ObjectiveTo investigate the effects of jatrorrhizine on endogenous metabolites and metabolic pathways in the mouse model of ulcerative colitis. MethodsThirty male C57BL/6J mice were randomly divided into the normal group， the model group， the low-dose and high-dose jatrorrhizine groups （0.04， 0.16 g·kg^-1）， and the mesalazine group （0.52 g·kg^-1）The mouse model of ulcerative colitis was established with 3% dextran sulfate sodium （DSS） and treated with different doses of jatrorrhizine by gavage. The changes in body weight， colon length， disease activity index （DAI）， and colonic histopathology were analyzed to evaluate the therapeutic effects of jatrorrhizine. UPLC-Q-TOF/MS was employed to determine the serum and fecal levels of metabolites in mice. Metabolomics methods were used to screen the differential metabolites， on the basis of which the potential therapeutic mechanism of jatrorrhizine on DSS-induced ulcerative colitis in mice was investigated. ResultsAfter intervention with jatrorrhizine， the model mice showed significantly decreased DAI（P<0.05，P<0.01）， recovered colon length，（P<0.05，P<0.01） and alleviated histopathology of the colon. The metabolomics study screened out 13 differential metabolites in the serum and 8 differential metabolites in the feces. The pathway enrichment analysis predicted three potential metabolic pathways： Biosynthesis of unsaturated fatty acids， phenylalanine， tyrosine and tryptophan biosynthesis， and phenylalanine metabolism. ConclusionJatrorrhizine may treat ulcerative colitis by regulating the biosynthesis and metabolism of amino acids and the synthesis of unsaturated fatty acids.

Objective: To determine the association between exposure to entertainment screen content on mobile phones and symptoms of anxiety-depression co-morbidity among college students,so as to provide evidence for mental health interventions. Methods: A baseline survey was conducted from April to May 2019. A total of 1 135 college students were selected from one university each in Shangrao City, Jiangxi Province and Hefei City, Anhui Province using cluster random sampling method. A follow up study was conducted in November 2019, resulting in 1 110 matched valid responses. Self rating questionnaires were used to assess the exposure of entertainment screen content. The Depression Anxiety Stress Scale-21(DASS-21) and the Patient Health Questionnaire-9 (PHQ-9) were used to evaluate the anxiety symptoms, depressive symptoms, and symptoms of anxiety-depression co-morbidity among college students. A multivariate binary Logistic regression model was constructed following initial intergroup comparisons with Chi-square test to determine the association between baseline exposure to mobile entertainment screen content and the risk of symptoms of anxiety depression co-morbidity at baseline and the 6 month follow up. Results: The prevalence rates of symptoms of anxiety-depression co-morbidity among college students were 25.4% and 20.6% at baseline and follow up, respectively.After adjusting for confounding factors such as gender, self rated family economic status and self rated health status, the results of multivariate binary Logistic regression analysis showed that compared with the appropriate exposure level group, the exposure of entertainment screen content on mobile phones at baseline, including frequent exposure to reading( OR =1.65,95% CI =1.14-2.39), occasional exposure to other entertainment screen content ( OR =1.46,95% CI =1.01-2.10)and frequent exposure to other entertainment screen content( OR =1.76,95% CI =1.20-2.60), increased the co-occurrence risk of symptoms of anxiety-depression co-morbidity among college students during the follow up period (all P <0.05). Conclusion Occasional or frequert exposure to mobile entertainment screen content can increase the risk of symptoms of anxiety depression co-morbidity among college students.

OBJECTIVE To investigate the effect and mechanism of modified Lichong decoction （MLCD） on the apoptosis of transplanted tumor cells in nude mice. METHODS Human gastric cancer AGS cells were cultured， and a nude mice transplanted tumor model was established. The nude mice were divided into the model group and MLCD low-， medium- and high-dose groups （150， 300， 600 mg/kg）. They were given distilled water or the corresponding drug solution by gavage once daily for four consecutive weeks. The size of transplanted tumors in nude mice was measured every six days， and the tumor volume was calculated. After the medication， the nude mice were sacrificed， and the transplanted tumor tissues were isolated. The contents of lactate dehydrogenase （LDH） and reactive oxygen species （ROS） in the transplanted tumor tissues were detected， and the changes in mitochondrial membrane potential were assessed. The pathological morphological changes were observed. The enzymatic activities of caspase-3， caspase-8， and caspase-9， as well as protein expressions of Fas and FasL and mRNA expressions of caspase-3， caspase-8， caspase-9， Fas and FasL in the transplanted tumor tissues， were detected. RESULTS Compared with the model group， the volume of transplanted tumors in nude mice from all MLCD dose groups was reduced to varying degrees. The contents of LDH and ROS， as well as the enzymatic activities of caspase-3， caspase-8 and caspase-9， were significantly increased/enhanced. The mitochondrial membrane potential was significantly decreased. The protein expressions of Fas and FasL， and the mRNA expressions of caspase-3， caspase-8， caspase-9， Fas and FasL were significantly up-regulated. Most of these differences were statistically significant （ P ＜0.05 or P ＜0.01）. Pathological results showed that with increasing doses of MLCD， the cellular density in the transplanted tumor tissues gradually decreased， and typical morphological features of apoptosis， such as loosening and increasing fragmentation， became more prominent. CONCLUSIONS MLCD can induce apoptosis in transplanted tumor cells of nude mice， and its mechanism may be related to the activation of the Fas/FasL pathway and the caspase apoptotic pathway.

Objective: To investigate the association between screening detected myopia in primary school students and mixed exposure to air pollutants, so as to provide a scientific basis for the prevention and control of myopia in children and adolescents. Methods: From May to July 2023, a cluster random sampling method was used to select 15 102 primary school students in grades 3 through 6 from Hefei, Zhongshan, Shenyang, and Nanchang citys. Data were collected through questionnaires, distance vision screening, and computerized refraction. Monthly average concentration data for particulate matter (PM 10 ), fine particulate matter (PM 2. 5), NO 2 and SO 2 were used to calculate the annual average pollutant concentrations for primary school students. Quantile g computation model was employed to analyze the association between mixed exposure to air pollutants and screening detected myopia. Results: The differences in concentrations of the four pollutants among cities were statistically significant ( H =12 886.0, 13 285.0, 8 559.0, 13 181.0, all P <0.01). In the overall sample, there was no statistically significant association between combined exposure to air pollutants and the risk of myopia ( β=0.033, 95%CI=-0.004-0.072, P =0.08). Stratified analysis by outdoor activity time showed that among primary school students with outdoor activity time ≤1 h/d, mixed exposure to air pollutants was positively associated with the risk of myopia ( β=0.050, 95%CI=0.002-0.099, P =0.04); after stratification by city, combined exposure to air pollutants was significantly associated with the risk of myopia among primary school students in Nanchang and Shenyang [ β (95% CI )= 0.232(0.175-0.289), 0.080(0.006-0.155), both P <0.05], whereas no statistically significant association was observed among primary school students in Hefei and Zhongshan [ β (95% CI )=-0.010(-0.071-0.051), -0.032(-0.167-0.102), both P ＞ 0.05 ]. Conclusions Exposure to multiple air pollutants may increase the risk of myopia in primary school students, with the risk influenced by time spent outdoors and geographical location. It is recommended that outdoor activity management for children be strengthened in areas with higher air pollution levels, and that environmental factors be incorporated into comprehensive myopia prevention and control strategies.

ObjectiveTo systematically investigate the discrepancies between employment preferences and actual job placements among postgraduate students in rehabilitation medicine, explore the influencing factors, and elucidate the underlying mechanisms of their employment decisions. MethodsA cross-sectional questionnaire survey was conducted among 100 full-time postgraduate students who had graduated from Capital Medical University School of Rehabilitation in the past six years. A self-designed questionnaire was used to collect information on personal background, self-assessed competencies, employment preferences, and actual job placements. Logistic regression models were employed to analyze the factors influencing employment preferences and actual job placements, respectively. ResultsEmployment preferences among rehabilitation medicine postgraduates were highly concentrated on large tertiary hospitals (79.0%), yet the actual placement rate (61.0%) showed a significant gap. Preference for tertiary hospitals showed no significant association with individual factors such as gender, degree type or self-assessed competencies (P > 0.05). Univariate analysis revealed that those who entered tertiary hospitals scored significantly higher in self-assessed clinical skills, research ability, communication and coordination, and resource integration (|t| > 3.661, P < 0.001), and demonstrated clearer career planning (P = 0.012). Multivariate logistic regression analysis did not identify any independent predictors of actual employment within the context of this study sample (P > 0.05). ConclusionEmployment among rehabilitation medicine postgraduates is characterized by highly homogeneous preferences coexisting with complexity of factors influencing actual employment. It is recommended to optimize the training system, deepen personalized career education, and establish diversified employment guidance mechanisms to promote rational talent flow and facilitate the balanced development of the rehabilitation medical service system.

Objective: To investigate the longitudinal association between biological rhythm trajectories and the risk of anxiety, depression, and comorbid symptoms among college students, so as to provide a cumulative empirical basis for early psychiatric tracking and mental health warning systems. Methods: Using random cluster sampling method, a baseline survey was conducted from April to May 2019. One comprehensive university and one medical university were selected in Shangrao City, Jiangxi Province, and Hefei City, Anhui Province, respectively. A total of 1 029 first year college students were recruited as study participants, and four waves of longitudinal follow up were carried out over a period of two years. The Self rating of Biological Rhythm Disorder for Adolescents was used to assess college students biological rhythms, and using the dynamic data from the first two follow ups to construct the trajectory of biological rhythm changes. Mental health outcomes (anxiety and depressive symptoms) at the end of the follow up period were assessed using Generalized Anxiety Disorder-7 and Patient Health Questionnaire-9. Multivariable Logistic regression models were employed to evaluate the independent predictive value of distinct lifestyle rhythm trajectories on the detection risk of long term anxiety, depression, and their comorbid symptoms. Results: The prevalence rates of anxiety, depression, and comorbid symptoms among participants were 23.5%, 22.6%, and 16.7%, respectively. Multivariable Logistic regression analysis showed that, after adjusting for confounding factors such as sex, major, smoking, and alcohol consumption, compared with the persistent low risk reference group of overall biological rhythm, the persistent high risk trajectory group of overall assessment had an increased risk of anxiety symptoms( OR=3.87, 95%CI =2.45-6.11), depressive symptoms( OR=3.18, 95%CI =1.98-5.10), and comorbid symptoms( OR=2.43, 95%CI =1.46-4.04)(all P ＜0.05).Among college students in the elevated overall assessment risk group, the risks of anxiety symptoms ( OR=1.97, 95%CI =1.22-3.17), depressive symptoms ( OR=2.13, 95%CI =1.33-3.42), and comorbid symptoms ( OR=1.81, 95%CI =1.07-3.06) were also increased (all P < 0. 05), and the various risks in the group with increased risks were also higher than those in the group with consistently low risks. Conclusions The dynamic deterioration and persistent disruption of college students lifestyle and behavioral rhythms serve as strong early warning indicators for long term anxiety and depressive symptoms. Mental health screening in colleges and universities should incorporate multi timepoint dynamic tracking of behavioral rhythms, and circadian rhythm regulation should be regarded as a core target for group level mental health interventions.

Modern cataract surgery has completely moved beyond the traditional vision-restoring model and has fully entered a new era of refractive cataract surgery(RCS)centered on precise refractive correction. Its core objective is to provide patients with personalized visual experiences characterized by full-range, clear, and comfortable vision. Currently, although diagnostic and therapeutic technologies for RCS are rapidly evolving, there remain many bottlenecks in the precise management of the entire perioperative process that urgently need to be addressed. Preoperatively, the measurement consistency among ocular biometry devices based on different detection principles remains poor, and systematic measurement errors cannot be completely eliminated. Moreover, the individualized selection of intraocular lenses(IOLs)relies heavily on surgeons' clinical experience, lacking a standardized quantitative decision-making framework, which makes it difficult to achieve precise personalized matching. Intraoperatively, the quality of continuous curvilinear capsulorhexis is affected by multiple factors such as ocular anatomical characteristics and surgical proficiency, and its stability cannot be reliably ensured. Various intelligent surgical navigation systems are compromised by intraoperative ocular conditions, and their clinical performance fails to meet theoretical expectations. At the postoperative stage, existing IOL optical designs and materials have inherent limitations. The longterm prevention and control of posterior capsule opacification(PCO)remains a core factor restricting patients' long-term high-quality visual outcomes. This article systematically reviews the precise diagnostic and therapeutic challenges and core bottlenecks across the preoperative, intraoperative, and postoperative stages of RCS. It further explores frontier technological directions—including cross-device error compensation models, artificial intelligence-assisted decision-making, preoperative VR-based visual simulation, and the construction of intelligent surgical ecosystem platforms—to delineate targeted solutions and optimization pathways. This review aims to provide references and insights for the standardized clinical implementation, technological innovation, and future research endeavors in precision diagnosis and treatment of RCS.

Objective:To explore the impact of childhood trauma on drug relapse tendency, as well as the mediating role of post-traumatic stress disorder (PTSD).Methods:From March to May 2017, a total of 403 compulsory drug rehabilitation personnel were selected for a cross-sectional study and then were investigated by the general demography scale, drug relapse risk scale, childhood trauma questionnaire (CTQ), and PTSD checklist for DSM-5(PCL-5).SPSS 27.0 software and PROCESS 4.1 macro program were used for correlation analysis, regression analysis and Bootstrap-based mediation analysis.Results:The scores of negative emotions subscale of drug relapse risk scale, emotional abuse and emotional neglect subscales of CTQ had no significant gender differences(all P>0.05).There were gender differences in relapse tendency, childhood trauma, and PTSD total scores as well as other dimensions ( t/ Z=2.08-4.67, all P<0.05).There were pairwise positive correlations among the total score of the drug relapse risk scale(31.68±9.79), CTQ(39.90±12.13), and PCL-5(11(3, 24)) for compulsory isolation and rehabilitation personnel ( r=0.28, 0.36, 0.37, P<0.05).After controlling for gender, childhood trauma could significantly and positively predict drug relapse tendency( β=0.34, t=7.24, P<0.01), and PTSD played a mediating role between childhood trauma and drug relapse tendency, with the indirect effect of 0.11(95% CI=0.06-0.16). Conclusion:Childhood trauma can affect drug relapse tendency directly, and indirectly through PTSD.

Objective To explore the effects and mechanisms of Changpu Yujin Tang(CPYJT)on the NOD-like receptor thermal protein domain associated protein 3/cysteinyl aspartate specific proteinase-1/Gasdermin D(NLRP3/Caspase-1/GSDMD)signaling pathway-mediated neuroinflammation in rats with Tourette syndrome(TS).Methods SPF-grade male SD rats were randomly divided into the Control and TS groups.After successful modeling in the TS group,the rats were randomly divided into the Model,Tiapride,and CPYJT groups,and were treated with the corresponding drugs for 4 weeks.After the treatment,the rats' behavior was scored,H & E staining was used to observe pathological changes in the striatum,ELISA was used to measure the content of IL-1β and IL-18,RT-qPCR was used to detect the expression of NLRP3 and ASC mRNA,and Western blot was used to detect the expression of NLRP3,ASC,Caspase-1,Cleaved-Caspase-1,GSDMD,and GSDMD-NT proteins.Results Compared with the Control group,the Model group showed increased scores of stereotyped and motor behaviors(P＜0.01),pathological changes in the striatal tissue,increased content of IL-1β and IL-18(P＜0.01),and upregulated expression of NLRP3,ASC mRNA,and NLRP3,ASC,Caspase-1,Cleaved-Caspase-1,GSDMD,and GSDMD-NT proteins(P＜0.01).Compared with the Model group,the Tiapride group and the CPYJT group showed decreased scores of stereotyped and motor behaviors(P＜0.01),improved pathological damage in the striatal tissue,reduced content of IL-1β and IL-18(P＜0.01),and inhibited expression of NLRP3,ASC mRNA,and NLRP3,ASC,Caspase-1,Cleaved-Caspase-1,GSDMD,and GSDMD-NT proteins(P＜0.01).Conclusion The therapeutic effect of CPYJT on TS is related to the inhibition of the neuroinflammatory response mediated by the NLRP3/Caspase-1/GSDMD signaling pathway.

Objective To analyze the clinical characteristics and prognostic risk factors of patients with atrial fibrillation(AF)related to septic shock admitted to the intensive care unit(ICU).Methods This retrospective cohort study included 152 patients with septic shock who were admitted to the ICU between January 2020 and December 2023.Patients were categorized into AF(n=48)and non-AF(n=104)groups based on the occurrence of AF.Clinical parameters were compared between the two groups,and variables with statistically significant differences(P<0.05)were entered into a multivariate logistic regression analysis to identify clinical features associated with AF.Patients were also stratified into survival(n=103)and death(n=49)groups based on 28-day outcomes.Variables showing signifi-cant intergroup differences(P<0.05)were further included in a multivariate model to identify independent risk factors for mortality.Kaplan-Meier survival analysis was performed using AF as a binary variable,and log-rank tests were applied to compare survival curves.Results The incidence of AF was 31.58%among patients with septic shock.Compared with the non-AF group,the AF group was older,received higher cumulative doses of vasoactive agents,and had elevated levels of lactate(Lac),N-terminal brain natriuretic peptide precursor(NT-proBNP),troponin I(cTnI),tumor necrosis factorα(TNF-α),and C-reactive protein(CRP).The AF group also had higher E/e'ratios,left ventricular ejection fraction(LVEF),Acute Physiology and Chronic Health Evaluation-Ⅱ(APACHEⅡ)scores,Sequen-tial Organ Failure Assessment(SOFA)scores,and 28-day mortality rates(all P<0.05).Multivariate logistic regression identified age(odds ratio[OR]=1.060,P=0.015),SOFA score(OR=1.525,P=0.001),TNF-α(OR=1.009,P=0.026),CRP(OR=1.008,P=0.002),and E/e'(OR=1.363,P=0.023)as independent risk factors for AF.The 28-day mortality rate was 32.24%.Compared with survivors,non-survivors had significantly higher Lac,cTnI,E/e',LVEF,and TNF-α levels,higher APACHEⅡand SOFA scores,longer ICU stays,and a higher incidence of AF(all P<0.05).Multivariate analysis identified SOFA score,cTnI,E/e',and AF as independent predictors of 28-day mortality.Kaplan-Meier analysis revealed significantly poorer survival in patients with AF(χ2=6.747,P=0.009).Conclusion AF is common in ICU patients with septic shock.Advanced age,greater organ dysfunction,elevated inflammatory markers,and diastolic dysfunction are associated with AF occurrence.Organ dysfunction,myocardial injury,diastolic dysfunction,and AF are inde-pendent predictors of mortality in this population.Greater clinical attention is warranted in patients with AF and septic shock due to their elevated risk of poor outcomes.
