Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

To analyze the positivity rate and titer of antinuclear antibody (ANA), as well as nuclear pattern and target antigen of ANA in healthy pregnant women during early pregnancy in Qingdao area. A prospective cohort study design was used to include a total of 9 528 healthy pregnant women registered at the Women and Children′s Hospital Affiliated to Qingdao University from March 2023 to June 2024.Indirect immunofluorescence assay (IIF) was used to detect ANA, its titer and cell staining pattern. Fifteen specific antibodies were tested using the magnetic bar code immunofluorescent luminescence method. Logistic regression model was used to analyze the risk factors of pregnancy with autoimmune disease(AID). The results showed that among 9 528 pregnant women in early pregnancy, 1 346 cases (14.1%) were positive of ANA, including 1 011 cases with a titer of 1∶100 (10.6%), 236 cases (2.5%) with a titer of 1∶320, and 99 cases (1.0%) were detected at a titer >1∶320. Among the 1 346 ANA-positive pregnant women, nuclear granular type accounted for the highest proportion (483 cases, 35.9%), followed by speckled type (347 cases, 25.8%) and cytoplasmic type (176 cases, 13.1%).Then, pregnant women with ANA titers ≥1∶100 were detected 15 specific antibodies.Anti-SSA was tested in 121 cases accounted for the majority, followed by 110 cases with anti-Ro-52, 56 cases with anti-SSB, 51 cases with anti-mitochondrial M2 subtype antibodies and 37 cases with anti-centromere B. In conclusion,in healthy pregnant women in Qingdao area, ANA positivity rate was 14.1%, and the titer of ANA was mainly at 1∶100.The predominant nuclear patterns were nuclear granular and speckled types.The specific autoantibodies were mainly anti-SSA antibodies and anti-Ro-52 antibodies.The detection of ANA and specific autoantibodies is of great significance for early prediction, diagnosis, and intervention of autoimmune diseases during pregnancy.

Objective:To analyze food intolerance status in children in Qingdao by detecting the serum levels of food-specific IgG (sIgG).Methods:In this cross-sectional study, a total of 4 249 children aged 0 to 14 years (all were permanent residents of Qingdao City) admitted to Women and Children′s Hospital Affiliated to Qingdao University from May 2017 to December 2020 for suspected food intolerance were selected as the study objects with the whole sampling method. According to the age, the objects were divided into 4 groups: 0-<1 year group (440 cases), 1-<3 years group (1 761 cases), 3-<6 years group (1 193 cases), and ≥6 years group (855 cases). Positive condition of serum sIgG antibodies of 14 kinds of food in the children were detected by enzyme-linked immunosorbent assay. Chi-square test was used to compare the positive rate of the antibodies among different foods, gender and age groups.Results:The total positive rate of food sIgG antibody in 4 249 children was 95.32% (4 050/4 249), the highest positive rate was found in eggs (81.50%) and the lowest positive rate was found in pork (1.15%). The positive rates of sIgG antibody in milk (54.98% vs 49.69%, χ2=11.627), crab (5.59% vs 3.71%, χ2=8.049) and shrimp (4.62% vs 2.75%, χ2=9.784) in boys were significantly higher than those in girls, and the positive rates of sIgG antibody in tomato (49.19% vs 45.54%, χ2=5.510), cod (8.53% vs 5.96%, χ2=10.512) and beef (2.58% vs 1.70%, χ2=3.959) in girls were significantly higher than those in boys (all P<0.05). The total positive rate of sIgG antibody in 14 foods was the lowest in 0-<1 year group (89.09%), and it was the highest in 3-<6 years group (96.98%) ( χ2=63.950, P<0.001). The highest positive rate in 0-<1 year group was found in tomato (56.36%), and it was eggs (85.29%, 88.94%, 85.50%) in all the other 3 groups. The positive rates of corn and beef decreased with age ( χ2=44.098, 20.106, P<0.001), while those of cod and mushroom increased with age ( χ2=32.315, 40.338, P<0.001). The positive rate of wheat (57.13%, χ2=42.273), tomato (57.01%, χ2=209.862), soybean (24.99%, χ2=92.580), crab (6.81%, χ2=33.201), shrimp (6.25%, χ2=47.863) were all the highest in 1-<3 years group among the 4 groups (all P<0.001), and the positive rate of chicken was the highest in 3-<6 years group (7.88%, χ2=29.875; P<0.001). Conclusions:Children in Qingdao have a high level of food intolerance, and the highest positive rate is for eggs. Milk, crab and shrimp should be focused on for boys, while tomatoes, cod and beef shoud be paid more attention to for girls. Children of different ages have different kinds of food intolerance, and their diets should be adjusted reasonably according to the characteristics.

Objective:To investigate the efficacy and safety of prolonged dual antiplatelet therapy (DAPT) (aspirin + clopidogrel) after coronary artery bypass grafting (CABG) for more than 12 months.Methods:1 900 patients who received CABG treatment in Tianjin Chest Hospital from January 2019 to October 2020 were continuously included, and 1 528 patients were finally identified according to the inclusion and exclusion criteria. According to whether the patients continued to take DAPT treatment 12 months after discharge, they were divided into the extended DAPT group and the standard DAPT group. Cox multivariate regression and propensity score matching (PSM) analysis were performed on major cardiovascular and cerebrovascular adverse events (MACCE) and clinically related bleeding events in the two groups during 12-24 months after discharge to evaluate the efficacy and safety of extended DAPT treatment for more than 12 months. Results:Of the 1 528 patients, 624 (40.8%) continued to take DAPT 12 months after discharge. Compared with patients receiving standard DAPT, patients receiving extended DAPT had a lower incidence of MACCE within 12 to 24 months ( HR=0.597, 95% CI: 0.399-0.892, P=0.012); ( HR=0.519, 95% CI: 0.338-0.798, P=0.003), and there was no significant increase in clinically relevant bleeding risk ( HR=1.209, 95% CI: 0.522-2.798, P=0.658), ( HR=1.112, 95% CI: 0.452-2.737, P=0.817). At the same time, prolonged DAPT treatment also brought a good net benefit. Conclusion:Prolonged DAPT treatment after CABG for more than 12 months significantly reduced the risk of ischemia at 12-24 months after surgery, and did not significantly increase the risk of bleeding at 12-24 months after surgery. It may be beneficial for patients treated with CABG to continue DAPT (aspirin+ clopidogrel) on the basis of intensive DAPT therapy for 1 year.

Objective:To explore the status quo of nurses' nursing informatics competency and its relationship with perceived professional benefits and intention to stay, so as to provide a basis for improving nurses' nursing informatics competency and reducing nurses' turnover.Methods:Using the convenient sampling method, nurses from 7 hospitals in Shandong Province were selected as the research objects from June 2020 to June 2021. The survey was conducted using General Information Questionnaire, Self-assessment of Nursing Informatics Competencies Scale (SANICS) , Questionnaire of Nurses' Perceived Professional Benefits and Questionnaire of Nurses' Intention to Renain. A total of 900 questionnaires were distributed in this study and 880 valid questionnaires were recovered, with an effective rate of 97.8%.Results:For 880 nurses, the scores of SANICS, Questionnaire of Nurses' Perceived Professional Benefits Scale and Questionnaire of Nurses' Intention to Renain were respectively (85.54±12.43) , (132.21±19.56) and (22.68±3.84) . The structural variance model showed that the nursing informatics competency of nurses could directly affect the intention to stay (effect value 0.456) , and the nursing informatics competency could also have an indirect effect on the intention to stay through perceived professional benefits of nurses (effect value 0.067) , with a total effect value 0.523.Conclusions:The nursing informatics competency of nurses is at the medium level. By improving the nursing informatics competency, the self-development of nurses can be promoted and their perceived professional benefits can be improved, so as to increase the intention to stay and reduce the turnover of nurses.

Objective:To explore the effectiveness of clinical pathway (CP) and team-based learning (TBL) teaching method in standardized residency training of gynecology.Methods:The research included 40 residents as objects who took standardized training in gynecological rotation in Luohe Central Hospital from July 2017 to July 2019, and they were randomized into experimental group and control group. The combination of CP and TBL teaching method was used in the experimental group ( n=20), while the traditional teaching method was applied in the control group ( n=20). All residents were tested for the professional theory and clinical skill after training. After the training, a survey about the teaching satisfaction and the effectiveness of teaching methods was conducted for both groups. Statistical analysis was performed by SPSS 23.0 software. Results:The average scores of professional theory and clinical practice skills in the experimental group were (85.55±5.96) points and (89.90±6.40) points respectively, which were better than the average scores of the control group [(76.36±6.68) points and (75.50±4.81) points, respectively], and there were significant differences between two groups ( P<0.05). The results of the questionnaire survey showed that the experimental group residents had a higher degree of satisfaction and a higher evaluation of the teaching method than the control group. Conclusion:CP and TBL teaching is beneficial to improve the quality of standardized residency training of gynecology, and it is suggested to make wide popularization and application in the training.

Four hundred and four male patients with primary gout were enrolled. According to the degree of nonalcoholic fatty liver diseases (NAFLD), the patients were divided into simple gout ( n=121), gout combined with mild NAFLD ( n=149) and gout combined with moderate-severe NAFLD ( n=134). The height, weight, waist, hip, blood pressure and blood biochemistry parameters of patients were measured. The degree of NAFLD was negatively correlated with the age of patients in three groups. The BMI, ratio of waist/hip, count of red cells, hemoglobin, hematocrit, red blood cell distribution width ( SD and CV), triglyceride, alanine aminotransferase and HOMA-IR were increased with the increasing of NAFLD severity (all P<0.05). Red blood cell count, hemoglobin, alanine aminotransferase, serum uric acid increased with the increasing of NAFLD severity (all P<0.05). Platelet, serum urea nitrogen and serum creatinine were decreased with the increase of NAFLD severity. Logistic regression showed that BMI, hemoglobin and HOMA-IR were independent risk factors for NAFLD. The prevalence and the severity of NAFLD was increased with increasing quadrates of hemoglobin. Taking group Q1 as a control, OR of NAFLD in group Q2 was 1.166(95 %CI:0.638-2.133), OR in group Q3 was 2.011(95 %CI:1.122-3.605)and OR in group Q4 was 3.120(95 %CI:1.613-6.034). The result indicates that hemoglobin levels are associated with the development and the severity of NAFLD in male patients with primary gout.

Objective:To explores the effect of micro-class health education combined with relaxation-induced exercise on negative emotion and sleep quality of patients with lumbar disc herniation after operation.Methods:A total of 60 patients with lumbar disc herniation who were admitted and treated in Anhui No.2 Provincial People's Hospital from January 2018 to August 2019 were selected as research objects. According to the random number table method, they were divide divided into the experimental group (30 cases) and the and the conventional group (30 cases) . Patients in the conventional group were given routine nursing such as mental health education and nursing while patients in the experimental group were given micro-class health education combined with relaxation-induced exercise therapy on basis of routine nursing. Anxiety and depression levels, sleep status and satisfaction of patients were compared between the two groups.Results:The anxiety and depression scores in the experimental group after nursing were lower than those in the conventional group, and the differences were statistically significant ( P<0.05) . The sleep time, sleep efficiency and score of sleep quality in the experimental group were better than those in the conventional group, and the differences were statistically significant ( P<0.05) . The total satisfaction of nursing in the experimental group was higher than that in the conventional group, and the difference was statistically significant ( P<0.05) . Conclusions:On the basis of micro-class health education, assisted relaxation-induced exercise can improve the negative emotions of patients with lumbar disc herniation after operation and improve the sleep status of patients, which is conducive to postoperative rehabilitation of patients.
