Objective:
To investigate the dynamic expression of placenta growth factor (PlGF) in the lungs and its role in paraquat-induced pulmonary fibrosis and to evaluate the effect of ACEI captopril and AT (1) -receptor blocker losartan on paraquat-induced pulmonary fibrosis.
Methods:
84 adult healthy female Sprague-Dawley (SD) rats were randomly divided into four groups of different treatments designated as: Control, PQ alone (PQ) , captopril treatment, losartan treatment. Each group was divided into three subgroups of seven animals each. The animals were killed at either 7, 14 or 28 days after PQ administration. The rats in PQ group, treatment group were treated intragastrically (ig) with PQ (40 mg/kg) and the rats in control group were treated with the same dose of saline at the beginning of the experiment. The treatment group received Captopril (60 mg/kg; ig) or Losartan (10 mg/kg; ig) once a day respectively after PQ administration and the other two groups received saline. At the given timepoint, animals were sacrificed and lungs were harvested. A semiquantitative assay of histological examination, hydroxyproline in lung tissues were used to determine the severity of alveolitis and fibrosis. RT-PCR and immunohistochemistry were used to detect the mRNA and protein expression of PlGF.
Results:
Inflammatory cell infiltration and fibrotic scores were more prominent in the model group, hydroxyproline contents in lung tissue were significantly increased after PQ administration compared to the control group. Captopril, losartan apparently attenuated the degree of lung injury and pulmonary fibrosis. On 7th, 14th days, the levels of alveolitis in the intervention groups were significantly alleviated as compared with the model group (

Objective To detect chromosomal aberrations of autism spectrum disorder (ASD), we performed karyo?types analyses in 632 ASD trios and then investigated whether copy number variants and neurodevelopment related genes are present in the regions of chromosomal aberrations. Methods Karyotypes analyses were performed in 632 ASD trios (1896 individuals). In addition, we investigated whether there were pathogenic copy number variants located in the rele?vant regions of detected aberrant karyotypes by using the database of the International Standards for Cytogenomic Arrays (ISCA) and the Genomic Variation and Phenotype in Humans using Ensembl Resources (DECIPHER) for ASD patients. Results We detected aberrant results in 22 of 632 patients (3.48%) by karyotypes analyses. Of these 22 aberrant karyo?types, 5 were de novo (0.79%), including the duplication, the translocation, karyotypes of Turner syndrome and the addi?tional material with unknown origin. Seventeen children affected with autism had aberrant karyotypes inherited from one of their parents. By using the ISCA and the DECIPHER database, we found that several copy number variants with high pathogenicity were located in 1q25 and 3p24. Further, these copy number variants consisted of several genes related to neurodevelopment such as TNR, ASTN1, and NMNAT2. Conclusion There are a few de novo chromosomal aberrations in some patients affected with ASD. Copy number variants of several pathogenic neurodevelopmental related genes may exist in the regions of chromosomal aberrations. Karyotypes analyses may be applied to explore the genetic etiology in some patients affected with ASD.

Objective:
To summarize the clinical features of leukoencephalopathy with vanishing white matter disease (VWM) in children.
Methods:
A retrospective cohort study was performed on 54 genetically diagnosed VWM patients in Peking University First Hospital from January 2007 to March 2019. Paper registration form and electronic medical record system were used to collect the data,and the children were divided into five groups according to the age of disease onset:<1 year, 1-<2 years, 2-<4 years, 4-<8 years and 8-<18 years respectively. The progression of motor function, episodic aggravation, epileptic seizures, survival time, brain magnetic resonance imaging (MRI) and genotype features were analyzed and compared. Non-parametric test, χ2 test or Fisher′s exact test were used for comparison among groups; Kaplan-Meier survival curve was adopted to delineate the survival status of the children.
Results:
Fifty-four VWM patients were included in the study, including 34 males and 20 females.The age of disease onset was 2 years and 8 months (ranged from 6 months to 9 years and 7 months). Onset age was less than 1 year in 5 cases; onset age was 1-<2 years in 12 cases; onset age was 2-<4 years in 25 cases; onset age was 4-<8 years, in 10 cases; onset age was 8-<18 years in 2 cases; 94% (51/54) of patients had complaint of motor regression at the first visit; 87% (47/54) of patients suffered from episodic aggravation. Episodic seizures occurred in 43% (23/54) patients. In survivors with disease durations of 1-3 years, in 38% (9/24) patients the disease was classified as grades Ⅳ-Ⅴ by gross motor function classification system (GMFCS). For the onset age 1-<2 years group, 1 patient was classified as GMFCS Ⅳ among 3 survivors with disease durations of 1-3 years. As for the 2-<4 years group, 6 patients were classified as GMFCS Ⅳ-Ⅴ among 15 patients with disease durations of 1-3 years, whereas 1 patient was classified as GMFCS Ⅳ-Ⅴ among 4 patients with disease durations of 1-3 years in the 4-<8 years group. Lesions, liquefaction and diffusion restriction in brain MRI were compared among different groups, and it was revealed that the earlier the age of disease onset was, the more likely the subcortical white matter (frontal lobe
