油菜和向日葵花粉的成分分析及其蛋白质营养评价

<正> 花粉在古代就曾作为强身保健食品。美、英两国的科学家曾分析了花粉的成分,发现花粉由96种元素组成,其中有维生素、矿物质、酶、蛋白质和某些其它物质。美国明尼苏达大学曾做过花粉对动物的增重实验。当41～150日龄小猪饲料中添加2～3％的玉米花粉时,体重增长明显快于对照组,     

Belt device for simplified CT-guided puncture and biopsy: A technical note

A new radiolucent device for increased accuracy of CT-guided fine-needle punctures permits precise determination of the optimum angle, depth, and position of the fine needle, which can be preset from the data supplied on the CT monitor. Puncture and repeat scans for controlling the tip of the needle can be performed with the patient in a stationary position. The device is designed as a belt that holds a needle holder sheath and a goniometric scale, both of which can be moved to varying positions around the patient.     

Is dietary counselling effective in increasing dietary calcium,protein and energy intake in patients with osteoporotic fractures? A randomized controlled clinical trial

To determine the feasibility of increasing the calcium, protein and calorie intake of osteoporotic fracture patients by repeated dietary counselling delivered by a dietitian, a randomized controlled trial was conducted. Among 189 patients presenting with osteoporotic fractures to an Orthopaedics and Traumatology Department of a large regional hospital, 98 patients were randomized to the intervention group and 91 were randomized to the control group (with usual care). Intervention group received three sessions of dietary counselling with tailored made recommendations over a period of 4 months, while the control group only received dietary assessment and pamphlets on the prevention of osteoporosis. Almost all subjects in both intervention and control groups had calcium intake below the recommended level of 1000 mg at baseline. Half and 60% of subjects in both groups had total energy and protein intake below recommended levels respectively. The mean weights of control and intervention groups at baseline were 51.5 and 50.9 kg respectively, while the body mass index (BMI) were 22.6 (kg m(-2)) and 22.6 (kg m(-2)) respectively. After dietary intervention, significant increase of intake was seen in calcium intake (P = 0.0095 by t-test) in the intervention group. No significant increase was seen in protein or calorie intake. No significant change was observed in the body weight or BMI although there was a positive trend in the intervention group for all these parameters. We concluded that there was general malnutrition in Chinese elderly who presented with osteoporotic fractures. Dietary calcium could be increased by repeated professional dietary counselling. Future studies with longer duration and more objective clinical outcomes will be helpful to further demonstrate the long-term effects of dietary intervention on osteoporosis and other chronic diseases.     

A preliminary study of stress symptoms and nutritional state in children

The aim of this work was to examine the occurrence of stressful events in the lives of children, using the ‘Scale of Infantile Social Readjustment’ (SISR), and the ‘Inventory of Symptoms of Infantile Stress’ (ISIS) to identify the presence of stress symptoms. The results of these evaluations were then used to examine the relationship between the levels of stress and the nutritional state of the children, by correlation. Forty 7–10‐year‐old children were included in the evaluation. From the analysed sample 49 per cent of them were eutrophic (weight/height normal to age), 50 per cent were above weight and 1 per cent was undernourished. Whereas 70 per cent of the girls were eutrophic and 30 per cent were above weight, only 35 per cent of the boys were eutrophic, 60 per cent were above weight and 5 per cent were undernourished. The results obtained in this first study indicated that 45 per cent of eutrophic girls demonstrated symptoms of stress, while 20 per cent of them were asymptomatic (with no symptoms of stress). Of the overweight boys, 30 per cent of them showed symptoms of stress and 35 per cent did not. This study indicated a possible relationship between weight and the symptoms of stress.

婴儿脑损伤早期诊断和早期医学干预探讨

目的探讨婴儿脑损伤筛查专科门诊在早期发现婴儿脑损伤的作用以及神经发育疗法治疗脑损伤的效果。方法采用专科门诊筛查，早期发现脑损伤忠儿。对婴儿脑损伤进行早期诊断和早期综合康复治疗，以临床疗效评估。结果专科门诊对早期发现婴儿脑损伤有意义，88．1％的患儿由门诊筛查发现而被诊断，筛查中应着重注意小婴儿肌张力改变（48％）和运动发育落后（35％），脑损伤中不明原因占18％，1岁以内脑损伤诊断以中枢性发育障碍（89％）、运动落后（11％）为主，治疗以神经发育疗法为主的综合方法，20d一疗程，108例1岁以下脑损伤忠儿治疗效果：显效46．2％，好转47．2％，无效6．6％，总有效率为93.4％，6mo以下疗效显著高于6mo以上脑损伤忠儿。结论婴儿脑损伤专科门诊定期筛查能够早期发现患儿，CDD和MD作为婴儿脑损伤早期诊断的名称是可取的，治疗以神经发育疗法为主，治疗愈早，效果愈好，婴儿脑损伤早期诊断和早期医学干预方法可以在医疗保健机构推广和应用。
