Enhanced fluoride uptake from mouthrinses

It has been shown in laboratory and animal studies that tooth enamel becomes considerably more reactive toward low levels of fluoride after receiving pre-treatment which forms dicalcium phosphate dihydrate (DCPD) in the enamel as an intermediate. This in vitro study was undertaken to determine the effect on human enamel fluoride uptake of incorporating DCPD-forming rinses into a conventional fluoride rinsing program. In one group, enamel samples received a one-minute rinse with 0.2% NaF each day for 20 days. Samples in the second group were treated identically, except that they were also given a one-minute DCPD-forming rinse prior to the first, sixth, eleventh, and sixteenth fluoride rinses. At the end of the rinsing program, all samples were washed in 1 M KOH to remove labile fluorides. The enamel biopsy data showed that the fluoride uptake resulting from 0.2% NaF alone was not statistically significant, whereas uptake produced by the DCPD-forming plus NaF rinses was significant. The results suggest that the DCPD-forming rinse may improve the efficacy of fluoride rinse programs.     

肺肿瘤性磨玻璃结节平均CT值测量相关技术的影响因素研究

目的 分析CT扫描剂量、重建算法、层面选择及胸部不同位置对纯磨玻璃肺结节(pGGN)平均CT值测量偏差度的影响,评价影响肺肿瘤性磨玻璃结节(GGN)平均CT值测量的因素.方法 选用CT值为-650 HU的不同直径球形模拟肺pGGN,应用东芝(佳能)64排螺旋CT,设置4种剂量等级自动管电流调制技术扫描,3种三维权重自适应迭代重建剂量降低(AIDR-3D)算法重建,测量1 mm薄层图像肺结节平均CT值,计算偏差度.结果 低剂量模式扫描时,小于10 mm的球形pGGN平均CT值的偏差度较大.3种AIDR算法重建下,相同直径球形pGGN平均CT值偏差度差异较小;pGGN直径越小,球形pGGN平均CT值偏差度越大.在球形pGGN中心层面测量CT值,平均CT值的偏差度最小;偏离中心层面越远,偏差度越大.胸部3个位置的pGGN平均CT值偏差度均不同,肺实质内平均CT值偏差度最小.结论 除重建算法,CT扫描剂量、测量层面选择及结节所在胸部位置对于pGGN平均CT值测量的精准度均可造成影响.     

盆底超声参数与SUI患者肌纤维疲劳度和病情程度的相关性分析

目的 探讨盆底超声参数与压力性尿失禁(SUI)患者病情程度、肌纤维疲劳度的相关性.方法 选取2018年10月至2020年3月该院SUI患者146例为研究对象,均接受盆底超声检查并给予盆底肌训练.分析盆底超声参数[膀胱颈旋转角度(θ)、膀胱颈下移距离(X)、膀胱颈移动度(Mu)、膀胱尿道后角(α)]与SUI问卷评分(SS)、肌纤维疲劳度的相关性,以及分析其预测SUI疗效不佳的价值.结果 不同病情程度患者年龄、受教育程度、年收入、分娩方式、会阴情况、流产次数和X比较差异无统计学意义(P>0.05),BMI、既往分娩次数、新生儿体重、θ、Mu、α比较差异有统计学意义(P<0.05).SUI患者X与SS、盆底肌纤维疲劳度无显著相关性(P>0.05),θ、Mu、α与SS评分、盆底肌纤维疲劳度呈正相关(P<0.05).疗效良好者θ、Mu、α低于疗效不佳者(P<0.05);θ预测的曲线下面积(AUC)最大,临界值37.35°时,其灵敏度、特异度分别为94.74％、59.84％.结论 盆底超声参数中θ、Mu、α与SUI患者肌纤维疲劳度、病情程度存在良好线性关系.     

Inverted U-Shaped Associations between Glycemic Indices and Serum Uric Acid Levels in the General Chinese Population: Findings from the China Cardiometabolic Disease and Cancer Cohort (4C) Study

Objective The relationship between serum uric acid(SUA)levels and glycemic indices,including plasma glucose(FPG),2-hour postload glucose(2 h-PG),and glycated hemoglobin(HbA1 c),remains inconclusive.We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.Methods The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study.A total of 105,922 community-dwelling adults aged≥40 years underwent the oral glucose tolerance test and uric acid assessment.The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.Results A total of 30,941 men and 62,361 women were eligible for the current analysis.Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels,but with different inflection points in men and women.The thresholds for FPG,2 h-PG,and HbA1 c for men and women were 6.5/8.0 mmol/L,11.0/14.0 mmol/L,and 6.1/6.5,respectively(SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes,while the inflection points were reached earlier in men than in women.     

National Nutrition and Health Systematic Survey for Children 0-17 Years of Age in China

The main purpose of the National Nutrition and Health Systematic Survey for children 0-17 years of age in China (CNHSC) was to collect basic data on the nutrition, development, and health status for children in different regions across China using evidence-based, reliable, and cost-effective approaches. Children and their parents or guardians from seven regions (south, southwest, north, northwest, eastern, central, and northeast China) in China were recruited. A multi-stage stratified randomized sampling method was used. Two provinces were randomly sampled from each of the seven regions, from which one urban district and one rural country were also randomly sampled, resulting in a total of 28 survey counties/districts. Dietary surveys, health examinations, laboratory testing, and questionnaires were used to collect dietary intake, nutritional status, child development, and health status information. Nutrition, health, and lifestyle assessment of children and their parents was determined using the Knowledge Attitude Practice (KAP) survey. Greater than 100,000 children (38,000 children < 6 years of age and 66,000 children 6-17 years of age) completed the survey. The survey provided comprehensive data on child nutrition and health status for future studies and will serve as the basis for an integrated nutrition and health improvement strategies proposal for children in China.     

老年患者出院计划评估工具的研究进展

老年患者出院后再入院率高,而通过细致评估后制定出院计划是患者出院后获得高质量延续性护理的重要保证。既往已有研究者对国外出院计划评估工具的使用进行了综述,但缺乏专门针对老年患者的出院计划评估工具的相关报道。由于老年患者具有特殊性,本文主要从老年患者出院风险筛查和综合性评估的角度对国内外使用的老年患者出院计划评估工具进行综述,从而为相关医务人员选择合适的出院计划评估工具提供依据。
