This study identified 8 members including NjBIN2 of the GSK3 family in Nardostachys jatamansi by bioinformatics analysis. Moreover, the phylogenetic tree revealed that the GKS3 family members of N. jatamansi had a close relationship with those of Arabidopsis. RT-qPCR results showed that NjBIN2 presented a tissue-specific expression pattern with the highest expression in roots, suggesting that NjBIN2 played a role in root growth and development. In addition, the application of epibrassinolide or the brassinosteroid(BR) synthesis inhibitor(brassinazole) altered the expression pattern of NjBIN2 and influenced the photomorphogenesis(cotyledon opening) and root development of N. jatamansi, which provided direct evidence about the functions of NjBIN2. In conclusion, this study highlights the roles of BIN2 in regulating the growth and development of N. jatamansi by analyzing the expression pattern and biological function of NjBIN2. It not only enriches the understanding about the regulatory mechanism of the growth and development of N. jatamansi but also provides a theoretical basis and potential gene targets for molecular breeding of N. jatamansi with improved quality in the future.

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.

OBJECTIVE: This study aimed to explore the interplay between the life-course body mass index (BMI) trajectories and insulin resistance (IR) on incident diabetes. METHODS: This longitudinal cohort included 2,336 participants who had BMI repeatedly measured 3-8 times between 1989 and 2009, as well as glucose and insulin measured in 2009. BMI trajectories were identified using a latent class growth mixed model. The interplay between BMI trajectories and IR on diabetes was explored using the four-way effect decomposition method. Logistic regression and mediation models were used to estimate the interaction and mediation effects, respectively. RESULTS: Three distinct BMI trajectory groups were identified: low-stable ( n = 1,625), medium-increasing ( n = 613), and high-increasing ( n = 98). Both interaction and mediation effects of BMI trajectories and IR on incident diabetes were significant ( P < 0.05). The proportion of incident diabetes was higher in the IR-obesity than in the insulin-sensitivity (IS) obesity group (18.9% vs. 5.8%, P < 0.001). After adjusting for covariates, the odds ratios (95% confidence intervals) of the IR, IS-obesity, and IR-obesity groups vs. the normal group were 3.22 (2.05, 5.16), 2.05 (1.00, 3.97), and 7.98 (5.19, 12.62), respectively. IR mediated 10.7% of the total effect of BMI trajectories on incident diabetes ( P < 0.001). CONCLUSION We found strong interactions and weak mediation effects of IR on the relationship between life-course BMI trajectories and incident diabetes. IS-obesity is associated with a lower risk of incident diabetes than IR-obesity.

Ambient air pollution is increasingly being recognized as a risk factor for heart failure; however, its effects on cardiac biomarkers remain unclear. This scoping review assessed the existing evidence on the association between air pollution and cardiac biomarkers in heart failure, described the key concepts, synthesized data, and identified research gaps. Following the PRISMA-ScR guidelines, PubMed, Embase, Web of Science, and CNKI databases were searched for studies on air pollution, heart failure, and biomarkers. A total of 765 records were screened, and 81 full texts were assessed for eligibility, resulting in 15 studies. The results showed that the exposure to particulate matter was associated with elevated N-terminal pro-B-type natriuretic peptide and troponin levels. Several studies have linked particulate matter exposure to a higher cardiovascular risk and heart failure biomarkers. Inflammatory and oxidative stress markers were consistently elevated across studies, supporting the biological relevance of these associations. However, few studies have focused specifically on populations with heart failure or clinically relevant biomarkers, and the evidence for gaseous pollutants remains inconclusive. These findings highlight the need to integrate environmental risk assessment into heart failure care and inform policy efforts to reduce the pollution-related cardiovascular burden. Further research should address these gaps through improved exposure assessments and the integration of mechanistic evidence.

Breast cancer is the most common cancer in women and one of the deadliest cancers worldwide.According to the distribution of tumor tissue,breast cancer can be divided into invasive and non-invasive forms.The cancer cells in invasive breast cancer pass through the breast and through the immune system or systemic circulation to different parts of the body,forming metastatic breast cancer.Drug resistance and distant metastasis are the main causes of death from breast cancer.Research on breast cancer has attracted extensive attention from researchers.In vitro construction of tumor models by tissue engineering methods is a common tool for studying cancer mechanisms and anticancer drug screening.The tumor microenvironment consists of cancer cells and various types of stromal cells,including fibroblasts,endothelial cells,mesenchymal cells,and immune cells embedded in the extracellular matrix.The extracellular matrix contains fibrin proteins(such as types Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅵ,and Ⅹcollagen and elastin)and glycoproteins(such as proteoglycan,laminin,and fibronectin),which are involved in cell signaling and binding of growth factors.The current traditional two-dimensional(2D)tumor models are limited by the growth environment and often cannot accurately reproduce the heterogeneity and complexity of tumor tissues in vivo.Therefore,in recent years,research on three-dimensional(3D)tumor models has gradually increased,especially 3D bioprinting models with high precision and repeatability.Compared with a 2D model,the 3D environment can better simulate the complex extracellular matrix components and structures in the tumor microenvironment.Three-dimensional models are often used as a bridge between 2D cellular level experiments and animal experiments.Acellular matrix,gelatin,sodium alginate,and other natural materials are widely used in the construction of tumor models because of their excellent biocompatibility and non-immune rejection.Here,we review various natural scaffold materials and construction methods involved in 3D tissue-engineered tumor models,as a reference for research in the field of breast cancer.

Robotic surgery is known as the"third technological revolution"in the field of surgery,and is an important milestone in the development of modern surgery.However,our country's innovative surgical robot industry is still in its early stages,and it is only being utilized in certain surgical fields.To explore the effectiveness of the application of do-mestic surgical robot in oral and maxillofacial surgery,the author successfully completed a case of benign parotid tumor resection with the assistance of a domestic autonomous robot.The operation was successful,facial nerve function was preserved,and postoperative wound healing was good.

Objective To explore the correlations between self-esteem,social support and mental health status of patients with deep bums at special sites at different stages of the disease course.Methods A total of 36 inpatients who were admitted to Department of Burn Surgery of The First Affiliated Hospital of Naval Medical University(Second Military Medical University)between Jan.2020 and Sep.2023 were enrolled.The patients were assessed with self-rating anxiety scale(SAS),self-rating depression scale(SDS),post-traumatic stress disorder(PTSD)checklist-civilian version(PCL-C),Rosenberg self-esteem scale(RSES),and perceived social support scale(PSSS)within 7 d of burns(early stage of disease),at wound closure(early rehabilitation stage),and 3 months after wound closure(late rehabilitation stage).The data were collected and invalid data were excluded for statistical analysis.Results A total of 36 patients effectively completed all the scales.There were anxiety,depression and PTSD in patients with deep bums at special sites at different stages of the disease course,and the number of burn patients with anxiety,depression and PTSD showed a downward trend with the course of disease.The RSES score at the early rehabilitation stage was positively correlated with SAS score(rs=0.412,P=0.013),SDS score(rs=0.347,P=0.038)and PCL-C score(rs=0.447,P=0.006)at the early stage of disease,but not with SAS,SDS,or PCL-C scores at the early and late rehabilitation stages(all P＞0.05).There were no correlations between PSSS score at the early rehabilitation stage and SAS,SDS,or PCL-C scores at the early stage of disease or SAS or PCL-C scores at the early stage of rehabilitation(all P＞0.05),but there were negative correlations between PSSS score at the early rehabilitation stage and SDS score at the early stage of rehabilitation(r=-0.430,P=0.009)and SAS score(r=-0.467,P=0.004),SDS score(r=-0.483,P=0.003),and PCL-C score(rs=-0.351,P=0.036)at the late stage of rehabilitation.Conclusion Anxiety,depression,and PTSD are observed in patients with deep burns in special areas at different stages of the disease.A high level of self-esteem is associated with an increased risk of mental problems at early stage of burns.Conversely,a high level of social support is associated with a reduced likelihood of mental problems at late stage of rehabilitation.

Objective To explore the clinical efficacy and prognostic factors of YL-1 type hard channel trepanation and drainage combined with stereotactic treatment for hypertensive intracerebral hemorrhage.Methods A retrospective study was conducted on 110 patients with hypertensive intracerebral hemorrhage at the Cerebrovascular Disease Center of the First People's Hospital of Suzhou from August 2019 to October 2022.The observation group(55 cases)received YL-1 type hard channel drilling and drainage combined with stereotactic treatment,while the control group(55 cases)received simple YL-1 type hard channel drilling and drainage.The perioperative indicators,neurological damage,and prognosis of the two groups of patients were compared;Using multiple Logistic regression analysis to identify the prognostic factors affecting patients.Results The perioperative indicators,neurological damage,and prognosis of the observation group were better than those of the control group(P＜0.05);The admission NIHSS score(OR=2.504,P＜0.05),simple minimally invasive drilling and drainage(OR=1.881,P＜0.05),disease duration＞24 hours(OR=2.782,P＜0.001),and ventricular rupture(OR=2.252,P＜0.05)are risk factors for poor prognosis in patients.Conclusion The prolongation of the patient's disease course,ventricular rupture,and severe neurological damage are associated with poor prognosis.Combining stereotactic minimally invasive surgery has a positive significance for improving the prognosis of patients with cerebral hemorrhage.

Tropane alkaloids (TAs) are a class of anticholinergic drugs widely used in clinical practice and mainly extracted from plant, among which Atopa belladonna is the main commercial drug source. It is of great industrial value to obtain TAs in large quantities by plant metabolic engineering. In TAs pathway, cytochrome oxidase CYP82M3 catalyze the synthesis of tropinone and then tropinone reductase I (TRI) compete with TRII for tropinone to form tropine leading to the TAs synthesis (drainage). In this study, based on the "increasing flow and drainage" metabolic engineering strategy, two genes, namely HnCYP82M3 and DsTRI from Hyoscyamus niger and Datura stramonium, respectively, were overexpressed in the hair roots of A. belladonna, with a view to promote the TAs accumulation. The HnCYP82M3 gene was cloned from the root of H. niger, and it encoded amino acid with 91.7% sequence identity with AbCYP82M3 from A. belladonna. Overexpression of HnCYP82M3 alone did not affect the content of TAs in hair roots of A. belladonna, indicating that CYP82M3 was not a key enzyme in TAs biosynthesis. Simultaneous overexpression of HnCYP82M3 and DsTRI greatly promoted the accumulation of the three TAs, and the contents of hyoscyamine, anisodamine and scopolamine were 4.97 times, 2.83 times and 2.19 times that of the control, respectively, and the increase amplitude was greater than that of single overexpression of DsTRI. This study showed that the "increasing flow and drainage" strategy of enzyme genes co-expression at branch points was a promising metabolic engineering method to effectively improve the biosynthesis of TAs in A. belladonna, and laid a theoretical and technical foundation for the large-scale industrial acquisition of TAs.
