RESUMEN

Objective: To investigate the effect of China Children's Asthma Action Plan (CCAAP) on the exercise status of school-age children with asthma. Methods: We included 400 school-age asthmatic children as research objects from CCAAP asthma management platform of the Affiliated Hospital of Qingdao University during March 1, 2018 to February 28, 2021 by simple random sampling method. The questionnaires of basic information and international physical activity were applied through WeChat or face to face investigation to collect the basic information and exercise status of the object. There were 346 valid questionnaires included in the study to compare the differences in exercise status and incidence of exercise-related asthma-like symptoms between the good and poor CCAAP application groups. Results: There were 232 (67.05%) and 114 (32.95%) cases in good and poor CCAAP application group, respectively. Age, female proportion and BMI of good CCAAP application group were (8±2) years, 47.0% (109/232) and (19.79±2.32) kg/m2, respectively, no statistic difference comparing to poor CCAAP application group [(8±2) years, 46.5% (53/114) and (19.87±2.43) kg/m2, respectively] (all P values>0.05). In good CCAAP application group, 30.18% (70/232) achieved the standard of moderate (high) intensity exercise per day, no statistic difference comparing to poor CCAAP application group [29.82% (34/112)] (P=0.947); 31.90% (74/232) participated in high-intensity exercise per week, higher than that of poor CCAAP application group [17.54% (20/112)] (P=0.005); incidence of exercise-related asthma-like symptoms was 19.83% (46/232), lower than that of poor CCAAP application group [29.82% (34/112)] (P=0.038). Conclusion: CCAAP promotes the exercise of school-age children with asthma.

RESUMEN

A full-length cDNA encoding a general odorant binding protein 2 (GOBP2) was cloned from the antennae of the rice striped stem borer, Chilo suppressalis (Lepidoptera: Pyralidae), by the combination of reverse transcription PCR (RT-PCR) and rapid amplification of cDNA ends PCR (RACE-PCR). The cDNA contains a 489 bp open reading frame, which encodes a 162 amino acid protein, termed as Ch. suppressalis GOBP2 (CsupGOBP2). CsupGOBP2 is similar in the number of amino acids and protein sequence to GOBP2s in other species of Lepidoptera. RT-PCR results showed that CsupGOBP2 mRNA was highly expressed in the adult antennae of both females and males, as was CsupGOBP2 protein as revealed by Western blot analysis. CsupGOBP2 expressed in Escherichia coli was purified by affinity chromatography, refolding and gel filtration from the inclusion body. Fluorescence emission spectra and competitive binding assays by using N-phenyl-1-naphthylamine as first binding ligand and odorants as potential competitors revealed that the CsupGOBP2 protein has significant affinity to cis-11-hexadecenal (Z11-16:Ald), the main component of Ch. suppressalis pheromone and to laurinaldehyd and benzaldehyde, two general plant volatile aldehydes.

RESUMEN

Objective:The aim of this study is to investigate the inhibition of nasopharyngeal carcinoma cells by indole-3-carbinol in vitro and in vivo.Method:The human nasopharyngeal carcinoma cell line CNE2 was treated in different concentrations 0,100,200,300 µmol/L of indole-3-carbinol. Then we detected cell proliferation after 0,24,48 and 72 h, apoptosis after 48 h and the levels of PI3K/Akt pathway-related proteins in vitro. The BALB/c nude mice were divided into three groups: prevention group, treatment group and control group. In vivo, the nude mice in every group were inoculated with nasopharyngeal carcinoma cells CNE2, and mice in prevention and treatment groups were given feed containing 0.5% indole-3-carbinol. We investigated the tumoricidal effect of I3C in nude mice , and eight weeks later, the PI3K/Akt pathway-related proteins expressions in tumors from nude mice of each group were detected.Result:With the indole-3-carbinol concentration increased, cell proliferation decreased and apoptosis increased significantly.The levels of PI3K/Akt pathway-related proteins were decreased.In animal experiments, the prevention and treatment group developed smaller tumors, and the expression of PI3K/Akt pathway-related proteins in prevention and treatment groups PI3K/Akt pathway also reduced, compared to control group. Meanwhile, nearly no changes of heart, liver and kidney tissues in all groups were seen in HE staining.Conclusion:Indole-3-carbinol inhibited the growth of nasopharyngeal carcinoma cells and induced apoptosis effectively in vivo and in vitro. The mechanism might be that indole-3-carbinol could suppress PI3K/Akt pathway.
