ABSTRACT
Objective:To preliminarily investigate the effect of circIGF2BP3 on autophagy in photoaged dermal fibroblasts.Methods:Human dermal fibroblasts were isolated from circumcised foreskin tissues from 6 children in the Department of Urological Surgery, Third Affiliated Hospital of Sun Yat-sen University. An ultraviolet A (UVA) -induced photoaged human dermal fibroblast model (UVA radiation group) was established by repeated UVA radiation at a dose of 10 J/cm 2 for 14 consecutive days, and human dermal fibroblasts receiving no treatment served as control group. The photoaged cell model was verified by β-galactosidase staining, Western blot analysis for determining P21 protein expression, and cell counting kit-8 (CCK8) assay for evaluating cell viability. Moreover, Western blot analysis was performed to determine the protein expression of autophagy-related proteins P62, microtubule-associated protein 1 light chain 3 (LC3) -Ⅰand LC3-Ⅱ in photoaged human dermal fibroblasts, and real-time quantitative RCR (qRT-PCR) to verify the differential expression of circIGF2BP3 between photoaged and normal human dermal fibroblasts. Furthermore, circIGF2BP3 was biologically annotated. Some cultured primary human dermal fibroblasts were divided into 4 groups: empty vector group transfected with an empty vector, UVA + empty vector group transfected with an empty vector followed by repeated UVA radiation, circIGF2BP3 group transfected with a circIGF2BP3-overexpressing lentiviral vector, UVA + circIGF2BP3 group transfected with a circIGF2BP3-overexpressing lentiviral vector followed by repeated UVA radiation. Western blot analysis was performed to determine the expression of autophagy-related proteins. Statistical analysis was carried out by using t test, one-way analysis of variance and least significant difference- t test. Results:Compared with the control group, the UVA radiation group showed significantly increased proportions of β-galactosidase-positive cells (61.33% ± 5.78% vs. 6.37% ± 0.32%, t = 9.49, P < 0.01) and P21 expression (1.25 ± 0.03 vs. 1.00 ± 0.05, t = 4.26, P < 0.05), but significantly decreased cell viability (74.33% ± 3.48% vs. 100%, t = 7.38, P < 0.01). Moreover, the P62 expression and LC3-Ⅱ/Ⅰ ratio were significantly higher in the UVA radiation group than in the control group (both P < 0.05). The relative expression of circIGF2BP3 was 0.72 ± 0.04 in the photoaged human dermal fibroblasts, which was significantly lower than that in the normal human dermal fibroblasts (1.00 ± 0.03, t = 5.46, P < 0.01). The P62 expression and LC3-Ⅱ/Ⅰ ratio were significantly lower in the circIGF2BP3 group (0.60 ± 0.01, 0.71 ± 0.01, respectively) than in the empty vector group (1.00 ± 0.02, 1.00 ± 0.01, t = 16.25, 2.75, P < 0.01, < 0.05, respectively), and lower in the UVA + circIGF2BP3 group (1.05 ± 0.02, 2.04 ± 0.05, respectively) than in the UVA + empty vector group (1.31 ± 0.02, 2.72 ± 0.14, t = 10.493, 6.472, respectively, both P < 0.01) . Conclusion:circIGF2BP3 can regulate autophagy in UVA-induced photoaged dermal fibroblasts, which provides a new potential therapeutic target for the prevention and treatment of skin photoaging.

ABSTRACT
Objective: To explore the changes of the graph theory metrics and the functional connectivity (FC) of adolescent depression with attempted suicide. Methods: Resting-state functional MRI (rs-fMRI) data of 33 patients of adolescent depression with attempted suicide (attempted suicide group), 40 patients of adolescent depression without attempted suicide (no suicide group) and 52 normal adolescents (NC group) were collected, and a binary network was constructed. The brain regions changed in the graph theory attribute were selected as the seeds, and FC between seed and all the other voxels within the whole brain was computed and compared among groups. Results: There were small world attributes in all subjects. Compared with NC group, the degree of centrality significantly decreased in adolescent depression patients (P<0.01), and there were negative correlations between the decreased degree of centrality and Hamilton Depression Scale scores (r=-0.31, P<0.01). Compared with NC group, FC of the somatomotor networks and the salience network decreased in adolescent depression patients, while FC of the attention network in attempted suicide group increased than in no suicide group (all TFCE correction, P<0.05). Conclusion: Decrease of visual network information transmission ability in patients of adolescent depression is related to the severity of depression. The abnormal attention space ability caused by the attention network lesions may be the pathological mechanism of suicidal attempt in patients of adolescent depression.
ABSTRACT
Objective@#To understand fruit and vegetable consumption of children and associated factors during COVID-2019 control period, and to provide basis for growth and development of children.@*Methods@#In February 2020, 334 parents of children aged 2 to 15 years old from 22 provinces, cities and autonomous regions, including Hubei, Beijing, Shandong, Gansu were surveyed through the "Questionnaire Star" network questionnaire for the students’ fruit and vegatable consumption during the period of COVID-19, and Logistic regression analysis was conducted with multivariate analysis.@*Results@#Among the children, 26.4% of their vegetable consumption and 45.2% of their fruit consumption had changed. The multivariate analysis showed that inconvenient purchase (OR=6.52) were related to the decrease of children’s vegetable consumption. The 2-5 age group(OR=0.28), whether parents actively gained relevant knowledge of diet (OR=0.33) and mild epidemic risk (OR=4.35) were related to the increase of children’s vegetable consumption(P<0.05). Average monthly income of family(OR=6.27-8.39), inconvenient purchase(OR=2.93), and epidemic risk (OR=0.21-0.26) were associated with reduced fruit consumption among children(P<0.05). While gender(OR=2.20), average monthly income of family below 2 000 yuan (OR=6.94) and mild epidemic risk (OR=0.35) were associated with increased fruit consumption among children(P<0.05).@*Conclusion@#Children’s fruit and vegetable consumption were greatly affected by the inconvenience of food purchase during the period of COVID-19. Low-income families were less resilient, and their children’s food consumption was more likely to be affected. Parents’ high level of nutritional knowledge could help weaken the adverse impact of the epidemic on children’s diet.

ABSTRACT
BACKGROUND@#The clinical features of patients with common single-mutation of epidermal growth factor receptor (EGFR) in non-small cell lung cancer (NSCLC) has been well characterized. There is a high adenocarcinoma incidence rate among female patients with none or shorter smoking history. Those patients have higher objective response rate (ORR) and progression free survival (PFS) treated with EGFR tyrosine kinase inhibitors (EGFR-TKIs). However, it is still unclear that the clinical features of patients with EGFR double mutation and the sensitivity towards EGFR-TKIs treatment.@*METHODS@#We performed a retrospective cohort study of 1,238 primary NSCLC patients who had EGFR gene testing in Affiliated Hospital of Qingdao University from January 1, 2015 to December 31, 2016 and identified 603 patients with single mutation and 59 patients with double mutation. All genes were uniformly detected by using ARMS-PCR technology. We analyze the gene of 32 double-mutant patients with specific genotyping, and randomly selected 60 patients with single mutation and compared the clinical features with 59 patients with double mutation. Furthermore, we examined the efficacy of EGFR-TKIs treatment in lung cancer patients with double mutation and single mutation in EGFR.@*RESULTS@#The rare single mutation gene is the most common in patients with double mutation of EGFR. There is no significant statistical difference in gender, smoking history, age, pathological type or tumor-node-metastasis (TNM) staging among patients with single and double EGFR mutantion. In the double mutation patients treated with EGFR-TKIs, the objective response rate was 36.80%, the disease control rate was 68.40%. The objective response rate was 60.00% and the disease control rate was 90.00% in the patients with single mutation. However, overall PFS was significantly higher in EGFR single mutation patients (P=0.003), with median PFS of 12.0 months compared with 6.0 months in EGFR double mutation patients.@*CONCLUSIONS@#There was no significant difference between the clinical features of patients with EGFR double mutation and single mutation. Patients with EGFR double mutation is associated with poor survival underwent the first generation of EGFR-TKIs treatment compared with patients with a single mutation.
