性病诊治中护患关系的伦理学探讨

探讨影响性病诊治中护患关系的伦理学因素,并提出相应的护理对策,以期建立和谐的新型护患关系.护理道德义务、保护性病患者个人隐私、护士的职业进取心、性病患者的疾病知情权等因素是当前影响性病诊疗中护患关系的主要伦理学因素;因此,加强护士的职业道德教育、尊重患者的人格和隐私权、提高自身护理专业水平、普及健康教育等伦理学措施有助于改善护患关系,最终规范性病的诊疗.     

Pharmacokinetics of tacrolimus and mycophenolic acid are altered, but recover at different times during hepatic regeneration in rats.

Hepatic regeneration is very critical to the success of living donor liver transplantation, which allows a reduced size liver to grow in size to accommodate the requirements of both the donor and the recipient. The objectives of this study were to evaluate 1) the hepatic metabolism of the two immunosuppressive drugs, tacrolimus and mycophenolic acid (MPA), and 2) the pharmacokinetics of tacrolimus and mycophenolic acid at various time points after initiation of hepatic regeneration by partial hepatectomy in rats. The hepatic intrinsic clearance of tacrolimus was decreased to 70% and 51% of the control level at the 24th h and the 6th day, respectively, but returned to normal level by day 14. The total body clearance of tacrolimus was reduced transiently but recovered completely by day 18. The hepatic intrinsic clearance of MPA was decreased to 52% and 51% of that in control rats at the 24th h and the 6th day, respectively, but recovered to normal level by day 14. The total body clearance of MPA was reduced at the 24th h but recovered by day 6. The magnitude of reduction in the clearance of tacrolimus and MPA was much smaller than what was predicted from in vitro data. The elimination clearance of MPA glucuronide was also impaired during hepatic regeneration but recovered to normal level with time. In conclusion, the pharmacokinetics of tacrolimus and mycophenolic acid were altered during hepatic regeneration but recovered completely at different rates over time. Caution must be exercised in extrapolating in vitro data to in vivo conditions during hepatic regeneration.     

波依定与洛汀新治疗不同中医证型高血压疗效比较

目的:观察波依定与洛汀新对不同中医证型高血压的疗效是否具有中草药的某些特征,能否按中医辨证选择抗高血压药.方法:按照WHO的标准明确高血压诊断与分级,根据<中药新药临床研究指导原则>分为4型.216例患者随机分为两组,分别给予波依定与洛汀新治疗,疗程4周.分析对总体血压和不同证型血压的影响,以及对不同症状的疗效有无差异.结果:两种药物降低患者总体血压的幅度基本相同;但分层研究,对4种中医证型患者的血压的降低程度明显不同,洛汀新对肝火亢盛型血压降低幅度更明显,波依定对痰湿壅盛型比其它三型降压更好;对阴虚阳亢型和阴阳两虚型两组之间差异无显著性.对各种证型症状的改善作用也显示同样的结果.结论:抗高血压药对不同中医证型高血压的疗效不同,表明西药也同样具有中草药的某些特性,可以根据中医辨证选择抗高血压药.     

Solitary fibrous tumors of the pleura: clinical, radiological, surgical and pathological evaluation.

AIMS: To report a clinicopathological series of cases of solitary fibrous tumor of the pleura from Taiwan. METHODS: Clinical data was collected from a review of medical records and telephone interviewing for follow-up. RESULTS: Eight patients, three men and five women aging from 34 to 71 years, underwent tumor resection and were followed in a period from 7 months to 13.5 years. Six patients underwent standard thoracotomy and two had VATS for tumor excision. Tumors were pathologically benign in seven patients and malignant in one. Patients were all alive with no evidence of tumor recurrence at the time of this report. CONCLUSIONS: One should always consider SFTPs as potentially malignant tumors. Complete resection remains the mainstay of cure. Standard thoracotomy should always be considered when a high suspicion of malignancy is raised, whereas VATS may be a preferred approach for smaller tumors.

米团花色素的提取及其稳定性研究

米团花色素是云南省某些地区居民使用的一种传统黄色天然食用色素.本研究表明,米团花色素在433 nm和326 nm处分别有一个较强吸收峰.稳定性实验表明:该色素对酸、热、光、氧化剂过氧化氢(不加热)、常见金属离子、食盐及食糖等稳定,但在碱性条件或亚硫酸钠存在时不太稳定.此外,加入过氧化氢后加热也会引起其吸光值的显著改变.初步确定米团花色素主要为胺类物质.在正常加工条件下,是一种较理想的天然食用色素.
