OBJECTIVE: To evaluate symptoms and quality of life in children with allergic rhinitis, and to evaluate the correlations among the skin prick tests results, symptoms and quality of life. METHOD: Visual analog scale (VAS) was used to assess the symptoms severity, rhinoconjunctivitis quality of life questionnaire (RQLQ) was used to assess quality of life, the skin prick tests results were recorded, and statistics analysis was carried out among them. RESULT: (1) There were significant differences among the five aspects of RQLQ (F = 32.03, P < 0.01), nasal symptoms aspect was the most affected aspect of quality of life, moreover, there were significant differences among all the items of RQLQ (F = 7.35, P < 0.01), the scores of nasal blockage, sneezing and rhinorrhea were the highest, there were no significant differences among them. (2) VAS was significantly correlated with RQLQ, moreover, the scores of unable to get to sleep and embarrassed by symptoms were significantly correlated with rhinorrhea VAS scores (r = 0.230, P < 0.05; r = 0.325, P < 0.01), the score of wake up during the night was significantly correlated with nasal itching and sneezing VAS scores (r = 0.385, P < 0.01; r = 0.231, P < 0.05), the score of can't concentrate was significantly correlated with the scores of unable to get to sleep and wake up during the night (r = 0.316, P < 0.01; r = 0.525, P < 0.01), the score of irritable was significantly correlated with the scores of unable to get to sleep (r = 0.243, P < 0.05). (3) The results of the skin prick tests were related with VAS and RQLQ. CONCLUSION Nasal symptoms severity may significantly correlated with the quality of life. Rhinorrhea, nasal itching and sneezing may be the main factors affecting the quality of sleep, while the quality of sleep may affect non-hay-fever symptoms and emotions, rhinorrhea may be the main factor affecting embarrassed by symptoms. The allergen level was related with the symptoms severity and quality of life.

Objective:To study the risk factors of extrauterine growth retardation (EUGR) during hospitalization in very preterm infants (VPIs) with birth weight (BW) <1 500 g.Methods:From Jan 2015 to Dec 2020, clinical data of VPIs admitted to neonatal department our hospital were retrospectively studied. The infants were assigned into EUGR group and non-EUGR group according to their weight at discharge. Multivariate logistic regression analysis was used to analyze the risk factors of EUGR in VPIs.Results:A total of 969 VPIs were enrolled, including 400 cases of EUGR (41.3%). Multivariate logistic regression analysis showed that Z-score of BW ( OR=0.057, 95% CI 0.037-0.088, P<0.001) was closely correlated with the occurrence of EUGR and growth velocity (GV) after regain BW ( OR=0.537, 95% CI 0.479-0.602, P<0.001) was a protective factor for EUGR. Maternal hypertension during pregnancy ( OR=1.895, 95% CI 1.059-3.394, P=0.031), asphyxia at birth ( OR=2.508, 95% CI 1.265-3.347, P=0.004) and moderate to severe bronchopulmonary dysplasia (BPD) ( OR=2.660, 95% CI 1.503-4.708, P=0.001) were risk factors for EUGR at discharge. Conclusions:EUGR is still common in VPIs. Increased GV after regain BW, prevention and treatment of moderate to severe BPD may reduce the incidence of EUGR at discharge in VPIs.

Dysfunction of the Hippo pathway enables cells to evade contact inhibition and provides advantages for cancerous overgrowth. However, for a significant portion of human cancer, how Hippo signaling is perturbed remains unknown. To answer this question, we performed a genome-wide screening for genes that affect the Hippo pathway in Drosophila and cross-referenced the hit genes with human cancer genome. In our screen, Prosap was identified as a novel regulator of the Hippo pathway that potently affects tissue growth. Interestingly, a mammalian homolog of Prosap, SHANK2, is the most frequently amplified gene on 11q13, a major tumor amplicon in human cancer. Gene amplification profile in this 11q13 amplicon clearly indicates selective pressure for SHANK2 amplification. More importantly, across the human cancer genome, SHANK2 is the most frequently amplified gene that is not located within the Myc amplicon. Further studies in multiple human cell lines confirmed that SHANK2 overexpression causes deregulation of Hippo signaling through competitive binding for a LATS1 activator, and as a potential oncogene, SHANK2 promotes cellular transformation and tumor formation in vivo. In cancer cell lines with deregulated Hippo pathway, depletion of SHANK2 restores Hippo signaling and ceases cellular proliferation. Taken together, these results suggest that SHANK2 is an evolutionarily conserved Hippo pathway regulator, commonly amplified in human cancer and potently promotes cancer. Our study for the first time illustrated oncogenic function of SHANK2, one of the most frequently amplified gene in human cancer. Furthermore, given that in normal adult tissues, SHANK2's expression is largely restricted to the nervous system, SHANK2 may represent an interesting target for anticancer therapy.
