Objective To investigate the effect of vacuum-assisted closure(VAC)on the circulating number of endothelia progenitor cell(EPCs)in diabetic patients with mild to moderate degrees of ischemic foot ulcer and their related factors. Methods A total of 84 diabetic patients with foot ulcer duration for at least 4 weeks and ankle brachial index(ABI)0.5~0.9 were selected and divided into and assigned to two groups according to 2: 1 randomization:vacuum-assisted closure(VAC)treatment group(n=56)and Non-VAC treatment group(n=28). The control group (NC) was composed of 18 patients who had normal glucose tolerance and lower extremity ulcer without arteriovenous disease. VAC was performed on the ulcer wound after debridement for 1 week in both VAC group and NC group,and the patients in Non-VAC group received conventional treatment process. The circulating number of EPCs was measured before and after various treatments and the influencing factors of their changes were analyzed. Results After VAC treatment,the circulating number of EPCs significantly increased in both VAC group and NC group[(85.3 ± 18.1)vs(34.1 ± 12.5)/106cells,(119.9 ± 14.4)vs(66.1 ± 10.6)/106cells,both P<0.05]. By contrast,the circulating number of EPCs had no significant change in Non-VAC group[(45.2 ± 19.4)vs(34.7 ± 16.8)/106cells, P>0.05]. In addition,the circulating levels of vascular endothelial growth factor(VEGF)and the protein expressions of VEGF and stromal cell-derived factor-1α(SDF-1α)in the granulation tissue also significantly increased after VAC treatment in both VAC group and NC group,but no significant change in Non-VAC group. Compared with Non-VAC group,the changes of VEGF and SDF-1α levels in the sera and granulation tissue were all significantly higher in both VAC group and NC group(P<0.05 or P<0.01). There were no significant differences in changes of the circulating number of EPCs, and VEGF and SDF-1α in the sera and granulation tissue between VAC group and NC group. Correlation analysis showed that the change of the circulating number of EPCs was correlated with the changes of VEGF and SDF-1α levels in the sera and granulation tissue of VAC group and NC group(P<0.05). Conclusion VAC treatment may increase the circulating number of EPCs in diabetic patients with mild to moderate ischemic foot ulcer as in non-diabetic controls,which may be attributed to the upregulation of systemic and local VEGF and SDF-1α levels.

Objective:To design a lung function prediction method that combines transfer learning and multimodal feature fusion, aiming to improve the accuracy of lung function prediction in patients with idiopathic pulmonary fibrosis (IPF).Methods:CT images and clinical text data were reprocessed, and an adaptive module was designed to find the most suitable lung function attenuation function for IPF patients. The feature extraction module was utilized to comprehensively extract features. The feature extraction module comprises three sub-modules, including CT feature extraction, clinical text feature extraction, and lung function feature extraction. A multimodal feature prediction network was used to comprehensively evaluate the attenuation of lung function. The pre-trained model was fine-tuned to improve the predictive performance of the model.Results:Based on the OSIC pulmonary fibrosis progression competition dataset, it is found through the adaptive module that the linear attenuation hypothesis is more in line with the trend of pulmonary function decline in patients. Different modal data prediction experiments show that the model incorporating clinical text features has better predictive ability than the model using only CT images. The model combining CT images, clinical text features, and lung function features have optimal predictive results. The lung function prediction method combining transfer learning and multimodal feature fusion has modified version of the Laplace log likelihood (LLLm) of ?6.706 5, root mean squared error (RMSE) of 184.5, and mean absolute error (MAE) of 146.2, which outperforms other methods in terms of performance. The pre-trained model has higher prediction accuracy compared to the zero base training model.Conclusions:The lung function prediction method designed by combining transfer learning and multimodal feature fusion can effectively predict the lung function status of IPF patients at different weeks, providing important support for patient health management and disease diagnosis.

ObjectiveTo investigate the effects of Guizhi Jia Longgu Mulitang on the expression difference of interleukin-10 (IL-10) and tumor necrosis factor -α (TNF-α) in related organs of insomnia rats with sensory dysfunction dominated by lung and study the mechanism of Guizhi Jia Longgu Mulitang in improving insomnia. MethodSD rats were randomly divided into the blank group, model group, western medicine group, and traditional Chinese medicine (TCM) group, with 10 rats in each group. The rats were deprived of sleep by shallow water environment method in a long platform, and the modeling lasted for 42 d. The blank group and model group were given 0.05 mL·kg-1 normal saline by gavage, and the western medicine group and TCM group were given drugs during modeling. To be specific, the western medicine group was given 0.105 mg·kg-1 dexzopiclone tablet by gavage, while the TCM group was given 7 600 mg·kg-1 Guizhi Jia Longgu Mulitang by gavage, both lasting for 28 days. After successful modeling, the Morris water maze experiment was performed on the 42nd day to detect the motion and spatial memory ability of rats. The levels of IL-10 and TNF-α in serum were detected by enzyme-linked immunosorbent assay (ELISA). The protein expression of IL-10 and TNF-α in the lung and brain tissue of rats was detected by Western blot. The levels of IL-10 and TNF-α in the lung and brain tissue of rats were detected by immunohistochemistry. ResultCompared with the blank group, the sleep stages non-rapid eye movement ( NREM ) and rapid eye movement ( REM ) of the model group were significantly shortened (P<0.5, P<0.01), and the wake stage was significantly increased (P<0.01). The total time and distance of platform exploration were significantly increased (P<0.01). In the target quadrant (the third quadrant), the percentage of exploration time and the times of crossing the platform were significantly decreased (P<0.01). ELISA results showed that the serum IL-10 level was significantly decreased (P<0.01), and TNF-α level was significantly increased (P<0.01). The results of Western blot showed that the protein expression of IL-10 in brain and lung tissue of rats was significantly decreased (P<0.01), and the protein expression of TNF-α was significantly increased (P<0.01). The results of immunohistochemistry showed that the expression of IL-10 in the brain and lung tissue of rats was significantly decreased (P<0.01), and that of TNF-α was significantly increased (P<0.01). Compared with the model group, the NREM stage and REM stage of the western medicine group and the TCM group were significantly increased (P<0.5, P<0.01), and the wake stage was shortened (P<0.5). The total time and distance of platform exploration were significantly decreased (P<0.01). In the target quadrant (the third quadrant), the percentage of exploration time and the times of crossing the platform were significantly increased (P<0.05, P<0.01). The serum IL-10 level was significantly increased (P<0.01), and the serum TNF-α level was significantly decreased according to the ELISA results (P<0.01). The results of Western blot showed that the protein expression of IL-10 in brain tissue and lung tissue was significantly increased (P<0.01), and the protein expression of TNF-α was significantly decreased (P<0.01). The results of immunohistochemistry showed that the expression of IL-10 in brain tissue and lung tissue was significantly increased (P<0.05, P<0.01), and the expression of TNF-α was significantly decreased (P<0.05, P<0.01). ConclusionGuizhi Jia Longgu Mulitang can improve the expression of IL-10 and TNF-α in brain and lung tissue of insomnia rats with sensory dysfunction dominated by lung, prolong sleep time, and then improve insomnia. The mechanism may be related to improving the expression level of inflammatory factors.
