Planning an adaptive reuse development of underutilized urban underground infrastructures: A case study of Qingdao, China
•Adaptive reuse strategies of underutilized urban underground infrastructures (UUIs).•Adaptive reuse patterns of underutilized UUIs derived from the exemplary practices.•Planning layout approaches for adaptive reuse development of underutilized UUIs.•Underutilized UUIs are a vital component of built capital for urban sustainability.
Urban underground infrastructures (UUIs) are a vital component of built capital for urban sustainability. However, many cities are now home to a multitude of disused or underutilized UUIs, not least aged purpose-built underground facilities, causing a waste of valuable underground space resource assets. In the process of urban renewal, adaptive reuse can be an attractive solution to breathe new life into underutilized UUIs, while addressing some of the modern problems of the built environment by an economically feasible means. Nevertheless, there is a prevalent absence in the current literature of the overarching planning and decision-making approaches for an adaptive reuse development of underutilized UUIs. With the intention of addressing this shortfall, this paper first lays out development strategies, then sets the generic patterns for adaptive reuse of disused or underutilized UUIs. Taking the city of Qingdao, China as a case study, detailed planning and decision-making approaches with the aid of multi-source data and spatial analysis tools are presented. It is anticipated that the findings of this research will assist the adaptive reuse development of UUIs in providing theoretical guidance and empirical evidence, thereby enhancing the role of urban underground space use in contributing to urban revitalization and urban sustainability.

Case Report: Telitacicept in severe myasthenia gravis: a case study with multiple autoantibodies
Multi-antibody-positive myasthenia gravis (MG) presentations are relatively rare, often found in older patients, and generally predict a poor prognosis. We report a case of a female patient with generalized MG, testing positive for Titin antibodies (Titin-Ab), ryanodine receptor antibodies (RyR-Ab), and acetylcholine receptor antibodies (AChR-Ab), and resistant to acetylcholinesterase inhibitors. Following unsuccessful traditional therapies, she received Telitacicept, leading to significant improvements. This case underscores Telitacicept’s potential efficacy for similar patients and offers insights into the clinical characteristics of multi-antibody MG.

Quantitative evaluation of the contribution of underground space to urban resilience: A case study in China
Urban underground space (UUS) development has been acknowledged as a positive contribution to urban resilience (UR). Such contribution has been qualitatively addressed in recent years, but only quantitatively discussed in few studies. Quantitative evaluation methods for UR are widely used in China and around the world, but the role of underground space is barely included. This paper provides a way to bridge this gap on the city scale. A UR evaluation framework was carefully constructed that covers the basic aspects and elements of UR. The contributions of UUS to UR were identified and integrated into the UR evaluation framework, and the measurement methods for each indicator related to UUS were determined. A case study of 19 sample cities in China were conducted using the integrated evaluation model. Correlation analysis and clustering analysis were further adopted to interpret the evaluation results, mainly with three indicators reflecting the level of UUS development, namely UUS area (m2), UUS density (104 m2/km2) and UUS area per capita (m2/person). The results showed a strong correlation between UUS area and UR. The average proportion of UR provided by UUS in the 19 sample cities was 16.46%, while the maximum figure reached 29.20%. The sample cities were clustered into four categories based on the relationship between the proportion of UR provided by UUS, UUS area, and GDP per capita, where both high and low UUS area tend to provide less proportion of resilience than the medium UUS area. Corresponding suggestions for UUS utilization were proposed to assist cities in achieving urban resilience.

Visualization Method of Key Knowledge Points of Nursing Teaching Management System Based on SOM Algorithm and Biomedical Diagnosis
The traditional nursing teaching knowledge point recommendation algorithm based on collaborative filtering is difficult to deal with the problem of data sparsity, while the traditional recommendation algorithm based on matrix decomposition has poor scalability in dealing with high-dimensional data, and their recommendation results are only determined according to the prediction score, resulting in low recommendation accuracy. In view of this, a nursing teaching knowledge point recommendation method based on a SOM neural network and ranking factor decomposition machine is proposed. Firstly, the SOM neural network is used to cluster users based on users’ academic background information, then the partial order relationship of nursing teaching knowledge points is constructed by using users’ explicit and implicit web access behavior, and finally, the factor decomposition machine is used as the ranking function to classify users’ academic background web access behavior, borrowing nursing teaching introduction text, and other characteristic information were modeled, and the peer-to-peer ranking learning algorithm was used to accurately recommend nursing teaching knowledge points. Experimental results show that the proposed method can effectively alleviate the problem of data sparsity and improve the accuracy and efficiency of recommendations.

Association between sugar‐sweetened beverages and type 2 diabetes: A meta‐analysis
Aims/Introduction Many studies have been carried out to examine the association between sugar‐sweetened beverages and the incident of type 2 diabetes, but results are mixed. The aim of the present study was to estimate the association between sugar‐sweetened beverage intake and the risk of type 2 diabetes. Materials and Methods PubMed, Springer Link and Elsevier databases were searched up to July 2014. Prospective studies published on the association between sugar‐sweetened beverage intake and the risk of type 2 diabetes were included. The pooled relative risks (RRs) and 95% confidence intervals (CIs) for highest versus lowest category of sugar‐sweetened beverages were estimated using a random‐effects model. Results The pooled effect estimate of sugar‐sweetened beverage intake was 1.30 (95% confidence interval [CI] 1.21–1.39) for type 2 diabetes; stratified by geographic region of the studies, the pooled effect estimates were 1.34 (95% CI 0.74–2.43), 1.30 (95% CI 1.20–1.40), 1.29 (95% CI 1.09–1.53) in Asia, the USA and Europe,respectively; the pooled effect estimates were 1.26 (95% CI 1.16–1.36) with adjusting body mass index and 1.38 (95% CI 1.23–1.56) without adjusting body mass index. Conclusions Our findings suggested that sugar‐sweetened beverage intake was associated with an increased risk of type 2 diabetes, and the association was attenuated by adjustment for body mass index. Specifically, the associations were also found to be significantly positive in the USA and Europe. Our findings suggested that sugar‐sweetened beverages intake was associated with an increased risk of type 2 diabetes. Specifically, the associations were also found significant positive in USA, Europe and independent of body mass index.

Fluid–Structure Interaction of a Propeller Under a Two-Scale Inflow Field
The interaction between the ship hull and the propeller’s rotational motion causes the propeller to operate under non-uniform inflow conditions. In reality, the ship’s effective wake constitutes a complex nonlinear superposition of multiple wave numbers. However, existing studies often neglect these multi-scale interactions. In this work, Unsteady Reynolds-Averaged Navier–Stokes (URANS) simulations with a two-scale inflow model are conducted to investigate the fluid–structure interaction of a propeller under multi-scale inflow. The model introduces large-scale and small-scale Fourier modes together with transverse perturbations, allowing systematic variation of inflow characteristics. The results reveal that large-scale modes amplify unsteady thrust fluctuations and enhance vortex fragmentation, while small-scale modes produce similar but weaker effects, mainly influencing the high-frequency components of unsteady thrust. In contrast, transverse perturbations reduce inflow non-uniformity, effectively suppress single blade thrust fluctuations, and preserve the coherent vortex structures of the wake. This study highlights the importance of multi-scale effects in the unsteady hydrodynamic characteristics of marine propellers and provides useful insights for the optimization of propeller design and energy-saving devices.

Coil embolization of anomalous systemic artery to the left lower lobe in an asymptomatic adult: a case report
Background
Anomalous systemic artery to the left lower lobe (ASALLL) is a rare congenital anomaly. The primary symptoms include hemoptysis and lung infection, though some patients may remain asymptomatic. Currently, there is no consensus on the indications for treatment or the optimal choice of therapy for this condition. This case presents a case of an asymptomatic adult who underwent coil embolization.
Case presentation
A 48-year-old male was admitted to our hospital due to the discovery of a space-occupying lesion in the left hilum. The contrast-enhanced pulmonary computed tomography scan was used to diagnose the patient with an anomalous systemic artery to the left lower lobe. We performed coil embolization on this patient, who underwent a follow-up computed tomography angiography of the pulmonary and bronchial arteries one year later. Result demonstrated complete embolization of the abnormal systemic arteries and a slight reduction in the volume of the left lower lobe.
Conclusion
Coil embolization is a safe and minimally invasive procedure for adult patients who have an anomalous systemic artery to the left lower lobe.

The Prognostic Value of Preoperative Neutrophil-to-Lymphocyte Ratio in Resected Patients with Pancreatic Adenocarcinoma
Purpose
This research aims to analyze neutrophil-to-lymphocyte ratio (NLR) for resectable pancreatic ductal adenocarcinoma (PDAC) patients and reveal its predictive value.
Methods
We enrolled 389 pancreatic adenocarcinoma patients who had undergone curative surgery between January 1, 2008 and August 15, 2015 in Jiangsu Provincial People’s Hospital, and they were followed up until December 20, 2016. Among them, 219 patients had definite recurrence record in our hospital. The appropriate cutoff value for the NLR was obtained from X-tile software. The association between qualitative variables and NLR was analyzed by Chi-square test or Fisher’s exact test, and for quantitative values, the association was analyzed by independent Student’s
t
test. Additionally, survival analysis was performed by Kaplan–Meier plots. Independent prognostic factors were found according to Cox regression analysis.
Results
Based on univariate analysis, the elevated preoperative NLR had an important influence on the decreased recurrence-free survival (RFS) (8.2 vs. 14.9 months) and overall survival (OS) (13.7 vs. 22 months), and this result also counted in the multivariate analysis. Regarding OS, both patients with or without postoperative chemotherapy can obtain benefits from low NLR according to subgroup analysis. Stage I and II pancreatic adenocarcinoma patients can get longer OS and RFS from low NLR, while patients with stage III cancer cannot. Regarding recurrence site, high NLR level was also related to distant metastasis (
P
= 0.02).
Conclusion
Preoperative NLR level could be a useful prognostic indication for resectable pancreatic adenocarcinoma patients.

Initialization Algorithms of a Rigid–Flexible Coupling Fluid–Structure Interaction System by Considering Length-and-Area Constraints
Rigid–flexible coupling fluid–structure interaction systems are expected to be future solutions for reducing energy lost in water. The dynamics of these systems is usually investigated via numerical simulations. However, in existing numerical works there is no accurate algorithm for the initialization of the flexible filament, which ensures both the length and area constraints, leading to inaccurate results or even severe numerical instabilities. We propose two alternative initialization algorithms, respectively, the “Trapezoidal arrangement” and the “Quartic curve arrangement”. The performances of both of these two algorithms are investigated in numerical simulations by using the immersed boundary method. The motion responses and force characteristics of the flexible filament are analyzed carefully, verifying the capability of the proposed algorithms. Specifically, “Quartic curve arrangement” is further recommended due to its good property of convergence.
