Objective: To explore the association between meat consumption and anxiety symptoms in first year junior high school students in Yunnan Province, and to provide theoretical support for preventing and relieving anxiety symptoms in junior high school students. Methods: From October to December 2022, a random cluster sampling method was used to select 8 500 first year junior high school students from 11 counties in Yunnan Province as the survey subjects for a questionnaire survey. The study used Food Frequency Questionnaire and the Chinese version of the Depression Anxiety Stress Scale-21 (DASS-21) to assess the meat consumption and anxiety symptoms of junior high school students.The distribution differences in anxiety symptoms among first year junior high school students with different demographic characteristics were analyzed statistically by using the Chi-square test,and the association between meat consumption and anxiety symptoms in students was analyzed by using a generalized linear model. Results: The detection rate of anxiety symptoms was 48.47%. After controlling for demographic variables and confounding factors, the consumption of livestock meat, poultry meat, processed meat, cured meat, barbecued meat and raw skin meat was statistically significant with anxiety symptoms ( β =-0.05, 0.04, 0.04, 0.08, 0.14, 0.17, all P <0.05). Stratified by ethnicity, The consumption of livestock meat, cured meat and barbecue was statistically correlated with anxiety symptoms in Han adolescents ( β =-0.07, 0.14, 0.22 ); the consumption of processed meat and raw skin meat was statistically correlated with anxiety symptoms in ethnic minority adolescents ( β =0.08, 0.18) (all P <0.05). Conclusions There is a statistical association between meat comsumption and the risk of anxiety symptoms in first year junior high school students in Yunnan Province. Guidance on meat consumption should be strengthened to prevent the occurrence of anxiety symptoms.

ObjectiveTo investigate the efficacy of selective internal radiation therapy （SIRT） in patients with unresectable hepatocellular carcinoma， and to provide a reference for the selection of clinical treatment regimens. MethodsA retrospective analysis was performed for the clinical data of 73 patients with unresectable hepatocellular carcinoma who received yttrium-90 microsphere SIRT in Eastern Hepatobiliary Surgery Hospital from May 1， 2023 to September 1， 2024. According to tumor characteristics， physical status， liver reserve function， laboratory tests， and SIRT treatment strategy， the patients were divided into radiation segmentectomy group with 9 patients， conversion therapy group with 47 patients， and palliative treatment group with 17 patients. Based on the results of postoperative follow-up， modified Response Evaluation Criteria in Solid Tumors were used to assess radiographic images. A one-way analysis of variance was used for comparison of normally distributed continuous data between three groups， and the chi-square test was used for comparison of categorical data between three groups； the Logistic regression model was used to perform the multivariate analysis. ResultsThere was a significant difference in postoperative outcome between the radiation segmentectomy group， the conversion therapy group， and the palliative treatment group （χ²=30.060， P<0.001）. The disease control rate was 100.0% （9/9） in the radiation segmentectomy group， 83.0% （39/47） in the conversion therapy group， and 29.4% （5/17） in the palliative treatment group， with a significant difference between the three groups （χ²=19.575， P<0.001）， and there was also a significant difference in objective response rate between the three groups （χ²=17.749， P<0.001）. The multivariate Logistic regression analysis showed that the number of tumors （odds ratio ［OR］=0.085， 95% confidence interval ［CI］： 0.008 — 0.906， P=0.041） and combined targeted immunotherapy （OR=18.808， 95%CI： 1.704 — 207.616， P=0.017） were independent influencing factors for achieving complete response. ConclusionThe number of tumors is an independent influencing factor for the efficacy of SIRT and is an important basis for selecting different treatment goals. SIRT combined with targeted immunotherapy may achieve better efficacy.

Constipation,a common functional gastrointestinal disorder,not only severely impairs patients'quality of life but is also highly comorbid with psychiatric conditions such as anxiety and depression.Emerging evidence indicates that gut microbiota dysbiosis is a critical link connecting these two disease states.On one hand,dysbiosis exacerbates constipation by affecting host metabolism and intestinal function;on the other,it plays a central role in the pathophysiology of mood disorders.This complex interaction is primarily mediated through the"microbiota-gut-brain axis."Therefore,elucidating the intrinsic relationship among anxiety,depression,gut microbiota,and constipation has become a frontier of interdisciplinary research.

Objective To investigate the relationship between serum levels of tumor necrosis factor-related protein 5(CTRP5),fibronectin-3(Ficolin-3),and CXC chemokine ligand 12(CXCL12)and microvascular lesions in patients with type 2 diabetes mellitus(T2DM).Methods A total of 75 patients with T2DM microangiopathy admitted to the Seventh People's Hos-pital of Zhengzhou from January 2023 to June 2024 were selected as the observation group.At the same time,150 T2DM pa-tients without microangiopathy were included as the control group according to the principle of 1∶2 matching of age,gender and body mass index(BMI).The general information,blood glucose indicators,Homa-insulin resistance(HOMA-IR),and serum CTRP5,Ficolin-3,and CXCL12 levels of the two groups were statistically analyzed by hospital medical staff.The Logistic re-gression equation was used to analyze the influencing factors of the onset of microvascular lesions in T2DM.The relationship be-tween the levels of serum CTRP5,Ficolin-3,and CXCL12 and microvascular lesions in T2DM was analyzed using smooth curve fitting method.The receiver operating characteristic(ROC)curve and area under the curve(AUC)were used to analyze the pre-dictive value of serum CTRP5,Ficolin-3,and CXCL12 for T2DM microvascular lesions.Results There were no significant differences in gender,age,BMI,duration of T2DM,abdominal circumference,DBP,SBP,TC,HDL-C,TG,LDL-C,smoking his-tory and drinking history between the two groups(all P＞0.05).FPG,2hPG,HbA1c and HOMA-IR in the observation group were significantly higher than in the control group(all P＜0.05).The serum levels of CTRP5,Ficolin-3 and CXCL12 in the ob-servation group were significantly higher than in the control group(all P＜0.05).Logistic regression analysis showed that FPG,2hPG,HbA1c,HOMA-IR,CTRP5,Ficolin-3 and CXCL12 were the influencing factors of T2DM microangiopathy(all P＜0.05).After adjusting for FPG,2hPG,HbA1c,HOMA-IR and other confounding factors,the relationship between serum Fico-lin-3,CTRP5,CXCL12 and T2DM microangiopathy was analyzed by curve fitting,the results showed that serum Ficolin-3,CTRP5,CXCL12 were linearly positively correlated with T2DM microangiopathy,with the increase of their levels,the risk of T2DM microangiopathy increased.The ROC curve showed that the AUC of serum Ficolin-3,CTRP5 and CXCL12 levels in pre-dicting T2DM microvascular lesions was 0.756,0.761 and 0.791,respectively.The AUC of combined prediction was 0.931,and the sensitivity and specificity were 90.67％and 80.00％,respectively.Delong test showed that the AUC of combined prediction was significantly greater than that of single prediction(Z=32.123,P＜0.01).Conclusion The changes in serum levels of CTRP5,Ficolin-3,and CXCL12 are closely related to microvascular lesions in patients with T2DM,providing a reference for ear-ly clinical prediction and evaluation of microvascular lesions in patients with T2DM,as well as for the development of corre-sponding intervention strategies.

Objective·To develop a graph neural network(GNN)-based auxiliary diagnostic model for gallbladder cancer on CT images,and validate its accuracy and feasibility.Methods·From January 2010 to November 2023,1 774 contrast-enhanced CT arterial-phase images were acquired from 887 patients with normal gallbladder,benign gallbladder disease,or gallbladder cancer at Xinhua Hospital and Renji Hospital,Shanghai Jiao Tong University School of Medicine.These images were randomly divided into training and testing sets at a 4∶1 ratio to develop a hybrid GNN-convolutional neural network(CNN)model,named VJK-GIN.The model constructed a pixel-level graph in which each pixel served as a node,and spatial adjacency defined the edges,enabling extraction of local texture features.In the model architecture design,VJK-GIN integrated a three-layer graph isomorphism network,augmented with virtual nodes and jump-knowledge connections;global pooling compressed node features into a graph-level representation,which was classified by a multi-layer perceptron head.Five-fold cross-validation was used to compare VJK-GIN with GNN baselines(GCN,GraphSAGE,GAT,and GIN)and CNN baselines(ViT,EfficientNetV2,and ConvNeXt)in terms of accuracy,precision,recall,F1-score,and area under the receiver operating characteristic curve(AUC).Results·The results of five-fold cross-validation showed that VJK-GIN achieved an F1-score of 0.799(95%CI 0.775?0.823),recall of 0.795(95%CI 0.773?0.817),precision of 0.799(95%CI 0.775?0.823),AUC of 0.812(95%CI 0.792?0.832),and accuracy of 0.773(95%CI 0.748?0.798),surpassing all competing models across every metric.Conclusion·The VJK-GIN model exhibits high stability and accuracy in identifying contrast-enhanced CT images of normal,benign,and malignant gallbladder conditions.

Atherosclerosis and its complications are one of the diseases with the highest incidence and mortality in the world,and its early diagnosis and treatment are very important.At present,a variety of physiological and biochemical indicators have been used to diagnose atherosclerosis.However,the accuracy and ease of use of existing diagnostic indi-cators still cannot meet the clinical needs,and new,reliable and easy to measure biomarkers for early diagnosis and judg-ment of atherosclerosis and the risk of serious cardiovascular and cerebrovascular events caused by atherosclerosis are still very scarce.This article summarized the latest research progress of biomarkers related to atherosclerosis,such as hematol-ogy,genetics and omics,in order to provide basis for early diagnosis and treatment of atherosclerosis and related cardiovas-cular and cerebrovascular diseases induced by atherosclerosis.

AIM:To evaluate the pharmacokinet-ics(PK)and pharmacodynamics(PD)of two recom-binant human insulin injection by euglycemic clamp technology in healthy male subjects after a single subcutaneous injection.METHODS:We con-ducted a randomized,open-label,single dose,two period,crossover study.A total of 24 healthy male subjects were enrolled and randomized to receive single subcutaneous doses(0.2 U/kg)of the investi-gational products every period.The PK and PD characteristics were assessed by euglycemic clamp up to 14 hours after dosing.RESULTS:Euglycemic clamp technique was successfully established.C-peptide levels detected at each time point before and after administration indicated that endoge-nous insulin secretion was inhibited in the two groups after administration.The geometric mean ratio of Cmax and AUC0-tand 90％confidence interval(CI)of test preparation and reference preparation under fasting condition were in the range of 80.00％-125.00％.CONCLUSION:The human insulin produced by KP Biotech demonstrated similarity to the reference preparation Humulin? in PK and PD characteristics in healthy Chinese subjects.

Objective:To study the implementation progress of the prevention and control measures for drinking water-borne endemic fluorosis and the changing trend of fluorosis conditions in Inner Mongolia Autonomous Region, comprehensively evaluate the effectiveness of prevention and control measures, and provide a basis for the next step of prevention and control of the disease.Methods:In 2015 and 2023, a cross-sectional survey method was used to investigate the water improvement situation, the operation of water improvement projects, the detection of fluoride level in water, and the prevalence of dental fluorosis in children aged 8 to 12 in all affected villages of 11 leagues (cities) in the entire autonomous region. The prevention and control effect of drinking water-borne endemic fluorosis in the entire autonomous region was evaluated.Results:The water improvement rates of all affected villages in the entire autonomous region in 2015 and 2023 were 84.12% (8 218/9 769) and 95.38% (8 944/9 377), respectively. The qualified rates of water fluoride in the villages with water improvement in the entire autonomous region were 66.21% (5 441/8 218) and 91.00% (8 139/8 944), respectively. The water improvement rate and water fluoride qualification rate of water improvement villages in 2023 were both higher than those in 2015, and the differences were statistically significant (χ 2 = 652.96, 1 593.81, P < 0.001). The detection rates of dental fluorosis in children aged 8 to 12 years in the entire autonomous region in 2015 and 2023 were 9.26% (7 548/81 484) and 4.46% (3 441/77 155), respectively. The detection rate of dental fluorosis in children in 2023 was lower than that in 2015, and the difference was statistically significant (χ 2 = 1 418.20, P < 0.001). In 2015 and 2023, the total compliance rate of all affected villages in the entire autonomous region reaching the control standards were 57.94% (5 660/ 9 769) and 92.37% (8 662/9 377), respectively. The total compliance rate of all affected villages in 2023 was higher than that in 2015, and the difference was statistically significant (χ 2 = 3 010.38, P < 0.001). Conclusions:Compared with 2015, the prevention and control measures of drinking water-borne endemic fluorosis in Inner Mongolia Autonomous Region have been effectively implemented in 2023, with a significant decrease in the detection rate of dental fluorosis in children. However, there are still a few affected villages that have not achieved the control standards, and prevention and control work still need to be further strengthened.
