ObjectiveTaking the cuproptosis/oxidative stress pathway as the entry point， this study investigated the effect and mechanism of Liangyi Paste on hepatic lipid deposition in naturally aged mice fed with a high-fat diet. MethodsAfter adaptive feeding， 80 ten-week-old male C57BL/6 mice were used. Thirty of them were randomly divided into three groups （10 mice per group）： The 12-month-old control group （12MCON）， the 15-month-old control group （15MCON）， and the 15-month-old group with a high-fat diet （15MHFD）. The 12MCON and 15MCON groups were continuously fed a standard diet， while the 15MHFD group started receiving a high-fat diet at 12 months of age. Tissue samples were collected at the corresponding time points for each group. The remaining 50 mice were randomly divided into five groups （10 mice per group）： the 20-month-old control group （20MCON）， the model group， and the low-， medium-， and high-dose Liangyi Paste groups （2.91 ， 5.82 ， 11.64 g·kg^-1·d^-1， respectively）. The 20MCON group was continuously fed a standard diet， while the other groups started receiving a high-fat diet at 15 months of age. At 18 months of age， the Liangyi Paste groups were administered the corresponding doses of Liangyi Paste by gavage， while the 20MCON and model groups were given an equal volume of saline by gavage. After 8 weeks of continuous gavage （when the mice reached 20 months of age）， tissue samples were collected. Hepatic TG levels were measured using assay kits； liver histology and lipid deposition were observed via hematoxylin-eosin （HE） and oil red O staining； reactive oxygen species （ROS） were detected by enzyme-linked immunosorbent assay （ELISA）； Cu²⁺， superoxide dismutase （SOD）， and malondialdehyde （MDA） levels were measured by colorimetry； mRNA and protein expression of genes related to cuproptosis and oxidative stress pathways were analyzed by Real-time polymerase chain reaction（Real-time PCR） and Wes automated protein expression system. ResultsCompared with 12MCON， the 15MCON group showed significantly increased hepatic TG， Cu²⁺， ROS， and MDA levels （P<0.01）， decreased SOD （P<0.01）， hepatocyte swelling， and disordered arrangement. The mRNA and protein levels of ferredoxin 1 （FDX1）， dihydrolipoamide S-acetyltransferase （DLAT）， heat shock protein 70 （HSP70）， dihydrolipoamide dehydrogenase （DLD）， pyruvate dehydrogenase E1 subunit-β （PDHB）， nuclear factor erythroid 2-related factor 2 （Nrf2）， and peroxisome proliferator-activated receptor γ （PPARγ） were significantly elevated （P<0.05， P<0.01）. Compared with 15MCON group， the 15MHFD and 20MCON groups exhibited further increases in TG， Cu²⁺， ROS， and MDA （P<0.01）， reduced SOD （P<0.01）， and aggravated hepatocyte swelling and disorder. There were increased lipid droplets with mild vacuolization in the 15MHFD group， and no significant lipid deposition was observed in the 20MCON group. FDX1， DLAT， HSP70， DLD， PDHB， Nrf2， and PPARγ mRNA and protein levels were significantly increased （P<0.05， P<0.01）. Compared with 20MCON group， the model group demonstrated markedly elevated TG， Cu²⁺， ROS， and MDA （P<0.01）， reduced SOD （P<0.01）， severe hepatic steatosis， and upregulated expression of FDX1， DLAT， HSP70， DLD， PDHB， Nrf2， and PPARγ mRNA and proteins （P<0.05， P<0.01）. All abnormalities were significantly reversed after Liangyi Paste treatment. ConclusionLiangyi paste can ameliorate hepatic lipid deposition in naturally aged mice with a high-fat diet by modulating the cuproptosis/oxidative stress pathway.

OBJECTIVE: To explore the prenatal and postnatal phenotypes of 22q11.2 microdeletion syndrome (22q11.2DS) and enhance clinical understanding of this condition. METHODS: Data were collected from 86 fetuses diagnosed with 22q11.2DS at four prenatal diagnostic centers across China between January 2014 and August 2025. Prenatal imaging findings, pregnancy outcomes, and postnatal conditions were analyzed. RESULTS: Among the 86 fetuses, complete ultrasound data were available for 65 cases. Cardiovascular abnormalities were observed in 42 cases, thymic hypoplasia or aplasia in 7 cases, urinary system anomalies in 6 cases, nuchal translucency (NT) thickening in 7 cases, butterfly vertebrae, clubfoot, omphalocele and diaphragmatic hernia in 1 case each, cleft lip and palate in 2 cases, and ultrasound soft markers in 13 cases. The parents of 9 fetuses opted to continue with the pregnancy. Among these, 6 showed no significant ultrasound abnormalities and no related phenotypes postnatally, while the remaining 3 exhibited ultrasound anomalies with postnatal manifestations including developmental delay, immunodeficiency, and cardiac defects. CONCLUSION Fetuses with 22q11.2DS may exhibit various ultrasound abnormalities in multiple systems before and after birth. In addition to cardiovascular anomalies, they may also present with thymic hypoplasia or aplasia, thickened NT, and urinary abnormalities. Fetuses with thickened NT or thymic anomalies should be closely monitored, and thymic assessment should be included in routine prenatal imaging evaluations. For fetuses with 22q11.2DS who show no ultrasound abnormalities, the risk of developing severe phenotypes after birth is relatively low, but occult palate clefts and psychiatric disorders cannot be ruled out. Due to limitations in sample size and follow-up duration, above conclusions require further validation through large-scale prospective studies.

Objective: To investigate the epidemiological and spatio-temporal characteristics of influenza in Jiaxing City, Zhejiang Province, so as to provide insights into perfecting the prevention and control strategies of influenza. Methods: Data of influenza in Jiaxing City from 2019 to 2023 were collected from the Chinese Disease Prevention and Control Information System. Population data of the same period were collected from the Zhejiang Health Information Network Reporting System. The epidemiological characteristics of influenza were analyzed using descriptive analysis. Vector map information was collected from the Open Street Map, and the spatio-temporal clustering characteristics of influenza were analyzed using spatial autocorrelation and spatio-temporal scanning. Results: A total of 181 501 cases of influenza were reported in Jiaxing City from 2019 to 2023, with an average annual reported incidence of 653.93/105. The majority of cases were aged 5 to <15 years (59 785 cases, 32.94%). The majority of the occupations were students (78 239 cases, 43.11%) and pre-school children (33 715 cases, 18.58%). The county (city, district) with the highest reported incidence was Haining City (1 451.70/105), and the town (street) with the highest reported incidence was Chang'an Town (1 932.78/105). Spatial autocorrelation analysis showed that the incidence of influenza in Jiaxing City from 2019 to 2023 had positive spatial correlations (all Moran's I>0, all P<0.05), with a high-high clustering in the southern region. Spatio-temporal scanning analysis showed that there was a spatio-temporal clustering of influenza in Jiaxing City from 2019 to 2023, with the southern region being the primary-type clustering area and the period between November and January of the following year being the clustering time. Conclusion There was a significant spatio-temporal clustering of influenza in Jiaxing City from 2019 to 2023, with winter being the peak season and the southern region being the primary area.

Objective To explore the traditional Chinese medicine(TCM)syndrome characteristics of patients with Chikungunya hemorrhagic fever and to provide empirical data to support the application of TCM in diagnosing and treating Chikungunya hemorrhagic fever.Methods A cross-sectional survey was conducted to collect clinical data(sex,age,days since onset,and comorbidity underlying disease conditions)and TCM with four-examination information(symptoms,tongue manifestations,and pulse manifestations)from 255 patients with Chikungunya hemorrhagic fever who visited Lecong Hospital of Shunde,Foshan,the Third People's Hospital of Shunde District of Foshan,Shunde Hospital of Southern Medical University Affiliated Chencun Hospital between July 23 and July 29,2025.Factor and cluster analyses were used to summarize TCM syndrome characteristics and analyze core pathogenesis in conjunction with clinical features.Results Among the 255 patients with Chikungunya hemorrhagic fever,131 were male and 124 were female,with a age of(49.05±17.93)years and a disease duration of(3.26±1.78)days.Among the four types of examination information in TCM,35 items exhibited a frequency exceeding 10%.The most prevalent symptoms were arthralgia(180 patients,70.59%),exanthem(153 patients,60.00%),fatigue(99 patients,38.82%),anhidrosis(98 patients,38.43%),pruritus(96 patients,37.65%),and fever(92 patients,36.08%).Tongue and pulse manifestations were primarily white fur(155 patients,60.78%),pink tongue(111 patients,43.53%),slippery pulse(143 patients,56.08%),and greasy fur(134 patients,52.53%).Patients with disease onset≤3 d had a higher incidence of arthralgia,fatigue,fever,aversion to cold,generalized muscle pain,aversion to wind,insomnia,headache,sweating,low-grade fever,poor appetite,loose stool,hyperhidrosis,and red tongue than those with disease onset≥4 d(P<0.05).Patients with disease onset≥4 d had a higher incidence of pink tongue and thick fur than those with disease onset≤3 d(P<0.05).The syndrome elements in patients with Chikungunya hemorrhagic fever predominantly manifested on the defensive exterior,with involvement of the sinew-bone joints,skin-muscle,and spleen.Pathogenic factors were primarily characterized by external winds,dampness,and heat.Factor and cluster analysis result indicated three TCM pathogenesis progression patterns:imbalance of the defensive exterior with wind-dampness conflict and heat transformation;dampness-heat flowing into muscles and meridians causing joint obstruction and qi blood stasis;and dampness-heat congelation resulting in qi mechanism obstruction,consumption of body fluids,and infiltration of the skin.Conclusion Patients with Chikungunya hemorrhagic fever primarily present with fever,joint pain,and rashes.In TCM,this condition falls under the category of"dampness-warmth"syndrome.Its etiology is attributed to pathogens,with transmission occurring through mosquito bites.The core pathogenesis of TCM is the invasion of the defensive exterior and dampness-toxic heat accumulation.The therapeutic principles focus on clearing heat pathogens,resolving dampness pathogens,dispersing wind pathogens,and promoting the resolution of rashes.

Photodynamic therapy(PDT)is a precise targeted therapy that selectively treats certain benign diseases and malignant tumors by combining therapeutic light sources,photosensitizers,and oxygen molecules.The wavelength range of the light source,as a key factor in inducing PDT,has a decisive impact on the triggering and therapeutic effect of the treatment.However,there is a lack of relevant reviews on the selection of light sources for photodynamic therapy.This article reviews the PDT-related applications of commonly used light sources with different wavelength ranges of excitation,such as visible light,near-infrared,and X-ray,including the excitation characteristics of this band of light,as well as the multi-therapy combination and multi-range breakthroughs of PDT cancer treatment under the excitation of this band of light.The aim is to provide feasible directions for the development of photodynamic therapy bands and subsequent applications.

Objective Compare the depression phenotypes of a breast cancer tumor-bearing mouse model constructed using two different method and a mouse model of breast cancer depression with clinical manifestations,as well as assess their suitability for basic research.Methods We constructed a tumor model with 4T1 breast cancer cells alone(4T1 group)and a tumor-depression composite model given chronic unpredictable mild(CUMS)(4T1+CUMS group).The experimental period was 42 d,and the body mass,tumor volume,and survival time of the mice were monitored throughout the whole process.Two depressive behavioral tests(of sucrose preference test,open field test,tail suspension test,and elevated plus maze)were performed on the 15th and 29th days,respectively.Hematoxylin-eosin(HE)staining was used to observe the pathological changes of hippocampal neurons in brain tissue sections.Results(1)Body mass:The body mass of the 4T1 group and 4T1+CUMS group began to decrease from 29 d,and the body mass of the 4T1+CUMS group was significantly lower than that of the 4T1 group and Control group at the end of the experiment(P<0.001).(2)Tumor volume:There was no significant difference in the growth rate of tumors between the two model groups throughout the experiment(P>0.05).(3)Survival time:The survival rates of the 4T1 group and 4T1+CUMS group were 100％and 60％,and the first death of mice in the 4T1+CUMS group was on the 36th day.(4)Behavior test of depression:There was no significant difference between the three groups in the first depressive behavior tests(P>0.05),and the two groups showed obvious depressive phenotypes in the second behavioral tests.The sucrose preference index and activity distance in the central area were significantly decreased in the two model groups(P<0.001),and the immobility time was significantly increased(P<0.001).(5)Pathological section of brain tissue:On pathological examination of brain tissue,we observed a reduced number of neuronal cells in the hippocampus of the 4T1 group and 4T1+CUMS group,their morphology was irregular,the arrangement between the cells was disordered and the gap was unclear,and some nucleoli were blurred.Conclusions Although the tumor-only method and the tumor with compound stress stimulation method can both be used to prepare breast cancer depression models,the tumor-only modeling method is simpler and the mortality rate after successful modeling is higher.The long window of time is convenient for subsequent drug administration and detection,and the causes of the depression phenotype are more in line with the clinical causes and manifestations.Therefore,the 4T1 model can provide a reference model for future animal experiments on breast cancer tumor-related depression.

AIM:This study aimed to utilize network pharmacology and an anxiety rat model to investigate the intervention targets and underlying mechanisms of Baixiangdan capsule(BXD)in the treatment of anxiety-like behavior.METHODS:We screened the action targets of BXD on the anxiety model using network pharmacology,followed by Gene Ontology(GO)enrichment and the Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis of the identified targets.Additionally,we evaluated the effects of BXD on rat anxiety behaviors induced by foot shock,with measurement of serum level of c-Jun N-terminal kinase inhibitor(JIK),and the protein levels of c-Jun N-terminal kinase(JNK),phos-phorylated JNK(p-JNK)and JIK in the left hippocampus and hypothalamus.RESULTS:A total of 97 targets,including the dopamine D1/D3 receptors,were identified as intersection targets.GO enrichment analysis indicated that target pro-teins were significantly involved in molecular functions such as catecholamine binding,receptor activation,and signal transduction.KEGG pathway analysis revealed that neural receptor-ligand pathways,including dopaminergic synapses(15%)and neuroactive ligand-receptor interaction(18%),were notably represented.In behavioral experiments,BXD and diazepam treatments significantly reduced total path in the open-field test(P＜0.01),while the number of entries into the central region increased(P＜0.05).Additionally,the percentage of entry times of the open arm and the percentage of time spent in the open arm were also increased(P＜0.01).Furthermore,BXD treatment led to decreased ratio of p-JNK/JNK and increased level of JIK(P＜0.05).CONCLUSION:The traditional Chinese medicine BXD demonstrates a promising efficacy in alleviating anxiety-like behaviors in model rats.It operates through a multi-component,multi-target,and multi-pathway approach,primarily by modulating the JIK/JNK signaling pathway.

Objective:To investigate the association between the triglyceride-glucose(TyG)index and the incidence and mortality of cardiovascular disease(CVD)in a large population-based cohort.Methods:Participants aged 40-79 years without a history of CVD at baseline were drawn from the CHi-nese Electronic health Records Research in Yinzhou(CHERRY)study between January 1,2010,and May 31,2020.The TyG index was calculated using baseline triglyceride and fasting blood glucose.Cox proportional hazards models were used to assess the association between the TyG index and the composite outcome of CVD(incidence and mortality),adjusting for age,gender,education,region,smoking sta-tus,body mass index,systolic blood pressure,and total cholesterol.Hazard ratios(HR)and 95％confi-dence intervals(CI)were calculated.Nonlinear associations between the TyG index and CVD were fur-ther evaluated using restricted cubic splines,and subgroup analyses by gender and age were conducted to explore potential differences.Results:A total of 226 406 individuals were included,with a mean age of(55.0±9.7)years at baseline,46.8％of whom were men,and a median TyG index of 8.68.Over a median follow-up of 7.99 years,9 815(4.34％)participants experienced CVD incidence or mortality.After adjusting for age,gender,education,region,smoking status,body mass index,systolic blood pressure and total cholesterol,the risk of CVD increased with higher TyG index levels(P＜0.001).The risk in the highest TyG quartile(TyG＞9.10)was 42％higher than in the lowest quartile(TyG ≤8.32)(HR=1.42,95％CI:1.34-1.51).Individuals under 60 years had a higher HR for CVD compared with those aged 60 years and above(HR:1.71 vs.1.27,P＜0.05).Restricted cubic spline analysis revealed a reverse L-shaped association between the TyG index and CVD risk in the overall population(P＜0.001 for nonlinear trend),with risk increasing after the TyG index exceeded 8.67.However,the threshold varied by gender,with a lower threshold in women(8.51)than in men(8.67).Conclusion:A significant nonlinear relationship was revealed between the TyG index and CVD risk,with a threshold effect.The risk of CVD increased once the TyG index surpassed a certain threshold,with a lower threshold in women than in men.These findings suggest that cardiovascular risk prediction and interven-tions based on the TyG index should be gender-stratified,and early intervention for individuals under 60 years old might have important public health implications.

Objective To investigate the expression level and clinical significance of circular RNAs(circRNAs)in serum extracellular vesicles(EVs)of patients with recurrent spontaneous abortion(RSA).Methods The serum samples from 3 RSA patients and 3 nor-mal pregnant women(controls)visited our hospital from May 2021 to March 2023 were collected and the gene expression profiling chips were used to screen for differentially expressed circRNAs in serum EVs.Ten RSA patients and 10 normal pregnant women were enrolled in a training set and 80 RSA patients and 64 normal pregnant women were enrolled in a validation set.Real-time quantitative polymerase chain reaction(qRT-PCR)was used to detect the levels of differentially expressed circRNAs between the two groups.The predictive value of differentially expressed circRNAs for RSA was evaluated by the receiver operating characteristic(ROC)curve.Results A total of 57 563 circRNAs in serum EVs were detected by the gene expression profiling chips.Compared with the control group,3 516 circRNAs were differentially expressed in RSA patients,including 2 377 up-regulated and 1 139 down-regulated.The de-tection results of qRT-PCR in the training set and validation set showed that the expression levels of hsa＿circ＿0054403 in serum EVs of RSA patients(2.07[1.00,6.68])was significantly higher than that in the control group(1.00[0.42,1.46],U=1 239,P＜0.01),while those of hsa＿circ＿0020897(0.33[0.11,1.40]vs 1.00[0.46,3.66],U=1 712,P＜0.01)and hsa＿circ＿0072745(0.49[0.22,1.60]vs 1.00[0.51,7.93],U=1 714,P＜0.01)were significantly lower than that in the control group.The ROC curve showed that the hsa＿circ＿0054403,hsa＿circ＿0020897,and hsa＿circ＿0072745 in serum EVs had high predictive value for RSA.Their AUCROC were 0.758,0.666,and 0.664,respectively,and the corresponding sensitivity and specificity were 47.5% and 100.0%,50.0% and 81.2%,and 62.5% and 70.3%,respectively.When the three circRNAs were combined,it's AUCROC,sensitivity,and specificity were 0.842,73.7%,and 79.7%,respectively.Conclusion The hsa＿circ＿0054403,hsa＿circ＿0020897,and hsa＿circ＿0072745 in serum EVs of RSA patients are abnormally expressed,which may serve as the potential markers for predicting RSA.

Objective:To explore the application effect of multidimensional interactive teaching based on the Biggs' 3P model in standardized training of residents in the Department of Stomatology, and evaluate its impact on improving clinical skills, theoretical level, and self-learning ability.Methods:A controlled experimental design was adopted, and 68 resident physicians who received standardized training in the Department of Stomatology from September 2022 to August 2024 were selected as the research subjects. They were divided into an observation group and a control group, with 34 residents in each group. In terms of teaching methods, the control group received traditional linear progressive teaching, which included theoretical teaching, operational demonstration, group training, and clinical operation. The observation group received multidimensional interactive teaching based on the Biggs' 3P model, which systematically integrated presage, process, and product. The teaching effectiveness was evaluated through theoretical and practical assessment scores, a self-learning ability scale, and a questionnaire. Chi-square test and t test were performed using SPSS 26.0. Results:The observation group achieved significantly higher scores in both theoretical and practical assessments. The total score of theoretical assessment was significantly higher in the observation group than in the control group [(82.65±6.55) vs. (74.26±7.41)], especially in areas reflecting clinical thinking such as multidisciplinary collaborative design of diagnosis and treatment plans [(6.62±0.51) vs. (5.31±0.58)]. In the practical operation assessment, the total score of the observation group (83.19±7.65) was higher than that of the control group (75.36±6.33), with particularly significant differences in clinical emergency response ability assessments such as simulated dentistry emergency management. In addition, the self-learning ability scores in all dimensions of the observation group were higher than those of the control group. According to the teaching experience survey, 94.12%( n=32) of the observation group students believed that the new teaching mode effectively improved their learning interest, and 91.18%( n=31) approved the personalized design of the teaching method. Conclusions:The multidimensional interactive teaching program based on the Biggs' 3P model can improve the effectiveness of standardized training of dental resident physicians, and demonstrate high efficiency in enhancing theoretical knowledge mastery, clinical skills operation, interdisciplinary collaboration ability, and self-learning ability cultivation, providing an innovative teaching mode that can be promoted for training dental specialists.
