ObjectiveTo investigate the effects of Yueju Wan on the 5-hydroxytryptamine （5-HT） signaling pathway in rats with functional dyspepsia （FD） and to explore its therapeutic mechanism in the treatment of FD. MethodsSixty Sprague-Dawley （SD） rats were randomly divided into a normal group， model group， mosapride group （1.575 mg·kg^-1）， and Yueju Wan low-， medium-， and high-dose groups （0.735， 1.47， and 2.94 g·kg^-1， respectively）. The FD rat model was established using GUO's tail-clamping stimulation combined with irregular feeding. After 14 days of modeling， rats were administered the corresponding drugs by gavage for 28 days. After treatment， gastric emptying rate and small intestinal propulsion rate were measured. Serum levels of 5-HT， tryptophan hydroxylase （TPH）， and substance P （SP） were detected by enzyme-linked immunosorbent assay （ELISA）， and acetylcholine （ACh） levels were determined by chemical methods. Histopathological changes in the gastric antrum were observed using hematoxylin-eosin （HE） staining. Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to assess the mRNA and protein expression levels of 5-hydroxytryptamine 4 receptor （5-HT4R）， SP， and acetylcholinesterase （AChE） in colon tissue， as well as 5-hydroxytryptamine 3 receptor （5-HT3R）， SP， and AChE in hypothalamic tissue. Immunohistochemistry （IHC） was used to examine the expression of 5-HT and 5-HT4R in the colon and 5-HT and 5-HT3R in the hypothalamus. ResultsCompared with the normal group， the gastric emptying rate and small intestinal propulsion rate in the model group were significantly decreased （P<0.01）. Serum levels of 5-HT， SP， ACh， and TPH were significantly reduced （P<0.01）. Histopathological examination revealed irregular arrangement of glands in the gastric antrum， slight mucosal atrophy， and mild inflammatory cell infiltration. The mRNA and protein expression levels of 5-HT4R， SP， and AChE in colon tissue， as well as 5-HT3R， SP， and AChE in hypothalamic tissue， were significantly decreased （P<0.01）， and 5-HT protein expression in both the colon and hypothalamus was also significantly reduced （P<0.01）. Compared with the model group， all Yueju Wan groups showed significantly increased gastric emptying rate and small intestinal propulsion rate （P<0.01）. The glands in the gastric antrum were more regularly arranged， with no inflammatory cell infiltration observed. Serum levels of 5-HT， SP， ACh， and TPH were significantly increased （P<0.01）. The mRNA and protein expression levels of 5-HT4R， SP， and AChE in colon tissue and 5-HT3R， SP， and AChE in hypothalamic tissue were significantly upregulated （P<0.05， P<0.01）， and 5-HT protein expression in both the colon and hypothalamus was significantly increased （P<0.01）. ConclusionYueju Wan has preventive and therapeutic effects on FD， and its mechanism may be related to regulation of the 5-HT signaling pathway， promotion of brain-gut peptide secretion， and enhancement of gastric motility.

Diabetic cardiomyopathy （DCM） is one of the most common complications of diabetes mellitus and is a major threat to global health. As a key mechanism in the occurrence and progression of DCM， the inflammatory response persists throughout the entire course of the DCM. The Gaozhuo theory suggests that the basic pathogenesis of inflammatory injury in DCM is the Qi deficiency of spleen and kidney and Gaozhuo invasion， and divides the pathological process into three phases： Gaozhuo invasion， turbid heat damage to the channels， and turbid blood stasis and heat junction. Among them， the Qi deficiency of spleen and kidney and the endogenous formation of Gaozhuo represent the process of inflammatory factor formation induced by glucose metabolism disorders. Turbid heat damage to the channels refers to the process of myocardial inflammatory injury mediated by inflammatory factors， and turbid blood stasis and heat junction are the process of myocardial injury developing toward myocardial fibrosis and ventricular remodeling. As the disease continues to progress， it eventually develops into a depletion of the heart Yang， leading to the ultimate regression of heart failure. According to the theory of Gaozhuo， traditional Chinese medicine （TCM） should regulate inflammatory injury in DCM by strengthening the spleen and tonifying the kidney to address the root cause， and resolving dampness and lowering turbidity to treat the symptoms. If the turbidity has been stored for a long time and turns into heat， strengthening the spleen and tonifying the kidney， and clearing heat and resolving turbidity should be the therapy. If the turbidity， stasis， and heat are knotted in the heart and collaterals， strengthening the spleen and tonifying the kidney， and resolving stasis and lowering turbidity should be the therapy. TCM compounds and monomers can regulate the inflammatory response in DCM. TCM compounds can be divided into the categories for benefiting Qi to resolve turbidity， benefiting Qi and clearing heat to resolve turbidity， and benefiting Qi and activating blood to reduce turbidity. The compounds can inhibit upstream signals of inflammation and expression of inflammatory factors， improve the inflammatory damage to myocardium and blood vessels， myocardial fibrosis， and cardiac systole and diastole， and thus slow down the onset and progression of DCM.

AIM: To explore the effect of adiponectin(ADPN)on angiogenesis of human retinal microvascular endothelial cells(hRMECs)in high glucose(HG)environment and role of NOD-like receptor family pyrin domain containing 3(NLRP3)inflammasome.METHODS: The hRMECs were divided into six groups, including control group(without treatment), HG group: incubated with D-glucose, ADPN group: pretreatment with ADPN and then incubated with D-glucose, CY-09 group: pretreatment with CY-09(an NLRP3 inhibitor)and then incubated with D-glucose, Nigericin group: pretreatment with nigericin(an NLRP3 activator)and then incubated with D-glucose, Nigericin+ADPN group: pretreatment with nigericin and ADPN and then incubated with D-glucose. NLRP3 level was detected using Western blot analysis. hRMECs migration was measured using scratch wound healing assay. The tube formation of hRMECs was detected using Matrigel.RESULTS: The NLRP3 expression in hRMECs cultured in an HG environment was significantly increased(P<0.01), while ADPN and CY-09 reduced the elevated NLRP3(both P<0.05 vs HG group). Nigericin significantly increased NLRP3 levels(P<0.01 vs control group)which was reversed by ADPN(P=0.032 vs Nigericin group). hRMECs migration ability(P<0.001), and total master segments length and number of meshes increased in HG group(P<0.001)while decreased in ADPN and CY-09 groups(all P<0.01 vs HG group). The hRMECs migration ability and tube formation(total master segments length and number of meshes)in HG environment were significantly increased by nigericin(P=0.003), while ADPN inversed the change. CONCLUSION: ADPN alleviates the migration and angiogenesis of hRMECs under HG conditions.

Objective: To understand the current status of short video addiction among vocational nursing students in higher vocational colleges (hereinafter referred to as "nursing students") and its related factors, so as to provide a reference for formulating online education programs in colleges. Methods: From March to May 2025, a stratified random sample of 2 223 nursing students from four vocational colleges in Henan Province was selected. Short Video Addiction Scale for College Students, Short form Egna Minnen av Barndoms Uppfostran for Chinese, Peer Rejection Scale, and University of California at Los Angels Loneliness Scale were used for investigation. Chi square test and multivariate Logistic regression analysis were used to explore the related factors of short video addiction among nursing students. Results: The detection rate of short video addiction of higher vocational nursing students was 26.95%, and the scores for avoidance, loss of control, inefficiency and withdrawal were (8.05±2.97) (10.24±3.09) (4.99±1.88) and (11.97±4.10), respectively. Multivariate Logistic regression analysis showed that sophomore year 2 ( OR=1.83, 95%CI =1.39-2.40), higher maternal education level (secondary school/vocational college: OR =1.34, 95% CI =1.06-1.68; college/undergraduate: OR =1.38, 95% CI =1.05-1.82), paternal overprotection ( OR=1.59, 95%CI =1.27-2.00), high peer rejection ( OR=1.40, 95%CI =1.19-1.66), and strong loneliness ( OR=1.57, 95%CI =1.07-2.28) were associated with a higher risk of short video addiction among nursing students (all P <0.05). Paternal affectionate and warm rearing style ( OR=0.82, 95%CI = 0.71- 0.95) was associated with a lower risk of short video addiction ( P <0.05). Conclusions The detection rate of short video addiction among nursing students is relatively high. Short video addiction is related to the nursing students grade, maternal education level, paternal overprotection and affectionate rearing style, peer rejection, and loneliness.

ObjectiveTo investigate the effect of Danggui Shaoyaosan on ferroptosis in the rat model of non-alcoholic fatty liver disease （NAFLD） and explore the underlying mechanism based on the nuclear factor E₂-related factor 2 （Nrf2）/solute carrier family 7 member 11 （SLC7A11）/glutathione peroxidase 4 （GPX4） signaling pathway. MethodsThe sixty SD rats were randomly grouped as follows： control， model， Yishanfu （0.144 g·kg^-1）， and low-， medium-， and high-dose （2.44， 4.88， and 9.76 g·kg^-1， respectively） Danggui Shaoyaosan. A high-fat diet was used to establish the rat model of NAFLD. After 12 weeks of modeling， rats were treated with corresponding agents for 4 weeks. Then， the body weight and liver weight were measured， and the liver index was calculated. At the same time， serum and liver samples were collected. The levels or activities of total cholesterol （TC）， triglycerides （TG）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， and Fe²⁺ in the serum and TC， TG， free fatty acids （FFA）， malondialdehyde （MDA）， superoxide dismutase （SOD）， glutathione peroxidase （GPX）， and Fe²⁺ in the liver were measured. Hematoxylin-eosin staining and oil red O staining were employed to observe the pathological changes in the liver. Immunofluorescence was used to assess the reactive oxygen species （ROS） content in the liver. Mitochondrial morphology was observed by transmission electron microscopy. The protein levels of Nrf2， SLC7A11， GPX4， transferrin receptor 1 （TFR1）， and divalent metal transporter 1 （DMT1） in the liver were determined by Western blot. ResultsCompared with the control group， the model group showed increases in the body weight， liver weight， liver index， levels or activities of TC， TG， ALT， AST， and Fe²⁺ in the serum， levels of TC， TG， FFA， MDA， Fe²⁺， and ROS in the liver， and protein levels of TFR1 and DMT1 in the liver （P<0.01）， and decreases in the activities of SOD， GPX and the protein levels of Nrf2， SLC7A11， and GPX4 in the liver （P<0.05， P<0.01）. Meanwhile， the liver tissue in the model group presented steatosis， iron deposition， mitochondrial shrinkage， and blurred or swollen mitochondrial cristae. Compared with the model group， all doses of Danggui Shaoyaosan reduced the body weight， liver weight， liver index， levels or activities of TC， TG， ALT， AST， and Fe²⁺ in the serum， levels of TC， TG， FFA， MDA， Fe²⁺， and ROS in the liver， and protein levels of TFR1 and DMT1 in the liver （P<0.01）， while increasing the activities of SOD and GPX and the protein levels of Nrf2， SLC7A11， and GPX4 in the liver （P<0.01）. Furthermore， Danggui Shaoyaosan alleviated steatosis， iron deposition， and mitochondrial damage in the liver. ConclusionDanggui Shaoyaosan may inhibit lipid peroxidation and ferroptosis by activating the Nrf2/SLC7A11/GPX4 signaling pathway to treat NAFLD.

Objective To investigate the relationship between cerebrospinal fluid(CSF)colony stimulating factor 1 receptor(CSF1R)and CSF biomarkers of Alzheimer disease(AD),and to analyze whether CSF1R is associated with mild cognitive impairment patients'cognition.Methods Data from non-demented adults were collected from the Alzheimer Disease Neuroimaging Initiative database,and participants were divided into four groups(A-/TN-,A+/TN-,A+/TN+and A-/TN+),according to the NIA-AA criteria,and the dynamic changes of CSF1R in CSF at different pathological stages of AD were tracked.Multiple linear regression models were used to analyze the relationship between CSF1R and AD biomarkers and cognition,and mediation models were used to investigate the potential association between CSF1R and AD pathology.Results A total of 451 non-demented adults were enrolled in this study,and we found that CSF CSF1R levels were increased in the A-/TN+group(P<0.05)and the A+/TN+group(P<0.05)compared with the A+/TN-group.CSF CSF1R levels were significantly and positively correlated with CSF tau protein(P<0.001)and phosphorylated tau protein(P<0.001)levels but not with amyloid β-protein(P=0.123),and similar results were obtained in the cognitively normal and mild cognitive impairment groups.In the mild cognitive impairment group,higher CSF CSF1R levels were associated with lower cognitive(P<0.05)levels.Furthermore,the relationship between CSF1R and AD pathology was mediated in part by soluble triggering receptor expressed on myeloid cells 2(sTREM2)(percentage:19.3%to 31.4%).Conclusions This study is the first study to discover the association of CSFIR with AD biomarkers and cognition,and CSF1R may influence AD pathology through soluble TREM2(sTREM2).

Objective:To design and develop a battlefield first-aid simulated training system, to evaluate the application effect of the system through a quasi-experimental controlled trial, and to provide training means to support the enhancement of Chinese army's first-line treatment capability.Methods:A battlefield first-aid simulated training system was designed and developed with the guidance of the theory of "experiential learning cycle". From March to June 2023, 108 health sergeants who participated in non-academic education training from a military medical university were recruited to a quasi-experimental controlled trial and randomly divided into a control group and an experimental group, with 54 sergeants each. The control group was trained using traditional face-to-face simulation training, and the experimental group was trained using the Battlefield First-aid Simulated Training System. The differences in effects of computer simulation training and traditional face-to-face simulation training were compared, with the primary evaluation indices being the first-aid knowledge level and inferential capability of rescue on the battlefield, and the secondary evaluation indices being the self-perception and training satisfaction. The SPSS 26.0 software was used for conducting the t test, chi-square test or Fisher's exact probability test, and non-parametric test. Results:All 108 subjects completed the training and had an improvement in the knowledge level, self-perception, and inferential capability of rescue after the training ( P<0.001). The difference in the degree of improvement in the knowledge level [(19.93±8.98) vs. (16.55±10.10)] and self-perception [10.50 (7.00, 13.25) vs. 10.00 (7.00, 12.50)] was not statistically significant between the experimental group and the control group ( P>0.05), but the degree of improvement in the inferential capability of rescue of the experimental group [6.00 (5.00, 9.25)] was significantly lower than that of the control group [8.00 (7.00, 11.00)] ( P<0.05). There was no significant difference in the training satisfaction scores between the two groups ( P>0.05). Conclusions:The system has a similar training effect to traditional face-to-face simulation training, but shows a slight deficiency in the improvement in the inferential capability of rescue. It serves as a recommended training resource and format from battlefield first-aid theory learning to practical application. The system still needs to be optimized and improved in the aspects of functionality, simulation, and intellectualization in the future.

Objective:To identify the risk factors associated with the development of post-Nuss proce-dure scoliosis in pectus excavatum patients and to establish a relevant predictive model.Methods:A retro-spective review was conducted on pectus excavatum patients who underwent Nuss procedure in Depart-ment of Thoracic Surgery at Beijing Jishuitan Hospital between January 2018 and February 2023.We gathered the patient demographic information(including age,sex,height,weight,and body mass in-dex)and diagnostic imaging results(echocardiogram,chest CT scan,full-spine radiography,and PA/lateral chest X-rays),and measurements of Haller index,asymmetry index,sternal torsion angle(STA)index,and Cobb angle changes.The risk of post-Nuss procedure scoliosis was assessed.Cox regression analysis was performed to identify independent risk factors for scoliosis development in the pectus excava-tum patients.Based on the results of the Cox regression analysis,a risk prediction model was estab-lished,and its specific predictive performance was assessed through internal cross-validation.Results:A total of 59 pectus excavatum patients who underwent Nuss procedure were included after applying inclu-sion and exclusion criteria.The median follow-up duration was 6.84 months,and the follow-up results showed significant improvements in Haller index,STA index,and asymmetry index postoperatively.Twelve patients developed scoliosis 3 months after Nuss procedure,while 47 patients did not,the inci-dence of scoliosis was 20.3％.Cox regression analysis identified preoperative pulmonary artery hyperten-sion and preoperative asymmetry index as independent risk factors for post-Nuss procedure scoliosis.A predictive model was constructed based on single-factor Cox regression analysis results,incorporating age,height,weight,body mass index,preoperative pulmonary artery hypertension,preoperative Haller index,STA index,asymmetry index,and Cobb angle.The receiver operating characteristic(ROC)curve was plotted,and the area under the curve(AUC)for the overall predictive model was calculated to be 0.995.A calibration curve demonstrated good alignment between predicted values and actual values.Conclusion:Nuss procedure achieved favorable clinical outcomes.However,postoperative scoliosis emerged as a significant complication with a high incidence rate.Pulmonary artery hypertension and asymmetry index were independent predictors of post-Nuss procedure scoliosis.The predictive model developed in this study demonstrated robust performance in estimating the risk of postoperative scoliosis.

The widespread implementation of low-dose computed tomography screening has led to a substantial rise in the detection of pulmonary nodules,with multiple pulmonary nodules(MPNs)now representing a common clinical presentation.Conventional diagnostic and therapeutic paradigms,characterized by sequential,multi-site processes,are often limited by inefficiency,safety concerns,and suboptimal patient outcomes.In contemporary thoracic surgery,a transformative"one-stop"precision management strategy has emerged within hybrid operating theaters.This integrated approach synergizes intraoperative imaging,advanced navigation,and surgical intervention to address these limitations.Cone-beam CT plays a pivotal role in this model by leveraging its maneuverability,low radiation,and high spatial resolution to greatly facilitate the development of precise diagnosis and treatment for MPNs.
