ObjectiveIn order to improve the recognition accuracy of named entities in medical record texts and realize the effective mining and utilization of medical record knowledge, a Bert-Radical-Lexicon(BRL) neural network model is constructed to recognize medical record entities with respect to the characteristics of medical record texts. MethodWe selected 408 medical records related to hypertension from the the Complete Library of Famous Medical Records of Chinese Dynasties and constructed a dataset consisting of 1 672 medical records by manually labeling. Then, we randomly divided the dataset into three subsets, including the training set(1 004 cases), the testing set (334 cases) and the validation set(334 cases). Based on this dataset, we built a BRL model that fused various text features of medical records, as well as its variants BRL-B, BRL-L and BRL-R, and a baseline model Base for experiments. During the model training phase, we trained the above models using the training set to reduce the risk of overfitting. We continuously monitored the performance of each model on the validation set during training and saved the model with the best performance. Finally, we evaluated the performance of these models on the testing set. ResultCompared with other models, the BRL model had the best performance in the medical records named entity recognition task, with an overall recognition precision of 90.09%, a recall of 90.61%, and the harmonic mean of the precision and recall(F1) of 90.35% for eight types of entities, including disease, symptom, tongue manifestation, pulse condition, syndrome, method of treatment, prescription and traditional Chinese medicine(TCM). Compared with the Base model, the BRL model improved the overall F1 value of entity recognition by 5.22%, and the F1 value of pulse condition entity increased by 6.92%, which was the largest increase. ConclusionBy incorporating a variety of medical record text features in the embedding layer, the BRL neural network model has stronger named entity recognition ability, and thus extracts more accurate and reliable TCM clinical information.

Objective:To compare the effects of leukocyte-poor platelet-rich plasma (Lp-PRP) and leukocyte-rich platelet-rich plasma (Lr-PRP) on dorsal wound healing in rats.Methods:Thirty-six male Sprague-Dawley rats were randomly divided into Lp-PRP group, Lr-PRP group and control group, each containing twelve rats. Venous blood was drawn and the Lp-PRP and Lr-PRP were prepared separately using a centrifugal method. Circular full-thickness skin defect wounds (15 mm in diameter) were created on the backs of the rats in the three groups. The wounds were then treated with 100 μl Lp-PRP, Lr-PRP and saline, respectively. At 7 and 14 days post-operation, the wounds were photographed, and Image J software was used to calculate the wound area rate (postoperative wound area/wound area at modeling time × 100%). At 14 days post-operation, the total neo-epithelium length and collagen deposition rate of the wounds were evaluated using HE and Masson staining, respectively. At 7 days post-operation, the relative expression of vascular endothelial growth factor (VEGF) in the wounds was detected by Western blotting, and the number of CD31 positive microvessels in the wounds was examined by immunohistochemistry. Statistical analysis was performed using SPSS 28.0. One-way analysis of variance (ANOVA) was used to compare the three groups, and Tukey’s test was used for pairwise comparisons. A significance level of P<0.05 was considered statistically significant. Results:Blood analysis revealed that the platelet concentrations in the prepared Lp-PRP and Lr-PRP were 4.1 times and 4.5 times that of whole blood, respectively ( P<0.01), with no significant difference between the two PRPs ( P>0.05). The leukocyte concentration in Lp-PRP was undetectable, while in Lr-PRP, it was 3.5 times that of whole blood ( P<0.01). The wound area rate at 7 and 14 days post-operation, the total neo-epithelium length and collagen deposition rate at 14 days post-operation, as well as the relative expression of VEGF and the number of CD31-positive microvessels at 7 days post-operation in the Lp-PRP and Lr-PRP groups were superior to those in the control group (all P<0.01). However, there was no significant difference between the two PRP groups (all P>0.05). Conclusion:Both Lp-PRP and Lr-PRP promote dorsal wound healing in rats by enhancing re-epithelialization, collagen deposition, and angiogenesis. The impacts of Lp-PRP and Lr-PRP on promoting wound healing are comparable and not influenced by the presence of leukocytes in PRPs.

Objective:To identify the independent factors of unplanned interruption during continuous renal replacement therapy (CRRT) and construct a risk prediction model, and to verify the clinical application effectiveness of the model.Methods:A retrospective study was conducted on critically ill adult patients who received CRRT treatment in the intensive care unit (ICU) of Zhejiang Hospital from January 2021 to August 2022 for model construction. According to whether unplanned weaning occurred, the patients were divided into two groups. The potential influencing factors of unplanned CRRT weaning in the two groups were compared. The independent influencing factors of unplanned CRRT weaning were screened by binary Logistic regression and a risk prediction model was constructed. The goodness of fit of the model was verified by a Hosmer-Lemeshow test and its predictive validity was evaluated by receiver operator characteristic curve (ROC curve). Then embed the risk prediction model into the hospital's ICU multifunctional electronic medical record system for severe illness, critically ill patients with CRRT admitted to the ICU of Zhejiang Hospital from November 2022 to October 2023 were prospectively analyzed to verify the model's clinical application effect.Results:① Model construction and internal validation: a total of 331 critically ill patients with CRRT were included to be retrospectively analyzed. Among them, there were 238 patients in planned interruption group and 93 patients in unplanned interruption group. Compared with the planned interruption group, the unplanned interruption group was shown as a lower proportion of males (80.6% vs. 91.6%) and a higher proportion of chronic diseases (60.2% vs. 41.6%), poor blood purification catheter function (31.2% vs. 6.3%), as a higher platelet count (PLT) before CRRT initiation [×10 9/L: 137 (101, 187) vs. 109 (74, 160)], lower level of blood flow rate [mL/min: 120 (120, 150) vs. 150 (140, 180)], higher proportion of using pre-dilution (37.6% vs. 23.5%), higher filtration fraction [23.0% (17.5%, 32.9%) vs. 19.1% (15.7%, 22.6%)], and frequency of blood pump stops [times: 19 (14, 21) vs. 9 (6, 13)], the differences of the above 8 factors between the two groups were statistically significant (all P < 0.05). Binary Logistic regression analysis showed that chronic diseases [odds ratio ( OR) = 3.063, 95% confidence interval (95% CI) was 1.200-7.819], blood purification catheter function ( OR = 4.429, 95% CI was 1.270-15.451), blood flow rate ( OR = 0.928, 95% CI was 0.900-0.957), and frequency of blood pump stops ( OR = 1.339, 95% CI was 1.231-1.457) were the independent factors for the unplanned interruption of CRRT (all P < 0.05). These 4 factors were used to construct a risk prediction model, and ROC curve analysis showed that the area under the curve (AUC) predicted by the model was 0.952 (95% CI was 0.930-0.973, P = 0.003 0), with a sensitivity of 88.2%, a specificity of 89.9%, and a maximum value of 1.781 for the Youden index. ② External validation: prospective inclusion of 110 patients, including 63 planned interruption group and 47 unplanned interruption group. ROC curve analysis showed that the AUC of the risk prediction model was 0.919 (95% CI was 0.870-0.969, P = 0.004 3), with a sensitivity of 91.5%, a specificity of 79.4%, and a maximum value of the Youden index of 1.709. Conclusion:The risk prediction model for unplanned interruption during CRRT has a high predictive efficiency, allowing for rapid and real-time identification of the high risk patients, thus providing references for preventative nursing.
