心肺复苏早期应用氨茶碱与传统方法的比较研究

目的探讨心肺复苏(CPR)早期应用氨茶碱的临床意义.方法将100例心脏骤停(CA)患者,随机分成观察组(肾上腺素+氨茶碱组)、对照组(肾上腺素组),对照组按照传统CPR方法,静脉注射肾上腺素;观察组在传统方法的基础上早期加用氨茶碱静注.对两组在6h、24h存活率及正常出院方面进行统计学分析. 结果①两组在性别、年龄、疾病构成方面无统计学差异(P＞0.05);②两组在肾上腺素剂量、开始使用时间、直流电除颤等方面比较无统计学差异(P＞0.05);③观察组6h存活率与对照组比较有显著性差异(P＜0.05);两组24h存活率无统计学差异,但在正常出院方面观察组略优于对照组.结论①早期使用氨茶碱可提高6h存活率,正常出院略优于单使用肾上腺素组(对照组);②早期使用氨茶碱可能对最终生存率有益.     

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.

调Q倍频Nd：YAG激光治疗太田痣的副反应及相关因素的探讨

观察调Q倍频Nd：YAG激光治疗太田痣的副反应及其相关因素。方法回顾性分析750例患者经调Q倍频Nd：YAG激光治疗后的副反应及其与治疗次数、治疗能量的关系。结果750例接受治疗的患者中发生副反应者76例(10．1％)，其中暂时性色素沉着55例(7.3％)，暂时性色素减退18例(2.4％)，永久性色素减退1例(0.1％)，萎缩性瘢痕2例(0.3％)。出现副反应与治疗次数无关，与治疗能量有关。结论副反应的出现与激光治疗本身没有特异性关系，随治疗能量的增加副反应发生率上升。调Q倍频Nd：YAG激光治疗太田痣无连续激光治疗后所致的增生性瘢痕、持续性色素沉着等副反应，用于治疗太田痣是安全的。

细胞荧光素酶报告基因试验受CpG岛甲基化状态影响

Objective To investigate the effects of methylation status of CpG islands of endogenous E-cadherin (CDH1) gene on the promoter activity of corresponding genes in reporter assays. Methods The methylation statuses of CpG island of CDHI in 8 different cell lines were detected by methylation-specific PCR. CDH1 protein was analyzed by Western blotting. Two sets of pGL3 reporter vectors with different genotypes/haplotypes of the CDH1 promoter were constructed [pGI3-A(-73)/-C(-73)pGL3-H1/-H4]and used to transfect these cell lines. The differences between these promoter reporter vectors were analyzed by t-test. Results (1) CDH1 CpG island was unmethylated in AGS, MCF7, MKN74, and PC-3 cell lines,expressed in MCF7, MKN74, and PC-3 ,but not in AGS. Expression of CDH1 was silenced by methylation in HeLa, BGC823, A549, and RKO cell lines. (2) In the four CDH1 -unmethylated MCFT, M KN74, PC-3, and AGS cell lines ,the promoter activities of pGI3-C(-73)(as 0. 78±0. 10,0. 17±0.01,0. 11±0. 01,1.19±0. 18)were significantly higher than those of pGL3-A(-73)(as 0. 30±0. 08,0. 07±0. 01,0. 07±0. 01,0. 39±0. 04) (t values are -6. 298, -12. 349, -8. 128, -7.388, and P<0. 01). However, in the four C DH1 -methylated HeLa, BGC823, A549, and RKO cell lines, the promoter activity of pGL3-C(-73)(as 0. 09±0. 02,0. 13±0. 02,0. 05±0. 01,0. 01±0. 00) was significantly lower than that of pGL3-A(-73)(as 0. 16±0. 01,0.25±0.01,0. 11±0.03,0.03±0.00) (t valued at 5.958,11. 189,3. 661,13. 866,and P<0.05). (3) In the unmethylated MKN74 and methylated RKO cell lines, the promoter activities of pGI3-H1/-H4 were obviously and contrarily different(as 1.57±0. 23/0. 94±0. 06 and 0. 38±0. 02/0. 50±0. 04 ,t values were 4. 577 and -4. 915 ,P values were 0. 010 and 0. 003). Conclusion The methylation status of CpG island of the target gene in the tested cell lines affects the promoter activity in Reporter Assay significantly. The most active one may be the most suppressive one.
