Atherosclerosis is a complex pathological condition resulting from lipid deposition， chronic inflammatory responses， and fibrosis， with a prolonged disease course and multifactorial etiology. Based on the traditional Chinese medicine （TCM） theory of accumulation syndrome， atherosclerosis can be classified under this category， with its pathogenesis involving phlegm， blood stasis， deficiency， and accumulation. This paper proposed a stage-based intervention strategy using the four therapeutic principles of "attacking， supplementing， dispersing， dissipating"， and divided into six stages based on the pathological progression， including the stage of accumulation before formation， the stage of accumulation already formed， the stage of nucleus accumulation， the stage of nucleus accumulation decay， the stage of nucleus accumulation consolidation， and the stage of severe stenosis of nucleus. At different stages， the intervention focuses on reinforcing healthy qi and consolidating the root， tonifying the kidneys and spleen， dispersing and removing turbidity， removing phlegm stagnation， promoting qi circulation， dispersing accumulations and removing stasis， attacking accumulation and expelling stasis， directing the turbid downward and dispersing accumulation， and treatment would be adjusted based on specific symptoms， which provides a theoretical framework for the prevention and treatment of atherosclerosis with TCM.

BackgroundMigraine is a common chronic neurological disease， and patent foramen ovale （PFO） has been closely associated with migraine. Current research primarily focuses on the pathological mechanism and the therapeutic effects of interventional closure， with limited attention paid to the impact of PFO on sleep quality in migraine patients. ObjectiveTo compare the difference in sleep quality between PFO-positive and PFO-negative migraine patients， and to analyzes influencing factors of sleep quality in PFO-positive migraine patients， so as to provide references for clinical interventions to improve sleep quality in PFO-positive migraine patients. MethodsA total of 673 migraine patients who met the diagnostic criteria of migraine in the International Classification of Headache Disorders， third edition （ICHD-3）， and all patients underwent contrast-enhanced transcranial Doppler （c-TCD） and transthoracic echocardiographic right heart contrast echocardiography （cTTE） in the Third Hospital of Mianyang from January 2020 to October 2024. Basic demographic data were collected using a self-designed questionnaire， headache severity was assessed with the Visual Analogue Scale （VAS）， and sleep quality was invaluated using the Pittsburgh Sleep Quality Index （PSQI）. PFO patients was diagnosed through c-TCD combined with c-TTE. Binary logistic regression analysis was employed to examine the influencing factors of sleep quality in PFO-positive migraine patients. ResultsA total of 673 （100.00%） migraine patients were enrolled， including 223 PFO-positive cases （33.14%） and 450 PFO-negative cases（66.86%）. The PFO-positive group showed significantly more severe headache severity （χ²=15.799， P<0.01） and poorer sleep quality （χ²=14.377， P<0.01） compared with PFO-negative group. PFO-positive patients demonstrated significantly higher barrier factor scores of sleep quality， sleep latency， sleep efficiency， sleep disturbance， hypnotic medication use， and daytime dysfunction compared with PFO-negative counterparts （t=3.634， 3.269， 2.785， 3.428， 2.907， 3.637， Bonferroni adjust P<0.05/7=0.007）.By contrast， no significant difference was noted in sleep duration scores between the two groups（t=2.349， Bonferroni adjust P>0.05/7=0.007）.The Binary Logistic regression analysis revealed that age （OR=1.021， 95% CI： 1.001~1.041）， headache severity （OR=6.030， 95% CI： 4.085~8.901）， and PFO grade （OR=1.893，95% CI： 1.288~2.784）were significant influencing factors for sleep quality in migraine patients with PFO. ConclusionMigraine patients with PFO-positive exhibited poorer sleep quality compared wtih PFO-negative patients. Older age， higher headache servity， and more severe PFO grade are identified as risk factors for impaired sleep quality in PFO-positive migraine patients.

In the era of big data, neuroimaging and algorithmic analyses have propelled brain science research and brain mapping. Acupuncture, widely recognized as an effective surface stimulation therapy, has demonstrated therapeutic efficacy for various brain conditions such as stroke and depression. However, the mechanisms linking acupuncture to brain function and its modulatory effects on brain activity require systematic exploration. Additionally, there is an urgent need to scientifically reinterpret traditional meridian theory and enhance its clinical applicability. Therefore, we propose the initiative of constructing a "brain mapping atlas of meridian, collateral and body surface stimulation" to explore the patterns linking the therapeutic effects of stimulating the twelve meridians, eight extraordinary vessels, divergent channels, collateral channels, sinew channels, and skin regions to brain function. This initiative aims to provide a scientific interpretation of traditional Chinese medicine meridian theory and enhance its practical applicability. This paper begins by reviewing the current state of brain mapping. It then summarizes existing research on the relationship between acupuncture and the brain, highlighting the necessity of constructing this atlas. The paper further analyzes the methodologies and technical challenges involved. Finally, the potential applications of the brain mapping atlas of meridian, collateral and body surface stimulation, and its main significance in advancing traditional meridian theory to keep pace with the times are prospected.

Objective To identify the disease burden and indirect economic burden caused by lung cancer in Kunshan City, Jiangsu Province, from 1981 to 2020. Methods The incidence and death cases of lung cancer were obtained from cancer registry and death cause monitoring data. The disability adjusted life years (DALY) was used as the evaluation index for burden posed by lung cancer on health, and the indirect economic burden was calculated by a human capital method. Results From 1981 to 2020, a total of 9272 deaths due to lung cancer were reported in Kunshan, of which 7106 were males and 2166 were females. The DALY caused by lung cancer in the whole population were 3.81, 4.14, 4.38, and 9.46 in 1981–1990, 1991–2000, 2001–2010, and 2011–2020, respectively. The indirect economic burden caused by lung cancer was 10.515, 141.657, 813.794, and 6659.149 million yuan. From 2011 to 2020, the ratios of years of life lost due to premature mortality to DALY in males, females, and the general population were 92.42%, 95.15%, and 93.60%, respectively. Conclusion The health burden and indirect economic burden for lung cancer are substantial in the Kunshan City. Moreover, age-specific DALY and indirect economic burden are not exactly symmetrical, suggesting that an effective control strategy to lower cost is urgently needed, especially for individuals aged 40-59.

Post-stroke depression is a common complication after a stroke. Based on the theory of ＂deficiency of heart qi leading to sadness＂recorded in Huangdi Neijing, our team proposes that deficiency of heart qi is the basic pathogenesis of post-stroke depression, with sadness being its main manifestation. Therefore, we advocate treating post-stroke depression from the perspective of the heart, and clinically, it can be divided into four stages: heart-liver stage, heart-lung stage, heart-spleen stage, and heart-kidney stage. Treating post-stroke depression with the principle of regulating qi and nourishing the heart, patients in the heart-liver and heart-lung stages are mainly middle-aged and young adults, with a pathological nature of qi stagnation and mild deficiency of heart qi, and therefore, the method of promoting the flow of meridians and regulating qi should be adopted. In contrast, patients in the heart-spleen and heart-kidney stages are mainly middle-aged and elderly, with a pathological nature of qi deficiency and severe deficiency of heart qi, and therefore, nourishment and tonification should be prioritized. In response to the above four stages, our team has achieved good clinical efficacy by administering Xiaoyao Powder, Baihe Dihuang Decoction, Ganmai Dazao Decoction and Jingui Shenqi Pill respectively. This study discusses the approach to treating post-stroke depression from the perspective of a "deficiency of heart qi leading to sadness" by examining three aspects: the theoretical basis of Chinese and Western medicine to treat post-stroke depression from the heart, the basic pathogenesis and staging of post-stroke depression, and the treatment principle of regulating qi and nourishing the heart. The study also briefly analyzes the clinical experience of the medications used for this condition to provide a reference for the treatment of post-stroke depression.

Objective To explore the effect of astilbin(astilbin-CS-NPs)-loaded chitosan nanoparticles(CS-NPs)on high glucose(HG)-induced ferroptosis of renal tubular epithelial cells via regulating mitogen-activated protein kinase 14(MAPK14)/heat shock protein 27(HSP27).Methods HK-2 cells were divided into the following groups:normal glucose(NG)group,HG group,HG+astilbin-CS-NPs(0,5,10,20 mg/L)group,and under HG condition,pcDNA3.1-MAPK14 group,pcDNA3.1-MAPK14+astilbin-CS-NP group,si-HSP27 group,pcD-NA3.1-MAPK14+si-HSP27 group,and pcDNA3.1-MAPK14+si-HSP27+astilbin-CS-NPs group.Cell viability was detected using CCK-8 assay,cell apoptosis was detected via Tunel assay.Meanwhile,iron ion levels,lactate dehydrogenase(LDH)activity,glutathione(GSH)levels,and reactive oxygen species(ROS)levels were meas-ured using assay kits.Rat model of diabetic kidney disease(DKD)was constructed and intervened with astilbin-CS-NPs to explore the effects of astilbin-CS-NPs on DKD in vivo.Results Compared with the NG group,the HK-2 cell viability in the HG group was significantly reduced,apoptosis increased,iron ion levels,LDH activity,and ROS levels were significantly elevated,while GSH levels significantly decreased(all P＜0.05).Treatment with astilbin-CS-NPs significantly reversed the effects of HG on the biological behavior of HK-2 cells and ferroptosis-re-lated indicators.Additionally,compared to the pcDNA3.1 group,the pcDNA3.1-MAPK14 group showed increased ferroptosis,which was improved by knocking down HSP27 or co-intervention with astilbin-CS-NPs.In vivo experi-mental results showed that astilbin-CS-NPs could improve DKD rat kidney injury,inhibit iron ion levels and the ex-pression of MAPK14/HSP27.Conclusion Astilbin-CS-NPs may improve HG-induced ferroptosis of renal tubular epithelial cells via inhibition of MAPK14 and HSP27 expression.

Objective To observe the value of energy spectrum CT angiography(CTA)optimal single energy imaging combined with adaptive statistical iterative reconstruction V(ASIR-V)for optimizing visualization of thoracodorsal artery(TDA).Methods Energy spectrum CTA was prospectively performed in 60 patients to observe TDA.The images were reconstructed as 120 kVp-like combined with 40%post-set ASIR-V(group A),as well as totally 18 kinds of single energy images ranging from 45 to 70 keV(with interval of 5 keV)combined with 40%,60%and 80%post-set ASIR-V(group B),and the subjective and objective evaluation results of the images were compared between and within groups.Results Under the same post-set ASIR-V weight,significant differences of subjective scores of axial and 3D images were found among different keV levels(all P＜0.001).With the increase of keV level,subjective scores of axial images increased first and then decreased,among which subjective score of 50 keV was the highest(all P＜0.001).Under the same keV levels,with the increase of ASIR-V weight,the subjective scores of overall axial images and 3D images for displaying the main trunk of TDA,as well as contrast-to-noise ratio of axillary artery increased(all P＜0.01).Conclusion Performing CTA using 50 keV single energy imaging combined with 80%ASIR-V reconstruction could balance image contrast and noise better,hence improving visualization of TDA and its branches.

Objective To explore the application value of deep learning image reconstruction(DLIR)algorithm in low-dose deep inferior epigastric artery(DIEA)computed tomography angiography(CTA).Methods A total of 59 patients undergoing DIEA CTA were prospectively selected and randomly divided into two groups:group A(29 cases)and group B(30 cases).Group A was the conventional radiation dose group(tube voltage 120 kVp),the tube current was dose modulation 3,and the iterative reconstruction algo-rithm was Karl 5.Group B was the low radiation dose group(tube voltage 120 kVp),the tube current was dose modulation 2,with DLIR reconstruction algorithm,and four levels of DLIR(1-4)were reconstructed and labeled as groups B1 to B4.The mean tube current,vol-ume CT dose index(CTDIvol),and dose length product(DLP)of group A and group B were recorded,and the effective dose(ED)was calculated.The CT and standard deviation(SD)values of the external iliac artery and psoas major muscle were measured on axial images of each group,and signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)were calculated.Two observers using double-blind method independently evaluated the DIEA on volume rendering(VR)and maximum intensity projection(MIP)images of each group using a 3-point scale,and a 5-point scale was used to evaluate the overall image quality on axial images.Results Compared with group A,the mean tube current and ED in group B were decreased by 39.33％and 44.09％,respectively(P＜0.05).With the increasing of DLIR level from groups B1 to B4,the SD value of the image gradually decreased,while SNR and CNR gradually increased(P＜0.05).The CNR in groups B3 and B4 was higher than that in group A(P＜0.05).The subjective scores of the two observers were consistent(Kappa value 0.779-0.889,P＜0.05),and there was no statistical significance between group A and group B in the perforating vessels from the DIEA,intramuscular course,and the point of emergence(P＞0.05).With the increase in DLIR level,the subjective score of the overall image quality from group B1 to group B4 showed a trend of first increasing and then decreasing,and the score of group B3 was the highest(4.50±0.51)points,which had no statistical significance compared with group A(4.45±0.51)points(P＞0.05).Conclusion DLIR can effectively reduce the radiation dose of the DIEA CT A scan and ensure the image quality,among which DLIR 3 is the recommended best reconstruction grade.

Objective To explore the application value of 1 024×1 024 reconstruction matrix combined with iterative reconstruc-tion algorithm(Karl)in deep inferior epigastric artery(DIEA)computed tomography angiography(CTA).Methods A total of 40 patients who underwent DIEA CTA were prospectively selected and the original data were reconstructed by grouping.Group A was reconstructed using a conventional 512×512 matrix combined with Karl 5 grade.Group B was reconstructed using 1 024×1 024 recon-struction matrix combined with Karl 5,7,and 9 grades,respectively,and 3 subgroups B1-B3 were obtained.The CT and standard devia-tion(SD)values of the external iliac artery and psoas major muscle were measured on axial images,and signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)were calculated.A 3-point scale was used to evaluate the perforating vessels from the DIEA,intramuscular course,point of emergence,superficial inferior epigastric artery(SIEA)and superficial inferior epigastric vein(SIEV)on volume ren-dering(VR)and maximum intensity projection(MIP)images by two observers,and a 5-point scale was used to evaluate the overall image quality on axial images.Results With the increase of Karl grade in groups B1 to B3,the SD value of the external iliac artery decreased gradually(P＜0.05),while SNR and CNR increased gradually(P＜0.05).The SD values of the external iliac artery in group B2 and group B3 were lower than those in group A(P＜0.05),and SNR and CNR were higher than those in group A(P＜0.05).There was a good consistency in the subjective evaluation between the two observers(Kappa values=0.773-0.872,P＜0.05).The perforating vessels from the DIEA,intramuscular course,point of emergence,SIEA and SIEV display and overall image quality subjective scores of group B2 and group B3 were better than those of group A(P＜0.05),and the scores of group B2 showed the greatest improvement.Conclusion The 1 024 × 1 024 reconstruction matrix combined with the Karl 7 reconstruction algorithm can optimize the image quality and improve the display of the DIEA and perforator microvessels.

Objective To investigate the clinical application value of posterior adaptive statistical iterative reconstruction-Veo(ASIR-V)algorithm combined with full-field organ dose modulation(ODM)technique in low-dose computed tomography urography(CTU).Methods Ninety patients who underwent urological contrast-enhanced and CTU examination were prospectively selected and divided into conventional dose group(group A,NI=11,posterior ASIR-V of 60％),low-dose group(group B,NI=15,posterior ASIR-V of 60％-100％with 10％interval,denoted as B1-B5 groups);full-field ODM low-dose group(group C,NI=15,posterior ASIR-V of 60％-100％with 10％interval,denoted as C1-C5 groups)according to the noise index(NI).The volume rendering(VR)and maximum intensity projection(MIP)images were reconstructed.The CT values and standard deviation(SD)values of the renal cortex and para-spinal muscles were measured,and the signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)were cal-culated.The CT values of the renal pelvis,ureter,and bladder were measured,and the SNR and CNR were calculated with the para-spinal muscles as background.The subjective score was performed on the two-dimensional and three-dimensional images to evaluate the ability of CTU to display lesions.The volume CT dose index(CTDIvol),dose length product(DLP),and effective dose(ED)of the three groups were compared.Results The bladder SNR and CNR of groups B1,C1,and C2 were lower than those of group A(P＜0.05).There was no statistically significant difference in the SNR and CNR of each tissue between groups B2,C3 and group A(P＞0.05).The SNR and CNR of each tissue in groups B4,B5,and C5 were higher than those in group A(P＜0.05).The display rate of lesions in urinary system in groups B2 and C3 could reach 100％.There was no statistically significant difference in the axial image scores between groups B2,C3 and group A(P＞0.05),while the VR and MIP image scores in each group were comparable to those in group A(P＞0.05).The CTDIvol of groups A,B and C were(6.08±2.11)mGy,(3.15±1.15)mGy,and(2.9±0.92)mGy,respectively.Conclusion CTU using the full-field ODM technique combined with posterior 80％ASIR-V can reduce the CTDIvol by 52.30％,and further reduce by 7.93％compared with group B,which is effective to reduce radiation to the gonads.
