Objective:
To explore trends in the asthma burden among Chinese children and adolescents 1-19 years old during 1990-2019.
Methods:
Based on data from the 2019 Global Burden of Disease Study, joinpoint regression was used to analyze the dynamic changes in the gender and age specific asthma burden, and the asthma burden in China was compared with countries that have different socio demographic indices(SDI). In addition, trends in asthma burden attributed to different risk factors were also investigated.
Results:
The asthma burden decreased slightly from 1990 to 1996 [annual percent change (APC)=-1.7%], then rapidly decreased from 1996 to 2005 (APC=-5.7%). The age standardized disability adjusted life years (DALYs) rate decreased from 158.55/100 000 to 88.59/100 000 in patients 1-19 years of age. From 2005 to 2017, the DALYs rate for asthma increased slowly, then rapidly. In 2017, the DALYs rate peaked at 176.18/100 000, then decreased to 126.79/100 000 in 2019. The burden of asthma in boys was higher than girls, and the DALYs rate for asthma in the group 5-9 years of age was higher than the remaining age groups. Furthermore, the age standardized DALYs rate for asthma among Chinese children and adolescents was relatively low among countries with a different SDI. In addition, the DALYs rate attributed to high body mass index increased in all age groups in China. Specifically, the average APC (AAPC) was 2.9% in group 1-4 years of age and the AAPC was 4.2% in the remaining age groups. The DALYs rate attributed to occupational asthmagens in the group 15-19 years of age decreased from 1990 to 2019 and the AAPC was -2.5%.
Conclusion
The asthma burden was relatively low among Chinese children and adolescents, and there were gender and age differences. The gender and age specific DALYs rate for asthma had a tendency to decrease, increase, then decrease. More attention should be paid to boys and the group 5-9 years of age, and strengthen the intervention of obesity and occupational asthmagens.

OBJECTIVE: To systematically evaluate the efficacy and safety of hydrotalcite combined with omeprazole for gastric ulcer, and to provide evidence-based reference for clinical treatment. METHODS: Retrieved from PubMed, Embase, Medline, the Cochrane library, CNKI, VIP and Wanfang database, randomized controlled trials (RCTs) about hydrotalcite combined with omeprazole (trial group) versus omeprazole alone (control group) for gastric ulcer during the database establishment to Aug. 2018. After data extraction of included literatures met inclusion criteria, and quality evaluation with Cochrane evaluator manual 5.0.1, Meta-analysis was performed for response rate, the incidence of ADR, recurrence rate of gastric ulcer bleeding, needed time of clinical symptom improvement and hospitalization stays by using Rev Man 5.3 statistical software. RESULTS: A total of 16 RCTs, involving 1 802 patients were included. The results of Meta-analysis showed that response rate [RR=1.24, 95%CI(1.19,1.29), P<0.001] of trial group was significantly higher than that of control group; recurrence rate of gastric ulcer [RR=0.27,95%CI(0.17,0.45),P<0.001], clinical symptom improvement time [MD=-2.04,95%CI(-2.25, -1.83),P<0.001] and hospitalization time [MD=-4.25,95%CI(-4.55,-3.95),P<0.001] of trial group were significantly lower or shorter than those of control group, with statistical significance. There was no statistical significance in the incidence of ADR [RR=0.68,95%CI(0.46,1.02),P=0.06] between 2 groups. CONCLUSIONS: Compared with omeprazole alone, hydrotalcite combined with omeprazole for gastric ulcer can obviously increase the clinical response rate, decrease the recurrence rate of gastric ulcer and shorten the needed time of clinical symptom improvement and hospitalization time, but do not increase the incidence of ADR.

Tooth decay is prevalent, and secondary caries causes restoration failures, both of which are related to demineralization. There is an urgent need to develop new therapeutic materials with remineralization functions. This article represents the first review on the cutting edge research of poly(amido amine) (PAMAM) in combination with nanoparticles of amorphous calcium phosphate (NACP). PAMAM was excellent nucleation template, and could absorb calcium (Ca) and phosphate (P) ions via its functional groups to activate remineralization. NACP composite and adhesive showed acid-neutralization and Ca and P ion release capabilities. PAMAM+NACP together showed synergistic effects and produced triple benefits: excellent nucleation templates, superior acid-neutralization, and ions release. Therefore, the PAMAM+NACP strategy possessed much greater remineralization capacity than using PAMAM or NACP alone. PAMAM+NACP achieved dentin remineralization even in an acidic solution without any initial Ca and P ions. Besides, the long-term remineralization capability of PAMAM+NACP was established. After prolonged fluid challenge, the immersed PAMAM with the recharged NACP still induced effective dentin mineral regeneration. Furthermore, the hardness of pre-demineralized dentin was increased back to that of healthy dentin, indicating a complete remineralization. Therefore, the novel PAMAM+NACP approach is promising to provide long-term therapeutic effects including tooth remineralization, hardness increase, and caries-inhibition capabilities.
