To evaluate the effectiveness of the perioperative intervention of LAMA/LABA, a randomized prospective trial was performed for the lung cancer patients receiving a lobectomy with normal pulmonary function and COPD. <strong>Methods:</strong> Based on the results of the preoperative pulmonary function test, 25 patients were diagnosed with COPD [% forced expiratory volume in 1 second (%FEV<sub>1</sub>) < 70%]. Thirty-seven patients were enrolled as non-obstructive patients (70% ≤ %FEV<sub>1</sub>), who were randomized into two groups, the LAMA/LABA (n = 19) and the Control group (n = 18). The LAMA/LABA and the COPD groups daily received inhaled LAMA (50 μg) and LABA (110 μg) for 1 week before surgery and for least 4 weeks after surgery. The Control group had no treatment of the dual bronchodilator. The actual values were measured during the perioperative pulmonary function at three points of the preoperative baseline, the postoperative 1 week and the postoperative 4 weeks;these changes and changed ratios were then calculated. The patient-reported outcomes of the quality of life (PRO-QOL) were evaluated by the Cancer Dyspnea Scale (CDS), the COPD assessment test, and the St. George’s Respiratory Questionnaire. <strong>Results:</strong> Regarding the value of FEV<sub>1</sub> at the baseline, that in the LAMA/LABA group was 79.2% ± 6.4% and that in the Control group was 80.9% ± 6.4%, but that in the COPD groups was 57.9% ± 8.7%;there was a significant difference between the COPD and the Control group (p < 0.0001). At the postoperative 1 week point, the FEV<sub>1</sub> value in the Control group was 1.3 ± 0.5 L and that in the LAMA/LABA group was 1.7 ± 0.5 L. On the other hand, that in the COPD group was 1.7 ± 0.5 L, which was significantly higher compared to that in the Control group (p = 0.0251 and p = 0.0369). The intervention of LAMA/LABA for the COPD and non-obstructive patients resulted in the less decreased degree of the pulmonary function in FEV<sub>1</sub> compared to that in the Control group. Based on the PRO-QOL by the CDS, the intervention of LAMA/LABA significantly reduced the total dyspnea in the LAMA/LABA group compared to that in the Control group (p = 0.0348). <strong>Conclusion:</strong> The perioperative intervention of LAMA/LABA should lead to maintaining the postoperative pulmonary function of the FEV<sub>1</sub> during the lobectomy with COPD and non-obstructive patients and the improvement of PRO-QOL.展开更多

We conducted an 18-month randomized controlled tracking study to evaluate the efficacy of social skills training (SST) in 11 individuals with schizophrenia on risperidone monotherapy. They were randomized to either SST or non-SST group, and Global Assessment Functioning (GAF) and Brief Psychiatric Rating Scale (BPRS) scores in the 2 groups showed gradual improvement. In the SST group, Digit Span Distraction Test (DSDT) at 12 and 18 months showed significant improvement. The Subjective Deficit Syndrome Scale (SDSS) scores in the SST group showed significant improvement after 6 months and showed a significant difference in comparison between the groups. After the subjective feeling of health was recovered, the items of motivation were recovered as a direct effect of SST. Some items of the Life Assessment Scale for the Mentally Ill (LASMI) score showed significant improvement (or significant trend) in only the SST group after 6 months. Items of daily life, work skills, and self-recognition were continuously improved. We report 2 cases in the SST group that had DSDT improvement in parallel with change of action and communication as a change of social function. This study is only exploratory due to the small number of cases. However, we have demonstrated potential improvement in cognitive function due to learning experiences that required working memory and attention, thus providing improvement in social life.展开更多

Methods: Randomized controlled trials comparing the use of chewing gum in postoperative recovery with a control group were retrieved from the databases including Pubmed, Cochrane Library, Science Direct, Web of Science, CBM, CNKI, Wanfang and VIP, et al. After screening literatures, evaluating the quality of studies, extracting data, the RevMan5.3 software was used for data analysis. Results: A total of 13 RCTs including 2233 patients were analyzed in the study. The results showed that chewing gum after cesarean delivery can effectively shorten the recovery time of bowel sounds, passage of flatus and first defecation (all P Conclusion: Chewing sugar-free gum after cesarean section can promote the early recovery of gastrointestinal function, but the side effects of chewing gum are still unclear, which needs more clinical, large sample and high-quality studies to further verify.展开更多

The classical frequency-spectrum equalization algorithm needs to compute the average of the multiple frequency response functions （FRFs）, which lengthens the control loop time in the equalization process. Likewise, the feedback control algorithm has a very slow convergence rate due to the small value of the feedback gain parameter to ensure stability of the system. To overcome these limitations, an adaptive inverse control of random vibrations based on the filtered-X least mean-square （LMS） algorithm is proposed. Furthermore, according to the description and iteration characteristics of random vibration tests in the frequency domain, the frequency domain LMS algorithm is adopted to refine the inverse characteristics of the FRF instead of the traditional time domain LMS algorithm. This inverse characteristic, which is called the impedance function of the system under control, is used to update the drive PSD directly. The test results indicated that in addition to successfully avoiding the instability problem that occurs during the iteration process, the adaptive control strategy minimizes the amount of time needed to obtain a short control loop and achieve equalization.展开更多

The communication links between the plant and the controller are assumed to be imperfect （that is, data loss occurs intermittently, which appears typically in a network environment）. The data loss is modelled as a random process which obeys a Bernoulli distribution. In the face of random data loss, a piecewise controller is designed to robustly stabilize the networked system in the sense of mean square and also achieve a prescribed H∞ disturbance attenuation performance based on a piecewise-quadratic Lyapunov function. The required H∞ controllers can be designed by solving a set of linear matrix inequalities （LMIs）.
