Objective To explore the potential categories and influencing factors of dietary behavioral adherence trajectories in young and middle-aged patients with type 2 diabetes mellitus.Methods A convenience sampling method was used to investigate 277 young and middle-aged patients with type 2 diabetes mellitus admitted to the Department of Endocrinology of a tertiary A hospital in Huai'an City,China,from September 2022 to March 2023.The baseline data were collected using a general information questionnaire,the Dietary Behavioral Compliance Scale for Patients with Type 2 Diabetes Mellitus,the Diabetes Self-Efficacy Scale,the Diabetes Knowledge Text,the Health Beliefs Questionnaire,and the Family APGAR Index Questionnaire.The baseline information was collected on the patients'behavioral adherence trajectories a day prior to hospital discharge(T0),a week post-discharge(T1),a month post-discharge(T2),and 3 months post-discharge(T3)to assess the level of patients'dietary behavioral adherence,using latent variable growth mixed models to identify trajectory categories,and univariate and multivariate logistic regression to analyze the influences on dietary adherence trajectories.Results A total of 3 trajectories of dietary behavior adherence in young and middle-aged patients with type 2 diabetes mellitus were identified,namely,low adherence-fluctuating group(49.8%),high adherence-slowly regressing group(31.4%),and medium adherence-continuously rising group(18.8%),and the results showed that age,literacy level,self-efficacy,health beliefs,and family caring were the factors influencing potential categories of dietary behavioral adherence for young and middle-aged patients with type 2 diabetes mellitus.Conclusion There is heterogeneity in the adherence trajectories of young and middle-aged patients with type 2 diabetes mellitus,and healthcare professionals can develop targeted interventions according to the influencing factors of the trajectory categories in order to improve their adherence.

Objective To analyze the safety and efficacy of neuroendoscopic minimally invasive surgery and traditional extraventricular drainage in the treatment of severe hypertensive intraventricular hemorrhage.Methods The clinical data of 50 cases with neuroendoscopic ventricular hematoma evacuation(endoscopy group)and 44 cases with traditional ventricles external puncture drainage(drainage group)from July 2020 to July 2023 were retrospectively analyzed,and the hematoma clearance rates,classification of activities of daily living(ADL)scale,incidence of hydrocephalus,secondary bleeding,intracranial infection,and pulmonary infection were observed between the two groups of patients.Results After surgery,the proportion of patients with hematoma clearance rate>60％and ADL grades Ⅰ,Ⅱ,and Ⅲ in the endoscopy group were significantly higher than those in the drainage group[the proportion of patients with hematoma clearance rate>60％:88.0％(44/50)vs.47.7％(21/44),χ2=17.794,P<0.001;the proportion of individuals with ADL grades Ⅰ,Ⅱ,and Ⅲ:94.0％(47/50)vs.77.3％(33/44),respectively,χ2=5.459,P=0.019],the incidence of complications in endoscopy group was significantly lower in the drainage group[8.0％(4/50)vs.34.1％(15/44),χ2=9.879,P=0.002].Conclusion Compared with traditional ventricular puncture drainage surgery,neuroendoscopic minimally invasive surgery for the treatment of severe hypertensive intracerebral hemorrhage with ventricular casting can achieve better treatment outcomes,a higher hematoma clearance rate,and fewer postoperative complications.

Objective: To explore the effect of different miniscrew placement heights on the distribution of biological forces produced by clear aligner combined with intramaxillary traction for mandibular molar distalization, to identify the miniscrew location that is conducive to the protection of lower anterior tooth anchorage and to provide a reference that can be used when designing clinical treatments. Methods: Mimics, GeomagicStudio 2017, SolidWorks 2016, and Ansys workbench were used to establish finite element analysis models and perform mechanical analysis under the following six working conditions: working condition 1 was the control group without miniscrews; working conditions 2 to 5 had miniscrew in the buccal bone cortex between the first and second molars of the lower jaw 10 mm, 7 mm, 4 mm, and 1 mm from the top of the alveolar crest, respectively; working condition 6 had the miniscrew in the center of the buccal tongue at the anterior edge of the ascending branch of the lower jaw 5 mm above the occlusal plane. Results: On the sagittal axis, miniscrew anchorage caused distal displacement of all teeth. Compared to the control group, in the miniscrew group, the displacement of the anterior molars exceeded that of the second molars. On the vertical axis, the result in the control group was similar to backward bending; the results in the miniscrew groups resembled the effect of a lever, lowering the lateral incisors and canines and raising the central incisors and first premolars. On the coronal axis, the second premolars and the first molars showed lingual displacement in the control group, and only the premolars and first molars showed lingual displacementin the miniscrew groups. The canines were the teeth that were most strongly affected by the change in miniscrew placement height. Conclusion The higher the miniscrew position is, the stronger the protective effect on the anterior anchorage. According to the miniscrew placement height, the mandibular arch should be properly narrowed, the central incisors and first premolars should be lowered, and the lateral incisors and canines should be raised when designing clinical treatments.
