Cardiotocography (CTG) is a non-invasive and important tool for diagnosing fetal distress during pregnancy. To meet the needs of intelligent fetal heart monitoring based on deep learning, this paper proposes a TWD-MOAL deep active learning algorithm based on the three-way decision (TWD) theory and multi-objective optimization Active Learning (MOAL). During the training process of a convolutional neural network (CNN) classification model, the algorithm incorporates the TWD theory to select high-confidence samples as pseudo-labeled samples in a fine-grained batch processing mode, meanwhile low-confidence samples annotated by obstetrics experts were also considered. The TWD-MOAL algorithm proposed in this paper was validated on a dataset of 16 355 prenatal CTG records collected by our group. Experimental results showed that the algorithm proposed in this paper achieved an accuracy of 80.63% using only 40% of the labeled samples, and in terms of various indicators, it performed better than the existing active learning algorithms under other frameworks. The study has shown that the intelligent fetal heart monitoring model based on TWD-MOAL proposed in this paper is reasonable and feasible. The algorithm significantly reduces the time and cost of labeling by obstetric experts and effectively solves the problem of data imbalance in CTG signal data in clinic, which is of great significance for assisting obstetrician in interpretations CTG signals and realizing intelligence fetal monitoring.

Small cell lung cancer (SCLC) is the thoracic malignant tumor and accounts for about 15% of lung malignancies and transfer often occurs by the time of diagnosis. Extensive stage-small cell lung cancer (ES-SCLC) accounts for about 2/3 of all SCLC. For many years, radiotherapy has occupied an important position in the treatment of SCLC, especially in the treatment of ES-SCLC, because SCLC is more sensitive to radiotherapy. However, in recent years, immune checkpoint inhibitor has shown more excellent antitumor activity in the treatment of ES-SCLC and become the mainstream argument for the treatment of ES-SCLC. However, will radiotherapy be buried by the times among the therapeutic approaches for ES-SCLC? In this article, we will review the clinical progress of radiotherapy, immunotherapy and combination therapy for ES-SCLC.

Objective:To explore the factors influencing adherence to voice therapy among patients with voice disorders in China. Methods:Patients with voice disorders who visited the Voice Therapy Center at Sun Yat-sen Memorial Hospital, Sun Yat-sen University, from February to May 2022 were enrolled in the study. Adherence was assessed using the URICA-Voice scale, while influencing factors were assessed through the Voice Handicap Index（VHI） scale and a general information questionnaire. Correlation analysis was conducted using univariate and multivariate logistic regression analysis. Results:A total of 247 patients were included in the study, comprising 57 males（23.08%） and 190 females（76.92%）. The results revealed that: ①Female patients demonstrated higher likelihood of being in the contemplation stage（OR=0.22） compared to males. ②Patients with a monthly family income per capita>6 000 yuan were more likely to be in the contemplation stage than those with<3 000 yuan with an OR = 13.94. ③High vocal-demand occupations increased contemplation stage probability（OR=7.70） compared to moderate-demand occupations. ④Residence within 30-minute commute predicted action/maintenance stages（OR=7.14） versus≥60-minute commute. ⑤Patients whose occupations had high voice demands were more likely to be in the action and maintenance stages than those with average voice demands, with an OR of 16.20. Conclusion:Gender, monthly family income per capita, occupational voice demands, and distance to the hospital significantly impact the URICA-Voice compliance stages of patients. Patients who are female, have higher family income, have occupations with high voice demands, and live closer to the hospital exhibit higher compliance with voice training.

Atherosclerosis and its complications are one of the diseases with the highest incidence and mortality in the world,and its early diagnosis and treatment are very important.At present,a variety of physiological and biochemical indicators have been used to diagnose atherosclerosis.However,the accuracy and ease of use of existing diagnostic indi-cators still cannot meet the clinical needs,and new,reliable and easy to measure biomarkers for early diagnosis and judg-ment of atherosclerosis and the risk of serious cardiovascular and cerebrovascular events caused by atherosclerosis are still very scarce.This article summarized the latest research progress of biomarkers related to atherosclerosis,such as hematol-ogy,genetics and omics,in order to provide basis for early diagnosis and treatment of atherosclerosis and related cardiovas-cular and cerebrovascular diseases induced by atherosclerosis.

Nonalcoholic steatohepatitis （NASH） is a chronic liver disease with the main pathological features of hepatic steatosis， inflammatory cell infiltration， and interstitial fibroplasia， and it is an important risk factor for liver fibrosis， liver cirrhosis， and hepatocellular carcinoma. NOD-like receptor protein 3 （NLRP3） inflammasome is the core of innate immunity， and the abnormal activation of NLRP3 inflammasome is closely associated with the development and progression of NASH， which involves multiple links such as inflammatory response and oxidative stress. A large number of studies have shown that the active ingredients of traditional Chinese medicine （TCM） and TCM compound prescriptions can improve oxidative stress， regulate lipid metabolism， and alleviate liver inflammation by regulating NLRP3 inflammasome. TCM treatment applied in clinical practice has achieved a good therapeutic effect， while inflammasome is one of the key pathways or targets for TCM in improving NASH. This article reviews the mechanism of action of NLRP3 inflammasome in NASH and the research advances in TCM intervention of NLRP3 inflammasome， in order to provide ideas for the clinical TCM treatment of NASH， as well as reference targets and research directions for the research and development of new TCM drugs.

Objective:To integrate the symptom management experiences of patients with acute decompensated heart failure (ADHF), so as to provide a basis for developing symptom management measures.Methods:Qualitative or mixed studies on the symptom management experience of ADHF patients included from establishment of the database to September 2024, were electronically retrieved in PubMed, CINAHL, Cochrane Library, Web of Science, Embase, EBSCO, China National Knowledge Infrastructure, WanFang Data, VIP, China Biomedical Database and other Chinese and English databases and gray literature databases. The quality of the literature was evaluated using the Critical Appraisal Skills Programme developed by the Center for Evidence-Based Medicine at the University of Oxford. The results were synthesized through the aggregative integration method.Results:A total of 14 papers were included. Thirty-four findings were distilled into eight categories and three integrative findings, namely, the multiple challenges posed by symptoms (complex and multiple symptomatic somatic experiences, symptom-induced mood changes, and reduced family and social engagement), the unmet needs of patients (insufficient healthcare resources, insufficient supply of discharge services provided by healthcare organizations, and lack of knowledge), and the co-existence of positive and negative coping styles (negative coping styles in symptomatic distress, positive debugging and diversified coping in symptomatic distress) .Conclusions:ADHF symptoms severely affect patients' physical, psychological, and social function. Healthcare professionals should focus on the unmet needs of patients with ADHF and explore patient-engaged models of active symptom management.

BACKGROUND:Slow bone repair and poor bone formation quality are still problems during masquelet technique in the treatment of large segment bone defects.H-type vessels can induce osteogenesis,enhance the local angiogenesis and osteogenesis coupling,and promote bone repair.However,there are few reports on the role of H-type blood vessels in the bone induced membrane.OBJECTIVE:To construct a large segment bone defect model of SD rat tibia,observe the expression characteristics of H-type blood vessels in the bone induced membrane,then to identify the expression peak point of H-type blood vessels in the bone induced membrane and determine the optimal period of bone grafting.METHODS:Sixty SD rats were randomly divided into a control group(n=30)and a model group(n=30)by random number table method.The two groups were further divided into three subgroups at 4,6,and 8 weeks after bone cement implantation,with 10 rats in each group.A 4 mm bone defect model of the right tibia was constructed in both the control and the model groups.Polymethyl methacrylate bone cement was implanted in the model group to induce bone biomembrane formation,while bone cement was not implanted in the control group.At 4,6,and 8 weeks after bone cement implantation,6 rats were randomly selected at each time point.The bone induction membrane tissue was cut from the model group,and the non-bone soft tissue of the corresponding part was cut from the control group.The dynamic expressions of H-type blood vessels in the bone induced membrane were identified by immunofluorescence.The morphological changes of the bone induced membrane were observed by hematoxylin-eosin staining.The formation of blood vessels in the bone induced membrane was observed by angiography.The expression levels of osteoblast-specific transcription factor in the bone induced membrane were detected by immunohistochemistry.Four rats remained at each time point.In the model group,the bone induced membrane was cut open and the bone cement was removed and autologous coccyx was implanted.In the control group,autologous coccyx was implanted in the bone defect area.Micro-CT evaluation of the tibial defect was performed 8 weeks after bone grafting.RESULTS AND CONCLUSION:(1)Immunofluorescence staining showed that the expression of H-type vessels in the model group was most obvious 6 weeks after bone cement implantation,and the expression of H-type vessels in the model group at each time point after bone cement implantation was higher than that in the control group(P＜0.05).(2)Hematoxylin-eosin staining and angiography showed that the number and volume of new blood vessels at each time point after bone cement implantation in the model group were greater than those in the control group(P＜0.05).The order of the number and volume of new blood vessels in the model group was:8 weeks after bone cement implantation＞6 weeks after bone cement implantation＞4 weeks after bone cement implantation.(3)Immunohistochemical staining showed that the positive expression of osteoblast-specific transcription factors at each time point after bone cement implantation in the model group was higher than that in the control group(P＜0.05),and the positive expression of osteoblast-specific transcription factors in the model group was most obvious 6 weeks after bone cement implantation.(4)Micro-CT detection showed that the bone repair effect of the three subgroups in the model group was significantly better than that of the corresponding subgroups in the control group,and the bone repair effect of the subgroup in the model group 6 weeks after bone cement implantation was better than that of the subgroups 4 and 8 weeks after bone cement implantation.The results indicate that H-type blood vessels are dynamically expressed in the bone induced membrane and reached a peak 6 weeks after bone cement implantation.Good bone repair effects can be obtained by the bone induced membrane bone grafting 6 weeks after bone cement implantation.
