To summarize the nursing care of a very low birth weight premature infant with severe type Ⅱbronchopulmonary dysplasia(BPD)during the transition period from hospitalization to home.The care of the infant was provided one-on-one by a BPD specialist nurse throughout the period.The key points of transitional care from hospitalization to home include:implementing tracheotomy and mechanical ventilation care to ensure stable blood oxygen saturation of the infant;providing nutritional support to improve the nutritional status of the infant;implementing step-by-step rehabilitation measures to improve the neuromotor development of the infant;implementing family integrated care to promote the primary caregivers of the infant to master nursing knowledge and skills;conducting personalized discharge follow-up with a multidisciplinary team to improve the quality of home care for this infant.After being hospitalized for 106 days,the infant was successfully discharged with a tracheotomy tube.At the age of 2 years and 6 months,a tracheotomy closure surgery was performed.After the surgery,the infant was able to breathe autonomously without symptoms of breathing difficulties and returned to normal family life.

Objective:To understand the current knowledge, attitude, and practice (KAP) on influenza and influenza vaccine among pregnant women in Suzhou and to analyze its influencing factors to provide technical support data for public health strategies for promoting influenza vaccination in pregnant women.Methods:A questionnaire was designed, and a stratified sampling method was used to conduct a face-to-face survey among pregnant women at different stages of pregnancy who received antenatal examinations at different levels of medical institutions in Suzhou, Jiangsu Province, in 2023. KAP status and influencing factors were analyzed by χ2 test and logistic regression analysis. Results:A total of 2 195 valid questionnaires were collected in this survey. The M( Q1, Q3) of knowledge about influenza and influenza vaccine among pregnant women in Suzhou was 7.60 (5.23, 9.80) points, and the score range was 0.20-14.71 points, the passing rate was 34.12%, the awareness rate of influenza vaccine was 57.45%, and the vaccination rate of influenza vaccine was 1.91% within one year before the survey. The willingness to receive influenza vaccine during pregnancy was only 3.57%. Multivariate analysis of influenza and influenza vaccine-related knowledge scores showed that the passing rate was positively correlated with education level and gestational age. In contrast, family income was negatively correlated with living in rural areas, working as migrant workers, and having no medical insurance. Multivariate analysis of vaccination intention showed that decreased effectiveness of influenza vaccine and increased adverse reactions decreased vaccination intention during pregnancy. Conclusions:The pregnant women in Suzhou pay more attention to influenza, and vaccination rates and intentions are generally low. Pregnant women with early and second trimester of pregnancy, low education, living in rural areas, working as migrant workers, and not purchasing medical insurance are the key groups to popularize the knowledge about influenza and influenza vaccine.

Objective:To analyze the clinical and imaging features of patients with COVID-19-related osmotic demyelination syndrome (ODS).Methods:COVID-19-related ODS cases diagnosed in the Department of Neurology, Peking Union Medical College Hospital from January 2020 to September 2023 were retrospectively reviewed. And their past medical history, possible triggers, clinical manifestations, imaging manifestations, treatment and prognosis were summarized.Results:A total of 5 patients with COVID-19-related ODS were included. Electrolyte disturbances acted as an inducement of ODS in all patients (5/5),4 of whom with hyponatremia. Four of 5 patients first presented with disturbance of consciousness, followed by predominant dystonia. Imaging of all patients (5/5) showed isolated extrapontine myelinolysis (EPM). With the prolongation of the course of disease, such signal intensity could return to normal, and lesions showed atrophic changes in some patients. The patients′ clinical symptoms were partly relieved within a few days to a few months after treatment.Conclusions:COVID-19-related ODS is mostly associated with hyponatremia, and EPM is more common. COVID-19 should be considered as a risk factor for ODS.

Objective:To explore the impacts of dexmedetomidine combined with dizosin on sciatic nerve-femoral nerve block and blood glucose in diabetes foot patients undergoing surgery.Methods:A total of 120 diabetes foot patients underwent surgery who were admitted to Second Hospital of Shanxi Medical University from Jul. 2020 to Aug. 2022 were selected as the research objects. The anesthesia method was sciatic nerve block-femoral nerve block, and were randomly grouped into the control group (60 cases) and the observation group (60 cases). The control group was treated with diazosin, while the observation group was treated with dexmedetomidine combined with diazosin. The effects of sciatic nerve block and femoral nerve block, and blood glucose level were compared between the two groups.Results:The VAS scores at T1, T2 and T3 in the two groups were obviously lower than those at T0, and the VAS scores in the observation group were obviously lower than those in the control group ( P<0.05). The onset time of motor nerve block and sensory nerve block in the observation group was obviously lower than that in the control group ( P<0.05). The maintenance time of motor nerve and sensory nerve in the observation group was obviously higher than that in the control group ( P<0.05). Compared with T0, systolic blood pressure, diastolic blood pressure and heart rate in T1, T2 and T3 time periods in the two groups were obviously lower, and the observation group were obviously lower than the control group ( P<0.05) ; The observation group had no significant difference compared with the control group in terms of the incidence of adverse reactions. Conclusion:Dexmedetomidine combined with dizosin can effectively relieve pain, improve nerve function block, and maintain the stability of hemodynamics in diabetes foot patients undergoing surgery.

BACKGROUND: Sjögren's syndrome (SS) is an autoimmune disorder characterized by sicca syndrome and/or systemic manifestations. The treatment is still challenging. This study aimed to explore the therapeutic role and mechanism of exosomes obtained from the supernatant of stem cells derived from human exfoliated deciduous teeth (SHED-exos) in sialadenitis caused by SS. METHODS: SHED-exos were administered to the submandibular glands (SMGs) of 14-week-old non-obese diabetic (NOD) mice, an animal model of the clinical phase of SS, by local injection or intraductal infusion. The saliva flow rate was measured after pilocarpine intraperitoneal injection in 21-week-old NOD mice. Protein expression was examined by western blot analysis. Exosomal microRNA (miRNAs) were identified by microarray analysis. Paracellular permeability was evaluated by transepithelial electrical resistance measurement. RESULTS: SHED-exos were injected into the SMG of NOD mice and increased saliva secretion. The injected SHED-exos were taken up by glandular epithelial cells, and further increased paracellular permeability mediated by zonula occluden-1 (ZO-1). A total of 180 exosomal miRNAs were identified from SHED-exos, and Kyoto Encyclopedia of Genes and Genomes analysis suggested that the phosphatidylinositol 3 kinase (PI3K)/protein kinase B (Akt) pathway might play an important role. SHED-exos treatment down-regulated phospho-Akt (p-Akt)/Akt, phospho-glycogen synthase kinase 3β (p-GSK-3β)/GSK-3β, and Slug expressions and up-regulated ZO-1 expression in SMGs and SMG-C6 cells. Both the increased ZO-1 expression and paracellular permeability induced by SHED-exos were abolished by insulin-like growth factor 1, a PI3K agonist. Slug bound to the ZO-1 promoter and suppressed its expression. For safer and more effective clinical application, SHED-exos were intraductally infused into the SMGs of NOD mice, and saliva secretion was increased and accompanied by decreased levels of p-Akt/Akt, p-GSK-3β/GSK-3β, and Slug and increased ZO-1 expression. CONCLUSION Local application of SHED-exos in SMGs can ameliorate Sjögren syndrome-induced hyposalivation by increasing the paracellular permeability of glandular epithelial cells through Akt/GSK-3β/Slug pathway-mediated ZO-1 expression.

ObjectiveTo analyze the research hotspots and frontier trends in the field of early screening tools of autism spectrum disorder (ASD) over the past two decades. MethodsThe literature on early screening tools for ASD was searched in Web of Science core collection database from 2002 to 2022. CiteSpace was used for cluster analysis of keywords, to draw knowledge mapping. Research disciplines were analyzed and comprehensively interpreted. ResultsA total of 115 articles were included. The number of researches on early screening tools for ASD had been increasing over the past two decades. The research disciplines with higher publication volume included pediatrics, neurology and neuroscience, and psychology. A total of 191 keywords were identified, and the LLR keyword clustering analysis yielded eleven clusters. ConclusionModified Checklist for Autism in Toddlers, Revised with Follow-up (M-CHAT-R/F) and Brief Infant-Toddler Social and Emotional Assessment (BITSEA) have been subjected to large-scale sample screening and follow-up observation for validity, demonstrating good psychometric properties and high clinical diagnostic value. The development of new early screening tools for ASD, validation of the reliability and validity of different language versions of the M-CHAT-R/F, and research on digital and networked M-CHAT-R/F are current research hotspots. Cultural adaptation of early screening tools for ASD and their application within the developmental monitoring framework may represent frontier research trends.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

The peripherally inserted central catheter (PICC) in neonates has solved the long-term venous access needs of hospitalized infants in the Neonatal Intensive Care Unit (NICU) . The application of technology is accompanied by the risk of complications. Providing safe and high-quality vascular access for neonates through standardized operations is of great significance. The National Association of Neonatal Nurses (NANN) has formulated the Practice Guideline for PICC in Neonates and revised it into the the Practice Guideline for Peripherally Inserted Central Catheter in Neonates (Third Edition) in 2015, aiming to support the bedside nursing practice of neonatal PICC, reduce the occurrence of complications, and promote neonatal safety. This article interprets the recommended points for early identification, management, and prevention of complications after neonatal PICC catheterization in the guidelines.

Objective:To investigate the diagnostic value of integrated 18F-fluorodeoxyglucose (FDG) PET/MRI multimodal imaging in the grading of adult diffuse gliomas. Methods:A retrospective analysis was performed; 29 patients accepted cranial 18F-FDG PET/MRI multimodal imaging and diagnosed as having adult diffuse gliomas in our center from January 2020 to December 2021 were chosen; their clinical and image data were collected. These patients were divided into low-grade group (WHO grading II, n=13) and high-grade group (WHO grading III and IV, n=16) according to the pathological results confirmed by surgery or biopsy. T1WI, T2WI, DWI, arterial spin labeling (ASL), magnetic resonance spectroscopy (MRS) and PET were performed in these patients. Differences in T1WI and T2WI signs between the two groups were compared. Differences in maximum standard uptake value (SUV max), apparent diffusion coefficient (ADC), choline/ N-acetylaspartate (Cho/NAA), NAA/creatine (Cr), Cho/Cr, relative cerebral blood flow (rCBF) between the two groups were compared. The diagnostic efficacies of above parameters in differentiating high-grade from low-grade adult diffuse gliomas were determined by receiver-operating characteristic (ROC) curves. The predictive probabilities for differentiating high-grade from low-grade adult diffuse gliomas using combined parameters were obtained by binary Logistic regression analysis. Results:There were no statistical differences in T1WI and T2WI signs, proportion of adjacent parenchyma edema, proportion of crossing the midline into the contralateral side, proportion of mass effect, proportion of cystic degeneration/necrosis, or site of growth between low-grade and high-grade groups ( P>0.05). The values of SUV max, ADC, Cho/NAA, Cho/Cr and rCBF were statistically different between the two groups, and the order of diagnostic efficiency was SUV max>ADC>Cho/NAA>rCBF>Cho/Cr>NAA/Cr. SUV max had the highest diagnostic efficacy in differentiating high-grade from low-grade adult diffuse gliomas with an area under the curve (AUC) of 0.894, a sensitivity of 75% and a specificity of 100%; the diagnostic efficacy of combined parameters (mean AUC>0.9) was higher than that of single parameter, and the combined parameters of SUV max and Cho/NAA showed the highest diagnostic efficacy with an AUC of 0.933, a sensitivity of 81.3% and a specificity of 92.3%. Conclusion:The 18F-FDG PET/MRI multimodal imaging is helpful in the grading diagnosis of adult diffuse gliomas, and combination of PET and MRS may play a greater role.
