RESUMEN
To analyze the clinical characteristics and treatment status of atopic dermatitis (AD) in children in the outpatient department of a children's hospital in Beijing from 2015 to 2019. This study used a cross-sectional study method to retrospectively analyze the data of AD patients who visited the Dermatology outpatient department of Beijing Children's Hospital, Capital Medical University, from April 2015 to April 2019. A total of 1 926 AD patients aged 0-17.5 years old living in Beijing and its surrounding areas were included, and the general situation, severity and distribution of AD disease, clinical characteristics and severity of AD, relevant influencing factors of AD onset, AD disease prognosis and treatment status were recorded. SAS 9.4, SPSS19.0, and R software were used for data processing, and descriptive statistical analysis, Chi-square test, Analysis of Variance, and correspondence analysis were used for statistical analysis. The results showed that the male to female ratio of AD patients in children included in this study was 1.4â¶1; 79.0% (1 522/1 926), 86.1%(1 658/1 926), 91.3%(1 758/1 926), and 97.3%(1 907/1 926) of AD onset at the age of 6 months, 1 year, 2 years, and 5 years, respectively; mild of AD patients accounted for 13.2% (255/1 926)(SCORAD score 0-24), moderate of AD patients accounted for 50.1%(965/1 926) (SCORAD score 25-50), and severe of AD patients accounted for 36.7% (706/1 926)(SCORAD score>50).The age of severe AD patients were younger than mild and moderate AD patients. The face, head, trunk, and lower limbs were common areas of onset for moderate to severe AD, while the hands, feet, and ears were common areas of onset for severe AD patients. Temperature changes, hot water factors, mental and emotional states, and spring and winter were the main aggravation factors of AD;35.2% (678/1 926) aggravated and 61.8% (1 191/1 926) persistent. The more frequent bathing, the less severity of AD disease (χ2=29.791,P<0.001); 28.0% (520/1 856) of AD patients have no moisturizing habits, which were correlated with the severity of AD disease (χ2=15.908, P<0.05); the proportion of combined treatment medications in children with moderate to severe AD was significantly higher than mild AD patients. In conclusion, the patients with AD who went to specialist clinics were mainly moderate to severe patients and developed disease before the age of 5 years from 2015 to 2019.The severity of AD were mainly moderate to severe, and most of these patients had poor disease control. Traditional treatment plans had limitations. Identifying the clinical characteristics and treatment status of childhood AD would help us to carry out more targeted prevention and management work.

Objective: To study the distribution and related factors of curative care expenditure (CCE) of injury in Gansu Province in 2017. Methods: Based on the "A System of Health Accounts 2011 (SHA 2011)", the curative care expenditure of injury in Gansu Province was calculated and analyzed. The five-stage stratified cluster sampling method was adopted to extract 149 medical and health institutions, 120 township hospitals (including community health service centers), 150 individual clinics and 600 village clinics (including community health service stations). The top-down allocation method was used to calculate the cost of injury treatment in Gansu Province, and the influencing factors were analyzed by multiple linear regression. Results: In 2017, the CCE of injury in Gansu province was 3.831 billion yuan, and the expense in general hospitals was 2.708 billion yuan. Among them, the cost of lower limb injury and head injury were 1.090 and 0.847 billion yuan. People aged 40 to 69 years old spent 1.901 billion yuan on injury treatment, and the CCE of injury treatment for men and women were 2.422 and 1.409 billion yuan respectively. The results of multiple linear regression showed that hospitalization expenditure was significantly associated with length of stay, operation, hospital grade, age, payment method and gender (P<0.001). Conclusion: The economic burden of injury in Gansu Province is relatively heavy, so it is necessary to focus on preventions for different groups and costly injury sites.

This study examined how an adult's descriptions of a situation could influence children's appraisal, feelings, and subsequent psychological functions. After baseline measures, 81 middle-class Singaporean kindergarten children (Mage = 5.6 years, SD = 0.6) were exposed to an ambiguous accident and provided with positive, negative, or no descriptions of the accident. Children's appraisal of the experience, feelings of pleasantness, motivation to play a new game, confidence in playing the new game well, and performance on the new game were measured. The results revealed that the descriptions of the accident influenced children's appraisal, feelings of pleasantness, motivation to play a new game, confidence in playing the new game well, and performance on the new game.

To improve the efficiency of somatic cell nuclear transfer (SCNT) in goats, we evaluated the effects of the interval between fusion and activation (1 to 5 h), cytochalasin B (CB) treatment after electrofusion, and the number of transferred embryos on the in vivo and in vitro development of cloned caprine embryos. The majority of the reconstructed embryos had condensed chromosomes and metaphase-like chromosomes at 2 and 3 h after fusion; cleavage and blastocyst rates from those two groups were higher (P < 0.05) than those of embryos activated 1, 4, or 5 h after fusion. Treatment with CB between fusion and activation improved in vitro and in vivo development of nuclear transfer (NT) goat embryos by reducing the fragmentation rate (P < 0.05). Although there were no significant differences in NT efficiency, pregnancy rate and kids born per recipient were increased by transfer of 20 or 30 embryos per recipient compared with 10 embryos. We concluded that CB treatment for 2 to 3 h between fusion and activation was an efficient method for generating cloned goats by somatic cell NT. In addition, increasing the number of embryos transferred to each recipient resulted in more live offspring from fewer recipients.

The combination of somatic cell nuclear transfer (SCNT) and transgenic technology leads to the production of transgenic cloned animals, wherein the preparation of competent transgenic donor cells is the pivotal upstream step. The purpose of this study was to establish an efficient procedure to prepare human lactoferrin (hLTF) transgenic donor cells for SCNT. Thus, two cell culture systems were employed: caprine mammary epithelial cells (for evaluation of the hTLF transgenic expression in vitro), and fetal-derived fibroblast cells (for identification of competent transgenic donor cells). Induced by hormonal signals, recombinant hLTF was detected in the supernatant of transfected mammary epithelial cells by Western blot. Reliable hLTF transgenic fibroblast cell clones were identified by screening with multiple PCR amplification, EGFP fluorescence, and chromosomal counting (32.5+/-2.3%). This study may provide an effective upstream system to prepare SCNT donor cells for the production of human recombinant pharmaceuticals from the milk of transgenic animals.

The objective was to investigate the effect of phytohemagglutinin (PHA) on the fusion of mammary gland epithelial (MGE) cells into enucleated oocytes in goats. The toxicity of PHA was evaluated by testing its effect on the development of parthenogenetic caprine oocytes. The effective dose and duration of PHA treatment (100 microg/mL, 20 min incubation) was selected and used to compare fusion efficiency and embryo development following nuclear transfer. Two electrofusion protocols, chamber fusion (CF) and pressurized microelectrode fusion (pMEF), were also compared, when couplets were treated with and without PHA (100 microg/mL, 20 min). Fusion rate of couplets increased from 52.8 to 74.0% for the CF protocol (P<0.05), but was not significantly different for the pMEF protocol (72.7% vs. 78.1%) after PHA treatment. There were no significant differences between treated group and control in rates of subsequent cleavage or blastocyst development. Following transfer of the cloned blastocysts derived from the PHA-treated group and the control group into synchronized recipients, pregnancy rates (Day 30) were not significantly different between treated group and control (28.6% vs. 25.0%). However, all recipients aborted within 120d, microsatellite DNA analyses confirmed that the aborted fetuses were genetically identical to the donor goat. In conclusion, the fusion rate of caprine MGE cell couplets was improved by pre-incubating couplets in medium containing 100 microg/mL PHA prior to electrical pulsing, and embryos derived from PHA treatment established early pregnancies.

Twenty-two centenarians and one hundred and seventy-nine nonagenarians (mean age 93 +/- 1.04 years) in the Shanghai Region of China were phenotyped for alleles of A (13 types), B (21 types) and C (6 types) loci of the human leukocyte antigen (HLA). The frequencies of HLA antigens were compared with 211 healthy adults whose ages ranged from 20 to 50 years. It was observed that A9 was highly associated with longevity (frequency in the longevity group is 38%, the control group 24%, P = 0.002). A30 showed marked inverse correlation (frequency in the longevity group is 8%, the control group 17%, P = 0.008). Cw3, Cw6 and Cw7 were also inversely correlated (P = 0.02, 0.04 and 0.02, respectively). Thus, it is likely that A9 may contribute to longevity while A30, Cw3, Cw6 and Cw7 may be associated with aging. The average superoxide dismutase (SOD) contents of erythrocytes in 48 cases with the HLA-A9 (without A30) antigen in the longevity group and in 13 cases with the HLA-A30 (without A9) antigen in the control group were 555 +/- 96 and 593 +/- 58 micrograms/gHb, respectively (t = 1.375, P > 0.05).

An analysis of 105 cases of prematures with respiratory distress syndrome, the idiopathic type were 9.5% (10/105). Fetal anoxia and ischemia, induced by pregnancy and during labour amounting to 87.6% (92/105), and of which 2.9% (3/105) was due to diabetes. It indicated that most cases of RDS are predominantly related with fetal anoxia and ischemia which results in pulmonary surfactant abnormality or impaired activity. It is important that in clinical diagnosis one should monitor cautiously the presence of premature birth with anoxia and ischemia, Thus, a preventive treatment must be given at least 24 hours prior to birth, and the earlier the least morbidity of RDS occurred.
