The influence of bed sharing on children′s physical and psychological health has been concerned as one of the main types of sleep arrangements.At present, there are significant differences in bed sharing among children of different ages, groups, regions and races.There are also studies on the impact of bed sharing sleep on children′s health, on the one hand, it is conducive to breastfeeding, where infants get enough security; on the other hand, it leads to an increase in the incidence of sudden infant death syndrome, and an increase in the number of night awakenings.Therefore, it is important to understand the current research situation of bed sharing and its influences on children, thus to better promote children healthy growth.

Objective:To retrospectively analyze the clinical and genetic characteristics of six patients with Acromicric dysplasia due to variants of the FBN1 gene. Methods:Six patients who had visited the Affiliated Hospital of Qingdao University between February 2018 and October 2020 were selected as the study subjects. Clinical data of the patients were collected. High-throughput sequencing was carried out. And candidate variants were verified by Sanger sequencing.Results:All of the six patients had presented with severe short stature (< 3 s), brachydactyly, short and broad hands and feet. Other manifestations included joint stiffness, facial dysmorphism, delayed bone age, liver enlargement, coracoid femoral head, and lumbar lordosis. Genetic testing revealed that all had harbored heterozygous variants of the FBN1 gene. Patient 1 had harbored a c. 5183C>T (p.A1728V) missense variant in exon 42, which had derived from his father (patient 2). Patient 3 had harbored a c. 5284G>A (p.G1762S) missense variant in exon 43, which had derived from her mother (patient 4). Patient 5 had harbored a c. 5156G>T (p.C1719F) missense variant in exon 42, which was de novo in origin. Patient 6 had harbored a c. 5272G>T (p.D1758Y) missense variant in exon 43, which was also de novo in origin. The variants carried by patients 1, 3 and 6 were known to be pathogenic. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the FBN1: c. 5156G>T was rated as a pathogenic variant (PS2+ PM1+ PM2_Supporting + PM5+ PP3). Conclusion:All of the six patients had severe short stature and a variety of other clinical manifestations, which may be attributed to the variants of the FBN1 gene.

The arm span is the sum of the length of the arm and the width of the chest.It is highly correlated with height and can be used as an accurate and reliable alternative measure to estimate height.The arm span/height ratio reflects the relationship between long bones and the trunk and can be used to evaluate the body proportion.A correct understanding of the development patterns and characteristics of arm span can help pediatricians to find the deviation of body proportion in time, which is of great significance to the etiological analysis of short stature.

Objective:To construct a nomogram model predicting the occurrence of acute kidney injury (AKI) in patients with sepsis in the intensive care unit (ICU), and to verify its validity for early prediction.Methods:Sepsis patients admitted to the ICU of the Affiliated Hospital of Jining Medical University from April 2015 to December 2021 were retrospectively included, and those who met the inclusion criteria were randomly divided into training and validation sets at a ratio of 7:3. Univariate and multivariate logistic regression models were used to identify independent risk factors for AKI in patients with sepsis, and a nomogram was constructed based on the independent risk factors. Calibration curve, receiver operating characteristic (ROC) curve, and decision curve analysis (DCA) were used to evaluate the nomogram model.Results:741 patients with sepsis were included in the study, 335 patients developed AKI within 7 d of ICU admission, with an AKI incidence of 45.1%. Randomization was performed in the training set ( n=519) and internal validation set ( n=222). Multivariate logistic analysis revealed that acute physiology and chronic health status score Ⅱ, sequential organ failure score, serum lactate, calcitoninogen, norepinephrine dose, urea nitrogen, and neutrophil percentage were independent factors influencing the occurrence of AKI, and a nomogram model was constructed by combining these variables. In the training set, the AUC of the nomogram model ROC was 0.875 (95% CI: 0.767-0.835), the calibration curve showed consistency between the predicted and actual probabilities, and the DCA showed a good net clinical benefit. In the internal validation set, the nomogram model had a similar predictive value for AKI (AUC=0.871, 95% CI: 0.734-0.854). Conclusions:A nomogram model constructed based on the critical care score at admission combined with inflammatory markers can be used for the early prediction of AKI in sepsis patients in the ICU. The model is helpful for clinicians early identify AKI in sepsis patients.

ObjectiveTo explore the characteristics of oral sensory-motor function in children with functional articulation disorders (FAD). MethodsFrom June, 2021 to January, 2022, 61 children with FAD in the Department of Children's Health of the Affiliated Hospital of Qingdao University were as case group, 90 normal healthy children were as control group. They were assessed with Oral Sensory-Motor Assessment, and were compared among different genders and different ages. Hyperactivity problems were assessed using Conners Parent Symptoms Questionnaire, and their oral sensory-motor function were compared between patients with hyperactivity problem (n = 13) and without hyperactivity problem (n = 48). ResultsThe total score and the scores of oral sensation, mandibular motion, lip motion and tongue motion were significantly lower in the case group than in the control group (t > 4.471, P < 0.001). There were significant differences in the total score and motor function scores among different ages in the control group (H > 17.015, P < 0.001), and they increased with age. There were significant differences in the total score, oral sensory and motor function scores among different ages in the case group (H > 10.567, P < 0.01), and they increased with age. The total scores, and the scores of mandibular, lip and tongue movements were lower in the boys and girls of the case group than in the same gender of the control group (t > 2.49, P < 0.05). The total score and the scores of the lip and tongue movements were lower in boys than in girls in the case group (|Z| > 2.409, P < 0.05). There was no significant difference in the total score and other scores between the patients with hyperactivity problem and without hyperactivity problem (P > 0.05). ConclusionThe oral sensory-motor function is poor for children with FAD, and can develop with age in both normal and FAD children.

OBJECTIVE: To analyze the clinical features and genetic variants in a 13-month-old child with Bloom syndrome. METHODS: Clinical data of the child was collected. Genetic variants were detected by high-throughput sequencing and Sanger sequencing. RESULTS: The child was born at full term but was small for gestational age. His clinical features included loss of appetite, severe growth retardation, microcephaly, and small mandible. Genetic testing found that he had carried compound heterozygous c.1068+3A>C and c.1069-1G>C variants of the BLM gene, both of which were unreported previously. CONCLUSION Bloom syndrome is mainly characterized by severe growth retardation in infancy. The novel variants have expanded the variant spectrum of the BLM gene.

Objective: To explore the relationship between childhood depressive symptoms with behaviors and family factors, and to provide a new perspective for comprehensive treatment of depressive children. Methods: A total of 58 children diagnosed with depressive disorder were recruited as case group in Department of Child Health, Affiliated Hospital of Qingdao University. At the same time, 88 healthy children were selected as age and gender-matched control group. Depressive symptoms, behaviors and family factors in the two groups were investigated. SPSS 22.0 statistical software was used to describe and analyze the data. Results: The total score of CBCL scale in the case group was significantly higher than that in the control group(43.29±30.93, 20.24±12.93, P<0.01), and the number of positive factors was significantly higher than that in the control group(2.57±3.14, 0.97±1.80, P<0.01). The scores of introversion, extroversion, depression, compulsion, hyperactivity, aggression and social withdrawal in the case group were significantly higher than those in the control group(30.29±26.10, 17.10±16.53; 26.29±26.88, 17.45±16.99; 10.14±10.23, 3.48±3.14; 7.29±7.31, 4.83±5.26; 7.00±7.01, 4.86±4.38; 12.86±11.60, 8.38±8.90; 4.29±5.14, 2.72±3.01, P<0.01). There was no significant difference between the two groups in the scores of physical complaints and disciplinary violations (P>0.05). The scores of somatization, hostility and terror of SCL-90 in parents of children in case group were significantly higher than those in control group(17.58±4.05, 15.81±4.00; 9.66±2.67, 8.69±2.45; 8.03±1.49, 7.50±0.88, P<0.05). The score of SDS scale was positively correlated with the total score of CBCL scale, the number of positive factors, introversion, extroversion, depression, compulsion, hyperactivity, aggression and social withdrawal, and negatively correlated with parents’ marital status (P<0.01). Conclusion Depression is a common emotional disorder in childhood, which has a negative impact on learning and social performance. In the comprehensive treatment of children with depression, the importance of child behavior therapy and parental psychological counseling should be fully considered for mental health improvement.

Objective: To investigate the effects of 1, 25-dihydroxy vitamin D₃[1, 25(OH)₂D₃] on food allergy(FA) in mice and its mechanism. Methods: A total of 40 BALB/c mice were randomly divided into 5 groups, 8 in each group, including control group (group C) and FA model group (FA group), according to the dose of 1, 25(OH)₂D₃ intervention, the mice of the FA group were divided into FA₀ group (0), FA_l group [10 μg/(kg·d)], FA_m group [50 μg/(kg·d)] and FA_h group[100 μg/(kg·d)]. Egg albumin was used to establish a food allergy model, with different doses of 1, 25(OH)₂D₃ for gastric intervention, and the control group was replaced by 9 g/L saline.The serum levels of ovalbumin-immunoglobulin E(OVA-IgE), interleukin(IL)-9 and IL-17 of mice were measured by using enzyme linked immunosorbent assay after the last excitation, and HE staining and histopathological examination were carried out in the small intestine of mice. Results: Compared with group C, FA₀ group and FA_h group small intestinal mucosa in mice had different degrees of damage, partial peeling off, structure disorder, villi epithelial cell focal falls peeling off, necrosis, lamina propria edema, congestion, a large number of inflammatory cells infiltration, low but the FA_l group and FA_m group had light mucosa damage, intestinal epithelial basically intact, with integrity, no congestion, edema, and inflammatory cells infiltration to a lesser degree.The mean concentrations of serum IgE, IL-9 and IL-17 in different groups were statistically significant (F=40.770, 9.530, 5.624, all P<0.05). Compared with the FA₀ group [(41.87±3.19) ng/L], the OVA-IgE of the FA_l group [(22.71±4.77) ng/L] and the FA_m group [(16.34±2.81) ng/L] were significantly reduced (t=5.533, 11.835, all P<0.01), but there was no significant difference between the FA_h group [(36.29±6.52) ng/L] (t=1.673, P>0.05). Compared with the FA₀ group [(161.77±50.44) ng/L], the IL-9 levels of the FA_l group [(94.29±18.79) ng/L] and the FA_m group[(84.45±30.88) ng/L] were significantly lower (t=3.267, 3.366, all P<0.01), while that of the FA_h group [(36.29±6.52) ng/L] was not significantly lower (t=0.777, P>0.05). Compared with FA₀ group [(81.55±29.37) ng/L], IL-17 levels of FA_h group [(133.58±47.05) ng/L] was significantly increased (t=2.653, P<0.05), while IL-17 level of FA_l group [(79.41±25.15) ng/L] and FA_m group [(58.81±26.00) ng/L] were lower than that of FA₀ group [(81.55±29.37) ng/L], but the difference was not statistically significant (t=0.154, 1.640, all P>0.05). Conclusions Low, medium dose of 1, 25(OH)₂D₃ supplements can inhibit mice food allergies, but high doses of 1, 25(OH)₂D₃ improve performance in mice food allergies, and 1, 25(OH)₂D₃′s influence on the secretion of IL-9 is one that influences mechanism of food allergy.
