Typical Pulmonary Carcinoid (TPC) is defined by its slow growth, frequently necessitating surgical intervention. Despite this, the long-term outcomes following tumor resection are not well understood. This study examined the factors impacting Overall Survival (OS) in patients with TPC, leveraging data from the Surveillance, Epidemiology, and End Results database spanning from 2000 to 2018. We employed Lasso-Cox analysis to identify prognostic features and developed various models using Random Forest, XGBoost, and Cox regression algorithms. Subsequently, we assessed model performance using metrics such as Area Under the Curve (AUC), calibration plot, Brier score, and Decision Curve Analysis (DCA). Among the 2687 patients, we identified five clinical features significantly affecting OS. Notably, the Random Forest model exhibited strong performance, achieving 5- and 7-year AUC values of 0.744/0.757 in the training set and 0.715/0.740 in the validation set, respectively, outperforming other models. Additionally, we developed a web-based platform aimed at facilitating easy access to the model. This study presents a machine learning model and a web-based support system for healthcare professionals, assisting in personalized treatment decisions for patients with TPC post-tumor resection.

Heart failure (HF) is a complex, progressive disorder that is associated with substantial morbidity and mortality on a global scale. Relaxin‐2 is a naturally occurring hormone that may have potential therapeutic benefit for patients with HF. To investigate the therapeutic potential of relaxin in the treatment of patients with HF, mRNA‐0184, a novel, investigational, lipid nanoparticle (LNP)–encapsulated mRNA therapy that encodes for human relaxin‐2 fused to variable light chain kappa (Rel2‐vlk) was developed. A translational semi‐mechanistic population pharmacokinetic (PK)/pharmacodynamic (PD) model was developed using data from non‐human primates at dose levels ranging from 0.15 to 1 mg/kg. The PK/PD model was able to describe the PK of Rel2‐vlk mRNA and translated Rel2‐vlk protein in non‐human primates adequately with relatively precise estimates. The preclinical PK/PD model was then scaled allometrically to determine the human mRNA‐0184 dose that would achieve therapeutic levels of Rel2‐vlk protein expression in patients with stable HF with reduced ejection fraction. Model‐based simulations derived from the scaled PK/PD model support the selection of 0.025 mg/kg as an appropriate starting human dose of mRNA‐0184 to achieve average trough relaxin levels between 1 and 2.5 ng/mL, which is the potential exposure for cardioprotective action of relaxin.

Species richness is the most basic concept of diversity and is crucial to biodiversity conservation and sustainable fisheries. To understand the fish species richness of the Minjiang Estuary and its adjacent waters, eight documents and surveyed data were collected and compared from 1990–2021. To obtain suitable analysis data, the content of the data was compared and evaluated. Explore the suitability of data based on several criteria. Among them, the bottom trawling survey carried out in 2006–2007, and non-parametric estimation methods such as Chao 2, Jackknife 1, Jackknife 2 and Bootstrap were used to estimate the fish species richness. The results of this case show that a total of 153 species of fish were caught in the trawling survey in the fourth quarter, belonging to 14 orders, 57 families and 101 genera. The 2006–2007 cruise is more complete for studying species richness. The Estimable expectations of fish species richness are: 250 (Chao 2), 204 (Jackknief 1), 241 (Jackknief 2) and 174 (Bootstrap). The number of fish species was significantly higher in summer and autumn than winter and spring. To manage fishery resources and sustainability in the sea area of Fujian Province, biological information and stock assessment are required. This meaningful information, especially for endemic and economically important species such as can set a baseline. Once species change exceeds the baseline range, it provides decision-making basis for marine biodiversity conservation and fisheries management.

Objective To explore the effect of miR-133a-3p on the apoptosis and inflammatory response of bronchial epithelial cells infected by respiratory syncytial virus (RSV) and its regulatory effect on CD2-associated protein (CD2AP). Methods The bronchial mucosal tissue specimens from 59 children with bronchial asthma were collected as the AsP group and 59 bronchial mucosal tissue specimens from non-asthmatic children with bronchiec- tasis were selected as the NC group. RT-qPCR method was used to detect the expression of miR-133a-3p and CD2AP in the tissues. RSV infected bronchial epithelial cells (16-HBE) were used to establish a cell injury model (RSV group). miR-NC, miR-133a-3p mimics, si-NC, si-CD2AP, pcDNA-NC, pcDNA-CD2AP, miR-133a-3p mimics and pcDNA-NC, miR-133a-3p mimics and pcDNA-CD2AP were respectively transferred into 16-HBE cells infected with RSV. RT-qPCR and Western blot were used to detect the expression of miR-133a-3p and CD2AP in the cells. ELISA was used to detect the level of TNF-α, IL-6, and IL-1α. Flow cytometry was used to detect apoptosis . The dual luciferase reporter experiment was used to detect the targeting relationship between miR-133a-3p and CD2AP. Western blot method was used to detect the protein expression of cleaved-caspase-3. Results Compared with NC group, the expression of miR-133a-3p in the bronchial mucosa tissue of the AsP group was decreased (P＜0.05), and the expression of CD2AP mRNA was increased (P＜0.05). The expression of miR-133a-3p in RSV-infected 16-HBE cells was decreased (P＜0.05), and the expression level of CD2AP, TNF-α, IL-6 and IL-1α was increased (P＜0.05), the apoptosis rate and the protein level of cleaved-caspase-3 were increased(P＜0.05). Transfection of miR-133a-3p mimics or transfection of si-CD2AP into RSV-infected 16-HBE cells significantly reduced the level of TNF-α, IL-6, IL-1α, the apoptosis rate and the protein level of cleaved-caspase-3 (P＜0.05). The dual luciferase report experiment confirmed that CD2AP was the target gene of miR-133a-3p. Co-transfection of miR-133a-3p mimics and pcDNA-CD2AP significantly reversed the effects of miR-133a-3p mimics transfection on 16-HBE cell apoptosis and inflammation. Conclusions The over-expression of miR-133a-3p inhibits the inflammatory response and apoptosis of RSV-infected bronchial epithelial cells by negatively regulating the expression of CD2AP and thereby reducing cell damage.

This paper understands the personality traits and cluster types of physical education (PE) teachers in elementary schools. A total of 393 elementary PE teachers volunteered to participate in this study. The Personality Trait Questionnaire for PE teachers in elementary school was summarized and compiled on the basis of the theory of the Big Five personality traits. The researchers used the discriminant analysis method to analyze and obtain the data. The results show that the Big Five personality traits of PE teachers in elementary schools was agreeableness. Classification of the Big Five personality traits through discriminant analysis revealed a Wilk’s λ value of .199, an eigenvalue of 3.254, and 94.7% of the variance explained. Use of Ward’s minimum variance method indicated that the participants’ personalities were characterized by steady and pioneering type, sensitive and cautious type, and moderate and peaceful type. There were more males than females in the steady and pioneering type, more steady and pioneering type under the age of 30 years old, and more moderate and peaceful type with more than 16 years of work experience. In conclusion, most the personality traits of PE teachers in elementary school were agreeableness, moderate and peaceful type, which shows that most PE teachers have calm emotions, appropriate expressions of emotions, regularity, optimism, and enjoy interacting and collaborating with others.

(1) Background: The accurate diagnosis of esophageal strictures is quite critical for optimizing medical intervention. However, the diagnosis of suspicious malignant esophageal strictures with intact mucosa appearance and negative biopsy results is challenging. This study aimed to evaluate the role of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in the diagnosis of suspicious esophageal strictures. (2) Methods: We retrospectively analyzed the cases with suspicious malignant esophageal strictures that underwent EUS-FNA, with or without rapid on-site evaluation (ROSE), in our hospital from April 2017 to September 2022. Their clinical manifestations, imaging examinations, gastroscopic examinations, EUS-FNA results, and therapeutic strategies were retrospectively recorded and analyzed. (3) Results: A total of 23 patients (15 male and 8 female) were enrolled in this study. Based on EUS-FNA results, 18 patients were diagnosed with malignancies, including 16 cases of primary esophageal cancer (13 squamous carcinomas and 3 adenocarcinomas), 1 case of mediastinal cancer, and 1 case of metastatic esophageal cancer; 1 case of tuberculosis was also confirmed by EUS-FNA. Among 4 cases of ambiguous diagnosis with EUS-FNA, 1 was diagnosed with an esophageal glomus tumor after surgical removal, and 2 patients survived for several years without medical intervention, which hinted at the possibility of benign esophageal strictures. No major complications, including bleeding or perforation, were observed. (4) Conclusions: EUS-FNA may serve as a safe and effective diagnostic tool in suspicious malignant esophageal strictures with accurate specimen acquisition, especially for biopsy-negative cases.
