Background Acne treatment cycle lasts long and will cause facial appearance damage.Many patients are prone to psychological problems and severe patients may even experience suicidal ideation.However,the influencing factors of psychological health problems in acne patients are still unclear.Objective To investigate the mental health status of patients with moderate-to-severe acne and to analyze the influencing factors of their psychological health problems,so as to provide references for improving their mental health.Methods A total of 120 patients with moderate-to-severe acne of grades II-IV were selected as the research subjects,who were treated in the dermatology outpatient department of the Third Hospital of Mianyang from June 2021 to June 2023.All subjects were evaluated by using the Acne-Specific Quality of Life Questionnaire(Acne-QoL),Self-rating Depression Scale(SDS),Self-rating Anxiety Scale(SAS),Rosenberg Self-Esteem Scale(RSES)and Social Phobia Inventory(SPIN).According to the evaluation results of SDS,SAS,RSES,SPIN,subjects were divided into a group with mental health problems(n=21)and a group without mental health problems(n=99).Binary Logistic regression anaylsis was adopted to explore the influencing factors of psychological health problems in acne patients.Results A total of 21 patients(17.50%)were detected to have symptoms of depression,anxiety,inferiority or social dysfunction.Statistically significant difference was observed in comparison between two groups in gender,profession,acne classification,dietary habit,age,illness course as well as the factor scores of self perception,emotional function,social function and acne symptom in Acne-QoL(χ2=7.013,23.123,9.028,11.327,t=9.913,13.022,4.081,5.383,5.361,10.203,P<0.05).The results of binary Logistic regression analysis showed that the followings were risk factors for the occurrence of psychological health problems in acne patients:female(OR=2.243,95%CI:1.136～4.429),acne of grade III(OR=3.615,95%CI:1.269～10.295)or IV(OR=1.872,95%CI:1.073～3.266),course of disease≥1.6 years(OR=2.499,95%CI:1.068～5.851),a spicy or greasy diet(OR=3.811,95%CI:1.169～12.427),Acne-QoL self perception score≤18(OR=1.802,95%CI:1.227～2.646),Acne-QoL emotional function score≤18(OR=2.252,95%CI:1.016～4.992),Acne-QoL social function score≤14(OR=3.515,95%CI:1.534～8.053)and Acne-QoL acne symptom score≤18(OR=3.586,95%CI:1.098～11.715).Protective factors for psychological health problems in acne patients included age over 30 years old(OR=0.429,95%CI:0.283～0.648),occupation as professional cadre or enterprise employee(OR=0.483,95%CI:0.249～0.939)and other occupations(OR=0.276,95%CI:0.090～0.850).Conclusion A part of patients with moderate-to-severe acne may experience psychological health problems.Patients with female gender,higher acne grades,longer disease duration,preference for greasy or spicy foods and lower scores in all Acne-QoL factors have a higher risk of experiencing psychological health problems.

Objective:To investigate the alteration of m6A demethylase AlkB homolog 5 (ALKBH5) expression and its impact on form-deprivation myopia (FDM) retina in guinea pigs.Methods:Thirty normal SPF grade 3-week-old tricolor guinea pigs were randomly divided into normal control group and experimental group, with 15 in each group.In the experimental group, the right eyes were covered as FDM group and the left eyes uncovered were set as self-control group.Ocular biometry was performed at one-week intervals from baseline to week 4 of the experiment.Spherical equivalent was detected by streak retinoscopy and axial length was measured by A-scan ultrasonography.Animals were sacrificed after 4 weeks of modeling.The distribution and expression of ALKBH5 protein in the guinea pig retina was detected by immunohistochemical and immunofluorescence staining.Expression of ALKBH5 mRNA and protein in guinea pig retina was detected by real-time fluorescence quantitative PCR and Western blot, respectively.The use of animals in ophthalmic and vision research followed the tenets of Animal Research in Vision and Ophthalmology, and the study was approved by the Ethics Committee of North Sichuan Medical College (No.2023087).Results:At weeks 2, 3, and 4 after myopia induction, diopters and axial lengths were significantly higher in the FDM group than in the normal control group and the self-control group (all at P<0.001). Immunohistochemistry and immunofluorescence assays showed that ALKBH5 protein was expressed in the retinal nerve fiber layer, rod/cone photoreceptor cells, and retinal pigment epithelium (RPE) layer, and was highly expressed in the retinal nerve fiber layer and RPE layer.The relative ALKBH5 immunofluorescence intensity in the normal control group, self-control group and FDM group was 1.000±0.204, 0.874±0.076 and 0.571±0.053, respectively, which was lower in the FDM group than in the normal control and self-control groups, showing statistically significant differences ( t=4.069, P=0.006; t=5.176, P=0.014). After 4 weeks of modeling, ALKBH5 mRNA and protein expressions were significantly lower in FDM group than in normal control and self-control groups (both at P<0.01). Conclusions:The expression of m6A demethylase ALKBH5 is decreased in the retina of FDM guinea pigs, suggesting that ALKBH5 and related m6A methylation modification may be involved in the development and progression of myopia.

[Objective]To summarize the clinical experience of Professor JIA Yingjie,a renowned traditional Chinese medicine practitioner in the treatment of esophageal cancer.[Methods]Through clinical following up,collect and analyze Professor JIA's understanding of the etiology and pathogenesis of esophageal cancer and related medication,and a case of was attached as evidence.[Results]Professor JIA believes that the pathogenesis of esophageal cancer can be summarized as"phlegm coagulation and Qi stagnation"in the early stage,"primitive deficiency"in the late stage as a whole,"phlegm and blood stasis intermingle,Qi and blood stasis obstruct the diaphragm"in local areas,phlegm,Qi,and blood stasis solidify and poison transform into cancer turbidity,and block and form tumors.Clinical differentiation and treatment should always focus on"Qi",with a particular emphasis on regulating the"Qi mechanism".The lungs,spleen and liver are in sync,and dynamic differentiation and treatment should be carried out based on the characteristics of the patient's tongue and pulse.Medication should emphasize the use of"strengthening the body resistance righting"and"dispelling pathogenic factors"to achieve the dissipation of blood stasis,the elimination of cancer toxins and the opening of the diaphragm.[Conclusion]Based on the characteristics of esophageal cancer and the patient's physical constitution,Professor JIA combines disease and syndrome differentiation in treating esophageal cancer,providing a certain reference value and new path for clinical medication.

Molecular knowledge of human gastric corpus epithelium remains incomplete. Here, by integrated analyses using single-cell RNA sequencing (scRNA-seq), spatial transcriptomics, and single-cell assay for transposase accessible chromatin sequencing (scATAC-seq) techniques, we uncovered the spatially resolved expression landscape and gene-regulatory network of human gastric corpus epithelium. Specifically, we identified a stem/progenitor cell population in the isthmus of human gastric corpus, where EGF and WNT signaling pathways were activated. Meanwhile, LGR4, but not LGR5, was responsible for the activation of WNT signaling pathway. Importantly, FABP5 and NME1 were identified and validated as crucial for both normal gastric stem/progenitor cells and gastric cancer cells. Finally, we explored the epigenetic regulation of critical genes for gastric corpus epithelium at chromatin state level, and identified several important cell-type-specific transcription factors. In summary, our work provides novel insights to systematically understand the cellular diversity and homeostasis of human gastric corpus epithelium in vivo.

Objective: To analyze the situation of AIDS knowledge and discrimination among freshmen in Chengdu city, and to explore possible effects of AIDS knowledge on discrimination. Methods: A cluster random sampling was employed to investigate 1 053 college students from 11 universities in Chengdu about their HIV/AIDS knowledge and discrimination. The scores of AIDS knowledge and discrimination of students with different characteristics were analyzed, and the influence path of AIDS knowledge on AIDS discrimination were further analyzed based on different peer relationships. Results: The total scores of AIDS knowledge was negatively correlated to AIDS discrimination( r s =-0.13, P <0.01). After adjusting for confounding factors, the total score of AIDS knowledge was associated with the total score of AIDS discrimination( β =-0.12, P <0.01). AIDS knowledge played a role in AIDS discrimination in intimate, general and unfamiliar peer relationships, with standardized path coefficients of -0.20, -0.24 and -0.18 respectively( P <0.01). Conclusion AIDS knowledge are correlated with discrimination among freshmen under different peer relationships. More anti-AIDS discrimination courses should be added to AIDS education to reduce the students’ fear and stigma of HIV/AIDS patients and related risk groups.
