Objective To investigate effectiveness of meta-cognitive intervention on aged people with middle depression. Methods Geriatrist Depression Scale(GDS) and Hamilton's Depression Scale ( HAMD-17 ) were used to screen out 70 aged people with middle depression from 850 retired soldier cadres dwelling in cpla dalian sanitarium. They were randomly divided into study group( n = 35 ) and control group( n = 35 ). The experimental group received meta-cognitive intervening and general nursing care for 8 weeks, while the control group only received general nursing care for 8 weeks. HAMD-17, GDS, global assessment scale(GAS) and the Metacognitions Questionnaire(MCQ-30) were administered both at the start and the end of the 8th week. Results The total scores in HAMD and GDS were decreased significantly in study group ( HAMD: ( 1 1.54 ± 2.50 ) vs ( 13.06 ±2.82),t= -2.378, P=0. 020;GDS:(12.51 ±2.43) vs (16.06 ±2.48), t= -6. 031, P=0. 000;GAS:(77.71 ±3.03) vs (75.63 ± 3.24), t = 2. 785, P = 0. 007 ). At the end of 8th week, the MCQ total score was significantly decreased in study group (38.69 ± 4. 17,81.37 ± 5.98, t = 34. 652, P ＜ 0. 01 ). Conclusion For aged people with middle depression,good effects are got by the meta-cognitive intervening technique and meta-cognitive intervening technique improve the meta-cognitive level of aged people with middle depressive mood.

Objective To investigate the effects of different irradiation techniques on dose distribution in target volume and normal tissues after the radical surgery for gastroesophageal junction adenocarcinoma,and to provide the optimal regimen for clinical treatment.Methods A total of 9 patients with gastroesophageal junction adenocarcinoma who underwent radical esophagus-proximal gastrectomy or total gastrectomy were enrolled.The therapeutic regimens of five-field static intensity-modulated radiotherapy (IMRT),volumetric-modulated arc therapy (VMAT),and helical tomotherapy (HT) were designed for each patient,and the dose-volume histogram was used to evaluate the effects of different irradiation techniques on the conformity index (CI) and homogeneity index (HI) of target volume and the surrounding normal tissues. The prescribed dose was 45 Gy at 1.8 Gy/fraction.The patients received oral S-1 as concurrent chemotherapy at a dose of 80 mg/(m 2? d) twice a day during radiotherapy.Results Compared with IMRT and VMAT,HT had better CI and HI of the target volume,as well as a better protective effect on the intestinal tract and bone marrow.Compared with IMRT and HT,VMAT had a lower V20 and V30 for the left kidney and a lower V30 for the heart,while IMRT had lower V5 and V10 for both lungs;V20 and mean dose showed no significant differences between the three techniques.HT had the highest mean sub-field hop count,followed by IMRT and VMAT.Conclusions IMRT, VMAT, and HT can meet the clinical requirements,but besides ensuring the best CI and HI of the target volume,HT has a good protective effect on the intestine and spinal cord and can help to reduce the incidence of adverse events in patients.

Attention level evaluation refers to the evaluation of people's attention level through observation or experimental testing, and its research results have great application value in education and teaching, intelligent driving, medical health and other fields. With its objective reliability and security, electroencephalogram signals have become one of the most important technical means to analyze and express attention level. At present, there is little review literature that comprehensively summarize the application of electroencephalogram signals in the field of attention evaluation. To this end, this paper first summarizes the research progress on attention evaluation; then the important methods for electroencephalogram attention evaluation are analyzed, including data preprocessing, feature extraction and selection, attention evaluation methods, etc.; finally, the shortcomings of the current development in the field of electroencephalogram attention evaluation are discussed, and the future development trend is prospected, to provide research references for researchers in related fields.

Objective To observe the incidence of adverse reactions and short-term efficacy of S-1 and concurrent intensity-modulated radiotherapy ( IMRT) for locally advanced gastric cancer in a phase Ⅱclinical trial based on the phase I clinical trial.Methods Patients pathologically diagnosed with stage TN (+) gastric adenocarcinoma with local or distal metastasis after R0 resection were enrolled as subjects.IMRT was delivered 5 times per week with a total dose of 45 Gy in 25 fractions.S-1 was orally administered on the day of radiotherapy at a dose of 80 mg/m2 .Results A total of 40 patients, consisting of 6 patients from the phase I trial and 34 patients from the phaseⅡtrial, were enrolled in this study.In those patients, the age ranged between 27 and 73 years ( median age 50 years) and the male-to-female ratio was 3:1.Thirty-nine ( 98%) out of the forty patients completed radiotherapy and thirty-five ( 88%) completed concurrent chemotherapy.The most common grade 3-4 adverse reactions were nausea/anorexia ( 13%) , leukopenia ( 10%) , vomiting ( 8%) , radiation esophagitis ( 5%) , and neutropenia ( 5%) .There was no perioperative death.The 2-year overall survival and disease-free survival rates were 74% and 77%, respectively. Conclusions Postoperative S-1 and concurrent IMRT achieve satisfactory outcomes and tolerable toxicity in patients with locally advanced gastric cancer.

Sleep is essential for the maintenance of human normal functions.Nowadays,the occurrence of active sleep deprivation(ASD)or passive sleep depriva-tion(PSD)is becoming more and more common due to the inability of the body adapting to the rapid changes in the internal and external environment.SD is not only an action,a brief process or a result,but also a directly or indirectly sustained state,which is associated to sleep time,circadian rhythm or sleep quality.SD can lead to numerous adverse effects on the body,such as sleep-related acute and chronic diseases.Long-term SD increases the risk of neurological and cardiovascular dis-eases as well as immune system dysfunction.In addi-tion,SD may affect the reproductive health of the body,giving rise to a series of potential fertility problems.In recent years,the correlation research and mechanism between SD and the related diseases have become a focus of scholars' attention.Numerous lines of evidence suggest that pathological sleep,such as insomnia and sleep apnea syndrome,is associated with impaired repro-ductive function.Disruptions in the circadian rhythm can also lead to impaired hypothalamic-pituitary-gonadal(HPG)axis function and thereby interfere with the repro-ductive process.Our research team has demonstrated that SD significantly affects the fertility of male and female rats and has adverse effects on reproduction.By new generation sequencing(NGS)and RT-PCR verifica-tion,we have identified differently expressed genes that are involved in mediating the effect of SD on fertility.However,the mechanisms and biological macromolecules regulated by SD are worthy of being further explored.This paper provides a brief review of SD research and then focuses on the adverse impact of SD on fertility,conducting a literature review to sort out the ideas and pro-vide references for research in this field.

The incidence and mortality of esophageal cancer are high, with strong invasiveness and poor prognosis. In China, the number of morbidity and death accounts for about half of the world. The cause of the disease has not yet been clarified, and it is known to be related to many factors such as chronic damage to the upper digestive tract caused by poor diet and lifestyle, heredity and environment. With the continuous advancement of molecular biology technology, metagenomics and high-throughput sequencing began to be used as non-culture methods instead of traditional culture methods for micro-ecological analysis, and is becoming a research hotspot. Many studies have shown that the disturbance of upper digestive tract microecology may be one of the causes of esophageal cancer, which affects the occurrence and development of esophageal cancer through complex interactions with the body and various mechanisms. This paper reviews the research progress, which is of great significance to further clarify the value of upper gastrointestinal microecology in the pathogenesis, diagnosis and treatment of esophageal cancer.

Objective:To investigate the relevant situation of the emergency departments (ED) of general hospitals at all levels in Zhejiang Province participating in the prevention and control of Corona Virus Disease 2019 (COVID-19), and to provide a reference for further improving the capacity of emergency services.Methods:A multi-center cross-sectional investigation study was jointly initiated by the Zhejiang Provincial Emergency Medicine Quality Control Center, the Emergency Medicine Branch of Zhejiang Medical Association, and the Emergency Physicians Branch of Zhejiang Medical Doctors Association. Before investigation, experts were organized to develop a special questionnaire. Then the ED of general people's hospitals or Chinese Medicine hospitals at the county/district-level or above were included and their participations in the prevention and control of COVID-19 epidemic between March 9, 2020 and March 15, 2020 were investigated. The collected information included: basic information of the hospitals; participation of ED in fever clinics; the number of COVID-19 patients admitted to ED; the situation of ED support to the anti-epidemic front-line; and the epidemic prevention facilities of ED, and the early supply of medical protective equipments.Results:A total of 181 hospitals from 11 prefectures and cities across the province were finally included, including 52 (28.7%) Grade-A tertiary hospitals, 45 (24.9%) Grade-B tertiary hospitals, 64(35.4%) Grade-A secondary hospitals, and 20 (11.0%) Grade-B secondary or lower hospitals. Among them, 93 (51.4%) were COVID-19 designated hospitals, and 49 (27.1%) had the ability to detect COVID-19 nucleic acid; 177 (97.8%) set up independent fever clinics and 33 (18.6%) were managed by ED alone or mainly. The medical staffs of 65 (36.7%) fever clinics were all or mainly from ED. A total of 213 cases of COVID-19 were received/treated in 40.3% ED, accounting for 17.3% of the total number of cases in Zhejiang Province. A total of 3 848 doctors and nurses supported the front-line of epidemic prevention, of them, 253 supported Hubei Province (accounting for 12.5% ??of the total number). There were 68.5% and 76.8% ED having spare separate clinic and ordinary rescue single room to deal with the COVID-19. In addition, at the early days of anti-epidemic, more than 50% ED were in short supply or even had no medical protective equipment.Conclusions:The ED of Zhejiang Province plays an important role and has made a great contribution to the prevention and control of the COVID-19 epidemic. It is necessary to improve the conditions of ED to effectively respond to the prevention and control of daily infectious diseases.

Objective:To analyze the diagnosis, treatment and prognosis of patients with rare malignant tumors of the temporal bone. Methods:Four cases of rare temporal bone malignant tumors in our hospital between March 2014 and December 2020 were reviewed, including two cases of chondrosarcoma, one case of fibrosarcoma and one case of endolymphatic cystic papillary adenocarcinoma. There were three males and one female, ages between 28 and 56 years at the time of surgery. Common symptoms included hearing loss, facioplegia, tinnitus, and headache. All patients underwent imaging examinations to evaluate the extent of the lesions. Tumors were removed by subtotal temporal bone resection or infratemporal fossa approach, and postoperative adjuvant radiotherapy was applied if necessary. Results:One of the two chondrosarcoma patients was cured by complete resection of the tumor for 75 months, the other one recurred after the first excision of the tumor and underwent infratemporal fossa approach resection of skull base mass again with no recurrence found yet for 112 months. One patient with fibrosarcoma survived for 28 months after surgery with a positive margin and post-operative radiotherapy. One patient with endolymphatic cystic papillary adenocarcinoma recurred 12 months after subtotal lithotomy, and underwent subtotal temporal bone resection again, combined with radiotherapy. No recurrence was found for 63 months. Conclusion:The incidence of rare temporal bone malignant tumors is extremely low, the location is hidden, and the symptoms are atypical. Attention should be paid for early detection and early treatment. Surgical resection is the main treatment, and radiotherapy can be supplemented in the advanced stage or with a positive margin.
