目的：了解青岛地区临床分离的重要革兰阴性杆菌的耐药情况以指导合理用药。方法：2001年青岛3家医院临床分离的5种革兰阴性杆菌用Kirby-Bauer法进行药敏试验。结果：5种病原菌均占3家医院革兰阴性杆菌分离率的前5位，大肠埃希菌对氟喹诺酮类药物的耐药率达60％－87％，细菌对亚胺培南均呈高度敏感，但铜绿假单胞菌耐亚胺培南株占25．8％，头孢他啶的抗菌活性是三代头孢菌素中最高的；复方酶抑制剂表现出良好的抗菌活性。结论：细菌耐药问题仍是目前临床的严重问题，地域性的耐药性监测是必要的。     

人端粒酶RNA的cDNA探针制备及其对胃粘膜细胞端粒酶RNA表达的检测

目的 建立人端粒酶RNA表达的检测方法。方法 制备人端粒酶RNA，(human telomeraseRNA，hTR)的cDNA探针，分别应用RNA斑点杂交与端粒重复序列扩增法(TRAP)分析检测不同胃粘膜的端粒酶RNA的表达与端粒酶活性。结果 人端粒酶RNA的cDNA探针制备成功。18例活检胃癌组织及45例手术胃癌组织RNA斑点杂交检测的阳性率均为l00％，相应TRAP分析的阳性率分别为88．89％、86．67％，低于RNA斑点杂交(P＜0．05)。同时RNA斑点杂交结果提示在非癌胃组织中随着肠化程度增高人端粒酶RNA表达也增强。结论 RNA斑点杂交检测人端粒酶RNA，具有高度的敏感性和特异性，弥补了TRAP分析敏感性不足的缺点。     

DNA-Methylierung von monohalogenierten Methanen in F-344 Ratten

Monohalogenated methanes (methyl chloride, methyl bromide and methyl iodide) are mutagenic and carcinogenic. The possible mechanism of these effects, DNA methylation, was studied. DNA adducts from orgnas of F344 rats exposed to these chemicals were separated and identified with high performance liquid chromatography (HPLC) and gaschro-matography/massspectrometry (GC/ MS). DNA adducts, 7-methylguanine (7-MeG) and O⁶-Methylguanine(0⁸-MeG), incorporation of¹⁴C into de novo synthesis of nucleobases could be observed in enzymatic DNA hydrolysates by HPLC and determination of the radioactivity in the fractions. The formation of DNA add,ue,ts in the studied organs was only quantitatively different. The formation of O⁶-MeG was further pioved by analysing the acidic hydrolysates using HPLC with non-radioactive O⁶MeG as internal standard. 7-MeG and 3-MeA were identified with GC/MS analysis.     

非脱垂子宫经腹、阴式全切除术临床比较

目的 探讨非脱垂子宫经阴道与经腹全切术的临床比较。方法 2000年5月～2001年1月对阴式子宫全切术 (TVH)28例及腹式子宫全切术 (TAH)35例分为两组进行手术 ,对临床指标进行观察比较。结果 28例TVH手术均成功。平均重量255g(120～510g)。与TAH手术比较 ,其术后病率、肛门排气时间及术后住院天数有显著性差异 ( p<0.001及 p<0.05) ,但其手术时间及术中出血量无显著性差异 ( p>0.05)。结论 随着微创手术的开展 ,利用阴道天然孔道 ,经阴道切除较大的子宫是有效和安全的 ,手术的成功与术者经验、技术及子宫活动度有关 ,有合适器械也是手术成功的因素。     

放射性肝纤维化过程的定量研究

经＾６０Ｃｏγ线照射大鼠肝区，通过光镜、电镜和图像分析仪、宣研究了照后１年肝脏的病理改变。结果表明，３０Ｇｙ组在照射后１年内逐渐发生了放射性肝纤维化病变。在肝纤维化发生过程中，肝细胞内糖原颗凿含量进行性减少，间质中胶原纤维含量进行性增加，网状纤维于照射１－３个月呈进行性增加。     

选择性环氧化酶—2抑制剂的研究现状及应用评价

选择性环氧化酶（COX）-2抑制剂可有效地治疗炎症，同时避免或减轻由于抑制COX-1而导致的毒副作用。有乐观的临床应用前景，但其不良反应亦不容忽视，寻找临床评价好的选择性COX-2抑制剂是当前非甾体类抗类药物研究的重点。     

本科护士规范化培训的探讨

An etiological and clinicopathological study of early syphilis in oropharynx]

OBJECTIVE: To investigate the characteristics of the early stage treponema pallidum infected tissue in ear, nose, oropharynx and larynx and to raise relevance ratio of syphilis in nose and oropharynx and enhance doctor's self-protection awareness. METHODS: The histopathologic characteristics were studied by using HE staining, Warthin-Starry (W-S) staining was adopted to examine the treponema pallidum(TP) in lesion issue and its exudates smear for 12 cases biopsy tissues of suspicious syphilis. The diagnosis was confirmed by venereal disease research laboratory (VDRL), rapid plasma reagin circle test(RPR), treponema pallidum hemagglutination test(TPHA) and fluorescent treponemal antibody-absorption test (FTA-ABS). Treat with curing syphilis methods which published by nation. RESULTS: In the 12 cases mucous membrane specimen, the squamous epithelium proliferated, neutrophilic granulocyte infiltrated, within inherent membrane generous plasmacyte and lymphocyte infiltrated. W-S staining: plenty of treponema pallidum were found inside mucous membrane epithelium and exudate smear. Serology examination: 11 cases VDRL(++++), 7 cases RPR (+), 11 cases TPHA(+), 1 case FTA-ABS(+). After systemic treatment, 11 cases are clinically recovered. All patients serology become negative. CONCLUSION: W-S staining method can directly demonstrate histopathologic characteristics in early syphilis, in intrinsic membrane numerous plasmacyte infiltration. Combining with specific syphilis serology examination could increase diagnosis rate of syphilis in nose and oropharynx.
