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.

To clarify the species, pathogenicity, and distribution of the pathogens causing the root rot of Atractylodes lancea in Hubei province, the tissue separation method was used to isolate the pathogens from root rot samples in the main planting areas of A. lancea in Hubei. Based on the preliminary identification of the Fusarium genus by the internal transcribed spacer(ITS) sequence, three housekeeping genes, EF1/EF2, Btu-F-FO1/Btu-F-RO1, and FF1/FR1, were amplified and sequenced. Subsequently, a phylogenetic tree was constructed based on these TEF gene sequences to classify the pathogens. The pathogenicity of these strains was determined using the root irrigation method. A total of 194 pathogen strains were isolated using the tissue separation method. Molecular identification using the three housekeeping genes identified the pathogens as F. solani, F. oxysporum, F. commune, F. equiseti, F. tricinctum, F. redolens, F. fujikuroi, F. avenaceum, F. acuminatum, and F. incarnatum. Among them, F. solani and F. oxysporum were the dominant strains, widely distributed in multiple regions, with F. solani accounting for approximately 54% of the total isolated strains and F. oxysporum accounting for approximately 34%. Other strains accounted for a relatively small proportion, totaling approximately 12%. The results of pathogenicity determination showed that there were certain differences in pathogenicity among strains. The analysis of the pathogenicity differentiation of the widely distributed F. solani and F. oxysporum strains revealed that these dominant strains in Hubei were mainly highly pathogenic. This study determined the species, pathogenicity, and distribution of the pathogens causing the root rot of A. lancea in Hubei province. The results provide a scientific basis for further understanding the root rot of A. lancea and its epidemic occurrence and scientifically preventing and controlling this disease.

OBJECTIVE: To explore the safety and efficacy of high-dose etoposide (VP-16) combined with recombinant human granulocyte colony-stimulating factor (rhG-CSF) as salvage mobilization for peripheral blood stem cells (PBSC) in newly diagnosed multiple myeloma (NDMM) patients. METHODS: From April 2021 to May 2023, eight NDMM patients who had failed to yield sufficient PBSC during initial mobilization with high-dose cyclophosphamide (CTX) combined with rhG-CSF underwent salvage mobilization with 1.2 g/m2 etoposide combined with rhG-CSF 10 μg/(kg·d). The effects and adverse reactions of initial mobilization and salvage mobilization were analyzed. RESULTS: For salvage mobilization and initial mobilization, the numbers of PBSC collections were 16 and 18, respectively. The mean value of total collected CD34⁺ cells were (11.90±5.75)×10⁶/kg and (1.67±0.75)×10⁶/kg (P =0.0010) in salvage mobilization group and initial mobilization group, respectively. The proportion of patients with a total collection of CD34⁺ cell count≥2×10⁶/kg were 100% and 37.5% (P =0.0625), and the proportion of patients with a total collection of CD34⁺ cell count≥5×10⁶/kg were 87.5% and 0% (P =0.0156) in salvage mobilization group and initial mobilization group, respectively. For five patients who underwent high-dose CTX initial mobilization but had a total CD34⁺ cell count < 2×10⁶/kg, successful collection was achieved through salvage mobilization with high-dose VP-16. Salvage mobilization with high-dose VP-16 was scheduled 2-3 weeks after failure of CTX mobilization. Adverse reactions of high-dose VP-16 mobilization did not increase compared to the initial mobilization with high-dose CTX. CONCLUSION As a salvage mobilization regimen, VP-16 1.2 g/m² combined with rhG-CSF is safe and highly effective in NDMM patients who failed to initial mobilization with high-dose CTX combined with rhG-CSF.

Objective To investigate the attributable risk(AR)of Acinetobacter baumannii(AB)infection in criti-cally ill patients.Methods A multicenter retrospective cohort study was conducted among adult patients in inten-sive care unit(ICU).Patients with AB isolated from sterile body fluid and confirmed with AB infection in each cen-ter were selected as the infected group.According to the matching criteria that patients should be from the same pe-riod,in the same ICU,as well as with similar APACHE Ⅱ score(±5 points)and primary diagnosis,patients who did not infect with AB were selected as the non-infected group in a 1:2 ratio.The AR was calculated.Results The in-hospital mortality of patients with AB infection in sterile body fluid was 33.3％,and that of non-infected group was 23.1％,with no statistically significant difference between the two groups(P=0.069).The AR was 10.2％(95％CI:-2.3％-22.8％).There is no statistically significant difference in mortality between non-infected pa-tients and infected patients from whose blood,cerebrospinal fluid and other specimen sources AB were isolated(P＞0.05).After infected with AB,critically ill patients with the major diagnosis of pulmonary infection had the high-est AR.There was no statistically significant difference in mortality between patients in the infected and non-infec-ted groups(P＞0.05),or between other diagnostic classifications.Conclusion The prognosis of AB infection in critically ill patients is highly overestimated,but active healthcare-associated infection control for AB in the ICU should still be carried out.

Gallbladder carcinoma,a relatively rare malignancy within the biliary tract,presents a grave prognosis primarily due to asymptomatic early stages leading to advanced stage diagnosis and the absence of efficacious treatment options.Research has identified chronic inflammation,predom-inantly caused by gallstones,as a critical etiological factor.While surgical intervention offers potential curative outcomes in early stages,the majority of cases are identified too late for optimal surgical outcomes.Chemotherapy and targeted therapy,despite offering new therapeutic avenues,have not significantly improved overall survival rates.Thus,understanding the pathogenesis of gallbladder cancer,especially its association with key genetic and molecular pathways,is imperative for devising novel therapeutic strategies.This review delineates the epidemiology,pathogenesis,current treat-ment modalities,and research advancements in gallbladder cancer,aiming to provide innovative in-sights for clinical management and guide future research endeavors.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

Objective To establish a rapid high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS)method for the determination of linezolid and vancomycin in trace plasma/serum from pediatric patients with severe infection.Methods The plasma/serum specimens(10 μL)were precipitated by methanol,then the supernatant was injected for detection directly.The internal standards were linezolid-D3 and norvancomycin.The chromatographic separation was performed with gradient elution on a Kinetex? EVO C18 column(30.0 mm × 2.1 mm,2.6 μm)using water and acetonitrile,each containing 0.1％formic acid,as mobile phase.The flow rate was 0.5 mL·min-1 and column temperature was 40 ℃.The injection volume was 2 μL and the total run time was 2 min.For mass spectrometry,electrospray ionization source was chosen,positive ion monitoring was used with multi-reaction monitoring(MRM)mode.The selectivity,lower limit of quantification(LLOQ)& calibration curve,accuracy & precision,recovery,matrix effect,stability,cross detection of plasma and serum samples,evaluation of hemolytic and hyperlipidemic effect were investigated.Results The retention times of linezolid,vancomycin,internal standard linezolid-D3 and norvancomycin were 1.18,1.03,1.17 and 1.01 min,respectively.The calibration curves of linezolid and vancomycin were y=8.95 × 10-1x+3.49 × 10-3(r=0.997 1)and y=3.13 × 10-1x+6.93 × 10-2(r=0.997 4),with the linear ranges of 0.2-25.6 μg·mL-1 and 1-128 μg·mL-1,and the lower limits of quantification were 0.2 μg·mL-1 and 1 μg·mL-1,respectively.The intra-run and inter-run precisions relative standard deviation(RSD)were both less than 9.55％.The average extraction recoveries of the two drugs were 96.24％-104.57％.The RSDs of internal standards-normalized matrix effect were no more than 7.58％.Plasma and serum matrix samples could be cross-detected.The maximum tolerable hemolysis degree of linezolid and vancomycin were 2％and 5％,respectively,and the hyperlipidemic effect did not affect the quantitation.The stability of the samples was good under test conditions.This method was successfully applied to the analysis of plasma samples from 28 pediatric patients with severe infection in our hospital.Conclusion This assay is sample-saving,simple,rapid,accurate and robust,widely used,which can be applied to combination medication studies of linezolid and vancomycin and their therapeutic drug monitoring in pediatric patients.

Objective: To understand the prevalence and associated factors of functional constipation(FC) among primary and middle school students in Shaanxi Province, in order to provide a basis for preventing FC in students. Methods: A stratified cluster random sampling method was used to conduct a questionnaire survey on 9 133 primary and middle school students aged 10-18 in eight primary and secondary schools in Shaanxi Province from March to September,2017. Chi square test and multivariate Logistic regression were used to analyze the associated factors of FC among primary and middle school students in Shaanxi Province. Results: There were a total of 364 students meeting the FC Rome IV diagnostic criteria, with a prevalence rate of 3.99%. Among them, there were 155 male students with a prevalence rate of 3.43%, and 209 female students with a prevalence rate of 4.53%. Univariate analysis showed that gender, breastfeeding, separation from parents, long term school meals, types of staple foods, breakfast frequency, cold foods eating frequency, spicy foods eating frequency, fried food eating frequency, pickled food eating frequency, desserts eating frequency, vegetables eating frequency were related to FC, and the differences were statistically significant ( χ 2=7.30,18.75, 20.89,35.54,22.43,16.05,21.31,13.97,10.33,23.96,16.25,17.74, P <0.05). Multivariate Logistic regression analysis showed that female, non breastfeeding, separation from parents, long term school meals, low consumption of staple food/staple food dominated by rice, and never eating vegetables were positively correlated with FC( OR =1.37,1.96,1.52,2.07,1.76,1.58,2.31, P < 0.05 ). Conclusions The prevalence of functional constipation is higher in primary and middle school students. Attention should be paid to factors related to students dietary habits and food classification to prevent the occurrence of FC in primary and middle school students.
