Objective To determine the prognostic biomarkers and new therapeutic targets of the lung adenocarcinoma (LUAD), based on which to establish a prediction model for the survival of LUAD patients. Methods An integrative analysis was conducted on gene expression and clinicopathologic data of LUAD, which were obtained from the UCSC database. Subsequently, various methods, including screening of differentially expressed genes (DEGs), Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis and Gene Set Enrichment Analysis (GSEA), were employed to analyze the data. Cox regression and least absolute shrinkage and selection operator (LASSO) regression were used to establish an assessment model. Based on this model, we constructed a nomogram to predict the probable survival of LUAD patients at different time points (1-year, 2-year, 3-year, 5-year, and 10-year). Finally, we evaluated the predictive ability of our model using Kaplan-Meier survival curves, receiver operating characteristic (ROC) curves, and time-dependent ROC curves. The validation group further verified the prognostic value of the model. Results The different-grade pathological subtypes' DEGs were mainly enriched in biological processes such as metabolism of xenobiotics by cytochrome P450, natural killer cell-mediated cytotoxicity, antigen processing and presentation, and regulation of enzyme activity, which were closely related to tumor development. Through Cox regression and LASSO regression, we constructed a reliable prediction model consisting of a five-gene panel (MELTF, MAGEA1, FGF19, DKK4, C14ORF105). The model demonstrated excellent specificity and sensitivity in ROC curves, with an area under the curve (AUC) of 0.675. The time-dependent ROC analysis revealed AUC values of 0.893, 0.713, and 0.632 for 1-year, 3-year, and 5-year survival, respectively. The advantage of the model was also verified in the validation group. Additionally, we developed a nomogram that accurately predicted survival, as demonstrated by calibration curves and C-index. Conclusion We have developed a prognostic prediction model for LUAD consisting of five genes. This novel approach offers clinical practitioners a personalized tool for making informed decisions regarding the prognosis of their patients.

Objective: To explore the potential category patterns of risk prevention and control behaviors of HIV infection among young students who have sex with men (MSM) and their impact on HIV infection and late detection, aiming to optimize intervention strategies. Methods: From September 2017 to December 2024, a total of 1 637 MSM young students in Tianjin were recruited through both online and offline channels. Latent class analysis was applied to classify 11 HIV risk prevention and control behaviors [condom use during the most recent anal sex in the past 6 months, consistent condom use, use of water based lubricants, abstinence from recreational drugs, regular on site professional testing, fixed sexual partners, partner testing, awareness of partner s HIV testing results, testing before sexual activity, nucleic acid testing, and use of pre exposure prophylaxis (PrEP) or post exposure prophylaxis (PEP)]. Multivariate Logistic regression analyzed associations between demographic characteristics/intervention services factors and latent classes. Differences in HIV infection and late detection across behavior patterns were compared. Results: HIV risk prevention and control behaviors among MSM students were classified into three latent classes:condom dependent group (38.42%), low prevention group (27.73%), and comprehensive prevention group (33.85%). Students who received condom promotion/testing services were more likely to belong to the comprehensive prevention group ( OR =5.58), while those who received peer education were less likely to the comprehensive prevention group ( OR =0.43) (both P <0.01). Among the MSM student population, the HIV infection rate was 4.83%, with 2.26% of cases detected late. The HIV infection rate (1.45%) and late detection proportion (0.82%) in the comprehensive prevention group were lower than those in the low prevention group (7.89% and 3.83%, respectively) ( χ 2=16.20, 7.31, both P <0.01). Conclusions HIV risk prevention and control behaviors among MSM young students exhibit significant heterogeneity. Comprehensive prevention strategies can effectively reduce HIV infection and late detection risks. It is necessary to optimize peer education content and improve the accessibility of diversified prevention measures such as PrEP/PEP to enhance HIV prevention and control.

Background::While type 2 diabetes mellitus (T2DM) is considered a putative causal risk factor for coronary artery disease (CAD), the intrinsic link underlying T2DM and CAD is not fully understood. We aimed to highlight the importance of integrated care targeting both diseases by investigating the phenotypic and genetic relationships between T2DM and CAD.Methods::We evaluated phenotypic associations using data from the United Kingdom Biobank ( N = 472,050). We investigated genetic relationships by leveraging genomic data conducted in European ancestry for T2DM, with and without adjustment for body mass index (BMI) (T2DM: Ncase/ Ncontrol = 74,124/824,006; T2DM adjusted for BMI [T2DM adjBMI]: Ncase/ Ncontrol = 50,409/523,897) and for CAD ( Ncase/ Ncontrol = 181,522/984,168). We performed additional analyses using genomic data conducted in multiancestry individuals for T2DM ( Ncase/ Ncontrol = 180,834/1,159,055). Results::Observational analysis suggested a bidirectional relationship between T2DM and CAD (T2DM→CAD: hazard ratio [HR] = 2.12, 95% confidence interval [CI]: 2.01–2.24; CAD→T2DM: HR = 1.72, 95% CI: 1.63–1.81). A positive overall genetic correlation between T2DM and CAD was observed ( rg = 0.39, P = 1.43 × 10 -75), which was largely independent of BMI (T2DM adjBMI–CAD: rg = 0.31, P = 1.20 × 10 –36). This was corroborated by six local signals, among which 9p21.3 showed the strongest genetic correlation. Cross-trait meta-analysis replicated 101 previously reported loci and discovered six novel pleiotropic loci. Mendelian randomization analysis supported a bidirectional causal relationship (T2DM→CAD: odds ratio [OR] = 1.13, 95% CI: 1.11-1.16; CAD→T2DM: OR = 1.12, 95% CI: 1.07-1.18), which was confirmed in multiancestry individuals (T2DM→CAD: OR = 1.13, 95% CI: 1.10-1.16; CAD→T2DM: OR = 1.08, 95% CI: 1.04-1.13). This bidirectional relationship was significantly mediated by systolic blood pressure and intake of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, with mediation proportions of 54.1% (95% CI: 24.9-83.4%) and 90.4% (95% CI: 29.3-151.5%), respectively. Conclusion::Our observational and genetic analyses demonstrated an intrinsic bidirectional relationship between T2DM and CAD and clarified the biological mechanisms underlying this relationship.

Aim To dynamically characterize neuronal damage in the cortex and hippocampus of mice follow-ing acute cerebral ischemia/reperfusion(I/R).Meth-ods Male C57BL/6J mice weighing 25-28 g under-went middle cerebral artery occlusion using the fila-ment method,followed by 1 hour of reperfusion to es-tablish the acute cerebral I/R injury mouse model.The experiment comprised a sham surgery group,I/R-6 h group,I/R-24 h group,and I/R-72 h group.Longa neurological function score was used to assess the neu-rological function.Triphenyltetrazolium chloride(TTC)staining was conducted to detect cerebral in-farct volume.Hematoxylin and eosin(HE)staining was utilized to observe brain tissue pathological dam-age.Nissl staining was performed to evaluate neuronal damage.Immunofluorescence histochemistry staining was employed to assess the activation of astrocytes and microglia,as well as neuronal loss.Transmission elec-tron microscopy was used to examine mitochondrial damage in hippocampal neurons.Western blot analysis was conducted to detect the expression levels of mito-chondrial fission-fusion-related proteins p-Drp1/Drp1,Mff,Fis1,and OPA1.Results With prolonged cere-bral I/R time,neurological functional impairment,cerebral infarct volume,neuronal damage in the cortex and hippocampus,glial cell activation,neuronal loss,and mitochondrial damage gradually worsened in mice.The expression of mitochondrial fission-related proteins increased gradually,while the expression of mitochon-drial fusion-related proteins decreased gradually.Con-clusions Neuronal pathological damage,such as glial cell activation,neuronal loss,and mitochondrial dam-age,is gradually aggravated with prolonged cerebral I/R time,which may be associated with mitochondrial dynamics imbalance.

Objective:To investigate the effect of melatonin on the expression of PD-L1 on the surface of ovarian cancer cells.Methods:Ovarian cancer cell line OVCAR3 was treated with melatonin,then flow cytometry was used to detect the expression level of PD-L1 on the surface of ovarian cancer cells.Western blot was used to detect the expressions of PD-L1 and LC-3 in ovarian cancer cells after different treatments.After adding autophagy inhibitor Autophinib,flow cytometry was used to detect the expression of PD-L1 on the surface of ovarian cancer cells,ovarian cancer cells were treated with melatonin or melatonin combined with autophagy inhibi-tors and co-incubated with human T lymphocyte Jurkat.The proportion of ovarian cancer cell apoptosis was detected by flow cytometry.Results:Melatonin treatment significantly reduced expression of PD-L1 on the surface of ovarian cancer cells,promoted autophagy of ovar-ian cancer cells.Autophagy inhibitors reversed down regulation of PD-L1 treated by melatonin,Jurkat cells killed more melatonin treated ovarian cancer cells,and the killing of ovarian cancer cells by Jurkat cells revised by autophagy inhibitors.Conclusion:Mela-tonin can enhance the killing effect of T cells on ovarian cancer cells.

Objective:To analyze the clinical characteristics and prognosis of patients with stiff-person syndrome (SPS) associated with glutamic acid decarboxylase (GAD) antibodies.Methods:A retrospective analysis was conducted on demographic characteristics, clinical manifestations, auxiliary examination results, treatment, and prognosis of patients with GAD antibody-related SPS treated at Peking Union Medical College Hospital from January 2015 to July 2023.Results:A total of 33 patients were included, comprising 26 females (78.8%) and 7 males (21.2%), with an onset age of (42±12) years and a disease duration of 24.0 (10.5, 37.5) months. Two cases (6.1%) were diagnosed with tumors, including 1 case with invasive thymoma and 1 case with small cell lung cancer. The majority of patients (87.9%, 29/33) presented with stiffness of trunk and proximal limb muscles, 42.4% (14/33) of patients exhibited episodic spasm, and 54.5% (18/33) of patients were triggered by stimuli such as sound and light. Babinski or Chaddock reflexes were elicited in 33.3% (11/33) of patients. Some patients (36.4%, 16/33) had concurrent limbic encephalitis/epilepsy or cerebellar ataxia (referred to as complex SPS). The median cerebrospinal fluid (CSF) white blood cell count was 2×10 6/L [quartile: 1×10 6/L, 6×10 6/L; range: (0-30)×10 6/L], with mild elevation in 28.0% (7/25) of patients. Multi-channel surface electromyography in 14 out of 21 cases (66.7%) suggested synchronous contraction of agonist and antagonist muscles in a relaxed state. The modified Rankin Scale (mRS) score during the acute phase was 4 (3, 4). All patients received treatment with benzodiazepines or baclofen. Thirty patients (90.9%, 30/33) received first-line immunotherapy, 3 patients (9.1%, 3/33) received second-line immunotherapy with rituximab, and 14 (42.4%, 14/33) received mycophenolate mofetil as long-term immunotherapy. The follow-up period was 16 (10, 42) months, with a median best mRS score of 2; 66.7% (22/33) of patients had a favorable functional prognosis (mRS score≤2), and the recurrence rate was 30.0% (9/30). At the last follow-up, the median mRS score was 2, and 53.3% (16/30) of patients had a favorable functional prognosis. Prognosis was not significantly correlated with gender, age, clinical type, or CSF white blood cell level (all P>0.05). Conclusions:SPS is one of the main clinical phenotypes of GAD antibody-related neuroimmune diseases, commonly observed in middle-aged women, and exhibits a chronic progressive course. Only a minority of patients have concomitant tumors. The diagnosis relies on typical symptoms, GAD antibody testing, and electromyography examination. The initial immune therapy yields good results, but the prognosis for recurrent patients is poor.

Objective:To investigate the clinical and genetic characteristics of a child with microcephaly-capillary malformation syndrome due to a STAMBP mutation. Methods:The clinical data of a case of microcephaly-capillary malformation syndrome caused by STAMBP gene mutation admitted to Anhui Children′s Hospital in August 2023 were collected. The genes of the child and his parents were detected by whole exome sequencing, and the risk was predicted by biological software. At the same time, the clinical characteristics of the child were analyzed and the literature was reviewed. Results:The patient is a male child aged 2 years and 7 months. The patient had special features, microcephaly, refractory epilepsy, severe comprehensive developmental delay, and capillary malformations. The results of genetic testing showed that the STAMBP gene in the child had complex heterozygous mutations NM_001353967: c.367delG[p.E123fs *27(p.Glu123fsTer27) and c.159A>C(p.Glu53Asp)], inherited from his mother and father respectively. The mutations have not been recorded in the HGMD, dbSNP and gnomAD databases,etc. The protein structure of the STAMBP gene was modeled that predicted c.367del(p.Glu123Lysfs *27) and c.159A>C (p.Glu53Asp) had a negative effect on the function of STAMBP protein. Conclusion:The STAMBP gene complex heterozygous mutations c.367delG(p.Glu123fsTer27) and c.159A>C(p.Glu53Asp) may be the pathogenic factor of this child, which further expands the variation spectrum of the STAMBP gene and the genotype of microcephaly-capillary malformation syndrome, and provides guidance for family genetic counseling.
