This study is designed to investigate the bioactive components on increasing peak bone mass (PBM) by exploring the spectrum-effect relationship between chromatography fingerprints and effect. Multiple indicators are selected to evaluate the pharmacological activity. In fingerprints, 21 common peaks are obtained, five of which are identified. Furthermore, gray relational analysis (GRA) is a quantitative method of gray system theory and is used to describe the correlation degree of common peaks and pharmacological activities with relational value. 21 components are then divided into three different regions, of which ononin and calycosin play an extremely significant role in increasing PBM. In addition, factor analysis and hierarchical cluster analysis (HCA) are used to screen the optimal producing area for Radix Hedysari. This provides a comprehensive and efficient method to improve the quality evaluation of Radix Hedysari, confirming the bioactive components for PBM-enhancement and further develop its medicinal value.展开更多
目的比较不同部位骨密度测定对老年男性2型糖尿病患者骨量变化的诊断价值,并探讨影响糖尿病患者骨密度值的相关因素。方法骨量正常的门诊老年男性2型糖尿病患者97例,按年龄分成三组,其中60～69岁组共25例,70～79岁组共37例,80岁以上组...目的比较不同部位骨密度测定对老年男性2型糖尿病患者骨量变化的诊断价值,并探讨影响糖尿病患者骨密度值的相关因素。方法骨量正常的门诊老年男性2型糖尿病患者97例,按年龄分成三组,其中60～69岁组共25例,70～79岁组共37例,80岁以上组共35例。比较三组间左侧股骨颈、右侧股骨颈、L1、L2、L3、L4部位的骨密度(Bone mineral density,BMD)及T值差异,找出反映不同年龄组间骨量变化的敏感部位。探讨老年男性2型糖尿病患者的年龄、病程、体重指数(Body mass index,BMI)、合并用药、血钙(Calcium,Ca)、血磷(Phosphorus,P)、碱性磷酸酶(Alkaline phosphatase,ALP)、空腹血糖(Fasting plasma glucose,FPG)、餐后血糖(Postprandial blood glucose,PPG)、糖化血红蛋白(Hemoglobin A1c,HbA1c)、血压(Blood pressure,BP)、甘油三酯(Triglyceride,Tg)、总胆固醇(Total cholesterol,Tc)、高密度脂蛋白胆固醇(High density lipoprotein cholesterol,HDL-C)、低密度脂蛋白胆固醇(Low density lipoprotein cholesterol,LDL-C)与骨密度值的相关性。使用相关及回归分析判断影响骨密度变化的独立危险因素。结果 1、左侧股骨颈测定的骨密度值及T值在不同年龄组间及每两组之间差异均存在统计学意义(P<0.05),随年龄增加骨密度值及T值逐渐降低。2、相关分析显示,老年男性2型糖尿病患者的左侧股骨颈骨密度与年龄、糖尿病病程、FPG、PPG、HbA1c、P、ALP、应用噻唑烷二酮类(Thiazolidinediones,TZDs)呈负相关,与BMI呈正相关。回归分析可见,年龄、病程、BMI、HbA1c、使用噻唑烷二酮类是影响老年男性2型糖尿病患者骨密度的独立危险因素。结论对老年男性2型糖尿病患者,左侧股骨颈部位的骨密度测定能较好的反映骨量随年龄的丢失程度。高龄、低体重、较长的糖尿病病程、较高的HbA1c、使用噻唑烷二酮类药物等可能会增加老年男性2型糖尿病患者的骨量丢失。展开更多
目的分析婴儿期钙营养状况的有关影响因素,为早期防治和改善婴儿钙营养状况提供科学依据。方法随机抽取武汉地区0～1岁婴儿,采用双能X线吸收法(DEXA)检测其骨密度(bone mineral density,BMD),将BMD值正常者列入对照组,BMD值异常者列入...目的分析婴儿期钙营养状况的有关影响因素,为早期防治和改善婴儿钙营养状况提供科学依据。方法随机抽取武汉地区0～1岁婴儿,采用双能X线吸收法(DEXA)检测其骨密度(bone mineral density,BMD),将BMD值正常者列入对照组,BMD值异常者列入病例组,采用1:1配对病例对照研究,共计133对。采用统一自制的调查表进行问卷调查,对婴儿BMD的有关影响因素进行回归分析。结果经多因素条件Logistic回归分析,婴儿BMD的主要不良影响因素依次为早产适于胎龄儿、出生窒息、低出生体重、食欲不佳和呼吸道感染,OR值分别为0.465、0.301、0.598、0.560和0.616。添加动物食物量、户外活动时间和补钙剂量为BMD的有利因素,OR值分别为0.526、0.435和0.998。结论婴儿期BMD受到来自孕期、围产期、营养和疾病等多种因素的影响,应降低围产期高危因素,婴儿期要及时调整膳食结构,加强户外活动,适当补充钙剂和鱼肝油,改善婴儿钙营养状况。展开更多
