In modern society, sugary foods have become an integral part of many people′s lives. However, excessive sugar consumption has adverse effects on both overall health and oral health, serving as a contributing factor to the global increasing incidence in oral diseases, cardiovascular diseases, cancers, obesity, and diabetes. In response to the health risks related to high-sugar diets, the World Health Organization (WHO) and World Dental Federation (FDI) have proposed initiatives and recommendations, with various governments implementing different policies and strategies to reduce sugar intake. Chinese government has also taken proactive measures. The "Healthy China Action (2019-2030)" initiative introduced by the State Council in 2019 established a crucial benchmark in limiting the average daily intake of added sugar to 25 g per person forward to 2030. Experts from Chinese Center for Disease Control and Prevention and the field of oral health have meticulously examined the impacts of sugar reduction on oral health, as well as strategies, methods, and practical considerations related to reducing sugar intake through several meeting and wrote the "Expert consensus: reducing free-sugar for caries prevention", which was subsequently reviewed and revised based on the feedback from multiple stakeholders. They have conducted thorough analyses of global trends in sugar reduction and best practices to provide valuable insights to China for crafting effective policies and strategies on sugar reduction. This consensus mainly includes the classification of free sugars, the latest scientific evidence on dental caries, recommendations from WHO on sugar-sweetened beverage taxes, nutrition labeling, advertising, food reform, adjusting supply systems, education, and promotion strategies, as well as sugar reduction actions taken by various governments around the world. Combining the actual situation in China, policy recommendations and authoritative popular science knowledge on sugar reduction for caries prevention to public are proposed to advocate for experts in multiple fields to focus on sugar reduction for caries prevention, promote the work process, and provide the scientific basis for oral health educators.

OBJECTIVE: Evaluate the clinical application effect of low-field infant MRI. METHODS: Using literature review, expert consultation, and two rounds of Delphi to determine the evaluation index system. Then retrospectively analyze and compare the data of low-field infant MRI and high-field MRI from January 2023 to December 2024. RESULTS: There is a certain gap between low-field infant MRI and high-field MRI in terms of signal-to-noise ratio, image uniformity, software system reliability, scanning time, user interface friendliness and image result consistency. However, there was no difference in terms of spatial resolution and image quality. The noise, hardware system reliability, mean time between failure and the rate of examination completed without sedation are better than that of high-field MRI. CONCLUSION Low-field infant MRI meets needs of clinical diagnostic and has stable performance. It can be used as a routine screening tool for brain diseases near the bed.

Objective: To investigate the correlation between Notch pathway expression in nasal polyps and Treg percentage and Eos infiltration. Methods: Patients with chronic sinusitis and simple nasal septum deviation who received nasal endoscopic surgery in the Third Affiliated Hospital of Sun Yat-Sen University between November 2012 and August 2018 were selected and enrolled in CRS group and control group respectively. Nasal mucosa tissues were collected from 30 CRSsNP patients (14 males and 16 females aged from 18 to 63), 58 CRSwNP patients (38 males and 20 females aged from 18 to 65) and 29 patients (19 males and 10 females aged from 20 to 57), who underwent nasal endoscopic surgery for correction of simple nasal septum deviation. Hematoxylin-eosin(HE) staining was used to observe the infiltration of eosinophilic granulocytes in the tissues and to classify chronic sinusitis with polyps (CRSwNP) into eosinophilic chronic rhinosinusitis with nasal polyps (Eos-CRSwNP)and non-eosinophilic chronic rhinosinusitis with nasal polyps (Eos-CRSwNP). Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of Notch pathway receptors (Notch-l, 2, 3, 4) and their ligands (Jagded-l, Jagded-2, Delta-l, Delta-3and Delta-4) in the nasal mucosa of each group, as well as the expression of Th2 cytokines (IL-4, IL-5, IL-13), eosinophilic cationic protein (ECP)and the key transcription factor Foxp3 in Treg cells. Finally, flow cytometry was used to detect CD4⁺CD25⁺Foxp3⁺ Treg cells in nasal mucosa of each group. Results: Compared with controls, the expression of Th2 cytokines (IL-4, IL-5, IL-13) in CRSsNP and non-Eos-CRSwNP patients was the highest in Eos-CRSwNP (F=16.930,9.197,9.116, all P<0.05). Foxp3 had the lowest expression in Eos-CRSwNP patients and was lower than non-Eos-CRSwNP patients (F=2.780,P<0.05), and was negatively correlated with ECP (r=-0.326,P<0.05). Compared with controls, Eos-CRSwNP patients in CRSsNP patients and non-Eos-CRSwNP patients exhibited a significantly lower frequency of CD4⁺CD25⁺Foxp3⁺Treg cells (F=13.140, all P<0.01). The expression of Notch-l and Jagged-l in Eos-CRSwNP was significantly higher than that of the controls, CRSsNP patients and non-Eos-CRSwNP patients (F=5.953/F=6.380, P<0.05). In the nasal polyp group, the expression of Notch-l and Jagged-l showed significantly negative correlation with Foxp3 (r=-0.611/-0.346, all P<0.05), and positive correlation with Th2 cytokines (IL-4, IL-5, IL-13) and ECP, respectively (r=0.781/0.459,0.621/0.601,0.605/0.490,0.464/0.668, all P<0.05). There was no significant difference in the expression of receptor and ligand of the other Notch pathway among the groups. Conclusion: Abnormal activation of Notch-l/Jagged-l pathway may be involved in decreasing Treg ratio in Eos-CRSwNP, thereby promoting Th2 inflammatory response and Eosinophil infiltration.

Background::Accurate prediction of ischemic stroke is required for deciding anticoagulation use in patients with atrial fibrillation (AF). Even though only 6% to 8% of AF patients die from stroke, about 90% are indicated for anticoagulants according to the current AF management guidelines. Therefore, we aimed to develop an accurate and easy-to-use new risk model for 1-year thromboembolic events (TEs) in Chinese AF patients.Methods::From the prospective China Atrial Fibrillation Registry cohort study, we identified 6601 AF patients who were not treated with anticoagulation or ablation at baseline. We selected the most important variables by the extreme gradient boosting (XGBoost) algorithm and developed a simplified risk model for predicting 1-year TEs. The novel risk score was internally validated using bootstrapping with 1000 replicates and compared with the CHA 2DS 2-VA score (excluding female sex from the CHA 2DS 2-VASc score). Results::Up to the follow-up of 1 year, 163 TEs (ischemic stroke or systemic embolism) occurred. Using the XGBoost algorithm, we selected the three most important variables (congestive heart failure or left ventricular dysfunction, age, and prior stroke, abbreviated as CAS model) to predict 1-year TE risk. We trained a multivariate Cox regression model and assigned point scores proportional to model coefficients. The CAS scheme classified 30.8% (2033/6601) of the patients as low risk for TE (CAS score = 0), with a corresponding 1-year TE risk of 0.81% (95% confidence interval [CI]: 0.41%-1.19%). In our cohort, the C-statistic of CAS model was 0.69 (95% CI: 0.65-0.73), higher than that of CHA 2DS 2-VA score (0.66, 95% CI: 0.62-0.70, Z = 2.01, P = 0.045). The overall net reclassification improvement from CHA 2DS 2-VA categories (low = 0/high ≥1) to CAS categories (low = 0/high ≥1) was 12.2% (95% CI: 8.7%-15.7%). Conclusion::In Chinese AF patients, a novel and simple CAS risk model better predicted 1-year TEs than the widely-used CHA 2DS 2- VA risk score and identified a large proportion of patients with low risk of TEs, which could potentially improve anticoagulation decision-making.

Lilii Bulbus, which comes from many medicinal plants，is a frequently-used traditional Chinese medicine，the records in previous herbal literatures of it's origin and quality were inconstant. To trace back it's sources, we conducted a systematical study on it's origin and quality by textual research and investigation in this paper,The result showed that the origins of Lilii Bulbus are mainly source from white-flowers, red-yellow-flowers and red-flowers of Lilium， L. brownii var. viridulum, which were believed authentic or good quality in all previous herbal literatures,and L. pumilum and L. concolor which belong to white-flowers,and L. lancifolium which belong to red-yellow-flowers were believed low-quality and unfit for medicinal uses, or they were listed below and often have different effect with L. brownii var. viridulum. Among them, only L. concolor does not belong to Lilii Bulbus according to Chinese Pharmacopeia (2015 edition), The mainstream varieties of Lilii Bulbus became L. lancifolium now according to our practical investigation, which were very different from previous herbal literatures. Although chemical and pharmacological studies provided a reference for L. lancifolium，we should respect the actual records of the previous herbal literatures，the research of material foundation of efficacy should be more sufficient，and provide science evidence for clinical application of different species of Lilii Bulbus.

OBJECTIVE: To investigate the efficacy of domestic decitabine (D) combined with pre-excitation chemotherapy consisted of Ara-c, THP and G-CSF(CTG) in treatment of middle-aged and elderly patients with MDS-transformed AML and prognosis-related factors. METHODS: Seventy-six patients with MDS-transformed AML treated in our hospital from June 2013 to June 2015 were selected according to treatment regimens, 76 patients were divided into 2 groups: CTG group(36 cases) and D+CTG group(40 cases). The patients in CTG group received treatment with Ara-C, THP and G-CSF; the patients received the treatment with decitabine plus CTG. The patients in 2 groups all received 4 course treatment, then received maintaining treatment. The therapeutic efficacy and incidence of adverse reactions in 2 group were compared, at the same time, the risk factors affecting the prognos of patients treated with D+CTG were analyzed. RESULTS: There were no siginificant differences in age, sex, initial blood cell count, bone marrow blast ratio, disease types, chromosome karyotypes and FLT3-ITD gene mutation between 2 groups. The efficacy analysis showed that the efficacy of D+CTG was superior to CTG, ORR in D+CTG group was significantly higher than that in CTG group (72、52 vs 50%) (P<0.05), moreover, no significant differences in bone marrow inhibition digree infeetion, gastroinfestinal response and liver damage were found between 2 groups (P>0.05). The follow-np for 2 years showed that the median survival time in D+CTG group was significantly longer than that in CTG group (19.9 vs 11.0 months) (P<0.05). The multivariate analysis showed that the 1 course efficacy (RR=3.926, P=0.015) and FLT3-ITD gene mutation (RR=4.347, P=0.004) were independent risk factors affecting the efficacy of D+CTG treatment. CONCLUSION The short-and long-term efficacy of domestic decitasine combined with preexcitation chenotherapy in treatment of middec-aged and eldery patients with MDS transformed AML is superior to single pre-excitation chenothrapy, moreover the incidence of adverse reactions did not increase. The 1 course efficacy and FLT-3 ITD gene mutation are the independent risk factors affecting the prognosis of patients. .
