Objective To evaluate the efficacy of elastic appliances in the early correction of Class Ⅱmalocclusions in the replacement dentition.Methods A total of 15 children aged 7-9 years who were admit-ted to the Affiliated Stomatology Hospital of Southwest Medical University from June 2018 to August 2023 were selected as the observation group,and 15 children who were consulted but not treated in the hospital dur-ing the same period were selected as the control group.The changes of bone tissue,dental and alveolar tissue,soft tissue and occlusal relationship before and after treatment were evaluated in the two groups.In addition,X-ray images of the observation group were collected every 8 to 10 months for the whole process dynamic mo-nitoring.Results Before treatment,there was no significant difference in all indexes between the two groups(P＞0.05).After treatment,there were statistical significances in the upper and lower alveolar base Angle(ANB),mandibular branch length(GO-CO),mandibular height(ANS-Me),mandibular position(S-GO),up-per central incisor inclination(U1-NA Angle),upper central incisor inclination convexity(U1-NA),lower central incisor process distance(L1-APo),the Z Angle and FH-N'Pg'Angle of soft tissue between the two groups(P＜0.05).After treatment,the covering OB and covering OJ in the observation group were lower than those in the control group,and the proportion of ClassⅠ patients in molar relationship was higher than that in the control group,with statistical significance(P＜0.05).After 3-4 years of treatment,ANB gradual-ly decreased,and the anterior-basilar plane-mandibular plane Angle(SN-MP)remained basically stable,and had a slight decreasing trend in the later period.The U1-NA Angle and the lower central incisor inclination(L1-NB Angle)were close to the normal mean during the whole treatment.Conclusion Using elastic appli-ances to treat patients with early replacement Class Ⅱ malocclusion,after 3-4 years monitoring and guid-ance,it can effectively improve the molar relationship,promote forward jaw growth,and create a harmonious and aesthetically pleasing facial soft tissue.

ObjectiveTo explore the dose-effect relationship and safety of high， medium， and low doses of raw Astragali Radix in the modified Huangqi Chifengtang （MHCD） for treating proteinuria in immunoglobulin A （IgA） nephropathy， and to provide scientific evidence for the clinical use of high-dose Astragali Radix in the treatment of proteinuria in IgA nephropathy. MethodsA total of 120 patients with IgA nephropathy， diagnosed with Qi deficiency and blood stasis combined with wind pathogen and heat toxicity， were randomly divided into a control group and three treatment groups. The control group received telmisartan combined with a Chinese medicine placebo， while the treatment groups were given telmisartan combined with MHCD containing different doses of raw Astragali Radix （60， 30， 15 g）. Each group contained 30 patients， and the treatment period was 12 weeks. Changes in 24-hour urinary protein （24 hUTP）， traditional Chinese medicine （TCM） syndrome scores， effective rate， and renal function were observed before and after treatment. Safety was assessed by monitoring liver function and blood routine. ResultsAfter 12 weeks of treatment， 24 hUTP significantly decreased in the high， medium， and low-dose groups， as well as the control group （P<0.05， P<0.01）. The TCM syndrome scores in the high， medium， and low-dose groups also significantly decreased （P<0.01）. Comparisons between groups showed that the 24 hUTP in the high-dose group was significantly lower than in the medium， low-dose， and control groups （P<0.05， P<0.01）， and the 24 hUTP in the medium-dose group was significantly lower than in the control group （P<0.05）. The TCM syndrome scores in the high and medium-dose groups were significantly lower than in the low-dose and control groups （P<0.05， P<0.01）. The total effective rates for proteinuria in the high， medium， low-dose， and control groups were 92.59% （25/27）， 85.19% （23/27）， 60.71% （17/28）， and 57.14% （16/28）， respectively. The effective rates in the high and medium-dose groups were significantly higher than in the low-dose and control groups （χ²=13.185， P<0.05， P<0.01）. The effective rates for TCM syndrome scores in the high， medium， low-dose， and control groups were 88.89% （24/27）， 81.48% （22/27）， 71.43% （20/28）， and 46.43% （13/28）， respectively. The efficacy of TCM syndrome scores in the high and medium-dose groups was significantly higher than in the control group （χ²=14.053， P<0.01）. Compared with pre-treatment values， there was no statistically significant difference in eGFR and serum creatinine in the high and medium-dose groups. However， eGFR significantly decreased in the low-dose and control groups after treatment （P<0.05）， and serum creatinine levels increased significantly in the control group （P<0.05）. No statistically significant differences were observed in urea nitrogen， uric acid， albumin， total cholesterol， triglycerides， liver function， and blood routine before and after treatment in any group. ConclusionThere is a dose-effect relationship in the treatment of IgA nephropathy with high， medium， and low doses of raw Astragali Radix in MHCD. The high-dose group exhibited the best therapeutic effect and good safety profile.

Objective To translate the Context Assessment for Community Health(COACH)scale into Chinese,thereby providing a standardized measurement tool for context assessment in clinical evidence-based practice.Methods The scale was translated following the Brislin translation model,ultimately forming the Chinese version of the COACH scale.Using convenience sampling,584 healthcare professionals were recruited from 3 tertiary hospitals in Jiangxi,Henan,and Liaoning provinces and 2 community hospitals in Liaoning province from May to September 2024 to evaluate the reliability and validity of the scale.In October 2024,the Chinese version of COACH was applied to 44 healthcare professionals in a hypertension specialist ward of a provincial tertiary hospital.Results Of the 584 distributed questionnaires,519 valid questionnaires were collected(the effective response rate of 88.87％).The Chinese version consists of 7 dimensions with 42 items.The overall Cronbach's α coefficient was 0.975;the McDonald's omega coefficient was 0.979;split-half reliability was 0.808,and the test-retest reliability was 0.917.The scale-content validity index/average was 0.950,and the scale-content validity index/universal agreement was 0.980,with item-content validity index ranging from 0.775 to 1.000.Exploratory factor analysis extracted 7 factors,accounting for 79.260％of the cumulative variance,with factor loadings ranging from 0.569 to 0.954.Confirmatory factor analysis showed good model fit.The preliminary application results showed that the total score of the scale was 185.18±17.82.The correlation coefficients between dimensions and total score ranged from 0.116 to 0.905.Conclusion The Chinese version of the COACH scale demonstrates good reliability and validity,making it suitable as a context measurement tool for implementation research at different stages in clinical and public health settings.

Objective:To carry out a scoping review on eHealth literacy in patients with cardiovascular disease to sort out eHealth literacy from four aspects of concepts, assessment tools, influencing factors and interventions, with a view to informing future research and practice.Methods:Based on Arksey and O'Malley's framework for reporting scoping reviews, the literature on eHealth literacy in patients with cardiovascular disease was systematically searched in PubMed, Web of Science, Embase, Cochrane Library, CINAHL, China National Knowledge Infrastructure, VIP, Wanfang Data, and China Biomedical Database. The search period was from database establishment to May 3, 2024. Literature was screened, summarized and analyzed.Results:A total of 23 papers were included. The concepts and theoretical frameworks on eHealth literacy had their own focus, but no consensus was reached. The most commonly used tool to assess eHealth literacy in patients with cardiovascular disease was the eHealth Literacy Scale. The influencing factors included four aspects of demographic sociological and disease-related factors, psycho-cognitive factors, eHealth literacy knowledge and skills, and other factors. Interventions to improve eHealth literacy among patients with cardiovascular disease primarily included eHealth literacy training and use of portal-related digital toolkit.Conclusions:Currently there is no specific assessment tool for eHealth literacy for cardiovascular disease patients. In the future, eHealth literacy assessment tools need to be revised and improved according to the population characteristics and cultural background of cardiovascular disease patients. E-health literacy among patients with cardiovascular disease is at a moderately low level and is influenced by multiple factors. The influencing factors can be analyzed in depth through large-sample cross-sectional studies or longitudinal studies, and then a variety of intervention programs can be constructed at home or in the community with the help of multimedia and apps, with a view to improving the e-health literacy of patients with cardiovascular diseases.

Objective:To construct bacterial cytoplasmic membrane nanovesicles(BMV)with overexpressing programmed death 1(PD-1),denoted as BMV-PD-1 and evaluate the targeting efficacy of BMV-PD-1 towards transplanted lung tumor tissues in mice.Methods:The fusion plasmid ClyA-PD-1-EGFP fused by PD-1 and Cytolysin A(ClyA)was transferred into Escherichia coli BL21-Codonplus through plasmid transformation.Laser confocal microscopy,SDS-PAGE,and WB were used to detect the expression of the fusion protein ClyA-PD-1-EGFP.Bacterial membranes were extracted and processed with an extruder to generate BMV-PD-1.TEM and NTA were utilized to assess the morphology,size distribution,and zeta potential of BMV-PD-1,while WB was used to verify the presence of PD-1 protein.Laser confocal imaging was conducted to monitor the uptake of BMV-PD-1 by Lewis lung cancer cells.A C57BL/6J mouse subcutaneous transplant tumor model of LLC lung cancer cells was constructed,and the tumor targeting of BMV-PD-1 was evaluated by small animal imaging system.Results:Laser confocal microscopy images demonstrated that the plasmid ClyA-PD-1-EGFP was transferred into BL21-Codonplus and successfully expressed into protein.SDS-PAGE results suggested that ClyA-PD-1-EGFP was overexpressed in BL21-Codonplus.WB analysis indicated that PD-1 was expressed in bacteria and highly expressed in BMV-PD-1(P<0.001).NTA and TEM analyses revealed that BMV-PD-1 were spherical vesicles with a diameter of(145±14)nm and a negative surface charge.Laser confocal imaging showed that the high expression of PD-1 significantly increased the uptake of BMV-PD-1 by lung cancer cells(P<0.01).In vivo imaging of small animals further confirmed that the high expression of PD-1 can effectively improve cancer targeting of BMV-PD-1(P<0.01).Conclusion:In this study,bacterial plasma membrane nanovesicles BMV-PD-1 with high PD-1 expression are successfully constructed,and it is found that PD-1 overexpression markedly improve the mouse lung cancer xenograft tissue targeting specificity of BMV-PD-1,laying the groundwork for further development of BMV-PD-1 as a carrier for targeted drug delivery systems in tumors.

Background Environmental noise pollution is serious, and there are few studies on the effects of long-term noise exposure during sleep on cognitive function and possible biological clock mechanism. Objective To explore the cognitive impairment induced by noise exposure during sleep in mice and possible biological clock mechanism, and to provide a theoretical basis for the protection against noise exposure. Methods Twenty male C57BL/6J mice were randomly divided into a control group and a noise-exposed group, 10 mice in each group. The noise-exposed group was exposed to sleep-period noise using a noise generator for 12 h (08:00–20:00) per day for a total of 30 d. The calibrated noise intensity was set at 90 dB. No intervention was imposed on the control group. At the end of the noise exposure, cognitive function of mice was examined using the new object recognition experiment and the open field test, and the hippocampal tissue damage of mice were evaluated by Nissl staining, ionized calcium binding adaptor molecule 1 (Iba1) immunofluorescence staining, and real-time fluorescence quantitative PCR for inflammatory factors and biological clock genes. Oxidative stress indicators in the hippocampus of mice were also detected by assay kit. Results After noise exposure during sleep period, the results of new object recognition experiment showed that the discrimination index of mice in the noise-exposed group was 0.06±0.04, which was significantly lower than that of the control group (0.65±0.13) (P<0.05). The results of open field test showed that the central activity distance of the noise-exposed group was (242.20±176.10) mm, which was significantly lower than that of the control group, (1548.00±790.30) mm (P < 0.05), and the central activity time of the noise-exposed group was (0.87±0.64) s, which was significantly lower than that of the control group, (6.00±2.86) s (P < 0.05). The Nissl staining results showed that compared with the control group, neurons in the hippocampus of the noise-exposed mice were shrunken, deeply stained, disorganized, and loosely connected. The immunofluorescence results showed that microglia in the hippocampus of the noise-exposed mice were activated and the expression of Iba1 was significantly increased compared with those of the control group (P<0.05). The real-time PCR results of showed that the mRNA levels of the biological clock genes Clock, Per2, and Rev-erbα were significantly increased compared with those of the control group (P<0.05), and the mRNA level of Per1 was significantly decreased compared with that of the control group (P<0.05); and the mRNA levels of IL-18, IL-6, iNOS, and NLRP3 in the hippocampal tissues of mice were significantly increased compared with those of the control group (P<0.05). The results of oxidative stress evaluation showed that compared with the control group, reduced glutathione content was significantly reduced in the noise-exposed group (P<0.001). Conclusion Noise exposure during sleep period can lead to the destabilization of biological clock genes in hippocampal tissues and trigger hippocampal neuroinflammation, which can lead to the activation of microglia and cause cognitive impairment in mice.

Objective To investigate the expression of long non-coding RNA(lncRNA)small nucleolar RNA host gene(SNHG)25 and microRNA(miR)-497-5p in glioma tissues and their relationship with clinical features and prognosis.Methods A total of 157 glioma patients admitted to the hospital from January 2019 to January 2020 were selected as the glioma group,and 100 patients who underwent surgical treatment due to craniocerebral injury in the same hospital during the same period were selected as the control group.The ex-pression levels of lncRNA SNHG25 and miR-497-5p were detected in glioma tissues and normal brain tissues resected during operation.The patients were followed up for 3 years.The correlation between the expression levels of lncRNA SNHG25 and miR-497-5p was analyzed,and the relationship between the expression level of lncRNA SNHG25 and miR-497-5p and the clinical characteristics and prognosis of patients were analyzed.Re-sults Compared with the control group,the expression level of lncRNA SNHG25 in the glioma group was in-creased(P＜0.05),and the expression level of miR-497-5p was decreased(P＜0.05).Compared with the maximum diameter of tumors＜4 cm,World Health Organization(WHO)central nervous system tumor grade Ⅰ-Ⅱ,the expression level of lncRNA SNHG25 was increased and the expression level of miR-497-5p was decreased in glioma tissues with the maximum diameter of tumors ≥4 cm and WHO central nervous sys-tem tumor grade Ⅲ-Ⅳ(P＜0.05).The expression level of lncRNA SNHG25 in glioma patients was nega-tively correlated with miR-497-5p(r=-0.370,P＜0.05).The cumulative survival rate of lncRNA SNHG25 high expression group was lower than that of lncRNA SNHG25 low expression group(P＜0.05),and the cu-mulative survival rate of miR-497-5p low expression group was lower than that of miR-497-5p high expression group(P＜0.05).Grade Ⅲ-Ⅳ of WHO central nervous system tumor grade and high expression of lncRNA SNHG25 were risk factors for poor prognosis of glioma patients(P＜0.05),while high expression of miR-497-5p was a protective factor(P＜0.05).Conclusion The expression of lncRNA SNHG25 is increased and the expression of miR-497-5p is decreased in glioma tissues,which is related to the maximum diameter of tumor and high WHO central nervous system tumor grade,and can lead to poor prognosis of glioma patients.

Objective:To further improve the understanding of paroxysmal nocturnal hemoglobinuria (PNH), we retrospectively analyzed and summarized the clinical characteristics, treatment status, and survival status of patients with PNH in Zhejiang Province.Methods:This study included 289 patients with PNH who visited 20 hospitals in Zhejiang Province. Their clinical characteristics, comorbidity, laboratory test results, and medications were analyzed and summarized.Results:Among the 289 patients with PNH, 148 males and 141 females, with a median onset age of 45 (16-87) years and a peak onset age of 20-49 years (57.8% ). The median lactic dehydrogenase (LDH) level was 1 142 (604-1 925) U/L. Classified by type, 70.9% (166/234) were classical, 24.4% (57/234) were PNH/bone marrow failure (BMF), and 4.7% (11/234) were subclinical. The main clinical manifestations included fatigue or weakness (80.8%, 235/289), dizziness (73.4%, 212/289), darkened urine color (66.2%, 179/272), and jaundice (46.2%, 126/270). Common comorbidities were hemoglobinuria (58.7% ), renal dysfunction (17.6% ), and thrombosis (15.0% ). Moreover, 82.3% of the patients received glucocorticoid therapy, 70.9% required blood transfusion, 30.7% used immunosuppressive agents, 13.8% received anticoagulant therapy, and 6.3% received allogeneic hematopoietic stem cell transplantation. The 10-year overall survival (OS) rate was 84.4% (95% CI 78.0% -91.3% ) . Conclusion:Patients with PNH are more common in young and middle-aged people, with a similar incidence rate between men and women. Common clinical manifestations include fatigue, hemoglobinuria, jaundice, renal dysfunction, and recurrent thrombosis. The 10-year OS of this group is similar to reports from other centers in China.
