Objective:To explore application value of dance movement therapy in the chemotherapy of young and middle-aged patients with breast cancer, so as to provide reference for rehabilitation nursing.Methods:By convenient sampling method, 90 young and middle-aged female breast cancer patients during chemotherapy from June 2020 to June 2021 in Renmin Hospital of Wuhan University were enrolled in the present study. They were assiged to experimental group and control group with 45 cases in each group according to the enrolled ward. The control group received routine nursing and the experimental group received 4 cycles of dance movement therapy. Before and after intervention, the effects were assessed by Cancer Fatigue Scale (CFS) and Patient-Generated Subjective Global Assessment (PG-SGA) as well as biochemical nutrition indexes.Results:After intervention, the physical fatigue score, emotional fatigue score, cognitive fatigue score and total CFS score were (8.29 ± 3.58), (7.74 ± 1.68), (5.57 ± 1.11), (21.59 ± 4.41) points in the experimental group, which were significantly lower than (9.86 ± 3.49), (8.95 ± 2.62), (6.27 ± 1.70), (25.09 ± 4.33) points in the control group ( t values were 2.07-3.71, all P<0.05). After intervention, the PG-SGA score was (2.81 ± 0.71) points in the experimental group, which was significantly lower than (3.29 ± 1.15) points in the control group ( t=2.37, P<0.05). Conclusions:Dance movement therapy can alleviate the cancer related fatigue and promote nutritional status of young and middle-aged female breast cancer patients with chemotherapy.

Objective:To investigate the difference in left ventricular dysfunction between type 2 diabetes mellitus (T2DM) patients with hyperlipidemia and those without hyperlipidemia, and analyze the application value of three-dimensional speckle tracking technology.Methods:The clinical data of 70 patients with T2DM admitted to Heji Hospital Affiliated to Changzhi Medical College from January 2020 to June 2021 were retrospectively analyzed. Among these patients, 35 patients had hyperlipidemia and 35 patients had no hyperlipidemia. At the same time, 40 healthy subjects who concurrently underwent health checkups in the same hospital were included as healthy controls. All subjects underwent routine cardiac ultrasound and 3D-STE examinations. General clinical information and left ventricular function-related parameters, including global longitudinal strain, global circumferential strain, global area strain, and global radial strain were compared between healthy controls and T2DM patients with hyperlipidemia and those without hyperlipidemia.Results:The proportion of left ventricular remodeling increased in T2DM patients without hyperlipidemia, and the proportion of left ventricular hypertrophy was the highest in T2DM patients with hyperlipidemia. Global longitudinal strain and global circumferential strain in T2DM patients without hyperlipidemia were (-16.97 ± 2.59)% and (-17.41 ± 2.50)%, respectively, which were significantly higher than (-18.86 ± 2.46)% and (-18.71 ± 2.92)% in healthy controls ( t = 0.95, 0.57, both P < 0.05). Global longitudinal strain, global circumferential strain, and global area strain in T2DM patients with hyperlipidemia were (-14.98 ± 3.15)%, (-15.80 ± 3.16)%, (-27.17 ± 4.54)%, respectively, which were significantly higher than (-18.86 ± 2.46)%, (-18.71 ± 2.92)%, (-30.62 ± 4.02)% in healthy controls ( t = 0.46, 1.37, 0.98, all P < 0.05) and (-16.97 ± 2.59)%, (-17.41 ± 2.50)%, (-30.06 ± 3.59)% in T2DM patients without hyperlipidemia ( t = 0.37, 1.02, 0.77, all P < 0.05). Global radial strain in T2DM patients with hyperlipidemia was significantly higher than [(51.49 ± 8.94)%, t = 1.35, P < 0.05] in healthy controls and [(47.71± 8.46)%, t = 0.98, P < 0.05] in T2DM patients without hyperlipidemia. In patients with T2DM, fasting blood glucose and hyperlipidemia were independently correlated with all strain-related parameters. Conclusion:Hyperlipidemia can aggravate left ventricular remodeling and dysfunction in patients with T2DM and 3D-STE is one of the examination methods for subclinical left ventricular remodeling and dysfunction in T2DM patients with or without hyperlipidemia.

BACKGROUND:For the replacement treatment of long-segment tracheal defects,although tissue engineering research has made some progress in recent years,it is still not perfect,and one of the biggest difficulties is that the hemodynamic reconstruction of the tracheal replacement cannot be achieved rapidly. OBJECTIVE:To preliminarily explore the potential of polycaprolactone scaffolds modified with exosome-loaded hydrogels to construct a rapidly vascularized tracheal substitute. METHODS:Exosomes were extracted from bone marrow mesenchymal stem cells of SD rats.After preparation of hyaluronic acid methacrylate solution,the exosome solution was mixed with hyaluronic acid methacrylate solution at a volume ratio of 1:1.Hyaluronic acid methacrylate hydrogels loaded with exosomes were prepared under ultraviolet irradiation for 5 minutes.The degradation of exosome-unloaded hydrogels and the controlled release of exosome-loaded hydrogels were detected.Polycaprolactone scaffolds were prepared by 3D printing.The pure hyaluronic acid methacrylate solution and the exosome-loaded hyaluronic acid methacrylate solution were respectively added to the surface of the scaffold.Hydrogel-modified scaffolds and exosome-modified scaffolds were obtained after ultraviolet irradiation.Thirty SD rats were randomly divided into three groups with 10 rats in each group and subcutaneously implanted with simple scaffolds,hydrogel-modified scaffolds and exosome-modified scaffolds,respectively.At 30 days after surgery,the scaffolds and surrounding tissues of each group were removed.Neovascularization was observed by hematoxylin-eosin staining and Masson staining and the expression of CD31 was detected by immunofluorescence. RESULTS AND CONCLUSION:(1)As time went by,the hydrogel degraded gradually,and the exosomes enclosed in the hydrogel were gradually released,which could be sustained for more than 30 days.The exosome release rate was faster than the degradation rate of the hydrogel itself,and nearly 20%of the exosomes were still not released after 30 days of soaking.(2)Under a scanning electron microscope,the surface of the simple polycaprolactone scaffold was rough.After hydrogel modification,a layer of gel was covered between the pores of the scaffold,and the scaffold surface became smooth and dense.(3)After 30 days of subcutaneous embedding,hematoxylin-eosin staining and Masson staining showed that more neovascularization was observed inside the scaffolds of the exosome-modified scaffold group compared with the hydrogel-modified scaffold group.The hydrogels on the scaffolds of the two groups were not completely degraded.Immunofluorescence staining showed that CD31 expression in the exosome-modified scaffold group was higher than that in the hydrogel-modified scaffold group(P<0.000 1).(4)These results indicate that hyaluronic acid methacrylate hydrogels can be used as controlled-release carriers for exosomes.The 3D-printed polycaprolactone scaffold modified by hyaluronic acid methacrylate hydrogel loaded with exosomes has good biocompatibility and has the potential to promote the formation of neovascularization.

Objective To explore the feasibility of the deep convolutional neural network (DCNN) judging the indications and prognosis of the total knee arthroplasty based on the trained DCNN computer learning system.Methods C1FAR-10 DCNN model based on TensorFlow (an open source system,Google,USA) optimized by Alex Krizhevsky were constructed.There were 400 cases with knee osteoarthritis from different databases used for analysis.Three hundred patients underwent total knee arthroplasty,while 100 did not.X-ray of 200 preoperative cases from the 400 cases and their enlarged image (50 times) were applied for training DCNN,while the enlarged images from other 200 cases were used to test the DCNN.The correlation and the regression between judgment of the DCNN and clinical truth were analyzed.The clinical truths were rechecked three times and were confirmed by treatment results.Pearson correlation and linear regression analysis were used.The relation test of the software was only used as a reference.Results There was no significant difference between the baseline of cases for learning and test.After learning 200 cases,the DCNN judged the 10 000 cases enlarged from remaining 200 cases.The correlation between the DCNN judgment and the clinical truth was not significant (r=0.000,F=0.001,P=0.970).False positive was observed in 1 681 cases,false negative in 3 296.After enlarged to 10 000 images,the correlation between the two judgments was significant (F=11 228.735,P=0.000,r=0.727 and R2=0.529).The software detection precision was 0.860.Conclusion DCNN can be applied in judging the indications of the total knee arthroplasty.Large sample size can improve the accuracy of the judgment significantly.
