Circulating adipocytokines in non-diabetic and Type 1 diabetic children: relationship to insulin therapy, glycaemic control and pubertal development.

AIM: To determine the influence of Type 1 diabetes mellitus on circulating adipocytokines in children. METHODS: The circulating concentrations of leptin, adiponectin, resistin and tumour necrosis factor (TNF)-alpha were measured in 91 children, aged 11.1 +/- 2.7 years, with Type 1 diabetes mellitus (T1DM). Ninety-one healthy children were selected as control subjects. RESULTS: Body mass index-adjusted leptin concentrations were higher in the pubertal diabetic children compared with the control children. There was a significant positive correlation between leptin and daily insulin dose in the diabetic group. Circulating adiponectin concentrations were higher in the prepubertal diabetic children and were positively associated with HbA(1c). Resistin concentrations were lower in the prepubertal non-diabetic subjects compared with the pubertal non-diabetic children, whose values were higher than those of the diabetic children. TNF-alpha concentrations were similar in non-diabetic and diabetic children. CONCLUSIONS: Circulating concentrations of adipocytokines are abnormal in Type 1 diabetic children, although the direction of change differs by cytokine. Pubertal development, in addition to insulin treatment and glycaemic control, also influences the concentrations.

小学生个性影响因素研究

【目的】分析影响儿童个性的有关因素，为培养儿童的健全人格提供依据。【方法】对西安市所属的七个区各随机抽取一所学校，每所学校抽取四、五、六年级各两个班．采用龚耀先修订的艾森克个性问卷（Eysenck Personality Questionnaire，EPQ）（儿童用）和自编的个人一般情况调查表，对2000名儿童进行调查。将调查所得数椐进行多元逐步回归分析。【结果】影响小学生个性精神性（Psy choticism，P）的因素有性别、是否班干部、父母关系；影响内外向（extrovision and intrnision，E）的因素有性别、父母关系、是否班干部、住所、母亲文化程度、所在学校；影响情绪稳定性（nearoticism，N）、掩饰性（lie,L）的均为性别、父母关系2个因素。【结论】儿童个性受家庭、学校环境等的多重影响。家长、教师应创造良好的家庭、社会环境，保持情绪乐观、稳定，避免对子女儿童的负面影响，以利于其个性向积极方向发展。     

Predictors of oral health quality of life in older adults

There is limited information regarding oral health status and other predictors of oral health‐related quality of life. An association between oral health status and perceived oral health‐related quality of life (OHQOL) might help clinicians motivate patients to prevent oral diseases and improve the outcome of some dental public health programs. This study evaluated the relationship between older persons' OHQOL and their functional dentition, caries, periodontal status, chronic diseases, and some demographic characteristics. A group of 733 low‐income elders (mean age 72.7 ISD=4.71, 55.6% women, 55.1% members of ethnic minority groups in the U.S. and Canada) enrolled in the TEETH clinical trial were interviewed and examined as part of their fifth annual visit for the trial. OHQOL was measured by the Geriatric Oral Health Assessment Index (GOHAI); oral health and occlusal status by clinical exams and the Eichner Index; and demographics via interviews. Elders who completed the four‐year assessment had an average of 21.5 teeth (SD=6.9). with 8.5 occluding pairs (SD=4.6), and 32% with occlusal contacts in all four occluding zones. Stepwise multiple regressions were conducted to predict total GOHAI and its subscores (Physical, Social, and Worry). Functional dentition was a less significant predictor than ethnicity and being foreign‐bom. These variables, together with gender, years since immigrating, number of carious roots, and periodontal status, could predict 32% of the variance in total GOHAI, 24% in Physical, 27% in Social, and 21 % in the Worry subscales. These findings suggest that functional dentition and caries influence older adults' OHQOL, but that ethnicity and immigrant status play a larger role.     

Goldenhar 综合征家系的临床表型和遗传学分析

目的分析1组Goldenhar综合征家系的临床表现及遗传学特征。方法我们随访到1组4代33人的Goldenhar综合征家系，对目前存活的29人进行了临床表型和遗传学的初步分析。结果家系内有Goldenhaar综合征患者5人．临床表现具高度多样性，累及眼、耳、脊柱、颜面、口腔等多个器官和系统的发育不良，在遗传方式上属于常染色体显性遗传。从细胞遗传学水平对家系中成员进行染色体检查，未发现核型异常。结论该Goldenhar综合征家系属常染色体显性遗传，染色体检查未发现核型异常。

保元排毒丸对顺铂引起的LLC-PK1细胞凋亡干预作用研究

目的：观察保元排毒丸对顺铂（DDP）所致猪肾小管上皮细胞（LLCPK1）凋亡的影响。方法：LLC-PK1细胞分三组培养，空白血清组采用不舍药血清进行培养，模型组分别以10和6μg／mL不同浓度的DDP进行培养，模型＋含药血清组是在不同浓度的DDP基础上予以10％保元排毒丸含药血清进行培养。培养24h后分别以荧光显微镜、电镜、流式细胞仪检测细胞凋亡情况。结果：与空白血清组比较，荧光显微镜下模型组凋亡细胞增多，而模型＋含药血清组凋亡细胞数明显减少；电镜下模型组细胞受损明显，而模型＋含药血清组细胞形态基本正常。流式细胞仪检测细胞凋亡率，空白对照组为2．45％；各DDP组明显增加，10μg／mL组和6／μg／mL组分别为31．80％和30．98％，与空白对照组比较差异有统计学意义，P〈0．001；各含药血清组明显减少，DDP 10μg／mL＋含药血清组和DDP 6μg／mL＋含药血清组分别为15．21％和14．27％，与相应模型组比较差异有统计学意义，P〈0．001。模型组bcl-2基因及突变型p53基因的表达均明显降低，相应含药血清组的表达均有所上调。结论：保元排毒丸能减轻顺铂所致LLC—PK1细胞的凋亡，上调凋亡抑制基因bcl-2和突变型p53，可预防或降低顺铂引起的肾毒性。
