Objective To explore the changes in trabecular meshwork cell types and cellular communication patterns in primary open-angle glaucoma(POAG).Methods The POAG single-cell dataset GSE135337(including the trabecular meshwork samples of 3 cynomolgus macaque monkeys with POAG and 3 healthy cynomolgus macaque monkeys,data upda-ted to 2023)was downloaded from the Gene Expression Omnibus(GEO),two groups of samplesare named the POAG group and the control group.The downscaling,clustering,grouping,and visualization of data were performed using the Seurat package in R.The cellular communication pattern was analyzed by using the CellChat package in R to identify the differences in the cellular communication pattern between the POAG group and the control group.Meanwhile,the differen-tial gene analysis was performed based on the transcriptome sequencing(RNA-seq)dataset GSE27276(including the atrial horn tissue samples from 17 POAG patients and 19 healthy individuals,data updated to 2023)from the GEO to identify spe-cific cellular communication signaling changes.Results There were no significant differences in the cell types between the control group and the POAG group,including trabecular meshwork cells,macrophages,melanocytes,pericytes,Schlemm's canal cells,myelinating Schwann cells,nonmyelinating Schwann cells,smooth muscle cells,and vascular en-dothelial cells.There was a significant difference in the cellular communication intensity between the POAG group and the control group.The expression of macrophage migration inhibitory factor(MIF)-CD74,C-X3-C motif chemokine ligand 1(CX3CL1)-C-X3-C motif chemokine receptor 1(CX3CR1),and HBB in the POAG group was significantly up-regulated compared with the control group,while the expression of secreted phosphoprotein 1(SPP1)-(ITGA8+ITGB1),SPP1-(IT-GA4+ITGB1),IGF2-IGF2R,CCL8-CCR1,and CCL8/26/24/2-ACKR2 in the POAG group was significantly down-regulated compared with the control group.The RNA-seq analysis results confirmed that the expression levels of HBB,HBD,HBA,and CD74 were higher in the POAG group than in the control group.Conclusion The up-regulation of MIF-CD74 and the down-regulation of SPP1-(ITGA8+ITGB1)and SPP1-(ITGA4+ITGB1)in trabecular meshwork tissues may participate in the fibrotic process,which may be a potential pathogenic mechanism of POAG.

Objective:To explore the relationship between depression, perfectionism and self-injurious function in adolescents with self-injury.Methods:A total of 6 149 adolescents from two middle schools were selected by multi-stage random sampling method to conduct a cross-sectional investigation, and 530 cases with self-injurious behaviors were screened out as the self-injury group, while the remaining 5 619 students served as the non-self-injury group.The self-rating depression scale, the Chinese-revised Frost multidimensional perfectionism scale, and the Ottawa self-injury inventory Chinese revised version were used for investigation.SPSS 24.0 software was used for descriptive statistics and Spearman correlation analysis, and the PROCESS 4.1 macro program was used for mediating effect test(model 4)and moderating effect test(model 7).Results:(1)The incidence of self-injury among adolescents was 8.62%(530/6 149), which was significantly different in gender( χ2=50.942, P<0.01) and grade( χ2=37.401, P<0.01). (2)The scores of depression(48(41, 55)) and maladaptive perfectionism(64(53, 76)) in the self-injury group were higher than those in the non-self-injury group(36(29, 43), 49(35, 61)), and the differences were statistically significant( Z=-23.233, -18.599, both P<0.01). (3)Adolescents with self-injury mostly had external emotion regulation(70.38%(373/530)) as the dominant function.(4)The results of Spearman correlation analysis showed that self-injurious function was significantly and positively correlated with depression( r=0.382, P<0.01) and maladaptive perfectionism( r=0.356, P<0.01), and depression was significantly and positively correlated with maladaptive perfectionism( r=0.352, P<0.01). (5)Maladaptive perfectionism partially mediated the relationship between depression and self-injurious function( β=0.086, P<0.001), and the mediating effect accounted for 21.88%(0.086/0.393)of the total effect.(6)Gender moderated the first stage of the mediation pathway(depression→maladaptive perfectionism)( β=0.180, P<0.05), which indicated that depression had a stronger predictive effect on maladaptive perfectionism in women( βsimple=0.105, 95% CI=0.063-0.154, P<0.05). Conclusion:In the prediction of depression on self-injurious function, maladaptive perfectionism plays a partial mediating role, and this mediating effect is moderated by gender.

As for the walking violation rate, male students [29% (95%CI: 21%‒37%)] was higher than that of female students [22% (95%CI: 15%‒30%)]. Adolescents in North of China had the highest rate of walking violation [54% (95%CI: 30%‒76%)], of which vocational school students accounted for 38% (95%CI:21%‒56%) of the total violation. In terms of the detection rate of unsafe swimming, male students [18% (95%CI: 14%‒24%)] was higher than that of female students [8% (95%CI: 6%‒10%)]. Adolescents in Central South China had the highest rate of unsafe swimming [15% (95%CI: 12%‒18%)], of which, vocational school students accounted for the highest [15% (95%CI: 10%‒19%)]. When it comes to the prevalence of suicidal ideation, female students [16% (95%CI: 13%‒19%)] was higher than that of male students [13% (95%CI: 11%‒15%)]. Adolescents in Southwest of China had the highest rate of suicidal ideation [17% (95%CI: 10%‒25%)], of which high school students accounted for the highest [15% (95%CI: 12%‒18%)]. Finally, the detection rate of fights was 30% (95%CI: 26%‒34%) for boys and 11% (95%CI: 10%‒14%) for girls. Adolescents from Southwest of China had the highest rate [29% (95%CI: 24%‒34%)] for fights, and junior high school students accounted for the highest [26% (95%CI: 22%‒31%)]. ConclusionThe prevalence of harmful behaviors among adolescents in China is notably high, with statistical differences across gender, region, and school stages. These behaviors pose a risk to adolescent health, underscoring the need for targeted interventions by health and educational authorities.

Objective:To explore the early diagnosis and correct treatment of neurogenic pulmonary edema (NPE) and review the literature.Method:Retrospective analysis was performed in six patients diagnosed as NPE who were admitted to the emergency department of Tianjin Third Central Hospital from March 2017 to March 2021.Results:Six patients had acute onset, presenting severe dyspnea and hypoxemia, and obvious wet rales could be heard in both lungs. The white blood cell count (WBC) increased to varying degrees (11-22)×10 9/L, procalcitonin (PCT) was normal, or slightly increased, sputum bacteriological examination was negative, and oxygenation index was < 200 mmHg (1 mmHg≈0.133 kPa). Chest CT mainly showed patchy or patchy exudation. The lesions were of different sizes and were not distributed according to lobes.
