Abstract： Background As a neurodegenerative disease，Alzheimer's disease（AD） has a high incidence rate and rapid development，which seriously affects the quality of life of patients. In recent years，research on music therapy intervention in AD has gradually increased，lacking effective systematic evaluation and analysis. Objective A meta-analysis was conducted on the intervention effects of music in the treatment of cognition，emotion，living ability and sleep disorders in AD patients. Methods A randomized controlled trial was conducted on the intervention effect of music therapy methods on Alzheimer's patients in the Chinese Journal Full Text Database（CNKI），Wanfang Database（Wanfang），VIP Database（VIP），Medline，Elsevier ScienceDirect，PubMed，and Embase by computer search. The search time was from the establishment of each database until February 2023，and the data was analyzed using Review Manager 5.4 software. Results The study included 15 RCT studies with a total of 1 077 patients. The results of meta-analysis showed：The effects of music therapy on cognitive function（MD=4.35，95%CI=1.64 to 7.05，Z=3.15，P=0.002），negative emotion（SMD=-0.71，95%CI=-1.26 to -0.15，Z=2.51，P=0.01），life ability（SMD=-0.91，95%CI=-1.55 to -0.27，Z=2.77，P=0.006） The effect of intervention was better than that of control group. There was no significant difference in sleep disorder intervention between the two groups （MD=-1.04，95%CI=-3.10 to 1.02，Z=0.99，P=0.32）. Subgroup analysis showed that The treatment period was <12 weeks （P=0.01），the treatment duration was <45min/ time（P=0.02），the treatment frequency was ≥ 3 times/week（P<0.001），the implementation method was individual（P<0.001），the implementation method was individual + group（P=0.002），and the intervention measure was receiving music therapy（P<0.001） The effect of intervention on cognitive function in the group was better than that in the control group. Treatment period ≥ 12 weeks（P=0.004），treatment frequency <3 times/week（P=0.01），implementation method of individual + group（P=0.02），intervention measure of receiving music therapy（P=0.002），intervention measure of active music therapy（P=0.002），the intervention effect of music intervention group on negative emotions was better than the control group. Conclusion Music therapy can improve the cognitive function，mental state，and daily self activity of Alzheimer's patients. However，due to the low quality of case studies included，more large-scale and high#2;quality evidence-based studies are still needed to verify.

Abstract： People overestimate the intensity and duration of their affective reactions to events in the future. This is called impact bias (Wilson & Gilbert, 2003). Impact bias influences individuals’ satisfaction with their decision making. Few studies have shed light on how to reduce impact bias in affective forecast based on dual-process theories. According to dual-process theories of human thinking, there are two distinct but interacting systems for information processing. System 1 relies on frugal heuristics and produces intuitive responses, while System 2 relies on deliberative analytical processing. System 2 often overrides the input of System 1 when analytical thinking is activated. Thus, we here hypothesize that analytical thinking reduces the impact bias in affective forecasting.In experiment 1, a total of 240 undergraduates were assigned to play an ultimatum game as proposers and asked to predict how they would feel when their proposals were accepted or rejected by responders. At random, they were told their proposals were accepted or rejected. As soon as they knew the result, they were asked to report how they felt. Before the ultimatum game began, participants were randomly assigned to view pictures of The Thinker to prime analytical thinking or geometric figures as a control condition. The results showed that analytical thinking reduced impact bias in affective forecasting by reducing the intensity of predicted emotions.In experiment 2, a total of 52 undergraduates took part in a memory test. They were asked to predict how they would feel if their score on a memory test exceeded 90% or not before they took the test. As soon as they knew the result that they did not exceed 90%, they were asked to report how they felt. Before taking the memory test, participants were randomly assigned to perform a verbal fluency task with words related to analytical thinking to prime analytical thinking or to a verbal fluency task with words not related to analytical thinking as a control condition. The results showed that analytical thinking reduced impact bias in affective forecasting by reducing the intensity of predicted emotions.In experiment 3, a total of 111 women who had only one child were asked to predict how they would feel if they had a second. Before predicting their feelings, they were randomly assigned to view pictures of The Thinker to prime analytical thinking or geometric figures as a control condition. Results showed that analytical thinking reduced the positive affect of having the second child but not the negative affect of having the second child.In sum, the present research shows that analytical thinking reduces impact bias in affective forecasting by reducing the intensity of predicted emotions. It can help us reduce impact bias in affective forecasting when making decisions and promote satisfaction with those decisions. Limitations and further research are here discussed as well.

Abstract： Aiming at the problem that TextRank ignores syntactic information and topic information when extracting chapter keywords, propose a chapter keyword extraction model based on syntactic analysis and topic distribution. Model includes two stages of chapter keyword extraction: paragraph and chapter. Firstly, use paragraphs as a unit to extract paragraph keywords by combining word co-occurrence, grammatical and semantic information. Then cluster the paragraphs according to the paragraph topics to form the paragraph topic set. Finally, extract chapter keywords based on the distribution characteristics of paragraph topics. On the open news dataset, the model's extraction effect improves by about 10% compared with the original TextRank. Results show that the method has significantly improved the extraction effect, and prove the importance of grammatical information and topic information.

Abstract： Abstract: Objective: To investigate the influence of COVID-19 on the psychological status of residents in different regions of China in the medium term.Methods: Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale (SAS),Social Support Rating Scale (Social Support Rate) and disease awareness survey were performed on 3340 residents in different regions in China. Results: The average scores of depression (40.89 ± 10.901) and anxiety (38.35 ± 8.298) were slightly higher than the norm (P <0.05), but had no clinical significance (depression score> 53; anxiety score> 50). Compared with non-Hubei region, no significant difference was found in depression and anxiety scores. Although average score of each group in the SSRS score was> 30,the younger group was smaller than the older group (P <0.05). The disease cognition score was higher in the medical group than in the non-medical group and higher in the younger group (P <0.05). Correlation analysis showed that there was a significant negative correlation between cognition and anxiety or depression scores (P <0.05). Conclusion: Under the leadership of CPC and Chinese Government, the war against epidemic disease of COVID-19 has achieved Partial victory. The anxiety and depression of the general public, especially in Hubei, have been alleviated to some extent, however it is still slightly worse than that in non-epidemic period. The social masses, especially the elderly masses, are still relatively inadequate in understanding the COVID-19, which needs to be further popularized by the community and medical staff. Further popularization of the disease may be an effective way to eliminate anxiety and depression.

Abstract： Objective To evaluate the safety and short-term efficacy of Willis covered stent for treatment of blood blister-like aneurysms (BBA). Methods Eight patients with BBA were treated with Willis covered stent system during the period from December 2014 to February 2016. The guiding catheter was placed as high as possible to facilitate the delivery of the covered stent system. Results Nine covered stents were implanted in the aneurysms of 8 patients (8 aneurysms), and 8 stents were released successfully in the parent arteries. In 6 patients, angiography immediately after stent release showed complete disappearance of the aneurysm and the parent arteries remained patent. One patient experienced a minor endoleak after stent implantation, and another stent was implanted to eliminate the endoleak. Iatrogeniccarotid-cavernous fistula occurred in 1 patient due to tortuosity of the parent artery, for which superficial temporal artery-to-middle cerebral artery bypass combined with parent artery occlusion was performed instead; the patient recovered smoothly and the bypass remained patent at 6 months after the operation. No other periprocedural complications occurred in these patients. Follow-up study showed no new-onset neurological deficits in these 8 patients, who had mRS score of 0 in 6 patients and of 1 in 2 patients. Digital subtractive angiography at 6 months after the operation demonstrated no aneurysm in these patients, and only one patient showed mild stenosis in the parent artery. Conclusion Willis covered stents are effective for treatment of BBAwith good safety andshort-termoutcomes.

Abstract： Objective To study the pattern of DNA double-strand break (DSB) formation in S-phase cells after thermal damage and explore the mechanisms behind heat sensitivity of S-phase cells and delayed DSBs. Methods Flow cytometry was used to analyze the cell cycle arrest in H1299 cells exposed to thermal damage, and EdU incorporation assay was employed to evaluate the DNA replication capacity of the cells. The cells synchronized in S phase were obtained by serum starvation and DSBs were observed dynamically using neutral comet assay. Trypan blue dye exclusion technique was used to analyze the cell viability after thermal damage. Western blotting (WB) was used to detect the phosphorylation of ATM and DNA binding RAD18. Results The percentage of S-phase cells increased significantly after exposure of the cells to 45 ℃ for 1 h (P<0.01). The time-dependent variation pattern of EdU incorporation was similar to that of S-phase cell fraction. The comet tail began to appear only after incubation of the cells at 37 ℃ for some time and the Olive tail moment (OTM) increased with prolonged incubation. Cell death remained low until 7.5 h after heat exposure of the S-phase cells and then increased rapidly. The phosphorylation of ATM first increased but then decreased drastically. In cells with heat exposure, DNA binding RAD18 was attenuated obviously compared that in non-exposed cells. Conclusion Thermal damage causes cell cycle arrest in S phase, and delayed fatal DSBs occur in the arrested cells due to persistent replication and DNA damage repair suppression, which are the possible cause of heat sensitivity of S-phase cells.
