Objective To Screen out incidence of vitamin K deficiecy and complicated with hemorrhage in newborn patients, infant patients and normal neonates, and also study on the treatment of vitamin K deficiency. Methods Using emzymoimmunoelectrophoresis to test PIVKA Ⅱ in umbilical and vein blood. Results The incidence of vitamin K deficiency in normal neonates, newborn patients (≤ 5 days) and infants patients (25~60 days) are 31.2%,47.6% and 31.8%. The incidence of hemorrhage in newborn patients (≤5 days) is 26.0%, infant patients (25~60 days) is 66.6%. Intramuscular injection of vitamin K 1 1 mg is the proper dosage to prevent and treat vitamin K deficiency. Conclusion The neonates right after birth or about 25 days after birth, especially those of breast feeding and who are getting lievr and gall diseases should receive vitamin K 1 to prevent vitamin K deficiency.

Objective:To develop the Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with Inflammatory Bowel Disease (IBD), and test its reliability and validity.Methods:Guided by the theory of knowledge, attitude, and practice, a preliminary draft of the scale was formed through literature review, Delphi expert consultation, and pre-survey. From May to August 2022, convenience sampling was used to select 200 IBD patients who visited the Gastroenterology Clinic of three ClassⅢ Grade A comprehensive hospitals in Jiangsu Province as the research subject for a questionnaire survey. The critical ratio method, correlation analysis method, internal consistency method, commonality and factor loadings were used for item analysis of the scale. Exploratory factor analysis, content validity index, and internal consistency reliability were applied to test the reliability and validity of the scale.Results:A total of 200 questionnaires were distributed, and 181 valid questionnaires were collected, with an effective response rate of 90.50% (181/200). The Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with IBD included three dimensions of knowledge, attitude and practice, with a total of 21 items. The content validity index at the scale level was 0.917, and the content validity index at the item level ranged from 0.833 to 1.000. Exploratory factor analysis extracted three common factors, with a cumulative variance contribution rate of 74.197%. The Cronbach's α coefficient of the total scale was 0.951, and the coefficients of each dimension were 0.914 to 0.942. The test-retest reliability coefficient of the total scale was 0.918, and the test-retest reliability coefficients of each dimension ranged from 0.737 to 0.833.Conclusions:The Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with IBD has good reliability and validity, which can help medical and nursing staff evaluate patients' understanding and acceptance of microbial transplantation, so as to provide a basis for personalized communication in shared decision making between doctors and patients.
