The baculoviral inhibitors of apoptosis play a significant role in infectivity and viral host-range, which make them potential candidates for the engineering and improvement of baculovirus insecticidal. The iap3 gene of Spodoptera exigua nucleopolyhedrovirus (SeMNPV), amplified by PCR, was 939 bp encoding IAP3. The PCR product was cloned into EcoR I/Bam H I of the plasmid pEGFP-C1. GFP was fused to the N-terminaus of IAP3 to study distribution in HEK293. It was observed that the plasmid expressing IAP3 significantly inhibited apoptosis induced by cisplatin in HEK293 cells. We conclude that the IAP3 of SeMNPV is functional in mammalian cells.

OBJECTIVE: To investigate the relationship between 22q11.2 duplication and clinical phenotype. METHODS: Eight fetuses with 22q11.2 duplication syndrome diagnosed by chromosome microarray analysis (CMA) through amniocentesis from February 2015 to March 2017 were enrolled in the study. The prenatal diagnostic indications, fetal ultrasound, chromosome karyotype, peripheral blood CMA results of parents, pregnancy outcomes and follow-up of postnatal growth and development were retrospectively analyzed. RESULTS: Prenatal serological screening indicated 6 cases with high risk of trisomy 21, 1 case with nuchal fold (NF) thickening and 1 case of maternal chromosomal balanced translocation. Fetal ultrasonography showed 1 case of NF thickening, 1 case of fetal cerebral ventriculomegaly and 6 cases with normal ultrasound. CMA demonstrated that the size of duplication was between 651 kb and 3.26 Mb, and 22q11.2 duplication. Parents' CMA results revealed that 6 cases inherited from one of the parents with normal phenotype, and the parents of 2 cases refused the CMA test. Two couples chose induced labor; 6 cases of continued pregnancy had normal phenotypes at birth. All 6 cases were followed up with longest of 3.5 years. The growth and psychological development were normal in 5 cases, and one case was growth retardation. CONCLUSIONS There were no specific clinical phenotypes in 22q11.2 duplication syndrome, and most of them were inherited from one parent who has normal phenotype.

Objective: To investigate direct and indirect economic burden, psychological impact, and quality of life in patients with psoriasis. Methods: Patients with psoriasis were recruited nationwide from "the psoriasis patient mutual assistance network" , a WeChat official account of "psoriasis patient mutual assistance platform" , and WeChat groups of psoriasis patients in different regions between July and September in 2018. An internet-based online questionnaire survey was carried out on these patients by using a self-designed questionnaire and Dermatology Life Quality Index (DLQI) scale. Comparison of enumeration data was carried out by using chi-square test, and comparison of measurement data by using Mann-Whitney U test. Results: A total of 497 valid questionnaires were collected, and 497 patients with psoriasis were enrolled into this survey, including 190 patients with mild to moderate psoriasis and 307 patients with severe psoriasis. These patients were from 8 geographic regions of China, and mainly in east China and north China. The total annual expenditure for psoriasis per patient accounted for 20% (8%, 50%) (M[P25, P75]) of the total annual income, the annual hospitalization rate was 21.3%, the annual sick leave or absence duration was 15.0 (1.0, 40.0) days, and the unemployment rate due to psoriasis was 37.0%. Of the 497 patients, 443 (89.1%) suffered from mental stress due to psoriasis, 169 (34.0%) had suicide intention, and 23 (4.6%) had ever attempted suicide. The DLQI score for all the patients was 14 (8, 19) , 307 (61.8%) patients reported a severe or extremely severe impact on the quality of life (DLQI > 10, severe psoriasis group) , and 190 (38.2%) patients reported a mild or moderate impact on the quality of life (0 ≤ DLQI ≤ 10, mild to moderate psoriasis group) . Compared with the mild to moderate psoriasis group, the severe psoriasis group showed a significantly higher ratio of total annual expenditure to total annual income (30% vs. 10.0%, P < 0.01) , hospitalization rate (26.4% vs. 13.2%, P < 0.01) , annual sick leave or absence duration (20.0 days vs. 5.5 days, P < 0.01) , unemployment rate (47.9% vs. 19.5%, P < 0.01) , proportion of patients with mental stress (99.0% vs. 73.2%, P < 0.01) , proportion of patients with suicide intention (46.3% vs. 14.2%, P < 0.01) and proportion of patients who had suicide behavior (6.8% vs. 1.1%, P < 0.01) . Conclusions Psoriasis imposes heavy economic and psychological burden on patients, and decreases their quality of life. Meanwhile, patients with severely or extremely severely affected quality of life have higher disease burden compared with those with mildly to moderately affected quality of life.
