应用输尿管镜放置双J管早期治疗输尿管阴道瘘

Objective To evaluate the clinical effect of placing double J stent using a ureteroscope in early managing ureterovaginal fistula.Methods Twenty-eight patients cases with ureterovaginal fistula from 2002 to 2008 were treated early with placing double J stent using a ureteroscope and the clinical data were reviewed.Results Twenty-two of 28 cases were treated and double J stent was placed in them by a uretero-scope and 75% (21/28)of cases were cured.Four of 21 cases were treated twice by a ureteroscope and were cured finally.7 cases with failure ureterovaginal treatment underwent ureterocystostomy and were cured.The follow-up from 6 months to 33 months (average 10.1±6.4 months)showed that all of the 28 cases had been cured and had no urinary fistula.Conclusion Placing double J stent using a ureteroscope is the first choice of operative procedure for the early treatment of ureterovaginal fistula.     

血清瘦素在男生青春发育期的动态观察

目的 探讨血清瘦素在男生青春期发育中的作用。方法 健康男生170名，调查首次遗精时间，测定血清瘦素、睾酮、促卵泡成熟激素、黄体生成激素水平，采用多元Logistic回归模型分析男生青春期发育的影响因素；同时，连续两年观察，分析血清瘦素在青春期的动态变化。结果 末次研究已遗精组血清瘦素、睾酮、促卵泡成熟激素、黄体生成激素水平均明显高于未遗精组。多因素分析显示血清瘦素、睾酮、促卵泡成熟激素、体重为男生青春期发育的独立影响因素。初次资料分析，遗精前组血清瘦素、睾酮明显高于未遗精组。结论 血清瘦素、睾酮、促卵泡成熟激素、体重为男生青春期发育的独立影响因素，男生遗精前期血清瘦素、睾酮已有明显改变。

Association of the expressions of platelet-derived growth factor receptor and c-Fos with the biological characteristics of bladder cancer.

OBJECTIVE: To elucidate the relation of platelet-derived growth factor receptor (PDGFR) and c-Fos protein expressions with human bladder transitional epithelial cell carcinoma (BTCC). METHODS: The expressions of PDGFR and c-Fos were investigated in 11 normal bladder tissue samples, 14 adjacent non-carcinoma tissues and 43 BTCC tissues by means of SP immunohistochemical technique. RESULTS: The c-Fos expression was found in the cell nuclei and cytoplasm, and PDGFR in the nuclear membrane, cytoplasm, and cellular membrane. PDGFR and c-Fos were detected in 81.40% and 48.83% of the BTCC tissues respectively, at the rates both significantly higher than those in normal and adjacent non-carcinoma tissues (P<0.05). Correlation between the expression of c-Fos and the tumor grading was noted (P<0.05). The expressions of PDGFR and c-Fos in tumor blood vessels were significantly higher than those in normal vessels. CONCLUSIONS: The expressions of PDGFR and c-Fos might be involved in the development of BTCC, possibly related to the angiogenesis of the tumors. c-Fos expression can indicated the cell proliferative status of the BTCC.     

人端粒酶逆转录酶在肿瘤免疫治疗中的应用

寻找有效的抗原表位是近期肿瘤免疫治疗的热点．人端粒酶逆转录酶(hTERT)的免疫学特性使其成为肿瘤免疫治疗中一个吸引人的目标。从人和鼠系统获得的数据证实，细胞毒淋巴细胞(CTL)能识别hTERT特异的肽并杀死多种组织类型hTERT表达的肿瘤细胞。由于hTERT在人肿瘤组织中的广泛表达，在极少正常组织的低水平表达，临床试验已开始检验将hTERT作为肿瘤免疫治疗目标的可行程度。近期树突状细胞(DC)转运系统及其相关技术的发展和成熟提供了一个快速有效筛选抗原肽的方法。     

静脉药物配置中心的建立在临床中的应用

静脉输液药物集中配置、管理是我国医院管理的一项新举措.长期以来,临床静脉输液中的加药工作一直是由护士在治疗室独立完成,这种方式存在着很多不足之处.在这种环境污染下,职业健康安全管理越来越受到各国政府的重视.为了提高服务质量,预防和控制可能存在的环境污染及职业健康安全风险,国家颁布 GB/T24001～ 1996<环境管理体系规范和使用指南>, GB/T28001-2001<职业健康安全管理体系规范>标准,引进国外的先进管理模式,此项工作由药师和护士共同完成,以期达到合理用药减少药物的流失和浪费,科学配置、降低输液反应.静脉药物配置中心把静脉药物配置从普通环境的治疗室转为在具有洁净条件的配置中心进行集中管理配置,保证配置出来的药品安全无菌、有效.需要输液的患者在舒适、整洁和安静的环境下进行输液,减少临床护理工作量的目的,把更多的时间还给病人.这为顺利实施静脉配置中心的项目提供了保障,确保了输液中心正常运行.     

Norepinephrine transporter and α2c adrenoceptor allelic variants and personality factors

It has been suggested that reward dependence, as measured by the Tridimensional Personality Questionnaire (TPQ), is related to central noradrenergic activity, a proposition supported by two studies of urinary norepinephrine metabolite. In the current investigation, 190 normal young Han Chinese were examined, with genetic polymorphisms determined for the norepinephrine transporter (1287G/A) and the α_2c‐adrenoceptor (Del322–325) to test the association with TPQ personality traits. No significant association was demonstrated for these two polymorphisms and any of the TPQ personality‐factor scores, including reward dependence and its subscales. Our negative findings suggest that the investigated polymorphisms of the norepinephrine transporter and the α_2c adrenoceptor do not play a major role in the reward‐dependence personality trait as assessed by TPQ. © 2002 Wiley‐Liss, Inc.
