ObjectiveTo investigate somatization symptoms in adolescents during frequent earthquakes in Hefei， and to explore their correlation with earthquake experiences. MethodsA cross-sectional survey was used to select 324 adolescents in Hefei as the survey objects. The self-rating scale of somatization symptoms （SSS） and the fatigue intensity scale （FIS） were used to evaluate the somatization symptoms and fatigue degree of middle school students， and multivariate Logistic regression analysis was used to explore the related factors of somatization symptoms and fatigue among middle school students. ResultsA total of 324 adolescents were included， and the overall detection rate of somatization symptoms was 6.5%， and the detection rate of moderate or above fatigue was 20.1%. The results of regression analysis showed that adolescents who were concerned about the earthquake for a longer time （≥1 h） had a higher risk of somatization symptoms （OR=5.430， 95%CI： 1.547-19.058）， and adolescents who received pre-earthquake training had a lower degree of fatigue （OR=0.535， 95%CI： 0.292-0.981） （P<0.05）. ConclusionDuring the frequent earthquakes， adolescents have more somatization symptoms and fatigue. Therefore， it is crucial to enhance health education， reduce the emphasis on event-related reports， and implement earthquake prevention and disaster reduction training to improve the physical and mental health of adolescents.

ObjectiveTo investigate the potential mechanism of Qingguangan Ⅱ Formula （青光安Ⅱ号方， QGAⅡ） in the treatment of glaucoma from the perspectives of oxidative stress and the cyclic adenosine monophosphate/ protein kinase A （cAMP/PKA） signaling pathway. MethodsForty SD rats were randomly assigned to a medicated serum group （n=30）， which received QGAⅡby intragastric administration at 6.741 g/（kg·d）， and a blank group （n=10）， which received normal saline at 10 ml/（kg·d）. After 7 consecutive days of administration， medicated serum and blank serum were prepared. The optimal concentration of medicated serum for R28 cell intervention was determined using CCK-8 assay. An in vitro glaucoma model was established by exposing R28 cells to continuous hydrostatic pressure combined with oxygen-glucose deprivation （OGD） for 24 h to simulate the pathological microenvironment of glaucomatous optic nerve injury. The experiment set a control group （complete medium）， model group （glucose-free medium + tri-gas incubator）， medicated serum group （selected concentration of QGA-medicated serum + glucose-free medium + tri-gas incubator）， and blank serum group （blank serum + glucose-free medium + trigas incubator）. The total culture medium volume in each culture dish was 5 ml. After 24 h of culture， cell proliferation was assessed using the EdU immunofluorescence assay， and apoptosis was determined by flow cytometry. Malondialdehyde （MDA） content and superoxide dismutase （SOD） activity were measured using biochemical assays. Western Blotting was performed to detect the expression of oxidative stress-related proteins including 4-hydroxynonenal （4-HNE） and heme oxygenase-1 （HO-1）， apoptosis-related proteins including B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， and cleaved caspase-3 （C-caspase-3）， and cAMP/PKA signaling pathway-related proteins including protein kinase A （PKA）， phosphorylated PKA （p-PKA）， cAMP response element-binding protein （CREB）， and phosphorylated CREB （p-CREB）. Intracellular cyclic adenosine monophosphate （cAMP） levels were determined by ELISA. In addition， a forskolin （agonist） group， an H89 （inhibitor） group， and a 7.5% medicated serum plus inhibitor group were established to further investigate the effects of QGAⅡ-medicated serum on oxidative stress and the cAMP/PKA signaling pathway in R28 cells. ResultsA concentration of 7.5% QGAⅡ-medicated serum was identified as the optimal concentration for subsequent experiments. Compared to the control group， the model group exhibited significantly decreased cell proliferation， SOD activity， Bcl-2 protein expression， p-PKA/PKA ratio， p-CREB/CREB ratio， and cAMP content， as well as increased apoptosis rate， MDA content， and the protein expression levels of 4-HNE， HO-1， Bax， and C-caspase-3 （P＜0.01）. Compared to the model group， the 7.5% medicated serum group showed significant improvements in all of the above parameters （P＜0.01）. In the forskolin group， the apoptosis rate and the expression levels of C-caspase-3 and Bax significantly decreased， whereas Bcl-2 expression and the p-PKA/PKA and p-CREB/CREB ratios increased compared to those in the model group （P＜0.01）. Compared to the 7.5% medicated serum group， the 7.5% medicated serum plus inhibitor group exhibited significantly increased expression of C-caspase-3 and Bax， together with significantly decreased Bcl-2 expression and reduced p-PKA/PKA and p-CREB/CREB ratios （P＜0.01）. ConclusionUnder continuous hydrostatic pressure and OGD-induced injury conditions， QGAⅡ- containing serum effectively mitigates oxidative stress in R28 cells， activates the cAMP/PKA signaling pathway， and inhibits apoptosis， thereby exerting a neuroprotective effect on retinal ganglion cells

Chronic post-dissection aortic aneurysms (PDAAs) are severe long-term complications following surgical or medical conservative management of aortic dissection, primarily caused by persistent perfusion of the residual false lumen. The persistent patency of the residual false lumen is the key pathological mechanism leading to adverse distal aortic remodeling, which can result in progressive aortic dilation, increased risk of rupture, and elevated reintervention requirements, significantly affecting patients' long-term prognosis. This article reviews the latest research progress on assessment methods, influencing factors, and intervention strategies for distal aortic remodeling in PDAAs, aiming to provide reference for clinical decision-making.

OBJECTIVE: Circadian rhythm disruption (CRD) is a risk factor that correlates with poor prognosis across multiple tumor types, including hepatocellular carcinoma (HCC). However, its mechanism remains unclear. This study aimed to define HCC subtypes based on CRD and explore their individual heterogeneity. METHODS: To quantify CRD, the HCC CRD score (HCCcrds) was developed. Using machine learning algorithms, we identified CRD module genes and defined CRD-related HCC subtypes in The Cancer Genome Atlas liver HCC cohort (n = 369), and the robustness of this method was validated. Furthermore, we used bioinformatics tools to investigate the cellular heterogeneity across these CRD subtypes. RESULTS: We defined three distinct HCC subtypes that exhibit significant heterogeneity in prognosis. The CRD-related subtype with high HCCcrds was significantly correlated with worse prognosis, higher pathological grade, and advanced clinical stages, while the CRD-related subtype with low HCCcrds had better clinical outcomes. We also identified novel biomarkers for each subtype, such as nicotinamide n-methyltransferase and myristoylated alanine-rich protein kinase C substrate-like 1. CONCLUSION We classify the HCC patients into three distinct groups based on circadian rhythm and identify their specific biomarkers. Within these groups greater HCCcrds was associated with worse prognosis. This approach has the potential to improve prediction of an individual's prognosis, guide precision treatments, and assist clinical decision making for HCC patients.

Objective To investigate the value of repeat renal biopsy in the treatment and prognosis of nephrotic syndrome(NS)and acute kidney injury(AKI)following immunosuppressive therapy in patients with lupus nephritis(LN). Methods A retrospective analysis was conducted for the clinicopathological data and follow-up records of LN patients undergoing repeat renal biopsy at Peking Union Medical College Hospital from January 1,2009 to December 31,2021. Results A total of 76 patients(55 females,72.4%)were included in this study,with the mean age at the first biopsy being(29.0±10.4)years,the median inter-biopsy interval of 4.0(2.0,7.0) years,and the median total follow-up duration of 7.5(5.0,13.8)years.Pathological transformation occurred in 46(60.5%)patients,and 2 patients had comorbid diabetic nephropathy.At repeat renal biopsy,50(65.8%) patients presented NS.These patients demonstrated lower estimated glomerular filtration rate(eGFR)(P<0.001),higher chronicity index(CI)(P=0.029),and higher complement C3(P<0.001)and C4(P<0.001)levels than those with NS at the first renal biopsy(n=50).Among the 28(36.8%) patients with AKI at repeat renal biopsy,8(28.6%)experienced acute exacerbation of chronic renal insufficiency.These patients exhibited higher serum creatinine level(P=0.002),C4 level(P=0.033),CI(P=0.042),and prevalence of thrombotic microangiopathy(P=0.046)than the patients showing AKI at the first renal biopsy(n=16),while the activity index(AI)showed no significant difference(P=0.051).Over 50% of NS and AKI patients underwent treatment modifications post-repeat renal biopsy,with clinical remission rates comparable to those after the first renal biopsy(both P>0.05).Elevated CI(≥5,P=0.001)and serum creatinine(≥140 μmol/L,P<0.001)at repeat renal biopsy were identified as independent risk factors for poor prognosis.The patients with AKI at repeat renal biopsy had higher incidence of endpoint events than the non-AKI patients(P=0.015).Neither AKI at the first renal biopsy nor NS at both biopsies had significant associations with prognosis. Conclusions Repeat renal biopsy reveals not only sustained high disease activity but also accelerates chronic progression in LN patients,which underscore its critical role in guiding the therapy for severe LN post-immunosuppression.AKI,CI≥5,and serum creatinine ≥140 μmol/L at repeat renal biopsy are strongly associated with poor prognosis.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Objective:To construct and evaluate a risk warning model for enteral nutrition associated diarrhea(ENAD)in acute stroke patients based on logistic regression and Nomogram.Methods:This study was a retrospective study,a total of 172 patients with acute stroke who were admitted to Yancheng First People's Hospital from January 2022 to May 2024 were selected,and clinical data of patients were collected.Multivariate logistic regression analysis was used to identify the influencing factors of ENAD occurrence,based on the results of the multivariate logistic regression analysis,a Nomogram warning model was constructed,the receiver operating characteristic(ROC)curve was applied to analyze the predictive value of the Nomogram warning model for the risk of ENAD occurrence in patients with acute stroke.Results:Univariate analysis showed that,the occurrence of ENAD in patients with acute stroke was related to fasting time,mechanical ventilation,oral potassium preparations,albumin,number of types of antibiotics used,acute physiology and chronic health status Ⅱ(APACHE Ⅱ)score,enteral nutrition infusion rate,length of stay in the intensive care unit(ICU),use of proton pump inhibitors,duration of antibiotic use,use of gastrointestinal prokinetic drugs,and daily enteral nutrition infusion volume(P＜0.05).The results of multiple logistic regression analysis showed that,high APACHE Ⅱ score,prolonged use of antibiotics,low albumin,use of gastrointestinal prokinetic drugs,oral potassium preparations,prolonged fasting time,and rapid enteral nutrition infusion were risk factors for ENAD in patients with acute stroke(P＜0.05).Construct and validate a Nomogram warning model based on the results of multiple logistic regression analysis.After evaluation,the model fits well with an area under the curve(AUC)of 0.823,indicating high predictive value for ENAD occurrence in patients with acute stroke.Conclusion:High APACHE Ⅱ score,prolonged use of antibiotics,low albumin,use of gastrointestinal prokinetic drugs,oral potassium preparations,prolonged fasting time,and rapid enteral nutrition infusion are risk factors for ENAD in patients with acute stroke.The Nomogram warning model constructed based on the above indicators has high predictive value for the occurrence of ENAD in patients with acute stroke.

Bovine rotavirus(BRV)is an important pathogen causing diarrhea in calves.To understand the genomic charac-teristics and genetic variations in bovine rotavirus,and to further enrich data on the biological characteristics of rotavirus,we aimed to amplify 11 gene segments of the isolated and cultured G6P[1]bovine rotavirus BLL strain,perform whole genome se-quencing,and analyze the molecular characteristics.MEGA7.0 and DNAMAN software were used for homology and typing a-nalysis,and the whole genome phylogenetic tree was constructed to analyze genetic evolution relationships.The complete geno-type of the BLL strain was G6-P[1]-I2-R2-C2-M2-A3-N2-T6-E2-H3.Phylogenetic analysis of the VP7 and VP4 genes of the BLL strain showed that the VP7 gene had the highest homology with RVA/Cow-wt/HB01/China/2021,and the VP4 gene of the BLL strain was in the same branch as RVA/Human-tc/ISR/Ro8059/1995.From the sequence alignment of VP8*amino acids,the sialic acid domain of the BLL strain was found to be similar to that in other P[1]strains,but different from those in other types of strains,except for residue 189,which was the same as that in Ro8059 but different from that in other strains.The results suggested that the BLL strain might potentially infect humans.Therefore,continued monitoring and study of the biological characteristics of this strain are necessary to provide more information and evidence supporting further research on the cross-species transmission of group A rotavirus in China.
