Patients with acute heart failure (AHF) often experience dyspnea, and monitoring and quantifying their breathing patterns can provide reference information for disease and prognosis assessment. In this study, 39 AHF patients and 24 healthy subjects were included. Nighttime chest-abdominal respiratory signals were collected using wearable devices, and the differences in nocturnal breathing patterns between the two groups were quantitatively analyzed. Compared with the healthy group, the AHF group showed a higher mean breathing rate (BR_mean) [(21.03 ± 3.84) beat/min vs. (15.95 ± 3.08) beat/min, P < 0.001], and larger R_RSBI_cv [70.96% (54.34%–104.28)% vs. 58.48% (45.34%–65.95)%, P = 0.005], greater AB_ratio_cv [(22.52 ± 7.14)% vs. (17.10 ± 6.83)%, P = 0.004], and smaller SampEn (0.67 ± 0.37 vs. 1.01 ± 0.29, P < 0.001). Additionally, the mean inspiratory time (TI_mean) and expiration time (TE_mean) were shorter, TI_cv and TE_cv were greater. Furthermore, the LBI_cv was greater, while SD1 and SD2 on the Poincare plot were larger in the AHF group, all of which showed statistically significant differences. Logistic regression calibration revealed that the TI_mean reduction was a risk factor for AHF. The BR_ mean demonstrated the strongest ability to distinguish between the two groups, with an area under the curve (AUC) of 0.846. Parameters such as breathing period, amplitude, coordination, and nonlinear parameters effectively quantify abnormal breathing patterns in AHF patients. Specifically, the reduction in TI_mean serves as a risk factor for AHF, while the BR_mean distinguishes between the two groups. These findings have the potential to provide new information for the assessment of AHF patients.
As one of the first batch of pilot universities for the education reform of clinical medicine master program, Sichuan university has conducted in-depth research on the training models in medical schools from home and abroad since 2013. Relying on the platform of medical education collaboration, we have explored and gradually formed the “five early” education model for clinical medicine master program. This article summarizes the practical experience of “five early” education model from six dimensions, namely, PDCA management system, rules and regulations, platform support, database construction, case database construction and international exchange. In addition,, the achievements in the training of medical talents with comprehensive qualities are presented from the aspects of clinical skills, scientific research achievements, international exchanges and frontier innovation, The goal is to provide effective experience for clinical medical personnel training.
ObjectiveTo investigate the efficacy of Orem's self-care model in school-age children with asthma. MethodsSeventy-four children with asthma treated between March 2012 and June 2014 were divided into observation group (n=37) and control group (n=37) randomly. Orem's self-care model was applied in the observation group, while routine nursing was carried out in the control group. We observed the pulmonary function, therapeutic compliance and quality of life in children of both the two groups before and one year after treatment. ResultsOne year after treatment, forced expiratory volume in one second and peak expiratory flow increased significantly (P<0.05), and increase in the observation group was significantly more than that in the control group (P<0.05). Compared with the control group, the observation group showed significant increased treatment compliance rate (P<0.05). Pediatric asthma quality of life questionare scale results showed that one year after treatment, the two groups got significantly increased scores in the dimensions of emotion, symptom and activity (P<0.05), and the scores were significantly higher in the observation group (P<0.05). ConclusionOrem's self-care model has a significant curative effect for the improvement of lung function in school-age children with asthma, which can promot the treatment compliance and quality of life of the patients.
Objective To summarize recent advances on preoperative staging strategies in rectal cancer. Methods Relevant references about preoperative staging strategies were collected and reviewed. The multimodal preoperative evaluation (MPE) system recently documented was focused on. Results The comparably accurate T and M stage could be achieved preoperatively by following an appropriate available method; however, the N stage’s accuracy was still not satisfying. The MPE system， incorporating with the advantages of transrectal ultrasound， computerized tomography and serum amyloid A protein in a multi-disciplinary mode could display the most accurate preoperative staging for rectal cancer currently. Conclusion The MPE has potential prospects in preoperative staging of rectal cancer， and can provide the most accurate preoperative staging for rectal cancer at present.
Objective To analyze the influencing factors of single-center day surgery patients who are discharged from the hospital on the same-day, in order to provide reference and basis for the clinical practice of follow-up day surgery. Methods The electronic medical records of patients who underwent day surgery in the Day Surgery Center of the First Affiliated Hospital of the Air Force Military Medical University between February and October 2021 were analyzed retrospectively. The patients were divided into the same-day discharge group and non-same-day discharge group. The baseline data and perioperative indicators of the patients were analyzed. Results A total of 857 patients were included, including 264 patients (30.81%) in the same-day discharge group and 593 patients (69.19%) in the non-same-day discharge group. Univariate analysis showed that there were significant differences between the two groups in gender, age, body mass index, whether the first one, disease classification, anesthesia method, and intraoperative blood loss (P<0.05). Logistic regression analysis showed that gender, whether the first one, disease classification, surgical grade, anesthesia method, and intraoperative blood loss were independent factors affecting the delayed discharge of patients undergoing daytime surgery (P<0.05). Conclusions There are many factors that affect day surgery patients’ discharge. It is suggested that more rigorously screen patients for day surgery, improve medical technology, strengthen out-of-hospital continued care, and optimize management procedures, so as to shorten the time of patients in hospital and provide more information for patients, and provide more efficient and convenient medical services for patients.

Due to the high complexity and subject variability of motor imagery electroencephalogram, its decoding is limited by the inadequate accuracy of traditional recognition models. To resolve this problem, a recognition model for motor imagery electroencephalogram based on flicker noise spectrum (FNS) and weighted filter bank common spatial pattern (wFBCSP) was proposed. First, the FNS method was used to analyze the motor imagery electroencephalogram. Using the second derivative moment as structure function, the ensued precursor time series were generated by using a sliding window strategy, so that hidden dynamic information of transition phase could be captured. Then, based on the characteristic of signal frequency band, the feature of the transition phase precursor time series and reaction phase series were extracted by wFBCSP, generating features representing relevant transition and reaction phase. To make the selected features adapt to subject variability and realize better generalization, algorithm of minimum redundancy maximum relevance was further used to select features. Finally, support vector machine as the classifier was used for the classification. In the motor imagery electroencephalogram recognition, the method proposed in this study yielded an average accuracy of 86.34%, which is higher than the comparison methods. Thus, our proposed method provides a new idea for decoding motor imagery electroencephalogram.
