During orthodontic treatment, clinical monitoring of patients is a crucial factor in determining treatment success. It aids in timely problem detection and resolution, ensuring adherence to the intended treatment plan. In recent years, digital technology has increasingly permeated orthodontic clinical diagnosis and treatment, facilitating clinical decision-making, treatment planning, and follow-up monitoring. This review summarizes recent advancements in digital technology for monitoring orthodontic tooth movement, related complications, and appliance-wearing compliance. It aims to provide insights for researchers and clinicians to enhance the application of digital technology in orthodontics, improve treatment outcomes, and optimize patient experience. The digitization of diagnostic data and the visualization of dental models make chair-side follow-up monitoring more convenient, accurate, and efficient. At the same time, the emergence of remote monitoring technology allows orthodontists to promptly identify oral health issues in patients and take corresponding measures. Furthermore, the multimodal data fusion method offers valuable insights into the monitoring of the root-alveolar relationship. Artificial intelligence technology has made initial strides in automating the identification of orthodontic tooth movement, associated complications, and patient compliance evaluation. Sensors are effective tools for monitoring patient adherence and providing data-driven support for clinical decision-making. The application of digital technology in orthodontic monitoring holds great promise. However, challenges like technical bottlenecks, ethical considerations, and patient acceptance remain.

OBJECTIVE To explore the potential mechanism of ketamine-induced cognitive impairment in mice based on metabolomics. METHODS Male C57BL/6 mice were randomly divided into control group and ketamine group （25 mg/kg）， with 12 mice in each group. Each group of mice was intraperitoneally injected with normal saline or corresponding drugs， 4 times a day， for 10 consecutive days. On the last 2 days of drug administration， the cognitive behavior was evaluated by Y maze and novel object recognition test， and the histopathological changes in the prefrontal cortex （PFC） were observed. Ultra-high performance liquid chromatography-tandem mass spectrometry technology was used to analyze the changes of metabolites in PFC， screen for differential metabolites， and perform pathway enrichment analysis. RESULTS Compared with the control group， the morphology of PFC neurons in the ketamine group of mice was inconsistent. There were cavities around the nucleus， and the number of deeply stained cells increased. The mean optical density value of the Nissl staining positive area was significantly reduced， and the alternation rate and discrimination index were significantly reduced （P＜0.05 or P＜0.01）. In the PFC tissue samples of mice of the two groups， there were a total of 114 differential metabolites， including 73 up-regulated and 41 down-regulated metabolites， including glutamine， succinic acid， ketoglutarate， and choline， etc. The differential metabolites mentioned above were mainly enriched in metabolism of alanine， aspartate and glutamate， metabolism of arginine and proline， γ aminobutyric acid synapses， pyrimidine metabolism， cholinergic synapses pathways， etc. CONCLUSIONS Ketamine can induce cognitive impairment in mice. Its neurotoxicity is related to abnormal synaptic transmission and energy metabolism， and neuroimmune regulation disorders.

⁶⁰Co-γ ray irradiation has the unique advantages of high efficiency， strong penetration， operation at room temperature and no residue， which has been widely used in the sterilization of Chinese medicinal materials， decoction pieces， Chinese patent medicine. However， the irradiation effect may cause changes in the content of chemical components in Chinese materia medica or the emergence of new radiolysis products， leading to reduced efficacy and uncontrollable safety risks. This paper reviewed the relevant literature at home and abroad， summarized the effect of irradiation sterilization on various types of chemical compositions of Chinese medicinal materials and their preparations， and analyzed and explored the rule of change. The results showed that the content changes of various chemical components in Chinese materia medica after ⁶⁰Co-γ ray irradiation sterilization varied. The contents of most flavonoids， terpenoids， phenylpropanoids and quinones decreased after irradiation， and the degree of decrease increased with the elevated irradiation dose. The contents of lignans， alkaloids， isoflavones and some terpenoids did not change significantly before and after irradiation， while the content changes of triterpenoid saponins， dihydroflavonols， chalcones， sugars and glycosides after irradiation were not yet uniform. Therefore， it is recommended to pay attention to the compositional changes of irradiated Chinese medicines， strengthen the research on the standards of irradiated Chinese medicines， and standardize the irradiation and sterilization of Chinese medicines in order to promote the healthy and rational application of irradiated Chinese medicines.

ObjectiveTo investigate the effects of Xinfeng capsules combined with chronic disease management of traditional Chinese medicine （TCM） on rapid disease control and short-term prognosis of patients with rheumatoid arthritis （RA）. MethodsA total of 80 RA patients hospitalized in the Department of Rheumatology of The First Affiliated Hospital of Anhui University of Chinese Medicine from January 2022 to March 2024 were enrolled and randomly divided into an observation group （40 cases） and a control group （40 cases）. The control group was treated with conventional methotrexate combined with standard chronic disease management， while the observation group was additionally treated with Xinfeng Capsules combined with TCM chronic disease management. The treatment course lasted 24 weeks. The outcomes were compared between two groups， including disease activity ［28-joint disease activity score （DAS28）， clinical disease activity index （CDAI）， simplified disease activity index （SDAI）］， visual analogue scale （VAS） for pain， TCM syndrome score， tender joint count （TJC）， swollen joint count （SJC）， morning stiffness duration， Health Assessment Questionnaire （HAQ）， Self-Rating Anxiety Scale （SAS）， Self-Rating Depression Scale （SDS）， American College of Rheumatology （ACR） 20%， 50% and 70% response rates （ACR20/50/70）， erythrocyte sedimentation rate （ESR）， high-sensitivity C-reactive protein （hs-CRP）， rheumatoid factor （RF）， anti-cyclic citrullinated peptide antibody （CCP-Ab）， interleukin （IL）-6， IL-1β， tumor necrosis factor-α （TNF-α）， and serum immunoglobulin G （IgG）. The Chronic Disease Self-Management Scale （CDSMS） was used to evaluate patients’ self-management ability， self-care ability， and nursing satisfaction. Patients were followed up for 12 weeks to assess prognosis， and COX regression analysis was performed to determine the impact on short-term prognosis. ResultsAfter treatment， TJC， SJC， morning stiffness duration， DAS28， CDAI， SDAI， VAS， TCM syndrome score， ESR， hs-CRP， RF， CCP-Ab， IL-6， IL-1β， TNF-α， IgG， HAQ， SAS， SDS， chronic disease self-management behavior， self-efficacy， and self-care ability all improved significantly in both groups compared with baseline （P<0.05，P<0.01）. Compared with the control group， the observation group showed more significant improvements in TJC， SJC， morning stiffness duration， DAS28， CDAI， SDAI， VAS， TCM syndrome score， ESR， IL-1β， IgG， HAQ， SAS， SDS， self-care ability， chronic disease self-management behavior， and self-efficacy （P<0.05 or P<0.01）. The ACR70 response rate and nursing satisfaction were significantly higher in the observation group than in the control group （P<0.01）. COX regression analysis showed that Xinfeng capsules combined with TCM chronic disease management reduced the risk of poor short-term prognosis in RA patients. ConclusionXinfeng capsules combined with TCM chronic disease management facilitates rapid disease control in RA patients， effectively improves short-term prognosis， and plays an important role in the treatment of the disease.

Objective:To describe and analyze suicide risk of patients with schizophrenia,major depressive disorder,and bipolar disorder.Methods:A total of 2 016 patients with schizophrenia,903 patients with major de-pressive disorder,and 381 patients with bipolar disorder from inpatients,clinics,or communities who met the diag-nostic criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition were recruited.All patients were interviewed by psychiatrists using the Mini International Neuropsychiatric Interview to diagnose mental disor-ders and assess suicide risk,as well as Clinical-Rated Dimensions of Psychosis Symptom Severity(CRDPSS)to as-sess symptoms.Differences and risk factors of suicide risk among three types of mental disorders were explored u-sing multivariate logistic regression analysis.Results:In the past one month,37 patients with schizophrenia(1.8％),516 patients with major depressive disorder(57.1％),and 102 patients with bipolar disorder(26.8％)had suicide risk.Compared with patients with schizophrenia,suicide risk in patients with major depressive disorder(OR=36.50)and bipolar disorder(OR=20.10)increased.Female(OR=1.87),smoking(OR=1.76),family history of suicide(OR=5.09),higher score of CRDPSS hallucination(OR=1.80),and higher score of CRDPSS depression(OR=1.54)were risk factors of suicide risk of patients.Conclusions:Suicide risk of patients with ma-jor depressive disorder and bipolar disorder is higher than that of patients with schizophrenia.In clinical practice,it is important to regularly assess suicide risk of patients.Patients who experience symptoms of hallucination and de-pression should be paid more attention to.

Objective: To explore the association of the interaction between vitamin D deficiency and dyslipidemia with the comorbidity risk of overweight and obesity in children and adolescents, so as to provide the theoretical basis for prevention and control of overweight and obesity in children and adolescents. Methods: The data for the study was obtained from the population aged 6-17 in Hebei Province during the 2022-2023 monitoring of nutrition and health status of Chinese residents. A stratified cluster random sampling method was used to conduct questionnaire surveys, physical measurements, and laboratory tests on 2 118 children and adolescents. Logistic regression was used to analyze the association of vitamin D deficiency and dyslipidemia with overweight and obesity, and multiplication and addition models were used to analyze the interaction of vitamin D deficiency and dyslipidemia with overweight and obesit. Results: The prevalence of vitamin D deficiency in the surveyed children and adolescents was 67.80%, the incidence of dyslipidemia was 24.46%, and the prevalence of overweight and obesity was 41.97%. After adjusting for confounding factors, the results of multivariate Logistic regression analysis showed that there was no multiplicative interaction of vitamin D deficiency and dyslipidemia with overweight and obesit ( OR=0.90, 95%CI=0.57-1.43, P >0.05). However, the risk of overweight and obesity among children and adolescents with vitamin D deficiency and dyslipidemia was 3.99 times higher than that of those with sufficient vitamin D and normal blood lipids ( OR=3.99, 95%CI=2.93-5.45, P <0.01). There was a positive additive interaction between vitamin D deficiency and dyslipidemia, with relative excess risk of interaction, attributable proportion of interaction and synergy index of 14.40, 81.50% and 7.35, respectively. Conclusions For children and adolescents, there is a synergistic effect between vitamin D deficiency and dyslipidemia, and the coexistence of both increases the risk of overweight and obesity. Comprehensive prevention and control measures should be taken to timely supplement vitamin D and maintain normal blood lipid levels, to reduce the occurrence of overweight and obesity in children and adolescents.

ObjectiveTo investigate the mechanism of acupuncture in the treatment of chemotherapy-related cognitive impairment （CRCI） of breast cancer based on resting-state functional magnetic resonance imaging （rs-fMRI）. MethodTwenty-five patients with CRCI of breast cancer were included and treated with the acupuncture based on the method of regulating qi and blood， nourishing mind and benefiting intelligence； the selected acupoints included Zusanli （ST 36， bilateral）， Xuehai （SP 10， bilateral）， Tanzhong （CV 17）， Zhongwan （CV 12）， Qihai （CV 6）， Baihui （GV 20）， Fengfu （GV 16， bilateral）， Xinshu （BL 15， bilateral）， Tongli （HT 5， bilateral）， Zhaohai （KI 6， bilateral）， Yixi （BL 45， bilateral） twice a week， each time interval of 2-3 days， for 8 weeks. The scores of Montreal Cognitive Assessment （MoCA）， Mini-mental State Examination （MMSE）， European Cancer Research and Treatment Organization Quality of Life Questionnaire （EORTC QLQ-C30） were compared before and after acupuncture， and the effectiveness were evaluated by MoCA scale. The patients received rs-fMRI before and after treatment， and used low-frequency oscillation amplitude and functional connectivity （FC） analysis to extract the mean zALFF values of regions of interest such as bilateral anterior cingulate gyrus， bilateral hippocampus， bilateral amygdala， bilateral temporal pole middle temporal gyrus， and bilateral temporal pole supramarginal gyrus for comparison， and used the brain regions with statistically significant differences in the pre- and post-treatment zALFF values as the seed points for the seed-point-based FC Analysis. Correlation analyses were performed between the imaging metrics and the clinical scales. ResultsTwenty-four patients with CRCI of breast cancer completed treatment and follow-up. The zALFF values of the left hippocampus， left amygdala， and left temporal pole temporal gyrus in patients' rs-fMRI decreased after treatment （P＜0.05 or P＜0.01）， and left temporal pole temporal gyrus and right posterior cerebellar lobe FC were elevated （t = -5.169）， and MoCA scale total scores and visuospatial and executive， naming， and delayed recall cognitive scores， MMSE scale total scores， and EORTC QLQ-C30 scale mood scores were significantly higher （P＜0.05 or P＜0.01）. The total effective rate of MoCA was 58.33%. The difference in zALFF values of the left temporal pole middle temporal gyrus before and after treatment was negatively correlated with the MoCA total score （r= -0.499， P = 0.015）， as well as the difference in abstract function （r = -0.498， P = 0.016）. ConclusionThe acupuncture method of regulating qi and blood， nourishing mind and benefiting intelligence can improve the cognitive function of breast cancer patients with CRCI， and its mechanism may be related to improving the functional activities of hippocampus， amygdala and temporal lobe， as well as the functional connections of left temporal pole-temporal middle gyrus and right posterior cerebellar lobe.
