Objective: To construct an evaluation index system of oral health literacy for children's parents, so as to provide an index system for the evaluation of oral health literacy for children's parents in China. Methods: The evaluation index system of oral health literacy for children's parents was designed based on literature review and semi-structured interview. Experts from oral prevention and pediatric oral medicine were invited to participate in two-round Delphi consultations. The indicators were scored and screened according to the importance, and the weight determined using analytic hierarchy process. The effectiveness of the consultation was evaluated by positive coefficient, authority coefficient and coordination coefficient. Results: Twenty-four experts participated in the consultation, including 6 males and 18 females. There were 21 experts with a master degree, 3 experts with a doctor degree, and 20 experts with vice senior professional titles and above. The recovery rates of the two rounds of consultations were 96.00% and 100.00%, the authority coefficients were 0.866 and 0.917, the Kendall's coefficient of concordance were 0.120 and 0.156 (both P<0.05), and the coefficient of variation was 0.15-0.38 and 0.03-0.17, respectively. The final evaluation index system included 3 primary indicators, 11 secondary indicators and 40 tertiary indicators. The primary indicators were basic knowledge and concepts related to oral health, promoting lifestyle and behaviors related to oral health, and maintaining basic skills related to oral health. Conclusion The evaluation index system of oral health literacy for children's parents has been established in this study and needs to be further applied and evaluated.

Aim To study the anti-inflammatory activ¬ity of diterpenes from Tripterygium wilfordii on lipopo- lysaccharide ( LPS)-induced macrophage and its mech¬anism. Methods MTT assay was used to detect the cytotoxicity of compounds. The Griess method was used to detect the NO on LPS-induced RAW264. 7 cells. ELISA was applied to determine the contents of inter- leukin 6 (IL-6) , tumor necrosis factor a ( TNF-a ) , interleukin lp (IL-lfj) and interleukin 18 (IL-18) in cell culture supernatant. Western blot was used to de¬tect IkBcx, .INK, ERK, p38, STAT3 and their phos-phorylation in LPS-induced RAW264.7, as well as the effect on COX-2, iNOS, NLRP3, caspase-1 , cleaved- caspase-1. Flow cytometry was employed to detect the effects of compounds on the phagocytosis of RAW 264. 7 cells. Results Hypoglicin II (1) and ent-pimara-8 (14) , 15-diene-19-ol (6) , two diterpenoid compounds from Tripterygium wilfordii could effectively inhibit the expression of inflammatory mediators ( COX-2 and iN- OS) and inflammatory cytokines (IL-6, IL-lp, IL- 18) in LPS-induced RAW264. 7 cells. Further re¬search found that the phosphorylation of IkBcx , JNK, ERK, P38, STAT3 and NLRP3 was all inhibited; however, there was no significant effect on the expres¬sion of IkBcx, JNK, ERK, P38 and STAT3. At the same time, they also inhibited the phagocytosis of mac-rophages. Conclusions The anti-inflammatory mecha¬nism of Tripterygium wilfordii diterpenoids 1 and 6 might be through inhibiting the production of NLRP3 inflammatory bodies, inflammatory mediators (COX-2 and iNOS) and inflammatory cytokines (IL-6, IL-lp and IL-18) , which is closely related to inhibiting the activation of MAPK, NF-kB and STAT3 pathway.

The results of the fourth National Oral Health Epidemiology Survey showed that the caries rates of permanent teeth of 12-year-old children and deciduous teeth of 5-year-old children were 34.5% and 70.9%, respectively, which are significantly higher than those of 10 years ago. Parents ' oral health literacy plays a decisive role in children 's oral health and oral related quality of life. This paper reviews the related concepts and significance of oral health literacy of children 's parents, Framework to Foster Oral Health Literacy and Oral/General Health Integration, assessment tools of oral health literacy, the status and influencing factors of parents ' oral health literacy, the effect of parents ' oral health literacy on children 's oral health and the strategies of improving parents ' oral health literacy, so as to provide reference for improving the oral health literacy of children 's parents.

Although the functions of metabolic enzymes and nuclear receptors in controlling physiological homeostasis have been established, their crosstalk in modulating metabolic disease has not been explored. Genetic ablation of the xenobiotic-metabolizing cytochrome P450 enzyme CYP2E1 in mice markedly induced adipose browning and increased energy expenditure to improve obesity. CYP2E1 deficiency activated the expression of hepatic peroxisome proliferator-activated receptor alpha (PPARα) target genes, including fibroblast growth factor (FGF) 21, that upon release from the liver, enhanced adipose browning and energy expenditure to decrease obesity. Nineteen metabolites were increased in Cyp2e1-null mice as revealed by global untargeted metabolomics, among which four compounds, lysophosphatidylcholine and three polyunsaturated fatty acids were found to be directly metabolized by CYP2E1 and to serve as PPARα agonists, thus explaining how CYP2E1 deficiency causes hepatic PPARα activation through increasing cellular levels of endogenous PPARα agonists. Translationally, a CYP2E1 inhibitor was found to activate the PPARα-FGF21-beige adipose axis and decrease obesity in wild-type mice, but not in liver-specific Ppara-null mice. The present results establish a metabolic crosstalk between PPARα and CYP2E1 that supports the potential for a novel anti-obesity strategy of activating adipose tissue browning by targeting the CYP2E1 to modulate endogenous metabolites beyond its canonical role in xenobiotic-metabolism.

To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.

Objective To investigate the activation of nuclear factor-B (NF-B)and hypoxia-inducible factor-1 (HIF-1)in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods Subjects were classified into mild-to-moderate OSHAS group (n = 16), severe OSAHS group (n = 14) and the matched control group (n=30). Gene and protein expressions of NF-B and HIF-1 were measured by RT-PCR, Western blot in peripheral blood mononuclear cells (PBMC). Results NF-κB p65 mRNA and NF-κB p65 protein,HIF-1α mRNA and HIF-1α protein in PBMC were significantly higher in severe OSAHS group than those in mild–to-moderate group and control group (P<0.01). But there were no significant difference in NF-κB p65 mRNA and NF-κB p65 protein between mild-to-moderate group and control group (P=0.068, P=0.254 respectively). Only gene (P<0.05) not the protein (P=0.777) of HIF-1αwas higher in mild-to-moderate as compared with control group. Both NF-κB p65 mRNA and HIF-1αmRNA were positively correlated with AHI (r=0.493, P=0.006, r=0.508, P=0.004), while negatively correlated with nighttime lowest blood oxygen saturation (LSaO2)(r=-0.488, P=0.006, r=-0.46, P=0.011). There was a positive correlation between NF-κB p65 protein level and AHI (r=0.669, P<0.001). HIF-1αprotein level was positively correlated with AHI, ODI (r=0.628, P=0.001;r=0.480, P=0.018). There were positive correlations between NF-κBp65mRNA and HIF-1αmRNA (r=0.543, P=0.002), NF-κBp65 and HIF-1αprotein respectively (r=0.716, P<0.001). Conclusions As the gene and protein of NF-κB and HIF-1 were up-regulated in patients with OSAHS, and also positively correlated with the severity of sickness. We conclude that both NF-κB and HIF-1 were involed in the pathogenesis of OSAHS.

OBJECTIVETo investigate the medium-term curative effects of locking proximal humerus plate for the treatment of comminuted fractures of proximal humerus, and provide evidences for the clinical practice.

METHODSFrom August 2005 and April 2008, 23 patients with comminuted fractures of proximal humerus were treated with locking plates, including 12 males and 11 females, aged 27 to 76 years old (averaged 51.5 years old). There were 18 cases of traffic accident injuries, 4 cases of falls injuries, and 1 case injured after heavy pressure. According to Neer classification, 11 cases were three-part fractures, and 12 cases were four-part fractures. Outcomes were assessed with radiography and the Constant-Murley (C-M) shoulder evaluation.

RESULTSAll the patients got primary healing of incisions. Twenty-three patients were followed up, and the duration ranged from 17 to 49 months, with an average of 35.25 months. Twenty patients had fracture healing during 4 to 7 months after operation. There was no significant differences among 3, 6 and 12 months after operation in C-M scoring. The average C-M score was (79.85 +/- 17.23) points (38 to 100 points) at the 12th month after operation, 8 cases got an excellent result, 8 good, 5 fair, and 2 poor. In the LPHP plus bone graft group 6 cases got an excellent result, 4 good, 3 fair, and 1 poor; in LPHP fixation group 2 excellent, 4 good, 2 fair,and 1 poor.

CONCLUSIONThe medium-term curative effect of the locking proximal humerus plate in the treatment of proximal humeral fractures is significant. For the comminuted fractures of proximal humerus combined with osteoporosis and bone defects, bone graft should be performed routinely.

Objective To evaluate the influence of nuclear factor (NF)-κB activation in peripheral blood mononuclear cells (PBMCs) on vascular inflammation in elderly patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods The 40 elderly subjects (≥65years old) were classed into control, mild, moderate and severe groups (n = 10, respectively)according to polysomnography (PSG). After PSG, the samples of peripheral venous blood were collected, and PBMCs were isolated. Nuclear protein was extracted and NF-κB was measured by Western blotting. ELISA was applied to measure the levels of TNF-α and IL-6 in serum. Blood samples from 10 cases (moderate 5 and severe 5) were measured again after four weeks of continuous positive airway pressure (CPAP) treatment. Results The expression of NF-κB in PBMCs and the concentration of TNF-α in serum were significantly increased in severe and moderate OSAHS patients compared with controls (P＜0. 05). The NF-κB expression was positively correlated with AHI (r=0. 617, P＜ 0. 001) and TNF-α concentration (r = 0. 498, P＜ 0. 001 ), negatively correlated with LSaO2 (r= -0. 548, P＜0. 001), and not correlated with IL-6 concentration (r=0. 365, P=0. 201).The CPAP treatment could significantly inhibit NF-κB activation in PBMCs and reduce TNF-αexcretion (P＜0.05, respectively). Conclusions PBMCs may play an important role in vascular endothelial injury through NF-κB expression and TNF-α excretion in elderly OSAHS patients, which is closely associated with the severity of the syndrome and night hypoxemia. CPAP treatment can inhibit the pathophysiologic process effectively.
