The publication rates of presentations at major Spine Specialty Society meetings (NASS, SRS, ISSLS)

STUDY DESIGN: A review of all the presentations at three major spine specialty meetings held over a 3-year period. OBJECTIVES: To determine the rate of publication in peer-reviewed journals after presentations at major spine meetings conducted annually by the following three organizations: North American Spine Society (NASS), Scoliosis Research Society (SRS), and International Society for the Study of the Lumbar Spine (ISSLS). SUMMARY OF BACKGROUND DATA: The rate of publication for presentations at national and international meetings has been determined for medical and surgical subspecialties. This rate has been used to judge the quality of the content of the meetings and to determine the validity of the research presentations. METHODS: All presentations either in poster or oral presentation form were entered into a database covering a 3-year period for spine specialty meetings conducted annually by the following three organizations: NASS 1990 to 1992, SRS 1991 to 1993, and ISSLS 1991 to 1993. A computer search for each abstract was performed with the Melvyl Medline Plus database to determine if the abstract had been published in a peer-reviewed journal from 1990 to the end of 1997. Publication rates for presentations at these three meetings were determined over a 3-year period. RESULTS: A total of 1186 abstracts were listed over a 3-year period in the final programs of these three meetings for the years 1991 to 1993 (SRS, ISSLS) and 1990 to 1992 (NASS). Of these 1186 abstracts, 516 were published in peer-reviewed journals, giving an overall publication rate of 43.5%. The publication rates for the three different meetings (NASS, SRS, ISSLS) were similar, with values of 40%, 47%, and 45% respectively. More than 90% of the publications resulting from these meetings were published within a period of 4 years from the data of the meeting. CONCLUSIONS: The publication rates of presentations at three major spine specialty meetings are high and quite comparable with the publication rates of meetings in other medical subspecialties. This reflects the high quality of the meeting programs and validates their selection process.     

胃肠道癌手术与门静脉单细胞转移的相关性研究

目的 进一步了解在胃癌、大肠癌的根治过程中,手术对单细胞转移的影响。方法 １７２例２分２组,阳性受检组１１１例,先结扎肿瘤区引渡以血和的阴性对照组６１例。开腹探后将导管置入门静脉抽取血标本,抗上皮细胞膜克隆抗体为探针,ＡＢＣ免疫组化法检测门静脉癌细胞。结果 阳性受检组１１１例患者中有７２例发现肿瘤细胞、阳性率为６４．９％,有性对照组的６１例仅发现１３例,阳性率为２１．３％,两组且间差异有显著性,     

图像细胞分析与癌基因检测辅助诊断直肠癌

目的提高直肠癌术前活检的诊断率。方法对１７例术前活检未证实为直肠癌的患者的活检标本（实验组）和１５例正常肠粘膜活检标本（对照组）的石蜡包埋块进行常规病理检查、细胞图像分析（ＩＣＭ）、ｐ５３与ｒａｓ癌基因产物检测。结果实验组ＩＣＭ结果５３％为异倍体,癌基因检测结果ｐ５３与ｒａｓ基因表达阳性率分别为７１％、４７％。对照组的ＩＣＭ与癌基因检测结果均阴性。实验组中,常规病理检查１１例为不典型增生,５例为慢性炎症。常规病理检查为不典型增生的病例中经ＩＣＭ、癌基因检测８例为异倍体,ｐ５３与ｒａｓ基因表达阳性分别为１１和７例;慢性炎症病例中则既无异倍体,又无ｐ５３与ｒａｓ基因表达,二者之间,异倍体和两种基因表达阳性率差异均有显著意义（Ｐ＜００５）。ＩＣＭ与癌基因检测结果有较好的一致性。结论ＩＣＭ与癌基因检测,可以作为常规病理的补充,提高直肠良恶性病变的鉴别力。     

窥镜下激光治疗前列腺增生症

目的 评价经尿道激光前列腺切除术（ＴＵＬＰ）的疗效及其与前列腺大小的关系。方法 回顾分析了１９８８年至１９９８年１０年,采用ＴＵＬＰ治疗的４６９例前列腺增生症患者对手术技术、手术前后的症关改善情况进行比较,并对２３３例符合条件的患者ＴＵＬＰ手术效果与前列腺大小的相关性进行了研究。结果 ４６９例患者前列腺症状评分（ＩＰＳＳ）平均值由术前的２６．７降到术后的１４．２;最大尿流率平均值由６．２ｍｌ／ｓ上     

联合内分泌治疗对前列腺和睾丸的影响

目的 探讨抑那通和缓退瘤联合治疗对正常前列腺,增生的前列腺（ＢＰＨ）和前列腺癌以及睾丸的作用。方法 对１６例接受联合内分泌治疗至少３个月且有治疗前后病理资料的前列腺癌患者的标本进行了系统的病理学检查。对内分泌治疗后的睾丸标本与同龄未接受治疗的进行对照研究。结果 １４例内分泌治疗后的前列腺标本２例未见残存癌灶,９例对治疗有明显的反应;３例对治疗反应差,治疗并未降低前列腺癌的病理分期。３例内分泌治疗后     

Paget病19例

目的 提高对Ｐａｇｅｔ病的诊治水平。方法 回顾性分析１９８７年至１９９７年收治的１９例Ｐａｇｅｔ病的临床表现及诊治方法。结果 本组乳腺Ｐａｇｅｔ病６例,乳腺外１３例,其中阴茎,阴囊１１例,腹股沟处１例,肛周肛管１例。随访时间０．５－１１年,平均５年４个月,随访中３例复发者,其截端切片病理检查均可见病变组织,另１例死于其他疾病。
