ABSTRACT

Early childhood caries (ECC) is a significant chronic disease of childhood and a rising public health burden worldwide. ECC may cause a higher risk of new caries lesions in both primary and permanent dentition, affecting lifelong oral health. The occurrence of ECC has been closely related to the core microbiome change in the oral cavity, which may be influenced by diet habits, oral health management, fluoride use, and dental manipulations. So, it is essential to improve parental oral health and awareness of health care, to establish a dental home at the early stage of childhood, and make an individualized caries management plan. Dental interventions according to the minimally invasive concept should be carried out to treat dental caries. This expert consensus mainly discusses the etiology of ECC, caries-risk assessment of children, prevention and treatment plan of ECC, aiming to achieve lifelong oral health.

ABSTRACT

The bile acid-responsive G-protein-coupled receptor TGR5 is expressed in monocytes and macrophages, and plays a critical role in regulating inflammatory response. Our previous work has shown its role in promoting the progression of non-small cell lung cancer (NSCLC), yet the mechanism remains unclear. Here, using Tgr5-knockout mice, we show that TGR5 is required for M2 polarization of tumor-associated macrophages (TAMs) and suppresses antitumor immunity in NSCLC via involving TAMs-mediated CD8+ T cell suppression. Mechanistically, we demonstrate that TGR5 promotes TAMs into protumorigenic M2-like phenotypes via activating cAMP-STAT3/STAT6 signaling. Induction of cAMP production restores M2-like phenotypes in TGR5-deficient macrophages. In NSCLC tissues from human patients, the expression of TGR5 is associated with the infiltration of TAMs. The co-expression of TGR5 and high TAMs infiltration are associated with the prognosis and overall survival of NSCLC patients. Together, this study provides molecular mechanisms for the protumor function of TGR5 in NSCLC, highlighting its potential as a target for TAMs-centric immunotherapy in NSCLC.

ABSTRACT

OBJECTIVES@#To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China.@*METHODS@#A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined.@*RESULTS@#The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05).@*CONCLUSIONS@#It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

ABSTRACT

Glucosyltransferases (Gtfs) play critical roles in the etiology and pathogenesis of Streptococcus mutans (S. mutans)- mediated dental caries including early childhood caries. Gtfs enhance the biofilm formation and promotes colonization of cariogenic bacteria by generating biofilm extracellular polysaccharides (EPSs), the key virulence property in the cariogenic process. Therefore, Gtfs have become an appealing target for effective therapeutic interventions that inhibit cariogenic biofilms. Importantly, targeting Gtfs selectively impairs the S. mutans virulence without affecting S. mutans existence or the existence of other species in the oral cavity. Over the past decade, numerous Gtfs inhibitory molecules have been identified, mainly including natural and synthetic compounds and their derivatives, antibodies, and metal ions. These therapeutic agents exert their inhibitory role in inhibiting the expression gtf genes and the activities and secretion of Gtfs enzymes with a wide range of sensitivity and effectiveness. Understanding molecular mechanisms of inhibiting Gtfs will contribute to instructing drug combination strategies, which is more effective for inhibiting Gtfs than one drug or class of drugs. This review highlights our current understanding of Gtfs activities and their potential utility, and discusses challenges and opportunities for future exploration of Gtfs as a therapeutic target.

ABSTRACT

OBJECTIVE:To reeval uate the systematic review/Meta-analy sis of efficacy and safety of eplerenone in the treatment of essential hypertension. METHODS :Retrieved from PubMed ,Embase,Cochrane Library ,Web of Science ,Wanfang database,CNKI,VIP,systematic review/Meta-analysis about eplerenone in the treatment of essential hypertension were collected from the inception to June 24th,2021. After literature screening and data extraction ,the quality of included literatures were evaluated with PRISMA statement ;methodology quality of included literatures were evaluated with AMSTAR 2 scale;GRADE method was adopted to evaluate the evidence quality of outcome measures. Efficacy and safety index evaluation of included literatures were summeried. RESULTS :A total of 8 systematic reviews/Meta-analyses were included ,involving 5 systematic reviews and 3 Meta-analysis,including 73 outcome indicators. PRISMA scores ranged from 7.5 to 23.5,including 6 literatures (75.0%)with≤15 points,1(12.5%)with >15-<21 points and 1(12.5%)with ≥21 points. The results of AMSTAR 2 evaluation indicated that the methodological quality of 2 studies was low ,and that of 6 studies was very low . GRADE quality evaluation results showed that there were 3 high quality indicators ,24 medium quality indicators and 46 low or very low quality indicators;the factors contributed to downgrading evidence quality were limitation ,inconsistency,imprecision and publication bias. In terms of efficacy ,compared with placebo ,eplerenone could significantly reduce clinical blood pressure (CBP)and 24-hour ambulatory blood pressure (ABP). Its effect in reducing CBP was significantly better than other antihypertensive drugs or equivalent to other antihypertensive drugs. The effects of eplerenone on reducing clinical systolic blood pressure was not as good as spironolactone and enalapril ,or bett er than calcium channel blocker ,enalapril and angiotensin receptor antag onist,or equivalent to calcium channel blocker and enalapril ;the effect of eplerenone on reducing clinical diastolic blood pressure was not as good com as spironolactone ,calcium c hannel blocker and enalapril ,or as good as enalapril ,but better than angiotensin receptor antagonist. In terms of safety ,there was no significant difference in the incidence of ADR ,serious ADR or hyperkalemia caused by eplerenone ,compared with placebo ,or the incidence of ADR was higher than that of placebo. There was no statistical significance in the incidence of ADR or serious ADR ,compared with other antihypertensive drugs. CONCLUSIONS :Efficacy and safety of eplerenone in the treatment of essential hypertension was good ,but in view of the poor methodological quality of systematic reviews or Meta-analysis and the low or very low level of outcome indicator evidence ,the authenticity and effectiveness of the conclusion will be reduced ,so that those indcaters should be interpreted carefully.

ABSTRACT

Background/Aims@#MicroRNAs (miRNAs) play critical regulatory roles in the pathogenesis of pulmonary fibrosis. The aim of this study was to explore whether miRNA antagomirs could serve as potential therapeutic agents in interstitial lung diseases. @*Methods@#A mouse model of pulmonary fibrosis was established by intratracheal injection of bleomycin (BLM). Using microarray analysis, up-regulated miRNAs were identified during the development of pulmonary fibrosis. miR-155 was chosen as the candidate miRNA. Fifteen mice were then randomized into the following three groups: BLM + antagomiR-155 group, treated with BLM plus intravenously injected with antagomiR-155; BLM group, treated with intratracheal BLM plus phosphate-buffered saline (PBS); and a control group, treated with PBS only. Lung tissues were collected for histopathological analysis, hydroxyproline measurement, and Western blotting. Enzyme-linked immunosorbent assays were used for the measurement of cytokines associated with pulmonary fibrosis. @*Results@#Histological changes and hydroxyproline levels induced by BLM were significantly inhibited by antagomiR-155. The levels of interleukin 4 (IL-4) and transforming growth factor-β (TGF-β) expression were increased after BLM treatment. However, miR-155 silencing decreased the expression of IL-4, TGF-β, and interferon-γ. TGF-β-activated kinase 1/mitogen-activated protein kinase kinase kinase 7 (MAP3K7)-binding protein 2 (TAB2) of the mitogen-activated protein kinase (MAPK) signaling pathway, was activated by BLM and inhibited by in vivo silencing of miR-155 via antagomiR-155. @*Conclusions@#In vivo treatment with antagomiR-155 alleviated the pathological changes induced by BLM and may be a promising therapeutic strategy for pulmonary fibrosis.

ABSTRACT

OBJECTIVE@#This study aimed to evaluate the postoperative complications undergoing dental general anesthesia in children and analyze the prevalence and related factors.@*METHODS@#This prospective study involved 292 systematically healthy children (36 to 71 months old) who received extensive dental treatment under general anesthesia. Data about patients' histories, characteristics, dental and anesthesia procedure were collected. Parents or caregivers were interviewed face to face preoperation and 72 h postoperation. Data were analyzed using logistic regression.@*RESULTS@#Approximately 93.5% of the enrolled children reported one or more complications. The most prevalent complication was postoperative pain, followed by weariness, agitation, problem in eating, drowsiness, oral bleeding, cough, fever, etc. The length of operative time and femininity were the risks of the postoperative pain. Nutrition status was the factor probably in association with fever.@*CONCLUSIONS@#The children receive longer operative time and girls show to be more susceptible to the postoperative pain. High nutrition status could be the protective factor of postoperative fever.

ABSTRACT

Background@#No currently available biomarkers or treatment regimens fully meet therapeutic needs of type 1 diabetes mellitus (T1DM). Circular RNA (circRNA) is a recently identified class of stable noncoding RNA that have been documented as potential biomarkers for various diseases. Our objective was to identify and analyze plasma circRNAs altered in T1DM. @*Methods@#We used microarray to screen differentially expressed plasma circRNAs in patients with new onset T1DM (n=3) and age-/gender-matched healthy controls (n=3). Then, we selected six candidates with highest fold-change and validated them by quantitative real-time polymerase chain reaction in independent human cohort samples (n=12). Bioinformatic tools were adopted to predict putative microRNAs (miRNAs) sponged by these validated circRNAs and their downstream messenger RNAs (mRNAs). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed to gain further insights into T1DM pathogenesis. @*Results@#We identified 68 differentially expressed circRNAs, with 61 and seven being up- and downregulated respectively. Four of the six selected candidates were successfully validated. Curations of their predicted interacting miRNAs revealed critical roles in inflammation and pathogenesis of autoimmune disorders. Functional relations were visualized by a circRNA-miRNA-mRNA network. GO and KEGG analyses identified multiple inflammation-related processes that could be potentially associated with T1DM pathogenesis, including cytokine-cytokine receptor interaction, inflammatory mediator regulation of transient receptor potential channels and leukocyte activation involved in immune response. @*Conclusion@#Our study report, for the first time, a profile of differentially expressed plasma circRNAs in new onset T1DM. Further in silico annotations and bioinformatics analyses supported future application of circRNAs as novel biomarkers of T1DM.

ABSTRACT

Background@#The detection of glutamic acid decarboxylase 65 (GAD65) autoantibodies is essential for the prediction and diagnosis of latent autoimmune diabetes in adults (LADA). The aim of the current study was to compare a newly developed electrochemiluminescence (ECL)-GAD65 antibody assay with the established radiobinding assay, and to explore whether the new assay could be used to define LADA more precisely. @*Methods@#Serum samples were harvested from 141 patients with LADA, 95 with type 1 diabetes mellitus, and 99 with type 2 diabetes mellitus, and tested for GAD65 autoantibodies using both the radiobinding assay and ECL assay. A glutamic acid decarboxylase antibodies (GADA) competition assay was also performed to assess antibody affinity. Furthermore, the clinical features of these patients were compared. @*Results@#Eighty-eight out of 141 serum samples (62.4%) from LADA patients were GAD65 antibody-positive by ECL assay. Compared with ECL-GAD65 antibody-negative patients, ECL-GAD65 antibody-positive patients were leaner (P<0.0001), had poorer β-cell function (P<0.05), and were more likely to have other diabetes-associated autoantibodies. The β-cell function of ECLGAD65 antibody-positive patients was similar to that of type 1 diabetes mellitus patients, whereas ECL-GAD65 antibody-negative patients were more similar to type 2 diabetes mellitus patients. @*Conclusion@#Patients with ECL-GAD65 antibody-negative share a similar phenotype with type 2 diabetes mellitus patients, whereas patients with ECL-GAD65 antibody-positive resemble those with type 1 diabetes mellitus. Thus, the detection of GADA using ECL may help to identify the subtype of LADA.

ABSTRACT

Pediatric dentistry should focus not only on the treatment of various oral diseases during the entire growth and development of children but also on the early prevention, diagnosis, and intervention of various oral diseases in this process. Early identification and removal of risk factors or early intervention for common oral diseases is necessary to the implementation of oral health management for pregnant women, infants, preschool and school-age children, and adolescents with different general and oral physiological characteristics and common oral diseases. The treatment enables the growth and development of the teeth, as well as occlusion and facials along the normal trajectory, ultimately achieving the functional perfection and aesthetic coordination of the cranio-maxillary and occlusion.

ABSTRACT

Malocclusion is a worldwide dental problem that influences the affected individuals to varying degrees. Many factors contribute to the anomaly in dentition, including hereditary and environmental aspects. Dental caries, pulpal and periapical lesions, dental trauma, abnormality of development, and oral habits are most common dental diseases in children that strongly relate to malocclusion. Management of oral health in the early childhood stage is carried out in clinic work of pediatric dentistry to minimize the unwanted effect of these diseases on dentition. This article highlights these diseases and their impacts on malocclusion in sequence. Prevention, treatment, and management of these conditions are also illustrated in order to achieve successful oral health for children and adolescents, even for their adult stage.
