@#Currently, in precision cardiac surgery, there are still some pressing issues that need to be addressed. For example, cardiopulmonary bypass remains a critical factor in precise surgical treatment, and many core aspects still rely on the experience and subjective judgment of cardiopulmonary bypass specialists and surgeons, lacking precise data feedback. With the increasing elderly population and rising surgical complexity, precise feedback during cardiopulmonary bypass becomes crucial for improving surgical success rates and facilitating high-complexity procedures. Overcoming these key challenges requires not only a solid medical background but also close collaboration among multiple interdisciplinary fields. Establishing a multidisciplinary team encompassing professionals from the medical, information, software, and related industries can provide high-quality solutions to these challenges. This article shows several patents from a collaborative medical and electronic information team, illustrating how to identify unresolved technical issues and find corresponding solutions in the field of precision cardiac surgery while sharing experiences in applying for invention patents.

@#Objective To recognize the different phases of Korotkoff sounds through deep learning technology, so as to improve the accuracy of blood pressure measurement in different populations. Methods A classification model of the Korotkoff sounds phases was designed, which fused attention mechanism (Attention), residual network (ResNet) and bidirectional long short-term memory (BiLSTM). First, a single Korotkoff sound signal was extracted from the whole Korotkoff sounds signals beat by beat, and each Korotkoff sound signal was converted into a Mel spectrogram. Then, the local feature extraction of Mel spectrogram was processed by using the Attention mechanism and ResNet network, and BiLSTM network was used to deal with the temporal relations between features, and full-connection layer network was applied in reducing the dimension of features. Finally, the classification was completed by SoftMax function. The dataset used in this study was collected from 44 volunteers (24 females, 20 males with an average age of 36 years), and the model performance was verified using 10-fold cross-validation. Results The classification accuracy of the established model for the 5 types of Korotkoff sounds phases was 93.4%, which was higher than that of other models. Conclusion This study proves that the deep learning method can accurately classify Korotkoff sounds phases, which lays a strong technical foundation for the subsequent design of automatic blood pressure measurement methods based on the classification of the Korotkoff sounds phases.

Objective Using Cerenkov radiation energy transfer (CRET) effect of rare earth nanoparticles (RENPs) to enhance and convert Cerenkov luminescence into Cerenkov luminescence excited fluorescence,and to compare the accuracy of Cerenkov luminescence tomography (CLT) and Cerenkov luminescence excited fluorescence tomography (CLFT).Methods 68Ga (0.74 MBq) was used to respectively excite Y2O3 ∶Eu3+,Er2O3 and Eu2O3(10 mg/ml).Various radioactivities of 68Ga (3.70,1.85,0.92,0.46,0.23 MBq) were used to respectively excite Y2O3 ∶Eu3+ with a fixed concentration (10 mg/ml).A fixed radioactivity of 68Ga (3.70 MBq) was used to excite Y2O3 ∶Eu3+ with different concentrations (10.0,5.0,2.5,1.2,0.6 mg/ml) in order to find the relationships between the optical intensity and the radioactivity of 68Ga or the concentration of Y2O3 ∶Eu3+.Polyethylene tubes containing 68Ga (0.74 MBq) and 68Ga (0.74 MBq) +Y2O3 ∶Eu3+(1 mg) were respectively implanted into two nude mice,then PET/CT and optical imaging were acquired.Three-dimensional reconstruction was proceeded.One-way analysis of variance,two-sample t test,linear correlation analysis were used for data analysis.Results Y2O3 ∶Eu3+ could significantly and stably enhance the Cerenkov optical signal (F=53.35,q =17.03,P<0.001).The enhanced optical signal intensity had linear relationships with the radioactivity of 68Ga or the concentration of Y2O3 ∶Eu3+(r values:0.99and 0.93).Three-dimensional reconstruction result showed that CLFT had significantly higher similarity than CLT (0.43±0.14 vs 0.16±0.06,t =5.090,P<0.05).Conclusion CLFT could reflect the distribution of radiopharmaceuticals more precisely than CLT,and therefore might have potential in biologic optical imaging.
RESUMEN
Objective To quantitatively compare the diagnostic capability of 68Ga-NGR and 18F-FDG in well-differentiated hepatocellular carcinoma (HCC) bearing mice by microPET/CT imaging.Methods The in vitro cellular uptake, in vivo microPET/CT imaging and biodistribution studies of 68Ga-NGR and 18F-FDG were quantitatively compared in SMMC-7721-based well-differentiated HCC.The human fibrosarcoma (HT-1080) and human colorectal adenocarcinoma (HT-29) cells/xenografts were respectively used as positive and negative reference groups for CD13.The expression of CD13 was qualitatively verified by immunohistostaining.The levels of CD13 and glucose-6-phosphatase (G6Pase) were semi-quantitatively analyzed by Western blot test for all 3 types of tumors.Two-sample t test was used for data analysis.Results The in vitro cellular uptake showed that the 68Ga-NGR uptake in SMMC-7721 and HT-1080 cells was higher than that in HT-29 cells, and the 68Ga-NGR uptake was higher than 18F-FDG uptake in SMMC-7721 cells.The in vivo microPET/CT imaging results revealed that the uptake of 68Ga-NGR in SMMC-7721 tumor was (2.17±0.21) %ID/g, remarkably higher compared to (0.73±0.26) %ID/g of 18F-FDG uptake (t=8.826, P<0.01).The tumor/liver ratio of 68Ga-NGR was 2.05±0.16, which was 2.03-fold higher than that of 18F-FDG.In the HT-1080 tumors, the uptakes of 68Ga-NGR and 18F-FDG were both high, and the values were (2.46±0.23) %ID/g, (3.47±0.31) %ID/g.The uptake of 68Ga-NGR was significantly lower than that of 18F-FDG in HT-29 tumors: (0.67±0.20) %ID/g vs (3.17±0.29) %ID/g;t=4.221, P<0.01.Western blot and immunohistostaining results were as follows: HT-1080(CD13+, G6Pase-), SMMC-7721(CD13+, G6Pase+), HT-29(CD13-, G6Pase-).Conclusions The uptake of 68Ga-NGR is higher than 18F-FDG uptake in SMMC-7721 tumor bearing mice, therefore it is worthwhile to consider the feasibility of clinical translation for PET/CT in diagnosis of HCC.Furthermore, because of the difference in 68Ga-NGR and 18F-FDG avidities in tumors with different molecular phenotypes of CD13 and G6Pase, there is an underlying potential for molecular imaging in the determination of molecular phenotypes.
