Objective: To investigate the characteristics of mortality of injury among residents in Gusu District, Suzhou City, Jiangsu Province from 2013 to 2023, so as to provide the evidence for developing targeted measures of injury prevention and control. Methods: Gender, age and underlying cause of deaths due to injury in Gusu District were collected through Death Reporting Information System of Chinese Disease Prevention and Control Information System and Jiangsu Death Reporting Information System from January 1, 2013 to December 31, 2023. The crude mortality, Chinese-standardized mortality and world-standardized mortality of injury were analyzed, and the trend in mortality was analyzed using annual percent change (APC). Results: Totally 4 217 deaths due to injury were reported in Gusu District from 2013 to 2023. The crude, Chinese-standardized and world-standardized mortality rates were 51.58/105, 23.24/105 and 21.98/105, respectively, all showing a tendency towards a rise (APC=6.802%, 2.688% and 2.823%, all P<0.05). The crude mortality rate of injury was higher in women than in men (54.61/105 vs. 48.41/105, P<0.05). The five most common causes of injury included fall (32.99/105), traffic accidents (6.03/105), suicide (4.23/105), drowning (3.00/105) and asphyxia (2.16/105), accounting for 93.86% of the total number of deaths. The crude mortality rates of fall, suicide and asphyxia appeared a tendency towards a rise (APC=9.724%, 6.333% and 5.638%, all P<0.05). The crude mortality rates of injury among men, women and overall residents appeared a tendency towards a rise with age (all P<0.05). Fall was the primary cause of injury death among residents aged 65 years and above, and suicide was the primary cause of injury death among residents aged 15 to 44 years. Conclusions The crude mortality of injury appeared a tendency towards a rise in Gusu District from 2013 to 2023. The main causes of death were fall, traffic accidents, suicide, drowning and asphyxia, with the crude mortality of fall, suicide and asphyxia showing an upward trend.

Objective:To analyze the impact of cecal ligation and puncture (CLP)-induced sepsis on the proliferation and differentiation of intestinal epithelial cells.Methods:① Animal experiment: sixteen male C57BL/6 mice were divided into sham operation group (Sham group) and CLP-induced sepsis model group (CLP group) by random number table method, with 8 mice in each group. After 5 days of operation, the jejunal tissues were taken for determination of leucine-rich-repeat-containing G-protein-coupled receptor 5 (LGR5) and intestinal alkaline phosphatase (IAP) by polymerase chain reaction (PCR). The translation of LGR5 was detected by Western blotting. The expression of proliferating cell nuclear antigen (Ki67) was analyzed by immunohistochemistry. IAP level was detected by modified calcium cobalt staining and colorimetry. Immunofluorescence staining was used to detect the expression of Paneth cell marker molecule lysozyme 1 (LYZ1) and goblet cell marker molecule mucin 2 (MUC2). ② Cell experiment: IEC6 cells in logarithmic growth stage were divided into blank control group and lipopolysaccharide (LPS) group (LPS 5 μg/mL). Twenty-four hours after treatment, PCR and Western blotting were used to analyze the transcription and translation of LGR5. The proliferation of IEC6 cells were detected by 5-ethynyl-2'-deoxyuridine (EdU) staining. The transcription and translation of IAP were detected by PCR and colorimetric method respectively.Results:① Animal experiment: the immunohistochemical results showed that the positive rate of Ki67 staining in the jejunal tissue of CLP group was lower than that of Sham group [(41.7±2.5)% vs. (48.7±1.4)%, P = 0.01]. PCR and Western blotting results showed that there were no statistical differences in the mRNA and protein expressions of LGR5 in the jejunal tissue between the CLP group and Sham group (Lgr5 mRNA: 0.7±0.1 vs. 1.0±0.2, P = 0.11; LGR5/β-actin: 0.83±0.17 vs. 0.68±0.19, P = 0.24). The mRNA (0.4±0.1 vs. 1.0±0.1, P < 0.01) and protein (U/g: 47.3±6.0 vs. 73.1±15.3, P < 0.01) levels of IAP in the jejunal tissue were lower in CLP group. Immunofluorescence saining analysis showed that the expressions of LYZ1 and MUC2 in the CLP group were lower than those in the Sham group. ②Cell experiment: PCR and Western blotting results showed that there was no significant difference in the expression of LGR5 between the LPS group and the blank control group (Lgr5 mRNA: 0.9±0.1 vs. 1.0±0.2, P = 0.33; LGR5/β-actin: 0.71±0.18 vs. 0.69±0.04, P = 0.81). The proliferation rate of IEC6 cells in the LPS group was lower than that in the blank control group, but there was no significant difference [positivity rate of EdU: (40.5±3.8)% vs. (46.5±3.6)%, P = 0.11]. The mRNA (0.5±0.1 vs. 1.0±0.2, P < 0.01) and protein (U/g: 15.0±4.0 vs. 41.2±10.4, P < 0.01) of IAP in the LPS group were lower than those in the blank control group. Conclusion:CLP-induced sepsis inhibits the proliferation and differentiation of intestinal epithelial cells, impairing the self-renewal ability of intestinal epithelium.

Objective:To construct a model of nursing teaching rounds in dental clinics, and to provide a reference for the implementation of nursing teaching activities in dental clinics.Methods:Using the constructivism learning theory framework, we developed a preliminary draft of a teaching rounds model for dental outpatient nursing according to literature review, cross-sectional survey, and brainstorming results. Two rounds of Delphi consultation with 21 experts from across China were conducted to determine the teaching rounds model for dental outpatient nursing. Data entry and statistical analysis were performed with Excel 2016 and SPSS 26.0 software.Results:In the two rounds of expert consultation, the questionnaire response rates were both 100%; the expert authority coefficients were 0.865 and 0.873, respectively; and the Kendall's coefficients of concordance were 0.116 and 0.164, respectively. The established dental outpatient nursing teaching rounds model included 7 first-level items and 22 second-level items.Conclusions:The dental outpatient nursing teaching rounds model constructed in this study is scientific, reliable, and practical, which can provide guidance for conducting nursing teaching rounds in dental clinics.

Objective:To explore the chain mediating effect of anxiety and flow experience on perceived stress and mobile phone addiction in nursing college students.Methods:In December 2021, a cross-sectional design survey was conducted on 4 179 freshmen and sophomores in a nursing college in Heilongjiang Province. The Chinese perceived stress scale, generalized anxiety disorder-7, flow state scale, and mobile phone addiction tendency scale were selected separately to assess perceived stress, anxiety symptoms, flow experience and mobile phone addiction. SPSS 26.0 software was used for descriptive analysis, independent sample t-test, Spearman correlation analysis, and AMOS 24.0 software was used for mediating effect test. Results:(1) Among the 3 050 nursing students, there were 714(23.41%) students who were addicted to mobile phones. (2) Spearman correlation analysis indicated that perceived stress(27.31±9.56) was positively correlated with anxiety(7.00(1.00, 10.00), r=0.441, P<0.05), flow experience((12.00±3.40), r=0.517, P<0.05), and mobile phone addiction((42.42±13.05), r=0.476, P<0.05).Anxiety was positively correlated with flow experience ( r=0.430, P<0.01) and mobile phone addiction ( r=0.538, P<0.01).Flow experience was positively correlated with mobile phone addiction ( r=0.490, P<0.01). (3) Anxiety and flow experience played seperate mediating and chain mediating roles between perceived stress and mobile phone addiction, accounting for 26.06%(0.165/0.633), 23.54%(0.149/0.633) and 3.48%(0.022/0.633) of the total effect. Conclusion:Perceived stress not only directly affects the mobile phone addiction of nursing students, but also indirectly affects mobile phone addiction through the independent and chain mediating effects of anxiety and flow experience.

Infantile hemangioma (IH) is the most common benign tumor in infants and young children, with a typical period of proliferation and regression. However, some infantile hemangioma grows rapidly, affects function and even endangers life, and requires active treatment. In recent years, the risk factors for infantile hemangioma have become a hot topic of research. This paper reviews the research status of the risk factors for infantile hemangioma from the aspects of genetic factors and maternal factors, so as to provide help for early clinical diagnosis and treatment.

Objective:To analyze the clinical features, differential diagnosis, treatment and prognosis of complex lymphatic malformations.Methods:The clinical data of patients with complex lymphatic malformation were retrospectively analyzed from April 2010 to April 2022 in the Multidisciplinary Outpatient Department of the Vascular Disease Team of West China Hospital, Sichuan University. All patients were diagnosed with complex lymphatic malformation after consultation with multidisciplinary experts in pediatric surgery, radiology, plastic surgery, pathology, rehabilitation and other departments. The clinical manifestations, blood routine, coagulation function, magnetic resonance imaging and treatment methods of the patients were analyzed. According to the follow-up and disease results, the patients were divided into improvement, stability, progress and death.Results:A total of 18 patients with complex lymphatic malformations were included in the study, including 6 males and 12 females. The age of first diagnosis ranged from 1 month to 29 years old, and the median age was 2.5 years old. Patients were followed up and treated for 0.4 to 12.0 years, with an average follow-up of 3.5 years. Ten patients had pleural and pericardial effusion; 15 patients had visceral involvement which showed multifocal changes in imaging examinations; 9 cases were accompanied by bone destruction, which in Gorham-Stout disease patients broke through the cortex while in generalized lymphatic anomalies it did not; 14 patients had various degrees of coagulation abnormalities, of which 8 patients with severe coagulation dysfunction were all diagnosed as kaposiform lymphangiomatosis. Of the 18 patients, one kaposiform lymphangiomatosis patient died; six patients progressed; eight patients were stable; and three patients improved.Conclusion:The clinical characteristics of patients with complex lymphatic malformations are systemic, diverse and complex. The clinical symptoms of patients with diffuse lymphatic malformation accompanied by involvement of bone and multiple internal organs, chest and abdominal effusion, and coagulation dysfunction should be considered as complex lymphatic malformation. However, due to overlapping clinical characteristics of each subtypes, it is difficult to distinguish patients with complex lymphatic malformation, and the curative effect and prognosis are poor. Precision targeted drugs are the future research direction for the treatment of such diseases.
