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 screen the distribution frequency of Mur blood group among voluntary blood donors in Hezhou,Guangxi,and further analyze the molecular basis of of Mur antigen positive samples.Methods The Mur pheno-type of voluntary blood donors in Hezhou was serologically screened using microplate method,and the distribution frequency of Mur antigens in different ethnic groups was analyzed.Genetic typing was performed on these positive samples with PCR-SSP method to verify the accuracy of the serological method,and the genetic background was sequenced and analyzed.Re-sults Among 3 298 samples from voluntary blood donors in Hezhou,432(13.10%,432/3 298)were screened positive for Mur antigen,and PCR-SSP genotyping validation showed that all 432 samples were electrophoretic positive.Among them,the proportion of Han blood donors with positive Mur antigen was12.79%(331/2 587),Yao ethnic group was13.25%(64/483),Zhuang ethnic group was 16.51%(36/218),and no statistically significant difference was found in the three groups(P＞0.05).Further sequencing results showed that 428 samples were GYP(B-A-B)Mur,also known as GYP.Mur type(12.98%,428/3 298),the other 4 samples were GYP(B-A-B)Bun,also known as GYP.Bun type(0.12%,4/3 298).Conclusion The Mur blood type frequency is high in the voluntary blood donors in Hezhou,Guangxi,and is predominant characterized by GYP.Mur genotype.Due to ethnic integration,no significant difference was noticed in the frequency of Mur blood type distribution between Han,Zhuang and Yao population.Therefore,conducting extensive Mur blood group antigen and antibody testing in Hezhou is of great significance for ensuring clinical blood transfusion safety.

OBJECTIVE To explore the neuroprotective effect and possible mechanism of celastrol （Cel） and its derivatives （Cel-1， Cel-2） in terms of neuroinflammation and oxidative damage. METHODS Neuroinflammation model of microglial BV2 cells was induced by 1 μg/mL lipopolysaccharide （LPS）； oxidative damage model of human neuroblastoma SH-SY5Y cells was induced by 200 μmol/L hydrogen peroxide （H2O2）. The toxicity of different concentrations of Cel， Cel-1 and Cel-2 （0.625-20 μmol/L） to the two types of cells was investigated. The levels of nitric oxide （NO）， tumor necrosis factor α （TNF-α）， interleukin 1β （IL-1β）， and IL-6 in BV2 cells induced by LPS at safe concentrations （0.039-0.625 μmol/L） were all detected. The survival rate of SH-SY5Y cells induced by H2O2 was also determined. The expression levels of phosphoinositide 3-kinase （PI3K）， p-PI3K， protein kinase B （Akt）， p-Akt， cystatinase 3 （caspase-3）， B-cell lymphoma 2 （Bcl-2） and Bcl-2-related X protein （Bax） in SH- SY5Y cells induced by H2O2 at 0.156， 0.313， 0.625 μmol/L of active compound 2 were all detected. RESULTS In the concentration gradient range between 0.039 and 0.625 μmol/L， the results of neuroinflammation model experiments showed that Cel， Cel-1 and Cel-2 could reduce the contents of NO， TNF-α， IL-1β， and IL-6 in culture medium of BV2 cells （P＜0.05 or P＜ 0.01）； their IC50 values for neuroinflammation were （0.25±0.04）， （0.61±0.14） and （0.11±0.02） μmol/L respectively. Meanwhile， all of them could reverse the phenomenon of decreased cell survival rate after H2O2 treatment in the oxidative damage experiments at a certain concentration （P＜ 0.05 or P＜0.01）， with neuroprotective EC50 values of （0.43± XJC2023009） 0.08）， （0.45±0.04） and （0.28±0.03） μmol/L， respectively.Induced by H2O2， the phosphorylation of PI3K and Akt protein， protein expressions of Bcl-2 and Bcl-2/Bax ratio were all increased significantly （P＜0.05 or P＜0.01）， while the protein expressions of caspase-3 and Bax were decreased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS Cel， Cel-1， and Cel-2 all have significant neuroprotective activities at certain concentrations， and Cel-2 shows the most significant protective effect. The mechanism of action of Cel-2 may be related to regulating the PI3K/Akt and caspase-3/Bcl-2/Bax signaling pathways， reducing the inflammatory response， oxidative stress damage and inhibiting neuronal apoptosis.

Odontogenic maxillary sinusitis(OMS)is a subtype of maxillary sinusitis(MS).It is actually inflammation of the maxillary sinus that secondary to adjacent infectious maxillary dental lesion.Due to the lack of unique clinical features,OMS is difficult to distinguish from other types of rhinosinusitis.Besides,the characteristic infectious pathogeny of OMS makes it is resistant to conventional therapies of rhinosinusitis.Its current diagnosis and treatment are thus facing great difficulties.The multi-disciplinary cooperation between otolaryngologists and dentists is absolutely urgent to settle these questions and to acquire standardized diagnostic and treatment regimen for OMS.However,this disease has actually received little attention and has been underrepresented by relatively low publication volume and quality.Based on systematically reviewed literature and practical experiences of expert members,our consensus focuses on characteristics,symptoms,classification and diagnosis of OMS,and further put forward multi-disciplinary treatment decisions for OMS,as well as the common treatment complications and relative managements.This consensus aims to increase attention to OMS,and optimize the clinical diagnosis and decision-making of OMS,which finally provides evidence-based options for OMS clinical management.

Objective:To analyze the changes in cardiac structure and function in women with different types of hypertensive disorders in pregnancy (HDP) and explore their influencing factors.Methods:A total of 1 967 pregnant women diagnosed with HDP who delivered at Peking University Third Hospital from January 1, 2014 to April 15, 2022 were included in the study. They were categorized into four groups based on specific HDP diagnoses: gestational hypertension (506 cases, 25.7%), pre-eclampsia (589 cases, 29.9%), pregnancy complicated with chronic hypertension (332 cases, 16.9%) and chronic hypertension with pre-eclampsia (540 cases, 27.5%). Differences in cardiac structure and function among four groups were retrospectively analyzed. Cardiac structure indicators included left atrial diameter (LAD), left atrial area (LAA), right atrial area (RAA), left ventricular end-diastolic diameter (LVEDD), interventricular septal thickness (IVST), left ventricular posterior wall thickness (LVPWT), systolic function indicators included left ventricular ejection fraction (LVEF), lateral systolic mitral annular velocity (Sm), diastolic function indicators included peak early diastolic mitral in flow velocity (E)/peak late diastolic mitral in flow velocity (A), and E/peak early diastolic myocardial velocity of the lateral mitral annulus early diastolic velocity (Em). Influencing factors on cardiac structure and function were analyzed using generalized linear regression. Influencing factors were assessed by generalized linear regression.Results:(1) General clinical data: the differences in age, gestational week at delivery, blood pressure, proportion of diabetes, and length of hospital stay were statistically significant among four different HDP types (all P<0.05). (2) Compared with pregnant women with pregnancy complicated with chronic hypertension, pre-eclampsia, and gestational hypertension, those with chronic hypertension with pre-eclampsia had larger LAD, LAA, RAA and LVEDD (all P<0.001), thicker IVST and LVPWT (all P<0.001), and reduced left ventricular diastolic function (E/A, lateral Em, E/Em) and systolic function (lateral Sm; all P<0.001). Pregnant women with gestational hypertension had the least changes in cardiac structure and function. Compared with pregnant women with pre-eclampsia, those with pregnancy complicated with chronic hypertension had smaller RAA ( P<0.001) and lower E/A ( P<0.001), with no significant difference in other indicators (all P>0.05). (3) Chronic hypertension with pre-eclampsia, pregnancy complicated with chronic hypertension, and pre-eclampsia were associated with larger LAD, LAA, and LVEDD, and lower lateral Em (all P<0.05). Conclusions:Different types of HDP are associated with distinct changes in cardiac structure and function. Chronic hypertension with pre-eclampsia demonstrates the most pronounced alterations, followed by pre-eclampsia and pregnancy complicated with chronic hypertension, and gestational hypertension showed the least changes.

BACKGROUND: Endocrine therapy (ET) and ET-based regimens are the preferred first-line treatment options for hormone receptor (HR)-positive and human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer (HR+/HER2- MBC), while chemotherapy (CT) is commonly used in clinical practice. The aim of this study was to investigate the efficacy and clinical outcome of ET and CT as first-line treatment in Chinese patients with HR+/HER2- MBC. METHODS: Patients diagnosed with HR+/HER2-MBC between January 1st, 1996 and September 30th, 2018 were screened from the Chinese Society of Clinical Oncology Breast Cancer database. The initial and maintenance first-line treatment, progression-free survival (PFS), and overall survival (OS) were analyzed. RESULTS: Among the 1877 included patients, 1215 (64.7%) received CT and 662 (35.3%) received ET as initial first-line treatment. There were no statistically significant differences in PFS and OS between patients receiving ET and CT as initial first-line treatment in the total population (PFS: 12.0 vs. 11.0 months, P = 0.22; OS: 54.0 vs . 49.0 months, P =0.09) and propensity score matched population. For patients without disease progression after at least 3 months of initial therapy, maintenance ET following initial CT (CT-ET cohort, n = 449) and continuous schedule of ET (ET cohort, n = 527) had longer PFS than continuous schedule of CT (CT cohort, n = 406) in the total population (CT-ET cohort vs. CT cohort: 17.0 vs . 8.5 months; P <0.01; ET cohort vs . CT cohort: 14.0 vs . 8.5 months; P <0.01) and propensity score matched population. OS in the three cohorts yielded the same results as PFS. CONCLUSIONS ET was associated with similar clinical outcome to CT as initial first-line treatment. For patients without disease progression after initial CT, switching to maintenance ET showed superiority in clinical outcome over continuous schedule of CT.

Objective:To investigate the efficacy and safety of sivelestat sodium in patients with sepsis.Methods:The clinical data of 141 adult patients with sepsis admitted to the intensive care unit (ICU) of the First Affiliated Hospital of Zhengzhou University from January 1, 2019 to January 1, 2022 were retrospectively analyzed. The patients were divided into the sivelestat sodium group ( n = 70) and the control group ( n = 71) according to whether they received sivelestat sodium or not. The efficacy indexes included oxygenation index, procalcitonin (PCT), C-reactive protein (CRP), white blood count (WBC), sequential organ failure assessment (SOFA), acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) before and after 7 days of treatment, as well as ventilator supporting time, the length of ICU stay, the length of hospital stay and ICU mortality. The safety indicators included platelet count (PLT) and liver and kidney function. Results:There were no significant differences in age, gender, underlying diseases, infection site, basic drugs, etiology, oxygenation index, biochemical indexes, SOFA and APACHE Ⅱ scores between the two groups. Compared with the control group, the oxygenation index in 7 days was significantly increased [mmHg (1 mmHg ≈ 0.133 kPa): 233.5 (181.0, 278.0) vs. 202.0 (153.0, 243.0), P < 0.01], the levels of PCT, CRP, alanine aminotransferase (ALT) and APACHE Ⅱ score were significantly decreased in the sivelestat sodium group [PCT (μg/L): 0.87 (0.41, 1.61) vs. 1.53 (0.56, 5.33), CRP (mg/L): 64.12 (19.61, 150.86) vs. 107.20 (50.30, 173.00), ALT (U/L): 25.0 (15.0, 43.0) vs. 31.0 (20.0, 65.0), APACHE Ⅱ: 14 (11, 18) vs. 16 (13, 21), all P < 0.05]. However, there were no significant differences in SOFA, WBC, serum creatinine (SCr), PLT, total bilirubin (TBil), aspartate aminotransferase (AST) in 7 days between the sivelestat sodium group and the control group [SOFA: 6.5 (5.0, 10.0) vs. 7.0 (5.0, 10.0), WBC (×10 9/L): 10.5 (8.2, 14.7) vs. 10.5 (7.2, 15.2), SCr (μmol/L): 76.0 (50.0, 124.1) vs. 84.0 (59.0, 129.0), PLT (×10 9/L): 127.5 (59.8, 212.3) vs. 121.0 (55.0, 211.0), TBil (μmol/L): 16.8 (10.0, 32.1) vs. 16.6 (8.4, 26.9), AST (U/L): 31.5 (22.0, 62.3) vs. 37.0 (24.0, 63.0), all P > 0.05]. The ventilator supporting time and the length of ICU stay in the sivelestat sodium group were significantly shorter than those in control group [ventilator supporting time (hours): 147.50 (86.83, 220.00) vs. 182.00 (100.00, 360.00), the length of ICU stay (days): 12.5 (9.0, 18.3) vs. 16.0 (11.0, 23.0), both P < 0.05]. However, there were no significant differences in the length of hospital stay and ICU mortality between the sivelestat sodium group and the control group [the length of hospital stay (days): 20.0 (11.0, 27.3) vs. 13.0 (11.0, 21.0), ICU mortality: 17.1% (12/70) vs. 14.1% (10/71), both P > 0.05]. Conclusions:Sivelestat sodium is safe and effective in patients with sepsis. It can improve the oxygenation index and APACHE Ⅱ score, reduce the levels of PCT and CRP, shorten ventilator supporting time and the length of ICU stay. No adverse reactions such as liver and kidney function injury and platelet abnormality are observed.

OBJECTIVE: To explore the effect of Xuebijing injection on inflammation in sepsis by regulating intestinal microbiota and its metabolites. METHODS: A total of 45 male Sprague-Dawley (SD) rats were randomly divided into Sham operation group (Sham group), cecal ligation and perforation (CLP) induced sepsis group (CLP group), and Xuebijing intervention group (XBJ group, 4 mL/kg Xuebijing injection was injected intraperitoneally at 1 hour after CLP), with 15 rats in each group. The survival of rats was observed at 24 hours after operation and sacrificed. Feces were collected for 16S rRNA gene sequencing and liquid chromatography-mass spectrometry (LC-MS) analysis. RESULTS: At 24 hours after operation, all rats in the Sham group survived, the mortality of rats in the XBJ group was lower than that in the CLP group [47% (7/15) vs. 60% (9/15), P > 0.05]. Compared with the Sham group, the diversity of gut microbiota in the CLP group decreased, the dominant flora changed, and the abundance of inflammation-related flora increased. Xuebijing improved the changes in gut microbiota caused by sepsis, and α diversity showed an increasing trend (Ace index: 406.0±22.5 vs. 363.2±38.2, Chao1 index: 409.7±21.8 vs. 362.4±42.5, both P > 0.05). Restrictive constrained principal coordinate analysis (cPCoA) showed a high similarity in gut microbiota among the same group of rats. The CLP group was dominated by Bacteroidetes, while the Sham and XBJ groups were dominated by Firmicutes. In addition, compared with the CLP group, Xuebijing treatment increased the abundance of beneficial bacteria in septic rats, such as Verrucomicrobia, Akkermansia and Lactobacillus. LC-MS and orthogonal partial least squares discriminant analysis (OPLS-DA) showed that there were 12 main differential metabolites among the three groups, and there were certain correlations between these metabolites, which were related to amino acid and lipid metabolism. Correlation analysis showed a significant correlation between changes in metabolites and microbial communities. CONCLUSIONS Xuebijing can improve the survival rate of septic rats, regulate the composition of intestinal flora and related metabolites, which provides a new pathophysiological mechanism for Xuebijing in the treatment of sepsis.

Objective:To construct a social loss indicator system based on the perspective of epidemic prevention and control against background of emerging major infectious diseases at the national, hospital, and individual levels, and to provide decision-making basis for public general hospitals to formulate prevention and control strategies for emerging major infectious diseases.Methods:Literatures published before December 23, 2020 were retrieved from CNKI, Wanfang, VIP, Web of Science, Google Scholar with such keywords as " infectious diseases" " public health emergencies" " social losses" " COVID-19" " evaluation". Then a preliminary social loss indicator system of public general hospitals for emerging major infectious diseases was constructed from such dimensions as country, hospital, and individual, by implementing literature analysis and expert consultation. Based on such a preliminary system, three questionnaires were designed for the country, hospitals, and individuals and the corresponding data were collected from December 25, 2021 to May 20, 2022. In the end, a factor analysis was made on the questionnaire data to optimize the social loss indicator system and determine the weights of each indicator.Results:The social loss indicator system consists of 14 level-1 indicators and 60 level-2 indicators. Level-1 indicators at country aspect consisted of government governance capacity, direct economic losses, social security, online public opinion, indirect economic losses, and international cooperation; indicators at hospital aspect consisted of hospital manpower, material resources, and information resources, hospital services, and hospital operations; indicators at the individual aspect consisted of physical health, psychological and social health, and external environment. Level-1 indicators of the highest weight at all aspects were social security, manpower, material and information resources, as well as physiological health. And the level-2 indicators of the highest weight were high medical expenses, overwork for staff other than doctors and nurses and medical insurance.Conclusions:The social loss indicator system for emerging major infectious diseases constructed in this study proves scientific and reasonable, helpful for the formulation of prevention and control strategies of public general hospitals.
