With the rapid development of generative artificial intelligence(GAI)technologies,their widespread application in academic research and writing is continuously expanding the boundaries of sci-entific inquiry.However,this trend has also raised a series of ethical and regulatory challenges,inclu-ding issues related to authorship,content authenticity,citation accuracy,and accountability.In light of the growing involvement of AI in generating academic content,establishing an open,controllable,and trustworthy ethical governance framework has become a key task for safeguarding research integrity and maintaining trust within the academic community.This expert consensus outlines ethical requirements across key stages of AI-assisted academic writing-including topic selection,data management,citation practices,and authorship attribution.It aims to clarify the boundaries and ethical obligations surrounding AI use in academic writing,ensuring that technological tools enhance efficiency without compromising in-tegrity.The goal is to provide guidance and institutional support for building a responsible and sustainable research ecosystem.

Objective To explore the role of miR-204-3p in silicosis and to elucidate the mechanism by which it affects silicosis fibers by regulating silica dust-induced alveolar epithelial-mesenchymal transition(EMT)in rats.Methods Forty SD rats were divided randomly into 4 groups:Control,Silicosis,AAV-Control,and AAV-miR-204-3p groups.The pathology of lung tissue damage was detected by hematoxylin and eosin(HE)and Masson staining.Relative expression levels of miR-204-3p and EMT marker genes in lung tissues from rats in each group were analyzed by real-time fluorescence reverse transcription quantitative PCR(RT-qPCR),and protein expression levels of EMT-related markers in lung tissues were detected by Western blot.Results The alveolar structure was damaged,the lung septa showed interstitial fibrosis,and expression levels of mesenchymal markers were elevated in the Silicosis group compared with the Control group(P＜0.05,P＜0.01,P＜0.001).The alveolar structure was more complete,the EMT process was alleviated,fibrosis was improved,and mesenchymal marker expression was reduced in the AAV-miR-204-3p group compared with the AAV-Control group(P＜0.05,P＜0.01,P＜0.001).Conclusions Free silica dust induces EMT in rat lung tissue.Overexpression of miR-204-3p can attenuate the EMT process induced by free silica dust in rats,and may thus affect silicosis fibrosis.

Objective: To evaluate the accuracy of body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHtR) in screening true obesity among children, so as to provide a scientific basis for precise screening and early prevention and control of childhood obesity. Methods: A total of 1 322 children aged 10-15 years old were surveyed by the Huantai Children Cardiovascular Health Cohort in 2021. Fat mass percentage (FMP) and fat mass index (FMI) were measured by bioelectrical impedance analysis, with FMP or FMI values at or above the age and sex-specific 70th percentiles as the criteria for defining true obesity. BMI, WC and WHtR were used to define general obesity and central obesity. The accuracy of these measures in screening for true obesity was evaluated by calculating the missed diagnosis rate, misdiagnosis rate, area under the curve(AUC) for receiver operating characteristic and Kappa coefficient. Results: Boys had higher BMI [(21.79±4.56) kg/m 2], WC [(76.41±12.53) cm] and WHtR (0.47±0.07) than girls [(20.83±4.13) kg/m 2, (70.69±10.06) cm, (0.45±0.06)] ( t =4.02, 9.19, 6.63), while boys had lower FMP [(18.29±8.35)%] and FMI [(4.35±2.79) kg/m 2] than girls [(24.87±6.51)%, (5.44±2.53) kg/m 2] ( t =-16.10,-7.42) ( P <0.01). Using FMP as a reference standard, the diagnosis error rates of screening for true obesity based on BMI, WC and WHtR were 12.24%, 2.11% and 2.11%, respectively; the diagnosis error rates were 10.88%, 27.28% and 24.33%; the AUC values were 0.88, 0.85 and 0.87; the Kappa coefficients were 0.67, 0.48 and 0.52. Using FMI as a reference standard, rates of BMI, WC and WHtR screening for true obesity were 14.20%, 1.23% and 2.78%; the diagnosis error rates were 4.81%, 20.84% and 18.14 %; the AUC values were 0.90, 0.89 and 0.90; the Kappa coefficients were 0.81, 0.64 and 0.67. Conclusions BMI has a higher diagnosis error rate in screening for true obesity in children, while WC and WHtR have higher diagnosis error rates. It is recommended to promote body fat assessment in clinical practice, so as to achieve more accurate prevention and control of chronic diseases.

Objective:To explore the effect of Taichi motor imagination therapy combined with resistance exercise on the recovery of heart function and quality of life in patients with chronic heart failure(CHF).Methods:A total of 118 elderly CHF patients admitted to Huangshan Shoukang Hospital between January 2020 and December 2023 were included in this randomized controlled trial.Participants were randomly divided into intervention group(n=59)and control group(n=59).Participants in the control group received conventional anti-heart failure treatment,while those in the intervention group received additional Taichi motor imagination therapy and resistance exercise.The in-tervention lasted for 3 months.Cardiac function[left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDd)and interventricular septal thickness at diastole(IVSTd)],quality of life[Minnesota Living with Heart Failure Questionnaire(MLHFQ)],markers of heart failure and neurohormones[B-type natri-uretic peptide(BNP),norepinephrine(NE),aldosterone(ALD)and angiotensin Ⅱ(AngⅡ)]levels and the inci-dence of major adverse cardiovascular events(MACE)during intervention were compared between the two groups.Results:Compared to those in the control group,participants in the intervention group had significant higher LVEF[(50.52±1.96)％vs.(45.84±2.21)％],and significant lower LVEDd[(57.12±1.72)mm vs.(60.45±2.14)mm],IVSTd[(8.84±0.82)mm vs.(10.00±1.19)mm],MLHFQ score[(28.86±5.34)points vs.(34.51±6.57)points],BNP[(9.23±1.35)pg/ml vs.(13.62±1.49)pg/ml],NE[(13.09±0.93)pmol/L vs.(16.63±0.86)pmol/L],ALD[(1.82±0.12)ng/L vs.(2.35±0.15)ng/L],AngⅡ[(0.75±0.07)ng/L vs.(0.90±0.06)ng/L]and incidence of MACE(6.90％vs.26.32％)(P＜0.01 all).Conclusion:Taichi motor imagination therapy combined with resistance exercise may improve the cardiac function and quality of life in CHF patients.

Aim To explore the mechanism of the syn-ergistic effect of the ferroptosis inducer erastin com-bined with shikonin in promoting ferroptosis in human hypertrophic scar fibroblasts(HSFBs).Methods Hypertrophic scar tissues provided by the General Hos-pital of Ningxia Medical University were collected,and HSFBs were extracted.HSFBs were identified by HE staining and immunofluorescence.The inhibitory rates of Era and SHK on HSFBs at different concentrations were detected by CCK-8 assay,and the IC50 value was calculated.CompuSyn software was used to calculate the co-use index(CI).Control group,Erastin(Era)group,shikonin(SHK)group and Era+SHK group were set up,and the number and morphological chan-ges of cells were observed after 24 hours of interven-tion.The ability of cell migration and invasion was de-tected by scratch test and Transwell test.The changes of malondialdehyde(MDA),total iron ion and reactive oxygen species(ROS)were detected by corresponding biochemical kits.The expressions of collagen I,α-SMA and GOT1,SLC7A11,GPX4 and FTH1 were detected by Western blot.Results The IC50 value of Era and SHK of primary HSFBs was 2.22 μmol·L-1 and 3.94μmol·L-1 respectively,which was used as the single drug concentration for subsequent experiments.The CompuSyn software was employed to calculate the CI value when the two drugs were used in combination,and the concentrations corresponding to CI=0.39597(Era:1.2 μmol·L-1+SHK:1.5 μmol·L-1)were selected as subsequent combination concentrations(Because when CI was equal to 0.395 97,the concen-tration of each drug was lower than the concentration of single drug,and the inhibition rate of combined drug was greater than 50％).Compared with the monother-apy group,the number of HSFBs in the SHK+Era group was significantly reduced,cell membrane showed breakage and vesiculation,cell wrinkling became smal-ler,and cytoplasm was concentrated.The migration and invasion ability of HSFBs in the SHK+Era group were obviously weakened(P＜0.05),and the expres-sion of fibrosis-related proteins collagen Ⅰ and α-SMA was reduced(P＜0.05);the contents of MDA,total i-ron ions,and ROS in HSFBs of the SHK+Era group increased(P＜0.05),and the protein expression lev-els of SLC7A11,GOT1,GPX4,and FTH1 further de-creased(P＜0.05).Conclusions Erastin in combi-nation with shikonin can synergistically inhibit the pro-liferation,migration and fibrosis levels of HSFBs.The mechanism may be that erastin enhances the inhibition of shikotin on GOT1,increases the levels of cellular i-ron ions,ROS,and lipid peroxides,thereby promoting ferroptosis in HSFBs.

Objective To investigate the association between gut microbiota metabolite,trimethy-lamine-N-oxide(TMAO),and total imaging burden in diabetic patients with cerebral small vessel disease(CSVD).Methods A prospective study was conducted on 112 elderly diabetic patients with CSVD admitted in our hospital from June 2022 to May 2024.According to the total imaging burden score,they were divided into a high burden group(burden score≥2,57 cases)and a low burden group(burden score＜2,55 cases).High-performance liquid chromatography with online electrospray ionization tandem mass spectrometry was applied to detect the plasma level of TMAO.Then based on the tertile of plasma TMAO level,the patients were also assigned into low(＜2.44 μmol/L,38 cases),median(2.44 μmol/L≤TMAO＜5.18 μmol/L,37 cases)and high TMAO(≥5.18 μmol/L,37 cases)groups.ROC curve analysis was used to assess the predictive value of plasma TMAO level for high imaging burden in diabetic patients with CSVD.Binary logistic regression analysis was employed to analyze the correlation between plasma TMAO level and high imaging burden.Results The high burden group exhibited significantly higher plasma TMAO level than the low burden group(P=0.002).The AUC value of plasma TMAO level in predicting high imaging burden was 0.669(95％CI:0.569-0.769,P=0.002).The percentage of high imaging burden was 34.2％,54.1％and 64.9％,respectively among the low,median and high TMAO groups,with significant differences among them(Chi-square=7.270,P=0.026).Binary logistic regression analysis indicated the correlation between TMAO and high imaging burden(OR=1.178,95％CI:1.019-1.364,P=0.027).Conclusion In elderly diabetic patients with CSVD,plasma TMAO level is closely associated with high imaging burden,with higher TMAO level,higher risk for high imaging burden.

Objective To explore the correlation between gait disorders and alterations in diffusion tensor imaging(DTI)parameters in different regions of interest(ROI)and associated white matter tracts in older patients with leukoaraiosis(LA).Methods A total of 108 elderly LA patients admitted in our department from July 2023 to May 2024 were enrolled,and based on the Fazekas scale,they were divided into normal(n=28),moderate(n=48),and severe groups(n=32).Tinetti Gait Scale(TGS)was used to evaluate the morbility and balance function,and Short Physical Performance Battery(SPPB)was employed to assess motor function.All participants underwent brain MRI and DTI scanning.Fractional anisotropy(FA)values were quantitatively measured in predefined ROIs and specific white matter tracts.Results The moderate and severe groups had significantly advanced age and higher homocysteine level,and lower total TGS score,Tinetti gait score,total SPPB score,and walking speed score than the normal group(P＜0.05).The severe group exhibited obviously lower education level,and decreased Tinetti balance score and standing score than the normal and moderate groups(P＜0.05).The FA values at the left pa-rietal lobe,the anterior horn of bilateral lateral ventricles,and the splenium of the left corpus cal-losum were notably lower,so were the FA values at the corpus callosum(left-right),left cortico-spinal tract(inferior segment),left anterior thalamic radiation(inferior segment),left inferior fronto-occipital fasciculus(inferior segment),and left superior longitudinal fasciculus(inferior segment)in the moderate group and the severe group than the normal group(P＜0.05).The se-vere group demonstrated lower FA values at the left and right parietal lobes than the other two groups(P＜0.05).Multivariate logistic regression analysis revealed that the anterior horn of the left lateral ventricle(β=-0.683,P=0.001)and the left inferior corticospinal tract(β=-0.742,P=0.001)were influencing factors for gait disorder in elderly LA patients.Conclusion In elderly LA patients,gait disorders are correlated with decreased FA values in specific ROI and white mat-ter tracts,with the decreased FA values in the anterior horn of the left lateral ventricle and the left inferior corticospinal tract demonstrating the most significant impact.

Cilia,as cellular sensory organelles,actively partici-pate in and regulate cellular processes such as autophagy and metabolic breakdown during their generation and transportation.Autophagy,on the other hand,is a cell self-protection mecha-nism that maintains cellular homeostasis by clearing aggregates and damaged organelles.Combining recent research findings,this review comprehensively elucidates the bidirectional crosstalk between primary cilia and autophagy.Specifically,it highlights the crucial role of cilia-dependent signaling pathways in activa-ting cellular autophagy and how autophagy regulates cilia genera-tion and length by degrading specific ciliary proteins.Moreover,the dysregulation of primary cilia and autophagy is closely asso-ciated with the clinical manifestations and pathogenesis of vari-ous ciliopathy-related diseases such as polycystic kidney disease and tuberous sclerosis.In terms of pharmacotherapy,this review provides a comprehensive and in-depth overview of small mole-cule inhibitors targeting ciliogenesis,including cytoskeletal drugs and Hedgehog signaling pathway inhibitors.Despite the current limitations in clinical use,these drugs lay the groundw-ork for developing highly specific targeted small molecule inhibi-tors of ciliogenesis and for the treatment of ciliopathies and canc-ers.By systematically discussing ciliogenesis,autophagy,disea-ses and drugs,this review offers new insights for further elucida-ting the crosstalk between ciliogenesis and autophagy,exploring their pathological mechanisms in disease development,and de-veloping therapeutic strategies in the future.

AIM:To explore the role and mechanism of calcium-sensing receptor(CaSR)in regulating macro-phage polarization in hypertensive rats.METHODS:Male spontaneously hypertensive rats(SHR)and Wistar-Kyoto(WKY)rats were categorized into WKY group,SHR group,SHR+R568(CaSR agonist)group,and SHR+NPS2143(CaSR inhibitor)group.The thoracic aorta was isolated,and the expression of CaSR and macrophage polarization markers in the aorta was observed through immunofluorescence staining.The primary peritoneal macrophages of SHR and WKY rats were aseptically extracted following anesthesia.After intervention with R568 and NPS2143,the expression levels of M1 and M2 markers of peritoneal macrophages were observed by Western blot and immunofluorescence staining.The levels of interleukin(IL)-1β and IL-10 were measured by ELISA.The concentration of Ca2+in peritoneal macrophages was mea-sured by immunofluorescence.Western blot was employed to identify the expression of CaSR and nucleotide-binding oligo-merization domain-like receptor protein 3(NLRP3)inflammasome components.Following anesthesia,vascular smooth muscle cells(VSMCs)were isolated from SHR using an adherent method.Subsequently,a co-culture system was estab-lished with macrophage supernatant.The optimal action time for this co-culture system was determined through CCK-8 as-say.RESULTS:Compared with SHR group,activation of CaSR resulted in a significant decrease in the protein expres-sion of M1 polarization markers(P<0.05)and a concomitant increase in the protein expression of M2 polarization markers in the aorta(P<0.05).Compared with SHR group,administration of R568 led to a significant decrease in the protein ex-pression of M1 polarization markers(P<0.05)and a concomitant increase in the protein expression of M2 polarization markers(P<0.05)in peritoneal macrophages.Additionally,there was a notable reduction in the protein levels of NLRP3 inflammasome components(P<0.05).Furthermore,the fluorescence intensity of intracellular Ca2+was significantly en-hanced following R568 treatment(P<0.05).After administration of MCC950,an NLRP3 inflammasome inhibitor,the re-sults were consistent with those observed following R568 treatment,demonstrating statistical significance(P<0.05).This effect was reversed by the combined intervention of U73122,a phospholipase C(PLC)inhibitor(P<0.05).Compared with the control(0 h),the 24-h peritoneal macrophage supernatant exhibited the strongest capacity to enhance the viabili-ty of VSMCs after 24 h of culture(P<0.05).CONCLUSION:In hypertensive rats,the CaSR inhibits NLRP3 inflamma-some activation via the PLC-Ca2+signaling pathway,thereby mediating an increase in macrophage polarization towards the M2 phenotype and a decrease towards the M1 phenotype.
