Objective: To explore the impact of adverse childhood experiences (ACEs) on health risk behaviors (HRBs) among college students and the mediating role of psychological symptoms, so as to provide a basis for developing intervention strategies. Methods: From March to April 2023, a convenience cluster sample of 1 801 students from 12 universities in Nanning, Liuzhou, Guilin, Wuzhou of Guangxi completed an online survey. A self designed questionnaire, Adverse Childhood Experiences-International Questionnaire (ACE-IQ) and Symptom Checklist-90 (SCL-90) were used for evaluation tools. Binary Logistic regression, structural equation modeling (SEM) and Bootstrap methods were used to analyze the associations and mediating effects. Results: Overall, 71.2% of college students experienced at least one type of ACE, with emotional neglect (40.3%) and emotional abuse ( 25.2 %) having the highest detection rates. The top three HRBs were unhealthy diet (77.8%), physical inactivity (54.1%), and smoking/alcohol use (18.5%). Logistic regression showed that poor family functioning, abuse, and extra familial violence were each associated with an increased risk of smoking/alcohol use ( OR =1.14, 1.11, 1.18) and deliberate self harm ( OR =1.26, 1.19,1.30) (all P <0.05). Experience of abuse increased the risk of high risk sexual behavior and family dysfunction increaded the risk of physical inactivity, respectively ( OR = 1.07 , 1.04, both P <0.05). Mediation analysis revealed that anxiety ( β =0.20) and depression ( β = 0.09 ) partially mediated the pathway from poor family functioning to deliberate self harm; paranoia ( β =0.02) partially mediated the pathway from abuse to high risk sexual behavior; and obsessive-compulsive symptoms ( β =0.26) and depression ( β =0.10) partially mediated the pathway from extra familial violence to deliberate self harm (all P <0.05). Conclusion Psychological symptoms play a mediating role in the association between ACEs and HRBs, and mental health interventions may reduce the risk of HRBs among college students.

Objective To investigate the etiology and treatment of dysuria shortly after holmium laser enucleation of the prostate (HoLEP) for benign prostatic hyperplasia (BPH), so as to improve the therapeutic efficacy. Methods A retrospective analysis was conducted on 1361 BPH patients who received HoLEP at our hospital during Mar. 2018 and Mar. 2025. All patients underwent ultrasound, computed tomography (CT), urethral probing or radiography, cystourethroscopy, and urodynamic testing. The causes, treatments and prognosis of dysuria after operation were summarized. Results ninety-eight patients (7.2%) experienced dysuria within 3 months after surgery, and all patients received initial urethral dilation. Among the 62 cases with urethral stricture, 28 were treated with urethral dilation (average of 8 sessions), 16 underwent external urethral incision, 8 underwent anterior urethroplasty, and 10 underwent transurethral plasma incision for urethral stricture. Of the 12 cases with residual prostate tissue, 5 underwent urethral plasma prostatectomy and 7 received medication. All of the 12 cases with bladder neck contracture underwent transurethral plasma incision of the bladder neck and local drug injection. Five cases with intravesical blood clots underwent urethral blood clot irrigation, 2 of which developed active bleeding and then underwent electrocoagulation. Four cases with detrusor dysfunction had catheters re-indwelled for one week followed by medication. Two cases with stone and one case with tissue fragment impacted in the urethra underwent urethral holmium lithotripsy and cystoscopic removal. All patients underwent reoperation successfully and experienced complete resolution or significant improvement of urinary difficulties. Conclusion A certain proportion of patients experience dysuria after HoLEP, with diverse etiologies. The combination of prevention and treatment can reduce the incidence of dysuria.

Pancreatic cancer （PC）， a highly malignant tumor of the digestive system， is characterized by extremely high incidence and mortality rates， imposing a severe burden on the healthcare system. Despite significant advancements in comprehensive therapeutic strategies for PC， clinical benefits for patients remain limited due to the high heterogeneity and unique microenvironment of the tumor. Therefore， further elucidating the molecular mechanisms underlying PC progression and developing novel， effective therapeutic strategies have become an urgent necessity in the current research. Programmed cell death （PCD） is a genetically orchestrated process of autonomous cell demise that is crucial for maintaining cellular homeostasis. Recent studies have demonstrated that tumor cells can remodel the tumor microenvironment by modulating various PCD pathways—including apoptosis， autophagy， pyroptosis， and ferroptosis—thereby driving tumor proliferation， invasion， and drug resistance. Traditional Chinese medicine （TCM） possesses unique advantages in anti-tumor therapy， characterized by multi-component， multi-target， and multi-pathway regulation. Accumulating evidence suggests that TCM formulas and their natural active compounds can effectively delay the malignant progression of PC by modulating PCD in tumor cells. This article systematically summarizes the molecular mechanisms of PCD in PC progression and reviews the mechanisms by which TCM formulas and natural active compounds intervene in PC through PCD modulation. This review aims to provide theoretical support and future research directions for the prevention and treatment of PC with TCM.

Diabetic nephropathy belongs to diabetic microvascular aseptic inflammation， which is the main cause of end-stage renal disease and can cause damage to the structure of glomeruli and tubulointerstitium. Pyroptosis is a potent pro-inflammatory model of programmed cell death mediated by gasdermin （GSDM） protein family， which is characterized by nuclear shrinkage， chromatin DNA fragmentation， plasma membrane rupture， cell swelling and deformation. Related studies have found that pyroptosis is closely related to the occurrence and development of diabetic nephropathy. Inhibition of pyroptosis to a certain extent can reduce diabetic renal injury， so the pathway of pyroptosis involved in the pathogenesis of diabetic nephropathy is the current research focus. The characteristics of multi-components， multi-targets and multi-pathways of traditional Chinese medicine have significant advantages in the treatment of diabetic nephropathy. Some components of traditional Chinese medicine， single traditional Chinese medicine and compound prescription of traditional Chinese medicine can improve diabetic renal injury by inhibiting pyroptosis pathway and related targets. Based on the molecular mechanism of pyroptosis， this paper clarifies the mechanism of pyroptosis in diabetic nephropathy by expounding the relationship between pyroptosis and its pathway targets and diabetic nephropathy. This paper summarizes the research status of traditional Chinese medicine in the treatment of diabetic nephropathy by interfering with related pyroptosis pathways in recent years， so as to provide perspectives and ideas for the prevention， early diagnosis， drug development and molecular treatment of diabetic nephropathy in the future.

Chinese medicine therapy for removing gallstones is one of the methods for the treatment of cholelithiasis.In the view of Professor Liu Fengbin,attacking of external pathogens,improper diet and emotional disorders contribute to the main causes of cholelithiasis,and the pathogenesis of cholelithiasis is due to qi stagnation of both liver and gallbladder,and internal obstruction of damp-heat.The occurrence of cholelithiasis is closely related to deficiency of spleen and stomach,and is correlated with the pathological factors of turbid phlegm and blood stasis.For the Chinese medicine treatment of cholelithiasis,Professor Liu follows the principle of"treatment in accordance with three categories of etiological factors"(i.e,seasons,environment and body constitution).He advocates the integration of traditional Chinese medicine and western medicine,and is good at utilizing Lingnan herbs and distinctive herbs that can dissolve stones and remove stones.The treatment for cholelithiasis is mainly through the therapies of soothing liver and alleviating depression,clearing heat and removing dampness,and normalizing gallbladder function to remove stones,and is also supplemented by the therapies of invigorating spleen and replenishing qi,regulating qi to resolve phlegm,and activiting qi movement and blood circulation.Modified Da Chaihu Decoction plus Sijin Decoction is often used as a basic formula for treating cholelithiasis,which is mainly composed of Desmodii Styracifolii Herba,Galli Gigerii Endothelium Corneum,Bupleuri Radix,Curcumae Radix,Scutellariae Radix,Aucklandiae Radix,Aurantii Fructus Immaturus stir-fried with bran,Paeoniae Radix Rubra,Linderae Radix,and Rhei Radix et Rhizoma.

Objective To analyze the factors affecting the prevalence of hyperuricemia(HUA)in an island troop.Methods A total of 1 113 soldiers stationed on an island from December 2021 to December 2022 were selected as research objects by cluster sampling.Their lifestyle and health information were collected.Physical examination and laboratory detection were conducted.Multivariate logistic regression was used to analyze the influencing factors of HUA.Results The prevalence rate of HUA was 21.02%(234/1 113).There were significant differences in the body mass index(BMI),waist-to-hip ratio,triglyceride,alanine aminotransferase,and creatinine between the soldiers with hyperuricemia and the soldiers with normal blood uric acid(P<0.05).Multivariate logistic regression analysis showed that BMI≥24(OR=1.49,95%CI:1.09-2.05),abnormal liver function(OR=2.26,95%CI:1.31-3.92),and dyslipidemia(OR=1.46,95%CI:1.01-2.12)were positively correlated with hyperuricemia;age>30 years old(OR=0.59,95%CI:0.37-0.93)and exercise time>1 h per week(OR=0.46,95%CI:0.22-0.97)were negatively correlated with HUA.Conclusion The prevalence rate of hyperuricemia is at a high level in an island troop.BMI≥24,age≤30 years old,exercise time≤1 h per week,abnormal liver function,and dyslipidemia are the risk factors for HUA.Prevention and control measures should be taken as early as possible for the soldiers with these risk factors.

Objective Hypobaric chamber and simulated weightless bed are essential methods for aerospace medical research,and conducting state assessment of volunteers before and after hypobaric chamber and simulated weightless bed tests is an essential guideline for aerospace implementation medicine.To further improve the efficiency of human condition assessment,in addition to the conventional biochemical and physiological indicators,the human oral exhaled gas can be used for condition assessment,and the olfactometry acquisition equipment and analysis software can collect and detect most volatile gases to complete the human oral exhaled gas data acquisition.Conducting comparative analysis of olfactory mapping data from different populations may be a means to assess the status of the body.Methods The olfactometry acquisition equipment was used to collect the oral exhaled breath olfactometry profiles of the general population,hypobaric cabin volunteers,and ambulatory volunteers.The olfactometry analysis software was used to calculate the 12 eigenvalues of the olfactometry profiles and the t-SNE downscaling,and the radar plots were used to analyze the olfactometry profiles of the general population,low-pressure cabin volunteers,and ambulatory volunteers respectively.A comparative analysis of different populations was conducted.Results(1)The t-SNE mapping data of the general population and the ambulatory volunteers were almost indistinguishable;(2)the t-SNE mapping data of the hypobaric cabin volunteers and the general population had a slight overlap,but the distinguishability of the vast majority of the t-SNE mapping data was obvious;(3)the t-SNE mapping data of the hypobaric cabin volunteers and the ambulatory volunteers were distinguishable with no overlap,and the ambulatory t SNE data are highly aggregated,and the distribution of t-SNE data in low-pressure cabin is more discrete;(4)there are 2-3 sensors with large eigenvalues and a large range of variation for both low-pressure cabin volunteers and recumbent volunteers after training activities,and the common sensor with a large range of variation is S6.Conclusion Olfactory diagnostic analysis mapping may be a means to assess the health status of the body and may be useful for spaceflight health status assessment in the future.The analysis and application of flight health state assessment can be a reference in the future.

Objective To investigate the effect of miR-185-5p-mediated targeted negative regulation of transmembrane 9 superfamily member 1(TM9SF1)on proliferation,migration and autophagy in lung adenocarcinoma cells.Methods The expression of miR-185-5p in lung adenocarcinoma tissues was analyzed using dataset GSE51853 downloaded from the Gene Expression Omnibus(GEO)database.Potential target proteins of miR-185-5p were predicted using online databases(miRTargetLink,miRTarbase,and DIANA-microT-CD),and autophagy-related proteins were obtained from HADb.The intersected results from these four databases was identified,and survival curves of vascular endothelial growth factor A(VEGFA)and TM9SF1 within the overlapping candidates were analyzed using the StarBase database.TM9SF1 3'UTR wild-type(WT)or TM9SF1 3'UTR mutant(MUT)reporter plasmids were separately co-transfected with miR-185-5p control plasmid(CON)or miR-185-5p overexpression plasmid(over-miR-185-5p)into HEK-293T cells.A dual-luciferase reporter gene assay was employed to assess the binding interaction between miR-185-5p and TM9SF1 and quantify the subsequent luciferase activity.Western blotting was used to assess TM9SF1 protein expression levels in A549 cells transfected with over-miR-185-5p.A549 cells were divided into three groups:(1)CON+NC group,co-transfected with miR-185-5p control plasmid and TM9SF1 control plasmid;(2)over-miR-185-5p+NC group,co-transfected with over-miR-185-5p and TM9SF1 control plasmid;(3)over-miR-185-5p+over-TM9SF1 group,co-transfected with both miR-185-5p and TM9SF1 overexpression plasmids.EdU cell proliferation assay,wound healing assay,and Transwell migration assay were performed to validate the effects of miR-185-5p targeted binding to TM9SF1 on proliferation and migration capacities in lung adenocarcinoma.Changes in autophagic flux and mitochondrial membrane potential(MMP)of lung adenocarcinoma cells were detected using stubRFP-sensGFP-LC3 lentivirus and JC-1 assays,respectively.Results In the GSE51853 dataset,miR-185-5p expression level was significantly lower in lung adenocarcinoma tissues compared with normal lung tissues(P<0.01).qRT-PCR analysis revealed that miR-185-5p expression was downregulated in lung adenocarcinoma cell lines NCI-H1299 and A549 compared with normal lung epithelial cells BEAS-2B(P<0.01).Bioinformatics predictions using miRTargetLink,miRTarbase,DIANA-microT-CD,and HADb databases indicated that miR-185-5p could target and regulate the autophagy-related protein TM9SF1.Dual-luciferase reporter assays and Western blotting demonstrated that miR-185-5p directly bound to the 3'UTR region of TM9SF1 mRNA,and overexpression of miR-185-5p significantly reduced the expression of target protein TM9SF1(P<0.05).EdU cell proliferation,wound healing,and Transwell migration assays demonstrated that miR-185-5p overexpression inhibited proliferation and migration capacities of lung adenocarcinoma cells,whereas TM9SF1 overexpression could attenuate this inhibition effect(P<0.05).Results of stubRFP-sensGFP-LC3 for autophagic flux analysis demonstrated that overexpression of miR-185-5p enhanced autophagic flux in A549 cells,whereas co-overexpression of miR-185-5p and TM9SF1 suppressed autophagic flux.JC-1 assays showed a decreased MMP level in A549 cells after miR-185-5p overexpression,with higher MMP level observed when miR-185-5p and TM9SF1 were co-overexpressed.Conclusion miR-185-5p may suppress proliferation,migration,and autophagy capacities in lung adenocarcinoma cells by targeting TM9SF1 through negative regulation.
