Objective To study the effects of dust mite immunotherapy on the hormonal dosage, specific immunoglobulins G4(sIgG4)level and pulmonary function in asthmatic children.Methods One hundred and twenty-four cases of asthmatic children were randomly divided into specific immunotherapy treatment(SIT) group (62 cases, treated with the dust mite immunotherapy) and inhaled corticosteroids (ICS) group (62 cases, treated with ICS). The changes of clinical symptoms, serum sIgG4 level, pulmonary function and ICS dosage before and after treatment were compared between two groups. Results After treatment for 12,18,and 24 months, the scores of childhood asthma control test(C-ACT) in SIT group were significantly higher than those in ICS group:(23.84 ± 1.15)scores vs.(22.75 ± 1.08) scores, (24.29 ± 1.27)scores vs.(23.17 ± 1.22)scores, (24.83 ± 1.40)scores vs.(23.88 ± 1.34)scores, there were significant differences (P<0.05). After treatment for 12, 24 months, the level of serum sIgG4 in SIT group were significantly higher than those in ICS group:(308.75 ± 102.96) μg/L vs. (239.64 ± 79.35) μg/L, (542.28 ± 113.37) μg/L vs. (243.65 ± 80.21) μg/L, there were significant differences (P<0.05). After treatment for 12, 24 months, the levels of percentage of forced expiratory volume in 1 second (FEV1%), percentage of maximal expiratory flow rate (PEF%) in SIT group were significantly higher than those in ICS group: FEV1%:(95.82 ± 7.64)% vs. (92.79 ± 8.52)%, (99.52 ± 8.17)% vs.(95.89 ± 7.53)%;PEF%:(95.78 ± 5.85)% vs.(93.54 ± 6.18)%,(99.77 ± 5.69)% vs. (97.61 ± 5.56)%, there were significant differences (P<0.05). After treatment for 12, 24 months, the scores of daytime asthma symptoms scale (DAS) and nocturnal asthma symptoms scale (NAS) in SIT group were significantly lower than those in ICS group:DAS:(1.75 ± 0.54)scores vs.(1.96 ± 0.60)scores, (0.84 ± 0.27) scores vs. (1.19 ± 0.38) scores;NAS: (0.75 ± 0.27) scores vs.(0.92 ± 0.30) scores, (0.55 ± 0.18)scores vs.(0.81 ± 0.24)scores, there were significant differences(P<0.05).After treatment for 12, 24 months, the dosage in SIT group was significantly lower than those in ICS group:(172.08±16.73)μg/d vs.(194.63 ± 14.17)μg/d,(138.09 ± 16.23)μg/d vs.(163.15 ± 15.38)μg/d, there were significant differences(P<0.05).Conclusions Dust mite immunotherapy can effectively improve the clinical symptoms and pulmonary function in children with dust mite allergy asthma and reduce the ICS dosage, it may be related to the increase of protective antibody sIgG4 in children.

A 13-year-old male patient presented with skin abnormalities for more than 10 years and slow growth in body height for more than 5 years. Since the age of 6 months, erythema and scales had occurred on the extremities, and gradually spread to the trunk and face; brown pigmentation and punctate depigmentation appeared after subsidance of the erythema and scales, accompanied by dental caries, thickened palms and soles, nail thickening and peeling. Since the age of 6 years, the patient had presented with slow growth in body height, gonadal dysgenesis, sparse eyebrows and eyelashes, flat cheekbones and lameness in walking. In the past 10 years, neutrophil count had been found to be continuously lower than the normal reference value. Blood routine examination showed a neutrophil count of 1.1 × 10 9/L and a neutrophil proportion of 0.345; serum level of testosterone in the patient (< 0.087 nmol/L) was lower than normal levels. DNA was extracted from the peripheral blood of the patient and his parents, and gene mutation analysis was carried out by using whole-exome sequencing technology. Genetic testing showed compound heterozygous mutations in the USB1 gene of the patient, including the c.450-2A>G mutation inherited from his mother and the c.335de1G mutation inherited from his father, and the c.335de1G mutation had not been reported in China and other countries.

Objective: There were associations between emotional abuse and neglect (EAN) and depression, but few studies had tested potential mechanisms underlying these relationships. We aimed to provide insights on how (the mediation role of neuroticism), and under what conditions (the moderator role of psychological resilience), led to a higher level of depression. Methods: This study was a cross-sectional study that used a random cluster sampling method. We randomly selected 3,993 participants from four junior middle schools in northern city of China. Participants were asked to complete four self-reported questionnaires, including the Childhood Trauma Questionnaire, Children Depression Inventory-Short Form, Chinese Big Five Personality Inventory Brief Version, and Chinese Resilience Scale. Results: The results showed that neuroticism mediated the associations between EAN and depression. In addition, the mediating effect of neuroticism was moderated by psychological resilience (p<0.05). Conclusion EAN and neuroticism could have an adverse impact on depression, and psychological resilience could alleviate these negative effects as a moderator. Our model suggested psychological resilience could be a particularly effective intervention point for victims of EAN.

Objective To explore the effects of Qa-1 and PD-L1 loaded artificial liposomal treatment in allograft rejection and its outcomes .Methods The extracellular domains of Qa-1 and PD-L1 were loaded on liposome surface by streptavidin-biotin system . Mixed lymphocyte reaction (MLR) was performed for measuring Qa-1/PD-L1 liposome biological function .Then liposome was co-transplanted with allo-islets via portal vein .The levels of blood glucose and C-peptide were detected daily after transplantation .Also hepatic lymphocytes after transplantation were isolated for determining the proportion of activated cells and signaling pathway changes .Results Artificial liposome could be easily loaded with biotinylated peptide and its diameter was between 50 to 500 nm . Qa-1/PD-L1 liposome could significantly suppress lymphocyte proliferation , activation and secretion of IFN-γ in MLR by an activation of SHP1/2 and an inhibition of Syk pathway .Qa-1/ PD-L1 liposomes could suppress the activation of hepatic lymphocytes in vivo by activating SHP1/2 ,protecting islet allografts and maintaining a normal level of blood glucose in recipients .Conclusions Qa-1/PD-L1 loaded liposome can effectively suppress allograft rejection and improve the outcomes of islet transplantation .
