选择性髂内动脉结扎与栓塞对盆腔血供的影响

目的：旨在探讨选择性髂内动脉结扎与栓塞两种方法对盆腔血供的影响。方法：将两组犬在膀胱上动脉分支以下之髂内动脉分别行结扎与栓塞，对比观察两组膀胱创面出血、盆腔动脉造影及盆腔脏器组织学变化，以确定其盆腔脏器的血供情况。结果：①结扎组膀胱创面出血明显大于栓塞组；②结扎组髂内动脉侧支循环建立时间明显早于且数目多于栓塞组；③两组盆腔脏器均未见缺血坏死。结论：栓塞组阻断髂内动脉侧支循环的数目多于结扎组，故对盆腔血供的影响大于结扎组。避免髂内动脉阻断范围过广可减少盆腔脏器缺血坏死的机会。     

Ⅰ期非小细胞肺癌淋巴结微转移规律的研究

目的探讨几个问题：（1）Ⅰ期非小细胞肺癌淋巴结微转移比率；（2）淋巴结微转移与肿瘤大小、病理类型、细胞分化程度、部位、分型、分期进行Logstic回归分析，确定影响微转移的主要因素；（3）探讨微转移的方式、顺序。方法对91例非小细胞肺癌清扫的肺门和隆突下淋巴结进行MCK（AEI／AE3）免疫组化标志检测微转移的存在。另外收集45例肺部良性病变手术时切除的肺门淋巴结45枚和Ⅱ期、Ⅲ期肺癌常规病理检查阳性的肺门淋巴结45枚进行MCK（AEI／AE3）免疫组化（SP法）标志，分别作为阴性和阳性对照。结果45例肺部良性病变手术时切除的肺门淋巴结45枚进行MCK（AEI／AE3）免疫组化标志均为阴性；Ⅱ期和Ⅲ期常规病理检查阳性的肺门淋巴结45枚进行MCK（AEI／AE3）免疫组化标志均为阳性。91例Ⅰ期非小细胞肺癌总的微转移率为49％（45／91）。结论Ⅰ期非小细胞肺癌淋巴结中存在微转移；Ⅰb期非小细胞肺癌微转移率明显高于Ⅰa期；有必要对Ⅰb期非小细胞肺癌进行术后化疗；肿瘤分期和分化程度是影响淋巴结微转移的主要因素；淋巴结微转移遵循肺门到纵隔的途径；腺癌存在跳跃式微转移。     

VACUOLE SIGN AND SMALL NODE SIGN IN EARLY PERIPHERAL LUNG CANCER PATHOLOGIC BASIS AND DIAGNOSTIC VALUE

Radiologic and pathologic mani;estations of 30 peripheral pulmonary masses around l.5-3 cm in dia- meter were compared to the pathologic basis of va- cuole sign and small node sign on tomogram. Stati stics of 100 conventional X-ray tomograms of peri- pheral pulmonary masses about l-3 cm in diameter suggested that the vacuole sign and small node sign, more common in early peripheral lung cancer than in tuberculoma, are valuable for differentiating early peripheral lung cancer from tuberculoma.     

成本核算在医院管理中的应用和进展

目前,我国医疗总费用的增长速度大大超过了国民经济和财政收入的增长速度[1]。卫生经费投入不足,药费居高不下,政府、企业不堪重负,医疗制度改革势在必行。成本核算是医院经济管理的基础工作,核算工作的深度和层次直接影响医院成本管理的成效。1医疗成本核算的概念医疗成本是卫生服务过程中所发生的物化劳动和活劳动耗费的总和。它由以下6大类成本构成:劳务费、业务费、公务费、原材料费、固定资产折旧费和管理费。医疗成本核算是按照《医院财务制度》有关成本费用开支范围的规定,核算医院在医疗服务过程中所支出的物质消耗、劳务报酬以及有…     

"提高意识"活动在大学英语精读课中的体现 --对医学护理专业学生精读课改革的重新思考

语法翻译教学法多年来一直主宰着大学英语精读课的教学。随着中国经济突飞猛进的发展,各行各业的人们与国外同行交流的机会和要求也随之增加。面对社会发展而带来的这种变化,显然,古老传统的教学方法已不能适应。通过具体详尽的理论分析,对语法翻译教学法提出了自己的看法。     

Inhibition on Telomerase Activity and Cytotoxic Effects by Cisplatin in Cultured Human Choroidal Melanoma Cells

Purpose: To study the changes of telomerase activity and cytotoxic effects by Cisplatin; cis-dichlorodiamine platinum (CDDP) in cultured human choroidal melanoma. Material and Methods: The primary cultured human choroidal melanoma cells were cultured in the presence and absence of CDDP with different concentration and time respectively. The toxic effects were evaluated by MTT and the level of telormarse was detected by PCR-ELISA assay. And the relationship between telomerase activity and cytotoxic effects were analyzed by a correlation analysis.Results: Following the increase of the concentration and the time of CDDP, gradually repressed telomerase activity was detected in cultured cells. Meanwhile, the restrain rate of the cells increased. The telomerase activity at 24h and 1μg/ml was repressed significantly compared with the control cells. However, the appearance of cell death lagged behind the decreasing of telomerase.Conclusions: CDDP is an effective telomerase inhibitor in cultured choroidal melan     

青少年型帕金森病的临床特征

Anatomic and spiral computed tomographic study of the genial tubercles for genioglossus advancement.

OBJECTIVE: To measure and compare Chinese mandibular genial tubercles measured anatomically and with computed tomography (CT). STUDY DESIGN AND SETTING: Spiral CT scans were taken of 40 adult human skulls; the superior genial spines were measured using anatomic and CT methods. RESULTS: The height and width of the superior genial spines, mandible thickness, and distance from the menton to the inferior and superior margins of the superior genial spines were 5.82 +/- 0.71, 6.98 +/- 1.35, 11.95 +/- 1.59, 11.08 +/- 2.05, and 16.91 +/- 2.30 mm from anatomic measurements and 6.17 +/- 0.71, 7.01 +/- 1.13, 12.19 +/- 1.64, 10.41 +/- 1.55, and 15.73 +/- 2.12 mm using spiral CT, respectively. The anatomic and CT measurements were correlated. CONCLUSION: Spiral CT of the genial tubercles can help locate the osteotomy in genioglossus advancement. SIGNIFICANCE: This study acquired reference data on Chinese genial tubercles demonstrating that CT measurements of the genial tubercles reflect their anatomy, which should allow accurately locate the osteotomy.
