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: This study examines utilizes the advantages of machine learning algorithms to discern key determinants in prognosticate postoperative circulatory complications (PCCs) for older patients. METHODS: This secondary analysis of data from a randomized controlled trial involved 1,720 elderly participants in five tertiary hospitals in Beijing, China. Participants aged 60-90 years undergoing major non-cardiac surgery under general anesthesia. The primary outcome metric of the study was the occurrence of PCCs, according to the European Society of Cardiology and the European Society of Anaesthesiology diagnostic criteria. The analysis metrics contained 67 candidate variables, including baseline characteristics, laboratory tests, and scale assessments. RESULTS: Our feature selection process identified key variables that significantly impact patient outcomes, including the duration of ICU stay, surgery, and anesthesia; APACHE-II score; intraoperative average heart rate and blood loss; cumulative opioid use during surgery; patient age; VAS-Move-Median score on the 1st to 3rd day; Charlson comorbidity score; volumes of intraoperative plasma, crystalloid, and colloid fluids; cumulative red blood cell transfusion during surgery; and endotracheal intubation duration. Notably, our Random Forest model demonstrated exceptional performance with an accuracy of 0.9872. CONCLUSION We have developed and validated an algorithm for predicting PCCs in elderly patients by identifying key risk factors.

OBJECTIVE: To describe survival trends and global patterns of esophageal cancer (EC) using survival data from population-based cancer registries. METHODS: We systematically searched PubMed, EMBASE, Web of Science, SEER, and SinoMed databases for articles published up to 31 December 2023. Eligible EC survival estimates were evaluated according to country or region, period, sex, age group, pathology, and disease stage. RESULTS: After 2010, Jordan exhibited the highest age-standardized 5-year relative survival rates (RSRs)/net survival rates (NSRs) at 41.1% between 2010 and 2014, while India had the lowest, at 4.1%. Survival rates generally improved with diagnostic age across most countries, with significant increases in South Korea and China, of 12.7% and 10.5% between 2000 and 2017, respectively. Survival was higher among women compared to men, ranging from 0.4%-10.9%. Survival rates for adenocarcinoma and squamous cell carcinoma were similar, differing by about 4%. In China, the highest age-standardized RSRs/NSRs was 33.4% between 2015 and 2017. Meanwhile, the lowest was 5.3%, in Qidong (Jiangsu province) between 1992-1996. CONCLUSION Global EC survival rates have improved significantly in recent decades, but substantial geographical, sex, and age disparities still exist. In Asia, squamous cell carcinoma demonstrated superior survival rates compared to adenocarcinoma, while the opposite trend was observed in Western countries. Future research should clarify the prognostic factors influencing EC survival and tailor prevention and screening strategies to the changing EC survival patterns.

OBJECTIVES: This study aimed to investigate the impact of foam macrophages (FMs) on the intracellular survival of Mycobacterium tuberculosis (MTB) and identify the molecular mechanisms influencing MTB survival. METHODS: An in vitro FM model was established using oleic acid induction. Transcriptomic and metabolomic analyses were conducted to identify the key molecular pathways involved in FM-mediated MTB survival. RESULTS: Induced FMs effectively restricted MTB survival. Transcriptomic and metabolomic profiling revealed distinct changes in gene and metabolite expression in FMs during MTB infection compared with normal macrophages. Integrated analyses identified significant alterations in the cyclic adenosine monophosphate (cAMP) signaling pathway, indicating that its activation contributes to the FM-mediated restriction of MTB survival. CONCLUSIONS FMs inhibit MTB survival. The cAMP signaling pathway is a key contributor. These findings enhance the understanding of the role of FMs in tuberculosis progression, suggest potential targets for host-directed therapies, and offer new directions for developing diagnostic and therapeutic strategies against tuberculosis.

OBJECTIVE: To investigate chronic hepatitis C virus (HCV) infection's effect on gestational liver function, pregnancy and delivery complications, and neonatal development. METHODS: A total of 157 HCV antibody-positive (anti-HCV[+]) and HCV RNA(+) patients (Group C) and 121 anti-HCV(+) and HCV RNA(-) patients (Group B) were included as study participants, while 142 anti-HCV(-) and HCV RNA(-) patients (Group A) were the control group. Data on biochemical indices during pregnancy, pregnancy complications, delivery-related information, and neonatal complications were also collected. RESULTS: Elevated alanine aminotransferase (ALT) rates in Group C during early, middle, and late pregnancy were 59.87%, 43.95%, and 42.04%, respectively-significantly higher than Groups B (26.45%, 15.70%, 10.74%) and A (23.94%, 19.01%, 6.34%) ( P < 0.05). Median ALT levels in Group C were significantly higher than in Groups A and B at all pregnancy stages ( P < 0.05). No significant differences were found in neonatal malformation rates across groups ( P > 0.05). However, neonatal jaundice incidence was significantly greater in Group C (75.16%) compared to Groups A (42.25%) and B (57.02%) ( χ ² = 33.552, P < 0.001). HCV RNA positivity during pregnancy was an independent risk factor for neonatal jaundice ( OR = 2.111, 95% CI 1.242-3.588, P = 0.006). CONCLUSIONS Chronic HCV infection can affect the liver function of pregnant women, but does not increase the pregnancy or delivery complication risks. HCV RNA(+) is an independent risk factor for neonatal jaundice.

Chrysophanol(Chr)and physcion(Phy)are primary active ingredients of a well-known traditional Chinese medicine namely rhubarb(Chinese name:Dahuang),and their glucuronides have been revealed as the dominant forms presenting in rats after oral administration.Either Chr or Phy has two glycosylation sites,resulting in a pair of positional isomers for glucuronides of either compound(CG1&CG2 and PG1&PG2).To confirmatively identify these glucuronides,energy-resolved mass spectrometry(ER-MS)was used to pursue the fragmentation trajectories of the targeted fragment ions,and the resultant breakdown graphs that were described by the optimal collision energy(OCE)were expected to exhibit the differences of glycosidic bond cleavage between the isomers.Quantum chemical calculation was thereafter conducted to produce the bond dissociation energy(BDE)of the glycosidic bonds.The isomers were unambiguously identified through applying the positive correlation rule between OCE and BDE.Fortunately,the glucuronides of Chr and Phy in vivo were observed through liver microsomes incubationin vitro.ER-MS was utilized to collect the Gaussian-shaped breakdown graphs in response to the neutral loss of 176 Da,and the absolute values of OCE were compared between positional isomers.The results revealed that CG1(-32.31 eV)>CG2(-31.61 eV),and nonetheless,PG1(-30.00 eV)Chr-8-GluA(-48.787 kJ/mol),and nonetheless,Phy-1-GluA(-48.672 kJ/mol)

Objective To investigate the comparative neuroprotective effects of human umbilical cord mesenchymal stem cells(hUC-MSCs-Exos)administered via different routes on hypoxic ischemic brain damage(HIBD)in neonatal mice.Methods Healthy one-week-old SPF-grade BALB/c mice were randomly divided into 4 groups:sham operation group(n=6),model group(n=6),exosome group 1(n=8),exosome group 2(n=8).HIBD was induced using the Rice-Vannucci method.Exosome group 1 and Exosome group 2 were intraperitoneal injection/intranasal drip of phosphate buffer(PBS)100 μl containing 10 μl exosomes within 24 h after successful modeling,respectively.Sham operation and model groups were intraperitoneal injection of PBS 100 μl.On the 7th day after the intervention,neuromotor function was assessed using the horizontal grid test and pole climbing test.On the 2nd day after the evaluation,all mice were killed and their brains were removed by decapitation.HE staining was used to observe the pathological injury of brain tissue,toluidine blue staining was used to observe the survival of neurons in cerebral cortex,and TUNEL staining was used to observe the apoptosis of cerebral cortex cells.Results Compared with sham operation group,model group,exosome group 1 and exosome group 2 exhibited increased hind limb drops in horizontal grid test and climbing scores(P<0.05).No significant difference was found in model group,exosome group 1 and exosome group 2 in these measures(P<0.05).Significant pathology was observed in model group,exosome group 1 and exosome group 2 compared to sham operation group(P<0.05),with significantly reduced damage in exosome group 1 and exosome group 2 compared to model group(P<0.05).Compared with sham operation group,Nissl body count was lower in model group and exosome group 1 and exosome group 2,with a higher count in exosome group 2 compared to exosome group 1(P<0.05).Compared with sham operation group,apoptotic cells were higher in model group and exosome group 1 and exosome group 2,with a significant reduction in exosome group 1 and exosome group 2 compared to model group,and the lowest in exosome group 2(P<0.05).Conclusions hUC-MSCs-Exos can improve the neuronal motor function,promote neuron repair and inhibit apoptosis in HIBD mice.Intranasal administration of hUC-MSCs-Exos is more effective than intraperitoneal administration for reducing neuronal apoptosis in HIBP neonatal mice,offering a convenient and rapid method suitable for clinical application.

Objective To investigate the role of the neutrophil-to-lymphocyte ratio(NLR)in predicting the in-hospital mortality risk of patients with acute aortic dissection(AAD)in multicenter hospitals.Methods A multicenter retrospective cohort study was conducted.Clinical data were collected from 2642 AAD patients who were hospitalized in five teaching hospitals:Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology,Henan Provincial People's Hospital,Fuwai Central China Cardiovascular Hospital,the Third Affiliated Hospital of Xinxiang Medical University,and the Second Affiliated Hospital of Chongqing Medical University between August 2010 and December 2021.According to the quartiles of serum NLRlevels,the patients were divided into four groups:first quartile(Q1,n=660),second quartile(Q2,n=661),third quartile(Q3,n=661),and fourth quartile(Q4,n=660).The clinical characteristics and biochemical indicators of each group were compared.Partial correlation analysis was used to assess the relationship between NLR and cardiovascular parameters.Restricted cubic splines,Kaplan-Meier survival analysis,and Cox regression models were employed to evaluate the association between NLR levels and in-hospital mortality risk in AAD patients.Results The median age of all patients was 54[interquartile range(IQR):46-63]years,including 2096 males and 546 females.Compared with Q1-Q3 groups,patients inQ4group had a lower incidence of smoking history and diabetes history,and were more likely to have DeBakey type Ⅰ AAD(P＜0.05).Additionally,the levels of aspartate aminotransferase,high-density lipoprotein cholesterol,creatinine,and D-dimer in Q4 group were higher,while the levels of triglycerides and C-reactive protein(CRP)were lower(P＜0.01).The results of partial correlation analysis showed that the plasma NLR level was positively correlated with D-dimer(r=0.43,P＜0.01)and creatinine(r=0.16,P＜0.01).The restricted cubic spline function in the Cox model revealed a significant non-linear relationship between the plasma NLR level and clinical outcomes in AAD patients(P＜0.01).Kaplan-Meier survival analysis indicated that patients in Q4 group had the highest in-hospital mortality rate compared with Q1-Q3 groups(P＜0.0001).Furthermore,multivariate Cox regression analysis demonstrated that compared with Q1 group,the hazard ratio(HR)of NLR in Q4 group was 1.77(95％CI 1.33-2.37,P＜0.001),which was an independent risk factor for the primary endpoint events.Conclusion A higher plasma NLR level is significantly associated with the occurrence of cardiovascular events in AAD patients,and this association remains significant even after adjusting for potential confounding factors such as the multicenter visiting hospitals.

Objective To explore the clinical characteristics and influencing factors in type 2 diabetes mellitus(T2DM)patients with metabolic-associated fatty liver disease(MAFLD)who are at moderate-to-high risk of metabolic-associated fatty liver fibrosis.Methods A retrospective analysis was conducted on the clinical data of 495 T2DM patients with MAFLD who were treated in the Department of Endocrinology,the Seventh People's Hospital Affiliated to Shanghai University of Traditional Chinese Medicine,from August 2022 to May 2024.According to the fibrosis-4(FIB-4)index,the patients were divided into two groups:low risk group for metabolic-associated fatty liver fibrosis(n=311)and moderate-to-high risk group for metabolic-associated fatty liver fibrosis(n=184).Differences in clinical characteristics and laboratory test results between the two groups were compared.Univariate and multivariate binary logistic regression analyses were used to screen the influencing factors of moderate-to-high risk of metabolic-associated fatty liver fibrosis in T2DM patients with MAFLD.Receiver operating characteristic(ROC)curves and area under the curve(AUC)were employed to evaluate the predictive value of these factors for moderate-to-high risk of metabolic-associated fatty liver fibrosis in T2DM patients with MAFLD.Results Compared with low risk group,moderate-to-high risk group had significantly higher age,proportions of patients with a history of hypertension and coronary heart disease,as well as higher levels of aspartate aminotransferase(AST),blood urea nitrogen(BUN),and creatinine(Cr)(P<0.05).In contrast,moderate-to-high group had a lower proportion of male patients,and lower levels of platelet count(PLT),total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C),glycated hemoglobin(HbA1c),free triiodothyronine(FT3),free thyroxine(FT4),and thyroid feedback quantile-based index(TFQI)(P<0.05).Univariate binary logistic regression analysis showed that male(P=0.020),HbA1c(P=0.014),BUN(P<0.001),Cr(P<0.001),TC(P=0.001),LDL-C(P<0.001),FT3(P<0.001),FT4(P<0.001),and TFQI(P=0.039)were influencing factors for moderate-to-high risk of metabolic-associated fatty liver fibrosis in T2DM patients with MAFLD.Multivariate binary logistic regression analysis revealed that BUN(OR=1.165,95%CI 1.006-1.348,P=0.042)and Cr(OR=1.020,95%CI 1.005-1.036,P=0.008)were independent risk factors for moderate-to-high risk of metabolic-associated fatty liver fibrosis in T2DM patients with MAFLD,while male(OR=0.574,95%CI 0.339-0.972,P=0.039),LDL-C(OR=0.659,95%CI 0.483-0.898,P=0.008),FT3(OR=0.590,95%CI 0.404-0.864,P=0.007),and FT4(OR=0.863,95%CI 0.762-0.977,P=0.020)were independent protective factors.ROC curve analysis showed that the AUC of the combined 6 influencing factors for predicting moderate-to-high risk of metabolic-associated fatty liver fibrosis in T2DM patients with MAFLD was 0.728(95%CI 0.682-0.774),with a sensitivity of 0.620 and a specificity of 0.759.Conclusions Gender,BUN,Cr,LDL-C,FT3,and FT4 are independent influencing factors for moderate-to-high risk of metabolic-associated fatty liver fibrosis in T2DM patients with MAFLD.Monitoring and early intervention for the above abnormal biochemical indices are beneficial in delaying the occurrence and development of liver fibrosis in T2DM patients with MAFLD.

Objective To investigate the mechanism of hippocampal neuronal plasticity of newborn neurons in the hippocampus by which exercise improves the fear and anxiety symptoms of post-traumatic stress disorder(PTSD).Methods Totally 40 C57BL/6J male mice were randomly divided into by control group(Ctrl)and PTSD group,the PTSD group was divided into a no-exercise group(PTSD),a low-intensity exercise group(L)and a high-intensity exercise group(H).The PTSD model mice were constructed by combining conditioned plantar-foot shock(CF)and single-session sustained stress(SPS).After the exercise intervention,the fear and anxiety levels of the mice were assessed using the conditioned fear test and the elevated cross maze test;Subsequently,the densities of the newborn mature neurons in dentate gyrus(DG)of hippocampus were detected by immunofluorescent double-labelling staining,and the newborn neuron morphology was marked by injecting retrovirus pRetro-U6-EF1-EGFP-3xFLAG-WPRE in DG of hippocampus to observe its morphology.The morphology of the newborn neurons was labelled to observe their dendritic length and the number of branch points;Meanwhile,the concentration level of adiponctin(APN)in the hippocampal area was determined by ELISA.Results The result showed that both high and low-intensity exercise interventions significantly reduced the freezing time of PTSD mice in the conditioned fear test,and in the elevated cross maze experiment,the residence time and the number of entries in the open arm of the mice in the H group increased significantly compared with those in the PTSD group,while the residence time and the number of entries in the closed arm were significantly reduced.In addition,both high and low-intensity exercise interventions significantly increased the surface density and dendritic length of newborn mature neurons in the hippocampal DG region of PTSD mice,and high-intensity exercise significantly increased the number of dendritic branching points,and the density of newborn mature neurons in the H group was more significantly increased compared with that in the L group.At the same time,the hippocampal APN concentration increased significantly in both L and H groups compared with the PTSD group,and it was more significant in the H group.Conclusion Exercises have an ameliorative effect on anxiety and fear symptoms in PTSD mice,and at the same time,it can increase hippocampal neuroplasticity and adiponctin secretion in PTSD mice,suggesting that the improvement of fear and anxiety symptoms in PTSD by exercise may be related to the increase of hippocampal neuroplasticity and APN secretion,and the improvement effect is better with high-intensity exercise.
