Objective To explore the implementation styles on the therapeutic effects on the neurosurgical intensive care unit (NICU) patients. Methods Patients were enrolled during February 3, 2015 to February 3, 2016. The key point time was August 3, 2015 when the treatment in our NICU was fully implemented by NICU professional doctors. Based on this time point, all the enrolled patients were divided into non-NICU professional doctor implementing (NNPDI) group and NICU professional doctor implementing (NPDI) group. Thus non-NICU professional doctors and professional doctors were the leaders of diagnosis and treatment in tow groups. The length of hospital stay, complications, prognosis and other therapeutic outcomes were compared between two groups. Results The length of hospital stay was longer in NPDI group than that in NNPDI group (P<0.05). The incidence of water-electrolyte imbalance was lower in NPDI group than that in NNPDI group (P<0.05). There were no significant differences in the incidence of the ventilator-associated pneumonia (VAP), the hepatic and renal insufficiency, the intracranial infections and stress ulcers between the two groups (P>0.05). The proportion of referral to other wards and fatality rate were both lower in NPDI group than those in NNPDI group (P<0.05). And the discharge rate from NICU was higher in NPDI group than that of NNPDI group (P<0.05). There was no significant difference in the rate of patients left hospital without treatment between the two groups (P>0.05). Conclusion The NICU professional doctor implementing may be contribute to, at least in part, the improving of prognosis of NICU patients without obvious advantages in most complications. The level of professional management remains to be improved.

Objective:To investigate the effects of curcumin on proliferation, cell cycle, and apoptosis of human thyroid cancer TPC-1 cells.Methods:Logarithmic growth phase TPC-1 cells were treated with 0.0, 7.5, 15.0 and 22.5 μmol/L curcumin for 48 h. Cell proliferation levels were determined using the methylthiazolyl tetrazolium (MTT) assay. Cell cycle and apoptosis levels were measured using flow cytometry. Western blot method was used to determine the expression levels of B cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax).Results:The inhibition rates of cell proliferation in 7.5, 15.0 and 22.5 μmol/L curcumin groups were higher than that of 0.0 μmol/L curcumin group ( P < 0.05); the proportion of G0/G1 phase was higher than that of 0.0 μmol/L curcumin group, but the proportions of G2/M and S phase were lower than those of 0.0 μmol/L curcumin group ( P < 0.05); the cell apoptosis rate was higher than that of 0.0 μmol/L curcumin group [(14.13 ± 0.57)%, (25.27 ± 0.62)%, (36.01 ± 0.84)% vs (8.48 ± 0.43)%, P < 0.05]; the protein expression of Bcl-2 was lower than that of 0.0 μmol/L curcumin group, and protein expression of Bax was higher than that of 0.0 μmol/L curcumin group ( P < 0.05). Conclusion:Curcumin can inhibit the proliferation of TPC-1 cells, block the cell cycle in G0/G1 phase, and promote cell apoptosis by downregulating Bcl-2 expression and upregulating Bax expression.

To address the issues in the current lung nodule detection for tuberculosis where the existing object detection algorithms have limited precision for small nodules and often predict bounding box locations inaccurately,a lung nodule detection method based on YOLOv7 is presented for obtaining small lung nodules more effectively and realizing the continuous convergence of target detection box.Based on the framework of YOLOv7 network model,the improvements are made in the following 3 aspects.(1)The cross-channel information and target airspace information are obtained with the effective SimAM channel attention mechanism embed in the Head network,so as to highlight the target features and enable the model to identify the regions of interest more accurately.(2)SIOU boundary loss function is used to increase the angle cost on the original loss function,and redefine the distance cost and shape cost to improve the convergence rate and reduce the loss value.(3)SIOU-NMS is used to replace the non-maximum suppression algorithm for reducing the error suppression due to target occlusion.The results of experiments on a custom lung nodule dataset show that compared with the original YOLOv7,the proposed method improves accuracy and recall rate by 2.9%and 3.1%,and the mean average precision at a confidence threshold of 0.5 is increased by 3.7%.The model can effectively assist in the diagnosis of lung nodules.

A U-Net incorporating improved Transformer and convolutional channel attention module is designed for biventricular segmentation in MRI image.By replacing the high-level convolution of U-Net with the improved Transformer,the global feature information can be effectively extracted to cope with the challenge of poor segmentation performance due to the complex morphological variation of the right ventricle.The improved Transformer incorporates a fixed window attention for position localization in the self-attention module,and aggregates the output feature map for reducing the feature map size;and the network learning capability is improved by increasing network depth through the adjustment of multilayer perceptron.To solve the problem of unsatisfactory segmentation performance caused by blurred tissue edges,a feature aggregation module is used for the fusion of multi-level underlying features,and a convolutional channel attention module is adopted to rescale the underlying features to achieve adaptive learning of feature weights.In addition,a plug-and-play feature enhancement module is integrated to improve the segmentation performance which is affected by feature loss due to channel decay in the codec structure,which guarantees the spatial information while increasing the proportion of useful channel information.The test on the ACDC dataset shows that the proposed method has higher biventricular segmentation accuracy,especially for the right ventricle segmentation.Compared with other methods,the proposed method improves the DSC coefficient by at least 2.83%,proving its effectiveness in biventricular segmentation.
