Objective To retrieve, evaluate, and summarize evidence on preventive management of high output and dehydration in ileostomy patients from both domestic and international sources. Methods Based on the "6S" evidence model, a top-down approach was employed to retrieve evidence on prevention and management of high output and dehydration in ileostomy patients. Databases searched included BMJ best practice, UpToDate, National Guideline Clearinghouse (NGC), National Institute for Health and Care Excellence (NICE), Scottish Intercollegiate Guidelines Network (SIGN), Registered Nurses' Association of Ontario (RNAO), Wound Ostomy and Continence Nurses Society (WOCNS), World Council of Enterostomal Therapists (WCET), Medlive Clinical Guidelines website, Joanna Briggs Institute (JBI), Cochrane Library, Embase, PubMed, Web of Science, CNKI, Wanfang Data, China Biology Medicine (CBM), and VIP Database. The search period was from January 2019 to April 2024. Results A total of 13 articles were included after retrieval and screening, comprising 2 guidelines, 2 expert consensuses, 4 systematic reviews, 4 evidence summaries, and 1 clinical decision aid. After translation, summarization, and organization of the included articles, 19 pieces of evidence across 11 categories were formulated, focusing on four items: definition and risk factors of high output in ileostomy, prevention and management strategies related to high output in ileostomy, prevention and management strategies related to dehydration in high-output ileostomy, and follow-up strategies for prevention of high output and dehydration after ileostomy surgery. Conclusion The evidence summarized based on the "6S" evidence model for prevention and management of high output and dehydration in ileostomy patients can provide a reference for clinical practice among healthcare professionals and medical decision-makers, thereby enhancing nursing quality and reducing patient rehospitalization rates.

Objective To construct a Nomogram prediction model based on body position exercise training for patients with chronic constipation. Methods A total of 327 patients with chronic constipation from March 2021 to March 2023 were divided into qualified group (n=279) and unqualified group (n=48) according to their performance in body position exercises. General clinical materials of the patients were collected, and univariate and multivariate Logistic regression analyses were performed to identify risk factors for unqualified body position exercises in patients with chronic constipation; the R software was used to construct a Nomogram model for predicting unqualified body position exercises in patients with chronic constipation, and the receiver operating characteristic (ROC) curve and calibration curve were applied to verify the discrimination and consistency of the Nomogram model. Results There were no significant differences in gender, education level, history of smoking, history of alcohol abuse, history of hypertension, history of abdominal surgery, history of colonoscopy, and correct medication administration ratio between the two groups (P>0.05); the unqualified group had higher age, longer duration of chronic constipation, and a higher proportion of diabetes history compared to the qualified group (P < 0.05); age, duration of chronic constipation, and diabetes history were independent risk factors for unqualified body position exercises in patients with chronic constipation (P < 0.05). The constructed Nomogram prediction model demonstrated excellent discrimination (area under the curve was 0.923, 95%CI, 0.888 to 0.949, with sensitivity and specificity of 87.50% and 81.00% respectively) and consistency (H-L goodness-of-fit test χ²=2.246, P=0.973). The clinical value of this Nomogram model in predicting unqualified body position exercises for patients with chronic constipation was high when the high-risk threshold probability ranged from 0.06 to 0.80. Conclusion Age, duration of chronic constipation, and diabetes history are independent risk factors for unqualified body position exercises in patients with chronic constipation, and the Nomogram model constructed based on these multi-factor results has high discrimination and consistency in predicting unqualified body position exercises for patients with chronic constipation.

【Objective】 To explore the effect of inspection sheet on improving the quality of apheresis platelet, the satisfaction of blood donors and the cooperation ability of phlebotomists in the process of apheresis platelet collection. 【Methods】 Apheresis platelet donors from May to August 2021 in our center were selected as control group(without inspection sheet) and those from September to December 2021 were included in the observation group (with inspection sheet). The incidence of abnormal collection and the causes during collection process were compared between the two groups.And 100 first-time blood donors in each group were randomly selected for satisfaction survey. The questionnaire was made to investigate the phlebotomists’ recognition on the implementation of inspection sheet. 【Results】 The number of blood donors in the two groups were 6 673 and 6 559, with 111 and 49 abnormal cases, respectively. The total incidence of abnormal cases during blood collection before and after the implementation of inspection sheet was 1.66% and 0.75%, respectively, with the latter significantly lower than the former(P<0.001). The most common causes of abnormal conditions were repetitive puncture, followed by adverse reaction of blood donation, red blood cells contamination in platelet and fatty blood. The satisfaction of first-time blood donors was higher than before the implementation, and the recognition of phlebotomists on the inspection sheet was more than 90%. 【Conclusion】 The implementation of inspection sheet helps to regulate the collection process, strengthen the responsibility and service consciousness of phlebotomists, improve the satisfaction of blood donors, reduce the incidence of adverse events, and improve the quality of platelet products, which is worth popularizing in blood collection and supply institutions.

【Objective】 To investigate the effects of echinacoside （ECH） on mitochondrial biosynthesis and cardiomyocytes’ apoptosis in heart failure （HF） and to explore its related mechanisms. 【Methods】 The experimental animals were divided into three groups： the rat model of HF （HF） was induced by intraperitoneal injection of ISO， and pre-treated with ECH by intraperitoneal injection （ECH） and nomal control （ctrl group）. Cardiac function was detected by echocardiography after 2 weeks of treatment. The ultrastructure of myocardium was observed by transmission electron microscopy and the mitochondrial density and vacuolation rate were analyzed. The expressions of apoptosis-associated proteins were evaluated by Western blotting， and genes related to mitochondrial biosynthesis were examined by Real-time PCR. 【Results】 ECH increased 1eft ventricular ejection fraction （LVEF） and 1eft ventricular fraction shortening （LVFS）， but decreased 1eft ventricular end-systolic diameter （LVEDs） and 1eft ventrieular end-diastolic diameter （LVEDd） when compared to HF group （P<0.01） and improved cardiac function. The myocardial ultrastructure was significantly improved by ECH， the density of regular shapes of mitochondria was increased， and the percentage of vacuolated rate was reduced by ECH （P<0.01）. The expression of anti-apoptotic protein Bcl-2 was upregulated and that of pro-apoptotic protein Bax was downregulated in ECH group. The mRNA of mitochondrial biosynthesis related genes PGC-1， NFR-1， NFR-2 and TFAM was significantly upregulated in ECH group. 【Conclusion】 ECH promotes mitochondrial biosynthesis and inhibits cardiomyocytes’ apoptosis by up-regulating PGC-1/NFR signaling pathway， thus improving cardiac function.

Objective: To analyze the occurrence and epidemiological characteristics of acute poisoning caused by Coriaria sinica maxdim in Guizhou Province during 2015 to 2020, and to provide scientific basis for prevention of Coriaria sinica maxim poisoning. Methods: A total of 176 cases of Coriaria sinica maxim poisoning were reported in Guizhou Province during 2015 to 2020, with all of the 505 affected were children and adolescents under 16 years old. No death was reported. Poisoning caused by Coriaria sinica maxim was most commonly reported in the year of 2020, with 97 reported incidents and 292 poisonings. Poisoning incidents were most freqently reported in the mature stage of Coriariasinica fruit during April to June, with 153 cases and 437 poisoning cases reported in May. The top three areas reporting Coriaria sinica maxim poisoning included Bijie, Anshun and Zunyi City, with the number of reported eventws being 57, 27, and 27, and poisoned children and adolescents of 160, 90, and 73. Most of the affected children were from rural areas. The median incubation period was 2 hours, and the primary clinical symptoms included vomiting( 93.66 %), nausea(58.02%) and abdominal pain(38.42%). Conclusion A large number of Coriaria sinica maxim poisoning incidents occur due to unsupervised access to Coriaria sinica maxim among rural children. The publicity and education of children, especially for rural left behind children, should be strengthened to reduce the incidence of Coriaria sinica maxim poisoning.

Objective: To describe and statistically analyze the monitoring results of foodborne disease outbreaks in children aged 0-6 years in Guizhou Province from 2011 to 2021, and to provide support for the prevention and control of foodborne diseases in children in the future. Methods: The epidemiological characteristics of foodborne disease outbreaks in children aged 0-6 years in the monitoring system from 2011 to 2021 were analyzed. Chi square test analysis was performed with the incidence rate as the dependent variable and the pathogenic factors, residence and other factors as independent variables. Results: A total of 618 foodborne disease outbreaks were reported in children aged 0-6 years, accounting for 21.29% of the total foodborne disease outbreaks reported. There were 1 169 cases, 833 hospitalizations and 18 deaths, with a mortality rate of 1.54%. The reported incidents were concentrated in summer and autumn, with a peak of 159 reported incidents in May; the largest number of incidents was reported in Zunyi and Tongren, with 169 and 98 incidents respectively. Mainly rural families misuse caused by food borne diseases; poisonous mushrooms and their toxins, poisonous plants and their toxins and unknown causes are the main pathogenic factor ; there were significant differences in the incidence among different years, places of residence and pathogenic factors ( χ 2=3 444.44, 577.82, 1 935.15 , P <0.05). Conclusion The foodborne disease outbreaks in children aged 0-6 years account for a large proportion in the total foodborne disease outbreaks in Guizhou Province, and the mortality rate is high. It is necessary to strengthen the prevention and control of foodborne diseases in children, and rural families are the focus of prevention and control.

Objective: To describe the current reporting of pneumonia of unknown etiology (PUE) and factors that affect reporting by clinicians in China using the PUE surveillance system in order to provide a reference for improving PUE reporting rates in the future. Methods: Clinicians were recruited via the Sojump platform and requested to complete an anonymous self-administered questionnaire. Multivariate logistic regression analysis was used to assess factors influencing clinicians' reporting activities. Results: This study showed a low PUE case reporting rate and a poor understanding of PUE reporting among the investigated clinicians. Of the 136 clinicians who had diagnosed PUE cases, multivariate logistic regression analysis results showed that clinicians who had attended in-hospital training were more likely to report PUE than those who had not (OR 4.48, 95% CI 1.49-13.46). Clinicians with an expert panel on PUE in their hospital were more likely to report PUE cases than those without (OR 5.46, 95% CI 1.85-16.11). Conclusions: There is a need to promote and reinforce PUE surveillance system training among medical staff. In addition, PUE testing technologies in hospital laboratories should be upgraded, especially in primary and unclassified hospitals, to increase surveillance efficiency and improve PUE reporting rates.

Objective: To understand the epidemiological and spatial distribution characteristics of mushroom poisoning events in Zunyi, and to provide theoretical basis for the prevention of mushroom poisoning at the grassroots level. Methods: Descriptive analysis and spatial distribution of mushroom poisoning events reported by foodborne disease surveillance system in Zunyi were carried out. Results: A total of 525 cases of mushroom poisoning events were reported in Zunyi in the past ten years, with a total of 1 758 cases poisoning casesand 29 deaths. The occurrence of mushroom poisoning had seasonal fluctuation, mainly from June to October, accounting for 89.90% of the total. Family was the main place of mushroom poisoning, accounting for 96% of the total. Autochthonous gathering was the main source of mushroom poisoning events. Conclusion Mushroom poisoning is one of the main causes of food poisoning death. With the help of geographic information system(GIS), the distribution map of toadstools is preliminarily explored by combining environmental factors with the distribution of mushroom types.

Objective:To understand the current situation of nurses in 52 hospitals in China on mastery of knowledge about skin injury in the elderly based on the background of mixed-mode homogenization training.Methods:Using the convenient sampling method, a total of 1 067 nurses from 52 hospitals in China were selected as the research objects in January 2021. A self-designed questionnaire on knowledge of skin injury in the elderly was used to investigate the nurses through the questionnaire star and univariate analysis was used to analyze the influencing factors. A total of 1 067 questionnaires were distributed and 1 067 valid questionnaires were recovered, and the effective recovery rate was 100%.Results:The knowledge scores of pressure injury, incontinence-associated dermatitis, skin tear and xerosis cutis among 1067 nurses were (95.66±7.37) , (95.65±9.15) , (91.37±15.45) and (87.67±15.91) , respectively. The results of univariate analysis showed that hospital grade was the influencing factor of nurses' knowledge score of pressure injury, skin tear and incontinence-associated dermatitis ( P<0.05) , educational background was the influencing factor of nurses' knowledge score of skin tear ( P<0.05) , professional title was the influencing factor of nurses' knowledge scores of pressure injury, incontinence-associated dermatitis and xerosis cutis ( P<0.05) . Conclusions:Hospitals at all levels need to strengthen the theoretical and practical knowledge training for nurses on skin xerosis and skin tear in the elderly, especially for nurses with primary titles and lower education in grassroots hospitals.
