The c-Jun N-terminal kinase （JNK） signaling pathway， a key member of the mitogen-activated protein kinase （MAPK） family， plays a central role in the pathogenesis and progression of central nervous system （CNS） diseases by regulating core biological processes such as apoptosis， inflammatory responses， synaptic plasticity， and autophagy. This article sorts out and analyzes relevant literature published domestically and internationally in recent years， summarizing the mechanisms of action of the JNK signaling pathway in common CNS diseases and the research progress in traditional Chinese medicine （TCM） interventions in CNS diseases through the regulation of the JNK signaling pathway. Studies have shown that active components of TCM， such as berberine， paeoniflorin， and astragaloside Ⅳ， as well as compound formulations like Heixiaoyao san， Ditan tang， and Buyang huanwu tang， can exert neuroprotective effects in various CNS disorders， including Alzheimer’s disease， Parkinson’s disease， cerebral ischemia-reperfusion injury， and epilepsy， by inhibiting the aberrant activation of the JNK signaling pathway， thereby alleviating neuroinflammation， oxidative stress， and neuronal apoptosis， while improving synaptic function and cognitive behavioral deficits， regulating autophagy， and maintaining blood-brain barrier integrity.

AIM: To investigate the differences in morphological structure and retinal blood perfusion between the affected eye and the contralateral healthy eye using optical coherence tomography angiography(OCTA)in patients with idiopathic macular epiretinal membrane(IMEM)before and after surgery, and to evaluate the association of these parameters with functional and anatomical outcomes to inform prognostic assessment. METHODS:A prospective study was conducted at Zhejiang Provincial People's Hospital between January 2023 and December 2024. Consecutive patients diagnosed with unilateral IMEM were enrolled; the fellow eye served as an internal control. All participants underwent standardized ophthalmic evaluations, including optical coherence tomography(OCT), OCTA, and color fundus photography. Key quantitative parameters assessed included best-corrected visual acuity(BCVA), central macular thickness(CMT), foveal avascular zone(FAZ)area, vessel density in the inner capillary plexus(ICP), superficial capillary plexus(SCP), deep capillary plexus(DCP), and choroidal capillary perfusion area(CCPA). Measurements were obtained preoperatively and at 1 and 3 mo postoperatively. Correlation analyses were performed between the above parameters and postoperative BCVA and CMT.RESULTS: This study enrolled 30 patients(60 eyes)diagnosed with IMEM, comprising 14 males and 16 females, with a mean age of 65.4±10.8 y.At baseline, IMEM-affected eyes demonstrated significantly reduced BCVA, DCP density, and FAZ area, alongside significantly increased CMT and CCPA, compared with contralateral controls. Following vitrectomy with membrane peeling, CMT decreased significantly at both 1 and 3 mo(both P<0.05)postoperatively; DCP density and BCVA showed significant improvement(both P<0.05). No significant change in FAZ area was observed postoperatively(P>0.05). At 3 mo postoperatively, BCVA of the affected eye was negatively correlated with CMT(r=-0.549, P=0.022). At 1 mo postoperatively, CMT was negatively correlated with preoperative DCP and FAZ, positively correlated with preoperative CMT, and positively correlated with ICP and SCP at 1 mo postoperatively, and negatively correlated with FAZ at 1 mo postoperatively(all P<0.05). Furthermore, CMT at 3 mo postoperatively was negatively correlated with preoperative DCP(r=-0.498,P=0.042).CONCLUSION:In patients with IMEM, the affected eyes exhibit significantly reduced DCP density and FAZ area, alongside increased CMT and CCPA. Following vitrectomy with membrane peeling, CMT decreased progressively, DCP density demonstrated partial restoration, and vision improved gradually. Preoperatively, smaller CMT larger DCP, and FAZ were associated with more favorable surgical outcomes; postoperatively, smaller ICP and SCP densities—combined with a larger FAZ—also correlated with better functional recovery.

Objective To understand the current situation of nutrition literacy of primary and secondary school students in Shijingshan District of Beijing, and analyze its influencing factors, and to put forward targeted suggestions for improving the students’ nutrition literacy and promoting their healthy growth. Methods A multi-stage stratified cluster sampling method was used to select 2480 primary and secondary school students and their parents from 5 primary schools, 3 middle schools and 1 high school in Shijingshan District. The multivariate logistic regression model was used to analyze the factors influencing the attainment rate of nutrition literacy. Results The median score of nutrition literacy of 2480 primary and secondary school students from grades 1 to 12 was 77.86 (in hundred-mark system), the quartile range (IQR) was 16.96, and the attainment rate of nutrition literacy was 42.46%. The cognitive level (45.12%) was higher than the skill level (41.20%) among students from grades 3 to 12. In terms of skills, the attainment rate of food preparation was the lowest, at 30.38%. The scores of nutrition literacy of girls were higher than those of boys, and the scores of primary school students were higher than those of secondary school students. Students with different levels of caregiver’s education, family income, and family food environment had different scores of nutrition literacy, and the differences were statistically significant (P<0.05). Multivariate logistic regression analysis showed that the attainment rate of nutrition literacy was closely related to student’s gender and study stage, caregiver’s education level, and family food environment. Conclusion The nutrition literacy of primary and secondary school students in Shijingshan District still needs to be improved, especially in the aspect of skills. Targeted nutrition education should be carried out.

Objective: To analyze the current status and influencing factors of psychological crisis among college students, so as to provide a scientific basis for the formulation of psychological crisis intervention plans in colleges and universities. Methods: From September to December 2024, 645 college students from a medical undergraduate university in Heilongjiang Province were selected with a convenience sampling method. A convergent mixed analysis design was used. Quantitative analysis was conducted using College Students Psychological Crisis Screening Scale, Emotion Regulation Questionnaire, Short-Egna Minnen av Barndoms Uppfostran and Perceived School Climate Scale. Binary Logistic regression analysis was used to explore the related factors of psychological crisis among college students. Qualitative research was conducted on 15 college students with psychological crisis identified in the quantitative analysis by a purposive sampling method. The interview data were organized and analyzed using the thematic framework analysis method. Results: Among the surveyed college students, 92 (14.3%) had psychological crisis. Binary Logistic regression analysis results showed that positive parenting style ( OR=0.97,95%CI =0.95-0.99), negative parenting style ( OR=1.01,95%CI =1.00-1.02), cognitive reappraisal ( OR=0.88, 95%CI =0.83-0.92), expressive suppression ( OR=1.08, 95%CI =1.02-1.15), and perceived campus atmosphere ( OR=0.97, 95%CI =0.95-0.98) were all related factors of psychological crisis among college students ( P <0.05). The qualitative analysis results showed that there were three themes for the influencing factors of college students psychological crisis, including differential impact of emotion regulation strategies on psychological state, shaping of psychological state of college students by family and bidirectional effect of perceived campus atmosphere on psychological state. Mixed analysis results showed that the influencing factors of college students psychological crisis were consistent in terms of emotion regulation strategies, and were expansive in terms of parenting style and perceived campus atmosphere. Conclusion Schools and mental health service departments can reduce the risk of psychological crisis by optimizing cognitive reappraisal and reducing expressive suppression, improve the level of psychological crisis by strengthening positive family interaction and blocking negative parenting style, and maintain the mental health level of college students by building a supportive campus environment and alleviating high pressure.

ObjectiveCardiovascular diseases pose a major public health challenge in China. The burden of cardiovascular disease associated with high low-density lipoprotein cholesterol （LDL-C） has increased steadily nationwide. A comprehensive analysis of secular trends in cardiovascular disease burden and its determinants is crucial for developing targeted interventions and evidence-based health policies. MethodsBased on data from the Global Burden of Disease Study 2021， we analyzed the trends in deaths， disability-adjusted life years （DALYs）， age-standardized mortality rates （ASMR）， and age-standardized DALY rates （ASDR） of cardiovascular diseases attributable to high LDL-C in China from 1990 to 2021 using Joinpoint regression analysis. An age-period-cohort model was applied to assess the contributions of age， period， and cohort effects to changes in the cardiovascular disease burden attributable to high LDL-C. Projections of the high LDL-C-attributable cardiovascular disease burden in China from 2022 to 2030 were generated using a Bayesian age-period-cohort model. ResultsBetween 1990 and 2021， China saw a substantial rise in both deaths and disability-adjusted life years （DALYs） from cardiovascular disease linked to high LDL-C. Joinpoint regression revealed key turning points in this trend： an overall increase continued until 2004， after which the burden began to fall starting in 2011. Throughout this period， age-standardized mortality and DALY rates were consistently higher in males than in females. Age-period-cohort analysis further indicated that mortality and DALY rates due to high LDL-C increased almost exponentially with age， while period and cohort risks generally decreased over time. Projections suggest a continued decline in age-standardized mortality rates from LDL-C-related cardiovascular disease for both Chinese men and women by 2030. ConclusionRapid population growth and accelerated ageing in China emerge as primary drivers of the escalating cardiovascular diseases burden linked to elevated LDL-C. The burden of cardiovascular diseases is higher in men compared to women. By 2030， the burden of cardiovascular disease caused by high LDL-C in China will remain severe. These findings underscore the critical need for gender-specific screening protocols， age-tailored interventions， and personalized management frameworks to mitigate this public health challenge.

Objective To investigate the causal relationship between gut microbiota and diffuse large B-cell lymphoma(DLBCL).Methods Employed a two-sample bidirectional Mendelian randomization approach,using summary statistics from genome-wide association studies(GWAS)to extract single nucleotide polymor-phisms(SNPs)associated with exposure and outcome as instrumental variables.Exposure instrumental varia-bles(P＜1×10-5)and outcome instrumental variables(P＜5×10-8)were selected based on the P-values of SNPs.Three different Mendelian randomization methods were used to analyze the relationship between gut microbiota and DLBCL,with sensitivity analyses including heterogeneity,pleiotropy,and leave-one-out tests.Results Bilophila(OR=2.043,95%CI:1.279-3.264),Coprobacter(OR=1.371,95%CI:1.035-1.816),Eubacterium eligens group(OR=1.996,95%CI:1.291-3.087)increased the risk of DLBCL.Alistipes(OR=0.588,95%CI:0.359-0.963),Eubacterium eligens group(OR=1.996,95%CI:1.291-3.087),Slackia(OR=0.688,95%CI:0.479-0.988)reduced the risk of DLBCL.Reverse Mendelian randomization a-nalysis failed to reveal any evidence of a causal relationship between DLBCL and the six gut microbiota.Con-clusion There is a causal association between gut microbiota and DLBCL.

OBJECTIVE: To assess the association of single nucleotide polymorphisms (SNPs) of interleukin-23 receptor (IL-23R) gene with susceptibility to psoriasis. METHODS: Two hundred and ten psoriasis patients admitted to Xinxiang Central Hospital from January 2019 to December 2024 were selected as the study group, and 210 healthy individuals undergoing physical examination during the same period were selected as the control group. 3 mL of peripheral venous blood sample was collected from each individual from the two groups, and PCR-Restriction fragment length polymorphism (PCR-RFLP) assay was used to determine the polymorphisms of the IL-23R gene at rs2201841, rs1004819, rs10889677, rs1343151 and rs1495965 loci. Genotypic and allelic distribution of each SNP locus was calculated to assess the association between SNPs of the IL-23R gene with the onset of psoriasis, and the difference in serum IL-23 levels among patients with different genotypes at each locus was compared. This study was approved by the Medical Ethics Committee of Xinxiang Central Hospital (Ethic No. 2024-749). RESULTS: The results showed that the frequency of CC genotype at rs1004819 locus of the study group was significantly higher than that of the control group (26.19% vs. 18.10%, P < 0.05), and the frequency of C allele was also significantly higher than that of the control group (54.05% vs. 42.62%, P < 0.05). There was no significant difference in allelic and genotypic frequencies between the two groups at rs2201841, rs10889677, rs1343151, and rs1495965 loci (P > 0.05). The dominant and recessive inheritance patterns at the rs1004819 locus are associated with susceptibility to psoriasis (P < 0.05), while the different inheritance patterns at rs2201841, rs10889677, rs1343151, and rs1495965 loci are not associated with psoriasis (P > 0.05). The serum IL-23 levels of patients with CC genotype at the rs1004819 locus were higher than those with the CT and TT genotypes (P < 0.05). No significant difference was detected in the serum levels of IL-23 between patients with different genotypes for the rs2201841, rs10889677, rs1343151, and rs1495965 loci (P > 0.05). CONCLUSION The polymorphism at the rs1004819 locus of the IL-23R gene is associated with susceptibility to psoriasis, and individuals carrying the CC genotype and C allele have a higher risk of developing the disease.

ObjectiveThe lung mesenchymal stem cells （LMSCs） induced by D-galactose （D-gal） were intervened by Wenfei Huaxian decoction-containing serum to explore the mechanism of Wenfei Huaxian decoction in delaying the senescence of LMSCs through the nicotinamide phosphoribosyltransferase/silent information regulator 1 （NAMPT/SIRT1） signaling pathway. MethodWenfei Huaxian decoction-containing serum was prepared. LMSCs were isolated by gradient density centrifugation， and they were cultured and identified in vitro. The senescence model in vitro was established by stimulating cells via D-gal for 24 h. LMSCs cells were modeled after being treated with different volume fractions （5%， 10%， 20%， 40%， and 80%） of Wenfei Huaxian decoction-containing serum for 24 h， and the cell proliferation level was detected by methyl thiazolyl tetrazolium （MTT） method. The cells were randomly divided into blank serum group， model group， and high， medium， and low dose groups of Wenfei Huaxian decoction-containing serum. Senescence-associated β-galactosidase （SA-β-gal） staining was used to detect the senescence of LMSCs in each group. The content of NAD + was detected by colorimetry. The levels of senescence-associated factors （p16 and p53）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） in cell culture supernatant were detected by enzyme-linked immunosorbent assay （ELISA）. Western blot was used to detect the relative expression of senescence-associated proteins and NAMPT/SIRT1 signaling pathway-related proteins. ResultCompared with the blank serum group， the proliferation of LMSCs was significantly inhibited after D-gal stimulation for 24 h （P<0.01）. Compared with the model group， the proliferation of LMSCs could be promoted after intervention with the corresponding Wenfei Huaxian decoction-containing serum （P<0.05， P<0.01）. Compared with the blank serum group， the SA-β-gal staining of LMSCs in the model group after D-gal stimulation was enhanced， and the content of NAD⁺ was increased （P<0.01）. The expression levels of senescence factors p16 and p53， as well as SASP pro-inflammatory factors IL-6 and TNF-α in the cell culture supernatant， were significantly increased （P<0.01）. The expression of senescence-associated proteins p16， p21， and p53 increased （P<0.01）， and the protein expression of NAMPT， SIRT1， peroxisome proliferator-activated receptor γ coactivator 1α （PGC-1α）， and forkhead box family transcription factor O1 （FoxO1） decreased （P<0.01）. Compared with the model group， the SA-β-gal staining of LMSCs in each group of Wenfei Huaxian decoction-containing serum was significantly reduced， and the content of NAD⁺ was decreased （P<0.01）. The senescence factors （p16 and p53） and inflammatory factors （IL-6 and TNF-α） in the cell culture supernatant were significantly decreased （P<0.01）. The expression of senescence-associated proteins （P16， P21， and P53） decreased （P<0.05， P<0.01）. The protein expressions of NAMPT， SIRT1， PGC-1α， and FoxO1 were significantly up-regulated （P<0.05， P<0.01）. ConclusionWenfei Huaxian decoction can alleviate senescence and inflammatory response damage of D-gal-induced LMSCs， and its mechanism may be related to the regulation of the NAMPT/SIRT1 signaling pathway.

Objective To investigate the mechanism and protective effect of Humanin(HN)on rotenone(Rot)-induced toxic damage for dopamine neurons.Methods The Rot-poisened PC12 cell model was constructed,and the control group,the Rot poisening group,the HN pretreated Rot poisening group,and the HN treatment group were set up.ELISA was used to detect the content of HN inside and outside of Rot-infected cells,CCK-8 assay was used to detect cell viability,and ATP detection kit was used to detect the intracellular ATP content.Dichloro-dihydro-fluorescein diacetate(DCFH-DA)assay was used to detect the level of reactive oxygen species(ROS)in cells.Western blotting was performed to detect the expression level of mitochondrial autophagy regulatory proteins Pink1,Parkin,p62,LC3,mitochondrial biogenesis regulatory protein PGC1α,division/fusion regulatory proteins OPA1,MFN2,DRP1,p-DRP1 and antioxidant stress regulatory proteins Keap1 and Nrf2.HBAD-mcherry-EGFP-LC3 adenovirus transfected cells was used to observed the number of autophagosomes and autophagolysosomes.Results The results showed that the intracellular concentration of HN in PC12 in the Rot poisening group was significantly higher than that in the control group(P＜0.05);Compared with the control group,the Rot poisening group had significantly decreased activity of PC12 cells,decreased ATP content and increased production of ROS.After the poisen of Rot in PC12 cells,the expression of Pink1 and p-Parkin,the ratio of LC3Ⅱ/LC3Ⅰ and the expression of p-DRP1 in mitochondrial fusion protein was increased,while the expression of p62,the expression of mitochondrial biogenesis protein PGC1 α,mitochondrial fusion proteins MFN2 and OPA1,and antioxidant stress proteins Keap1 and Nrf2 were decreased(all P＜0.05).The number of autophagosomes and autophagolysosomes in PC12 cells in the Rot poisening group was higher than that in the control group(P＜0.05),and HN pretreatment(20 μmol/L)could significantly improve the changes mentioned above caused by Rot poisening(P＜0.05).Conclusion HN ameliorates Rot-induced toxic damage for dopamine neurons by inhibiting mitophagy and mitochondrial division and promoting mitochondrial biogenesis and fusion,and anti-oxidative stress.
