Objective: To analyze the disease burden and trend of attention deficit hyperactivity disorder (ADHD) in China from 1990 to 2019, so as to provide the basic theoretical basis for the health administrative departments to formulate policies. Methods: Using the 2019 Global Burden of Disease Database, the incidence, prevalence and disability adjusted life year (DALY) rates of ADHD were analyzed for both sex and different age groups, and the trends of ADHD were predicted. Results: In 2019, the incidence, prevalence and DALY rate of ADHD in China were 70.41/100 000, 1 546.15/100 000 and 18.87/100 000 respectively. Compared with 1990, the rates decreased by 27.30%, 25.35% and 55.80% respectively, and these rates of females were lower than those of males. In 2019, the incidence rate of ADHD was the highest in the age group 5-9 years old (837.76/100 000), while the highest prevalence and DALY rates were found in ages groups of 10-14 years old (5 740.47/100 000 and 70.49/100 000). The results of the Joinpoint regression model showed that the incidence, prevalence and DALY rate had a downward trend from 1990 to 2019. The AAPC was -1.35%, -1.16% and -1.16%, respectively, with a statistically significant difference ( P <0.05). The prediction results of grey prediction model GM (1,1) indicated that the incidence and prevalence rate of ADHD in China would decline from 2020 to 2030. Conclusion The burden of ADHD in China showed a decreasing trend from 1990 to 2019, indicating that the prevention and treatment effect of ADHD in children and adolescents of China was effective. China should take active preventive measures to reduce the burden of ADHD in children and adolescents.

Objective:To find out the occurrence of anxiety and depressive symptoms, and the major risk factors, and the participation rate, as well as the experience of medical personnel who are involved in the intervention.Methods:Since January 2018, a pilot intervention had been carried out on pregnant women registered in the antenatal clinic. The Generalized Anxiety Disorder Scale and the Patient Health Questionnaires were used as screening tools for anxiety and depression symptoms, and risk factors were screened too. Interventions were carried out on the psychological moderate and high risk women by obstetric medical staff and mental health personnel. A qualitative interview was conducted on the intervention providers.Results:A total of 9 488 pregnant women were included, and the positive rate of moderate anxiety symptoms was 3.0%, the positive rate of severe anxiety symptoms was 1.4%; the positive rate of moderate depression symptoms was 18.1%, and the positive rate of severe depressive symptoms was 5.2%; the comorbidity rate of anxiety and depression symptoms was 3.4%. The first three risk factors for pregnant women with anxiety symptoms were: once had premenstrual stress symptom, excessive fear of fetal growth, previous abnormal maternal history; the first three risk factors for pregnant women with depressive symptoms: once had premenstrual stress symptom, previous abnormal maternal history, this pregnancy was cherished; the first three risk factors for pregnant women with moderate and above anxiety combined with depression were: once had premenstrual stress symptom, excessive fear of fetal growth, and fear the delivery process is not successful. Among the psychological moderate risk pregnant women, 19.1% participated in the midwife joint counselor clinic, and 1.7% participated in the obstetrician joint psychological specialist nurse clinic, 2.2% of the pregnant women with high risk participated in the psychological multidisciplinary consultation, and 1.7% referred to the psychiatric department. From the interviews, providers believed that it was necessary to further strengthen the ability of psychological intervention capacity, and the psychological screening tools needed to be improved, and the problems sought by pregnant women involved in physical, psychological and social aspects, and the influence of pregnant women's treatment compliance included multiple factors.Conclusions:The psychological health care service during pregnancy was feasible, but the screening scales needed further examination. The mental health care ability of obstetric medical staff needed to be strengthened, and the compliance of pregnant women with mental health services needed to be improved.

Objective: To summarize the clinical features of 7 rare cases of hemolytic disease of newborn (HDN), and to improve the understanding of rare HDN. Methods: Data of clinical information, laboratory findings, treatments and outcomes were collected and analyzed for four cases with HDN due to anti-M, two cases due to anti-Kidd, and one case due to anti-Duffy. All of them were admitted to the Department of Neonatology, Beijing Children's Hospital Affiliated to Capital Medial University from July 2007 to June 2017. Results: Among the four MN hemolytic babies, two were males and two were females. Jaundice was found in three cases. Two cases had hyperbilirubinemia, one of them had severe hyperbilirubinemia. All the four cases developed anemia, including severe anemia in three cases. Two cases of Kidd hemolytic disease and 1 case of Duffy hemolytic disease had jaundice and anemia, but did not reach the level of severe hyperbilirubinemia and severe anemia. MN hemolytic disease babies got negative results in direct antiglobulin test, whereas the Kidd and Duffy hemolytic disease babies had positive findings in direct antiglobulin test. None of the babies had blood transfusion, and they were discharged from the hospital. Conclusions Without maternal and fetal blood group incompatibility (ABO or Rh blood-group system), for early onset of jaundice, severe jaundice or anemia, antiglobulin test to mother and child earlier should be administered, and MN, Kidd, Duffy and other rare hemolytic disease of the newborn should be pay attention to.

Objective: To explore the effect of heme oxygenase-1 (HO-1) on level of reactive oxygen species (ROS) induced by zinc oxide nanoparticles (ZnO-NPs) in Human umbilical vein endothelial cells line EA.hy926. Methods: The EA.hy926 cells in logarithmic growth phase were incubated with 0.0, 2.5, 5.0, 10.0 and 15.0 mg/L ZnO-NPs respectively. The ROS level, reflected by mean fluorescence intensity (MFI), was examined by flow cytometer after 4 hours exposure, the protein expression of HO-1 which was determined by Western Blot after exposed to ZnO-NPs for 24 hours. Cells incubated with 15.0 mg/L were set as the ZnO-NPs group; a blank control group was set at the same time. Cells were pretreated with HO-1 inhibitor zinc protoporphyrin (ZnPPIx) and HO-1 activator cobalt protoporphyrin (CoPPIx), they were classified as ZnPPIx group and CoPPIx group. 15 mg/L ZnO-NPs was chosen to conduct the experiment of HO-1 activation and inhibition. Cells were classified as ZnPPIX+ ZnO-NPs group and CoPPIx+ ZnO-NPs group after pretreated with 10 μmol/L ZnPPIx or CoPPIx for 1 h, added 15 mg/L ZnO-NPs to cell culture medium. In all groups ROS levels were detected after exposed to ZnO-NPs for 4 hours, the protein expression of HO-1 was detected after exposed to ZnO-NPs for 24 hours. Results: With the increased dose of ZnO-NPs, levels of ROS and HO-1 in EA.hy926 cells were clearly elevated (the MFI of 0.0, 2.5, 5.0, 10.0 and 15.0 mg/L ZnO-NPs incubated groups was 22 627.22±718.27, 24 726.47±568.52, 31 141.75±1 312.24, 39 824.82±4 774.74, 50 569.03±1 497.63 respectively, and HO-1 relative expression were 0.16±0.01, 0.19±0.02, 0.16±0.01, 0.23±0.02, 0.92±0.06 respectively). HO-1 expression in ZnPPIx pretreatment group decreased compared with ZnO-NPs group (1.05±0.05 vs. 1.12±0.01, P<0.05), meanwhile ROS level enhanced (62 683.95±2 589.59 vs. 53 654.53±2 229.01, P<0.05). However, CoPPIx pretreatment had higher HO-1 level and lower level of ROS compared with ZnO-NPs group (HO-1: 1.74±0.11 vs. 0.22±0.03, P<0.05; ROS: 32 845.04±993.48 vs. 53 654.53±2 229.01, P<0.05). Conclusions Exposure to ZnO-NPs significantly induced ROS generation in EA.hy926 cells in a dose-dependent manner. HO-1 regulated ZnO-NPs-induced oxidative stress.

Objective To explore the effect of Taijiquan on motor function and depression in patients with post-stroke depression. Meth-ods From January to October, 2015, 60 stroke patients with depression were randomly divided into control group (n=30) and Taijiquan group (n=30). Both groups accepted routine rehabilitation, while Taijiquan group accepted another training of six actions from simplified Taijiquan. They were assessed with Fugl-Meyer Assessment (FMA), Barthel Index (BI) and Hamilton Depression Rating Scale (HAMD) be-fore, and four and eight weeks after treatment. Results The scores of FMA and BI increased more in Taijiquan group than in the control group after treatment (t>2.351, P<0.05), while the score of HAMD decreased more (t>2.169, P<0.05). Conclusion Taijiquan can relieve the depression and improve the motor and activities of daily living in patients with post-stroke depression.

ObjectiveTo analyze the clinical manifestation of hemolytic disease of the newborn (HDN) due to anti-M and Rhesus system.MethodsClinical information was collected and analyzed for three cases with HDN due to anti-M and 64 with Rhesus hemolytic disease, who were admitted to Department of Neonatology, Beijing Children's Hospital Affiliated to Capital Medical University from February 2011 to January 2015, as well as another 28 cases of HDN due to anti-M with complete information retrieved from literature in Wanfang and China National Knowledge lnfrastructure (CNKI) Database from 1992 to 2014.Chi-square test was performed for statistical analysis.ResultsTwo out of the 64 Rh hemolytic babies gave up therapy due to kernicterus and another two out of the 31 MN hemolytic babies, obtained from literature, died 24 h after birth because of anemia or edema, while the rest survived. Although more babies were the first child of the family in HDN due to anti-M than those of Rh hemolytic disease [26%(8/31) vs 9%(6/64),χ2=4.487, P=0.034], but lower incidence of jaundice [81%(25/31) vs 98%(63/64),χ2=9.686,P=0.002], less proportion of presentation of jaundice within 24 h after birth [29% (9/31) vs 64%(41/64),χ2=10.279,P=0.001] and lower positive rate of direct antiglobulin test [39%(12/31) vs 100%(64/64), Fisher exact test,P=0.000] were shown in HDN due to anti-M. No significant difference was found in the incidences of hyperbilirubinemia [58%(18/31) vs 66%(42/64),χ2=0.513], severe hyperbilirubinemia [23%(7/31) vs 36%(23/64),χ2=1.724], anemia [81%(25/31) vs 89%(57/64),χ2=1.253] and severe anemia [29%(9/31) vs 34%(22/64),χ2=0.271] between HDN due to anti-M and Rh hemolytic babies (allP>0.05).ConclusionsHDN due to anti-M and Rhesus hemolytic disease can cause severe pathological jaundice and/or anemia in newborns. Indirect antiglobulin test should be offered when direct antiglobulin test is negative which is helpful in the diagnosis of HDN due to anti-M.

BACKGROUND:A large number of studies have shown that cast metal post-core has many advantages that it is close to the canal wal has high strength and can shape the core outside the root according to the needs. The cast metal post-core also has good retention, resistance and wel effect on clinical repair of dental defects. OBJECTIVE: To observe the clinical effect of Co-Cr aloy cast post-core and porcelain fused metal combined crowns in restoration of the separated mandibular molar residual crowns and roots. METHODS:Totaly 28 patients (42 teeth) who had the separated mandibular molar residual crowns and roots were enroled, including 10 males and 18 females, aged 18-32 years. After perfect root canal therapy and part of teeth with crown lengthening, teeth were repaired with Co-Cr aloy cast post-core and porcelain fused metal combined crowns. The patients were folowed up for 2 years. The repair effect was evaluated by combining clinical manifestations with X-ray examination. RESULTS AND CONCLUSION: During 2 years of folow-up, 26 cases were repaired successfuly, 2 cases failed, including 1 case of periapical periodontitis and 1 case of periodontitis. These results demonstrate that the cast post-core and porcelain-fused-metal combined crown has a good result on the residual root and crown of the separated mandibular molar.
