DiGeorge(DGS)syndrome is an autosomal dominant disorder caused by 22q11.2 microdeletions,most patients developed the disease in childhood.22q11.2 deletion syndrome,and the mutation types are dominated by haploid deletion of this gene.We report a young patient with hypoparathyroidism(parathyroidism)induced by DGS syndrome combined with hypocalcemic heart failure.Genetic testing revealed pathogenic copy number variants associated with the clinical phenotype of the subject.About 2 674 kb of deletion variation was detected at q11.21 position on chromosome 22,which contained the TBX1 gene and was a pathogenic mutation.This paper discusses the clinical features,pathogenesis and current treatment of DGS,and emphasizes the importance of early screening,early diagnosis and treatment,and regular follow-up of heart failure,aiming to enhance the awareness of clinicians and geneticists on DGS syndrome.

Objective:To explore the application effect of nurse-led navigation service in the economic toxicity management of prostate cancer patients, and to provide reference for the economic toxicity management of prostate cancer patients.Methods:By using the method of historical control study, 60 patients with prostate cancer admitted to Beijing Friendship Hospital, Capital Medical University were selected as the research subjects by convenience sampling from March to August 2023. According to the time sequence of admission, 30 patients admitted from March to May 2023 were included in the control group, and 30 patients admitted from June to August 2023 were included in the intervention group. The control group was given routine nursing, and the intervention group was given nurse-led navigation service. The patients were evaluated at admission, discharge and 3 months after discharge using the Comprehensive Scores for Financial Toxicity Based on the Patient-Reported Outcome Measures and the Compliance Behavior Questionnaire.Results:The age of the control group patients was ( 70.07 ± 5.76 ) years, and the age of the intervention group was ( 68.80 ± 7.22 ) years. The economic toxicity scores of the intervention group at discharge and 3 months after discharge were ( 35.13 ± 4.84 ) and ( 37.90 ± 4.89 ), respectively, which were higher than those of the control group ( 21.70 ± 2.52 ) and ( 21.33 ± 2.94 ), the differences were statistically significant ( t=-13.48, -15.89, both P<0.05 ). The complete compliance rate of the control group was 46.67 % (14/30), which was lower than 73.33% (22/30) of the intervention group, and the difference between the two groups was statistically significant ( χ2=4.44, P<0.05). Conclusions:Nurse-led navigation services can effectively monitor and evaluate the level of economic toxicity in patients with prostate cancer, reduce the degree of economic toxicity in patients with prostate cancer, help improve patients′ compliance behavior, and help patients cope with economic toxicity in a positive way.

Bombyx mori is a lepidopteran insect with important economic value. Bombyx mori nucleopolyhedrovirus (BmNPV) causes huge economic loss to silkworm industry in China every year. The objective of this study is to determine the anti-BmNPV mechanism of Bombyx mori strain NC99R, and to provide a basis for understanding the molecular mechanism of the silkworm resistance strain. The normal control Dazao (DZ) strain and the NC99R resistant strain were fed with occlusion bodies (OB). The median lethal dose (LD50) analysis of the DZ and NC99R showed that the LD50 of DZ was 1.2×10⁵ OBs/larva, while NC99R was 1.8×10⁶ OBs/larva. The LD50 of the NC99R was about 15 times higher than the DZ. The mortality of DZ and NC99R were analyzed, which were fed with 1×10⁶ OBs/larva and injection with 1×10⁶ BVs/larva. The results showed that the death peak of DZ was concentrated in the 4th to 6th day. And the death peak of NC99R was concentrated in the 6th to 8th day, with a delay of 1-2 days compared with the control. The BmNPV DNA copy number showed that the BmNPV genome in DZ proliferated rapidly. The copy number of BmNPV DNA in NC99R were increased slowly after oral infection and body injection. HE staining showed that midgut tissue has no significant difference between DZ and NC99R in the early stage of oral infection. At 96 h p.i., the nucleus of DZ midgut became larger and shedding. The NC99R had enlarged nuclei, but the cells were still arranged neatly. Finally, the expression of virus genes in different periods were analyzed by RT-PCR. The results indicated that the immediate early gene ie-1 expression levels began to down-regulate after 24 h p.i.. The early, late, and extremely late genes were also down-regulated, and finally maintained at a lower expression level.
