Objective To study the five-year survival status and influencing factors of elderly patients with lung cancer complicated with chronic obstructive pulmonary disease (COPD). Methods A cohort study was conducted to follow up 450 patients with lung cancer and chronic obstructive pulmonary disease who were hospitalized in our hospital from January 2018 to December 2023. The endpoint of the follow-up was the end of a five-year period or death. The Life Tables method was used to calculate survival rates and plot survival curves. The Cox proportional hazards model was used to analyze the influencing factors of five-year survival. Results The results indicated that the overall five-year survival rate of patients was 4.89%, and it decreased year by year. Cox regression analysis showed that age, gender, family functioning, and psychological status significantly influenced patient survival rate (all P<0.05). Stratified analysis found that the smoking status, family functioning, and psychological status of male patients all had an impact on survival rate (all P<0.05), while the psychological status of female patients had a more significant impact on survival (P=0.008). Conclusion This study provides a scientific basis for comprehensive intervention of elderly lung cancer patients with COPD. It is recommended that clinical attention should be paid to psychological and family factors to improve patient prognosis.

AIM:To investigate the expression levels of serum sirtuin 6(Sirt6)and nicotinamide adenine dinucleotide phosphate oxidase 2(NOX2)in patients with primary glaucoma and their correlation with the severity of the disease. METHODS:This study is a cross-sectional study. Patients diagnosed with primary glaucoma at the hospital from August 2022 to June 2025 were enrolled and divided into mild-to-moderate and severe groups based on the mean deviation of visual field defects, along with healthy individuals as a control group. Clinical data were collected, and serum levels of Sirt6 and NOX2 were measured using enzyme-linked immunosorbent assay(ELISA). Correlations between serum Sirt6 and NOX2 levels and clinical parameters were analyzed. Multivariate Logistic regression was used to identify factors influencing disease severity, and the diagnostic efficacy of serum Sirt6 and NOX2 levels was evaluated using receiver operating characteristic(ROC)curves. RESULTS:A total of 120 patients with primary glaucoma(58 males, 62 females, mean age 60.08±8.19 y)and 100 controls(46 males, 56 females, mean age 60.23±8.67 y)were enrolled in this study. There were no statistically significant differences in sex or age between the two groups(both P>0.05). The intraocular pressure and serum NOX2 expression level in the primary glaucoma group were significantly higher than those in the control group, while the Sirt6 level was significantly lower than in the control group(all P<0.001). The AUC values of serum Sirt6 and NOX2 in the diagnosis of primary glaucoma were 0.733 and 0.770, respectively, with optimal cutoff values of 2.35 and 4.25 ng/mL, respectively. The AUC of the combined diagnosis of the two was 0.901, and its efficacy was obviously better than that of a single indicator(Zcombination-Sirt6=5.317, Zcombination-NOX2=4.720, P<0.001).The severe group had lower serum Sirt6 expression levels(P<0.05), and higher NOX2 expression levels(P<0.05)than the mild-to-moderate group. Serum Sirt6 expression levels were prominently negatively correlated with mean intraocular pressure(r=-0.354, P<0.05); NOX2 expression levels were prominently positively correlated with mean intraocular pressure(r=0.240, P<0.05). Multivariate Logistic regression analysis showed that a decrease in serum Sirt6 expression levels(OR=0.229, 95%CI: 0.090-0.581), an increase in serum NOX2 expression levels(OR=2.649, 95%CI: 1.658-4.232), an increase in mean intraocular pressure(OR=1.278, 95%CI: 1.118-1.462)which were risk factors for the progression to severe glaucoma. The AUC values of serums Sirt6 and NOX2 expression levels in diagnosing severe primary glaucoma were 0.794 and 0.800, respectively, the AUC, sensitivity, and specificity of the combined diagnosis of the two were 0.916, 80.00%, and 89.33%, respectively, and the combined diagnostic efficacy was better than that of a single indicator(Zcombination-Sirt6=2.627, P=0.009, Zcombination-NOX2=2.762, P=0.006). CONCLUSION:The decreased serum Sirt6 and increased NOX2 expression levels in patients with primary glaucoma are significantly correlated with disease severity, and the combined detection demonstrates good diagnostic value for primary glaucoma and its severity.

AIM:To analyze the influencing factors of visual outcome after vitrectomy for polypoidal choroidal vasculopathy(PCV)combined with vitreous hemorrhage and establish a predictive model.METHODS: A retrospective analysis was conducted on the clinical data of 129 cases(129 eyes)of patients who underwent vitrectomy for PCV combined with vitreous hemorrhage from June 2021 to January 2024 in our hospital. They were divided into elevated group(71 eyes)and non-elevated group(58 eyes)according to visual outcome at early posoperative stage(within 24 mo). Another 30 cases(30 eyes)of PCV with vitreous hemorrhage undergoing vitrectomy were selected as external validation data. The predictive value of the model for the postoperative visual outcomes of both internal and external populations was evaluated.RESULTS: The non-elevated group had a higher proportion of patients aged ≥60 years, diabetes, continuous abnormalities of the ellipsoid zone(EZ)during surgery, bleeding involving the macular fovea, and postoperative retinal scar formation than the elevated group were independent factors affecting postoperative visual acuity(all P<0.05). The AUC of the predictive model for predicting the postoperative visual outcomes of internal and external populations was 0.824(95%CI: 0.750-0.898)and 0.809(95%CI: 0.723-0.865), respectively.CONCLUSION:Patients aged ≥60 years, diabetes, intraoperative continuous abnormalities of EZ, bleeding involving the macular fovea, and postoperative retinal scar formation are influencing factors for visual outcome after vitrectomy in patients with PCV combined with vitreous hemorrhage. A predictive model based on those factors has been established, which has a certain predictive value for postoperative visual outcome.

This study investigated the role of the nuclear factor of activated T cells c3 (NFATc3) in vascular smooth muscle cells (VSMCs) during aortic aneurysm and dissection (AAD) progression and the underlying molecular mechanisms. Cytoplasmic and nuclear NFATc3 levels were elevated in human and mouse AAD. VSMC-NFATc3 deletion reduced thoracic AAD (TAAD) and abdominal aortic aneurysm (AAA) progression in mice, contrary to VSMC-NFATc3 overexpression. VSMC-NFATc3 deletion reduced extracellular matrix (ECM) degradation and maintained the VSMC contractile phenotype. Nuclear NFATc3 targeted and transcriptionally upregulated matrix metalloproteinase 9 (MMP9) and MMP2, promoting ECM degradation and AAD development. NFATc3 promoted VSMC phenotypic switching by binding to eukaryotic elongation factor 2 (eEF2) and inhibiting its phosphorylation in the VSMC cytoplasm. Restoring eEF2 reversed the beneficial effects in VSMC-specific NFATc3-knockout mice. Cabamiquine-targets eEF2 and inhibits protein synthesis-inhibited AAD development and progression in VSMC-NFATc3-overexpressing mice. VSMC-NFATc3 promoted VSMC switch and ECM degradation while exacerbating AAD development, making it a novel potential therapeutic target for preventing and treating AAD.

Objective:To mine risk signals of adverse events (AE) in agalsidase beta therapy for Fabry disease and provide reference for the safe use in clinical practice.Methods:The AE reports with agalsidase beta as the primary suspect drug in the US Food and Drug Administration Adverse Event Reporting System (FAERS) database from the first quarter of 2004 to the third quarter of 2024 were collected and the clinical information of patients involved was analyzed descriptively. AEs were standardized and categorized using the preferred term (PT) and system organ class (SOC) in Medical Dictionary for Regulatory Activities version 26.0. Signal mining was performed using the reporting odds ratio (ROR) method and Bayesian confidence propagation neural network (BCPNN) method. A PT was defined as the risk signal if the number of reports was ≥3, the lower limit of the 95% confidence interval ( CI) of ROR was >1, and the information component minus two times standard deviation ( IC025) was >0. Descriptive statistical analysis were then conducted on the risk signals. The relative risk of target adverse events in gender subgroups was evaluated using the ROR method. Results:A total of 24 163 AE reports with agalsidase beta as the primary suspect drug were collected, involving 7 763 patients and 2 382 PTs. Severe adverse events accounted for 34.9% (2 712/7 763). A total of 121 risk signals (namely PTs) across 15 SOCs were obtained. The top 5 PTs ranked by number of reports were pyrexia (483 cases), chills (449 cases), infusion related reaction (282 cases), chest pain (221 cases), and cerebrovascular accident (218 cases). The top 5 PTs ranked by signal intensity were cornea verticillata ( ROR=56.44, IC025=4.59), drug specific antibody present ( ROR=54.13, IC025=5.46), cerebral calcification ( ROR=24.82, IC025=3.16), myocardial necrosis marker increased ( ROR=24.14, IC025=3.83), and infusion site rash ( ROR=20.41, IC025=3.46). Among the top 30 PTs ranked by number of reports and signal intensity, there were 4 and 13 PTs not documented in the drug label, respectively. The former included atrial fibrillation, cellulitis, neuralgia, and pallor, while the latter included cornea verticillate, cerebral calcification, auricular swelling, vein discoloration, aortic dilatation, bundle branch block, myocardial fibrosis, cardiac infection, vein rupture, sudden hearing loss, meningitis viral, deafness transitory, and corneal opacity. Subgroup analysis by sex showed that males had higher risks in developing chills, tremor, drug specific antibody detection, renal failure, and renal impairment, while females had higher risks in weight increase and dizziness. Conclusions:The main risk signals of adverse events of agalsidase beta include pyrexia, chills, and infusion related reactions, which are consistent with those documented in package inserts. In addition, potential new risk signals such as atrial fibrillation, cellulitis, neuralgia, cornea verticillate, auricular swelling, and sudden hearing loss were also detected. The relative risks of some target adverse events vary between genders, and it is recommended to strengthen targeted drug monitoring and individualized management in clinical practice.

Objective:To observe the changes of macular structure and microvessels in eyes with diabetes macular ischemia (DMI).Methods:A retrospective case study. From January 2023 to July 2023, 23 patients of 31 eyes diagnosed with DMI at Tangshan Ophthalmological Hospital were included in this study. Among them, there were 14 males with 23 eyes; Female cases with 8 eyes. Age were (59.5±4.6) years old. According to the DMI grading standard formulated by the research group for early treatment of diabetes retinopathy, the patients were divided into mild DMI group, moderate DMI group, and severe DMI group, with 8, 12, and 11 eyes respectively. The blood flow density (VD), perfusion area (FA), small vessel VD (SVD), inner retinal capillary plexus VD, FA, and outer retinal, choroidal, and ganglion cell complex (GCC) thickness within 1 mm of the macular fovea in retinal superficial vascular plexus (SVP)were measured using a scanning frequency light source optical coherence tomography instrument. The changes in macular structure and microvasculature in the affected eyes of different degrees of DMI groups were compared and observed. Inter group comparisons were conducted using one-way ANOVA or Kruskal Wallis H-test. Spearman correlation analysis was used to analyze the correlation between DMI severity and GCC, outer retina, choroid thickness, VD, FA and SVP VD, SVD and FA in inner retina. Results:The GCC ( F=70.670), outer retinal thickness ( H=12.393), VD ( F=105.506), SVD ( H=25.300), FA ( F=107.655), and VD ( H=24.098) and FA ( H=25.300) of the retinal SVP in the mild, moderate, and severe DMI groups were compared, and the differences were statistically significant ( P<0.05). There was no statistically significant difference in choroidal thickness ( H=2.441, P>0.05). Pairwise comparison between groups: VD, SVD, FA of GCC thickness and SVP, and VD of inner retina were statistically significant between severe DMI group and moderate DMI group, and between moderate DMI group and mild DMI group ( P<0.05). The thickness of outer retina was statistically significant between severe DMI group and moderate DMI group ( P<0.05). Inner retinal FA: there were statistically significant differences between severe DMI group, moderate DMI group and mild DMI group ( P<0.05). The correlation analysis results showed that GCC ( r s=-0.918), outer retinal thickness ( r s=-0.448), and inner retinal VD ( r s=-0.894) and FA ( r s=-0.918), as well as VD ( r s=-0.919), SVD ( r s=-0.924), and FA ( r s=-0.939) of retinal SVP, were all negatively correlated with the degree of DMI ( P<0.05). There was no correlation between choroidal thickness and degree of DMI ( r s=-0.081, P>0.05). Conclusion:The thickness of GCC, outer retina and choroid, the VD, SVD, and FA of the retinal SVP, the VD and FA of inner retina are all reduced in eyes with different degrees of DMI, while all of them are negatively correlated with the degree of DMI, except for choroid thickness.

AIM:To investigate the mechanism of action of Wenweiyang decoction(WWYD)in treating func-tional dyspepsia in rats based on mast cell activation and stem cell factor(SCF)/receptor tyrosine kinase c-Kit signaling pathway.METHODS:Sixty SD rats were randomly divided into control group,model group,ranitidine hydrochloride capsule group,and low-,medium-and high-dose WWYD groups,with 10 rats in each group.The rat model of functional dyspepsia was established by tail clamping and irregular feeding compound senna method.After modeling,the rats in con-trol group and model group were given normal saline,while those in low-,medium-and high-dose(0.743 g/mL,1.485 g/mL and 2.970 g/mL)WWYD groups and ranitidine hydrochloride capsule(3 g/L)group were treated with corresponding drugs by intragastric administration.After treatment,the propulsion rate of the small intestine was measured by the carbon ink propulsion method.Rat duodenal mast cells were observed and counted by toluidine blue staining.ELISA was used for determination of mast cell tryptase(MCT)and histamine(HA)content in rat duodenum.The mRNA levels of SCF and c-Kit in duodenum were detected by RT-qPCR.Western blot and immunohistochemistry were employed to determine the ex-pression levels of SCF and c-Kit in the duodenum.RESULTS:Compared with model group,WWYD treatment signifi-cantly increased the propulsion rate of the small intestine in rats(P<0.05).ELISA results showed that WWYD reduced the number of mast cells and the content of MCT and HA in the duodenal mucosa tissue of rats(P<0.05).Western blot and immunohistochemistry results suggested that WWYD up-regulated the protein expression levels of c-Kit and SCF in the duodenal tissue of rats(P<0.05),and increased the numbers of SCF and c-Kit positive cells.RT-qPCR results indicated that WWYD up-regulated the mRNA expression of c-Kit and SCF in the duodenum of rats(P<0.05).Moreover,the small intestinal propulsion rate was negatively correlated with MCT and HA content,and positively correlated with the expres-sion of SCF and c-Kit.CONCLUSION:Wenweiyang decoction promotes rat duodenal motility,and its mechanism may be related to the inhibition of rat duodenal MCT and HA production and activation of SCF/c-Kit signaling pathway.

Objective To investigate the virological features of patients with chronic hepatitis B(CHB)and metabolic associated fatty liver disease(MAFLD)through a stratified analysis.Methods A retrospective analysis was performed for 131 patients with CHB and MAFLD and 168 patients with CHB alone who underwent percutaneous liver biopsy and did not receive antiviral therapy or withdrew from drugs for more than 6 months in Beijing YouAn Hospital,Capital Medical University,from January 1,2013 to December 31,2019.The two groups were compared in terms of general data,biochemical parameters,and virological parameters.The patients in the two groups were stratified according to liver inflammation grade(G)and liver fibrosis stage(S),and the patients with CHB and MAFLD were further analyzed based on the degree of hepatic steatosis and NAFLD activity score(NAS).Virological features(the serum levels of HBV DNA and HBV HBsAg)were compared between groups.The Wilcoxon test was used for comparison of continuous data between two groups,and the Kruskal-Wallis H test was used for comparison between multiple groups and further comparison between two groups;the chi-square test was used for comparison of categorical data between two groups.Results Compared with the CHB group,the CHB+MAFLD group had a significantly higher proportion of male patients,a significantly higher proportion of patients with hypertension or type 2 diabetes mellitus,and significantly higher levels of the blood biochemical parameters of triglyceride,low-density lipoprotein cholesterol,apolipoprotein B,alanine aminotransferase,gamma-glutamyl transpeptidase,uric acid,and fasting blood glucose(all P<0.05),as well as significantly lower levels of high-density lipoprotein cholesterol,apolipoprotein A1,and HBV DNA(all P<0.05).The stratified analysis based on liver fibrosis stage showed that for both the patients with CHB alone and those with CHB and MAFLD,the significant fibrosis(S2—4)group had a significantly lower level of HBV DNA than the non-significant fibrosis(S0—1)group(P<0.05),and for the patients with CHB alone,the significant fibrosis(S2—4)group had a significantly lower level of HBsAg than the non-significant fibrosis(S0—1)group(P<0.05).The stratified analysis based on inflammation grade showed that for the patients with CHB and MAFLD,the high inflammation grade(G3)group had a significantly higher level of HBV DNA than the low inflammation grade(G1—2)group(P<0.05),and in the low inflammation grade(G1—2)group,the patients with CHB and MAFLD had a significantly lower level of HBsAg than the patients with CHB alone(P<0.05).The stratified analysis based on the degree of hepatic steatosis showed that the level of HBV DNA gradually decreased with the increase in the degree of steatosis,and the severe steatosis group had a significantly lower level of HBV DNA than the mild group(P<0.05),while there was no significant difference in HBsAg level between the groups with different degrees of hepatic steatosis(P>0.05).The stratified analysis based on NAS score showed that the NAS≥4 group had significantly higher levels of HBV DNA and HBsAg than the NAS<4 group(both P<0.05).Conclusion Patients with CHB and MAFLD have significant abnormalities in metabolic markers and aminotransferases,while virological indicators show different features in stratified analyses based on various indicators.
