With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.

Objective: To investigate the clinical presentation and genetic characteristics of malignant infantile osteopetrosis. Methods: This was a retrospective case study. Thirty-seven children with malignant infantile osteopetrosis admitted into Beijing Children's Hospital from January 2013 to September 2022 were enrolled in this study. According to the gene mutations, the patients were divided into the CLCN7 group and the TCIRG1 group. Clinical characteristics, laboratory tests, and prognosis were compared between two groups. Wilcoxon test or Fisher exact test were used in inter-group comparison. The survival rate was estimated with the Kaplan-Meier method and the Log-Rank test was used to compare the difference in survival between groups. Results: Among the 37 cases, there were 22 males and 15 females. The age of diagnosis was 0.5 (0.2, 1.0) year. There were 13 patients (35%) and 24 patients (65%) with mutations in CLCN7 and TCIRGI gene respectively. Patients in the CLCN7 group had an older age of diagnosis than those in the TCIRGI group (1.2 (0.4, 3.6) vs. 0.4 (0.2, 0.6) years, Z=-2.60, P=0.008). The levels of serum phosphorus (1.7 (1.3, 1.8) vs. 1.1 (0.8, 1.6) mmol/L, Z=-2.59, P=0.010), creatine kinase isoenzyme (CK-MB) (457 (143, 610) vs. 56 (37, 82) U/L, Z=-3.38, P=0.001) and the level of neutrophils (14.0 (9.9, 18.1) vs. 9.2 (6.7, 11.1) ×10⁹/L, Z=-2.07, P=0.039) at diagnosis were higher in the CLCN7 group than that in the TCIRG1 group. However, the level of D-dimer in the CLCN7 group was lower than that in the TCIRGI group (2.7 (1.0, 3.1) vs. 6.3 (2.5, 9.7) μg/L, Z=2.83, P=0.005). After hematopoietic stem cell transplantation, there was no significant difference in 5-year overall survival rate between the two groups (92.3%±7.4% vs. 83.3%±7.6%, χ²=0.56, P=0.456). Conclusions: TCIRGI gene mutations are more common in children with osteopetrosis. Children with TCIRGI gene mutations have younger age, lower levels of phosphorus, CK-MB, and neutrophils and higher level of D-dimer at the onset. After hematopoietic stem cell transplantation, patients with CLCN7 or TCIRGI gene mutations have similar prognosis.

Abstract: Objective To investigate the current status of streptomycin resistance of Yersinia pestis caused by point mutations of rpsL gene in Qinghai, so as to provide theoretical basis for precise clinical medication and prevention of drug resistance of human plague outbreak in South area of Qinghai Province in the future. Methods A total of 104 representative strains of Yersinia pestis collected from plague patients, vector insects and intermediate hosts in South area of Qinghai Province from 1957 to 2009 were screened, isolated and cultured by Hiss agar plates. The DNA of representative Yersinia pestis was extracted by sodium dodecyl sulfate lysis and phenol-chloroform method. The primers forward primer and reverse primer and TaqMan-MGB probes probe1 [FAM] and probe2 [VIC] were designed for the rpsL gene of streptomycin resistance gene in China. Real-time PCR with TaqMan-MGB fluorescent probe was used to detect the mutations of rpsL gene in streptomycin resistance locus of 104 strains of Yersinia pestis in South area of Qinghai Province. Results The FAM test results of 104 strains in South area of Qinghai Province were positive, corresponding to the detection of rpsL (128 : A ), RFU peak >1 000,negative <200. VIC test results of all tested strains were negative, corresponding to the detection of rpsL (128:G), RFU peak <200, positive >1 000. That is, no strains with rpsL gene mutation related to streptomycin resistance were found in the 104 strains of Yersinia pestis in Qingnan Province. Conclusion This study provides basic data on the distribution of streptomycin resistance of Yersinia pestis in South area of Qinghai Province, and lays a foundation for preventing the occurrence of drug resistance and clinical treatment of Yersinia pestis in South area of Qinghai Province.

To explore the effect of Internet+diet self-management intervention technology on the blood pressure control of hypertension high-risk population through the intervention of hypertension high-risk population in Haikou City community, so as to provide scientific evidence for the prevention and treatment of cardiovascular diseases (CVD). The multi-stage cluster sampling method was used, and 295 hypertension high-risk participants were recruited from 15 communities in Haikou City from July to December 2021. The 15 communities were randomly divided into three groups: blank group, traditional group and Internet plus group by random number table method. The blank group referred to the group (99 participants) that did not take special intervention measures but the routine interventions in accordance with the "National Basic Public Health Service Standards (the Third Edition) Health Education Service Standards". On the basis of the blank group, the traditional group (95 participants) was intervened by giving additional traditional methods such as holding lectures and distributing popular science books. The Internet plus group (101 participants) was given additional Internet measures on the basis of the intervention of the traditional group. After 6 months, questionnaires, laboratory biochemical tests, and physical measurements were conducted. SPSS 25.0 software was applied for data analysis. Measurement data that followed normal distribution were statistically described by using mean±standard deviation, analysis of variance was used for inter group comparisons before intervention, analysis of covariance was used for inter group comparisons after intervention, and Bonferroni adjustment was used for pairwise comparisons between groups. Measurement data that did not follow the Normal distribution were represented by M (Q₁, Q₃). The rank sum test was used for inter group comparison. The k sample Kruskal Wallis single factor ANOVA was used to compare the distribution between different groups. Counting data were described by composition ratio or rate. Under the premise of balanced comparison between groups before intervention, Chi-squared test was used for inter group comparison after intervention, and Bonferroni adjustment method was used for pairwise comparison between groups. The results showed that a total of 295 participants were included, with males accounting for 35.6% (105) and females accounting for 64.4% (190). The age ranged from 55 to 74 years old, with an average age of (64.69±5.73) years. The number of married accounted for 95.6% (282 participants). There were no statistically significant differences in gender, age, family history, education level, occupation, marital status, drinking habits, regular exercise, dietary status, SBP (systolic blood pressure), DBP (diastolic blood pressure), pulse pressure difference, BMI (body mass index), folic acid, and 24-hour urine sodium among the three groups upon enrollment (P values>0.05). After the intervention, the drinking rate was as follows: Internet plus group (29, 28.7%)2=28.948, P<0.001); Regular exercise rate was higher in the Internet plus group (37, 36.6%) than in the traditional group (18, 18.9%) and the blank group (16, 16.2%) (χ²=13.476, P=0.001). After the intervention, compared with the participants in the blank group, the intake of energy, carbohydrate, dietary fiber, sodium and folic acid in the Internet plus group were significantly different (all P<0.05); Compared with the participants in the traditional group, the energy, carbohydrate and dietary fiber intake of the participants in the Internet plus group were significantly different (all P<0.05). After the intervention, the blood pressure levels in the Internet plus group [ SBP: (128.95±6.55) mmHg, DBP: (79.88±5.75) mmHg ] and the traditional group [ SBP: (129.63±8.41) mmHg, DBP: (79.77±7.73) mmHg ] were lower than those in the blank group [ SBP: (132.93±8.41) mmHg, DBP: (82.42±7.76) mmHg ] (SBP: F=9.417, P<0.001; DBP: F=6.967, P=0.001), the 24-hour urinary sodium level in the Internet plus group (143.63±38.58) mmol/24 h was lower than that in the traditional group (163.31±35.67) mmol/24 h and the blank group (154.14±35.52) mmol/24 h (F=11.509, P<0.001). In conclusion, compared with the traditional intervention mode, the "Internet plus diet self-management intervention" mode is more likely to promote the development of a healthy lifestyle for people at high risk of hypertension, effectively improve blood pressure and 24-hour urine sodium level, and facilitate CVD prevention.

Objective:To explore the strategies of reducing relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with high-risk myelodysplastic syndrome (MDS) from the perspectives of optimizing the conditioning regimen and pre-transplant cytoreductive therapy.Methods:A total of 84 patients with high-risk MDS undergoing allo-HSCT between January 2013 and September 2019 were retrospectively analyzed. Based upon preparative regimens, they were divided into two groups of decitabine intensified BUCY2 ( n=49) and BUCY2 regimen ( n=35), based upon whether or not pre-treatment prior to allo-HSCT: cytoredutive treatment ( n=34) and none ( n=50). Two groups were compared with regards to hematopoietic reconstitution, graft-versus-host disease (GVHD), relapse rate, transplant-related mortality (TRM) and survival. Results:No significant inter-group differences existed in hematopoietic reconstitution or acute/chronic GVHD. The relapse rate was significantly lower in decitabine intensified group than that in BUCY2 group (18.7% vs 40.0%, P=0.025). Survival was significantly better in decitabine intensified group than that in BUCY2 group (3-year OS: 71.3% vs 51.2%, P=0.038; 3-year DFS: 65.3% vs 45.2%, P=0.033). Moreover, the incidence of recurrence was markedly lower in pre-transplant treatment group than that in non-treatment group (20.7% vs 38.9%, P=0.035). The inter-group incidence of TRM was not different. Three-year OS/DFS of treatment group were remarkably superior to those of non-treatment group (71.2% vs 50.8%, P=0.024; 64.7% vs 45.9%, P=0.044). Conclusions:As an optimal conditioning regimen for high-risk MDS, decitabine intensified BUCY2 regimen could better eliminate tumor burden, remarkably lower relapse rate and improve OS after allo-HSCT. In addition, pre-transplant treatment significantly reduces relapse and offers benefit for OS after allo-HSCT. Therefore intensified conditioning regimen and pre-transplant treatment may be promising strategies of reducing relapse and improving survival for high-risk MDS. However, it still needs further confirmation from prospective randomized controlled trials.

Objectives To investigate whether a longer time period of gadolinium ethoxybenzyl diethylenetriaminepen-taacetic acid (Gd-EOB-DTPA)-enhanced T1 mapping scanning, as well as dynamic contrast-enhanced (DCE) and multiple hepatobiliary phase magnetic resonance imaging (MRI) have the potential to provide information about liver function in rats with liver fibrosis. Methods Forty rats were divided into the carbon tetrachloride-induced hepatic injury groups [carbon tetrachloride for four (

Objective To investigate the role of histone deacetylase 3 ( HDAC3 ) inhibitor (HDAC3I) in hypoxia-reoxygenation( H/R) injury of PC12 cells. Methods H/R cell injury model was established by using PC 12 cells for 4 hours hypoxia and then reoxygenation for 24 hours. HDAC3I treatment group was pretreated with RGFP966 for 1 hour and then subjected to hypoxia-reoxygenation injury. The experiment was divided into three groups: normal control group, model group and HDAC3I treatment group, and 3 repetitions for each group. Cell viability was determined using MTT. Cellulose dehydrogenase (LDH) was detected by colorimetry. Flow cytometry was used to detect apoptosis and intracellular reactive oxygen species ( ROS ), respectively. The activity of superoxide dismutase ( SOD ) was determined by xanthine oxidase method. The malondialdehyde ( MDA ) content was determined by the thiobarbituric acid method. Western blotting was used to detect the expression of Bax, Bcl-2, cleaved-Caspase-3 and HDAC3 proteins. Results Compared with the control group, the cell viability of the model group and HDAC3I treatment group decreased significantly (P<0. 05), and the cell LDH (P<0. 05) and apoptosis (P<0. 05) increased significantly. The cell viability of HDAC3I treatment group was significantly higher than that of the model group (P<0. 05), while the LDH (P<0. 05) and apoptosis of HDAC3I treatment group were lower than the model group (P<0. 05). In addition, compared with the control group, the ROS and MDA (P< 0. 05 ) of the model group and the HDAC3I treatment group increased significantly, and the SOD decreased significantly (P<0. 05). ROS and MDA in the HDAC3I treatment group (P<0. 05) were significantly lower than the model group, while the SOD level was higher than the model group (P< 0. 05). Western blotting analysis showed that compared with the control group, Bax and cleaved-Caspase-3 in the model group and HDAC3I treatment group increased significantly, and Bcl-2 decreased significantly (P<0. 05). The Bax and cleaved-Caspase-3 in the HDAC3I treatment group were significantly lower than the model group, and Bcl-2 was significantly higher than the model group (P<0. 05). Compared with the control group, the expression of HDAC3 protein in the model group increased significantly (P<0. 05), while the HDAC3 protein in the HDAC3I treatment group decreased significantly (P<0. 05). Conclusion HDAC3I reduces PC 12 cell apoptosis induced by hypoxia/reoxygenation by reducing oxidative stress.

Fifteen 9-substituted palmatine (1) derivatives were synthesized and evaluated for their anti-Helicobacter pylori (Hp) activities in vitro. Structure-activity relationship studies revealed that introducing appropriate substituted secondary amino group at position 9 of lead 1 might be beneficial for potency. Among them, compound 5a showed the most potential activity against metronidazole (Met) resistant Hp isolates with minimal inhibitory concentrations (MICs) of 4 μg·mL^-1, much better than that of lead 1. Compound 5a displayed satisfactory safety profile in acute toxicity assay. Molecular docking suggested that 5a might act on Hp urease. The results provided key scientific evidence for the development of 1 derivatives into a new class of anti-Hp component.

Purpose: This study aimed to investigate the potential systemic antitumor effects of stereotactic ablativeradiotherapy (SABR) and apatinib (a novel vascular endothelial growth factor receptor2 inhibitor) via reversing the immunosuppressive tumor microenvironment for lung carcinoma. Materials and Methods: Lewis lung cancer cells were injected into C57BL/6 mice in the left hindlimb (primary tumor;irradiated) and in the right flank (secondary tumor; nonirradiated). When both tumors grewto the touchable size, mice were randomly divided into eight treatment groups. These groupsreceived normal saline or three distinct doses of apatinib (50 mg/kg, 150 mg/kg, and 200mg/kg) daily for 7 days, in combination with a single dose of 15 Gy radiotherapy or not tothe primary tumor. The further tumor growth/regression of mice were followed andobserved. Results: For the single 15 Gy modality, tumor growth delay could only be observed at the primarytumor. When combining SABR and apatinib 200 mg/kg, significant retardation of both primaryand secondary tumor growth could be observed, indicated an abscopal effect wasinduced. Mechanism analysis suggested that programmed death-ligand 1 expressionincreased with SABR was counteract by additional apatinib therapy. Furthermore, whenapatinib was combined with SABR, the composition of immune cells could be changed.More importantly, this two-pronged approach evoked tumor antigen–specific immune responsesand the mice were resistant to another tumor rechallenge, finally, long-term survivalwas improved. Conclusion Our results suggested that the tumor microenvironment could be managed with apatinib,which was effective in eliciting an abscopal effect induced by SABR.
