RESUMO
Objective:To analyze the impact of COVID-19 on the number of hospitalization and the disease spectrum of children′s hospitals in China, so as to provide scientific basis for improving the epidemic response policy of children′s hospitals and restoring hospital operations.Methods:Discharged patients from 27 children′s hospitals from January 1, 2019, to December 31, 2020, were selected from the FUTang Updating medical Records(FUTURE) Database. The ratio of discharge number in 2020 to that in 2019 was calculated. Age groups, disease types, and discharge months were further divided to calculate the ratio of discharge numbers under different conditions.Results:The total number of discharged patients in 2020 was 76.76% of the total number in 2019. In terms of discharge time, the ratio rose slowly from the lowest values in February and March, and reached about 90% of the same period of 2019 at the end of 2020. In terms of age, the biggest change in the discharge number was among children aged 1-3 years, which was 71.87% in 2019. In terms of disease classifications, respiratory diseases changed the most in the number of discharged patients in 2020, accounting for 56.03% of that in 2019. The top five hospitalized diseases of children did not change, while the other ranks changed slightly.Conclusions:COVID-19 has a huge and lasting impact on the number of hospitalizations in children′s hospitals, and the hospitals should develop multiple approaches such as online medical care to cope with the long-term negative impact of the pandemic.
RESUMO
Objective:To explore the variation of hospitalization expenses and its influencing factors under the same main diagnostic disease(children′s unilateral inguinal hernia), and group them based on regression tree model, so as to provide reference for diagnosis-related groups(DRG) grouping of the disease.Methods:The data of the first page of medical records with unilateral inguinal hernia(ICD-10 coding K40.3 and K40.9)as the main diagnosis discharged from a children′s special hospital from 2016 to 2018 were extracted. With hospitalization expenses as the outcome variable and gender, age, operation type, length of hospital stay and complications as the predictive variables, a regression tree model was constructed to classify the children into subgroups.Results:The regression tree model showed that the variables that had a significant impact on the total hospitalization costs were the length of hospital stay, operation type and complications. Age and gender had no significant impact on the hospitalization expenses. According to these three significant variables, the children were divided into five subgroups and the median hospitalization expenses were 1 190.8, 6 387.2, 7 037.7, 11 413.7, and 18 499.1, respectively. Except that the coefficient of variation of hospitalization expenses in group 1 was greater than 1, the coefficient of variation of the other four groups were≤0.5.Conclusions:Children with unilateral inguinal hernia can be divided into groups according to the length of hospital stay, operation type and complications, and the grouping results are relatively reasonable.
RESUMO
Objective:To analyze the gastroscopy treatment technology in a Children′s Medical Center based on the diagnosis-related groups(DRG) and put forward suggestions for resource optimization.Methods:The data of the front pages of medical records of 22 medical institutions in a Children′s Medical Center in 2018 were divided into DRG groups. The patients in gastroscope treatment operation group(GK3)were selected, and the disease diagnosis, operation and payment methods of the patients in this group were analyzed.Results:Of the 22 medical institutions, 16 had GK3 group cases, and the number of cases was significantly different, ranging from 2 to 917. Among them, the institution with code M was characterized by multiple endoscopic treatment of esophageal stricture, but most other institutions rarely carried out the treatment of esophageal stricture. In GK3 group, the main payment method of children in Institution M with the highest constituent ratio was at one′s own expense, followed by non-local medical insurance. The main payment type of O and P institutions with the second and third constituent ratio was local medical insurance.Conclusions:The gap of the technology of gastroscopy in the treatment of esophageal stricture is large in all institutions. The high-quality medical resources can be sunk through the construction of pediatric medical alliance, and the gap between the regional medical technology can be continuously leveled.
RESUMO
Objective@#To evaluate the endothelial function in obstructive sleep apnea syndrome(OSAS) children and to identify related factors of endothelial dysfunction.@*Methods@#This was a cross-sectional study. Children with habitual snoring (snoring ≥3 nights per week) admitted to the ward of otolaryngology, head and neck surgery, Beijing Children′s Hospital were recruited to this study between 1st June 2015 and 1st March 2016. All children aged 3 to 11 years and of them 245 were boys and 110 were girls. All subjects underwent an overnight polysomnography (PSG), as well as endothelial function testing. All subjects were grouped into primary snoring (PS) and OSAS group according to the obstructive apnea hypopnea index (OAHI). T test or Wilcoxon test were used to compare the differences in PSG results between the two groups, and univariate and multivariate correlation analyses were used to explore the relevant factors affecting the endothelial function.@*Results@#A total of 355 subjects were enrolled and 248 had OSAS, and 107 had PS. There were no significant differences in age, gender and body mass index (BMI) Z-score between the two groups (all P>0.05). OSAS group had higher OAHI, oxgen desaturation index and respiratory related arousal index (5.2 (2.2, 13.2) vs. 0.4 (0.1, 0.7), 4.1 (2.0, 13.1) vs. 0.5 (0.1, 1.0), 2.5 (1.0, 4.8) vs. 0.4 (0.1, 0.9), Z=-14.957, -11.790, -10.378, all P<0.01), and lower minimum oxygen saturation and reactive hyperemia index (RHI) than those of PS (0.89 (0.85, 0.92) vs. 0.94 (0.91, 0.95), 1.2±0.2 vs. 1.1±0.1, Z=-9.337, t=5.354, P<0.01). Univariate regression analysis showed that RHI was linearly correlated with age (parameter estimate=0.017, P<0.01), gender (parameter estimate=0.065, P<0.01), OAHI (parameter estimate=-0.023, P<0.01), oxygen desaturation index (parameter estimate=-0.019, P<0.01), respiratory related arousal index (parameter estimate=-0.031, P<0.01), and oxygen saturation nadir (parameter estimate=0.067, P=0.045). The relationship between BMI Z-score and RHI was quadratic. Multivariate regression analysis showed that age (parameter estimate=0.015, P<0.01), BMI Z-score (parameter estimate=0.040, P<0.01), BMI Z-score quadratic form (parameter estimate=-0.010, P<0.01), respiratory related arousal index (parameter estimate=-0.020, P<0.01) were independently correlated with RHI.@*Conclusions@#Children with OSAS have significant endothelial dysfunction compared with PS. Frequent arousals due to obstructive respiratory events during sleep may be a candidate risk factor for endothelial dysfunction in children with OSAS.
RESUMO
Objective@#To investigate the sleep quality of children in Beijing and to analyze the related factors.@*Methods@#The data were collected from the survey of 3-14 years old children in 7 urban districts of Beijing in 2015. By using multi-stage stratified cluster random sampling method, 26 kindergartens and primary and secondary schools in 7 districts and counties, including Xicheng, Chaoyang, Changping, Shunyi, Fangshan, Huairou and Mentougou, were randomly selected, with a total of 11 420 children. Children′s sleep status was investigated with Children′s Sleep Questionnaire (PSQ), and the proportion of children with sleep quality problems when the PSQ score was greater than 7. Various sleep related factors were investigated with self-made questionnaire. A multilevel model was used to analyze the relationship between PSQ score and related factors.@*Results@#The average PSQ score of the children was 3.60±2.69. The proportion of children with sleep quality problems was 8.87%(816/9 198). Multilevel model analysis showed that the younger the children, the higher the PSQ score (<6 years old vs. 6~12 years old vs. >12 years old: 3.94±2.58 vs. 3.58±2.66 vs. 3.30±2.84, F=33.015, P<0.001); male PSQ score higher than female (3.89±2.75 vs. 3.30±2.60, t=10.560, P<0.001); and snoring, obesity, father/mother snoring, playing games before bed, surfing the internet, eating and other factors were statistically related to PSQ.@*Conclusions@#Sleep quality of children in Beijing should not be neglected, especially preschool children with high PSQ scores. Parents should pay attention to children′s snoring problems and try to reduce some pre-sleep behaviors that may affect sleep quality.
RESUMO
Objective@#To investigate the snoring status and related family factors of children from 3 to 14 years old in Beijing.@*Methods@#From May to July, 2015, data of children from 3 to 14 years old were obtained from a status survey from 7 districts(Xicheng, Chaoyang, Changping, Shunyi, Fangshan, Huairou and Mentougou) in Beijing. A total of 11 420 children from 25 primary and middle schools were randomly selected. Pediatric Sleep Questionnaire (PSQ) and a self-administered questionnaire were carried out for the adopted children. Self-administered questionnaire included the snoring related family factors. Logistic regression was used to estimate the odd ratio(OR) with 95% confidence intervals for variables.@*Results@#A total of 9 198 children meet the inclusion criteria and are analyzed in the study, of whom 901 (9.80%) were found with snoring behavior. The incidence of boys is higher than girls. Obese children take higher risk of snoring. Compared with younger children (≤6 years old), older children (≥12 years old) have a significantly lower risk of snoring (OR=0.464, 95%CI 0.368-0.585). There is no statistical association between full-term infants, infant feeding pattern, parental cigarette smoking and child snoring.The children with family history of snoring have a significantly higher risk of snoring occurrence. The educational background of mother is statistically related to children snoring (OR=1.241, 95%CI 1.058-1.457).@*Conclusions@#The incidence of children snoring in Beijing is 9.80%, male gender, obesity, and young age are all risk factors for children snoring. There is a significantly statistical relationship between snoring and related family factors, such as family snoring history and education experience.
RESUMO
Logistic regression has been recognized as a commonly used method in epidemiological studies. However, in practice, many people only consider 'data’ rather than 'study design’ as important issue when working on the analysis, which may easily lead to some misleading results and conclusions. Based on the purpose of observational research during the design of the study, this paper discusses the specific ideas in logistic regression analysis, and provides references for the practical application when logistic regression method is used.
RESUMO
Objective To propose on and improve direct settlements by medical insurance offices and hospital systems in their processing of medical treatment in allopatry (MTA), by analyzing such data as the homepages of medical records of such inpatients at a tertiary cancer hospital with their medical expenses settled directly. Methods Data of 6 379 MTA inpatients with direct settlements of in-hospital fees from April 2017 to March 2018 were included in this study. Such data were used to identify the change trend of their case counts and their regional distribution, and analyzed with hierarchical clustering to calculate the settlement counts of various provinces. Results Analyses found that the total cases of such patients remained stable at the hospital, yet the cases of direct settlement rose from five to 1 263, and the proportion of direct settlement among all MTA inpatients rose month by month from 0.14% to 29.26%. Most of MTA inpatients come from Hebei, Shandong, Inner Mongolia and Shanxi provinces in turn, yet the direct settlement counts and hospitalization case trends appear different. Clustering results indicate Hebei as the type-1 province with the highest proportion of direct settlement inpatients, accounting for 30. 41% ;Shandong, Inner Mongolia and Shanxi as the type-2 provinces, accounting for 15. 05% , 13. 45% and 11.00% respectively; Liaoning, Henan and Heilongjiang as the type-3 provinces, accounting for 6.79% , 4.81% and 4.42% respectively; while the rest provinces as the type-4, accounting for less than 3%. Conclusions Regional distribution varies distinctively among such inpatients, and the number of these inpatients keeps rising stably. In such circumstances, hospitals are recommended to enhance their management in strengthening medical insurance audit systems, speeding up settlement, and building regional medical alliances.
RESUMO
Objective To evaluate the efficacy and safety of Chushizhiyang ointment for the treatment of mild atopic dermatitis in infants.Methods A multicenter,randomized,open,active-controlled clinical trial was conducted.A total of 204 infants with atopic dermatitis were enrolled and randomly divided into 2 groups to be topically treated with Chushizhiyang ointment (test group,n =103) and hydrocortisone butyrate cream (control group,n =101),respectively,for 2 weeks.The improvement of eczema area and severity index (EASI) scores and quality of life was evaluated at 7 days and 14 days after the treatment,so was the incidence of adverse events and adverse reactions.Results Ninety-eight infants in the test group and 101 in the control group were included in the full analysis set,which revealed that the disease severity significantly decreased after the treatment in both groups.The EASI scores at the baseline and on days 7 and 14 were 2.47 ± 4.04,0.92 ± 1.25 and 0.39 ± 1.04 respectively in the test group,as well as 2.13 ± 2.01,0.85 ± 1.58 and 0.45 ± 1.65 respectively in the control group.Furthermore,the test group and control group both showed that EASI scores on days 7 and 14 significantly decreased compared with those at the baseline (the test group:T =-1 666,-1 793,respectively,both P ＜ 0.001;the control group:T =-1 951,-1 941,respectively,both P ＜ 0.001).No significant differences in EASI scores at the baseline or on days 7 and 14 were observed between the test group and control group (all P ＞ 0.05).The response rates in the test group and control group were 47.96％ (47/98) and 55.44％ (56/101) respectively on day 7,as well as 79.59％ (78/98) and 84.16％ (85/101) respectively on day 14,and there were also no significant differences between the two groups (both P ＞ 0.05).The adverse reactions mainly manifested as erythema,itching and scaling in the test group,as well as hypopigmentation,telangiectasia,scaling and hyperpigmentation in the control group.No significant difference in the incidence of adverse events was found between the test group (2.9％,3/103) and control group (6.9％,7/101).Conclusion Chushizhiyang ointment shows definite efficacy for mild atopic dermatitis in infants with good safety and tolerability,and can be a teatment option for mild atopic dermatitis in infants.
RESUMO
Objective To evaluate the application value of the micro movement sensitive mattress sleep monitoring system(MSMSMS) in the diagnosis of children with obstructive sleep apnea syndrome (OSAS).Methods One hundred and twenty-nine children aged from 3 to 14 years who visited the sleep center of Beijing Children's Hospital Affiliated to Capital Medical University from June 2013 to June 2015 due to sleep snoring were enrolled.Children with acute respiratory infection,cranial facial abnormalities,chronic lung diseases and neuromuscular diseases were excluded.According to the criteria,36 children were diagnosed as OSAS with average age of (7.3 ± 2.5) years,including 28 males and 8 females.Ninety-three non-OSAS children were recruited with average age of (6.3 ± 2.3) years,including 61 males and 32 females.Subjects were monitored with polysomnography(PSG) and MSMSMS simultaneously.Apnea/hypopnea index (AHI) ＞ 5 or obstructive apnea index (OAI) ＞ 1 were used to define whether OSAS existed.The consistency between MSMSMS and PSG in the diagnosis of OSAS and the determination of sleep efficiency were compared.Results The Kappa consistency coefficient of MSMSMS and PSG in the diagnosis of OSAS was 0.70(95％ CI:0.57-0.84),Z =7.99,P ＜ 0.000 1,which indicated the consistency between PSG and MSMSMS was good.The consistency of sleep efficiency of MSMSMS and PSG were compared.Bland-Altman results showed that there were 3％ (5/129 cases)points out of 95％ consistency bound and the interclass correlation coefficient (ICC) was 0.69 which indicated the consistency of 2 methods was good in determination of sleep efficiency.MSMSMS was able to detect respiratory event that was associated with sub-cortical arousals with no electroencephalogram arousal or blood oxygen reduction.Conclusions There is an adequate consistency between MSMSMS and PSG in the diagnosis of children with OSAS and determination of sleep efficiency.The MSMSMS has an advantage in detection of sub-cortical arousals and respiratory event.
RESUMO
Objective To summarize the clinical features and technical key points on brain death during decision-made process in children with suspected brain death.Methods Twenty-four coma children with Glasgow coma scale score 3 and no spontaneous respiration were collected from May 2015 to February 2017 in Beijing Children's Hospital,Capital Medical University to make the brain death determination.All children received at least one confirmatory test.According to the Chinese standards for determining brain death (pediatric),all patients were divided into brain death group and non-compliance group.The clinical features were analyzed.The sensitivity,specificity,false positive rate and false negative rate of electroencephalogram (EEG),short latency somatosensory evoked potential (SLSEP) and transcranial Doppler sonography (TCD) were calculated.Results Among these 24 cases,there were 16 males and 8 females,aged 5.6 (2.0,8.8) years old.Ten cases met the criteria of brain death.Twelve (50％,12/24 cases) cases received autonomic breathing test.A total of 25 tests were conducted,of which 21 were successful.The completion rates of EEG,TCD and SLSEP were 100.0％ (24/24 cases),83.3 ％ (20/24 cases) and 54.2％ (13/24 cases),respectively.EEG had the highest sensitivity (100％) and specificity (79％).SLSEP had good sensitivity (100％),but the specificity was only 40％.The combination of EEG with SLSEP had the highest specificity and sensitivity,both of which were 100％,and the false positive rate and false negative rate were 0.Conclusions The key to determine brain death successfully is to make adequate preparations,to receive formal training and to apply standard operation.In the determination of brain death in children,EEG has a good sensitivity and specificity in single confirmation test,which is the priority item.The combination of EEG with SLSEP is the most advantageous.
RESUMO
Objective To evaluate the clinical application of pulmonary high-resolution CT (HRCT) and radionuclide pulmonary V/Q scan in pediatric patients with bronchiolitis obliterans (BO).Methods From February 2005 to April 2011,30 BO pediatric patients (18 males,12 females,age range:7 months-14 years) in Beijing Children's Hospital Affiliated to Capital Medical University were recruited for pulmonary HRCT and radionuclide pulmonary V/Q scan.Kappa test was used to describe the consistency between "Mosaic perfusion pattern" in pulmonary HRCT and radionuclide pulmonary ventilation abnormalities.Results "Mosaic perfusion patterns" in pulmonary HRCT were showed in 30 cases (100％).Ventilation defects were found in 27 cases (90.0％) and perfusion defects in 25 cases (83.3％).The Kappa value between "Mosaic perfusion pattern" in pulmonary HRCT and pulmonary ventilation defects was 0.201 (0.1340.268),which was slightly higher than that between "Mosaic perfusion pattern" in pulmonary HRCT and pulmonary perfusion defects (0.147 (0.061-0.233)),but there was no statistical difference.Conclusions " Mosaic perfusion pattern" in pulmonary HRCT cannot distinguish between pulmonary ventilation and perfusion abnormalities.V/Q scan could be a useful tool for BO.

RESUMO
Traditional Chinese medicine (TCM) safety assessment is an important content of post-marketing Chinese herbal medicine assessment and the primary question. It includes safety monitoring and safety evaluation. China has established the elementary system for the TCM safety monitoring, but did few things on safety evaluation. People have knew that the methods of pharmacoepidemiology have good practicability on drug safety assessment in recent years. This article analyzed three methods of pharmacoepidemiology used in post-marketing Chinese herbal medicine safety assessment. There are three examples that may give some suggestions to fellow doctors working for safety monitoring and evaluation of TCM.

Objective:To investigate the role of transforming growth factor β1 (TGFβ1) in the development of Helicobacter pylori ( H. pylori)-associated non-metaplastic atrophic gastritis. Methods:The expressions of TGFβ1, CD68 and smooth muscle actin(SMA) were detected immunohistochemically in 10 patients with mild non-atrophic gastritis, 30 patients with mild non-metaplastic atrophic gastritis, and 32 patients with severe non-metaplastic atrophic gastritis having H. pylori infecion. Meanwhile, three cases of mild non-atrophic gastritis and 4 cases of severe non-metaplastic atrophic gastritis were observed with electron microscope. Results: The count of TGFβ1 positive cells per high-power field (HPF) in severenon-metaplastic atrophic gastritis group (53±22 ) was significantly higher than that in mild non-atrophic gastritis group(22±/HPF) and mild non-atrophic gastritis group(0-3/HPF, P＜0.01). The count of CD68 positive cells in severe non-metaplastic atrophic gastritis group (23±7/HPF) was significantly higher than that in mild non-atrophic gastritis group (13±/HPF) and mild non-atrophic gastritis group (0-3/HPF, P＜0. 01). Correlation analysis showed that the expressions of TGFβ1 and CD68 had a moderate correlation in each group ( r = 0. 634, P＜ 0. 01; r = 0. 699, P＜ 0. 01). Compared with mild non-atrophic gastritis, SMA-positive myofibroblasts and smooth muscle cells in the lamina propria increased in mild and severe non-metaplastic atrophic gastritis. Ultrastructurally, the proliferation of fibroblasts in gastric lamina propria was observed in mild non-atrophic gastritis, while the proliferation of fibroblasts and presence of myofibroblasts could be observed in mild non-metaplastic atrophic gastritis, and there was a parallel phenomenon between myofibroblasts and fibroblasts, as well as smooth muscle cells.Conclusion: Our findings indicate that TGFβ1 expression increases with severity of H. pylori-associated non-metaplastic atrophic gastritis, suggesting that TGFβ1 might play an important role in the development of non-metaplastic atrophic gastritis.
