Lung cancer is the leading type of cancer death, and most patients with lung cancer are diagnosed at an advanced stage and have a very poor prognosis. Although low-dose computed tomography (LDCT) has entered the clinic as a screening tool for lung cancer, its false-positive rate is more than 90%. As one of the epigenetic modifications of research hotspots, DNA methylation plays a key role in a variety of diseases, including cancer.Hypermethylation of tumor suppressor genes and hypomethylation of proto-oncogenes are important events in tumorigenesis and development. Therefore, DNA methylation analysis can provide some useful information for the early screening, diagnosis, treatment and prognosis of lung cancer. Although invasive methods such as tissue biopsy remain the gold standard for tumor diagnosis and monitoring, they also have limitations such as inconvenience in sampling. In recent years, there has been a rapid development of liquid biopsy, which can detect primary or metastatic malignancies and reflect the heterogeneity of tumors. In addition, the blood sample can be collected in a minimally invasive or non-invasive format and is well tolerated in older and frail patients. This article explores some of the emerging technologies for DNA methylation analysis and provides an overview of the application of DNA methylation in the diagnosis and treatment of lung cancer.

Objective:Evaluate the safety and efficacy of aortic endovascular remodeling device (AERD) in the treatment of residual aortic dissection on Stanford type B aortic dissection patients after endovascular repair.Methods:Adopting a prospective cohort study design, according to the inclusion and exclusion criteria, a total number of 60 patients with Stanford B-type aortic dissection after TEVAR surgery from January 2022 to December 2023 were included. Collecting CTA imaging data of patients before and after endovascular treatment with AERD and using computer 3D reconstruction fluid dynamics to evaluate distal aortic remodeling.Results:The incidence of major adverse events and mortality rate associated with aortic dissection within 30 days were 0 after endovascular treatment with AERD. In the short term, AERD was safe for the treatment of residual aortic dissection on Stanford type B aortic dissection patients after endovascular repair. Endovascular treatment with AERD significantly increased the volume of the true lumen of the aorta in the dissection segment, with an increase of 88.44%. At the same time, endovascular treatment with AERD significantly reduced the volume of the false lumen of the aorta in the dissection segment, with a decrease of 61.04%. Endovascular treatment with AERD has no significant effect on the longest true lumen diameter of distal aorta of stent and upper margin aorta of superior mesenteric artery. Comparing to the longest diameter of the true lumen of the aorta, the change in the shortest diameter of the true lumen of the aorta is more significant, with the shortest diameter of true lumen of distal aortic of the stent increasing by 32.29%, the shortest diameter of true lumen of the narrowest part of the aorta increasing by 204.15%, the shortest diameter of true lumen of the upper margin aorta of superior mesenteric artery increasing by 80.76%, the shortest diameter of true lumen of the lower edge aorta of the renal artery increasing by 115.26%, the shortest diameter of the opening of the left iliac artery increasing by 152.01%, and the shortest diameter of opening of the right iliac artery increasing by144.21%.Conclusion:AERD is safe and effective in the treatment of residual aortic dissection on Stanford type B aortic dissection patients after endovascular repair. Endovascular treatment with AERD promotes true lumen dilation and false lumen reduction in the early postoperative stage and promotes benign remodeling of the distal aorta after TEVAR surgery.

Background and purpose:With the aging population,the number of elderly patients with colorectal cancer(CRC)is increasing.To date,elderly patients with stage Ⅱ CRC often receive a weakened chemotherapy regimen or even no chemotherapy after radical surgery,and It is still unclear whether this will lead to adverse oncological outcomes.This study aimed to explore the prognostic impact of advanced age on stage Ⅱ CRC patients after removing bias through a multivariate COX regression approach.Methods:We retrospectively collected data of 3314 colorectal cancer patients with postoperative pathology of stage Ⅱ,no history of previous tumors,no secondary primary tumors within 5 years after surgery and no preoperative neoadjuvant therapy.This study was reviewed by the medical ethics committee of Fudan University Shanghai Cancer Center(ethics number:050432-4-2108*).The optimal threshold for calculating age relative to survival using survminer package of R software(version 3.0)(surv_cutpoint algorithm)was 73 years.We compared the clinical and pathological characteristics,overall survival(OS)and disease-free survival(DFS)between the older group(age＞73 years)and the younger group(age≤73 years).The alignment diagram prediction model was drawn using the survival package and RMS package.Results:The elderly and non-elderly groups were evenly comparable in terms of gender,tumor location,differentiation,vascular invasion,perineural invasion and pT stage.Multivariate COX regression showed that advanced age was an independent prognostic risk factor for OS[hazard ratio(HR)=3.725(3.051-4.549),P＜0.001]and DFS[HR=2.431(2.029-2.912),P＜0.001].The nomogram(alignment diagram)prediction model constructed based on multivariate COX regression could effectively evaluate the prognosis of stage Ⅱ CRC patients and provide guidance for practical clinical work.Conclusion:In stage Ⅱ CRC patients,older age is associated with shorter OS and DFS.Adequate intensity of adjuvant chemotherapy may be necessary.Treatment decisions can be adjusted based on the predicted model scores of the patient's alignment diagram.

Background and purpose:According to current consensus,adverse high-risk pathological features are only associated with adjuvant therapy for stage Ⅱ colorectal cancer(CRC).As important prognostic factors,we further explored the possibility of identifying patients with potential recurrence and poor prognosis based on these incorporating high-risk pathological features.Methods:This is a cohort study.A retrospective analysis was conducted on clinical data of CRC patients who underwent surgical treatment at the Second Department of Colorectal Surgery,Fudan University Affiliated Shanghai Cancer Center from 2008 to 2018.This study was approved by the Ethics Committee of the Fudan University Shanghai Cancer Center(approval No.:050432-4-2108*),and the study complies with the Declaration of Helsinki.A total of 9875 patients were enrolled,including 5859 males and 4016 females,aged[M(IQR)]60(16)years(range:16 to 94).Median follow-up time was 1779.0 days[95%CI:1750.1-1807.9].We used the Kaplan-Meier method to plot survival curves for different groups.Cox multivariate analysis was used to identify independent risk factors for 5-year overall survival(OS),disease-free survival(DFS)and recurrence-free survival(RFS).Finally,a column chart model was constructed to evaluate and stratify patient prognosis.The Strengthening the Reporting of Observational Studies in Epidemiology(STROBE)checklist was followed for this cohort study.Results:According to the number of incorporating high-risk pathological features,patients were divided into five groups:Hr_0 group(0 incorporating high-risk pathological feature),Hr_1 group(1 incorporating high-risk pathological feature),Hr_2 group(2 incorporating high-risk pathological features),Hr_3 group(3 incorporating high-risk pathological features),and Hr_4 group(4 or more incorporating high-risk pathological features).The Kaplan-Meier survival curve results indicated significant differences in OS,DFS and RFS among different groups(all P<0.001).Subgroup analysis was conducted on stage Ⅱ colorectal cancer,and the survival curves of OS,DFS and RFS in different Hr groups overlapped with each other.Compared to the overall population,the survival differences in different groups were significantly reduced,indicating that stage Ⅱ colon cancer patients with incorporating high-risk pathological features may benefit from adjuvant chemotherapy.The independent prognostic factors for RFS included age,pT stage,pN stage and Hr group.The survival curves of OS,DFS and RFS indicated that the prognosis of Hr_4 group was significantly worse than that of stage Ⅲc patients;5.2%and 14.1%of stage Ⅰ and Ⅱ patients had two or more incorporating high-risk pathological features(Hr group≥2),respectively.Finally,a column chart model was constructed by incorporating the independent prognostic risk factors for CRC mentioned above.The calibration curve showed a good consistency between the actual observations and the predictions made by the nomogram,and the decision curve analysis(DCA)indicated that the model constructed in this study had good efficacy in stratifying recurrence.Conclusion:The number of incorporating high-risk pathological features is an independent prognostic factor for RFS in patients with stage Ⅰ-ⅢCRC.Combining it as a multiclass variable with age,pT and pN stage has good prognostic stratification and recurrence stratification efficacy,which is expected to guide clinical treatment.

IU plays an important role in the occurrence and development of anxiety， but the specific process and mechanism remain unclear. This paper reviews the influence of IU on anxiety， and clarifies its mechanism of action on the generation and development of anxiety from the perspectives of cognition， emotion and behavior， so as to provide references for preventing the development of general anxiety into anxiety disorders and developing new psychological intervention and treatment strategies.

Levothyroxine is a class of thyroid hormone medication mainly used in the clinical treatment of thyroid hormone replacement therapy and thyrotropin suppression therapy. In recent years, studies have found a close correlation between the human gut microbiota and the occurrence and development of thyroid diseases, as well as changes in thyroid hormone levels. Therefore, understanding the impact of levothyroxine on the gut microbiota, as well as the effects of the gut microbiota on the metabolism and absorption of levothyroxine, is of great significance for the treatment of thyroid diseases and the rational use of clinical medication. This article explores the interaction between the gut microbiota and levothyroxine and summarizes the current clinical findings of the gut microbiota in levothyroxine therapy.
