Objective:To explore the psychological experiences of lung cancer patients during treatment based on the perspective of narrative medicine,and to provide references for targeted nursing interventions.Methods:Guided by the concept of narrative medicine,the phenomenological method of qualitative research was used to conduct in-depth interviews with 20 lung cancer patients.The interview data were analyzed,refined,and summarized by using the content analysis method.Results:From the perspective of the humanistic value of narrative medicine,four themes were extracted from the interview contents with 20 lung cancer patients,including the loss of patients'role identity,the experience of disease uncertainty,the fear and expectation of death,and the helplessness and perception of life.Conclusion:During the treatment process of lung cancer patients,there are negative psychological experiences,such as loss of role identity,uncertainty of disease,fear of death,and hope to leave with dignity.Meanwhile,there are positive perceptions,such as contemplation of the meaning of life and actively coping with it.

Objective:To investigate the protective effect of hyperbaric oxygen therapy(HBOT)on myocardial fibrosis and oxidative stress induced by D-galactose(D-gal)in senescent model mice and its possible mechanism.Methods:Three-month-old male Kunming mice(n=27)were randomized into control, D-gal, and D-gal + HBOT groups.The control group received subcutaneous sterilized saline(5 ml · kg -1· d -1)for 8 weeks; the remaining 2 groups received subcutaneous D-gal(200 mg · kg -1· d -1)for 8 weeks. The D-gal + HBOT group underwent HBOT intervention at week 7~8.At the end of the experiment, the histopathological changes were analyzed by hematoxylin-eosin(HE)staining, and the fibrosis changes were analyzed by Masson staining and Sirius red staining.Oxidative stress kit was used to detect catalase(CAT), total superoxide dismutase(T-SOD)activity and malon-di-aldehyde(MDA)content in serum of mice.Western blotting was used to detect the expression levels of the aging-related proteins p53 and p16 in mouse heart tissue, the heart-function-related proteins atrial natriuretic peptide(ANP)and brain natriuretic peptide(BNP), and the oxidative stress-related protein superoxide dismutase 1(SOD1), superoxide dismutase 2(SOD2)and catalase(CAT). Results:Cardiac morphologic staining indicated that as compared with the control group, mice of D-gal group exhibited features of senescence and the increased fibrosis area, and senescence and fibrosis were obviously improved after HBOT intervention as compared with the D-gal group.The findings of the oxidative stress kit measurement indicated that as compared with the control group, the D-gal group had markedly decreased activities of CAT and T-SOD, significantly increased MDA content in the serum.After HBOT treatment, as compared with d-gal group, serum CAT and T-SOD activities were increased, while MDA content was decreased( F=126.85, 32.89, 157.50, all P<0.05).Furthermore, as compared with the control group, the D-gal group had obviously increased contents of p53, p16, ANP and BNP, while the content of CAT, SOD1 and SOD2 were obviously decreased.After HBOT intervention, as compared with the D-gal group, the contents of p53, p16, ANP、BNP were reduced, while the content of CAT, SOD1 and SOD2 were increased( F=36.37, 14.81, 23.28, 58.41, 12.79, 80.08, 6.63, all P<0.05). Conclusions:HBOT intervention could protects against cardiac injury in aging mice, which may be related to attenuating myocardial fibrosis, inducing the expression of antioxidant enzymes, and reducing oxidative stress.

Objective To systematically evaluate the efficacy and safety of immune checkpoint inhibitors in the treatment of advanced gastric cancer or gastroesophageal junction cancer (GC/GEJC). Methods CNKI, Wanfang, PubMed, EMBASE, ClinicalTrials, Cochrane Library and other databases were searched to collect the clinical trials of immune checkpoint inhibitors in the treatment of advanced GC/GEJC. The retrieval time was from the inception to Nov. 2019. Outcome measures mainly included ORR, DCR, PFS, OS and toxicities. The adoption rate difference and hazard ratio were effect measures. Meta-analysis was performed using RevMan 5.3 software. Results We included seven literatures with a total of 1949 patients. Meta-analysis showed that for the patients with advanced GC/GEJC, the second-line or later immune checkpoint inhibitor therapy improved the overall survival rate at 12 and 18 months; the OS of the patients was prolonged, compared with chemotherapy/placebo therapy (all P < 0.05). The incidence of adverse reactions of any grade or ≥grade 3 caused by immune checkpoint inhibitor therapy was lower than that caused by chemotherapy/placebo. Conclusion Immune checkpoint inhibitor treatment could improve survival endpoints in some patients with advanced GC/GEJC, and the incidence of common adverse reactions is low.

OBJECTIVE：To eval uate the effect of pharmacists intervention on opioid treatment and management in outpatients with cancer pain under multidisciplinary team （MDT）mode. METHODS ：Totally 120 outpatients with cancer pain were selected from outpatient department of our hospital from Jan. 2016 to Dec. 2018，and divided into observation group and control group according to random number table method ，with 60 cases in each group. After 1 month follow-up ，patients in the control group were given opioid analgesics and routine intervention according to pain degree ，while patients in the observation group were given same treatment as control group and pharmacist intervention based on MDT. The pain condition ，medication compliance condition ， quality of life （QOL）score，the incidence of ADR and satisfaction degree were observed in 2 groups before and after intervention . RESULTS：Follow-up were completed in 2 groups. After intervention ，NRS scores of 2 groups were significantly lower than before intervention；the observation group was significantly lower than the control group ；medication compliance scores and QOL scores of 2 groups were significantly higher than before intervention ，the observation group was significantly higher than the control group at the same time . With the prolongation of treatment time ，the number of patients with mild pain and general medication compliance in 2 groups increased gradually ，and the observation group were significantly higher than the control group at the same time；the number of patients with moderate , severe pain and low medication compliance were significantly decreased gradually ， and the observation group was significantly lower than the control group at the same time. The number of patients with good medication compliance in the observation group was significantly higher than that in the same group before intervention and the control group at the same time （P＜0.05 or P＜0.01）. There was no significant difference in the incidence of ADR between 2 groups（P＞0.05）. The satisfaction of pain control results ，doctors’treatment and pharmacists follow-up in the observation group were significantly higher than control group （P＜0.05 or P＜0.01）. CONCLUSIONS ：Under MDT mode ，pharmacists participating in the management of opioid treatment for cancer pain outpatients can effectively relieve the pain ，and improve the medication compliance and quality of life .

Brain-computer interface (BCI) provides a direct communicating and controlling approach between the brain and surrounding environment, which attracts a wide range of interest in the fields of brain science and artificial intelligence. It is a core to decode the electroencephalogram (EEG) feature in the BCI system. The decoding efficiency highly depends on the feature extraction and feature classification algorithms. In this paper, we first introduce the commonly-used EEG features in the BCI system. Then we introduce the basic classical algorithms and their advanced versions used in the BCI system. Finally, we present some new BCI algorithms proposed in recent years. We hope this paper can spark fresh thinking for the research and development of high-performance BCI system.
