目的:探讨乙型肝炎患者血清IL-2、sIL-2R、IL-13及PDGF水平的变化及测定的临床意义。方法:150例乙型肝炎患者分为3组(急性肝炎组20例、慢性肝炎组90例和重型肝炎组40例);设健康人45名作为对照组。前2项血清标志物均采用放射免疫分析;后2项血清指标则采用酶联免疫吸附试验测定。将测定结果进行统计分析。结果:本文测定数值显示,血清IL-2水平急性肝炎患者组水平与对照组比较略有降低,但无统计学意义(P〉0.05);慢性肝炎和重型肝炎2组患者该指标水平则均显著低于对照组(P均〈0.05)。sIL-2R水平显示急性、慢性及重型肝炎3组患者均非常显著地高于对照组(P均〈0.01),且发现其递增规律与肝炎病情的严重程度呈明显的平行关系。IL-13水平测定结果也显示3组患者均显著高于对照组(P均〈0.05)。PDGF测定值显示,急性肝炎组水平显著高于对照组(P〈0.05),慢性肝炎和重型肝炎2组水平则较对照组升高更为显著(P均〈0.01)。其水平的递增关系也与病情的严重程度相一致。结论:本文患者4项血清指标水平的变化与乙型肝炎的发病及病情进展有关;其测定有助于了解本病的发生机制和预后评估。 相似文献

These guidelines on flexible bronchoscopy depict important clues to be known and taken into account while practicing flexible bronchoscopy, in adult, except in emergency situations. This is a practical clarification. Safety conditions, complications, anesthesia, infectious risks, cleaning and disinfection are detailed from a review of the literature. Intensive care practice of bronchoscopy requires more attention due to higher risks patients and is discussed extensively. Standards and performances of the various sampling techniques complete this work. Indications for bronchoscopy, therapeutic and paediatric bronchoscopy are not covered in these guidelines. 相似文献

Clinical competence in myocardial perfusion scintigraphic stress testing: general training guidelines and assessment 总被引:1,自引:0,他引:1

The suggestion by the National Institute for Clinical Excellence (NICE) to more than triple the number of myocardial perfusion scintigraphy (MPS) procedures carried out by the NHS each year is a challenge both in terms of numbers of gamma cameras available to carry out the scans and qualified staff to supervise stress tests. In the past, exercise and pharmacological stress testing have been supervised only by doctors but, increasingly, this is taken on by suitably trained non-medical professionals such as nurses, radiographers and clinical technologists. The expansion of the numbers of non-medical professionals qualified to supervise stress testing will be key to meeting NICE's recommendations. This paper sets out how potential new stressors should be identified, what their training should cover and discusses the standards of competence they should meet. It provides guidelines for training non-medical stressors to perform a safe and efficient stress test during MPS and advice for maintaining competency. 相似文献

The female athlete triad (Triad) refers to the interrelationships among energy availability, menstrual function, and bone mineral density, which may have clinical manifestations including eating disorders, functional hypothalamic amenorrhea, and osteoporosis. With proper nutrition, these same relationships promote robust health. Athletes are distributed along a spectrum between health and disease, and those at the pathological end may not exhibit all these clinical conditions simultaneously. Energy availability is defined as dietary energy intake minus exercise energy expenditure. Low energy availability appears to be the factor that impairs reproductive and skeletal health in the Triad, and it may be inadvertent, intentional, or psychopathological. Most effects appear to occur below an energy availability of 30 kcal.kg(-1) of fat-free mass per day. Restrictive eating behaviors practiced by girls and women in sports or physical activities that emphasize leanness are of special concern. For prevention and early intervention, education of athletes, parents, coaches, trainers, judges, and administrators is a priority. Athletes should be assessed for the Triad at the preparticipation physical and/or annual health screening exam, and whenever an athlete presents with any of the Triad's clinical conditions. Sport administrators should also consider rule changes to discourage unhealthy weight loss practices. A multidisciplinary treatment team should include a physician or other health-care professional, a registered dietitian, and, for athletes with eating disorders, a mental health practitioner. Additional valuable team members may include a certified athletic trainer, an exercise physiologist, and the athlete's coach, parents and other family members. The first aim of treatment for any Triad component is to increase energy availability by increasing energy intake and/or reducing exercise energy expenditure. Nutrition counseling and monitoring are sufficient interventions for many athletes, but eating disorders warrant psychotherapy. Athletes with eating disorders should be required to meet established criteria to continue exercising, and their training and competition may need to be modified. No pharmacological agent adequately restores bone loss or corrects metabolic abnormalities that impair health and performance in athletes with functional hypothalamic amenorrhea. 相似文献

Cardiopulmonary resuscitation in the mountains usually has to be performed under difficult and hostile circumstances and sometimes for extended periods of time. Therefore, mountain rescuers should have the ability and the appropriate equipment to perform prolonged, efficient, and safe ventilation. Members of the International Commission for Mountain Emergency Medicine (ICAR MEDCOM) discussed the results of a literature review, focusing on the advantages and disadvantages of common ventilation techniques in basic life support and their training methods with specific respect to use in mountain rescue, and recommendations were proposed. Bystanders fear the potential risk of infection and lack the willingness to perform mouth-to-mouth ventilation, though the risk of infection is low. Mouth-to-mouth ventilation remains the standard technique for bystander ventilation and, in the absence of a barrier device, bystanders should not hesitate to ventilate a patient by this technique. For mountain rescue teams, we encourage the use of a barrier device for artificial ventilation. Mouth-to-mask ventilation devices are most likely to fulfill the requirements of being safe, simple, and efficient in the hands of a basic-trained rescuer. The use of a mouth-to-mask ventilation device is recommended for out-of-hospital ventilation in the mountains and should be part of the mountain rescuer's standard equipment. Bag-valve-mask ventilation is efficient, if performed by well-trained rescuers, but it leads to a low ventilation quality in the hands of a less experienced rescuer. It should be emphasized that regular training every 6 to 12 months is necessary to perform proper ventilation. 相似文献
