Objective:To analyze the clinical characteristics and cytokines expression characteristics in infants with mild and severe respiratory syncytial virus (RSV) infection.Methods:From May 2023 to December 2023, plasma samples and clinical information were collected from 16 infants with RSV infection and 14 control infants. Cytek Aurora flow cytometry (Cytek, America) and Enzyme linked immunosorbent assay (ELISA) were used to detect the expression levels of 25 cytokines after mild and severe RSV infection.Results:Cough and nasal obstruction were the main clinical manifestations in infants with mild RSV infection, accompanied by polypnea, wheezing and other symptoms. The main symptoms of severe RSV infection were cough and rales, accompanied by fever and polypnea. In comparison with the control group, the expression levels of IL-2, IL-4, IL-5, IL-6, IL-9, IL-13, IL-22, TNF-α, IFN-α, IFN-β, MIP-1β, I-TAC, ENA-78, GROα, Eotaxin, and MCP-1 in the RSV infection group all exhibited an upregulation trend. Both IP-10 and MIP-3α demonstrated a downward trend in the RSV infection group; however, there was no statistically significant difference ( P>0.05). The levels of IL-10, IFN-γ, MIP-1α, and IL-8 in the RSV infection group were significantly higher than those in the control group, whereas the levels of MIG, TARC, and RANTES in the RSV infection group were significantly lower than those in the control group ( P<0.05). The levels of IL-2, IL-4, IL-5, IL-6, IL-9, IL-10, IL-13, IL-22, IFN-β, IFN-γ, TNF-α, IL-8, I-TAC, MIP-1β, Eotaxin, and MCP-1 in the mild RSV infection group were significantly higher than those in the severe RSV infection group ( P>0.05). Among these, the levels of MIG, RANTES, TARC, MIP-3α, and ENA-78 in the mild infection group were all lower than those in the severe infection group. The expressions of ENA-78 and MIP-1α in the severe infection group were significantly higher than those in the mild infection group and also higher than those in the control group. There was no significant difference in IP-10 and GROα between the mild and severe RSV infection groups ( P>0.05). Conclusions:The differences in clinical features and cytokines between infants with mild and severe RSV infection provide important data support for the prevention and treatment of RSV infection in infants.

Objective In order to understand the current status and influencing factors of perioperative pulmonary rehabilitation knowledge,attitude,and practice among Chinese thoracic surgery nurses,and to provide references for managers to take targeted measures to improve their pulmonary rehabilitation knowledge,attitude,and practice level.Methods From August to October 2023,a convenience sampling method and cross-sectional descriptive survey were used to anonymously survey 1 167 thoracic surgery nurses from tertiary-level A cancer specialty hospitals and tertiary-level A general hospitals in 24 provinces through the Wenjuanxing platform.A general information questionnaire and a knowledge,attitude and practice questionnaire for lung cancer perioperative pulmonary rehabilitation nurses were used,including knowledge dimension(14 items),belief dimension(6 items),and behavior dimension(14 items),totaling 34 items.Univariate analysis and linear regression multivariate analysis were used to determine the influencing factors of the knowledge,attitude and practice level of thoracic surgery nurses in perioperative pulmonary rehabilitation.Results 1 089 nurses completed the investigation.The total standard score and the dimension scores on knowledge,attitude,and behavior of the perioperative pulmonary rehabilitation questionnaire for thoracic surgery nurses were(80.45±11.84)(73.72±14.68)(89.61±11.38)and(83.46±14.48),respectively.The nature of the hospital,whether there is an administrative position,whether the department carries out ERAS,and whether they have received pulmonary rehabilitation training are the influencing factors of the perioperative pulmonary rehabilitation knowledge,attitude,and practice level of thoracic surgery nurses(P＜0.05).Conclusion The knowledge,attitude,and practice of perioperative lung rehabilitation among thoracic surgery nurses are generally at a moderate level.However,their knowledge of perioperative lung rehabilitation is relatively insufficient,and there are many influencing factors.Managers should strengthen pulmonary rehabilitation training for thoracic surgery nurses,improve their knowledge reserves and evidence conversion capabilities,and coordinate cross-integration among multidisciplinary teams to improve their knowledge,attitude and practice in perioperative pulmonary rehabilitation.

Objective:To clarify the complex network structure between self-management levels and supportive care needs of patients undergoing maintenance hemodialysis, utilizing network analysis methods to identify the core and bridging nodes among the variables, thereby defining targets for nursing interventions to implement more precise care strategies.Methods:A cross-sectional survey was conducted from May to November 2023 among 302 outpatient maintenance hemodialysis patients at the hemodialysis centers of two healthcare institutions in Harbin (the Second Affiliated Hospital of Harbin Medical University and Heilongjiang Changjiang Nephrology Specialist Hospital). This involved the use of general information questionnaires, the Hemodialysis Patient Self-Management Scale, and the Supportive Care Needs Scale for Hemodialysis Patients. R language was employed for the network analysis.Results:A total of 300 valid questionnaires were collected, including 186 males and 114 females, with an age range of 23 to 88 years (mean age 55.00 ± 13.78 years). The scores for the dimensions of self-management among dialysis patients were as follows: problem-solving (3.38 ± 0.63), execution of self-care (3.16 ± 0.52), partnership (2.56 ± 0.69), and emotional processing (1.89 ± 0.63). The scores for the dimensions of supportive care needs among dialysis patients were: physiological needs (2.82 ± 1.08), psychological needs (1.51 ± 1.02), social needs (1.97 ± 1.07), emotional needs (1.67 ± 1.12), spiritual needs (2.22 ± 0.77), informational needs (2.83 ± 1.08), and practical needs (2.82 ± 1.03). In network analysis, the strongest intensity was found in the execution of self-care (1.753), and the highest closeness was in psychological needs (0.017). The top three dimensions ranked by bridge strength were social needs (1.463), partnership (1.462), and execution of self-care (1.384). The root mean square error was lowest for psychological needs (0.518) and emotional needs (0.538). The stability and accuracy of the network structure were found to be good.Conclusions:The key intervention targets for nursing care in maintenance hemodialysis patients were identified as executing self-care, psychological needs, emotional needs, and social needs. Among these, executing self-care served as the core intervention focus, while psychological and emotional needs had dominant influences, and social needs exhibited the strongest bridging role. Nursing staff should prioritize these key targets and tailor personalized comprehensive nursing intervention plans to enhance patients′self-management levels and fully meet their care needs.

Objective To explore the correlation between the pathogenesis of toxins damaging liver collateral and the incidence of type 2 diabetes mellitus(T2DM)based on the theory of five circuits and six qi.Methods A total of 986 patients with T2DM treated in the Department of Endocrinology and Metabolism at the Affiliated Hospital of Changchun University of Chinese Medicine from February 2019 to October 2023 were selected as the study subjects.The influences of circuit and qi indicators in the theory of five circuits and six qi on the constitutional characteristics of T2DM patients and the role of pathogenesis of toxins damaging liver collateral in the incidence of T2DM were investigated.Results(1)The five-circuit and six-qi analysis showed that the yearly circuit and sitian/zaiquan conditions had no significant effect on the constitutional characteristics of patients with T2DM(P＞0.05).However,dominant circuit,guest circuit,dominant qi and guest qi significantly influenced the constitutional characteristics of patients with T2DM(P＜0.05).For the distribution of circuit-qi indicators at birth among the 986 patients,dominant circuit was predominated by the terminal circuit of taiyang cold-water,guest circuit was characterized by deficient wood circuit or excessive water circuit,dominant qi was predominated by yangming dry-metal,and guest qi was characterized by taiyin damp-earth.(2)The correlation between the pathogenesis of toxins damaging liver collateral and the incidence of T2DM through comparative analysis revealed that the conveying and dispersing function of the liver plays a leading role in maintaining the body's yin-yang balance and ensuring free movement of qi,indicating that the critical role of toxins damaging liver collateral is the key to the incidence of diabetes.Conclusion Circuit-qi indicators have a certain influence on the constitutional characteristics of T2DM patients.The circuit-qi features at birth of the individuals prone to T2DM are as follows:dominant circuit predominated by the terminal circuit of taiyang cold-water,guest circuit characterized by deficient wood circuit or excessive water circuit,dominant qi being yangming dry-metal,and guest qi being taiyin damp-earth.Pathogenesis of toxins damaging liver collateral is closely related to the incidence of T2DM.Therefore,in treatment,the regulatory role of the liver should be emphasized,and liver-soothing herbs should be used based on syndrome differentiation,aiming for holistic treatment of the physique and the spirit and enhancing the therapeutic efficacy.The exploration will provide a new perspective and approach for the treatment of T2DM.

Objective:To explore the efficacy and safety of sirolimus in the treatment of diazoxide unresponsive congenital hyperinsulinism(CHI) and summarize the single-center experience.Methods:A retrospective analysis was conducted on the clinical data of 5 cases of CHI treated with sirolimus after ineffective treatment with diazoxide, admitted to the Children′s Hospital Affiliated to Zhengzhou University from January 2017 to December 2022. The efficacy and safety of sirolimus in the treatment of CHI were evaluated.Results:The study included 5 patients, 3 males and 2 females. The age of onset ranged from 1 to 90 days. Initial symptoms included poor mental state(2/5) and convulsions(3/5). Blood glucose levels were 1.1 to 2.3 mmol/L, and insulin levels ranged from 13.52 to 70.53 μIU/mL. Two cases were classified as diffuse type, and the histological type of 3 cases was unknown. Genetic testing confirmed the diagnosis, with whole-exome sequencing revealing an unreported novel mutation in 1 case(ABCC8 exon 25_28del). Of the five patients, three patients were treated with sirolimus after diazoxide and octreotide failed, one patient was treated after unresponsive diazoxide, and the other one was treated after diazoxide, octreotide, and even near-total pancreatectomy failed. The onset age of sirolimus therapy ranged from 1 to 20 months. The maximum dosage of sirolimus was 1.2-3.2 mg·m -2·d -1, and the duration of medication ranged from 2 to 12 months. One patient was fully responsive to sirolimus, and the other four patients were partially responsive. All patients achieved euglycemia with sirolimus alone or in combination with standard CHI treatment. During follow-up, non-infectious diarrhea, elevated carcinoembryonic antigen, elevated triglycerides, and elevated liver enzymes were observed. Conclusion:This study indicates that sirolimus has a certain degree of efficacy in CHI patients for whom diazoxide treatment is ineffective. However, the long-term efficacy and safety warrant further multicenter trials.

Objective:To explore the clinical characteristics and genetic variants of two children with 3-hydroxy-3-methylglutaryl-coenzyme A lyase deficiency (HMGCLD).Methods:Two children with HMGCLD diagnosed at Henan Provincial Children′s Hospital respectively in December 2019 and June 2022 were selected as the study subjects. Clinical data and results of laboratory testing were analyzed retrospectively.Results:Both children had manifested with repeated convulsions, severe hypoglycemia, metabolic acidosis and liver dysfunction. Blood amino acids and acylcarnitine analysis showed increased 3-hydroxy-isovalyl carnitine (C5OH) and 3-hydroxy-isovalyl carnitine/capryloyl carnitine ratio (C5OH/C8), and urinary organic acid analysis showed increased 3-hydroxyl-3-methyl glutaric acid, 3-methyl glutaric acid, 3-methyl glutacoic acid, 3-hydroxyisoglycine and 3-methylprotarylglycine. Child 1 was found to harbor homozygous c. 722C>T variants of the HMGCL gene, which was rated as uncertain significance(PM2_Supporting+ PP3). Child 2 was found to harbor homozygous c. 121C>T variants of the HMGCL gene, which was rated as pathogenic(PVS1+ PM2_Supporting+ PP4). Conclusion:Acute episode of HMGCLD is usually characterized by metabolic disorders such as hypoglycemia and metabolic acidosis, and elevated organic acids in urine may can facilitate the differential diagnosis, though definite diagnosis will rely on genetic testing.

Objective:To explore the clinical features and genetic variants in three children suspected for β-ketothiolase deficiency (BKTD).Methods:Clinical manifestations, laboratory examination and genetic testing of three children suspected for BKTD at Henan Children′s Hospital between January 2018 and October 2022 were collected, and their clinical and genetic variants were retrospectively analyzed.Results:The children were all males with a age from 7 to 11 months. Their clinical manifestations have included poor spirit, shortness of breath, vomiting, convulsions after traumatic stress and/or infection. All of them had severe metabolic acidosis, elevated ketone bodies in blood and urine, hypoglycemia, with increased isoprenyl-carnitine and 3-hydroxyisovalyl-carnitine in the blood, and 2-methyl-3-hydroxybutyrate and methylprotaroyl glycine in the urine. All of them were found to harbor compound heterozygous variants of the ACAT1 gene, including c. 1183G>T and a large fragment deletion (11q22.3-11q23.1) in child 1, c. 121-3C>G and c. 826+ 5_826+ 9delGTGTT in child 2, and c. 928G>C and c. 1142T>C in child 3. The variants harbored by children 2 and 3 were known to be pathogenic or likely pathogenic. The heterozygous c. 1183G>T variant in child 1 was unreported previously and rated as a variant of unknown significance (PM2_Supporting+ PP3+ PP4) based on guidelines from the American College of Medical Genetics and Genomics. The large segment deletion in 11q22.3-11q23.1 has not been included in the DGV Database and was rated as a pathogenic copy number variation. Conclusion:The variants of the ACAT1 gene probably underlay the pathogenesis of BKTD in these three children.
