In recent years,the incidence of differentiated thyroid cancer(DTC)continues to rise,with increasing attention to perioperative management and postoperative thyroid-stimulating hormone(TSH)suppression therapy strategies.The American Thyroid Association(ATA)released the"2025 American Thyroid Association Management Guidelines for Adult Patients with Differentiated Thyroid Cancer"in 2025,which include significant updates on perioperative parathyroid function protection and TSH suppression therapy.In terms of perioperative management,the 2025 ATA guidelines recommend intraoperative application of novel methods to identify and protect the parathyroid glands,and adoption of parathyroid hormone(PTH)-guided calcium and vitamin D supplementation protocols following total thyroidectomy.Regarding TSH suppression therapy,the 2025 ATA guidelines eliminate specific TSH target value recommendations for initial treatment,emphasizing that TSH targets should be dynamically adjusted based on patients'initial recurrence risk and treatment response to achieve individualized management and avoid overtreatment.

Objective:To examine the interaction between interpersonal issues and eating behavior problems among college freshmen, and to identify core psychological factors and potential pathways that drive eating behavior.Methods:In October 2019, a total of 5 073 college freshmen from a university in Shanghai were recruited as participants. Their general demographic data were collected, and they were evaluated using the eating disorder examination questionnaire 6.0 (EDE-Q 6.0) and inventory of interpersonal problems-32(IIP-32).Descriptive analyses were performed using SPSS 24.0 software.A regularized partial correlation network was constructed using the graphical least absolute shrinkage and selection operator (GLASSO) in R(v4.2.3) software. A Bayesian network analysis (BNA) was conducted to build a directed network, aiming to identify core driving factors and key psychological mechanisms.Results:Regularized partial correlation network identified shape concern as the most central node, with the highest strength centrality(1.32) and expected influence(1.20). It showed the highest bridge strength with dominance/control (0.22, 0.21), linking the interpersonal and eating behavior modules. Directed network analysis indicated that low self-confidence was the upstream node influencing social inhibition and cold/ distant relationships, indirectly affecting eating disorder.Within the eating module, shape concern and weight concern predicted eating preoccupation and dietary restraint, forming a pathway structure from eating cognition to behavior.The network demonstrated good stability (CS-coefficient=0.75).Conclusion:Shape concern is the core mechanism underlying eating problems in college freshmen. Low self-confidence contributes indirectly via interpersonal dysfunction. Dominance/control and shape concern bridge interpersonal and eating domains, providing key targets for early prevention and intervention.

Objective To evaluate the efficacy and safety of enteric-coated metformin hydrochloride capsules(Junlida?)in patients with T2DM and poor glycemic control under lifestyle interventions.Methods In this study,419 patients with T2DM were recruited from 15 research centers from July 2020 to March 2022,and randomly divided into observation(Obs)group(n=209)and control group(Con,n=210)using a multicenter,randomized,double-blind,non-inferiority trial design.Patients in the Obs group were treated with enteric-coated Metformin hydrochloride capsules(Junlida?),and patients in the Con group were treated with Metformin hydrochloride tablets(Glucophage?).The optimal effective dose of 2 g/d was achieved within 4 weeks,and the reasonable dose was maintained until the end of treatment.The treatment period was 24 weeks.HbA1c and its compliance rate,FPG,and body weight were compared between the two groups in full analysis set(FAS)and protocol set(PPS).Safety and adverse events(AE)were evaluated in safety set(SS).Results A total of 414 participants were randomized(207 cases in Obs group and 207 cases in Con group).414 cases in FAS population(207 cases in Obs group and 207 cases in Con group),and 328 cases in PPS population(164 cases in Obs group and 164 cases in Con group),and 414 cases in SS population(207 cases in Obs group and 207 cases in Con group).After treatment,HbA1c,FPG and body weight were lower in both groups(P<0.05)in FAS and PPS.HbA1c compliance rate was not significantly different between the two groups in FAS and PPS(P>0.05).The results of non-inferiority test showed that the lower limit was>-0.4%in both FAS(-0.154,95%CI-0.384～0.069)and PPS(-0.139,95%CI-0.390～0.112),and the Obs group reached non-inferiority end point.The achievement rate,compliance rate,safety index and incidence of AE were not significantly different between the two groups(P>0.05).Conclusions Junlida? demonstrated non-inferiority to Glucophage? in glycemic control and can be safely and effectively used in patients with diabetes.

The incidence of generalized anxiety disorder(GAD)has recently been increasing year by year,in a complex social environment.The diagnosis of GAD currently often relies on DSM-5 and ICD-10 criteria,which include subjectivity and limitations.Understanding the intrinsic activity of brain network functions and structural connectivity is an important goal of contemporary neuroscience research.Electroencephalographic microstates are capable of observing broad frequency components and capturing dynamic changes in brain activity,thus providing a novel perspective on the accuracy of GAD diagnosis.This review considers the electroencephalographic microstate features and explores the abnormalities in the functional brain network in patients with GAD,with the aim of providing a clear diagnosis,optimizing the therapeutic efficacy,and improving the quality of medical care for patients with GAD.

Objective:To explore the effect and possible mechanism of Semen euryales mixture(QSHJ)on renal injury in lu-pus nephritis.Methods:The 14-week-old C57BL/6 mice were the control group of 8.The 14-week-old MRL/lpr mice were randomly di-vided into model group,QSHJ low,medium and high doses groups(7.48,14.95,29.90 g/kg),and prednisone group(5 mg/kg)of 8 mice each.The control group and the model group were given the same volume of normal saline by gavage once a day for 4 weeks.Urine was collected to detect urinary protein content.HE and PASM staining were used to observe renal tissue injury.The serum levels of Anti-dsDNA,IL-6 and TNF-α were detected by ELISA.The protein expressions of phosphatidylinositol 3-kinase(PI3K),phosphor-ylated PI3K(p-PI3K),protein kinase B(AKT),phosphorylated AKT(p-AKT),nuclear factor kappa B p65(NF-κB p65)and phos-phorylated NF-κB p65(p-NF-κB p65)were detected by Western blot.The protein expressions of PI3K,p-PI3K,AKT and p-AKT were detected by immunohistochemistry.The positive expression of NF-κB p65 was observed by immunofluorescence.Results:Com-pared with the control group,the urinary protein content in the model group increased significantly(P<0.05),the renal tissue was in-filtrated with inflammatory cells,and the tissue structure was destroyed obviously,the contents of Anti-dsDNA,IL-6 and TNF-α in se-rum were significantly increased(P<0.05),the expressions of p-PI3K/PI3K,p-AKT/AKT and p-NF-κB p65/NF-κB p65 were signifi-cantly increased(P<0.05),the protein expressions of p-PI3K and p-AKT were increased significantly(P<0.05),the positive expres-sion of NF-κB p65 was increased significantly.Compared with the model group,the urinary protein content of QSHJ low,medium and high doses groups and prednisone group decreased significantly(P<0.05),the infiltration of inflammatory cells in renal tissue was re-lieved,and the damage of tissue structure was alleviated.the contents of Anti-dsDNA,IL-6 and TNF-α in serum were significantly de-creased(P<0.05),the expressions of p-PI3K/PI3K,p-AKT/AKT and p-NF-κB p65/NF-κB p65 were significantly decreased(P<0.05),the protein expressions of p-PI3K and p-AKT were significantly decreased(P<0.05),the positive expression of NF-κB p65 flu-orescence was decreased.Conclusion:QSHJ can improve the pathological manifestations of renal tissue in MRL/lpr mice and alleviate the disease process.The mechanism may be related to the inhibition of PI3K-AKT/NF-κB signaling pathway in renal tissue and the re-duction of inflammatory response by QSHJ.

Corneal endothelial decompensation is a condition caused by a decline in corneal endothelial cells (CECs) density below a critical threshold, leading to corneal edema, clouding, and impaired vision.CECs have minimal regenerative capacity in the human body and gradually decrease in number with age.When affected by pathological factors such as inflammation, trauma or infection, irreversible damage can occur.Traditional treatments include penetrating keratoplasty and posterior lamellar endothelial keratoplasty.However, their application in clinical practice is limited due to problems such as donor shortage, postoperative complications and technical challenge.In recent years, with advances in the understanding of CECs biology and corneal transplantation techniques, emerging approaches such as cell therapy (including cell injection and tissue-engineered endothelial grafts), pharmacological interventions (such as ROCK inhibitors and anti-oxidative stress drugs), and gene therapy (such as CRISPR/Cas9 and RNA interference) have been developed.This review summarizes both traditional and emerging treatments for corneal endothelial decompensation, comparing their advantages and limitations in terms of surgical method, cell source, pharmatheutical therapy, and gene-targeting strategy, and discusses future development trends to provide theoretical support for clinical treatment and research.

Objective:Analyze the risk factors of gastrointestinal perforation caused by foreign body and summarize the experience of surgical treatment of foreign bodies.Method:From Jan 2008 to Dec 2023, 89 patients with foreign bodies in the digestive tract were admitted to the Department of Gastrointestinal Surgery, Peking University First Hospital. Relevant data were collected and binary logistic regression was used to analyze the independent risk factors for intestinal perforation, resection and anastomosis of intestine or enterostomy/colostomy.Results:The mean age of 89 patients was (60.1±16.2) years old, 65 patients (73%) had unintentionally ingested foreign bodies. The most common foreign bodies were jujube pits (40 cases). Thirty-nine patients diagnosed with gastrointestinal perforation. Binary Logistic regression analysis showed that the total number of leukocytes ( OR=4.085, 95% CI: 1.214-13.745, P=0.023), sharp foreign body ( OR=26.124, 95% CI: 5.194-131.392, P<0.001), and the location of foreign body ( OR=3.980, 95% CI: 1.178-13.465, P=0.026) were the independent risk factors for gastrointestinal perforation. Thirty-three patients underwent gastrointestinal repair surgery, and 36 patients underwent resection and anastomosis of intestine or enterostomy/colostomy. Binary Logistic regression analysis showed that the foreign body located in the colorectum ( OR=71.928, 95% CI: 4.646-1 113.479, P=0.002) and the length of the foreign body ≤2.5 cm ( OR=5.791, 95% CI: 1.606-20.882, P=0.007) were the independent risk factors for resection and anastomosis of intestine or enterostomy/colostomy. Conclusions:Leukocyte count ≥10×10 9/L, sharp foreign body, and location of foreign body are independent risk factors for gastrointestinal perforation. Foreign body located in the colorectum and foreign body length ≤2.5 cm are risk factors for resection and anastomosis of intestine or enterostomy/colostomy.
