Pneumatization of perpendicular plate of the ethmoid bone and mucocele]

OBJECTIVE: To find out the prevalence of pneumatization of perpendicular plate of the ethmoid bone, and to discuss the diagnosis and management of perpendicular plate mucocele (nasal septal mucocele). METHODS: The CT data from 32 patients with septal deviation were reviewed, and an unusual case of perpendicular plate mucocele was reported. RESULTS: Six cases (6/32, 18%) were found to have pneumatization of perpendicular plate of the ethmoid bone, with 2 located in the anterior portion (frontal-septal pneumatization), and 4 located in the posterior portion (spheno-septal pneumatization). A patient with perpendicular plate mucocele was treated by the technique of marsupialization under nasal endoscope. This patient was followed-up for 10 months without recurrence. CONCLUSION: As a kind of variation of nasal septum, the clinical significance of pneumatization of perpendicular plate should be emphasized. We reported the first case of perpendicular plate mucocele, originated possibly from the pneumatization of perpendicular plate of the ethmoid bone. Marsupialization under endoscope was considered to be the initial management for this unusual disease.     

论中医诊治非典型肺炎

本文回顾了50年来我国中医防治流行性乙型脑炎、麻疹、流行性出血热等流行性病毒疾病获得成功的经验，认为中医理论不把着力点放在对病原体的认识上，而是注重病原体侵入人体、病证斗争所表现的证候的辨证论治。作者提出诊治非典型肺炎的理论依据与特色。根据广东省中医院收治非典患者112例的临床观察，认为该病属中医春温温热疾病的范畴，并提出定名为春温病伏温证。本文详细记载该院中医治疗方案和典型医案。

1999至2001年广州地区临床常见肠杆菌科细菌耐药性监测结果分析

目的 了解临床分离常见肠杆菌科细菌的耐药性。方法 统一采用纸片扩散法进行实验，以美国NCCLS文件为判断标准，每次监测均有质控数据。结果 共有11家广州市三级甲等医院实验室参加耐药性监测，三年共统计临床常见肠杆菌科细菌3147株。结论 对肠杆菌科细菌，亚胺培南的耐药率最低，可考虑为临床首选药物，阿米卡星、头孢他啶耐药率相对较低，可选择用药。庆大霉素的耐药率有逐年下降的趋势，将来可能成为临床一线药。而磺胺甲噁唑／甲氧苄啶、四环素、萘啶酸等耐药率相对较高，应慎用。氨节西林的耐药率很高，应避免使用。     

葛根素注射液与输液配伍的稳定性考察

目的　用正交法考察葛根素与 5 %葡萄糖注射液、0 9%氯化钠注射液、葡萄糖氯化钠注射液输液配伍后的稳定性。方法　用正交设计法 ,以葛根素的稳定性为考察指标 ,以浓度、温度、时间、输液种类为可变因素 ,选用L9(34)表进行实验 ,用紫外分光光度法测定其含量。结果　浓度、温度、时间、输液种类对葛根素的稳定性未产生显著性差异。结论　在低温 (4±1℃ )、常温 (17± 1℃ )、高温 (37± 1℃ )下 ,葛根素注射液与各输液均可配伍使用。

Clinical Analysis of 57 Patients with Ovarian Dysgerminoma

Objective  Ovarian dysgerminoma is an uncommon ovarian malignancy, Its clinicai features are special and there are many factors affecting its prognosis. If treated properly, the patient can be cured. Otherwise it may endanger the patient’s life. The aim of this study is to investigate the clinical features and factors related to prognosis of ovarian dysgerminoma. Methods  Data from 57 patients with pure ovarian dysgerminoma were analyzed retrospectively. The patients were admitted to the Cancer Center, Sun Yat-sen University from January 1.1964 to December 31, 2000. Results  The main clinical features were abdominal mass (56.1% ), abdominal pain (21.1% ), abdominal swelling (17.5%.), vaginal bleeding (5.3% )and genital tract abnormalities (5.3%). Twenty-six patients had stage I diseases, 8 stage II.9 stage III.1 stage IV and 13 recurrent and persistent diseases. The uterus was involved in 41.2% of patients with stage II -III diseases. Combined modality was given to 52 cases and a single-method treatment to 5 cases. The total overall 5 and 10-year survival rates for stages I-IV was 80.1 % and 70.0% respectively. The 5-year survival rate for stage I was 100%, stage II 55.2%. stage III 55.6% and stage IV 0%; for recurrent and persistent diseases, 72.7%. The stage I group of 12 patients. received adnexectomy and 14 patients underwent hysterectomy and adnexa removal. There was no significant difference between the 5 and 10-year survival rates (all 100%). Of the 23 patients in the stage I group to whom oniy chemotherapy was given after operation, 19 cases received 3 or more courses and were well without recurrence; 4 patients received only one course and one of them recurred 21 months after the operation. In the group of stages II and III cases, the 5-year survival rate was 86.7% for those whose chemotherapy courses were 3≥ 4 and 25.0% for patients who received less than 4 courses of chemotherapy (P<0.05). Conclusions  The prognosis of ovarian dysgerminoma is closely related to the disease stage and treatment modality. A fertility-preserving operation can be considered in early -staged patients, but caution needs to be exercised in the middle to late staged cases. Good results can be achieved with an operation-based combined modality in recurrent patients.
