Clinical and epidemiological studies have demonstrated that patients with MMA have a higher prevalence of immune-related diseases, suggesting that immune factors play an important role in the occurrence and progression of MMA. This paper aims to review the correlation between MMA and immune-related diseases such as infections, vasculitis, and autoimmune diseases, and explore the potential mechanisms of immune-related diseases involved in the pathogenesis of MMA.

Objective To observe the effect of vericiguat on improvement of ventricular remodeling index, serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) level and New York Heart Association (NYHA) cardiac function classification in patients with heart failure with reduced ejection fraction (HFrEF). Methods A total of 100 patients with HFrEF who were admitted to the hospital from January 2023 to March 2023 were selected for a prospective study, and they were randomly divided into the observation group and the control group, with 50 patients in each group. The control group was given shakubatravalsartan sodium tablets, metoprolol succinate sustained-release tablets, spironolactone tablets, dapagliflozin tablets combined with furosemide orally, while the observation group was given vericiguat orally in addition to the control group. A total of three months were followed up, and the changes in NT-proBNP, left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), and NYHA cardiac function classification before and after treatment were compared between the two groups. Results Compared with before treatment, LVEF, LVESD, LVEDD and NT-proBNP in the two groups were significantly improved after treatment, and the differences were statistically significant (P<0.05). There was no significant difference in LVEF, LVESD, LVEDD and NT-proBNP between the two groups before and after treatment (P>0.05). The total effective rate of the patients in the observation group [94.0%(47/50)] was significantly higher than that in the control group [76.0%(38/50)], and the difference was statistically significant (P<0.05). Conclusion Vericiguat has a good curative effect on HfrEF, which can improve patients' exercise tolerance and improve NYHA cardiac function classification. [ABSTRACT FROM AUTHOR]

Objective To explore the sleep quality and influencing factors in patients with chronic cerebral ischemia represented by Moyamoya disease without stroke, and analyze the correlation between sleep quality and postoperative ischemic symptoms and stroke. Methods A total of 138 Moyamoya disease patients without stroke confirmed by imaging were prospectively included, and clinical data including gender, age, initial symptoms, and comorbidities were collected. The Pittsburgh sleep quality index scale was used to assess the patient’s preoperative sleep quality, and the HAMD-17 and MoCA were used to evaluate preoperative depression status and cognitive function, respectively. Clinical characteristics, cognitive function, and depression status were compared between the normal sleep quality group and the decreased sleep quality group. Multivariate logistic regression analysis was used to analyze the risk factors affecting patient’s sleep quality. Patients who underwent cerebral revascularization were followed up to determine the differences in the incidence of postoperative ischemic events and stroke between the normal and decreased sleep quality groups. Results A total of 52(37.7%) patients with Moyamoya disease experienced decreased sleep quality. Patients with decreased sleep quality were older (P=0.002), had poorer cognitive function (P=0.017), and exhibited more significant depressive tendencies (P=0.012) than those with normal sleep quality. Multivariate analysis suggested that age (OR 1.05, 95%CI 1.01-1.09, P=0.021) and HAMD-17 score (OR 1.11, 95%CI 1.01-1.23, P=0.035) were independent risk factors for decreased sleep quality. Additionally, during the postoperative follow-up, patients with a preoperative decrease in sleep quality had a higher incidence of ischemic symptoms (P=0.008). There was no significant difference in stroke recurrence rates between the two groups. Conclusions Patients with Moyamoya disease without stroke have a higher proportion of sleep disorders, which are associated with postoperative ischemic events, highlighting the need for enhanced assessment and intervention of sleep quality in clinical practice.

Objective: To explore the relationship study between serum myelin basic protein (MBP), lactate dehydrogenase (LDH) to albumin (ALB) ratio (LAR), ALB to globulin (GLB) ratio (AGR) and postoperative brain injury and prognosis in patients with glioma. Methods: 90 cases of patients with glioma who received surgical treatment admitted to Department of Neurosurgery, Affiliated Hospital of Xuzhou Medical University from January 2017 to June 2019 were retrospectively selected, and they were divided into mild brain injury group with 51 cases, moderate brain injury group with 24 cases and severe brain injury group with 15 cases according to the score of the Glasgow Coma Scale (GCS) after surgery. After 3 years of follow-up, they were divided into death group and survival group according to the prognosis. Clinical data were collected, and serum MBP, LAR and AGR before surgery were detected. Spearman correlation was used to analyze the correlation between GCS score and serum MBP, LAR and AGR in patients with glioma, and multivariate logistic regression was used to analyze the influencing factors of death in patients with glioma. Results: Serum MBP and LAR in the mild, moderate and severe brain injury groups were increased successively, while AGR was decreased successively (P< 0.05). Spearman correlation analysis showed that postoperative GCS score in patients with glioma was negatively correlated with serum MBP and LAR, and positively correlated with AGR (all P<0.05). After 3 years of follow-up, the mortality rate of 90 cases of patients with glioma was 35.56% (32/90). Multivariate logistic regression analysis showed that World Health Organization (WHO) grade III, incomplete resection range, decreased postoperative GCS score and elevated MBP and LAR were the independent risk factors for death in patients with glioma, and elevated AGR was the independent protective factor (P<0.05). Conclusion: Serum MBP, LAR and AGR in patients with glioma are closely related to postoperative brain injury and poor prognosis, which may be used as indicators to evaluate postoperative brain injury and prognosis in patients with glioma.

Electrocardiogram(ECG) monitoring is a routine monitoring method in clinical practice. By observing ECG activities and ECG waveform changes, myocardial damage, myocardial ischemia and electrolyte disorder could be detected. It is clinically significant to detect QRS complex in ECG. This paper proposes an algorithm for QRS complex detection using an adaptive threshold method based on window maximum or minimum value method, which includes detection of R-wave morphology in ECG, and verification of R-wave location accuracy rate (97. 63% ) by MIT-BIH arrhythmia database. On the basis of R-wave detection, the maximum or minimum value method and slope limit method are used to search for Q- and S-wave. After QRS complex positioning is completed, P- and T- wave are detected, and located according to their morphological characteristics. [ABSTRACT FROM AUTHOR]

The indicator diagram of the pumping unit visually shows the working conditions of the pumping unit. However, the actual working conditions show typical long-tailed distribution characteristics, and the categories are seriously unbalanced. Traditional methods cannot accurately identify small categories of working conditions, and cannot obtain accurate identification of underground working conditions. Aiming at this problem, a cost-sensitive active learning algorithm based on distribution-driven multi-class long-tail data (CALA) is proposed. First, considering the characteristics of data distribution, the optimal number of clusters for the data is determined by minimizing the cost as the optimization objective. Second, the optimal number of clusters obtained before is updated by adding the pre-classification error cost. Then, a classifier is constructed by integrating the classification models. Finally, balance the data distribution iteratively. Using the real indicator diagram data of an oil field to test, the significant experimental analysis proves that CALA has better performance in the diagnosis of small categories of working conditions.

Aiming at the problems of uneven distribution and low coverage when nodes are randomly deployed in wireless sensor network (WSN), a hybrid particle swarm-butterfly algorithm (HPSBA) is proposed for node deployment optimization. Firstly, logistic mapping and adaptive adjustment strategies are designed to control parameter values, so that the optimization speed, convergence accuracy and global search capability of HPSBA are improved. Then, four benchmark functions are used to analyze the performance of HPSBA. The simulation results show that HPSBA has higher optimization accuracy, faster optimization speed, and better stability. Finally, HPSBA is used in WSN node deployment optimization and compared with other six typical algorithms such as PSO, BOA, IGWO and so on. The results show that HPSBSA has higher coverage rate, which can effectively reduce the redundancy of nodes and prolong the survival time of WSN. [ABSTRACT FROM AUTHOR]

Polybutylene adipate terephthalate (PBAT) has emerged as a potential biodegradable mulching film in recent years. Taking the tomato cultivation as the research object, three treatments were selected for the biodegradation characteristics, including the ordinary PE mulching film (T1), PBAT/ straw-based biodegradable mulching film (T2), and non-mulching film (T3) in Jiangsu Province of China. The microstructure, morphology, and mechanical strength of the film were characterized during degradation. Meanwhile, the effects of mulching film on the tomato plant height, stem diameter, and yield were clarified to determine the comprehensive benefits of biodegradable mulching film. The results show that there were a series of changes in the physical and chemical properties of the PBAT/straw-based biodegradable mulching film during the 120 d mulching period. The Fourier infrared spectrum showed that the molecular chain of the degradable mulching film was broken under the action of soil microorganisms, light, and water. The X-ray diffraction pattern exhibited that the crystalline area of degradable mulch was destroyed gradually, whereas, the amorphous area increased relatively. Thermogravimetric analysis indicated that there were a few Tmax changes, T0 increase, and a decrease in the carbon residue rate, indicating the thermal properties of the degraded mulching film. The water contact angle confirmed that the degradable mulching film was degraded in the field. Scanning electron microscopy (SEM) images illustrated that there was an uneven degradation of mulching film. The tensile strength and elongation decreased gradually at the break of the degradable film, as the film covering time increased. The mechanical property test verified that the PBAT/ straw-based biodegradable mulching film was degraded gradually in the field with a slow degradation rate after 120 days. Moreover, there was a better effect of degradable mulching film on the tomato growth, compared with the conventional PE and non-mulching film group, in terms of the plant height and stem diameter of tomato plants. The yield of tomato fruit in the degradable and the PE mulching group was equivalent to 667 m2 , which was 13.5% and 15.0% higher than that in the non-mulching film group, respectively. The excellent ecological benefits and the higher recovery cost-saving were achieved for the PBAT/straw-based fully biodegradable mulching film, although the product cost was relatively high. In general, the PBAT/ straw-based fully biodegradable mulching film can be widely expected to serve a remarkable effect on tomato cultivation in the greenhouse. The degradation cycle can be further explored to accelerate the spread the promotion of the degradable mulching. [ABSTRACT FROM AUTHOR]

The spiral is a structure that often appears in nature. The spiral structure has attracted the attention of researchers in the field of intelligent optimization algorithms due to its special trajectory and natural convergence. Based on the spiral dynamic optimization algorithm（SDA）,this paper proposed an improved spiral algorithm（MSPO） based on combined spiral and FDB selection strategy. It overcame the shortcomings of the SDA, greatly reduced the time complexity, simplified the calculation process, and improved the universality and convergence accuracy. Finally, it carried out experiments on 8 representative benchmark functions. Compared with the experimental results in references, MSPO shows better performance in convergence accuracy, speed and robustness. At the same time, it was applied to the optimization of the size of 10-bar and 25-bar continuous truss structures. Simulation experiments show that MSPO can well solve this type of structural optimization problem, compared with other commonly used algorithms. [ABSTRACT FROM AUTHOR]
