ABSTRACT
Objective:To prevent the occurrence of children′s unintentional injuries, clinical characteristics were analyzed for 1 379 children hospitalized for unintentional injuries over a 5-year period at the First Affiliated Hospital of Xiamen University.Methods:We searched the First Affiliated Hospital of Xiamen University Pediatric Refined Management Database for all cases of children aged 0-14 years who were hospitalized for unintentional injuries from January 1, 2015 to December 31, 2019.Descriptive statistics were calculated for age, gender, season of injury, location of residence, education level of the child′s parents/guardians, injury etiology and outcome, and cost of treatment.Results:Of 1 379 cases, 894 children(64.8%) were boys and 485(35.2%) were girls.The majority of cases were 1-5 years old(61.6%, n=849). The top three causes of unintentional injuries were foreign bodies(38.1%, n=526), falls(27.0%, n=372), and burns(17.1%, n=236). Children′s unintentional injuries occurred most frequently during the summer(29.0%). More children came from rural locations(56.3%, n=777). Approximately half of the parents/guardians had attained an education level of junior high school or below(50.5%, n=696). There were 47 cases(3.4%) resulting in death or permanent injury and 292 cases(21.2%) resulting in disability.Children injured in traffic accidents had the longest average length of hospital stay [11(7, 18)d] and incurred the highest healthcare costs per case[11 130.32(5 389.69, 24 216.90)RMB]. Conclusion:Children′s unintentional injuries are concentrated among rural boys aged 1-5 years, foreign bodies are the most common cause of unintentional injuries.Children from families with low parental/guardian education levels may be at heightened risk of unintentional injuries.
ABSTRACT
Objective:To compare the clinical characteristics of Mycoplasma pneumoniae pneumonia and adenoviral pneumonia in children. Methods:Clinical data of 151 children with pneumonia admitted to our hospital from January 2019 to June 2019 were retrospectively analyzed, including 106 cases of Mycoplasma pneumoniae pneumonia (MP group) and 45 cases of adenoviral pneumonia (ADV group). The general conditions, clinical manifestations, laboratory results, pulmonary imaging, proportion of severe cases, respiratory support style and length of hospital stay were compared between two groups. Results:The MP group had shorter fever time compared to the ADV group ( t=15.910, P<0.01); and the maximum temperature in the MP group was lower than the ADV group ( Z=3.561, P<0.01). In the comparison of shortness of breath, wet rales in the lungs, tri-concave sign, hypoxemia, the differences were all significant between two groups (χ 2=11.203, 6.807, 36.746, 21.177, all P<0.01). The WBC in the MP group was lower than that in the ADV group ( t=33.960, P<0.01); the PCT, IL-6, LDH and 25-(OH) D 3 levels in the MP group were lower than those in the ADV group ( Z=5.986, 3.146, 4.203, 2.094, all P<0.05); while there was no significant difference in CRP levels between two groups ( Z=1.360, P>0.05). Pulmonary imaging in the MP group mainly involved unilateral lung, and the ADV group mainly involved bilateral lungs (χ 2=27.055, P<0.01). There was no significant difference in pulmonary patchy exudation between two groups(χ 2=0.298, P>0.05). There were 30 patients (28.3%) with severe pneumonia in MP group and 33 patients (73.3%) in the ADV group ( t=26.345, P<0.01). Twelve patients (11.3%) in the MP group were given non-invasive respiratory support, 1 patient (0.9%) was given invasive respiratory support; while 31 patients (68.9%) were given non-invasive respiratory support in the ADV group, and 5 patients (11.1%) were given invasive respiratory support (χ 2=66.439, P<0.01). The MP group had shorter hospital stays than ADV group ( t=31.014, P<0.01). Conclusion:The conditions of disease are more severe, and length of hospital stay is longer in children with adenoviral pneumonia than those with Mycoplasma pneumoniae pneumonia.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the effect of weight-loss for overweight or obese population under the health management programs, and to provide evidence for the development of safe and effective weight-loss programs.</p><p><b>METHODS</b>738 participants who resided in Beijing longer than one year, under 22 to 55 years of age, with BMI≥24 kg/m(2) and without organic diseases were voluntarily recruited, from September 1(st) to October 15(th) 2013. All the participants were randomly divided into general management group or under health management group, in which all the subjects received intervention measures for 6 months. Anthropometry and body composition were measured at baseline and 6 months for all the subjects. Weight-loss effect from the health management programs was evaluated through analyzing the changes on weight and body fat.</p><p><b>RESULTS</b>618 participants completed the follow-up process, including 321 in the general management group and 297 in the health management group. 6 months after the intervention process, values of weight and body fat rate in the two groups appeared both significantly lower than that at the baseline levels. Difference before and after the intervention program was statistically significant (P<0.001). However, the differences of those with reduction value as 2.19 kg or 2.19% among health management group were higher than that in the general management group, which were 0.97 kg and 1.28% respectively, with difference statistically significant (P<0.001). The effective rate of 24.2% loss-weight and the 52.5% losing rate on body fat among the health management group were both higher than 11.8% and 34.3%, seen in the general management group, respectively, with difference statistically significant (P<0.001).</p><p><b>CONCLUSION</b>The healthy management programs could effectively control the weight and body fate rate among the overweight or obese adults.</p>

Objective To study the effects of Bacillus Calmette-Guerin (BCG) intervention on the expression of stem cell factor (SCF) in asthma. Methods Kunming mice were randomly divided into asthmatic group, BCG group and control group of ten mice each group. Mice were sensitized and challenged with ovalbumin (OVA) to establish asthmatic model. After twenty-four hours of last challenge, eosinophils (EOS) were counted in the lung tissue and bronchoaveolar lavage fluid (BALF). The level of SCF in BALF was determined by enzyme-linked immunosorbent assay. The expression of SCF protein in lung tis-sue was measured by immunohistochemistry technique and computerized image analysis system. Results The number of EOS in lung tissue was (10.67±1.94)/HP, (6.40±1.55)/HP and (0.37±0.33)/HP in asthmatic, BCG and control group respectively. The number of EOS in BALF was (7.58 ± 1.30) × 107/L, (3.78 ± 1.15) × 107/L and 0 in asthmatic, BCG and control group respectively. The difference between each group was statistically significant (P0.05). In asth-matic group, the expression of SCF in lung was positively correlated with the number of EOS (P<0.05). Conclusions BCG treat-ment can markedly decrease the airway inflammation in asthmatic mice. BCG cannot inhibit the expression of SCF in asthma.
ABSTRACT
Objective To study changes of AMPA receptors expression in nucleus accumbens and hypothalamus of methamphetamine dependent rats,and the therapeutical effect of rhynchophylline.Methods SPF male rata were randomly divided into normal control group,model group of methamphetamine,low dose of rhynchophylline group and high dose of rhynchophylline group(n=8 in each group).Experiment of conditioned place preference(CPP)was used to build the model of methamphetamine dependent rata.Western blotting was used to examine the changes of GluR2/3 subunits expression.The time of staying in drug-paired compartment of rats was used independent-samples t test to gather statistics,and the photodensity of proteinum strap was used One-Way ANOVA to gather statistics.Results Compare with rats in normal control group(the time of staying in drug-paired compartment of rats was(383.00±38.20)s),the rats produced CPP after treated with methamphetamine(the time of staying in drug-paired compartment of rats was(536.20±57.49)s),and low(30mg/kg) and high (60 ms/kg)dose of rhynchophylline(the time of staying in drug-paired compartment of rats were(299.80±15.96)s and(189.40±59.02)s)both could eliminate CPP effect.Compare with rats in normal control group (the ratio of value of average gray scale were(0.54±0.04)INT·mm~2 and (0.70±0.04)INT·mm~2),GluR2/3 subunits expression in nucleus aecumbens increased significantly in model group(the ratio of value of average gray seale was(0.89±0.03)INT·mm~2)and low dose of rhynchophylline group(the ratio of value of average gray seale was (0.93±0.03)INT·mm~2,P<0.01),which decreased significantly in hypothalamus(the ratio of value of average gray scale were (0.53±0.03)INT·mm~2 and (0.52±0.02)INT·mm~2,P<0.01).But GluR2/3 subunits expression in nucleus accumbens and hypothalamus of rats in high dose of rhynchophylline group(the ratio of value of average gray scale were (0.57±0.06)INT·mm~2 and (0.65±0.01)INT·mm~2) just liked the expression of normal control group(P>0.05).Conclusion GluR2/3 subunits expression of methamphetamine-induced CPP rats increased in nucleus accumbens but decreased in hypothalamus.High dose of rhynchophylline can reverse such changes and rebound the expression to normal level.
