The phenomenon of adolescent suicide has become a serious challenge to global public health, and suicidal behavior can directly threatening the lives of adolescents.Attempted suicide during adolescence has long-term negative impacts on their health in adulthood.With the continuous development of artificial intelligence technology, machine learning has demonstrated markedly superior performance compared to traditional assessment tools in predicting the risk of suicide among adolescents.Therefore, this article reviews the application and significance of machine learning in predicting suicidal behavior among adolescents.It mainly focuses on machine learning-related concepts, the utilization of multimodal data such as text and voice, as well as the in-depth analysis of algorithmic performance.However, this learning technology continues to encounter challenges pertaining to data quality, overfitting, model interpretability as well as ethical considerations.In future practical applications, various factors, including data characteristics, problem requirements, time costs and algorithm performance, should be comprehensively considered to develop a more accurate predictive model for adolescent suicidal behavior, thereby safeguarding the mental health of adolescents.

Iron,a vital trace element and redox-active metal in the human body,is pivotal in cellular processes and en-gages in a multitude of biological reactions.Ferroptosis,an emerging form of regulated cell death,is predominantly instiga-ted by the excessive free iron that catalyzes reactive oxygen species(ROS)production via the Fenton reaction.This process results in the peroxidation of polyunsaturated fatty acids within the cellular lipid membrane,compromising the membrane's integrity and thereby inducing ferroptosis.In the context of diabetic retinopathy(DR),ferroptosis plays a sig-nificant role.The disruption of iron metabolism,the excessive accumulation of ROS,and the imbalance of the antioxidant system are key mechanisms contributing to ferroptosis in retinal tissues and the exacerbation of DR's pathological progres-sion.This review provides a systematic summary and in-depth discussion of the advancements in understanding the role of ferroptosis in DR pathogenesis,intending to offer valuable insights for future research endeavors in this field.

Objective:To explore the expression of chemokine ligand 1(CCL1)in oral squamous cell carcinoma(OSCC)and its effect on the proliferation,migration and invasion of human oral tongue squamous cell carcinoma cells(HSC-4).Methods:28 OSCC tissue samples and clinical characteristic data of patients were collected at the Affiliated Stomatological Hospital of Southwest Medical University between January 2018 and June 2020,as well as 10 normal gingival tissue samples removed during the extraction of impacted teeth.OSCC cells HSC-4 were cultured routinely and divided into the control group(without virus),the NC group(transfected with control lentiviral vector),the shCCL1 group(transfected with knockdown CCL1 lentiviral vector),and the CCL1 group(culture medium containing 60 ng/mL CCL1 recombinant protein).Immunohistochemistry and WB were used to detect the expression of CCL1 in OSCC tissues and cells,and analyze the correlation between its expression level and the clinical features of patients.qPCR,CCK-8 assay,plate cloning assay,cell scratch test,Transwell assay and flow cytometry were used to detect the expression of CCL1 mRNA,the proliferation,migration and invasion abilities and the apoptosis of HSC-4 cells respectively.Results:CCL1 protein was highly expressed in OSCC tissues and HSC-4 cells(all P<0.01)and its expression was related to the clinical stage of tumors(P<0.05).The expression of CCL1 in HSC-4 cells was successfully knocked down(P<0.000 5).Knocking down the expression of CCL1 could inhibit the proliferation(P<0.05 or P<0.01),migration and invasion(all P<0.05)of HSC-4 cells,and promote its apoptosis(all P<0.05).CCL1 recombinant protein treatment resulted in the opposite effects(P<0.05,P<0.01,P<0.000 1).Conclusion:CCL1 is highly expressed in OSCC and its expression is correlated with the clinical stage of OSCC.CCL1 may take part in regulating the proliferation,migration,invasion and apoptosis of HSC-4 cells.

Objective To explore the expression of macrophage colony-stimulating factor(MCSF)in oral squamous cell carcinoma(OSCC)and its effects on the proliferation,apoptosis,and migration of OSCC cells.Methods Normal gingival and OSCC tissues were collected,and MCSF protein expression was detected using immunohistochemistry and Western blotting.HSC-4 cells were divided into control(no transfection),shNC(transfection with sequence-free plasmid vector lentivirus),and shMCSF(transfection with silent MCSF plasmid vector lentivirus)groups.The expression of MCSF mRNA and protein in HSC-4 cells was detected using quantitative real-time PCR and Western blotting,respectively.Scratch and Transwell assays were used to detect the migration ability of HSC-4 cells.The TUNEL assay determined the apoptosis ability of HSC-4 cells,while a colony formation assay detected the proliferation ability of HSC-4 cells.Results MCSF was highly expressed in OSCC tissues and HSC-4 cells but weakly expressed in normal gingival tissues and Hacat cells.The migration and proliferation ability of HSC-4 cells in the shMCSF group was lower than that in the shNC group(P＜0.05).The apoptosis ability of HSC-4 cells in the shMCSF group was higher than that in the shNC group(P＜0.05).Conclusion MCSF is upregu-lated in OSCC tissues,promoting cell migration and proliferation,while also reducing the apoptosis of OSCC cells.

After nearly 40 years of development,MRI has become an important imaging diagnostic method in clinical practice.Non-contrast enhanced MRI combined with contrast-enhanced MRI can provide multidimensional information,significantly improving lesion detectability and supporting the entire disease management cycle.With the decentralization of medical resources,contrast-enhanced MR technologies(such as magnetic resonance angiography,dynamic contrast-enhanced MRI and dynamic susceptibility contrast-enhanced MRI,etc.)have become popular in primary healthcare facilities.As a critical adjunct to contrast-enhanced imaging,high-pressure injection technology for contrast agents plays a determinant role in ensuring imaging quality and diagnostic validity.This technology offers distinct advantages in precise control of injection parameters(flow rate,dosage,timing),maintenance of bolus integrity and enhancement of inter-study reproducibility.However,the absence of standardized international and domestic guidelines for its application currently hinders the harmonization of imaging data and limits cross-institutional interoperability of diagnostic results.To address this gap,an expert group has developed the"Expert Consensus on the Application of High-Pressure Injection Technology for Magnetic Resonance Contrast Agents",referencing domestic and international guidelines and literature,and in conjunction with the current application status in the country.This consensus aims to provide radiology professionals with safe and effective technical application guidance and to promote standardized clinical practice.

OBJECTIVE To investigate the result of human immunodeficiency virus(HIV)screening for the people visiting to a three-A hospital of Sichuan Province and analyze the prevalence of complications with hepatitis B virus(HBV)infection,hepatitis C virus(HCV)infection and Treponema pallidum(TP)infection in the emerging HIV infection patients.METHODS The result of HIV screening for the people who visited to Ziyang Central Hos-pital from Jan.1,2020 to Dec.31,2024 and the test results of HBV,HCV and TP for the emerging HIV infec-tion patients were collected and were summarized and statistically analyzed by SPSS.0 software.RESULTS Totally 289 891 case-times were tested for HIV,1529 cases were previously diagnosed with HIV,465 of whom were tested posi-tive for the first time,there was significant difference in the positive rate of test for the first time among the 5 years(x2=15.998,P=0.003).Totally 353 cases were confirmed positive among the 465 primary positive screening cases.Among the emerging HIV infection patients,the positive rate was higher in the male than in the female(x2=141.141,P＜0.001),and the positive rate was high among the population aged more than 40 year old(x2=11.448,P＜0.001),mi-grant workers(x2=270.110,P＜0.001)and low education level population(x2=25.911,P＜0.001).The detection rate of gp41 was up to 100.00％in strip type testing.The analysis of the ratio of relative light unit(RLU)to Cutoff val-ue(COI)in the initial screening experiment showed that when COI was greater than 50,all of the confirmed tests were positive,when COI ranged between 1 and 5,the false positive rate was 97.06％.The incidence of complica-tion with HBV infection in the emerging HIV infection patients was increased year by year(x2=20.355,P＜0.001),and the incidence of complication with HCV infection was increased in recent two years(x2=10.690,P=0.030).CONCLUSIONS There is no obvious rise of positive rate of HIV screening among the people visiting to the hospital in recent 5 years.The sensitivity of the primary screening of clinical laboratory is high without posi-tive missing test.The positive rates of HBV and HCV are increased among the emerging HIV infection patients.

Meige syndrome is a focal dystonic movement disorder characterized by blepharospasm and oromandibular dystonia. It is a very rare disease. Individuals affected by Meige syndrome usually experience a wide array of complex symptoms including involuntary blinking and spasms of the jaw muscle. Dyspnea is rarely mentioned, due to dystonic spasm affecting the respiratory muscles. We report a case of a 69-year-old man with Meige syndrome, with dyspnea as the main clinical manifestation. Management often involves medications, botulinum toxin injections, and surgery to alleviate symptoms and enhance function. Now we reviewed the relevant literatures and summarized the experience of diagnosis and treatment in Meige syndrome.
