Objective: To explore current vitamin D status and influential factors of vitamin D deficiency and insufficiency among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China. Methods: According to the "province-city-hospital" sampling technical route, a total of 1 531 healthy children under 7 years of age were sampled from 11 provinces, autonomous regions or municipalities in China by the cluster random sampling method from November 2020 to November 2021. The demographic information, family conditions, behavior and living habits and feeding behaviors were collected using unified questionnaire. Serum 25-hydroxyvitamin D(25(OH)D) levels were measured by liquid chromatography-tandem mass spectrometry. Serum 25(OH)D<30 nmol/L was considered deficient and 30-50 nmol/L was considered insufficient. With 25(OH)D≤50 nmol/L as the dependent variable, multivariate Logistic regression was applied to analyze the association between vitamin D deficiency and insufficiency and potential influential factors. Results: The prevalence of vitamin D deficiency and insufficiency among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China was 14.0% (215/1 531), 3.8% (25/664) and 21.9% (190/867) in 0-<3 and 3-<7 of age years, respectively. Compared to children aged 0-<3 years, children aged 3-<7 years had a 2.6-fold increased risk of vitamin D deficiency and insufficiency (OR=3.60, 95%CI 1.93-6.72, P<0.001). Frequent sunlight exposure (OR=0.46, 95%CI 0.29-0.73, P=0.001), vitamin D supplementation (sometimes, OR=0.33, 95%CI 0.21-0.51, P<0.001; daily, OR=0.20, 95%CI 0.11-0.36, P<0.001) and infant formula intake(4-7 times per weeks, OR=0.43, 95%CI 0.28-0.68, P<0.001) were protective factors for vitamin D deficiency and insufficiency. Conclusion: Vitamin D deficiency and insufficiency are common among children under 7 years of age in 11 provinces, autonomous regions or municipalities of China, which is affected by age, sunlight exposure, vitamin D supplementation and infant formula intake.

OBJECTIVE@#To observe the therapeutic effect of herb-separated moxibustion combined with budesonide nasal spray (rhinocort) on moderate to severe persistent allergic rhinitis (AR) of kidney- deficiency type, and to explore the correlation between nasal temperature and condition of allergic rhinitis.@*METHODS@#A total of 70 patients with moderate to severe persistent AR were randomized into an observation group (35 cases) and a control group (35 cases, 3 cases dropped off). Both groups were treated with rhinocort, one spray on each side of the nostril (approximately 64 μg each spray), once in the morning and once in the evening, for 4 weeks. On the basis of the above treatment, the observation group was treated with herb-separated moxibustion at Shenshu (BL 23), Feishu (BL 13), Zhiyang (GV 9), Dazhui (GV 14), 3 moxibustions per acupoint, a single treatment lasting about 30 min. This treatment was given once every other day, 3 times every week, and totally continuous 4 weeks. The changes of AR symptom visual analogue scale (VAS) scores were observed before and after treatment and at 3 months follow-up after treatment. The heat variation (temperature, range) on projection areas of the nose, lungs, large intestine and kidneys of the two groups' patients before and after treatment were detected by the infrared thermal imaging diagnostic system, and the correlation between the VAS scores and nasal temperature before and after treatment was analyzed. The clinical effects of both groups were evaluated according to the VAS score.@*RESULTS@#The total effective rate in the observation group after treatment was 85.7% (30/35), which was higher than 71.9% in the control group (23/32, <0.05). After treatment and at follow-up, the VAS scores of both groups were lower than those before treatment (<0.05), and the VAS score of the observation group was lower than that of the control group at follow-up (<0.05). After treatment, the nasal temperature, pulmonary range, large intestinal range and renal range of the observation group were all lower than those before treatment (<0.05), the nasal temperature and nasal range of the control group were lower than before treatment (<0.05), and the reduction of nasal temperature, nasal range and renal range in the observation group was greater than that of the control group (<0.05). Before and after treatment, there was a correlation between VAS score and nasal temperature (<0.05).@*CONCLUSION@#The herb-separated moxibustion combining western medication has a better effect and long-term effect than western medication alone for moderate to severe persistent AR, which can improve heat variation on projected areas of the nose, lung, large intestine and kidney of patients. In addition, nasal temperature can reflect the severity of the symptoms of patients with moderate to severe persistent AR, or it can be used as a secondary indicator to evaluate condition of AR.

OBJECTIVE@#To study the incidence of acute attacks of asthma and dynamic changes in laboratory markers in children with well-controlled asthma after the withdrawal of low-dose inhaled corticosteroids (ICS), and to provide a basis for optimal long-term control regimens for children with asthma.@*METHODS@#A total of 63 children with well-controlled asthma were enrolled as subjects. According to their parents' wishes, they were continuously administered with ICS (ICS treatment group; n=35) and without ICS (ICS withdrawal group; n=28). They were followed up for 18 months. The incidence of acute attacks of asthma was evaluated, dynamic monitoring was performed for pulmonary function and fractional exhaled nitric oxide (FeNO), and childhood asthma control test (C-ACT) was performed every three months.@*RESULTS@#At 3, 6, 9, and 12 months of follow-up, there was no significant difference in FeNO between the ICS treatment and withdrawal groups (P>0.05). However, at 15 and 18 months of follow-up, the withdrawal group had a significantly higher level of FeNO than the ICS treatment group (P0.05). At 3, 6, 9, and 12 months of follow-up, there were no significant differences between the two groups in the percentage of forced expiratory volume in 1 second, the ratio of forced expiratory volume in 1 second to forced vital capacity, percentage of predicted maximum mid-expiratory flow (MMEF%), and maximal expiratory flow at 50% of vital capacity (MEF50) (P>0.05), while at 15 and 18 months of follow-up, the ICS treatment group had significantly higher MMEF% and MEF50 than the withdrawal group (P<0.05). During follow-up, 3 children (9%) in the ICS treatment group and 8 (29%) in the withdrawal group experienced acute attacks of asthma (P=0.0495).@*CONCLUSIONS@#Continuous inhalation of low-dose ICS can maintain the stability of pulmonary function and reduce acute attacks of asthma in children with well-controlled asthma.

Atopic dermatitis (AD) is a chronic inflammatory skin disease, and its prevalence is increasing. AD usually elicits skin barrier dysfunction, dry skin and itching. As the mechanisms of AD remain unknown, there is an urgent need to find effective therapies. Because of the diversity and complexity of marine environments, the discovery of drugs from marine organisms as novel therapeutic agents for human diseases has seen renewed interest. Dihydroaustrasulfone alcohol (WA-25), the synthetic precursor of austrasulfone, which is a natural product isolated from a Formosan soft coral, has been shown to possess many therapeutic effects in our previous studies. However, the detailed mechanisms and therapeutic effects of WA-25 on AD are incompletely understood. We performed in vitro and in vivo studies to examine the effects of WA-25 on AD. We showed that WA-25 blocks inflammation and oxidative stress. Simultaneously, we also found that WA-25 reduces the AD scores and AD-induced transepidermal water loss (TEWL), scratching behavior, and alloknesis. WA-25 is more effective in cases of AD than are the drugs that are currently used clinically. Importantly, we also found that when nucleophosmin (NPM) was inhibited or when its expression was reduced, the anti-inflammatory and anti-AD effects of WA-25 were blocked. These data suggest that NPM plays dual roles in inflammation and AD. Overall, these results suggest that WA-25 is a potential anti-inflammatory and AD therapeutic agent that is modulated by NPM.
