Artificial intelligence (AI) has made preliminary advances in the management of postoperative follow up for lung cancer; however, a systematic review of its application value across the entire follow-up continuum remains lacking. Taking the four core dimensions of postoperative follow-up management as its framework, including surveillance candidate selection, follow-up interval optimization, follow-up protocol design, and follow-up modality selection, this review examines the progress of AI in patient risk stratification, surveillance frequency optimization, content design, and supportive platform development. The review further delineates the current challenges and future directions for AI in this domain, and ultimately seeks to promote the standardized and scaled application of AI in postoperative follow-up management for lung cancer, with the goal of establishing a "care beyond hospitalization" life-cycle management framework that improves the long-term quality of survival for patients undergoing lung cancer surgery.

Objective To compare the clinical efficacy of PCI with radial artery approach and bra-chial artery approach in acute myocardial infarction(AMI).Methods A retrospective analysis was performed on 173 AMI patients undergoing PCI in Department of Cardiology of Affiliated Hospi-tal of Chengde Medical College from September 2022 to September 2024.According to surgical ap-proach,they were divided into the radial artery group(97 cases)and the brachial artery group(76 cases).The X-ray exposure rate,puncture time,operation time and total hospital stay were observed in the two groups,and the puncture success rate,postoperative complication rate and incidence of 30-day cardiovascular adverse events were compared between the two groups.Results There were statistical differences in puncture time,operation duration and length of hospital stay between the two groups(P＜0.05,P＜0.01).The brachial artery group had a higher puncture success rate than the radial artery group(94.7％vs 90.7％,P=0.390),while the radial artery group had a higher incidence of postoperative complications,adverse vascular events due to coro-nary heart disease(P＜0.05,P＜0.01).Conclusion Both radial artery approach and brachial artery approach for PCI can effectively treat AMI patients.Compared with transradial approach,transbrachial approach can effectively improve the success rate of surgery,reduce postoperative complications and the occurrence of cardiovascular adverse events within 30 d of follow-up.

Objective:To study the relationship between microRNA (miRNA, miR)-675-3p, miR-675-5p, miR-29b-3p, miR-let-7b-3p and fluoride induced articular cartilage injury in rats.Methods:Using the factorial design, thirty 3-week-old specific pathogen free grade male Wistar rats (weighted 125 - 150 g) were selected and randomly divided into a control group, a 25 mg/L fluoride group, and a 50 mg/L fluoride group using a random number table method, with 10 rats in each group. The control group drank distilled water, while the fluoride exposure groups drank distilled water with fluoride ion concentrations of 25 and 50 mg/L, respectively. Five rats were euthanized in each group at 3 and 6 months of feeding, respectively. Visual observation was used to observe the occurrence of dental fluorosis in rats, and fluoride ion selective electrode method was used to detect the fluoride level in blood, urine, and cartilage. Hematoxylin-eosin staining and safranin O-fast green staining were used to observe the pathological changes of articular cartilage, and Mankin score was used to evaluate the grading of cartilage injury. Real-time fluorescence quantitative PCR was used to detect the expression levels of miR-675-3p, miR-675-5p, miR-29b-3p, and miR-let-7b-3p in cartilage.Results:After 3 and 6 months of fluoride exposure, no dental fluorosis was observed in the control group, while rats in the 25 and 50 mg/L fluoride groups showed varying degrees of dental fluorosis. There were statistically significant differences in the levels of blood fluoride (mg/L: 0.11 ± 0.04, 0.57 ± 0.32, 0.29 ± 0.06, 0.07 ± 0.01, 0.31 ± 0.05, 0.38 ± 0.06), urine fluoride (mg/L: 1.81 ± 0.58, 13.18 ± 2.29, 66.11 ± 20.74, 2.35 ± 1.08, 14.79 ± 3.87, 28.32 ± 4.79), and cartilage fluoride (mg/kg: 341.83 ± 44.07, 612.99 ± 174.72, 991.26 ± 227.32, 338.29 ± 72.53, 957.09 ± 195.86, 1 535.53 ± 89.01) among in rats the control group, 25 mg/L fluoride group, and 50 mg/L fluoride group ( F = 7.76, 42.78, 40.54, 23.10, 18.96, 80.81, P < 0.05). In the 50 mg/L fluoride group, there were statistically significant differences in the levels of urine fluoride and cartilage fluoride of rats exposed for different times ( t = 4.45, - 3.80, P < 0.05). The Mankin score grading for cartilage injury showed that at 3 months of fluoride exposure, there were 4, 0, and 0 rats with normal cartilage in the control group, 25 mg/L fluoride group, and 50 mg/L fluoride group, 1, 4, and 1 rats with mild injury, and 0, 1, and 4 rats with moderate injury, respectively. At 6 months of fluoride exposure, there were 4, 0, and 0 rats with normal cartilage in the control group, 25 mg/L fluoride group, and 50 mg/L fluoride group, 1, 3, and 0 rats with mild injury, 0, 1, and 3 rats with moderate injury, and 0, 1, and 2 rats with severe injury, respectively. Real-time fluorescence quantitative PCR results showed that fluoride exposure dose had individual effects on the expression of miR-675-3p, miR-675-5p, miR-29b-3p, and miR-let-7b-3p in cartilage ( F = 8.68, 7.97, 9.34, 10.14, P < 0.05). There was no individual effect of fluoride exposure time on the expression of miR-675-3p, miR-675-5p, miR-29b-3p, and miR-let-7b-3p in cartilage ( F = 0.00, 0.15, 0.63, 0.53, P > 0.05). However, there was no interaction effect between fluoride exposure time and dose on the above-mentioned miRNA ( F = 0.68, 0.05, 0.22, 0.24, P > 0.05). The correlation analysis results showed that miR-675-3p and miR-675-5p in cartilage were negatively correlated with blood fluoride, urine fluoride, and cartilage fluoride ( r = - 0.37, - 0.42, - 0.56, - 0.53, - 0.57, - 0.53, P < 0.05), while miR-29b-3p and miR-let-7b-3p were positively correlated with urine fluoride and cartilage fluoride ( r = 0.58, 0.40, 0.48, 0.47, P < 0.05). The results of ordered logistic regression analysis showed that miR-675-3p, miR-675-5p, miR-29b-3p, and miR-let-7b-3p were influencing factors of dental fluorosis grading ( OR = 0.13, 0.04, 1.55, 2.58, P < 0.05) and Mankin score grading ( OR = 0.04, 0.06, 1.41, 1.58, P < 0.05). Conclusion:MiR-675-3p, miR-675-5p, miR-29b-3p, and miR-let-7b-3p may be involved in the process of fluoride induced articular cartilage injury.

Aim To explore the mechanism of ligustil-ide(LIG)improving demyelination by inhibiting in-flammatory response in mice with distal middle cerebral artery occlusion(dMCAO)through AIM2/caspase-1 signal pathway.Methods Thirty C57BL/6N male mice were randomly divided into three groups:sham operation group(Sham group,n=10),model group(dMCAO group,n=10)and treatment group(LIG group,n=10).The dMCAO mouse model was estab-lished by electrocoagulation in dMCAO group and LIG group.The mice were scored by Longa after waking up,and the changes of cerebral blood flow were moni-tored by laser speckle blood flow imaging system after dMCAO.One hour after modeling,LIG(30 mg·kg-1·d-1)was injected intraperitoneally in LIG group,and the same amount of normal saline was injected in sham group and dMCAO group for one week until the end of the experiment.The mice in each group were stained with TTC,and the brain injury was observed pathologically.Fatigue turning bar test and open field test were used to evaluate the motor function and anxie-ty degree of mice,and then the brain tissues of mice were taken for black gold staining to compare the chan-ges of myelin sheath in each group.Immunofluores-cence staining was used to detect the average fluores-cence intensity of MBP,IBA1 and GFAP in CC,CPU and CX regions of mouse brains.ELISAwas used to de-tect the contents of TNF-α,IL-6,IL-1 β,IL-17A and BDNF in brain tissue proteins of mice.Western blot-ting was used to detect the protein expressions of AIM2,caspase-1 and ASC-in each group.Results Compared with the dMCAO group,the infarct area was reduced,the behavior was significantly improved and the demyelination was reduced in the LIG group.The expression of MBP protein in CC,CPU and CX regions increased(P＜0.05),the expression of IBA1 in CX decreased(P＜0.01),and the expression of GFAP in-creased in CC,CPU and CX regions(P＜0.01).The results of ELISA showed that the levels ofTNF-α(P＜0.01),IL-6(P＜0.01),IL-1β(P＜0.05)and IL-17A(P＜0.01)significantly decreased,while the ex-pression of BDNF increased(P＜0.05).The protein expression levels of AIM2,caspase-1 and ASC in mouse brain decreased after treatment(P＜0.01).Conclusion LIG has a protective effect on demyelina-tion in dMCAO mice,which may be related to the inhi-bition of AIM2/caspase-1 signaling pathway and in-flammation and to the promotion of BDNF secretion.

Objective To investigate the feasibility and safety of bedside transesophageal echocardiography(TEE)-guided atrial septostomy in patients undergoing extracorporeal membrane oxygenation(ECMO)support.Methods Eight patients(2 females and 6 males)who developed pulmonary edema during VA-ECMO treatment between January 2020 and October 2024 were enrolled.All patients underwent bedside TEE-guided atrial septal puncture,followed by gradual balloon dilation using an Inoue balloon(diameter:18-24 mm).The endpoint for dilation was defined as mean left atrial pressure＜15 mmHg.Post-procedure evaluation included assessment of the septal defect size,mean left atrial pressure,and improvement in bilateral pulmonary edema.Results The mean age of all 8 patients was(43.50±16.84)years old.Atrial septostomy was successfully performed in all patients.The mean balloon dilation diameter was(22.75±2.68)mm,resulting in a mean septal defect size of(6.31±0.37)mm.The mean left atrial pressure significantly decreased from(26.63±1.77)mmHg pre-procedure to(12.75±1.28)mmHg post-procedure(P＜0.001).All patients demonstrated marked improvement in bilateral pulmonary edema,and six patients also showed a significant reduction in the severity of mitral regurgitation following the procedure.No procedure-related complications were observed.Conclusions Bedside TEE-guided atrial septostomy is safe and effective for reducing left heart loading during ECMO support and improving pulmonary edema.

Objective To conduct a cross-sectional study on the relationship between the serum uric acid(sUA)to high density lipoprotein-cholesterol(HDL-C)ratio(UHR)and female infertility.Methods We analyzed data from the National Health and Nutrition Examination Survey(NHANES)2013-2018 cycle,examining 2,963 women aged 18 to 45 years.A multivariable Logistic regression model was used to assess the association between UHR and infertility,adjusting for various confounding factors.The study also explored interactions and dose-response relationships through subgroup analyses and restricted cubic spline(RCS)models,and evaluated the predictive value of UHR for infertility by using receiver operating characteristic(ROC)curve analysis.Results The results showed that the prevalence of infertility was significantly higher among women with elevated UHR.Baseline characteristics revealed that the mean UHR in women with infertility(9.68±4.23)was significantly higher than in those without infertility(8.7±3.81,P<0.001).Multivariable Logistic regression analysis indicated that women in the highest quartile(Q4)of UHR had a significantly increased likelihood of infertility compared to those in the lowest quartile(Q1),with adjusted odds ratios(ORs)ranging from 1.61(95% CI:1.14-2.28)to 1.98(95% CI:1.42-2.78)across different models(P for trend<0.001).Subgroup analyses demonstrated that these associations were consistent across different age groups,body mass index(BMI)categories,and racial groups.The RCS model showed a significant linear dose-response relationship between UHR and infertility risk(nonlinear P=0.03,overall association P<0.001).Additionally,ROC analysis indicated that UHR had a moderate ability to discriminate infertility status,with an area under the curve(AUC)of 0.570.Conclusion A higher UHR is significantly associated with an increased risk of female infertility,and UHR has the potential to serve as a predictive biomarker for the risk of female infertility.

Objective:To investigate the related factors of cognitive impairment in middle-aged and old-aged patients with type 2 diabetes mellitus(T2DM).Methods:A total of 970 patients with T2DM(585 middle-aged group and 385 old-aged group)were selected from residents of a large community in Beijing from September to December 2018.The Mini-Mental State Examination(MMSE)was used to assess the cognitive func-tion.Multivariate logistic regression was used to analyze the related factors.Results:The detection rates of cognitive impairment were 12.0％and 13.5％in middle-aged and old-aged patients with T2DM,respectively.Among mid-dle-aged patients with T2DM,work(OR=0.22,95％CI:0.03-0.77)and education at the junior college or un-dergraduate level and above(OR=0.18,95％CI:0.04-0.55)were protective factors for cognitive impair-ment.Myocardial infarction(OR=4.13,95％CI:1.26-13.63)was a risk factor for cognitive impairment.Among old-aged patients with T2DM,drinking tea 1-2 times a week(OR=0.11,95％CI:0.01-0.58)and education at the junior college or undergraduate level and above(OR=0.19,95％CI:0.05-0.54)were protective factors for cognitive impairment.Stroke(OR=3.64,95％CI:1.55-8.39)and good sleep self-assessment(OR=2.75,95％CI:1.13-7.35)were risk factors for cognitive impairment.Conclusion:Cognitive impairment in middle-aged pa-tients with T2DM is related to work,education level and myocardial infarction,and cognitive impairment in old-aged patients with T2DM is related to lifestyle,education level and stroke.

The control group drank distilled water, while the fluoride exposure groups drank distilled water with fluoride ion concentrations of 25 and 50 mg/L, respectively. Five rats were euthanized in each group at 3 and 6 months of feeding, respectively. Visual observation was used to observe the occurrence of dental fluorosis in rats, and fluoride ion selective electrode method was used to detect the fluoride level in blood, urine, and cartilage. Hematoxylin-eosin staining and safranin O-fast green staining were used to observe the pathological changes of articular cartilage, and Mankin score was used to evaluate the grading of cartilage injury. Real-time fluorescence quantitative PCR was used to detect the expression levels of miR-675-3p, miR-675-5p, miR-29b-3p, and miR-let-7b-3p in cartilage.Results:After 3 and 6 months of fluoride exposure, no dental fluorosis was observed in the control group, while rats in the 25 and 50 mg/L fluoride groups showed varying degrees of dental fluorosis. There were statistically significant differences in the levels of blood fluoride (mg/L: 0.11 ± 0.04, 0.57 ± 0.32, 0.29 ± 0.06, 0.07 ± 0.01, 0.31 ± 0.05, 0.38 ± 0.06), urine fluoride (mg/L: 1.81 ± 0.58, 13.18 ± 2.29, 66.11 ± 20.74, 2.35 ± 1.08, 14.79 ± 3.87, 28.32 ± 4.79), and cartilage fluoride (mg/kg: 341.83 ± 44.07, 612.99 ± 174.72, 991.26 ± 227.32, 338.29 ± 72.53, 957.09 ± 195.86, 1 535.53 ± 89.01) among in rats the control group, 25 mg/L fluoride group, and 50 mg/L fluoride group ( F = 7.76, 42.78, 40.54, 23.10, 18.96, 80.81, P < 0.05). In the 50 mg/L fluoride group, there were statistically significant differences in the levels of urine fluoride and cartilage fluoride of rats exposed for different times ( t = 4.45, - 3.80, P < 0.05). The Mankin score grading for cartilage injury showed that at 3 months of fluoride exposure, there were 4, 0, and 0 rats with normal cartilage in the control group, 25 mg/L fluoride group, and 50 mg/L fluoride group, 1, 4, and 1 rats with mild injury, and 0, 1, and 4 rats with moderate injury, respectively. At 6 months of fluoride exposure, there were 4, 0, and 0 rats with normal cartilage in the control group, 25 mg/L fluoride group, and 50 mg/L fluoride group, 1, 3, and 0 rats with mild injury, 0, 1, and 3 rats with moderate injury, and 0, 1, and 2 rats with severe injury, respectively. Real-time fluorescence quantitative PCR results showed that fluoride exposure dose had individual effects on the expression of miR-675-3p, miR-675-5p, miR-29b-3p, and miR-let-7b-3p in cartilage ( F = 8.68, 7.97, 9.34, 10.14, P < 0.05). There was no individual effect of fluoride exposure time on the expression of miR-675-3p, miR-675-5p, miR-29b-3p, and miR-let-7b-3p in cartilage ( F = 0.00, 0.15, 0.63, 0.53, P > 0.05). However, there was no interaction effect between fluoride exposure time and dose on the above-mentioned miRNA ( F = 0.68, 0.05, 0.22, 0.24, P > 0.05). The correlation analysis results showed that miR-675-3p and miR-675-5p in cartilage were negatively correlated with blood fluoride, urine fluoride, and cartilage fluoride ( r = - 0.37, - 0.42, - 0.56, - 0.53, - 0.57, - 0.53, P < 0.05), while miR-29b-3p and miR-let-7b-3p were positively correlated with urine fluoride and cartilage fluoride ( r = 0.58, 0.40, 0.48, 0.47, P < 0.05). The results of ordered logistic regression analysis showed that miR-675-3p, miR-675-5p, miR-29b-3p, and miR-let-7b-3p were influencing factors of dental fluorosis grading ( OR = 0.13, 0.04, 1.55, 2.58, P < 0.05) and Mankin score grading ( OR = 0.04, 0.06, 1.41, 1.58, P < 0.05). Conclusion:MiR-675-3p, miR-675-5p, miR-29b-3p, and miR-let-7b-3p may be involved in the process of fluoride induced articular cartilage injury.

Aim To explore the mechanism of ligustil-ide(LIG)improving demyelination by inhibiting in-flammatory response in mice with distal middle cerebral artery occlusion(dMCAO)through AIM2/caspase-1 signal pathway.Methods Thirty C57BL/6N male mice were randomly divided into three groups:sham operation group(Sham group,n=10),model group(dMCAO group,n=10)and treatment group(LIG group,n=10).The dMCAO mouse model was estab-lished by electrocoagulation in dMCAO group and LIG group.The mice were scored by Longa after waking up,and the changes of cerebral blood flow were moni-tored by laser speckle blood flow imaging system after dMCAO.One hour after modeling,LIG(30 mg·kg-1·d-1)was injected intraperitoneally in LIG group,and the same amount of normal saline was injected in sham group and dMCAO group for one week until the end of the experiment.The mice in each group were stained with TTC,and the brain injury was observed pathologically.Fatigue turning bar test and open field test were used to evaluate the motor function and anxie-ty degree of mice,and then the brain tissues of mice were taken for black gold staining to compare the chan-ges of myelin sheath in each group.Immunofluores-cence staining was used to detect the average fluores-cence intensity of MBP,IBA1 and GFAP in CC,CPU and CX regions of mouse brains.ELISAwas used to de-tect the contents of TNF-α,IL-6,IL-1 β,IL-17A and BDNF in brain tissue proteins of mice.Western blot-ting was used to detect the protein expressions of AIM2,caspase-1 and ASC-in each group.Results Compared with the dMCAO group,the infarct area was reduced,the behavior was significantly improved and the demyelination was reduced in the LIG group.The expression of MBP protein in CC,CPU and CX regions increased(P＜0.05),the expression of IBA1 in CX decreased(P＜0.01),and the expression of GFAP in-creased in CC,CPU and CX regions(P＜0.01).The results of ELISA showed that the levels ofTNF-α(P＜0.01),IL-6(P＜0.01),IL-1β(P＜0.05)and IL-17A(P＜0.01)significantly decreased,while the ex-pression of BDNF increased(P＜0.05).The protein expression levels of AIM2,caspase-1 and ASC in mouse brain decreased after treatment(P＜0.01).Conclusion LIG has a protective effect on demyelina-tion in dMCAO mice,which may be related to the inhi-bition of AIM2/caspase-1 signaling pathway and in-flammation and to the promotion of BDNF secretion.

Objective To investigate the feasibility and safety of bedside transesophageal echocardiography(TEE)-guided atrial septostomy in patients undergoing extracorporeal membrane oxygenation(ECMO)support.Methods Eight patients(2 females and 6 males)who developed pulmonary edema during VA-ECMO treatment between January 2020 and October 2024 were enrolled.All patients underwent bedside TEE-guided atrial septal puncture,followed by gradual balloon dilation using an Inoue balloon(diameter:18-24 mm).The endpoint for dilation was defined as mean left atrial pressure＜15 mmHg.Post-procedure evaluation included assessment of the septal defect size,mean left atrial pressure,and improvement in bilateral pulmonary edema.Results The mean age of all 8 patients was(43.50±16.84)years old.Atrial septostomy was successfully performed in all patients.The mean balloon dilation diameter was(22.75±2.68)mm,resulting in a mean septal defect size of(6.31±0.37)mm.The mean left atrial pressure significantly decreased from(26.63±1.77)mmHg pre-procedure to(12.75±1.28)mmHg post-procedure(P＜0.001).All patients demonstrated marked improvement in bilateral pulmonary edema,and six patients also showed a significant reduction in the severity of mitral regurgitation following the procedure.No procedure-related complications were observed.Conclusions Bedside TEE-guided atrial septostomy is safe and effective for reducing left heart loading during ECMO support and improving pulmonary edema.
