Objective To investigate the effect of modified Morita therapy combined with motor imagery training on pulmonary rehabilitation of elderly patients with chronic obstructive pulmonary disease(COPD). Methods Totally 130 elderly COPD patients were selected and divided into two groups according to the random number table method, with 65 cases in each group. During the rehabilitation treatment, the control group received modified Morita therapy intervention, and the observation group received modified Morita therapy combined with motor imagery training. The changes of lung function, negative emotion and quality of life before and after intervention were compared between the two groups. Results After intervention, the value of forced expiratory volume in 1 s (FEV1), forced expiratory volume in one second/predicted value ratio(FEV1%pred), forced vital capacity (FVC), FEV1/FVC of the observation group were higher than those of the control group (P＜0. 05). Scores of Self-rating Anxiety Scale (SAS), Self-rating Depression Scale(SDS)in the observation group were lower than those in the control group (P＜0. 05). The total score of St George's Respiratory Questionnaire (SGRQ) and dimension scores of symptom, activity and impact in the observation group were lower than those in the control group (P＜0. 05). Conclusion Modified Morita therapy combined with motor imagery training can promote pulmonary function recovery, relieve negative emotion, and improve quality of life in COPD patients.

Background and purpose: Invasive breast carcinoma is the most prevalent malignancy in women worldwide and has a poor prognosis. Tumor xenobiotics change the tumor microenvironment and participate in the regulation of tumor occurrence, development and metastasis, which provide new ideas for the diagnosis and treatment of tumors. DZNep can target and regulate the degradation of H3K27me3 histone methyltransferase and specifically induce tumor cell apoptosis, thereby inhibiting cell proliferation and migration in a variety of tumors. In this study, we investigated the effect of DZNep on invasive breast carcinoma exosomes and observed its effect on epithelial-mesenchymal transition (EMT) of breast cancer cells by regulating intercellular junctions. Methods: EZH2 expression in invasive breast carcinoma was analyzed using the The Cancer Genome Atlas (TCGA) database and the online analysis software GEPIA2, and the Tumor Immunity Estimation Resources (TIMER) was used to analyze the relationship between EZH2 and the expressions of tumor microenvironment cytokines and EMT-related proteins. Intervention of invasive breast carcinoma MDA-MB-231 with DZNep and extraction of exosomes using differential ultracentrifugation were performed. Exosome membrane-bound protein expression was identified by detecting the expressions of CD9, CD63 and TSG101 using Western blot. The Brownian motion of exosomes was tracked and analyzed by nanoparticle tracking analysis (NTA) technique, and the hydrodynamic diameter and concentration of exosome particles were calculated in combination with the Stokes-Einstein equation. Transmission electron microscopy analysis of the size and shape of exosomes was carried out. The above methods were used to explore the changes of exogenous exosomes in breast cancer induced by DZNep. In addition, Western blot was used to detect the expressions of EZH2, intercellular junction proteins such as occludin, zonula occludens-1 (ZO-1), laminin, aquaporin 4 (AQP4), connexin 43, claudin5 and collagen Ⅵ, and EMT-related proteins such as E-cadherin and vimentin, respectively, to analyze the regulatory mechanism of DZNep on the tumor microenvironment. Results: EZH2 expression was higher in cancer tissues than in normal tissues. High EZH2 expression was positively correlated with the upregulation of both invasive breast carcinoma immune cells and stromal cells in Luminal A, positively correlated with E-cadherin, N-cadherin and vimentin expressions in invasive breast carcinoma, positively correlated with E-cadherin expression and negatively correlated with N-cadherin expression in BRCA-Luminal B, and positively correlated with N-cadherin and vimentin expressions in BRCA-Luminal A (P＜0.05). The expressions of CD9, CD63 and TSG101 showed that the exosomes of MDA-MB-231 cells were successfully extracted. After DZNep intervention, the particle size of the exosomes was significantly reduced and the number was decreased. The expressions of intercellular junction proteins including occludin, ZO-1, laminin, AQP4 and connexin 43 were decreased, and the expressions of collagen Ⅵ and claudin 5 (CLDN5) were increased. The expression of EMT-related protein E-cadherin was increased, while the expressions of vimentin was decreased. Conclusion: DZNep reduces the generation of exosomes in BRCA by inhibiting EZH2, which further alters the tumor cell microenvironment and thus affects the EMT phenomenon. [ABSTRACT FROM AUTHOR]

Objective: To observe the effects of dexmedetomidine combined with sevoflurane on cerebral oxygen metabolism and stress response in elderly patients undergoing laparoscopic gastrointestinal tumor resection. Methods: 100 elderly patients undergoing laparoscopic gastrointestinal tumor resection who were treated in our hospital from January 2020 to December 2020 were divided into control group （n=50, sevoflurane anesthesia） and study group （n=50, dexmedetomidine combined with sevoflurane anesthesia） by random number table method. Hemodynamics, stress response, cerebral oxygen metabolism, cognitive function and adverse reactions of two groups were observed. Results: 60 min （T1） to 30 min （T3） after operation, The heart rate （HR） of the two groups first decreased and then increased compared with the time point before induction of anesthesia （T0）, and the mean arterial pressure （MAP） first increased and then decreased （P<0.05）. HR at T1～T3 time points in the study group were lower than those in the control group （P<0.05）. The dopamine（DA）, epinephrine （AD） and norepinephrine （NE） levels in two groups at 3 d after operation were increased, but the study group was lower than the control group （P<0.05）. The difference of blood oxygen content （DajvO2） and cerebral oxygen uptake rate （CERO2） in both groups at 3d after operation decreased, but the study group was lower than the control group （P<0.05）. The scores of mini mental state examination scale （MMSE） in the study group at 6h, 1d and 3d after operation were higher than those in the control group （P<0.05）There was no significant difference in the incidence of adverse reactions between the two groups （P>0.05）. Conclusion: Sevoflurane combined with dexmedetomidine in elderly patients undergoing laparoscopic gastrointestinal tumor resection can effectively reduce the body’s stress response, reduce the damage of cognitive function, and maintain hemodynamic stability and cerebral oxygen metabolism.
