Objective:To describe the prevalence of food allergy among children aged 0-5 years in China and to explore related influencing factors.Methods:Multistage stratified random sampling method was used to collect data from 275 surveillance sites of the China National Nutrition and Health Survey of Chinese children and lactating mothers programs in 31 provinces (autonomous regions and municipalities) of China in 2016-2017. A total of 70 107 participants aged 0-5 years were included in this study. The study collected information of participants' demographic characteristics and food allergies by face-to-face questionnaire. The prevalence of food allergy was analyzed, using the complex data weighting method. The logistic regression models were used to analyze the influencing factors related to food allergy.Results:The overall prevalence of self-reported food allergy among children aged 0-5 years was 4.81%. Prevalence rates in infants aged 0-5 months, and 6-23 months and preschool children aged 2-5 years were 0.81%, 4.68% and 5.26%, respectively. The results of logistic analysis showed that there was a significantly positive correlation between factors including children from 6 months to 5 years old, urban area, southwest area, first-born, mothers with college education or above, and the prevalence of food allergy in children. Shrimp, poultry eggs, crab shellfish, fruit, milk and fish appeared the common allergic foods in children aged 0-5 years, with prevalence rates of self-reported food allergy as 1.55%, 1.25%, 0.99%, 0.97%, 0.87% and 0.86%, respectively. The proportion of single food allergy in children with allergies was 69.85%.Conclusions:Among children aged 0-5 years, the prevalence of self-reported food allergy increases with age, in China. Foods that is prone to allergies include fish, shrimp, crab, shellfish, poultry eggs, milk and fruits, etc. Most allergies were only caused by single food in children, under observation.

Objective:To investigate the clinical characteristics and management status of children with Turner syndrome (TS) in China.Methods:As a cross-sectional study, 1 089 TS patients were included in the database of the National Collaborative Alliance for the Diagnosis and Treatment of Turner Syndrome from August 2019 to November 2023. Clinical characteristics (growth development, sexual development, organ anomalies, etc.), karyotypes, auxiliary examinations, and treatments were collected and analyzed.Results:Among the 1 089 TS cases, 809 were recorded karyotypes. The karyotype distribution was as follows: 45, X in 317 cases (39.2%), X chromosome structural variants (including partial deletions of p or q arm, ring chromosome, and marker chromosome) in 89 cases (11.0%), 45, X/46, XX mosaicism in 158 cases (19.5%), mosaicism with X chromosome structural variants in 209 cases (25.8%), and presence of Y chromosome material in 36 cases (4.4%). Among the 824 TS cases, the age of diagnosis was 9.7(6.4, 12.2) years, with a height standard deviation score (HtSDS) of -3.1±1.2. Five hundred and fifty three cases underwent growth hormone (GH) stimulation test, and 352 cases (63.7%) had GH peak values <10 μg/L and 75.9% (577/760) had low IGF1 levels, with IGF1 SDS ≤-2 accounting for 38.2% (290 cases). Among 471 cases aged ≥8 years, 132 cases (28.0%) showed spontaneous sexual development (mean bone age (11.0±1.7) years), 10 cases had spontaneous menarche (mean bone age (12.0±2.2) years), and 2 cases had regular menstrual cycles. Common physical features included cubitus valgus (311 cases (28.5%)), neck webbing (188 cases (17.2%)), low posterior hairline (185 cases (17.0%)), shield chest (153 cases (14.0%)), high arched palate (127 cases (11.6%)), short fourth metacarpal (43 cases (3.9%)), and spinal abnormalities (38 cases (3.5%)). Congenital cardiovascular and urogenital anomalies occurred in 91 cases (19.4%) and 66 cases (12.0%)respectively. Abdominal ultrasound in 33 cases (7.2%) indicated fatty liver, hepatomegaly, intrahepatic bile duct stones, and splenomegaly. Among 23 cases undergoing oral glucose tolerance test (OGTT) test, 2 were diagnosed with diabetes mellitus and 4 with impaired glucose tolerance. Following diagnosis, 669 cases (80.7%) received rhGH treatment at a chronological age of (9±4) years and bone age of (8.3±3.2) years. Additionally, 112 cases (19.4%) received sex hormone replacement therapy starting at the age of (14±4) years and bone age of (12.6±1.2) years.Conclusions:The karyotypes of 45, X and mosaicism were most common in Chinese children with TS. The clinical manifestations were mainly short stature and gonadal dysplasia. However, a few TS children could be in the normal range of height, and some cases among those aged of ≥8 years old had spontaneous sexual development. Some exhibited physical features, congenital cardiovascular and urogenital anomalies, and dysfunction of the hypothalamic-pituitary-IGF1 axis. Moreover, a few of them developed impaired glucose tolerance and diabetes mellitus. Following diagnosis, most of the patients received rhGH treatment, and a few of them received sex hormone replacement therapy.

Background::Hypothermia therapy has been suggested to attenuate myocardial necrosis; however, the clinical implementation as a valid therapeutic strategy has failed, and new approaches are needed to translate into clinical applications. This study aimed to assess the feasibility, safety, and efficacy of a novel selective intracoronary hypothermia (SICH) device in mitigating myocardial reperfusion injury.Methods::This study comprised two phases. The first phase of the SICH was performed in a normal porcine model for 30 minutes ( n = 5) to evaluate its feasibility. The second phase was conducted in a porcine myocardial infarction (MI) model of myocardial ischemia/reperfusion which was performed by balloon occlusion of the left anterior descending coronary artery for 60 minutes and maintained for 42 days. Pigs in the hypothermia group ( n = 8) received hypothermia intervention onset reperfusion for 30 minutes and controls ( n = 8) received no intervention. All animals were followed for 42 days. Cardiac magnetic resonance analysis (five and 42 days post-MI) and a series of biomarkers/histological studies were performed. Results::The average time to lower temperatures to a steady state was 4.8 ± 0.8 s. SICH had no impact on blood pressure or heart rate and was safely performed without complications by using a 3.9 F catheter. Interleukin-6 (IL-6), tumor necrosis factor-α, C-reactive protein (CRP), and brain natriuretic peptide (BNP) were lower at 60 min post perfusion in pigs that underwent SICH as compared with the control group. On day 5 post MI/R, edema, intramyocardial hemorrhage, and microvascular obstruction were reduced in the hypothermia group. On day 42 post MI/R, the infarct size, IL-6, CRP, BNP, and matrix metalloproteinase-9 were reduced, and the ejection fraction was improved in pigs that underwent SICH.Conclusions::The SICH device safely and effectively reduced the infarct size and improved heart function in a pig model of MI/R. These beneficial effects indicate the clinical potential of SICH for treatment of myocardial reperfusion injury.

All indexes of writing quality of nursing documents were significantly improved, and scores of nurses' system use experience were improved, compared with those before the system application, the differences were statistically significant ( P<0.05) . Conclusions:The clinical decision support system for dialectical nursing of traditional Chinese medicine of lumbar disc herniation can improve the clinical efficacy of patients, relieve pain, improve the mastery of health care knowledge, improve the homogeneity, continuity and integrity of nurses' dialectical nursing, and nurses have a good experience of the system.

Laparoscopic proximal gastrectomy (LPG) can be selected for the treatment of early upper gastric carcinoma, but gastroesophageal reflux after operation would seriously affect the quality of life of patients. Esophagogastric anastomosis with double flap technique is a digestive tract reconstruction method using the anastomosis between the esophagus and the anterior wall of the stomach. Compared with other digestive tract reconstruction methods, esophagogastric anastomosis with double flap technique can maintain the postoperative body mass of patients in good condition, improve the nutritional status and the long-term quality of life of patients. Esophagogastric anasto-mosis with double flap technique has good anti reflux effects and retain the possibility of endoscopic examination and treatment. By reviewing literatures at home and abroad, and combined with clinical experiences, the authors discuss current status and digestive tract reconstruction methods of LPG, and deeply investigate the application prospect of esophagogastric anastomosis with double flap technique.

Idiopathic pulmonary fibrosis (IPF) is a progressive disease with unknown etiology and limited therapeutic options. Activation of fibroblasts is a prominent feature of pulmonary fibrosis. Here we report that lncRNA DACH1 (dachshund homolog 1) is downregulated in the lungs of IPF patients and in an experimental mouse model of lung fibrosis. LncDACH1 knockout mice develop spontaneous pulmonary fibrosis, whereas overexpression of LncDACH1 attenuated TGF-β1-induced aberrant activation, collagen deposition and differentiation of mouse lung fibroblasts. Similarly, forced expression of LncDACH1 not only prevented bleomycin (BLM)-induced lung fibrosis, but also reversed established lung fibrosis in a BLM model. Mechanistically, LncDACH1 binding to the serine/arginine-rich splicing factor 1 (SRSF1) protein decreases its activity and inhibits the accumulation of Ctnnb1. Enhanced expression of SRSF1 blocked the anti-fibrotic effect of LncDACH1 in lung fibroblasts. Furthermore, loss of LncDACH1 promoted proliferation, differentiation, and extracellular matrix (ECM) deposition in mouse lung fibroblasts, whereas such effects were abolished by silencing of Ctnnb1. In addition, a conserved fragment of LncDACH1 alleviated hyperproliferation, ECM deposition and differentiation of MRC-5 cells driven by TGF-β1. Collectively, LncDACH1 inhibits lung fibrosis by interacting with SRSF1 to suppress CTNNB1 accumulation, suggesting that LncDACH1 might be a potential therapeutic target for pulmonary fibrosis.

Objective : To explore the epicardial adipose tissue ( EAT) of patients with coronary heart disease , KLF7 stimulates macrophages to secrete inflammatory factors and promotes the differentiation and maturation of adipocytes through the NF⁃κB signaling pathway , and to clarify the mechanism of KLF7 in the occurrence and development of CAD. Methods : 30 patients with coronary heart disease ( CAD group) and 30 patients without coronary heart disease (non⁃CAD group) were collected , and general data and biochemical indicators were collected. qRT⁃PCR was used to detect the expression levels of KLF7 , APN , IL⁃6 , and TNF⁃α mRNA in EAT. Human THP⁃1 cells were cultured in vitro and induced into M1 type macrophages and 3T3 ⁃L1 preadipocytes. The cells were divied into 3 groups : KLF7 up⁃regulated group ( transfected with KLF7 mimic) , KLF7 down⁃regulated group ( transfected with siRNA knockdown KLF7 ) , NC group ( transfected oligopeptide sequence) , transfected two kinds of cells. qRT⁃PCR was used to detect the expression of APN , MCP⁃1 , IL⁃6 and TNF⁃α mRNA in M1 type macrophages , and the protein expression levels of key factors in the NF⁃κB signaling pathway were detected by Westren blot. The qRT⁃PCR method was used to detect APN , KLF4 , IL⁃6 , MCP⁃1 mRNA and adipocyte differentiation marker peroxisome proliferator⁃activated receptor⁃γ (PPARγ) in 3T3 ⁃L1 preadipocytes 24 h after transfection. CCAAT/enhancer binding protein α (C/EBPα ) , fatty acid binding protein 4 (FABP4) mRNA relative expression levels , and Westren blot was used to detect protein expression levels. Results : Compared with the non⁃CAD group , the expression of CAD group decreased , APN decreased , IL⁃6 and TNF⁃α increased significantly , and the difference was statistically significant (P < 0. 01) . KLF7 was highly expressed in human THP⁃1 derived M1 macrophages induced by inflammatory stimuli (LPS) . In M1 macrophages derived from human THP⁃1 , knocking down KLF7 could inhibit the release of inflammatory factors. Transfection with KLF7 ⁃siRNA could significantly inhibit LPS⁃induced phosphorylation of JNK⁃MAPKs , the level of p⁃p65 and the activation of p ⁃IκBa (P < 0. 05) . In 3T3 ⁃L1 preadipocytes , upregulation of KLF7 increased the expression of adipocyte differentiation markers PPARγ , C/EBPa , FABP4 mRNA , and promoted the differentiation of 3T3 ⁃L1 preadipocytes into adipocytes (P < 0. 05) . Conclusion The expression of KLF7 in EAT in CAD patients increases. KLF7 activates the activation of macrophages mediated by the JNK⁃NF⁃KB signaling pathway in EAT , promotes inflammation in EAT in CAD patients , and promotes the differentiation and maturation of adipocytes , thereby promoting the development of CAD. It indicates that KLF7 may be a potential therapeutic target for cardiovascular diseases (such as CAD) .

To construct TeI3c/4c-based and temperature-inducible gene inactivation system (Thermotargetron) and to apply it to gene inactivation of mesophilic bacteria. The subunit of flagellum (fliC) and C4 dicarboxylate orotate:H⁺ symporter (dctA) genes were chosen as targets in the genome of Escherichia coli HMS174 (DE3) strain. According to recognition roles of TeI3c/4c intron, the fliC489a, fliC828s, fliC1038s and dctA2a sites were chosen as target sites. Gene-targeting plasmids were constructed based on pHK-TT1A by using overlap PCR method and transformed into HMS174 cells. An aliquot mid-log phase cultures of the transformants were shocked at 48 °C and plated on LB plate (containing chloramphenicol). Afterwards, gene mutants were screened by using colony PCR and DNA sequencing. After the mutants were obtained, the phenotypes of ΔfliC and ΔdctA gene mutants were characterized by using agar puncture and carbon metabolism experiments. Colony PCR and sequencing results show that TeI3c/4c intron was inserted in the designed sites of fliC and dctA genes. The gene-targeting efficiency of Thermotargetron system was 100%. Phenotype verification experiments of the mutants demonstrated that the cell motility of all ΔfliC mutants was damaged and the malate assimilation ability of ΔdctA mutant was deprived comparing to wild-type HMS174 strain. In our study, a temperature-inducible and high-efficiency gene inactivation system was established for mesophilic bacteria. This system could achieve high efficiency and precise gene inactivation by modulation of the incubation duration of the transformants at 48 °C.
