CA125测定对某些妇科肿瘤的诊断意义

本文对４０名正常妇女和２０２名妇科肿瘤、宫内膜异位症的患者进行了血清ＣＡ１２５的测定。结果表明９８％正常妇女血清ＣＡ１２５水平＜５０ｕ／ｍｌ，行经期水平高于滤泡期、黄体期和绝经期水平。五组妇科疾病患者血清ＣＡ１２５水平也进行了测定，并观察了２１名卵巢癌患者ＣＡ１２５水平的变化情况。卵巢癌患者ＣＡ１２５水平最高，它与其它疾病组及正常对照组有明显的差异。血清ＣＡ１２５的测定在妇科临床上是有价值的。     

氨氯地平与尼群地平治疗高血压的多中心平行对照研究

采用多中心、随机、单盲、组间、平行对照的方法对488例原发性高血压患者进行氨氯地平或尼群地平4周治疗观察，显示氨氯地平的降压有效率为90．4％，较尼群地平显著为高。不良反应较少，安全性好。每日只需服药1次，剂量5～10mg，方便病人。

125~I－后标记检测DNA－蛋白质交联物的研究

１２５~Ｉ－后标记法是庄志雄等人（１９９４）提出的一种检测ＤＮＡ－蛋白质交联物（ＤＰＣｓ）的新技术，该法在检测离体ＣＨＯ细胞ＤＰＣｓ的实验中已显示出敏感、快速和简便的优点。本研究表明，１２５~Ｉ－后标记法不仅能有效地检出由紫外光和铬酸钾诱导的ＣＨＬ细胞ＤＰＣｓ，并能有效而敏感地检测由铬酸钾和氯化镍引起的大鼠不同组织特别是白细胞ＤＰＣｓ形成的情况，是一种敏感的和可考虑应用于人群调查的ＤＰＣｓ检测方法。     

Osteogenesis imperfecta: A clinical study of the first ten years of life

Summary One hundred twenty-seven children with osteogenesis imperfecta (O.I.) were studied during the first 10 years of life. According to Sillence, 40 patients were assigned to type I, 39 to type III, and 48 to type IV O.I. Centiles for height, weight, and the annual number of fractures could be established for the different types of O.I. The development of the skeletal changes could be documented for the different forms of the disease. At birth, the skeletal changes were significantly more severe in type III than in type IV patients. During the first 10 years of life the number of fractures, extent of skeletal deformities, and growth retardation did not differ between types III and IV. Only fracture nonunion, dentinogenesis imperfecta, and congenital cardiac malformations were more frequent in type III than in type IV. Papillary calcifications of the kidney and kidney stones were diagnosed in 4 type III and 2 type IV patients. Hemihypertrophy of the body developed, in 2 type I patients. Although types III and IV patients suffered from severe short stature, serum insulin-like growth factor (IGF) I was in the normal range.     

Primary peritoneal carcinoma in a UK cancer center: comparison with advanced ovarian carcinoma over a 5-year period

Abstract.   Jaaback KS, Ludeman L, Clayton NL, Hirschowitz L. Primary peritoneal carcinoma in a UK cancer center: comparison with advanced ovarian carcinoma over a 5-year period. Int J Gynecol Cancer 2006; 16(Suppl. 1): 123–128.
The relative incidence of primary peritoneal carcinoma (PPCa) and advanced (FIGO stage III or IV) ovarian serous carcinoma (AOSCa) was assessed over 5 years at a UK cancer center, and the sociodemographic, clinical, and survival data were compared. There were 23 women with PPCa and 55 with AOSCa. The ratio of PPCa:AOSCa was higher than previously reported. No statistical difference was found between the two groups with regard to age (mean 64.43 vs 64.07 years, P = 0.9), parity (1.6 vs 1.8, P = 1.0), personal/family history of another malignancy (although five patients with AOSCa but none with PPCa had personal histories of breast cancer), or serum CA125, CA19.9, and carcinoembryonic antigen (CEA) levels. Similar numbers in both groups had malignant ascites, although 5.8% of patients with AOSCa but none with PPCa had negative cytology. Tumor grade, stage, treatment, and survival were similar (median 586 vs 641 days, P = 0.66). This analysis of the largest published UK series of patients with PPCa does not support previous reports that patients with PPCa are older than those with AOSCa and have a worse prognosis; it suggests that both groups have similar sociodemographic characteristics, clinical profiles, and survival.     

人参二醇组皂甙对精索静脉曲张大鼠的保护作用及其机制

把56只成年Wistar大鼠分为如下3组:①精索静脉曲张组(VG)30只;②精索静脉曲张人参二醇组皂甙组(VPG)8只;③假手术组(SOG)18只。实验结果表明,人参二醇组皂甙可显著提高精索静脉曲张大鼠睾丸ACE活力并降低睾丸LPO含量,但3组动物睾丸的SOD水平无明显差异。作者认为人参二醇组皂甙可能是通过减少LPO产生以提高ACE活力,从而实现对精索静脉曲张大鼠的保护作用。
