Objective To evaluate the impact of bonded provisional restorations after bone augmentation for single-tooth implantation in the aesthetic zone on the surrounding soft tissues and patient satisfaction,and to explore its clinical restoration effect.Methods Thirty patients who underwent single-tooth implantation in the aesthetic zone of the maxillary anterior teeth and simultaneous horizontal bone augmentation in the Department of Stomatology,the First Affiliated Hospital of Wenzhou Medical University from March 2022 to March 2024 were selected,patients were randomly divided into study group and control group,with 15 cases in each group,The study group used digital intraoral scanning technology and computer-aided design/computer-aided manufacturing technology to fabricate personalized milled resin teeth,control group used traditional metal winged provisional bridges.After permanent restoration,the soft tissues were evaluated aesthetically,and the implant survival rate and the provisional restoration dropout rate,pink esthetic score(PES)were statistically analyzed.Patients were also asked to evaluate their satisfaction with the clinical effect of the provisional restoration.Results At the end of the observation period,93.33％(28/30)of the provisional restorations remained.All 30 implant restorations in the aesthetic zone were successfully restored,with no early implant failure or bone augmentation failure requiring reoperation.The average total score of PES in study group was(10.00±1.55)points,while in control group was(9.13±1.81)points.The distribution of PES segments in both groups were mainly in the middle segment.The satisfaction evaluation scores of both groups of patients were relatively high,but the mean score of study group was higher,and the difference was statistically significant(P＜0.05);The pronunciation,foreign body sensation,and color scores of patients in study group were higher than those in control group,and the difference was statistically significant(P＜0.05).Conclusion The clinical restoration effect of using adhesive temporary restorations after incremental single tooth bone implantation in the aesthetic area is good,with high patient's satisfaction,and personalized cutting resin temporary restorations are relatively better.

Objective:To investigate brain damage and treatment efficacy in patients with first-episode schizophrenia with comorbid auditory and visual hallucinations and cognitive decline based on brain magnetic resonance imaging (MRI).Methods:This study adopted a retrospective cohort design. Eighty patients with first-episode schizophrenia who received treatment at Wenzhou Seventh People's Hospital from January to June 2024 were included in this study. The patients were divided into an observation group (40 cases of first-episode schizophrenia with comorbid auditory and visual hallucinations) and a control group (40 cases of first-episode schizophrenia without comorbid auditory and visual hallucinations) based on whether they had symptoms of comorbid auditory and visual hallucinations. Forty healthy individuals who concurrently underwent physical examinations were included in the normal group. All patients received standardized treatment. Cranial MRI data were collected from all subjects. Cranial MRI data, Positive and Negative Syndrome Scale (PANSS) score, Global Assessment of Functioning (GAF) score, and changes in cognitive function were compared among the three groups. Additionally, the changes in cranial MRI data, PANSS score, GAF score, and the score of MATRICS Consensus Cognitive Battery (MCCB) in the observation group were compared between before and after treatment.Results:The horizontal distance between the corpus callosum and the underside of the cingulate gyrus, the vertical distance between the corpus callosum and the underside of the cingulate gyrus, and PANSS and GAF scores in the observation group were all significantly higher than those in the normal and control groups (all P < 0.05). The scores on all MCCB scales in the observation group were significantly lower than those in the normal and control groups (all P < 0.05). After treatment, the left horizontal distance between the corpus callosum and the underside of the cingulate gyrus [(5.72 ± 0.71) mm] and the right horizontal distance [(5.13 ± 0.55) mm], as well as the left vertical distance [(6.37 ± 0.69) mm] and the right vertical distance [(5.61 ± 0.67) mm], were all significantly lower than the pre-treatment values [(6.98 ± 0.83) mm, (6.07 ± 0.49) mm, (7.54 ± 0.58) mm, and (6.52 ± 0.51) mm, t = 7.30, 8.07, 8.21, 6.84, all P < 0.05]. Post-treatment PANSS scores [(39.95 ± 6.65)] were significantly lower than pre-treatment scores [(97.47 ± 18.47)], while post-treatment GAF scores [(71.26 ± 8.87)] were significantly higher than pre-treatment scores [(34.68 ± 7.71), t = 18.53, 19.69, both P < 0.05]. Post-treatment scores for the MCCB [(8.57 ± 2.45), (2.25 ± 0.47), (25.16 ± 2.43), (24.10 ± 2.64), (17.08 ± 2.25), (20.43 ± 3.76), (2.07 ± 0.36), (22.16 ± 3.24), (57.81 ± 7.69), (0.28 ± 0.05)] were significantly higher than pre-treatment scores [(5.65 ± 1.37), (1.62 ± 0.34), (21.21 ± 2.27), (20.27 ± 1.78), (12.16 ± 2.08), (14.56 ± 2.34), (1.71 ± 0.25), (17.92 ± 1.64), (40.29 ± 6.56), (0.21 ± 0.03), t = 6.58, 6.87, 7.51, 7.61, 10.15, 8.38, 5.19, 7.38, 10.96, 7.59, all P < 0.05]. Conclusions:The comorbid auditory and visual hallucinations in patients with first-episode schizophrenia, based on brain MRI findings, are closely related to cognitive decline and brain damage. After treatment, both cognitive function and cranial damage in these patients have considerably improved, which is worthy of clinical consideration.

Purpose: Drug resistance is one of the main causes of chemotherapy failure in patients with small cell lung cancer (SCLC), and extensive biological studies into chemotherapy drug resistance are required. Materials and Methods: In this study, we performed lncRNA microarray, in vitro functional assays, in vivo models and cDNA microarray to evaluate the impact of lncRNA in SCLC chemoresistance. Results: The results showed that KCNQ1OT1 expression was upregulated in SCLC tissues and was a poor prognostic factor for patients with SCLC. Knockdown of KCNQ1OT1 inhibited cell proliferation, migration, chemoresistance and promoted apoptosis of SCLC cells. Mechanistic investigation showed that KCNQ1OT1 can activate transforming growth factor-β1 mediated epithelial-to-mesenchymal transition in SCLC cells. Conclusion Taken together, our study revealed the role of KCNQ1OT1 in the progression and chemoresistance of SCLC, and suggested KCNQ1OT1 as a potential diagnostic and prognostic biomarker in SCLC clinical management.

Objective To investigate the effects of 17-methoxyl-7-hydroxy-benzene-furabcgakcone( MHBFC ) on isoproterenol-induced ventricular remodeling in mice. Methods Isoproterenol(ISO)was given subcutaneously(1 mg·kg-1, twice per day for 7 d)to induce ventricular remodeling in mice. Mice were divided into normal control group,model group, captopril group,MHBFC low and high-dose groups. 65 mg·kg-1 captopril was given by intragastric administration in captopril group,2. 5,5. 0 mg·kg-1 MHBFC were given by intravenous injection in MHBFC low and high-dose groups. At the end of the 7th day,the hearts of the mice were weighted,and myocardial hypertrophy index was expressed as heart weight/body weight, double kidneys weight/body weight and lung weight/body weight( HW/BW,KW/BW and LW/BW). Colorimetric method was used to determine the content of hydroxyproline( Hyp)in heart,the activity of superoxide dismutase( SOD)and the content of malondialdehyde( MDA)in serum. The histological changes were observed by HE and Masson’s staining,the changes of cross section area( CSA),collagen volume fraction,( CVF)and perivascular circumferential collagen area( PVCA)were determined. Results Compared with the model group,MHBFC potently inhibited cardiomyocyte hypertrophy,decreased the HW/BW, KW/BW and LW/BW,improved cardiac pathology changed,increased the of activity SOD,decreased the content of MDA in serum and the content of Hyp in heart tissue(P﹤0. 01 or P﹤0. 05),decreased the CVF and PVCA(P﹤0. 01). Conclusion MHBFC possesses protective effects against ISO-induced ventricular remodeling in mice,which may be related to its actions in reducing the oxidative stress and improving the antioxidant activity of the body.

Objective: Lung metastases are common in patients with differentiated thyroid carcinoma (DTC). Post-therapeutic 131I-whole-body scan (WBS) was conventionally administered after the radioactive iodine treatment (RAI) of DTC lung metastases. This study aimed to investigate the influencing factors of WBS imaging on the RAI of DTC lung metastases. Methods:DTC patients (n=60) with lung metastases treated with 131I were retrospectively included. Before treatment, the thyroid function was assessed. Neck and chest computed tomography (CT) was performed, and WBS was inspected. Patients with lung metastases were classified into negative and positive subgroups according to the imaging of 131I WBS, and the relative influencing factors were analyzed. Results:Univariate analy-sis showed that age and chest CT imaging, which revealed pulmonary fibrosis, calcification, and patchy shadows, were related to WBS imaging. Binary variable logistic regression analysis revealed that pulmonary fibrosis (OR=0.175, P<0.001) and calcification (OR=0.088, P<0.05) went against the development of WBS. Conclusion:WBS imaging on RAI of lung metastases was not obvious in the el-derly. The fibrosis, calcification, and patchy shadows of the lung were not conducive for WBS imaging. The fibrosis and calcification of the lung were the main factors that affect WBS imaging.
