Objective To develop and validate a prediction model for extended hospitalisation in patients with ischemic stroke.Methods A total of 318 patients with ischemic stroke hospitalised between November 2021 and May 2023 in a Grade ⅢA hospital in Changzhou were selected as study objects with a convenience sampling method.The modelling group consisted 212 patients and the validation group included 106 patients.The patients in the modelling group were divided into a group of extended hospital stay and a group of normal hospital stay.Binary logistic regression analysis was conducted to develop the prediction model,and data from the 106 patients in the validation group were then incorporated into the developed prediction model.The prediction performance and goodness-of-fit of the model were accessed using the area under the curve(AUC)of the receiver operation characteristic(ROC)curve and the Hosmer-Lemeshow test.Results Multivariate logistic analysis showed that comorbid diabetes,number of complications during hospitalisation,a Braden score less than 18,and a white blood cell count greater than 3.5×109/L or more than 9.5×109/L were the risk factors of extended hospitalisation in patients with cerebral ischemic stroke.Based on the factors,a prediction model was developed with following formula:P=1/[1+exp(-Z)].Hosmer-Lemeshow test for the prediction model yielded χ 2=7.430,P=0.191.AUC of the prediction model was 0.818(95％CI:0.754-0.883,P<0.001)with Jordon index of 0.51 and the optimal cut-off value of 0.268,sensitivity of 78.9％and specificity of 72.3％The results of the validation of independent data model showed a sensitivity of 75.0％,specificity of 74.4％,and accuracy of 74.5％.Conclusion Comorbid diabetes,Braden score at admission,white blood cell count and the number of complications during hospitalisation are the significant factors that affect the length of hospital stay in the patients with ischemic stroke.The prediction model for extended hospitalisation of the patients with ischemic stroke exhibits good predictive value and can provide reference in clinical decision-making.

Chronic myeloid leukemia(CML)is a hematological system malignant tumor characterized by the appearance of Ph chromosomes and the formation of BCR-ABL fusion gene.With the emergence of tyrosine kinase inhibitors,the efficacy and survival of CML have been improved significantly.However,there are still some patients with inevitable disease progression and recurrence.In CML patients,the body's own an-ti-tumor immunity can play a role in monitoring,recognizing and eliminating the leukemia cells,which is closely correlated with the occurrence,development,curative efficacy and prognosis of the disease.The immune cells such as natural killer(NK)cells,T cells,dendritic cells,Treg and MDSC play a key role in anti-tumor immunity.Therefore,this article reviews the characteristics of CML immune cells,correlation between the body's own anti-tumor immune status and therapeutic effect,and the recent progress of CML immunotherapy.

OBJECTIVE To predict the amount of colorants used in the preparation of placebo of Chinese medicine by construc-ting particle swarm optimization-back propagation neural network PSO-BPNN compound granules,and to provide a new idea for the simulation of placebo color of Chinese medicine compound granules.METHODS The BP neural network was used to establish the model of sample color parameters L,a?,b?and pigment mass fraction.The global search ability of particle swarm optimization algo-rithm was used to optimize the weight and bias of BP neural network to prevent the local minimum value of the model.The linear reduc-tion weight coefficient method and the introduction of mutation operator were used to improve the global optimization ability of particle swarm optimization algorithm.The color comprehensive evaluation index(ΔE)was used as the objective evaluation standard to verify the test results.RESULTS The training results show that the fitting accuracy of the improved PSO-BP neural network was up to 98.31%.The prediction results show that the prediction error of the improved PSO-BP neural network was the smallest,and the mean absolute percentage error(MAPE),root mean square error(RMSE)and mean color difference(ΔE)were 0.411 5,2.164 6 and 2.56,respectively.The verification samples of three kinds of particles were prepared for verification.The ΔE of the verification sample and the model drug were 1.73,2.63 and 4.11,respectively.The color difference between the two groups and the model drug was small by visual evaluation.CONCLUSION The BP neural network based on the improved particle swarm optimization algorithm can simulate the prediction of the amount of colorants used in the preparation of Chinese medicine compound granules,and can be used as a recommended optimization model for placebo color matching research.

Objective To observe the effect of Qixian Tongluo Formula on contralateral corticospinal tract(CST)remodeling and motor functional recovery in rats with cerebral infarction,and to explore its potential molecular mechanism from the perspective of regulating factors related to never remodeling.Methods The rat middle cerebral artery occlusion(MCAO)model was established by silk thread ligation.Fifty model rats were randomly divided into model group,citicoline group(0.054 g·kg-1),Qixian Tongluo Formula low-,medium-and high-dose(7.83,15.66,31.32 g·kg-1)groups,and sham operation group,with 10 rats in each group.The intervention administration was started on the 3rd day after operation once a day for 26 consecutive days.On the 3rd,14th and 28th day after operation,the gross motor function was evaluated by Longa score,and the fine motor function was evaluated by beam-walking test(BWT)score.The contralateral motor cortex was injected with the nerve tracer biotin dextran amine(BDA)on the 14 th day after operation to anterogradely trace the CST.On the 28th day after operation,the expression of axonal growth associated protein-43(GAP-43)and BDA positive fibers in the contralateral motor cortex and cervical spinal cord were detected by immunohistochemistry.The co-localization areas of BDA positive fibers and presynaptic marker protein vesicular glutamate transporter 1(VGLUT1)in the cervical spinal cord gray matter were detected by immunofluorescence.The expressions of brain-derived neurotrophic factor(BDNF),glial cell-derived neurotrophic factor(GDNF),nerve growth factor(NGF)and nerve remodeling-associated inhibitory factor[Nogo-A,oligodendrocyte myelin glycoprotein(OMgp)and myelin-associated glycoprotein(MAG)]in the contralateral motor cortex were detected by Western Blot.Pearson correlation analysis was used to analyze the correlation between Longa score or BWT score and BDA/VGLUT1 co-localization area,respectively.Results Compared with the sham operation group,rats in the model group had obvious symptoms of motor function deficits,and the Longa scores were significantly increased(P＜0.01)and the BWT scores were significantly decreased(P＜0.05,P＜0.01)at each time point.The expression of GAP-43 in the contralateral motor cortex and cervical spinal cord was up-regulated(P＜0.05),the number of edge-crossing fibers from the posterior funiculus in cervical cord was increased(P＜0.05),the co-localization area of BDA/VGLUT1 in the gray matter of the cervical spinal cord was increased(P＜0.05),the expressions of BDNF,GDNF and NGF in the contralateral motor cortex were up-regulated(P＜0.05),while the expressions of Nogo-A,OMgp and MAG were down-regulated(P＜0.05).Compared with the model group,the Longa scores in each administration group on the 14th and 28th day after MCAO operation were significantly decreased(P＜0.01),the BWT scores were significantly increased(P＜0.01),the expression of GAP-43 in the contralateral motor cortex and cervical spinal cord was significantly up-regulated(P＜0.01).The number of edge-crossing fibers from the posterior funiculus in cervical cord was significantly increased(P＜0.01),the co-localization area of BDA/VGLUT1 in the gray matter of the cervical spinal cord was significantly increased(P＜0.01).The expressions of BDNF,GDNF and NGF in the contralateral motor cortex were significantly up-regulated(P＜0.01,P＜0.05),while the expressions of Nogo-A,OMgp and MAG were significantly down-regulated(P＜0.05),and the most significant effect was observed in the high dose group.The Longa score was negatively correlated with the co-localization area of BDA/VGLUT1(r=-0.89,P＜0.01),and the BWT score was positively correlated with the co-localization area of BDA/VGLUT1(r=0.84,P＜0.01).Conclusion Qixian Tongluo Formula can improve motor function through promoting contralateral CST remodeling in MCAO rats after cerebral infarction,and the molecular mechanism may be related to the regulation of the expression of nerve remodeling-associated factor in the contralateral motor cortex.
