Objective To analyze the death rate and life loss of injuries in Jinshan District of Shanghai from 1990 to 2023, and to provide a scientific basis for the formulation of injury prevention and control measures. Methods Excel 2010 was used to establish a database for injury death reports in Jinshan District from 1990 to 2023, and the crude mortality rate, standardized mortality rate, age-specific mortality rate, potential years of life lost (PYLL), rate of potential years of life lost (PYLLR) and standardized rate of potential years of life lost (SPYLLR) were calculated. Results From 1990 to 2023, the crude mortality rate due to injuries in Jinshan District was 52.25/100 000, while the standardized mortality rate was 36.95/100 000. Based on the standardized mortality rate, the top four causes of injury-related deaths were traffic accidents, falls, drowning, and suicide. Traffic accidents ranked first as the leading cause of death for both males (19.30/100 000) and females (8.41/100 000). The top cause of death for the 0-14 years old group was drowning, the 15-64 years old group was traffic accidents, and the 65 years old and above was falls. Over the 34-year period, according to SPYLLR, the top four causes of death for both genders were consistently traffic accidents, drowning, suicide, and falls. Conclusion From 1990 to 2023, traffic accidents, falls, drowning, and suicide have been the primary causes of injury-related deaths in Jinshan District, Shanghai. It is essential to develop targeted prevention and control strategies based on the specific characteristics of these injury-related fatalities.

Objective:To investigate the status quo and influencing factors of the somatization of depressive emotions among college students, in order to provide a theoretical basis for the reform of mental health education and the formulation of operable mental health counseling for college students.Methods:Totally 297 college students from two institutions of higher education in Heilongjiang Province were selected by convenience sampling and investigated with the College Student Depressive Emotion Somatization Questionnaire, Attitudes Toward Seeking Professional Psychological Help Scale-Short Form (ATSPPH-SF), and the Type D Personality Scale (DS14) .Results:The total score for the College Student Depressive Emotion Somatization Questionnaire among the 297 students was (28.49±8.07), and the total score for the ATSPPH-SF was (21.98±2.73). Multiple linear regression analysis showed that the influencing factors for the somatization of depressive emotions in college students were professional psychological help-seeking attitudes and whether they had a Type D personality ( P < 0.05) . Conclusions:During university education, there should be a focus on students' personality traits and the positivity of their attitudes toward seeking professional psychological help in order to mitigate the occurrence of adverse psychological issues such as symptoms of depressive somatization.

Objective To investigate the clinical efficacy and safety of endoscopic resection using snares for the treatment of gastric submucosal tumors(SMTs).Methods 66 patients diagnosed with gastric SMTs and treated with endoscopic resection from August 2017 to August 2023 were retrospectively analyzed and divided into the snare group(endoscopic resection using snares,n=33)and the traditional resection group(endoscopic resection using a traditional disposable incision knife,n=33).The operation time,overall resection rate,incidence of adverse reactions,operation cost,hospitalisation cost,and the post-operative hospital days were compared between the two groups.Results The lesion diameter was 8.00(6.00,14.00)mm in the snare group and 8.00(7.50,10.00)mm in the traditional resection group,the difference between the two groups was not statistically significant(P>0.05);The operative time in the snare group was significantly shorter than that in the traditional resection group[26.00(19.00,30.50)min vs 33.00(22.50,49.50)min],the difference was statistically significant(P<0.05);The overall resection rate in both groups was 100.0%;Neither group of patients had intraoperative perforation.There were no statistically significant differences in the incidence of adverse reactions such as intraoperative bleeding,abdominal pain and fever between the two group(P>0.05);The operative cost of the snare group was significantly lower than the traditional endoscopic resection group[(8 642.18±1 078.56)yuan vs(13 266.45±2 160.80)yuan],the difference was statistically significant(P<0.05).Conclusion Compared with traditional surgical instruments,endoscopic resection of gastric SMTs using snares has a shorter operating time,lower surgical costs,safe and effective,making it worthy of promotion.

Objective:To explore the mediating effect of negative cognitive processing bias between type D personality and depression after percutaneous coronary intervention (PCI) .Methods:Using the convenient sampling method, a total of 340 patients who underwent PCI for the first time in Department of Cardiology in the Second Affiliated Hospital of Harbin Medical University from September to December 2021 were selected as the research objects. The General Demographic Data Questionnaire, Type D Personality Scale (DS14), Negative Cognitive Processing Bias Questionnaire (NCPBQ) and Beck Depression Inventory-Ⅱ (BDI-Ⅱ) were used to investigate. Spearman correlation analysis was used to determine the correlation between type D personality, negative cognitive processing bias and depression. The mediating effect model was established by AMOS 24.0 software to analyze the mediating effect of negative cognitive processing bias between type D personality and depression.Results:A total of 340 questionnaires were sent out in this study, and 317 valid questionnaires were recovered, with an effective questionnaire recovery rate of 93.2%. The total score of Type D Personality Scale of 317 patients after PCI was (18.05±4.15), in which the score of negative affectivity dimension was (9.51±2.33) and the score of social inhibition dimension was (8.54±2.61). The proportion of patients with type D personality is 24.9% (79/317). The score of Beck Depression Inventory-Ⅱ (BDI-Ⅱ) was (9.52±4.83), and the incidence of depression was 20.2% (64/317). Correlation analysis showed that D-type personality of patients, negative cognitive processing bias and depression were positively correlated ( P<0.05). The mediating effect analysis showed that type D personality could directly affect the occurrence of depression (effect size 0.431, P<0.001), or indirectly through negative cognitive processing bias (effect size 0.145, P<0.001) . Conclusions:The negative cognitive processing bias is an important factor in the occurrence of depression in patients with CHD and with type D personality. Improving the negative cognitive processing bias will help reduce the occurrence of depression and improve the prognosis.

Objective:To explore the effect of network learning environment on critical thinking ability of nursing undergraduates.Methods:From September 2021 to January 2022, a total of 84 nursing undergraduates in the third grade of Nursing School of Harbin Medical University were selected as the research objects.

The total score of Online Learning Environment Scale of nursing undergraduates was positively correlated with the total score of Chinese version of Critical Thinking Ability Scale of nursing undergraduates ( P<0.01) . The results of multiple linear regression analysis showed that the influencing factors of critical thinking ability of nursing undergraduates included family economic situation, whether they could receive free online database resources from schools, and online learning environment ( P<0.05) . Conclusions:The online learning environment for nursing undergraduates is at a moderate level. It is suggested that nursing undergraduates should optimize the content and form of online learning and provide targeted learning support resources so as to improve the critical thinking ability of nursing undergraduates.

Objective:To explore the effect of online and offline blended scenario simulation teaching in the practice of nursing undergraduates.Methods:From August 2020 to May 2021, convenience sampling was used to select 76 nursing undergraduates in the class of 2017 who practiced in the Cardiology Department of the Second Affiliated Hospital of Harbin Medical University as the research object. The undergraduates were randomly divided into the experimental group and the control group, 38 in each group. The control group received the traditional graduation practice training, and the experimental group received online and offline blended scenario simulation teaching on this basis. After the practice, the clinical thinking ability of the two groups of students was evaluated by the Clinical Thinking Ability Evaluation Scale, the clinical practice ability of the two groups of students was evaluated by the Objective Structured Clinical Examination (OSCE) , and a teaching satisfaction survey was conducted.Results:The total score of clinical thinking ability, critical thinking ability, systematic thinking ability, evidence-based thinking ability, OSCE total score of the students in the experimental group were higher than those in the control group, and the differences were statistically significant ( P<0.05) . The students in the experimental group thought that the teaching method was helpful for in-depth understanding and application of theoretical knowledge, improving nursing assessment skills, clinical coping skills and communication skills, and at the same time helping to cultivate critical thinking and teamwork awareness, and arouse learning enthusiasm, and the differences were statistically significant (all P<0.05) . Conclusions:The online and offline blended scenario simulation teaching can effectively improve the clinical thinking ability, clinical practice ability and teaching satisfaction of nursing undergraduates, and it has good effect in the graduation practice of undergraduate nursing students.

Objective:To explore the characteristics of attention bias in patients with type D personality coronary heart disease (CHD), and provide a new theoretical perspective for elucidating the effect of type D personality on the pathogenesis of CHD and formulating prevention strategies.Methods:From March 2021 to September 2021, a total of 40 CHD patients who were hospitalized in the 2nd Affiliated Hospital of Harbin Medical University were enrolled using the convenient sampling method and event-related potential (ERP). Patients were divided into the type D personality group and the non-type D personality group by Type D Personality Scale-14, and matched according to age, gender and years of education. The Self-Rating Depression Scale was used to exclude patients with depression. The Negative Cognitive Processing Bias Questionnaire (NCPBQ) was used to measure negative cognitive processing bias. Dot-probe task and ERP technology were used to analyze the characteristics of attention bias, with the emotional face images as experimental stimulation materials.Results:A total of 15 CHD patients with type D personality and 15 CHD patients without type D personality were enrolled. The scores of NCPBQ and negative rumination bias dimension of CHD patients with type D personality were higher than those of CHD patients without type D personality, and the differences were statistically significant ( P<0.05). Behavioral experiments data showed that CHD patients without type D personality had a shorter response time to positive face images than negative face images in inconsistent conditional stimulation ( F=10.646, P<0.05), CHD patients without type D personality had a shorter response time to negative face images in consistent prompt type than inconsistent prompt type ( F=4.744, P<0.05). ERP experimental data showed that CHD patients with type D personality has higher N1 amplitude facing negative and positive face images stimulation ( F=8.973, P<0.05), CHD patients without type D personality had higher P3 amplitude facing positive face images stimulation ( F=6.750, P<0.05) . Conclusions:CHD patients with type D personality patients have negative cognitive processing bias, and they are more sensitive to emotional stimulation, invest more attention in the early stage of cognitive process, and have difficulty in disengaging attention from negative stimulation. Clinical medical staff should reduce negative stimulation and carry out positive psychological intervention in CHD patients with type D personality to reduce the adverse effects of negative stimulation on the prognosis of patients.

Objective:To explore the risk factors for esophageal stricture after endoscopic resection (ER) of large-area early esophageal cancer (≥3/4 circumferential mucosal defect).Methods:A total of 63 cases of large-area early esophageal cancer treated with ER in the Digestive Endoscopy Center of the First Medical Center of PLA General Hospital from May 2009 to April 2016 were included in the retrospective analysis. They were divided into stricture group (32 cases) and non-stricture group (31 cases) according to the occurrence of postoperative esophageal stenosis. T-test or Chi square test was conducted to compare the indicators between the two groups. Indicators of P<0.05 and potential indicators from the clinical perspective were included in multivariate logistic regression analysis. Results:Univariate analysis showed that the length of lesion, the degree of mucosal defect around the wound and the injury of muscularis propria were associated with esophageal stricture after ER ( P<0.05). The above 3 indicators were included in the multivariate logistic regression analysis, together with 3 other indicators, i. e. preventive measures for stenosis, pathological type, and en bloc resection. The results showed that more than 7/8 circumferential mucosal defect around the wound (VS 3/4-<7/8 circumferential: P=0.028, OR=0.317, 95% CI:0.114-0.884) and no preventive measures ( P=0.002, OR=0.153, 95% CI:0.046-0.512) were independent risk factors for esophageal stricture after ER of large-area early esophageal cancer. Conclusion:Circumferential mucosa defect≥7/8 is the main factor leading to esophagus stricture after large-area early esophagus carcinoma. And appropriate preventive measures can effectively reduce the incidence of postoperative stenosis after ER.
