Objective:To summarize the clinical features of primary segmental volvulus (PSV) in neonates.Methods:A retrospective analysis was conducted on the clinical data of neonates with PSV who were admitted to the Department of Neonatal Surgery, Children's Hospital Affiliated to Capital Institute of Pediatrics from May 2014 to May 2023. The clinical manifestations, auxiliary examinations, treatment and prognosis of the neonates were summarized, and descriptive statistical analysis was performed on the collected data.Results:A total of 10 neonates with PSV were included, with a mean gestational age of (34.1±3.0) weeks and birth weight of (2 291±646) g. Eight cases had an onset age of 3 d or less, and 2 cases had an onset age of more than 3 d. Abdominal distension was observed as the main manifestation in all cases, while bilious vomiting occurred in seven cases and hematochezia in five cases. Imaging examinations mainly revealed low intestinal obstruction without specific manifestations. Laboratory tests showed metabolic acidosis and varing degrees of anaemia. Nine cases underwent diagnostic abdominal puncture, of which five had bloody ascites, two had clear ascites, one had bloody mixed with fecal-like ascites, and one had chylous ascites. All the cases underwent emergency exploratory laparotomy and segmental small bowel resections with either primary intestinal anastomosis or enterostomy. All cases were successfully cured and had been followed up to the age of 4 months to 9 years with good growth and development as normal children of the same age.Conclusions:Neonatal PSV is an independent abdominal emergency characterized by non-specific clinical manifestations and difficult preoperative diagnosis, but the overall prognosis is favorable after active surgical treatment.

Objective·To investigate the intervention effect of oral motor training combined with pediatric tui-na on feeding intolerance in preterm infants to provide new treatment options and improve the quality of care.Methods·By using a non-simultaneous controlled clinical trial method,75 eligible preterm infants from the neonatal unit of a tertiary care hospital in Jinan were selected as the experimental group to implement oral training combined with pediatric massage therapy.Another 60 preterm infants admitted in 2020 were selected as the control group,who had already received oral motor training but had not received pediatric massage.The experimental group was treated for 7 d and the efficacy of the two groups was compared.Comparisons between the two groups included signs of feeding intolerance such as vomiting,gastric remnants and other outcome indicators such as first oral feeding time,gastric tube retention time,increased milk volume at day 3 and increased milk volume at day 7,feeding initiation time,increased weight at day 3 and increased weight at day 7,recovery time of birth weight,and days of hospitalization in both groups.Results·The differences in gender,age,birth weight,and Apgar score between the two groups before treatment were not statistically significant(P>0.05)indicating comparability.After treatment,preterm infants in the experimental group showed significant improvement in feeding performance,first oral feeding time,gastric tube retention time,increased milk volume at day 3 and increased milk volume at day 7,increased weight at day 3 and increased weight at day 7,hospitalization days and other observed indexes compared with the control group,and the differences were statistically significant(P<0.05).There was no significant difference in the feeding initiation time and recovery time of birth weight between the two groups(P>0.05).Conclusion·The combined application of oral motor training and pediatric tui-na is significantly more effective than single oral motor training in the short-term treatment of feeding intolerance in preterm infants.This combination therapy helps preterm infants to increase milk intake and accelerate weight gain,helps the children to recover intestinal function,establishes early nutritional support,promotes growth and development,and reduces the risk of long-term complications.This treatment is simple,safe and efficient,and has the value of popularization.

"Flipped Classroom" is a new kind of "student-centered" teaching model, which can give full play to the advantages of both sides of teaching and learning. According to this teaching model, we redesigned the teaching process, in which the students studied by themselves and built their own knowledge system. Moreover, each of them took part in three stages of experimental design including digital signal collection, analysis and processing in groups. Results have shown that this model can fully stimulate students' learning interest, not only helps students to deepen understanding of digital signal processing theory knowledge, but also strengthen the ability of autonomous learning and team collaboration. The teaching model maybe have certain reference function in comprehensive experiment teaching of Digital Signal Processing course for biomedical engineering specialty.

Based on the summary and reflection of the existing course construction content, this paper redesigns the course teaching to Brain Functional Imaging and forms a new curriculum construction scheme, including improving the professional teachers' ability of the teaching team by means of "internal training" + "external introduction", building an online and offline integrated teaching mode by combining online teaching resources such as course website with offline teaching (such as literature guidance, classroom discussion, comprehensive experimental design, etc.), and designing comprehensive experiments related to Electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS), which is driven by scientific research projects, based on the scientific research experimental platform of the teaching and research department. This construction scheme is of great significance for improving the teaching quality of the course, stimulating the learning interest of graduate students, and cultivating the comprehensive application and practical innovation ability of graduate students' brain imaging technology. And it also provides the reference for the further construction of the course and teaching reform in the future.

This paper reviews the pathogenesis, assessment tools, influencing factors and interventions of diabetes patients with frailty at home and abroad. This paper also puts forward suggestions such as focusing on diabetes combined with frailty, taking frailty assessment as the routine assessment of diabetes patient, preparing frailty assessment tools for diabetes patients in China, and carrying out prospective investigation research, so as to provide a reference basis for early identification of frailty and formulation of individual interventions.

Objective:To construct a Question Prompt List of information needs for patients with interstitial lung disease, providing a tool for patients with interstitial lung disease to actively obtain disease-related information.Methods:A literature study was conducted based on the three core needs (ERG) theory framework of existence,relatedness and growth. A purposive sampling method was used to select 15 patients with interstitial lung disease from Drum Tower Hospital, Medical School of Nanjing University from December 2021 to January 2022 for descriptive research. Based on literature research and qualitative research, the initial items of the Question Prompt List were determined through expert inquiry, and the items were extracted, discussed, and adjusted, and finalized the list of information needs and prompts for patients with interstitial lung disease.Results:The 19 experts participated in the consultation, with a positive coefficient of 100.0% and 94.7% for two rounds of consultation, an authoritative coefficient of 0.91 and 0.92, and the Kendall coordination coefficient of 0.31 and 0.23, respectively. Finally, a list of interstitial lung disease patients′ question prompts containing 4 primary indicators and 34 secondary indicators was formed.Conclusions:Based on the ERG theory, the research method for the Question Prompt List of information needs for patients with interstitial lung disease is scientific and reliable, and can be used in clinical practice to help patients inquire and obtain the necessary information.

Hypertensive disorder of pregnancy (HDP) involves two major public health issues: mother-infant safety and prevention and controlling major chronic disease. HDP poses a serious threat to maternal and neonatal safety, and it is one of the leading causes of maternal and perinatal morbidity and mortality worldwide, as well as an important risk factor for long-term cardiovascular disease (CVD). In order to explore effective strategies to prevent and control the source of CVD and reduce its risk, we have established a cohort of HDPs in Shenzhen for the primordial prevention of CVD. The construction of the HDP cohort has already achieved preliminary progress till now. A total of 2 239 HDP women have been recruited in the HDP cohort. We have established a cohort data management platform and Biobank. The follow-up and assessment of postpartum cardiovascular metabolic risk in this cohort has also been launched. Our efforts will help explore the pathophysiological mechanism of HDP, especially the pathogenesis and precision phenotyping, prediction, and prevention of pre-eclampsia, which, therefore, may reduce the risk of adverse pregnancy outcomes, and provide a bridge to linking HDP and maternal-neonatal cardiovascular, metabolic risk to promote the cardiovascular health of mothers and their infants.

The status of lymph node metastasis is an important prognostic factor for many malignant tumors, including lung cancer. In the 8th edition of the TNM staging system for lung cancer, the T staging had obvious changes and refinements, but the N staging had little changes. Recently, several studies have found that the prognosis of patients with the same N stage can vary greatly, suggesting that a more detailed subgroup of patients with the same N stage should be subdivided, including the inclusion of extra-capsular lymph node metastases (ENE). In this review, we reviewed the definition, classification/grading, imaging diagnosis, pathological diagnosis, related molecular markers and their relationship with the prognosis of lung cancer patients.

A male patient aged 1 year and 8 months with type 2 spondyloepimetaphyseal dysplasia with joint laxity (SEMDJL2) was reported. The clinical characteristics included short stature, flat middle face, hypotonia, limb joint relaxation, hyperextension of metacarpophalangeal articulation, etc. In addition, the patient had a history of congenital laryngeal stridor. Thus, SEMDJL2 was determined according to the above symptoms and medical history. Sanger sequencing showed that the child carried a c.443C>T missense mutation in the KIF22 gene, which resulted in an amino acid variation namely p.Pro148Leu. This phenotype was preliminarily determined as a pathogenic mutation. Therefore, it is suggested that next-generation sequencing genetic testing could be helpful for genetic diagnosis in children with congenital laryngeal stridor, systemic joint relaxation, and excessive joint extension.
