.CONCLUSIONS The integrated central pharmacy management model established by our hospital achieved reduced operational costs and enhanced staff efficiency despite growing service volumes. Integrating the functions of both the inpatient pharmacy and the PIVAS， this model outperformed national medians and peer hospitals in dispensing output， dispensing efficiency， unit activity cost control， and economic evaluation， and surpassed the national median specifically in PIVAS dispensing efficiency.

Objective To establish the phylogenic relationships among genus Botrychium,and to develop better molecular markers,along with to gain better understanding of cytonuclear coordination patterns of RuBisCO enzyme,the current article sampled two species(e.g.Botrychium ternatum(Thunb.)Sw.and Botrychium virginianum(L.)Sw.),and applied sequencing approaches for the data mining.Methods The assembly results of chloroplast(cp)genomes from B.ternatum and B.virginianum were determined via de novo hybrid assemble approach with the help of short reads(Illumina)and long reads(PacBio and Nanopore).Then the phylogenic relationships of 18 fern species were reconstructed based on the protein coding sequences from the cp genome and the rbcS gene,which were fished out of the RNA-seq data from SRA database,respectively.Then the adaptive selection and co-evolutionary analysis were employed to investigate the evolutionary trajectories of rbcL(cp genome)and rbcS(nuclear genome)genes.Results The full length of cp genome in the two genus Botrychium species were determined as 139 063 bp(NC_060644)and 139 372 bp(OR609363).Then 92 SSR sites and 78 SSR sites were identified in the current two cp genomes,respectively.The collinearity analysis showed high relevant relationship between the current two species,and significant relationship within both species among the inverted repeats regions.The adaptation and coevolution investigations illustrated the following results:①Coevolution network exists between RBCL and RBCS subunits from the fern RuBisCO enzyme.②Positively selected sites were significantly detected among both rbcL and rbcS genes.③Two coevolutionary pair sites from the two genes(e.g.site 11 in RBCL and site 106 in RBCS)were significantly positively selected,which may demonstrate a molecular pattern for the fern species fine-tuning the RuBisCO enzyme during the long earth history via the cytonuclear coordination.Conclusion Our current research shed a new light on the phylogenetic relationship of the genus Botrychium among the fern backbone-tree and provided amount of cpSSR sites with the potential as molecular markers for further population study on B.ternatum and B.virginianum.Moreover,our adaptation and coevolution investigations on rbcL and rbcS genes might indicate that the underlying cytonuclear coordination between the organelle and nuclear in cell of fern species for fine-tuning the key photosynthesis enzyme RuBisCO to gain better fitness according to the changing environment of earth during the geologic time-scale.

Objective:To explore the association between cardiometabolic multimorbidity(CMM), the number of cardiometabolic diseases(CMD)and mild cognitive impairment(MCI)among the older adults in urban communities.Methods:Based on the baseline data of the Hubei Memory and Aging Cohort Study(HMACS)from 2018 to 2023, CMM was defined as the coexistence of two or more CMDs(Type 2 diabetes, stroke and ischemic heart disease). Multivariate logistic regression was employed to examine the association between CMM, the number of CMDs and the prevalence of MCI, as well as subgroup heterogeneity.Results:This study included 6 113 urban participants aged ≥65 years(55.6% were female; mean age 71.9±5.7 years). The prevalence of MCI was 19.3%, with an increasing trend observed as the number of CMD increased(17.7%, 20.5%, 24.6%, 28.3%). After adjusting for all variables, a significant association was observed between CMM group and the prevalence of MCI( OR: 1.24, 95% CI: 1.01-1.52)compared with the non-CMM group.As the number of CMD increased, the prevalence of MCI increased( Ptrend=0.011), but the association was only significant in the group with two CMDs.Subgroup analyses revealed that in males( OR: 1.48, 95% CI: 1.10-2.00), those with more than 9 years of education( OR: 1.52, 95% CI: 1.15-2.02), and those with hypertension( OR: 1.33, 95% CI: 1.05-1.67), CMM was significantly associated with MCI, and the association with MCI increased significantly with the increase in the number of CMDs(all Pfor trend <0.05). Conclusions:Among urban community-dwelling older adults aged ≥65 years in China, CMM and the cumulative number of CMDs are significantly associated with an increase of MCI, particularly in males, those with higher education levels, and those with hypertension.In the future, the need for enhanced MCI screening for CMM patients should be strengthened, and targeted prevention and control of cognitive impairment should be implemented for high-risk populations.

Objective:To analyze the effect of precipitation on road traffic injuries (RTI) in Zhejiang Province.Methods:The RTI surveillance and meteorological data from 2009 to 2022 in Zhejiang Province were collected. Based on the time-stratified case-crossover design, the precipitation of case day and control day was compared, and the distributed lag nonlinear model was applied to analyze the correlation of precipitation and RTI. Stratified analyses were conducted to analyze the effect modification of gender, age, injury location, and temperature. An attributable fraction was used to assess the burden of RTI caused by precipitation.Results:A total of 239 970 RTIs were monitored in Zhejiang Province from 2009 to 2022, averaging 46 daily cases. The distributed lag nonlinear model showed that compared with no rain, the risk of RTI increased first and then decreased with the increase of precipitation. The risk of RTI was the highest when the precipitation was 30.99 mm ( OR=1.08, 95% CI: 1.05-1.11). The adverse effects on RTI mainly occurred on the day of precipitation, and it showed insignificant or protective effects with the extension of lag days. 1.34%(95% CI: 1.31%-1.36%) of RTI could be attributed to precipitation. Stratified analysis showed that gender, age, injury location, and temperature may modify the effect of precipitation on RTI. Precipitation caused a heavier burden on RTI in subgroups aged 18-64, females, and occurring on roads and in low temperatures. Conclusions:Precipitation can increase the risk of RTI. People aged 18-64 or females are the key groups for RTI prevention, and prevention and control efforts of precipitation-related RTI should be increased in road and low-temperature environments.

Objective To investigate the impact of inhibiting GATA binding protein 4(GATA4)on the susceptibility to atrial fibrillation in elderly individuals and to elucidate the underlying mecha-nisms.Methods Fifteen 3-month-old young SD rats and 45 18-month-old SD rats were selected.According to the age and the injection of adeno-associated virus,the rats were divided into young group,elderly group,negative control group and interfering GATA4 group,with 15 rats in each group.Based on age and AAV injection,the rats were categorized into four groups:young group,elderly group,negative control group,and GATA4 interference group,with 15 rats in each group.Left atrial anteroposterior diameter was assessed via echocardiography.The extent of atrial fibro-sis was evaluated using Masson staining.Western blot analysis was employed to examine the ex-pression levels of GATA4,calcium cycling-related proteins,and NOD-like receptor pyrin domain-containing protein 3(NLRP3).Mouse atrial myocytes(HL-1 cells)were divided into five groups according to viral infection:control group,knockdown negative control group,GATA4 knock-down group,overexpression negative control group,and GATA4 overexpression group.The expression of GATA4 and NLRP3 was analyzed using Western blotting.Results The incidence of atrial fibrillation in the elderly group was significantly higher than that in the young group(80.0％vs 11.1％,P＜0.01).Compared with the negative control group,the induction rate of atrial fibrillation in the GATA4 interference group was significantly decreased(22.2％vs 80.0％,P＜0.05).Compared with the young group,the left atrial diameter,percentage of collagen vol-ume,activation time,absolute value of conduction dispersion,and expression of NLPR3 in the aged group were significantly increased,and the expression of calcium cycling protein was disor-dered(P＜0.05,P＜0.01).Compared with the negative control group,the left atrial diameter,per-centage of collagen volume,activation time,absolute value of conduction dispersion,and expres-sion of NLPR3 in the GATA4 interference group were significantly decreased,and the disturbance of calcium circulation was alleviated(P＜0.05,P＜0.01).Compared with the negative group of knockdown and overexpression,the expression of GATA4 and NLRP3 in HL1 cells in GATA4 knockdown group was significantly decreased,and the expression of GATA4 and NLPR3 in HL-1 cells in GATA4 overexpression group was significantly increased(P＜0.01).Conclusion GATA4 inhibition decreases the susceptibility to atrial fibrillation and mitigates age-related structural remodeling,electrical remodeling,and inflammation in the atrium by regulating calcium cycling disorders and myocardial cell senescence via the NLRP3 pathway.

Background::The prevalence of type 2 diabetes mellitus (T2DM) has been rapidly growing in Chinese populations in recent decades, and the shift in eating habits is a key contributing factor to this increase. Eating out of home (EOH) is one of the major shifts in eating habits during this period. However, the influence of EOH on the incidence of T2DM among Chinese urban workers is unknown.Methods::The cross-sectional study involved an analysis of 13,904 urban workers recruited from 11 health examination centers in the major cities of China to explore the relationship between EOH and T2DM between 2013 September and 2016 March.Results::Average weekly EOH frequency ≥10 times was positively associated with increased incidence of T2DM in the sampled population (OR: 1.31 [1.11-1.54], p < 0.01), most notably in participants ≤45 years old (OR: 1.41[1.11-1.80], p < 0.01]) and in males (OR:1.26 [1.06-1.51], p < 0.01). An EOH frequency of 5 times/week appears as a threshold for a significant increase in the odds of T2DM. Weekly EOH frequency ≥5 times was associated with increased odds of T2DM in a dose-response manner in the total population and almost all subgroups ( poverall association < 0.05 and pnonlinearity ≤ 0.05). Conclusion::This study showed that a frequency of EOH (≥5 times/week) was associated with a frequency-dependent increase in the odds of T2DM urban workers in China. More nutrition promotion is needed to improve the eating behavior of Chinese urban workers to reduce T2DM risk.

Objective:To investigate the effects and mechanisms of dendrobium officinale polysaccharides(DOP)on neural function and sleep in a rat model of ischemic stroke.Methods:Rats with ischemic stroke were modeled using middle cerebral artery occlusion(MCAO).The neurological function was assessed using the Longa scale.Sleep was monitored by electroencephalography.The hippocampal tissue damage was evaluated by TTC staining,HE staining,Nissl staining and TUNEL staining.The kits were used to detect reactive oxygen species(ROS),malondialdehyde(MDA),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),IL-1β,and IL-18 in the hippocampal tissue.West-ern blot analysis was conducted to detect the expression of microtubule-associated protein light chain 3(LC3)and Bec-lin1,NLRP3,apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),cleaved caspase-1(C-caspase-1),GSDMD-N-terminal domain(GSDMD-N),nuclear factor erythroid 2-related factor 2(Nrf2),and heme oxygenase-1(HO-1)in the hippocampal tissue.Results:DOP can improve sleep quality and neurological func-tion in rats with ischemic stroke,alleviate hippocampal tissue damage,inhibit oxidative stress and inflammation in the hippocampus,decrease the expression of Beclin1,NLRP3,ASC,C-caspase-1,GSDMD-N,cytosolic Nrf2 protein,and the LC3-Ⅱ/LC3-Ⅰ ratio in the hippocampus,while increasing the expression of HO-1 and nuclear Nrf2 protein.The Nrf2 inhibitor ML385 partially reversed the ameliorative effects of DOP.Conclusion:DOP may improve neurological function and sleep in rats with ischemic stroke by inhibiting autophagy and NLRP3 inflammasome-mediated pyroptosis through the activation of the Nrf2/HO-1 pathway,thereby alleviating oxidative stress and neuroinflammation.

Objective To explore the characteristics of the inhibitory effect of Evodiamine on the proliferation of activated T cells. Methods Mononuclear cells from peripheral blood (PBMCs) were obtained from healthy donors through density gradient centrifugation, and T cells were subsequently purified by using immunomagnetic bead separation. T cell activation was induced by employing anti-human CD3 and anti-human CD28 antibodies. T cells were treated with different concentrations of EVO (0.37, 1.11, 3.33, and 10)μmol/L. Flow cytometry was applied to evaluate the proliferation index, apoptosis rate, viability, CD25 expression levels, and cell cycle distribution of T cells. The expression levels of cytokines IL-2, IL-17A, IL-4, and IL-10 were quantified by using ELISA. Results 1.11, 3.33 and 10 μmol/L EVO effectively inhibited the proliferation of activated T cells, with an IC₅₀ of (1.5±0.3)μmol/L. EVO did not induce apoptosis in activated T cells and affect the survival rate of resting T cells. EVO did not affect the expression of CD25 and the secretion of IL-2 in activated T cells. EVO arrested the T cell cycle at the G2/M phase, resulting in an increase in G2/M phase cells, and exhibited a concentration-dependent effect. EVO did not affect the secretion of IL-4, IL-10 by activated T cells, but significantly inhibited the secretion of IL-17A. Conclusion EVO did not significantly affect the activation process of T cells but inhibited T cell proliferation by arresting the cell cycle at the G2/M phase and significantly suppressed the secretion of the pro-inflammatory cytokine IL-17A, which suggests that EVO has the potential to serve as a lead compound for the development of low-toxicity and high-efficiency immunosuppressants and elucidates the mechanisms underlying the anti-inflammatory and immunomodulatory effects of the traditional Chinese medicine Evodia rutaecarpa.
