Objective::To investigate the correlation between maternal serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and gestational duration in pregnant women with pulmonary hypertension (PH).Methods::The study included pregnant individuals with PH stemming from mitral valve stenosis and mitral valve regurgitation (post-capillary PH) or pulmonary arterial hypertension (pre-capillary PH) who were admitted to Guangdong Provincial People’s Hospital between January 1, 2014 and December 31, 2020. In this retrospective cohort study, maternal serum NT-proBNP levels during pregnancy, along with other clinical data, were obtained from structured electronic medical records. These data included gestational age at delivery, echocardiographic parameters, laboratory findings, gestational duration, delivery mode, and other relevant clinical variables. Univariate and multivariate regression analyses were conducted to assess the association between NT-proBNP levels and gestational duration. Adjustments were made for potential confounding factors, and curve fitting and threshold effect analysis were employed to identify tangent points. Furthermore, stratified analyses were performed based on tricuspid regurgitation velocity, maternal age, and parity.Results::A total of 64 patients with post-capillary PH and 74 patients with pre-capillary PH were included in this study. Among patients with post-capillary PH, the results of multivariate regression analysis indicated a significant association between maternal NT-proBNP levels and gestational duration (β = -0.03, 95% confidence interval (CI) -0.05 to 0.00, P = 0.02). The fitted curve demonstrated a negative correlation between maternal NT-proBNP levels and gestational duration, with a significant break point at 379.9 ng/L ( P < 0.05). In the post-capillary PH group, the stratified analysis revealed a regression coefficient of -0.05 (95% CI:-0.06 to -0.04, P = 0.001) in patients with a tricuspid regurgitation velocity >340 mm/s. For patients >35 years old, the regression coefficient was -0.03 (95% CI -0.06 to -0.01, P = 0.02). In multiparous women, the regression coefficient was -0.03 (95% CI-0.06 to 0.00, P = 0.03). Conclusion::In pregnant women with pulmonary hypertension, maternal NT-proBNP levels are associated with gestational duration, particularly with an increased risk of preterm labor.

Alzheimer''s disease (AD) has brought to us huge medical and economic burdens, and so discovery of its therapeutic drugs is of great significance.In this paper, we utilized knowledge graph embedding (KGE) models to explore drug repurposing for AD on the publicly available drug repurposing knowledge graph (DRKG).Specifically, we applied four KGE models, namely TransE, DistMult, ComplEx, and RotatE, to learn the embedding vectors of entities and relations on DRKG.By using three classical knowledge graph evaluation metrics, we then evaluated and compared the performance of these models as well as the quality of the learned embedded vectors.Based on our results, we selected the RotatE model for link prediction and identified 16 drugs that might be repurposed for the treatment of AD.Previous studies have confirmed the potential therapeutic effects of 12 drugs against AD, i.e., glutathione, haloperidol, capsaicin, quercetin, estradiol, glucose, disulfire, adenosine, paroxetine, paclitaxel, glybride and amitriptyline.Our study demonstrates that drug repurposing based on KGE may provide new ideas and methods for AD drug discovery.Moreover, the RotatE model effectively integrates multi-source information of DRKG, enabling promising AD drug repurposing.The source code of this paper is available at https://github.com/LuYF-Lemon-love/AD-KGE.

Knowledge graph technology has promoted the progress of new drug research and development, but domestic research starts late and domain knowledge is mostly stored in text, resulting in low rate of knowledge graph reuse.Based on multi-source and heterogeneous medical texts, this paper designed a Chinese named entity recognition model based on Bert-wwm-ext pre-training model and also integrated cascade thought, which reduced the complexity of traditional single classification and further improved the efficiency of text recognition.The experimental results showed that the model achieved the best performance with an F1-score of 0.903, a precision of 89.2%, and a recall rate of 91.5% on the self-built dataset.At the same time, the model was applied to the public dataset CCKS2019, and the results showed that the model had better performance and recognition effect.Using this model, this paper constructed a Chinese medical knowledge graph, involving 13 530 entities, 10 939 attributes and 39 247 relationships of them in total.The Chinese medical entity extraction and graph construction method proposed in this paper is expected to help researchers accelerate the new discovery of medical knowledge, and shorten the process of new drug discovery.

Objective:To analyze the curative effect of radioactive 131I therapy assisted by hyperbaric oxygen（HBO）on elderly patients with hyperthyroidism. Methods:A total of 185 elderly patients with hyperthyroidism diagnosed and treated in the First People’s Hospital of Shangqiu，Henan Province，from January 2015 to December 2019 were divided into control group（91 cases）and experimental group（94 cases）according to different treatment methods. The control group was treated with radioactive 131I，while the experimental group received HBO as an auxiliary treatment on the basis of the treatment of the control group. The World Health Organization Quality of Life Measurement Scale（WHO-QOL）was used to evaluate the quality of life. The clinical efficacy，complications，occurrence of hypothyroidism，recurrence of hyperthyroidism，thyroid hormone levels before and after treatment，and quality of life were compared between the two groups. Results:The total effective rate of treatment in the experimental group（90.43%）was significantly higher than that in the control group（76.92%， P<0.05）. After treatment，the levels of free triiodothyronine（FT3），free thyroxine（FT4），thyroglobulin autoantibodies（TGAb），and thyroid peroxidase antibodies（TPOAb）all decreased in both groups（ P<0.05），and these levels in the experimental group were significantly lower than those in the control group（ P<0.05）. After treatment，the levels of thyroid stimulating hormone（TSH）in both groups increased（ P<0.05），and the level in the experimental group was significantly higher than that in the control group（ P<0.05）. After treatment，the scores pertaining to physical health，mental state，personal belief，social relationship，environment，and level of independence in the two groups all increased（ P<0.05），and the scores in the experimental group were all significantly higher than those in the control group（ P<0.05）. The incidences of complications（3.19% vs. 5.49%）and hypothyroidism（10.64% vs. 13.19%），and hyperthyroidism recurrence rates（2.13% vs. 3.30%）in both groups were not significantly different from each other（ P>0.05）. Conclusion:HBO-assisted radioactive 131I therapy in elderly patients with hyperthyroidism can effectively increase the level of thyroid hormones，the quality of life，and treatment efficacy，without increasing the incidences of complications and hypothyroidism，and the recurrence of hyperthyroidism.

The peak period of cardiovascular disease (CVD) is around the time of awakening in the morning, which may be related to the surge of sympathetic activity at the end of nocturnal sleep. This paper chose 140 participants as study object, 70 of which had occurred CVD events while the rest hadn't during a two-year follow-up period. A two-layer model was proposed to investigate whether hypnopompic heart rate variability (HRV) was informative to distinguish these two types of participants. In the proposed model, the extreme gradient boosting algorithm (XGBoost) was used to construct a classifier in the first layer. By evaluating the feature importance of the classifier, those features with larger importance were fed into the second layer to construct the final classifier. Three machine learning algorithms, i.e., XGBoost, random forest and support vector machine were employed and compared in the second layer to find out which one can achieve the highest performance. The results showed that, with the analysis of hypnopompic HRV, the XGBoost+XGBoost model achieved the best performance with an accuracy of 84.3%. Compared with conventional time-domain and frequency-domain features, those features derived from nonlinear dynamic analysis were more important to the model. Especially, modified permutation entropy at scale 1 and sample entropy at scale 3 were relatively important. This study might have significance for the prevention and diagnosis of CVD, as well as for the design of CVD-risk assessment system.
