OBJECTIVETo discuss the effect of electric coagulation through bronchoscopy in diagnosis and treatment of congenital vallecular cyst in children.

METHODTen cases of congenital vallecular cyst in the study with age ranged from 21 days to 4 years and 10 months were treated with electric coagulation through bronchoscopy. The therapeutic effect was evaluated by endoscopic and clinical manifestation. And all the patients were followed-up for 6-12 months.

RESULTAll the patients obtained 3-5 times electric coagulation. After the operation, the cyst decreased in size, epiglottis softening was subsided, uplift uncompression, dyspnea and laryngeal stridor were improved obviously. After follow-up periods of 6-12 months, no capsule wall were left, and the activity of the epiglottis resumed.No severe complication was found in any patient.

CONCLUSIONElectric coagulation through bronchoscopy is a simple, effective and safe method to treat congenital vallecular cyst in children.

Chinese Journal of Pediatrics.2013;51(11):842-845.

OBJECTIVETo explore the diagnostic and therapeutic methods for perioperative children with congenital heart disease (CHD) with airway stenosis in pediatric intensive care unit (PICU).

METHODFiberoptic bronchoscopy was used for the diagnosis of 100 CHD cases in PICU who were clinically considered to have possible airway malformation because of complicated difficult-to-control lung infection, atelectasis and failure with the ventilator after surgery from January 2010 to October 2011. Cases who were confirmed to have severe airway stenosis by bronchoscopy and weaning from the ventilator after surgery were treated with balloon expandable stents into the desired position in the bronchoscopy.

RESULTThere were 73 cases (73%) of CHD patients with airway abnormalities, including 31 cases of severe stenosis (31%), moderate stenosis in 29 cases (29%), mild stenosis in 13 cases (13%). Nine of the 10 children in whom the mechanical ventilation was hard to be stopped after surgery because of severe airway stenosis were weaned from mechanical ventilation successfully by fiberoptic bronchoscopy, while one case died from primary disease with severe sepsis after the placement of bronchial stents.

CONCLUSIONCHD children with difficult-to-control lung infection, atelectasis and failure with ventilator after surgery are often complicated with airway abnormalities. The therapeutic bronchoscopy with airway stent can be used for cases with weaning from the ventilator because of severe airway stenosis.

OBJECTIVEMultiple sulfatase deficiency is a rare autosomal recessively inherited lysosomal storage disorder characterized by the accumulation of sulfated lipids and acid mucopolysaccharides. The aim of this study was to explore the clinical manifestations, enzyme activities and SUMF1 gene mutations in two Chinese patients with multiple sulfatase deficiency.

METHODOne boy and one girl from two families were studied. Both patients presented with mental retardation, mild coarse facial features, a neurodegenerative course of disease with loss of sensory and motor function after 2 years of age, ichthyosis and skeletal abnormalities (kyphosis or/and scoliosis). Clinical characteristics indicate multiple sulfatase deficiency.Sulfatases activities in blood leucocytes, plasma or cultured fibroblast of the patients were measured.Genomic DNAs were extracted from peripheral blood leukocytes from the patients and their parents. All SUMF1 gene exons and intron-exon boundaries were amplified by PCR and subjected for direct sequencing.

RESULTIn case 1, five sulfatases activities of blood leucocytes and four sulfatases of cultured skin-fibroblasts were analyzed.In case 2, three sulfatases activities of blood leucocytes were tested.Significantly decreased sulfatases activities confirmed the diagnosis of multiple sulfatase deficiency.On SUMF1 gene, c.793_794 insATG (p. P265X)/ c.1045C>T (p.R349W) in case 1 and c.451A>G (p.K151E)/ c.1046G>C (p.R349Q) in case 2 were detected, respectively. Three novel mutations c.793_794insAGT, c.1046G>C and c.451A>G were identified.

CONCLUSIONSMultiple sulfatase deficiency usually results in multi-organ damage, especially neurologic, skeletal and skin.Sulfatases assay and SUMF1 gene analysis are necessary for the diagnosis. Two Chinese cases with multiple sulfatase deficiency were firstly reported. Three novel mutations were found.It should be considered that the mutation profile of SUMF1 gene in Chinese patients is different from other populations.

OBJECTIVETo evaluate the efficacy of specific sublingual immunotherapy (SLIT) with Dermatophagoides farinae drops on children with allergic asthma and allergic rhinitis of the preschool and school-age groups of children and adolescents.

METHODThis study analyzed the efficacy of SLIT in 122 children (aged 3-14 yr) with house dust mites-induced allergic asthma and allergic rhinitis. According to the age, patients were defined as the preschool group ( ≤ 6 years old, n = 59) and school-age group (> 6 years old, n = 63). All children were treated with Dermatophagoides farinae drops for at least 2 years. Clinical observation and follow-up study were conducted during the treatment. Before and after SLIT for half a year, 1 year and 2 years, asthma symptom scores (day and night), rhinitis symptom scores and medication scores were evaluated. The adverse events were assessed during the study.

RESULTAfter SLIT for half a year, 1 year and 2 years, there were no significant differences between the preschool group (0.3 ± 0.5,0.0 ± 0.1,0.0 ± 0.0) and school-age group (0.3 ± 0.4,0.0 ± 0.1,0.0 ± 0.0) in day scores of asthma (Z value was -1.687, -0.613,0.000, all P > 0.05). There were no significant differences between the preschool group (0.2 ± 0.5,0.1 ± 0.3,0.0 ± 0.0) and school-age group (0.2 ± 0.4,0.1 ± 0.3, 0.0 ± 0.0) in night scores of asthma (Z value was -0.496, -0.486,0.000, all P > 0.05). There was no significant differences between the preschool group (1.4 ± 0.9,0.4 ± 0.5,0.1 ± 0.3) and school-age group (1.3 ± 0.9,0.5 ± 0.6,0.2 ± 0.4) in symptom scores of allergic rhinitis (Z value was -0.394, -1.166, -1.075, all P > 0.05). There were no significant differences between the preschool group (1.6 ± 0.8,0.0 ± 0.0,0.0 ± 0.0) and school-age group (1.7 ± 0.7,0.0 ± 0.0,0.0 ± 0.0) in medication scores of allergic rhinitis (Z value was -0.655,0.000,0.000, all P > 0.05). After SLIT for 2 years, most children in the preschool and school-age groups were no longer using asthma controlling medication, with no significant difference between the two groups (Z value was 0.000, P > 0.05). The overall incidence of adverse reactions was only 7%, and there was no significant difference in the incidence of adverse reactions between the two groups (χ(2) = 0.000, P > 0.05). The local adverse events were mild gastrointestinal discomfort and rash, a majority of local adverse events in the preschool group were diarrhea. No severe adverse events happened in the treatment.

CONCLUSIONSLIT with Dermatophagoides farinae drops is safe and effective in children with allergic asthma and allergic rhinitis of the preschool and school-age groups of children and adolescents, which provides evidences for early SLIT intervention of the disease.

Chinese Journal of Pediatrics.2013;51(11):825-830.

OBJECTIVETo examine the effects of niacin on lysophosphatidylcholine (LPC)-induced intercellular adhesion molecule-1 (ICAM-1), and gained insight to the mechanisms.

METHODHuman umbilical vein endothelial cell line was cultured using Medium 200 medium in incubator at 37 °C and 5% CO2 condition.Experimental groups:(1) the negative control group:medium; (2) LPC different time groups:the medium added with 20 µmol/L final concentration of LPC, were cultured for 10 min and 8 h, 24 h; (3) LPC+ p38-mitogen-activated protein kinase (p38MAPK) inhibitor (SB203580) group:the medium added with 10 µmol/L p38MAPK inhibitor (SB203580) was cultured for 1 h, then human umbilical vein endothelial cells (HUVECs) added with the LPC were cultured for 10 min, 8 h and 24 h.(4) LPC+different niacin dose group:after separately adding with 0.25, 0.5, 1 mmol/L niacin, the cells were cultured for 18 h, then HUVECs added with the LPC were cultured for 10 min, 8 h and 24 h. Cell concentration in each group was 5×10(5)/ml, inoculated in 6-well plates, each well 1 ml. Detected by Western blot analysis of pp38MAPK, ICAM-1 protein content, real-time quantitative PCR to detect endothelial cell ICAM-1 mRNA expression, cell immunofluorescence to detect LPC-induced ICAM-1 protein expression.

RESULTIn LPC 24 h group, the expression of ICAM-1 protein was significantly increased 0.786 ± 0.02, the LPC+niacin group, ICAM-1 protein levels (0.487 ± 0.015) was significantly lower than the LPC 24 h group (P < 0.01), in LPC+SB203580 intervention group, ICAM-1 protein levels (0.461 ± 0.011) was significantly lower than that of the LPC 24 h group (P < 0.01), but did not reach the level of the control group. Adding LPC to culture for 10 min, phosphorylation of p38MAPK (pp38MAPK) reached its peak (0.47 ± 0.02), niacin could reduce the pp38MAPK (0.07 ± 0.02), SB203580 could also reduce its activity (0.11 ± 0.02). Adding LPC to culture for 8 h, ICAM-1 mRNA expression (8.16 ± 0.15) compared with the control group (1.00 ± 0.02) had a significant increase (t = 24.34, P < 0.01). Compared with the LPC 8 h, niacin reduced LPC-induced ICAM-1 mRNA expression (3.85 ± 0.14), and showed a dose-dependent manner (F = 8.06, P < 0.01), while SB203580 could not effectively reduce the ICAM-1 mRNA (8.09 ± 0.11).

CONCLUSIONNiacin prevented LPC-induced endothelial dysfunction by reducing expression of ICAM-1. These mechanisms appeared to be at least partly mediated by suppression of the pp38MAPK in endothelial cells. These pleiotropic effects of niacin may potentially contribute to the beneficial effects of risk reduction for atherosclerotic disease.

Chinese Journal of Pediatrics.2013;51(11):819-824.

OBJECTIVETo observe the effects of hemofiltration at early stage of septic shock with different ultrafiltration doses, including hemodynamics, oxygen metabolism, inflammatory mediator in piglet models, and to evaluate the therapeutic effects of HVHF.

METHODThe 18 healthy young piglets (Shanghai species) were divided randomly into three groups:control group (n = 6), conventional volume hemofiltration (CVVH) group [n = 6, ultrafiltration volume = 30 ml/(kg·h)] and high volume hemofiltration (HVHF) group [n = 6, ultrafiltration volume = 50 ml/(kg·h)], the animal model of septic shock was established by injection of lipopolysaccharide (LPS) (150 µg/kg) O111: B4. During the experiment, the following observations were carried out for all groups:1) Changes of hemodynamics [heart rate (HR), mean arterial pressure (MABP), cardiac output (CO), systemic vascular resistance index (SVRI), intrathoracic blood volume (ITBV)] and oxygen metabolism [oxygen delivery (DO2), oxygen consumption (VO2), oxygen extraction rate (O2ER) ] at the time of B0h, 0 h, 2 h, 4 h and 6 h.2) changes of TNF-α, IL-6, IL-10 in plasma at different time points (B0h, 0 h, 2 h, 4 h, 6 h).

RESULTSignificant difference in circulatory parameters, inflammatory mediators in plasma were found at B0h and 0 h among three groups; the CO in two treatment groups were higher than that in control group at 4 h, 6 h after model establishment (P < 0.05), and SVRI in HVHF groups were higher than that in other two groups at 4 h, 6 h after model was established (P < 0.05). The MABP in HVHF group [4 h (82 ± 17) mm Hg, 6 h (80 ± 12) mm Hg](1 mm Hg = 0.133 kPa) were higher than that in CVVH group at 4 h [(67 ± 12) mm Hg], 6 h [(69 ± 14) mm Hg] after model was established (P < 0.05). The levels of IL-6, IL-10, TNF-α in two treatment groups were lower than that in control group at 4 h and 6 h after model was established (P < 0.05), and the IL-6 [(281 ± 51) pg/ml], TNF-α [(67 ± 13) pg/ml] level in HVHF group was lower than that in CVVH group [IL-6(281 ± 51) pg/ml, TNF-α (67 ± 13) pg/ml] at 6 h (P < 0.05). The DO2 and VO2 in two treatment groups were higher than that in control group at 4 h, 6 h (P < 0.05), the O2ER in HVHF group were higher than that in CVVH group at 4 h (44% ± 3% vs. 33% ± 4%), 6 h (43% ± 5% vs. 31% ± 3%, P < 0.05).

CONCLUSIONHigh volume hemofiltration (HVHF) at early stage of septic shock piglet models was more effective in improving hemodynamics, oxygen metabolism than conventional CVVH. And HVHF eliminated blood inflammatory mediators more effectively than conventional CVVH.

OBJECTIVETo analyze the phenotype and genotype of CMTX1 patients with episodic transient reversible white matter involvement, and delineate the features of brain MRI in the episode and the possible mechanisms.

METHODThree Chinese probands and their family members were sequenced in the coding regions of GJB1. With the other 16 reported CMTX1 patients with episodic transient reversible white matter involvement, the clinical feature of the episodic central nervous system symptoms and the genotypes were reviewed.

RESULTMissense mutations in GJB1 were identified in all 3 probands. In 19 patients with transient reversible white matter involvement, the episodes were manifested as weakness of the limbs, dysarthria, and dysphagia, without disturbance of consciousness or seizures. The episodes lasted for 13 hours (10 min-72 hours) with complete remission in all patients; There were multiple episodes in 9 patients. During the episode, brain MRI showed symmetrical high signals in T2 weighted, Flair and DWI images in periventricular white matter, with predominance in posterior region including splenium of corpus callosum. These changes in imaging were most prominent during or within 1 week after the clinical episode.Significant improvements occurred within 1 month, with complete remission within 4-6 months.No specific locations of mutant amino acids in GJB1 protein were found in these patients with episodic transient reversible white matter involvement.

CONCLUSIONEpisodic transient reversible white matter involvement may present in a small number of patients with CMTX1. Transient edema of oligodendrocytes due to the dysfunction of gap junction may be involved in the pathogenesis. There is no correlation between the location of the mutant amino acids in GJB1 and the occurrence of the episodes.

OBJECTIVETo evaluate the effect of combined use of stanazolol (ST) on the final adult height (FAH) in girls with idiopathic central precocious puberty (ICPP) and apparently decreased linear growth during gonadotropin-releasing hormone analog (GnRHa) therapy.

METHODSixty-three girls with ICPP and decreased velocity of growth of height (HV<4 cm/yr) during GnRHa therapy were divided into 3 groups based on the following types of interventions:group 1 (n = 20), GnRHa+ST [25-30 µg/(kg·d) every 3-month followed by 3-month discontinuation], group 2 (n = 21), GnRHa+recombinant human growth hormone [rhGH, 1-1.1 U/(kg·w)], group 3 (n = 22), GnRHa alone.HV, the advancement of bone age (BA) for chronological age (CA) (ΔBA/ΔCA) and FAH were compared among groups.

RESULT(1)Total duration of ST combination therapy was (12.22 ± 3.62) months, while total duration of combination of rhGH was (13.22 ± 6.80) months. (2)HV increased significantly in both group 1 [ (2.79 ± 0.60) cm/yr vs. (6.27 ± 1.98) cm/yr, P < 0.01] and in group 2 [(2.80 ± 0.50) cm/yr vs. (6.25 ± 1.98) cm/yr, P < 0.01] during combined therapy, but maintained at low levels in group 3 [(3.95 ± 1.10) cm/yr vs. (3.34 ± 0.95) cm/yr, P > 0.05].No significant differences of ΔBA/ΔCA were found among the three groups [0.25(0.11∼0.28), 0.22(0.15∼0.31),0.19(0.10∼0.32), P > 0.05]. (3)FAH was significantly higher than predicted adult height (PAH) before combined therapy, as well as higher than target height (THt) in both group 1 [(156.25 ± 2.90) cm vs. (150.78 ± 3.70) cm, P < 0.01, (156.25 ± 2.90) cm vs. (153.94 ± 2.62) cm, P < 0.01], and in group2 [ (157.33 ± 4.69) cm vs. (152.61 ± 3.92) cm, P < 0.01, (157.33 ± 4.69) cm vs. (154.39 ± 4.72) cm, P = 0.01].In group 3, FAH was similar to PAH [(153.88 ± 2.6) cm vs. (152.54 ± 5.86) cm, P > 0.05], and was less than THt [(153.88 ± 2.6) cm vs. (155.60 ± 4.52) cm, P = 0.02]. (4)In girls treated with ST, no hirsutism, clitorism or hoarse voice was recorded.No polycystic ovary syndrome was found by B-mode ultrasound.

CONCLUSIONIntermittent combined use of low dose ST therapy can increase HV and thus improve FAH in girls with ICPP and apparently decreased linear growth during GnRHa therapy.

OBJECTIVETo measure the prevalence, the possible causes and the influencing factors of allergy, food hypersensitivity and food intolerance in 0-36 month old infants in 8 cities in China.

METHODTotally 2632 infants from the outpatient departments of prevention and health care of two representative hospitals in 8 Chinese cities were randomly selected by applying multistage cluster sampling method from October 2011 to March 2012, and a one-on-one survey to infants' parents was conducted to investigate infants' sensitization status.

RESULTSelf-reported infant allergy rate was 17.97% (473/2632) ; self-reported food hypersensitivity and food intolerance rates were 6.53% (172/2632) and 4.26% (112/2632) , respectively. The proportion of self-reported food hypersensitivity of 0-12 months old infants was 4.47% (74/1656) and their top five allergens in a descending order were eggs (28.38%) , shrimp (25.68%) , fish (21.62%) , milk (18.92%) and wheat (4.05%) . The proportion of self-reported 13-36 months old infant's food hypersensitivity was 10.05% (98/976) . The top five allergens were shrimp (33.93%) , fish (26.79%) , eggs (23.21%) , milk (12.50%) and soy (3.57%) in 13-24 months group, while fish (38.24%) , shrimp (35.29%) , eggs (20.59%) , milk (20.59%) and peanuts (2.94%) in 25-36 months group. Both 7-12 and 13-24 month old were the highest incidence (both of them were 11.98%, 58/484) of age for developing food hypersensitivity and 7-12-month old was also the highest incidence (8.47%, 41/484) of age for food intolerance. The self-reported food intolerance rate was 3.68% (61/1656) and 5.23% (51/976) in the two age groups, respectively. Age, parental history of allergy and father's educational level (OR was 2.452, 1.482 and 2.598, respectively, P < 0.01) were the risk factors of food hypersensitivity; within two weeks of sickness (OR = 1.267, P < 0.05) was the risk factor of food intolerance.

CONCLUSIONInfancy was the most vulnerable period of life of getting allergy, therefore, it is necessary for all infants to prevent allergy through a variety of effective strategies.
