Clinical features of coronavirus disease 2019 in children aged <18 years in Jiangxi, China: an analysis of 23 cases / 中国当代儿科杂志

OBJECTIVE@#To study the clinical features of coronavirus disease 2019 (COVID-19) in children aged <18 years.@*METHODS@#A retrospective analysis was performed from the medical data of 23 children, aged from 3 months to 17 years and 8 months, who were diagnosed with COVID-19 in Jiangxi, China from January 21 to February 29, 2020.@*RESULTS@#Of the 23 children with COVID-19, 17 had family aggregation. Three children (13%) had asymptomatic infection, 6 (26%) had mild type, and 14 (61%) had common type. Among these 23 children, 16 (70%) had fever, 11 (48%) had cough, 8 (35%) had fever and cough, and 8 (35%) had wet rales in the lungs. The period from disease onset or the first nucleic acid-positive detection of SARS-CoV-2 to the virus nucleic acid negative conversion was 6-24 days (median 12 days). Of the 23 children, 3 had a reduction in total leukocyte count, 2 had a reduction in lymphocytes, 2 had an increase in C-reactive protein, and 2 had an increase in D-dimer. Abnormal pulmonary CT findings were observed in 12 children, among whom 9 had patchy ground-glass opacities in both lungs. All 23 children received antiviral therapy and were recovered.@*CONCLUSIONS@#COVID-19 in children aged <18 years often occurs with family aggregation, with no specific clinical manifestation and laboratory examination results. Most of these children have mild symptoms and a good prognosis. Epidemiological history is of particular importance in the diagnosis of COVID-19 in children aged <18 years.

Knowledge, attitude and practice on schistosomiasis control of chronic schistosomiasis patients in Poyang Lake area,Nanchang City / 中国血吸虫病防治杂志

Objective To understand the present situation of the chronic schistosomiasis patients'knowledge,attitude and practice on schistosomiasis control in Nanchang City. Methods The knowledge,attitude and values on schistosomiasis control of 523 chronic schistosomiasis patients in Nanchang County,Jinxian County and Xinjian District in the Poyang Lake District were investigated with questionnaires. And the accuracy rates of the knowledge,attitude and practice among the patient groups of different counties,genders,age groups,occupations and educational levels were analyzed. Results The accuracy rates of the knowledge,attitude and practice of patients on schistosomiasis control were 95.76%,82.80%,and 81.73% in Nanchang County;91.37%,93.32%,and 76.48%in Jinxian County;88.25%,67.56%,and 49.40%in Xinjian District. In the accuracy rates of knowledge,attitude and practice,the differences among the three counties (districts) were statistically significant (χ2=57.511-301.378,all P<0.05). Conclusions The accuracy rates of chronic schistosomiasis patients'attitude and prac-tice on schistosomiasis control in Nanchang City remain low. Therefore,the intensity of attitude and practice intervention should be strengthened in the Poyang Lake District in order to enhance the self-protection awareness of the patients.

Levels of atrial natriuretic peptide in umbilical cord blood of high risk neonates / 中国当代儿科杂志

<p><b>OBJECTIVE</b>Atrial natriuretic peptide (ANP) is a cardiac hormone with many biological effects. Hypersecretion may lead to hyponatremia. This study examined the umbilical ANP levels in high risk neonates.</p><p><b>METHODS</b>A total of 117 high risk neonates born between June, 2004 and June, 2005 were divided into Simple asphyxia and Normal score groups according to their Apgar's scores. The Simple asphyxia group was subdivided into Mild (n=20) and Severe asphyxia groups (n=17), and the Normal score group was subdivided into Infection (n=25) and Non-infection groups (n=55). Forty normal neonates were used as the Control group. The samples of umbilical cord blood were collected at delivery and the umbilical ANP levels were measured by radioimmunoassay. Meanwhile the sodium levels in the peripheral vein were measured.</p><p><b>RESULTS</b>The mean umbilical ANP levels in high risk neonates were significantly higher than those in the normal neonates. A more significant increase of the umbilical ANP level was observed in premature infants (1.46 +/- 0.39 ng/mL), and neonates with serious infection (1.16 +/- 0.35 ng/mL) and with severe asphyxia (2.12 +/- 0.46 ng/mL) compared with the normal neonates (0.62 +/- 0.33 ng/mL; P < 0.01). The serum sodium level was negatively correlated with the umbilical ANP level (r=-0.99, P < 0.01).</p><p><b>CONCLUSIONS</b>The umbilical ANP levels increased significantly in the high risk neonates, suggesting high risk neonates are susceptible to hyponatremia.</p>

Changes of Atrial Natriuretic Peptide and Parathyroid Hormone in Umbilical Cord Blood of Newborn Infants with Intrauterine Growth Retardation and Their Relationships with Electrolytic / 实用儿科临床杂志

Objective To explore the changes of atrial natriuretic peptide(ANP)and parathyroid hormone(PTH)in umbilical cord blood of newborn infants with intrauterine growth retardation(IUGR)and their relationships with electrolytic.Methods A total of 71 IUGR infants borned between Jan.2006 and Aug.2007 were enrolled in this study.Another 40 normal appropriate for gestational age neonates were selected as control group.The study group were divided into 2 groups:mature IUGR group(n=29)and premature IUGR group(n=42).The samples of umbilical cord blood of every group were collected at the time of delivery,and ANP,PTH levels in umbilical cord blood were mea-sured by radioimmunoassay.The sodium,calcium levels in their peripheral vein were measured simultaneously.Results 1.Compared with control group[(0.78?0.42)?g/L],the ANP levels of premature IUGR group[(1.26?0.47)?g/L] and the mature IUGR group[(1.09?0.51)?g/L] were significantly increased(t=5.98,2.76 Pa0.05).The calcium levels of the premature IUGR group[(1.85?0.37)mmol/L]significantly decreased(t=1.93 P0.05)compared with control group [(2.02?0.44)mmol/L].3.The serum sodium level was negatively correlated with the umbilical ANP level(r=-0.93 P
