ObjectiveTo investigate the therapeutic effect of Siegesbeckiae Herba water decoction （SWD） at different doses on atherosclerosis （AS） in a mouse model induced by a high-fat diet and analyze its potential mechanism of action. MethodsThirty-six male ApoE^-/- mice were randomly divided into six groups： blank control group， model group， low-dose， medium-dose， and high-dose SWD groups， and positive control group. Firstly， the AS mouse model was created by feeding mice a high-fat diet. After successful modeling， the low-， medium-， and high-dose SWD groups were intragastrically administered with SWD at 0.65， 1.3， 2.6 g·kg^-1， respectively. The positive control group was intragastrically administered with 30 mg·kg^-1 of atorvastatin calcium aqueous solution， while the blank and model groups received an equal volume of 0.9% sodium chloride solution via oral gavage， all administered for 12 weeks. During the administration period， the general condition of the mice was observed and recorded daily. Before sampling， color Doppler ultrasound was performed to observe the pathological changes in atherosclerotic plaques in the aortic wall of mice. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in aortic tissue in mice， and oil red O staining was used to detect the atherosclerotic plaque area in the aorta. Enzyme-linked immunosorbent assay （ELISA） was used to detect the serum lipid indices and the levels of interleukins （IL-1β， IL-4， IL-6， and IL-10） and tumor necrosis factor-α （TNF-α） in mice. Protein expression levels of IKKα， IKKβ， and NF-κB p65 in mouse aortic tissue were detected by Western blot. ResultsCompared with the blank control group， the model group showed a significant increase in body weight. The results of color Doppler ultrasound showed enhanced vascular wall echo， suggesting the presence of atherosclerotic plaques. HE staining showed foam cell aggregation， fibrous connective tissue proliferation， and vascular intima injury in the aortic tissue. Oil red O staining showed a significant increase in the plaque area in the aortic tissue （P<0.01）. ELISA results indicated significantly elevated levels of IL-1β， IL-6， TNF-α， total cholesterol （TC）， triglyceride （TG）， and low-density lipoprotein （LDL） in mouse serum （P<0.01）， as well as significantly decreased levels of IL-4， IL-10， and high-density lipoprotein （HDL） （P<0.01）. Western blot results showed that the expression of IKKα， IKKβ， and NF-κB p65 in mouse aortic tissue increased significantly （P<0.01）. Compared with those in the model group， mice in the middle- and high-dose SWD groups showed significant weight loss. In the high-dose group， the aortic vascular wall echoes were weakened， and the atherosclerotic plaques were reduced. The aortic lesions of mice in the medium- and high-dose SWD groups were significantly alleviated. The plaque area percentage showed an inverse correlation with the administered dose in all groups treated with SWD （P<0.05）. In the medium-dose SWD group， serum levels of IL-1β， IL-6， TNF-α， TC， TG， and LDL were significantly decreased （P<0.05， P<0.01）， while those of IL-4 and IL-10 were significantly increased （P<0.01）. In the high-dose SWD group， levels of IL-1β， IL-6， TNF-α， TC， TG， and LDL were significantly decreased （P<0.01）， while IL-4， IL-10， and HDL were significantly increased （P<0.01）. The IKKα and IKKβ expression was significantly decreased in the low-dose SWD group （P<0.05）， and IKKα， IKKβ， and NF-κB p65 were significantly decreased in the medium- and high-dose SWD groups （P<0.05， P<0.01）. ConclusionSWD may exert therapeutic effects on AS by regulating the expression of related inflammatory factors through the NF-κB signaling pathway， thereby reducing inflammation， plaque area， and lipid content in the body.

Objective:To report a case of pediatric infected maxillary mucocele and review relevant literature. Methods:A 3 years and 9 months old male patient was involved. He had nasal congestion and runny nose for 3 months. He usually has pus and occasional bloody nose. Physical examination: A red lump in the right nasal cavity with complete obstruction of the nasal passage. CT and MRI showed a right sinus mass. The patients WBC was 4.76×10⁸, and CRP<0.5 mg/L. Drainage and marsupialization were performed by endoscopy. Results:No purulent discharge was observed during follow-up, and the recovery was good. Conclusion:Enhanced CT or MRI shows typical circular enhancement shadows in infected maxillary mucocele. This indicates that endoscopic sinus surgery has a definite therapeutic effect. Drainage and marsupialization of maxillary mucocele are sufficient.

Objective:To explore the clinical manifestations, recurrence factors, and outcomes of revision surgery for recurrent thyroglossal duct cysts and fistulas in children. Methods:A retrospective study was conducted on the clinical manifestations, the relationship between cysts/ fistulas and residual hyoid bone of 10 patients with recurrent thyroglossal cysts and fistulas admitted to our hospital from July 2015 to July 2023, as well as the methods and effects of revision surgery. Results:The recurrence time after the initial surgery was between 7 months and 6 years, with an average of 2 years and 1 month.Clinical manifestations: 50%（5 cases） of patients have recurrent cysts near the incision, 40%（4 cases） had recurrent infections at the incision and eventually form fistulas, and 10%（1 case） experienced sleep snoring and pharyngeal trouble, were diagnosed with lingual thyroglossal duct cyst through laryngoscopy. All cysts or fistulas are connected to residual hyoid bodies, and three cases have intact hyoid bodies.Revision surgery: Nine cases underwent modified Sistrunk surgery, removing cysts, fistulas, and residual hyoid bodies. Suspension laryngoscopy and coblation were employed to treat the lingual thyroglossal duct cyst. After the revision surgery, follow-up was conducted for 8 months to 3 years, and no recurrence was found. Conclusion:All recurrences of thyroglossal duct cysts in this study were associated with residual hyoid bodies. Therefore, for thyroglossal duct cysts or fistulas, whether it is the first surgery or a revision surgery, it is recommended to choose the optimized Sistrunk operation, with the key point being complete resection of the hyoid body. Cases with lingual thyroglossal duct cyst can be treated with suspension laryngoscopy by coblation. Whether to remove the residual hyoid body requires further observation.

Objective:To explore the clinical efficacy of the coblation resection of lingual thyroglossal duct cysts under self-retaining laryngoscopy. Methods:A retrospective analysis was conducted on the clinical data of 22 patients with lingual thyroglossal duct cysts admitted to our hospital from December 2016 to December 2023. There were 16 males and 6 females, aged 2 years to 12 years and 3 months（mean: 4 years 1 month; median: 3 years 3 months）. The lingual thyroglossal duct cysts were removed by coblation under self-retaining laryngoscopy. If the cysts could not be removed completely, the epithelial cells of the remaining cysts would be ablated. Results:There were 22 cases of lingual thyroglossal duct cysts，13 cases （59.1%） of lingual thyroglossal duct cysts had laryngeal stridor and dyspnea. The postoperative follow-up period is 3 months to 7 years. 11 cases （50.0%） underwent secondary laryngoscopic evaluation.There were 4 cases of recurrence （18.2%）, with no laryngeal obstruction,bleeding, or nerve damage. Conclusion:Laryngeal stridor and dyspnea are the main clinical symptoms of lingual thyroglossal duct cysts in children. The coblation resection of lingual thyroglossal duct cysts under self-retaining laryngoscopy is safe and effective. Cyst recurrence correlates strongly with residual cyst walls, emphasizing the need for enhanced intraoperative visualization and refined surgical precision.

Objective To investigate the biomechanical effects of implant-anchored retraction and intrusion of maxillary anterior teeth under different force systems using three-dimensional finite element analysis(3D-FEA),by constructing models simulating both normal periodontium and mild alveolar bone resorption.Methods Cone-beam computed tomography(CBCT)data from a patient with skeletal protrusion and gummy smile was utilized.3D finite element models integrating micro-implants anchorage(MIA)and a straight-wire ap-pliance for en-mass retraction of maxillary anterior teeth were established using Mimics,Geomagic,SolidWorks,and Ansys software.Six experimental groups were designed based on alveolar bone height and vertical positioning of posterior MIA.Groups A1,A2,A3:Normal alveolar bone height.Groups B1,B2,B3:Mild alveolar bone resorption.Posterior MIA were placed between the first molar and second premolar at vertical heights of 4,6,and 8 mm(relative to the cementoenamel junction),respectively,each loaded with 200 g retraction force.Anterior MIA between the central and lateral incisors delivered 50 g intrusion force.Stress distribution,anterior tooth displacement patterns,and torque changes were analyzed and compared across all groups.Results Under varying force conditions,greater torque loss was observed in the anterior teeth of the mild alveolar bone resorption group compared to the periodontally healthy group.Differential displacement patterns emerged among central incisors,lateral incisors,and canines when posterior MIA were placed at different vertical heights.The center of resistance in the resorption group shifted apically,resulting in undesirable extrusion and com-promised torque control during intrusion-retraction of maxillary anterior teeth.Conclusion Anterior torque control is more challenging in the alveolar bone resorption group than in the periodontally normal group.Elevating posterior MIA height promotes bodily movement of central incisors,thereby mitigating the ＂bowing effect＂ to a clinically relevant extent.

Post-stroke cognitive impairment (PSCI) is a common complication after stroke, which has high disability rate and mortality rate, and can affect the patient′s daily living ability and quality of life. Non-invasive brain stimulation (NIBS) has the advantages of non-invasiveness, safety, and ease of operation, and is easily accepted by patients. NIBS has a good application prospect in the treatment of PSCI, especially the representative treatment repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) such as have good clinical application effects. At present, there is no standardized treatment plan for NIBS, and there are large individual differences in therapeutic effects. This study reviewed the mechanism and clinical application of NIBS in the treatment of PSCI, and discussed the future application direction of NIBS.

Alzheimer's disease(AD)is the most prevalent form of cognitive impairment.Alongside common cognitive deficits, neuropsychiatric symptoms, and compromised daily activities, a growing body of research indicates that AD patients exhibit various forms of motor dysfunction, such as eye movement, upper limb movement, and gait and balance issues, even in the early stages, including the prodromal and preclinical phases of AD.This article introduced the presentation of motor dysfunction, its correlation with cognitive impairment and AD biomarkers, with the aim of aiding in the early detection, diagnosis, and treatment of AD.
