Objective To investigate the patterns of syndrome changes and their possible material basis in mouse models of chronic psychological stress during the modeling process.Methods A chronic unpredictable mild stress(CUMS)method was employed to prepare a model of chronic psychological stress in mice.After 2 weeks of modeling,Xiaoyao powder(XYS group)and Sini powder(SNS group)were administered concurrently with the modeling process.General conditions,behavioral,and biochemical indicators were compared between the modeling mice(M4 and M6 group)and the mice treated for 2 weeks(S4 and X4 group)and 4 weeks(S6 and X6 group)after chronic psychological stress.Results Compared with M4 group mice,body mass,total distance and central distance in the open field test,serum NE concentration,and gastric Ghrelin expression were increased in S4 group and X4 group mice,and sugar water preference rate and serum D-xylose concentration were increased in S4 group mice.Compared with X4 group mice,total distance in the open field test and serum D-xylose concentration were increased in the S4 group mice.Compared with M6 group mice,body mass,serum NE concentration,serum D-xylose concentration,and gastric Ghrelin expression were increased in group S6 and X6 group mice;sugar water preference rate,total distance in the open field test,and active avoidance counts in the shuttle box test were increased in X6 group mice,while their serum CORT concentration was decreased.Compared with S6 group mice,body mass,total distance in the open field test,serum D-xylose concentration,and gastric Ghrelin expression in X6 group mice were increased.Conclusions During the process of modeling chronic psychological stress in mice,the traditional Chinese medicine syndrome evolved from liver qi stagnation to liver qi stagnation with spleen deficiency.The biological bases of the syndrome changes may be the combined changes in serum CORT and NE concentrations and the decrease in gastric Ghrelin levels.

IL-32 is a multifunctional cytokine with both pro-inflammatory and anti-inflammatory properties.It has been proved that expression of IL-32 increases with progression of gastric mucosal diseases and severity of gastric cancer(GC),thus participating in process of gastric"inflammation-cancer"transformation.However,how IL-32 affects malignant transformation of gastric"inflamma-tion-cancer"and finally leads to adverse outcome of GC invasion and migration is still controversial.In order to better clarify regulatory effect and possible mechanism of abnormal expression of IL-32 on different histopathological stages of gastric"inflammation-cancer"transformation,and to explore new directions and breakthroughs in molecular mechanism of early truncation and treatment of gastric precancerous lesion(GPL),we searched literatures related to IL-32 in six authoritative databases at home and abroad,such as Pubmed,Web of Science and CNKI,in past 30 years.It was found that pathogenicity or protective function of IL-32 in different histo-pathological stages of gastric"inflammation-cancer"transformation depended on its different subtypes,secretory forms,surrounding cytokine environment,disease status and genetic factors.IL-32 may regulate polarization of macrophages through NF-κB,MAPK,COX2,PR3,IDO,NOD,PKCδ,FAK and STAT3,amplify or inhibit chronic inflammatory stimulation of gastric mucosa,and thus participate in process of gastric"inflammation-cancer"transformation.Our new understanding of role of IL-32 in different stages of Cor-rea cascade may contribute to development of cytokine-directed therapy,and therapy aimed at regulating different alternative splicing subtypes of IL-32 and targeting IL-32 signals can be used as a new strategy for medical treatment of GPL and GC in future.

Objective: To delineate the epidemiologic profile of rifampicin resistant pulmonary tuberculosis (RR-PTB) among students in Chongqing, so as to provide evidence for effectively controlling RR-PTB outbreaks in schools. Methods: Individual level surveillance records of 395 student RR-PTB cases reported from 2015 to 2024 were extracted from the China Information System for Disease Control and Prevention. The Joinpoint regression analysis was employed to quantify temporal trends in the registration rate of student RR-PTB cases, and the comparison of RR-PTB registration rates with different demographic characteristics and different regions was performed using Chi-square test. Results: From 2015 to 2024, a total of 395 student RR-PTB cases were identified, with the registration rate ranged from 0.07 per 100 000 to 1.47 per 100 000, showed a fluctuating upward trend ( AAPC= 35.22%, t =4.13, P <0.01). A turning point was detected in 2017, rates rose during 2015-2017 (APC=295.23%， t =4.62， P < 0.01 ) and plateaued thereafter (APC=-0.47%， t =-0.12， P =0.91). The proportion of RR-PTB cases occurring among students increased both among all RR-PTB cases (1.54% in 2015, 7.48% in 2024) and all student pulmonary tuberculosis cases (0.20% in 2015, 7.17% in 2024), with significant linear trends ( χ 2 trend =33.55,159.98, both P <0.01). The majority of cases were enrolled in senior high school (50.38%), classified as retreatment (53.92%), of Han ethnicity (75.95%), and diagnosed with multidrug resistant tuberculosis(53.16%). There were significant differences in the composition of different ethnicity, registration category and resistance pattern between different years( χ 2=23.47, 17.23, 59.64，all P <0.05). The South-Eastern Wuling Mountainous Region exhibited the highest notification rate (3.96 per 100 000), whereas the western region had the lowest rate ( 0.47 per 100 000). County level jurisdictions reported higher rates than district level ones (2.16 per 100 000 vs 0.63 per 100 000 ). Statistically significant differences were observed in the RR-PTB reported rates among students across different districts and counties( χ 2=418.05,167.05,both P <0.01). Conclusions From 2015 to 2024, the registration rate of detected student RR-PTB cases in Chongqing showed an increasing trend. Students have become one of the key populations for drug resistant TB prevention and control. Intensified health education and active case finding should be implemented to enhance proactive surveillance capabilities.

Objective:To investigate the incidence and influencing factors of optic disc changes in children and adolescents with high myopia.Methods:A clinical cross-sectional study. A total of 162 children and adolescents with high myopia (162 eyes) who visited Department of Ophthalmology, Northern Jiangsu People's Hospital Affiliated to Yangzhou University from January to April 2025 were included in this study. Myopia refractive error ≥6.00 D and/or axial length (AL) ≥26 mm. All participants underwent best-corrected visual acuity, refraction, fundus color photography, swept-source optical coherence tomography (SS-OCT), and AL measurement. Subfoveal choroidal thickness (ChT) was measured within 1 mm using SS-OCT. Optic disc changes assessed included tilt, rotation, peripapillary atrophy (PPA), and peripapillary hyperreflective ovoid mass-like structures (PHOMS). The patients were divided into the children group (4-11 years old) and the adolescents group (12-18 years old) based on age, with 63 (38.9%, 63/162) and 99 (61.1%, 99/162) cases respectively. The incidence of ocular features and optic disc morphology changes in the two groups was compared and observed. According to the myopia diopter, the patients were divided into the high diopter long axial group (myopia diopter ≥6.00 D, AL≥26 mm) and the low diopter long axial group (myopia diopter <6.00 D, AL≥26 mm), with 85 (52.5%, 85/162) and 77 (47.5%, 77/162) eyes respectively. The incidence of optic disc morphological changes in the two groups was compared and observed. The comparison of quantitative data between groups was conducted using the Mann-Whitney U test. Multivariate logistic regression was used to analyze the correlations between PPA, optic disc tilt, PHOMS occurrence and gender, age, diopter, AL, and ChT. Results:Among the 162 patients, 103 were male and 59 were female. Age was 12 (10.5, 13.5) years old. Among the 162 eyes, the optic disc morphology changed in 152 eyes (93.8%, 152/162). Among them, the PPA, optic disc tilt, PHOMS, and optic disc rotation were 148 (91.4%, 148/162), 95 (58.6%, 95/162), 62 (38.3%, 62/162), and 35 (21.6%, 35/162) eyes respectively. Myopic macular degeneration in 137 eyes. There were 56 eyes with peripheral retinopathy. There was no statistically significant difference in myopia diopter, AL and ChT between the children group and the adolescent group ( Z=-1.201, -1.934, ?0.761; P=0.230, 0.053, 0.447). There was no statistically significant difference in the incidences of PPA, optic disc tilt and optic disc rotation ( χ2=0.293, 2.618, 0.398; P>0.05). There was no statistically significant difference in the incidence of optic disc morphological changes between the low diopter long axial group and the high diopter long axial group ( χ2=0.000, P>0.05). The results of multivariate logistic regression analysis showed that the thinner the ChT, the higher the risk of PPA [odds ratio (OR) =0.98, 95% confidence interval ( CI) 0.97-0.99, P<0.001]. Female ( OR=2.3, 95% CI 1.04-5.07, P=0.039), older age ( OR=1.17, 95% CI 1.01-1.37, P=0.043), thinner ChT ( OR=0.99, 95% CI 0.99-1.00, P=0.012), the higher the risk of optic disc tilt. The older the age, the higher the risk of developing PHOMS ( OR=1.22, 95% CI 1.06-1.40, P=0.006). Conclusions:Optic disc morphology changes may be the most common fundus alterations in children and adolescents with high myopia. The influencing factors of optic disc morphological changes (including PPA, optic disc tilt, and PHOMS) are female sex, advanced age, and ChT thinning.
