研究生主观幸福感与人格特征相关研究

目的探讨研究生的主观幸福感与人格的关系。方法采用艾森克人格问卷量表与总体主观幸福感量表（GWB）对200名研究生进行测验。结果（1）在专业、性别、年级、年龄、婚姻状况上及来源上，研究生的主观幸福感不存在显著差异。（2）相关分析表明外向性人格纬度与总体幸福感存在显著的正相关，神经质与总体幸福感存在显著的负相关。稳定外向型和稳定内向型人格的总体幸福感水平最高，其次是不稳定外向型人格，总体幸福感水平最低的是不稳定内向型人格。结论外向性与神经质等人格特征是影响研究生幸福感的重要因素。     

面部烧伤病人感染危险因素的分析及护理

面部是人体的暴露部位,在烧伤病中占有较大比例。烧伤后很容易引起组织毁损及吸入性损伤,反复感染影响创面愈合,伤愈后常留有色素沉着、瘢痕增生、睑外翻、唇外翻等后遗症,影响面部美观及五官功能,给病人带来长期精神痛苦。我院1998年—2001年面部烧伤病人感染率为6.09%。因此,2002年—2005年,我科护理人员加强面部烧伤感染的防护措施,使其感染率下降到2.49%。正确的护理干预可以有效预防病人感染,减轻各种并发症的发生。现对面部烧伤病人的护理干预报告如下。1临床资料我科2002年—2005年共收治烧伤病人558例,其中面部烧伤281例,男195例,女…

Inhibition of the ubiquitin-proteasome system: a new avenue for atherosclerosis.

BACKGROUND: The ubiquitin-proteasome system (UPS) is thought to be functionally active in atherosclerosis (AS) lesions. Aspirin was found to be a potent inhibitor of the UPS in some tumour studies; however, its effect on AS remains to be demonstrated in vivo. METHODS: New Zealand rabbits were placed on a normal diet (N) or on a normal diet with aspirin (NI) or on an atherogenic diet without (H) or with aspirin (HI) for 12 weeks. Proteasome activity, concentrations of plasma lipids and levels of peroxidation were determined. Ubiquitin/ubiquitin-conjugates (Ub), IkappaBalpha, phosphorylated IkappaB (pIkappaBalpha) and p65 were investigated by Western blotting or immunochemistry. RESULTS: Concentrations of plasma lipids and peroxidation levels were higher in H or HI vs. N or NI. Histological analysis showed that atheroma was increased in H. Ub and IkappaBalpha were mainly localised in subendothelium and media vascular smooth muscle cells. Western blots revealed that Ub, IkappaBalpha, and pIkappaBalpha were increased, whereas p65 was lower in HI vs. H. The activity of the 20S proteasome was functionally active in H vs. N, NI or HI, while the 26S proteasome was not affected in any of the groups. CONCLUSIONS: Aspirin can attenuate the pathogenesis of atheroma formation, the degradation of IkappaBalpha and pIkappaBalpha, and lower the expression of p65, indicating that its therapeutic effects on AS may be via inhibition of the UPS.     

电针治疗周围性面瘫疗效观察

目的:寻找能提高治疗周围性面瘫疗效的适宜的电针波型.方法:将147例周围性面瘫患者随机分为治疗组和对照组,治疗组进行穴位分组,电针波型先用连续波后用疏密波治疗;对照组穴位不分组,并单纯采用连续波治疗.结果:两组的总有效率和痊愈所用时间经统计学处理,差异有非常显著性意义(P＜0.01).结论:在电针治疗周围性面瘫中,将疏密波和连续波配合使用,效果显著优于单纯使用连续波者.

Bone growth patterns in Chinese children and adolescents: a 6-year follow-up study provides evidence for sexual dimorphism and tracking

Summary We prospectively examined bone growth patterns in 894 children aged 6–17 years at the baseline visit, with a 6-year follow-up. Results show bone “tracking” over a six-year interval and sexual dimorphism of bone attained levels and timing of peak bone growth. Our findings underscore childhood and adolescence as critical periods for building bone and developing gender differences. Introduction Bone growth patterns were prospectively examined in 894 Chinese children (496 males), aged 6–17 yrs, from a population-based twin cohort. Whole-body bone area (BA), bone mineral content (BMC), and bone mineral density (BMD) were measured by DEXA at baseline and a 6-yr follow-up. Methods Graphic smoothing plots and generalized estimating equations were used to model bone attained levels, growth, and “tracking”. Results Attained levels of BMC and BA increased curvilinearly with age. Male attained levels were higher than females after age ∼15 yr, but BMD was lower between 13–17 yrs (Tanner stage I to IV). In both genders, peak BMC and BMD growth lagged ∼2 yrs behind peak BA growth, which lagged 2 yrs behind peak height growth. Peak bone growth occurred 1–3 yrs later in males. Over the 6-yr follow-up, all bone measurements “tracked”, but “shifting” across ranks also occurred, and baseline tertile ranking influenced bone growth. Females with early menarche had higher attained levels than females with late menarche at age 12–13 yrs. Conclusion Our findings confirm and expand previous studies on peak bone growth conducted in Caucasian cohorts, particularly sexually dimorphic and maturational effects. The significant “tracking” of bone measurements in this 6-yr follow-up study underscores the importance that osteoporosis prevention should begin in childhood and adolescence.
