Objective:To explore the effects of hospital-to-community model-based case management on outcomes and life quality of patients with atrial fibrillation.Methods:By convience sampling method, a total of 90 cases of atrial fibrillation patients admitted to Changzhou Second People′s Hospital from January 2019 to May 2020 were randomly divided into control group and experimental group, with 45 cases in each group. The patients in the control group received routine nursing care, the experimental group implemented hospital-to-community model-based case management. The beliefs about medicine, medication compliance, quality of life and readmissions of cardiovascular events were compared between 2 groups before and 6 months after intervention.Results:Finally, 41 cases were included in the experimental group and 38 cases in the control group. Before intervention, there were no significant differences in various indexes between the two groups ( P>0.05). After 6 months of intervention, the scores of specific-necessity in Beliefs about Medicines Questionnaire-Specific (BMQ-Specific) and Morisky Medication Adherence Scale-8 (MMAS-8) were (16.98 ± 4.22) and (7.15 ± 0.69) points in the experimental group, higher than in the control group (14.95 ± 4.33) and (6.32 ± 1.07) points; the scores of specific-concerns in BMQ-Specific were (6.83 ± 1.91)points in the experimental group, lower than in the control group (8.42 ± 2.73) points. The differences were statistically significant ( t = 2.11, 4.07, 2.98, all P<0.05); the scores of physical function, role-physical, pain, general health, mental health dimensions and total scores in SF-36 were (80.37 ± 3.46), (46.63 ± 14.54), (90.37 ± 5.78), (70.07 ± 9.98), (84.20 ± 8.73) and (584.88 ± 25.71) points in the experimental group, higher than in the control group (70.13 ± 11.20), (37.34 ± 10.25), (83.37 ± 6.89), (59.55 ± 7.98), (77.58 ± 9.09) and (533.87 ± 31.62) points, the differences were statistically significant ( t values were 3.30-7.89, all P<0.05). At 6 months after discharge, the re-admission of cardiovascular events were 5 cases (12.2%) in the experimental group and 12 cases (31.6%) in the control group, the difference was statistically significant ( χ2=4.74, P<0.05). Conclusions:Hospital-to-community model-based case management can effectively promote beliefs about medicine and medication compliance, improve quality of life and decrease re-admission of cardiovascular events of patients with atrial fibrillation.

The automatic recognition technology of muscle fatigue has widespread application in the field of kinesiology and rehabilitation medicine. In this paper, we used surface electromyography (sEMG) to study the recognition of leg muscle fatigue during circuit resistance training. The purpose of this study was to solve the problem that the sEMG signals have a lot of noise interference and the recognition accuracy of the existing muscle fatigue recognition model is not high enough. First, we proposed an improved wavelet threshold function denoising algorithm to denoise the sEMG signal. Then, we build a muscle fatigue state recognition model based on long short-term memory (LSTM), and used the Holdout method to evaluate the performance of the model. Finally, the denoising effect of the improved wavelet threshold function denoising method proposed in this paper was compared with the denoising effect of the traditional wavelet threshold denoising method. We compared the performance of the proposed muscle fatigue recognition model with that of particle swarm optimization support vector machine (PSO-SVM) and convolutional neural network (CNN). The results showed that the new wavelet threshold function had better denoising performance than hard and soft threshold functions. The accuracy of LSTM network model in identifying muscle fatigue was 4.89% and 2.47% higher than that of PSO-SVM and CNN, respectively. The sEMG signal denoising method and muscle fatigue recognition model proposed in this paper have important implications for monitoring muscle fatigue during rehabilitation training and exercise.

Recently, evidences show that cancer stem cells (CSCs) are a type of cancer cell group with self-renewal and play a huge role in tumor recurrence, metastasis, and drug resistance. Finding new treatment directions and targets for cancer prognosis and reducing mortality has become a top priority. OCT4, as a transcription factor, participates in maintaining the stem characteristics of CSCs, but the mechanism of OCT4 is often overlooked. In this review, we try to illustrate the mechanism by which OCT4 plays a role in CSCs from the perspective of genetic modification of OCT4, non-coding RNA, complexes and signaling pathways associated with OCT4. Our ultimate goal is to provide new targets for cancer treatment to prolong the survival of cancer patients.

Objective@#To investigate the effect of 1q21 amplification (1q) on the therapeutic response and prognosis of bortezomib(Btz) in the treatment of newly diagnosed multiple myeloma (MM) patients.@*Methods@#A total of 180 newly diagnosed MM were included for analyses of clinical characteristics, cytogenetics, objective response rate (ORR), progression-free survival (PFS) and overall survival (OS), retrospectively. Gene expression profiling (GEP) was analyzed using publicly available R2 platform.@*Results@#① In 180 patients, 1q was found in 51.1% cases. Of them, 174 patients had complete follow-up data, including 88 cases with 1q and 86 without 1q (non-1q). ②Incidence of 1q was positively associated with percentage of IGH rearrangement (72.2%, P=0.017) and 1p deletion (1p) (27.8%, P=0.040). ③ The median PFS was 15.0 and 20.3 months for the 1q group and non-1q group, and the median OS was 29.4 and 44.0 months, respectively. Both PFS and OS of 1q group was significantly shorter than those of the non-1q group (P=0.029 and 0.038, respectively). Multivariate analysis further revealed that 1q was an independent prognostic factor for both PFS (HR=1.910, 95% CI 1.105-3.303, P=0.020) and OS (HR=2.353, 95% CI 1.090-5.078, P=0.029). ④ In 91 evaluable cases with 1q, very good partial remission (VGPR) rate was higher after treatment with Btz than those without Btz (62.1% vs 40.0%, P=0.032). Of note, the patients with 1q who received auto-HSCT after induction with Btz had significantly longer PFS than those without auto-HSCT (19 months vs 13 months, P=0.048). ⑤GEP analysis revealed that 1q21 amplification predominantly up-regulated expression of >50% genes within 1q21 region, and also altered expression of 28% genes in chromosome 1 and 10% genes in whole genome, particularly related to DNA repair and cell cycle.@*Conclusions@#1q is an independent adverse prognostic factor in patients with newly diagnosed MM. It is often associated with 1p deletion and IGH rearrangement. Patients with 1q respond well to Btz-based regimen, but they fail to gain long-term benefit from this treatment itself. However, auto-HSCT following Btz induction might improve survival of patients with 1q, suggesting a potential strategy to treat this high-risk subset of MM. GEP analysis warrants further attention in understanding the mechanisms underlying the high-risk of 1q.

Objective To explore the clinical effents of bevacizumab on the recrudescence of the limbal corneal epithelial cell auto-graft transplantation in treating patients with pterygium.Methods The clinical data of 75 cases(99 eyes) with pterygium were retraspectively reviewed,and they were divided into 3 groups by different conservative treatment.A group:the limbal corneal epithelial cell auto-graft transplantation combined with bevacizumab.B group:the limbal corneal epithelial cell auto-graft transplantation combined with MMC.C group:the limbal corneal epithelial cell auto-graft transplantation.After follow-up for 3 months,the curative effect and recurrence were compared between the two groups.Results The recurrence of three groups was significantly different( x2 =12.267,P < 0.05 ).The reccurrence rate of A,B,C group were 12.1%,15.2%,45.5%.The recurrence rate of A group and B group wasn't significantly different(x2 =2.117,P >0.05).The recurrence rate of B group and C group wasn't statistically different( x2 --3.930,P < 0.05 ).The recurrence rate of A group and C group was significantly different( x2 =4.155,P < 0.05 ).After 1 week,all patients had different degrees of eye pain,photophobia or tearing,and disappeared after 1 week;2 patients in group B found that limbal shallow scleral necrosis,superficial punctate keratitis.The average time of removal of stitches in group A was 5.9d,group B was 7.0d and group C was 7.5d.Conclusion Bevacizumab could obviously reduce the recrudescence of the limbal corneal epithelial cell auto-graft transplantation in treating patients with pterygium.It was safe with less complications and good prognosis.It was worthy for being widely used in treatment of pterygium.
