The expert authority coefficients were 0.895 and 0.870, respectively. The Kendall harmony coefficients of the whole index were 0.134 and 0.178 (both P<0.01), respectively. The final evaluation index system of neonatal breastfeeding nursing quality under the state of mother-infant separation includes 3 first-level indicators, 18 second-level indicators and 82 third-level indicators. Conclusions:The evaluation index system of neonatal breastfeeding nursing quality in the state of mother-infant separation established in this study is highly scientific and reliable, highlighting the characteristics of neonatal breastfeeding nursing work in the state of mother-infant separation, and can provide a reference for the evaluation of neonatal breastfeeding nursing quality in the state of mother-infant separation.

The cold congeal and blood stasis syndrome is a common clinical traditional Chinese medicine（TCM） syndrome. The animal model of cold ongeal and blood stasis syndrome is the basis for exploring the essence of TCM cold congeal and blood stasis syndrome，and the premise of follow-up TCM clinical research.This paper summarized the preparation method， theoretical support，and evaluation method of animal models of cold congeal and blood stasis syndrome in recent years and analysed the strengthens and weaknesses of different models. At present，the common animal models of cold congeal and blood stasis syndrome mainly include etiological model，etiological and pathological composite model and disease-syndrome combination model. The etiological model was mainly prepared by cold exposure，which could be divided into whole-body freezing， ice bath and local frostbite. The etiological and pathological composite model was mainly prepared by cold stimulation combined with epinephrine injection. The common disease-syndrome combination models included the coronary heart disease model of cold congeal and blood stasis syndrome，primary dysmenorrhea model of cold congeal and blood stasis syndrome，endometriosis model of cold congeal and blood stasis syndrome， and arteriosclerosis obliterans model of cold congeal and blood stasis syndrome. The three models have both advantages and disadvantages. Specifically， the disease-syndrome combination model had the highest consistency with clinical practice and was more reliable and practical. However， the disease types of this model were specific，and the combination method of disease and syndrome was controversial. The evaluation indicators of the animal models of cold congeal and blood stasis syndrome focused on the characterization of the syndrome and the physico-chemical indicators related to blood flow，such as blood rheology，coagulation function and microcirculation. In addition， some scholars explored the evaluation indicators from the aspects of vasomotor function，endocrine and energy metabolism. The objectivity and specificity of the current model evaluation methods needed to be further improved. The research of animal model of cold congeal and blood stasis syndrome should be based on clinical practice and oriented by clinical demand. Only by establishing animal models that are highly consistent with the characteristics of clinical disease and syndrome can we better reveal the essence of cold congeal and blood stasis syndrome and promote the modernization of TCM.

Objective:To explore the independent risk factors of poor healing of surgical incisions in patients with drainage tube removal after thoracic and abdominal surgery and establish a risk prediction model for poor healing of surgical incisions.Methods:Using the convenient sampling method, a total of 545 patients who underwent thoracic and abdominal surgery in the Affiliated Hospital of Qingdao University were selected from July to December 2020. The patients were divided into the poor wound healing group ( n=87) and the non-incision poor healing group ( n=458) according to whether they had poor wound healing. Logistic regression analysis was used to analyze the risk factors of poor healing of surgical incisions and build a risk prediction model. The receiver operating characteristic (ROC) area under the curve was used to test the model to predict the effect and 230 patients were selected to verify the model prediction effect. Results:In this study, 5 factors including duration of exudation, serum albumin, incision infection, the volume of exudation during catheterization and catheterization time were finally included to construct a risk prediction model. The model formula was Z=4.608+4.855× duration of exudation +3.173× serum albumin +3.739× infection of the incision +2.271×the volume of exudation during catheterization + 0.466× catheterization time. The area under ROC curve of this model was 0.773 (95% CI: 0.678 - 0.868). The maximum value of Youden index was 0.549, the sensitivity was 0.742 and the specificity was 0.807. Conclusions:The risk prediction model of poor incision healing after drainage tube removal for patients undergoing thoracic and abdominal surgery can better predict the risk of poor incision healing and provide a basis for clinical medical staff to take preventive management measures for high-risk patients in time.

Objective:To investigate the neonatal outcomes and prognosis of fetuses who were prenatally diagnosed with intraventricular hemorrhage(IVH) to provide evidence for clinical consultation and management.Methods:Clinical data of fetal IVH cases ( n=89) diagnosed by fetal neurosonogram (NSG) in Peking University First Hospital from January 2012 to April 2020 were retrospectively collected, and neonatal outcomes were analyzed, involving fetuses with different grades of IVH and coexisting abnormalities. These patients were followed up for more than three months after birth. Two child development screening systems, Ages & Stages Questionnaires (Third Edition) (ASQ-3) and Ages & Stages Questionnaires: Social-Emotional (ASQ-SE), were used to assess the development of the patients from several aspects including physical growth, oral communication, motor ability and social emotions. Descriptive statistical analysis was used in this study. Results:(1) A total of 89 fetuses were enrolled and 66.3% (59/89) of them underwent fetal cranial MRI examination after ultrasound diagnosis. Among these 59 cases, 32(54.2%) had the same results with fetal NSG; 20(33.9%) with the diagnosis of remote ventricular cystic hemorrhage by fetal NSG, but misdiagnosed by MRI, were all confirmed by neonatal craniocerebral ultrasound; 7(11.9%) were lost to follow-up or terminated. In addition to IVH that was consistent with the ultrasound diagnosis, MRI also found three cases of cortical malformation, three cases of subdural hemorrhage and two cases of cerebral parenchymal hemorrhage. (2) Among the 89 cases, 37 (41.6%) underwent neonatal craniocerebral ultrasound examination after birth showing small amount of remote IVH, which was consistent with previous fetal NSG diagnosis. (3) There were 38 cases complicated by lateral ventricular widening (three lost to follow-up, 18 were terminated , one died in uterus, 15 with good and one with poor outcome), 10 cases by severe IVH sequelae (one lost to follow-up and nine were terminated) and 10 by craniocerebral malformation (one lost to follow-up, eight were terminated and one with poor neonatal prognosis). Two cases with extracranial malformation (ureteropelvic junction obstruction) were healthy after birth. (4) There were 29, 30, 16 and 14 cases of gradeⅠ,Ⅱ,Ⅲ andⅣ of fetal IVH, respectively. Among all cases, 12 were lost to follow-up; three died in uterus (all with gradeⅣ IVH); 31 were terminated and 43 were born and followed up. During the follow-up of the 43 cases, two (one grade Ⅰ case with corpus callosum dysplasia and one grade Ⅲ case with fetal cytomegalovirus infection) had poor prognosis, while the other 41 (one gradeⅢ, 17 gradeⅡ and 23 gradeⅠcases) showed no severe abnormalities.Conclusions:Fetal NSG is the first choice in screening fetal IVH and MRI can be a valuable aid. The neonatal prognosis may be associated with the grade of hemorrhage and coexisting abnormalities. Fetuses with isolated grade Ⅰ or Ⅱ IVH usually have a relatively good prognosis.

Purpose: The purpose of the current study was to explore the functions and potential mechanism of miR-451a in breast cancer (BC). Methods: Quantitative reverse transcription real-time polymerase chain reaction was used to analyze the expression of miR-451a in human normal mammary cells (MCF-10A) and BC cells. Colony formation assay, terminal-deoxynucleoitidyl transferase mediated nick end labeling assay and transwell assays were conducted to validate the effect of miR-451a on proliferation, apoptosis, migration and invasion of BC cells, respectively. RNA pull-down, RNA immunoprecipitation and luciferase reporter assays were applied to investigate the upstream and downstream mechanisms of miR-451a in BC cells. Results: MiR-451a was expressed at a low level in BC cells. Overexpression of miR-451a repressed BC cells proliferation, migration and invasion. Moreover, long non-coding RNA AC092127.1 acted as a sponge of miR-451a to enhance the expression level of AE binding protein 2 (AEBP2) that was demonstrated to be the target gene of miR-451a in BC cells. Finally, rescue experiments validated that miR-451a and AEBP2 involved in AC092127.1-mediated BC cell growth, migration and invasion. Conclusion In a word, AC092127.1/miR-451a/AEBP2 axis contributes to BC cell growth, migration and invasion. Our results may help to find novel potential targets for BC treatment.

Objective:To explore the effect of pathway nursing under multidisciplinary collaboration on self-care ability and rehabilitation effect in patients with acute cerebral infarction.Methods:Using the convenient sampling method, a total of 294 patients with acute cerebral infarction who were admitted to the Department of Neurology in the Fengcheng Hospital, Fengxian District, Shanghai from January 2018 to December 2019 were selected as the research objects. A total of 147 patients with acute cerebral infarction admitted from January to December 2019 were included in the experimental group, while 147 patients with acute cerebral infarction admitted from January to December 2018 were included in the control group. The experimental group adopted pathway nursing under multidisciplinary collaboration, while the control group adopted neurology routine nursing. Scores of Exercise of Self-Care Agency (ESCA) , National Institutes of Health Stroke Scale (NIHSS) , Fugl-Meyer Assessment (FMA) , Barthel Index and nursing satisfaction of patients were compared between the two groups. Finally, 147 patients in the experimental group and 145 patients in the control group completed the experiment.Results:The scores of self-concept, self-responsibility, health knowledge level and self-care skills in ESCA of patients in the experimental group at discharge were respectively (25.36±4.86) , (20.43±3.21) , (53.37±5.89) and (40.02±3.78) and the nursing satisfaction score was (97.26±2.52) , which were higher than (21.48±4.33) , (16.24±3.25) , (46.44±5.47) , (30.08±3.81) and (90.65±3.16) in the control group, and the differences were statistically significant ( P<0.01) . The NIHSS score of the experimental group 60 days after discharge was (3.7±2.2) , lower than (6.9±2.3) of the control group. And FMA and Barthel Index scores were respectively (79.3±9.2) and (78.7±14.5) , higher than (65.6±8.4) and (60.3±16.6) of the control group, and the differences were statistically significant ( P<0.01) . Conclusions:The implementation of pathway nursing under multidisciplinary collaboration for patients with acute cerebral infarction can enhance the consciousness of self-management, contribute to the recovery of neurological function and limb motor function and improve the ability of self-care and nursing satisfaction of patients.

Objective:To investigate the current status of career success of ICU nurses and analyze its influencing factors.Methods:Using the convenient sampling method, a total of 178 ICU nurses from 7 Class Ⅲ Grade A hospitals in Guangzhou, Guangdong Province from April to May 2021 were selected as the research objects. General questionnaire and Chinese version of Career Success Scale were used to conduct the survey through the questionnaire network platform.Results:A total of 178 electronic questionnaires were filled in and 167 valid electronic questionnaires were recovered. The total score of career success of ICU nurses was (35.68±6.07). Multiple linear regression analysis showed that gender of ICU nurses, whether they had regular specialized skills training, and the cooperative relationship of doctors and nurses in departments were the influencing factors of career success scores of nurses ( P<0.05) . Conclusions:The career success level of ICU nurses needs to be improved. It is recommended that nursing managers should clarify the career development path of nurses, broaden the career development space of nurses and enhance their professional autonomy and work enthusiasm.
