如何上好医学生药品质量选修课

医学生在以后的工作中会经常接触到药品，而药品质量的好坏直接关系到患者的生命安全，因此在医学生中开设药品质量选修课非常必要。本文从教学方法、教学手段、教学内容的衔接等方面提出了一些观点和具体方法。     

社区卫生服务信息系统功能建模研究

理顺功能关系、理清业务流程是构建社区卫生服务信息系统的前提和基础,功能建模是理顺功能关系的一个重要手段。在研究现有的各种功能分析方法的基础上,本文以IDEF0模型方法为基础,提出了社区卫生服务信息系统功能建模方法。通过建立功能、数据和约束之间的内在联系,为系统的功能设计和数据分析提供了基础。     

米利酮对豚鼠心乳头肌及主动脉条的作用

米利酮是非洋地黄，非儿茶酚胺类强心药，具有明显的正性肌力和扩血管作用。国外用于治疗难治性心衰及洋地黄中毒的心衰病人。本文用豚鼠乳头肌及主动脉条进行实验，结果表明合成与进口米利酮的正性肌力作用效价相同，对抗去甲肾上腺素缩血管的作用也等同。     

Osteogenic Sarcoma of the Left Atrium

A primary cardiac osteogenic sarcoma is described in a patient presenting with a left atrial obstructive lesion. Wide surgical excision was possible with left atrial reconstruction and mitral valve replacement. The patient survived the operation and was symptom free for 1 year, finally dying at 18 months of cerebral metastases.     

Needle tract recurrences after closed biopsy for sarcoma: Three cases and review of the literature

Background: Percutaneous closed needle biopsy of musculoskeletal neoplasms has gained in popularity. However, it remains controversial whether or not to resect the needle tract for fear of a local recurrence. A single published case report exists, noting the lone tract recurrence of an extremity skeletal osteosarcoma. Methods: We report on three additional individuals who demonstrated that tract local recurrences may occur after a closed needle biopsy for nonosteosarcoma, nonextremity sarcomas. For perspective, the world literature is reviewed to identify tract recurrences for other malignancies and the results of needle biopsy in musculoskeletal neoplasms. Results: Eighty-nine percent of needle tract local recurrences occur when carcinomas are subjected to biopsy, as reported in the literature. Forty-seven cases since 1950 are described representing essentially all tumor types. The nature of musculoskeletal neoplasms makes closed biopsy more difficult than for softer, more homogeneous, and easier to access neoplasms. Conclusions: Local recurrences of sarcoma may occur in closed needle biopsy tracts. Strong consideration should be given to open biopsy and tract resection.     

Solid variant of odontogenic keratocyst

A case of an unusual lesion from the maxilla is presented. Macroscopically, the lesion was solid and histologically consisted of 'multiple separate keratocysts' of varying size that infiltrated into the surrounding bone and soft tissues. Panoramic image and CT scans showed a multilocular honeycomb ill-defined radiolucency with infiltration into the maxillary sinus and floor of orbit. This lesion should be differentiated from similar odontogenic lesions, such as keratoameloblastoma and papilliferous keratoameloblastoma. As there was no evidence of follicles, islands of ameloblastoma, or papilliferous structures in the entire specimen, the lesion could not be diagnosed as either a keratoameloblastoma or a papilliferous keratoameloblastoma. The invasive and destructive growth behavior, the histopathological features, and the histochemical pattern of the collagen stroma imply that this solid lesion is a neoplasia. It is suggested that the proper term for this lesion is solid variant of odontogenic keratocyst.     

甲状腺病变患者血清Leptin的浓度变化

目的探讨甲状腺病变患者血清瘦素(leptin)浓度的变化及意义.方法本文用放射免疫分析(RIA)方法测定了114例甲状腺病变患者血清Leptin和总睾酮(TT)的浓度.结果统计学处理结果显示各病变组男性与正常对照组男性间,Leptin和TT的浓度差异均有显著性意义.结论血清Leptin的浓度变化可作为了解甲状腺病变患者营养状况的辅助指标.     

中美护理本科《护理学基础》课程设置的比较研究

[目的]对中美护理本科《护理学基础》课程设置情况进行比较,为中国护理本科《护理学基础》课程改革提供可借鉴的科学依据。[方法]选取美国和中国各20所全日制护理院校对其护理专业本科课程《护理学基础》的开设情况进行统计分析。[结果]美国护理本科有65.00%的院校开设《护理学基础》,其实践学时和理论学时数分别为30学时~135学时和20学时~56学时,两者比值为1.00~3.00;中国护理本科院校均开设《护理学基础》,其实践学时和理论学时数分别为18学时~268学时和54学时~128学时,两者比值为0.33~2.31。[结论]中美护理本科《护理学基础》课程开设情况存在一定差异,我国《护理学基础》有内容较简单、操作多、理论少、学时数较多特点;而美国《护理学基础》学时数较少,实践学时所占比例较大。     

Chronic recurrent multifocal osteomyelitis and psoriasis—A report of a new association and review of related disorders

In summary, we have described two patients with CRMO and psoriasis, and have reviewed the musculoskeletal manifestations associated with pustular eruptions of the palms and soles. In view of the frequent occurrence of PPP in patients with CRMO, we suggest that the occurrence of psoriasis in our two patients is more than coincidence, and that noninfectious, inflammatory lesions of bone may be another musculoskeletal manifestation of psoriasis. This rare association, as well as the association of PPP with disorders associated with new bone formation, may shed new insights on the relatively common finding of periosteal elevation associated with psoriatic arthritis and the occasional severe juxta-articular osteolytic destructive bone lesions seen in psoriatic arthritis.     

Capsaicin cough sensitivity in allergic asthmatic patients increases during the birch pollen season.

BACKGROUND: A change in neural responsiveness may occur as the result of allergic inflammation in the lower airways as well as in the upper airways. In the lower airways, capsaicin cough sensitivity is known to reflect sensory neural reactivity. OBJECTIVE: The aim of this study was to establish whether allergic inflammation changes airway neural sensory reactivity during prolonged allergen exposure. METHODS: Ten nonsmoking patients with birch pollen-allergic asthma performed a capsaicin inhalation challenge twice, once in the off-pollen season and once during the pollen season. The number of coughs and symptoms induced by capsaicin were recorded and compared with those of healthy control subjects. RESULTS: The response to capsaicin, expressed as number of coughs, increased in a dose-dependent manner during both tests. Before the season, the response was similar to that of healthy control subjects, but during the pollen season, the reactivity was significantly increased. Variations in forced expiratory volume in 1 second were not significant before and after each challenge, and values did not change during the pollen season as compared with the winter season. CONCLUSIONS: Sensory reactivity in allergic asthmatic patients may be increased during prolonged allergen exposure as during the pollen season. This finding suggests that allergic inflammation in the lower and/or upper airways may trigger neurogenic mechanisms of significant clinical importance.
