Radiofrequency ablation (RFA) is a minimally invasive treatment modality used as an alternative to surgery in patients with benign thyroid nodules, recurrent thyroid cancers (RTCs), and primary thyroid microcarcinomas. The Korean Society of Thyroid Radiology (KSThR) initially developed recommendations for the optimal use of RFA for thyroid tumors in 2009 and revised them in 2012 and 2017. As new meaningful evidence has accumulated since 2017 and in response to a growing global interest in the use of RFA for treating malignant thyroid lesions, the task force committee members of the KSThR decided to update the guidelines on the use of RFA for the management of RTCs based on a comprehensive analysis of current literature and expert consensus.

PURPOSE: Three-dimensional (3D) printing must go through a post-processing procedure. This study aimed to evaluate the effects of different cleaning methods on 3D printed three-unit fixed partial dentures using 3D analysis. MATERIALS AND METHODS: A three-unit fixed partial denture was designed and printed using two different printers. The evaluation was taken regarding cleaning method with ethanol (ETH) or isopropanol (IPA), and combining ultrasonic (US) technique for the following groups: group 1, ETH; group 2, ETH+US; group 3, IPA; group 4, IPA+US; and group 5, US. The 3D evaluation was conducted by calculating the mean distance between two specific points and analyzing various angular deviations, utilizing the geometry-embedded library. In addition, visual analysis was performed by creating sectional planes in different points of view. Normality test and independent t-test were performed to compare results between the two printers used in this study. In addition, one-way ANOVA was performed to compare cleaning method groups. RESULTS: Mean distance results showed statistical differences between printers for groups IPA, US, and IPA+US, whereas no significant differences were found among cleaning methods. Angular measurements were taken at the bucco-lingual, proximal, and occlusal planes to assess deviations in the internal surfaces. Overall results showed a tendency of shrinkage of the printed three-unit fixed partial denture. CONCLUSION Ultrasonic treatment may impact the washing efficiency when used with other cleaning solutions regarding angular and longitudinal deformation. Adequate selection of post-processing methods is crucial to decrease morphological deformities in 3D printed materials.

Aim To predict and verify the potential mechanism of the compatibility of"ginseng-astragalus-pueraria"in protecting islet morphology and improving insulin resistance by using network pharmacology.Methods The active ingredients and targets of the horn medicine were obtained from three platforms:TC-MSP,TCMIP,and BATMAN.The targets of type 2 dia-betes mellitus(T2DM)were obtained from three plat-forms:TTD,OMIM,and disgeNET.The PPI network was constructed by using the STRING database and Cy-toscape 3.9.1;GO and KEGG analysis were per-formed;POCASA 1.1 was used to predict protein binding sites,and AutoDock Vina1.1.2 was used for docking and experimental verification.Results"Gin-seng-astragalus-pueraria"screened out 2 021 targets,of which 152 were closely related to T2DM,and 10 key genes and the AGE-RAGE signaling pathway were i-dentified.Molecular docking showed that quercetin had good binding to RAGE,INS,and PI3K.Experi-ments showed that the horn drug increased insulin binding rate and secretion index and reduced serum in-sulin level and insulin resistance index.These data benefited from"ginseng-astragalus-pueraria"reducing the expression of AGE-RAGE,activating PI3K-Akt,in-hibiting NF-κB,and reducing the expression of IL-6,IL-1β and TNF-α.Conclusion The study suggests that"ginseng-astragalus-pueraria"regulates the AGE-RAGE/PI3K-Akt/NF-κB signaling pathway,repairs damaged islet morphology,and improves insulin resist-ance.

As guideline for perioperative pain management in patients undergoing abdominal surgery(2025 edition) was published,pain management has encompassed a more standardized and accurate mode. This interpretation has an important guidance for pain management team to understand clinical practice methods and strategy better.The interpretation made a more detailed analysis of analgesic interventions and non-pharmacological strategies in multimodal analgesia.

Objective:To investigate the current status of the implementation of home-based phototherapy (HBPT) in patients with vitiligo, and to analyze management needs among patients receiving HBPT.Methods:A questionnaire survey was conducted on the application of HBPT among patients with vitiligo who visited the outpatient clinic of the Hospital for Skin Diseases, Chinese Academy of Medical Sciences from December 2021 to November 2022. Additionally, the popularization and usage of HBPT as well as needs of patient management were investigated and analyzed in these vitiligo patients.Results:A total of 496 valid questionnaires were collected from 496 patients with vitiligo (241 males [48.5%] and 255 females [51.5%]) . Their ages at visit ranged from 2 to 67 (30.87 ± 12.36) years. The most commonly affected sites were the head and face (52.2%) , followed by hair (32.1%) , hands and feet (31.4%) , trunk (30.2%) , limbs (24.3%) , neck (19.5%) , and perineum (9.9%) . Among the participants, 320 (64.5%) were currently using or had used HBPT, and 352 (70.8%) expressed a willingness to learn more about HBPT usage guidelines and health education. Regarding the repigmentation outcomes after HBPT: among 312 patients, 54 (17.3%) reported complete recovery, 64 (20.5%) were markedly improved, 142 (45.5%) experienced improvement, and 52 (16.7%) showed no response. Adverse reactions occurred in 223 patients (71.5%) , of whom 28 (9.0%) experienced severe adverse reactions. The most desired guiding information was the adjustment method for phototherapy dosage and treatment duration (184/352, 52.3%) ; the most effective way to receive health education information was through verbal education by medical staff (177/352, 50.3%) .Conclusion:For vitiligo patients who were willing to accept and use HBPT, the most desired guiding information was the adjustment method for phototherapy dosage and treatment duration, and verbal health education by medical staff appeared to be the main way to obtain health education information.

Objective:To observe the clinical efficacy of against-lateral correction Tuina(Chinese therapeutic massage)in treating atlanto-axial joint disorder(AAJD)and imaging changes.Methods:A total of 142 patients with AAJD were recruited.They were randomly allocated to a trial group and a control group using the random number table method,with 71 participants in each group.The trial group was treated with against-lateral correction Tuina 3 times weekly.The control group was offered conventional physical traction therapy once daily.The interventions lasted 2 weeks in both groups.The two groups of participants were observed before and after treatment for their changes in the global pain scale(GPS)score,visual analog scale(VAS)score for dizziness assessment,cervical range of motion(ROM)in rotation,and the extent of atlanto-dental displacement.Results:The GPS and VAS scores dropped after treatment in both groups(P<0.05)and were lower in the trial group than in the control group after treatment and at the follow-up(P<0.05).Participants in the trial group achieved a significant increase in the cervical ROM in rotation after treatment and at the follow-up compared to the pre-treatment value(P<0.05)and surpassed the control group(P<0.05);the control group only showed an increase in the left-side rotation(P<0.05).After the intervention,neither the intra-group nor the between-group comparison revealed significant differences in the extent of atlanto-dental displacement(P>0.05),though the trial group presented an improving tendency.Conclusion:Compared to physical traction,the against-lateral correction Tuina method works more significantly in improving pain,dizziness,and ROM in AAJD patients.
