Objective:To explore the therapeutic effect of compound Kuijie Ankang Decoction on ulcerative colitis (UC) model mice by non targeted metabonomics; To explore its mechanism.Compound Kuijie Ankang.Methods:The mice were randomly divided into blank control group, model group, Kuijie Ankang Decoction group and sulfasalazine group, with 12 mice in each group. Except the blank control group, the other groups were given 1.5% DSS solution for free drinking to prepare UC model. After successful modeling, Kuijie Ankang Decoction group was intragastrically administered with compound Kuijie Ankang Decoction of 9.68 g/kg, sulfasalazine group was intragastrically administered with sulfasalazine capsule suspension of 320 mg/kg, model group and blank control group were intragastrically administered with equal volume of purified water, once a day, for 7 consecutive days. The body mass and disease activity index (DAI) score of mice were measured. ELISA was used to measure the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), and interleukin-10 (IL-10) in the colon tissue of mice; the protein expressions of Claudin-1 and Zo-1 in colon tissue were detected by immunofluorescence method. HE staining was used to observe the pathological changes in the colon, and UHPLC-OE-MS technology was used to analyze the endogenous metabolite structure of mouse colon tissue, differential metabolites and related metabolic pathways were screened.Results:Compared with the model group, the colon length in Kuijie Ankang Decoction group and sulfasalazine group increased ( P<0.01), the DAI score decreased ( P<0.01), the levels of TNF-α, IL-1β and IL-6 in colon tissue decreased ( P<0.01), the level of IL-10 increased ( P<0.01), and the average optical density of Claudin-1 and Zo-1 protein increased ( P<0.01 or P<0.05). Metabolomics analysis identified 26 potential differential metabolites, including nicotinamide adenine dinucleotide, guanine, gamma aminobutyric acid, and thiamine, affecting 26 key metabolic pathways, including lysine biosynthesis, thiamine metabolism, cysteine and methionine metabolism. Conclusion:Kuaijie Ankang Decoction may improve metabolites such as Gamma aminobutyric acid and thiamine through metabolic pathways such as lysine biosynthesis to alleviate inflammatory reactions, thereby exerting therapeutic effects on ulcerative colitis in mice.

The development and validation of clinical prediction models based on artificial intelligence (AI) and machine learning methods have become increasingly widespread. However, the prediction model bias risk and applicability evaluation tool developed in 2019 (i.e., PROBAST-2019) has shown significant limitations. Therefore, an expanded and updated version of the PROBAST-2019 tool was released in 2025, known as the PROBAST+AI tool. The tool is divided into two parts including model development and model evaluation. It aims to comprehensively and systematically evaluate potential methodological quality issues in model development, bias risks in model evaluation, and the applicability of models, regardless of the modeling method used. This paper provides a systematic interpretation of the PROBAST+AI tool's items and case analyses, with the aim of guiding and assisting researchers engaged in related studies and promoting the high-quality development of clinical predictive model research.

Objective:To investigate the association between fibroblast growth factor 21(FGF21)and chronic kidney disease(CKD)in a prediabetic population by conducting a 4-year prospective cohort study among community-dwelling residents aged≥40 years in Guangzhou,China.Methods:A total of 1505 subjects who met the criteria for prediabetes and had complete baseline data were col-lected from the 2012 REACTION cohort,and they were followed up for 4 years to observe newly-onset CKD and the changes in urinary albumin-to-creatinine ratio(UACR)and estimated glomerular filtration rate(eGFR).Results:Among the 1 505 subjects with predia-betes,142 reached the diagnostic criteria for CKD during follow-up,yielding an overall incidence rate of 9.43%(95%CI=7.895%-10.902%).According to baseline serum FGF21 level,the subjects were divided into Q1-Q4 groups,with the lowest level of FGF21 in the Q1 group,and the Q4 group had a significantly higher eGFR than the other groups(P<0.05).After a mean follow-up time of 4 years,UACR was increased by 0.87 mg/g(P<0.001)and eGFR was reduced by 4.8 mL/(min·1.73 m2)(P<0.001).After stratification by FGF21 quartiles,there were differences in the declines of eGFR across groups,with the lowest degree of reduction in the Q2 group.In the multivariate regression model,the serum level of FGF21 was significantly negatively associated with the onset of CKD.When FGF21 was analyzed as a continuous variable in the multivariate lo-gistic regression analysis,FGF21 was still significantly negatively associated with the risk of CKD,which was consistent with the re-sults of the quartile-based analysis.However,restricted cubic spline curves showed an L-shaped non-linear relationship between FGF21 level and the risk of CKD,i.e.,the incidence rate of CKD de-creased with the increase in FGF21 level,but when FGF21 level reached a certain threshold,the risk of CKD no longer changed with FGF21.The linear regression analysis showed that FGF21 was positively associated with UACR and eGFR.Conclusion:In this pro-spective cohort study,FGF21 level might be potentially associated with the future risk of CKD among adults with prediabetes,while fur-ther studies are needed to clarify related mechanisms and clinical value.

Objective To investigate the value of contrast-enhanced ultrasound(CEUS)liver imaging reporting and data system version 2017(LI-RADS v2017)in the differential diagnosis between hepatocellular carcinoma(HCC)and other hepatic malignancies(OM)less than or equal to 3 cm.Methods The clinical and imaging data of 163 liver lesions less than or equal to 3 cm in 126 patients with pathologically-confirmed liver malignancy were retrospectively analyzed.The patient underwent CEUS from Jan.2018 to Jun.2022 in our hospital,including 133 with HCC and 30 with OM.Nodules were classified based on the CEUS features according to the CEUS LI-RADS v2017.The evaluation of CEUS characteristics and CEUS LI-RADS v2017 in differential diagnosis of HCC and OM were calculated based on pathological findings.Results There were significant differences in the characteristics of arterial phase enhancement,timing of washout onset and washout degree between the HCC group and the OM group(all P＜0.001).The HCC group was mainly LR-3(20 lesions,15.04%),LR-4(25 lesions,18.80%)and LR-5(82 lesions,61.65%),and the OM group was mainly LR-M(28 lesions,93.33%).The specificity and positive predictive value of late washout for HCC were 93.33%(28/30)and 98.06%(101/103),respectively;and the sensitivity of early washout for OM was 93.33%(28/30).With LR-5 as the criterion to diagnose HCC,the sensitivity was 61.65%(82/133),the specificity was 93.33%(28/30),and the positive predictive value was 97.62%(82/84);with LR-4/5 as the criterion to diagnose HCC,the sensitivity was 80.45%(107/133),the specificity was 93.33%(28/30),and the positive predictive value was 98.17%(107/109),with the sensitivity of LR-4/5 being significantly higher than those of LR-5(P=0.001).With LR-M as the criterion to diagnose OM,the sensitivity was 93.33%(28/30)and the specificity was 95.49%(127/133).Conclusion The CEUS LI-RADS v2017 can effectively distinguish HCC from OM less than or equal to 3 cm.LR-5 has a low sensitivity for HCC,while LR-4/5 can improve the sensitivity for HCC.

Enamel demineralization, the formation of white spot lesions, is a common issue in clinical orthodontic treatment. The appearance of white spot lesions not only affects the texture and health of dental hard tissues but also impacts the health and aesthetics of teeth after orthodontic treatment. The prevention, diagnosis, and treatment of white spot lesions that occur throughout the orthodontic treatment process involve multiple dental specialties. This expert consensus will focus on providing guiding opinions on the management and prevention of white spot lesions during orthodontic treatment, advocating for proactive prevention, early detection, timely treatment, scientific follow-up, and multidisciplinary management of white spot lesions throughout the orthodontic process, thereby maintaining the dental health of patients during orthodontic treatment.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Background: Intraoperative hypercapnia reduces the time to emergence from volatile anesthetics, but few clinical studies have explored the effect of hypercapnia on the emergence time from intravenous (IV) anesthesia. We investigated the effect of inducing mild hypercapnia during the recovery period on the emergence time after total IV anesthesia (TIVA). Methods: Adult patients undergoing transurethral lithotripsy under TIVA were randomly allocated to normocapnia group (end-tidal carbon dioxide [ETCO2] 35–40 mmHg) or mild hypercapnia group (ETCO2 50-55 mmHg) during the recovery period. The primary outcome was the extubation time. The spontaneous breathing-onset time, voluntary eye-opening time, and hemodynamic data were collected. Changes in the cerebral blood flow velocity in the middle cerebral artery were assessed using transcranial Doppler ultrasound. Results: In total, 164 patients completed the study. The extubation time was significantly shorter in the mild hypercapnia (13.9 ± 5.9 min, P = 0.024) than in the normocapnia group (16.3 ± 7.6 min). A similar reduction was observed in spontaneous breathing-onset time (P = 0.021) and voluntary eye-opening time (P = 0.008). Multiple linear regression analysis revealed that the adjusted ETCO2 level was a negative predictor of extubation time. Middle cerebral artery blood flow velocity was significantly increased after ETCO2 adjustment for mild hypercapnia, which rapidly returned to baseline, without any adverse reactions, within 20 min after extubation. Conclusions Mild hypercapnia during the recovery period significantly reduces the extubation time after TIVA. Increased ETCO2 levels can potentially enhance rapid recovery from IV anesthesia.
